OBJECTIVE: To detected the mechanism of allergic rhinitis associated with asthma with bioinformatics methods. METHOD: GenMAPP software was used to analyze the expression profile of nasal mucosa of seasonal allergic rhinitis(SAR) and SAR associated with asthma of oligonucleotide microarray (Affymetrix HG-U133-plus2). One the first step,of differentially expressed genes screening were done, then differential gene database retrieval was established, at last pathway analysis was performed. RESULT: 689 genes out of 47 000 analyzed transcripts of nasal mucosa of SAR associated with asthma were differentially expressed at least 4-fold, in which 233 genes were up regulated and 456 genes were down regulated. These differential expression genes participate in 69 bio-pathways, in which the interaction pathway between cytokine and cytokine receptor was most. Chemotactic factor CXCL12 and its receptor CXCR4 expressed in SAR associated with asthma patients were up-regulated predominantly, compared with that in SAR patients. CONCLUSION Multiple pathways were involved in the development of SAR and SAR complicated with asthma. The CXCL12/CXCR4 axis might play a main role in the allergic airway diseases.

Objective To investigate the diagnostic correlation and sensitivity of amplitude integrated electroencephalogram (aEEG),brainstem auditory evoked potential (BAEP) and cranial magnetic resonance imaging (MRI) for acute bilirubin encephalopathy (ABE) in the newborn.Method Term and near-term neonates (gestational age ≥ 35 weeks) with hyperbilirubinemia (the level of bilirubin over than 95th percentile) of high and intermediate risk group admitted in the neonatal ward of Guangxi Maternal and Child Health Care Hospital from Jan 2014 to Dec 2015 were recruited retrospectively.The infants were assigned to ABE group and non-ABE group according to the diagnostic criteria of ABE.The clinical data of the newborns were collected and the diagnostic correlation between clinical diagnosis and aEEG,BAEP and cranial MRI were analyzed.The receiver operating characteristic (ROC) curve was adopted to assess the diagnostic efficiency of the peak level of serum bilirubin,aEEG,BAEP and cranial MRI on the early diagnosis of ABE.Result A total of 152 newborns with hyperbilirubinemia were recruited,including 33 cases in the ABE group and 119 cases in non-ABE group.(1) The results of aEEG and MRI were marginally positively correlated with clinical diagnosis of ABE (aEEG:r =0.487,P ＜ 0.001;MRI:r =0.220,P=0.018),while the results of BAEP were closely related to the clinical diagnosis of ABE (r =0.593,P ＜ 0.001);(2) The results of BAEP and MRI on the diagnosis of ABE were positively correlated with those of aEEG (BAEP:r =0.424,P ＜ 0.001;MRI:r =0.307,P ＜ 0.001).(3) The area under the ROC curves for predicting the onset of ABE were 0.899 for the peak level of serum bilirubin,0.767 for BAEP,0.738 for aEEG and 0.590 for MRI.Conclusion There was the correlation on the diagnosis of ABE among the methods of aEEG,BAEP and MRI.The combined diagnosis of the three methods could play a complementary role.The aEEG contributed to the early diagnosis of ABE with high sensitivity.

OBJECTIVE: Explore the model of universal NICU newborns' hearing screening in high-risk neonates, preliminary understanding factor of hearing damage. METHOD: Transient evoked otoacoustic emissions (TEOAE) and automatic auditory brainstem response (AABR) were used to detect newborns' hearing in 13 315 objects, that is newborns' hearing screening in NICU with TEOAE test who not pass, 42 days after will use AABR rescreening. Children's Hearing Center of Guangxi Child Health Hospital will diagnose the newborns that did not pass in 3 months. RESULT: In these 13 315 newborns, 5 151 subjects who did not pass the initial screening, 1910 subjects who also did not pass after 42 days, 1167 subjects cannot pass the rescreening after 3 months, 642 subjects were diagnosed congenital hearing impairment by Brainstem Auditory Evoked Potential Test, the rate is 4.82%. CONCLUSION TEOAE and AABR are the suitable model of universal newborns' hearing screening in high-risk neonates.
