RESUMO
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.

RESUMO
Objective To detect the changes in the immune function of opioid-dependent subjects during the withdrawal stage through the administration of Jitai tablet.Methods Subjects were treated as Jitai tablet alone,Jitai tablet plus buprenorphine and placebo,in a randomized,double-blind,placebo-controlled trial.Before and after the 14th day of withdrawal,levels of immunoglobulin (IgM,IgA,IgG),T cell subsets (CD3+,CD4+,CD8+,CD4+/CD8+) and cytokines (IL-2,IFN-γ,IL-4,IFN-γ/IL-4) were detected.Results Compared with healthy people,immunity function before withdrawal among the opioid abusers showed higher levels of IgM,IL-2,IFN-γ,IL-4 and lower level of CD3+ T,as (1.67 ± 0.87) g/L,(14.44 ± 13.50)%,(20.23 ± 15.10)%,(1.97 ± 1.59)%,(47.01 ± 13.62)%,respectively,with difference statistically significant (P<0.05).There was no big difference of other immunity indicators between the two groups (P>0.05).At the 14th day of withdrawal in placebo group,levels of IL-4 returned to normal while IFN-γ/IL-4 ratio increased by 3.43 times (P<0.05).Levels of IgA,IgG,CD4+ and CD4+/CD8+ ratio fluctuated within normal range.There were no significant changes in other immunity indicators (P>0.05).Compared with placebo group,fluctuation of IgG and IgM decreased in Jitai group during withdrawal period,together with a normal level of IgM at the 14th day.Level of IL-4 abnormally rose up by 0.54 times in Jitai tablet plus buprenorphine group,while IFN-γ/IL-4 ratio been switched back at the 14th day of withdrawal.Other immune indicators were not affected by medical interventions.Conclusion We noticed that certain impairment of the immune function might be restored by Jitai tablet during the withdrawal period.

RESUMO
BACKGROUND:The new formulation and preparation technology of new drugs have become a hot spot for improving the utilization of polypeptides. In particular, the development of nanotechnology in recent years has promoted the clinical application of polypeptide drugs. OBJECTIVE:To review the current research of nanoparticles as carriers of polypeptide drugs for oral administration. METHODS:A computer-based search of CNKI database and SCI database was performed for relevant articles published from 1996 to 2014 by using the keywords of“protein, peptide drugs, nanoparticles, oral administration”in Chinese and English, respectively. RESULTS AND CONCLUSION:The encapsulation efficiency, release rate of drug delivery, stability of nanoparticles in the gastrointestinal tract and penetrability of the intestinal mucosa are determined by many factors, such as the kind, size, surface charge and modification of nanoparticles. The nanoparticles can increase the stability of protein drugs and improve the bioavailability of drugs. The targeting property of the nanoparticles can decrease the adverse reactions of some drugs. The release effect of the nanoparticles can decrease the dosage of drugs and increase the drug circulating time. However, there are stil many problems to be solved in nanotechnology:the activities of some protein drugs are lost in the preparation process;theencapsulation efficiency and drug loading need to be improved;protein burst release cannot be solved completely;the mass production of nanoparticles is stil difficult.
