Objective To evaluate the clinical results using modified Richards nail treating femoral intertrochanteric comminuted fractures.Methods From March 2002 to March 2005,69 patients suffered from femoral intertrochanteric comminuted fractures belong to Evan Ⅲ type or Ⅳ type were randomly divided into experimental group and control group.The experimental group was treated with modified Richards nail,including 34 patients,18 males and 16 females.The patients were from 61 to 78 years old,and the mean age was 67.5 years old.In this group,21 patients were involved in left femoral intertrochanteric comminuted fractures,13 patients were involved in right.The pattern of the fractures included EvanⅢ type in 24 cases and Ⅳ type in 10 cases.The control group including 35 patients was treated with DHS,and there were 19 males and 16 females with an average age of 65.9 years(ranged 61 to 80 years).In this group,19 patients were involved in left femoral intertrochanteric comminuted fractures,16 patients were involved in right.The pattern of the fractures included EvanⅢ type in 25 cases and Ⅳ type in 10 cases.Results The experimental group were followed-up 9-23 months with a mean of 11.60?3.78 months.The control group were followed-up 9-24 months with a mean of 11.40?4.12 months.In experimental group,the average fracture healing time was 3.65?0.97 months.While in the control group,the average fracture healing time was 4.32?1.38 months.In experimental group,the leg length measured at the 9th month post-operatively was averagely(0.82?0.36)cm shorter in the diseased side than in the healthy side,while in control group the leg length was averagely(1.08?0.51)cm shorter.There was significant difference between two groups.Compared to the control group,the curative effect was better in the experimental group.Conclusion Treating femoral intertrochanteric comminuted fractures with the modified Richards nail shows a good result,which can effectively diminish the non-union or mal-union of the fractures.

Objective To study the clinical features,the diagnosis and treatment of left renal entrapment syndrome. Methods Four male patients with left renal entrapment syndrome were reported.Their age ranged from 16 to 22 years.The clinical features were characterized by recurrent episodes of gross hematuria,and 1 case had left varicocele concomitantly.Cystoscopy showed hematuria from the left ureter orifice.B-ultrasonography and CT scan showed that the left vein was clearly compressed at the included angle of abdominal aorta and superior mesenteric artery and the proximal vein was dilated in all the 4 patients.The characteristics of onset and imaging, and treatment of left renal entrapment syndrome were reviewed and discussed with the relevant literature. Results The diagnosis was established in the 4 cases based on B-ultrasonography and CT scan.Left renal vein reconstruction was performed on them.The patients were cured and discharged,with renal vein outflow being normal and no hematuria occurring.At 6 and 9 months after operation,CT and ultrasonography showed that the kidney contour was normal,the reconstructed veins were patent,and the routine urine test results were normal. Conclusions Left renal entrapment syndrome clinically results in high pressure of renal vein,hematuria and left varicocele.Autotransplantation of the left renal vein is an effective treatment option.

Objective To review the diagnosis and treatment of primary gallbladder carcinoma in patients older than 70 years.Method The clinical data of 48 patients older than 70 years with primary gallbladder carcinoma treated in our hospital from 2003 to 2010 were retrospectively analyzed.Results The preoperative diagnostic rate was 60.4％.Of 48 patients with primary gallbladder carcinoma,9 received cholecystectomy,18 radical resection,7 extended radical resection,8 palliative operation,while the remaining 6 received biopsy because of metastasis. The 3-year survival rate was 20.8％ and the 5-year survival rate was 8.3％.Conclusions Regular B-ultrasonography,CT-scan and MRI are suggested for elderly patients with chronic diseases of the gallbladder.Radical resection is recommended if clinically possible. Chinese traditional medicine given postoperatively improved the prognosis.

AIM: To investigate the effect of testosterone with varied concentrations on the fibr inolysis activity of HUVEC and its mechanism. METHODS: Human umbilical vein endothelial cells (HUVEC) were cul tured as recommended. After confluence, the cultures were treated with testoster one(3 ?10 -10, 3?10 -9, 3?10 -8,3?10 -6, 3?10 -5 m ol/L) , and the control confluent cells were cultured in the same medium witho ut steroid. MTT experiment was repeated for 72 hours to investigate each groups' cell proliferation. The tPA and PAI-1 antigen levels were assayed with ELISA K its. Then with HUVEC incubated in androgen receptor antagonist (flutamide) 3 hou rs previously, the experiment was repeated. RESULTS: Testosterone at physiologic or lower concentrations (3 ?10 -10 to 3?10 -8 mol/L ) stimulated the secretion of tPA by HUVEC (P

Objective To investigate the effect on the menstrual patterns and sexual quality of life of patients with adenomyosis after treated with Mirena IUD.Methods56 patients with adenomyosis who were treated with Mirena IUD were recruited from August 2009 to December 2009.We used Menstrual blood loss chart method,Dysmenorrhea score method and Brief Index of Sexual Function for Women (BISF-W) to evaluate the menstrual pattern,the volume of uterus and sexual quality after1,3,6,9,12 months.{Results53 patients were followed up,the rate was 94.6%.The condition of 56 patients became better after treated with Mirena for 3,6,9,12 months,dysmenorrhea[Placed before:(3.15±0.91)points;After placing:(1.41±0.51)points,(0.22±0.09)points,(0.07±0.01)points,0 points]and menstrual quantity[Placed before:(12.0±57.5)points;After placing:(71±23.1)points,(29±19.4)points,(18±10.5)points,(10±4.7)points]were both reduced(P＜0.05),the symptoms were not significantly improved after 1 month(P＞0.05).D2 indicators was significantly improved after 3 months of treatment (P＜0.05),sexual function was also improved after 6 months(P＜0.05～0.01).ConclusionsMirena IUD has a good effect on the menstrual pattern and sexual function for patients with adenomyosis.

AIM: To investigate the action of testosterone on atherosclerosis in a rabbit model. METHODS: 37 male cholesterol-fed rabbits were divided into five groups: castration group: castrated rabbits without exogenous testosterone administration; testosterone Ⅰ group: castrated rabbits with exogenous testosterone 0.25 mg?kg -1?d -1; testosterone Ⅱ group: castrated rabbits with exogenous testosterone 2.5 mg?kg -1?d -1; testosterone Ⅲ group: castrated rabbits with exogenous testosterone 12.5 mg?kg -1?d -1. The sham operation group was also set. Three months later, the levels of testosterone, blood lipids (including TG, HDL-C, LDL-C), PAI activity, nitric oxide (NO) content, endothelin (ET), angiotensin Ⅱ (AngⅡ) in blood were detected. RESULTS: It showed that testosterone in castration group was the lowest. There was no significant difference of TG or LDL-C between castration group and the other four groups. HDL-C in castration group was lower than that in other four groups. NO content of castration group was lower than that in others, but PAI activity, ET and AngⅡ concentration were higher than that in other groups. CONCLUSION: Testosterone is a protective factor against atherosclerosis in male rabbits.

Objective To observe the effect of bilateral movement training on upper extremities dysfunction in stroke patients in convalescent phase. Methods 52 patients with hemiplegia were randomly divided into treatment group (n=26) and control group (n=26). The treatment group accepted bilateral upper extremities movement training, and the control group accepted routine neurodevelopment training mainly with affected upper extremities, for 6 weeks. They were assessed with Fugl-Meyer Assessment upper-extremity section (FMA-UE) and modified Barthel Index (MBI) before and after treatment. Results The FMA-UE and MBI scores improved in both groups after treatment (P<0.01), and improved more in the treatment group than in the control group (P<0.001). Conclusion Bilateral movement training may improve upper extremity function and activities of daily living more effectively for stroke patients in convalescent phase.
