Objective To evaluate the scan technique and clinical value of multi-slice spiral CT angiography(MSCTA) of coronary artery.Methods MSCTA was performed in 86 patients,and 25 of them were also investigated with selective coronary angiography(SCA).The imaging quality of MSCTA in different scanning condition were analyzed.The patency of coronary artery and other branches were examined.The distribution and extent of coronary arterial stenoses were assessed.The findings demonstrated on MSCTA were compared with those seen on SCA.Results(1)The imaging quality on MSCTA of coronary artery was significant better in patients with a heart rate below 60 beats per minute,contrast flowing rate 3.0~3.5 ml/s,volume 120~150 ml and delayed time 22~25 s;(2)in 25 cases,of 71 coronary artery and branches without stenoses examined with MSCTA,68 had identical appearance on both MSCTA and SCA.The distribution and extent of 19 coronary arterial stenoses revealed by MSCTA were correlated exactly with SCA in 29 coronary arterial stenoses.The negative and positive predicted value were 95.8% and 65.5% respectively.Sensitivity,specificity and accuracy were 86.4%,87.2% and 87.0% respectively.Conclusion MSCTA as a noninvasive examination is a valuable method in detecting diseases or variations of coronary artery.

0.05).Conclusion:HLA-DQA1*0102 and DQA1*0104 were associated with protection from chronic HBV infection and development of LC,respectively.There was no significant association between HLA-DQA1 and development of HCC in chronic HBV infection patients.

Osteosarcoma is the most common maligant in skeletal system.Its treatment is always the focus of most clinical research workers.This article is a brief overview of the research progress of the therapy for osteosarcoma.In addition to neoadjuvant chemotherapy,surgical treatment,this article also includes molecular targeted therapy,gene therapy,and immune therapy.These new advances will contribute to the clinical work.

OBJECTIVE:To study the interaction of cefprozil (CE) with bovine serum albumine (BSA). METHODS:Under the temperatures of 289,299 and 309 K,the interaction of CE with BSA for 50 min had been studied by fluorescence quenching, UV spectrometry and synchronous fluorescence spectroscopy. Quenching constant(KSV)and speed constant(Kq)were calculated by Stern-Volmer equation. Static quenching constant(KLB)was obtained by Lineweaver-Burk equation,and UV spectrogram was used to determine the type of quenching. Double logarithmic equation was used to calculate the binding constants (Kb) and the number of binding site(n). Thermodynamic equation was used to obtain ΔH,ΔS,ΔG. Hill's coefficients(nH)was obtained by Hill equa-tion. RESULTS:At three different temperatures,with CE concentration increasing,fluorescence intensity of BSA decreased regular-ly. The value of KSV,Kq,KLB,Kb and n and nH decreased with the temperature increasing. ΔH,ΔS and ΔG were lower than 0. The numbers of binding sites were approximately equal to 1 and nH<1. CONCLUSIONS:CE statically quench the fluorescence of BSA,and the binding of them have been found to certain extent. The process of binding is spontaneous exothermic process. The main binding forces include Hydrogen bonds and Van der Waals forces,and primary binding site for CE is located at sub-domain ⅡA of BSA. There was some negative cooperative effect. CE would not affect the conformation of BSA. The binding site of CE and BSA is near by tyrosine residue.

This paper introduces the concept,the research paradigms and the related theory of the attentional blink,and reviews the relevant researches about the attentional blink of the children and adults with ADHD in the last 10 years.Compared to normal subjects,children and adults with ADHD did show more severe AB effect,and adults with ADHD showed more eye movement behavior.In future studies,standardized RSVP paradigm should be set up to provide convenience for the comparison of results of studies,and find out what kind of processing restrictions will affect the characteristics of different age ADHD groups in the time dimension of attention.In addition,ADHD and inhibitory control related closely,consideration should be given to the combination of inhibitory control paradigm and AB paradigm.

Hypoglycemia is a common metabolic problem in newborn infants,which might lead to brain injury even brain death when it keeps extremely low for a long time.Therefore,it is of great importance to monitor blood glucose in neonates,especially in groups of infants who are at risk of hypoglycemia,in order to identify and treat this condition and prevent adverse neurological outcomes promptly.It is given that infant of a diabetic mother,preterm neonate,low birth weight and asphyxia are its risk factors.Relative to blood glucose monitoring methods in clinical,continuous glucose monitoring system is comprehensive,continuous and with low pain.Continuous glucose monitoring system has been applied in high-risk neonates of hypoglycemia in recent years.It is of great help to understand the complete picture and change trend of blood glucose,optimize blood glucose management,study newborn glucose metabolic characteristics and the relationship between hypoglycemia and brain damage,so as to define and manage neonatal hypoglycemia.

AIM: In this article, gastrointestinal tumor-related historical archives of pathology in our hospital were reviewed in order to acknowledge gastrointestinal stromal tumors (GIST). METHODS: These cases were rediagnosed correctly , these tissues were labeled with some antibodies such as CD117, CD34, ?-SMA, S-100, and their clinical characteristics were explored. RESULTS: CD117, CD34 were expressed widely in GISTs ,the percentage of positive expression was CD117 (50/56, 89.3%), CD34 (37/56, 66.1%), respectively, ?-SMA, S-100 were (17/56, 30.4%), (4/56, 7.1%), respectively, desmin was negative in these cases. Among them, 29 cases were benign and borderline, 27 cases were malignant. The percentage of occurring in stomach and intestine was 91.1%. CONCLUSION: CD117, CD34 are expressed significantly in GIST, these might be assistant markers for GIST diagnosis. GISTs mostly occurred in stomach and intestine.
