[Evidence of clinical randomized controlled trial study in treatment of acute cerebral infarction with traditional Chinese medicine in recent five years].

To systematically search and sort out the clinical randomized controlled trial(RCT) on the prevention and treatment of acute cerebral infarction with traditional Chinese medicine(TCM) by using the method of evidence map, and to understand the evidence distribution of related studies. CNKI, Wanfang, VIP, CBM, PubMed, EMbase, Cochrane Library and Web of Science were retrieved from January 2016 to September 2020, and literatures related to the prevention and treatment of acute cerebral infarction with traditional Chinese medicine were included. Text description combined with table and bubble chart were used to analyze the distribution characteristics of evidence. A total of 1 102 clinical articles in recent five years were retrieved. The annual trend of clinical study publication, study size, TCM therapy category and main scheme, and study literature quality were analyzed. We find that TCM treatment of acute cerebral infarction has become a hot topic of clinical research, the number of literature showed a trend of increased year by year, various means of intervention of TCM in the treatment of the advantages of increasingly highlight. Follow-up clinical research should highlight the characteristics of TCM: in the analysis of outcome indicators; increase the neuropsychological patients after stroke and cognitive ability, and the theory of combined treatment of TCM disease when thoughts; At the same time, the quality of clinical research needs to be improved. At present, there is still a lack of unified standards for the production of evidence map. This study is the first to explore the application of evidence map to summarize and display the clinical research status of TCM treatment of acute cerebral infarction, and combine it with the setting of priority areas of TCM clinical research, so as to provide a reference basis for determining the priority topic selection of TCM treatment optimization research.

[Analysis of status quo of outcome indicators of randomized controlled trials in treatment of acute ischemic stroke with acupuncture in recent three years].

To analyze the use of outcome indicators of randomized controlled trial(RCT) of acupuncture in the treatment of acute ischemic stroke in recent three years, so as to provide a basis for building a study on the core outcome indicators for the treatment of acute ischemic stroke with acupuncture. The RCTs of acupuncture treatment for acute ischemic stroke in recent three years were collec-ted through computer retrieval of eight Chinese and English databases and two clinical trial registries at home and abroad. Literature was screened out, and data was extracted. Risk of assessment bias tool Cochrane 6.1 was used for bias risk assessment, outcome indicators were summarized and analyzed. A total of 47 RCTs were included, and 3 studies were trials registration scheme. Outcome indicators were divided into 6 categories according to functional attributes, namely physical symptoms/signs, physical and chemical examination, quality of life, traditional Chinese medicine symptoms/syndromes, safety events and long-term prognosis. The study found that in addition to the common problems in previous studies covered by the status quo of outcome indicators selection of RCT of acupuncture in the treatment of acute ischemic stroke, there were also the other problems as follows: emphasis on macroscopic efficacy indicators but neglect of acupuncture specific indicators, lack of characteristic indicators and economic indicators of traditional Chinese medicine therapy, and unification of indicators measurement tool and measurement time point. In the future, the outcome indicators set for the treatment of acute ischemic stroke with acupuncture shall be established, and the core outcome indicators set shall be in line with the characteristics of traditional Chinese medicine treatment.

[Overview of systematic reviews/Meta-analysis of Xingnaojing Injection in treatment of cerebral ischaemic stroke].

There have been many clinical trials, systematic reviews/Meta-analysis proving that Xingnaojing Injection has a good clinical efficacy in treatment of cerebral ischaemic stroke, but with fewer comprehensive descriptions. In this study, an overview of systematic reviews/Meta-analysis of Xingnaojing Injection in treating cerebral ischaemic stroke was performed to provide current situation of evidences and basis for clinical practice. CNKI, Wanfang, VIP, CBM, EMbase, PubMed, Cochrane Library, Web of Science were retrieved through computers. A total of 6 literatures were included in this study. By AMSTAR-2 checklist and GRADE, the quality of included systematic reviews and the efficacy of Xingnaojing Injection were evaluated. The results of AMSTAR-2 checklist showed an extremely low quality for all of the 6 systematic reviews. According to the results of GRADE evaluation, among 55 outcomes, there were 2 outcomes with a medium quality, 4 outcomes with a low quality and 49 outcomes with an extremely low quality. The 6 systematic reviews reached a consistent conclusion that Xingnaojing Injection was effective in the treatment of cerebral ischaemic stroke. This therapy could improve the total efficacy, neurological deficit scores, hemodynamic and hemodynamic parameters. However, the methodolo-gical quality of all literatures was extremely low. The evidence levels of outcomes were between extremely low to medium. The effectiveness of Xingnaojing Injection in the treatment of cerebral ischaemic stroke still needs to be further verified by more high-quality studies. In the future, relevant clinical studies and systematic reviews/Meta-analysis shall be carried out in a strict accordance with relevant regulations.

[Overview of systematic reviews of Panax notoginseng saponins in treatment of acute cerebral infarction].

To overview the systematic reviews of Panax notoginseng saponins in the treatment of acute cerebral infarction. CNKI, CBM, Wanfang, VIP, PubMed, Cochrane Library and EMbase databases were retrieved to collect the systematic reviews of the efficacy of P. notoginseng saponins in the treatment of acute cerebral infarction. The retrieval time was from the time of database establishment to January 2021. After two researchers independently screened out the literature and extracted the data, AMSTAR-2 scale was used to evaluate the methodological quality of the included systematic reviews, GRADE system was used to grade the quality of evidences of the outcome indicators, and the efficacy evaluation was summarized. A total of 5 systematic reviews were included. AMSTAR-2 evaluation results showed that 3 items were relatively complete, while 4 items had a poor overall quality. P. notoginseng saponins combined with conventional Western medicine therapy was superior to single conventional therapy in the recovery of neurological function, enhancement of the total effective rate in clinic, and improvement of activities of daily living. GRADE evaluation results showed that the quality of evidence was from low quality to very low quality. In conclusion, in the treatment of acute cerebral infarction, P. notoginseng saponins can improve the clinical efficacy, with a good safety but a not high methodological quality and a low evidence quality. It is suggested that high-quality clinical studies shall be further carried out to provide evidence-based basis for the application of P. notoginseng saponins in the treatment of acute cerebral infarction.

Systematic Review and Meta-Analysis on Randomized Controlled Trials on Efficacy and Safety of Panax Notoginseng Saponins in Treatment of Acute Ischemic Stroke.

OBJECTIVE: To assess the efficacy and safety of PNS on antiplatelet therapy in the treatment of AIS. METHODS: We searched 7 literature databases and 2 clinical studies databases for randomized controlled studies (RCTs) evaluating PNS as an adjuvant therapy for AIS. Relevant studies were retrieved and screened, and data were extracted independently by two reviewers. The quality of the included studies was assessed using the Cochrane Risk Assessment Tool. Meta-analysis was carried out with the Rev Man 5.4 software. RESULTS: Of 8267 records identified, 43 RCTs met our inclusion criteria (n = 4170 patients). Patients assigned to PNS with conventional treatments (CTs) had improved functional independence at 90 days compared with those assigned to CTs alone (RR = 1.87, 95% CI = 1.37, to 2.55, P < 0.0001). Patients who received PNS combined with CTs showed significantly high improvements in neurological function among individuals with AIS on the neurologic deficit score (NDS) (MD CSS = -5.71, 95% CI = -9.55 to -1.87, P=0.004; MD NIHSS = -3.94, 95% CI = -5.65 to -2.23, P < 0.00001). The results also showed PNS contributed to a betterment in activities of daily living (ADL) on the Barthel index (MD day 10 BI = 4.86, 95% CI = 2.18, to 7.54, P < 0.00001; MD day 14 BI = 13.92, 95% CI = 11.46 to 16.38, P < 0.00001; MD day 28 BI = 7.16, 95% CI = 0.60, to 13.72, P < 0.00001). In addition, PNS, compared with CTs alone, could significantly improve overall response rate (ORR) (RR NIHSS = 1.20, 95% CI = 1.16, to 1.24, P < 0.00001; RR CSS = 1.15, 95% CI = 1.08, to 1.24, P < 0.0001), hemorheological parameters, maximum platelet aggregation rate (MPAR) (MD = -6.82, 95% CI = -9.62 to -4.02, P < 0.00001), platelet parameters (MD PLT = 4.85, 95% CI = 1.82 to 7.84, P=0.002; MD MPV = -0.79, 95% CI = -1.09 to -0.48, P < 0.00001), and serum CD62P (MD = -0.21, 95% CI = -0.29 to -0.13, P < 0.00001). The incidence of adverse reactions in PNS was lower than that in the control group (RR = 0.62, 95% CI = 0.39 to 0.97, P=0.04). Adverse reactions in the PNS were mild adverse reactions. CONCLUSION: PNS may be effective and safe in treating AIS on ameliorating neurological deficit, improving activities of daily living function, and enhancing antiplatelet effects. However, more high-quality evidence is needed before it can be recommended for routine antiplatelet therapy in patients with AIS.

[Treatment of Rheumatoid Arthritis by Hebi Recipe: an Efficacy Observation].

OBJECTIVE: To observe the auxiliary efficacy and safety of Hebi Recipe (HR)in treating early rheumatoid arthritis (RA). METHODS: Totally 63 early RA patients with Gan-Pi disharmony were randomly assigned to the treatment group [32 cases, treated by HR (one dose per day, taken in two portions for 24 successive weeks) plus Methotrexate (MTX)] and the control group (31 cases, treated by MTX alone). The dosage of MTX was increased from 7.5 mg to 12.5 mg, once per week, 24 weeks as one course of treatment. Efficacy for Chinese medical syndromes, American College of Rheumatology 20 (ACR20) improvement rate, disease activity score in 28 joints (DAS28), laboratory related indices [ESR, rheumatoid factor (RF), C-reactive protein (CRP), anti-cyclic citrullinated peptide (CCP)], and related ultrasonic inspection items (synovium thickness, synovium blood flow classification, effusion of joint), and adverse reactions were observed. RESULTS: The total effective rate (83.9%, 26/31 cases) and ACR20 improvement rate (74.2%, 23/31 cases) were higher in the treatment group than in the control group [60.7% (17/28 cases), 46.4% (13/28 cases); P < 0.05]. Compared with before treatment in the same group, DAS28 score, ESR, RF, CRP, CCP, synovium thickness, synovium blood flow classification, effusion of joint all decreased in the two groups after treatment (P < 0.01, P < 0.05). Compared with the control group after treatment, ACR20 improvement rate, DAS28 score, ESR, RF, CRP, CCP, synovium thickness, synovium blood flow classification, effusion of joint all decreased in the treatment group (P < 0.01, P < 0.05). Liver dysfunction occurred in 1 case of the treatment group. One leucopenia and 2 liver dysfunction occurred in the control group. CONCLUSION: HR could effectively improve joints and systemic symptoms of early RA patients with Gan-Pi disharmony.

Assessment of a pharmacokinetic and pharmacodynamic interaction between simvastatin and Ginkgo biloba extracts in healthy subjects.

1. Ginkgo biloba extract (GBE) is one of the most commonly used herbal remedies worldwide. It is usually concomitantly administrated with statins to treat diseases in geriatric patients. We aim to determine the influence of GBE on the pharmacokinetics (PK) and pharmacodynamics of simvastatin, which is currently unknown. 2. An open-label, randomized, two-period, two-treatment, balanced, crossover study was performed in 14 healthy volunteers. Subjects received simvastatin 40 mg once daily, co-treated with placebo or GBE 120 mg twice daily. Each treatment was administered for 14 d, separated by a wash-out period of 1 month. Simvastatin, simvastatin acid and lipoprotein concentrations were assessed. 3. GBE administration reduced mean simvastatin area under the curve (AUC)0-24, AUC0-∞ and Cmax by 39% (p = 0.000), 36%(p = 0.001) and 32% (p = 0.002), respectively, but did not cause significant differences in simvastatin acid PK or its cholesterol-lowering efficacy. 4. GBE consumption decreased simvastatin system exposure, but did not affect simvastatin acid PK. However, we cannot rule out the possibility for a pharmacodynamic interaction between GBE and simvastatin in vivo.

Effects of Ginkgo biloba extracts on diazepam metabolism: a pharmacokinetic study in healthy Chinese male subjects.

AIM: It has been reported that Ginkgo biloba extract (GBE) is an inducer or inhibitor of microsomal cytochrome P450 (CYP) 2C19, and diazepam is a substrate of CYP2C19. Thus, it could be expected that GBE may alter the metabolism of diazepam. METHODS: The pharmacokinetic parameters of diazepam and one of its metabolites, N-demethyldiazepam, were compared after oral administration of diazepam (10 mg) in the absence or presence of oral GBE (120 mg bid, for 28 days) in 12 healthy volunteers. The pharmacokinetic analysis was performed using a noncompartmental method. RESULTS: The 90% confidence intervals (CIs) of the ratios of mean pharmacokinetic parameters of diazepam presence and absence of GBE were well within the 80-125% bioequivalence range, indicating no pharmacokinetic interaction. The ratio of AUC(0-408) with GBE to AUC(0-408) without GBE was 95.2 (90%CI: 91.6-98.8) and 101.8 (90%CI: 99.4-104.1) for diazepam and N-desmethyldiazepam, respectively. The two drugs were well tolerated, and no drug-related serious adverse events were reported. CONCLUSION: The above data suggest that GBE, when taken in normally recommended doses over a 4-week time period, may not affect the pharmacokinetics of diazepam via CYP2C19 and the excretion of N-desmethyldiazepam in healthy volunteers. No drug-drug interaction was observed between GBE and diazepam.
