Objective:To survey and evaluate the situation of present clinic use of antidiabetic drugs,estimate their consuming trend and discuss the rational methods in applying antidiabetic drugs.Method:The drug purchasing data during the years of 2002 to 2006 in hospitals were compared,and statistically analyzed with Microsoft Excel.Result:Ac- counting approximately 52%-72% in total antidiabetie DDDS,sulfonylureas and bigunides were most commonly used.In- sulin and?-Glycosidase inhibitors also took more than 25%-35% share in total DDDs.Some other new drugs and tradi- tional Chinese medicine were less than 10% in total DDDs.The first line of antidiabetic drugs included mefformin,gliclas- ide,acarbose,glipizide and insulin.Conclusion:Clinical application of antidiabetic drugs was reasonable in Nanjing dis- trict.The cost of diabetes patient is the main factor which will influence the application of antidiabetic drugs normatively and continuously.

Objective To learn students' satisfaction with the general education courses, discuss the problems in comprehensive general education courses in local medical colleges , and provide the basis and reference for the medical general education courses reform. Methods Using the stratified random sampling method, self-designed questionnaire to local medical colleges of 575 different professions stu-dents. The questionnaire had the total of 54 topics whose contents were related to the basic situation aware-ness and satisfaction, the demand for general education courses, general education curriculum problems and suggestions. The survey data were analyzed using SPSS 19.0 software and the results were expressed by the relative number(rate and percentage). The differences between different majors and different grade student satisfaction were analyzed by using rank-sum test, showing statistical significance(P<0.05). Results The total satisfaction was not very high, only 219 students(38%) were satisfied with general curriculum;256 students(45%) thought it didn't matter whether to set general education courses;100 students(17%) were not satisfied. In addition, satisfaction with different grades was undifferentiated (P=0.798), but there was a statistical difference among the students of different professions(P=0.007). Conclusion The general education curriculum of medical schools should not blindly pursue being wide and full. Instead, it should be built from three aspects such as core curriculum, flexible teaching methods, teaching methods reform to enhance teaching effectiveness.

Objective:To explore the changes of NK and NKT cells and the expression levels of their activated, inhibitory receptors in the peripheral blood of patients with newly diagnosed rheumatoid arthritis ( RA), and to reveal the potiential role of NK and NKT cells played in the pathogenesis of RA.Methods:32 patients with new onset RA and 15 healthy controls were recruited.Activated and inhibitory NK and NKT cells in peripheral blood were quantified by flow cytometry.The frequency of spontaneous and stimulated IFN-γ+NK and NKT cells and CD107aγ+NK cells were examined.Finally,the potential relationship between the frequency of NK and NKT cells subsets and clinical indexes were analyzed.Results:The frequencies of NK cells in peripheral blood in RA patients were sig-nificantly lower than those in the controls ( P=0.026 ).The frequencies of NKG2D+, NKP46+activated NK cells and NKG2C+, NKG2D+,NKP46+activated NKT cells in RA patients were significantly higher than those in the controls (P=0.011,P=0.010,and P<0.001,P=0.032,P=0.001,respectively),whereas the frequencies of KIR2DL3+,KIR3DL1+and NKG2A+inhibitory NK cells and KIR2DL3+,NKG2A+inhibitory NKT cells in RA patients were significantly lower (P=0.002,P=0.002,P=0.014,and P=0.027,P=0.002,respectively).Moreover, the frequencies of stimulated IFN-γ+NK cells and IFN-γ+NKT cells, spontaneous and stimulated CD107 aγ+NK cells in RA patients were significantly higher than that in the controls ( P=0.037, P=0.004 and P=0.001, P=0.001, respectively).Furthermore,the frequencies of NK cells,NKG2Aγ+and KIR2DL3γ+inhibitory NK cells were correlated significantly with the values of DAS28 in RA patients (r=0.357,P=0.045;r=0.399,P=0.024;r=0.468,P=0.021,respectively).Conclusion:Lower frequencies of NK cells, higher frequencies of activated NK cells and activated NKT cells, lower frequencies of inhibitory NK cells and inhibitory NKT cells, and higher NK cell activity may induce the autoimmune reaction involved in the pathogenesis of RA.

Objective:To investigate the status of oral hygiene behavior of the people of 1 8 yeas old and above in Guizhou prov-ince.Methods:A total of 9 280 adults were included by multi-staged sampling from 1 2 counties in Guizhou province of China.The double entry data were processed by Epiinfo 3.5.1 and statistically analysed by SPSS 1 9.0.Results:The survey of 9 280 subjects were permanent residents from 201 0 -201 1 .1 5.9% of the total subjects experienced dental visit,those from city and contrside were 23.0%,1 2.5%;male and female were 1 4.4%,1 7.1 %,respectively.5.6% of the them experienced tooth scaling,those from city and countryside were 9.9% and 3.4%,male and female were 4.9%,6.2% respectively.The subjects with 1 time and 2 time tooth brushing a day were 58.1 % and 28.6%,respectively.6% of the subjects did not brush teeth,mainly were those over 60 years (21 .3%),those of city residents was significantly lower than countryside(7.0% vs 4.0%).Conclusion:The oral heal behavior of Guizhou residents is poor,the education of oral health should be strengthened.

Objective To explore the signal mechanism of proliferation stimulating effect of connec-tive tissue growth factor (CTGF) on hypertrophic scar (HS) derived fibroblasts. Methods <'3>H-TdR in-corporation technique was used to determine the proliferative effect of CTGF at different concentration. Western blot was applied to semi-quantitively analyze the expression of phosphorylated and total ERK1/2 protein after 0, 5, 10, 15, 30, and 60 min of CTGF stimulation, and the relative value of which was de-fined as AI to measure the activation of ERK1/2 signal pathway. PD98059 was admitted to specifically block the ERK1/2 pathway, and subsequently cell proliferation stimulated by CTGF was studied by MTT. Results CTGF could stimulate fibroblasts proliferation with a dose-dependant manner, and activa-ted the ERK1/2 signal pathway, and AI built up to 0.209±0.0201, reaching the apex at 15 min after stimulation performed. Inhibition of ERK1/2 activation by PD98059 suppressed CTGF-mediated HS fi-broblasts proliferation significantly, while OD significantly dropped. Conclusion CTGF induces a prolif-erative response in HS fibroblasts, and this action is mainly dependent on the activation of ERK1/2 signal pathway.

Objective To investigate the changes in circulatory and pulmonary monary angiotensinⅡin rats with acite lung injury(ALI)and explore the role of angiotensinⅡin ALI.Method Thirty S-D rats were randomly divided into control group(n=6)and ALI group(n=24).The ALI group was further divided into four subgroups of observation at various intervals,3,6,9 and 12 hours after administration of lipopolysaccharide (LPS)into the femoral vein(each n=6).The indices rate,blood gas analysis,wet weight/dry weight(W/D)ratio of lung lobes,and pathological changes were successively observed at 3,6,9,and 12 hours after injury.The content of angiotensinⅡin lung tissue and blood plasma were detected at above set intervals by radioimmunoassay.Data of these assays were analyzed by one-factor analysis of variance.Results Compare with the control group,pH and PaO2 of arterial blood in ALI group decreased significantly(P＜0.05)at all intervals and PaCO2 of arterial blood in ALI group decreased significanfly(P＜0.05).at all intervals and PaCO2 of arterial blood and lung W/D weight ratio increased significantly(P＜0.05),and scores of lung histopathology denoted the lung injuried(P＜0.01).After injury of lung,angiotensin Ⅱ content increased markedly in lung homogenate and blood plasma (P＜0.05).Angiotensin Ⅱ content in blood plasma reached peak value at 9 hours,and content of angiotensin Ⅱ in lung homogenates kept on increasing at allintervals of observation.Conclusions A large amount of angiotensin Ⅱ releases into lung tissue and blood plasma during ALI,suggesting systemic and pulmonary rennin-angiotensin systems are activated.

Objective Discbuss the hypertension prevalence rate in the Wuhan male taxi drivers and the dangerous factor to provide the basis for its professional publie health work. Methods The Wuhan male taxi drivers were carried on the healthy physical examination who in the Hubei province medicine medical examination center during 2005-2007 and were carried on the epidemiology statistical analysis. Results The Wuhan male taxi drivers hypertension prevalence rate is 28.28%. That is higher than the common crowd. Hypertension leaves outside the heredity factor and be closely correlated with the age of harnesses, the body weight index, and so on. Conclusions The Wuhan male taxi drivers'hypertension prevalence rate is unoptimistic. We should take the synthesis preventing and controlling measure to reduce this crowd hypertension prevalence rate.
