Objective To construct recombinant Bb-Em14-3-3 vaccine of Echinococcus multilocularis and to investigate expression efficiency of Em14-3-3 antigen encoding gene in Escherichia coli BL21(DE3).Methods Em14-3-3 antigen gene was amplified by PCR.Then the gene was cloned into Escherichia coli-Bifidobacteria shuttle plasmid pGEX-1? T containing gluathione-S-transferaze(GST) gene to construct pGEX-Em14-3-3.The recombinant plasmid was electroporated into Bifidobacteria bifidum(Bb) to construct rBb-Em14-3-3 vaccine.The vaccine was identified with PCR and restriction-endonuclease digestion.The expression of pGEX-Em14-3-3 was induced with isopropyl-?-D-thiogalactopyranosid(IPTG) and fusion protein Em14-3-3/GST was examined by SDS-PAGE and Western blot techniques.Results 530 bp gene of Em14-3-3 was successfully amplified by PCR and cloned into pGEX-1? T by restriction analysis.rBb-Em14-3-3 vaccine was successfully constructed by PCR and restriction-endonuclease digestion.It was demonstrated with SDS-PAGE and Western blot that the fusion protein Em14-3-3/GST was expressed in E.coli,BL21.The expression efficiency is 23%.Conclusion rBb-Em14-3-3 vaccine of Echinococcus multilocularis was successfully constructed.The plasmid pGEX-Em14-3-3 was highly expressed in E.coli in fused form with GST and this kind of protein shows specific antigenicity.

Objective To study the value of echocardiography in diagnosis of prenatal closure of fetal ductus arteriosus(FDA) and discuss its characteristics. Methods Two cases with prenatal closure and one case with constriction of the FDA were examined.The echocardiographic characteristics were analyzed and the literature was reviewed. Results Right atrial and ventricular dilatation and severe tricuspid valve insufficiency were observed. After timely delivery, impaired right ventricular function improved significantly. Conclusions Fetal echocardiography plays an important role in diagnosis of prenatal closure of the FDA.

Objective To investigate the inhibitory effect on enhancement of contraction and relaxation functions of cardiomyocytes induced by of MN9202 TEA, Forskolin, and MB. Methods The twitch amplitude was measured with a video edge tracker method. The following indexes, including ph (peak height), peak height/baseline percent (ph/bl, %), maximal velocity of contraction (+dL/dt) and maximal velocity of diastolization (-dL/dt), were recorded by a computer. Results TEA, Forskolin and MB increased electrically-induced contraction as shown by the following indexes: ph, ph/bl%, +dL/dt and -dL/dt. Forskolin and MB markedly augmented function of cardiac myocyte contraction and diastolization. Comparing with the control group, Forskolin (10-8mol/L) increased ph from 0.12?0.03(um)to 0.24?0.06 (um), ph/bl % from 12?3% to 27?6%, +dL/dt from 1.8?0.5 (um/s) to 3.8?0.9 (um/s), -dL/dt from 1.8?0.22 (um/s) to 3.5?0.7 (um/s). These indexes increased by 91%, 123%, 110% and 89%, respectively. MB also increased significantly; ph, ph/bl %, +dL/dt and -dL/dt were 0.14?0.04um, 11?4%, 2.2?0.3um/s and 2.2?0.6um/s, respectively. MN9202 (3?10~ -6mol/L) decreased the indexes (+dL/dt and -dL/dt ) which were increased by Forskolin significantly. Conclusion TEA, Forskolin and MB increased function of cardiac myocyte contraction and diastolization. These drugs might elevate intracellular calcium content indirectly and directly. The effects of TEA, Forskolin and MB were attenuated by MN9202. MN9202 might not only block Dihydropyridine Receptor, but might also inhibit calcium influx. Further study is needed to elucidate exact mechanism of MN9202.

Objective:To summarize the drug repercussion data in outpatient pharmacy and analyze the reasons to provide sugges-tions for the improvement. Methods: The information was collected from the hospital information system ( HIS) during January 1, 2013 and December 31, 2015, including drug name, category, quantity, amount, reasons for drug repercussion and the other statisti-cal data. Results:During the three years, the number of prescription drugs, amount of money and varieties of drug repercussion were increased. The most common reasons for drug repercussion were the other reasons, withdrawn by doctors and the request of patients. The sum of drug repercussion was positively correlated with the drug price and the amount of drug repercussion. Conclusion:The op-tion simplicity for drug repercussion in HIS is the main reason for drug repercussion bythe other reasons. The occurrence of drug re-percussion should be intervened by such methods as gradually improving the HIS, establishing intervention measures, enhancing the professional quality of pharmacists and so on.

Objective To evaluated the effect of first-line epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)on advanced non-small cell lung cancer (NSCLC)patients with different EGFR mutation status (exon 1 9 deletion and exon 21 mutation).Methods Seventy-two advanced NSCLC patients with EGFR mutation confirmed by histopathology were enrolled.All of the patients received first-line EGFR-TKI.The relationships between EGFR mutation status and objective response rate (ORR),disease control rate (DCR),progression free survival (PFS ) and overall survival (OS ) were analyzed.Results Of the 72 patients,37 patients expressed exon 1 9 deletion,35 patients expressed exon 21 mutation,and all of them could be evaluated.The ORR and DCR of patients with exon 1 9 deletion were higher than those of patients with exon 21 mutation (75.7%vs.51 .4%,χ2 =4.583,P=0.032;89.2%vs.68.6%,χ2 =4.636,P=0.031 ).The modified median PFS of patients with exon 1 9 deletion was significantly higher than that of patients with exon 21 mutation (1 3.2 month vs.1 0.8 month,χ2 =4.700,P=0.030).The median OS of patients with exon 1 9 deletion was significantly higher than that of patients with exon 21 mutation (30.2 month vs.25.6 month,χ2 =4.686,P=0.030).The side effects were similar between the two groups.The most common adverse reaction was rash,and the incidence had no significant difference between the two groups (48.7% vs.48.6%,χ2 =0.000,P=0.995 ).Conclusion EGFR mutation status is a predictor for PFS,OS and ORR of first-line EGFR-TKI in patients with advanced NSCLC.NSCLC patients with EGFR exon 1 9 deletion are associated with longer survival time and better response rate compared with those with exon 21 mutation.

Objective To investigate the prognostic factors of life and functional outcome of the first hemiparetic stroke patients. Methods One hundred and eighteen stroke subjects were registered prospectively. The Barthel index (BI) , Rankin scale (RS) , Mortricity index(MI) , Mini-mental state examination (MMSE) , Montgomery-Asberg depression scale (MADRS) and a scale of general state and risk factors were used to evaluate at the 48th hour, the 15th day and the 90th day after stroke. Results The patients' performance, as demonstrated by their scores with all the evaluation instruments, changed significantly at all the time points of evaluation after stroke (P ＜0.05). There was no significant difference between the performance at the 48th hour and the 15th day after stroke ( P ＞ 0.05 ). But at the 90th day after stroke, the activity of daily living performance and the depression status recovered significantly (P ＜ 0.01 ). Logistic regression analysis showed that, such factors as pneumonia, urinary incontinence within 48th hour and deep sensation disturbance might adversely influence patients' activity of daily living performance at the 90th day after stroke; the muscle strength of upper extremities at the 48th hour, and MMSE scores at the 15th day after stroke acted as the protective factors. Conclusions The stroke patients improved significantly with regard to their clinical and functional manifestations when evaluated 90 days after stroke onset. The main factors influencing the activity of daily living performance 90 days after stroke onset included deep sensation disturbance,pneumonia, urinary incontinence and muscles strength of upper extremities at 48th hour, and MMSE scores at the 15th days after onset.

Objective:To evaluate the uncertainty in carbamazepine ( CBZ) determination in human plasma by HPLC-MS/MS. Methods:The whole process of CBZ determination was analyzed and the uncertainty sources were established, and then the uncertainty was evaluated and combined, and the expanded uncertainty was also calculated. Results: The expanded uncertainty of CBZ with low (7.46 ng·ml-1) and high (745 ng·ml-1) levels was 0.410 ng·ml-1 and 33.400 ng·ml-1, respectively (P=95%, k=2). Conclusion:The uncertainty in CBZ determination in human plasma by HPLC-MS/MS is mainly caused by recovery, sample prepara-tion and matrix effect for low concentration, and by sample preparation and repeatability for high concentration.
