Objective To evaluate the effectiveness and safety of moxibustion for knee osteoarthritis and the methodological quality of systematic reviews(SRs).Methods SRs of moxibustion for knee osteoarthritis were retrieved from CNKI,VIP,Wanfang Data,SinoMed,PubMed,Cochrane Library,Embase and Web of Science was conducted from the establishment of the databases to February 10,2022.AMSTAR 2 was used to assess the methodological quality of SRs.The randomized controlled trials(RCTs)included in these SRs were screened and summarized according to inclusion standard.RevMan 5.4 software was used for Meta-analysis,and GRADE approach was used to assess the certainty of evidence.Results A total of 15 SRs were included.The evaluation results of the AMSTAR 2 showed that the methodological quality was very low for 14 SRs,and low for other 1 SR.A total of 36 RCTs were included.Meta-analysis results showed that compared with the non-steroidal anti-inflammatory drugs(NSAIDs),the moxibustion group had better effects on improvement of WOMAC scores[mean difference(MD)=-5.95;95%confidence interval(CI):-9.25 to-2.65;low quality],relieving pain[MD=-1.26;95%CI:-2.19 to-0.32;very low quality],and improving effective rate[risk ratio(RR)=1.16;95%CI:1.11 to 1.22;low quality].In the moxibustion group,some patients experienced blisters,and most healed in 3 days.Conclusion Moxibustion has advantages in pain reduction and improving effective rate compared with routine Western therapy for knee osteoarthritis.However,well-designed high-quality RCTs are needed for further verification.

OBJECTIVE To provide refere nce for the optimization and adjustment of the relevant policies in the field of pediatric drug in China. METHODS“Children”“pediatrics”and“drugs”were taken as the keywords to search the official websites of the State Council ，the National Health Commission ，the National Healthcare Security Administration ，the State Administration of Market Regulation and other relevant ministries and commissions ，and collect the relevant pediatric drug policies issued at the national level from January 1，2010 to December 31，2021. Content analysis method was used to summarize ，code and statistically analyze the policy tools used in the policy research documents. RESULTS A total of 39 policy documents and 327 policy tools were included in this study. According to statistics ，from 2011 to 2021，China issued national policy documents on pediatric drug use every year ，and in recent years ，the issuance of documents was relatively intensive. The main body of issuing pediatric drugs policy was the national health department and drug supervision and administration department （71.79％，28/39），and the number of documents issued by relevant ministries and commissions alone （76.92％，30/39）was significantly more than the number of documents jointly issued by multiple ministries and commissions （23.08％，9/39）. The environmental policy tools were the most widely used （64.83％，212/327），followed by s upply-oriented policy tools （30.28％，99/327），and demand-oriented policy tools were the least used （4.89％，16/327）. CONCLUSIONS The development of pediatric drug use in China is in its infancy. It is suggested that China should optimize supply-oriented policy tools，increase capital investment and the use of public health service tools ；adjust environmental policy tools ，accelerate the legislation of pediatric drugs ，and increase the proportion of incentive policy tool ；attach importance to demand-oriented policy tools ，strengthen international exchanges and the application of service outsourcing in the field of pediatric medication ；plan the use of various policy tools as a whole ，and coordinate the use proportion of three types of policy tool and their sub policy tools，so as to enhance the initiative of policy tools ，form policy synergy ，and jointly promote the development of pediatric drug use.

Syndrome differentiation and treatment is a unique mode of diagnosis in traditional Chinese medicine （TCM）. The establishment of scientific and standardized syndrome diagnosis standards is an important link to evaluate the clinical efficacy of TCM objectively and systematically， and also a prerequisite for the promotion and development of TCM to obtain international recognition. This article reviewed the basic modes and existed problems of the current syndrome diagnosis criteria， and proposed to construct a multidimensional core information set integrating the minimized core symptoms， the artificial intelligence signs， the multi-modal laboratory indicators， and multi-omics specific markers， so as to present syndrome characteristics from multiple perspectives systematically. This paper also described the basic mode， constructure， as well as the process and methodology to be adopted in the establishment of the standardized diagnostic research method. The core information set of diagnostic symptoms not only took into account the specificity of the disease， but also improved the inconsistency due to the complexity and subjectivity of the syndrome differentiation， thereby providing a methodological basis for the standardization of TCM syndrome differentiation in clinical research.

Currently， there are many difficulties in formulating recommendations of traditional Chinese medicine （TCM） clinical practice guidelines. This paper analyzed and summarized the unique or prominent difficult issues in the formulation of recommendations faced by TCM guidelines， such as experts' professional background and experience bringing about the preferance from the academic emotion， inconsistency between different academic schools making it difficult to reach consensus， lack of guiding principles of the decision weight of different dimensions for recommendations. Therefore， methodological suggestions have been put forward， including organizing parallel TCM and western medicine consensus group， improving the method of combining TCM and western medicine paradigm， attaching great importance to the evidence-based governance of academic schools， and promoting the research on different dimensions for recommendation formulation， which may provide a methodological reference for the guideline development.
