[摘要] 目的 探讨非酒精性脂肪肝病(NAFLD)患者血清中CK18-M65、脂联素水平的相关性。 方法 NAFLD组方便选取2013年2月—2014年6月在宁夏医科大学总院体检诊断为NAFLD的患者98例,另选取同期在该院进行体检的健康人群103名作为对照组,对受试者各项指标进行检测分析。 结果 NAFLD组与对照组相比,体质量指数、血压、腰臀比、血糖、血脂、胰岛素、血尿酸、CK18-M65及脂联素差异有统计学意义(26.91±2.15)kg/m2 vs (23.14±1.92)kg/m2,(125.31±6.84)mmHg vs (114.86±7.10)mmHg,(80.49±3.92)mmHg vs (75.28±4.18)mmHg,(0.92±0.18) vs (0.86±0.21),(5.89±0.61)mmol/L vs (5.44±0.53)mmol/L,(2.26±0.18)mmol/L vs (1.49±0.12)mmol/L,(5.35±0.24)mmol/L vs (5.08±0.31)mmol/L,(1.12±0.08)mmol/L vs (1.31±0.11)mmol/L,(3.12±0.14)mmol/L vs (2.79±0.21)mmol/L,(12.78±0.09)U/mL vs (3.45±0.10)U/mL,(361.54±3.15)μmol/L vs (312.51±2.91)μmol/L,(159.18±3.94)ng/L vs (108.54±4.08)ng/L,(1.60±0.08)μg/mL vs (2.23±0.09)μg/mL (P<0.05)。隨着疾病严重程度的增加,血清CK18-M65及脂联素的表达均显著改变(单纯性脂肪肝组,NASH组,肝纤维化组3组CK18-M65水平分别为(128.14±11.26),(145.62±9.62),(167.15±12.08)ng/L;脂联素水平分别为(1.82±0.28),(1.67±0.19),(1.52±0.34)μg/mL)],CK18-M65与脂联素水平呈显著负相关(r=-0.223,P<0.05)。结论 CK18-M65及脂联素在NAFLD患者中表达异常,且NAFLD患者CK18-M65与脂联素表达呈负相关。

[Abstracts] Objective This paper tries to explore the correlation of non-alcoholic fatty liver disease, CK18-M65 and adiponectin level. Methods Convenient selection 98 cases of non-alcoholic fatty liver disease in this hospital from February 2013 to June. 2014 were selected and divided into NAFLD group. 103 healthy voluntaries in this hospital were selected as control group. The biochemical indexes of the two groups were compared. Results There were significant differences between NASH group and the control group of BMI, blood pressure, WHR, blood glucose, blood fat, insulin, blood uric acid, CK18-M65 and adiponectin of[(26.91±2.15)kg/m2 vs (23.14±1.92)kg/m2, (125.31±6.84)mmHg vs (114.86±7.10)mmHg, (80.49±3.92)mmHg vs (75.28±4.18)mmHg, (0.92±0.18) vs (0.86±0.21), (5.89±0.61)mmol/L vs (5.44±0.53)mmol/L, (2.26±0.18)mmol/L vs. (1.49±0.12)mmol/L, (5.35±0.24)mmol/L vs. (5.08±0.31)mmol/L, (1.12±0.08)mmol/L vs. (1.31±0.11)mmol/L, (3.12±0.14)mmol/L vs. (2.79±0.21)mmol/L, (12.78±0.09)U/mL vs (3.45±0.10)U/mL, (361.54±3.15)μmol/L vs (312.51±2.91)μmol/L, (159.18±3.94)ng/L vs. (108.54±4.08)ng/L, (1.60±0.08)μg/L vs (2.23±0.09)μg/L](P<0.05). The levels of CK18-M65 in the patients with simple fatty liver group, NASH group and hepatic fibrosis group were (128.14±11.26), (145.62±9.62) and (167.15±12.08)ng/L respectively. The levels of adiponectin of the three groups were (1.82±0.28), (1.67±0.19) and (1.52±0.34)μg/mL, and the level of CK18-M65 was significantly negatively correlated with adiponectin (r=-0.223, P<0.05). Conclusion CK18-M65 and adiponectin level was abnormal and CK18-M65 had significantly negative correlation with adiponectin level in patients with non-alcoholic fatty liver disease.endprint

非酒精性脂肪性肝病(NAFLD)是指肝脏出现脂类代谢障碍,平衡失调、蓄积过多的一种病理状态;该病病理学类似于酒精性肝病但患者均并无过量饮酒史;流行病学调查显示,全球范围内NAFLD的发病率为6.3%~33%,已成为全球性的严重的公共卫生问题[1-3]。病理组织学作为NAFLD诊断的金标准,因其有创性且花费大等不能被广大患者接受;因此,NAFLD的无创诊断是近年来热议的话题。细胞角蛋白(CK18-M30)是由NAFLD患者体内凋亡的肝细胞分泌的一种细胞因子,已有研究发现,血清CK-18M30水平在NAS评分中不仅与肝细胞单纯脂肪变、肝小叶炎症呈正相关,还与非酒精性脂肪性肝炎(NASH)的典型组织病理学特征的肝细胞气球样变和Mallory-Denk小体呈正相关[4-5]。故推测CK-18M65对于NAFLD特别是NASH的无创检查有一定的鉴别意义。该研究选择选取2013年2月—2014年6月在宁夏医科大学总院体检诊断为NAFLD的患者98例,与健康对照组人群血清中CK18-M65、脂联素水平进行测定,旨在探讨NAFLD与CK18-M65、脂联素水平的相关性,为NAFLD疾病的诊断提供新的指标,现报道如下。……
