慢性乙型病毒性肝炎（慢乙肝）已成为全球面临的主要公共卫生问题之一，为社会和个人带来了一定程度的负担。本病中医病因可归纳为外感湿热疫毒，病机为湿、痰、瘀、毒相互搏结、壅滞机体，日久耗伤气血、阴阳无法顺接，最终导致脏腑功能的衰竭。本研究团队根据慢乙肝临床症候特点，基于“疫毒致病”理论，根据疾病不同阶段的症候特征，采用三期解毒法辨证治疗慢乙肝，取得了较好的临床疗效，可为中医药防治慢乙肝、改善患者预后提供理论指导。

Chronic viral hepatitis B has become one of the major public health problems facing the world， bringing great pressure and economic burden to the society. The cause of this disease in Chinese medicine is mainly exogenous dampness-heat and epidemiological toxins， and the pathogenesis is that dampness， phlegm， stasis， and toxins fight with each other and congest the organism， which depletes qi and blood， and yin and yang can not be connected with each other， and ultimately leads to the failure of the functions of organs and bowels. According to the clinical symptoms of chronic hepatitis B， based on the theory of "disease caused by epidemics and toxins"， the team adopted the three-phase detoxification method to treat chronic hepatitis B based on the symptomatic characteristics of different stages of the disease， which achieved good clinical efficacy and provided theoretical guidance for the treatment of chronic hepatitis B by Traditional Chinese Medicine.
