Objective To establish a method for the quantitative determination of AGP (Acanthopanax giraldii Harms polysaccharides). Methods AGP content was determined by DNS Method. The absorptions of processed samples were tested at the wavelength of 520 nm. Results Contrast to glucose, the linear range was 46.6～233.0 mg/L (r=0.999 2), the average recovery was 99.0%～102.1%, RSD=3.52%, n=5. The polysaccharides measured in 3 batches of samples were 1.3～1.9 mg/g. Conclusion The method is sensitive,steady with good repeatability, and help to the qulity control of Acanthopanax giraldii Harms.

Objective This study aimed to conduct a systematic review and meta-analysis of randomized controlled trials(RCTs)assessing the clinical efficacy of acupuncture for chronic stable angina(CSA).Methods PubMed,The Cochrane Library,Embase,CNKI,VIP,WanFang Data,CBM databases,ClinicalTrial.gov and Chinese Clinical Trial Registry were electronically searched to collect randomized controlled trials(RCTs)of acupuncture for CSA and only RCTs that included acupuncture as the sole or combination of acupuncture in the treatment of CSA.The retrieval period was from the establishment of the database to May 19,2022.The primary outcome measure was the frequency of angina attacks,and the secondary outcome measures were angina efficacy,total effective rate of ECG improvement,nitroglycerin use after treatment,patient-perceived overall effectiveness,performance on the Six-Minute Walk Test(6-MWT),depression as measured by the anxiety as measured by the Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS),adverse effects.Results Twelve studies with a total of 1605 case subjects were included and grade quality of evidence reviews had 1 outcomes as medium quality evidence,5 outcomes as low quality evidence and 4 outcomes as very low quality evidence.Acupuncture treatment resulted in significantly greater reductions in angina attacks,visual analog scale(VAS),6-minute walk test,angina efficacy,electrocardiogram improvement rate,angina efficacy,total clinical response rate.Conclusion The efficacy of acupuncture combined with western medicine in treating CSA is better than that of Western medicine alone,thanks to restricted by the number and quality of included researchs,higher quality studies are required to prove above conclusions.
