Objective: To explore the mechanism of herb-partitioned moxibustion for ulcerative colitis (UC) through observing the colonic mucosal histopathological changes and the expression of nuclear factor kappaB (NF-kB) and peroxisome proliferators-activated receptorγ (PPARγ) mRNA of UC rats. ＜br> Methods: Male SD rats were randomly divided into a normal group and a model group. UC model was established by general immunological plus local irritation method. After model identification, rats in the model group were randomly divided into a model group, a herb-partitioned moxibustion (HPM) group and a Western medicine (Salicylazosulfapyridine, SASP) group. Rats in the HPM group received treatment at bilateral Tianshu (ST 25) and Dachangshu (BL 25), two cones for each point, once a day for 7 d. SASP group rats were gavaged with SASP. The pathological scores were evaluated according to hematoxylin-eosin (HE) staining of colonic tissues. We used light microscopy to observe degree of colonic mucosal damage and the quantitative polymerase chain reaction (QPCR) to detect the expression of NF-κBp65 and PPARγ in colorectal mucosa. ＜br> Results: Compared with the normal group, histopathological scores were significantly higher in the model group (P＜0.05); compared with the model group, the scores were decreased significantly in the HPM group and the SASP group. Compared with the normal group, NF-κBp65 mRNA expression was increased with statistical significance in the model group (P＜0.05); compared with the model group, NF-κBp65 mRNA expressions were decreased significantly in the HPM group and the SASP group. Compared with the normal group, PPARγ mRNA expression was increased significantly in the model group (P＜0.05); compared with the model group, PPARγ mRNA expressions were decreased significantly in the HPM group and the SASP group. ＜br> Conclusion: HPM could improve the mucosa damage of UC rats, which is possibly through down-regulating NF-κBp65 to achieve anti-inflammatory effect. Whether decreasing the PPARγ mRNA is possibly involved in preventing precancerosis will need further study.

Objective: To evaluate the short-term effect of thrombus aspiration catheters combining tiroifban medication for myocardial tissue reperfusion recovery in patients with acute ST-elevation myocardial infarction (STEMI).
Methods: A total of 105 STEMI patients with percutaneous coronary intervention (PCI) in our hospital from 2011-05 to 2013-05 were studied, there were 73 male and 32 female with the mean age of (58.39 ± 10.37) years. The patients were randomly divided into 2 groups, Group A, the patients received thrombus aspiration catheters with intravenous tiroifban, n=53 and Group B, the patients received tiroifban and PCI, n=52. The basic clinical features, myocardial tissue perfusion level, major adverse cardiovascular events (MACE) at post operative and in-hospital period were recorded, the cardiac function was examined by echocardiography at 6 months after PCI in both groups.
Results: The basic clinical features were similar between 2 groups. The thrombolysis in myocardial infarction trial (TIMI) 3 lfow rate was higher in Group A than that in Group B (92.45% vs 55.77%), P=0.000. TIMI 2 and TIMI 0~1 lfow rates were lower in Group A than that in Group B (7.55%vs 26.92%), P=0.008 and (0%vs 17.31%), P=0.002. The adjusted TIMI frame was lower in Group A (27.26±5.50) vs (38.98±5.42), P<0.001. The echocardiography at 6 months after PCI indicated that Group A had higher LVEF than that in Group B (0.55±0.06) vs (0.47±0.06), P<0.001;lower left ventricular end diastolic diameter (50.77±5.45) vs (54.76±5.34), P<0.001;less angina and target vessel revascularization (16.98%vs 40.38%), P=0.008 and (9.43%vs 17.31%), P=0.008. The incidence of MI, acute heart failure, cardiac death and non-target vessel revascularization were similar between 2 groups, P>0.05.
Conclusion:Thrombus aspiration catheters combining tiroifban medication may obviously improve the myocardial tissue reperfusion and the short-term cardiac function in STEMI patients after PCI, it could reduce the incidence of no-relfow without increasing MACE.

Objective: To explore the clinical response on cardiac resynchronization therapy (CRT) in patients of chronic heart failure (CHF) with different QRS wave morphology. Methods: A total of 52 CHF patients received CRT in our hospital and the Seventh People's Hospital of Zhengzhou City from 2010-03 to 2013-07 were retrospectively studied. The patients were divided into 3 groups: True-complete left bundle branch block (t-CLBBB) group,n=20, Classic LBBB (CLBBB) group,n=15 and IVCD group,n=17. The general clinical condition, the indexes of echocardiography at 6 months of follow-up study including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), NYHA classiifcation and 6-MWT were examined and compared among different groups. Results: In general clinical condition, the ratio of non-ischemic heart disease patients in t-CLBBB group was higher than those in CLBBB group and IVCD group, allP<0.05. By 6 months follow-up study, LVEDD in t-CLBBB group (62.6 ± 8.9) mm was lower than those in CLBBB group (70.0 ± 8.9) mm and IVCD group (72.8 ± 8.0) mm, LVEF was higher in t-CLBBB group (38.5 ± 6.2) % than those in CLBBB group (31.7 ± 6.7) % and IVCD group (30.1 ± 6.7) %. NYHA classiifcation in t-CLBBB group (2.00 ± 0.45) grade was lower than those in CLBBB group (2.73 ± 0.80) grade and IVCD group (3.12 ± 0.78) grade . 6-MWT in t-CLBBB group (302.0 ± 57.9) m was longer than those in CLBBB group (257.3 ± 59.0) m and IVCD group (220.2 ± 57.9) m, allP<0.05. Conclusion: CRT is an effective method for treating CHD patients, different QRS morphology may have different response, the patients with t-CLBBB would make better response.
