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 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.

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 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.

Objective To investigate the clinical status of post-core crown in anterior teeth aesthetical restoration and to observe its effect. Methods 126 cases of anterior teeth in patients with mild deformity,restored with post-core crown after informed consent meanwhile conducted clinical follow-up observation. Results In addition to 2 cases of disease after root canal treatment, 1 incisal and labial surface of porcelain fracture, other cases achieved desired results in the way of self-satisfaction,clinical efficacy and x-ray observation and periapical films. Conclusion Post-core crown in anterior aesthetical restoration has a unique position and clinical efficacy.

Objective: To confirm the pathogenesis and diagnosis of pediatric Fisher's syndr ome.Methods: Clinical manifestations and Cerebrospinal fluid (CSF) were compared and studied in 22 patients diagnosed as Fisher's syndrome.Results:Twenty- two cases of Fisher's syndrome both had the characteristics of ophthalmoplegia and cerebella ataxia,and had different degrees of incomplete fl accid paralysis in the ar ms and legs. In about half of 22 cases, the CSF showed divergence phenomenon of the protein and cell. Conclusion: Fisher's syndrome is a specific or variant type of AIP involving the cranial nerves, in which the cerebellar ataxia is taken as a main symptom and sign .

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.

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.

Objective To analyze the CRE and UREA result of university students,and establish the refer-ence interval for CRE,UREA adapted to this university.Methods Performing serum analysis of 2 926 freshmen for CRE,UREA with the automatic biochemical analyzer ( Olympus AU400 ) .Results Reference intervals were get among freshmen as CRE:74.00-109.00μmol/L (M),59.00-85.00 μmol/L (F),and it was different between male and female(Z =-27.27,P <0.01);UREA:2.70 -6.70mmol/L (male aged 16 -24 years),1.90 -5.70mmol/L (female aged 16-24 years),2.30-6.57mmol/L (male aged >24-45 years),1.94-5.11mmol/L ( female aged 25-45 years) .Conclusion The reference intervals disaggregated by sex and age are initially estab-lished.

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.
