Objective To investigate the effect of artesunate on the expression of heat shock protein 47(Hsp47)in pulmonary fi-brosis in rats.Methods Thirty SD male rats were randomly divided into control group,model group and artesunate intervention group (intervention group).Rats in control group were intrachacheally instilled with saline (0.4 mL),while rats in other two groups 5 mg/kg bleomycin.Rats in both control group and model group were intraperitoneal injected with 1 mL saline per day sub-sequently.And the rats in intervented group were intraperitoneal injected with 10 mg/100 g artesunate per day.The body weight of day 0,day 14 and day 28 were recorded.All the rats were sacrificed on day 28.The pulmonary coefficient and the hydroxyproline content were observed.The expression of Hsp47mRNA and CollagenⅠmRNA were evaluated by RT-PCR.The Hsp47 expression was also detected by Western Blot.The pathological changes were analyzed by hamatoxylin-eosin (HE)stain and Masson stain.Re-sults (1)The body weight of control group grew much faster than other groups (P <0.05).(2)Pulmonary coefficient:model group (12.31±1.89)mg/g>intervention group (8.54±0.67)mg/g>control group(4.81±0.38)mg/g (P <0.05).(3)Ashcroft Scores:model group(5.70±1.09 )>control group (3.08±0.56),model group(5.70± 1.09)>intervention group (4.01 ± 1.25).There was no significant difference between control group and intervention group(P >0.05).(4)Hydroxyproline content:model group (620.33±66.16)μg/g>control group(379.00±35.51)μg/g,model group (620.33±66.16)μg/g >intervention group(429.00± 36.51)μg/g (P <0.05),there was no significant difference between control group and intervention group.(5)Hsp47mRNA expres-sion:model group and intervention group > control group (P <0.05),there was no difference between the first two groups(P >0.05).CollagenⅠmRNA:model group > intervention group>control group (P <0.05).(6)Western blot showed that Hsp47 ex-pression of model group was the highest in all three groups.Conclusion These results indicate that artesunate might inhibit pulmo-nary fibrosis and depress CollagenⅠproduction,and it′s probably a result of Hsp47 down regulation.

Objective To discuss the effect of psychological and behavioral intervention on sleep quality and self efficacy in patients with type 2 diabetes mellitus complicated with sleep disorder.Methods 80 patients with type 2 diabetes mellitus complicated with sleep disorder in our hospital were divided into control group (with 40 cases) and intervention group (with 40 cases)according to the random digital table method.The control group were given routine nursing,while the intervention group were given psychological and behavioral intervention based on the control group.The changes of sleep quality and self efficacy,scores of anxiety and depression and fasting blood glucose before and after intervention were compared between the two groups.Results The differences in the scores of PSQI and GESE were not statistically significant between the control group and the intervention group before intervention (P >0.05),which were significantly improved after intervention[(8.26 ±1.32)points,(29.65 ±3.01)points;(5.62 ± 1.03)points,(34.24 ±4.15)points;t =15.386,10.502,28.087,14.751,all P <0.05],and the scores in the inter-vention group were better than those in the control group (t =9.972,5.663,both P <0.05).There were not obvious differences in the scores of SAS and SDS between the control group and the intervention group before intervention(all P >0.05),which were significantly decreased after intervention[(41.24 ±3.21)points,(42.52 ±3.01 )points;(32.36 ±2.12)points,(34.24 ±4.15)points;t =19.674,12.550,27.589,19.546,all P <0.05)],and the scores in the intervention group were significantly lower than those in the control group (t =14.599,10.215,both P <0.05).There was no obvious difference in fasting blood glucose between the two groups before intervention (P >0.05),which were significantly decreased after intervention[(8.76 ±1.06)mmol/L,(6.25 ±1.32)mmol/L,t =3.646,8.955,all P <0.05],and the level in the intervention group was significantly lower than that in the control group (t =9.377,P <0.05).Conclusion The psychological and behavioral intervention can effectively improve the
sleep quality of patients with type 2 diabetes mellitus complicated with sleep disorder,improve the self efficacy,and relieve anxiety and other negative emotions,then decrease the fasting blood glucose level,which has promotion value in the clinical nursing.

Purpose:To clone and construct an eukaryotic expressive vector of ribonuclease inhibitor (RI) gene ,as well as to observe the effects of the transfected pLNCX-ri on the growth of C6 glioma cells.Methods:A segment of RI gene of 1.4 kb was obtained by Nde I/Xho digestion and cloned into pLNCX. Transfective agent and selective antibiotic were lipofect AMINE and G418 respectively. The expression of pLNCX-ri in C6 glioma cells was detected by Western blotting. And SD rats were inoculated by the transfected C6 glioma cells.Results:An eukaryotic expressive vector of RI gene was constructed successfully. RI content was remarkably higher in the transfected cells than that of in the untransfected cells. After SD rats were inoculated by the transfected C6 glioma cells,the tumorigenic time was prolonged, the tumor weight was reduced and the density of tumor vessels was notably decreased. Conclusions:These results indicated that RI gene powerfully inhibited the growth of C6 glioma cells via decreasing tumor vessels formation.
