Objective To study the inhibitory effect of hammerhead ribozyme targeting connective tissue growth factor(CTGF) on collagen I synthesis and cell cycle progression of human hepatic stellate cell line(LX-2) cells.Methods Hammerhead ribozyme cDNA targeting CTGF mRNA plus two self-cleaving sequences were inserted into pTriEx2 vector to construct a recombinant vector pTriCTGF-Rz.LX-2 cells were transfected with either pTriEx2 or pTriCTGF-Rz and further stimulated with or without TGF-1.There were five groups in the experiment:control group,pTriEx2 group,pTriCTGF-Rz group,pTriEx2 plus TGF-?1 group,and pTrCTGF-Rz plus TGF?1 group.Semi-quantitative RT-PCR was used to detect the levels of CTGF mRNA and collagen Ⅰ mRNA.ELISA and flow cytometry were used to detect the levels of collagen Ⅰ secretion and cell cycle.Results Transfection of pTriCTGF-Rz into LX-2 cells reduced the CTGF mRNA and collagen Ⅰ mRNA levels as well as collagen Ⅰ protein level compared with pTriEx2 group(P

Oxidative stress is an important factor that can cause aging body, tissue damage and diseases.FoxO3a transcription factor is critical for the regulation of oxidative stress.Recently, there are some reports on the quite complex role of FoxO3a in regulating oxidative stress.Not only can it promote the survival of cells, but also induce cell apoptosis at some oxidative stress conditions.In this paper, the role of FoxO3a in oxidative stress, the possible signal pathway and the potential effect of target FoxO3a for oxidative stress diseases treatment are reviewed.

From the perspective of welfare culture, this paper analyzed the current status of care modes in China and explained the ethical value of multiple care mode:the development of multiple care mode was conducive to resolving the dilemmas of interpersonal relationships and strengthening community interaction;resolving the dilem-as of family relations and carrying forward the tradition of honoring and respecting the elderly;strengthening insti-tutional ethics and highlighting social concerns. Finally, this paper put forward three feasible suggestions for the development of multiple care mode:carrying forward the traditional filial piety culture and cultivating the concept of pension in the new period; developing the welfare of the combination of medical treatment and endowment and strengthening the linkage between family, community and care institutions;enhancing the quality of service of care institutions and strengthening the ethical support of caregivers.

Objective To investigate the appropriate waist circumference (WC) cutoff points for central obesity in the middle-aged and elderly Beijing residents by the metabolic syndrome definition of the International Diabetes Federation (IDF). Methods A total of 2,344Beijing residents aged ≥40 years were investigated. They answered questionnaires, received physical examinations, and underwent plasma glucose and lipid profile measurement. Those non-diabetic subjects underwent a 75g oral glucose tolerance test. All data were analyzed to calculate the appropriate WC cutoff points for central obesity reaching the diagonsis of MS. Results 1) Both in males and females, the triglyceride (TG), systolic blood pressure, diastolic blood pressure and fasting plasma glucose (FPG) increased linearly with WC, and the high density lipoprotein cholesterol (HDL-C) decreased linearly with WC (P＜0.05). 2)The prevalence of elevated TG,reduced HDL-C, elevated blood pressure, elevated FBG, or ≥ 2 of these factors increased with WC (P＜0.05). 3) Based on the receiver operating characteristic (ROC) curve analysis and Youden index, the WC values for central obesity and for detecting BMI ≥ 25 kg/m2were about 90 cm for men and 80 cm for women. 4) The odds ratio for the presence of two or more metabolic risk factors increased abruptly in men with WC ≥ 90 cm and in women with WC ≥ 80 cm. Conclusions The appropriate WC cutoff point for central obesity was determined to be 90 cm for men and 80 cm for women in the middle-aged and elderly Beijing residents by the metabolic syndrome definition of IDF.

Objective The aim of our study was to explore the relationship between prostate cancer and four serum markers,including Prostate specific antigen (PSA),Beta 2 Microglobulin (β2M),Neutrophil-to-lympochyte ratio (NLR) and Lactic dehydrogenase (LDH),and their variation rules in development of prostate cancer.Then to find one or more markers that can increase the sensitivity and specificity of diagnosis to provide reference for clinic.Methods A total of 149 prostate cancer patients,40 patients with benign prostatic hyperplasia,80 healthy subjects in our hospital were analyzed,and subsequent the T-PSA,F-PSA,β2M,LDH and NLR were measured.The correlation between these markers and prostate cancer as well as its different types and Gleason score was assessed statistically.We determined the cut-off point of the NLR and T-PSA according to the specificity and sensitivity levels derived from area under receiver operator characteristic (ROC) curve.Results The level of T-PSA was significantly higher in patients of prostate cancer and benign prostatic hyperplasia,and the level of NLR was higher only in patients of prostate cancer.Based on the area under ROC,the cut-off value of T-PSA was determined to be 4.625 ng/ml,and NLR was 2.11,and combined NLR and T-PSA can increase the specificity of diagnose.There is a statistical difference in Gleason scores in patients with different NLR of prostate cancer (P =0.030).Conclusions It could increased the specificity when combined NLR and T-PSA to diagnose prostate cancer.And NLR has positive correlation with the prognosis of patients of prostate cancer as well.

Objective To investigate the outcome and related risk factors of integrated intensive intervention in participants with impaired glucose regulation (IGR) after two years by the criteria of American Diabetes Association 2003. Methods The subjects who remained to be IGR at the end of first year following 75 g oral glucose tolerance test were randomly assigned to either a routine care control group or to an intensive integrated intervention group. The control group received general dietary and exercise advice at baseline and was followed up. In addition to dietary control and exercise advice, mefformin or acarbose were administrated in the intervention group. The latter group was also advised to take antihypertensive agents, lipid-regulating agents if necessary, as well as aspirin. Results The proportion of patients who fulfilled the assigned goals of blood glucose, blood pressure, body mass index or triglycerides was significantly higher in the intensive group than those in the control group. None in the intensive group developed overt diabetes mellitus, while 8 (9.3%) in the control group did. The proportion of patients who reverted to normal glucose tolerance (NGT) was slightly higher in the intensive group than in the control group (29.5% vs 22.1%, P>0.05). Logistic analysis showed that increase of waist circumference and systolic blood pressure was positively while the improvement of islet β-cell function was negatively correlated with the development of diabetes mellitus. Conclusions The intensive integrated intervention could significantly decrease the conversion rate of IGR to diabetes mellitus, and increase the chance of reversion to NGT. The increase of waist circumference or systolic blood pressure, the deterioration of islet β-ccll function were the influencing factors of the conversion of IGR to diabetes mellitus.

Objective:To explore the mediating effect of professional self-efficacy between professional values and willingness to work on gerontological care of nursing students in higher vocational colleges.Methods:A total of 391 nursing students from Chengdu area full-time university were investigated by general information questionnaire, gerontological nursing career motivation questionnaire, professional values scale, and professional self-efficacy scale. Pearson correlation analysis and descriptive statistical analysis were performed by SPSS 21.0. Amos 26.0 was used to establish mediating effect model and verify the mediating effect.Results:The total score of 391 nursing students' willingness to work on gerontological care was (47.05±6.93), the willingness to work on gerontological care was positively correlated with professional self-efficacy and professional values ( r = 0.826, 0.775, respectively, all P<0.01), and professional self-efficacy played a partial mediating role between professional values and willingness to work on gerontological care, accounting for 64.82% of the total effect. Conclusions:The willingness to work on gerontological care of nursing students in higher vocational colleges is at a middle level. Professional values not only directly affect the willingness to work on gerontological care, but also indirectly take function through the professional self-efficacy. Professional self-efficacy plays a mediating role in professional values and willingness to work on gerontological care of nursing students in higher vocational colleges.
