Abstract: Objective To observe the inhibitory effects of Typhonium Giganteum soft capsules on tumor growth in Hep-2 tumor-bearing nude mice and its effects on the expression of tumor suppressor p53 gene; To discuss its mechanism of action.Methods Human liver cancer Hep-2 cell suspension back subcutaneous vaccination was conducted to prepare tumor models. BALB/c nude mice were randomly divided into model group, cisplatinum group, and TCM high-, medium-, and low-dose groups. Each group was given relevant medicine for gavage, once a day for 21 days. Growth changes of tumor volume were monitored; HE staining was used to observe pathological changes of tumor tissues; RT-PCR was used to detect the expression of p53 gene in tumor tissue of Hep-2 nude mice.Results Compared with the model group, all medication groups could inhibit the tumor growth, and the anti-tumor rates were 55.1%, 42.8%, 30.1%, and 79.5%, respectively; the expression of p53 gene increased; pathological observation results showed that the number and the volume of tumor cells increased, with cytoplasm rarefaction and nucleus anachromasis. All medication groups had karyopyknosis, slight staining, and decreasing blood capillary and focal necrosis in varying degrees.ConclusionTyphonium Giganteum soft capsules can inhibit the growth of human liver cancer, and its mechanism may be associated with the up-regulating expression of p53 gene leading to apoptosis.
