炎症微环境在影响肝癌发生发展中具有重要作用，基于炎症微环境调控的肝癌防治新策略越来越受到关注。然而由于炎症微环境的复杂性，单一炎症细胞或因子调控难以获得理想疗效。传统中药具有多靶点和多向调节的优势，八宝丹是我国传统中药中一种具有确切疗效的复方抗炎保肝药物。我们前期在大鼠原发性肝癌模型中发现八宝丹对于肝癌的发生和发展具有显著的抑制作用，但具体机制尚不清楚。本课题拟利用大鼠原发肝癌模型，在诱癌的不同阶段给予八宝丹干预，观察八宝丹对肝癌发生发展的影响；通过研究诱癌不同阶段相关炎症细胞和炎症因子的变化，明确八宝丹抑炎的关键作用细胞和因子；再通过体内外实验观察八宝丹对靶细胞功能的影响及炎症因子对正常肝细胞恶性转化及肝癌细胞恶性增殖的影响，阐明八宝丹通过抑制炎症达到抑制肝癌发生发展的具体机制。预期结果有助于我们加深对炎症在肝癌发生发展中作用机制的认识，也为八宝丹更为有效地应用于肝癌治疗提供理论依据。

Inflammatory microenvironment plays an important role in the development of hepatocellular carcinoma (HCC) and the microenvironment modification is expected to become a new strategy for the prevention and therapy of HCC. However, due to the complicated inflammatory microenvironment, the strategy by regulating single inflammatory cell or factor is hard to get ideal result for inhibiting HCC development. Chinese traditional medicine has the advantages of multiple targets and multidirectional adjustment. Babao Dan (BBD), as a Chinese traditional medicine, is known as the potential of anti-inflammation and liver function protection. Our previous study demonstrated that BBD could inhibit the incidence and development of HCC in rat. However, the underlying mechanism of is still unknown.

Babao Dan (BBD), as a Chinese traditional medicine, is known as the potential of anti-inflammation and liver function protection. Our previous study demonstrated that BBD could inhibit the incidence and development of HCC in rat. However, the underlying mechanism is still unknown. Based on the HCC animal model, the effect of BBD on the development of HCC will be observed by administrating BBD at different time stage of HCC. Then, we will screen out the key inflammatory cells and factors by analyzing the profile of inflammatory cells and factors in different stage of HCC with or without BBD administration. Furthermore, we will clarify the mechanism of BBD in inhibiting the development of HCC by exploring the role of BBD in inhibiting relative inflammatory cell and in inhibiting malignant transformation of normal hepatocytes and malignant proliferation of HCC cells induced by relative inflammatory cytokines. The results will not only help us to understand the underlying mechanism of inflammation in the development of HCC, but also provide a new direction and research basis for BBD using in HCC therapy.
