ABSTRACT
Hepatic fibrosis is a common feature of almost all chronic liver diseases. Formation of new vessels (angiogenesis) is a process strictly related to the progressive fibrogenesis which leads to cirrhosis and liver cancer. This review mainly concerns the relationship between angiogenesis and hepatic fibrosis, by considering the mechanism of angiogenesis, cells in angiogenesis, anti-angiogenic and Chinese medicine therapies.

OBJECTIVE: To explore the effect of Jianpi Tongluo Jiedu Recipe (JTJR) on protein expression levels of COX-2, NF-kappaBp65, Bcl-2, and Bax, mRNA expression levels of COX-2 and Bcl-2, and the apoptotic index (Al) in gastric mucosa of patients with precancerous lesions of gastric cancer (PL-GC). METHODS: Totally 65 PLGC patients were recruited and treated by JTJR (modified by syndrome typing), one dose per day for six successive months. Protein expression levels of COX-2, NF-KBp65, Bcl-2, and Bax were detected in 65 patients using immunohistochemical (IHC) assay before and after treatment. mRNA expression levels of COX-2 and Bcl-2 were detected in 54 patients using reverse transcription-polymerase chain reaction (RT-PCR). Meanwhile, changes of Al was detected in 65 patients using TdT-mediated dUTP-biotin nick end labeling (TUNEL) fluorescence method. RESULTS: After treatment with JTJR, positive protein expression levels of COX-2, NF-KBp65, and Bcl-2 were obviously decreased in the gastric mucosa of PLGC patients (P <0.01), but Bax positive protein expression was found to be higher (P < 0.05). At the same time mRNA expression levels of COX-2 and Bcl-2 were significantly lower after treatment than before treatment (P < 0.05, P < 0.01); Al also increased after treatment (P < 0.05). CONCLUSION: JTJR could promote apoptosis possibly via NF-kappaBp65/COX-2, COX-2/Bcl-2, and NF-kappaBp65/Bcl-2 signaling pathways, thereby affecting PLGC patients.

Determination of treatment based in pathogenesis obtained through differentiation of symptoms and signs is the characteristic of traditional Chinese medicines' treatment on chronic hepatitis B. There are important effects and special superiorities for traditional Chinese medicines on resisting hepatic fibrosis, improving liver function, protecting liver cells and relieveing the symptoms. The therapeutic effects about the only traditional Chinese medicine and traditional Chinese medicine added western medicine compared with the only western medicine was reviewed in order to explain the traditional Chinese medicine' s therapeutic superiorities.
