Objective To explore the effect of cisapride combined with polyethylene glycol electrolytic solution on preoperative bowel preparation for patients receiving colorectal cancer operation. Methods One hundred and fifty-two patients received colorectal cancer opera-tion in our hospital from October 2010 to October 2014 were selected. Those who were treated with cisapride combined with polyethylene gly-col electrolytic solution for bowel preparation before operation were assigned to oberservation group(n=83),those who were treated with poly-ethylene glycol electrolytic solution for bowel preparation before operation were assigned to control group(n=69). The side effect after medi-cation, electrolyte concentration and incidence of incision infection between groups after operation were collected and compared. Results The incidence of nausea and vomiting was 7. 23% in observation group,which was significantly lower than 18. 84% in control group (χ2 =4. 64,P=0. 03). The difference of Na+,K+ and Cl- concentration between groups were not significant (t=1. 83,P=0. 07;t=0. 42,P=0. 68;t=1. 86,P=0. 07). The body temperature,leukocyte count and incidence of incision infection after operation in observation group were significantly lower than those in control group (t=2. 68,P<0. 01;t=3. 29,P<0. 01;χ2 =4. 90,P=0. 03). Conclusion Cisapride com-bined with polyethylene glycol electrolytic solution before operation can significantly decrease the incidence of gastrointestinal side effect after medicaiton and incision infection after operation and it is beneficial to recovery for patients with colorectal cancer operation.

Objective; To evaluate the efficacy of Twin-block appliance in Class Ⅱ division 1 of adolescents. Methods: Several e-lectronic databases (PubMed, The Cochrane library, Embase, CBMdisk, CNKI, VIP)were searched. Abstract that appears to fulfill the initial selection criteria were selected by consensus and original articles were retrieved. Five Chinese journals were hand searched for possible missing articles. Randomized controlled trials(RCTs) that evaluate the efficacy of Twin-block appliance in Class Ⅱ division I adolescents without any surgical intervention or syndromic characteristics were considered. A comparable untreated control group was required to factor out normal growth changes. The quality of included studies was evaluated according to Cochrane Reviewers Handbook 4.2.6 Meta-analysis was performed by using RevMan 5.0.0 software. Results: Four RCTs including 289 patients were identified. The results of our meta-analysis showed a significant increase on SNB angle, Ar-Gn, Nasolabial angle and Labial-mental fold compared with control group(P<0.05). Whereas overjet, overbite, ANB angle and Ls-E had a significant decrease. In addition, SNA angle and Li-E didnt show statistical significant changes(P>0. 05). Conclusion; In Class II division 1 of adolescents, Twin-block appliance can effectively decrease their overjet, overbite, ANB angle, and induce anterior-posterior growth of mandible. The effect on restrain forward growth of the maxilla was unclear. More RCTs are required to evaluate the efficacy of Twin-block appliance.

Objective To evaluate the left ventricular (LV) systolic dyssynchrony after the acute myocardial infarction (AMI) with two-dimensional speckle tracking echocardiography (STE). Methods STE were performed in 65 patients within 72 h of AMI and compared with 60 age- and sex-matched healthy volunteers. The peak longitudinal strain (LS_(peak)) was measured at LV myocardium. LV dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Size of myocardial infarction (MIS)was confirmed by wall-motion score index (WMSI). Results The LS_(peak) and LV ejection fraction (LVEF) were lower, and WMSI and TAS-POST were larger in AMI patients compared with controls. Forty-two patients had developed LV dyssynchrony (64.62%), and there were strong correlation between LV dyssynchrony (TAS-POST) and LS_(peak), LVEF, and WMSI (MIS). MIS was the most independent predictor for systolic dyssynchrony. Conclusion AMI with normal QRS can induce LV dyssynchrony, which is mainly determined by MIS. STE is a reliable technique for accurate evaluation of LV synchrony.
