Proliferation-inhibiting and apoptosis-inducing effects of ursolic acid and oleanolic acid on multi-drug resistance cancer cells in vitro / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the proliferation-inhibiting and apoptosis-inducing effects of ursolic acid (UA) and oleanolic acid (OA) on multi-drug resistance (MDR) cancer cells in vitro.</p><p><b>METHODS</b>UA and OA in different concentrations (0-100 μmol/L) were added separately to cultures of different cancer cell lines, including the human colon cancer cell lines SW480 and SW620, human acute myelocytic leukemia cancer cell lines HL60 and HL60/ADR, human chronic myelogenous leukemia cell lines K562 and K562/ADR, and the human breast cancer cell lines MCF-7 and MCF-7/ADR. Effects of UA and OA on cell proliferation were detected by 3-(4,5-dimethyl-2-thiazole)-2-5-biphenly-tetrazole bromide (MTT) method and effects on cell apoptosis were tested by flow cytometry (FCM) and Western blot at 24, 48, and 72 h after treatment.</p><p><b>RESULTS</b>Both UA and OA showed significant inhibition on parent and MDR cell lines in a time- and concentration-dependent manner; the drug-resistant multiple of them on K562 and K562/ADR as well as on HL60 and HL60/ADR was 1; the effects of UA were better than those of OA in inhibiting cell growth of solid colonic cancer and breast cancer. After SW480 cells were treated by UA at the concentrations of 0-40 μmol/L for 48 h, FCM showed that annexin V (AV) positive cells and hypodiploid peak ratio increased along with the increase in the drug's concentrations; and Western blot found that expressions of Bcl-2, Bcl-xL and survivin decreased in a concentration-dependent manner.</p><p><b>CONCLUSIONS</b>Both UA and OA have antitumor effects on cancer cells with MDR, and the optimal effect is shown by UA on colonic cancer cells. Also, UA shows cell apoptosis-inducing effect on SW480, possibly by way of down-regulating the expressions of apoptosis antagonistic proteins, Bcl-2, Bcl-xL, and survivin.</p>

Clinical observation on treatment of post-craniocerebral traumatic mental disorder by integrative medicine / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the clinical efficacy of integrative medical therapy in treating post-craniocerebral traumatic mental disorder (PCT-MD).</p><p><b>METHODS</b>Sixty patients with confirmed diagnosis of PCT-MD were randomly assigned to the treated group and the control group equally. All were treated by conventional comprehensive Western medicine, but to patients in the treated group, modified Xufu Zhuyu Decoction (XFZY) was additionally given and the therapeutic course for both groups was 20 days. Changes in mental symptoms were observed and recorded on the 10th and 20th day and clinical efficacy as well as cranial CT image was estimated after termination of the treatment.</p><p><b>RESULTS</b>The clinical effective rate in the treated group and the control group was 96.67% and 83.30% respectively. Comparison between them showed significant difference (P<0.05). Significant differences were also shown in the comparisons between the two groups in improving mental symptoms, either on the 10th or on the 20th day (P<0.05 and P<0.01 respectively), and in post-treatment cranial CT image (P<0.05).</p><p><b>CONCLUSION</b>Better efficacy could be obtained by integrative medical therapy in treating PCT-MD.</p>

Experimental study on treating hyperlipidemic fatty liver with Taizhi'an capsule / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the effects of Taizhi'an capsule in treatment of hyperlipidemic fatty liver.</p><p><b>METHOD</b>The model rats were induced by feeding high caloric diet for 8 weeks, then fifty rats were randomly divided into five groups, and each group had ten rats, the Taizhi'an groups (high dose 1 000 mg x kg(-1), middle dose 500 mg x kg(-1), low dose 250 mg x kg(-1)), the Yishanfu group and the model group. Liver index (liver weight/body weight), liver function, blood lipid, liver lipid, the content of MDA and SOD in liver were assayed after therapy, and observe Pathologic changes in rats liver.</p><p><b>RESULT</b>Liver index, blood lipid, liver lipid, liver function increased significantly (P < 0.001) in model rats, and the content of SOD in liver decreased significantly (P < 0.05), Liver histology expressed mild to moderate fat denaturation; After being treated with high and middle dose of Taizhi'an capsule for six weeks, blood lipid, liver function decreased significantly (P < 0.001), and liver lipid decreased significantly (P < 0.001, P <0.05), the content of SOD in liver increased significantly (P < 0.05), meanwhile liver histology was closed to normal.</p><p><b>CONCLUSION</b>Taizhian capsule is effective in the treatment of hyperlipidemic induced fatty liver.</p>
