Objective:To investigate infection status of hepatitis B virus in ChongQing children. Method:We detected the HBV serology markers(HBVM) hy ELISA in 8060 children in Children's Hospital of Chnngqing Medical University. Results:HBsAg positive rate was 4.44%,anti—HBs positive rate 46.56%. 3795 cases were negative in HBVM(47.08%);259 cases were positive in HBsAg,HBeAg and anti-HBc(3.21%);80 cases were positive in HBsAg, anti-HBe, anti-HBc (0.99%),and Pre-S1 positive rate was 3.51%. Conclusion:Among the 8060 children who came to our hospital,the infection rate of HBV is 4.44%,lower than in the adults. Pre-S1 is related with HBeAg,and it can reflect the status of HBV multiplication and infectivity to some extent.

Objective To analyze the clinical characteristics of adult intussusception and improve its diagnostic and treatment levels.Methods Data of 80 cases of adult intussusception treated in the First Affiliated Hospital of China Mdeical Unuversity between January 2001 and December 2015 were reviewed retrospectively.Results 95％ patients had abdominal pain,34％ had bloody stool and 24％ had abdominal mass,8％ presented a triad of abdominal pain,bloody stool and abdominal mass.As confirmed by laparotomy 48％ were enteric intussusception,40％ were ileocolic intussusception,and 12％ colocolonic intussusception.The diagnosis rate of abdominal uhrasonography was 60％;CT established the diagnosis in 97％ cases.74％ underwent malignant or benign tumor resection,10％ underwent intestinal resection for inflammatory bowel disease.10％ were cured by simple reduction.4 cases received intussusception reduction and appendectomy.Conclusions Tumors were causes of adult intussusception in most case.CT is most accurate in diagnosis.Laparoscopy can be used for difficult diagnosis.

Objective To evaluate the prevention and treatment of prosthetic infections after tension free hernioplasty. Methods The clinical date of 12 prosthetic infections admitted from May 2005 to May 2008 were analyzed retrospectively. Patch was inserted under prefascial retromuscular site in 8 cases, between fascial edges in 2, Mesh plug and patch Lichentstein in one each. As for the material used there were flat knitted polypropylene in 7 cases, polytef in 1 case and composite prosthesis in 4 cases. Treatments were based on prothetic materials and levels infected. Infectious patchs were removed completely in 8 cases and partially removed in 2 cases, Open dress change with patchs left in situ in 2 cases. 3 cases in 10 cases of removed patchs were given immediate suturation with closed drainage. Results Infection was cured in all cases without mortality. There was no hemorrhage and injury of bladder during the procedures. No retention of urine, pain and other complications during postoperation. Change of dressing was made from 7 days to 6 months( median 2 weeks). Selected antibiotic was used from 3 to 7 days (average 4.5 days). All patients were followed up from 18 to 78 months (average 38.5 months) without hernia recurrence and infection. Conclusion It was most important to prevent infections after tension-free hernioplasty. Management should be individualized according to different type of patch used and the surgical procedure in hernia repair.

Objective To investigate the functional changes of endothelial cells (EC) in non-thrombosis vein segment (ECNT) in rats with experimental venous thrombosis (VT). MethodRats were divided into normal, control, and thrombosis group caused by legating a portion of iliac vein with 30 animals in each group. Endothelium was sampled from superhepatic IVC. Samples were studied by electroscopy, immunohistochemistry, and Western blotting for apoptosis. ResultsMorphological and functional changes of the ECs were observed in sampled superhepatic IVC. Compared with normal and control group the apoptosis rates(P

Objective To assess the efficacy and safety of interventional combine with surgical therapy of symptomatic portal vein thrombosis (PVT). Methods Seven patients with PVT were treated by surgical thrombectomy, regional medical thrombolysis, and angioplasty or stenting. Resection of part of the small intestine was performed in 2 cases due to enteric necrosis and in 1 case because of enteric stenosis. Results The procedure was successful in all the 7 patients. The preoperative symptoms (abdominal pain, distention, and ascites) were alleviated apparently. Follow-up observations for 3~24 months (mean, 16 months) showed no death. No alimentary tract hemorrhage occurred. Re-examinations with Doppler ultrasonography revealed patent blood flow in the portal vein. Conclusions Interventional combined with surgical therapy is safe and effective in the treatment of symptomatic portal venous thrombosis.

Objective To evaluate the effect of local resection for the tumor of Vater ampulla. Methods seventeen cases of Vater ampullary tumor were subjected to tumor local resection from November 1987 to December 1998, including 3 adenomas and 14 adenocarcinomas confirmed by pathology. Two methods of excision for the tumor were performed, including through duodenum to perform the tumor local resection in 16 cases, and through common bile duct in 1 case. Results Bile duct infection occurred in 3 cases. There was no death in this series. 12 of the 17 cases (70.6%) had been followed up for 4～61 months, median survival time was twelve months. In three benign cases ,one died with another disease 17 months postoperatively, two still alive well 38 and 7 months after operation respectively. In 14 malignancy, 9 cases (64.3%) had been followed up. Of the 9 cases, 6(66.7%) alived ≥ 12 months, 4 (44.4%) 24 months, two(22.2%) 60 months. Conclusions Local resection of the Vater ampulla tumor has advantages, such as small damage ,less bloodlass, quick recovery and less interference of the body, but it must be performed by rich experienced surgeons. It is suitable for patients with a small benign tumor, or in the high risk patients whose carcinoma showed no invasion or metastasis, and it also can be performed in patients such as those with atypical hyperplasia and suspious malignant tumor.

Objective To evaluate catheter-directed thromlysis (CDT) through three different approaches in combination with intervention for acute deep venous thrombosis (DVT) of the lower extremities. Methods In this study 137 acute DVT cases were enrolled. CDT was performed through small saphenous veins in 107 cases,through the great saphenous veins in 21 and through popliteal veins in 9.Iliac vein balloon dilation was performed in 66 cases,and stents were placed in 60 cases. Results The limb edema reduction rates between small saphenous vein group and great saphenous vein group and popliteal vein group were of no significant difference (82.3％ ±7.6％ vs 81.6％ ±6.0％ vs 83.9％ ±6.1％,P＞0.05).The difference of rates of thrombolysis ( 63.5 ％ ± 7.7％ vs 66.9％ ± 8.4％ vs 66.1％ ± 2.7％ )between the 3 groups was not statistically significant (P ＞ 0.05 ). The mean time required for the cannulation was shorter in great saphenous vein group than the other two groups [ (7.3 ± 0.3 ) min vs (20.8 ± 1.1 ) min and (15.7 ±0.6) min,P ＜ 0.05 ].There were 12 cases complicating incision bleeding during thrombolysis in small saphenous vein group,in this group there were 5 cases complicating phlebitis and 8 complicating saphenous nerve injury.The complication rates in great saphenous vein group was lower (P ＜ 0.05).Follow-up made in 112 cases for 3 -25 months.There were 97 cases without limb edema.While test by venography or color Doppler,89 cases showed venous patency and rethrombosis developed in 8 cases. Conclusions Catheter-directed thrombolysis with iliac venous intervention was an effective method for the treatment of acute deep venous thrombosis.CDT through great saphenous vein is easier with less complications.

Objective　To evaluate the results of radical resection for the treatment of Budd-Chiari syndrome (BCS) caused by short segmental lesions in inferior vena cava (IVC), and major hepatic veins (MHV).　Methods　In this series, resection of IVC occlusive segment and orthotopic artificial vascular graft transplantation were performed in 42 patients. Resection of major hepatic vein, hepatic venous plasty and orthotopic transplantation with artificial vascular graft were performed in 10 patients. Resection of major hepatic vein, anastomosis between hepatic vein and right artrium in 3 cases. Percutaneous transhepatic angioplasty in 10 cases.　Results　One patient died of complication. 58 cases were followed up for an average of 30 months. 3 cases in interventional group suffered recurrence and one in surgical group had recurrence.　Conclusions　The treatment of BCS by resecting inflicted segment of IVC or hepatic veins and orthotopic artificial vascular graft transplantation effect a radical cure in most cases.
