[Objective]To explore the technique and results of reverse less invasive stabilization system(LISS) plating for subtrochanteric femur fractures.[Method]From October 2007 to May 2009,31 cases of fresh subtrochanteric femur fractures were treated with reverse LISS. There were 23 males and 8 females,with an average age of 48.6 years (range 27 to 83 years). Twelve injuries were the result of a traffic accident,six,a fall from a greater height,four,a crush injury and nine,a fall from a standing height. According to Seinsheimer classification,four fractures were type ⅡC,twelve ⅢA,six ⅢB,six Ⅳ and three Ⅴ. After anesthesia was effectively administered,subtrochanteric fracture was reduced indirectly with patient on a fracture table. Then,the reverse LISS plate was inserted through a lateral incision of the greater trochanter between the lateral vastus muscle and the periosteum. Guided by the aiming arm,4 to 5 screws were inserted through stab incisions into the proximal and distal fragments,respectively. [Result]Operative time averaged 50 minutes (range,35-80 minutes) and estimated blood loss averaged 90 ml(range,60-150 ml). Thirty-one patients were available for evaluation with an average follow-up of 15.6 months. All fractures healed at a mean of 18.2 weeks (range 13 to 32 weeks). There was no failed fixation,or deep infection. Average range of motion of the hip joint was recorded as follows:flexion 115?,external rotation 35?,internal rotation 15?,adduction 15?,and abduction 36?. According to the modified Harris hip score,scores ranged from 82 to 100 (average,92.6),and there were 24 excellent and 7 good results.[Conclusion]Reverse LISS plating yields good results in subtrochanteric femur fractures,with stable fixation and minimal invasive procedure.

[Objective]To explore the operative techniques of open reduction and internal fixation of displaced radial head fractures in adults. [Methods]Twenty-six cases of radial head fractures had been treated with open reduction and internal fixation. According to Mason classification, 16 fractures were type II, 6 were type III and 4 were type IV. Operative exposures of radial head were performed through the Kocher approach in 22 cases, and through a midline posterior skin incision in 4 cases in order to repair concomitant fracture of proximal ulna. After being reduced, fractures of radial head were fixed with mini-fragment plate and screw which were placed in "safe zone" not to impinge on the proximal radioulnar joint with forearm rotation.[Results]At a mean follow-up of 32 months, all fractures had united. There was no patient who suffered from wound infection or injury to posterior interosseous nerve. According to the Broberg and Morrey functional elbow index, the outcome were excellent in 17 patients, good in 9.[Conclusion]Open reduction and internal fixation of displaced radial head fractures may get satisfying outcomes, with successful performing of the requirements below: (1) sustaining lateral ulnar collateral ligament; (2) avoiding injury to posterior inerosseous nerve; (3) getting anatomic reduction; (4) stably fixing fractures without impinging on joint.

Objective To explore the effect of enteral nutrition applied to bowel preparation of diabetes patients before electronic colonoscopy. Methods A total of 172 diabetes patients were randomly allocated to the experimental group and the control group with 86 patients in each group. The experimental groups executed no dietary restriction within 3 days before the examination, and received Ensure 1h before colonoscopy. However,the control group was given low residue diet within 3 days before the examination, and received no Ensure before colonoscopy. The enteral cleanness and incidence of hypoglycemic reaction, abdominal pain and horror was compared between the two groups. Results 72 cases(83.72%) of the experimental group and 70 cases (81.40%) of the control group had better enteral cleanness, and there was no statistical difference in intestinal cleanness between the two groups. In the experimental group the incidence of hypoglycemic reaction, abdominal pain, horror was significantly lower than those in the control group. Conclusions Bowel preparation with unrestricted diet and ingested ensure before colonoscopy can not only ensure intestinal cleanness but also enhance endurance of colonoscopy.

Objective To study the changes of circulating triglyceride (TG) in the obese elderly, and to investigate the effect of hypertriglyceridemia on the development of insulin resistance. Methods A total of 82 subjects were divided into simple obesity group, obesity with IGT group, obesity with T2DM group and normal control group. The body height, body weight, blood pressure, fasting plasma glucose (FPG) and insulin(FPI), circulating TG and total cholesterol (TC) were measured. The homeostasis model assessment-insulin resistance (HOMA-IR) was calculated. Results The levels of serum TG were significantly higher in the simple obesity group ( 1.3 ± 0. 6) mmol/L, obesity with IGT group (1.9 ± 0.9)mmol/L and obesity with T2DM group (2.1±0.7) mmol/L than in the normal controls [(1.0±0.2)mmol/L, all P<0. 05], Furthermore, the levels of TG, FPG, FPI, HOMA-IR and systolic pressure were significantly higher(all P<0. 05) in obesity with IGT group and obesity with T2DM group than in simple obesity group. There were significantly positive correlations between TG and body mass index (BMI), FPG, HOMA-IR, TC, systolic pressure respectively (all P < 0.05). Multiple linear regression analysis indicated that FPG and HOMA-IR were the independent factors affecting TG (both P < 0. 05 ). Conclusions Hypertriglyceridemia may play an important role in the development of insulin resistance.
