Objective To analyze and determine the clinical chatacteristics and treatment of suqerior mesenteric venous thrombosis.Methods We reviewed the medical records of all 32 patients who were diagnosed as with SMVT in Peking Friendship Hospital from 1985 to 2005.Results Thirty-two patients were diagnosted as SMVT,11 patients were with chronic superior mesenteric venous thrombosis(median age 46.6 years,ranging 32～78 years),without acut abdomen;22 cases were acute superior mesenteric venous thrombosis(median age 45.9 years,range 19～64 years).The main symptoms at the presentation were abdominal pain(100%),abdominal distension(100%),acute abdomen(100%),vomiting(68.2%,15/22),an fever(36.4%,8/22).Misdiagnosis rate 59.1%(13/22),death rate 31.8%(8/22).Conclusion The presentations of ASMVT have some relatively characteristics.The clinical diagnosis of ASMVT can be confirmed on the basis of abdominal CT and selective superior mesenteric arteriography in early phase.

Objective To analyze clinical characteristics of acute mesenteric venous thrombosis (AMVT) and its diagnositic methods. Methods Medical records of 16 patients diagnosed as SMVT in Friendship Hospital of Beijing during October 1985 to October 2002 were collected and analyzed, and its clinical characteristics and diagnostic methods were summarized.Results Median age of the 16 patients was 45.9 years, ranged from 19 to 64 years. Their main symptoms at admission were abdominal pain (100%), abdominal distension (100%), acute abdomen (100%), vomiting (75%, 12/16) and fever (75%, 12/16), with an underdiagnosis rate of 75% (12/16) and case-fatality ratio of 44% (7/16).Conclusions AMVT had several specific manifestations. Early clinical diagnosis for AMVT could be established on the basis of abdominal color doppler ultrasonography, diagnostic abdominocentesis, CT and selective superior mesenteric arteriography, and its case-fatality could be lowered with early surgical operation.

Objective To evaluate the efficacy and safety of endoscopic mucosal resection (EMR) for rectal carcinoid tumors. Methods From January 2006 to January 2009, EMR was performed in 28 patients with rectal carcinoids, who were followed up to evaluate the therapeutic effect and safety. Results Tumor diameters varied from 0.4 cm to 1. 2 cm (mean 0.7± 0. 2 cm). Negative resection margin was a-chieved in 26 cases (92. 9% ), tumor margin within 0. 1 cm of resection margin in 1 (7. 1% ) , and two margins coincided in 1 patient (7. 1% ). Hemostasis was performed with metal clips in 14 patients (50% ) and argon plasma coagulation (APC) in 9 (32. 1% ). Except for rectal bleeding in 1 patient (3. 6% ) , no other complications were observed. There was no recurrence in any patients during a follow-up of 6-36 months. Conclusion EMR is a useful and safe method for treatment of small rectal carcinoid tumor which does not cross submucosal layer.

Objective To investigate the efficacy of acupuncture combined with doctor-nurse cooperation mode on stroke-associated pneumonia in patients with acute stroke. Methods 67 patients of acute stroke within 1 week in our hospital from March, 2013 to January, 2015 were randomly divided into control group (n=35) and treatment group (n=32). Both groups received neurological routine treatment and systematic rehabilitation training by professional physiotherapists under general nursing mode. The treatment group received acupuncture treatment under doctor-nurse cooperation mode additionally. Incidence of stroke-associated pneumonia, swallow function and aspiration rate were recorded. Results Compared with the control group, the incidence of stroke-associated pneumonia significantly decreased in the treat-ment group after treatment (χ2=4.615, P=0.032). The retention volume of epiglottic vallecula and pyriform sinus (tdilute barium=21.01, tthick barium=19.85), the duration of pharynx period (tdilute barium=17.03, tthick barium=13.68), and the start time of pharynx period (tdilute barium=19.63, tthick barium=17.86) were less in the treatment group than in the control group (P<0.05). In the test of dilute barium, the aspiration rate was lower in the treatment group than in the control group (χ2=4.03, P=0.044), however, there was no significant difference between 2 groups in the test of thick bari-um and solid food (P>0.05). Conclusion Acupuncture combined doctor-nurse cooperation mode may decrease the rates of aspiration and stroke-associated pneumonia in acute stroke patients through improving their swallow function.

Objectiye To evaluate the therapeutic efficacy and safety of (endoscopic sphincterotomy, EST) plus balloon dilation for difficult bile duct stones. Methods Patients with difficult common bile duct stones on endoscopic retrograde cholangiopancreatography (ERCP) from March 2008 to December 2009 were randomly divided into 2 groups to receive EST or EST plus balloon dilation ( EST + EPBD), respectively. The success rate of complete stone removal, number of endoscopic sessions, the rate of using mechanical lithotripsy and the complication rate related to the procedure were compared between the 2 groups. Results Compared with EST alone, EST plus balloon dilation resulted in similar outcomes in terms of overall successful stone removal rate (2/62 vs. 2/61 ) and early complication rate (4/62 vs. 6/61, P ＞0. 05). However,EST group needed more sessions ( EST 15/46 vs. EST + EPBD 5/57, P ＜0. 05) and use of mechanical lithotripsy to achieve complete removal of stones ( EST 12/61 vs. EST + EPBD 4/61, P ＜0. 05 ). Conclusion EST plus balloon dilation is as safe and effective as, but more convenient than EST, for endoscopic removal of common bile duct stones.

Objective To explore the value of computer-animal-clinic sequential training model in colonoscopy training.Methods Sixty-five gastroenterologists without any experience in colonoscopy were randomly assigned to 2 groups to accept a two-week′endoscopy training with computer simulator or with com-puter-animal-clinic sequential training.Both groups underwent at least 10 hours of training with a computer-based simulator,and sequential training group also underwent animal simulator training for 2 days in first week,then both groups underwent clinical endoscopy training in the second week.Performance parameters including cecal intubation,procedure duration and degree of comfort were evaluated.Results The training group had higher cecal intubation rate (46.28% VS 35.79%;P <0.01 )and shorter procedure duration (9.05 ±2.12 min VS 11.15 ±3.12 min;P <0.05)and less degree of comfort (5.18 ±1.41 VS 6.78 ± 2.15;P <0.05).The sequential training group was much better in performance than the other group in colonoscopy training.Conclusion Computer-animal-clinic sequential training model is effective in providing trainees with colonoscopy skills in improving the success rate,shortening the teaching times and lessening the uncomfortable of patients.

Objective To evaluate the efficacy and safety of fluoroscopy guided frequency-doubled double-pulsed laser lithotripsy for removing difficult bile duct stones. Methods From March 2008 to December 2009, patients with difficult bile duct stones were divided into cholangioscopy guided group ( n = 21 )and fluoroscopy guided group ( n = 19) to receive corresponding treatments. The success rate of complete stone removal and the complication rate related to the procedure were compared between the two groups.Results There are no significant differences between 2 groups in regarding of either success rate of complete stone removal ( 19/21, 90. 5% in cholangioscopy guided group vs. 17/19, 89. 5% in fluoroscopy guided group, P ＞0. 05 ) or rate of procedure related complication (4/21, 19. 0% in cholangioscopy guided group vs. 3/19, 15. 8% in fluoroscopic guided group, P = 0. 559 ). Conclusion Frequency-doubled doublepulsed laser lithotripsy guided by cholangioscopy or fluoroscopy are both safe and effective.

Objective To observe the effect of acupuncture combined with moxibustion on heart rate variability (HRV) in patients with post-stroke depression. Methods 120 patients were divided into control group (n=60) and treatment group (n=60). Both groups took fluoxetine and accepted acupuncture therapy, and the treatment group accepted moxibustion additionally. Hamilton Depression Rating Scale-17 (HAMD-17) and the change of HRV were compared before and after treatment. Results The score of HAMD was lower, and the reductive ratio was higher in the treatment group than in the control group (P<0.05). The standard deviation of the mean of qualified normal sinus interval (SDNN) and standard deviation of sequential five-minute R-R interval means (SDANN) increased in both groups after treatment (P< 0.05), and were higher in the treatment group than in the control group (P<0.05). The root mean square differences of successive R-R intervals (RMSSD) and percentage of differences between adjacent normal sinus intervals greater than 50 ms (PNN50) decreased in both groups after treatment (P<0.05), and were lower in the treatment group than in the control group (P<0.05). The low frequency (LF), high frequency (HF) and LF/HF were higher in both groups after treatment (P<0.05), and were higher in the treatment group than in the control group (P< 0.05). Conclusion Acupuncture combined with moxibustion therapy can better adjust the function of autonomic nerve and reduce depression in patients with post-stroke depression.
