Star Anise (Illicium verum Hook. f.): Dual Therapeutic and Nutritional Potential in Food and Medicine

Star anise (Illicium verum Hook. f., SA) is a well-known culinary seasoning in China and Vietnam. Actually, SA also has been widely used as a traditional Chinese medicine in China with a long history. Phytochemical analysis has revealed that SA contains a high concentration of essential oils, phenols, flavonoids, and other bioactive compounds that contribute to its diverse pharmacological properties. These properties include anti-bacterial, anti-inflammatory and analgesic, anti-oxidation, anti-viral, anti-cancer, anti-diabetes, anti-diarrheal and promoting hair growth. Various preclinical studies have shown that SA extracts and their active constituents may have potential therapeutic applications in preventing and treating various diseases. However, a comprehensive report on the relationship between the active ingredient, biological activity and food characteristics of SA is rare. The medicinal value of SA has not been well valued and developed. This review provides an overview of the botanical chemistry and pharmacological properties of SA, as well as its potential innovative applications in food and personal care products, aiming to provide theoretical support for its further development and utilization.

Emodin regulated lactate metabolism by inhibiting MCT1 to delay non-small cell lung cancer progression.

Lung cancer is one of the most common malignant tumors in the world, with high incidence rate and mortality. Monocarboxylate transporter (MCT) 1 has been found to be widely expressed in various tumors and plays a crucial role in regulating energy metabolism. Emodin, as an important traditional Chinese medicine in China, has been reported to inhibit the progression of lung cancer. However, its potential mechanism has not been fully elucidated. The effects of emodin and MCT1 inhibitor AZD3965 on the proliferation, migration, and invasion of lung cancer cells were detected using cell counting kit-8 (CCK-8) assay, wound-healing assay, and transwell small chamber assay. The content of glucose, lactate, and pyruvate in the cell culture medium was detected using a glucose, lactate, and pyruvate detection kit, and also detected protein expression using western blotting. In addition, to investigate the effects of emodin and AZD3965 on lung cancer in vivo, we constructed nude mice subcutaneous transplant tumor model by subcutaneous injection of lung cancer cells. The results showed that emodin and AZD3965 could inhibit the proliferation, migration, and invasion of lung cancer cells. At the same time, they could inhibit the expression of MCT1 in lung cancer cells and promote the release of lactate, but did not affect the content of glucose and pyruvate. In vivo experiments had shown that emodin and AZD3965 could effectively inhibit the growth of lung cancer and inhibit the expression of MCT1. All in all, our data suggested that emodin inhibited the proliferation, migration, and invasion of lung cancer cells, possibly by inhibiting MCT1, providing important theoretical basis for elucidating the mechanism of emodin in treating lung cancer.

Effect of prophylactic infusion of norepinephrine on the prevention of hypotension during vertebroplasty: a randomized clinical trial

BackgroundTransient hypotension is a common occurrence during the implantation of bone cement. This placebo-controlled randomized clinical trial study investigated the effect of prophylactic infusion of norepinephrine on the incidence of hypotension in senior patients who underwent vertebroplasty.MethodsThe trial recruited patients who were greater than or equal to 65 years of age, had an American Society of Anesthesiologist physical status classification of I to III, and underwent vertebroplasty from August 2020 to August 2021 at the Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine in China. The patients were randomly grouped according to whether they received either a norepinephrine infusion of 0.05 µg/kg/min or an equivalent volume of saline 10 min before implantation of bone cement. Intraoperative hemodynamics were monitored continuously by the MostCare system at the following 7 time points: 10 min before implantation of bone cement and immediately, 30 s, 1, 3, 5, and 10 min after implantation of bone cement. We also recorded the number of hypotensive episodes and the total number of vasopressors after implantation of bone cement. Multivariable logistic regression was used to assess the risk factors associated with hypotension after implantation of bone cement.ResultsA total of 63 patients were randomized to the control group (n = 31; median [IQR] age, 74 [69–79] years) and the norepinephrine group (n = 32; median [IQR] age, 75 [71–79] years). The incidence of hypotension in the norepinephrine group was significantly lower than that in the control group after implantation of bone cement (12.5% vs. 45.2%; relative risk [RR], 3.61 [95% CI, 1.13–15.07]; P = 0.005). Moreover, the median (IQR) number of hypotensive episodes (0 [0–0] vs. 0 [0–2]; P = 0.005) and the total number of vasopressors (0 [0–0] vs. 0 [0–1]; P = 0.004) in the norepinephrine group were significantly lower than those in the control group. Furthermore, compared with the baseline, the MAP significantly decreased at 1 min (P = 0.007) and 3 min (P < 0.001) after bone cement implantation in the control group. However, the MAP at 3 min in the norepinephrine group was significantly higher than that in the control group (P < 0.001). The incidence of complications was not different between the groups. In multivariable logistic regression, the FRAIL score (OR, 2.29; 95% CI, 1.21–4.31) was identified as a risk factor associated with hypotension.ConclusionProphylactic infusion of norepinephrine before bone cement implantation can stabilize hemodynamics and reduce the incidence of hypotension after implantation of bone cement.

First Report of Didymella pomorum Causing Leaf Blight on Angelica sinensis in China.

Angelica sinensis (Oliv.) Diels, is a perennial herbaceous plant of the Umbelliferae family. It has a long history of cultivation and is highly valued as a traditional Chinese medicine in China (Zhang et al. 2012). In September 2023, leaf blight on A. sinensis with an average disease incidence of 56% was recorded in an approximately 6.7-ha production field in Lijiang, Yunnan province, China (26.8215°N, 100.2369°E). At first, small, chlorotic lesions appeared on the leaves. They subsequently increased in density and gradually merged, causing leaves to yellow and wither. Ultimately the blight casused death of the entire foliage. In order to identify the causal agent, cross-sectional segments (5×5 mm2) were cut from the edge of leaf lesions, surface disinfected with a 1% sodium hypochlorite solution for 3 min and rinsed three times with sterile distilled water. They were subsequently placed on potato dextrose agar (PDA) plates and incubated for 3 days under a 12-h photoperiod at 28℃. A total of ten isolates with similar morphological characteristics were obtained by single spore isolation. After 10 days of incubation on PDA, the colony morphology of these isolates was characterized by a brownish central area with a white edge. Aged colonies became wrinkled in the center of the colony. Conidia (n = 30) were elliptical and brown, with a size range of 4.11 to 6.55 μm (average 5.37±0.74 μm) × 3.17 to 4.62 μm (average 3.92±0.43 μm). Chlamydospores (n = 30) formed chains in series, spherical or elliptical in shape, ranging from yellow-brown to dark brown, with a size range of 12.30 to 13.70 μm (average 12.98±0.46 μm) × 4.20 to 5.30 μm (average 4.63±0.26 μm). The nuclear ribosomal internal transcribed spacer region (ITS), the second largest subunit of RNA polymerase II (RPB2), and the 28S nuclear ribosomal large subunit rRNA (LSU) region of two isolates were amplified with the primer pairs ITS1/ITS4 (White et al. 1990), fRPB2-5F/fRPB2-7cR (Liu et al. 1999), and LR0R/LR5 (Schoch et al. 2012), respectively. These amplicons were sequenced bidirectionally and assembled. The two isolates produced the same nucleotide sequences, and the sequences of a representative isolate (AsDp1) were deposited in GenBank. BLASTn analyses showed that the ITS (PP510616), RPB2 (PP526010), and LSU (PP550143) sequences of isolate AsDp1 were 100%, 99.66%, and 100% identical with those of Didymella pomorum ex-type isolate CBS 354.52 (MH857081, KT389616, and MH868616), respectively. A phylogenetic tree was constructed based on the ITS, RPB2, and LSU concatenated nucleotide sequences using the maximum likelihood method in MEGAX. Isolate AsDp1 was clustered with four D. pomorum isolates. According to the morphological and nucleotide sequences analyses, isolate AsDp1 was identified as D. pomorum (Chen et al. 2015). To determine pathogenicity, 1-year-old A. sinensis plants (approximately 20 cm tall) grown in 7-liter pots filled with sterilized field soil were sprayed until runoff with a 1×106 conidia/ml suspension of isolate AsDp1 onto the foliage, while control plants were sprayed with sterile water. All plants were cultivated under a 12-h photoperiod at 25℃. The pathogenicity tests were performed in triplicate with ten plants in each treatment. After fifteen days, numerous chlorotic lesions appeared on the leaves of all inoculated plants. The symptoms were similar to those found on naturally infected plants in the field, while the control plants remained asymptomatic. Subsequently, D. pomorum was reisolated from the diseased leaves, and the identity was confirmed based on its ITS sequence and morphological characteristics. D. pomorum causing stem canker on Rosa spp. was reported in Canada (Ilyukhin 2022). To our knowledge, this is the first report of D. pomorum causing leaf blight on A. sinensis in China. This etiological finding will potentially pave the way for the development of control strategies of this disease.

Elucidating the interaction of rhizosphere microorganisms and environmental factors influencing the quality of Polygonatum kingianum Coll. et Hemsl.

Polygonatum kingianum Collett & Hemsl., is one of the most important traditional Chinese medicines in China. The purpose of this study is to investigate the relationship between herb quality and microbial-soil variables, while also examining the composition and structure of the rhizosphere microbial community in Polygonatum kingianum, the ultimate goal is to provide a scientific approach to enhancing the quality of P. kingianum. Illumina NovaSeq technology unlocks comprehensive genetic variation and biological functionality through high-throughput sequencing. And in this study it was used to analyze the rhizosphere microbial communities in the soils of five P. kingianum planting areas. Conventional techniques were used to measure the organic elements, pH, and organic matter content. The active ingredient content of P. kingianum was identified by High Performance Liquid Chromatography (HPLC) and Colorimetry. A total of 12,715 bacterial and 5487 fungal Operational Taxonomic Units (OTU) were obtained and taxonomically categorized into 81 and 7 different phyla. Proteobacteria, Bacteroidetes, and Acidobacteriae were the dominant bacterial phyla Ascomycota and Basidiomycota were the dominat fungal phyla. The key predictors for bacterial community structure included hydrolysable nitrogen and available potassium, while for altering fungal community structure, soil organic carbon content (OCC), total nitrogen content (TNC), and total potassium content (TPOC) were the main influencing factors. Bryobacter and Candidatus Solibacter may indirectly increase the polysaccharide content of P. kingianum, and can be developed as potential Plant Growth Promoting Rhizobacteria (PGPR). This study has confirmed the differences in the soil and microorganisms of different origins of P. kingianum, and their close association with its active ingredients. And it also broadens the idea of studying the link between plants and microorganisms.

Characterization and phylogenetic analysis of the complete chloroplast genome of Carpesium lipskyi (Asteraceae, Inuleae)

The species of Carpesium lipskyi C.Winkl. 1998 is an important traditional Chinese medicine in China. In this study, the complete chloroplast (cp) genome of C. lipskyi was determined and analyzed. The result showed that the complete cp genome of C. lipskyi was 151,244 bp in length, consisting of a large single-copy (LSC) region of 82,908 bp, a small single-copy (SSC) region of 18,430 bp, and a pair of inverted repeats (IRs) of 24,953 bp. The overall GC content of the C. lipskyi is 37.68%. The species of C. lipskyi possessed 127 genes, including 83 protein-coding genes, 36 transfer RNA genes, and eight ribosomal RNA genes. The present study found that Inula is sister groups with the closest genetic relationship. The obtained knowledge could provide useful information for future phylogenetic, taxonomic, and evolutionary studies on Inuleae.

Acupuncture and Sleep Quality Among Patients With Parkinson Disease

Poor sleep quality greatly impairs quality of life and accelerates deterioration in patients with Parkinson disease (PD), but current remedies remain limited. Acupuncture, used as an adjunctive therapy with anti-Parkinson medications, has shown positive effects in patients with PD. However, high-quality clinical evidence to support the effectiveness of acupuncture for patients with PD and poor sleep quality is lacking. To assess the safety and efficacy of real acupuncture (RA) vs sham acupuncture (SA) as an adjunctive therapy for patients with PD who have poor sleep quality. This single-center randomized clinical trial was performed at The First Affiliated Hospital of Guangzhou University of Chinese Medicine in China from February 18, 2022, to February 18, 2023. Patients with PD and sleep complaints were recruited and randomized (1:1) to receive RA or SA treatment for 4 weeks. Data analysis was performed from April 12 to August 17, 2023. Treatment with RA or SA for 4 weeks. The main outcome was the change in Parkinson Disease Sleep Scale (PDSS) scores measured at baseline, after 4 weeks of treatment, and at 8 weeks of follow-up. Of the 83 participants enrolled, 78 (94.0%) completed the intervention and were included in the analysis. Their mean (SD) age was 64.1 (7.9) years; 41 (52.6%) were men and 37 (47.4%) were women. A significant increase in PDSS scores from baseline was observed for both the RA group (29.65 [95% CI, 24.65-34.65]; P < .001) and the SA group (10.47 [95% CI, 5.35-15.60]; P < .001). Compared with the SA group, the RA group had a significant increase in PDSS scores after 4 weeks of treatment (19.75 [95% CI, 11.02-28.49]; P < .001) and at 8 weeks of follow-up (20.24 [95% CI, 11.51-28.98]; P < .001). In this randomized clinical trial, acupuncture proved beneficial in improving sleep quality and quality of life among patients with PD. These findings suggest that the therapeutic effects of acupuncture could continue for up to 4 weeks. Chinese Clinical Trial Registry Identifier: ChiCTR2200060655.

Syndrome Differentiation and Mechanism Exploration of “Tongguan Liqiao” Acupuncture Method for Treating Poststroke Dysphagia

Abstract“Tongguan Liqiao” acupuncture method established by Xuemin Shi, a master of traditional Chinese medicine in China and academician of the Chinese Academy of Engineering, derives from the famous “Xing Nao Kai Qiao” therapy (activating the brain and opening the orifices) acupuncture method. It fundamentally takes “adjusting the spirit” as the root of selecting acupoints based on syndrome differentiation. Neiguan (PC 6), Renzhong (DU 26), and Sanyinjiao (SP 6) are selected as the main acupoints to adjust the spirit and revive the brain, nourish the liver and kidney, which treats the root cause. Acupoints such as Lianquan (RN 23), Yifeng (SJ 17), Wangu (GB 12), and Fengchi (GB 20) in the neck region are selected for “unblocking orifices,” which relieves the symptoms. This acupuncture method features deep needling, which aligns with modern swallowing function anatomy. The method can improve the function of poststroke dysphagia by enhancing cerebral blood supply and metabolism and promoting neural functional remodeling.

The safety and efficacy of Sotn ureteroscopy for renal and upper ureteral calculi: a prospective multicenter randomized controlled trial.

Sotn ureteroscopy is a new lithotripsy procedure developed on the basis of ureteroscopy and includes a rigid ureteral access sheath, standard mirror, lithotripsy mirror, and Sotn perfusion aspirator. Thus, we performed a prospective multicenter randomized controlled trial comparing the safety and efficacy of Sotn ureteroscopy in the treatment of renal and upper ureteral calculi. In this study, 224 patients with renal and upper ureteral calculi were randomly divided equally into study and control groups from March 2018 to March 2022. All the patients were approved by the hospital ethics committee (proof number: ZF-2018-164-01 and ZF-2018-165-01) of the Second Affiliate Hospital of Guangzhou University of Chinese Medicine in China. The primary outcome was stone-free rate (SFR) assessed by computed tomography on the 1st day and month after treatment and operation duration. The secondary outcome was postoperative complication rate. In total, for upper ureteral calculi, the SFR of 1 day after operation of the Sotn ureteroscopy group was significantly higher than the rigid ureteroscopy group (83.6% vs. 60%, P=0.006). Moreover, operative time (33.7±1.80 vs. 52.9±2.73 min, P<0.005) of the Sotn ureteroscopy group was significantly lower than the rigid ureteroscopy group. Additionally, the SFR of 1 day after operation and operative time for the study group (Sotn ureteroscopy combined with flexible ureteroscopy) and the control group (flexible ureteroscopy alone) were 63.2% and 36.8% (P=0.005), 65.6±4.06 and 80.3±4.91 (P=0.023), respectively. However, there were no significant differences in the SFR of 1 month after operation, success rate of ureteral access sheath placement, and postoperative complications between the two groups (P>0.05). In subgroups with stone diameters ≥1.5 cm and stone CT values ≥1000 Hounsfield units, Sotn ureteroscopy showed more advantages in terms of the SFR of 1 day after operation. Importantly, complications such as ureteral injury, sepsis, fever, and severe hematuria were not statistically different between the two groups (P>0.05). For renal and upper ureteral calculi, Sotn ureteroscopy has the advantage of a higher SFR of 1 day after the operation and a shorter operative time, suggesting that the Sotn ureteroscopy may have further potential applications in clinics.

First Report of Pseudocercospora oenotherae Causing Leaf Spot in Rhinacanthus nasutus in China

Rhinacanthus nasutus (L.) Kurz is a traditional Chinese medicine in China. In August 2022, leaf spots were observed on R. nasutus in a Chinese herbal garden in Zhanjiang, Guangdong Province, China (21°17′30″N, 110°18′25″E). Disease incidence was 90% (n = 100 investigated plants from about 800 plants). The yellow spots were round, gray in the center and scattered on the leaves. The coalescence of the individual spot eventually led to leaf wilt. Ten symptomatic leaves from 10 plants were sampled. The margins of the samples were cut into 2 mm × 2 mm pieces. The tissue surface was disinfected with 75% ethanol for 30 s and 2% sodium hypochlorite for 60 s. Thereafter, the samples were rinsed three times in sterile water, placed on potato dextrose agar (PDA), and incubated at 28 °C. Pure cultures were obtained by transferring hyphal tips to new PDA plates. Twenty-eight isolates were obtained (isolation frequency = 28/4 × 10 = 70%). Three representative single-spore isolates (RNPO-1, RNPO-2, and RNPO-3) by a single-spore isolation method (Fang. 1998) were used for further study. The colonies of isolates on PDA were olive green in 7 days at 28 °C. Conidiogenous cells were unbranched, geniculate–sinuous, tapered toward the apex, and 10 to 20 × 3 μm (n = 20). Conidia were solitary, smooth, straight or curved, pale brown, 3 to 8-septate, apex acute, base truncate, and 50.5 to 88.5 × 2.0 to 3.5 μm (n = 50). For molecular identification, the colony PCR method with Taq DNA polymerase and MightyAmp DNA Polymerase (Lu et al. 2012) was used to amplify the internal transcribed spacer (ITS), translation elongation factor 1-α gene (TEF1), actin (ACT) , and RNA polymerase II second largest subunit (RPB2) loci of the isolates using primer pairs ITS1/ITS4, EF1/EF2, ACT-512F/ACT-783R, and RPB2-7CF/fRPB2-11aR, respectively (O’Donnell et al. 1998; O’Donnell et al. 2010). Their sequences were deposited in GenBank under nos. OP963568 to OP963570 (ITS), OP998376 to OP998378 (TEF1), OP998373 to OP998375 (ACT), and OP998379 to OP998381 (RPB2). By using the Maximum Likelihood method, a phylogenetic tree was generated on the basis of the concatenated data from the sequences of ITS, TEF1, ACT, and RPB2 that clustered the isolates with P. oenotherae (the type strain CBS 131920). The fungus was thus identified as P. oenotherae basing on these morphological and molecular characteristics (Guo and Liu. 1992; Kirschner. 2015). Pathogenicity testing was performed in a greenhouse with 80% relative humidity at 28 °C to 30 °C. Healthy plants of R. nasutus were grown in pots, with one plant in each pot. Sterile cotton balls were immersed in the spore suspension (1 × 105 per mL) of the isolates for about 15 s before they were adhered to the leaves for 3 days. Each isolate was inoculated with three plants (2 month old), and each plant was inoculated with five leaves. Sterile distilled water was as the control and same treatment. The test was performed three times. Symptom were found on the inoculated plants after 2 weeks with the disease incidence 100%, whereas the control plants remained healthy. The fungus was re-isolated from the infected leaves and confirmed as the same isolates by morphological and ITS analyses. No pathogen was isolated from the control plants. P. oenotherae caused leaf spot on Oenothera biennis L. (Guo and Liu. 1992). To the best of our knowledge, this is the first report that R. nasutus is the new host of P. oenotherae (Crous et al. 2013). Thus, this work provides an important reference for the control of this disease in the future.

The Textual Relationship between Zhongguo Yixue Dacidian and YiJi ZhiJin

Zhongguo Yixue Dacidian(The Dictionary of Chinese Medicine,«») is the first comprehensive dictionary of traditional Chinese medicine in China. The dictionary, edited by Xie Guan()and compiled for several years by the teachers and students of Shanghai Special School of Traditional Chinese Medicine, was first published by The Commercial Press in 1921. In 1919, Lu Simian() joined The Commercial Press to assist Xie Guan who is his old friend in compiling the contents on medical books for the dictionary . In the same year, Lu Simian wrote a book called YiJi ZhiJin(«»). Recently, some scholars believe that Xie Guan disassembled YiJi ZhiJin and compiled it into Zhongguo Yixue Dacidian. Through a comparative study of these two, it can be seen that YiJi ZhiJin and Zhongguo Yixue Dacidian do use homologous materials in the interpretation of some medical books, but YiJi ZhiJin as a whole is not compiled into Zhongguo Yixue Dacidian, and the idea of there is a plagiarism relationship between them is incorrect.

Evaluation of the clinical efficacy of Ru'ai Shuhou recipe for the prevention of lung metastases from breast cancer: a retrospective study based on propensity score matching.

Breast cancer lung metastasis occurs at a high rate and at an early stage, and is the leading cause of death in breast cancer patients. The aim of this study was to investigate the effect of Ru'ai Shuhou Recipe (RSR) intervention on the occurrence of recurrent metastases, especially lung metastases, in postoperative patients with breast cancer. A retrospective cohort study was implemented at Shuguang Hospital of Shanghai University of Traditional Chinese Medicine in China between January 2014 to January 2019. Female patients were included according to the propensity score matching (PSM) method and balanced on the basis of general and clinical information such as age, body mass index, neo-adjuvant therapy, and surgical approach. Patients with pathological diagnosis of breast cancer were included in this study. Breast cancer patients were divided into exposed and non-exposed groups according to whether they took RSR-based botanical drugs after surgery. Kaplan-Meier survival analysis and Cox survival analysis to explore the relationship between RSR and 5-year disease-free survival and incidence of lung metastases in breast cancer patients after surgery. 360 female patients were assessed and 190 patients were included in the study after PSM (95 in each of the exposed and non-exposed groups). Of the 190 patients after PSM, 55.79% were over 50years of age. The mean follow-up time was 60.55 ± 14.82months in the exposed group and 57.12 ± 16.37months in the non-exposed group. There was no significant baseline characteristics difference between two groups. Kaplan-Meier analysis showed that the 5-year incidence of lung metastases was significantly lower in the exposed group, and the disease-free survival of patients was significantly longer. Cox univariate and multivariate analysis showed that neoadjuvant chemotherapy and lymph node metastasis were independent risk factors for the development of breast cancer lung metastasis, with risk ratios of 17.188 and 5.812, while RSR treatment was an independent protective factor against the development of breast cancer lung metastasis, with a risk ratio of 0.290. Standard biomedical treatment combined with RSR intervention can better prevent breast cancer recurrence and metastasis, reduce the incidence of lung metastasis in patients, and improve long-term prognosis.

The analysis of factors affecting medication adherence in patients with myasthenia gravis: a cross-sectional study.

Clinically, patients with myasthenia gravis are generally treated with drugs to improve their physical condition, and poor medication adherence can hinder their recovery. Many studies have shown the importance of medication adherence for effective treatment. Various factors may affect a patient's medication adherence; however, studies concerning medication adherence in patients with myasthenia gravis are rare. This study aimed to identify the factors related to medication adherence in patients with myasthenia gravis, and determine the possibility of predicting medication adherence. This cross-sectional observational study was conducted among inpatients and outpatients with myasthenia gravis of the First Affiliated Hospital of Guangzhou University of Chinese Medicine in China. Data on patient demographics, disease-related characteristics, and medical treatment were collected. We evaluated medication adherence of the patients using the Morisky Medication Adherence Scale-8, Beliefs about Medicines Questionnaire, and the Self-efficacy for Appropriate Medication Use Scale. We distributed 200 questionnaires and finally retrieved 198 valid questionnaires. A total of 139 (70.2%) women participated in this study, and 81 (40.9%) among the 198 participants were aged 40-59 years. In total, 103 (52.0%) participants exhibited bad adherence to pharmacological treatment, and factors such as taking medication irregularly [odds ratio (OR) = 0.242, 95% CI = 0.093-0.627], the necessity of taking medicine (OR = 1.286, 95% CI = 1.142-1.449), the concerns of taking medicine (OR = 0.890, 95% CI = 0.801-0.988), and the self-efficacy for taking medications under difficult circumstances (OR = 1.194, 95% CI = 1.026-1.389) had statistically significant impacts on medication adherence. Our study shows that taking medication irregularly and concerns of taking medicine are the risk factors for medication adherence. Meanwhile, the necessity of talking medicine and self-efficacy for taking medications under difficult circumstances are the protective factors for medication adherence. Our findings can help medical staff to enhance patients' medication adherence by informing patients necessary medical knowledge, emphasizing the necessity for medication, relieving patients' concerns regarding medication, and improving the self-efficacy for taking medications under difficult circumstances.

Ginsenoside Rg1 modulates PI3K/AKT pathway for enhanced osteogenesis via GPER

BackgroundOsteoporosis is a systemic skeletal disorder characterized by decreased bone density and the degradation of bone tissue microarchitecture. Ginsenoside Rg1, derived from Panax ginseng, has been a part of traditional Chinese medicine in China for centuries, particularly for treating osteoporosis. However, there remains limited research on the osteogenic potential of Rg1 within the glucocorticoid-induced osteoporosis (GIOP) model and its specific mechanisms. PurposeThe primary objective of this study is to investigate the osteogenic potential of Rg1 within the GIOP model and explore the signaling pathways associated with its in vivo and in vitro effects. MethodsCell proliferation, differentiation and mineralization were evaluated by the Cell counting kit 8(CCK8) assay, alkaline phosphatase (ALP) test and Alizarin Red S staining, respectively. The qPCR technique was used to determine the relative expression of mRNA and the western blot was used to determine the relative expression of protein. In vivo experiments, spinal vertebrae staining in zebrafish larvae was accomplished by alizarin red S staining. ResultsZebrafish larvae's hatching, survival, malformation, and heart rate were unaffected by 50 μM of Rg1 in vivo, while the MEC3T3-E1 cell line's proliferation was unaffected by 50 μM of Rg1 in vitro. Meanwhile, Rg1 was shown to improve osteogenic differentiation or bone formation as well as the level of mRNA expression of osteogenic markers in vivo and in vitro. Treatment with Rg1 significantly increased the expression of G protein-coupled estrogen receptor (GPER) and pAKT. In addition, the GPER inhibitor G15 could significantly reduce the mRNA and protein expression levels of GPER and phosphorylated AKT, LY294002, a PI3K/AKT pathway inhibitor, markedly suppresses the expression of phosphorylated AKT, yet shows no significant impact on GPER expression. Both G15 and LY294002 can significantly blocked the Rg1-mediated enhancement of osteogenesis capacity in the GIOP model. In contrast, when both the agonists G1 of GPER and LY294002 were added, G1 increased the relative expression of mRNA and protein of GPER, but not the expression of osteogenic capacity and osteogenic markers. ConclusionsThis study investigates the mineralization effects and mechanisms of Ginsenoside Rg1 both in vitro and in vivo. For the first time, we propose that Rg1 might regulate osteogenesis by modulating AKT phosphorylation through mediating GPER expression within the PI3K/AKT pathway in the GIOP model. This discovery introduces novel targets and avenues for osteoporosis treatment.

Effects of four soil types on growth responses and nutrient stoichiometry in Phellodendron chinense seedlings

Abstract Phellodendron chinense is an extraordinary medicinal plant, and its stem bark is a famous traditional Chinese medicine in China, containing a number of phytochemicals with biological and pharmacological functions. Studies have shown that the medicinal ingredients in P. chinense from various regions are different, as soil types might be important factors affecting the growth and quality of P. chinense. In this study, the effects of acidic purple soil, alkaline purple soil, yellow soil and red soil on the growth, nutrient element accumulation and partitioning in P. chinense seedlings were studied. Our results showed that the biomass of leaves and stems in acidic purple soil was significantly higher than in other soils, and the root biomass was significantly lower than that in yellow soil. C, N, P and Ca contents cultured in acidic purple soil were the highest compared to other soils, and K and Mg content were the highest in yellow soil and red soil, respectively. The distribution of carbon between different organs can reflect environmental stress. N has become a limiting factor for the growth and development of P. chinense seedlings. C:N and C:P ratios in the leaves were significantly lower than those in the stem and roots. Among four soil types, the highest N:P ratio was 1.65 in P. chinense seedlings. These results suggest that four soil types may significantly affect the accumulation and distribution of biomass and nutrient elements in P. chinense seedlings. The characteristic patterns in different organs have different responses. Acidic purple soil is more suitable for the growth of P. chinense. These findings will help to understand the distribution characteristics and requirements of nutrient elements in P. chinense seedlings, and further provide a theoretical basis and reference for site selection and cultivation strategy.

Investigation of the response of Platycodongrandiflorus (Jacq.) A. DC to salt stress using combined transcriptomics and metabolomics

BackgroundPlatycodon grandiflorus (Jacq.) A. DC is a famous traditional Chinese medicine in China and an authentic medicine in Inner Mongolia. It has been traditionally used as an expectorant in cough and also has anti-inflammatory and other pharmacological effects. As a homologous plant of medicine and food, P. grandiflorus is widely planted in Northeast China. Soil salinity isa limiting factor for its cultivation. In this study, we comprehensively described the physiological characteristics of P. grandiflorus and combined transcriptomics and metabolomics to study the response of roots of P. grandiflorus to salt stress.ResultsOverall, 8,988 differentially expressed genes were activated and significantly altered the metabolic processes. In total, 428 differentially abundant metabolites were affected by salt stress. After moderate and severe salt stress, most of the differentially abundant metabolites were enriched in the L-phenylalanine metabolic pathway. Through the comprehensive analysis of the interaction between key genes and metabolites, the main pathways such as lignin compound biosynthesis and triterpene saponin biosynthesis were completed. The relative content of compounds related to lignin biosynthesis, such as caffeic acid, coniferin, and syringing, increased under salt stress, and the related genes such as PAL, C4H, and the key enzyme gene UGT72E2 were activated to adapt to the salt stress. Platycodon saponin is one of the major triterpene saponins in P. grandiflorus, and Platycodin D is its most abundant major bioactive component. Under severe salt stress, Platycodin D level increased by nearly 1.77-fold compared with the control group. Most of the genes involved insynthetic pathway of Platycodin D, such as HMGCR, GGPS, SE, and LUP, were upregulated under salt stress.ConclusionSalt stress led to a decrease in the biomass and affected the activities of antioxidant enzymes and contents of osmotic regulators in the plant. These results provided not only novel insights into the underlying mechanisms of response of P. grandiflorus to salt stress but also a foundation for future studies on the function of genes related to salt tolerance in the triterpenoid saponin biosynthesis pathway.

Translation Studies of Traditional Chinese Medicine in China: Achievements and Prospects

Given the accelerated pace of traditional Chinese medicine (TCM) translation studies and their increasing popularity in China, it is necessary to make a comprehensive review. This study explores the recent development and hotspots on TCM translation studies, based on research articles published between 1992 and 2020 in key journals in China National Knowledge Infrastructure database, and it employs bibliometric methods to analyze the status quo, hotspots, and future trends of TCM translation studies. The study identifies the main researchers, their affiliations, and frequently cited papers and examined them from the perspective of keywords and burst terms. We find that TCM translation studies are rapidly increasing, topics and fields are increasingly covered, and cultural elements and their significance are increasingly considered. More perspectives and topics should remain to be considered. Thus, the TCM-related corpus should be expanded to enable in-depth studies. Further, more studies should be conducted on the training of TCM translators and interpreters.

First Report of 16SrI-B Subgroup Related Phytoplasma Associated with Yellows Symptoms of Rubus cochinchinensis in China.

Rubus cochinchinensis, an important traditional Chinese medicine in China is used to treat rheumatic arthralgia, bruises and lumbocrural pain (He et al.2005). In January 2022, yellow leaves of R. cochinchinensis were found in Tunchang City, Hainan Province, a tropical island in China. Chlorosis spread along the direction of vascular tissue while the leaf veins remain green (Fig. 1). In addition, the leaves were slightly shrunken and the growth vigor is poor (Fig. 1). By survey, we found the incidence of this disease was about 30%. Three etiolated samples and three healthy samples (0.1g each) were used to extract total DNA (TIANGEN plant genomic DNA extraction kit). Using nested PCR method, phytoplasma universal primers P1 / P7 (Schneider et al., 1995) and R16F2n / R16R2 (Lee et al. 1993) were used to amplified phytoplasma 16S rDNA gene. Primers rp F1 / R1 (Lee et al. 1998) and rp F2 / R2 (Martini et al. 2007) were used to amplified rp gene. 16S rDNA gene and rp gene fragments were amplified from three leaf etiolated samples, but not from healthy samples. The amplified fragments were cloned and sequenced, and the sequences were assembled by DNASTAR11. By sequence alignment, we found the obtained 16S rDNA and rp gene sequences of three leaf etiolated samples were same. The length of 16S rDNA fragment was 1237 bp (accession number: ON944105) and the length of rp gene fragment was 1212 bp (accession number: ON960069). The phytoplasma strain was named as 'R. cochinchinensis' yellows leaf phytoplasma (RcT), RcT-HN1 strain. The 16S rDNA gene sequence of RcT-HN1is 99.8% consistent with 16SrI-B subgroup members such as the 'Brassica napus' dwarf phytoplasma strain WH3 (MG599470.1), Chinaberry yellows phytoplasma strain LJM-1(KX683297.1) and Arecanut yellow leaf disease phytoplasma strain B165 (FJ694685.1). The rp gene sequence of RcT-HN1 is 100% consistent with rpI-B subgroup members such as the 'Salix tetradenia' witches'-broom phytoplasma strain YM-1 (KC117314.1) and Chinaberry witches'-broom phytoplasma strain Hainan (EU348781.1). The phylogenetic tree analysis, based on concatenated 16S rDNA-rp gene sequence of same group phytoplasma by MEGA 7.0 employing neighbor-joining (NJ) method with 1000 bootstrap value, were performed (Kumar et al., 2016). The results showed that RcT-HN1 phytoplasma strain formed a subclade in aster yellows group B subgroup (Fig. 2). The virtual RFLP analysis based on the 16S rRNA gene fragment of RcT-HN1 phytoplasma strain was performed by the interactive online phytoplasma classification tool iPhyClassifier (Zhao et al., 2009). The results showed that the phytoplasma strain was same as the reference pattern of the onion yellows phytoplasma of 16SrI-B (GenBank accession: AP006628), and the similarity coefficient was 1.00. This is the first report that 16SrI-B subgroup related phytoplasma infected R. cochinchinensis and caused yellows symptoms in China. The discovery of the disease is helpful to the study of the spread of phytoplasma-related diseases and protect R. cochinchinensis resources.
