OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.

METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.

RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).

CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.

Objective: To quantitatively study the incidental extra-cardiac ifndings (ECFs) by coronary computed tomography angiography (CCTA) in patients with suspected coronary artery disease (CAD) in order to better recognize those lesions in clinical practice.
Methods: A total of 1169 suspected CAD patients received CCTA in our hospital from 2011-06 to 2013-03 and 1030 patients were enrolled in this study. There were 589 in-patients, 441 out-patients and 549 patients≥60 years of age,481 patients < 60 years of age. 3 physicians evaluated the incidental ECFs in the full ifeld of view (FOV) in different window level and window width for lung, mediastinum, thorax and upper abdominal areas. Clinical relevance of ECFs were classiifed by corresponding scores. Score 1, the patients with severe lesion need immediate treatment, score 2, the lesion with clinical and prognostic signiifcance and score 3, the ifnding without clinical signiifcance.
Results: There were 197/1030 (19.1%) patients having 224 ECFs and 27 (2.6%) patients having 2 ECFs; 90/1030 (8.7%) patients having 106 signiifcant lesions including 3 (0.3%) of lung cancer and 8 (0.8%) of pulmonary embolism; 107 patients with 118 lesions without signiifcance. ECFs were found in 114/589 (19.4%) in-patients and in 83/441 (18.8%) out-patients, P>0.05; 76/481 (15.8%) of patients < 60 years of age and 121/549 (22.0%) of patients≥60 years,P<0.05.
Conclusion: Unexpected ECFs detection rate was 19.1% in patients undergoing CCTA without further radiation exposure by reconstruction with the full FOV setting, and 8.7% of ECFs had clinical signiifcance. Radiologists should routinely analyze the extra-cardiac organs in CCTA.

Purpose To explore the correlation between fetal cardiac function and interventricular septal thickness in fetuses of gestational diabetes mellitus (GDM) mothers. Materials and Methods Thirty-nine GDM mothers were involved in the study and divided into group MH (fetuses of GDM mothers with interventricular septal hypertrophy) and group NMH (fetuses of GDM mothers with normal interventricular septal thickness). Ultrasonic cardiogram was performed for both groups to assess such variables as interventricular septum thickness at end diastole (IVSd), left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), right ventricular fraction shortening (RVFS), the ratio of E and A of mitral flow (E/AMV), the ratio of E and A of tricuspid flow (E/ATV), peak velocity of aortic valve (VPAO), peak velocity of pulmonary valve (VPPA) and myocardial performance index (MPI). The results were further compared with those of control group. Results The VPAO, VPPA, LVEF and LVFS in group NMH were significantly higher than those in control group (P<0.05). The VPAO, VPPA, LVEF, LVFS and RVFS in group MH were significantly higher than those in control group whilst the E/AMV and E/ATV significantly lower than those in control group (P<0.05). The LVEF, LVFS and RVFS in group MH were significantly higher than those in group NMH whilst the E/AMV and E/ATV significantly lower (P<0.05). MPI in group MH was significantly higher than that in group NMH (P<0.05), whilst both were significantly higher than that in control group (P<0.05). The LVEF, LVFS, RVFS, VPAO and VPPA were positively correlated with IVSd (r=0.48, 0.51, 0.45, 0.30, 0.30;P<0.05). Conclusion Cardiac function in fetuses of GDM mothers may be associated with interventricular septal thickness.
