0.05).Both HMGB1 mRNA expression and HMGB1 protein level were remarkably higher in LPS treatment group than that in control group(P0.05).CONCLUSION:RPM inhibits HMGB1 expression not only by directly suppressing STAT3 activation,but also by indirectly reducing TNF-? level.

OBJECTIVE To investigate the current situation and rationality of clinical usage of antibacterial drugs in our hospital and to find out corresponding supervision measures. METHODS According to the same method and criterion,3343 medical records of discharged patients in 14 departments were investigated retrospectively by utilizing the designed questionnaire. RESULTS The total application rate of antibacterial drugs was 60%,and the rate of preventive usage took up 41% of the total application rate,the application rate of cephalosporins was the highest,and that of quinolones was the next.For the combined usage of drugs,1 150 patients were treated with one drug,730 were treated with two drugs,and 99 were treated with more than three drugs.The treatment period of 1 086 patients was less than 7 days. CONCLUSIONS The usage of antibacterial drugs should be supervised more intensively and the training for medical personnel be strengthened to improve their knowledge of using antibacterial drugs,in order to achieve the rational usage of antibacterial drugs.

OBJECTIVE To find out relative risk factors of nosocomial infection in order to provide the evidence for taking measures to effectively control and reduce the infection rate.METHODS A retrospective survey was carried out on 19 535 cases of hospitalized patients during Jan and Dec of 2006.RESULTS In 2006,the nosocomial infection patients were 389,and the nosocomial infection rate of hospitalized patients was 1.99%;the sections with higher infection rates were respectively as follows: ICU,department of neurology,department of oncology,department of nephrology and department of pediatrics;the infected part of the body mainly occurred in respiratory tract,urinary tract,and gastrointestinal tract.In the nosocomial infection,132 strains were detected and its main pathogens were Gram-negative bacteria(52.27%).CONCLUSIONS The effective measures to control and prevent nosocomial infection rates should involve rational use of antibiotic drugs,increasing in the rate of delivering samples,shortening the period of hospitalization,decreasing in the aggressive operations and strengthening inspections of key departments.

AIM: To investigate that nicotine inhibits HMGB1 expression and release in RAW264.7 cells.METHODS: (1) RAW264.7 cells were cultured in 6 wells plate, treated with 250 μg/L LPS and 1 μmol/L or 10 μmol/L nicotine, in which the cells treated with or without 250 μg/L LPS were regarded as nicotine 1 group (N1), nicotine 2 group (N2), LPS group (LPS) and control group (C), respectively. HMGB1 protein in the cell culture media and in cell nuclear was examined by Western blotting and the cellular HMGB1 mRNA level was detected by RT-PCR. (2) Transfected with antisense RNA or sense RNA of α~7 subunit-containing nicotinic receptor (α~7nAChR), RAW264.7 cells were treated with 250 μg/L LPS and 10 μmol/L nicotine, HMGB1 protein in the culture media was also tested by Western blotting.RESULTS: (1) HMGB1 mRNA level in C group was low (1 659.20±121.05) and no significant statistical difference among groups of N1, N2 and LPS was observed (P>0.05). (2) Higher HMGB1 accumulation in the cell culture media was detected in LPS group (445.34±28.52) than that in C group. Compared to LPS group, both N1 and N2 groups distinctly attenuated HMGB1 accumulation in culture media (P<0.05). (3) Nuclear HMGB1 accumulation was lower in LPS group than that in C group, and two different nicotine concentrations markedly increased the nuclear HMGB1 accumulation compared to LPS group (P<0.05). (4) No significant difference of HMGB1 levels in culture media between antisense RNA group and LPS group was observed (P>0.05). In sense RNA group, however, HMGB1 level was observably reduced compared to antisense group (P<0.05).CONCLUSION: The present results suggest that nicotine dramatically inhibits RAW264.7 cell nuclear HMGB1 translocation and extracellular release, and this effect relies on α~7nAch receptor expression.

Reflective capacity is a very important tool of assessment for health professionals. Re-flective writing (RW) curriculum, aiming at promoting reflective capacity, is proliferating within American medical education. This paper generalizes the training process of RW capacity, its contents and evaluation tool. It discusses the meaningfulness of RW curriculum in improving doctor-patient relationship and profes-sionalism and developing academic goals. For better practice, the paper makes suggestions that we should reform our traditional medical education, develop interdisciplinary teams of teachers and evaluation tool and incorporate RW curriculum into continuing medical education.

South Africa is an ethnically and culturally diverse presidential republic country. The medical and health system consists of public and private medical care. AIDS, lower respiratory infections, neonatal diseases, and interpersonal violence and road injuries are the leading causes of adult death. South Africa has rich herbal resources, and a long history of traditional medicine, which is mainly black African traditional medicine. Until the establishment of diplomatic relations between China and South Africa in 1998, the development of TCM was significantly improved, and legislation of TCM was adopted by the government in 2000. Chinese herbal medicine has not yet formed industrial standardization, the TCM application and TCM education are insufficient. Therefore, it is suggested to accelerate the standardization of TCM, to strengthen the TCM education for professional TCM practitioners, and to form a large-scale, industrial and standardized development model. Only in these ways can TCM provide good medical services for residents in South African.
