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 investigate the gastric empty and electrogastrogram(EGG) in patients with renal insufficiency before and after hemodialysis, and to study the enteric nervous system (ENS) in experimental acute renal failure rats.Methods The comparisons of gastric emptying and EGG before and after hemodialysis were carried out in 15 patients with uremia who have gastrointerstinal symptoms. Acute renal failure models were also established. The neuroplexus of ENS and levels of some gut hormones were investigated. Results The EGG and gastric emptying were abnormal in patients with uremia before hemodialysis, but improved after dialysis. The neuroplexus of ENS with positive nitric oxide synthase(NOS) staining in rats with acute renal failure was significantly decreased. The levels of gastrin, vasoactive intestinal peptide and motilin in rats with acute renal failure were (159.1?55.6)?g/L, (121.6?48.9)pg/L, and (6.32?3.55)pmol/L, respectively, which were significantly different from those of the control group(P

Objective To observe the curative effects of treatment with Edaravone for acute massive cerebral infarction.Methods 48 patients with acute massive cerebral infarction were randomized into the treatment with Edaravone group(Edaravone group,24 patients) and the conventional treatment control group(control group,24 patients).Two groups patients were admitted conventional treatment for cerebral infarction.Edaravone group patients were admitted with Edaravone 30 mg into 100 ml saline infusion introvenously,twice a day,linked 20 ～ 25 d.Respectively before and after the treatment,neurologic function dificit score(NDS),plasma fibrinogen(Fib) content,coagulation blood function,activity of superoxide dismutase(SOD) were examined.The clinical efficacy was compared between the two groups.Results NDS of tow groups after treatment were significantly lower than those of before treatment,activity of SOD were significantly increased than those before treatment(all P0.05).Significant efficiency ratio of the Edaravone group(87.5%) was significantly higher than that of the control group(45.8%)(P

objective: To study the effects of laser engineered net shaping(LENS) in the manufacture of dental prosthesis. Methods: An experiment LENS system, including a 5 kW continuous wave CO 2 laser, a four-axes numerical control working table and powder feeding system, was built up, by which, a rectangular LENS component was made from Rene95 alloy powder. The microstructure of the component was observed with scanning electron microscope and ESA analysis. Results: The size of the component was 120 mm?15 mm?15 mm , and the wall of the component was perpendicular to the base. The microstructure of the component was made up of fine columnar dendrite with the length of 10～20 ?m, 10 times less than that of the cast made from the same material. The main elements of the powder distributed homogeneously,the negative effect of segregation could be limited and the properties of the component could be improved.Conclusion: The microstructure of components made by LENS is much better than that of those made by casting from the same material.

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.
