Objective To analysis effect of midazolam combined with etomidate on liver function, malondialdehyde(MDA) , superoxide dismutase (SOD) levels after laparoscopic cholecystectomy.Methods 80 patients who were undergoing laparoscopic cholecystectomy were collected,all patients were randomly divided into control group and experimental group, 40 cases in each group,who were given the appropriate anesthesia induction drugs before surgery.After operation,the serum levels of MDA, SOD, glutathione peroxidase(GSH-Px) and the liver function were detected in all patients. Results After operation, compared with control group, the serum alanine aminotransferase(ALT) , aspartate aminotransferase (AST) and total bilirubin (TBIL)levels were lower in the experimental group (P<0.05);the serum MDA level was lower in the experimental group (P<0.05);the serum SOD and GSH-PX levels were higher in the experimental group (P<0.05) .Conclusion Midazolam combined with etomidate can reduce oxidative stress reaction in patients after laparoscopic cholecystectomy, which is conducive to the recovery of liver function.

Objective To evaluate the merits and demerits of three different closure methods for femoral artery access site in the interventional therapeutic procedures for senile patients with coronary artery disease. Methods We managed the femoral artery access sites in 60 cases undergoing interventional operation using three different hemostasias, including manual compression, Femostop equipment and Perclose suture (20 cases for each group). The procedure time, time for patients staying in bed, expenditure obedience, the percentage of procedure failure and vagal vascular reflex, and local vascular complications were observed and analyzed statistically. Results The study showed that the procedure time in Perclose suture group was about 12 minutes, much shorter than that in finger pressing and Femostop equipment groups (respectively 23 and 55 minutes, P

Objective Implementing the scientific research performance evaluation indicator system constructed to evaluate the situation of scientific research performance conducted by two basic Departments during the 12th Five-Year period in a general hospital.To understand the practical applicability of the scientific evaluation index system,and also propose comments and suggestions based on the comparison between assessment score and actual research situation in the departments.Methods Based on the database of scientific research management information platform,collect related research data from two basic departments of the hospital in latest five years.Using SPSS software to conduct statistical analysis on the total score of the first and two indicators,as well as the specific indicators of the three indicators,according to the performance evaluation index system and the weight built by the hospital.Results The index system can basically reflect the general information of scientific research input and output in the department,however,some indicators cannot truly reflect the index importance and the differences between the index weight is not significant,so it is necessary to make amendment based on demonstration.Conclusions Hospital should dynamically update the index system to make them match the developing strategy of the hospital,also important to combine them with research stimulation to guarantee more scientific management and better service to the research development of hospitals.

A cDNA library was constructed from glands of wild Buthus martensii Karsch scorpion.A new sodium channel long-chain toxin BmkNaTx12 was identified by sequence alignment,and its full-length cDNA sequence was cloned.Sequence alignment showed that the sequence of BmkNaTx12 had high structural similarity with the β-toxin Cn12 from Mexican Centruroides noxius scorpion.The predicted structure of BmkNaTx12 was obtained by homologous model construction and the highest scoring model was selected.The protein structure was found to be stable at 300 ns by molecular dynamics optimization,and fluctuations at amino acids 20,35,and 52 are most like-ly due to the location of these amino acids in the loop region.Then,an expression system of recombinant BmkNaTx12-Fc fusion protein was constructed.The optimal expression time of recombinant protein was determined by Western blot and the fusion protein was successfully expressed in HEK293 cells.The purity of recombinant fusion protein which was obtained by protein A affinity chromatography was up to 95％ by SDS-PAGE gel electrophoresis and HPLC.In addition,the whole-cell patch-clamp assay results suggest that 1 μmoL/L BmkNaTx12-Fc can increase 20％ Nav1.7 peak current.These results laid a foundation for the further study of biological function.

Objective:To analyze the different expressions of miRNAs in peripheral blood of rheumatoid arthritis (RA) patients and the osteoclasts in rats,and to verify the key miRNAs in RA.Methods: The miRNAs expressions in monocyte and the co-cultured osteoclasts,peripheral blood of rheumatoid arthritis (RA) patients and normal were detected by miRCURYTM LNA Array.Real time PCR was applied to verify the reliability of miRNA array.The bioinformatics software and database were applied to predict and analyze target genes.Results: miRNA array results showed that 189 miRNAs changed in RA patients compared with the normal;211 miRNAs were changed in osteoclasts group compared with monocytes group.The expressions of ten miRNAs were all abnormal in RA patients and osteoclasts in rats.The results of Real time PCR were consistent with the array.Results of bioinformatics analysis showed that the target gene of miRNA significantly enriched in signaling pathways such as VEGF,MAPK signaling pathways.Conclusion: Some miRNAs had similar abnormal expressions in different species,and these miRNAs may influence the differentiation of the osteoclasts through regulating the related signal passways.

Objective To investigate the mechanism on JAK/STAT1 signal pathway in SAHA down-regulation of indoleamine 2,3-dioxygenase (IDO) in gallbladder carcinoma cells.MethodsWe treated gallbladder carcinoma SGC-996 cells with IFN-γ and SAHA.Western blotting was used to detect the expression of IDO,signal transducer and activator of transcription 1 (STAT1) phosphorylation and interferon regulatory factor genes-1 (IRF-1).Confocal microscopy analysis was used to detect STAT1 translocation.Transient transfections and reporter genes assay was used in detecting the activation of γ-activated sites (GAS) and interferon stimulated response elements (ISRE).ResultsIDO expressed in SGC-996 cells in dose- and time-dependent manners when stimulated with IFN-γ.SAHA down-regulated the expression of IDO induced by IFN-γ in a dose-dependent manner.SAHA blocked the expression of IRF-1 induced by IFN-γ.SAHA inhibited the IFN-γ-induced STAT1 phosphorylation and nuclear translocation.SAHA down-regulated IFN-γ-induced activation of GAS and ISRE.ConclusionsSAHA may down-regulate IDO expression through inhibiting the activation of members in JAK/STAT1 signal pathway.This may provide a new immunotherapeutic strategy to break tumor immune tolerance in gallbladder carcinoma.
