ABSTRACT
Objective To explore the effect of meta-mood ability training for improving job satisfaction of nurses.Methods A total of 120 nurses were randomized into the observation group and the control group (60 cases in each group).The observation group received meta-mood ability training,while the control group was given routine training.The meta-mood ability and job satisfaction degree were investigated.Results After the intervention,job satisfaction degree and the meta-mood ability level of the observation group nurses were improved than that of the control group.Conclusions The meta-mood ability training is effective in improvement of job satisfaction degree of nurses,as well as increase clinical service quality of nurses.
ABSTRACT
<p><b>BACKGROUND</b>Cluster of differentiation 44 (CD44) is a family of transmembrane glycoproteins. As cell surface hyaluronate receptor, it has been found to be widely expressed in a variety of cells. The aim of this study is to assess the relationship among CD44 expression, DNA content, proliferation index (PI) and apoptosis in female adenocarcinoma of the lung.</p><p><b>METHODS</b>The expression of CD44, DNA index (DI), PI and apoptotic rate were studied in 61 cases of female adenocarcinoma of the lung, paracancerous tissues and 45 cases of benign lesions by flow cytometry.</p><p><b>RESULTS</b>The percent of DNA aneuploidy was 75.41% in adenocarcinoma. The expression of CD44, DI and PI in adenocarcinoma were significantly higher than those in paracancerous and benign controls (P < 0.01), however the apoptotic rate was obviously lower in adenocarcinoma than that in paracancerous and benign controls (P < 0.01). There was a positive correlation between CD44 and DI (P < 0.01), and a negative correlation between apoptosis and DI in adenocarcinoma (P < 0.01).</p><p><b>CONCLUSIONS</b>The expression of CD44, DNA content, proliferation and apoptosis may play important regulating roles in oncogenesis, development and metastasis of female adenocarcinoma of the lung.</p>
ABSTRACT
Objective To research the role of matrix metalloproteinase-9(MMP-9), transforming growth factor ?1(TGF-?1) in viral myocarditis(VM) and their relationships with myocardial fibrosis, and to explore the forensic significance on sudden death due to viral myocarditis. MethodsSelected 30 cases of VM as experimental group,there cases were divided into definite VM group(n=18) and borderline VM group (n=12);Non-VM(n=10) were selected as control group. Collagen hyperplasia was observed by Masson staining. The expression and localization of MMP-9 and TGF-?1 in viral myocarditis were quantified by immunohistochemical method. Image analysis systems and statistical methods were used for quantitative analysis. ResultsThe amount of collagen fibre in the viral myocarditis group was more than that in the control group. The expression of MMP-9 and TGF-?1 were increased obviously. MMP-9、TGF-?1 expression were positively correlated with the collagen hyperplasis. ConclusionsThe MMP-9 and TGF-?1 may contributes to myocardial fibrosis, and may act as the assistant diagnostic indexes of sudden death due to viral myocarditis.
