Guideline for clinical comprehensive evaluation of Chinese patent medicine (2022 version) / 中国中药杂志

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.

Overview of systematic reviews of Chinese herbal injections for sepsis / 中国中药杂志

In this study, an overview of systematic reviews/Meta-analysis(SR/MA) of Chinese herbal injections for sepsis was performed to provide references for clinical practice and promote the quality improvement of clinical evidence. Eight Chinese and English databases such as CNKI, Medline, and EMbase were electronically searched for SR/MA of Chinese herbal injections for sepsis from database inception to June 2022. AMSTAR 2, PRISMA 2020, and GRADE system, combined with Recommendations for Clinical Evidence Grading on Traditional Chinese Medicine Based on Evidence Body, were applied to evaluate the methodological quality, reporting quality, and evidence quality of the included articles. Twenty-seven articles of SR/MA were included, containing four Chinese herbal injections(Xuebijing Injection, Shenfu Injection, Shenmai Injection, and Shengmai Injection). AMSTAR 2 checklist showed that the methodological quality of the SR/MA ranged from moderate to very low. Item 2(prior study design) was the critical item with poor scores, and the non-critical items with poor scores were items 3(explain the selection of the study designs), items 10(report on the sources of funding), and items 16(conflicts of interest stated). In terms of PRISMA 2020, items in eight topics with complete reporting of missing>50%, including search strategy, certainty assessment, results of syntheses, certainty of evidence, registration and protocol, support, competing interests, availability of data, code and other materials. The included SR/MA involved 30 outcome indicators. Evidence quality of mortality, APACHE Ⅱ, and safety, the top three outcome indicators, was evaluated, and all of them were graded as the medium level. The lack of random allocation sequence, allocation concealment mechanism, blinding, and trial sample size was the main reason for the reduction of the evidence level. The available evidence shows that Chinese herbal injections can serve as an effective and safe adjunctive treatment for sepsis, which can reduce mortality, inhibit inflammation, improve coagulation function, and regulate immune function, tissue perfusion, and oxygenation in patients with sepsis. However, the quality of SR/MA was suboptimal, and more high-quality SR/MA is needed to provide evidence to support the efficacy and safety of Chinese herbal injections in the treatment of sepsis.

Clinical trials and evaluation of Chinese patent medicine for heart failure / 中国中药杂志

The present study systematically collected, analyzed, and evaluated randomized controlled trial(RCT) of Chinese patent medicine in the treatment of heart failure to provide references for follow-up clinical research design, guideline update, and policy formulation, and promote the improvement of clinical evidence quality. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, VIP, Wanfang, SinoMed, PubMed, and Web of Science were searched for RCTs of Chinese patent medicine in the treatment of heart failure from database inception to December 31, 2020. The di-sease type, publication time, sample size, intervention/control setting, course of treatment, evaluation indexes, and methodological quality were analyzed and evaluated. A total of 1 631 RCTs were included, including 1 622 in Chinese and 9 in English. It was first published in 1995, with the largest number of publications in 2016. There were only 56 RCTs(3.43%) with a sample size≥200. Seventy-eight types of Chinese patent medicines were involved, including 49 types of oral drugs and 29 types of injections. There were 34 intervention/control protocols, which were dominated by Chinese patent medicine+conventional treatment vs conventional treatment, accounting for 28.51%(n=465). About 94.0% of RCTs reported the course of treatment, mainly 14-56 days. The evaluation indexes were mainly physical and chemical tests and symptoms/signs, and left ventricular ejection fraction(LVEF) was the most frequently used measurement index. In enumeration indexes, clinical efficacy(response rate) was used the most frequently. Methodologically, 92.0% of the research subjects were rated as high risk of blindness. There were only 13 RCTs(0.80%) reporting registered information. It is necessary to further standardize the design, implementation, and quality control of clinical studies in order to improve the quality of evidence and avoid research waste.

Clinical trials and evaluation of Chinese patent medicine for influenza / 中国中药杂志

The clinical randomized controlled trial(RCT) of Chinese patent medicine in the treatment of influenza were reviewed and analyzed to provide basic information for clinical decision and related research. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, Wanfang, VIP, SinoMed, EMbase, PubMed, and Cochrane Library were searched for RCTs of Chinese patent medicine for influenza published from database inception to July 25, 2021. The publication time, sample size, intervention and control measures, course of treatment, outcome indicators, and methodological quality of the trials were analyzed and evaluated. Ninety-two RCTs of Chinese patent medicine for influenza published between 2005 and 2021, were included, among which 17 RCTs(18.48%) had a sample size higher than 200 and the average sample size was about 145. Twenty-seven Chinese patent medicines were involved, including twenty-one oral medicines and six injections. The Chinese patent medicines in trials reported in more than five papers included Lianhua Qingwen Capsules/Gra-nules, Tanreqing Injection, and Reduning Injection. Fourteen intervention protocols were reported, of which Chinese patent medicine+western medicine+conventional treatment vs western medicine+conventional treatment(20.65%) was the most frequently employed. Additionally, 85.87% of the RCTs reported the course of treatment, and 80.43% of the RCTs determined 3-7 d as the intervention course. Forty-five outcome indicators were extracted, which were used 434 times, including symptoms/signs, physicochemical detection, safety events, TCM symptoms/syndromes, quality of life, long-term prognosis, and economic evaluation. Symptoms/signs(61.52%) exhibited the highest frequency. Methodological problems were prevalent in the included trials. The findings reveal that there are few clinical trials on influenza treatment by Chinese patent medicine, and the methodological problems are prominent, affec-ting the reliability and practicability of the trials. In the future research, the value characteristics of Chinese patent medicine should be highlighted and the quality control in the whole process should be strengthened based on the scientific and rigorous design.

Clinical trials and evaluation of Chinese patent medicine for pneumonia / 中国中药杂志

The present study reviewed the clinical randomized controlled trials(RCTs) of Chinese patent medicine for pneumonia to provide references for clinical research, guideline development, and policy formulation, and promote the quality improvement of clinical evidence. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, Wanfang, SinoMed were searched for RCTs of Chinese patent medicine for pneumonia from database inception to December 31, 2019. A total of 1 245 RCTs were included, involving 84 Chinese patent medicines, including 45 oral medicines and 39 injections. Specifically, 85.9% of RCTs had treatment course not exceeding 14 d; 43.3% of RCTs had a sample size of more than 100 cases and 6.1% of RCTs more than 200 cases; 13 types of interventions/controls were included in the RCTs, with Chinese patent medicine + western medicine vs western medicine as the top one used(32.6%). In outcome indicators, symptoms/signs(3 285) and physicochemical detection(2 066) were the most frequently applied. In the methodological evaluation, "allocation concealment" was not clearly described or mentioned in 71.2% of RCTs, and "blinding" in 23.9% of RCTs met the normative standards. Registration and research ethics were not clearly reported. There are many methodological deficiencies in terms of design and implementation in included RCTs, which may impact the reliability and practicability of the results of RCTs. Additionally, key standards were unclear(such as disease classification methods and selection of core outcome indicators). In conclusion, RCTs should give priority to the preciseness and scientificity of the protocol, strengthening quality control of the processes and accelerating the standardized research of key links.

Clinical trials and evaluation of Chinese patent medicine for chronic obstructive pulmonary disease / 中国中药杂志

The clinical randomized controlled trials(RCTs) of Chinese patent medicine in the treatment of chronic obstructive pulmonary disease(COPD) were reviewed and analyzed to provide references for clinical research, guideline development, policy formulation, and quality improvement of clinical evidence. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, Wanfang, SinoMed, Cochrane Library, PubMed, EMbase were searched for RCTs of Chinese patent medicine for COPD as a source of clinical evidence from database inception to December 31, 2019. The publication time, sample size, intervention and control measures, course of treatment, outcome indicators, and methodological quality of the trials were analyzed and evaluated. A total of 733 RCTs of Chinese patent medicine for COPD were included, among which 228 RCTs had a sample size higher than 100, accounting for 31.1% of total RCTs. Eighty-eight Chinese patent medicines were involved, including 40 oral medicines and 48 injections. A total of 327 RCTs mentioned intervention and control measures(Chinese patent medicine + conventional treatment vs conventional treatment), accounting for 43.0%. In addition, 94.40% of the RCTs reported the course of treatment, and 53.20% of the RCTs determined 8-14 d as the intervention course. The evaluation indicators adopted were numerous, among which physicochemical indicators(70.57%) and symptoms/signs(24.35%) were the most frequently employed. The operation of allocation concealment and blinding was not standard. Registration and the procedure related to ethics were mostly missing. The results indicate that there are prominent methodological problems in the clinical trials of Chinese patent medicine in the treatment of COPD, affecting the reliability and practicability of the trials. It is necessary to further standardize the design, implementation, and quality control of clinical trials of Chinese patent medicine in the treatment of COPD, highlight the clinical value of Chinese patent medicine for COPD, and improve the quality of evidence.
