Objective To investigate the clinical efficacy and safety of tolterodine combined with flupentixol melitracen in the treatment of women with overactive bladder (OAB).Methods 84 female patients with OAB were chosen and randomly divided into the observation group and the control group.42 cases in observation group were treated with tolterodine combined with flupentixol melitracen.42 cases in control group were only treated with tolterodine.The clinical efficacy was recorded and compared after treatment for 4 weeks.Results The total effective rate of the observation group was higher than the control group (95.24％ vs 76.19％,x2 =6.291,P ＜ 0.05).The 24h frequency of urination,the average 24h number of incontinence episodes,initial urinate capacity and maximum bladder pressure capacity had statistically significant differences between the two groups (all P ＜ 0.05).Conclusion Tolterodine combined with flupentixol melitracen in the treatment of women with OAB has advantages of short course of treatment,excellent efficacy,and few side effects.

Objective To investigate the protective effect of rosiglitazone on acute necrotizing pancreatitis (ANP) associated lung injury in rats.Methods Seventy-five male Wistar rats were randomly divided into sham operation group (SO group),acute necrotizing pancreatitis group (ANP group) and rosiglitazone pretreatment group (ROSI group).ANP model was induced by retrograde infusion of 5％ sodium taurocholate into the biliopancreatic duct.Thirty minutes after ANP induction,ANP groups were injected with 10％ DMSO (0.2 ml/100 g) through femoral vein,and ROSI group were injected with ROSI dissolved with 10％ DMSO (6 mg/kg) through femoral vein,while SO group was injected with normal saline,and 30 minutes later was injected with same amount of 10％ DMSO.Rats were sacrificed at 3 h,6 h and 12 h after the operation.Serum amylase and lung wet/dry weight ratio (W/D) were measured,lung tissues were harvested for pathologic examinations.STAT1 protein and phosphorylation-STAT1 protein (p-STAT1) expression were detected by Western blot.Results The serum levels of amylase,lung W/D,pathologic score of lung tissues in ANP group were increased with time,and reached the peak at 12 h,which were (5017 ± 203)U/L,3.12 ±1.30,(3.33 ±0.18) score,and these were significantly higher than those in SO group (P ＜ 0.05 or 0.01),the expression of STAT1 protein was not statistically significant,but the expression of p-STAT1 reached the peak at 3 h (5.23 ± 0.03),then it gradually decreased,but it was still significantly higher than that in SO group (0.16 ± 0.04,p ＜ 0.01).The serum levels of amylase,lung W/D,pathologic score of lung tissues in ROSI group at 12 h were (1912 ± 164) U/L,1.83 ± 1.26,(2.78 ± 0.16),which were significantly lower than those in ANP group (P ＜ 0.05).The expression of STAT1 protein was not statistically significant,and the expressions of p-STAT1 at 3 h,6 h,12 h was 0.41 ±0.04,0.22±0.05,0.15 ±0.03,which were significantly lower than those in ANP group (P ＜ 0.05).Conclusions Rosiglitazone has the protective effect on ANP associated lung injury by inhibition of phosphorylation-STAT1 protein expression in the early phase.

Objective To analyze the clinical features of hepatic veno-occlusive disease (HVOD) and to explore the diagnosis criteria and treatment.Methods A total of 50 cases of HVOD administrated at The First Affiliated Hospital of College of Medicine,Zhejiang University from August 2008 to August 2011 were analyzed for etiology,clinical manifestation,laboratory examination,image,pathological features and treatment.Results Among the 50 HVOD cases,38 cases (76％)had a history of taking Gynura segetum.The main clinical manifestations were ascites,hepatomegaly,right upper quadrant pain,jaundice,and weight gain.Laboratory examinations indicated liver function injury and increased serum CA125 level.Color Doppler ultrasound showed hepatomegaly,decrease in diameter of hepatic vein and slow blood flow.The computed tomography scan suggested hepatomegaly,enhanced scan showed liver inhomogeneous enhancement at portal and delayed phase,map-like changes and markedly decrease in diameter of hepatic vein.Pathological examination suggested hepatic sinusoid congestion,central vein stenosis and vessel wall thickening.The main therapy was anticoagulant treatment.One case cured,33 cases improved,13 cases uncured and three cases died.Conclusions HVOD because of taking Gynura segetum is common in Zhejiang Province,which can be diagnosed according to medical history,clinical manifestations, and typical image characteristic.However,diagnosis of the atypical cases still needs liver biopsy.Anticoagulation therapy can achieve better efficacy.

Objective To compare and analyze gene expression patterns in rat model of nonalcoholic fatty liver disease (NAFLD).Methods Twelve male Sprague-Dawley rats were randomly given either general diet (control group) or a high-fat diet (model group) for 4 weeks.The histopathologic changes of the liver were observed and gene expression patterns were analyzed and compared by cDNA mieroarray.Results Hepatocellular steatosis and inflammatory infiltration were observed in model group after high-fat diet for 4 weeks.Fifty-one differential genes were found in model group,20 of which were up-regulated (sterol regulatory element binding factor 1,stearoyl-coenzyme A desaturase 1 and Bcl 2 modifying factor)and 31 were down-regulated (peroxisomal enoyl coenzyme A hydratase 1,heat shock 70 protein 1A and ATPase inhibitory factor 1). The up-regulating genes were involved in lipogenesis and cell apoptosis,while down-regulated genes were involved in fatty acid oxidation, protein modification and energy metabolism.Conclusions The differential expression of genes may involve in the pathogenesis of NAFLD.

Objective To explore the clinical characteristics and diagnosis of autoimmune pancreatitis(AIP) with the aim to raise awareness of AIP.Methods Clinical data of 32 patients with AIP were retrospectively analyzed,including clinical manifestations,imaging features,laboratory examination,histopathology and treatment from November 2009 to April 2013 in the First Affiliated Hospital of Medical School,Zhejiang University.Results All 32 AIP patients including 25 males and 7 females had a median age of (62.5 ± 12.6) years (27-84 years).The initial symptoms included obstructive jaundice in 50.0％patients (16/32),abdominal pain in 43.8％ (14/32),fatigue and weight loss in 12.5％ (4/32),and bloody stool in 6.3％ (2/32).Laboratory findings revealed abnormal liver function in 6.3％ (2/32)patients,increased immunoglobulins in 71.9％ (23/32)patients and elevated IgG4 in 8/10 patients.Computerized tomography(CT) scan and ultrasonography were performed in all patients.Diffusely enlarged pancreas were found in 62.5％ (20/32) patients and focally enlarged in 37.5％ (12/32),additionally main pancreatic duct stenosis in 62.5％ (20/32) patients.Nineteen patients obtained histopathological examination,indicating pancreatic interstitial fibrosis,and infiltration of lymphocytes and plasma cells.Conclusions Autoimmune pancreatitis is an autoimmune disease which may be misdiagnosed as pancreatic cancer.The clinical features,laboratory findings,imaging characteristics,and typical histopathologic presentation,as well as good response to glucocorticoids provide supportive evidence for the diagnosis of AIP.

Objective To explore the curative effect and security of transurethral holmium laser resection for adult ureterocele.Methods 22 cases with adult ureterocele were retrospectively studied.Eight adult ureterocele cases were male and 14 cases were female.The mean age was 36.5 years (ranged from 20 to 67years).All of the patients were unilateral onset,15 cases on the left side and 7 cases on the right side.The mean course of the disease was 31 months (ranged from 15d to 12 years).The clinical presentations were varied.All 22 cases were treated by tran-surethral holmium laser resection.About one -third of cyst wall were left in order to avoid vesicoureteral reflux and hydronephrosis.Results All 22 cases succeeded uneventfully.The pathologic study confirmed that 22 cases were ure-terocele.The mean hospital stay was 8days (ranged from 6 to 12days).Mean follow -up time was 17 months (12 -26 months),while 2 cases were lost.All 20 cases urine alalysis was normal.Five patients showed no hydronephrosis, while 10 cases showed less hydronephrosis.Cystoscopy showed all 20 cases ureteral healing was smooth,and none showed recurrence of ureterocele.Voiding cystourethrography showed none of vesicoureteral reflux.Conclusion Transurethral holmium laser resection would be a good choice for adult ureterocele,because the treatment has the advantages of simple operation,low requirement of equipment,safety and reliability.Especially for the primary level hospital,transurethral holmium laser resection is worth further clinical promotion.
