Abstract
Several studies have investigated the causative role of the microbiome in the development of rheumatoid arthritis (RA), but changes in the gut microbiome in RA patients during drug treatment have been less well studied. Here, we tracked the longitudinal changes in gut bacteria in 22 RA patients who were randomized into two groups and treated with Huayu-Qiangshen-Tongbi formula (HQT) plus methotrexate (MTX) or leflunomide (LEF) plus MTX. There were differences in the gut microbiome between untreated (at baseline) RA patients and healthy controls, with 37 species being more abundant in the RA patients and 21 species (including Clostridium celatum) being less abundant. Regarding the functional analysis, vitamin K2 biosynthesis was associated with RA-enriched bacteria. Additionally, in RA patients, alterations in gut microbial species appeared to be associated with RA-related clinical indicators through changing various gut microbiome functional pathways. The clinical efficacy of the two treatments was further observed to be similar, but the response trends of RA-related clinical indices in the two treatment groups differed. For example, HQT treatment affected the erythrocyte sedimentation rate (ESR), while LEF treatment affected the C-reactive protein (CRP) level. Further, 11 species and 9 metabolic pathways significantly changed over time in the HQT group (including C. celatum, which increased), while only 4 species and 2 metabolic pathways significantly changed over time in the LEF group. In summary, we studied the alterations in the gut microbiome of RA patients being treated with HQT or LEF. The results provide useful information on the role of the gut microbiota in the pathogenesis of RA, and they also provide potentially effective directions for developing new RA treatments.

International journal of biological sciences. 2020;(10):1708-1717
Abstract
Currently, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2, formerly known as 2019-nCoV, the causative pathogen of Coronavirus Disease 2019 (COVID-19)) has rapidly spread across China and around the world, causing an outbreak of acute infectious pneumonia. No specific anti-virus drugs or vaccines are available for the treatment of this sudden and lethal disease. The supportive care and non-specific treatment to ameliorate the symptoms of the patient are the only options currently. At the top of these conventional therapies, greater than 85% of SARS-CoV-2 infected patients in China are receiving Traditional Chinese Medicine (TCM) treatment. In this article, relevant published literatures are thoroughly reviewed and current applications of TCM in the treatment of COVID-19 patients are analyzed. Due to the homology in epidemiology, genomics, and pathogenesis of the SARS-CoV-2 and SARS-CoV, and the widely use of TCM in the treatment of SARS-CoV, the clinical evidence showing the beneficial effect of TCM in the treatment of patients with SARS coronaviral infections are discussed. Current experiment studies that provide an insight into the mechanism underlying the therapeutic effect of TCM, and those studies identified novel naturally occurring compounds with anti-coronaviral activity are also introduced.

Abstract
Objective: Whether to conduct Sijunzi decoction combined with enteral nutrition (SJZD/EN) in patients with gastric cancer (GC) remains controversial. This study was aimed to systematically analyze the efficacy and safety of SJZD/EN in patients with gastric cancer.Methods: We performed searches in PubMed, MEDLINE, EMBASE, Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), Wanfang database, and Chinese Biomedicine Literature Database (SinoMed) to identify relevant literature comparing SJZD/EN with conventional EN for GC patients. The analysis was carried out with RevMan 5.3.Results: A total of 10 randomized controlled trials (688 patients) were included. Meta-analysis showed a significantly shorter time to flatus (t/h) (MD, -9.45; 95% CI, -10.76 to -8.13; p < 0.00001), a shorter length of hospital stay (t/d) (MD, -5.22; 95% CI, -7.46 to -2.99; p < 0.00001), and a lower incidence of postoperative complications (%) (OR, 0.14; 95% CI, 0.03-0.64; p = 0.01) in the SJZD/EN group than the EN group. Compared with the EN, the SJZD/EN group had a higher level of albumin(g/L) (MD, 2.59; 95% CI, 1.90-3.28; p < 0.00001), prealbumin (mg/L) (MD, 36.81; 95% CI, 13.41-60.20; p = 0.002), transferrin (g/L) (MD, 0.19; 95% CI, 0.10-0.28; p < 0.0001), immunoglobulin G (g/L) (MD, 2.61; 95% CI, 2.12-3.09; p < 0.00001), immunoglobulin A (g/L) (MD, 0.38; 95% CI, 0.31-0.45, p < 0.00001), immunoglobulin M (g/L) (MD, 0.31; 95% CI, 0.22-0.41; p < 0.00001), CD3+ (%) (MD, 6.73; 95% CI, 3.48-9.98; p < 0.0001), CD4+ (%) (MD, 4.32; 95% CI, 3.30-5.33; p < 0.00001), and CD4+/CD8+ (MD, 0.20; 95% CI, 0.11-0.28; p < 0.00001).Conclusions: Sijunzi decoction combined with enteral nutrition appears to have efficacy and safety for gastric cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As an important Chinese herb injection, Aidi injection is composed of the extracts from Astragalus, Eleutherococcus senticosus, Ginseng, and Cantharis. Aidi injection plus paclitaxel-based chemotherapy is often used to in the treatment of non-small cell lung cancer (NSCLC) in China. AIM OF THE STUDY The objective of this study is to further confirm whether Aidi injection can improve the tumor responses and survivals, and reveal its safety, optimal usage and combination with paclitaxel. MATERIALS AND METHODS A meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All randomized controlled trials (RCTs) concerning the Aidi injection plus paclitaxel-based chemotherapy for NSCLC were selected. Main outcomes were objective response rate (ORR), disease control rate (DCR), survivals, quality of life (QOL) and adverse drug reactions (ADRs). All data were extracted by using a standard data extraction form and synthesized through meta-analysis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used for rating the quality of evidence. RESULTS Thirty-one RCTs involving 2058 patients were included, and most trials had an unclear methodological bias risk. The risk ratio (RR) and 95% confidence intervals (CI) of ORR, DCR, QOL, neutropenia, thrombocytopenia, gastrointestinal toxicity and liver injury were as following: 1.32 (1.20-1.46), 1.14 (1.09-1.20), 1.89 (1.66-2.16), 0.61 (0.51-0.74), 0.62 (0.45-0.87), 0.59 (0.49-0.72) and 0.52 (0.36-0.75). Compared to chemotherapy alone, all differences were statistically significant. Subgroup analysis showed that only with the TP, Aidi injection could increase the ORR and DCR. Treatment with 100 ml, 80 ml or 50 ml/time, and 14 days/2 cycles or 21 days/2-4 cycles, Aidi injection could increase the ORR and DCR, respectively. Sensitivity analysis showed that the results had good robustness. None of the trials reported the overall survivals (OS), progression free survival (PFS). The quality of evidences was moderate. CONCLUSIONS Current moderate evidence revealed that Aidi injection plus paclitaxel-based chemotherapy, especially TP can significantly improve the clinical efficacy and QOL for patients with stage III/IV NSCLC. Aidi injection can relieve the risk of hematotoxicity, gastrointestinal toxicity and liver injury in patient with NSCLC receiving paclitaxel-based chemotherapy. The optimal usage may be 50 ml/time and 14 days/2 cycles.

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica. 2019;(11):2353-2358
Abstract
In this paper, Xixian Tongshuan Preparation was used as the research object, and all the chemical components of the 13 traditional Chinese medicines were collected. The target finding technique was used to obtain the key targets of the neuroprotective effect of Xixian Tongshuan Preparation, including 5 glutamate receptors, TGFR-1 and VEGFR-2. Molecular docking technology was used to screen out the potential active components of the above targets and to analyze their mechanism of action. It was found that single component, such as neo-complanatoside and neo-carthamin, in Xixian Tongshuan Preparation could simultaneously act on different targets. The chemical constituents in Ligusticum chuanxiong, Angelica sinensis, Carthamus tinctorius, and Panax pseudo-ginseng could simultaneously act on different neuroprotective-related targets, which reflected the application of multi-components to multi-targets. Point and multiple sites played a key role in protecting neurons against cerebral ischemic injury. This study explains the multi-target mechanism of anti-cerebral ischemic injury in neuroprotection at the molecular level, and provides a certain direction for the clinical application and experimental research of Xixian Tongshuan Preparation.

Bioscience reports. 2018;(5)
Abstract
Clearance of protein-bound uremic toxins (PBUTs) by dialysis is a challenge in the treatment of uremic patients. Shen-Shuai-Ning (SSN), a traditional Chinese medicine formulation, has been used commonly in China to retard kidney disease progression and decrease uremic toxins in chronic kidney disease (CKD) patients, but the effects of SSN on serum PBUTs in dialysis patients were not investigated. We conducted a randomized controlled trial in patients on peritoneal dialysis (PD) at dialysis center of Changzheng Hospital to evaluate the effects of SSN on serum PBUTs. Participants with SSN intervention took 5 g SSN granule three times daily for 12 weeks, while the baseline medications and dialysis prescriptions remained during the study in all patients. The serum concentrations of indoxyl sulphate (IS) and p-cresol sulphate (PCS) were determined by HPLC/MS/MS and biochemical parameters were assessed during the study. Sixty PD patients were enrolled and randomly allocated into SSN group and control group. Total IS level was significantly lower in SSN group than in control group at week 4, 8, and 12 (27.28 ± 18.19, 29.73 ± 19.10, and 29.41 ± 17.61 mg/l compared with 39.25 ± 20.23, 44.86 ± 23.91, and 45.34 ± 33.52 mg/l, respectively). However, there were no statistical difference of total PCS, free forms of IS and PCS concentrations between SSN group and control group during 12 weeks follow-up. Administration of SSN granule orally decreased serum total IS level effectively in uremic patients on PD with good tolerance. Benefits of PD patients' outcomes from IS reduction by SSN awaits further large size and long duration clinical trials to verify.

Abstract
BACKGROUND Oesophageal cancer is the seventh leading cause of cancer death worldwide. Traditional Chinese herbal medicine is sometimes used as an adjunct to radiotherapy or chemotherapy for this type of cancer. This review was first published in 2007 and updated in 2009; this 2016 update is the latest version of the review. OBJECTIVES To assess the efficacy and possible adverse effects of the addition of Chinese herbal medicine to treatment with radiotherapy or chemotherapy for oesophageal cancer. SEARCH METHODS We searched the Cochrane Upper Gastrointestinal and Pancreatic Diseases Group Trials Register, the Cochrane Library, MEDLINE, EMBASE, Allied and Complementary Medicine Database (AMED), China National Knowledge Infrastructure (CNKI), VIP database, Wanfang database and the Chinese Cochrane Centre Controlled Trials Register up to 1 October, 2015. We also searched databases of ongoing trials, the Internet and reference lists. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing the use of radiotherapy or chemotherapy with and without the addition of Chinese herbal medicine. DATA COLLECTION AND ANALYSIS At least two review authors independently extracted data and assessed trial quality. MAIN RESULTS We tried to contact the 142 study authors by telephone, and finally included nine studies with 490 participants. All included studies were conducted in China, and allocated advanced oesophageal cancer patients to radiotherapy or chemotherapy groups, with and without additional Chinese herbal medicine. Quality of life, short-term therapeutic effects, TCM symptoms and adverse events caused by radiotherapy or chemotherapy were reported in these studies. Overall, we considered the trials to be at unclear or high risk of bias.The quality of life measure was conducted before and after the intervention; our analysis showed a beneficial effect, both in number of participants experiencing an improvement (risk ratio (RR) 2.20, 95% confidence interval (CI) 1.42 to 3.39; 5 RCTs, 233 participants, change of performance status score ≥ 10) and number of participants experiencing a deterioration (RR 0.41, 95% CI 0.27 to 0.62; 6 RCTs, 287 participants, change of performance status score ≤ 10). We judged this to have low quality evidence, downgrading quality of evidence for risk of bias and imprecision, and upgrading quality of evidence for the large effect.For short-term therapeutic effects, the results suggest that traditional Chinese medicine (TCM) has a positive impact on improvement (complete response + partial response) (RR 1.17, 95% CI 1.02 to 1.35; 8 RCTs, 450 participants), moderate quality evidence and downgrading for risk of bias. There was no significant difference for progressive disease (RR 0.73, 95% CI 0.52 to 1.01; 8 RCTs, 450 participants), low quality evidence and downgrading for risk of bias and imprecision. Three studies assessed this outcome after four weeks or three months' follow-up, the remaining studies gave no detailed information for this outcome. TCM symptoms, which was similar to short-term therapeutic effects evaluated with TCM clinical criteria, was diagnosed in two studies of 88 people at the end of the intervention. The results suggest that TCM has a positive impact on both total effectiveness (RR 1.84, 95% CI 1.20 to 2.81) and ineffectiveness (RR 0.22, 95% CI 0.05 to 0.93); we judged the studies to have very low quality evidence, downgrading for risk of bias and imprecision.Nine studies reported a series of adverse events caused by radiotherapy or chemotherapy at the end of the intervention, including mucositis, radiation oesophagitis, arrest of bone marrow, gastrointestinal reactions, renal and hepatic impairment, white blood cell descent, neurotoxicity, cardiac toxicity and anaemia. For those containing multiple studies, we conducted a pooled analysis. As a result, TCM showed a significant effect on radiation oesophagitis (RR 0.66, 95% CI 0.47 to 0.94; 2 RCTs, 90 participants), gastrointestinal reactions (RR 0.54, 95% CI 0.36 to 0.81; 4 RCTs, 268 participants) and white blood cell descent (RR 0.60, 95% CI 0.44 to 0.83; 4 RCTs, 224 participants). The quality of evidence was low or very low, downgrading for risk of bias and imprecision. AUTHORS' CONCLUSIONS We currently find no evidence to determine whether TCM is an effective treatment for oesophageal cancer. The effect of TCM on short-term therapeutic effects is uncertain. TCM probably has positive effects on quality of life and on some adverse events caused by radiotherapy or chemotherapy in advanced oesophageal cancer patients undergoing radiotherapy or chemotherapy. The results of the review need to be interpreted cautiously owing to overall low quality evidence. Future trials should be large and correctly designed to detect important clinical effects and minimise risk of bias.

Journal of traditional Chinese medicine = Chung i tsa chih ying wen pan. 2015;(5):528-36
Abstract
OBJECTIVE To observe the efficacy of a traditional Chinese medicine, Shenzhuo formula, on patients with diabetic kidney disease (DKD). METHODS Eighty-eight outpatients with DKD were enrolled. Changes in estimated glomerular filtration rate (eGFR), creatinine clearance, serum creatinine, blood-urea-nitrogen, albuminuria, glycosylated hemoglobin (HbA1C), blood pressure, and lipid profile were measured and analyzed before and after intervention with Shenzhuo formula for 1, 3, 6, 9, 12, and 18 months. RESULTS Compared with the baseline amounts, serum creatinine decreased, and eGFR and creatinine clearance increased, significantly after intervention for 1, 3, 6, 9, 12, and 18 months (all P < 0.05). Mean eGFR increased by 2.11 mL/min per 1.73 m²/y after 18-month treatment. Urinary protein at 24 h decreased significantly after 1, 3, 9, and 12 months (P < 0.05). HbA1C decreased significantly (P < 0.05) after 3, 6, 9, 12, and 18 months, and systolic blood pressure decreased significantly (P < 0.05) after 1, 3, and 6 months. Total cholesterol decreased significantly (P < 0.05) after 1, 3, 6, and 18 months. Triglyceride and low-density lipoprotein-cholesterol decreased significantly (P < 0.05) after 1 and 3 months. CONCLUSION Shenzhuo formula can improve eGFR and possibly slow DKD progression. Shenzhuo formula can also lower HbA1C, lipid levels and blood pressure.

Abstract
This systematic review and meta-analysis assessed the efficacy and safety of Dang shen [Codonopsis pilosula (Franch.) Nannf., root] formulae for the treatment of chronic obstructive pulmonary disease (COPD). English and Chinese databases were searched, and 48 randomized controlled trials were included. Dang shen formulae improved lung function forced expiratory volume in 1 s compared with conventional pharmacotherapy (CP) [mean difference (MD) 0.22 L, 95% confidence interval (CI) 0.13-0.31, p < 0.001, I(2) = 5%] and quality of life (St. Georges Respiratory Questionnaire) compared with placebo (MD -7.19, 95% CI -10.82 to -3.56, p < 0.001, I(2) = 0%) and when combined with CP versus CP (MD -9.05, 95% CI -12.72 to -5.38, p < 0.001, I(2) = 89%). Dang shen formulae also increased distance walked in 6 min when combined with CP versus CP alone (MD 51.43 m, 95% CI 30.06-72.80, p < 0.001, I(2) = 27%) and reduced frequency/days with COPD exacerbations. Risk of bias was evaluated using the Cochrane tool. Methodological shortfalls were identified. Adverse events were low and not different between intervention and control groups. Thirty-three events were reported, including gastrointestinal upset, dry mouth, and insomnia. Dang shen formulae appear to improve some aspects of the included COPD outcomes. However, owing to methodological flaws, the current evidence is inadequate to support the routine use of Dang shen formulae outside of Chinese medicine practice. However, these results justify further investigation.

Abstract
CONTEXT Living in a prediabetes state significantly increases a patient's risk for both diabetes and cardiovascular disease. Tianqi capsule, containing 10 Chinese herbal medicines, is used in China for the treatment of type 2 diabetes mellitus (T2DM). OBJECTIVE The purpose of this study was to assess whether Tianqi prevented T2DM in subjects with impaired glucose tolerance (IGT) over the course of a 12-month treatment. METHODS Individuals with IGT were randomly allocated in a double-blind manner to receive Tianqi (n = 210) or a placebo (n = 210) for 12 months. Oral glucose tolerance tests were conducted every 3 months to assess the development of diabetes or restoration to normal glucose tolerance. All subjects received the same lifestyle education. The primary endpoint was the conversion of IGT to T2DM. Body weight and body mass index were observed. Adverse effects were monitored. RESULTS Of the 420 enrolled subjects with IGT, 389 completed the trial (198 in the Tianqi group and 191 in the placebo group). At the end of the 12-month trial, 36 subjects in the Tianqi group (18.18%) and 56 in the placebo group (29.32%) had developed diabetes (P = .01). There was a significant difference in the number of subjects who had normal glucose tolerance at the end of the study between the Tianqi and placebo groups (n = 125, 63.13%, and n = 89, 46.60%, respectively; P = .001). Cox's proportional hazards model analysis showed that Tianqi reduced the risk of diabetes by 32.1% compared with the placebo. No severe adverse events occurred in the trial. There were no statistical differences in body weight and body mass index changes between the Tianqi group and the placebo group during the 12-month trial. CONCLUSIONS Treatment with a Tianqi capsule for 12 months significantly decreased the incidence of T2DM in subjects with IGT, and this herbal drug was safe to use.
