RESUMO
OBJECTIVE: To evaluate the efficacy of Qinggan Granule (QGG) and Bushen Granule (BSG) in treating chronic hepatitis C (CHC) from blood donors clinically, biochemically and pathologically as well as to explore the therapeutical principle and methods of TCM. METHODS: Sixty-six patients with CHC were divided into three groups, the 36 patients in the QGG group treated with QGG, the 18 patients in the BSG group treated with BSG and the 12 patients in the control group untreated. The dose of QGG and BSG given was 30 g each time, three times per day for 6 consecutive months. Clinical and serum biochemical parameters as well as pathological change of liver biopsy before and after treatment were observed dynamically and compared. RESULTS: After treatment, in the two treated group, clinical symptoms were improved significantly, alanine transaminase (ALT) and aspartate aminotransferase (AST) reduced markedly. Moreover, QGG showed the effects of increasing albumin and lowering alkaline phosphatase (ALP). On the contrary, ALT still remained as before but AST further increased in the control group. Pathological examination showed that the inflammatory grade (IG) decreased in 42.2% and fibrotic stage (FS) decreased 21.2% of the patients in the QGG group, but no significant changes of the two indexes occurred in the BSG group, while in the control group, IG unchanged and FS increased in 3 cases. Chevallier's semi-quantity system analysis showed significant decrease of both scores in the QGG group (P < 0.05), only decrease of IG in the BSG group, and slight raise of IG and significant increase of FS (P < 0.05) in the control group. CONCLUSION: Condition of chronic hepatitis C patient would deteriorate progressively if not treated in time, especially the development of fibrosis. QGG and BSG could improve the clinical symptoms significantly, lower ALT and AST, eliminate inflammatory damage in the liver, slow down or reverse liver fibrosis process with stable long-term effect. Though most of the patients present a Syndrome of Liver-Kidney Yin-deficiency, the effect of QGG is superior to that of BSG, suggesting that the treatment of CHC should mainly be clearing principle, and method of clearing Liver and eliminating Dampness may be more suitable for them.
