Objective To obtain recombinant human granulysin using prokaryotic expression system. Methods Total RNA was extracted from cultured PBMC. Granulysin gene segments were obtained with granulysin-specific primers by RT-PCR and then inserted into pET32a(+) plasmid. After identification by DNA sequence, pET-GN-LY9K and pET-GNLY15K were transferred to E. Coli Rosetta (DE3). The fusion protein was identified by SDS-PAGE and Western blot. The bioactivity of granulysin fusion protein was measured by MTT assay. Results The prokaryotic expression vectors pET-GNLY9K and pET-GNLY15K were successfully constructed. The corresponding protein was highly expressed in E. Coli. Recombinant protein was specifically bound by anti-granulysin antibody. GNLY9K fusion protein significantly inhibited the growth of A549 cells in a dose-dependent manner, while GN-LY15K had little effect on the growth of A549. Conclusion Granulysins with different mw were successfully expressed using prokaryotic expression system, which might be helpful for the further study of granulysin.

Objective To investigate clinical effect and mechanism of Yudanrongxin pills in the treatment of patients with acute myocardial infarction ( AMI) .Methods 86 cases of AMI in our hospital from February 2014 to February 2015 were selected and divided into the observation group and the control group, with 43 cases in each group.The patients in the control group were treated with conventional therapy, while patients in observation group were treated with Yudanrongxin pills on the basis of the control group.The related inflammation factors, indicators of myocardial injury and heart function index were compared between two groups before and after treatment.Results Compared with before treatment, in both two groups after treatment, the serum inflammatory factors including high-sensitivity C-reactive protein(hs-CRP), IL-6,soluble vascular cellular adhesion molecule-1 (sVCAM-1), TNF-αand P-selectin decreased, the myocardial injury criterion including creatine kinase-MB (CK-MB), lactate dehydrogenase (LD), myocardial troponin I (cTnI) and myoglobin (Mb) decreased,the cardiac function indexes of left ventricular end systolic volume (LVESV) and left ventricular end diastolic volume (LVEDV) decreased and left ventricular ejection fraction (LVEF) increased (P<0.05).Compared with control group, the hs-CRP,IL-6,sVCAM-1,TNF-α,P-selectin,CK-MB,LD,cTnI and Mb in observation group were lower(P<0.05).The degree of improvement at cardiac function was better than that in control group (P<0.05).Conclusion Yudanrongxin pills could better improve cardiac function in treatment with AMI, its role was relative to inhibition of inflammatory factors and myocardial protection against injury.

Objective To investigate the relationship between the expression of glucose regulated protein 78 (GRP78) in the placental trophoblast cells and the pathogenesis of gestational diabetes mellitus (GDM).Methods All the patients were recruited from Qingdao Municipal Hospital from May 2013 to May 2014.Among them, fifty women with GDM were assigned to the GDM group, and fifty healthy women were defined as the control group.All of them received cesarean section because of breech presentation, contracted pelvis, scarred uterus or on mother's demand.Real-time PCR was conducted to analyze the expression of GRP78 mRNA in the trophoblasts.Immunohistochemistry was performed to detect the localization of GRP78 protein in the placentasl trophoblast cells.Results (1) GRP78 mRNA expressed in the cytoplasm of trophoblasts of both the GDM group and the control group.The GRP78 mRNA levels in the GDM group and the control group were 15.6±0.4 and 6.0±0.7, respectively.The relative expression level of GRP78 mRNA in the GDM group was 2.6 times of that in the control group, with statistically significant difference (P＜0.01).(2) The expression of GRP78 protein was found in the cytoplasm of the trophoblasts of the GDM group.It showed in deep, light brown or yellow after staining, according to the expression degree.The expression of GRP78 protein was also found in the cytoplasm of the trophoblasts of the control group, but it mainly showed yellow color (38/50).The strong positive rate of GRP78 protein in the GDM group (96％, 48/50) was higher than that in the control group (22％, 11/50;P＜0.01).Conclusion The expression of GRP78 increased in the placental trophoblast cells of GDM patients.It might suggest that GRP78 had some effect on the pathogenesis of GDM.
