慢性肝炎,是由病毒、药物、酒精或其它原因引起的肝脏炎症。其组织学及生物化学的异常表征持续时间长而且无明显好转,但不少作者认为病程超过6个月者称为慢性。单纯以病程来区分,也不完全妥当,临床实践证明有的患者可以不出现明显的肝炎病史,或有的病例在6个月内死亡。近10余年来根据病理特征将慢性肝炎分为两类。 Chronic hepatitis is liver inflammation caused by viruses, drugs, alcohol or other causes. The histological and biochemical abnormalities lasted for a long time and no significant improvement, but many authors believe that the duration of more than 6 months are called chronic. Purely to distinguish between the course of disease is not entirely appropriate, clinical practice has proved that some patients may not have a clear history of hepatitis, or some cases died within 6 months. Over the past 10 years based on pathological features of chronic hepatitis will be divided into two categories.
