Abstract: Objective To investigate the correlation between spleen deficiency syndrome in colorectal carcinoma and bcl-2 gene expression, and observe the regulatory effect of Jianpikangfu decoction. Methods Forty-five advanced colorectal carcinoma patients with spleen deficiency were randomized into Jianpikangfu decoction treatment group with also symptomatic treatment with western medicine and control group in which the patierts were given expactant treatment with western medicine. The activity of salivary amylase and bcl-2 expression in the tumor tissues were detected before and after the treatment. Results Jianpikangfu decoction in combination with western medicine treatment produced more obvious inhibition of reduction in salivary amylase activity than exclusive western medicine treatment (t=7.822, P<0.01), and significantly lowered the positivity rate of bcl-2 expression (χ²=4.286, P<0.05) in the tumor tissues, which, however, displayed no obvious changes in response to exclusive western medicine treatment. Conclusion Jianpikangfu decoction can inhibit the decrease in salivary amylase activity and regulate bcl-2 gene expression in colorectal carcinoma patients with spleen deficiency syndrome.
