OBJECTIVE: To provide reference for reducing disadvantageous drug-drug interaction(DDI)and avoiding adverse drug event(ADE). METHODS: The patients aged more than 65 were selected from cardiovascular department in our hospital dur-ing Jun. 2015-Mar. 2016. The influential factors for potential DDI(PDDI)-induced ADE were analyzed. The relationship of related factors with PDDI-induced ADE was analyzed by multivariate Logistic regression analysis. RESULTS:A total of 328 patients were included,involving 257 PDDI patients,and totally 452 cases of PDDI (including 247 cases of mild PDDI,149 cases of general PDDI and 56 cases of severe PDDI). The age,the number of drugs used simultaneously,Ccr and liver function (Child-Pugh score)were related to the occurrence of PDDI-induced ADE(P<0.01). CONCLUSIONS:For PDDI-induced ADE,the risk evalua-tion can be conducted for a series of factors,including age,the number of drugs used simultaneously,Ccr and liver function. For high-risk patients,intervene should be conducted in advance to reduce the risk of ADE.

OBJECTIVE:To establish the method for the content determination of2,3,5,4'—tetrahydro-xystilbene—2—O—?—D—glucoside in Yangxueshengfa capsules by RP-HPLC.METHODS:Alltima-C 18 was used as the chromatographic column;the acetonitrile-water(15∶85)was taken as the mobile phase with flow speed at1.0ml/min and detection wave?length at320nm.RESULTS:In the range of0.45?g～2.26?g,2,3,5,4'—tetrahydro-xystilbene—2—O—?—D—glucoseide were in direct proportion to the peak area value(r=0.9996),the mean recovery rate was98.32%(RSD=1.58%,n=6). CONCLUSION:This method was simple,convenient and accurate,which can be used for the content determination and the quality control of Yangxueshengfa capsules.

Objective: To study the optimum extraction condition of effective composition in Rhizoma Alpiniae Officinarum by CO 2 supercritical fluid extraction. Methods: CO 2 supercritical fluid extraction condition was selected by uniform design. The extraction pressure, extraction temperature, analytic pressure, analytic temperature were four factors in the experiment. Seven levels of each factor were selected.Results: The optimum extraction condition in SFE was: extraction pressure at 30MPa, extraction temperature at 32?C , analytic pressure at 6MPa, analytic temperature at 36?C . Conclusion: The method is simple, selective and efficient.

OBJECTIVE:To compare the clinical efficacy and safety of amiodarone and propafenone in the treatment of chron-ic atrial fibrillation cardioversion. METHODS:60 patients with chronic atrial fibrillation cardioversion were randomly divided into propafenone group and amiodarone group. All patients were given conventional treatment,including treating primary disease,con-trolling symptoms,orally giving aspirin,intravenous infusion of GIK,monitoring heart rate,QT interval,P-R interval,QRS time,serum potassium and serum magnesium,etc. On this basis,propafenone group was orally given propafenone 450 mg for con-tinuous 3 months,3 times a day,and then the dose was decreased to 300 mg to maintain the sinus rhythm;amiodarone group was orally given amiodarone 200 mg for continuous 7 d a month,twice a day,and then the dose was decreased to 200 mg or 100 mg to maintain the sinus rhythm. The clinic data in 2 groups was observed,including clinical efficacy,simple drug cardioversion,elec-trical cardioversion,electrical cardioversion power,hospitalization time and incidence of adverse reactions,and the recurrence rate in 48 months was followed up. RESULTS:There were no significant differences in the clinical efficacy,simple drug cardiover-sion,electrical cardioversion,electrical cardioversion power,hospitalization time,incidence of adverse reactions and recurrence rate between 2 groups(P>0.05). CONCLUSIONS:Based on the conventinal treatment,amiodarone and propafenone have similar clinical efficacy and safety in the treatment of chronic atrial fibrillation cardioversion,and both of them can be used as the conven-tional drugs for treating chronic atrial fibrillation cardioversion.

OBJECTIVE To analyze the medication reconciliation for the inpatients in cardiovascular medicine department ，to provide reference for the establishment of working mode of clinical pharmacists in the department of cardiovascular medicine and to provide a basis for clinical pharmacists and community pharmacists developing pharmaceutical care for patients after transfering to community health center. METHODS From October 2020 to September 2021，newly admitted or newly transferred inpatients with chronic disease were selected from Shiyan People ’s Hospital of Shenzhen Bao ’an District. Medication reconciliation was conducted by clinical pharmacists after pharmaceutical consultation. According to the Pharmaceutical Care Network Europe （PCNE） classification system V 9.1，the existing drug-related problems （DRPs）were classified and summarized. The effectiveness and safety evaluation，medication education and other measures were provided ，and the acceptance of intervention was analyzed at the same time. RESULTS A total of 100 patients were included ，including 54 males and 46 females. The average age was （60.21±9.69） years，the average number of chronic diseases was （2.84±0.83），and the median number of drugs was 5.00. Among them ，110 treatment drug deviations were found in 74 patients，involving 10 categories and 61 drugs. Top three drugs in the list of accumulative drug deviation were cardiovascular system drugs （35 deviations），digestive medicine drugs （16 deviations）and endocrine system drugs （15 deviations）. The above treatment drug deviation may cause 122 DRPs， mainly “treatment effectiveness”problems（74 DRPs），and the causes were “inappropriate medication time ormedication interval ”（32 DRPs）， followed by “inappropriate drug combination ”（10 DRPs）. Interventions to DRPs mainly concentrated on patient level ，drug level （58）and doctor level （58），155 of which （84.70％）were fully accepted and implemented. CONCLUSIONS Some patients have a weak awareness of medications according to doctor ’s advice；drug reconciliation led by clinical pharma- cists at admission can fully understand the potential drug problems of patients ，and help doctors improve the drug compliance of patients and ensure their medication safety .
