[Series of group standards of Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions].

Drug instructions,the statutory and technical documents recording effectiveness and safety information,are an important basis for guiding doctors,pharmacists,and patients to use drugs rationally,and their scientificity,standardization,and accuracy directly affect the medication safety of the public. The sections of adverse drug events,contraindications,precautions,warnings,and application for specific populations in drug instructions directly express safety information and measures for rational use of drugs. In the drug life cycle,marketing authorization holders( MAHs) need to update safety information in the instructions promptly to ensure the safety and effectiveness of clinical drug medication. At present,revising instructions is an important measure to control drug risks. In the drug life cycle,in order to standardize the revision of safety information in the instructions by MAHs and eliminate inexact terms such as " unclear",the Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,have been established under the guidance of Standardization Department,China Association of Chinese Medicine. Therefore,on the basis of the existing rules and regulations,the standardized technical procedures for revising instructions came into being to help clinical safe and rational medication of drugs,and implement the strategy of " Healthy China".

[Interpretation of Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions].

Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,were proposed by Professor ZHANG Bing from Research Center for Pharmacovigilance and Rational Use of Traditional Chinese Medicine,and underwent centralized management by Chinese Association of Chinese Medicine. They were officially released on July 23 and implemented on July 31,2021. The series of group standards consist of six sections,including general principles,adverse drug events,contraindications,precautions,application for special populations,and warnings. The section of general principles is comprised of holistic and programmatic expressions,which explain the general technical requirements for revising the marketed Chinese patent medicine instructions. The other five sections focus on information collection,screening,transformation,and illustration of specific items,forming a standardized revision technical process. This series of standards is the result of multiple rounds of research and the suggestions of more than 200 experts in different professional fields of " medicine-pharmacy-management-law-enterprise" have been gathered therein to reach a consensus. With the purposes of establishing standardized technical specifications for the revision of safety information in the marketed Chinese patent medicine instructions,guiding marketing authorization holders in revising the instructions,filling the gaps in the research of Chinese patent medicine instructions,promoting the deve-lopment of pharmaceutical care and academic research,and encouraging the rational and safe medication of Chinese patent medicine,the series of group standards is of great significance.

[Technical specification for Instructions for Clinical Application of Chinese Patent Medicines in China Association of Chinese Medicine].

In order to solve the problems of confusion in clinical medication and imperfect instructions in Chinese patent medicines(CPMs), the Standardization Department of the China Association of Chinese Medicine and Center for Pharmacovigilance and Rational use of Chinese Medicine in Beijing University of Chinese Medicine jointly compiled the Instructions for Clinical Application of Chinese Patent Medicines(CPMs). As the interpretation and supplement of drug instruction information, it aims to guide clinical safety and rational use of CPMs. In addition, the technical specification for clinical application description of CPMs has been formulated, which covers the seven processes of "carding instructions, clinical investigation, data retrieval, data screening, evidence classification, path transformation and writing format". It will enable readers of Instructions for Clinical Application of Chinese Patent Medicines to understand the work behind the compilation.

[Pre-searching during formulation of expert consensus on clinical application of Chinese patent medicines:Yanshen Jianwei Capsules as example].

The formulation of expert consensus on clinical application of Chinese patent medicines, in means of exploring the effective combination of experience and evidence to form a research method in line with the characteristics of Chinese patent medicines, is an important transitional stage for clinical researches on Chinese patent medicines. Pre-searching is a new step in the formulation of expert consensus on clinical application of Chinese patent medicines. Before steps of interview and investigation on clinical application, pre-searching is conducted to collect publications and literature on certain variety and similar Chinese patent medicines; the publications on related medical classics and formulas of this variety; the recommendation condition of this variety in clinical practice guidelines and expert consensus; and the medication regimens recommended in disease-specific guidelines. Pre-searching is designed to know about the advantages of certain variety of Chinese patent medicine as well as its potential problems recorded in the literature, which is helpful to find out the clinical positioning of Chinese patent medicines, develop reasonable clinical questions and provide ideas for formal literature searching. However, it is not the direct basis for developing clinical questions. Moreover, interviews and investigations are still needed to further clarify the clinical positioning of Chinese patent medicines and develop reasonable questions. This paper took expert consensus on clinical application of Yanshen Jianwei Capsules as an example to introduce the pre-searching process and methods used during formulation of expert consensus on clinical application of Chinese patent medicines, and to further discuss the role of pre-searching to facilitate the formulation of clinical questions on selection of participants, interventions, controls and outcomes.

Comparative efficacy of Chinese herbal injections for treating acute cerebral infarction: a network meta-analysis of randomized controlled trials.

BACKGROUND: Chinese herbal injections (CHIs) are prepared by extracting and purifying effective substances from herbs (or decoction pieces) using modern scientific techniques and methods. CHIs combined with aspirin + anticoagulants + dehydrant + neuroprotectant (AADN) are believed to be effective for the treatment of acute cerebral infarction (ACI). However, no randomized controlled trial (RCT) has been performed to directly compare the efficacies of different regimens of CHIs. Therefore, we performed a systematic review and network meta-analysis (NMA) to compare the efficacies of different regimens of CHIs for ACI. METHODS: We conducted an overall and systematic retrieval from literature databases of RCTs focused on the use of CHIs to treat ACI up to June 2016. We used the Cochrane Handbook version 5.1.0 and CONSORT statement to assess the risk of bias. The data were analyzed using STATA 13.0 and WinBUGS 1.4.3 software. RESULTS: Overall, 64 studies with 6225 participants involving 15 CHIs were included in the NMA. In terms of the markedly effective rate, Danhong (DH) + AADN had the highest likelihood of being the best treatment. In terms of the improvement of neurological impairment, Shuxuening (SXN) + AADN had the highest likelihood of being the best treatment. Considering two outcomes, injections of SXN, Yinxingdamo (YXDM), DH, Shuxuetong (SXT), HongHuaHuangSeSu (HHHSS), DengZhanXiXin (DZXX) and Shenxiong glucose (SX) plus AADN were the optimum treatment regimens for ACI, especially SXN + AADN and YXDM + AADN. CONCLUSIONS: Based on the NMA, SXN, YXDM, DH, SXT, HHHSS, DZXX and SX plus AADN showed the highest probability of being the best treatment regimens. Due to the limitations of the present study, our findings should be verified by well-designed RCTs.

Comparative efficacy of Chinese herbal injections for treating chronic heart failure: a network meta-analysis.

BACKGROUND: On account of deterioration of chronic heart failure (CHF) and extensive exploration of Chinese herbal injections (CHIs), we performed a network meta-analysis to investigate the efficacy of CHIs (Huangqi injection, Shenfu injection, Shengmai injection, Shenmai injection, Shenqi Fuzheng injection, Yiqifumai injection) on the basis of western medicine (WM) treatment in CHF. METHODS: Literature search was conducted in Embase, the Cochrane Library, Pubmed, Chinese Biological Medicine Database, China National Knowledge Infrastructure, Wanfang Database, Chinese Scientific Journal Database from inception to June 12nd 2017, and study selection was abided by a prior eligible criteria. RESULTS: Ultimately, a total of 113 randomized controlled trials (RCTs) were enrolled. The clinical data of the effective clinical rate, left ventricular ejection fraction, cardiac output and others outcomes was estimated by Stata software and Winbugs software. Risk of bias was assessed by Cochrane Collaboration's tools. Integrating the each outcome's results, a combination of Shengmai injection/Shenmai injection and WM obtain a first rank in most outcomes, particularly primary outcomes. CONCLUSIONS: In conclusion, on the basis of WM, Shengmai injection or Shenmai injection may be a perforable treatment in CHF. In terms of insufficient of this study, more high quality RCTs needed to implement to support our conclusions.
