After the advantages and disadvantages of appointment registration systems in different large hospitals of Beijing were compared, the problems in their appointment registration systems were analyzed and suggestions were put forward for establishing the public appointment registration systems with powerful systematization and compati-bility which are integrated into the EMR system of Beijing.

Objective To observe the long-tern efficacy and safety of rosiglitazone in treatment of type 2 diabetic pa- tients.Methods 59 patients on a regimen of glipizide or glipizide+mefformin with poor glycaemic control were added rosiglitasone 8mg/d and observed for 3 years,and the dose of glipizide would be reduced 7.5mg/d when FPG

Objective To investigate the potential role of respiratory syncytial virus (RSV) in wheezing episode in children, and to assess the association of the thromboxane A2 receptor gene (TBXA2R) T924C polymorphism with wheezing after RSV infection. Methods From may to december in 2008, one hundred and twenty-five asthmatic children who were suffering from acute episode were recruited as cases and 49 healthy children as controls in our Polymerase chain reactions-Restriction fragment length polymorphism (PCR-RELP) techniques were used to detect the TBXA2R SNP. RSV IgM and IgG were measured by ELISA. Results RSV specific antibody was positive in 57 asthmatic patients (45.6% ,57/125) and 8 controls (16.33% ,8/49) ,with significant difference between the two groups ( χ2 = 12. 890, P = 0. age asthmatic group and 76. 92% (30/39) in the <3 years of age asthmatic group, with significant difference between the two groups (χ2 = 22. 420, P = 0. 000 ). The genotypes distribution in the asthmatic patients was significantly different from that in the controls(χ2 = 5. 346, P = 0. 021). The frequency of TC and CC genotypes in the cases was significantly higher than that in the control group. The allele frequencies of T and C allele were similar in the two groups ( χ2 =2.660, P=0.103). Conclusions RSV infection was one of the factors that associated with asthma acute episode, especially in children younger than 3 years. The TC,CC genotypes increase the chance of wheezing in children infected by RSV.

Objective To analyze the correlation between electrocardiogram exercise stress test and coronary artery stenosis degree.Methods A total of 150 patients who performed electrocardiogram exercise stress test were selected,and then coronary angiography were performed within 2 weeks.The sensitivity,specificity,positive predictive value and accuracy of electrocardiogram exercise stress test for diagnosing coronary artery stenosis degree were analyzed.Results Compared with coronary angiography,the sensitivity,specificity,positive predictive value and accuracy of electrocardiogram exercise stress test for diagnosing coronary heart disease were 75％(48/64),74％ (64/86),69％(48/70) and 75％ (112/150),respectively,for diagnosing coronary artery disease were 31％ (19/62),42％ (37/88),27％ (19/70) and 37％ (56/150),respectively.Conclusions Electrocardiogram exercise stress test as a simple,feasible and noninvasive method,has a good concordance with coronary angiography and a high correlation with coronary heart disease,a low correlation with coronary artery disease.It can be used as a good way to screen patients with coronary heart disease.

Objective To discuss the clinical effect of pulmicort respules inhalation in children with acute infectious laryngitis.Methods We selected acute infectious laryngitis in our hospital from November 2015 to November 2016,106 children were divided into two groups,the control group and the observation group of 53 cases,of which the control group of children with conventional treatment,the observation group to take Pulmicort respules inhalation treatment,the two comparison(P<0.05).The total effective rate of the observation group and the control group were 100％and 90.56％respectively(P<0.05).Results The treatment effect of the observation group and the control group were observed and compared(P<0.05),and the improvement of the observation group after treatment and the time of symptom extinction were significantly better than that of the control group(P<0.05); The clinical symptoms of both groups before and after treatment were improved(P<0.05).Conclusion The treatment of children with acute infectious laryngitis by atomizing inhalation of pulmicort respules can obtain obvious therapeutic effect and reduce the adverse reaction caused by improper use of drugs,(fever,cough,wheezing,etc.)have a good improvement in clinical application worthy of recognition.

AIMTo establish a collagen sandwich system (CSS) wit h self-prepared collagen for rat hepatocytes culture[FQ(14*2。46,X-WZ]in vitro, and study the effect of CYP3A substrates on cyt o chrome P450 activities of hepatocyte cultured by CSS. METHODSS terilized type Ⅰ collagen was prepared from rat tail tendons. The morphology of hepatocyte cultured by collagen coated (CC) and CSS method was investigated and compared. Activities of ALT, AST, and LDH in aliquots of extracellular medium w ere measured by biochemical assay. CYP1A, CYP2E1 and CYP3A activities of hepatoc ytes were also determined. RESULTSBy CSS method, the shape of hepatocytes was maintained, and the structure of cells was integrated after cult ivated for 6 d. However, in CC method after 3 d, hepatocytes dropped from the co llagen matrix, and the activities of ALT, AST and LDH in aliquots were increased . As compared with control group, in CSS cultivated hepatocytes, the activities of CYP3A increased 33%, and CYP2E1 decreased 45% by nimodipine, and CYP3A was in duced 1 94-fold (P

Objective To investigate whether spinal cord is involved in the analgesic effect of propofol.Methods Fifteen adult SD rats of both sexes weighing 195～223g were randomly divided into three group of five animals each: control group received normal saline intraperitoneally(ip), fentanyl group received fentanyl 0 1mg/kg and propofol group propofol 100mg/kg ip 2 min later 4% formalin 150?l was injected subcutaneously into the planta region of right hindpaw 1h after formalin injection animals of all three groups were anesthetized with pentobarbital sodium ip After induction of anesthesia chest was open and 100 ml of normal saline was infused via left ventricle then followed by 4% formalin infusion for fixation of tissue, 90 min later spinal cord, L 3 5 sect, was removed for determination of c fos expression in spinal cord using fos immunohistochemistry technique Results In control group in less than 10 s after formalin intraplantar injection the animals were agitated, restless, lame and paw licking In fentanyl group and propofol group the righting reflex was suppressed for (19 4?7 8) min and (7 2?1 5)min and no pain response was seen during this period When righting reflex recovered the pain response was much lighter than that in the control group Formalin stimulation induced c fos expression was seen only in the ipsilateral spinal cord Both fentanyl and propofol significantly suppressed c fos expression evoked by formalin stimulation The number of fos like immunoreactivity neurons(FLIN) decreased by 57 8% and 36 3% respectively(P

Objective Intestinal subepithelial myofibroblasts(ISEMFs) exist throughout the gastrointestinal tract. Due to their ability to secrete cytokines, prostaglandins, growth factors, and extracellular matrix proteins, they are thought to play critical roles in inflammation, repair, fibrosis and neoplasia. The goal of this study was to investigate the relationship between ISEMFs and ulcerative colitis by establishing the method of ISEMFs detection from the biopsy specimens. Methods ISEMFs in colon biopsy specimens (15 from active ulcerative colitis patients and 20 from controls) were detected by immunohistochemistry with smooth muscle actin monoclonal antibody. Results ISEMFs existed in a subepithelial location of colon, were located in the basement of epithelial, and were oval or scaphoid in appearance. ISEMFs in active ulcerative colitis (71.3?9.1) were more than those in controls (56.3?6.9) per field of high power ( P
