Objective To study the postoperative survival rate of elderly patients with hip fracture at different time and its related factors.Methods We conducted the follow-up studies of 255 elderly hip fracture patients from June 2008 to June 2011 in our hospital.The survival rates of patients at 6 months,1,2 and 3 years after operation and their related factors were studied.Results The survival rate was 96.5%,89.8%,78.0% and 69.4% at 6 months,1,2 and 3 years after operation respectively in 255 elderly hip fracture patients.Survival analysis showed that many kinds of preoperative comorbidities,low albumin level,old age and severe anemia were the risk factors for survival.Good activity of daily living before injury was a protective factor for survival.Gender,fracture type,the American Society of Anesthesiologists (ASA) classification,time from injury to surgery,anesthesia type,surgical approach,operative time,blood loss and hospital stay periods had no effect on survival after operation.Conclusions The survival rate in elderly patients with hip fracture after surgery is affected by many factors.Preoperative comorbidities,anemia and hypoalbuminemia should be actively treated,the activity of daily living should be improved by the directed therapy and rehabilitation,in order to improve the survival rate in elderly patients with hip fracture.

Objective To study the efficacy and safety of in vitro local drug delivery capsules fabricated with the biodegradable material Osteoset(R)plus vancomycin and recombinant human bone morphogenetic protein-2 (rhBMP-2). Methods In vitro local drug delivery capsules were fabricated with the biodegradable material Osteoset(R) plus vancomycin and rhBMP-2.High-Performance Liquid Chromatography (HPLC) and bacterial inhibition tests were performed to detect the concentration and activity of vancomycin in the capsules.Enzyme-linked immunosorbent assay(ELISA) and alkaline phosphatase(ALP) tests were conducted to detect the concentration and activity of rhBMP-2 in the capsules. Results The capsules could release vancomycin above 55.8 μg/mL for up to 144 hours,with an activity of above 70%.They could release active thBMP-2 for up to 30 days,had no inhibition effects on the proliferation of mesenchymal stem cells(MSCs) and had high biological safety. Conclusion Since the capsules of Osteoset(R) plus vancomyein and rhBMP-2 can release high concentrations of active vancomycin and active rhBMP-2 with no inhibition of the proliferation of MSCs,they have good prospects for clinical use.

Objective To investigate the technique of design and cutting method of the thoraco- um-bilicus flap.Methods (1) Made the skin flap include not only the vascularity skin of this side,but also the opposite side,to repair overlength and overbreadth wound surface.(2) Improvement of skin flap cutting steps:first to find the blood vessel under the lower abdominal wall,then to cut the skin flap,if not find to have another donor area.(3)Technology of making thin skin flap:when cutting open the skin,made the surgical blade inclined to the flap,beveling to 2/3 of the skin flap length and in hypogastrium cutting to all over the flap with the fat keep stay in the abdomen so to make the skin flap thiner.Results There was 1 case necrosis because of infection in all 54 cases be repaired.The achievement ratio was 98.1%.Follow up with 1-5 years,skin flaps appearance was good,joint extend- bend was gratification.Soft tissue infection was cured.Conclusion Modified technology of thoraco-umbilicus flap is reasonable design and easily to cut,and the achievement ratio is higher.

@#Objective To study the incidence, character and related risk factors of post trauma stress disorders (PTSD) after road traffic accidents. Methods Inpatients after road traffic accidents from January 2001 to January 2005 were surveyed with self-made questionnaire. The incidence, clinical symptoms and related factors of PTSD were analyzed. Results 156 cases (7.53%) were diagnosed as PTSD among all subjects and their major clinical manifestation including difficulty of falling or staying asleep, compulsion of re-experience traumatic process and excessive startled reactions. The related factors of PTSD including the personality, the degree of education, family harmony and compensation. Conclusion PTSD is common in patients injured in road traffic accidents. Early psychological intervention for susceptible may be needed.
