Objective To explore the value of dexamethasone(DEX) for neuronal cell injury and death by observing the effect of DEX on excitatory amino acid(EAA) and monoamine neurotransmitter in cerebral tissue of neonatal rat with hypoxia-ischemia.Methods Hypoxic-ischemic neonatal rat models were established,the levels of EAA and monoamine neurotransmitter in cerebral tissue were analyzed by using capillary electrophoresis and fluorospectrophotometry method.The rats were divided into 4 groups: small dose DEX group pre-treated with DEX(0.5 mg/kg) prior to hypoxia-ischemia,large dose DEX group pre-treated with DEX(10 mg/kg) prior to hypoxia-ischemia,HIE group and shamful operation group.Results The levels of EAA and monoamine neurotransmitter contents in HIE group were significantly higher than those in shamful operation group(P0.05).EAA contents of large dose DEX group greatly decreased compared with HIE group (P

Allergic diseases such as allergic asthma, allergic der-matitis, allergic rhinitis, are polygenic diseases, involving the interaction between the environment, genes and immunity. In the past few decades, the incidence rate of allergic diseases in-creased predominantly and influenced the quality of people's lives seriously, so looking for new targets for the prevention and treat-ment of allergic diseases and drugs with less adverse reaction be-comes a hot topic for researchers. MicroRNAs(miRNAs)are a class of endogenous non-coding small RNAs that mediate nega-tively posttranscriptional regulation of gene expression by targe-ting specific mRNA sequences to inhibit the translation of mR-NAs. They are widely involved in the biological processes of cell differentiation, immune response and tumor development. The study shows that miRNAs can control the occurrence and devel-opment of allergic diseases. Studying the regulatory role of miR-NAs in allergic diseases has important implications for exploring the immunopathological mechanisms and discovering new thera-peutic targets of drugs.

Aim To investigate the method of establishing the atopic dermatitis mice model induced by calcipotriol ( MC903 ) . Methods Induction dose exploratory experiment: since d 0, 0.33,1,3 nmol MC903 was smeared on the right ear of BALB/c mice in each dose group respectively , for 7 consecutive days . The ear swelling degree of the mice was observed every day and the bilateral ears thicknesses were measured .The materials were drawn and analyzed in d 3 and d 7.Induction days exploratory experiment: 2 nmol MC903 was smeared on the right ear of BALB/c mice, for 14 consecutive days .The ear swelling degree of mice was observed every day and the bilateral ears thicknesses were measured .The histopathological examination of the right ear was conducted in 3 d, 7 d, 11 d and 15 d respectively .The tissue homogenate of the mice right ear was prepared .The ex-pressions of thymic stromal lymphopoietin (TSLP),IL-33, IL-4 and IFN-γin the homogenate , CD40 +,CD86 +,the DC surface markers and ILC2 contents in the peripheral lymph nodes were detected.Results ①1,3 nmol MC903 induced ear swelling in mice was significantly increased in d 3, the levels of TSLP and IL-4 were significantly increased .The level of IL-33 in 3 nmol dose group was increased significantly in d 7.② The right ear swelling of 2 nmol MC903 induced atopic dermatitis mice was significant , the ear thickness was increased gradually and reached the peak in d 14.The histopathological examination of the mice ear tissue showed in d 7, the right ear tissue of the mice was swelling and red , the capillary vessels were dilated and the infiltration of inflammatory cells was obvious .The ear in-flammatory symptoms maintained and gradually aggravated for 15 days.Compared with the normal mice , MC903 increased the TSLP level in the right ear tissue homogenate significantly in d 3 and then decreased gradually .The levels of IL-4 and IL-33 were increased significantly in d 7 and then decreased gradually .The levels of ILC2, CD40 +, CD86 + in the peripheral lymph nodes were increased in d 7 and d 15.Conclusion The atopic derma-titis mice model can be successfully established using 2 nmol MC903 induced mice for 7 days.Appropriate testing point of TSLP is d 3.Appropriate testing point of IL-33 and IL-4 is d 7.

By analyzing the epidemiological and clinical features of adenovirus in children with acute respiratory tract infection (ARTI), we provide a theoretical basis for early clinical diagnosis and treatment. Nasopharyngeal secretions were collected from 3480 children with ARTI, who were hospitalized at the No. 2 Hospital of Changzhou from January 2011 to December 2012. Adenovirus were detected using direct immunofluorescence assays. A total of 80 samples were positive for adenovirus (2.30%). The rate of adenovirus infection during 2011 was significantly higher than that in 2012, and the infection rate was higher in summer and autumn than in winter and spring. The infection rate was 1.14% among children aged < 1-year-old and the rates were higher among children in other age ranges. Adenovirus was found to be an important ARTI pathogen in children in Changzhou, mainly affecting children older than 1 year. ADV infections have various clinical presentations, but affected children tend to be severely ill with poor outcomes.
