Objective To determine whether the maternal serum interleukin-6(IL-6)and in- terleukin-8(IL-8)concentrations can be used in the antenatal diagnosis of intrauterine infection in premature rupture of membranes(PROM).Methods The level of maternal serum IL-6 and IL-8 were determined by a sensitive enzyme-linked immunosorbent assays in 50 normal late pregnant women,25 patients with PROM but without evidence of IAI and 49 patients with PROM and IAI. Results The maternal serum IL-6 and IL-8 concentrations in patients with PROM and IAI were 301.19?142.34/L and 312.32?149.56 ng/L,which were higher than that in patients with PROM but without IAI(133.22?55.26 ng/L and 125.35?61.30 ng/L)and the normal late pregnant wom- en were(126.59?57.12 ng/L and 112.69?56.02 ng/L),P

Objective To investigate the sedative effects and the adverse reactions in the elderly patients received different speed of dexmedetomidine (Dex) intravenous infusion. Methods Eighty elderly cases were randomly divided into four groups. Group D0 was the control group, while the group D1, D2 and D3 were the trial groups. The heart rates, blood pressure, SpO2, Ramsay sedation score and Narcotrend value were recorded. Results The sedation onset time of the D2, D3 group was faster than those in the D0 and D1 groups (P <0.05, respectively), and the duration of sedation in groups D2 and D3 were significantly longer than that in the D0 and D1 groups (P < 0.05). Among the four groups, no significant differences in the incidence of hypotension or bradycardia needed vasopressors or atropine to treat and oxygen saturation were shown (P > 0.05). Conclusion Intravenous infusion of Dex by doses of 0.75 ~ 1.0 μg/(kg·h) during hip surgery in the elderly patients under spinal anesthesia could lead to a safe and effective sedation.

Objective Sodium-bile acid cotransporter plays an important role in the development of Echinococcus.The present study aimed to clone sodium bile acid cotransporter gene in Echinococcus multilocularis (EmSBACT5) and to analyze the bioinformatics of its coding protein.Methods EmSBACT5 gene was amplified by reverse transcription RCR (RT-PCR) technology and its nucleotide sequence was sequenced.Bioinformatics softwares were used to predict and analyze the physical and chemical properties, hydrophilicity/hydrophobicity, transmembrane domain, post-translational modification sites, structural domain, secondary structure, tertiary structure, subcellular localization and biological functions of the coding protein.Results The complete open reading frame was amplified with 654 bp in length, encoding 217 amino acids.The homology of the nucleic acid sequence and amino acid sequence of EmSBACT5 gene were 98% and 96% with the published SBACT5 in Echinococcus granulosus (EgSBACT5) respectively.Protein analysis results showed that the molecular formula of EmSBACT5 protein was C1141H1797N273O284S11.Its relative molecular mass was 24240 and isoelectric point was 8.99.There were 9 post-translational modification sites and 4 typical domains.Alpha helical, β-sheet, β-turn and random coil accounted for 29.95%, 31.80%, 7.83% and 30.41%, respectively.This protein was a hydrophobic membrane protein and was mainly located in the cytoplasmic membrane, and it might play a role in the processes of material transport and signal transmission.Conclusion The EmSBACT5 gene was cloned successfully and the informatics characteristics of its coding protein were obtained, which provides basic information for prevention and control of echinococcosis.

Objective To evaluate the inhibitory effects of gefitinib on the growth of colon carcinoma cells with different degree of sensitivity,and the activated status of epidermal growth factor receptor(EGFR) associated signal pathway proteins.Methods The colon carcinoma cell lines(Lovo,HCT116 and HT29) were treated with 10?mol/L of gefitinib,and flow cytometry was employed to detect the cell cycle and apoptosis.Another portion of cells were treated with 50ng/ml of epidermal growth factor(EGF) or 5?mol/L or 10 ?mol/L of EGF+gefitinib,and Western blotting was used to determine the expressions of PTEN,EGFR,AKT and MAPK,as well as their corresponding phosphorylated proteins,p-EGFR,p-AKT and p-MAPK.Results After being treated with gefitinib,the G1 phase cells and apoptosis rate increased remarkably in Lovo,slightly in HT29,while no significant change was found in HCT116.With the treatment of EGF alone,the expressions of p-EGFR,p-AKT and p-MAPK increased significantly in Lovo and HT29 cells(P0.05).Conclusions The growth of colon carcinoma cells,which are resistant to gefitinib,is not dependent on EGFR,and the activated status of signal pathway of the gefitinib-resistant cells will not be inhibited as the EGFR is blocked.The present findings suggest that sensitivity of colon carcinoma cells to gefitinib relies on EGFR as well as the activation of its downstream signal pathway.

Objective To investigate the relationship between the sensitivity of colon carcinoma cells to epidermal growth factor receptor(EGFR) inhibitor,gefitinib,and the downstream proteins of EGFR.Methods The expressions of EGFR proteins of 6 colon carcinoma cell lines(Lovo,HCT116,HT29,LS174T,SW480 and SW620) were determined with immunocytochemistry staining.The inhibitory effects of gefitinib on the growth of colon carcinoma cells were assessed by MTT,and the expression levels of Akt and MAPK as well as their phosphorylated forms(p-Akt and p-MAPK) were assessed by Western blotting.Results EGFR protein expressed in all the Lovo,HCT116,HT29,LS174T and SW480 cells,and the highest expression was found in Lovo cells,but not in SW620 cells.Lovo cells showed the highest,HT29 and SW480 cells showed moderate,sensitivity to gefitinib,while the others showed more or less resistance to gefitinib.No significant difference was found between the growth inhibition and IC50 values among the 6 cell lines despite of being treated with fetal bovine serum or EGF.Akt protein existed in all the cell lines without notable difference.Lovo and SW620 cells showed the least of p-Akt expression(P

Objective To investigate the correlation between XRCC1 R280H,XRCCl TSS+29C/T genetic polymorphisma and susceptibility to non-Hodgkin lymphoma (NHL). Methods The MassARRAY method was applied to detect the DNA repair gene XRCC1 genetic polymorphisms in 73 cases of NHL and 540 cases of normal healthy controls. Chi-square test was performed to calculate the adjusted odds ratios (OR) and 95% confidence intervals (CI). Results For XRCCl R280H genotypes, there was a significant difference between frequencies of the G and A among patients and controls (P=0.001). However, XRCCl TSS+29C/T genotypes had no statistical difference as for the T and C frequencies between patients and controls (P = 0.383). The frequency of XRCCI R280H with at least one A genotype was lower in the NHL cases than in controls, indicating a decreased risk for NHL development (OR=0.309, 95 % CI =0.168-0.567), comparing with GG genotype. In XRCC1 TSS+29C/T genotypes, the frequeney of TC and CC genotype was higher in NHL cases than in controls and associated with an increased risk of NHL development (P=0.472, OR =1.262, 95 % CI =0.669-2.379). Conclusion DNA repair XRCCl gene possesses significant correlation with NHL.
