According to the polarity of different components in Sanpian Decoction, two fingerprints were established. Then the substance benchmark freeze-dried powder of 15 batches of Sanpian Decoction was prepared, followed by the determination of the fingerprints, index component content, and dry extract rates, the identification of attribution of characteristic peaks, and the calculation of similarities between these fingerprints and the reference(R), the content and transfer rate ranges of ferulic acid, sinapine thiocyanate, liquiritin, and glycyrrhizic acid, and the dry extract rate range. The results showed that the similarities of 15 batches of the substance benchmark fingerprints with R were all greater than 0.900.Further summarization of the characteristic peaks revealed that there were a total of 20 characteristic peaks in fingerprint 1, among which, eight were from Sinapis Semen, four from Paeoniae Radix Alba, six from Chuanxiong Rhizoma, and two from Glycyrrhizae Radix et Rhizoma. A total of 16 characteristic peaks were observed in fingerprint 2, including one from Sinapis Semen, three from Paeoniae Radix Alba, eight from Chuanxiong Rhizoma, and four from Glycyrrhizae Radix et Rhizoma. The average dry extract rate of 15 batches of substance benchmarks was 18.25%, with a dry extract rate range of 16.28%-20.76%. The index component content and transfer rate ranges were listed as follows: 0.15%-0.18% and 38.81%-58.05% for ferulic acid; 0.26%-0.42% and 36.51%-51.02% for sinapine thiocyanate; 0.09%-0.15% and 48.80%-76.61% for liquiritin; 0.13%-0.24% and 23.45%-35.61% for glycyrrhizic acid. The fingerprint, dry extract rate, and index component content determination was combined for analyzing the quality value transfer of substance benchmarks in the classic prescription Sanpian Decoction.The established quality evaluation method for the substance benchmarks was stable and feasible, which has provided a basis for the quality control of Sanpian Decoction and the follow-up development of related preparations.

By preparing 15 batches of lyophilized powder samples of substance benchmark in Houpo Wenzhong Decoction,the fingerprint,index component content and extract rate were determined,and the characteristic peaks,the range of similarity with the reference map,the content range and transfer rate range of magnolol,hesperidin,glycyrrhizic acid and pinocembrin,the extract rate range and the change range were clarified. The results showed that the similarity between the fingerprint of substance benchmark and the reference map R generated from the 15 batches of substance benchmark samples was higher than 0. 90. The assignment of the characteristic peaks in the full prescription's fingerprint of the herbs except Poria cocos was clarified. Nineteen characteristic peaks were assigned,and 12 characteristic peaks were assigned by the reference substance,of which 4 were from Magnolia ocinalis Cortex,5 from Exocarpium Citri Rubrum,2 from Radix aucklandiae,3 from Glycyrrhiza Radix et Rhizoma,4 from Semen Alpiniae Katsumadai,and one from Rhizoma Zingiberis and Zingiber officinale Roscoe. The index component content range and transfer rate range were 0. 80%-1. 14% and 20. 25%-39. 61% for hesperidin,0. 49%-0. 79% and 23. 09%-33. 87%for glycyrrhizic acid,0. 03%-0. 07% and 3. 55%-10. 09% for pinocembrin,0. 15%-0. 38% and 8. 08%-24. 35% for magnolol. The extract rate range and the change range were22. 60%-25. 57% and 12. 67%-23. 68% respectively. In this study,we introduced the concepts of index component content,fingerprint,extract rate,explored the transfer relation of quality value transmitting of substance benchmark in Houpo Wenzhong Decoction,and initially established the quality standard of Houpo Wenzhong Decoction,all of which would provide ideas for the development and research of similar prescriptions.

OBJECTIVES@#To investigate the effectiveness and safety of Xingnaojing Injection (XNJ, ) compared with naloxone for the treatment of acute alcohol intoxication (AAI), and provide the latest evidence through evidence-based approach.@*METHODS@#Seven electro-databases including PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure Databases, Chinese Biomedical Literature Database, Chinese Science and Technology Periodical Database (VIP) and Wanfang Database were searched from the inception to January 2018. Randomized controlled trials (RCTs) comparing XNJ with naloxone for patients with AAI and reporting at least one of the below outcomes were included: patients' conscious recovery time, stay length in emergency department, disappearance time of the ataxia symptom, the severity of the symptoms, the blood alcohol content as well as the adverse events. Methodological quality of included trials was assessed using the risk of bias tool which recommended by the Cochrane Collaboration. Meta-analysis was conducted by Review Manager 5.3 software.@*RESULTS@#Totally 141 trials with 13,901 patients were included in this review, all of them were assessed as unclear or high risk of bias. Results showed that on the basis of routine therapy, standard dose XNJ (10-20 mL) may have similar results with naloxone on the recovery time of consciousness (MD 12 min, 95% CI 7.2-17.4 min) and disappearance time of symptoms (MD 6 min, 95% CI-13.8-25.8 min) for patients with AAI. Larger dose of XNJ Injection (21-40 mL) may speed up the time (almost 1 h earlier). Combination of XNJ and naloxone seemed superior to the naloxone alone for all the relevant outcomes. The average difference of time in consciousness recovery was 2 h and the number of AAI patients whose consciousness recovery within 1 h was above 50% the combination group than in the control group (RR 1.42, 95% CI 1.29 to 1.56). No severe adverse events or adverse reactions of XNJ were reported in the included trials.@*CONCLUSIONS@#Low quality of evidence showed XNJ may have equal effect as naloxone and may achieve better effect as add-on intervention with naloxone for patients with AAI. We failed to evaluate the safety of XNJ Injection due to the insufficient evidence in this review. Registration number. in PROSPERO (No. CRD42018087804).
