Objective To confirm the advantages resources of well-adapted Korean left-behind children,in order to provide reference for implementation of mental health for community left-behind children.Methods The research instruments included 4 questionnaires:The Left-Behind Children Resiliency Scale,Perceived Social Support Scale,Adolescent Self-Rating Life Events Check List and SocioDemographic Characteristics of Respondents.470 Korean left-behind children were selected by convenience sampling method and the data underwent analysis by SPSS 16.0.Results Well-adapted Korean left behind children were significantly higher than the mal-adjusted children in resilience,social support,education level of guardians and contact frequency of parents with children.The frequency of life events and stress was Rower than the mal-adjusted children.Conclusions Advantages resources of well-adapted Korean left-behind children include:good social support and infrequent occurrence of adverse life events and stress.

OBJECTIVE To study the content and distribution characteristics of thymic stromal lymphopoietin (TSLP) in nasal mucosa of murine model of allergic rhinitis.METHODS 6-week-old BALB/c mice were divided into control group and experimental group.Mice of experimental group were sensitized by means of dropping OVA in nasal cavity and intraperitoneal injection of OVA. Meanwhile,mice of control group were dealt with physiological saline instead of OVA.The content of TSLP in nasal mucosa of mice was tested by means of real-time PCR and its distribution was detected by means of immunohistochemistry staining.RESULTS The content of TSLP was obviously higher in nasal mucosa of experimental group than that of control group.It was distributed mainly in lamina propria and on the surface of epithelium.CONCLUSION TSLP may play an important role in allergic rhinitis of the mice.

OBJECTIVE: To understand the usage of MP3 and effects on hearing of middle school students in Xi'an, and discuss controlling strategies. METHOD: Stratified random cluster sampling method was used in the 1567 middle school students in Xi'an through questionnaire survey, ear examination and hearing examination, data were analysed by the SPSS13.0 statistical software. RESULT: 1) The rate of holding MP3 in the middle school students was 85.2%. Average daily use time was (1.41 +/- 1.11) h. 2) The noise group of pure tone hearing threshold was significantly higher compared with the control group (P<0.01), and increased the detection rate of hearing loss with the increasing use of MP3. 3) The detection rate of symptoms increased with the increasing use of MP3. CONCLUSION The usage of MP3 can harm hearing in middle school students, which can result in neurasthenic syndrome.
