The risk factors of coronary artery disease, angiographic and procedural features are the main risk factors of restenosis after coronary artery stent implantation. In different combinations, these risk factors have different effects on coronary restenosis. The risk factors that the results of trials were more consistent include coronary lesion length, lesion vessel diameter <3 mm, ostial disease, total stent length, and number of stent. The same results of trials as stated above indicated that drug-eluting stent (sirolimus-eluting stent and paclitaxel-eluting stent), compared with bare-metal stent, significantly decreased the risk of restenosis. Compared these two drug-eluting stent, sirolimus-eluting stent was superior to paclitaxel-eluting stent on lowering the risk of restenosis. About other risk factors, e.g. age, sex, smoking, hypertension, the results of trials had inconsistent.

Objective To investigate the efficacy and safety of combined with aripiprazole to improve hyper-prolactinemia caused by antipsychotic drugs.Methods 70 patients with schizophrenia who had been treated with antipsychotic drugs for 4 weeks prior to the study were divided into the two groups by random number table method:the treatment group(35 cases)were given each additionally 2.5 mg of aripiprazole oral,one time every day.The con-trol group (35 cases)continued with no extra management.The treatment group on the basis of the original drug administered daily in combination with aripiprazole 2.5mg,the control group maintained the previous drug treatment. Serum prolactin concentrations were assayed in patients of both groups before treatment and after 4 weeks treatment. At the same time,used the positive and negative symptom scale (PANSS)to assess the state of the clinical symptoms. The side effects were evaluated by Treatment Emergent Symptom Scale(TESS).Results After combined with aripi-prazole,it demonstrated that serum prolactin level in patients of the treatment group were significantly lowered [(78.64 ±30.15)μg/L vs (35.01 ±13.99)μg/L,t=9.585,P<0.05],while those in patients of the control group had no change[(80.34 ±46.08)μg/L vs (79.94 ±43.84)μg/L,t=0.084,P>0.05].There were no significant differences between the two groups of PANSS and TESS scores(all P>0.05 ).Conclusion Combined with aripi-prazole for antipsychotic-induced hyperprolactinemia have a therapeutic effect and relatively safe.

[Objective]To discuss the operative treatments and evaluate the effects of reconstruction interlocking nail(RIN)in treating femoral shaft fractures associated with ipsilateral peritrochanteric fractures of the femur.[Method]A retrospective study was done on 37 patients with femoral shaft fractures combined with ipsilateral peritrochanteric fractures treated by RIN from September 2002 to Janurary 2009.This study involved 32 males and 5 females,with an average age of 36 years (range,24 to 69 years).Thirty-three patients had high-energy injury (26 of road accident,7 of falling from height),and 4 low-energy injury.Among them,13 patients had fractures in the upper one-third of the femoral shaft,18 in the middle one-third and 6 in the lower one-third.Six patients had open fractures (Gustilo scale Ⅰ in 1,and Ⅱ in 5).According to Garden classification for femoral neck fractures,there were 19 cases of type Ⅱ,9 cases of type Ⅲ and 2 cases of typ Ⅳ.According to AO classification for femoral intertrochanteric fractures,there were 3 cases of type A1.1,1 case of type A2.1.According to Seinsheimer classification for femoral subtrochanteric fractures,there was 1 case of type Ⅰ,and 2 cases of type ⅡA.The mean duration from injury to surgery was 3.7 days (range,4 hours to 13 days).After operation step-by-step functional rehabilitation was encouraged.[Result]The follow-up periods ranged from 14 to 38 months (average,24 months).Bony union was achieved in all patients.The average bony union time was 13 weeks for fractures of femoral shaft,14 weeks for femoral neck,12.6 weeks for intertrochanteric and 15.5 weeks for subtrochanteric fractures.Femoral head necrosis occurred in one case.No such complications as infection,loosening of nails,coxa vara,or malunion was found.According to Harris Scoring system,32 cases (86.5%)were rated as good or excellent.[Conclusion]The treatment of femoral shaft fractures associated with ipsilateral peritrochanteric fractures of the femur with RIN is a good method because of its advantages of small trauma,stable fixation,high union rate,few complications and good results.It may have fewer internal fixators.Carefully choosing suitable patients,sophisticated operation skills and active functional exercise after operation are keys to success.
