Objective： To investigate the relationship between serum resistin level and acute coronary syndrome （ACS） or stable angina pectoris （SAP）. Methods： Sixty-five patients, with coronary artery disease, were enrolled and divided into three subgroups： acute myocardial infarction （AMI）, unstable angina pectoris （UAP） and SAP, and 26 healthy people were recruited as controls in the cross-sectional study. Serum resistin levels were determined by ELISA （enzyme-linked immunosorbent assay）, and WBC （white blood cell count）, hsCRP （high sensitive C-reaction protein）, CKmax （maximum of creatinkinase）, CK-MBmax （maximum of isozyme of creatinkinase） and cTnImax （maximum of troponin） were measured by standard laboratory methods. Results： The serum resistin levels were 4 folds higher in AMI patients, 2.43 folds in UAP patients and I. 12 folds in SAP patients than in the healthy controls （P〈0.05）. The resistin levels were also significantly different between AMI [（8.16±0.79） ng/ml], UAP [（5.59±0.75） ng/ml] and SAP [（3.45±0.56） ng/ml] groups （P〈0.01）; WBC, hsCRP, CK CK-MBmax and cTnlmax were significantly increased in AMI patients over UAP and SAP patients. Spearman analysis showed that serum resistin levels were positively correlated with WBC （r=0.412, P=0.046）, hsCRP （r=0.427,p=0.037）, CK CK-MBmax and cTnImax （r=0.731, 0.678, 0.656; P〈0.01）. Conclusion： Serum resistin levels increased with inflammatory factors and myocardial impairment. The results suggest that human resistin might play an important role in the pathogenesis of atherosclerosis and AMI as an inflammatory factor.

Background and Aims: Spontaneous bacterial peritonitis(SBP) is one of the leading causes of death in patients withliver cirrhosis. We aimed to establish a prognostic model toevaluate the 1-year survival of cirrhosis patients after thefirst episode of SBP. Methods: A prognostic model was developedbased on a retrospective derivation cohort of 309cirrhosis patients with first-ever SBP and was validated in aseparate validation cohort of 141 patients. We used Uno’sconcordance, calibration curve, and decision curve (DCA)analysis to evaluate the discrimination, calibration, and clinicalnet benefit of the model. Results: A total of 59 (19.1%)patients in the derivation cohort and 42 (29.8%) patientsin the validation cohort died over the course of 1 year. Aprognostic model in nomogram form was developed withpredictors including age [hazard ratio (HR): 1.25;95% confidenceinterval (CI): 0.92–1.71], total serum bilirubin (HR:1.66;95% CI: 1.28–2.14), serum sodium (HR: 0.94;95%CI: 0.90–0.98), history of hypertension (HR: 2.52;95% CI:1.44–4.41) and hepatic encephalopathy (HR: 2.06;95%CI: 1.13–3.73). The nomogram had a higher concordance(0.79) compared with the model end-stage liver disease(0.67) or Child-Turcotte-Pugh (0.71) score. The nomogramalso showed acceptable calibration (calibration slope, 1.12;Bier score, 0.15±0.21) and optimal clinical net benefit in thevalidation cohort. Conclusions: This prediction model developedbased on characteristics of first-ever SBP patientsmay benefit the prediction of patients’ 1-year survival.
