Establishment of Coloproctitis Cancer Model in Mice and Evaluation of Therapeutic Effect of Chinese Medicine.

Colorectal cancer (CRC) is a common malignancy of the digestive system and has become the third most common malignancy worldwide and the second leading cause of malignancy-related death. Ulcerative coloproctitis (UC) is a precancerous lesion, and UC-associated CRC (UC-CRC) is the most common subtype of CRC. Therefore, a reasonable UC-CRC model is the cornerstone and guarantee of new drug development. Traditional Chinese medicine (TCM) has been widely used in the treatment of UC-CRC due to its good efficacy. As a classic tonic prescription of TCM, Liujunzi decoction (LJZD) has been widely used in the treatment of UC-CRC. In this study, a UC-CRC model was established by combining azomethane and dextran sulfate sodium, and the LJZD was administered. The data confirmed that LJZD can effectively inhibit cancer transition in UC-CRC by using mouse body weight, colorectal length, pathological and inflammatory factors, colorectal barrier function, and cancer markers. This protocol provides a system for evaluating the efficacy of TCM in the prevention and treatment of UC-CRC.

Mechanism Study on Chinese Medicine in Treatment of Nodular Goiter.

Nodular goiter has become increasingly prevalent in recent years. Clinically, there has been a burgeoning interest in nodular goiter due to the risk of progression to thyroid cancer. This review aims to provide a comprehensive summary of the mechanisms underlying the therapeutic effect of Chinese medicine (CM) in nodular goiter. Articles were systematically retrieved from databases, including PubMed, Web of Science and China National Knowledge Infrastructure. New evidence showed that CM exhibited multi-pathway and multi-target characteristics in the treatment of nodular goiter, involving hypothalamus-pituitary-thyroid axis, oxidative stress, blood rheology, cell proliferation, apoptosis, and autophagy, especially inhibition of cell proliferation and promotion of cell apoptosis, involving multiple signal pathways and a variety of cytokines. This review provides a scientific basis for the therapeutic use of CM against nodular goiter. Nonetheless, future studies are warranted to identify more regulatory genes and pathways to provide new approaches for the treatment of nodular goiter.

An inspiration to the studies on mechanisms of acupuncture and moxibustion action derived from 2021 Nobel Prize in Physiology or Medicine

Abstract The editorial board of Acupuncture and Herbal Medicine recently convened an academic seminar with a focus on studies regarding the mechanisms mediating acupuncture efficacy and moxibustion action inspired by the 2021 Nobel Prize in Physiology or Medicine. Specifically, Professor Bailong Xiao introduced the Nobel Prize for research on the mechanically activated Piezo ion channel, evaluating the structure of the Piezo channel and its physiological and pathological functions, and proposed a possible role for the Piezo channel in acupuncture mechanical stimulation. Professor Michael Xi Zhu introduced the discovery of the transient receptor potential (TRP) family, reporting that the therapeutic effects of Chinese medicine and acupuncture may be achieved via the TRP family, and that information regarding associations between the meridian and lymphatic systems may have important research and medical value. In addition, Professor Tianle Xu reviewed the history of ion channel research, particularly the physiological and pharmacological effects of non-classical ion channels (eg, the acid sensing ion channel family) and pointed out that the characterization and neural circuits of acupuncture deqi manipulation are important for elucidating the mechanisms of acupuncture actions. Professor Yongming Li similarly proposed that the 2021 Nobel Prize may open the door to disclosing the histological basis of acupuncture and moxibustion and analyzing the main scientific concerns regarding the clinical translation of acupuncture and moxibustion from basic to translational research. Finally, Professor Yi Guo summarized the study progress of the acupoint microenvironment induced by acupuncture over the course of nearly 30 years and put forward the hypothesis that acupuncture may initiate the physical-chemical coupling network by activating ion channel receptors in acupoints via physical and mechanical stimulation. Therefore, we conclude that a primary achievement of the 2021 Nobel Prize in Physiology or Medicine is in helping interpret how acupuncture and moxibustion adjust homeostasis (ie, by activating mechanical and thermal sensation), which is conducive to validating and promoting the clinical efficacy of acupuncture modalities.

Unlocking the Mystery of the Therapeutic Effects of Chinese Medicine on Cancer.

Over the past decade, the rise of cancer immunotherapy has coincided with a remarkable breakthrough in cancer therapy, which attracted increased interests in public. The scientific community clearly showed that the emergence of immunotherapy is an inevitable outcome of a holistic approach for cancer treatment. It is well established that traditional Chinese medicine (TCM) utilizes the principle of homeostasis and balance to adjust the healthy status of body. TCM treatment toward cancer has a long history, and the diagnosis and treatment of tumors were discussed in the ancient and classical literatures of Chinese medicine, such as the Yellow Emperor’s Inner Canon. Precious heritage has laid the foundation for the innovation and development of cancer treatment with TCM. The modern study indicated that TCM facilitates the treatment of cancer and enhances the survival rate and life expectancy of patients. However, the pharmacological mechanisms underlying these effects are not yet completely understood. In addition, physicians cannot always explain why the TCM treatment is effective and the mechanism of action cannot be explained in scientific terms. Here, we attempted to provide insights into the development of TCM in the treatment and interpret how TCM practitioners treat cancer through six general principles of TCM by using modern scientific language and terms based on newly discovered evidence.

Roles of Gut Microbiota in Pathogenesis of Alzheimer's Disease and Therapeutic Effects of Chinese Medicine.

Alzheimer's disease (AD) is the most common neurodegenerative disease characterized by progressive cognitive impairment. The pathogenesis of AD is complex, and its susceptibility and development process are affected by age, genetic and epigenetic factors. Recent studies confirmed that gut microbiota (GM) might contribute to AD through a variety of pathways including hypothalamic pituitary adrenal axis and inflflammatory and immune processes. CM formula, herbs, and monomer enjoy unique advantages to treat and prevent AD. Hence, the purpose of this review is to outline the roles of GM and its core metabolites in the pathogenesis of AD. Research progress of CMs regarding the mechanisms of how they regulate GM to improve cognitive impairment of AD is also reviewed. The authors tried to explore new therapeutic strategies to AD based on the regulation of GM using CM.

Research Progress in Chinese Medicine Preparations for Promoting Blood Circulation and Removing Blood Stasis for Cirrhotic Patients with Portal Vein Thrombosis Following Splenectomy.

This article presented an overview of the therapeutic effects of Chinese medicine (CM) preparations for promoting blood circulation and removing blood stasis for patients with portal vein thrombosis (PVT) after splenectomy. Based on published clinical researches of CM preparations for PVT after splenectomy in patients with cirrhotic portal hypertension (CPH), this paper evaluated the incidence of PVT, and explored potential active components and mechanisms of CM preparations. Safflower Yellow Injection, Danshen Injection () Danhong Injection (), and Compound Danshen Dropping Pill () achieved good curative effect alone or combined with anticoagulant therapy. In addition, Compound Biejia Ruangan Tablet () and Anluo Huaxian Pill () can also significantly improve the hemodynamic disorders of portal vein system in patients with cirrhosis. Considering the role of CM preparations in ameliorating the incidence of PVT after splenectomy in patients with CPH, we suggested that future research should provide more attention to CM alone or CM combined with anticoagulant for cirrhosis with PVT.

Challenges in Treatment of Primary Sjögren's Syndrome and Opportunities for Chinese Medicine.

Primary Sjögren's syndrome is a chronic autoimmune disease that can lead to systemic manifestations. At present, immunomodulatory agents have not shown good efficacy, many patients in China seek Chinese medicine treatment. Chinese medicine can comprehensively improve the symptoms of patients through Chinese pattern diagnosis and individualized treatment. Fundamental researches are providing scientific bases for the therapeutic effect of Chinese medicine. Professional Chinese medicine treatment can be integrated into the conventional management of primary Sjögren's syndrome.

Effects of Chinese medicine on patients with acute exacerbations of COPD: study protocol for a randomized controlled trial

BackgroundThe incidence, mortality, and prevalence of chronic obstructive pulmonary disease (COPD) are high in China. Acute exacerbations of COPD (AECOPD) are important events in the management of COPD because they negatively impact health status, rates of hospitalization and readmission, and disease progression. AECOPD have been effectively treated with Chinese medicine for a long time. The aim of this proposed trial is to assess the therapeutic effect of Chinese medicine (CM) on AECOPD.Methods/designThis proposed study is a multicenter, double-blind, parallel-group randomized controlled trial (RCT). We will randomly assign 378 participants with AECOPD into two groups in a 1:1 ratio. On the basis of health education and conventional treatment, the intervention group will be treated with CM, and the control group is given CM placebo according to CM syndrome. Patients are randomized to either receive CM or placebo, 10 g/packet, twice daily. The double-blind treatment lasts for 2 weeks and is followed up for 4 weeks. The main outcome is the COPD Assessment Test; secondary outcomes are treatment failure rate, treatment success rate, length of hospital stay, AECOPD readmission rate, intubation rate, mortality, dyspnea, the 36-item Short Form Health Survey, and the COPD patient-reported outcome scale. We will document these outcomes faithfully at the beginning of the study, 2 weeks after treatment, and at the 4 weeks follow-up.DiscussionThis high-quality RCT with strict methodology and few design deficits will help to prove the effectiveness of CM for AECOPD. We hope this trial will provide useful evidence for developing a therapeutic schedule with CM for patients with AECOPD.Trial registrationClinicalTrials.gov, NCT03428412.

Efficacy and indication optimization of Chinese medicine (Tiao-Chang Ke-Min granules) for diarrhea-predominant irritable bowel syndrome: study protocol for a randomized controlled trial

BackgroundIrritable bowel syndrome (IBS) is a chronic, recurring condition, prevalent in the general population. Current medication treatments usually leave patients undertreated. Nowadays, Chinese medicine (CM) is being considered as a promising treatment approach for IBS. However, due to methodological limitations, there is no strong evidence to support CM. Although IBS relapses are common, the relapse assessment has always been neglected in CM study designs. Meanwhile, in clinical practice and studies, it has been found that certain CM formulas can only benefit certain kinds of patients. Discovering what population and illness characteristics likely respond to outcomes may help improve the effectiveness of CM. The aims of this study are to evaluate the efficacy and safety of Tiao-Chang Ke-Min (TCKM) granules for IBS, especially in reducing IBS symptoms’ relapse, by a high-quality randomized controlled trial and then to optimize the indication of the TCKM granules.Methods/designThis is a parallel-group, randomized, double-blind, placebo-controlled trial embedded with outcome predictive factors. Eligible patients with diarrhea-predominant IBS will be randomized into either a TCKM granule group or a placebo group. Patients from both groups will receive health education. The treatment duration is 4 weeks and the follow-up is 12 weeks. The primary outcome is global improvement measured with adequate relief (AR). The second outcome measures include time until relief, time until first relapse, total relapse times, long-term effectiveness, individual symptoms, IBS-Symptom Severity Score (IBS-SSS), IBS-Quality of Life Questionnaire (IBS-QOL), and Hospital Anxiety and Depression Scale (HADS). Predictive factors associated with patient and illness characteristics have been widely collected. These factors will be embedded in this trial for further identification.DiscussionThis trial may provide high-quality evidence on the efficacy and safety of TCKM granules for IBS and a more accurate indication. Importantly, this trial will provide a new research method for improving the therapeutic effects of CM for clinicians and researchers. To address IBS relapse assessment, a series of special definitions of relapse incidents has been made for this trial.Trial registrationChinese Clinical Trial Registry, ID: ChiCTR-IOR-17010600.

Application of Response Evaluation Criteria of Traditional Chinese Medicine for Solid Tumor in advanced non-small cell lung cancer.

To evaluate the objectivity and comprehensiveness of Response Evaluation Criteria of Traditional Chinese Medicine for Solid Tumor (Draft, REC-TCM-ST) in application of Chinese medicine therapeutic effect in patients with advanced non-small cell lung cancer (NSCLC). A retrospective clinical research was used in 104 NSCLC patients in stages of III-IV, 53 cases were in Chinese medicine (CM) group and 51 cases were in Western medicine (WM) group. The therapeutic effect of the two groups was evaluated with both REC-TCM-ST and Response Evaluation Criteria in Solid Tumor (RECIST). Kaplan-Meier method was used to analyze the survival time. Kappa test method was used to test the consistency of the two kinds of evaluation results. According to REC-TCM-ST, the effective rate on relieving tumor mass in the CM group was significantly lower than that in the WM group (P<0.05), but there was no significant difference in tumor-mass stable rate (P>0.05); the symptom of weakness in the CM group was improved significantly, indicating better therapeutic effect than that in the WM group (P<0.01). Karnofsky score in the CM group was significantly better than that in the WM group (P<0.01). In terms of survival conditions, the median survival time and the survival rate of 6 months, 1 year and 2 years of the CM group were higher than the WM group. The total effective rate was 9.62%, and the total stable rate was 72.12% for 104 cases according to RECIST; while the total effective rate was 34.62%, and the total stable rate was 84.62% according to REC-TCM-ST, thus there were significant differences between the results of the two criteria (P<0.01), and there was also some consistency between them, but not satisfactory. REC-TCM-ST was used to evaluate the therapeutic effect of CM in the treatment of advanced NSCLC, which shows that its evaluation results can better reflect the advantages and disadvantages of CM, and the effectiveness of CM is more objective and comprehensive than RECIST, so REC-TCM-ST is worthy of further improvement and clinical expansion.

Kidney tissue targeted metabolic profiling of glucocorticoid‐induced osteoporosis and the proposed therapeutic effects of Rhizoma Drynariae studied using UHPLC/MS/MS

Traditional Chinese medicine and modern science have indicated that there is a close relationship between bone and kidney. In light of this, this project was designed to study the metabolic profiling by UHPLC/MS/MS of glucocorticoid-induced osteoporosis in kidney tissue and the possible therapeutic effects of Rhizoma Drynariae (RD), a classic traditional Chinese medicine, in improving the kidney function and strengthening bone. Twenty-one Wistar rats were divided into three groups: control group (rats before prednisolone inducing), a model group (prednisolone-induced group) and a treatment group (prednisolone-induced rats that were then administered RD ethanol extracts). By using pattern recognition analysis, a significant change in the metabolic profile of kidney tissue samples was observed in the model group and restoration of the profile was observed after the administration of RD ethanol extracts. Some significantly changed biomarkers related to osteoporosis such as sphingolipids (C16 dihydrosphingosine, C18 dihydrosphingosine, C18 phytosphingosine, C20 phytosphingosine), lysophosphatidycholines (C16:0 LPC, C18:0 LPC) and phenylalanine were identified. As a complement to the metabolic profiling of RD in plasma, these biomarkers suggest that kidney damage, cell cytotoxicity and apoptosis exist in osteoporosis rats, which is helpful in further understanding the underlying process of glucocorticoid-induced osetoporosis and the suggested therapeutic effects of RD. The method shows that tissue target metabonomics might provide a powerful tool to further understand the process of disease and the mechanism of therapeutic effect of Chinese medicines.

Metabolomics research on time-selected combination of Liuwei Dihuang and Jinkui Shenqi pills in treating kidney deficiency and aging by chemometric methods

Jinkui Shenqi pill (JKSQ) and Liuwei Dihuang (LWDH) pills are ancient traditional Chinese medicines (TCMs), which are usually used for the treatment of kidney deficiency for thousands of years in China. Time-selected combination of LWDH and JKSQ pills in treating kidney deficiency and aging is one of the features of traditional Chinese medicines (TCMs). However, the molecular mechanisms of time-selected combination remain unclear. In this work, UHPLC–QTOF/MS based metabolomics research was conducted to evaluate the therapeutic effect of LWDH, JKSQ pills and their combinations on kidney deficiency in Sprague–Dawley rats induced by d-galactose and Dexamethasone. Based on peak areas of serum extracts, analysis of variance (ANOVA) and graphical index of separation (GIOS) were employed to select the significant variables for kidney deficiency and aging and principal component projection (PCP) was subsequently applied to evaluate the influence of drugs on endogenous metabolites. 10 endogenous metabolites from 22 important ions were identified via database search. The score plot of PCA shows that nourishing Yang–nourishing Yin group shows the strongest rehabilitation for metabolic disorder induced by kidney deficiency and aging, which is consistent with the classic theories of traditional Chinese medicine. Moreover, metabolic pathway function analysis indicates that kidney deficiency and aging might possess closed relationships with lipid metabolism and energy metabolism. In this work, the change trends of potential biomarkers after administration provide molecular evidence for combined administration of Jinkui Shenqi pill in the morning and Liuwei Dihuang pill at night for the patients with kidney deficiency. The method proposed in this study may provide inspiration for evaluation of the therapeutic effect of Chinese medicines by comparing the rehabilitation of potential biomarkers.

Treatment of acquired immunodeficiency syndrome with chinese medicine in China: Opportunity, advancement and challenges

Chinese medicine (CM) has been used in the treatment of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) for 30 years and the demonstrated therapeutic effects of CM, such as reducing plasma HIV viral load, increasing CD4(+)T cell counts, promoting immunity reconstitution, ameliorating symptoms and signs, improving the health related quality of life (HRQOL) and counteracting against the effects of anti-retroviral drugs, were summarized and reviewed in this article. The authors point out that it had been a good opportunity to use CM for the treatment of HIV infection and AIDS in the past and also there are huge challenges ahead for CM research and clinicians to discover more effective CM and its underlying mechanisms for treatment of AIDS.

Evidence-Based Medicine: Step 3—Critical Appraisal of Therapeutic Literature

Identification and quantification of 13 components in Angelica sinensis (Danggui) by gas chromatography–mass spectrometry coupled with pressurized liquid extraction

Angelica sinensis (Danggui in Chinese), a well-known traditional Chinese medicine, is also used as a health food product for women's care in Europe and America. Therefore, the demand for Danggui is enormous throughout the world. Due to the shortage of Angelica sinensis, Angelica acutiloba and Angelica gigas are commonly used as the substitutes of Danggui in the market of southeast Asia. However, the three common Angelica roots showed variation in their genetic and chemical composition. Up to date, it is thought that ferulic acid, ligustilide and other phthalides such as butylidenephthalide are the biologically active components of Danggui. In this paper, the contents of 13 compounds including ferulic acid, Z-ligustilide, E-ligustilide, Z-butylidenephthalide, E-butylidenephthalide, 3-butylphthalide, 3-butylidene-4-hydroxyphthalide, senkyunolide A, 6,7-epoxyligustilide, senkyunolide F, senkyunolide H, senkyunolide I, and 6,7-dihydroxyligustilide were determined or estimated by using gas chromatography–mass spectrometry (GC–MS) coupled with pressurized liquid extraction (PLE). The results showed that GC–MS coupled with PLE offered a simple, rapid and high sensitive method to analysis of components in Angelica root. And the contents of investigated compounds in Angelica sinensis, Angelica acutiloba and Angelica gigas, which are used as Danggui in China, Japan and Korea, respectively, were highly variant. It is thought that interaction of multiple chemical compounds contributes to the therapeutic effects of Chinese medicines. However, the overall clinical efficacy of these different Danggui has not been determined. Therefore, comparison of chemical components and pharmacological activities of different Angelica root is helpful to elucidate the mechanism of therapeutic effects of Danggui.
