		                        			Secondary brain injury is closely associated with brain edema, inflammation response and other injury factors after intracerebral hemorrhage, such as the complement system activation, excitatory amino acid toxicity, the release of vasoactive substances and free radical damage. The main mode of neuronal death during secondary brain injury after intracerebral hemorrhage are necrosis and apoptosis.

		                        			Objective To study the effect of new barrel theory in improving evaluation of hospitalized patients. Methods Eight hundred hospitalized patients from September 2012 to August 2013 were randomized equally into the control group and the observation group.The last one or two items affecting patient satisfaction from the control group were used as objectives to be improved.Causal effect analysis was done pertinent to the items and the worksheet was bettered and improved and then enforced.The two groups were compared after intervention with new barrel theory in terms of satisfaction of patients during admission and discharge. Result The satisfaction of patients in the observation group during admission and discharge was significantly better than that in the control group(P<0.05).Conclusion The new barrel theory used to detect the flaws in nursing service and improve the workflow can improve assessment from the patients so that the management quality can be enhanced.

		                        			Objective  To observe the specific humoral and cellular immune response in BALB/c mice injected with pS and p18S. Methods  pS and p18S were constructed separately by inserting HBsAg gene fragment and the fusion gene fragment of HBsAg and mouse interleukin  18(IL  18) into the reading frame of pcDNA3.1+. Mice were injected with either plasmid intramuscularly in a total dose of 300 ?g per mouse. Every serum sample was detected for anti  HBs using enzyme linked immunosorbent assay(ELISA). Furthermore, HBsAg specific cytotoxic T lymphocytes activity was measured. Results  The expression of HBsAg was demonstrated by ELISA in p815 cells transfected with pS and p18S. pS can stimulate a positive antibody response. The average level was 135 mIU/ml, with the highest level of 530 mIU/ml. p18S could elicit relatively lower antibody response which was 20 mIU/ml. HBsAg specific CTL activities were 37.1% and 34% separately in pS and p18S immunized mice. It was only 13.2% when detected in   pcDNA3.1+   immunization. Conclusion  pS is effective to stimulate a humoral and cellular response in H  2d mice. IL  18 gene can not enhance the immune response when fused with HBsAg gene. Conversely, it seems to inhibit an immune response.

		                        			To investigate the potential role of hepatitis B virus(HBV) preS1 protein in mediating HBV adhesion  to liver cell, we prepared recombinant proteins of HBV preS1 in yeast. PCR was performed to amplify the gene of HBV preS1 from the plasmid pCP10/HBV ayw subtype containing the whole fragment of HBV and the PCR product was cloned into pGEM  T vector. The gene of HBV preS1 was cut from pGEM   T vector and cloned into yeast expression plasmid pGBKT7, the pGBKT7 plamids containing preSl were transformed into yeast cell AH109. The yeast protein was isolated and analyzed by sodium dodecyl sulfate  polyacrylamide gel electrophoresis (SDS  PAGE) and Western blotting. The results showed that the presence of HBV presl proteins in yeast cells was confirmed by Western slot analysis. the molecular weight of the expressed product was about 30000 Da. The findings indicated that HBV preS1 was successfully expressed in yeast system.

		                        			The nonstructural protein 5A (NS5A) of the hepatitis C virus (HCV) has been shown to interact with a variety of cellular proteins and implicated in the regulation of cell growth, interferon resistance, and other cellular signaling pathways. Using the yeast-two hybrid method, we have isolated a clone that encodes a novel NS5A--associated binding protein: NS5ABP37. Reverse transcription polymerase chain reaction (RT-PCR) method was employed to amplify the full fragment,and the plasmid pGADT7-NS5ABP37 with the Saccharomyces cerevisiae vector pGADT7 was constructed. To prove the interaction, yeast cell Y187 transformed with pGADT7-NS5ABP37 was mated with yeast cell AH109 containing pGBKT7-NS5A to verify the interaction between the novel protein coded by the new gene NS5ABP37 and NS5A.

		                        			Objective  To investigate the regulatory effects of bombesin on the growth of human immortalized gastric epithelial cell line(GES-1), and its mechanisms. Methods  ① The expression of gastrin releasing peptide receptor(GRP-R) mRNA in GES-1 was detected. ② The expression of GRP-R protein was tested by cross-linking experiment and the location of the receptors in the cells were investigated by cytochemistry. ③GES-1 cell line was incubated with varying concentrations of bombesin with or without its antagonist and growth of the cell line was determined. ④The effect of protein kinase C (PKC) inhibitor on cell growth induced by bombesin was studied. ⑤After treated with bombesin, the intracellular IP  3 and translocation of PKC activity were measured in GES-1. ⑥Semiquantification of GRP-R mRNA in this cell line treated with bombesin was performed. Results   ①Expression of mRNA of GRP-R was demonstrated in GES-1 cells. ②The GRP-R protein was about 75?103 as revealed by cross-linking study, and the receptors were identified on the cell membranes by cytochemistry. ③Bombesin stimulated the growth of GES-1 significantly, which could be inhibited by specific antagonist of bombesin. ④Bombesin-induced growth of GES-1 was also inhibited by PKC inhibitor. ⑤Bombesin induced an increase of IP  3 generation in GES-1 as well as remarkable translocation of PKC activity from cytoplasm to the cell membranes. ⑥An increase in GRP-R mRNA was induced by treatment of cell line with bombesin. Conclusions  Bombesin stimulates the growth of this GES-1 via its receptor GRP-R and through IP  3, PKC signal pathway. The increase in expression of GRP-R mRNA in GES-1 induced by bombesin indicates that bombesin might upregulate the GRP-R in the GES-1 cells.

		                        			Objective  To explore the features, diagnosis and treatment of pulmonary infection after kidney transplantation. Methods  The clinical data of 31 pulmonary infection cases among 150 patients underwent kidney transplantation were analyzed retrospectively. Results  The 31 patients with pulmonary infection after kidney transplantation included 9 cases of simple bacterial infection, 3 cases of fungus infection, 5 cases of CMV infection, 1 case of TB, 10 cases of mixed infection, and 3 cases of infection with unclear pathogen. 27 cases of the patients(27/31,87.1%) were cured, while 4 cases died of pulmonary infection. Conclusion  Pulmonary infection is a common and severe complication after kidney transplantation. Early etiological diagnosis, the prompt treatment of antibacterium,antivirus and antifungus, adjustment of immunosuppression regime, and strengthening the support therapy would improve the curative rate.

		                        			Spermatogenesis is a complex process. Current knowledge about human spermatogenesis is mainly based on the mouse model while little is known about the initial stage of this fundamental process in humans. The establishment of the model of spermatogenesis in vitro may contribute to an overall understanding of male germ cell development, an insight into the mechanisms of infertility, and clinical management of male infertility. This review summarizes current knowledge about the generation of germ cell-like cells from induced pluripotent stem cells (iPSCs) in vitro and discusses the potential application of iPSCs in the treatment of male infertility.
