Objective To investigate the relationship between non muscle-invasive bladder can-cer and polymorphisms of DNA repair genes among Han nationality in Shanghai. Methods From January 2006 to June 2008, 94 patients with non muscle-invasive bladder cancer and 304 controls were enrolled. Known single nucleotide polymorphism(SNP) in the XPC, XPG, XRCC1 genes were detec-ted by TaqMan real-time PCR. After adjusted for age, sex, and smoking, interaction effects of the genotypes and non muscle-invasive bladder cancer risk, genotypes and clinical and pathological features of bladder cancer were analyzed using unconditional Logistic regression. Results After adjusted for age, sex, and smoking, the XPC 939 Lys/Gln, XPC 939Gin/Gin genotype and XPG 1104 Asp/His, XPG 1104 His/His genotype were more frequent in patients with non muscle-invasive bladder cancer, adjusted OR=1.89, 95%CI 1.14-3. 23 and OR=1.07,95%CI 0.86-1.87, respectively. The XRCC1 Arg399Gln polymorphisms were not significantly associated with non muscle-invasive bladder cancer, adjusted OR= 1.15, 95% CI 0.55-2.40. There were no significant associations between tumor clinical and pathological features in patients who possessed either the XPC or XPG polymor-phisms (P>0.05). Conclusion XPC Lys939Gln and XPG Asp1104His may modulate non muscle-invasive bladder cancer risk among Han nationality in Shanghai.

Objective To explore the rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Design Restrospective case series.Participants 92 cases with idiopathic intracranial hypertension.Meth- otis All patients diagnosed with papilledema from January 1,2000 through May 1,2007 at our ophthalmology center.Consecutive pa- tients with a diagnosis of papilledema were identified.Patients with space-occupying lesions,hydrocepbalus,or meningitis were excluded. The remaining patients were evaluated with lumbar puncture,magnetic resonance imaging(MRI)and magnetic resonance venography (MRV).Main Outcome Measures The rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Results Excluding patients with mass lesions,meningitis,or hydrocephalus,the occurrence of CVST was 7 (7.6%)of 92 patients with presumed IIH.One additional patients had a diagnosis of suspected CVST.Cerebral venous sinus thrombosis was diagnosed in 1 of the 7 patients with MRI alone,whereas it was evident in all 7 patients with MRV.Conclusions Cerebral venous si- nus thrombosis accounts for 7.6% of patients with presumed IIH in our ophthalmology services.Magnetic resonance venography in com- bination with MRI is recommended to identify this subgroup of patients.(Ophthalmol CHN,2007,16:410-413)

Objective To investigate the suppression effects of Tripotolide (TL) on the pancreatic cancer xenograft models and angiogenesis. Methods The growth suppression effect of TL on SW1990 was determined using cell count kit (CCK-8), apoptotic cells induced by TL were examined by morphology and terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay. The inhibitory effects of TL on the growth of tumor xenografts and tumor microvascular density (MVD) were investigated. ResultsTL inhibited the growth and proliferation of SW1990 cells in a concentration-dependent and time-dependent manner. The inhibition ratios of cells treated at 160 mg/ml TL for 24 h was 50. 6%, the apoptotic rate increased from 9.6% in the control group to 45.1% (P <0.01 ). The inhibition rate of cancer xenograft growth was 89.9% when TL was intratumorally injected at the dose of 0.5 mg/kg. The expression of VEGF in tumor tissue decreased while MVD also decreased from 36.25±8.64 to 9.87±3.34 (P <0.01 ). ConclusionsTL induced prominent growth inhibition and apoptosis in human pancreatic cancer cell lines. TL.can attenuate the growth of pancreatic caner xenografts through its effect on antiangiogenesis.

Objective To investigate the dynamic expressions of CXCL11 and its role in the pathogenesis of acute necrotizing pancreatitis (ANP).Methods Forty-eight SD rats were randomly divided into control group and ANP group,with 24 rats in each group.ANP model was induced by retrograde injection of 4％ sodium taurocholate (1 ml/kg body weight) into the biliary and pancreatic duct.The rats were sacrificed at 1,3,6,12 hours.Serum level of amylase was determined,pathological changes in pancreatic tissue were routinely observed and scored.The expression of CXCL11 mRNA and proteon in pancreas was measured by fluorescence quantitative polymerase chain reaction and immunohistochemical method.The serum levels of CXCL11 were measured by enzyme-linked immunoadsorbent assay.Results The serum levels of amylase in ANP rats were significantly higher than those in control group [(6153 ± 355)U/L vs (185 ± 32)U/L at 6 h,P ＜0.05],pathological changes in pancreatre tisues were more significant in ANP rats,and the pathological score was significantly higher than that in control group [(9.00 ± 0.63) vs (0.33 ± 0.12) points at 6 h,P ＜ 0.05] ; the expressions of CXCL11 mRNA and protein in pancreatic tissue were significantly increased than those in control group (3.13 ± 0.43 vs 0.99 ± 0.24,2.76 ± 0.27 vs 0.33 ± 0.12 at 6 h,P ＜ 0.05).The serum level of CXCL11 was significantly higher than that in control group [(112.1 ± 14.2)ng/L vs (56.8 ±4.3) ng/L at 6 h,P ＜0.05)].Conclusions CXCL11 is an early inflammatory mediator in acute pancreatitis,and involved in the pathogenesis of ANP in rats.

OBJECTIVETo observe the clinical effect of self-formulated Tongdatang serial recipe (TDT) in treating antipsychotic drug-induced galactorrhea-amenorrhea syndrome (GAS).

METHODSOne hundred female schizophrenic patients with antipsychotic drug-induced GAS were selected and equally assigned to the treatment group and the control group at random. Both received antipsychotic drug-therapy, but combined with TDT and placebo respectively. The efficacy was evaluated by determining prolactin level before, 4 and 8 weeks after treatment.

RESULTSThe treatment course was completed in 96% of patients. Therapeutic efficacy on the 49 patients of the treatment group was cured in 31 (63.3%), markedly effective in 11 (22.4%), effective in 4 (8.2%) and ineffective in 3 (6.1%), with total effective rate of 93.9%, while in 47 patients of the control group, the corresponding cases (%) was 0, 3 (6.4%) , 7 (14.9%) and 37 (78.7%), respectively, with the total effective rate of 21.3%. Prolactin levels in the two groups were insignificantly different before treatment, it reduced in the treatment group after treatment (P < 0.01), and the decrement in the treatment group was more significant than that in the control group (P < 0.05).

CONCLUSIONSatisfactory effect could achieved by using TDT for treatment of antipsychotic drug-induced GAS.

Objective To explore the regulation and effect factors of arsenic expose and arsenic methylation level, then to provide a reference for study the function of arsenic metabolism in a arsenic poisoning process. Methods A meta-analysis was performed by two researchers. Twenty-five papers satisfying our priori eligibility criteria were included by searching Cochrane library, Pubmed, Springer, Embase and China National Knowledge Infrastructure. Based on the results of heterogeneity, a random or fixed effects model was chosen for the meta-analysis. Results The results showed that the following arsenic metabolites increased (all P<0.01) following arsenic exposure: inorganic arsenic [iAs; standardized mean difference (SMD): 1.07; 95% confidence interval (CI):0.61 - 1.53)], monomethyl arsenic (MMA; SMD: 1.10; 95% CI: 0.81 - 1.40), dimethyl arsenic (DMA; SMD: 2.50;95%CI:1.50-3.69), and total arsenic (TAs, SMD:3.10;95%CI:2.13-4.07). Additionally, the percentages of iAs (iAs%; SMD: 1.00; 95% CI: 0.60 - 1.40) and MMA (MMA%; SMD: 0.49; 95% CI: 0.21 - 0.77) also increased, while the percentage of DMA (DMA%; SMD: - 0.55; 95% CI: - 0.80 - - 0.31) decreased (P<0.01). The primary methylation index (PMI; SMD: - 0.57; 95% CI: - 0.94 - - 0.20), and secondary methylation index (SMI;SMD: - 0.27; 95% CI: - 0.46 - - 0.09) decreased (all P< 0.01). Compared to female, male had higher MMA%(SMD:0.44;95%CI:0.35-0.52), lower DMA%(SMD:-0.33;95%CI:-0.38--0.28) and SMI (SMD:-0.36;95%CI:-0.53--0.19). The smoker had higher MMA%(SMD: 0.22; 95%CI: 0.07 - 0.37) and lower DMA%(SMD:-0.16;95%CI: - 0.26 - - 0.05). The drinker had higher MMA% (SMD: 0.17; 95% CI: 0.07 - 0.27) and lower DMA%(SMD:-0.24;95%CI:-0.39--0.10). The older people had higher MMA%(SMD:-0.23;95%CI:-0.40--0.06). In addition, the body mass index may influence the percentages of MMA (SMD: - 0.18; 95% CI: - 0.31 - - 0.04, P < 0.01). Conclusion Arsenic exposure, smoking, drinking, and older age can reduce the capacity of arsenic methylation. Arsenic methylation is more efficient in women than in men.

Pigment epithelium-derived factor (PEDF) is an antiangiogenic factor which is effective in tumour inhibition in a variety of tumours and has not yet been studied in bladder tumour before. In this study the expression of PEDF, interleukin-1α (IL-1α) and -8 (IL-8) in bladder tumours was investigated. Immunohistochemistry was performed on 64 bladder tumour and 23 normal uroepithelium samples. Expression change of the factors was compared with clinicopathological parameters. Correlations between PEDF, IL-1α and IL-8 were analyzed. None of the factors was in relation to gender, tumour occurrence, and size or onset pattern. PEDF (P=0.014) and IL-1α (P=0.049) expression was down-regulated with grade progression. PEDF expression was lower in normal uroepithelium than in papillary urothelial neoplasm of low malignant potential (PUNLMP) (P=0.000) and carcinoma (P=0.009) whilst IL-1α (P=0.000 and P=0.000 respectively) and IL-8 (P=0.000 and P=0.023 respectively) expression was higher in the same grouping. PEDF expression had a negative correlation with IL-8 in PUNLMP (P=0.049, r=-0.578) as well as in tumour grouping (P=0.033, r=-0.276). Deranged expressional change of PEDF, IL-1α and IL-8 could be in relation to loss of differentiation from normal uroepithelium to papillary lesion and eventually to carcinoma.

Two endophytic-bacteria isolates of G18 and F19 were isolated from the stem of Taxus chinensis. The G18 and F19 were respectively classified into Psudomonas sp. and Stenotrophomonas sp. based on biological characteristics and 16S rDNA sequence analysis. The bioactivity analysis showed that the fermented broths of the G18 and F19 exhibited antagonistic activities against three pathogenic bacteria, and had good antagonistic effectiveness to Verticillium dahliae and Colletotrichum gloeosporioides, respectively. The G18 can degrade salicylic acid, and the F19 can do dichlorvos.
