Objective To evaluate the actual displacement of a femoral neck fracture following close reduction under the C-arm X-ray perspective.Methods From June, 2006 to June, 2009, we managed 12 patients with femoral neck fracture by open reduction and internal fixation.They were 8 males and 4 females, aged from 23 to 65 (average, 42.3) years old.We tried close reduction of their fractures under the C-arm X-ray perspective before a temporary fixation.Next we performed open reduction, readjusted the fracture ends, and placed internal fixation.The actual displacement of the fracture measured after open reduction was carefully compared with the close reduction under the X-ray perspective.Results A substantial displacement was found after open reduction in 7 patients who had achieved anatomic reduction under the X-ray perspective.In the other 5 patients who presented with a slight displacement after close reduction under X-ray perspective, the actual displacements were larger than the X-ray observations but completely reduced after open reduction.The actual measurements after open reduction were significantly larger (3.21 ± 0.96 mm on average) in the anteroposterior displacement ( t = 11.540, P = 0.000), but insignificantly larger (0.58 ±0.93 mm on average) in the superior-inferior displacement ( t = 2.184, P = 0.346) than those after close reduction.Conclusions In general, anatomic reduction can not be achieved for a femoral neck fracture under the C-arm X-ray perspective.Consequently, open reduction may be better than close reduction in the treatment of femoral neck fracture in that improper reduction can block blood supply to the femoral neck and dissection of the capsula articularis coxae can improve blood supply as well as help decompression.

Sleep plays an important role in the modulation of endocrine function and energy metabolism;hormone levels are markedly different during a sleepless night compared with a night of normal sleep.Sleep deprivation may change the levels of cortisol,growth hormone(GH)and thyrotropin(TSH)at night.In addition,sleep curtailment disturbs the balance of anorexi- genic(leptin)and orexigenic(ghrelin)factors,and does harmful to glucose tolerance.

OBJECTIVE:To compare the total flavonoids content and antioxidant activity in the barks,leaves,male flowers and seeds of Eucommiae ulmoides. METHODS:UV spectrophotometry was used to determine the total flavonoids content in differ-ent parts;tests was conducted to clear 2,2′-nitrilobis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS+),1,1-diphenyl-2-trinitro-phenylhydrazine(DPPH)radicals and the reducing ability of Cu2+,using half clear/reduction concentration value(IC50)as evalua-tion indexes,and vitamin C was regarded as positive control. RESULTS:The total flavonoids content of the E. ulmoides from hight to low was as follows as leaves>male flowers>barks>seeds,except there was no significant difference in barks and seeds (P>0.05),the other parts had significant differences (P<0.05);the ability of different parts eliminating DPPH and ABTS+ free radical was as follows as leaves>male flowers>seeds>barks,except there was no significant difference in the indicators of leaves and male flowers(P>0.05),the other parts had significant differences(P<0.05);the ability of reducing Cu2+ free radical was as follows as leaves>male flowers>barks>seeds,there was significant difference in leaves and males flowers with barks and seeds (P<0.05). CONCLUSIONS:The content of total flavonoids in leaves and male flowers is high,and the antioxidant activity is strong,which has a great prospect of exploitation and utilization to make up for deficiencies in barks of E. ulmoides.

Objective: To understand the effects of remuneration incentive and their influences on job satis-faction in county public hospital. Methods: Stratified random sampling was adopted. Six county public hospitals in county level in Heilongjiang province were selected as the sample. Exploratory factor analysis was used to ana-lyze the remuneration incentives, descriptive statistical analysis and logistic regression analysis were used to ana-lyze the effects and their influences on work satisfaction. Results: remuneration incentives are divided into four dimensions that comprised a total of 16 items, which including direct material rewards, indirect material re-wards, occupational rewards and social rewards. The surgeon’s job satisfaction is higher than the physician, and is lower than the obstetrics and gynecology and pediatrics. Technician and nurses’ satisfaction is lower than the general practitioner. The medical staff who worked less than5 years has the lowest satisfaction. Authorized staff’s satisfaction is lower than off-staff. Direct material rewards and occupational rewards are related to job satisfac-tion. Conclusions:Material rewards were in low level, and non-economic incentive was insufficient. The salary incentive for highly educated talents should be strengthened.

Objective To describe the epidemiological characteristics and relative factors of adults with overweight and obesity in Liaoning province.Methods With multi-stage randomized cluster sampling,8 120 cases were selected from the 540 families in seven urban and suburb districts of Liaoning province.data of overweight and obesity history and social- economic status for residents aged 18 yrs and over were investigated by face-to-face interview,weight and height of these subjects were measured.Result the overweight rate was 33.9%,the obesity rate was 13.7%.The prevalent rates of overweight and obesity were increased with the age and it was higher in city than in rural and in female than in male(all P

Objective: To investigate the prevalence of daily smoking among residents at ages of 15 years and older in Wuhan City, so as to provide insights into tobacco control. Methods: A total of 2 700 permanent residents at ages of 15 years and older were sampled using a multistage random sampling method in three districts of Wuhan City in July, 2019. Residents' demographics, tobacco use, secondhand smoke exposure and awareness of harmful effects of tobacco were collected using the core questionnaire of the Global Adult Tobacco Survey, and the factors affecting daily smoking were identified among residents at ages of 15 years and older using a multivariable logistic regression model. Results: A total of 2 700 questionnaires were allocated, and 2 551 valid questionnaires were recovered, with an effective recovery rate of 94.48%. The respondents included 1 272 men (49.86%) and 1 279 women (50.14%), and the proportion of daily smoking was 19.84% among the respondents, with a mean daily tobacco use of 16.6 cigarettes. Multivariable logistic regression analysis identified men (OR=66.191, 95%CI: 25.344-172.873), ages of 45 to 64 years (OR=2.586, 95%CI: 1.158-5.775), farmers (OR =8.477, 95%CI: 1.126-63.786), secondhand smoke exposure at home (OR=9.395, 95%CI: 5.401-16.340), secondhand smoke exposure in workplaces (OR=1.923, 95%CI: 1.081-3.423) and no smoking at home (OR=0.459, 95%CI: 0.277-0.763) as factors affecting daily smoking among residents at ages of 15 years and older in Wuhan City. Conclusions There is a high likelihood of daily smoking among men, the middle-aged and elderly, farmers and individuals with exposure to secondhand smoke in workplaces at ages of 15 years and older in Wuhan City. Health education pertaining to tobacco control requires to be reinforced among high-risk populations, and creation of a tobacco-free home is recommended in public places and workplaces based on the complete smoking ban.

Objective To discuss nursing service and charge in order to establish standard and perfect nursing cost accounting system. Methods Nursing charge was described through analyzing the nursing technology during treatment of long-term hospitalization patients and no charge of disposable items. Results Nursing work was nearly a no-reward technological service, the proportion and the standard of nursing charge was low, the charge of nursing items was incomplete, labor cost was neglected and nursing value could not be really embodied. Conclusions Nursing managers should strengthen the nursing cost management in order to establish perfect and standard nursing cost accounting system.
