Among these patients, 258 patients had secondary acute cholangitis and served as observation group, and the remaining 569 choledocholithiasis patients served as the control group. Serum liver function indexes and tumor markers were detected in both groups, and the receiver operating characteristic(ROC) curves were constructed for markers showing statistical significances. The cutoff value, sensitivity, and specificity of each marker were calculated according to the ROC curves. RESULTS The results of liver function tests showed no significant differences between the two groups(P > 0.05). Tumor markers including serum CA125, CA153, carcinoembryonic antigen, and alpha fetoprotein levels were also not significantly different(P > 0.05); however, the serum CA199 level was significantly higher in the observation group than in the control group(P < 0.05). The ROC curve analysis showed that the area under the curve was 0.885(95%CI: 0.841-0.929) for CA199, and the cutoff value of 52.5 kU/L had the highest diagnostic accuracy, with a sensitivity of 86.8% and a specificity of 81.6%.CONCLUSION Abnormally elevated serum CA199 level has an important value in the diagnosis of acute cholangitis secondary to choledocholithiasis. It may be a specific inflammatory marker for acute cholangitis.展开更多

Methods： 55 patients with chronic AF and 58 control patients in sinus rhythm were included into the study. Patients with acute heart failure （HF）, chronic inflammatory or neoplastic disease were excluded from the study. Circulating levels of CA-125 were assessed; all patients underwent clinical examination, assessment and medical records including demographic data, history of comorbid conditions, current use of cardiac medications, and the results of cardiac tests including electrocardiograms. Results： The mean age of the study sample was 53.2±6.5 years and 48% were men. Patients with sinus rhythm were significantly more likely to have lower heart rates, smaller dimensions of left atrium, and to be treated with aspirin. Coumadin, coumadin and digoxin were more often prescribed in patients with chronic AF. The CA-125 levels were significantly higher in patients with chronic AF than in patients in sinus rhythm （48.5±7.65 U/ml and 28.43±5.48 U/ml, P〈0.005）. An inverse relation was found between CA-125 levels and left ventricular ejection fraction （LVEF） （r=-0.48, P〈0.001）. CA-125 was significantly related to the left atrium （LA） diameter, left ventricular end-diastolic diameter （LVEDD）, left ventricular end-systolic diameter （LVESD） and brain natriuretic peptide （BNP）. There was no significant correlation between CA-125 and age. Conelusion： In subjects with chronic AF, CA-125 levels are increased; CA-125 was significantly related to the LA diameter, LVEDD, LVESD and BNP.展开更多
