RESUMO
Objective:To investigate the early evaluation potential of serum levels of apolipoprotein B/apolipoprotein A1 (Apo B/A1), microtubule-associated protein 1-light chain 3 (MAP1-LC3) and intercellular adhesion molecule-1 (ICAM-1) in acute pancreatitis (AP) patients.Methods:A total of 413 AP patients who were treated at the Second Affiliated Hospital of Anhui Medical University between January 2019 and August 2020 were enrolled. Serum samples were collected from AP patients within 24 h of admission. Patients were divided into the non-severe acute pancreatitis (Non-SAP, n=315) and severe acute pancreatitis (SAP, n=98) groups according to the severity of the disease. Sixty healthy controls were recruited. The differences of serum Apo B/A1, MAP1-LC3 and ICAM-1 among the three groups were compared by one-way analysis of variance, and the correlation between Apo B/A1, MAP1-LC3 and ICAM-1 and the severity of AP was analyzed by Pearson correlation analysis. Sensitivity and specificity in assessing AP severity were predicted by receiver operating characteristic curve (ROC). Results:The early levels of Apo B/A1, MAP1-LC3 and ICAM-1 were all significantly higher for AP patients than for healthy controls ( P<0.05), and the levels of Apo B/A1, MAP1-LC3 and ICAM-1 in SAP patients were significantly higher than those in non-SAP patients[Apo B/A1: 2.21±1.40 vs. (0.96±0.34); MAP1-LC3: 0.92±0.29 vs. (0.48±0.24) ng/mL and ICAM-1: (235.57±54.50 ) vs. (120.28±61.69)ng/mL; P<0.05]. Pearson correlation analysis showed that levels of Apo B/A1, MAP1-LC3 and ICAM-1 were positively correlated with the first Ranson score after admission ( P<0.05), and ICAM-1 showed the highest degree of correlation with AP severity ( r=0.519). Areas under the receiver operating characteristic curve (AUROC) were 0.769 for Apo B/A1, 0.811 for MAP1-LC3, 0.828 for ICAM-1, and 0.938 for combined detection. Conclusions:Serum levels of Apo B/A1, MAP1-LC3 and ICAM-1 within 24 h after admission are significantly correlated with the severity of AP, which has clinical significance for early prediction of the severity of AP.
RESUMO
Objective To explore the evaluation value of serum Ghrelin and pleural effusion in patients with acute pancreatitis . Methods Eighty patients with acute pancreatitis treated in our hospital from February 2011 to February 2014 were divided into mild case group (31 patients) and severe case group (49 patients) according to the severity of the disease .Venous blood samples were collected at time point including :admission ,48h after admission and after discharge at empty stomach in the morning ,and CRP level ,WBC ,PCT level of patients were checked .The concentration of serum Ghrelin of patients were mensurated by enzyme linked immunosorbent assay and pleural effusion were diagnosed by sternum .Results Compared with the patients in the mild case group , serum Ghrelin ,CRP level ,APACHE score ,CT score and Ranson score were higher in the severe case group and the hospital day of patients in the severe case group was longer(P<0 .01) .The area under the curve of CRP level ,pleural effusion ,Ghrelin ,Ghrelin combined with pleural effusion of ROC were 0 .708 3 ,0 .749 6 ,0 .852 4 and 0 .910 8 .Ghrelin combined with pleural effusion has the best evaluation effect on the patients with acute pancreatitis .The sensibility ,specificity ,accuracy of CRP were 93 .6% ,69 .4% and 73 .7% ;the sensibility ,specificity ,accuracy of pleural effusion were 75 .2% ,88 .7% and 76 .8% ;the sensibility ,specificity ,accuracy of Ghrelin were 86 .9% ,88 .2% and 85 .3% ;the sensibility ,specificity ,accuracy of Ghrelin combined with pleural effusion were 90 .1% ,92 .6% and 91 .4% .Conclusion Serum Ghrelin and pleural effusion have high sensibility ,specificity and accuracy in pa‐tients with acute pancreatitis and has high clinical value .
RESUMO
Objective To explore the value of peripheral blood serum levels of PCT,CRP,TNF-α and free DNA of cells in predicting the development of MODS in patients with multiple trauma.Methods Complete detail clinical data of 54 casualties with multiple trauma admitted within 24 hours after accident from January 2011 through January 2012 were collected for retrospective study.The patients were divided into MODS group and non-MODS group according the criteria set forth by the Chinese Society of Critical Care and Emergency Medicine in 1995 national conference.The data of two groups are comparable,and data of another 20 healthy subjects undertaking routine annual physical examination were taken as control.The peripheral blood levels of PCT,CRP,TNF-α and free DNA of patients of two groups were determined 1 d,2 d,3 d,and 5 days after admission.Then the results were analyzed and compared between groups.Results Compared with non MODS group,the levels of PCT,CRP,free DNA of cells in MODS group were significantly higher (P ＜ 0.05),but there was no deference in TNF-α between MODS group and non-MODS group (P ＞ 0.05).When the relative risks of increased PCT (PCT≥6 mg/L),increased CRP (CRP≥ 130 mg/L)、and increased free DNA of cells (free DNA ≥ 10 0005/L) were analyzed,the presence of these 3 biomarkers with high levels occurred at the same time was the most accurate way to predicts MODS in 6.00 relative risk (RR),and the positive predictive value was 100％.Conclusions PCT,CRP,free DNA of cells could be the predictors of MODS in patients with severe multiple trauma,and the presence of high levels of these three biomarkers appearing together had high sensitivity and specificity for prediction.
