Objective To explore the efficacy of flupenthixol melitracen in the treatment of functional dyspepsia (FD) and its effects on receptivity expansion and visceral sensitivity.Methods A randomized,controlled,multi-centre study was carried out.The FD patients with depression were divided into anti-depression group and control group.The patients of both groups received omeprazole and mosapride treatment for eight weeks.The patients of anti-depression group added flupenthixol melitracen and psychotherapy.Before the treatment,by the end of the second,fourth,sixth and eighth week of the treatment,the scores of upper gastrointestinal symptoms and adverse effects of the patients of the two groups were recorded,the psychological status was evaluated by Hamilton depression scale and the gastric receptivity expansion and visceral sensitivity were assessed by water loading test (WLT).The data were analyzed by t test and chi-square test.Results Among two hundred and fifty enrolled FD patients with depression,245 patients (129 in anti-depression group,116 in control group) were enrolled in intention-to treat analysis.Before the treatment and by the end of the eighth week of the treatment,the scores of upper gastrointestinal symptoms of anti depression group were 12.23±4.45 and 2.31±2.13 (t=22.837,P=0.008),the control group were 12.29± 4.62 and 8.58±3.76 (t=6.708,P=0.184).By the end of the eighth week of treatment,the difference between the two groups was statistically significant (t =16.261,P＜0.05).By the end of the fourth and eighth week of treatment,the total effective rates of the improvement of upper gastrointestinal symptoms of anti-depression group were 76.0％ (98/129) and 83.7％ (108/129),control group were 14.7 ％ (17/116) and 25.9 ％ (30/116),the differences between the two groups were statistically significant (x2 =92.191 and 83.117,both P＜0.05).By the end of the eighth week of treatment,the total effective rate of the improvement of depression of anti depression group was 71.3％ (92/129),which was higher than that of control group (23.3％,27/116),the difference between two groups was statistically significant (x2 54.434,P＜0.01).Before the treatment,the maximum WLT volume of anti depression group was (850±130) mL,by the end of the eighth week of treatment was (1400±210) mL (t=25.292,P＜0.01).Before the treatment and by the end of the eighth week of treatment,the maximum WLT volumes of control group were (800± 120) mL and (960±140) mL (t=9.345,P＜0.01).All the adverse effects of anti depression therapy were mild.Conclusion The treatment of flupenthixol melitracen can improve the efficacy in patients with FD,relieve the depression status,improve gastric receptivity expansion and visceral sensitivity with a good safety and tolerability.

Objective: To explore the clinical effcacy and short-term survival rate of partial cardiac auto-transplantation for treating the patients with giant left atrium.
Methods: A total of 7 patients with rheumatic heart disease received partial cardiac auto-transplantation in our hospital from 2012-08 to 2013-05 were retrospectively studied. The patients were at the age of (54.9±5.0) years including 3 male, all of them combined with giant left atrium and pre-operative atrial ifbrillation (AF), 6 of them received radio-frequency ablation. All patients were monitored for their baseline condition, operative status, peri-operative mortality and complication occurrence for clinical analysis.
Results: All 7 patients received mitral valve replacement, 5 had aortic valve replacement and 2 had aortic valve-plasty, the mean aortic cross clamp time was (271.7±29.0) min. The average left atrial diameter decreased from (91.7±3.5) mm to (64.8±8.1) mm, left ventricular ejection fraction (LVEF) improved from (38.3±6.5) % to (47.4±6.1) % at discharge, allP<0.05; 4 patients recovered to sinus rhythm and no peri-operative death occurred. The patients were followed-up for (20.7±3.9) months, 1 year post-operational survival rate was 100%, 1 patient died at 17 months after operation and the average left atrial diameter was (56.3±3.4) mm in rest 6 patients at the last examination during follow-up period.
Conclusion: Partial cardiac auto-transplantation may obviously reduce left atrial diameter with good clinical effect in certain patients with giant left atrium.

Objective:To investigate the therapeutic effect of stroke patients received rehabilitation treatment at different medical units in the Rehabilitation Medical Association.Method:Totally 183 stroke patients were recruited from October 12,2012 to February 5,2016 by Shenzhen Rehabilitation Medical Association(SRMA).SRMA consists of 4 members,including the Second People's Hospital of Shenzhen,Shenzhen Nan'ao People's Hospital,Shenzhen Baoxing Hospital and Community Healthcare Center in Futian District,which belong to tertiary hospital,secondary hospital,and primary healthcare unit,respectively.According to the time of onset of stroke,all the patients were divided into recovery phase or sequelae phase.The rehabilitation facilities were standardized.All patients received rehabilitation treatment for 4 weeks,which included functional rehabilitation training of limb,functional electrical stimulation training,activities of daily living training.Fugl-Meyer Assessment(FMA),balance subscale of the Fugl-Meyer test(FMB),National Institute of Health Stroke Scale(NIHSS) and modified Barthel Index(MBI) before and after rehabilitation treatment were used to evaluate the effects.Result:The scores of FMA,FMB,NIHSS and MBI were significantly improved in all the groups after rehabilitation treatment(P ＜ 0.05).There was no significant difference in all assessments among the groups(P＞ 0.05).Conclusion:Based on the standardized rehabilitation treatment programs,the stroke patients come from the members of Rehabilitation Medical Association can achieve homogeneous effects after rehabilitation treatment.

Objective To investigate the effect of the psychological behavior intervention on the mental status and clinical symptom of patients with functional constipation. Methods All of 78 patients with functional constipation diagnosed by Rome m diagnostic code were randomly divided into study group (n =40) and control group (n = 38). The psychological behavior intervention was used in the study group, the caccagogue and symptomatic treatment was used in the control group. The self-rating anxiety scale(SAS),self-rating depressive scale (SDS) was analyzed and the improving of clinical symptom, adverse effect was compared before and after 4 weeks of treatment respectively. Results The scores of SAS and SDS in the study group significantly decreased after treatment [ (36.25±8.61 )scores vs (42.97±9.25 )scores, P<0.01 ;(38.81±6.53)scores vs (43.36±7.18 )scores ,P < 0.01].There was significant difference between the two groups after treatment (P <0.05).The effective rate of study group was higher than that of control group .(97.50% vs 84.21%,P <0.05). The rate of celiodynia, diarrhea and the recrudescence after the course of treatment in control group was 23.68%, 15.79% and 89.47% respectively, while this numerus in study group was 5.00%,2.50% and 5.00%. Conclusions Psychological behavior intervention plays an important role in the treatment of functional constipation. It can improve the mental status, clinical symptom, and decrease the adverse effect.

Molecular biological methods were used to construct the eukaryotic expression vectors of precore and core gene named EBO PreC/C. Then T1862, A1896, A1899 and A1896+A1899 variants were constructed by site mutagenesis in vitro. By PCR RFLP and sequencing ,T1862,A1896,A1899 and A1896+A1899 variants were obtained. Wild type and variants were transfected to HepG2 cells, and HBeAg was tested to observe the difference of HBeAg expression between wild type and variants. After stable expression in HepG2 cells, HBeAg was detected to be positive in cells transfected wild type and A1899 variants, and negative in cells transfected with T1862, A1896,A1896+A1899 variants. The construction of these variants will play an important pole in studying the relation of PreC/C mutations and HBV expression and replication of HBV genome.

Objective:To explore effects of frustration situation,resilience and positive music on attentional bias by a behavioral experiment.Methods:Totally 60 participants were chosen from 650 college students according to their scores in Connor-Davidson Resilience Scale (CD-RISC).Then,a 2(resilience,high/low)×3(experimental treatment,no frustration/frustration with positive music /frustration without any background)×2(vocabulary,posi-tive /passive)mixed design experiment was conducted to investigate the attentional bias of participants in emotional Stroop paradigm.Results:Reaction times to passive vocabulary were different significantly in three frustration situa-tions(P <0.01).Interaction of resilience and frustration on reaction time to positive vocabulary was significant (P<0.01).Among the participants with low resilience,reaction time to positive vocabulary in the situation without frustration or the frustration situation with positive music was longer significantly than that in the frustration situa-tion without any background [(476.3 ±85.6)vs.(456.0 ±54.0)vs.(427.1 ±61.1),P <0.05].Among the par-ticipants with high resilience,reaction time to positive vocabulary in the frustration situation without any background was longer than that in the situation without frustration [(472.1 ±82.9)vs.(432.4 ±53.2),P <0.05].Conclu-sion:It suggests that individuals may have obviously attentional bias to negative stimulus in frustration situation,and effects of resilience and positive music on attentional bias in situation may be obvious.
