摘要:

目的:通过鸭乙型肝炎病毒(DHBV)阳性血清注射建立鸭乙型肝炎模型,探讨α-2b干扰素治疗DHBV所致鸭肝炎症及肝纤维化的作用,为干扰素的临床应用提供依据。方法:10日龄北京麻鸭40只随机分为对照组(6只)和感染组(34只),感染组使用DHBV阳性血清1周内3次注射的方法,制备鸭乙型肝炎模型。2周后,采用斑点杂交法检测DHBV-DNA水平确认感染鸭共32只,随机将感染动物分为模型对照组(10只)、低剂量及高剂量α-2b干扰素组(各11只),α-2b干扰素组鸭分别肌肉注射低剂量(1×105 U·100 g-1)和高剂量(5×105 U·100 g-1)α-2b干扰素治疗。30 d治疗结束后,采用斑点杂交法检测各组鸭血清DHBV-DNA水平,检测天门冬氨酸氨基转移酶(AST)、谷氨酸氨基转移酶(ALT)和肝纤维化指标层黏蛋白(LN)及Ⅲ型前胶原肽(PCⅢ)水平,取肝组织检测白细胞介素6(IL-6)、白细胞介素12(IL-12)和肿瘤坏死因子α(TNF-α)水平,观察组织病理形态表现。结果:与造模前比较,造模后鸭血清DHBV-DNA水平明显升高,表明造模成功。α-2b干扰素治疗结束后,与模型组比较,低和高剂量α-2b干扰素组鸭血清DHBV-DNA水平明显下降(P<0.05),血清中AST和ALT水平降低(P<0.05),其中高剂量α-2b干扰素组LN及PCⅢ型水平明显降低(P<0.05),肝组织中IL-6和TNF-α水平明显降低(P<0.05),IL-12水平无明显变化(P>0.05)。组织病理形态表现,与模型组比较,低和高剂量α-2b干扰素组鸭肝组织中纤维化明显减轻。结论:α-2b干扰素可以减轻DHBV所致的鸭肝组织炎症和肝纤维化,本研究为干扰素的进一步开发和临床应用提供了理论依据。

Abstract:

Objective: To establish the duck models of hepatitis B by duck hepatitis B virus(DHBV) serum injection method,and to explore the effects of α-2b interferon on the inflammation and liver fibrosisinduced by DHBV,and to provide evidence for its clinical application.Methods: A total of 40 Beijing ducks (aged 10 d) were randomly divided into control(n=6) and infection(n=34) groups.The ducks in infection group were injected with DHBV positive serum for 3 times in 1 week to establish hepatitis B models.Two weeks later,32 ducks were confirmed infection by using DHBV-DNA test method,and randomly divided into model group (n=10),low dose of α-2b interferon group (n=11, 1×105 U·100 g-1) and high dose of α-2b interferon group (n=11,5×105 U·100 g-1).After 30-day treatment,the serum DHBV-DNA levels of the ducks in various groups were detected by dot hybridization method.The levels of glutamic oxalacetic transaminase (AST),glutamic-pyruvic transaminase (ALT),laminin (LN) and type Ⅲ collagen peptide (PCⅢ) in serum were measured,the levels of IL-6,IL-12,and TNF-α in liver tissue were also measured, and the pathological changes of liver tissue were observed.Results: The level of DHBV-DNA was significantly increased compared with pre-modeling. so the DHBV-infected models were successfully established. Compared with model group,the levels of DHBV-DNA in low and high doses of α-2b interferon groups were significantly decreased (P<0.05);the levels of serum AST and ALT in low and high doses of α-2b interferon groups were significantly decreased (P<0.05); the levels of LN and PCⅢ in high dose of α-2b interferon group were significantly decreased (P<0.05);the levels of IL-6 and TNF-α in liver tissue in low and high doses of interferon groups were decreased (P<0.05); but the IL-12 levels have no significant changes (P>0.05).Compared with model group,the liver fibrosis in low and high deses of α-2b interferon groups was improved.Conclusion: α-2b interferon can relieve the inflammation in duck liver tissue induced by DHBV and liver fibrosis. The study provides the theoretical evidence for further development and clinical application of α-2b interferon.
