Objective To prepare an occupation well-being scale for nurses, and test its reliability and validity. Methods After literature review and semi-structured interviews, the item pool of the occupation well-being scale for nurses was created based on theory of structure of the subjective well-being. After group discussion, and evaluation by the specialists, a pilot scale was obtained. A total of 350 clinical nurses were selected by using stratified sampling method, and their occupation well-being were surveyed by the scale. The data were used to assess the reliability and validity of the scale. Results The occupation well-being scale for nurses had 3 dimensions, including 8 exploring factors. The values of Cronbach Alpha and the split half reliability coefficient of the total scale, endogenous exogenous satisfaction, satisfaction of nurses occupation happiness were all larger than 0.9, which meaned the internal consistency was good. In the emotion dimension, the value of Cronbach Alpha and the split half reliability coefficient were less than 0.7, which meant the internal consistency was not so good. The reliability coefficient of repeated measurement of the whole scale and each dimension were greater than 0.7, suggesting the external consistency of the scale was good. The content validity index of 3 dimensions were all larger than 0.9,and the cumulative ex-planatory variables were all larger than 55%. Conclusion The occupation well-being scale for nurses proposed in this study has good reliability and validity, and can be used to evaluate the occupation well-being of the nurses.

Objective To investigate the electrophysiological characteristics of chronic alcoholic myopathy. Methods Muscle fiber conduction velocity, peripheral nerve conduction velocity, and induced potentials in 26 patients with chronic alcoholic myopathy, 13 patients with chronic alcoholic peripheral neuropathy, 21 patients with chronic alcoholic neuromuscular damage, and 20 normal subjects were detected by electromyography and single fiber electromyography. Results Electromyography revealed myogenic changes in 9 cases in the myopathy group, neurogenic changes in 7 cases in the peripheral neuropathy group, and both kind of changes in 4 cases in the neuromuscular damage group. Compared with the normal subjects, neuromuscular jitter and fiber density increased in all patients ( P 0.05). Slowed sensory nerve conduction velocity was found in 28 patients (82.35%) with peripheral neuropathy or neuromuscular damage. Conclusion Electromyography and determination of nerve conduction velocity can be used to differentiate the alcoholic myopathy from peripheral neuropathy. The abnormal muscle fiber conduction velocity can be helpful for the confirmation of myopathy.

Objective To evaluate the effect of nursing interventions on the quality of life of patients undergoing continuous ambulatory peritoneal dialysis (CAPD).Methods Randomized controlled trials (RCTs) involving nursing interventions were collected from the databases of Cochrane,PubMed,Elsevier Science Direct,VIP,CNKI and WanFang.Data were analyzed with RevMan 5.1 software.Results 8 articles met the inclusion criteria.The results of Meta-analysis showed that there was considerable heterogeneity across the analysis,which might be resulted from length of intervention and patients of different ages according to subgroup analysis,and that gender was not the factor causing heterogeneity.In the experimental group,both physical and emotional aspects after receiving nursing interventions were significantly improved than the control group.Conclusions Nursing interventions can improve the quality of life of patients with CAPD.
