OBJECTIVETo investigate the role of sociopsychological factors in occupational hand injury and to provide a reference for intervention measures.

METHODSThe sociopsychological factors in 150 patients with occupational hand injury who were admitted to the Department of Hand Surgery from January to June in 2014 and 150 pair-matched normal controls were surveyed using self-made questionnaire and Life Event Scale (LES). A comparative study was carried out using t test, χ² test, and conditional logistic regression analysis.

RESULTSThe demographic characteristics, such as length of service, education level, and marital status, showed significant differences between the two groups (P<0.05) ; the LES total score and values of positive life events and negative life events also showed significant differences between the study group and control group (P<0.01) ; single-factor and multi-factor conditional logistic regression analyses showed that length of service, marital status, and negative events score were statistically significant variables (P<0.01).

CONCLUSIONSociopsychological factors play an important role in the occurrence of occupational hand injury.

Objective: To explore the clinical value of bendopnea in chronic heart failure patients with reduced ejection fraction (HFrEF). Methods: According to the existence of bendopnea or not, a total of 192 consecutive chronic heart failure patients with HFrEF admitted to our department from January 2014 to January 2016 were divided into the bendopnea group and non-bendopnea group. Subgroup analysis was performed in the subgroups with various bendopnea symptoms appearance time (0-10 s, 11-20 s and 21-30 s). The relationship between bendopnea and left ventricular ejection fraction (LVEF), 6-minute walking distance (6-MWD), NT-proBNP and NYHA classification were analyzed. Results: Bendopnea was confirmed in 74 out of 192 (38.54%) cases with HFrEF, and the average time of symptoms appearance was (8.62±2.29) s. LVEF and 6-MWD values were significantly lower in the bendopnea group than those in the non-bendopnea group (both P<0.05). The NT-proBNP level and the prevalence of patients with NYHA grade Ⅳ were significantly higher in the bendopnea group than those in the non-bendopnea group (both P<0.05). There were significant difference on LVEF, 6-MWD, NT-proBNP and patients with NYHA grade Ⅳ in bendopnea patients with various bendopnea symptoms appearance time (all P<0.05) and shorter bendopnea symptoms appearance time was related to severe symptoms and signs of chronic heart failure. Conclusion The incidence rate of bendopnea is high in patients with HFrEF, and which is related closely to the cardiac function and shorter bendopnea symptoms appearance time is related to severe symptoms and signs of chronic heart failure in HFrEF patients.
