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 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: 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.
