Objective To investigate the efficacy of flupentixol and melitracen(Deanxit) in treatment of non-erosive reflux disease(NERD) and non-responding to proton pump inhibitor. Methods Fifty eight NERD pa-tients were randomly divided into two groups, the treatment group (n = 29) and control group (n = 29). Patients in control group were given esomeprazole 40 mg qd. Patients in the treatment group were given the same drug plus Deanxit 1 Tab qd. The clinical effect was evaluated and scored by Hemihon Anxiety Rating Scale (HAMA) after 4 weeks. Results The total efficacy rate of the treatment group was higher than control group (P < 0.01),and HAMA was lower in the treatment group than in control group (P < 0.01). Conclusions Adjuvant treatment of Deanxit combined with esomeprazole is effective to NERD patients who did not respond to proton pump inhibitor, can greatly improve anxious disorders.

Objective To analyze the clinical feature and diagnostic methods of patients with ischemic colitis(IC) for improving the recognition and the efficacy of therapeutic treatment. Methods Retrospective analysis of the clinical data of 30 cases of IC,including the medical history,clinical symptomatology,endoscopic appearance, histopa-thology,treatment and prognosis. Results IC occurred most of frequently in mid-aged and elders,the male-female ra-tio was 1:2.3,83.3% of the patients were over 60 years old, and most them had underlying disease. The most com-mon presenting features were sudden abdominal pain and bloody stools. Endoscopic lesions located mainly in left co-lon. Mucosal edema,erosin and submucosal bleeding were common pathological feature. Vasodilator drugs and compre-hensive medical therapy had good effects. The average duration for healing or improving was 10 days. Conclusions IC should be suspected in all elder patients with sudden abdominal pain and bloody stools. Colonoscopy is helpful for diagnosis. The prognosis is good in most cases and with rapid recovery.

Objective To explore the efficacy of prophylactic bilateral internal iliac arteries balloon occlusion in treatment of women with pernicious placenta previa complicated with placenta accreta.Methods A retrospective analysis was conducted on 41 cases of pernicious placenta previa with placenta accreta admitted to Guangzhou Women and Children's Medical Centre from January 2010 to December 2012.The study group (n=13) underwent prophylactic bilateral internal iliac arteries balloon placement before cesarean section and occlusion after delivery.The control group (n =28)received conventional haemostasis during cesarean section.The amount of blood loss and blood transfusion during the operation,the perioperative hemoglobin level,operation time and duration of hospitalization of the two groups were compared with t test or Chi square test.Results The volume of intraoperative hemorrhage of the study group was lower than of the control group [(1429±875) ml vs (4600± 2090) ml,t=6.840,P=0.000],the amount of intraoperative blood transfusion in the study group was also lower [(920±438) ml vs (3600± 1225) ml,t=10.251,P=0.000].Operation time and postoperative duration of hospitalization of the study group were shorter than those of the control group [(197±45) min vs (284±44) min,t 5.850,P=0.000; (6.7±1.3) d vs (8.2± 2.2) d,t=2.272,P=0.029].There was no statistical difference on hysterectomy rate between the two groups [11/13 vs 89％(25/28),x2=0.181,P 0.670)].In addition,two cases of reoperation,one case of pulmonary edema,two cases of coagulation disorder,one case of venous thrombosis in lower limbs,one case of renal dysfunction and pulmonary edema were reported in the control group,but none in the study group.Conclusions.Prophylactic bilateral internal iliac arteries balloon occlusion is effective in reducing intraoperative blood loss,transfusion,and relative complications in patients with pernicious placenta previa complicated with placenta accreta.

OBJECTIVE： To observe the changes of insoluble particles of shuanghuanglian in quantity after mixed with benzylpenicillin,cefradine and dexamethasone in normal saline.METHODS： Using ZWF-4D particle counter,the number of insoluble particles in sizes of ≥ 2.0μ m,≥ 5.0μ m,≥ 10.0μ m and ≥ 25.0μ m was counted and compared before and after mixed with above-mentioned three drugs.RESULTS： The insoluble particles of Shuanghuanglian were obviously increased after mixed with benzylpenicillin,the particles in sizes of ≥ 5.0μ m,≥ 10.0μ m and ≥ 25.0μ m increased twice,23 and 94 times respectively.The insoluble particles were also increased after mixed with cefradine or dexamethasone,however,the increase rate was lower in comparison with that mixed with benzylpenicillin.CONCLUSION： Shuanghuanglian,used in combination with above-mentioned drugs,should be put into separate infusion bottle to avoid the increase of insoluble particles and ADRs.

Methods was assessed by immunohistochemical method ot SP in paraffin tissue sections of 40 PBC and paratumor normal lung tissue. Results The positive rate of TNF-a in cytoplasm of carcinoma cells was 47.5 % (19/40), and it was not found in all paratumor normal lung tissue(P< 0.05). ConclusionTNF-a gene expressed in some patients with broncho genic carcinoma. The growth of bronchogenic carcinoma is related to TNF-a gene.

AIM: To evaluate the effect of captopril on action potential duration and outward delayed rectification potassium current (Ik). METHODS: Action potentials were recorded using a conventional glass microelectrode filled with 3 mol/L KCl solution. Membrane patch clamp whole cell recording technique was used to investigate the Ik current maximum in the holding potential - 50 mV, lasting time 100 ms, command potential + 40 mV. RESULTS: The action potential duration of 30%, 50% repolarization (APD30, APD50) and ERP were significantly prolonged, but APD90 wasn' t prolonged significantly when captopril group compared with ischemic group. The amplitude of Ik increased significantly in ischemic group, but significantly decreased in captopril group and in captopril + ischemic group. The shapes of current - voltage relationship were unchanged among groups, but significantly upward in ischemic group and downward in captopril and captopril + ischemic group. CONCLUSION:Captopril exerts electrophysiologic action due to decreasing delay outward rectification potassium current and prolonging action potential duration of APD30, APD50 and ERP.
