摘要: 目的 探讨双黄连对病毒感染诱导的暴发性肝衰竭小鼠的保护作用。方法 取BABL/cJ小鼠36只,随机均分为对照组、模型组和双黄连处理组。取滴度为1×106 PFU/ml的3型鼠肝炎病毒(MHV-3),采用高压水注射法经小鼠尾静脉注入小鼠体内,诱导暴发性肝衰竭模型。在造模后给予10%双黄连或生理盐水灌胃治疗7 d。采用RT-PCR法检测小鼠肝组织IP-10 mRNA和血清MHV-3 DNA水平,并检测血清转化生长因子-βl(TGF-βl)、白细胞介素-10(IL-10)、层黏连蛋白(LN)、透明质酸(HA)和肝功能指标。结果 在治疗7 d,模型组和双黄连组小鼠血清谷丙转氨酶(ALT)分别为(229.03±30.56) IU/L和(22.83±6.02) IU/L,谷草转氨酶(AST)为(139.01±11.75) IU/L和(32.45±4.59) IU/L,LN分别为(99.86±10.57) nmol/L和(57.02±7.24) nmol/L,HA为117.05±16.72) nmol/L和(53.01±11.35) nmol/L,TGF-βl分别为(319.46±39.12) pg/ml和(93.87±11.20)pg/ml,IL-10为25.70±3.87) pg/ml和(1.07±0.09) pg/ml, MHV-3 DNA分别为12.47±3.05) lg copies/mL和(1.24±0.10)lg copies/mL,肝组织IP-10 mRNA分别为【(25.70±3.87)和(12.79±3.08),P<0.05】。结论 双黄连有一定的抗MHV-3作用,可能是通过抑制肝内IP-10 mRNA水平,减少IL-10对肝细胞的炎性损伤,阻止了肝组织纤维化而促进了肝功能的恢复。

Abstract: Objective To investigate the protective effects of Shuanghuanglian,a herbal compound,in mice with murine hepatitis virus strain 3(MHV-3)-induced fulminant liver failure (FLF). Methods 36 BABL/36 cJ mice were randomly divided into control,model and Shuanghuanglian-intervened group,and the model of FLF was established by intravenous injection of 1×106 PFU/ml MHV-3. 10% of Shuanghuanglian compound or normal saline was given by gavage for 7 days after the model was successfully established. The chemokine IP-10 mRNA in liver tissues and serum MHV-3 DNA loads were quantitatively assayed by RT-PCR,and serum transforming growth factor beta 1(TGF- beta 1),interleukin-10 (IL-10),laminin(LN),hyaluronic acid (HA) and liver function index were detected routinely. Results Serum ALT levels in the model and Shuanghuanglian-intervened group at end of 7 days were (229.03±30.56) U/L and (22.83±6.02) IU/L,AST were (139.01±11.75) U/L and (32.45±4.59) U/L. LN were (99.86±10.57) nmol/L and (57.02±7.24) nmol/L, HA were (117.05±16.72) nmol/L and (53.01±11.35)nmol/L,TGF-beta l were (319.46±39.12) pg/ml and (93.87±11.20) pg/ml,IL-10 were (25.70±3.87) pg/ml and(1.07±0.09) pg/ml,MHV-3 DNA were(12.47±3.05) lg copies/mL and(1.24±0.10) lg copies/mL,and IP-10 mRNA in liver tissues were[(25.70±3.87)and(12.79±3.08),P<0.05]. Conclusion Shuanghuanglian,a herbal compound,has a certain effect of anti MHV-3 virus,and the mechanism by which it works might be through inhibiting the expression of IP-10 mRNA,reducing the inflammatory damage of IL-10 to the hepatocytes,preventing liver fibrosis and promoting the recovery of liver functions.
