Objective To develop national norms of nursing soft skills, and provide a basis for the evaluation of the nursing soft skills for new nurses.Methods With the stratified cluster sampling, 2816 new nurses were choosed from across China, and nursing soft skills evaluation scale was used to investigate.The general descriptive statistics, reliability analysis and confirmatory factor analysis of sample data were done.Results Developed the total national norms of nursing soft skills for new nurses ( the total soft skills was 150.31 ± 15.47,interpersonal skills was 28.28 ± 3.75, organizational management was 33.74 ± 4.10, self-management was 37.50 ±4.58 ,career sentiment was 28.10 ±3.52 ,cognitive kills was 22.70 ±3.11 ) and established a T-rough and percentiles-rough score conversion tables.The level of nursing soft skills of new nurses was divided into five levels: T-score ＜ 30 was poor for the soft skill, T-score at the 30 to 39 for the somewhat less, T-score at the 40 to 59 for the general level, T-score at 60 to 69 for good,T-score ≥ 70 for the best.Conclusion These norms can be used as evaluating standards of nursing soft skills for new nurses.

Background The treatment timing and method of amblyopia rely on the plasticity of visual system.Synapsin is a family of presynaptic terminal specific protein.Its role in visual developmental plasticity is below understood.Objective To investigate the dynamic expressions of synapsin (T-synapsin),and phosphorylation of synapsin (p-synapsin Ⅰ a/b) in visual cortex of normal mice and further explore the role of synapsin in plasticity of visual system.Methods Forty-two clean neonatal C57BL/6 mice were collected.The mice were sacrificed at postnatal 7,14,21,28,35,42,60 days respectively to obtain the tissue samples of visual cortex.Expression levels of T-synapsin and p-synapsin in the visual cortex following the ageing were quantitatively detected using Western blot assay.Results The expression of synapsin in normal mice showed a dynamic increase with the ageing.The T-synapsin Ⅰ a/b/β-actin value in visual cortex was (21.32 ± 3.27) ％,(56.27 ± 10.18) ％,(77.05 ± 10.05) ％,(83.75±10.52) ％,(94.69±11.46)％,(98.75±5.86) ％ of adults mice (postnatal 60 days,P60) in the mice of postnatal 7,14,21,28,35,42 days,respectively,showing a significant difference among them (F =69.538,P ＜ 0.001).Compared with the adult mice,the T-synapsin Ⅰ a/b/β-actin value in the mice of P7,P14,P21,P28 was significantly lower (all at P＜0.05),but no significant difference was found between P35 and P60,P42 and P60 (P =0.280,0.798).The development trend of different synapsin subtypes,such as T-synapsin Ⅰ a/b,T-synapsin Ⅱ a,T-synapsin Ⅱ b and T-synapsin Ⅲ a,was not quite the same during the ageing.The expression of T-synapsin Ⅱ a and Ⅲ a increasing more slowly with development,and kept increasing until P60.Significant differences were found among various age of mice in T-synapsin Ⅱ a,Ⅱ b,Ⅲa respectively(F =42.492 55.595,39.172,all at P＜0.001).The p-synapsin Ⅰ a/b level in the visual cortex elevated with the ageing of the mice,and that peaked in P21 mice,which was (2.86±0.17) times more than that in adult mice.After that,the expression level of p-synapsin Ⅰ a/b dropped rapidly.A significant difference was found in the p-synapsin Ⅰ a/b expression among different ages of mice (F =22.620,P ＜ 0.001).Conclusions Synapsin level in visual cortex presents a developmental change which correlated with the onset and decline of the critical period.Synapsin is probably involved in the regulation of neural plasticity in visual cortex in critical period.

Background Intermittent exotropia is a type of strabismus that between latent extropia and manifest extropia.The assessment of fusional convergence/divergence is important for understanding control ability of exodeviation in children with intermittent exotropia.Objective This study was to analyze the correlations between fusional convergence/divergence and control ability of exodeviation in children with intermittent exotropia.Methods Sixty-three children with intermittent exotropia were recruited in Beijing Tongren Eye Centre from July 2013 to February 2014 under the informed consent of children and their parents.Angle of deviation was measured by wearing prism and covering method alternately.The control ability of exodeviation was evaluated and scored by the Revised Newcastle Control Score (RNCS),and fusional convergence and divergence were measured with 1 Δ-40Δ horizonal prisms and regulating targets.The correlations between the measured parameters of fusional convergence/divergence and control scores of exotropia were analyzed by Spearman rank correlation analysis.Results The mean diopter of the right and left eyes was (-1.95 ± 1.63)D and (-2.01 ± 1.73)D,respectively,and the mean deviation angle for distantly and near was (36.67 ± 15.69) Δ and (38.25 ± 14.83) Δ,respectively,without significant differences between them (diopter:t =-0.13,P＞0.05;deviation angle:t =-0.57,P＞0.05).Considerably negative correlations were found between the breakpoints of fusional convergence for distant or near and control scores of exodeviation (rs =-0.41,P=0.03;rs =-0.56,P＜0.01).No significant correlations were found between the breakpoints of fusional divergence for distantly or near and control scores of exodeviation (rs =0.05,P =0.78;rs =0.04,P ＜0.75).In addtion,there was no significant correlation between fusional recovery level and control scores (both at P ＞ 0.05).Conclusions Breakpoints of fusional convergence may be useful in grading the severity of intermittent exotropia in children,and it is probably one of the surgical indications of intermittent exotropia.

Objective To explore the relationship between genetic variation in PAF-AH V279F and coronary heart disease among Han population in Beijing.Methods A case-control study was held which enrolled 124 patients with coronary heart disease and 103 normal subjects.The genotype of PAF-AH V279F was determined with allele-specific polymerase chain reaction(AS-PCR)method. Results The highest frequency of PAF-AH V279F genetic variation was VV genotype(92.2%),the next was VF genotype(5.8%)and the lowest was FF genotype(2.0%)among the studied Han population in Beijing.In the coronary heart disease group the frequency of 279 V→F carriers was significantly higher than in the control group(19.3% vs.7.8%,P＜0.05)and F allele frequency was also higher(12.1% vs.4.9%,P＜0.01).Among the coronary heart disease group,the V279F variation frequency and the F allele frequency were significantly higher in patients with myocardial infarction than in those without myocardial infarction(27.3% vs.13.0%,17.3% vs.8.0%,both P＜0.05).In multiple logistic regression analysis,the odds ratio(OR)of V279F genetic variation for coronary heart disease was 1.919(95% CI:1.448-2.544,P=0.033).Conclusions The PAF-AH V279F genetic variation may be a novel genetic marker for high risk of coronary heart disease.

Objective To explore the correlation between-173G/C gene polymorphism of macrophage migration inhibitory factor(MIF) and Henoch-Schonlein purpura(HSP),Henoch-Schonlein purpura nephritis(HSPN) in children in Jiangxi Province.Methods One hundred and thirty-one ethnic Han children with HSP were enrolled,including 80 children with concurrent nephritis(HSPN group) and 51 children without nephritis(HSP without nephritis group).One hundred and five healthy children were used as the healthy control group.Germline DNA was extracted from peripheral blood by Promega blood genomic DNA kit.Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) was used for genotyping the-173G/C polymorphism of MIF.Genotype distribution and allele frequencies were obtained by direct counting.Statistical analysis was performed by using SPSS 11.5 software.Allele and genotype distribution were compared by using the chi-square test.The relative risk of allele was described by odds ratios(OR) and 95% confidence intervals(95%CI).Results Three genotypes(GG,GC,CC) were detected in MIF-173 G/C.GG,GC genotypes were detected in HSP without nephritis and healthy control group.GG,GC and CC genotypes were detected in HSPN group.Mutant genotype(37.5%) and C allele frequency(20.0%) in HSPN group were significantly higher than those in healthy control group(20.0% and 10.0%,respectively)(?2=6.964,7.400,Pa

Objective To observe the distribution of bone marrow mesenchymal stem cells(MSCs) and the effects on expression of apoptosis relative proteins Caspase 3 and Bcl-2 after intravenous transplanted into ischemic rat brains.Methods MSCs from SD rats were cultivated and proliferated in vitro and marked with CFSE.MSCs were then intravenously transplanted into middle cerebral artery occlusion(MCAO)models of SD rats.The rats were killed at different time points to observe the distribution of MSCs under fluorescence microscoDe as well as the effects on expression of apoptosis relative proteins Caspase 3 and Bcl-2 using immunohistochemical method.Results Density of Caspase 3 in immunohistochemically positive area in transplantion group were(2.81±0.35)%,(3.98±0.67)%,(5.58±0.92)%,(3.51±0.63)%,(1.64±0.29)%in 6,12,24,72 hours and in 7 days,respectively,and decreased significantly compared with those of control group[(3.92±0.44)%,(5.23±0.30)%,(6.89±0.57)%,(4.39±0.57)%,(2.29±0.21)%],the difference being significant(t=4.37,3.34,2.60,2.32,3.90,P＜0.05 or＜0.01).The density of Bcl-2 in immunohistochemically positive area in transplantation group were(4.70±0.16)%,(5.61±0.26)%,(3.00±0.28)%respectively in 6,12 hours and in 7 days,which had improved significantly compared with those of control group[(3.28±0.27)%,(4.54±0.59)%,(2.15±0.62)%],the difference being significant(t=8.32,3.25,2.54,P＜0.05 or＜0.01).Conclusions Bone marrow MSCs can exert protective effects on brain ischemia and reperfusion injury possibly by down-regulating Caspase 3 and up-regulating Bcl-2.

Background Argon laser peripheral iridoplasty (ALPI) is proved to be effective in lowering intraocular pressure (IOP) of patients with mild acute primary angle closure (APAC).It is unclear whether this laser treatment is equally efficient in managing patients with severe APAC.This study aimed to evaluate the IOP-lowering efficacy of ALPI and laser peripheral iridotomy (LPI) on patients with refractory APAC,who have previously responded poorly to intensive medical therapy.Methods Thirty-six patients (8 men and 28 women) were identified as medically refractory APAC,who still had ocular pain,red eye,hazy cornea,closed anterior chamber (AC) angle,and IOP of not less than 21 mmHg after two days or more of anti-glaucoma medication.All enrolled patients underwent ophthalmologic examinations including measurement of visual acuity (VA),best corrected VA (BCVA),IOP,biomicroscopy,and gonioscopy followed by ALPI immediately in the APAC eye and LPI in both eyes.Results All patients were affected unilaterally,with average age of (54.6±11.7) (range,37.0-75.0) years old.The mean IOP value of the affected eyes dropped from (31.6±7.7) (range,21.0-39.0) mmHg at enrollment to (18.4±8.7) (range,10.0-27.0) mmHg 2 hours after ALPI.At follow-up day 7,the mean IOP value maintained at (14.8±4.2) (range,9.0-21.0)mmHg,which was significantly different (P=0.000) compared with baseline.The average decrease of IOP in the APAC eyes was (16.8±7.4) (range,12.0-21.0) mmHg.At follow-up three years later,the mean IOP of the APAC eyes stabilized at (16.3±3.2) (range,9.0-20.0) mmHg with at least 180° of AC angle opened.Conclusion ALPI and LPI lower the IOP of medically refractory cases of APAC though they have responded poorly to anti-glaucoma medication.

OBJECTIVETo investigate the expression of cancerous inhibitor of protein phosphatase 2A(CIP2A) in human colorectal cancer, and to examine the association of CIP2A expression with clinicopathology and prognosis.

METHODSCIP2A expression in colorectal cancer tissue microarray of 92 cases was detected by immunohistochemistry method.

RESULTSUp-regulated CIP2A expression was closely related with TNM staging, histological type, peritoneal seeding and liver metastasis (all P<0.05), but not related with gender, age, tumor location, CEA, family history and grade of differentiation. Overall survival rates of 1-, 3-, 5-, and 10-year in high CIP2A expression group were 97.1%, 71.4%, 59.2%, and 44.4% respectively, significantly lower than 98.2%, 85.7%, 80.3%, and 74.9% in low CIP2A expression group(P=0.021). Multivariate analysis showed that CIP2A was not an independent factor associated with prognosis(P=0.099, HR=1.982, 95%CI:0.879 to 4.469).

CONCLUSIONSUp-regulated CIP2A expression is closely related to clinicopathology of colorectal cancer. CIP2A may be used as a potential predictive marker of metastasis, prognosis and therapeutic target in colorectal cancer.

OBJECTIVETo determine the effect of cysteinyl receptor agonist leukotriene D(4) (LTD(4)) and its antagonists on rat primary neurons.

METHODSIn the primarily cultured rat cortical neurons, the neuron injury was evaluated by measuring intracellular calcium, 3-(4, 5-dimethylthiazol-2yl)-2, 5-diphenyl tetrazolium bromide (MTT) reduction, and propidium iodide (PI) and Hoechst 33258 staining. The in vitro ischemic injury was induced by oxygen-glucose deprivation (OGD) for 1.5 h and reperfusion for 24 h.

RESULTLTD(4) (0.01-1 micromol/L) did not induce the elevation of intracellular calcium, neuron viability changes and neuron death. OGD-induced injury was not significantly ameliorated by the CysLT(1) receptor antagonists, pranlukast (0.2-10 micromol/L) and montelukast (0.2-10 micromol/L), as well as by the CysLT(1)/CysLT(2) receptor non-selective antagonist, BAY u9773 (0.02-1 micromol/L).

CONCLUSIONNeither agonist nor antagonists of cysteinyl receptors have the effects on the viability and ischemic-like injury in rat primary neurons.
