ObjectiveTo review the management and prevention of stenosis after hepaticojejunostomy. MethodsWe retrospectively analyzed 133 patients who developed stenosis after hepaticojejunostomy carried out for iatrogenic bile duct injuries. ResultThrough our active reoperative protocol, we were able to achieve satisfactory results in 131 patients, although the results were still unsatisfactory in 2 patients. ConclusionsStenosis after hepaticojejunostomy is a severe complication which should actively be prevented. Once it happens, doctors should apply active, appropriate and effective measures to correct the stenosis.

Objective To pay close attention to and reverse the increasing trend about missed diagnosis and misdiagnosis of carcinoma of gallbladder and bile duct in laparoscopic cholecystectomy(LC). Methods By using retrospective analysis of 17 cases of missed diagnosis and misdiagnosis of carcinoma of gallbladder and bile duct in LC, their Clinical features and proposing protective measures were summarized. Results Seventeen patients including 14 with carcinoma of gallbladder and 3 with carcinoma of bile duct received various therapeutic measures according to their own conditions or aspirations. Conclusion Rapid intraoperative frozen section diagnosis is required for the cases with suspected carcinoma in LC and second operation is performed for those who are pathologically diagnosed with malignant tumor after the first one. No pathological diagnosis is strictly prohibited.

Objective To explore the emergency management and prevention of iatrogenic injury of in-ferior vena cava. Methods A retrospective study was undertaken to investigate the operative procedure and post-operative outcome of 7 patients suffering from iatrogenic injury of inferior vena cava in the course of three nephrectomy, one fight adrenal gland tumor resection, one fight surgical kidney, one right upper retro-peritoneal tumor and one pancreaticoduodenectomy. The gross hemorrhage was controlled by local pressure. Then, abdominal incision was done. Firm pressure on the inferior vena cava was performed to right side for temporary control of hemorrhage. The bleeding part could be found when the hematocele was cleaned. And continuous suture should be done with 3-0 silk or absorbable suture after the crevasse was clamped. Results In these 7 cases, 1 died of hemorrhagic shock and the other 6 had significant effect postoperatively. The asso-ciated injuries were healed well except 1 case of slight edema of lower extremity. Conclusion Iatrogenic inju-ry of inferior vena cava can be treated successfully with correct procedure. Furthermore, the injury could be avoided with exactitude intraoperative procedure.

Objective To analyze the risk factors for thrombosis by investigating the incidence of central venous catheter‐related thrombosis in elderly patients .Methods Four hundred and five elderly patients who underwent central venous catheterization were divided into femoral vein group(n=46) ,internal jugular vein group (n=40) and subclavian vein group (n=319) according to their catheter position ,or into thrombosis group (n=31) and non‐thrombosis group (n=374) according to the incidence of central venous catheter‐related thrombosis .T heir gender ,age ,basic diseases ,catheter position ,retention time of catheter ,and complications of central venous catheter‐related thrombosis were retrospectively analyzed .Results The incidence of central venous cathe‐ter‐related thrombosis was significantly lower in subclavian vein group than in internal jugular vein group and femoral vein group (5 .0% vs 15 .0% ,5 .0% vs 19 .6% ,P<0 .05 ,P<0 .01) .The percentage of past venous thrombosis history was significantly higher in thrombosis group than in non‐thrombosis group (19 .4% vs 6 .4% ,P<0 .05) .Conclusions Subclavian vein catheterization can significantly reduce the incidence of central venous catheter‐related thrombosis and past ve‐nous thrombosis history can predict the incidence of central venous catheter‐related thrombosis in elderly patients .

According to the Common Specification of Medical Electrical Equipment with GB 9706.1—2007 and the Environment Requirements and Testing Ways of Medical Electrical Equipment with GB/T 14710—1993,the solving methods in the electrical examination are put forward. Application of the practical method of operation,reasonable and effective protective measures to address the medical electrical equipment for general safety requirements and the environmental requirements test and the actual operation encountered some problems. The medical electrical equipment has been designed and tested in scientific and accurate electrical testing,electric shock protection,environmental testing,and the results of the operation specification.

AIM:To observe the effect of Rheum emodi Wall on expess level of TNF-?、IL-1? and IL-6 on acute ischemic stroke(ACI)at high altitude. METHODS: 65 patients aith ACI at high altitude(2 260 m)were randomly divided into treatment group(34) and control groups(31).both groups received danshen-safflower injection.Meanwhile treatment group took Rheum emodi decoction orally for 4 weeks,while control group doesn't.Serum levels of TNF-?、IL-1? and IL-6 were measured by radioimmumoassay. RESULTS: The treatment group showed much higher rates of improvement than control group(88.24%;70.97%)after weeks.Serum levels of TNF-?、IL-1? and IL-6 decreased significantly in patients with ACI at treatment group as compared with those of control group. CONCLUSION: Rheum emodi Wall can improve the nervous function of ACI by reducing TNF-?、IL-1? and IL-6 content in serun.

Objective To investigate the effect of antiserum against VEGF on angiogenesis and growth of bladder cancer in a mouse model in order to explore a novel strategy for the treatment of bladder cancer. Methods Antiserum against VEGF was prepared by using recombinant human VEGF and was identified for its specific affinity with VEGF by ELISA.The bladder carcinoma cell lines BST739 were implanted in T739 mice which were randomly divided into 2 groups:the control group receiving normal mice serum intraperitoneally,and the experimental group receiving antiserum against VEGF intraperitoneally.All the animals were sacrificed at last.Then all the bladder carcinomas were weighted and the microvessel density (MVD) in them was studied by immunohistochemical staining. Results The antiserum against VEGF was prepared and demonstrated with high specificity. The MVD in the antiserum group was lower than that in the control group. But the average weight of tumors was not significantly less in the antiserum group. Conclusions The study shows that to inhibit the activity of VEGF may reduce the angiogenesis in bladder cancer and supports the antiangiogenic therapy for bladder cancer.Inhibition of VEGF activity might become an important way of adjuvant therapy for bladder cancer.

Objective To explore the diagnostic and therapeutic methods for male breast cancer. Methods Clinical data of 11 cases of male breast cancer treated in our hospital from 1992 were analyzed (retrospectively). Results 2 patients were diagnosed at advanced stage and survived 6 and 8 months (respectively) after biopsy. The other 9 patients received radical mastectomy. 3 were lost to follow-up, 1 was found to have pulmonary metastasis after 5 years and combined treatment of traditional Chinese medicine and western medicine was given. Nodules were found under the axillary fossa in another patient at five years after surgery and the nodules were recurrent carcinoma as confirmed by biopsy. The patient has survived for 7 years with radiotherapy and chemotherapy. The other 4 cases have survived 0.5 to 7 years respectively, and are undergoing treatment. Conclusions Early diagnosis of male breast cancer should be emphasized. Aggressive surgery combined with other auxiliary treatments are effective.
