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 investigate the operation key points and therapeutic effect using the pressure cooker technique (PCT)for embolization of the dural arteriovenous fistula (DAVF)at the petrous apex region. Methods The clinical data of 4 patients with DAVF at the petrous apex region admitted to the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University from October 2015 to February 2016 were analyzed retrospectively. The PCT technique was used to conduct embolization therapy. Results DSA confirmed that 4 patients had DAVF at the petrous apex region with the multi-branch artery blood supply and they were drained via the superior petrosal veins. The patients were embolized by using PCT. DSA confirmed that they were embolized completely after procedure. They were followed up at 3months after surgery and their symptoms were improved. Conclusion For DAVF at the petrous apex region with the multi-branch artery blood supply,the preliminary experience shows that PCT technique may improve the efficiency of embolization,thereby obtaining anatomical cure.

Objective To assess the value of two-dimensional speckle tracking echocardiography (2D-STE) of predicting the acute response to cardiac resynchronization therapy (CRT) in patients with congestive heart failure. Methods Twenty-four patients with congestive heart failure scheduled for CRT were included. 2D-STE was performed within 7 days of implantation with device ON and OFF. Left ventricular (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 (T_(AS-POST)) with 2D-STE. Acute hemodynamic response was measured as LVdp/dt, and percentage change in LVdp/dt was used to classify responders (Δdp/dt%>25%) and nonresponders (Δdp/dt%≤25%). Results Fifteen patients (62.50%) were classified as acute responders. Compared with nonresponders, the responders demonstrated significant increase of LV ejection fraction and reduction of TAS-POST after CRT-ON. T_(AS-POST)was the only determinants of Δdp/dt%>25%. T_(AS-POST)≥130 ms prognosticated acute response to CRT with sensitivity of 86.24% and specificity of 70.38%. Conclusion CRT can immediately increase the LV systolic function and synchrony. 2D-STE is highly predictive for acute response to CRT.
