OBJECTIVE:To provide reference for promoting the further development of pharmaceutical service in chain phar-macies and the regulation of related departments. METHODS:Field investigation and questionnaire survey were used to investigate the basic situation of pharmaceutical care in 5 chain pharmacies in Chengdu city and analyze the results. RESULTS:In terms of core service,it showed that 2 pharmacies had no suspension of pharmacists license and the pharmacist was not on-the-job;there was significant difference in the medication guidance frequency of pharmacists in those pharmacies(P<0.05);more than 50% sur-veyed consumers received medication guidance when buying drugs in pharmacy B,C and E. In terms of perceived service,3 phar-macies existed illegal drug advertising and 3 existed illegal promotion;drug partitions of all pharmacies were good;service archive material showed best in pharmacy C and worst in pharmacy D;in service advisory zone setting,setting of independent advisory zone was worse. In terms of extended service,5 pharmacies had different preferential ways for memberships except for the prefer-ence in membership day;the unbundling service in those pharmacies was worse,and no pharmacies had no less than 10 unbun-dling varieties. CONCLUSIONS:Pharmaceutical service in chain pharmacies in Chengdu city is barely satisfactory. Pharmacy should strengthen the assessment and management of pharmacists and improve pharmaceutical service,and regulatory authorities strengthen the supervision of advertising and promotion of drugs. What’s more,it is suggested to establish cloud supervision plat-form with the internet information technology,carry out remote service and cloud service and strengthen brand marketing service on the internet to improve the pharmaceutical service levels in chain pharmacies.

OBJECTIVE:To improve the automation of hospital pharmaceutical warehouse management by using Visual Basic for Applications (VBA) language so as to improve work efficiency. METHODS:Through editing VBA language of Microsoft of-fice software,the experience of our hospital was swmmarized,such as letting the computer automatically sort,split and encrypt, pharmaceutical email and track purehase plan. RESULTS & CONCLUSIONS:By adopting VBA programming,our hospital has re-alized automatic splitting of the pharmaceutical purchase plan,sending pharmaceutical shortage warning and automatic warning doc-ument management. Pharmaceutical purchase plans are sent faster and drug distribution to our hospital is becoming more timely. The management of document that have a period of validity is becoming more intelligent. Massive manpower and resoure are saved,and the work efficiency is greatly improved. New ideas and methods for smart warehouse management are provided.

OBJECTIVE:To provide reference for improving the pharmaceutical care of chain drug stores.METHODS:By convenience sampling,questionnaire survey about pharmaceutical care of drug stores was conducted among the customers in 5 chain drug stores (selecting each one branch drug store with certain scale) from Chengdu.The data were analyzed statistically.RESULTS:A total of 413 questionnaires were issued,of which 400 were valid,with effective recovery rate of 96.9％.Only 25.5 ％ respondents could identify the licensed pharmacist;higher educated respondents and respondents with academic background of medicine were more likely to make distinction (P＜0.05).The respondents who had often received the service of medication guidance,the service of recommending same effect medicine with low price and the service of medication instruction was only 45.5％,19.0％ and 48.3％ respectively,5.3％,13.0％ and 10.8％ of those who had never received such services.Respondents' satisfaction with the general service staff (64.0％) was much higher than with licensed pharmacist (34.3％).Respondents believed that the three most important pharmaceutical care were medication guidance,helping boiling TCM and free health test.CONCLUSIONS:Consumers can not clearly distinguish the licensed pharmacist in drug stores.The situation that consumers can get major items of pharmaceutical care is still unsatisfactory.Consumers are less satisfied with licensed pharmacists,but their attention to medication guidance services reflects their strong awareness of medication safety.

Tacrolimus (FK506) is a 23-membered macrolide with immunosuppressant activity that is widely used clinically for treating the rejection after organ transplantation. The research on tacrolimus production was mainly focused on biosynthesis methods, within which there are still some bottlenecks. This review summarizes the progress made in tacrolimus biosynthesis via modification of metabolic pathways and control of fermentation process, with the hope to address the technical bottlenecks for tacrolimus biosynthesis and improve tacrolimus production by fermentation engineering and metabolic engineering.

OBJECTIVE To systematically evaluate the efficacy and safety of vonoprazan in the treatment of gastroesophageal reflux disease， and to provide evidence-based reference for clinical drug use. METHODS Randomized controlled trials （RCTs） about vonoprazan （trial group） versus placebo or proton pump inhibitor （control group） were searched in PubMed， the Cochrane Library， Web of Science， CNKI， Wanfang， VIP and CBM databases from the inception to June， 2022. After literature screening and data extraction， the qualities of included literature were evaluated with bias assessment tool recommended by Cochrane system evaluator manual 5.1.0. Meta-analysis， sensitivity analysis and publication bias analysis were conducted by using RevMan 5.4 software. RESULTS A total of 9 RCTs were included， involving 1 882 patients. The results of meta-analysis showed that： total response rate [OR＝1.94，95%CI（1.45，2.58），P＜0.000 01]， cure rate [OR＝2.27，95%CI（1.33，3.86），P＝0.003] and remission rate [OR＝1.81，95%CI（1.28， 2.55）， P＝0.000 7] of trial group were significantly higher than control group； there was no significant difference in the incidence of adverse drug events， diarrhea， nasopharyngitis， upper respiratory tract infection and alkaline phosphatase elevation between two groups （P＞0.05）. The results of subgroup analysis showed that cure rate of trial group was significantly higher than control group at 2 weeks of treatment （P＜0.05）； at 4 and 8 weeks of treatment， there was no significant difference in the cure rate between two groups （P＞0.05）. There was no statistically significant difference in the cure rate between two groups at 2， 4 and 8 weeks of treatment among the patients with Los Angeles grade A/B （P＞0.05）； among the patients with Los Angeles grade C/D， the cure rate of patients in the trial group was significantly higher than control group at 2， 4 and 8 weeks of treatment （P＜0.05）. The results of sensitivity analysis and publication bias analysis showed that the results of this study were robust and the possibility of publication bias was small. CONCLUSIONS Vonoprazan has a considerable effectiveness and safety in the treatment of gastroesophageal reflux disease.
