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 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 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.

Gastrointestinal benign stricture is a common disease with symptoms of dysphagia,abdominal pain and difficult defecation,which severely impair the quality of life for patients.Endoscopic intervention is the first-line treatment,and the available methods include balloon dilation,local drug injection and stent insertion,etc.Endoscopic incision was first used for the treatment of Schatzki's rings,and later it was used for the treatment of other gastrointestinal benign strictures,and the promising results were achieved.

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

Background:Hepatic veno-occlusive disease( HVOD) is a disease characterized by hepatomegaly,jaundice, ascites,weight gain and lack of effective treatment currently. Our prophase research showed that ligustrazine had therapeutic effect on Sedum aizoon induced HVOD in mice. Aims:To investigate the mechanism of therapeutic effect of ligustrazine on Sedum aizoon induced HVOD in mice. Methods:A total of 115 mice were randomly divided into 4 groups:mice in group A were intragastrically administrated with 30 mg·kg-1 ·d-1 Sedum aizoon to induce HVOD and served as model group;mice in group B were given 30 mg·kg-1 ·d-1 Sedum aizoon + 100 mg·kg-1 ·d-1 ligustrazine and served as low dose ligustrazine intervention group;mice in group C were given 30 mg·kg-1 ·d-1 Sedum aizoon + 200 mg·kg-1 ·d-1 ligustrazine and served as high dose ligustrazine intervention group;mice in group D were given 30 mg·kg-1 ·d-1 PBS and served as normal control group. After 30 days,all the mice were sacrificed. HE staining and Masson staining were performed for histological examination. The mRNA and protein expressions of tissue factor(TF),nuclear factor(NF)-κBp65 and early growth response factor( Egr)-1 in liver tissue were determined by RT-PCR and Western blotting, respectively. Results:HE staining and Masson staining histological examination showed that ligustrazine could obviously ameliorate the pathological injury of liver tissue in HVOD mice. Compared with group D,the mRNA and protein expressions of TF,NF-κBp65,Egr-1 were significantly increased in group A( P < 0. 05). After intervention with ligustrazine,the mRNA and protein expressions of TF,NF-κBp65,Egr-1 were significantly decreased( P < 0. 05), especially in group C,and no significant differences were found between group C and group D(P > 0. 05). Conclusions:Ligustrazine has therapeutic effect on HVOD,the possible mechanism is that ligustrazine could interrupt the activation of coagulation system by reducing the expression of TF via down regulating the expressions of NF-κBp65 and Egr-1,especially in high dose ligustrazine group.

Objective To construct recombinant plasmids containing various functional domains of APC protein and detect their expression in HCT-116 cells. Methods Five APC gene fragments were amplified by PCR with whole APC gene as template and primers designed according to APC cDNA sequence and mutation cluster domain. The five obtained fragments were cloned into eukaryotic expression vector pEGFP-N3 to generate recombinant pEGFP-N3-APC1-5. Sequence of the inserted gene was identified and analyzed after restriction enzyme digestion. Liposome-mediated recombinant plasmid pEGFP-N3-APC was transfected into HCT 116 cells and identified by green fluorescence. RT-PCR was employed to validate the expression of recombinant vectors in cells. Results Recombinant pEGFP-N3-APC1-5 were confirmed by restriction enzyme digestion and sequence analysis. The plasmids could be expressed in HCT-116 cell line detected by fluorescence microscope. Results of RT-PCR made clear that vectors constructed could be expressed in HCT-116 cells. Conclusion The relative efficient expression of five recombinant expressive vector in HCT-116 cell line may provide an experimental basis for selecting specific therapy peptide for colorectal cancer.

Objective To investigate the risk factors and incidence of gas-related complications in peroral endoscopic myotomy for easophageal achalasia.Methods Clinical data of 216 patients with achalasia treated by peroral endoscopic myotomy from August 2011 to November 2013 were collected.Potential risk factors for gas-related complications were analyzed by univariate and multivariate analysis.Results The incidence of gas-related complications was 10.2％ (22/216).Univariate analysis showed risk factors for complications were Sigmoid type esophagus,simple longitudinal incision for tunnel entry,tunnel width ≤3 cm,degree of myotomy,and operation time (P ＜ 0.05),while multivariate analysis showed the risk factors were Sigmoid type esophagus,simple longitudinal incision for tunnel entry,and tunnel width ≤3 cm(P ＜ 0.05).Conclusion Simple longitudinal incision for tunnel entry,tunnel width≤3 cm and sigmoid type esophagus are risk factors of gas-related complications in POEM,while myotomy depth is not.
