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 efficacy and safety of laparoscopic radiofrequency ablation (RFA) therapy for hepatocellular carcinoma.Methods Clinical data of 78 hepatocellular carcinoma patients undergoing laparoscopic radiofrequency in Beijing China-Japan Friendship Hospital from May.2008 to July.2010 were reviewed retrospectively.Age ranged from 31 to 87 years,41 were male and 37 were female.Intraoperative ultrasound-guided needle biopsy was performed and diagnosis of hepatocellular carcinoma was established in all cases before RFA was carried out.Data analysis was performed using software SPSS or OriginPro7.Necrosis,local recurrence of the tumor and the cumulative survival rate were analyzed by Kaplan-Meier test and x2 test.Results The median follow-up time was 16 months after RFA treatment.Tumor size,proximity to intrahepatic vessels and combination with TACE were factors that influence local recurrence.The complete ablation (CA) rate was remarkably higher in tumors ＜ 3 cm than in tumors ＞ 3 -5 cm (90.5％ vs 71.4％,x2 =4.291,P =0.038 ).Tumors adjacent to major vessels had a significantly lower CA rate as compared with those not adjacent to them (63.6％ vs 91.9％,x2 =6.351,P =0.012).The CA rate were 88.9％ in the TACE ± RFA group and 75.0％ in the RFA group ( x2 =1.567,P =0.211 ).The mean overall survival were 48.7 ± 2.4 months,the cumulative survival rate was 86.1％ at 1 year、76.9％ at 2 years、60.3％ at 3 years、51.8％ at4 years and 33.1％ at 5 years.Conclusions Laparoscopic RFA is safe,mini-invasive and effective for unresectable hepatic carcinoma with a favorable long term survival.

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.

Objective To investigate the therapeutic effect of autologous stem cell transplantation research for patients with cerebral hemorrhage sequelae under the stereotactic.Methods One hundred patients with cerebral hemorrhage from Jan.2011 to Sep.2013 in our hospital were selected and randomly divided into the experimental group (n =50) and the control group (n =50).The patients of experimental group were given autologous stem cell transplantation under the stereotactic in 6 months after cerebral hemorrhage,while the patients in control group were just given traditional treatment.At 6,7 and 12 months after cerebral hemorrhage,rate with neural function defect scale and functional independence measure(FIM) scores of the two groups were compared.Results FIM scores in the experimental group was 102.08 ± 8.28,significant higher than that in control group(95.28±8.75,P＜0.05).Functional independence measure scores in the experimental group at 7 months after cerebral hemorrhage was 13.12±4.00,significant lower than that in control group(20.40±4.33,P ＜0.05).While,there was no statistical difference at 6 months and 12 months after cerebral hemorrhage between the two groups(P＞0.05).Conclusion The therapeutic of autologous stem cell transplantation on patients with cerebral hemorrhage sequelae under the stereotactic is benefit at short term,but the long term therapy effective still needs further study.

Objective To explore diagnostic value of MR perfusion weighted imaging(PWI)on complications and tumor recurrence in hypopharyngeal and laryngeal cancer after operation and radiotherapy. Methods MR PWI was performed in 31 patients with hypopharyngeal and laryngeal cancer who suffer from tumor recurrence, granulation or infection after operation and radiotherapy. Blood flow (BF), blood volume(BV), mean transit time(MTT) and time to peak (TTP) values were measured in the lesions. Analysis of variance and pair-wise comparison of q test were used for statistical analysis. Results Eleven cases with tumor recurrence,11 case with granulation tissues, 9 cases with infection were confirmed by pathological examinations. Average BF, BV, MTT and TTP values of recurrent tumors were (145.1 ± 29.3)ml · 100 g-1 · min-1,(14.2 ± 3.2)ml · 100 g-1,(5.4 ± 0.6)s,(13.7 ± 1.3)s respectively;Average BF, BV MTT and TTP values of granulation tissues were(109.1±27.4)ml·100 g-1·min-1,(11.1±1.7)ml·100 g-1,(7.7±1.0)s, (19.8 ± 2.1)s respectively;Average BF, BV, MTT and TTP values of infectious tissues were(86.9 ± 7.7)ml · 100 g-1·min-1,(8.8±1.0)ml·100 g-1,(8.0±0.9)s,(19.7±1.3)s respectively. Average BF and BV values of the recurrent tumors group were higher than those of the granulation(q=4.89, 4.64 respectively,P<0.01)and infection group(q=7.52,7.71 respectively,P<0.01)respectively. Average BV values of granulation group was higher than that of the infection group(q=3.31,P<0.05), Average MTT and TTP values of recurrent tumor group were lower than those of the granulation (q=9.38, 12.48 respectively,P<0.01)and infection group(q=9.77, 11.53 respectively,P<0.05). There were no significant difference in average BF, MTT and TTP between the granulation and infection group. Conclusion MR PWI can be helpful in the diagnosis of complications and tumor recurrence in hypopharyngeal and laryngeal cancer after operation and radiotherapy.
