Objective To explore the application of reading education in cultivating nursing students' humanities in vocational college.Methods Nursing students were selected at random and divided into two groups,35 students in the experimental group and 50 in the control group.The students in the experimental group were given the 2-year related instruction through reading activities in the light of the principle enhance general humanities foundation in the first grade and strengthen humanistic features in the second grade.Nursing skill assessment and questionnaire oriented to humanities were used to test the educational effect.Results The result of nursing skill assessment in the experimental group was significantly better than that of the control group.The score of humanities' moral,law,culture and aesthetic dimension and the total score of the experimental group were significantly better than those of the control group.Conclusions Well targeted reading is effective in the cultivation of nursing students' humanities.Meanwhile reading education can serve as an important and beneficial way to improve the cultivation mode of vocational college's nursing humanities.

ObjectiveTo explore the diagnosis and prognosis value of clinical pneumonic infection score (CPIS) in patients with stroke-associated pneumonia (SAP).MethodsOne hundred and fifty stroke patients were evaluated and analyzed by CPIS.SAP was regarded as gold standard,and sensitivity,specificity,diagnose accordance rate,positive predictive value and negative predictive value were calculated.Results Thirty-nine patients had SAP and 111 patients did not have SAP by CPIS,and the incidence of SAP was 22.0％ (33/150).CPIS diagnostic sensitivity was 84.8％ (28/33),specificity was 90.6％ ( 106/117 ),positive predictive value was 71.8％ (28/39),negative predictive value was 95.5％ (106/111),and diagnose accordance rate was 89.3％(134/150).The patients of SAP were divided into good prognosis (28 cases) and bad prognosis (5 cases),and the CPIS was significantly lower in patients of good prognosis 7 days after SAP than that in patients of bad prognosis[(4.21 ± 2.23) scores vs. (6.05 ±2.32) scores,P ＜0.05].ConclusionsNot only CPIS has higher diagnosis rate in SAP incidence,but also has good judgment to prognosis.It is worthy of clinical application.

Objective To observe the effect of rosuvastatin calcium on lipid,vascular endothelial growth factor (VEGF),nitric oxide (NO),tumor necrosis factor (TNF)-α and interleukin (IL)-1 in hyperlipidemia patients.Methods One hundred and twenty-seven hyperlipidemia patients were randomly divided into two groups.Patients in the study group included 72 patients which were given rosuvastatin calcium 10 mg and enteric-coated aspirin 100 mg,orally,once a day for 8 weeks.The control group included 55 patients which were only given enteric-coated aspirin 100 mg,orally,once a day for 8 weeks.The change of lipid,VEGF,NO,TNF-α and IL-1 was observed before and after treatment.Results Before treatment,the level of total cholesterol(TC),triglyceride (TG),low density lipoprotein-cholesterol (LDL-C),high density lipoprotein-cholesterol (HDL-C),VEGF,NO,TNF-α and IL-1 in two groups had no significant difference (P ＞ 0.05).After treatment,the level of TC,TG,LDL-C,TNF-α and IL-1 in study group were significantly lower than those in control group [(4.410 ± 0.688) mmol/L vs.(6.491 ± 0.744) mmol/L,(1.762 ± 0.834) mmol/L vs.(2.632 ± 0.792) mmol/L,(2.256 ± 0.347) mmol/L vs.(4.544 ± 0.493) mmol/L,(41.14 ± 5.41) ng/L vs.(71.34 ± 6.76) ng/L,(0.22 ± 0.18) μ g/L vs.(0.42 ± 0.23) μ g/L] (P ＜ 0.05).The level of HDL-C,VEGF and NO in study group were significantly higer than those in control group [(1.807 ± 0.730) mmol/L vs.(1.432 ± 0.514) mmol/L,(564.86 ± 120.02) ng/L vs.(451.23 ± 100.72) ng/L,(42.39 ± 6.71) μ mol/L vs.(33.65 ± 6.24) μ mol/L](P＜ 0.05).No adverse reaction occurred in two groups.Conclusions Rosuvastatin calcium can obviously decrease the level of lipid,elevate the expression of VEGF and NO,and reduce the expression of TNF-α and IL-1.Rosuvastatin calcium can improve vascular endothelial function obviously in hyperlipidemia patients.

Objective To investigate the effect of radial artery calcification (RAC) on survival of arteriovenous fistula (AVF) and the patients in end?stage renal disease. Methods Adult ESRD patients undergoing AVF surgery between January 2013 and January 2016 at the Eighth Affiliated Hospital of Sun Yat?sen University were enrolled in this study. The clinical and biochemical data were collected. Segment of radial artery were obtained from the operation of AVF. RAC at the site of anastomotic were observed by alizarin red S and hematoxylin and eosin staining. According to RAC, the patients were divided into calcification group and non?calcification group. Kaplan?Meier analysis was performed to analyze the survival rates of the two groups, and Cox proportional hazards regression——model was used to estimate the risk factors of AVF dysfunction and all?cause mortality in ESRD patients. Results Among 180 cases of ESRD patients, 38 cases (21.1％) were developed RAC at the site of anastomotic in different degrees. Compared with the non?calcification groups, the calcification groups had a longer dialysis vintage, a higher proportion of diabetes and higher level of HbAlc (all P﹤0.05). Binary logistic regression analysis showed that dialysis vintage>5 years and diabetics were two independent risk factors of RAC at the site of anastomotic. Kaplan?Meier survival analysis demonstrated that there were no statistical differences between two groups in AVF survival (χ2=0.009, P=0.926). Calcification group had higher all?cause mortality than non?calcification groups (χ2=9.809, P=0.002). Multivariate Cox regression analysis demonstrated that homocysteine was independent risk factor for AVF dysfunction (HR=1.027, 95％CI: 1.003-1.051, P=0.027). Age was independent risk factor for all?cause mortality (HR=1.078, 95％CI: 1.035-1.122, P=0.000). Conclusions Dialysis vintage>5 years and diabetes were two independent risk factors of RAC at the site of anastomotic in ESRD patients. RAC at the site of anastomotic had no effect on AVF survival, but increased all?cause mortality.

OBJECTIVE: To investigate the effect of curcumin on the invasion and migration of human glioma cells and explore the molecular mechanisms. METHODS: MTT assay was used for screening the optimal curcumin concentrations. The effects of curcumin on the invasion and metastasis of human glioma cell lines U251 and LN229 were tested using Transwell assay, Boyden assay and wound-healing assays. The expression of the related proteins and their interactions were determined using Western blotting and coimmunoprecipitation assay. RESULTS: Curcumin at the concentration of 20 μmol/L for 48 h was used as the optimal condition for subsequent cell treatment. In the two glioma cell lines, curcumin significantly suppressed the invasion and migration of the cells ( < 0.05) and lowered the expressions of hepatoma-derived growth factor (HDGF), Ncadherin, vimentin, Snail and Slug, but increased the expression of E-cadherin. Interference of HDGF in curcumin-treated glioma cells synergistically inhibited the epithelial-mesenchymal transition (EMT) signals, while overexpression of HDGF significantly reversed the inhibitory effect of curcumin on EMT; curcumin treatment could significantly reduce the binding of HDGF to β-catenin. CONCLUSIONS Curcumin suppresses EMT signal by reducing HDGF/β-catenin complex and thereby lowers the migration and invasion abilities of human glioma cells .
