0.05);the frequencies of IFN-? gene +874 site T and A allele showed significant difference between case group and control group(P0.05).Conclusion T allele of IFN? gene+874 site might have a relationship with generation of ovarian cancer,TT genotype might be susceptibility genotype for ovarian cancer.

Objective To investigate the association between polymorphism of protein C inhibitor(PCI)gene G10877T and male infertility,and provide theoretical basis for treatment of male infertility.Methods PCR and sequencing technique were applied to detect PCI gene G10877 T polymorphism in 53 normal control and 102 male infertility.Results There were three genotypes of wild type(G/C),hybridization mutation(G/T)and pure mutation(T/T).The analysis of sequencing indicated that in sperums of a proportion of the male infertile patients,TGG in PCI gene G10877T mutated into TGT.The contrast of BLASTB indicated that this mutation made Trp in 271 position change into Cys.Compared with control group,TT genotypic frequency and T allelic frequency in male infertility group had significant differences(P

60 yr, hypertension, diabetes mellitus, smoking, long term inactivity etc), and duration of operation. The incidence of DVT was 49.3% in control group, 30.0% in group CS alone, 15.0% in group CS + IPC1 and 23.3% in group CS + IPC2 (P

Object To explore the relationship of 25 (OH) D levels in cord and maternal peripheral blood to understand the maternal and neonatal vitamin D status in Songjiang District of Shanghai. Methods One hundred newborns delivered at the First People’s Hospital afifliated to Shanghai Jiaotong University and 20 pregnant women during November 2010 to January 2011 in Songjiang district were enrolled in the study. The levels of 25 (OH) D in cord and maternal blood were measured by ELISA and compared. Results Mean materna1 serum levels of 25 (OH) D was (23.42±5.23) nmol/L, and cord blood 25 (OH) D was (29.77±12.51) nmol/L. Maternal serum 25 (OH) D was positively correlated with cord blood 25 (OH) D (r=0.84, P<0.001). Conclusions This study shows that the prevalence of vitamin D deifciency in pregnant women is high in Shanghai Songjiang District, which could have adverse effects on newbowns.

Objective To analyze the expression stability of the three widely used reference genes β-glueuronidase (GUSB), glycera]dehydes-3-phosphate dehydrogenase (GAPDH), β2-microglobulin (β2-M) in Chinese lung cancer tissue specimens and normal lung tissue specimens. Methods Gene expression wasmeasured by quantitative real time PCR and expression stability was analyzed with two widely used softwares genorm and normfinder. Results The intra-and inter-group difference of GAPDH is maximum (The intra and inter-group s is 1.07 and 0.93 respectively, |△ Ct|=2.01±1.06; P =0.000). The mean of these three genes' Ct value is the most stable one analyzed by the two softwares. But the t test showed that the mean of Ct value of GUSB and β2-M is the unique combination that had the minimum intra-and inter-group difference, with no statistically significant differences between normal and malignant samples (The intra-and inter-group s is 0.53 and 0.79 respective]y, |△Ct|= 0.73±0.53; P =0.053). Conclusion It is inappropriate to normalize data derived from lung tissue specimens using one of these three housekeeping genes alone. Among the different combinations of these three genes, the mean of the Ct values of GUSB and β2-M is the best choice as the internal control of lung tissue specimens.

Objective To explore the efficacy of calmodulin antagonist berbamine(BBM)on multidrug resistance(MDR)reversal and its mechanism. Methods Human breast cancer cell line MCF7 and its adriamycin-resistant counterpart MCF7/ADR were used in the study.The cells were cultured with ADR and different concentration of BBM. MTT assay was used to analyze the effect of BBM on cell growth inhibition.According to the MTT assay,the 50% inhibitory concentration(IC 50 ),the multiples of drug resistance and increased sensitivity of ADR were calculated.The concentration of intracellular ADR and expression level of P-glycoprotein(P-gp)were detected by flowcytometry(FCM).The mRNA expression level of mdr1 gene was detected by semi-quantitative reverse transcriptase polymerase chain reaction(RT-PCR)with ?-actin as internal reference. Results The IC 50 of ADR in MCF7 and MCF7/ADR cells were(0.98?0.06)?mol/L and(101.20?5.72)?mol/L,respectively.The resistant multiple of MCF/ADR cells to ADR was 103 folds higher than that of MCF7 cells.BBM increased the chemo-sensitivity of ADR in MCF7/ADR cells with dose-dependent relationship,i.e.when 5*!?mol/L ,10*!?mol/L and 20*!?mol/L BBM was added into the culture the chemo-sensitivity of ADR was increased to 2.76,5.88,and 28.26 folds(P

Objective To study the genes which simultaneously participate in different carcinogenesis progression in lung adenocarcinoma for biomarkers identification. Methods 10 lung adenocarcinoma samples including pathologic stage Ⅰ,Ⅱ,Ⅲ were chosen for experiment and their matched normal tissues for control. After hybridization on 20 slides of microarray with 13824 genes, we analyze the expression profiles combined with pathologic stage and clinical prognosis by data mining. The genes differentially coexpressed in different stage and different prognosis samples were the target. Results 119 genes were identified. Among these targets, 26 genes have known to be related to lung cancer, 46 genes were unreported and 47 gene were new. Conclusions The 119 genes were very important during cancer occurrence and development and were the candidate biomarkers in lung adenocarcinoma.

Objective To analyze the relationship between leukocyte function-associated antigen-1 (LFA-1) mRNA expression and corneal inflammation and discuss the inhibition reaction of nuclear factor-?B(NF-?B)inhibitor on LFA-1 mRNA expression.Methods The corneal suture or combined with subconjunctival injection models were constructed in BALB/C mice.The corneas of each group were excised 1,3,7 and 14 d after operation and LFA-1 mRNA expressions were investigated by reverse transcription polymerase chain reaction(RT-PCR).Results At 1,3 and 7 d after operation, the expressions of corneal LFA-1 mRNA in corneal suture combined with lipopolysaccharide (LPS) (corneal suture+LPs)subconjunctival injection group were higher than those in corneal suture group (P0.05).At 1 and 7 d after operation, compared with corneal suture+LPS group ,the expression of corneal LFA-1 mRNA increased,but it decreased at 3 and 14 d after operation in the group of corneal suture combined with LPS and pyrrolidine dithiocarbamate (PDTC) (P

Objective To study the effect of sanguinarine on the growth and radiosensitivity of ovarian cancer SK-OV-3 cells.Methods Cell growth was determined by MTT and clonogenic assay.Cell cycle analysis was performed by flow cytometry assay.The cell apoptosis was analyzed by Annexin V/PI assay.Results Sanguinarine inhibited SK-OV-3 cell growth in a dose-and time-dependent fashion and its IC50 values were 3.02 and 1.11 μmol/L at 24 and 48 h,respectively. Sanguinarine also significantly triggered a sub-G1 peak,an indicator of apoptosis,and caused a G0/G1 arrest.Furthermore,the cell apoptosis induced by X-irradiation was significantly increased at 6 Gy when the cells were pre-treated with sanguinarine,in which the early apoptotic population increased from 10.28％ to 43.28％ (t =19.41,P ＜0.01 ) and the late apoptotic population increased from 20.26％ to 30.80％ ( t =8.78,P ＜ 0.01 ).The multi-target click model was used to fit survival curves and the SER of sanguinarine treatment approached to 1.625 at the dose of D0. Conclusions Sanguinarine could inhibit SK-OV-3 cell growth by inducing apoptosis and cell cycle arrest and enhance cell radiosensitivity at low doses.
