[摘要]意图 探討酒精性肝硬化患者血清脂肪因子的临床含义。办法 将2014年3月~2016年3月于河北省沧州市中心医院住院治疗的52例酒精性肝硬化患者作为肝硬化组,其间Child-Pugh分级A级17例,B级20例,C级15例;一起挑选32名健康体检者作为对照组。检测并比较肝硬化组及不同Child-Pugh分级的肝硬化患者与对照组的血清网膜素、脂联素、内脏脂肪素及其他相关的临床生化参数;选用Spearman等级相关剖析法及线性回归方程剖析酒精性肝硬化患者血清脂肪因子与各生化目标的相关性。成果 肝硬化组患者血清网膜素、脂联素水平分别为(925.19±167.58)ng/L和(908.06±156.96)μg/L,显着高于对照组[(793.68±100.38)ng/L、(649.97±105.01)μg/L](P<0.05);肝硬化组患者内脏脂肪素水平为(18.61±3.75)μg/L,显着低于对照组[(23.39±6.15)μg/L](P<0.05);Child-Pugh分级A、B、C级肝硬化组患者间网膜素、脂联素、内脏脂肪素比较差异均无统计学含义(P>0.05),而跟着Child-Pugh分级A、B、C级的逐步增高,肝硬化组患者的HOMA-IR和IL-6水平也逐步升高(P<0.05)。相关性剖析成果显现,肝硬化组患者血清网膜素、脂联素、内脏脂肪素水平与胰岛素反抗指数及胰岛素水平无显着相关性(P>0.05)。定论 肝硬化时网膜素、脂联素升高,内脏脂肪素下降,其可作为猜测肝硬化的目标,但不能作为肝功用严峻程度的点评目标。

[Abstract]Objective To investigate the clinical significance of serum adipocyte factors in patients with alcoholic cirrhosis.Methods 52 patients with alcoholic cirrhosis from March 2014 to March 2016 in the Central Hospital of Cangzhou City were selected as liver cirrhosis group,among which 17 cases of class A of Child-Pugh grading,20 patients with class B,15 cases of grade C;and 32 healthy controls were selected as control group at the same time.Levels of serum omentin,adiponectin,visfatin and other related clinical and biochemical parameters were measured and compared between patients with liver cirrhosis,different Child-Pugh class of liver cirrhosis and control group.Spearman rank correlation analysis and equation of linear regression were used to analyzed the relationship between cirrhosis serum fat factors and the related biochemical indicators of patients with alcoholic liver.Results The levels of serum omentin and adiponectin in the liver cirrhosis group [(925.19±167.58) ng/L,(908.06±156.96) μg/L] were significantly higher than those of the control group [(793.68±100.38) ng/L,(649.97±105.01) μg/L] (P<0.05),level of serum visfatin in the liver cirrhosis group [(18.61±3.75) μg/L] was significantly lower than that of the control group [(23.39±6.15) μg/L] (P<0.05).The levels of serum omentin,adiponectin,visfatin of patients with different Child-Pugh grading of liver cirrhosis had no statistically significant difference (P>0.05).As the increase of Child-Pugh grading,the levels of group of insulin resistance index and IL-6 increased gradually in patients of the liver cirrhosis group (P<0.05). Correlation analysis results show that,there was no significant correlation between the levels of adiponectin,omentin,visfatin and insulin resistance index in the liver cirrhosis group.Conclusion The levels of serum adiponectin,omentin evidently increase and the level of serum visfatin decrease in patients with alcoholic cirrhosis,and can be a prediction index of liver cirrhosis,but which cant be use to evaluate the degree of liver cirrhosis.

长期以来,脂肪组织一向被以为是仅能供能量储藏的终末分解器官。现在发现脂肪组织能够排泄多种脂肪因子,参加多种病理生理进程,脂肪因子在肝脏的脂肪变性、炎性坏死及纤维化、硬化方面起着重要效果。酒精性肝硬化是我国常见病,其本质为代谢性疾病。本研讨调查了酒精性肝硬化患者血清网膜素、脂联素及内脏脂肪素(visfatin)水平的改变,并剖析了其与肝功用、Child-Pugh分级、胰岛素反抗指数(HOMA-IR)、白介素-6(IL-6)等要素间的联系,现报导如下。

1材料与办法

1.1一般材料

挑选2014年3月~2016年3月于河北省沧州市中心医院(以下简称“我院”)消化内二科住院的酒精性肝硬化患者52例为研讨目标(肝硬化组),一切患者均有清晰的喝酒史、典型的CT体现以及门脉高压症的体现(如腹水、静脉曲张、脾功用亢进等)。其间男40例,女12例;Child-Pugh分级A级17例,B级20例,C级15例。扫除兼并肾功用危害、心肺功用不全、代谢性疾病的患者。一起挑选我院同期健康体检者32例作为对照组,其间男26例,女6例。

1.2目标测定

搜集隔夜空腹8 h以上静脉血,用全自动生化仪检测肝功用、空腹血糖(FPG)、血脂、IL-6,查看凝血惯例,经电化学发光法测定空腹胰岛素(FIns),搜集血清经ELISA法查看网膜素、脂联素、visfatin。体重指数(BMI)=体重/身高2。选用HOMA-IR点评胰岛素反抗,HOMA-IR=FBG×FIns/22.5。

1.3统计学办法

选用SPSS 13.0统计学软件进行数据剖析,计量材料数据用均数±标准差(x±s)表明,多组间比较选用单要素方差剖析,组间两两比较选用LSD-t查验;选用Spearman等级相关剖析法及线性回归方程剖析酒精性肝硬化患者血清脂肪因子与各生化目标的相关性;以P<0.05为差异有统计学含义。

2.1肝硬化组与对照组的一般状况

肝硬化患者丙氨酸氨基转移酶、天冬氨酸氨基转移酶、总胆红素、凝血酶原时刻、FIns、HOMA-IR、脂联素、网膜素、IL-6均高于对照组,差异均有统计学含义(P<0.05);肝硬化患者visfatin、白蛋白、三酰甘油均低于对照组,差异均有统计学含义(P<0.05);两组年纪、体重指数及FPG比较,差异均无统计学含义(P>0.05)(表1)。

2.2不同Child-Pugh分级肝硬化组患者及对照组各血清脂肪因子水平比较

肝硬化组Child-Pugh分级A、B、C级患者血清网膜素、脂联素、HOMA-IR及IL-6水均匀较对照组显着升高,差异均有统计学含义(P<0.05),visfatin较对照组下降,差异有统计学含义(P<0.05)。而Child-Pugh分级A、B、C级肝硬化组患者间网膜素、脂联素、visfatin比较差异均无统计学含义(P>0.05),而跟着Child-Pugh分级的逐步增高,肝硬化组患者的HOMA-IR和IL-6水平也逐步升高(P<0.05),C级患者显着高于A、B级患者,B级患者高于A级患者,差异均有统计学含义(P<0.05)(表2)。

2.3相关性剖析

网膜素、脂联素、visfatin水平与HOMA-IR、FIns水平无显着相关性(P>0.05),与其他各项目标也无线性联系。

网膜素是一种新的脂肪因子[1],能够进步胰岛素的敏感性,是一种有利的脂肪因子[2]。网膜素在非酒精性脂肪性肝病(non alcoholic fatty liver disease,NAFLD)患者血清中下降,原因考虑为NAFLD患者存在胰岛素反抗,但网膜素水平与HOMA-IR无显着相关性[3-4]。肝硬化血清网膜素水平升高,与Child-Pugh分级及HOMA-IR无关,或许原因如下:①体重下降时HOMA-IR下降,网膜素水平升高,肝硬化时,随Child-Pugh分级加剧,营养不良程度加剧并导致消瘦,形成网膜素上升。②网膜脂肪组织网膜素mRNA水平与循环中雌二醇水平呈负相关[5],肝硬化患者体内雌激素水平升高,且随Child-Pugh分级加剧而升高,或许形成网膜素水平下降,而未随Child-Pugh分级加剧而升高。③肝硬化时腹膜及大网膜水肿[6];④肝硬化为一种炎症性疾病,网膜素在炎症性疾病时升高。

脂联素是由白色脂肪组织的老练脂肪细胞特异性组成排泄的脂肪因子,是胰岛素增敏剂,在NAFLD中,APN水平下降[7]。本研讨发现肝硬化患者尽管存在胰岛素反抗,且随Child-Pugh分级加剧而加剧,但血清脂联素水平却较对照组升高,其原因或许为:①肝硬化时对脂联素的代谢铲除削减[8];②肝细胞受损时脂联素mRNA及其蛋白表达添加[9];③缓慢肝病胆汁淤积,胆汁排出削减[10]。

visfatin是由脂肪组织排泄的一种脂肪因子,可加剧胰岛素反抗。NAFLD患者visfatin上升,当发作非酒精性脂肪性肝炎时,visfatin水平下降,但较对照组升高[11]。visfatin基因在正常肝脏低表达,在重度肝纤维化中添加,一起在缓慢肝危害患者中表达上调,在酒精性肝病中visfatin表达与炎症和纤维化程度密切相关。现在以为,visfatin可诱导IL-6的排泄[12],一起,IL-6也能调理visfatin mRNA在脂肪细胞中的表达[13],两者相互效果。本研讨发现,肝硬化患者visfatin水平下降,原因首要为肝硬化时肝细胞visfatin mRNA表达下降,其水平改变或许如下:①肝硬化时大都存在胰岛素反抗,而且随Child-Pugh分级加剧而加剧,胰岛素反抗时visfatin水平上升,部分抵消了胰岛素反抗;②肝硬化患者内脏脂肪削减;③肝硬化多存在低氧血症,而低氧、缺氧状况下机体内氧稳态的首要调理因子低氧诱导因子-1高表达,可直接上调visfatin的表达;④IL-6水平升高而上调visfatin水平;⑤visfatin在各种炎症时均升高,肝硬化本身为一种炎症性疾病[14];⑥肝硬化大都患者存在营养不良,而营养不良时visfatin水平上升,原因或许為visfatin能够促进体内烟酰胺的组成,而烟酰胺对营养状况的改进有必定效果[15]。

综上所述,本研讨发现网膜素、脂联素在酒精性肝硬化时升高,visfatin下降,且与HOMA-IR无关,因而网膜素、脂联素及visfatin可作为肝硬化的猜测目标,但不能作为肝功用严峻程度的点评目标,如检测酒精性肝硬化患者血清网膜素、脂联素、visfatin水平,应从多方面考虑或许影响要素,归纳剖析,然后得出更合理的定论来辅导临床。
