Background:Functional gastrointestinal disorders(FGIDs)is a common disease of digestive system which severely affects the quality of life. Recently,more and more attentions have been paid to the relationship between FGIDs and psychological factors. Aims:To investigate the relationship between FGIDs and psychological factors and related treatment. Methods:A total of 270 patients with FGIDs admitted from Sept. 2013 to Sept. 2014 at Anhui No. 2 Province People’s Hospital were enrolled. Hamilton Anxiety Scale(HAMA)and Hamilton Depression Scale(HAMD)were used to evaluate the mental state of patients,and symptom severity of digestive system was scored. Patients with psychological abnormalities received conventional therapy to relieve digestive symptoms,and those who failed from conventional therapy were assigned into refractory group and others were assigned into response group. Patients in refractory group were further divided into conventional therapy group and combined therapy group for receiving paroxetine in addition to conventional therapy. Results:The rates of anxiety and depression were 61. 5%(166 / 270)and 57. 0%(154 / 270),respectively. The scores of HAMA and HAMD were positively correlated with the score of digestive symptoms(r = 0. 585,P < 0. 01;r = 0. 584,P <0. 01)in patients with anxiety and depression in response group. The scores of HAMA,HAMD and digestive symptoms in response group after conventional therapy were significantly decreased(P < 0. 05),while the scores of HAMA and HAMD in refractory group after therapy were significantly higher than those in response group before therapy(P < 0. 05). The scores of HAMA,HAMD and digestive symptoms in combined therapy group were significantly lower than those in conventional therapy group(P < 0. 05). Conclusions:Relationship is found between FGIDs and psychological factors,and antidepressants might contribute to the amelioration of symptoms of FGIDs.

Objective: To detect the changes of serum level of connective tissue growth factor (CTGF) in patients with ST-segment elevation myocardial infarction (STEMI) and to study the correlation between CTGF level and the maximal activity of creatine kinase-MB (CK-MB). Methods: Our research included 2 groups of patients: STEMI group and unstable angina (UA) group. All patients were treated in our hospital from 2013-07 to 2014-06,n=50 in each group. In STEMI group, the serum levels of CTGF were examined by ELISA at 24h, 2, 7, 14 days of onset, and in UA group, CTGF level was examined at 24h of onset. The CK-MB activity levels were measured in STEMI group at the same time points by immunosuppression method. Results: The serum level of CTGF in UA patients at 24 h of onset was (10.34 ± 2.00) ng/mL, and in STEMI patients were (16.76 ± 3.17) ng/mL at 24h, (29.87 ± 4.90) ng/mL at 2d, (45.02 ± 8.35) ng/mL at 7d and (31.61 ± 4.40) at 14d. The CTGF levels in STEMI group at different time points were all higher than UA group at 24h of onset,P<0.01. In STEMI group, the CTGF levels were increasing from 24h to 7d, then decreasing at 14d, allP<0.01. In STEMI group, the highest protein concentration of CTGF was positively related to the maximal activity of CK-MB at 7 days of onset (r=0.859,P=0.000). Conclusion: CTGF expression has been up-regulated in STEMI patients which might be related to myocardial ifbrosis. The protein level of CTGF is related to MI size, it shows certain predictive value in relevant patients.

Objective: To explore the clinical and anatomical characteristics of coronary slow lfow (CSF) in relevant patients.
Methods: We summarized the patients without coronary angiography (CAG) proved coronary stenosis (stenosis < 40%) while with TIMI indicated CSF in our hospital from 2013-01 to 2015-01. The patients were divided into 2 groups: CSF group, n=56 patients having at least 1 major coronary artery with TIMI frame counts > 27 and Control group,n=55 patients with normal coronary lfow. The related laboratory indexes were examined and relationship between MCV and CSF was studied by multi-logistic regression analysis.
Results: In CSF group, MCV 90.4 (87.48, 92.65) fL and RDW-CV 12.5 (12.30, 13.18) % were lower than those in Control group 92.3 (90.1, 94.3) fL and 13(12.7, 13.4) %,P<0.05; while MCHC 337 (332, 347) g/L and the number of left circumlfex distal braches involved 3 (2, 4) were higher than those in Control group 327.5 (322, 338) g/L and 2 (2, 3),P<0.05. Multi-logistic regression analysis showed that MCV was negatively related to CSF (partial regression coefficient= -0.138, P=0.015), Spearman rank correlation analysis presented that MCV was negatively related to TIMI frame counts (r= -0.201, P=0.009).
Conclusion: Deformability of red blood cells might be involved in pathogenesis of CSF in relevant patients.

Objective The Rex shunt has been used to treat children with extrahepatic portal hypertension by creating a venous bypass between the superior mesenteric vein and the left portal vein to circumvent the extrahepatic portal venous obstruction.This retrospective study aimed to analyse our results in the use of this novel approach.Methods 52 patients with cavernous transformation and obstructed main portal veins were treated by Rex shunts.Results The age of children was 1.4 ～ 12 year,the mean age was 3.7 years.The patients were followed up from 1.5 to 5 years.In 48 patients,there was no recurrence of gastrointestinal bleeding after surgery making an efficacy rate of 92.3％.In the recurrence group,the postoperative venous pressure in the superior mesenteric vein was (27.6 ± 3.2) cmH2O (1 cmH2O =0.098kPa) which was significantly higher than the non-recurrence group (23.5 ± 3.1)cmH2O.The difference between the pre-and post-Rex shunting was significantly lower in the recurrence group (5.7 ± 1.8)cmH2O than the non-recurrence group (11.7 ± 3.3) cmH2 O,P ＜ 0.05.Thus,a low reduction in postoperative pressure was an early manifestation of poor prognosis.Conclusions The Rex shunt was safe and efficacious.The degree of reduction in postoperative venous pressure in the superior mesenteric vein could be used to predict recurrence of gastrointestinal bleeding.

Objective Non-contrast enhanced magnetic resonance angiography ( MRA) has become the focus of research at home and abroad .The aim of the article was to optimize the scan parameters of renal artery with inflow-sensitive inversion recovery ( IF-IR) MRA. Methods 30 cases of renal artery patients into two groups were collected from December 2013 to May 2014 in our hospi-tal.They were divided into stenosis group(n=12) and non-stenosis group(n=48).IFIR-MRA sequences were carried out on each patient by using various BSP-TI with 1200,1300 and 1400 ms, all other parameters were identical .The image signal to noise ratio, a renal artery branch and venous artifact were evaluated by two experienced radiologists , and the best BSP-TI was obtained from different groups. Results BSP-TI=1400 ms was optimal for renal artery stenosis group while 1200 ms was the most suitable for non-stenosis group. Conclusion IFIR-MRA of renal artery can achieve better image quality of renal artery and its branches and it is feasible in clinical routine practice , especially for those patients with renal insufficiency .
