ABSTRACT
Ulcerative colitis (UC) is associated with intestinal immune imbalance and inflammatory response. Because dehydrolovastatin (DLVT), a derivative of lovastatin, has been recently shown to inhibit inflammation and relieve immune arthritis induced by chemical stimuli, we studied its effect and possible mechanism on UC induced by dextran sulfate sodium. The BALB/c mice were classified into six groups: normal control group, model group, DLVT high dose group, DLVT low dose group, salazosulfapyridine (SASP) group and lovastatin (LVT) group. The disease activity indices of UC and pathological changes were investigated. The myeloperoxidase (MPO) activity in colon tissue and inflammatory factors such as IL-6, IL-10, IL-17, and TNF-α in the serum were analyzed by ELISA, while the expression of NF-κB p65 protein in colon tissue was detected by immunohistochemistry and western blot. DLVT relieved the disease activity indices and pathological damage of the UC mice. Furthermore, DLVT significantly decreased MPO activity and improved the imbalance of inflammatory cytokines through inhibiting the expression of NF-κB p65. Meanwhile, the positive drug of SASP has a similar effect to DLVT, but the effect of DLVT in both decreasing IL-17, TNF-α, and increasing IL-10 was significantly stronger than that of SASP. These results suggest that DLVT may ameliorates the symptoms of UC.

ABSTRACT
AIM To investigate the role of ginkgolide B on the ventricular wall motion and systolic function in acute myocardial infarction (AMI) patients after their revascularization.METHODS A total of 80 cases of AMI patients who underwent revascularization were divided into control group and ginkgolide B treatment group,with 40 patients per group.The two groups of patients both treated basically with routine western medicine were dosed with either placebo or ginkgolide B for 3 months.The cardiac function,normal myocardial percentages,ventricular wall motion,longitudinal peak systolic strain (LPSS) and rate (LPSSR) were evaluated by dobutamine stress echocardiography and these indexes were compared.RESULTS Compared to the control group,left ventricular ejection fraction (LVEF) (66.06 ± 8.39 vs.60.45 ± 13.35,P ＜0.05) and normal myocardial percentages (86.88 ±8.76 vs.79.84 ± 12.25,P ＜0.01) were significantly improved at the 2nd week in ginkgolide B treatment group,but no significant difference on ventricular wall motion was observed'between the two groups (P ＞ 0.05).For the patients with anterior wall AMI,the minus LPSS and LPSSR at basal,middle and apex segment were significantly improved at the 2nd week in ginkgolide B treatment group compared to the control group (P ＜ 0.05,P ＜ 0.01).Moreover,LPSS at apex segment was significantly improved at the 3rd month in ginkgolide B treatment group compared to the control group (P ＜ 0.05).For the patients with inferior wall AMI,minus LPSS at basal and apex segment were significantly improved at the 2nd week and the 3rd month in ginkgolide B treatment group compared to the control group (P ＜ 0.05),whereas minus LPSSR at basal and middle segment at the 2 nd week and basal segment at the 3rd month were significantly improved in ginkgolide B treatment group compared to the control group (P ＜0.05).CONCLUSION Revascularized AMI patients treated with ginkgolide B can expect an improved ventricular wall motion.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the analgesic effects of Nourishing yin and Unblocking meridians Receipe (NUR) combined with opioid analgesics in managing cancer pain.</p><p><b>METHODS</b>All the patients enrolled were differentiated as of yin deficiency and meridian blocked syndrome type of TCM. Forty-one of them in the treated group were treated with NUR combined with opioid analgesics, while 43 of them in the control group were given opioid analgesics alone with successive 14 days as one treatment course for both groups.</p><p><b>RESULTS</b>The indexes of the treated group were superior to those in the control group as to the degree of pain-relieving, the therapeutic effect of analgesia, the occurrence frequency of cancer pain every day and its duration each time, the analgesic initial time, and the quality of life.</p><p><b>CONCLUSION</b>NUR combined with opioid analgesics in cancer pain management was more effective than opioid analgesics alone.</p>
