摘    要:目的 调查酒精性肝病(ALD)患者血清细胞因子水平和肠道菌群分布变化情况。方法 本研究纳入34例ALD患者和34例健康人,采用ELISA法检测血清肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)和核因子κB (NF-κB)水平,采用Celsis ® Advance IITM快速微生物检测系统检测肠道菌落数。结果 ALD患者空腹血糖(FBG)、总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白(LDL-C)和高密度脂蛋白(HDL-C)水平分别为(5.3±1.8)mmol/L、(2.3±0.9) mmol/L、(5.1±1.8) mmol/L、(2.1±0.6) mmol/L和(0.9±0.2) mmol/L,与健康人的(5.2±1.3)mmol/L、(2.2±1.1) mmol/L、(5.1±1.6) mmol/L、(2.0±1.5) mmol/L和(0.8±0.1) mmol/L比,差异无统计学意义(P>0.05);ALD患者血清谷丙转氨酶(ALT)、谷草转氨酶(AST)、谷氨酰转肽酶(GGT)和总胆红素(TBIL)水平分别为(99.5±41.8) U/L、(106.9±55.7) U/L、(229.4±148.3) U/L和(35.3±8.6) μmol/L,显著高于健康人【分别为(35.6±9.7)U/L、(36.2±8.4) U/L、(46.7±14.5) U/L和(16.4±2.3) μmol/L,P<0.05】;ALD患者血清TNF-α、IL-6和N F-κB 水平分别为(9.8±3.4) ng/L、(0.9±0.4) pg/mL和(3.7±6.3) ng/L,显著高于健康人【分别为(5.7±2.1) ng/L、(0.5±0.3) pg/mL和(0.5±0.4) ng/L,P<0.05】;ALD患者粪便粪肠球菌和大肠埃希菌数分别为【(8.7±1.4) lg CFU/g和(7.6±1.2)lg CFU/g】,显著高于健康人【分别为(7.2±1.3) lg CFU/g和(6.6±1.5) lg CFU/g,P<0.05】,而双歧杆菌数为(7.1±1.2)lg CFU/g,显著低于健康人【(8.9±1.3) lg CFU/g,P<0.05】。结论 相对于健康人群,ALD患者存在肠道菌群和血清细胞因子水平紊乱现象,可能参与了疾病的发生发展过程。

Abstract:Objective The purpose of this study was to investigate the changes of serum cytokines and intestinal flora distribution in patients with alcoholic liver disease(ALD).Methods 34 patients with ALD and 34 healthy individuals were recruited in our hospital,and serum tumor necrosis factor-α(TNF-α),interleukin-6 and NF-κB levels were detected by ELISA. The intestinal flora distribution were separated and characterized.Results Fasting blood glucose,total cholesterol,TG,LDL-C and HDL-C levels in patients with ALD were(5.3±1.8) mmol/L,(2.3±0.9) mmol/L,(5.1±1.8) mmol/L,(2.1±0.6) mmol/L and(0.9±0.2) mmol/L,not significantly different as compared to(5.2±1.3) mmol/L,(2.2±1.1)mmol/L,(5.1±1.6) mmol/L,(2.0±1.5) mmol/L and (0.8±0.1) mmol/L in the healthy persons(P>0.05);serum ALT,AST,GGT and bilirubin levels were(99.5±41.8) U/L,(106.9±55.7) U/L,(229.4±148.3) U/L and(35.3±8.6) μmol/L,significantly higher than【(35.6±9.7) U/L,(36.2±8.4) U/L,(46.7±14.5) U/L and(16.4±2.3) μmol/L,respectively,P<0.05】 in the control;serum TNF-α,IL-6 and N F-κB levels were (9.8±3.4) ng/L,(0.9±0.4) pg/mL and(3.7±6.3) ng/L,much higher than 【(5.7±2.1) ng/L,(0.5±0.3) pg/mL and (0.5±0.4) ng/L,P<0.05】 in the control;the enterococcus faecalis and escherichia Coli counts in patients with ALD were (8.7±1.4) lg CFU/g/g and (7.6±1.2) lg CFU/g/g significantly higher than (7.2±1.3) lg CFU/g/g and (6.6±1.5) lg CFU/g/g,respectively,P<0.05] in the control,while the bifidobacterium counts were(7.1±1.2) lg CFU/g/g,much lower than (8.9±1.3) lg CFU/g/g,P<0.05] in the control. Conclusion The intestinal flora disorders and high levels of serum cytokines exist in patients with ALD,which might take part in the pathogenesis of the disease.
