Objective To investigate the relationship between self-efficacy(SE)and subjective wellbeing(SWB)of the elderly in community.Methods 212 elderly people underwent a questionnaire survey by the Memorial University of New Foundland Scale of Happiness and the General Self-efflcacy Scale.Results The level of self-efficacy of the elderly in community was(2.39±0.63),of which impact factor was the level of education and average monthly income per person.The level of SWB was(37.31±7.24),of which impact factor was the level of education and occupation.The level of SE and SWB of the elderly sas mdderately positively correhted,r=0.36,P＜0.01. Conclusions In the practice of community care services,community nurses should take SE theory as a framework and to improve SWB by a vailety of nursing measures.

Objective To evaluate the feasibilities of the potential donors in liver cell transplantation using the human fetal hepatocytes and immortalized L-02 hepatocytes by comparing their biological features. Methods Human fetal hepatocytes were isolated from aborted fetal livers (gestational ages from 14 w to 24 w) by an improved two-stage perfusion method and cultured in a conditioned medium without any growth factors.?-fetal protein (AFP) and albumin (ALB) were detected by radioimmunoassay (RIA) and cytokeratin-19 (CK-19) was identified by cellular immunochemistry study.Immortalized L-02 hepatocytes were cultured in the same condition and the characteristic proteins were detected by the same methods.Results The viability of human fetal hepatocytes was approximately 95% using the perfusion method, and the maximum survival time of the cultured hepatocytes was 3 weeks.The expression of AFP, ALB, and CK19 was detected at the same time, especially during Day 3 to Day 7 in the culture.By comparison, the proliferation ability of L-02 hepatocyte was greater, although with a lower level of ALB secretion.The expression of AFP and CK19 was not detected.Furthermore, during the long culture, L-02 hepatocytes may undergo a morphologic change and fail to express ALB.Conclusion Human fetal hepatocyte may be a practical donor for hepatocyte transplantation with its high-level protein expression and potential bi-differentiation ability.In view of the absent expression of ALB and the morphologic change in culture, although with better proliferation, L-02 hepatocyte seems not useful for hepatocyte transplantation.

Radiofrequency ablation (RFA) has been playing an important role in the treatment of hepatocellular carcinoma (HCC). It is minimally invasive, easily repeatable and potentially curative. Many centers now accept it to be the best therapeutic choice for patients with early-stage HCC when liver transplantation or surgical resection is not suitable. In this article, we reviewed the indications, techniques , and clinical results of RFA in the treatment of HCC.Suitable patient selection, good pre-treatment planning,complete ablation, and careful post-treatment follow up are important. Techniques, such as artificial pleural effusion and ascites, contrast-enhanced ultrasonography-guided RFA,laparoscopic or open surgical approaches have reduced complications and expanded the indications for RFA.

Objective To investigate effect of dexmedetomidine on postoperative analgesia pump dose and effect.Methods 50 cases of patients with abdominal surgery under general anesthesia were selected.According to the postoperative analgesic drugs were divided into control group and experimental group, 25 cases in each group were given corresponding drug treatment.After treatment, the visual analogue scale, comfort score, adverse reaction rate and dosage of analgesic drugs were detected and compared.Results Compared with the control group,the VAS score were lower(P <0.05),the BCS score were higher(P<0.05),the adverse reaction rate were lower(P<0.05),the dosage of analgesic pump were lower(P<0.05). Conclusion Dexmedetomidine can significantly reduce postoperative pain degree of patients, reduce the incidence of adverse reaction, reduce analgesic dosage of the drug pump.

Objective To explore the clinical and echocardiographic characteristics of primary malignant pericardial mesothelioma (PPM).Methods Cases of PPM with description of echocardiographic presentations from China mainland were searched from database during 1981 to 2015.Data about the clinical and echocardiographic features of the patients were collected.Results A total of 122 patients were included for analysis.It involved mainly middle-aged [(39.9 ± 14.7)years] and male patients (79,64.8％).The most common echocardiographic demonstration was pericardial effusion (74.6％) with were mostly bloody (97.7％),followed by pericardial masses (36.9％) and pericardial thickening (18.0％).The echocardiographic diagnostic accordance rate was about 26.2％.Conclusions The most common presentation of PPM on echocardiogram is massive pericardial effusion.Echocardiography is of great value in screening and assessment of PPM.The definitive diagnosis is made by histopathological examination.

SPSS 22.0 was used to conduct factor analysis.Results:The four major common factors evaluating the teaching effect of integrated curriculum were the effectiveness of teaching process, the rationality of teaching organization, the education of teaching content, and the innovation of teaching methods.Conclusion:The integrated curriculum reform of basic medicine should pay great attention to the simultaneous development of basic theory learning and practical ability training, the effective connection between theoretical teaching and experimental teaching, the educational role in comprehensive quality cultivation of students, and the flexible application of various teaching means and methods.

Objective To evaluate the accuracy of high-aensitivity C-reactive protein (hs-CRP) in the prediction of perioperative cardiovascular accidents (CVAS) in patients with diabetes mellitus. Methods Ninetyone type 2 diabetic patients undergoing elective non-cardiac surgery were divided into 3 groups according to their blood concentrations of hs-CRP: low-concentration group ＜ 1.0 mg/L ( group Ⅰ , n = 9); median-concentration group 1.0-2.9 mg/L (group Ⅱ ,n= 16) and high-concentration group 3.0-10.0 mg/L (group Ⅲ ,n =66). Risk factors for perioperative CVA were analyzed using Spearman rank correlation analysis. Various risk factors including sex, age, ASA physical status, BMI, NYHA claasification, smoking history ,preoperative ECG changes, duration,treatment and complications of diabetes mellitus, hypertension and blood lipids were correlated with perioperative CVA. The risk factors of which P values were less than 0.05 would enter the binary logistic regression analysis to stratify CVA-related risk factors. Area under the ROC curve was used to analyze the accuracy of the risk factors in prediction of perioperative CVA. Results The incidences of perioperative CVAs were 0, 31% and 35 % in Ⅰ ,Ⅱ and Ⅲ groups respectively. It was determined by Spearman rank correlation analysis that preoperative ECG,NYHA classification, age, preoperative cardiovascular color doppler ultrasound, blood hs-CRP concentration and ASA classification of physical status were important risk factors ( P ＜ 0.05 or 0.01 ). Binary logistic regression .malysis indicated that preoperative ECG, NYHA classification and age were highly related to perioperative CVA (P ＜0.05 or 0.01).The area under ROC curve of preoperative ECG, NYHA classification, age and blood hsCRP concentration was 0.855, 0.755, 0.702 and 0.605 respectively. Conclusion The accuracy of blood concentration of hs-CRP in prediction of perioperative CVA in patients with diabetes mellitus is lower than that of the preoperative ECG, NYHA classification or age.

Objective To investigate the role of muhiplex ligation-dependent probe amplification(MLPA) in identifying fetal aneuploidy of chromosomes 13,18,21,X,and Y. Methods From June 2007 to December 2008,263 samples(prenatal diagnosis group),including amniotic or umbilical cord blood from pregnant women who required prenatal diagnosis,were processed in parallel by MLPA and conventional karyotype to detect fetal aneuploidy.Another 26 samples(fetal death group).ineluding retained abortion and fetal death,were also processed bv MLPA. Results Five cases of 21-trisomy,4 eases of 18-trisomy,1 case of 13-trisomy and 3 cases of 45,X were identified among the prenatal diagnosis group by MLPA,and the results were consistent with karyotype.Two cases of 45,X and 1 case of 18-trisomy were identified among the retained abortion and fetal death group. Conclusions MLPA is a rapid,efficient,simple,reliable and economical technique in detecting most common chromosomal aneuploidies and have important clinical value.

Genetic modification of barley variety can be an efficient way to improve beer quality. The objective of this study was to understand the effect of trxS gene on hydrolases activities in transgenic and non-transgenic barley seeds. The results showed that alpha-amylase, free beta-amylase and limit dextrinase activity were increased in transgenic seeds in comparison with non-transgenic seeds. Sulfhydryl content of protein in transgenic seeds was also higher than that in non-transgenic seeds, suggesting that trxS gene could express in barley seeds, which opens a new way for breeding new barley varieties to improve beer quality.
