Objective To improve the influence on physical and mental health of nurses caused by frequent night shifts in order to stabilize the nursing care ranks and sublimate comprehensively the quality of nursing. Methods We selected night shift nurses working at clinical departments at random, divided into the experimental group and the control group.The experimental group was provided coffee and milk at the fixed period of night time, however, the control group was not supplied during the night shift.We designed questionnaire according to the Comell Medical Index (CMI), the Trait Coping Style Questionnaire (TCSQ) and the needing of the research. In addition, we determined the concentrations of adrenal eortisol and blood glucose in the experimental group and the control group. Results The experimental group compared with the control group had stronger excitability, more active enthusiasm. Coffee and milk eliminated sleepiness during work without affecting sleep after work, and increased significantly the concentrations of adrenal cortisol and blood glucose, the difference had statistical significance. Conclusions With the supply of specific nutrients to night shift nurses can interfere and eliminate anthropogenicly night shift nurses sleepiness and fatigue, reduce nursing accident rate, and improve quality of care.

Objective To investigate the application of intravascular ultrasonography in guiding the performance of interventional management for coronary true bifurcation lesions. Methods A total of 62 patients with coronary true bifurcation lesions, who were admitted to authors’ hospital during the period from April 2010 to Jan. 2014 to receive double stenting treatment, were included in this study. The patients were randomly divided into intravascular ultrasonography group (IVUS group, n=32) and coronary angiography group(CA group, n=30). The minimal lumen diameter(MLD), the minimal lumen area(MLA), the reference lumen diameter (RLD), the length of the lesion and the diameter and length of the implanted stent were determined, and the results were compared between the two groups. During the follow-up period lasting for 12 months after percutaneous coronary intervention, the incidence of in - stent thrombus, target lesion revascularization (TLR) and major adverse cardiac events were recorded. Results The MLD values of the main artery and branches in IVUS group were higher than those in CA group, but the difference was not significant (P>0.05). The MLA, RLD, the diameter and length of the implanted stent in IVUS group were significantly larger than those in CA group (P<0.05). The incidence of in-stent thrombus, TLR and major adverse cardiac events in IVUS group were lower than those in CA group (P>0.05). Conclusion Intravascular ultrasound- guided double stent implantation for coronary true bifurcation lesions can help optimize the performance of stenting and improve the long-term outcome of percutaneous coronary intervention.

In order to investigate the impairment of mitochondrial membrane phospholipid localization and DNA(3867) (mtDNA(3867)) deletion and the correlation between cardiac and skeletal muscle cells in mice with viral myocarditis, 50 BALB/c mice were divided into two groups randomly. In experimental group (n=40), the mice were intraperitoneally injected with 0.1 mL Eagle liquid with CVB3(TCID50=10(8)), while in the control group (n=10), the mice were subjected to equal volume of Eagle liquid. The impairment of mitochondrial membrane phospholipid localization and mtDNA(3867) deletion rate of cardiac and skeletal muscle were detected separately at day 3, 11 and 24 after injection. The correlation of mitochondrial membrane phospholipid localization and mtDNA(3867) deletion rate between cardiac and skeletal muscle cells cells was analyzed using Spearman method. At the day 3 after injection, in both cardiac and skeletal muscle cells, mtDNA(3867) deletion rate was significantly higher in experimental group than in control group (P<0.05), but the localization of mitochondrial membrane phospholipid showed no difference between two groups (P>0.05). At day 11 after injection, the mtDNA(3867) deletion rate of both cells in experimental group was increased to the peak level (P<0.05), and the impairment of mitochondrial membrane phospholipid localization of both cells also increased markedly in experimental group as compared with control group (P>0.05). At the day 24 after injection, the impairment of mitochondrial membrane phospholipid localization and mtDNA(3867) deletion of both cells showed a recovery tendency, but still severer than those at the day 3 after injection (P<0.05). The impairment of mitochondrial membrane phospholipid localization and mtDNA(3867) deletion were consistent and synchronistic between cardiac and skeletal muscle cells, and showed good correlations (P<0.05). The impairment of mitochondria plays an important role in the pathogenesis of viral myocarditis, and the skeletal muscle cells might act as a peripheral "window" to reflect the mitochondrial damage of cardiac myocytes.

Objective To investigate the effect of high glucose on renal tubular epithelial-mesenchymal transition,and to analyze the relationship between high glucose and transforming growth factor β1(TGF-β1)and the mechanism of renal interstitial fibrosis. Methods HKC and Smad7-overexpression HKC cells were grown in DMEM/F12 medium containing 5%~10%newborn calf serum.They were cultured for 16 h in free serum medium after 80%cells were adhered onto the surface of the flask.Afterwards,they were stimulated by high glucose(glucose concentration:25 mmol/L and 50 mmol/L).The expression of α-SMA,E-cadherin and fibronectin was detected by Western blot while the supernatant level of TGF-β1 was detected by ELISA.Cell motility and migration was evaluated using Boyden chamber motogenicity assay. Results In HKC induced by high glucose,the expression of α-SMA and fibronectin protein was highly upregulated while the expression of E-cadhefin protein was down-regulated.The expression of TGF-β1was up-regulated in a dose-dependent manner.These above-mentioned effects could be obviously inhibited by anti-TGF-β1 antibody.The protein expression of α-SMA,fibronectin and E-cadherin had no obvious change in Smad7-overexpression HKC induced by high glucose.HKC exhibited enhanced motility and invasive capacity in high glucose groups,compared to that in control group.Migrated cell counting was(12.4±3.7)and(18.6±4.4)cell/HP in 25 and 50 mmol/L glucose groups respectively. Conclusion High glucose may induce renal tubular epithelialmesenchymal transition through TGF-β1 pathway,which can be inhibited by blocking the Smad signal pathway.

Objective To investigate the relationship between high-glucose-induced fibronectin(FN) expression and up-regulation of integrin-linked kinase(ILK) in human kidney tubular epithelial cells (HKC) and kidney of CD-1 mice. Methods Cultured human kidney tubular epithelial cells and streptozotocin (STZ)-indueed diabetic model of CD-1 mice were enrolled in this study.Western blot was used to detect the expression of FN and ILK.The kinase dead ILK plasmid (pCMV-kdlLK) were transferred to HKC. Results Four weeks after injection of STZ,CD-1 mice had higher blood glucose level as compared to the control [(20.3±2.7) mmol/L vs (6.1±1.4) mmol/L,P<0.01].Meanwhile,expression of FN and ILK was significantly increased in diabetic mice as compared to the control (P<0.01).There was positive correlation between the expression of FN and ILK (r=0.899,P<0.01).High-glucose could up-regulate FN and ILK expression in cultured HKC in a time- and dose-dependent manner.Blockage of ILK activation by pCMV-kdILK abrogated high-glucose-incuced FN expression in HKC. Conclusions Highglucose can induce FN expression through up-regulating ILK expression.Blockage of ILK activation abrogates this effect.
