OBJECTIVETo evaluate the treatment effect of three and four-part fractures of proximal humerus in elder patients using indirect reduction combined with locking proximal humeral plate (LPHP) fixation.

METHODSFrom November 2004 to May 2008, 24 cases of proximal humeral three and four-part fracture were treated with percutaneous plate fixation using LPHP included 6 males and 18 females with an average age of 70 years old ranging from 55 to 88 years. The surgery was performed through antrolateral transdeoltoid approach. After extra articular capsule indirect reduction, the plate was inserted through the incision, and then an incision was made distal to previous incision to expose distal plate. The proximal fragments were fixed with 4 to 6 screws, and distal fragments were fixed with 3 screws. Shoulder exercises were performed at the 2nd to 3rd day after operation. Two weeks after operation, active shoulder exercise was done, which was gradually intensified 3 weeks after operation. The functional outcomes of the shoulder were assessed according to Constant score.

RESULTSAll the fractures united clinically and radiologically. The mean healing time was 10.5 weeks (8 to 21 weeks). The mean Constant score was 81.6 points (49 to 92 points). A total of 20 patients had excellent or satisfactory result, with only one scored as poor.

CONCLUSIONThe technique of extra articular capsule indirect reduction combined LPHP internal fixation has the advantages of stable, easy to operate, less vascular damage and so on. It can effectively treat the proximal humerus three-and four-part fractures, especially to elder patients.

Objective The aim of this study was to investigate the relationship between obesity [measured by body mass index(BMI), waist circumference(WC), waist-to-hip ratio(WHR)]and arterial stiffness on community populations in Beijing area. Methods In a cross-sectional study of 2664 subjects(1379 men and 1285 women)aged(53.19 ± 15.73 years, mean±standard deviation), BMI, WC, WHR and other cardiovascular risk factors, were measured and carotidfemoral pulse wave velocity(cfPWV)was measured to assess the arterial stiffness. All the data were analyzed with linear correlation analysis, univariate analysis and stepwise regression method to explore the relationship between obese indexes and arterial stiffness. Results We noticed that a showed the existence of positive correlations between BMI(r=0.0829,P＜0.01)and cfPWV, WC(r=0.2659, P＜0.01)and cfPWV, WHR(r=0.2749, P＜0.01)and cfPWV, in univariate analysis,cfPWV was associated with WC≥85 cm(male)or ≥80 cm(famale)(P＜0.01), WHR≥0.90(male)or≥ 0.85(famale)(P＜ 0.01). Stepwise regression analysis revealed that WC was an independent risk factor of cfPWV, other than age, gender, systolic blood pressure, HDL-C, OGTT2h etc. Conclusion Our findings indicated that obesity was an independent risk factor of cfPWV, which was an early marker of cardiovascular and renal diseases, among community population in Beijing area. There were different relationships between obesity measurement parameters(BMI, WC, WHR)and cfPWV.

OBJECTIVETo investigate the effects of angelicanaphtha on proliferation, cell cycle, apoptosis, and collagen synthesis of human umbilical vein endothelial cells (HUVEC).

METHODSHUVEC was cultured and passaged in Dulbecco's modified Eagle's medium (DMEM) and treated with angelicanaphtha 1 mg/ L, 4 mg/L, and 16 mg/L at 1, 3, 5, and 7 day respectively. The proliferation was measured with MTT method. The cell cycle and apoptosis were analyzed with flow cytometry and collagen synthesis was determined with radioimmunoassay.

RESULTSThe proliferation of the HUVEC was accelerated by angelicanaphtha < or =4 mg/L and inhibited by angelicanaphtha at 16 mg/L (P < 0.05). Lower concentration (< or = 4 mg/L) of Angelicanaphtha decreased cells in G0/G1 phase and increased significantly cells in S phase and inhibited the apoptosis (P < 0.05). However, angelicanaphtha at 16 mg/L increased cells in G0/G1 phase and decreased cells in S phase and induced the apoptosis (P < 0.05). The collagen synthesis of HUVEC was inhibited by angelicanaphtha in concentration-dependent manner (P < 0.05 or 0.01).

CONCLUSIONThe proliferation effects of angelicanaphtha on HUVEC had dualistic regulation of increase by lower-concentration and inhibition by higher-concentration. Collagen synthesis of HUVEC was inhibited by angelicanaphtha in concentration-dependent manner.
