Chronic wound has very complicated pathogenesis and is difficult to treat; the situation has been improving owing to the progress in wound healing research and the clinical application of new techniques. This article focuses on the pathogenesis of chronic wound and introduces progress in various kinds of treatment, such as skin substitute, growth factors, negative pressure treatment, etc.

ObjectiveTo discuss treatment experiencing in femur periprothetic fracture after hip arthroplasty in pre-, intra- and post-surgery.Methods From March 2005 to May 2011, 27 patients (11 males, 16 females) aged ＞75 years with femur periprothetic fracture after hip replacement were studied. The mean time from primary hip replacement to femur perprosthetic fracture was 63 months(ranging from 7 to 83 months). According to vanconver classification, type A applying steel wire of character for 8 bind technique was 5 cases, type B applying prolonging stem technique locking compress plate (LCP)technique surrounding instrument technique was 19 cases and type C applying bone graft and plate fixation technique was 3 cases. All patients were followed up from 9 to 25 months (average, 16 months). The results of treatment were evaluated by Harris score and X rays. Results Bony heal was obtained in 22 patients and was not obtained in five cases among whom bony heal occurred in 3 cases and 2 patients could only keep prothetic and limb stable after receiving the bone graft once more. Walking was free in 14 cases,9 cases needed assistant walking instrument,and only 4 cases stayed in the bed freely. Harris score for last follow-up was 52 to 93 (mean 76).Conclusions Based on the patient general status, the fracture types and practical and stable principle, the effective methods can get good results in the treatment of femur periprosthetic fracture in aged patient.

0.05).) Conclusions Coxsackie virus is the most common pathogen in patients with viral meningitis in Chaoshan district, and the organization of disease prevention and scientific research and clinical medical should attach importance to it.

The health information social service in medical college and university libraries was analyzed in terms of the importance attached to it, opening to readers, items of service, requirement of materials, types of readers, and charge of frees, and certain measures were proposed for improving the level of health information social service, such as updating the service concept, innovating the service, and standardizing the management.

Objective To investigate the relationship between motor abnormality of sphincter of Oddi(SO) and hepatolithiasis.Methods The hepatolithiasis rabbit models were established in adult rabbits(n=64) which were randomly divded into 2 groups:control group(n=16)and experimental group(n=48),including 2 wk,4 wk and 8 wk group(n=16 per group).During the formation process of hepatolithiasis,bile character and ratio of stone formation were both observed,then the myoelectric waves of SO were recorded.Finally,The SO segment was sliced and observed by transmissional electron microscope.Results The rate of true stone formation in group 8 wk(68.75%,11/16)was higher than that in group 4wk(12.50%,2/16)and in group 2wk(0.00%,0/16).Compared with the control group,there was significant decrease of both SO myoelectric peak amplitude and SO myoelectric frequency in the experimental group.Electron microscopy showed that SO cells in control group and 2wk group had no change,but the 4wk and 8wk groups underwent changes including fibrolysis of myofilament,increase of collagen fibers,fusion and thickening of microfilament,decrease and array disorder of macula densa,swelling of chondrosome and endoplasmic reticulum,widening of perinuclear space and deviation and pyknosis of nucleus,and formation of inclusion body in cytoplasm;and the degeneration degree in 8wk group was obvious than that in group 4wk.Conclusions The functional abnormality of SO may contribute important effects on the formation of hepatolithiasis.Fibrous degeneration of SO maybe the pathogenesis of functional abnormality of SO.

Andrology and gynecology have a similar or the same theoretical basis in Traditional Chinese Medicine (TCM). Andrology has a history of less than 3 decades in China, while TCM gynecology has developed for over a thousand years. The development of andrology could be greatly promoted with the guidance of the theories and prescriptions of gynecology.

Septic arthritis of the sternoclavicular joint(SCJ) is a rare condition and accounts for 0.5％-1.0％ of septic arthritis.SCJ infections often require surgical intervention.Diabetes mellitus,rheumatoid arthritis,intravenous drug use,intraarticular injection and immunosuppressive disorders are predisposing factors.Staphylococcus aureus and Pseudomonas aeruginosa are the most common bacteriologies.Early diagnosis of SCJ infection requires a high index of suspicion and a confirmatory CT or MRI scan.The characteristic imaging features include intramedullary and soft tissue gas,sequestra,soft tissue swelling and destruction or widening of joint space.Management strategies have ranged from conservative antibiotic therapy to en-bloc resection of the sternoclavicular joint with or without ipsilateral pectoralis major muscle transposition.The shoulder function in most patients were well preserved.
