0.05),but the rate of recurrent bleeding in EBL group was significantly lower than that in EIS group (6.3% vs. ~40.0% , P0.05). Conclusions EBL is an effective and safe ~endoscopic treatment for hemorrhagic Dieulafoy's lesion.

Objective To explore the curative effect of the umbilical single port laparoscopic salpingectomy for tubal ectopic pregnancy.Methods 296 cases with tubal pregnancy were divided into single-hole group and the conventional group.Mter the operation,incision cosmetic results and patients'satisfaction were compared and analyzed in two groups.Results (1) The anal exhaust time of single hole group and conventional group was (32.6 ± 11.6) h,(34.1 ± 10.2) h (P =0.883).The intraoperative blood loss was (48.7 ± 15.2) ml (41.5 ± 10.9) ml (P =0.313).There was no significant differences(P ＞ 0.05).Operative time of single hole group was (62.6 ± 21.6) min,which was longer than that of the conventional group (42.7 ± 17.6) min,the difference was statistically significant (P =0.000).The ambulation time and demand analgesia patients of single-hole group were significantly lower than the conventional group(P =0.003,P =0.001).(2) In single-hole group,cosmetic results determined a good rate of 96.8％ and patients expressed dissatisfaction rate of 1.2％.cosmetic results of the conventional group judged good rate of 86.4％.patients expressed dissatisfaction rate of 9.3％.The judged good rate of cosmetic results between the two groups had statistically significant difference (P =0.004),and patients expressed dissatisfaction rate of single-hole group was lower than the conventional group.Conclusion For patients with tubal pregnancy,the trekking transumbilical single hole laparoscopic salpingectomy is a more minimally invasive,feasible and safe gynecological surgical procedures and with better cosmetic results,although there is a certain degree of difficulty.

Objective To investigate the clinical effect and safety of laparoscopic-assisted vaginal radical hysterectomy (LAVRH) and pelvic lymphadenectomy in early-stage cervical cancer.Methods The clinical data of 126 patients with cervical cancer were retrospectively analyzed.63 cases received LAVRH surgery were considered as study group,and 63 cases received laparotomy were selected as control group.The operation time,intraoperative blood loss,intestinal function recovery time,the average hospitalization days,surgical complications,recurrence incidence,etc were compared between the two groups.Results The operation time,intraoperative blood loss,intestinal function recovery time,the average hospitalization days had significantly statistical differences between two groups(P ＜0.05).The surgical complications and recurrence rate had no significantly statistical differences between two groups (P ＞0.05).Conclusion LAVRH and pelvic lymphadenectomy has the advantages of minimally invasive,less blood loss,faster recovery,etc.It is an effective method for the treatment of early-stage cervical cancer.

Objective: To itvestigate the effect of Antidepressant on refractory irritable bowel syndrome(IBS).Methods: A self-control study of subclincal dosage of antidepressants therapy(fluoxetine 10mg/d or paroxetine 10mg/d) for 12 weeks in 46 patients with refractory IBS was performed.The clinical outcomes were evaluated by indexs of symptom severity and symptom frequency and the score of Hamiton depession scale(HAMD) and Hamiton anxiety(HAMA).Results: All 46 cases completed the therapy.After the course of treatment,indexes of symptom severity and symptom frequency and the scores of HAMD and HAMA were significantly lower than those before treatment(P

Objective To investigate the value of external counterpulsation and cervical traction therapy on patients with vertebral artery insufficiency syndrome. Methods Based on the criteria of clinical diagnosis, 90 patients with vertebral artery insufficiency syndrome were randomized into three groups. The group A was treated with external counterpulsation (30 cases), the group B with cervical traction (30 cases)and the group C with cervical traction plus external counterpulsation (30 cases). Results There was better therapeutic effects in group C as compared with groups A and B (P0.05). Conclusion External counterpulsation and traction therapy are effective in the treatment of the vertebral artery insufficiency syndrome.

Objective To explore the effect of recombinant pEGFP-N3-APC vectors carrying various APC functional domains on the expression of β-catenin in human colorectal cancer cells HT-29.Methods The recombinant plasmids were transfected into HT-29 cells mediated by lipofectamine~(TM) 2000, and detected by green fluorescence and RT-PCR. Western blot was applied to detect β-catenin expression level in HT-29 cells after transfection, and gray scales of electrophoresis strips were analyzed by SPSS 13.0.Results Green fluorescence and RT-PCR made clear that all 5 recombinant plasmids were successfully expressed in HT-29 cells. Western blot showed that β-catenin expression level in HT-29 cells was not affected after being transfected with pEGFP-N3-APC1, pEGFP-N3-APC2 and pEGFP-N3-APC3, and was distinctly affected after being transfected with pEGFP-N3-APC4 and pEGFP-N3-APC5, especially the later one. Conclusion The selected APC5 gene fragment with 15-amino acid repeats and SAMP repeats, which is relatively short, can degrade β-catenin level in HT-29 cells and may be applied in the gene therapy.

0.05), but the rate in eradicating varices after the first treatment session was significantly higher(66.7% vs. 10.0%, P 0.05); the comparison of the Kaplan Meier estimate of survival did not show any statistically significant differences in the two groups. Conclusions The sandwich method leads to longer retention of sclerosant in varices and is far superior to EVL alone with respect to the rate in eradicating varices after the first treatment session and prevention of rebleeding and variceal recurrence. The study shows the sandwich method is the optimal endoscopic method for the treatment of EVB.

Objective To analyze the expressions of p27 and PCNA and cell apoptosis in ulcerative colitis and colon cancer.Methods The expressions of p27 and proliferation cell nuclear antigen(PCNA)proteins in colorectal cancer,ulcerative colitis and normal colon were analyzed by StrptAvidin-Biotin Enzyme Complex immunohistochemical methods.The apoptosis was detected using terminal uridine deoxynucleiotide nick end labeling(TUNEL) histochemistry.Results The level of PCNA expression in colorectal cancer and ulcerative colitis was markedly higher than that in normal colon(P

Objective To investigate the clinical efficacy of body weight supported treadmill training (BWSTT) for the recovery of walking ability and comprehensive function after thoracolumbar spinal cord injury (SCI).Methods Sixty patients with SCIs in a thoracolumbar segment were assigned to a treatment group or a control group with 30 in each.Both groups received similar conventional rehabilitation training,but the patients in the treatment group were additionally treated with BWSTT (30 to 40 min,once daily,5 d/week,30 days for a course,a total 3 courses).The American Spinal Injury Association lower-extremity motor function assessment (ASIA),a functional comprehensive assessment (FCA),the walking ability assessment from the FCA (WA) and the modified Barthel index (MB1) were used in the assessment of the two groups before and after treatment.Results There were no significant differences in the two groups＇ average ASIA,FCA,WA or MBI results before treatment.After treatment ASIA,FCA,WA and MBI scores had all increased significantly in the treatment group compared with before treatment,and were significantly higher than in the control group.Conclusion As a supplement to conventional rehabilitation,BWSTT can improve walking ability and comprehensive function significantly after thoracolumbar spinal cord injury.
