The roles of pharmacists in clinical trials including GCP training , drug administration , evaluation of drug safety issues in clinical trials and regimen design etc were discussed and prospected in the paper .The roles of pharmacists are decisive , and they will play more important roles in clinical trials .

Objective To analyze of related factors in affecting condylar buttress plate (CBP) surgical treatment of distal femoral fractures.Methods One hundred patients with distal femoral fractures were grouped according to eight related factors (gender,age,fracture type,fracture classification,surgical time,reset quality,whether bone graft and plaster braking),respectively.Operative efficacy was scored by the Neer knee functional score table,and score ≥ 72 was excellent,while ＜ 72 was good.Eight related factors were carried out single factor analysis with x2 test to compare the operative efficacy of each group,then the related factors with single factor analysis result of P＜0.05 were put in Logistic multifactor regression analysis,in order to clarify the independent risk factors for CBP treatment of distal femoral fractures.Results There was no significant difference (P＞0.05) in the operative efficacy between male and female group,open fracture and closed fracture group.The difference between youth,middle-aged and elderly group,type A and type C fracture group was statistically significant (P＜0.05).The operative efficacy of patients got surgery within 7 d was obviously better than those who got surgery 7 d later (P＜0.05).The operative efficacy of patients who had no intraoperative bone graft was better than those who had bone graft (P＜0.05).The operative efficacy of satisfactory reset group and none plaster braking group was better than that of unsatisfied reset group and plaster braking group (P＜0.05),respectively.Conclusions Age,fracture type and reset quality are CBP therapy independent risk factors for the efficacy of operation for patients with distal femoral fractures,which will provide some reference for improving the operative efficacy of CBP operation in treatment of distal femoral fractures.
