Development and Validation of a Management of Workplace Violence Competence Scale for Nursing Practicum Students

Purpose@#The aim of this study was to develop a scale to measure nursing students' competence in managing violence from patients and relatives in the hospital where nursing students perform clinical practicum. @*Methods@#Literature review and Delphi expert consultation were utilized to develop the content of the management of workplace violence competence scale (MWVCS). A convenience sample of 797 nursing students responded to the questionnaire. Exploratory factor analysis of the scale was performed. Internal consistency and test–retest reliability were examined. @*Results@#The MWVCS consisted of 40 items with a five-point scale. Seven factors explained 63.2% of the total explained variance. The content validity index for the scale was .99. Cronbach's α of the scale was .96, and test–retest correlations were found to be ≥ .76. @*Conclusion@#The MWVCS is a reliable and valid scale for nursing educators to assess the level of students' competence in violence management and to evaluate the effectiveness of education to enhance their ability to manage workplace violence.

Prevalence of perimenopausal syndrome among 1594 healthy women aged 40-60 years / 中华健康管理学杂志

Objective To investigate the occurrence and influencing factors of perimenopausal syndrome (MPS) and natural menopause women age 40-60 years in Guiyang city, with the purpose of providing information for planning care for menopausal women. Methods A convenient sampling was conducted among 40-60 years old healthy women visiting the three Medical Examination Centers of affiliated hospital of Guizhou Medical University, 1594 subjects were interviewed using a self-designed questionnaire. Improved Kupperman Scale was used to evaluate the MPS. Results The percentage of MPS in the 40-60 years old women is 61.60%, of them, the proportion of mild, moderate and severe cases were 38.96%, 21.52% and 1.13% respectively. Mild and moderate account for the most cases. The top 5 symptoms of MPS were:mood agitation (60.85%), wakefulness (58.22%), muscle or joint ache (57.40%) , fatigue (57.09%) and dizziness (48.68%). The incidence of MPS was related to the following factors: age, marital status, degree of education, family monthly income, current menstrual conditions, age of first sexual life and the frequency of pregnancies and deliveries. The occurrence of MPS were associated with age, educational status,family income,current menstruation condition, age of first sexual intercourse and number of pregnancies. As age increases, the severity of MPS arise. With menstrual changes from normal to irregular and menopause, the rate and severity of MPS increased. With the frequency of pregnancies increases, the possibility of moderate and severe degree of PMS increase. The natural menopause age of healthy women in Guiyang was 49.17 ± 3.12. Conclusion The occurrence of perimenopausal syndrome was related to age,current menstruation condition and frequency of pregnancies. Care for perimenopausal period should start as early as possible.

Relationship between long non-coding RNA metastasis associated lung adenocarcinoma transcript 1 and IL-6/STAT3 signaling pathway in isoniazid-induced rats liver injury / 国际药学研究杂志

Objective To explore the link between the expression of long non-coding RNA(lncRNA)metastasis associated lung adenocarcinoma transcript 1(MALAT1)and IL-6/signal trans ducers and activators of transcription 3(STAT3)signaling pathway in isoniazid induced rats liver injury. Methods Fifty-six specific pathogen-free(SPF)SD rats were randomly divided into experimen?tal group(48 rats)and control group(8 rats),each with half females and half males. The rats in experimental group were given isonia?zid of 63 mg/(kg·d)for 3,7,10,14,21 and 28 d,with 8 rats at the same time point of each day. The rats in control group were giv?en distilled water by intragastric administration. Serum levels of ALT and AST were measured by automatic biochemical analyzer;SYBR green real-time polymerase chain reaction was used to test the expression level of lncRNA MALAT1 and IL-6/STAT3 mRNA in the liver. Results Liver tissue injury occurred after 7 days and worsened with the extention of administration time. Compared with the rats in the control group,the expression level of lncRNA MALAT1 and IL-6/STAT3 mRNA as well as ALT and AST showed a trend of increase(P<0.01). The expression of ALT,AST and lncRNA MALAT1 declined at different degrees on 28(P<0.05). LncRNA MALAT1 and IL-6/STAT3 mRNA expression levels were positively correlated(P<0.01). LncRNA MALAT1 and IL-6/STAT3 mRNA expression levels had a positive correlation with the contents of ALT and AST(P<0.01). Conclusion The expression level of lncRNA MALAT1 in isoniazid induced liver injury rat models showed an abnormal rising trend,and the positive detection time preceded that of ALT and AST. The mechanism may be related to the activation of IL-6/STAT3 signaling pathway.

The Expression of IGF2 in Mouse Embryonic Stem Cells to Differentiate into Islet-Like Cells / 天津医药

Objective To observe the effects of insulin-like growth factor-2 (IGF2) in the course of mouse embryon-ic stem cells induced to differentiate into islet-like cells. Methods Mouse ES cells were induced to differentiate into islet-like cells in vitro. The expression of islet specific markers was tested by RT-PCR and immunofluorescence assay. RT-PCR/RFLP was used to test the imprinted genes IGF2 parental expression in cells at different stages. Results Islet specific mark-ers were expressed in differentiated cells, such as insulin, glucagon and C-peptide. PCR-RFLP showed that imprinted genes IGF2 derived from embryonic stem cells were biallelic expression and loss of imprinting. Conclusion Gene imprinting sta-tus of IGF2 was changed in differentiated cells in vitro.

Expression of regulatory T cells and helper T cells in human IgA nephropathy and its significance / 中华肾脏病杂志

Objective To investigate the effects of CD4+CD25high regulatory T cells(Treg)and the imbalance of helper T lymphocyte subsets(Th1/Th2)on the immunological mechanism of IgA nephropathy(IgAN)patients. Methods The percentage of Treg and helper T cells subpopulation (Th1/Th2)in the peripheral blood of IgAN patients and healthy controls was examined by flow cytometry.The FOXP3 expression was detected through intracellular staining.The correlation of Treg or Th1/Th2 with clinical parameters of IgAN was analyzed by Spearman or Pearson rank correlation test. Results The percentages of Treg and Th2 cells were significantly higher in peripheral blood of IgAN patients compared to that of healthy controls[Treg (2.14±0.82)%vs[1.59±0.53)%,Th2(2.57±0.72)%vs(1.81±1.10)%,all P＜0.05].Th1/Th2 ratio was significantly reduced in IgAN patients(5.75±1.89 vs 12.73±9.79,P＜0.05).The percentage of circulating Treg cells was positively correlated with serunl IgA concentration(r=0.397,P＜0.05),and was negatively correlated with eGFR(r=-0.376,P＜0.05).The percentage of circulating Th2 cells was positively correlated with serum IgA(r=0.468,P＜0.05). Conclusions There is a disorder of T lymphocyte population in the peripheral blood of IgAN patients.The increased Treg and Th2 cells may play an important role in the pathogenesis of IgAN.
