Materials and Methods: This study comprised 41 cirrhotic patients with ascites. MPV, PDW and MIP-1β were measured in serum and ascitic fluid. Results: A significant increase MPV, PDW, C-reactive Protein (CRP) and white blood cell was observed in SBP group compared to non SBP (P ≤ 0.001, P = 0 β was significantly in-creased in ascitic fluid in patients with SBP versus non SBP (P ≤ 0.001). At cutoff value of 8.3 fl MPV had 85.7% sensitivity and 75% specificity (AUC = 0.876) for diagnosis of SBP. At cutoff value of 15.4 PDW had 90.4% sensitivity and 55% specificity (AUC = 0.762). At cutoff value of 121.9 pg/ml MIP-1β in ascitic fluid had 76.1% sensitivity and 100% specificity (AUC = 0.881) for detecting SBP. Conclusion: MIP-1β and platelet indices are useful marker in the diagnosis of SBP in cirrhotic patients. Combined measurement of MIP-1β in serum and ascitic fluid had 100% sensitivity and specificity for diagnosis of SBP.展开更多

文摘目的探究血清血管内皮生长因子受体1(vascular endothelial growth factor receptor-1,VEGFR-1)和巨噬细胞炎性蛋白-3α(macrophage inflammatory protein-3α,MIP-3α)在子宫内膜异位症(endometriosis,EMs)患者中的表达以及两者联合检测对EMs患者术后复发的预测价值。方法选取2019年4月~2021年6月秦皇岛市妇幼保健院行腹腔镜手术治疗的114例EMs患者作为观察组,同期选择在该院体检的孕龄期女性114例健康体检者作为对照组。采用酶联免疫吸附法(ELISA)测定患者血清中VEGFR-1和MIP-3α水平;根据术后二年复发情况,将其分为复发组(n=78)和未复发组(n=36)。采用多因素Logistic回归分析EMs患者术后复发的影响因素;采用受试者工作特征(receiver operating characteristic,ROC)曲线分析血清VEGFR-1与MIP-3α联合检测对EMs患者术后复发的预测价值。结果与对照组相比,观察组VEGFR-1(116.25±48.57pg/ml vs 92.43±25.37pg/ml)及MIP-3α(19.25±5.24pg/ml vs 13.67±4.28pg/ml)水平升高,差异具有统计学意义(t=4.641,8.806,均P<0.05)。轻度、中度、重度EMs患者VEGFR-1水平(104.22±5.78pg/ml,118.60±6.56pg/ml,138.55±7.85pg/ml)和MIP-3α水平(15.37±1.15pg/ml,19.28±2.12pg/ml,25.42±2.56pg/ml)依次升高,差异具有统计学意义(F=147.757,133.654,均P<0.001)。复发组中后穹隆存在触痛结节及r-AFS分期(Ⅲ~Ⅳ期)占比显著大于未复发组(χ^(2)=15.139,10.310,均P<0.05);复发组术后用药6个月及以上占比显著低于未复发组(χ^(2)=15.016,P<0.001),差异具有统计学意义。多因素Logistic回归分析显示,血清VEGFR-1,MIP-3α,后穹隆存在触痛结节及r-AFS分期为EMs术后复发的危险因素(均P<0.05),术后用药6个月及以上为保护因素(P<0.05)。ROC曲线显示,血清VEGFR-1与MIP-3α联合预测EMs术后复发的曲线下面积(area under the curve,AUC)最大(0.929),其敏感度和特异度分别为85.90%和86.11%。结论VEGFR-1及MIP-3α在EMs患者血清中表达升高,且二者联合检测在预测EMs术后复发的效能更佳。
