Effectiveness of Chinese Herbal Medicine as a Complementary Treatment for Neutropenia Prevention and Immunity Modulation During Chemotherapy in Patients With Breast Cancer: Protocol for a Real-World Pragmatic Clinical Trial.

In recent years, advancements in cancer treatment have enabled cancer cell inhibition, leading to improved patient outcomes. However, the side effects of chemotherapy, especially leukopenia, impact patients' ability to tolerate their treatments and affect their quality of life. Traditional Chinese medicine is thought to provide complementary cancer treatment to improve the quality of life and prolong survival time among patients with cancer. This study aims to evaluate the effectiveness of Chinese herbal medicine (CHM) as a complementary treatment for neutropenia prevention and immunity modulation during chemotherapy in patients with breast cancer. We will conduct a real-world pragmatic clinical trial to evaluate the effectiveness of CHM as a supplementary therapy to prevent neutropenia in patients with breast cancer undergoing chemotherapy. Patients will be classified into CHM or non-CHM groups based on whether they received CHM during chemotherapy. Using generalized estimating equations or repeated measures ANOVA, we will assess differences in white blood cell counts, absolute neutrophil counts, immune cells, and programmed cell death protein 1 (PD-1) expression levels between the 2 groups. This study was approved by the research ethics committee of Hualien Tzu Chi Hospital (IRB 110-168-A). The enrollment process began in September 2021 and will stop in December 2024. A total of 140 patients will be recruited. Data cleaning and analysis are expected to finish in the middle of 2025. Traditional Chinese medicine is the most commonly used complementary medicine, and it has been reported to significantly alleviate chemotherapy-related side effects. This study's findings may contribute to developing effective interventions targeting chemotherapy-related neutropenia among patients with breast cancer in clinical practice.

Efficacy and safety of Chinese herbal medicine as adjunctive therapy in sepsis patients with bloodstream infection: a propensity-matched analysis.

To investigate the efficacy and safety of Chinese herbal medicine in treating sepsis patients with bloodstream infection. A 6-year retrospective study was carried out at a university hospital in China. Adult sepsis patients with bloodstream infection were included. The primary outcome was 28-day mortality after admission. Propensity score method was used to adjust for possible confounding. 28-day mortality was estimated by Kaplan-Meier analysis and compared using the log-rank test. Cox regression analysis was carried out to identify factors impacting in-hospital mortality outcomes. Following the application of the propensity score method, a total of 176 patients were included. The all-cause 28-day mortality in the control group and Chinese herbal medicine group was 21.6% and 14.8%, respectively. Kaplan-Meier survival analysis showed that Chinese herbal medicine was associated with a lower hazard ratio (HR) in all-cause 28-day death compared with the control group [HR = 0.44, 95% CI(0.22, 0.90), P < 0.05]. The complications were similar between the two groups (P >0.05). Blood-activating and stasis-eliminating herb administration was associated with reduced in-hospital mortality among sepsis patients with bloodstream infection [HR = 0.54, 95% CI(0.34, 0.94), P < 0.05]. Chinese herbal medicine, especially the blood-activating and stasis-eliminating herb, might have certain efficacy and safety in treating sepsis patients with bloodstream infection. Clinicians should prescribe blood-activating and stasis-eliminating herb in treating these two coalescent critical diseases as long as no contraindications exist. However, further studies are needed to validate our results.

Effectiveness of Chinese Herbal Medicine in Postoperative Fatigue Syndrome Following Total Joint Arthroplasty or Hip Fracture Surgery: Evidence from Randomized Controlled Trials.

There is no high-quality, evidence-based protocol for the treatment of postoperative fatigue syndrome (POFS) after total joint arthroplasty (TJA) or fracture surgery with Chinese herbal medicine (CHM). The purpose of this study was to explore the efficacy of CHM in the treatment of POFS after TJA or hip fracture surgery (HFS). We searched six databases to obtain randomized controlled trials (RCTs) of CHM for the treatment of POFS after TJA or HFS. The retrieval time limit was from the establishment of each database to August, 2022. According to the Cochrane Handbook for Systematic Reviews version 5.1, we used RevMan 5.3 to evaluate the quality of the studies. Stata 14.0 software was used to merge and analyze the data. The weighted mean difference (WMD) was the effect estimate for statistical analysis. We also performed subgroup analyses according to different types of surgeries. A total of 11 RCTs were included in this study, comprising 430 cases in the CHM group and 432 cases in the control group (CG). The meta-analysis results showed that there was no significant difference in the Brief Profile of Mood States (BPOMS) score (WMD=0.08, 95% confidence interval (CI): -0.29 to 0.45, P=0.688), Christensen Fatigue scale (CHFS) score (WMD = 0.15, 95% CI: -0.09 to 0.39, P=0.214) or Identity-Consequence Fatigue Scale (ICFS) score (WMD=-0.40, 95% CI: -1.84 to 1.05, P=0.589) between the CHM group and the CG on the first postoperative day. The use of CHM significantly reduced the BPOMS score (WMD=-0.85 and WMD=-3.01, respectively), CHFS score (WMD=-1.01 and WMD= -1.45, respectively), and ICFS score (WMD=-3.51 and WMD=-5.26) on postoperative days 3 and 7. Compared with the CG, the CHM group had significantly increased serum transferrin and IgG levels on postoperative days 3 and 7. The subgroup analysis results suggested that the application of CHM in HFS patients improved fatigue symptoms on postoperative days 3 and 7, while the application of CHM to treat POFS in TJA patients had great inconsistency in the evaluation of different indicators. The application of CHM improved the fatigue status of POFS patients after TJA or HFS and increased the levels of transferrin and IgG in serum, which is conducive to promoting the postoperative rehabilitation process of patients. The subgroup analysis results showed that the application of CHM to intervene in POFS in HFS patients had obvious benefits.

Association between Chinese herbal medicine (CHM) treatment and depression among cancer patients in China: An outpatient-based cross-sectional study.

Depression is a prevalent condition among cancer patients and significantly impacts their quality of life. Traditional Chinese Medicine, particularly Chinese Herbal Medicine (CHM), has shown potential in both anti-tumor and anti-depressive effects. However, there is a dearth of scientific literature exploring the association between CHM treatment and depression in cancer patients. This study aims to investigate the relationship between CHM treatment and depression in cancer patients. A cross-sectional study was conducted among cancer outpatients at Longhua Hosiptal, Shanghai University of Traditional Chinese Medicine, from June 2020 to April 2021 (Ethical approval number: 2020LCSY057). All patients signed informed consent and completed The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (EORTC QLQ-C30). Hamilton depression scale was evaluated depression by psychiatrists. The power of the sample size was determined using Gpower statistical and SPSS were used for statistical analysis. A total of 809 completed the study. Gender, medical insurance, the classification of time since diagnosis, ECOG, cancer stage, metastasis, gene mutation, treatment plan and CHM treatment were an important factor affecting depression (P < .05). Further analysis investigated the impact of CHM treatment on depression. There were 374 enrolled in CHM group and 435 enrolled in Non-CHM group. The assessment results of Hamilton depression scale and EORTC QLQ-C30 in CHM group were superior to those in Non-CHM group. The morbidity of depression is 50.27% in CHM group and 66.44% in Non-CHM group. After adjusting for potential confounders (gender, medical insurance, cancer stage, etc.), CHM treatment indicated negative correlation with depression (Odds ratio (OR) = 0.7, 95% confidence interval (CI): 0.5-0.9, P = .020). The interaction effects within each subgroup were no significantly affect the relationship between CHM treatment and depression (P > .05). CHM treatment was an independent protective factor for depression in cancer patients, and lead to better quality of life for cancer patients.

The Effect of Chinese Herbal Medicine on Traumatic Anosmia: A Prospective, Randomized Clinical Trial.

Chinese herbal medicine (CHM) has been implemented as a form of treatment for olfactory dysfunction. In this study, we aimed to use a tailored Guizhi decoction for the treatment of traumatic olfactory dysfunction. Patients who had lost olfactory function after experiencing head trauma and whose olfactory function was anosmic were selected. The eligible patients were randomly assigned to two groups. In the CHM group, a tailored Guizhi decoction was prescribed, with patients also undergoing olfactory training (OT). In the OT group, patients performed OT only. The olfactory function of each patient was evaluated by both the phenyl ethyl alcohol (PEA) odor detection threshold test and the traditional Chinese version of the University of Pennsylvania Smell Identification Test (TC-UPSIT), at both 3 and 6 months after the completion of treatment. A total of 38 patients in the CHM group and 40 in the OT group completed the study. The TC-UPSIT scores of patients slightly rose after treatment in both the CHM and OT groups. Nevertheless, there were no significant differences in TC-UPSIT scores before and after treatment in both groups. However, the PEA thresholds improved significantly in both CHM and OT groups (p=0.005 and 0.016, respectively). Of note, there were no significant differences in threshold or identification scores between the CHM and OT groups. Our results show that adding a tailored Guizhi decoction to OT conferred a limited benefit to the olfactory function of patients experiencing traumatic anosmia. 2 Laryngoscope, 2023.

Acupuncture and Chinese herbal medicine for menopausal mood disorder: a randomized controlled trial

Objective This study aimed to analyze the effectiveness of acupuncture combined with Chinese herbal medicine (CHM) on mood disorder symptoms for menopausal women. Methods A total of 95 qualified Chinese participants were randomly assigned to one of three groups: 31 in the acupuncture combined with CHM group (combined group), 32 in the acupuncture combined with CHM placebo group (acupuncture group) and 32 in the CHM combined with sham acupuncture group (CHM group). The patients were treated for 8 weeks and followed up for 4 weeks. The data were collected using the Greene Climacteric Scale (GCS), self-rating depression scale (SDS), self-rating anxiety scale (SAS) and safety index. Results The three groups each showed significant decreases in the GCS, SDS and SAS after treatment (p < 0.05). Furthermore, the effect on the GCS total score and the anxiety domain lasted until the follow-up period in the combined group (p < 0.05). Within the three groups, there was no difference in GCS and SAS between the three groups after treatment (p > 0.05). However, the combined group showed significant improvement in the SDS, compared with both the acupuncture group and the CHM group at 8 weeks and 12 weeks (p < 0.05). No obvious abnormal cases were found in any of the safety indexes. Conclusions The results suggest that either acupuncture, or CHM or combined therapy offer safe improvement of mood disorder symptoms for menopausal women. However, the combination therapy was associated with more stable effects in the follow-up period and a superior effect on improving depression symptoms.

Effectiveness of Chinese Herbal Medicine in Patients with COVID-19 During the Omicron Wave in Hong Kong: A Retrospective Case-Controlled Study.

SARS-CoV-2 Omicron led to the most serious outbreak of COVID-19 in Hong Kong in 2022. Under the pressure of a high volume of patients and limited medical resources, Chinese herbal medicine (CHM) has been extensively used. This is a case-control study of the infected patients that aims to evaluate the effectiveness of CHM using data extracted from the Hong Kong Baptist University Telemedicine Chinese Medicine Centre database. Patients with COVID-19 confirmed by either a rapid antigen test or a polymerase chain reaction who had completed two consultations and taken CHM within 10 days of the first positive test were included in the study (CHM group, [Formula: see text]). The matched control cases were those who did not take CHM within 10 days of the first positive test and were based on age ([Formula: see text] 3 years), vaccine doses ([Formula: see text] 3 doses, or 3 doses), and gender (no-CHM group, [Formula: see text]). The outcomes included the negative conversion time (NCT, primary outcome), total score of individual symptoms, number of the reported symptoms, and individual symptom disappearance rates. The NCT of the CHM group (median days: 7.0, interquartile range: 6.0-8.0) was significantly shorter than that of the no-CHM group (8.0, 7.0-10.5; [Formula: see text]). CHM treatment significantly reduced the total score of individual symptoms ([Formula: see text]) and the number of the reported symptoms ([Formula: see text]) as compared with that of the no-CHM group. Additionally, the symptom disappearance rates of symptoms such as chills, cough, sputum, dry throat, itching throat, headache, chest tightness, abdominal pain, diarrhea, and fatigue were significantly higher in the CHM group than in the no-CHM group. In conclusion, CHM intervention can significantly reduce NCT and COVID-19 symptoms. Chinese medicine can be accurately prescribed based on a telemedical consultation.

Chinese Herbal Medicine Combined with Intravitreal Antivascular Growth Factor Agents in Treatment of Macular Edema Secondary to Retinal Vein Occlusion: A Systematic Review and Meta-Analysis

Background. Retinal vein occlusion (RVO) is the second most common retinal vascular disease in the world after diabetic retinopathy. Moreover, macular edema (ME) is the main cause of visual impairment in RVO patients. Intravitreal injection of antivascular endothelial growth factor (VEGF) agents is recommended for RVO-ME. However, repeated injections severely limit their efficacy. Chinese herbal medicine (CHM) is widely used in RVO-ME as adjuvant therapy in China. Objective. The study aims to evaluate the efficacy and safety of anti-VEGF combined with CHM for RVO-ME and to provide reliable evidence for clinical application. Methods. Seven databases were searched without language or publication status restrictions. Randomized controlled trials (RCTs) comparing anti-VEGF combined with CHM (anti-VEGF + CHM) versus anti-VEGF in participants with RVO-ME were included in this study. The “risk of bias assessment tool” of the Cochrane Handbook was applied to assess the quality of included trials, and RevMan 5.3 software was used for data analysis. Results. A total of 10 relevant trials with 743 patients were identified. The results showed that BCVA of the anti-VEGF + CHM group significantly improved at 3 months ( P &lt; 0.00001 ), 6 months ( P = 0.008 ), and 12 months ( P = 0.01 ), and CMT significantly reduced at 1 month ( P = 0.02 ), 2 months ( P = 0.0009 ), 3 months ( P &lt; 0.05 ), 6 months ( P &lt; 0.0001 ), and 12 months ( P &lt; 0.00001 ) compared with the anti-VEGF group alone. At the same time, the anti-VEGF + CHM group has a better performance in reducing the number of injections ( P &lt; 0.05 ) and improving the total effective rate ( P &lt; 0.0001 ). However, regarding adverse events, there was no statistical difference between the two groups ( P = 0.09 ). Conclusions. Our results provide promising evidence that anti-VEGF therapy combined with CHM may be more beneficial to patients than anti-VEGF therapy alone. However, because of the low quality and small sample size of the included studies, more rigorous and larger-scale trials were necessary to validate our results. Registration Number. CRD42021270262.

Chinese herbal medicine reduces the risk of readmission in patients with rheumatoid arthritis combined with hyperlipidemia: A population‑based retrospective cohort study.

Rheumatoid arthritis (RA) is a systemic autoimmune disease that is associated with high degrees of disability and mortality. Patients with RA are generally more prone to a multitude of comorbidities, with hyperlipidemia (HL) one of the most frequently observed. Therefore, the present study investigated the possible association between Chinese herbal medicine (CHM) treatment and the risk of readmission in patients with RA combined with HL (RA-HL). The aim of the present study was to potentially provide an evidence-based strategy for decreasing the risk of readmission in patients with RA-HL. The present study enrolled 839 patients with RA admitted to the First Affiliated Hospital of the Anhui University of Chinese Medicine from June 2014 to June 2015. Subsequently, 425 patients with RA were included into the present study after those with incomplete follow-up and laboratory parameter data were excluded. These 425 patients were then classified into the RA-HL and RA-non-HL groups, before incidences of sex distribution, age group, medication and readmission with propensity score matching were all compared. In total 263 patients with RA-HL were then included and arranged into the CHM and non-CHM groups. In particular, the variables of age, sex and diagnosis year between one patient in the CHM group and one in the non-CHM group were adjusted with propensity score matching to decrease selection bias and interference from confounding factors. Finally, 127 patients with RA-HL were included into the CHM group and 127 patients with RA-HL were allocated into the non-CHM group. The proportion of readmitted patients (including RA-HL and RA-non-HL, RA-CHM and RA-non-CHM) was analyzed and compared using the χ2 test and Kaplan-Meier curves. Bivariate logistics regression analysis was used to evaluate the possible factors that can influence the readmission of patients with RA-HL, whereas the potential association between CHM and improvements in the clinical indicators of the patients with RA-HL was assessed using association rules based on Apriori algorithm. It was found through the follow-up data that patients with RA-HL were at higher risk of readmission compared with that in those with RA-non-HL (P<0.05). The CHM treatments included both oral CHM decoction and Chinese patent medicine, including Xinfeng capsule and Huangqin chubi capsule, which may reduce the risk of readmission and improve the recovery of immune-inflammatory indicators in patients with RA-HL (P<0.05). Overall, CHM, as a protective factor, is associated with a reduced risk of readmission in RA-HL.

Contribution of Chinese herbal medicine in the treatment of coronavirus disease 2019 (COVID-19): A systematic review and meta-analysis of randomized controlled trials.

Coronavirus disease 2019 (COVID-19) has become a global epidemic, and there is no specific treatment for anti-COVID-19 drugs. However, treatment of COVID-19 using Chinese herbal medicine (CHM) has been widely practiced in China. PubMed, Embase, Cochrane Library, CNKI, Wanfang and VIP databases were searched to evaluate the efficacy and safety of CHM in the treatment of COVID-19. Twenty-six studies were included in this meta-analysis. The included cases were all patients diagnosed with COVID-19 according to the "New Coronary Virus Pneumonia Diagnosis and Treatment Program," with a total of 2,407 cases. Patients were treated with CHM, including 36 prescriptions, and 105 flavors of CHM were included. The results of the meta-analysis showed that the CHM group improved in lung CT, clinical cure rate, clinical symptom score and time to negative for viral nucleic acid. However, this study still has many limitations due to the limited number of included studies. Therefore, high-quality RCT studies are needed to provide more reliable evidence for CHM treatment of COVID-19. In conclusion, CHM may significantly improve the clinical manifestations and laboratory indicators of patients with COVID-19. In addition, no serious adverse reactions were found after CHM treatment. Therefore, CHM may be used as a potential candidate for COVID-19. HIGHLIGHTS: COVID-19 has become a global epidemic, and there is no specific treatment for anti-COVID-19 drugs. CHM has made a new breakthrough in the treatment of COVID-19. CHM may relieve lung CT images of COVID-19 patients. CHM may improve clinical symptoms of COVID-19 patients. CHM may inhibit the expression of inflammatory factors in patients with COVID-19.

Chinese herbal medicine is associated with higher body weight reduction than liraglutide among the obese population: A real-world comparative cohort study.

Introduction: In Taiwan, many people receive Chinese herbal medicine (CHM) as an alternative choice to help control body weight. However, the clinical effectiveness of CHM on weight control has not been well studied, while potential risks and adverse effects are still unknown. The aim of our study is to find out a safe and efficient treatment model of CHM for weight control compared to liraglutide in a real-world setting. Methods: we retrospectively analyzed obese subjects [body mass index (BMI)≧25 kg/m2] from Chang Gung Research Database (2013–2018). We evaluated the effect on body weight and BMI changes in obese groups receiving CHM or western medicine (WM, represented liraglutide) within 180 days. The proportion of subjects who achieved 5 and 10% weight reduction was calculated as well. Furthermore, the potential adverse events were analyzed during the study period. Overlap weighting was used to balance the baseline differences between CHM and WM groups. Results: The full cohort comprised 1,360 participants: 701 in the CHM group and 659 in the WM group. At baseline, the CHM group was younger (42.75 ± 12.12 years old in CHM vs. 52.31 ± 11.7 years old in WM, p-value <0.001) and has more female subjects (77.6% in CHM vs. 53.0% in WM, p-value <0.001). On the other hand, CHM users had lower body weight (79.83 ± 15.66 kg vs. 84.68 ± 17.14 kg, p-value <0.001) and BMI (30.58 ± 5.20 vs. 32.84 ± 6.95, p-value <0.001). At day 180, CHM users lost more body weight (−4.5 ± 4.07 kg vs. −2.15 ± 4.05 kg, p-value <0.001) and higher reduction in BMI (−1.77 ± 1.73 vs. −0.9 ± 2.14, p-value <0.001). A total of 53.21% (n = 373) CHM users lost at least 5% of body weight (22.46% for WM users, p-value <0.001), and 18.97% (n = 132) lost at least 10% of body weight (4.55% for WM users, p-value <0.001). The benefit remained consistent with and without overlap weighting. For adverse events, 18 cases of hypertension occurred in 659 subjects in the WM group (2.7%) in comparison to 1 of 701 subjects in the CHM group (0.1%). Conclusion: CHM led to clinically meaningful weight loss without serious adverse events in a real-world setting. Further clinical trials are warranted to validate this result.

Lower risk of ischemic stroke among patients with chronic kidney disease using chinese herbal medicine as add-on therapy: A real-world nationwide cohort study.

Background: The incidence of ischemic stroke (IS) is much higher among patients with chronic kidney disease (CKD) compared to the general population. Few studies have evaluated the association between the risk of IS and the use of Chinese herbal medicine (CHM) in patients with CKD. We aimed to investigate the risk of IS among patients with CKD using CHM as add-on therapy. Methods: We conducted a retrospective cohort study based on Taiwan’s National Health Insurance Research Database to assess 21,641 patients with newly diagnosed CKD between 2003 and 2012. Patients were classified as either the CHM (n = 3,149) or the non-CHM group (n = 3,149) based on whether they used CHM after first diagnosis of CKD. We used the proportional subdistribution hazards model of Fine and Gray to examine the hazard ratio (HR) of IS in propensity-score matched samples at a ratio of 1:1 for two groups. Results: The risk of IS was significantly reduced in the CHM group (adjusted HR [aHR]: 0.58, 95% confidence interval [CI]: 0.48–0.70) compared with the non-CHM group. Those who used CHM for >180 days had an even lower risk of IS than those in the non-CHM group (aHR: 0.51, 95% CI: 0.41–0.63). Additionally, frequently prescribed formulae, such as Ji-Sheng-Shen-Qi-Wan, Liu-Wei-Di-Huang-Wan, and Zhen-Wu-Tang were associated with a 30%–50% reduced risk of IS. Conclusion: Our results suggest that patients with CKD who used CHM as add-on therapy had a lower hazard of IS than those in the non-CHM group, especially for patients taking CHM for >180 days. Further experimental studies are required to clarify the causal relationship.

Clinical characteristics and prognosis analysis of 498 cases with drug-induced liver injury

Objective: To determine the risk factors, clinical characteristics and treatment prognosis, so as to provide reference for clinicians to diagnose, treat and prevent drug-induced liver injury (DILI). Methods: Data of 712 confirmed DILI cases were collected from the Second Affiliated Hospital of Kunming Medical University between 2013 to 2019. Among them, 498 cases were included in the study. All patients medical history, clinical manifestations and classification, laboratory parameters, disease severity, and mortality rate were collected. Statistical analysis was performed using t-test, Mann-Whitney U test/Pearson χ2 test/Fisher's exact test or Spearman's rank test. Results: Among the suspicious drugs causing DILI, single medication accounted for 89.56%, mainly including traditional Chinese medicine (56.43%), anti-tumor and immunomodulatory agents (8.03%), anti-infective drugs (4.42%), antipyretic and analgesic drugs (4.22%) %), etc., while combination medication accounted for 10.44%. The clinical classification was dominated with hepatocyte injury (63.05%), and there was a statistically significant difference in clinical classification among age groups (P<0.001). Age, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) and total bile acid (TBA) had statistically significant difference among different suspicious drugs in DILI caused by different drug (P<0.001, 0.003, 0.001, <0.001 and <0.001). Laboratory test results showed that there were statistically significant differences in ALT, AST, ALP, γ-glutamyltransferase (GGT), TBA, international normalized ratio (INR), and eosinophils (P<0.001, <0.001, <0.001, 0.018, 0.003 and 0.019, respectively). Chronic hepatitis was more common in the 54 cases who completed histopathological examination of the liver biopsy. Fibrosis degree was higher in the Western medicine group than Chinese herbal medicine group (P<0.05), and the difference was statistically significant (P<0.05). 96.99% of DILI patients were cured or improved, and 3.01% of patients were uncured. Ordinal logistic regression analysis showed that GGT and INR were independent predictors of poor prognosis. Conclusions: Suspicious drugs for DILI are herbal/dietary supplements, anti-tumor and immunomodulatory, anti-infective, and antipyretic and analgesic. The most common clinical classification is hepatocyte injury. Most patients with DILI have a good prognosis after drug withdrawal and GGT and INR are independent predictors of poor prognosis.

Chinese Herbal Medicine as an Adjunctive Therapy Improves the Survival Rate of Patients with Ischemic Heart Disease: A Nationwide Population-Based Cohort Study.

Background Ischemic heart disease (IHD) related to cardiovascular or cerebrovascular disease is the leading cause of mortality and an important issue of public health worldwide. The cost of long-term healthcare for IHD patients may result in a huge financial burden. Objectives To analyze the medical expenditure incurred for and survival of IHD patients treated with Chinese herbal medicine (CHM) and Western medicine. Methods Subjects were randomly selected from the National Health Insurance Research Database in Taiwan. The Cox proportional hazards regression model, Kaplan–Meier estimator, logrank test, chi-square test, and analysis of variance were applied. Landmark analysis was used to assess the cumulative incidence of death in IHD patients. Results We identified 11,527 users of CHM combined with Western medicine and 11,527 non-CHM users. CHM users incurred a higher medical expenditure for outpatient care within 1 (24,529 NTD versus 18,464 NTD, P value <0.0001) and 5 years (95,345 NTD versus 60,367 NTD, P value <0.0001). However, CHM users had shorter hospitalizations and lower inpatient medical expenditure (7 days/43,394 NTD in 1 year; 11 days/83,141 NTD in 5 years) than non-CHM users (11 days/72,939 NTD in 1 year; 14 days/107,436 NTD in 5 years). The CHM group's adjusted hazard ratio for mortality was 0.41 lower than that of the non-CHM group by Cox proportional hazard models with time-dependent exposure covariates. Danshen, Huang qi, Niu xi, Da huang, and Fu zi were the most commonly prescribed Chinese single herbs; Zhi-Gan-Cao-Tang, Xue-Fu-Zhu-Yu-Tang, Tian-Wang-Bu-Xin-Dan, Sheng-Mai-San, and Yang-Xin-Tang were the five most frequently prescribed herbal formulas in Taiwan. Conclusions Combining Chinese and Western medicine can reduce hospital expenditure and improve survival for IHD patients.

Effects of Chinese Herbal Medicine on ovarian functions in the patients with endometriosis: A systematic review and meta-analysis of randomized controlled trials

When using Chinese Herbal Medicine (CHM) to treat endometriosis, the effects of CHM on the ovarian function have received little attention. This systematic review and meta-analysis aimed to evaluate the effects and safety of CHM on the ovarian function in patients with endometriosis. Eight electronic databases were searched from their inception to March 2, 2021. We compared those receiving CHM with controls, all studies included were randomized controlled trials (RCTs). Statistical analysis was performed using standard mean difference of hormonal levels: Estradiol(E2), Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH). Subgroup analysis and sensitivity analysis were conducted. A total of 844 patients from 11 RCTs were included. In E2 levels, the analysis revealed a significant effect in favor of CHM group compared with the control group (SMD = 3.05, 95%CI = 0.29 to 1.32, P = 0.002). After subgroup analyses, there were still significant effects in both non-operative subgroup (SMD = 2.04, 95%CI = 0.04 to 1.88, P = 0.04) and post-operative subgroup (SMD = 2.19, 95%CI = 0.08 to 1.42, P = 0.03). There were no significant differences between the two subgroups in both FSH levels (P > 0.05) and LH levels (P > 0.05), and the subgroup analyses showed similar results. No adverse events were reported. CHM may improve ovarian function in patients with endometriosis through increasing E2 levels whether there is surgery or not, which may indicate a referable and safe treatment for endometriosis. Due to the weak evidence, high-quality clinical trials are needed to support this conclusion. (PROSPERO ID is CRD42021240162)

Traditional Chinese Medicine for HIV-Associated Acute Herpes Zoster: A Systematic Review and Meta-Analysis of Randomized Trials.

Background Herpes zoster (HZ) is a common infection in individuals with acquired immunodeficiency syndrome (AIDS) patients. Traditional Chinese medicine (TCM) has been used widely in clinical practice for HZ, which remains not supportive of evidence. This review aimed to evaluate the effectiveness and safety of TCM in treating HIV-associated HZ. Methods Nine electronic databases were searched for randomized controlled trials (RCTs) testing TCM in treating HIV-associated HZ. Data were extracted on citations, interventions, and outcomes, by two authors independently. For the quality evaluation, Cochrane risk-of-bias tool 2.0 was used. Meta-analyses were performed by Revman5.3 software. Effect estimation presented as risk ratio (RR) for dichotomous data and mean difference (MD) for continuous data with their 95% confidence interval (CI). Results Twelve RCTs (n = 644) were included; the majority of them had a high or unclear risk of bias. Meta-analysis showed that pain intensity (VAS 0–5) in the Chinese herbal medicine (CHM) group was lower than it in the drugs group (MD = −0.87, 95% CI [−1.69, −0.04], two trials, n = 93). Duration of herpes-related pain (days) of patients in the combination group was shorter than those in the drugs group (MD = −9.19, 95% CI [−16.73, −1.65], n = 144). The incidence of postherpetic neuralgia (PHN) in the combination group was lower than in the drugs group (RR = 0.49, 95% CI [0.25, 0.99], n = 202). As for cure rate (complete absence of pain and herpes), two trials showed that CHM was better than drugs (RR = 1.58, 95% CI [1.13, 2.22], n = 93), five trials showed combination treatment was better than drugs (RR = 1.40, 95% CI [1.08, 1.82], n = 224). The cure rate in the acupuncture group was more than that in the drugs group (RR = 1.99, 95% CI [1.18, 3.36], n = 120). Four trials reported adverse effects and found no serious adverse events occurred. Conclusion CHM and acupuncture demonstrate more benefits than drugs in pain relief, cure rate improvement, and incidence reduction of PHN. However, given the data limitation and TCM therapies' diversity, the conclusions need to be verified in future trials.

Chinese Herbal Medicine Combined With First-Generation EGFR-TKIs in Treatment of Advanced Non-Small Cell Lung Cancer With EGFR Sensitizing Mutation: A Systematic Review and Meta-Analysis.

Background: Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related deaths worldwide. First-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (EGFR-TKIs) significantly improve prognosis of advanced NSCLC patients harboring EGFR sensitizing mutation. However, acquired resistance to EGFR-TKIs limits the good outcomes. Chinese herbal medicine (CHM) has been used for NSCLC patients receiving EGFR-TKIs for more than 10°years as an adjuvant treatment.Methods: Studies were searched from China BioMedical Literature, Chinese National Knowledge Infrastructure, Cqvip Database, Wanfang Database, MEDLINE (PubMed), EMBASE (Ovid), Google Scholar, and Cochrane Library from inception to March, 2021. Randomized controlled clinical trials (RCT) comparing EGFR-TKIs + CHM (TKIs + CHM) versus EGFR-TKIs with/without placebo (TKIs ± placebo) in participants with advanced NSCLC harboring EGFR sensitizing mutation were included in this study. Two authors screened all references, assessed the risk of bias and extracted data independently. Data were summarized using hazard ratio (HR) and risk ratios (RR), with 95% confidence intervals (CI) for binary outcomes. Meta-analysis was performed using random effects model. Overall quality of evidence was assessed using GRADE.Results: A total of 9 RCTs (1137 participants, 581 in the TKIs + CHM group and 556 in the TKIs ± placebo group) were included in this review. Only first-generation EGFR-TKIs were included. Most trials included used oral CHM preparations to tonify Qi and/or Yin. Treatment lasted from enrollment until disease progression (PD) or intolerable adverse events (AE). Combination of CHM with EGFR-TKIs improved median progression-free survival (mPFS) (HR,0.59; 95% CI, 0.52–0.68; P < 0.00001) and objective response rate (ORR) (RR, 1.23; 95% CI, 1.13–1.34; P < 0.00001) compared with used of EGFR-TKIs ± placebo. CHM reduced AE associated with EGFR-TKIs such as cutaneous toxicity (RR, 0.58; 95% CI, 0.46–0.73; P < 0.00001) and diarrhea (RR, 0.43; 95% CI, 0.30–0.60; P < 0.00001).Conclusion: Combination therapy of CHM and EGFR-TKIs significantly delays acquired resistance while improving ORR to EGFR-TKIs. Furthermore, CHM reduces AE induced by EGFR-TKIs. More international multi-centered, double-blinded, placebo-controlled, well-designed clinical trials are needed in future research.

The Efficacy of Long-Term Chinese Herbal Medicine Use on Lung Cancer Survival Time: A Retrospective Two-Center Cohort Study with Propensity Score Matching.

Objective To explore the efficacy of long-term use of Chinese herbal medicine (CHM) on survival time of lung cancer. Methods We conducted a retrospective cohort study on lung cancer patients. A propensity score matching (PSM) was performed to balance the covariates. Progression-free survival (PFS) was the primary endpoint and overall survival (OS) was the secondary endpoint. Patients who received CHM therapy from the initial date of diagnosis of lung cancer were included in the CHM group. Patients who were not treated with CHM during the same interval were categorized in the control group. A Cox regression model was used to explore the prognostic factors related to lung cancer. Hazard ratios of different subgroups were also analyzed. Results A total of 1134 patients were included in our study: 761 patients were in the CHM group and 373 patients were in the control group. After PSM, the mPFS and mOS in the CHM group were 70.4 months and 129.1 months, respectively, while the mPFS and mOS in the control group were 23.8 months and 99.7 months, respectively. The results of survival analysis on each stage demonstrated that patients may benefit from the long-term CHM treatment especially for patients with early stage. One-year to ten-year progression-free survival rates in the CHM group were higher than those in the control group (p < 0.001). COX multivariate regression analysis indicated that CHM treatment, female, low age at diagnosis, early tumor stage, and surgery were independent protective factors against recurrence and metastasis of lung cancer. Subgroup analysis showed that CHM treatment could reduce the risk of recurrence and metastasis in each subgroup (p < 0.01). Conclusion Long-term CHM treatment with the Fuzheng Quxie Formula, which can be flexibly applied in the course of lung cancer treatment, not only has a positive influence on the progression-free survival time of lung cancer patients, but also reduces the risk of recurrence and metastasis of lung cancer.

A Randomized, Double-Blind, and Placebo-Controlled Trial of Chinese Herbal Medicine in the Treatment of Childhood Constipation.

OBJECTIVES:Management of constipation is still challenging in childhood. The pharmacological effect of XiaojiDaozhi Decoction, a prescription of Chinese Herbal Medicine (CHM), has been well described for the treatment of food and Qi stagnation which account for childhood constipation. However, the efficacy and safety of XiaojiDaozhi Decoction in childhood constipation remains unclear.METHODS:A randomized, double-blind, and placebo-controlled trial was conducted to evaluate the efficacy and safety of XiaojiDaozhi Decoction in childhood constipation. Two hundred children were recruited and randomly allocated to the CHM or placebo group to receive their respective interventions. The duration of treatment was 8 weeks, with a 12-week follow-up. Main outcome measures were complete spontaneous bowel movements and satisfaction with bowel function. Safety and adverse effects were evaluated by blood laboratory measurements.RESULTS:At the end of follow-up, the response rates of CHM and placebo were 62% and 31%, respectively (χ2 = 19.315, P < 0.01). At the end of treatment, recurrence was found in 7 cases (10.14%) in CHM and 11 cases (26.19%) in placebo (χ2 = 4.947, P < 0.05). In the main outcome measures, 56 patients (56%) in the CHM group and 25 patients (25%) in the placebo group were satisfied with their bowel movements (χ2 = 19.940, P < 0.05). Increased complete spontaneous bowel movements ≥3 per week from baseline were found in 40 patients (40%) who received CHM and 19 patients (19%) who received placebo (χ2 = 10.602, P < 0.05). No serious adverse effects were found in any of the recruited cases.DISCUSSION:CHM XiaojiDaozhi Decoction is a safe and effective method for the treatment of childhood constipation.

Chinese Herbal Medicine Decreases Incidence of Cirrhosis in Patients with Non-Alcoholic Fatty Liver Disease in Taiwan: A Propensity Score-Matched Cohort Study.

Objective: Chinese herbal medicine (CHM) is quite popular in Asia. The purpose of this study is to investigate the benefits of decreasing the risk of cirrhosis in patients with non-alcoholic fatty liver disease (NAFLD) by using CHM. Design: We performed a 1:3 propensity score-matched cohort study to analyze patients with NAFLD diagnosed between January 1, 1997 and December 31, 2011 through the Taiwanese National Health Insurance Research Database. Patients who received CHM therapy from the initial date of diagnosis of NAFLD to December 31, 2011 were included in the CHM group. Patients who were not treated with CHM during the same interval were categorized in the non-CHM group. Cox regression model was used to adjust for sex, age, comorbidities, and drug use. Hazard ratios were also compared between the two groups. Results: A total of 13,072 patients were identified after 1:3 propensity score matching. The patients had similar basic characteristics. A lower cumulative incidence of cirrhosis was found in the CHM cohort (log-rank test, p < 0.0001). Finally, 176 patients in the CHM cohort (4.66 per 1000 person-years) and 582 patients in the non-CHM cohort (7.92 per 1000 person-years) developed cirrhosis (adjusted hazard ratios 0.63, 95% confidence interval 0.53-0.75). The effect of CHM to lower cirrhosis incidence was independent of sex, drug use, and comorbidities, including diabetes mellitus, hypertension, and cardiovascular diseases. Patients older than 40 years of age and without comorbidities such as chronic obstructive pulmonary disease, hyperlipidemia, alcoholism, tobacco use, or obesity also benefited from CHM. Conclusions: Our study is the first large-scale investigation in Taiwan that shows the association between patients with NAFLD and cirrhosis prevention after CHM intervention. The results may be useful for treatment and for decision making for patients and clinical doctors. Further restricted trials are needed to support our findings.
