Objective To study the effect of BMP-2 on apoptosis of human hepatoma HepG2 cells and the mechanisms.Methods Cell apoptosis was assessed by ELISA.Western blot was used to detect the expression of Bcl-2 and Fas proteins in HepG2 cells after treatment of BMP-2.Results 1～100ng/mL BMP-2 induced HepG2 cell apoptosis,and down-regulated Bcl-2 protein expression and increased Fas protein expression.Conclusions The present study suggests that BMP-2 induces HepG2 cell apoptosis may through Fas pathway.

ObjectiveTo investigate the level of caregiver burden of primary caregivers of children with autism,and explore the factors related to caregiver burden.Methods 177 caregivers of children with autism were tested with caregiver burden inventory(CBI) and childhood autism rating scale(CARS).A cross-sectional and multisite study design was used.ResultsThe scores of caregiver burden was ( 57.50 ± 14.91 ),and time-dependence burden and developmental burden were the most serious domains.Caregiver burden was affected by caregiver's age,caregiver's religious beliefs,caregiver's marital status,caregiver employment status and education degree and children's scores of CARS and degree of CARS( -0.151 ≤ r ≤0.282,P＜ 0.05 ).ConclusionThe data suggest that community care workers should pay attention to caregivers of children with autism and give them personalized health education and intervention according to the demographic characteristics of the caregivers and the severity of children disease.

Objective To investigate the quality of life (QOL) of the primary caregivers of children with autism and find the influencing factors.Methods 163 caregivers of children with autism were assessed with short form 36 health survey questionnaire(SF-36) in Chinese,and the data were analyzed by correlation.Results The QOL of the caregivers was injured in many fields.The scores of the eight dimensions of SF-36 were listed respectively as:physical functioning (PF) 84.69 ± 16.39,role limitation due to physical health (RP) 28.87 ± 22.85,bodily pain (BP) 64.72 ± 21.85,general health perception (GH) 50.06 ± 21.80,vitality (VT) 42.79 ± 23.42,social functioning (SF) 52.76 ± 25.46,role limitations due to emotional problems (RE) 32.10 ± 22.27,mental health (MH) 46.17 ± 24.43.The QOL of the primary caregiver was closely related to the caregiver's age,educational level,the family economical situation and time of caring (P ＜ 0.01),and also related to the children's age,autism procedure (P＜0.05).There was no relationship betwecn the QOL and the children's gender,time of participating in rehabilitation training,whether the only child or not,type of medical expense,the caregiver's gender,nationality,marital status,religion,relation with the children,and the family residence.Conclusions The QOL of the primary caregivers of children with autism is affected seriously,and should be intervened accordingly.

Objective To understand the current status of students' self-efficacy and sense of life meaning in medical college students, and explore the relationship between them, then give advice to improve the students' general self-efficacy and the sense of life meaning.Methods A random sampling method was used to select 386 undergraduates in a medical college from freshman to senior.The purpose in life test (PIL) revised by He Jiying (1994) and general self efficacy scale (GSES) revised by Wang Caikang (2001) were used in this research.Data were analyzed by SPSS 18.0 software, and the data were analyzed by t test, x2 test, Spearman correlation analysis.Inspection level of alpha=0.01 (double side).Results The score of GSES was (2.62 ± 0.40), and the score of PIL was (74.06 ± 11.09);t test showed that the PIL score of students with higher GSES score was higher than the PIL score of students with lower GSES score (t=5.054, P=0.000);The correlation analysis showed that GSES score was positively correlated with PIL score (r=0.283, P=0.000).Conclusion The general self-efficacy and sense of life meaning of medical college students are in the medium level, and the positive correlation exists between the two.A series of measures should be adopted to strengthen the students' general efficacy, so as to improve their sense of life.

Objective: To determine the relationship between serum omentin-1 concentration and bone mineral desity in postmenopausal women, and the adipose influence of tissue on bone mineral density (BMD). Methods: BMD values of 336 participants were measured by dual-energy-x-ray absorptiometry (DEXA) at various skeletal sites: the anteroposterior spine, femeral neck, total hip (T-hip) and total body BMD (TBMD). Body compositions including lean tissue mass (LTM) and body fat mass (FBM) were measured by DEXA. hTe plasma concentrations of adipocytokines (omentin-1, adiponectin,leptin,resistin,visfatin, andapelin) were measured by ELISA. Results: hTe overweight and obese groups had higher T-hip,femerol neck, intertrochanter BMDthan the nomal weight group. Plasma omentin-1 was negatively correlated with anteroposterior spine, femeral neck, trochanter, intertrochanter, T-hip and Ward’s BMD, after adjustment for age, BMI and fat body mass, and the correlation was not significant. Multiple stepwise regression anlysis revealed that lean body mass, menopause duration and estrogen level were the most important variables affecting the BMD and each explained 12.2%–13.7%, 6.9%–13.1%, 0.9%–1.7% of the variance. Serum adiponectin was independently associated with T-hip, lumbar spine and total BMD. Conclusion: Plasma omentin-1 is not significantly correlated with BMD in postmenopausal women. Lean body mass, menopause duration and estrogen level are the most important variables affecting the BMD. Serum adiponectin is an independent predictor of T-hip, lumbar spine and total BMD.

Objective:To reveal the status and characteristics of psychiatric nursing researches nearly five years in our country and provide some references for psychiatric nursing research development in our country in the future.Methods:The literatures related to psychiatric nursing from 2011 to 2015 were searched in China academic journal network publishing pool.Then the keywords frequency analysis and cluster analysis were conducted by using the bibliography co-occurrence analysis system (Bicomb2.0) and SPSS18.0 software and the analysis results were displayed visually.Results:In 8215 original keywords,after cleaning normatively,6643 keywords reserved finally,and there were 17 high frequency keywords among them.Through the word frequency analysis and cluster analysis,it is found that the psychiatric nursing research nearly five years in China could be classified into three major focus:psychiatric nursing safety management,psychological and rehabilitation nursing with schizophrenia patients,and promoting high quality nursing care to help improve the nursing quality.Conclusion:Psychiatric nursing research in China from 2011 to 2015 focuses on psychiatric nursing safety and quality management,and the patients with schizophrenia have been paid close attention,especially on their psychology and rehabilitation care.

Objective To valuate different effects in hepatectomy of three inflow occlusion methods including pringle maneuver, hemihepatic occlusion and portal venous occlusion. Methods 180 patients undergoing hepatectomy were randomly assigned to pringle group (group A), hemehepatic occlusion group (group B)or PV occlusion group (group C). The amount of blood lost, measurements of liver enzymes alanine aminotransferase (ALT), aspirate aminotransferase (AST), total bilirubin (TB), Serum albumin (ALB) and postoperative complication were also recorded. Results There was no operative mortality. One patient in group B changed into pringle maneuver due to the difficulties in dissecting the hemi-hepatic portal and was excluded. The amount of hemorrhage of three groups had no statistical difference. The ALT, AST, ALB and TB level of 1,3,7 days after operation had significant differences in three groups. The pringle group had a higher level ALT,AST,TB and lower ALB level than the other two groups. Conclusions All techniques of occlusion are effective and feasible for patients undergoing hepatectomies. However, compared with pringle maneuver, PV clamping and hemihepatic occlusion can relieve the liver function damage after hepatectomy.

Objective To investigate the incidence and influencing factors for sharp injuries occurred in workers in central sterile supply departments (CSSDs).Methods In October-November 2012,a multicenter cross-sectional survey was conducted,a total of 95 workers in CSSDs of 16 hospitals in Hunan Province were surveyed through questionnaires.Results A total of 89 workers (93.68%)in CSSDs sustained sharp injuries,46 (48.42%)of whom sustained 1 -5 times of sharp injuries,22(23.16%)sustained 6-10 times of sharp injuries,and 11 (11 .58%)sus-tained for at least 10 times of sharp injuries.81 workers (85.26%)sustained at least one time of sharp injuries one year before survey,52 (54.73%)of whom were injured by contaminated needles or other sharps.Logistic regression analysis revealed that higher educational background was protective factor for sharp injuries(OR 90%CI :0.05-0.87);while poor sleep quality(OR 90%CI :1 .03-17.94),frequent touching sharps(OR 90%CI :1 .11 -12.15),and irrational placing of objects by the other medical stuff (surgeons and nurses in operating rooms)(OR 90%CI :1 .23-16.98)were the risk factors for sharp injuries.Conclusion The incidence of sharp injuries among workers in CSSDs is high,which is related to personal factors and environmental factors.It is suggested to strengthen staff training to enhance their awareness of precaution.

Objective:To investigate the criterion-related validity of Menopause-Specific Quality of Life Questionnaire (MENQOL)-Chinese version and to evaluate the effect of menopausal symptoms on health related quality of life. Methods:This study was a cross-sectional survey. Three communities were randomly chosenin Changsha,and then 340 menopausal women aged 45-55 years were randomly chosen from the documented data of the 3 community health service centers. They were required to fill out 4 questionnaires: demographic questionnaire, MENQOL-Chinese version, Kupperman Index (KI) and World Health Organization Quality of Life (WHQOL)-BREF. Correlation analysis was used to measure the criterion-related validity. Results: MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) and KI total score were positively correlated (r=0.800,0.751, 0.607, 0.906 respectively); while negatively correlated with WHOQOL-BREF total score (r =-0.694,-0.851,-0.585,-0.873 respectively); MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) were signiifcantly correlated with WHOQOL-BREF subscales (physical, psychological, social relationship, environment), and the physical domain was the highest among the correlation coeffcients (r=-0.915). Conclusion:MENQOL-Chinese version shows relatively high criterion-related validity compared with KI and WHOQOL-BREF, which can be widely used to measure the quality of life of menopause women in China.

Objective To conduct a systematic review on the need and experience of patients in end of life and provide evidence-based guidance for delivery of end-of-life care in hospital and community settings. Methods Two Chinese (CBM and CNKI) and four English relevant databases (PsycINFO,MEDLINE,EMbase and CINAHL) were in-cluded to retrieve literatures on Chinese dying patients' needs and experience between inception and August 2016. The JBI Critical Appraisal Tool for qualitative studies in Australia was used to evaluate the quality of studies. The searching results were synthesized by employing Integrating Methods. Results Seventy-five findings were extracted from 9 qualified studies. The 75 findings were sequently integrated into 5 categories and finally 2 synthesized re-sults were summarized from the 5 categories. Integration result 1:under the sufferings from both physical and psy-chological aspects,dying patients require support from both family and society. Integration result 2:although death is acceptable for patients,they still hope for dignity and goals of life. Conclusion Needs of patients in end-of-life should be understood and respected. Reasonable and effective measures need to be taken to meet their needs and improve their quality of life.
