| 摘 要： | 目的 探讨慢性乙型肝炎（CHB）患者外周血单个核细胞（PBMC）中凋亡分子表达水平及临床意义。方法 以2018年1月至2020年7月郑州市某医院消化内科诊治的CHB患者为研究对象,比较不同病情程度患者PBMC中凋亡分子（Caspase-3、Caspase-6、Caspase-8）mRNA表达量、辅助T细胞（Th）1细胞因子白细胞介素（IL）-2、干扰素γ（IFN-γ）]、Th2细胞因子（IL-4、IL-10）水平,采用Pearson相关性分析凋亡分子与IL-2/IL-10、IFN-γ/IL-4的相关性。根据凋亡分子表达均数分为低表达者、高表达者,比较不同表达CHB患者HBV-DNA载量,并分析凋亡分子与乙型肝炎病毒（HBV）-DNA的关系。结果 本研究共纳入CHB患者116例,男83例,占71.6%。患者年龄27~78岁,以45~59岁所占比例最大,占50.9%。轻、中、重度患者分别为36、45、35例,分别占31.0%、38.8%、30.1%。不同病情程度的CHB患者PBMC中Caspase-3 mRNA、Caspase-6 mRNA、Caspase-8 mRNA表达量差异均有统计学意义（均P<0.01）。重度患者IL-2、IFN-γ、IL-2/IL-10、IFN-γ/IL-4低于中度、轻度患者,IL-4、IL-10高于中度、轻度患者（均P<0.01）。以HBV-DNA载量1× 105 copy/mL为界分为高载量与低载量,HBV-DNA高载量患者PBMC中Caspase-3 mRNA、Caspase-6 mRNA、Caspase-8 mRNA表达量高于HBV-DNA低载量患者（P<0.01）;且3者mRNA与IL-2/IL-10、IFN-γ/IL-4呈负相关（P<0.05）,与HBV-DNA载量呈正相关（P<0.05）。结论 PBMC中凋亡分子（Caspase-3、Caspase-6、Caspase-8）mRNA表达随CHB患者病情加重而升高,并与Th1/Th2失衡及HBV-DNA载量具有相关性,抑制凋亡分子表达可为Th1/Th2失衡的纠正及控制HBV的复制提供新思路。

| Abstract: | Objective To explore the expression level and clinical significance of apoptosis molecules in peripheral blood mononuclear cells （PBMC） of patients with chronic hepatitis B （CHB）. Methods Taking CHB patients diagnosed and treated in the department of gastroenterology of a hospital in Zhengzhou from January 2018 to July 2020 as the research object, comparing the mRNA expression of apoptosis molecules （including Caspase-3, Caspase-6, Caspase-8） in PBMC, T Helper （Th） 1 cytokine levels including interleukin （IL） -2 and interferon-γ （IFN-γ）], and Th2 cytokine levels （including IL-4 and IL-10） among patients with different severity degree. Pearson correlation analysis method was used to analyze the relationship of apoptosis molecules to IL-2 / IL-10 and IFN-γ / IL-4. According to the average expression of apoptotic molecules, the patients were divided into low expression and high expression to compare the hepatitis B virus （HBV）-DNA load, and the relationship between apoptotic molecules and HBV-DNA was analyzed. Results A total of 116 patients with CHB were included in this study, including 83 males, accounting for 71.6%. The age of the patients was 27 - 78 years old, with the largest proportion of 45 - 59 years old, accounting for 50.9%. There were 36, 45 and 35 patients with mild, moderate and severe CHB, accounting for 31.0%, 38.8% and 30.1% respectively. The expression levels of Caspase-3 mRNA, Caspase-6 mRNA, and Caspase-8 mRNA in PBMC of CHB patients with different severity degree were significantly different （all P<0.01）. IL-2, IFN-γ, IL-2/IL-10, and IFN-γ/IL-4 in severe patients were lower than moderate and mild patients, IL-4 and IL-10 were higher than moderate and mild patients （all P<0.01）. The HBV-DNA load was equal to 1×105 copy/mL as the boundary, Caspase-3 mRNA, Caspase-6 mRNA, and Caspase-8 mRNA in PBMC of patients with high HBV-DNA load were higher than those of patients with low HBV-DNA load （P<0.05）. Caspase-3 mRNA, Caspase-6 mRNA, and Caspase-8 mRNA was negatively correlated with IL-2/IL-10 and IFN-γ/IL-4 （P<0.05）, and positively correlated with HBV-DNA load （P<0.05）. Conclusion The expression of apoptotic molecules mRNA （including Caspase-3, Caspase-6, Caspase-8） in PBMC go up with the progression of CHB patients, and it has a correlation with Th1/Th2 imbalance and HBV-DNA load, inhibiting the expression of apoptotic molecules can provide a potential idea for correcting Th1/Th2 imbalance and controlling HBV replication. |
