Objective To investigate the illness uncertainty state of the family members of elder patients with colostomy,explore their correlation with social support.Methods A total of 138 family members of elder patients with colostomy in two hospitals from September 2013 to November 2014 were recruited in this study.The General Information Questionnaire,Mishel Uncertainty in Illness Scale-Family Member Form (MUIS-FM) and Social Support Rating Scale (SSRS) were used to investigate the family members of elder patients with colostomy and analyse the correlation between illness uncertainty of family members and its influencing factors and social support.Results The average total score of illness uncertainty was (72.17±9.44) scores.There was significantly different of the family members of elder patients with colostomy in total uncertainty on degree of education,the relationship with patient,stoma nature and economic conditions (P＜0.05).The average total score of social support was (37.14±5.25) scores.The level of illness uncertainty was negatively associated with social support (r=-0.526,P＜0.01).Conclusions The illness uncertainty was mostly in higher levels in the family members of elder patients with colostomy and was negatively correlated with social support.Clinical practice should improve social support of family members to relieve illness uncertainty,so as to provide better services of family and promote physical and psychological rehabilitation of patients.

Objective:To compare the anti-obesity effect of green tea and black tea polyphenols and investigate their molecular mechanisms. Method:Rats were divided randomly into four groups:control group,high-fat group,high-fat diet with green tea polyphenols(GTP) supplement group,and high-fat diet with black tea polyphenols(BTP) supplement group. Body weight was determined every 2 w. After 3 months,the changes of epididymal fat tissues weight and serum lipids were observed. Expressions of those genes associated with adipocyte differentiation in epididymal fat tissues of rats were measured by real-time transcription-polymerase chain reaction,including pref-1,aP2,TNF-?,leptin,PPAR-?,C/EBP-? . Results:Both GTP and BTP prevented the increase of body weight and fat induced by high-fat diet and profoundly down-regulated those adipocyte-specific genes,including aP2,TNF-?and leptin. In addition,GTP also up-regulated the pre-adipocye marker — pref-1 and reduced the expression of transcription factor,peroxisome proliferators-activated receptor(PPAR-?) . Conclusion:Tea polyphenols could prevent obesity by reversing the adipocyte differentiation,and GTP possessed stronger inhibitory effect than BTP.

Objective: To investigate the effect of (-) epigallocatechin gallate (EGCG) and black tea polyphenols on the lipid metabolism related gene expression profile of human hepatocellular carcinoma HepG2 cells. Method: The total RNA was isolated from HepG2 cells treated with EGCG (5? mol/L), black tea polyphenols (5?g/ml) or 0.1%DMSO (control) for 8 h and was hybridized to Human 14k cDNA microarray for gene expression profile analysis. Real-time RT-PCR was conducted to confirm microarray data. Results: A total of 13 and 29 genes related to lipid metabolism showed differential change after EGCG or black tea polphenols treatment respectively, of which six genes showed consistent expression. The results of real-time PCR were consistent with the microarray data. Conclusion: The mechanism(s) by which EGCG and black tea polyphenols exerts its effects on lipid metabolism are comprehensive. The novel target identified in this study may provide new evidence for further investigation in the hypolipidemic effects of tea polyphenols.

Objective To investigate the role of macrophage?derived Act1 (nuclear factor kappa B activator 1) in the inflammatory bowel disease. Methods Genetically engineered mice carrying targeted suppression of Act1 in the mac?rophages (Anti?Act1) were used for the dextran sodium sulfate (DSS)?induced ulcerative colitis. The severity of colitis was assessed by weight loss, stool consistency, fecal blood index, colorectal length and H&E histology. The infiltration of CD45 + leukocytes and CD68 + macrophages in the inflammatory intestine was observed by immunohistochemical staining and expression levels of mRNA for inflammatory cytokines in colon tissues were analyzed by RT?qPCR. Results As com?pared with C57 mice, the anti?Act1 mice exhibited less severe acute colitis following DSS treatment, with reduced CD45 +leukocyte and CD68 + macrophage infiltrates in the colon tissue. Inflamed colons of the anti?Act1 mice expressed lower mR?NA levels of TNF?α, IL?1βand IL?6. Conclusions Targeted suppression of Act1 in the macrophages ameliorates dextran sodium sulfate?induced intestinal inflammation.

Objective To explore the correlation between epicardial adipose tissue(EAT) thickness and cardiovascular risk factors in patients with coronary artery disease.Methods According to the results of coronary angiography,84 cases of patients undergone coronary angiography were divided into the normal control group(28 patients),coronary artery disease group with single-vessel lesion (28 patients),coronary artery disease group with multi-vessels lesion(28 patients),respectively,then measured the EAT thickness and carotid intima-media thickness(IMT) by high-frequency ultrasound.A correlation analysis was carried out between the EAT and IMT and cardiovascular risk factors.Results In either coronary artery disease group with single-vessel lesion or multi-vessels lesion,the thicknesses of EAT and IMT were significantly higher than those in the normal control group(P ＜0.01),and the difference between group of single-vessel lesion and multi-vessels lesion was also statistically significant (P ＜0.01).A correlation analysis between the EAT and IMT and cardiovascular risk factors showed that there were significantly positive correlations between EAT and the IMT,age,weight,waist circumference,body mass index,low-density lipoprotein,Creactive protein (r = 0.124～0.790,P ＜0.05 or P ＜0.01),and the significantly negative correlation between EAT and high-density lipoprotein (r = - 0.203,P ＜ 0.05).Correlation between EAT and the IMT was 0.678,0.713,0.737 in the normal control group,group with single-vessel lesion,group with multivessels lesion,respectively.Conclusions There were favorable correlation between EAT and carotid IMT in cardiovascular risk factors.The more severity of coronary heart disease,the more high correlations of EAT and IMT.EAT can be a valuable index in evaluating coronary artery disease.

Objective To evaluate the value of lung ultrasound score (LUS) in the quantitative assessment of the severity of neonatal respiratory distress syndrome (NRDS) and the value of clinical diagnosis and treatment.Methods Totally 74 NRDS cases and 30 normal neonates were studied.LUS was compared with X-ray examination,clinical data,ventilator assisted ventilation and ventilator parameters.ROC curve was used to calculate sensitivity and specificity of LUS to predict the severity of NRDS and application of invasive ventilator treatment.Results The main findings of the lung ultrasound in NRDS included diffuse distribution of dense B line,disappeared A line,pleural line abnormalities,decreased pulmonary slip sign and pulmonary consolidation.LUS in patients with NRDS was significantly correlated with X ray grades,clinical grades,assisted ventilation mode grades,number of days on ventilator and ventilator parameters (all P＜0.05).LUS value to predict mild,moderate and severe NRDS were 13.0,22.5,and 29.5,respectively.The best cutoff point for LUS to predict the adoptation of invasive assisted ventilation was 22.5,which had sensitivity of 86.0 ％ and specificity of 64.5 ％.Conclusion LUS can be used to diagnose and evaluate the severity of the desease,and to guide the clinical diagnosis and treatment.

Objective To establish a mouse model of diethylnitrosamine(DEN)-induced hepatocellular carcinoma (HCC),and to explore the effects of two different diet formulas on the establishment of DEN-induced HCC model.Methods SPF C57BL/6 mice (8 males and 8 females) were injected intraperitoneally with 25 mg/kg DEN at day 14 to establish a HCC model.The mice were divided into two groups after weaning.One group was fed with the SPF class rodents cereal-based diet,another group was fed with AIN-93G formula diet.The mice were sacrificed at the age of 9 months.The livers were weighed and the growth of liver cancer was observed and recorded.Results All the mice in the cereal-based diet group developed HCC as expected.The body weight and liver mass of the mice in the AIN-93G diet group were significantly lower than that of the cereal-based diet group.The incidence of HCC,and the number and size of tumor nodules were also significantly lower in the AIN-93G diet group than that in the cereal-based diet group.Conclusions DEN-induced HCC model has been successfully established in mice fed with cereal-based diet,while mice fed with AIN93-G diet prevented the development of DEN-induced HCC,and their body weight was decreased significantly,suggesting that dietary factors play a key role in establishment of animal disease models.

Eight mouse hybridoma cell lines which stably secreted monoclonal antibodies ( McAbs ) against human prostate-specific antigen-α1-antichymotrypsin complex ( PSA-ACT ) were obtained through hybridoma technique. After purification, the immunological characters of 8 McAbs were identified and classified by epitopes analysis through indirect enzyme-linked immunosorbent assay ( ELISA) . A pair of McAbs was chosen from above 8 McAbs, based on which a highly sensitive, simple and rapid chemiluminescence enzyme immunoassay ( CLEIA) was developed for determination of PSA-ACT in human serums using the lumino-H2 O2 reaction catalyzed by horseradish peroxidase ( HRP) as the chemiluminescence system. Several experiment factors such as coating buffer, coating concentration, dilution ratio of PSA-ACT-HRP complex, incubation time, immunoreaction protocol and chemiluminescence reaction time were optimized. The results showed that the linear range of the proposed method for PSA-ACT determination was 0-40 ng/mL (R2=0. 9943), with the detection limit of 0. 53 ng/mL. The inter-assay relative standard deviations (RSDs) were 4. 6%-6. 6%, and intra-assay RSDs were 5 . 7%-8 . 0%. The recoveries of PSA-ACT at three spiked levels in serum samples were 95. 4%-104. 2%. The proposed method exhibited a cross-reactivity of 0. 6% with free-PSA. The proposed method is stable, sensitive, rapid and simple, and provides a foundation for the development of PSA-ACT CLEIA kit and shows great value in clinical auxiliary diagnosis of prostate cancer.
