Objective To investigate the effects of Morusin on cell line proliferation, cell cycle and cell apoptosis of colorectal cancer HCT116 cell;To discuss its mechanism. Methods HCT116 cells were treated with different concentrations of Morusin for 72 h. Cell proliferation was detected by CCK-8 assay, and cell growth inhibition rate and IC50 value were calculated. HCT116 cells were treated with 25.4, 50.8 μmol/L Morusin for 24 h, 48 h and 72 h. Cell morphology was observed under the microscope, and cell proliferation was detected by CCK-8 assay. After HCT116 cell line was treated with 25.4μmol/L Morusin for 24 h, cell cycle phase distribution was detected by flow cytometry and the cell apoptosis was detected by TUNEL assay under the fluorescence microscope. Post-intervention protein expressions were detected by Western Blot. Results The inhibitory effects of Morusin on the proliferation of HCT116 cell line was concentration/time dependent and IC50 value at 72 h was 25.4μmol/L;Morusin induced the cell cycle arrest at G0/G1 phase and G2/M phase, but there was no induction of cell apoptosis;Morusin significantly decreased the expression ofβ-catenin and its target c-Myc, and downregulated the expressions of cyclinD1 and cyclinB1, which were involved in cell cycle regulation. Conclusion Morusin can inhibit HCT116 cell cycle and the proliferation of colorectal cancer cells. Its mechanism might be realized by suppressing the activity ofβ-catenin pathway and reducing the protein expressions of cyclinD1 and cyclinB1.

Objective To investigate the effects of Xiaotan Sanjie Recipe (XTSJR) on the proliferation and apoptosis of colorectal cancer cell;To study its relevant mechanism. Methods The original XTSJR aqueous solution was lyophilized, weighted, and dissolved in cell culture and stored. HCT116 cell line was treated with different concentrations of XTSJR for 72 h, and the cell proliferation was detected by CCK-8 assay. XTSJR treated HCT116 cell line with the concentration of 0.94 mg/mL and 1.88 mg/mL for 24 h, 48 h, 72 h, and the cell proliferation was detected by CCK-8 assay. HCT116 cell line was treated with different concentrations (0.24, 0.47, 0.94, 1.88 mg/mL) of XTSJR for 72 h. The cell apoptosis was detected by TUNEL assay under the fluorescence microscope, and the post-intervention expression of Caspase3 protein was detected by Western blot. Results The inhibitory effects of XTSJR on the proliferation of HCT116 cell line was concentration-time dependent. The IC50 value at 72 h-time point was 0.94 mg/mL. Medicine concentration and the treated time have interactive contribution to the inhibitory effect. XTSJR induced the cell apoptosis. The apoptosis rate increased with the increasing medicine concentration. There was statistically significant difference compared with the control group ( P<0.01). After treatment the expression of Pro-Caspase3 decreased, while the expression Cleaved Caspase3 protein increased. Conclusion XTSJR inhibits the proliferation of HCT116 cell line and induce apoptosis. Its mechanism might be related to the activity of Caspase3 protein.

Abstract: Based on years of ancient literature research and clinical experience, Professor Pin-kang Wei developed the phlegm theory of gastric cancer. In light of the properties of gastric cancer and the method of differentiating syndromes within the traditional Chinese medicine (TCM) paradigm, it is believed that gastric cancer is closely related with phlegm. Much ancient literature regarding the relationship between phlegm and gastric cancer was reviewed to explain the rationale and academic inheritance of the phlegm theory. In this theory, gastric cancer is regarded as a form of phlegm stagnation and consists of phlegm core, phlegm collateral and phlegm contamination. In order to explain the mechanism of development, recurrence and metastasis of gastric cancer, phlegm contamination is regarded as the most fundamental cause and pathogenesis of gastric cancer. The therapy of resolving phlegm and dispersing nodules is suggested for the fundamental treatment of gastric cancer.

Professor Wei Pin-kang developed phlegm theory for gastric cancer. He adopted the therapy of resolving phlegm and dispersing nodules as the fundamental therapy for gastric cancer. As the symptoms may vary due to the changes of etiology and pathogenesis at different stages of gastric cancer, he further formulated eight therapies based on the fundamental therapy, namely, resolving phlegm and regulating stomach, resolving phlegm and removing stagnancy, resolving phlegm and clearing heat toxin, resolving phlegm and relieving qi depression, resolving phlegm and dredging collaterals, resolving phlegm and removing blood stasis, resolving phlegm and promoting diuresis, and resolving phlegm to soften abdominal mass. These therapies showed satisfactory effects following the principle of simultaneous treatment of disease and symptoms.
