Intracerebroventricular administration of purified EC induced a fall in rectal temperature of rabbits with an increase in ear skin temperature. Only 1/80th the amout of purified EC injected i. v. produced a comparable fall in rectal temperature when injected into the lateral ventricle of rabbits. ICV administration of purified EC resulted in a more rapid fall in rectal temperature than i. v. administration. This evidence strongly supports the hypothesis that EC has a primary site of action in the central nervous system.After intravenous administration of purified EC, with a fall in rectal temperature there was a significant decrease in levels of cyclic AMP in the cerebrospinal fluid of rabbits, but no change was found in levels of cyclic GMP in the cerebrospinal fluid. These data suggest that EC might induce hypothermia in rabbits by lowering levels of cyclic AMP in the brain and that cyclic GMP might not be involved in hypothermia caused by EC.

Objective To test the reliability and validity of the collective self-esteem scale for freshman.Methods 800 freshmen finished the Collective Self-Esteem Scale,the Life Satisfaction Scale,and Self-esteem Scale.Results The confirmatory factor analysis shows that collective esteem includes membership esteem,private collective esteem,public collective esteem,and importance to identiy intemal consistency a of the scale and the 4 components of the scale ale between0.6357and 0.8369.All components of the scale except importance to identity have significantly positive correlation with life satisfaction and self-esteem.(0.14＜r＜0.41,P＜0.01).Gids have more scores than boys in total collective esteem(t=3.38,P＜0.01),Private CSE and Importance to Identity (t=3.32,P＜0.01).Conclusion The revised collective self-esteem scale for freshmen has sound reliability and validity.It is a good instrument for measuring collective self-esteem of Chinese freshman.

Objective: To explore the relationships among stress,burnout and depression.Methods: 270 college students were investigated with the Burnout Measure(Short version),Life Events Scale and Self-Rating Depression Scale.Results: The correlations between burnout,life events and depression were all significant statistically(P

Objective;To test the relationship between Collective Self-Esteem,Self-Esteem and Depression,Anxiety.Methods;800 freshmen completed the Collective Self-Esteem Scale,the self-Esteem Sale,Self-Rating Depression Scale and Self-Rating Anxiety Scale.Results;①The rate of slight depression was 21.6%;moderate depression,5.9%;high depression,1.6%.The mean of anxiety was 42,the mode of anxiety was 36.②The predicting effects of Self-Esteem,private collective self-esteem and public collective self-esteem on depression were significant(P

Objective To explore the prevalence of hypertension in children with obstructive sleep apnea syndrome(OSAS).Methods Ninety snoring children were enrolled and stayed in sleeping monitor unit for a night.24 h ambulatory blood pressure(ABP)monitoring and polysomnography were simultaneously carried out. The children were classified depending of [Apnea Hypopnea Index(AHI≥5)] as OSAS group and(AHI

Objective　To explore the method of chemical synth esis of L-alanyl-L-glutamine dipeptide. Methods　 L-alanyl-L -glutamine dipeptide was prepared by condensation and ammoniation reaction of L -glutamine and 2-D-chloropropionyl chloride. The physico-chemical properties of this dipeptide were identified with melting point determination, amino acid analysis, elements analysis and MS and its purity was determined with HPLC. Results　This dipeptide was confirmed good in quality by physico-chem ical determination. Conclusion　Dipeptide synthetized by this me thod is simple, convenient and with good guality.

OBJECTIVE： To analysis the adverse reactions of angiotension converting enzyme inhibitor（ ACEI） ， so as to deepen the understanding to the ARDs and improve the therapeutic effect of ACEI METHODS： The therapeutic effects and ARDs of ACEI were retrospectively reviewed and the incidence of ARDs induced by ACEI and the relationship between different ACEIs and their ARDs were analyzed RESULTS： （ 1） The incidence of ARDs of ACEI was 12％  Stimulating cough， parageusia， gastrointestinal tract discomfort， skin rash， itch of skin， hypotension， headache， dizziness， proteinuria and angioedema were the common symptoms （ 2） Of five kinds of ACEIs， captopril induced the highest incidence of ARDs and stimulating cough， parageusia， gastrointestinal tract discomfort， skin rash and itch of skin were the most common manifestations CONCLUSION： Stimulating cough， parageusia， gastrointestinal tract discomfort and skin rash are the most common symptoms of ARDs， and the symptoms will disappear when drug administration is discontinued

Objective: To explore the impact of personality and locus of control on job burnout.Methods: Chinese Maslach burnout inventory,Eysenck personality questionnaire and internal-external locus of control scale were used to examine 247 judges.Results: Introversion-extroversion was a significant predictor of exhaustion(P

OBJECTIVE:To review drug use in the pediatric outpatient department of our hospital.METHODS:1000pediatric prescriptions during Aug.1to Aug.20,2004and another1000during Aug.1to Aug.20,2005were collected from the pediatric outpatient department of our hospital,and which were subjected to statistical analysis using international indicators of rational drug use and DDDs.RESULTS:The usage of injection accounted for12.3%in2004and11.4%in2005.The usage of anti-infectives stood at84.20%in2005,accounting for46.11%of total drug consumption sum.Azithromycin and cefaclor respectively dominated the first place on the lists of consumption sum and DDDs.CONCLUSION:The practice of Prescription Management Rules(trial)helps improving the use of injections in the pediatric outpatient department of our hospital.However,there are still many problems,which needs to be tackled in the application of anti-infectives and further intervention measures needs to be taken.

BACKGROUND:Porous tantalum, characterized as high porosity, low elastic modulus, high friction coefficient, stable biological properties, good compatibility and typical structural properties, has been the focus in medicine, especial y in orthopedics. ＜br> OBJECTIVE:To review the biological characteristics of porous tantalum, including its mechanical properties, compatibility, and biological activity. ＜br> METHODS:A computer-based search of PubMed, CSTJ, Wanfang and VIP databases was done for articles relevant to porous tantalum published from 1990 to 2014 using the keywords of“porous tantalum, biological character, orthopedic applications”both in English and Chinese. ＜br> RESULTS AND CONCLUSION:Porous tantalum, with high porosity, low elastic modulus, high friction coefficient, and good compatibility, has become increasingly popular in medicine, especial y in orthopedics. At present, porous tantalum is used in the preparation of the integrated acetabular cup, total hip arthroplasty acetabular cup, acetabular reinforcing pad, porous tantalum metal rod, tibial plateau prosthesis and patel ar prosthesis and tibial plateau prosthesis. The short-term fol ow-up of porous tantalum implants in orthopedic surgery has been reported. And clinical data, radiology, histological analysis of the removed material have proved the practicability and safety of the porous tantalum. But the long-term effects of porous tantalum remain to be confirmed.
