Objective:To explore the relations between freshmen's self-identity status,personality characteristics and mental health status.Methods:188 new students were asked to complete the questionnaires of mental health scale and personality scale from the China college students mental health evaluation system,and eollnge students self- identity status scale.Results:①the most status of identity is achievement(43.1%),then the identity diffusion (30.9%);②male students in compare with female,were more likely in achievement status(60.7?13.8/53.9?11.4,P0.406);③the achieve- ment status had obvious negative correlation with depression,dependency(r=-0.17～-0.24),the diffusion status had obvious positive correlation with depression,social-withdrawal,and impulsion(r=0.15～0.34);④active,ac- commodating,tough-minded personality characteristics had obviously negative correlation with mental symptoms(r= -0.16～-0.56).Conclusions:encourage college students to form the achievement ego-identity status,to be ac- tive,accommodating and tough-minded,will be helpful for their psychological health.

Scientific research fund is an important component of scientific research management,and an important precondition for scientific research activity. This paper explores the existing problems in the scientific research fund management of medical university, and suggests that only standardization of the fund management can guarantee the efficiency the fund use, and realize the scientificity, normalization, rationality of the research fund management, which will all contribute the improvement of research quality.

Objectives:To observe the effects of enteral nutrition on cell immune in patients with acute renal failure. Methods:The changes of cell immune were compared in 22 patients with acute renal failure before and after EN treatment. Results:There were significant improvements in cell immune after 10 days of EN. CD3,CD4,CD4/CD8 and NK acitivity( P

Objective To develop a convenient and effective molecular authentication method for identifying Dendrobium nobile from other species of Dendrobium Sw.Methods Based on rDNA ITS sequences of D.nobile and other species of Dendrobium Sw.of Huangcaos and Fengdous,unusual sequence sites were confirmed and an allele-specific diagnostic primer pair was designed for D.nobile. Diagnostic PCR was performed using the primers with the total DNA of D.nobile and other species of Dendrobium Sw.as templates to establish the positive PCR condition for D.nobile.Results An about 300 bp DNA positive fragment was amplified from D.nobile with anneal temperature at 66 ℃ and anneal time at 40 s,whereas no any DNA fragment was amplified from the rest 39 species of Dendrobium Sw.Conclusion D.nobile could be effectively distinguished from other species of Dendrobium Sw.by diagnostic PCR with allele-specific diagnostic PCR,which is not only effective and specific,but also simple and timesaving,and has a comprehensive application prospects.

At present, too much importance has been attached to avian influenza globally. The reasons for this and the possibility of contagion from human to human were discussed . As to prevention and control of avian influenza, suggestions were made to find early human cases in local hospitals and local CDC (Center for Disease Control and Prevention), to make the laboratory staff follow the bio-safety principle for diagnosis of avian influenza.

OBJECTIVE:To provide the reference for the set-up of precautions against flu pandemic in China.METHO_DS:RNA of influenza viruses isolated from flu children in flu seasons between 2003 and 2005 in Beijing was extracted and amplification of M2 gene fragments associated with ion channel were performed by one step reverse transcription–polymerase chain reaction(RT-PCR).The sequencing of amino acid was determined,and its bioinformation was analyzed with software,then the positions of amino acid for resistance to amantadine were detected.RESULTS:20 of 31 isolated strains were resistant to amantadine,the percentage of which was 66.7%.CONCLUSION:The monitoring of drug resistance to flu viruses should be strengthened in China.

Apolipoprotein E (ApoE) has gene polymorphism (ε2,ε3,and ε4).It has been confirmed that ApoE structural and functional abnormlities are closely associated with the hyperlipidemia,formation of atherosclerosis,and its severity,while both hyperlipidemia and atherosclerosis are the risk factors for ischemic stroke.In recent years,although the relationship between the ApoE gene polymorphism and ischemic stroke has been extensively studied,the conclusions are not consistent.This article reviews the correlation studies between the ApoE gene polymorphism and ischernic stroke.

Objection]To study the clinical effect of self-prescribed jianpihuazhuoxiaoyu decoction in treating the patients with non-alcoholic liver of fat. [Methods]45 patients were treated with self-prescribed Jianpihuazhuoxiaoyu decoction in treatment group and other 45 patients with Polyene Phosphatidylcholine Capsules and Ursodeoxycholic Acid. Observe the patients'body mass index(BMI),radiological changes,liver function(AST/ALT) and lipids(TG/TC/HDL/LDL). [Results] The total effective rates were 91.3%,82.6% respectively, compared with the control group,the treatment group significantly improved liver function,lipid content decreased,obesity weight was effectively controlled and reduced,sonogram also showed improvement in the texture of the liver,compared with control group there were significant differences(P<0.05),difference was statistically significant.
