Objective:To examine the social support mechanism of pet ownership and pet attachment.Method:A total of 321 pet owners and 418 non pet owners above 40 years in Beijing were measured with questionnaires.Results: (1) Pet ownership showed significant correlations with physical health and life satisfaction.Compared with non pet owners,pet owners had better physical health and life satisfaction (β=0.074;P<0.05,β=0.110;P<0.01).(2)Pet ownership could change the effect of recent life events on the physical health but not on life satisfaction (Z=2.59,P<0.01).(3) Pet attachment showed significant correlations with life satisfaction.The pet owners with more pet attachment had higher life satisfaction.Conclusions:Pet ownership has significant main effect of social support as well as buffering effect of social support.They appear as the significant moderating effects on recent life events and physical health.Pet attachment has significant main effect of social support,and few buffering effects of social support.

Objective: To investigate the relationship between attachment to pets and psychosecial develop-ment of children. Methods: Totally 147 children pet owners from grade 3 to grade 5 were selected from 11 primary schools in Beijing. They were asked to complete the Lexington Attachment to Pets Scale, Self Description Question-naire, Children's Loneliness Scale, and 2 dimensions of Children Social-life Adjustment Scale. Results: Attach-ment to pets was positively correlated with self-concept, pro-social orientation and living ability of daily life (r=0.47, 0.42, 0.34, Ps < 0.001), and negatively correlated with loneliness (r=-0.28, P <0.01) . Even the variables including study performance, interrelationship and socioeconomic status of family were taken as covari-ares, the higher attach group was better than lower attach group in self-concept, pro-social orientation, living abili-ty of daily life [(163.81±17.81)vs.(138.36±27.71), (46.19±4.25)vs.(40.64±6.93), (39.05±4.17)vs.(33.77±6.51); Ps<0.001] and loneliness [(28.53±11.08)vs.(34.79±10.96); P <0.01].Conclusion: There is apparent relationship between pet attachment and psychosocial development in children.

Objective To investigate the correlation between brain injury and premature infants with bronchopulmonary dysplasia (BPD)and to analyze the risk factors of brain injury in premature infants with BPD based on MRI changes.Methods A total of 1 13 premature infants diagnosed with BPD were studied as case group from January 2010 to December 2014 at the neonatal ward of Shengjing Hospital of China Medical University.One hundred and sixty-two premature infants without BPD were selected as control group.There were no significant differences in gestational age and birth weight between the two groups.All cases were per-formed MRI examination in hospital.The occurrence of brain injuries(white matter injury and intracranial hemorrhage)were compared based on MRI changes between the two groups,and the risk factors of brain in-jury in case group were analyzed.Results The case group and control group were performed MRI on (33.73 ±16.00)d,(24.40 ±12.29)d after birth respectively.The ratio of brain injury,intracranial hemor-rhage,cerebral white matter damage and severe brain injury of case group was higher than those of the control group(48.7% vs.32.7%,3 1.9% vs.21.6%,31.9% vs.21.6%,16.8% vs.8.6%,respectively).The differences were significant in the ratio of brain injury and severe brain injury (P =0.008,P =0.040,respec-tively).Logistic regression analysis showed that postnatal infection was a risk factor for brain injury of the case group(OR =2.21 ,95%CI 1.04 ~4.72,P ﹤0.05).Conclusion More brain injury(including the white matter injury and intracranial hemorrhage)and severe brain injury(including grade III ~IV intraventricular hemorrhage and periventricular leukomalacia)are detected in premature infants with BPD.Postnatal infection is a risk factor of brain injury for premature infants with BPD.

With the increased survival of the low birth weight,brain injury in the premature infants be-comes a problem of enormous importance. The introduction of the term “encephalopathy of prematurity” is the current recognition that preterm brain injury is a complex of white and gray matter damage. The combination of white matter injury and neuronal/axonal deficits constitutes encephalopathy of prematurity. The preterm infants develop primary destructive brain lesions,secondary degeneration and disturbance of maturation from hypoxia-is-chemia and inflammation,which leads to cerebral palsy,cognitive,behavioral,or language deficits. This article reviews the neuropathology,pathogenesis,therapy and neurodevelopmental disability of encephalopathy of pre-maturity.

Objective To analyze the clinical efficacy of desloratadine citrate disodium and fexofenadine in the treatment of refractory urticaria . Methods 100 patients with refractory urticaria were randomly divided into observation group and control group according to the digital table method, with 50 cases in each group.The control group were treated with desloratadine citrate disodium, and the observation group were treated with fexofenadine on the basis of control group.The efficacy, immunity function ( CD3 +, CD4 +, CD4 +/CD8 +) , the changes of inflammatory factors [ procalcitonin ( PCT) , C-reactive protein ( CRP) ] and the quality of life were compared between the two groups.The adverse reaction rate in two groups was recorded in two groups.Results The total efficacy in observation group (88.0%) was significantly higher than that in control group (72.0%)(P<0.05).The indicators of immunity function in observation group were significantly higher than those in control group(P<0.05).The inflammatory factors in observation group were significantly lower than those in control group ( P<0.05 ) .The sleep and exercise quality rate of the observation group were significantly higher than those in control group(86.0% vs.68.0%,84.0% vs.66.0%,P<0.05).Conclusion The combination of desloratadine citrate disodium and fexofenadine in the treatment of refractory urticaria has a good effect, can effectively improve the immune function, reduce the secretion of inflammatory factors, thus effectively relieve the clinical symptoms, improve their quality of life, and has high security.
