Background Coronary artery calcification(CAC)is common in end-stage renal disease(ESRD)patients,and the extent of CAC is closely related to cardiovascular outcomes in ESRD patients.Cartilage oligomeric matrix protein(COMP),as a component of the vascular matrix,has been found to be an inhibitor of arterial calcification in basic studies.However,there is no clinical research on the correlation between COMP and CAC in maintenance hemodialysis(MHD)patients.The aim of this study was to explore the relationship between serum COMP levels and CAC and cardiovascular events in MHD patients.Methods Serum COMP levels were compared between 54 MHD patients and 66 healthy people.MHD patients were then divided into three groups according to the tertiles of the concentration of COMP level and were followed up for major adverse cardiac events(MACEs),which were defined as a combined end point of new onset angina pectoris,nonfatal myocardial infarction,heart failure,coronary artery revascularization,hospitalization due to angina pectoris and all-cause deaths.The CAC score was calculated based on computed tomography scans.Results The serum COMP level in MHD patients was significantly higher than that in the general population[984.23(248.43-1902.61)ng/mL vs.219.01(97.26-821.92)ng/mL,P<0.01].Serum COMP levels were positively correlated with CAC(r=0.313,P=0.021)and serum parathyroid hormone in MHD patients(r=0.359,P<0.01).Linear regression suggested that after adjusting for age,fasting blood glucose(Glu)and glycosylated hemoglobin(HbAlc),CAC score was an independent predictor in the final model for COMP level(β=0.424,t=3.130,P<0.01).The receiver operating characteristic(ROC)curve showed that COMP≥994 mg/mL had 68.0%sensitivity and 72.4%specificity for the prediction of severe CAC[area under the curve(AUC):0.674,P=0.030,95%CI:0.526-0.882].After a median follow-up of 16 months(8-24 months),there was no difference in the incidence rate of MACEs between the upper,middle and lower serum COMP groups.Conclusions Our study found that MHD patien

Background:Interleukin-18(IL18)gene polymorphisms are related to many inflammatory and autoimmune diseases.However,a correlation analysis between IL18-607C/A and-137G/C gene polymorphisms and Takayasu arteritis(TA)is lacking.Methods:This study enrolled 200 patients with TA as the case group and 334 region-,age-,and sex-matched healthy subjects as the control group.We genotyped alleles and genotypes at positions-607 and-137 of the IL18 gene and analyzed the distribution frequencies.Mann-Whitney U test,t test,Chi-squared test and Hardy-Weinberg equilibrium were performed.Results:After adjusting for risk factors,the adjusted odds ratios and 95%confidence intervals at position-607C/A were 0.533,0.391 to 0.880(P=0.010);0.266,0.586 to 1.002(P=0.051);and 0.122,0.552 to 1.420(P=0.613)under the dominant,additive,and recessive models,respectively.For the-137G/C polymorphism,the adjusted odds ratios and 95%confidence intervals were 1.571,1.068 to 2.311(P=0.022);1.467,1.086 to 1.980(P=0.012);and 1.815,0.901 to 3.656(P=0.095)under the dominant,additive,and recessive models,respectively.Moreover,regardless of the model used,we found no statistical difference in distribution frequency between the active and quiescent states of TA for the-607C/A(P=0.355,0.631,and 0.705,respectively)and-137G/C polymorphisms(P=0.205,0.385,and 0.208,respectively).Conclusions:The IL18-607C/A gene polymorphism may decrease the risk of TA,and thus is a protective factor,whereas-137G/C may increase the risk of TA,and thus is a risk factor.However,neither polymorphism was related to activity(active vs.quiescent)of TA.

BACKGROUND Chronic obstructive pulmonary disease(COPD)and cardiovascular diseases are often comorbid conditions,their co-occurrence yields worse outcomes than either condition alone.This study aimed to investigate COPD impacts on the five-year prognosis of patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI).METHODS Patients with CHD who underwent PCI in 2013 were recruited,and divided into COPD group and non-COPD group.Adverse events occurring among those groups were recorded during the five-year follow-up period after PCI,including all-cause death and cardiogenic death,myocardial infarction,repeated revascularization,as well as stroke and bleeding events.Major adverse cardiac and cerebral events were a composite of all-cause death,myocardial infarction,repeated revascularization and stroke.RESULTS A total of 9843 patients were consecutively enrolled,of which 229 patients(2.3%)had COPD.Compared to non-COPD patients,COPD patients were older,along with poorer estimated glomerular filtration rate and lower left ventricular ejection fraction.Five-year follow-up results showed that incidences of all-cause death and cardiogenic death,as well as major adverse cardiac and cerebral events,for the COPD group were significantly higher than for non-COPD group(10.5%vs.3.9%,7.4%vs.2.3%,and 30.1%vs.22.6%,respectively).COPD was found under multivariate Cox regression analysis,adjusted for confounding factors,to be an independent predictor of all-cause death[odds ratio(OR)=1.76,95%CI:1.15-2.70,P=0.009]and cardiogenic death(OR=2.02,95%CI:1.21-3.39,P=0.007).CONCLUSIONS COPD is an independent predictive factor for clinical mortality,in which CHD patients with COPD are associated with worse prognosis than CHD patients with non-COPD.

Intravenous anticoagulant therapy is critical to prevent ischemic events without increasing the risk of bleeding in patients with ST-segment elevation myocardial infarction(STEMI)undergoing primary percutaneous coronary intervention(PPCI).Heparin and bivalirudin are the most commonly used adjunctive anticoagulant agents during PPCI.However,the superiority of the 2 most optimal regimens with these agents in patients undergoing PPCI remains controversial.The BivaliRudin with prolonged high-dose Infusion durinG PPCI versus Heparin Trial 4(BRIGHT-4)is a large-scale,prospective,multicenter,active-control,parallel-group,open-label,randomized trial designed to test whether bivalirudin with a post-PCI high-dose infusion is superior to heparin monotherapy in STEMI patients undergoing PPCI.A total of 6000 patients will be enrolled and randomly assigned to receive bivalirudin or heparin in a 1:1 ratio.Patients allocated to the bivalirudin group will be treated with a high-dose bivalirudin infusion(1.75 mg/(kg·h))after PCI for 2 to 4 hours.In the heparin group,the use of glycoprotein IIb/IIIa inhibitors will be reserved for the development of procedural thrombotic complications.The efficacy and safety of bivalirudin will be evaluated at 30 days,6 months,and 12 months after the randomization.The primary endpoint is a composite of all-cause death or Bleeding Academic research Consortium(BARC)types 3 to 5 bleeding at 30 days after randomization.The BRIGHT-4 study protocol has received approval from the ethics committee of General Hospital of Northern Theater Command(Shenyang,China).The procedures set out in this protocol are in accordance with the principles of the Declaration of Helsinki and Good Clinical Practice guidelines.The results will be published following the Consolidated Standards of Reporting Trials statement in a peer-reviewed scientific journal(Trial registration number:NCT03822975).

Despite complications were significantly reduced due to the popularity of percutaneous coronary intervention(PCI) in clinical trials, reperfusion injury and chronic cardiac remodeling significantly contribute to poor prognosis and rehabilitation in AMI patients. We revealed the effects of HSP47 on myocardial ischemia-reperfusion injury(IRI) and shed light on the underlying molecular mechanism.We generated adult mice with lentivirus-mediated or miRNA(mi1/133TS)-aided cardiac fibroblastselective HSP47 overexpression. Myocardial IRI was induced by 45-min occlusion of the left anterior descending(LAD) artery followed by 24 h reperfusion in mice, while ischemia-mediated cardiac remodeling was induced by four weeks of reperfusion. Also, the role of HSP47 in fibrogenesis was evaluated in cardiac fibroblasts following hypoxia-reoxygenation(HR). Extensive HSP47 was observed in murine infarcted hearts, human ischemic hearts, and cardiac fibroblasts and accelerated oxidative stress and apoptosis after myocardial IRI. Cardiac fibroblast-selective HSP47 overexpression exacerbated cardiac dysfunction caused by chronic myocardial IRI and presented deteriorative fibrosis and cell proliferation.HSP47 upregulation in cardiac fibroblasts promoted TGFβ1-Smad4 pathway activation and Smad4 deubiquitination by recruiting ubiquitin-specific peptidase 10(USP10) in fibroblasts. However, cardiac fibroblast specific USP10 deficiency abolished HSP47-mediated fibrogenesis in hearts. Moreover, blockage of HSP47 with Col003 disturbed fibrogenesis in fibroblasts following HR. Altogether, cardiac fibroblast HSP47 aggravates fibrosis post-myocardial IRI by enhancing USP10-dependent Smad4 deubiquitination,which provided a potential strategy for myocardial IRI and cardiac remodeling.

Objective To assess the test-retest reliability and criterion validity of the Simplified Chinese-character version of the International Physical Activity Questionnaire Long form （IPAC）.-L） in urban community-dwelling adults in Hanghzou, China. Methods A total of 158 eligible participants aged 25-59 years from 6 neighbourhoods in two central districts of Hangzhou completed the IPAQ-L questionnaire twice within a 7-day interval. Half of the subjects wore pedometers during the first 7 days. Test-retest reliability was examined by comparing the first （Day 1） and the second （Day 9） survey of IPAQ-L Criterion validity was assessed by comparing IPAO,-L with pedometer data. Results Modest to good test-retest reliability was found with intraclass correlation coefficients of 0.67 for total PA, 0.37 to 0.73 for specific dimensions, and 0.56 to 0.71 for different intensities of PA. Total PA measured by IPAO.-L was moderately correlated with exercise levels （partial r = 0.27, P = 0.020） and walking distance （partial r = 0.31, P = 0.007）, which were measured by a pedometer, after adjusting for gender, age, educational attainment and employment status. Conclusion Our results indicate that the IPAO.-L is a reliable and validated measure for assessing physica activity levels in this population and possibly the adult population in other mainland Chinese cities.

Our previous work found that DMH1(4-[6-(4-isopropoxyphenyl)pyrazolo [1,5-a]pyrimidin-3-yl]quinoline) was a novel autophagy inhibitor. Here, we aimed to investigate the effects of DMH1 on chemotherapeutic drug-induced autophagy as well as the efficacy of chemotherapeutic drugs in different cancer cells. We found that DMH1 inhibited tamoxifen- and cispcis-diaminedichloroplatinum(II)(CDDP)-induced autophagy responses in MCF-7 and HeLa cells, and potentiated the anti-tumor activity of tamoxifen and CDDP for both cells. DMH1 inhibited 5-fluorouracil(5-FU)-induced autophagy responses in MCF-7 and HeLa cells, but did not affect the anti-tumor activity of 5-FU for these two cell lines. DMH1 itself did not induce cell death in MCF-7 and HeLa cells, but inhibited the proliferation of these cells. In conclusion, DMH1 inhibits chemotherapeutic drug-induced autophagy response and the enhancement of efficacy of chemotherapeutic drugs by DMH1 is dependent on the cell sensitivity to drugs.
