Objective To investigate the treatment of proximal femoral nail antirotation (PFNA) in pertrochanteric hip fractures with unstable lateral-wall.Methods Thirty-two cases were included from the April 2009 to May 2011.Recorded operation period,blood loss volume,and complications and evaluated the effect of the methods.Arrange referral at 6 weeks,3 months,6 months,12 months respectively after operation,to check limb function and conventional camera hips,lateral X-ray film.Postoperative functional evaluation using the Harris hip score.Measure the last follow-up neck shaft angle and compare with postoperative's.Results The average operation period was (60-190) min,average was (80 ± 5) min ; blood loss volume was (90-250)ml,average was (120 ± 9) ml ; Average hospital periods was (15 ± 7) days; weight loading time was (6.3 ± 1.2)weeks after surgery and average time of union of fracture was 3.6 months.All patients obtained union of fracture without complications such as varus,internal fixation cutting out.Conclusion PFNA was proved to be an effective way for treating unstable lateral-wall of pertrochanteric hip fractures due to its advantages of stable fixation,minor trauma,less complications.

Objective To compare the clinical outcomes between proximal femoral nail antirotation (PFNA) combined with risedronate sodium and isolated PFNA for the treatment of intertrochanteric fractures in elderly patients.Methods Clinical data of 62 elderly patients with intertrochanteric fracture from January 2011 to April 2013 were prospectively studied.Patients were randomly divided into two treatment groups:risedronate sodium group (the combined PFNA and risedronate) and control group (isolated PFNA).According to AO classification,32 patients in risedronate sodium group (15 males and 17 females,with an average age of 78 years) were divided into type A1 (n=10),type A2 (n=18) and type A3 (n=4).30 patients in control group (13 males and 17 females,with an average age of 77.5 years) were divided into type A1 (n=9),type A2 (n=16) and type A3 (n=5).Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry before and 1 year after operation.The hip joint function was assessed by Harris hip score.Complications and subsequent fragility fractures were evaluated postoperatively.Results 60 patients (30 patients in risedronate sodium group and 30 patients in control group) were followed up for at least one year.All fractures were healed at 6 months after surgery.No significant difference was found between the two groups in BMD in contra-lateral hip before treatment [(-2.58±0.41)kg/m2 vs.(-2.56±0.36)kg/m2,P＞0.05].BMD in contra-lateral hip had significant difference between the risedronate sodium and control groups one year after surgery [(-0.66±0.37)kg/m2 vs.(-1.13 ±0.28)kg/m2,P=0.000].There was no significant difference between the two groups in Harris hip score (P=0.238).During the follow-up,no patient in risedronate group suffered from subsequent fragility fracture after surgery,while lumbar compression fracture occurred in 1 case,distal radius fracture occurred in 1 case,the contralateral hip fractures occurred in 2 cases,postoperatively.Conclusions PFNA treatment combined with risedronate sodium can effectively improve BMD and reduce the risk for refracture,and has a good effect on intertrochanteric fracture in elderly patients.

The changes of the dietary composition of Shanghai population from 1950 to 1985 were investigated and the relationship between the dietary composition and the mortality of diseases of the population was analysed with retrospective method. The results showed that the amount of consumption of grain was decreased but that of animal foods increased (except that around 1960) year after year during the past 35 years. The consumption of meat and eggs in 1985 was 2.8 and 4.9 times , higher than that in 1950 respectively. The intake of carbohydrates was decreased but- that of fat increased year by year. The ratio of polyunsaturated fat to saturated fats (P/S) was decreased and there was a trend of excess intake of fat. The mortalities from malignant tumours, cardiovascular and cerebrovascular diseases were increased year by year, which correlated strongly with the consumption of dietary saturated fat. On the other hand the intake of protein, calcium and riboflavm was lower. Therefore, the dietary composition of Shanghai population was imperatively adjusted.

Objective To investigate the role of activated T lymphocytes in the pathogenesis and effect of CD95 and bcl 2 expression on the development of alopecia areata. Methods The lymphocytes were isolated from the peripheral blood of the patients. Then CD4 +, CD8 +,and/or CD95 and bcl 2 positive lymphocytes were sorted out by flow cytometry . Results In the active stage of the disease, CD4 + lymphocytes decreased while CD8 + lymphocytes increased significantly. At the same time, the expression of bcl 2 was much more frequently detected in CD8 + lymphocytes than in CD4 +lymphocytes. CD95 expression was also increased markedly in T lymphocytes. Conclusions Down regulation of bcl 2 leads to the decrease in number of CD4 + lymphocytes. Meanwhile, CD8 + lymphocytes increased duo to the over expression of bcl 2. As a result , the ratio of CD4 + to CD8 +lymphocytes has dropped markedly and the cytotoxic effect of CD8 +lymphocytes on the hair follicles is enhanced. On the other hand, over expression of CD95 in T lymphocytes triggers cell apoptosis in the hair follicles. Both effects promote the development of alopecia areata . [
