Objective:To study the correlations between ethics morality, society, psychological cognition and health and disease. Methods:A total of 356 patients were selected to analyze the influence to health and disease from six perspectives that included family ethics, social morality, life style, interpersonal relationship, mental health, and personality traits. Result:Psychosomatic diseases were occurred in 126 cases, and 220 cases of neuro-sis diseases. The disease incidences in the subjects with high cognitive level were significantly lower than those with low cognitive level (P<0. 01). The cognitive levels of family ethics, social ethics, life style, interpersonal rela-tionship, and mental health were closely related to health and disease (P<0. 05). Conclusion:The cognitive lev-els of ethics morality, society, psychology were closely associated with disease. It should be vigorously advocated that the whole society follow the ethics morality standards, to prevent diseases.

Objective To investigate the effect of autophagy on the proliferation and migration of cervi-cal cancer cells ,as well as the underlining mechanisms .Methods Rapamycin was used to induce the autophagy in HeLa cells,formation of autophagosomes was observed by staining with acridine orange under fluorescence mi -croscope.Western blot was used to detect the expression of LC 3 and PI3K/Akt/mTOR in HeLa cells.The LC3 plasmid was transfected into HeLa cells .The distribution of LC3 in cells and the expression of LC3 was identified by fluorescence microscope and Western blot ,respectively.The autophagy was inhibited with 3-methyladenine(3-MA )in HeLa cells.The cell proliferation was monitored by RTCA real -time instrument.Transwell chamber was carried out to assess cell migration .Results After 6h of rapamycin treatment ,the expression of LC3B was in-creased in HeLa cells ( P<0 .05 ) .The proliferative and migration ability were weakened compared to wild type HeLa cells(P<0.05).The same results in the presence of 3-MA.The expression of PI3K/AKT/mTOR path-way proteins were activated by rapamycin treatment and LC 3 overexpression(P<0.05).Conclusion Autophagy can suppress the proliferation and migration in cervical cancer cells ,which may relate to PI3K/Akt/mTOR path-way.

The article presents the significance of propaganda about the present medical market competition. In the article the author requests the construction of hospital propaganda system in a strategic way; points out that the establishment of the modern hospital brand is impossible without propaganda; emphasizes the necessary consciousness of the propagandists; discusses the strategy which the workers should be aware of; and analyzes the common mistakes during the propagating work.

Quality is the key not only to the competence of the hospital,but also to the "two benefits".It is the essence of the development of the hospital.Aiming at improving the management of the hospital's quality,combining with some experience before,the article discusses on the aspects as follows: change ideal and intensify consciousness,reform system and improve institution,stick to the project and put emphasis on the implement.

AIM: To investigate the role of CagA and the effect of small interference RNA (siRNA) on the release of IL-8 in H. pylori-infected gastric epithelial cells. METHODS: siRNA were transferred into CagA positive strain H. pylori NCTC 11637 by using electroporation. The CagA positive strain NCTC 11637 and the CagA negative strain NCTC 11639 were co-cultured with gastric epithelial cells and the level of IL-8 in the supernatant was measure by ELISA. RT-PCR and Western blotting were performed to detect CagA expression. RESULTS: The level of IL-8 induced by CagA positive strain NCTC 11637 was higher than the level induced by CagA negative strain NCTC 11639 ( 1 200.00 ?32.51) ng/L vs (100.00?8.58) ng/L, P0.05). Meanwhile, CagA mRNA decreased significantly in siRNAⅢgroup. The levels of CagA mRNA at 6, 12, and 24 h after electroporation were 31.3% (0.270/0.861), 57.6% (0.496/0.861), and 73.9% (0.637/0.861) of the control levels, respectively. Inhibition rate by siRNAⅢ was 68.7%. The Western blotting result in siRNA Ⅲ group showed that the level of CagA protein degraded to 30.7% (0.4/1.3) at 12 h after electroporation. In siRNA V group, the expression of CagA mRNA at 6 h is suppressed by 23.1% (P

The principal goal of opening the course of Medical Communication is to develop medical students'basic communication skills which involve three aspects:the proper use of language tools,communication and problem-solving skills in the course of general interper-sonal relationships,information communication skills between doctors and patients in the process of making a diagnosis or treatment,public communication skills on medical education and communication skills in dealing with a medical dispute or crisis between doctors and patients. This paper presents clearly the connotation of medical communication and puts forward specific programs on the organization and implementation of the course.

Double-stranded oligomeric nucleotide encoding PEP-1 peptides was synthesized, prokaryotic expression pET15b-pep-1-p27mt recombinant constructed, E. coli BL21 (DE3)pLysS transformed and induced with IPTG to highly express fusion protein PEP-1-P27mt. Fusion protein with an N-terminal His-tag could be purified by Ni2+-resin affinity chromatography and identified by SDS-PAGE and Western blotting. Cultured EC9706 cells treated with PEP-1-P27mt revealed that PEP-1-P27mt was transduced into cells after 15 min and reached maximal intracellular concentrations in 2 h. PEP-1-P27mt of 1 micromol/L final concentration could most strongly suppress the growth. It was suggested that PEP-1 can carry P27mt across membrane, which provides a new biological protocol for using cyclin dependent kinase inhibitors p27mt in suppressing the growth of tumor cells.

Objective: To further investigate the molecular mechanism of photodynamic therapy. Methods: We used cDNA microarray technique to explore the gene expression profiles of HEPG2 cells after photodynamic therapy with hematoperphyrin monomethyl ether(HMME) in HEPG2 cells. After treated with HMME for 60 min, the HEPG2 cells were irradiated with laser, and observed by microscope with H E staining. To prepare the probes, mRNA from both control and treated cells were isolated and purified, then reversely transcribed to cDNA with the incorporation of fluorecent labeled dUTP. The probes were hybridized with a cDNA microarray representing the 1 538 genes originated from human hepatocarcinoma cells. The fluorencent signals of Cy3 and Cy5 were scanned and analyzed. Results: After laser irradiation, the HEPG2 cells showed the typical feature of apoptosis. The gene expression profiles were also changed greatly. Among the 1 538 target genes, 389(2.47%) different expression genes were detected. Most of the changed genes (nearly 80%) were down regulated. They were functionally related to cell proliferation cycle, replication, metabolism and so on. Several apoptosis associated genes were detected among those up regulated genes, encoding the key proteins involved in apoptosis signal transduction, such as CCP32,AIF,Mch2. Conclusion: The HMME photodynamic therapy can initiate the apoptosis process of HEPG2 cells, which may be regulated by mitochondial pathway.[
