Objective:To evaluate the effect of Nutlin-3,a MDM2 antagonist,on the pyroptosis in SMMC-7721 cells.Methods: The expression of actived caspase-1(p20) and IL-1β was detected using Western blot analysis.Pyroptosis was investigated by a standard lactate dehydrogenase release assay(LDH).IL-1β content in the cell culture supernatant was quantified by ELISA.Results: Nutlin-3 up-regulated the expression level of actived caspase-1 and IL-1β in SMMC-7721 cells.Meanwhile,Nutlin-3 increased significantly the content of LDH and IL-1β in the cell culture supernatant(P<0.05).Conclusion: Nutlin-3 activated pro-caspase-1,promoted pyroptosis and IL-1β release in SMMC-7721 cells.

Objective To explore the association between the infection rate of Helicobacter pylori (Hp) and intake frequency of capsicum in dietary pattern. Methods A total of 914 health check-up participants were recruited from Tianjin Medical University General Hospital (male: 510,female:404). All participants were asked about the intake frequency of capsicum. Diagnostic criteria of the Hp infection included positive C13 breath test. Results The intake frequency of capsicum was ≥2 times/week, 1 time/week and <1 time/week. The infection rate of Hp was 56.08%, 49.04% and 48.29%. After adjusting for covariates, compared with the≥2 times/week, the odds ratios(95%confidence interval)of intake frequency of capsicum 1 time/week and <1 time/week: the frequency of capsicum intake ≥2 times/week was 1.00 (reference), the frequency of capsicum intake 1 time/week was 0.57(0.33-0.97) and the frequency of capsicum intake<1 time/week was 0.69(0.42-1.14) in men;the frequency of capsicum intake≥2 times/week was 1.00 (reference), the frequency of capsicum intake 1 time/week was 1.01(0.54-1.88), and the frequency of capsicum intake<1 time/week was 0.71(0.41-1.23) in women. Conclusions This study found that food intake frequency of capsicum≥2 times/week was associated with the infection rate of Hp in men. But similar relationship was not observed in women.

Objective To survey and compare the awareness and attitude of hospice care among medical staff from hospitals ranked 1, 2, and 3. And to examine the association of hospital grading with awareness and attitude of hospice care. So that this study would promote orientation for hospice care theoretically. Methods A cross-sectional questionnaire survey was performed among medical staff in Suzhou to investigate the awareness and attitude of hospice care from hospitals ranked 1, 2, and 3. Generalized linear regression model was applied to examine the association of hospital levels with awareness and attitude of hospice care. Results A total of 990 individuals were surveyed. Among them, 580 were from hospitals ranked 3, 252 were from hospitals ranked 2, and 158 were from hospitals ranked 1. The attitude to someone self′s death scored 7.2 ±2.1, 7.6 ±2.4, 7.2 ±2.1, the attitude to patients′death scored 11.0 ±2.6, 11.6 ±2.3, 11.5±2.3, there was a significant difference among the 3 levels (F=3.34, 3.69, all P<0.05). After controlling for age, education level, years of work, religion status, family type, and disease condition in family, as compared with hospitals ranked 3, the average score of the awareness of hospice care decreased 0.431 (P=0.049) and the average score of attitude to hospice care decreased 2.944 (P=0.022) in medical staff from hospitals ranked 1. As for the 7 aspects of hospice care attitude, the average score of attitude to patients′death decreased 0.634 (P=0.003), the average score of attitude to implementation of hospice care for patients and their families decreased 0.926 (P=0.046), and the average score of supporting hospice care decreased 0.664 (P=0.011) in medical staff form hospitals ranked 1 as compared with hospitals ranked 3. We failed to find a significant difference in awareness and attitude of hospice care between hospitals ranked 2 and 3 (all P>0.05). Conclusions The awareness and attitude of hospice care is poorer in medical staff from hospitals ranked 1 as compared with those from hospitals ranked 2 or 3. Our finding suggests that medical staff from hospitals ranked 1 is a target population on whom hospice care training would be performed.

Objective To explore the diagnostic value of N‐terminal Pro‐Brain Natriuretic Peptide (NT‐proBNP) in Kawasaki disease (KD) in children .Methods Ninety one children with KD were collected and 80 patients with acute upper respiratory infec‐tion were used as controls .Plasma NT‐pro BNP concentrations and other laboratory date were collected in the acute of KD .The re‐lationships between NT‐pro BNP values and different clinical and laboratory data in the acute phase were sought .Results The mean plasma NT‐pro BNP concentration in patients with KD in the acute phase was (1 042 .38 ± 528 .7)pg/mL ,significantly higher than those of control group(458 .6 ± 412 .3)pg/mL (P<0 .05) .The results of linear correlation analysis indicated that plasma NT‐pro BNP was positively correlated with CRP (r= 0 .442 ,P< 0 .05) ,and negatively correlated with Hematocrit ,Albumin and Na (r= -0 .216 ,r= -0 .204 ,r= -0 .315 ,respectively ;P<0 .05) .According to ROC analysis ,the AUC of NT‐pro BNP for detection of KD were 0 .881 ,sensitivity and specificity was 70 .1% and 84 .0% respectively for the cut‐off value of 530 pg/mL .Conclusion Our findings showed that NT‐proBNP would elevate in the acute stage of KD and was a reliable marker for the diagnosis of KD .A high level of NT‐pro BNP is associated with systemic inflammatory responses and increased vascular permeability .

Objective Neutrophil/lymphocyte ratio (NLR) is an easy-to-analyze inflammation biomarker but few studies have assessed the relationship between NLR and type 2 diabetes. In order to evaluate how NLR is related to type 2 diabetes, we designed a large scale cross?sectional study in an adult population. Method A cross?sectional study (including 49 861 men and 40 376 women) was conducted on participants recruited from the Health Management Center of Tianjin Medical University General Hospital in Tianjin, China. Measurements of neutrophil and lymphocyte counts, fasting blood glucose and other potential confounding factors were performed. Type 2 diabetes was defined according to the criteria of American Diabetes Association. Adjusted logistic regression models were used to assess relationships between NLR quintiles and type 2 diabetes. Result In the final multivariate models, the odds ratios (95% confidence interval) for T2D across NLR quintiles were 1.00 (Reference), 1.19 (1.05, 1.35), 1.33 (1.17, 1.50), 1.28 (1.13, 1.44) and 1.34 (1.19, 1.51) (P for trend<0.000 1), in men. Similar relationships were also observed in women. Conclusion This study demonstrated that NLR was related to the prevalence of type 2 diabetes in men and women, and suggesting that NLR may be an efficient and accurate prognostic biomarker for type 2 diabetes.

Objective To evaluate whether the serum uric acid (SUA) levels are related to development of prediabetes. Methods This was a 6-year cohort study, subjects were recruited from Tianjin Medical University General Hospital Health Management Center. A prospective assessment (n=30 910) was performed. Subjects without a history of prediabetes were followed up for 6 years (with a median follow-up of 2.7 person-years). All relevant variables including SUA concentrations, and fasting plasma glucose were assessed at baseline and yearly during the follow-up. Prediabetes was defined in accordance with the American Diabetes Association criteria of 2014. Multivariate-adjusted Cox proportional hazards regression models were fitted to assess relationships between the quintiles of baseline SUA and the incidence of prediabetes. Results The incidence of prediabetes was 55 per 1 000 person-years. In comparison with subjects in the lowest quintile, the odds ratios and hazard ratio (95%confidence interval) of higher quintile of SUA were 1.04 (0.93, 1.15), 1.07 (0.95, 1.19), 1.13 (1.01, 1.28) and 1.15 (1.02, 1.30) (P for trend=0.01), respectively, after adjusting for potential confounders. Conclusion SUA levels predicted an increased risk of prediabetes in adults.

Objective To explore the potential role of endogenous vascular elastase (EVE) in pathogenesis of coronary ar-tery lesions (CAL) in Kawasaki diseases (KD). Methods A total of 60 children with KD admitted from Jan. 2012 to Apr. 2013 were enrolled, and at the same time 60 febrile children with respiratory infection were enrolled as controls. The left and right coro-nary artery diameter value was measured by ultrasonic cardiogram. The levels of EVE, matrix metalloproteinases (MMP)-9 and transforming growth factor (TGF)-β1were determined by enzyme-linked immunosorbent assay and their correlations with coro-nary artery diameter were analyzed. Results The levels of EVE, MMP-9 and TGF-β1 in KD children in the acute phase were significantly higher than those in control group (P<0.01). Meanwhile, the level of EVE in KD children with coronary artery le-sion (CAL) is significantly higher than that in KD children without CAL. The results of correlation analysis indicated that the levels of EVE, MMP-9 and TGF-β1 were positively correlated with coronary artery diameters (r=0.64~0.79, P<0.01). Conclu-sions EVE plays an important role in the CAL of KD may through inducing the produce of MMP-9, TGF-β1 and finally caus-ing the formation of CAL.
