ABSTRACT
This study systematically sorted out the existing studies about Tianshu Capsules in the treatment of migraine(syndrome of blood stasis blocking collaterals, syndrome of ascendant hyperactivity of liver Yang), and conducted comprehensive clinical evaluation through "6+1" dimensions of safety, effectiveness, economy, innovation, suitability, accessibility, and characteristics of traditional Chinese medicine(TCM) to embody the advantages and characteristics and clarify the precise clinical position of Tianshu Capsules. The value of each dimension was calculated via health technology assessment, the multi-criteria decision analysis(MCDA) mo-del and CSC v2.0 software. The results were graded into four levels of A, B, C, or D from high to low. According to the available studies, Tianshu Capsules had low and controllable risks, with the safety rated as A. The drug has obvious clinical significance in the treatment of migraine(syndrome of blood stasis blocking collaterals, syndrome of ascendant hyperactivity of liver Yang), with the effectiveness rated as A. It has clear economic results, with the economy rated as B. The clinical innovation, service system innovation, and industrial innovation are all good, and thus the innovation of Tianshu Capsules is grade A. The drug can meet clinical medication demand of medical care and patients, and thus its suitability is grade A. In view of the reasonable drug price, affordability, and availability, the accessibility is grade A. The prescription originated from the Daxiong Pills recorded in the classic Comprehensive Recording of Sage-like Benefit. In clinical trials, 4 675 patients have used Tianshu Capsules, which indicates rich experience in human administration, and the characteristics of traditional Chinese medicine is grade B. The statutory drug information complies with national stan-dards, and the non-statutory information is standard and accurate. Based on the comprehensive evaluation results of various dimensions of evidence, the clinical value of Tianshu Capsules in the treatment of migraine(syndrome of blood stasis blocking collaterals and syndrome of ascendant hyperactivity of liver Yang) is class A. According to the Comprehensive Clinical Evaluation Management Guidelines of Drugs(trial version 2021) issued by the National Health Commission of the People's Republic of China, we recommend that Tianshu Capsules treating migraine can be transformed into relevant policy results for clinical medication management according to procedures.

OBJECTIVE:To optimize the ultrasonic extraction technology for Tianshu capsules. METHODS:Using the transfer rate of active ingredient ferulic acid in Ligusticum chuanxiong and gastrodin in Gastrodia elata of Tianshu capsules as investigation indexes,L9(34)orthogonal design test was adopted to investigate the effects of ethanol volume fraction,ethanol amount,extraction time and ultrasonic power on the extraction rate. Ultrasonic extraction technology for Tianshu capsules was optimized,and verifica-tion test was carried out. RESULTS:The optimized extraction technology for Tianshu capsules was as follow as 8-fold 70% etha-nol,extracting twice under 350 W,extracting 1.5 h every time. Results of verification test showed the average transfer rate was 94.06% for ferulic acid(RSD=0.18%,n=3)and 95.02% for gastrodin(0.47%,n=3). CONCLUSIONS:The optimized tech-nology is rapid,simple,stable and feasible,and can be used for extracting the active ingredients in Tianshu capsules.
