摘　　要：长期饮酒或者短期内摄入大量酒精会导致肝脏损伤,酒精性肝病在世界范围内十分常见。急性酒精损伤主要通过酒精代谢和活性氧(reactive oxygen species,ROS)导致的细胞毒性效应从而引起细胞死亡。王氏保赤丸具有排瘀化浊、解热镇静、健胃消食、泻火解毒等多种效用,临床应用十分广泛。该研究主要探讨王氏保赤丸是否对急性酒精肝损伤小鼠醒酒及护肝/胃有作用,且初步研究了其可能的分子机制。研究发现,王氏保赤丸预防给药可以升高乙醇脱氢酶(alcohol dehydrogenase,ADH)活性及肝脏中ADH的表达,从而缩短急性酒精性损伤小鼠的醒酒时间。通过对急性酒精性损伤小鼠的肝脏病理切片染色和血清生化指标谷丙转氨酶(alanine aminotransferase,ALT)与谷草转氨酶(aspartate aminotransferase,AST)的活力检测发现,王氏保赤丸具有保护肝脏的作用,可以降低小鼠血清AST、ALT水平。同时,该研究发现王氏保赤丸可以通过降低肝脏ROS水平、升高超氧化物歧化酶(superoxide dismutase,SOD)减少氧化应激造成的肝损伤,且效果优于护肝药水飞蓟宾。进一步的Western blot实验分析发现,王氏保赤丸可以升高SOD1、NADPH醌氧化还原酶1[NAD(P)H:quinone oxidoreductase 1,NQO-1]的表达水平,起到抗氧化应激的作用。此外,王氏保赤丸也可以通过降低ROS水平对急性酒精性损伤小鼠的胃部起到保护作用。以上研究表明,王氏保赤丸可以通过增加ADH、抗氧化应激保护酒精导致的小鼠急性肝/胃损伤。As a common disease worldwide, alcoholic liver injury is caused by long-term or excessive intake of alcohol and triggers cell death due to alcohol metabolism and reactive oxygen species(ROS)-mediated cytotoxicity. Wangshi Baochi(WSBC) Pills have been widely adopted in clinical practice for evacuating stasis, resolving turbidity, clearing heat, tranquilizing mind, invigorating sto-mach, promoting digestion, purging fire and removing toxin. This study aimed to investigate the efficacy of WSBC Pills in dispelling the effect of alcohol and protecting against acute alcoholic liver/stomach injury in mice, and preliminarily investigate its possible mole-cular mechanism. The results found that the preventive treatment with WSBC Pills contributed to elevating the activity of alcohol dehydrogenase(ADH) and its expression in liver and shortening the time required for sobering up of mice with acute alcoholic liver injury. The staining of liver pathological sections as well as the detection of serum aspartate aminotransferase(AST) and alanine aminotransferase(ALT) and liver ROS levels revealed that WSBC Pills protected the liver by reducing serum AST and ALT. It suppressed oxidative stress-induced liver injury by lowering liver ROS and elevating superoxide dismutase(SOD), and the liver-protecting effect was superior to that of silibinin. Western blot assay confirmed that WSBC Pills inhibited the oxidative stress by up-regulating SOD1 and NAD(P)H: quinone oxidoreductase 1(NQO-1). In addition, WSBC Pills lowered the ROS level to protect against the acute alcoholic stomach injury in mice. The findings have suggested that WSBC Pills alleviated the acute alcoholic liver/stomach injury in mice by increasing ADH and resisting oxidative stress.
