Objective To investigate predictive value of procalcitonin (PCT) and C-reactive protein (CRP) levels for spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis ascites. Methods The clinical data of 140 patients with liver cirrhosis ascites treated in our hospital from January 2012 to January 2016 were retrospectively analyzed. According to the presence of SBP, these patients were divided into SBP group and non-SBP group. The clinical data were compared between these two groups. The receiver operating characteristic (ROC) curve was constructed to assess their sensitivities and specificities of PCT and CRP for diagnosis of SBP. Results The PCT and CRP levels of the SBP group were significantly higher than those of the non-SBP group (P<0.05). The differences of serum ALT, AST and white cell count between the SBP group and the non-SBP were not statistically significant (P>0.05). The ROC curve analysis showed that the area under the ROC curve of PCT and CRP were 0.895 and 0.926, their corresponding cut-off value 2.1 μg/L and 24.8 mg/L, the sensitivities were 86.9% and 89.5%, the specificities were 85.1% and 83.5%, respectively. Conclusion Abnormally elevated PCT and CRP levels might have an important detective value for SBP in patients with liver cirrhosis ascites.
目的 研究细胞视黄酸结合蛋白（CRABP）Ⅱ、表皮型脂肪酸结合蛋白（E-FABP）和Ki-67在乳腺浸润性导管癌中的表达情况及三者的相关性。 方法 采用免疫组织化学检测2001年1月－2007年12月手术切除的152例乳腺浸润性导管癌中CRABPⅡ、E-FABP和Ki-67的表达。 结果 在浸润性导管癌中，CRABPⅡ在Ki-67阴性组的阳性率高于Ki-67阳性组（P＜0.05），相反地，E-FABP在Ki-67阳性组的阳性率高于Ki-67阴性组（P＜0.05）。CRABPⅡ和Ki-67表达呈负相关（rS=?0.432，P＜0.05）；E-FABP和Ki-67表达呈正相关（rS=0.842， P＜0.05）。E-FABP和Ki-67的表达具有协同性，E-FABP和Ki-67共同表达与肿瘤的转移有关（P＜0.05）。单因素生存分析显示，E-FABP的阳性表达患者、Ki-67的阳性表达患者以及E-FABP和Ki-67的共同阳性表达患者的预后差（P＜0.05）。多因素生存分析提示E-FABP的表达（RR=4.223，P=0.012）和TNM分期（RR=8.412，P=0.000）是影响浸润性导管癌患者预后的独立危险因素。 结论 在乳腺浸润性导管癌中，CRABPⅡ和E-FABP与肿瘤细胞的增殖有关，CRABPⅡ抑制细胞增殖，E-FABP促进细胞增殖。E-FABP和Ki-67在浸润性导管癌的发生、发展中起协同作用，两者的阳性表达可能对评估肿瘤的转移和患者的预后有一定价值。
