Objective to study the factors of delaying survival of the ankle and foot which were linked with leg only by skin, fascia and tibia after all the infected and inactivated muscles and intermuscular vessels had been removed, and to study the effect of artery blood supply reconstruction to avoid the necrosis and ischemia contracture of the foot. Methods The leg was linked with ankle and foot by the tibia which was covered only by skin and fascia after all the muscles, interosseous membrance, intermuscular vessels and fibula had been removed. And then the artery blood supply for the injured limb was reconstructed by stages. Results The sense of haphalgesia, with normal temperature and color, recovered in the injured limb 7 months after operation, no contracture and deformity happened in the food muscles and joint, and the patient may smooth stand and walk with a stick freely. Conclusion The necrosis and ischemia contracture of foot was delayed by reticular collateral circulation among skin, deep and superficial fascia and tibia of the injured limb, although the blood supply was very little after all the muscles and intermuscular vessels had been removed because of infection and necrosis. Finally the injured limb was reserved successfully by artery blood supply reconstruction. The clinical effect was satisfactory.

Objective　To investigate the operation treatment of gallbladder carcinoma(GBC). Methods The clinical data of 132 patients with GBC from 1980 to 1999 were analysed. Results　The mean age was 55 years and the occurrence sex ratio in female/male was 1.5∶1. Gallstone was found in 80% of the patients, and 87.1% of the GBC were adenocarcinoma. Before December 1990(forward group), simple cholecystectomy were performed on 11 cases, radical cholecystectomy on 9 cases, extended radical cholecystectomy on 5 cases, palliative extra- or intra- drainge on 15 cases, surgical biopsy on 30% cases. Hospital death occurred in 4 cases, the postoperative complications occurred in 20 cases including biliary fistula in 4 cases, pancreatic fistula in 2 cases. Since January 1991(latter group), radical simple cholecystectomy were performed on 2 cases, radical cholecystectomy on 16 cases, extended radical cholecystectomy on 24 cases; palliative extra- or intra- drainge in 9 cases, surgical biopsy on 8 cases. Hospital death occurred in 1 cases; postoperative complications in 12 cases, including biliary fistula in 1 cases, pancreatic fistula in 1 cases. Radical resection rate was 35.7% in forword group, 72.6% in latter group. Conclusions　Surgical tech-nique progress and application with Peng's Multifunctional Operative Dissector can improve the resection rate of GBC. Extended redical resection is an effective and active method to treat middle or late stage GBC.

Objective To determine relationships between daily activities measured as modified version of Pulmonary Functional status and Dyspnea Questionaire (PFSDQ-M) and functional capacity and symptoms experienced in patients with chronic obstructive pulmonary disease (COPD). Methods Convenience sample of 94 COPD patients with stable condition were assessed by interview with PFSDQ-M Chinese version and modified Medical Research council dyspnea scale (MMRC) respectively. Pulmonary function test (PFT) and 6-minute walking test (6MWT) were undergone on the same day or within one week as interview. PFSDQ-M has three subscales,i.e.,change experienced by patient with activities (CA),dyspnea with activities (DA) and fatigue with activities (FA). Results Scores of CA,DA and FA correlated to 6-minute walking distancer= (-0.37)- (-0.42),FEV_1 r=(-0.27)-(-0.32),FEV_1/FVC r= (-0.27)- (-0.32),dyspnea rated by MMRC (r=0.55-0.60) and BODE index (r=0.35-0.40),respectively (all P<0.01). dyspnea explained 26% of the variance in changes of activities. Conclusions Physical activities moderately changed in patients with stable COPD;Dyspnea is the best predictor of limitation of daily activities.

OBJECTIVETo investigate the prevalence and subtype distribution of human papillomavirus (HPV) infection and its correlation with age among women in Beijing urban area, and provide some epidemiological evidence for the clinical application of HPV vaccines.

METHODSWe collected cervical specimens from 1999 women in the Outpatient Department of our hospital, performed genetyping of HPV-DNA, and analyzed the incidence of HPV infection in different age groups.

RESULTSHPV infection was detected in 502 (25.2%) of the 1999 women patients, with 391 (19.6%) cases of high-risk HPV, which included 326 (83.4%, 326/391) cases of single infection. HPV-16 was the most common type (21.2%, 69/326), followed by HPV-52 (19.3%, 63/326) and HPV-58 (16.0%, 52/326). The prevalence of HPV infection was the highest among the women aged 41 -50 years and the lowest among those over 60 years.

CONCLUSIONThe subtype- and age-specific distribution of HPV infection among women in Beijing urban area shows an obvious heterogeneity, which deserves due consideration in the clinical application of HPV vaccines.
