Objective:To discuss the effect of transitional care on the quality of life ( QOL) and psychology in acute myocardial infarction patients after PCI. Methods:The acute myocardial infarction patients accepted PCI in our university affiliated hospitals were selected and divided into experimental group and control group randomly. The control group received routine care during the period of hospitalization. The experimental group received transi-tional care including home visits, massed learning, telephone follow-up, and the establishment of WeChat and QQ group. The QOL, anxiety, and depression were investigated pre-intervention and six months post-interven-tion to evaluate the effect of transitional care. Results:After transitional care six months later, the QOL scores in the experimental group were significantly higher than those in the control group, SAS and SDS scores were lower in experimental group than those in the control group ( P<0 . 05 ) . Conclusions:Transitional care for acute myocar-dial infarction patients after PCI could improve their QOL, and relieve their anxiety and depression level in different degrees.

Objective To evaluate the therapeutic effect of percutaneous transhepatic biliary drainage (PTBD) with different approaches in patients with hilar cholangiocarcinoma type Ⅱ-Ⅳ.Methods The short-term clinical effect and longterm survival rate were analyzed retrospectively for a group of 97 patients with hilar cholangiocarcinoma type Ⅱ-Ⅳ receiving PTBD with different approaches,i.e.unilateral and bilateral biliary drainage,each including stent placement and drainage tube implantation.Results No significant difference was found in the decreasing of TBIL and DBIL,the survival rate and survival Curve between unilateral and bilateral biliary drainage.The median survival time was 7.5 months in unilateral and 6.7 months in bilateral biliary drainage,6.0 months in single stent and 6.5 months in single drainage tube,and 4.3 months in bilateral stents,respectively.The post operation complications mainly occurred in single drainage tube.Conclusion Single biliary drainage is able to decrease bilirubin for hilar cholangiocarcinoma type Ⅱ-Ⅳ,while stent implantation should be taken as the first choice.

OBJECTIVE: To investigate the effect of ginseng total saponins (GTS) on expression of nerve growth factor in rat with polycystic ovaries. METHODS: A total of thirty rats were randomly divided into normal control group, untreated group and GTS group. Polycystic ovaries were induced by a single intramuscular injection of 4 mg estradiol valerate (EV) in rats of the untreated group and GTS group. The rats in the GTS group were administered 50 mg/kg GTS every other day by intraperitoneal injection for 30 days after the EV injection. The expressions of NGF in the ovaries, pituitary and hippocampus were observed by method of immunohistochemistry. RESULTS: Comparison with the normal control group revealed that the expressions of NGF in ovaries, pituitary and hippocampus of rats in the untreated group were increased (P<0.05). The ovarian morphology of the GTS group was almost as normal as that of the normal control group. As compared with the untreated group, the expression of NGF in ovaries of the rats in GTS group was obviously decreased (P<0.05), while the expression of NGF in pituitary and hippocampus showed on difference. CONCLUSION: GTS can decrease the expression of NGF in ovary tissue in rats with polycystic ovaries induced by EV, which may be its mechanism in lessening the polycystic ovary.

IL-18, as a polyphonic cytokine, is important in immune response and physiologic function. We designed one pair of primers, amplified the porcine IL-18 gene fused with a C-terminal 6xHistidine tag, and then subcloned into the pFastBacDual of Baculovirus transfer vector and transformed into DH10Bac containing a shuttle vector of Bacmid. After co-transfecting the recombinant plasmid into insect cells, the 18 kDa expressed protein of porcine IL-18 was detected by SDS-PAGE; the specificity of expressed protein was confirmed by Western blotting. The purified porcine IL-18 protein induced obvious proliferation of porcine T lymphocytes in vitro, which indicated that the expression of IL-18 had high biological activity.
