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

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

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.

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.

0.05).There were no significant differences in thrombus-associated indexes except a slight change of plasminogen activator antigen.CONCLUSIONS:The incidence of DVT after tumor removal of urinary system is mainly associated with malignant tumor itself, operation wound, postoperative immobilization and the risk factors of thrombus,the administration of reptilase does not increase the incidence of DVT,but might promote the fibrinolytic activity of patients.

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.

Objective To evaluate the effects of reduced glutathione (GSH) on contractile and diastolic functions of the thoracic aorta of rats with obstructive jaundice.Methods Twenty-four adult male Sprague-Dawley rats,weighing 200-250 g,were randomly divided into 4 groups (n =6 each) using a random number table:sham operation group (group S),GSH group,bile duct ligation group (group BDL),and GSH + bile duct ligation group (group GSH + BDL).In GSH and GSH + BDL groups,GSH 300 mg/kg was infused via stomach everyday for 7 consecutive days,while the equal volume of normal saline was given in the other two groups.The common bile duct was ligated in the animals on 1 d after the end of intragastric administration in GSH and GSH + BDL groups.In GSH and GSH + BDL groups,after the model was established,GSH 300 mg/kg was infused via stomach everyday for 7 consecutive days,while the equal volume of normal saline was given in the other two groups.On 7th day after the model was extablished,blood samples were collected for determination of the levels of serum total bilirubin (TB),alanine aminotransferase (ALT) and aspartate aminotransferase (AST),tumor necrosis factor-alpha (TNF-α),interleukin-lβ (IL-1β) and 3-nitrotyrosine (3-NT),malondialdehyde (MDA),nitric oxide (NO) and GSH.The thoracic aortic rings were obtained and perfused with different concentrations of norepinephrine (NE),acetylcholine (Ach) and sodium nitroprusside (SNP).The maximum contraction and dilatation of aortic rings were recorded and the percentage was calculated.Some thoracic aortic rings were obtained again and perfused with different concentrations of NE after removal of the endothelium or after being perfused with L-NAME (nitricoxide synthase inhibitor).The maximum contraction of aortic rings was recorded and the percentage was calculated.Results Compared with group S,the serum levels of TB,ALT,AST,TNF-α,IL-1β,MDA,3-NT,NO and GSH were significantly increased in group BDL,and the serum levels of TB,ALT,AST,MDA,GSH and NO were increased in group BDL + GSH,the percentage of the maximum contraction amplitude of aortic rings in response to NE was decreased,and the percentage of the maximum dilatation amplitude of aortic rings in response to Ach and SNP were decreased in groups BDL and BDL + GSH,and no significant changes were found in the parameters mentioned above in group GSH.Compared with group BDL,the serum levels of TB,ALT,AST,TNF-α,IL-1β,MDA,3-NT and NO were significantly decreased,the level of GSH was increased,the percentage of the maximum contraction amplitude of aortic rings in response to NE was increased,the percentage of the maximum dilatation amplitude of aortic rings in response to Ach was increased,and no significant change was found in the percentage of the maximum dilatation amplitude of aortic rings in response to SNP in group BDL + GSH.Compared with the aortic rings from which the endothelium was removed or which were perfused with L-NAME in group BDL,no significant change was found in the percentage of the maximum contraction amplitude of aortic rings after removal of the endothelium or after being perfused with L-NAME in response to NE in group BDL + GSH.Conclusion GSH can improve the contractile and diastolic functions of thoracic aorta of rats with obstructive jaundice and this effect depends on the vascular endothelium.
