Objective To study the security in HBV carried infertility patients during the in-vitro-fertilization procedure. Methods Serologic testing of HBV infection (HBsAg, HBsAb, HBeAg, anti-HBe, anti-HBc-IgG) of blood, follicle fluid/sperm and fertilization culture medium/post-washing sperm in female/male carried patients were detected by ELISA on the day of oocytes collection. Results In 18 female patients who were seropositive for HBsAg, HBeAg and anti-HBc-lgG, the same antigen and antibody could be detected in all 18 folli-cle-fluid and fertilization culture medium(100%, 100%). In 131 female patients who were sernpesitive for HBsAg, anti-HBe, anti-HBc-IgG, the same antigen and antibody could be detected in 84 follicle-fluid(64. 1%), and 8 fertilization culture medium(6. 1%). If the patients'follicle-fluld was negative for all the markers, their fertilization culture medium remained negative. In 23 male patients who were sero-positive for HBsAg , HBeAg,and anti-HBc-lgG, the same antigen and antibody could be detected in only 6 sperm (26. 1%), all the postwashing sperm were exhibited negative. In 121 nude patients who were seropositive for HBsAg, anti-HBe, anti-HBc-lgG, the same antigen and antibody could be detected in only 7 sperm (5. 8%), and all the post-washing sperm were negative. Conclusion In IVF-ET procedures, the risk of HBV transmission by follicle-fluid and fertilization culture medium in those female patients who showed serepesitive for HBsAg , HBeAg, and anti-HBc-lgG can not be decreased. The risk in those female patients who showed seropositive for HBsAg, anti-HBe, anti-HBe-lgG and male patients in IVF-ET procedures can be decreased.

Objective To evaluate the value of cystography with low-concentration contrast medium in diagnosing small tumor of urinary bladder.Methods Cystography in 187 cases with bladder disease from 1992 to 2001 was performed using 6%～8% Meglumine Diatrizoate 100～120 ml under TV monitored.Radiogrames of A-P position and bilateral oblique position were taken when the focus was found.The radiogram on patient’s position at head low was adopted when necessary.Results Of 187 cases,106 cases of bladder tumors were detected,including 8 cases of small bladder tumor(≤1.0 cm in diameter),3 cases were misdiagnosed,the detectable rate was 73.0%.All cases were confirmed by operation and pathologiy.In these 8 cases,1 case was adenocarcinoma,5 cases were transitional epithelia cell carcinoma,2 cases were papilloma.The X-ray appearances were nipple-like or cauliflower shape with filling defect,a narrow pedicel could be occasionally found in papilloma or transitional epithelia cell carcinoma and it had somewhat movement when changed patient’s position.Conclusion Cystography with low-concentration contrast medium is a non-injury procedure in diagnosis of small tumor of urinary bladder.

Objective To compare the therapeutic effect of two Methodsof in vitro oocyte maturation (IVM) technology with polycystic ovary syndrome (PCOS) patients in infertility treatment.MethodsRetrospective analysis was performed on patients with PCOS infertility who were stimulated with two different kinds of stimulating method of the IVM cycle in our center during April 2010 and August 2010.There were 20 patients in the temporary FSH stimulating group (group A) and 31 patients in the HCG stimulating group (group B).The number of oocytes maturation rate,fertilization rate,cleavage rate,excellent embryo rate,implantation rate,pregnancy rate per oocyte recycle,pregnancy rate per transfer and abortion rate of transfer were compared.ResultsThere was no significant difference between the two groups of age,duration of infertility,body mass index,based sex hormone levels by t test(P＞0.05).There was no significant difference between the two groups of the number of oocytes retrieved,oocyte maturation rate,cleavage rate,and abortion rate of transfer(P＞0.05).In group B,the fertilization rate was 80.3%,good-quality-embryo rate was 49.8%,implantation rate was 31.5%,pregnancy rate per oocyte recycle was 54.8%,which was significantly higher than in group A (73.9%,35.4%,12.5% and 25.0%,respectively).ConclusionsIf IVM was used to treat PCOS patients with infertility,HCG stimulating will be better than FSH stimulating,and it could result in a higher clinical pregnancy rate.

ObjectiveTo confirm the effect of miR-93 inhibitor in glioma cell growth and invasion.MethodsMalignant glioma cells were transfected with miR-93 inhibitor by lipofectamin to downregulate their overexpression of miR-93.Real time-PCR was taken to measure miR-93 expression after transfection.The cell cycle kinetics and cell growth rate were detected by flowcytometry and MTT assay,the cell proliferative ability was evaluated by soft agar assay,and the invasive ability was detected by transwell assay.ResultsThe highlevel expression of miR-93 was downregulated effectively in glioma cells after transfecting the miR-93 inhibitor.Meanwhile,the cell cycle progress was delayed,S phase cells were reduced,the speed of growth was slowed,cloning formation ability was receded,the number of cells through the matrigel was reduced,and invasive ability was significantly repressed.ConclusionDownregulation of miR-93 expression could inhibit the proliferative ability and invasive ability of glioma cells.

Objective To develop a method for treating infertile women with polycystic ovary syndrome(PCOS)by ooeyte in vitro maturation(IVM).Methods On day 3～4 of menstrual cycle,infertile women with PCOS were administrated with(100～150IU)FSH/day for 3 days.On day 8～10,when the follicle diameter reached 10～14mm and endometrium＞5mm,the immature oocytes weFe picked up and cultured in vitro for 28～31 hours.Then,ICSI and embryo transfer were performed.Results 3 clinic pregnancies were established among 12 infertile women.the pregnancy rate was 25.0%.Conclusion This research indicates that IVM is a feasible technology for the infertile women with PCOS.

ObjectiveTo explore the best time for replacing the long-term indwelling catheter in patients with silicone catheter.MethodsDomestic literature were retrieved and analyzed using Cochrane systematic review,and the meta-analysis of randomized controlled trials was conducted in accordance with inclusion criteria and exclusion criteria so as to look into the most suitable time for replacing the indwelling catheter for patients with silicone catheter at clinical trials.The replacement frequency for the catheters of different size together with the relevant infections in urinary tract infection and relative risk(RR)were used as values for effectiveness of interventions.ResultsA total of 11 literature were retrieved. Meta-analysis results suggested that the RR values of urinary tract infections when the catheters were replaced once every two weeks vs. every four weeks,and once every three weeks vs. every four weeks were 0.51[95% CI(0.40,0.66),P <0.001],0.79[95% CI(0.58,1.08),P = 0.14],respectively.The urinary infection rate of replacing a silicone cathether every 2 weeks was higher than that of every 4 weeks,but there was no difference between that of every 3 weeks and 4 weeks.Conclusion According to the nature of silicone catheter material as well as the clinical indexes, it is most reliable to replace a silicone catheter every four weeks to reach a best clinical outcome.

Objective To investigate the effects of Rosa Laevigata Michx Flavoid( RLMF) and Rosa laevigata Michx Polysaccharose (RLMP) on expression of TRPV5 in IgA Nephropathy (IgAN) rat renal tissue. Methods Forty Sprague-Dawley rats were randomly assigned to four groups.The rat model of IgA nephropathy was induced by intragastric administration of bovine serumalbumin and injections of LPS and CC14.Eight weeks later,the rats with IgAN were treated with RLMF or RLMP (4 weeks), or normal saline.Rats was sacrificed at thirteenth weeks, and RNA was extracted from the kidney.Expression of TRPV5 in tubulointerstitial tissues were analyzed by fluorescent quantitative RT-PCR. Results After RFLP intervention,the expression levels of TRPV5 were markedly increased (P<0.01) than model control group,while decreased (P<0.05) than normal control group but had no significance with model control group after RFLF intervention. Conclusion TRPV5 expression is decreased in IgAN,and RLMP can adjust TRPV5 expression and improve renal function of IgAN.

Objective To study the inhibitory effect of knocking down miR-30a-5p on the U87 human glioma xenograft growth and its possible mechanism.Methods Nude mice bearing subcutaneous U87 human glioblastoma were established and separated into three groups (eight for each group) by randomized digital table method,including control group,scr-ODN treated group and AS-miR-30a-5p treated group.After relevant subcutaneous injection treatment,tumor size was measured every other day until the observation period ended.Researchers executed the animals after the treatment,stripped tumor tissues and extracted RNA and protein.Real-time PCR was conducted to detect the expression of miR-30a-5p.The histopathological characteristics and proliferation and apoptosis biological characters (including SEPT7,PCNA,cyclin D1,MMP-2,apoptosis related factor P53,bcl-2 and caspase3) were evaluated by HE and immunohistochemical staining,Westem blot analysis respectively,and the cell apoptosis was detected by TUNEL method.Results In AS-miR-30a-5p treated group,the tumor growth was delayed and the final tumor volume was smaller than that in the control and scr-ODN treated group (F =7.167,P ＜0.05),and the expression of miR-30a-5p was knocked down.The expression of PCNA,cyclin D1 were significantly downregulated while P53,SEPT7 and caspase3 up-regulated.Apoptotic index was increased significantly.Conclusion As-miR-30a-5p suppresses the growth of U87 human gliomas xenografts significantly.Malignant phenotype of tumors are reversed to a considerable degree.Therefore,miR-30a-5p can be a candidate for targeted therapy of human glioma.

Objective:This study aimed to explore the effect of Yes-associated protein (YAP) on the growth of the human glioma cell line LN229. Methods:YAPsiRNA was transfected into LN229 cells to knock down the YAP expression. The downregulation of the YAP expression was identified through Western Blot analysis. Colorimetric assay using methyl-thiazolyl-tetrazolium was applied to evaluate cell proliferation ability. Cell invasive activity was examined using Transwell assay. Flow cytometry and AnnexinV were used to detect cell cycle and apoptosis, respectively. The relevant molecules regulating proliferation, invasion, cell cycle progression, and apoptosis were examined through Western Blot analysis. Results:The YAP expression was downregulated after YAPsiRNA was trans-fected into LN229 glioma cells. Reduced YAP expression could arrest the cell cycle at G0/G1 phase, inhibit cell proliferation and inva-sion, and promote apoptosis. The expression of the proliferating cell nuclear antigen (Ki-67), matrix metallopeptidase-9 (MMP-9), cy-clin D1, and Bcl-2 were downregulated. Conclusion:The downregulation of YAP in LN229 cells suppresses cell proliferation and inva-sion, as well as promotes cell apoptosis. This study provides a novel evidence for further study on Hippo-YAP signal pathway in molec-ular pathology of glioma.
