Aims. Study the effect of Abnormal Savda Munziq (ASMq) ethanol extract on the proliferation, apoptosis, and correlative gene, expression in colon cancer cells (Caco-2) to elucidate the molecular mechanisms responsible for the anticancer property of Abnormal Savda Munziq. Materials and Methods. ASMq ethanol extract was prepared by a professional pharmacist. Caco-2 cells were treated with different concentration of ASMq ethanol extract (0.5-7.5 mg/mL) for different time intervals (48 and 72 h). Antiproliferative effect of ASMq ethanol extract was determined by MTT assay; DNA fragmentation was determined by gel electrophoresis assay; cell cycle analysis was detected by flow cytometer; apoptosis-related gene expression was detected by RT-PCR assay. Results. ASMq ethanol extract possesses an inhibition effect on Caco-2 cells proliferation, induction of cell apoptosis, cell cycle arrest in sub-G1 phase, and downregulation of bcl-2 and upregulation of Bax gene expression. Conclusion. The anticancer mechanism of ASMq ethanol extract may be involved in antiproliferation, induction of apoptosis, cell cycle arrest, and regulation of apoptosis-related gene expression such as bcl-2 and Bax activity pathway.

    • "The viability of the spleen lymphocyte was assessed by MTT (3,4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide) assay, which is based on the reduction of MTT by the mitochondrial dehydrogenase of intact cells to a purple formazan product [5-7,9]. A suspension of spleen cells was diluted to 1 × 107 cell/L; 100 μl of cell suspension was seeded in 96-well plates (Coastar, Corning, NY) with 100 μl RPMI-1640 containing 5 μg/mL ConA, with three wells per sample.

    ABSTRACT: Background Abnormal Savda Munziq (ASMq), a traditional uyghur medicine, has shown anti-tumour properties in vitro. This study attempts to confirm these effects in vivo and measure effects on the immune system. Methods Kunming mice transplanted with Sarcoma 180 cells were treated with ASMq (2–8 g/kg/day) by intra-gastric administration compared to model and cyclophosphamide (20 mg/kg/day). After the 14th day post tumour implant, thymus, liver, spleen and tumours were removed, weighed, and processed for histopathological analysis. Blood samples were also taken for haematological and biochemical analyses including TNF-α , IL-1 β and IL-2. Splenic lymphocyte function was measured with MTT; lymphocyte subpopulations were measured by flow cytometry. Results ASMq treated animals had reduced tumour volume compared to model and increased concentrations of TNF-α, IL-1β and IL-2 compared to untreated and to cyclophosphamide-treated animals. No histopathological alterations were observed. The absence of viable S180 cells and the presence of necrotic cells and granulation tissue were observed in tumour tissue of treated animals. The effect on T lymphocytes was unclear. Conclusions ASMq confirmed in vivo anti-tumour effects observed in vitro, which may be at least in part mediated by increased immune activity.

    ABSTRACT: To investigate the effects of different doses of abnormal Savda Munziq on myocardial ischemia-reperfusion injury (MI/RI) in rats with the abnormal Savda syndrome, 50 abnormal Savda animal models were randomly divided into a control group, a model group, a high-dose group, a middle-dose group, and a low-dose group, with each group containing 10 rats. The enzyme-linked immunosorbent assay was used to detect the serum myocardial enzyme and troponin levels, and hematoxylin and eosin (HE) staining was used to observe changes of the myocardial tissues in the different groups. Results showed that in the Munziq intervention groups, the serum creatine kinase and troponin levels were significantly lower than those in the model group, and the middle-dose group showed the lowest levels. The HE staining of myocardial tissue showed that the myocardial edema and muscle fiber proliferation levels were significantly higher in the Munziq intervention groups than in the model group, and the middle-dose group showed the least cardiac tissue damage. Therefore, intervention with an intermediate Munziq dose could significantly reduce MI/RI in rats with abnormal Savda syndrome.

    ABSTRACT: Objective: To investigate the effects of abnormal Savda Munziq (ASMq) total phenolics combined with cisplatin and docetaxel on the Hela cell growth. Methods: In vivo cultured Hela cells were treated with cisplatin, docetaxel, total phenolics, cisplatin+total phenolics or docetaxel+total phenolics. MTT was performed to assess inhibition of cell proliferation, flow cytometry to detect apoptosis, and semi-quantitative RT-PCR to test for survivin and Bcl-2 expression. Results: The total phenolics, cisplatin and docetaxel had significant inhibitory and apoptosis-promoting effects on Hela cells (P<0.05), with the early apoptotic rates of 12.8±0.70%, 18.9±3.79% and 15.8±3.8)%; the total phenolics, cisplatin and docetaxel significantly decreased the expression of Bcl-2 and survivin (all P<0.01), especially when used in combination. Conclusion: ASMq total phenolics, combined with cisplatin and docetaxel, could promote the apoptosis of Hela cells possibly through reducing the expression of Bcl-2 and survivin.
