RESUMO
Objective To investigate the clinical diagnostic value of serum procalcitonin(PCT),D-dimer (DD),C-reactive protein(CRP)in acute-on-chronic liver failure(ACLF). Methods 124 ACLF patients, 63 chronic hepatitis B patients,32 chronic hepatitis C patients,24 chronic hepatitis E patients and 60 healthy controls from the second affiliated hospital of Nanchang University were enrolled in this study.PCT was detected by a sandwish immunodetection method. D-dimer was detected by Latex Turbidimetry. CRP was detected by rate nephenometry. The detection results were used for analyzing the clinical diagnostic value of ACLF with infection. Results(1)The level of PCT,DD and CRP in ACLF group were significantly higher than non-ACLF group and healthy controls(P<0.05).The levels of PCT,DD and CRP in the infection group were significantly higher than non-infection group(P<0.05).(2)The positive rates of PCT,DD and CRP in the infection group were 93.24%, 78.38%,89.19%,which were significantly higher than the non-infection group and healthy controls respectively (P < 0.05).(3)The sensitivity(93.24%)and specificity(90.00%)of PCT were the highest among all indexes. (4)The area under the ROC curve of PCT,DD,CRP were 0.892,0.715,0.755,respectively.PCT had the highest diagnostic value. Conclusion The levels of serum PCT,DD and CRP have a significant clinical value for the early diagnosis of ACLF with infection.
RESUMO
Objective:To explore combined detection of mad2 with anti-nuclear mitotic spindle apparatus antibody(MSA)and anti-centromere antibody(ACA)and their clinical value for the diagnosis of small cell lung cancer(SCLC).Methods:One hundred and twen-ty SCLC patients,110 non-small cell lung cancer(NSCLC)patients,and 115 pulmonary nodule(PN)patients were enrolled in this study. The expression of mad2 was analyzed by qt-PCR.MSA and ACA were detected by indirect immunofluorescence(IIF)staining.Results:mad2 was overexpressed in SCLC and NSCLC samples(P<0.05).There were significant differences between the results obtained for SCLC and NSCLC samples by qt-PCR(P<0.05).AUC in ROC curve for mad2 expression was 0.799 with an intermediate diagnostic value. In the correlative analysis,the odds ratio of MSA and ACA was 6.94 and 5.60,respectively.In the correlation analysis,Kappa value of mad2 with MSA was 0.49,and Kappa value of mad2 with ACA was 0.42.In the parallel analysis,the sensitivity and specificity was 83.31% and 79.34%,respectively,while the Youden Index was 0.62.Moreover,in the serial analysis,the sensitivity and specificity was 65.32% and 93.35%,respectively,and the Youden Index was 0.59.Conclusions:In comparison with the NSCLC and PN samples,mad2 was overexpressed in SCLC samples.Therefore,mad2 ought to play a critical role in the pathology of SCLC.The combined expression of mad2 with MSA and ACA may contribute to enhancing the sensitivity and specificity of detection;this expression may allow early diag-nosis and clinical diagnosis of SLCC and may be a promising treatment for SCLC.
