Purpose:Evaluate the prognostic factors in invasive vulvar cancer.Methods:Fifty one cases with invasive vulvar cancer admitted in our hospital from 1980 to 1999 were retrospectively analyzed.Results:Thirty six patients had squamous cell carcinoma and 27 of them were well differentiated and 6 moderately differentiated and 3 poorly differentiated ,three had adenocarcinoma, three had basal cell carcinoma ,three had leimyosarcoma , six had malignant melanoma. Thirteen cases (25.4%) were in FIGO stage Ⅰ;29 (56.7%) in stage Ⅱ;7(13.1%) in stage Ⅲ and 2(3.9%) in stage Ⅳ. The 5-year survival rates of stage Ⅰ,Ⅱ,ⅢandⅣwere 81.5% , 68.4% , 41.2% and 0.0% (P

Objective:To construct a EGFP(Enhanced green fluorescent protein)-labled euk-aryotic expression plasmid of Fcy::Fur suicide gene and to detect its expression in SKOV3 cell line. Methods:With the technology of gene re-arrangement,Fcy::Fur gene in pORF-Fcy:Fur plasmid was subcloned into pEGFP-N1 vector,with its correctness evaluated by the means of r-estriction enzyme analysis and sequencing.It was transfected into SKOV3 cells with lipofectin,the transient expression of GFP was observed under flu- orescence microscope after 24 hours and detected by Western blot. Results:Correct construction of pEGFP-N1-Fcy::Fur was identi- fied by methods of restriction enzyme analysis and nucleotide sequence determination.A total of 60% transfe-cted cells emitted out green fluorescence under fluorescent microscope after 24 h after transfecti-.on. Fcy::Fur gene expressed by the transfected cells were testified by Western blot. Conclusion:The recombinant eukaryotic expression vectors have been constructed successfully and effec- tive-ly expressed in ovarian cancer cells,which may provide an experimental basis for gene therapy of ovarian cancer.

Objective To explore the relationship between antibiotic application time and delivery outcome after the premature rupture of membranes,and to explore the effect of using antibiotics to delivery outcome.Methods 474 premature rupture of fetal membranes parturient who deliver in our desk work were selected as study objects.According to the time of premature rupture of membranes,the patients were dividwd into groups.The patients that bear children within 12h after the membrane rupture are divided into A group.A group had 284 cases and they were randomly divided into two groups,A1 group and A2 group,both of which had 142 cases.The patients that beared children within 12 ～ 24h after the membrane rupture were divided into B group.B group had 120 cases.The patients that beared children 24h after the membrane rupture were divided into C group.C group had 70 cases.A2 group,B group and C group were all given antibiotic intravenous infusion,A1 group was not given that.The pregnancy outcome was observed.Results B group and A group,C group and A group had significant differences in the mode of delivery,fetal distress,neonatal asphyxia,chorioamnionitis incidence (all P ＜ 0.05).A2 group and A1 group had no significant differences in the mode of delivery,fetal distress,neonatal asphyxia,chorioamnionitis incidence (all P ＞ 0.05).Conclusion If there are clear evidence which can prove maternal have infected within 12h after the membrane rupture,we can choose not to use antibiotics.And whether using antibiotics or not can not affect the delivery outcome.

Brain tumor stem cells (BTSCs) play a key role in tumorigenesis and tumor development.There are a group of special markers in the surface of brain tumor stem cells,which can sorts stem cells,precursor cells and cancer stem cells.In recent years,the studies of CD133,Nestin,high-mobility group A1,A2B5 have made some breakthroughs.

Objective To investigate the clinical effect of cefoperazone sodium and sulbactam sodium. Methods 56 cases who used cefoperazone sodium and sulbactam sodium for anti -infection were selected as the observation group,and 56 hospitalized patients who used cephalosporin ceftazidime were selected as the control group. The observation group was intravenously injectioned cefoperazone sodium and sulbactam sodium,the control group received intravenous ceftazidime.The clinical efficacy and adverse reactions of the two groups were compared.Results After treatment,the cure rate and total effective rate of the observation group were 55.36%,98.21%,which of the control group were 35.71%,91.07%.The cure rate of the observation group was significantly higher than that of the control group (χ2 =4.356,P <0.05),and the total effective rate between the two groups had no statistically signifi-cant difference (χ2 =2.817,P >0.05).The incidence rate of adverse reactions of the two groups had no significant difference.Conclusion Cefoperazone sodium and sulbactam sodium therapy has good clinical efficacy in the treat-ment of infectious diseases,and has low incidence of adverse reactions,good safety,which can be popularized and applied in clinic.

With the deepening of the lung cancer molecular biology research,small molecular targets antitumor drugs make breakthrough progress,the epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is one of the most attention drug.A series studies show that EGFR-TKI can enhance the antitumor activity of ionizing radiation.Therefore,EGFR-TKI combined with radiotherapy alone for poor-risk patients appears survival benefit,but can't ignore the lung toxicity.However,there is a big contro-versy that EGFR-TKI combined with chemoradiotherapy for locally advanced NSCLC.

Epstein-Barr Virus (EBV) is the first human virus related to oncogenesis.EBV infection is associated with inflammatory bowel disease (IBD) with unknown causality.The prevalence of EBV in intestinal tissue from patients with IBD is significantly higher and related to the exacerbation of the disease and refractory IBD.Immunosuppressive therapy has improved outcomes associated with IBD.However,it is also associated with an increased risk of opportunistic infection,and lymphoproliferative disorders (LDs) maybe due to EBV infection.Here we review our current understanding of the pathogenesis of EBV infection in colonic mucosal inflammation,EBV-induced disease exacerbation,lymphomagenesis in IBD,and clinical approaches therefrom.

Objective To explore NF-κB(P65)expression in breast cancer and its clinical significance.Methods Immunohistochemical staining was used to examine the expression of NF-κB(P65)and its relationship with related elinicopathological factors were analyzed in eighty-seven IDC(invasive ductal cancinoma).Results NFκB(P65)expression was significantly correlated with lower tumor grading,maxilary lymph node metastasis,later TNM styng and HER-2 positive(all P＜0.05),but not with tumor size,age of the patient and the state of ER、PR.Conclusion NF-κB(P65)should be risk factors of poor prognosis in IDC.

Objective To study the effect of rosiglitazone (RSG), the agonist of peroxisome proliferator activated receptor γ (PPARγ), on the proliferation and differentiation of rat osteoblasts and the related mechanisms. Methods The identification of rat primary osteoblasts was performed by alkaline phosphatase (ALP) staining and mineralized nodules. The 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay and p-nitrophenyl phosphate (PNPP) assay were used to observe the effects of different concentrations of RSG on proliferation and differentiation of the osteoblasts. The reverse transcription polymerase chain reaction (RT-PCR) were used to detect the expression of connective tissue growth factor (CTGF) mRNA. The effects of the different concentrations (0,1,2,5,10 and 20 μmol/L) of RSG on TGF-β1-induced CTGF mRNA expression in osteoblasts were detected. Results (1)Different concentrations of RSG could not change the proliferation of osteoblasts (P＞0. 05). (2)Compared with control group, all different concentrations of RSG could suppress ALP activity in osteoblasts (P＜0. 01 ). (3) RSG suppressed the osteoblats CTGF mRNA expression induced by TGF-β1 in a dose-dependent manner (P＜0. 01). Conclusions In vitro, RSG can inhibit the TGF-β1 induced rat osteoblasts CTGF mRNA expression. RSG may play a potential role in preventing the differentiation of the rat osteoblasts.
