Objective To investigate the relationship between omentin-1 and Coronary heart disease in different glucose tolerance populations. Methods Serum omentin-1 levels were determined by ELISA in 143 subjects with normal glucose tolerance,impaired glucose tolerance with CHD, type 2 diabetes mellitus with CHD. The relationships between omentin-1 and waist- to-hip ratio, body mass index (BMI), blood Glucose, serum insulin,HOMA-IR and blood fat were also explored.Coronary artery stenosis was screnned by coronary interventional angiography and assessed by Gensini scoring system. Results Serum omentin-1 levels were all lower in T2DM and IGT subjects than those in control subjects (P<0.01). Serum omentin-1 was correlated positively with high density lipoprotein-cholesterol (P < 0.01),and inversely with body mass index,waist-hip ratio,diastolic blood pressure, triglyceride,fasting blood glucose,fasting insulin,HbA1c,[w1]and insulin resistance(HOMA-IR)(P<0.05 or P <0.01).Omentin-1 levels was negative related with Gensini coronary artery score (P < 0.01). Multiple linear regression showed body mass index,HOMA-IR,diastolic blood pressure were independently associated with omentin-1 levels (P<0.05 or P<0.01). Conclusions Serum omentin-1 levels, associated with fat,insulin sensitivity, are likely to play an important role in insulin resistance and the development of CHD in populations with different glucose tolerance.

To explore the characteristics of hematological abnormalities in patients with systemic lupus erythematosus (SLE) through retrospective analysis.A total of 445 SLE patients were recruited and divided into 5 groups of low white blood cell,immune thrombopenic purpura,anemia,pancytopenia and control without hematological abnormalities.Among them,351 (78.9％) had hematological abnormalities and 94 (21.1％) without hematological abnormities.The prevalence of anemia,leucocytopenia,thrombocytopenia and pancytopenia were 56.0％ (246/445),27.6％ (123/445),13.5％ (60/445) and 8.5％ (38/445) respectively.The incidence of renal damage in anemia group was significantly higher than that in control group (P ＜ 0.01).SLE patients with hematological abnormalities had lower complement C3 levels (P ＜ 0.05) and higher systemic lupus erythematosus disease activity index (SLEDAI) (P ＜ 0.01).Anemia is the most common findings in SLE patients with hematological abnormalities who have lower complement C3 levels and higher SLEDAI.

Objective To discuss the influence of team-based learning (TBL) on autonomous learning ability of undergraduate nursing students. Methods 160 undergraduate nursing students of Grade 2010 were randomly divided into experimental group and control group with 80 students in each group. Students in the experimental group were taught with TBL while students in the control group were taught with lecture-based learning (LBL). The score of autonomous learning ability was measured by scale of self-directed learning ability for nurses. Results Scores of autonomous learning ability in experimental group (120.33 ±16.09) was higher than that of control group (110.87 ±11.89) (P=0.000) and also higher than that of experimental group (100.35±11.15) before the implementation of TBL (P=0.000). The differences were statistically significant. Conclusion Team-based learning (TBL) can be helpful in improving the autonomous learning ability of undergraduate nursing students.

AIM: To explore the roles of heat shock protein 90 (HSP90) in the blockage of hydrogen sulfide (H2S) against chemical hypoxia-mimetic agent (cobalt chloride, CoCl_2)-induced oxidative stress injuries in H9c2 cardiac cell. METHODS: H9c2 cells were treated with CoCl_2 to set up the chemical hypoxia-induced the model of cardiomyocyte injury. Sodium hydrosulfide (NaHS, a H2S donor) was added into medium for 30 min before CoCl_2 treatment. ATP content was detected by high performance liquid chromatogram (HPLC). Mitochondrial membrane potential (MMP) was measured by rhodamine123 (Rh123) staining and photofluorography. The activity of superoxide dismutase (SOD) was observed using a SOD kit. The expression of heme oxygenase-1 (HO-1) was evaluated by Western blotting. RESULTS: CoCl_2 at concentration of 600 μmol/L significantly reduced SOD activity, ATP level and MMP, and enhanced the expression of HO-1 in H9c2 cells. Pretreatment with 400 μmol/L NaHS dramatically inhibited the cytotoxicity induced by CoCl_2, increased SOD activity, ATP level and MMP, decreased HO-1 expression. 17-allylamino-17 demethoxygeldanamycine(17AAG), an inhibitor of HSP90, obviously blocked the inhibitory effect of H2S on the CoCl_2-induced cytotoxicity, reduced the levels of ATP and MMP, increased HO-1 expression. However, no significantly influence on SOD activity was observed. CONCLUSION: HSP90 may mediate the cardioprotection of H2S via inhibiting the oxidative stress induced by chemical hypoxia.

Objective To compare the molluscicidal effects between“Luo-wei”(TDS),a plant molluscicide in 4 percent, and metaldehyde and niclosamide(MNSC)in the field. Methods A natural ecological environment with Oncomelania hupensis was selected as the test area,the test concentrations of TDS and MNSC were 2.5 g/m3 and 2 ml/m3 respectively by the immersion method;the test doses of TDS and MNSC were 3 g/m2 and 2 ml/m2 respectively by the spray method;the doses of WPN in a control group were 2 g/m3 and 2 g/m2 respectively by the two methods above-mentioned. The molluscicidal effects between TDS and MNSC were compared by using the synchronous design method and parallel comparative method. Results In the TDS group,the death rate of snails was 90.70%by immersion for 24 hours,reached to 81.40%after spraying for 7 days,and there were no significant differences among the observation time points in molluscicidal effects(P>0.05). One day after the spraying,the death rate of snails was less in the TDS group compared with that in the MSCN group(P<0.01),but the death rates of snails were similar in both groups 3 days after the spraying(P>0.05). In the MSCN group,the death rate of snails was 99.17%by immersion for 24 hours,reached to 66.07% by spraying for 1 day. In the WPS group,the death rate of snails was 97.15% by immersion for 24 hours,reached to 71.43%after spraying for 1 day,and there were no significant differences(both P>0.05). Conclusion TDS has a good molluscicidal activity and stable efficacy,and the molluscicidal effect of TDS is similar to that of MSCN in the filed, but the molluscicidal sensitivity of TDS is lower than that of MSCN.
