Objective To evaluate the timing,feasibility and necessity of early laparoscopic cholecystectomy (LC) in management of patients with mild to moderate acute pancreatitis with gallbladder stones.Methods The clinical data of 75 patients with mild to moderate acute pancreatitis and gallbladder stones treated from September 2010 to August 2014 in our hospital were analyzed retrospectively.32 patients underwent LC within 48 hours of the pancreatic attack.The results were compared with those from 43 patients with delayed LC.Results All the patients were operated by experienced surgeons.There were no significant differences between the two groups in operation time,postoperative complications,intraoperative blood loss,conversion rates,white blood cell count,percentage of neutrophils and blood amylase before and after the operation (P ＞0.05).Patients who received delayed LC had longer hospital stay [(10.6 ± 1.3) vs (17.1 ± 1.8),P ＜ 0.05].The readmission rate in patients with delayed LC was 30.2％ (13/43),and most admissions occurred within 2 ～4 weeks of hospital discharge.In patients with early LC,one patient developed necrotic pancreatitis and died of septic shock.All the remaining patients were cured.Conclusions It is safe,feasible and necessary to perform LC within 48 h in patients with mild to moderate acute pancreatitis and gallbladder stones.Such patients have a high readmission rate and the best timing of delayed LC is within 2 ～ 4 weeks after discharge from hospital.

Along with the development of interventional appliances and proficiency of operational skills,the interventional diagnosis and treatment via hepatic portal vein system have achieved great progress and improvement.However,in order to further exploit the advantages of interventional diagnosis and treatment, the review of the anatomical structures,normal aberrance of portal venous system were needed.Getting familiar with pathologic condition to discover the new interventional appliances and embolic agents,and then in term of conduct the research on a very tough substancial base in a down-to-earth manner were important.

Many microbial pathogens,including those responsible for major enteric infections,exploit oligosaccharides that are displayed on the surface of host cells as receptors for toxins and adhesins. Blocking crucial ligand receptor interactions is therefore a promising therapeutic strategy. One approach is to express molecular mimics of host receptors on the surface of harmless recombinant bacteria that can survive in the gut. These recombinant probiotics bind bacterial toxins in the gut lumen with very high avidity,thereby preventing disease.

Fermentation property and kinetic analysis of the inhibition of in vitro growth of pathogenic Escherichia coli K88, O138 by Lactobacillus intestinalis isolated from porcine intestine mucus were investi-gated. The results of fermentation showed that L1 result in a pH of 3.90 within 12 h and a large amount of lactic acid production, with the concentration of 104.08 mmol/L. Kinetic analysis of the antibacterial activity of L1 metabolic product toward K88, O138 showed that CFUS display strong antibacterial activity toward K88, O138; the antibacterial activity of L1 CFUS was higher than the lactic acid control samples and was mainly due to the production of lactic acid; K88, O138 had the tolerance property toward pH 4.5.

Objective To investigate the histogenesis and clinicopathologic features of carcinosarcoma of the urinary bladder. Methods Two cases of carcinosarcoma (one man and one woman)were included.They were admitted to hospital with discontinuous,painless,macroscopic hematuria.Clinicopathalogic features of all findings of the 2 cases were reviewed. Results Cystoscopy of both cases showed that the tumors displayed polypous or cauliflower-like shape,and grew invassively.CT examination of the bladder wall confirmed the presence of parenchymatous tumor.Both of the 2 cases underwent partial cystectomy.Intraoperative examination showed the tumors were similar to carcinoma of bladder.Histopathology showed biphasic neoplasms with distinct high grade epithelial and mesenchymal components.Morphologic characteristic of the tumor was abnormally proliferative and the mitotic figures could be seen.One of the patients died within 11 months and the other,16 months following the operation. Conclusions Carcinosarcoma of the urinary bladder is a kind of rare malignant tumor that is most often in an advanced stage at presentation and has an unfavorable prognosis. It should be identified promptly and treated appropriately.Those who have discontinuous,painless,macroscopic hematuria should be warned of the risk of the disease.

Objective To understand the situation of oxidative stress among diabetic nephropathy (DN) patients and observe the antioxidative effect of losartan at increasing dose in DN patients. Methods Thirty type 2 DN patients who neither smoked and nor took antioxidants were selected. The study began with an initial 4-6 weeks screening-treatment. Eligible patients then received losartan 50 mg/d daily for 8 weeks followed by losartan 100 mg/day daily for an additional 8 weeks. Blood glucose and blood pressure were closely monitored over the whole study period. All patients were followed up every other weeks, their 24-hour urine samples,fresh urine and venous blood sample were collected to measure urinary protein and creatinine excretion, urinary 8-OHdG, SOD, TAOC and MDA excretion , serum SOD, TAOC , MDA and other blood biochemistry parameters. Urinary 8-OHdG was determined by capillary electrophoresis and liquid phase chromatography. Results The total 24 hours urinary 8-OHdG excretion and the serum MDA concentration were higher than the normal values. The serum and urine SOD concentrations were lower than the normal values. There was an improvement in urinary 8-OHdG,serum and urine SOD, serum and urine MDA levels with losartan therapy. Compared with losartan 50 mg/d, the antioxidative effect of losartan 100 mg/d was more noticeable. Obvious decrease in 24-hour proteinuria on exposure to losartan was found, without severe adverse effect. Conclusions Oxidative stress damage is active in DN patients. Losartan has antioxidative effect on DN patients. Compared with losartan 50 mg/d, the antioxidative effect of losartan 100 mg/d is more marked, without increasing side effect. Losartan's antioxidative effect may be involved in its beneficial mechanisms on DN.

Objective Assess the value of pleura sliding sign with chest ultrasonography in the prediction of pleura adhesion prior to video-assisted thoracoscopic surgery(VATS).Method 63 patients were evaluated for pleura sliding signs with chest ultrasonography at 9 points along the chest wall prior to thoracotomies and were compared with the findings of the same points during the operation.Methods Pleura sliding signs on 567 points were examined in 63 cases,and 106 points pleura adhesion were found by chest ultrasonography and 72 points were proved by operations.461 points were no pleura adhesion under chest unltrasonography and 495 points had no pleura adhesion confirmed by operations.Results The sensitivity,specificity,negative predictive value,positive predictive value and overall accuracy were 80.56%,90.03%,96.96%,54.72% and 9.07%,respectively.The Receiver Operating Characteristic(ROC)curve showed that there should be no pleura adhesion if there were more than 8 points positive pleura sliding signs.Conclusion Examination of pleura sliding sign by chest ultrasonography is helpful to predict the presence and location of pleura adhesion prior to VATS.

Aleutian mink disease parvovirus (AMDV) causes a persistent infection associated with immune complex disease, hypergammaglobulinemia, and high levels of antiviral antibodies. Despite the presence of an antibody, the virus is not cleared in vivo. Pre-existing antibodies may enhance viral infections, by Fc-receptor-mediated antibody-dependent enhancement (ADE), but the mechanism that underlies ADE has not been fully defined. Three models have been proposed, including: (1) interactions between antibody and FcR, complement C3 fragment and CR, or between C1q and C1qR, which promotes viral attachment to cells; (2) suppression of IFN-gamma-mediated host-cell antiviral gene expression by the upregulation of negative regulators of pathogen pattern recognition; and (3) the promotion of early IL-10 secretion. In addition, the role of cytokine IL-6 in ADE mediated disease development is discussed, to facilitate a better understanding of the pathogenesis of AMDV infection, as well as give insights into rational vaccine design approaches.
