OBJECTIVE： To standardize the management of temporary drug purchase， and to provide reference for drug selection in Hospital Pharmaceutical Administration and Drug Treatment Committee （Pharmaceutical Association）. METHODS： Clinical pharmacists set up drug quantitative scoring table according to the 10 attributes of drugs as effectiveness， safety， economy， etc. 15 temporary purchased drugs submitted by departments in Oct. 2018 were graded according to the rules of the scoring table， and the evaluation results were fed back to Pharmaceutical Association. A retrospective evaluation of 20 temporary purchased drugs which were discussed at the Pharmaceutical Association from Jul. to Sept. 2018 was made according to previous approval model without using drug quantitative scoring table. The effect of pre-intervention was evaluated after using drug quantitative scoring table. RESULTS： Among 15 temporary purchased drugs， 2 of them scored below 60， and the unqualified rate was 13.3％. It suggested that 2 drugs could not be discussed at the meeting. Among 20 temporary purchased drugs that have been discussed at the meeting， 9 of them scored below 60， with the unqualified rate of 45.0％， suggesting that 9 drugs may have wasted the workload of the Pharmaceutical Association. CONCLUSIONS： Drug quantitative scoring table can play a pre-intervention role in the scoring of temporary purchased drugs to a certain extent. At the same time， the table can also be used as a relevant reference for hospital drug evaluation. It is helpful to optimize hospital drug use list and improve the level of rational drug use in clinic.

OBJECTIVE：To promote the safe use of severe ADR-inducing drugs in special population in our hospital. METHODS：According to detailed quantitative scoring rules of Quick Guide for Drug Evaluation and Selection in Chinese Medical Institutions，comprehensive evaluation database of drugs in our hospital was established. Drugs with ADR rating or ADE general terminology standard rating of 1，2，3 and 4 under the "safety" dimension were obtained from the database. According to the difference of the incidence of ADR ，4 kinds of severe ADR-inducing drugs ，such as very common （incidence≥10％），common （incidence 1％-＜10％），occasional（incidence 0.1％-＜1％）and rare （incidence ＜0.1％），were obtained. According to the quantitative scores of these 4 kinds of drugs in six special groups ，such as children ，pregnant women ，lactating women ，the elderly，patients with abnormal liver function ，and patients with abnormal kidney function ，the feasibility for special population to use drugs that cause severe ADR was analyzed. RESULTS ：Among 1 172 chemical drugs in drug comprehensive evaluation database of our hospital ，18，73，61，and 357 kinds can cause very common ，common，occasional and rare severe ADR ， respectively. Among them ，the incidence of severe ADR caused by tumor drugs was high ，so it was necessary to pay close attention to the use of tumor drugs in special populations. Totally 173 kinds of drugs were prohibited for children because the instructions clearly showed organ toxicity ，cytotoxicity and there were no guidelines recommending their use in children ，so the clinical medication should be used with extraordinary caution. There were 278 and 228 drugs prohibited for pregnant women and lactating women，which were prohibited for pregnant or lactating period due to embryonic toxicity and reproductive toxicity. There were 13 prohibited drugs for the elderly ，most of which were specialized drugs. Five kinds of drugs were prohibited in patients with abnormal liver function and seven were prohibited in patients with abnormal kidney function ，most of which were tumor drugs with strong hepatorenal toxicity. CONCLUSIONS ：Established quantitative score system can provide effective guidance for the safe use of severe ADR-inducing drugs among 6 special populations as children ，pregant women ，lactating women ，the elderly ，the patients with abnormal liver function and the patients with renal

OBJECTIVE To systematically evaluate the effectiveness of different treatment regimens as first-line treatment for metastatic urothelial carcinoma （UC） using a network meta-analysis （NMA） approach. METHODS Electronic databases including PubMed， the Cochrane Library， Embase， Wanfang Data， CNKI， and VIP were searched for randomized controlled clinical trials （RCTs） on first-line treatment for metastatic UC from January 1， 2010 to January 31， 2024. After literature screening and data extraction， a risk of bias assessment of included studies was conducted. R software （version 4.3.2） was used to perform the NMA. RESULTS A total of 11 RCTs involving 14 treatment interventions were included. No significant differences were noted in objective response rate among groups， with the combination of pembrolizumab， gemcitabine and cisplatin having the highest probability of ranking first. Regarding progression-free survival （PFS） and overall survival （OS）， no significant differences were observed among groups， while enfortumab vedotin combined with pembrolizumab showed a trend towards better PFS extension compared to gemcitabine combined with cisplatin [HR＝0.45， 95%CI（0.20，1.06）， P＝0.049]， and it had the highest probability of ranking first in both PFS and OS. CONCLUSIONS The combination of enfortumab vedotin and pembrolizumab may have an advantage in prolonging survival in the first-line treatments for metastatic UC.
