ObjectiveTo evaluate the curative effect difference between Tong's anterior mesh suspension and modified tension-free vaginal tape-obturator (TVT-O). Methods75 SUI cases were random divided into two groups: Group A (35 cases) were accepted Tong's anterior mesh suspension and group B (40cases) were accepted modified tension-free vaginal tape- obturator. Curative effects, operation safety,and complications and so on, were recorded and compared. ResultsThere had no statistical differences between these two groups on operation time, bleeding lose, operation injury, immediate postoperative urinary retention andcure rates, but the operation expense of group A was cheaper than group B [ (980. 74 ±212.45)yuan vs (2879.06 ±467. 13)yuan , P ＜0.05). ConclusionThe curative effect between two methods were similar. It's a little complicated and fit to be popularized in large hospital to modified tensionfree vaginal tape-obturator. Tong's anterior mesh suspension was performed under completely direct vision,not through pelvic cavity, and it was an economic, convenient and easy way, which not only fit to be popularized in basic hospital, but also a surgical remedial measure to the failures who accepted these operations,such as TVT, SPARC, IVS, MONARC, TOT, TVT-O, etc.

Mesoporous silica nanoparticles as drug carrier have become the new hot point in the field of biomedical application in recent years. This review focuses on the more recent developments and achievements on experimental design aspect of mesoporous silica nanoparticles with cancer diagnosis and therapy. The key advances of functionalization strategies of mesoporous silica nanoparticles with controlled release, tumor targeting and overcoming multidrug resistance are discussed in particular. Mesoporous silica nanoparticles as unique delivery systems have the potential to provide significantly a sound platform for cancer theranostic application.

OBJECTIVETo study the cytotoxic T lymphocyte (CTL) response induced by dendritic cells (DC) transduced with recombinant adenovirus vector bearing hepatitis B virus surface antigen (HBsAg) gene in hepatocellular carcinoma HepG2. 2. 15 cells in vitro.

METHODSFull length HBsAg cDNAs were subcloned into pIND vector, followed by being cloned into pShuttle vector. The HBsAg gene fragments resulted from the pShuttle-S digested with PI-Sce and I-Ceu were linked to the linear adeno-X virus DNA. After packaged with HEK293 cells, the adenovirus expression vector was obtained. Then the recombinant adenovirus expression plasmid AdVHBsAg was transfected into human monocyte-derived dendritic cells, to construct AdVHBsAg hepatocarcinoma tumor vaccine. The effectiveness of transfection was detected by Western blot. Surface molecules of AdVHBsAg-DC were detected by FACS. Autologous T cell proliferation stimulated by AdVHBsAg-DC was detected by 3H-TdR assay. Cytotoxic CTL activity induced by AdVHBsAg-DC in vitro was detected by LDH assay.

RESULTSHBsAg gene in the inserted DNA of AdVHBsAg was confirmed by PCR, and predictive fragments proved by restriction enzyme digestion analysis were exhibited. Cell pathological changes appear after 10 days HEK293 cells transfected AdVHBsAg. Western blot analysis showed that HBV surface antigen gene was expressed in transfected DC, indicating that the transfection was effective. AdVHBsAg-DC was able to upregulate CD1a, CD11c, CD80, CD86 and HLA-DR. Autologus T cell proliferation induced by AdVHBsAg-DCs was significantly higher than that in DC control group and LacZ-DC group (P < 0.05). AdVHBsAg-DC activated CTL presented the specific killer ability to the hepatocellular carcinoma cells expressing HBsAg.

CONCLUSIONDC transduced with recombinant adenovirus HBsAg can express HBV-related hepatocellular carcinoma antigen (HBsAg), and AdVHBsAg-DC can induce potent immune response against HBsAg-positive hepatocellular carcinoma cells in vitro.

To investigate the effects of oleanolic acid (OA) on the proliferation, migration and the formation of tube-like structure in human vascular endothelial cells (HUVECs). MTT assay, flat plate scarification, Transwell plates and matrigel-induced tube formation assay were performed to detect the effects of OA on proliferation, migration and tube formation. MTT assay showed that the inhibition rates of HUVECs treated with 60 and 100 microg x mL(-1) of OA for 24 h were 19% and 83% respectively. Treatment of HUVECs significantly inhibited the cell migration in a dose-dependent manner. The vascular indexes of HUVECs treated with 40 and 60 microg x mL(-1) OA were 33% and 20% respectively. Western blotting analysis showed that treatment of the cells with OA significantly attenuated the expression and secretion of VEGF. Additionally, VEGF could in part reverse the effects of OA on migration and tube formation of HUVECs. In conclusion, OA inhibits the proliferation, and VEGF plays an important role in OA induced decreased migration and tube formation of HUVECs.

Objective To evaluate the association of cervical cancer and the G/C single nucleotide polymorphism at codon 72 in p53 gene exon -4 in Chinese population.Methods Literatures were searched in CNKI,VIP,CBM, PubMed,EMBase,the Cochrane Library (Issue 1,2015),WanFang Data Database (1980—2015)with computer. Results Thirteen studies involving 1 780 cervical cancer patients and 1 5 17 healthy volunteers were included.According to the situation of the HPV infection in research object,thirteen studies were divided into two subgroups.The results of meta-analyses in the subgroup of non-HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.980,95%CI:0.558 -1.723).The allele G showed no increased relative risk compared to the allele C (OR=1.070,95%CI:0.789-1.449)The results of meta-analyses in the subgroup of HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.891,95%CI:0.213 -3.722).The allele G showed no increased relative risk compared to the allele C (OR =0.981,95%CI:0.493 -1.951 ).Conclusion This meta -analysis demonstrates that G/C single nucleotide polymorphism at codon 72 in p53 gene exon-4 were not associated with cervical cancer in Chinese women.

OBJECTIVETo study the protective effect of recombinant adenovirus-mediated human cytosolic glutathione peroxidase (hCGPx) gene transfection on vascular endothelial cells ECV304 from oxidative damage.

METHODSpGEM-T Easy Vector containing hCGPx cDNA and recombinant adenovirus shuttle plasmid pACCMV-pLpA were used to construct the shuttle plasmid pACCMV-hCGPx for cotransfection of 293 cells with pJM17, thereby to obtain the recombinant adenovirus AdCMV-hCGPx. Cultured ECV304 cells were transfected with AdCMV-hCGPx for 24, 48 and 72 h, respectively, with the cells transfected with the empty vector serving as control, and hCGPx gene expression was then examined in the transfected cells. The transfected cell viability and apoptotic cell ratio were evaluated after treatment of the cells with H(2)O(2).

RESULTSThe expression ratio of hCGPx gene was significantly higher in the AdCMV-hCGPx-transfected cells than in those with empty vector transfection (P<0.01). The hCGPx gene-transfected cells showed significantly higher viability and significantly lower apoptotic ratio than the control cells following challenge with H(2)O(2)-induced oxidative damage.

CONCLUSIONhCGPx gene transfer mediated by recombinant adenovirus protects the vascular endothelial cells from oxidative damage in vitro, possibly due to the antioxidative and apoptosis-inhibiting effect of hCGPx.
