Objective To investigate the therapeutic effect of Budesonide inhalation for the children with chronic cough after Mycoplasma pneumoniae infection and its influence on the improvement of sleep quality.Methods One hundred children with chronic cough after Mycoplasma pneumoniae infection treated at Shsnghai Tongji Hospital(Tongji Hospital Affiliated to Tongji University) were selected from June to December 2016,and they were randornly divided into the Budesonide group and the Azithromycin group.The Budesonide group received the Budesonide inhalation,the atomized inhalation 1 mg each time,2 times a day,for 3 consecutive days,and 3 days later,they received ato-mization treatment once a day,for a total of 7 days.The patients in the Azithromycin group were given oral the Azithromycin treatment 10 mg/(kg · d) for 3 days.The efficacy and sleep scores of 2 groups were compared during the period.Results The cure rate of cough in the Budesonide group[8.0% (4/50 cases),32.0% (16/50 cases),38.0% (19/50 cases)]was higher than those in the Azithromycin group[0 (0/50 cases),4.0% (2/50 cases),6.0% (3/50 cases)] during 3,7,14 days,and the differences were all statistically significant (x2 =4.167,13.279,14.918,all P <0.05).The improvement rates of cough in the Budesonide group [28.0% (14/50 cases),28.0% (14/50 cases),26.0% (13/50 cases)]were higher than those in the Azithromycin group[10.0% (5/50 cases),10.0% (5/50 cases),8.0% (4/50 cases)] in treatment 3,7,14 days,and the differences were all statistically significant (x2 =5.263,5.263,5.741,all P < 0.05).Nighttime sleep scores returned to normal ratio and improvement rates during 3,7,14 days in the Budesonide group [8.0% (4/50 cases),32.0% (16/50 cases),42.0% (21/50 cases);30.0% (15/50 cases),30.0% (15/50 cases),30.0% (15/50 cases)],which were significantly higher than those in the Azithromycin group [0(0/50 cases),4.0% (2/50 caes),6.0% (3/50 cases);12.0% (6/50 cases),12.0% (6/50 cases),10.0% (5/50 cases)],and the differences were all statistically significant (all P < 0.05).Conclusions The inhalation of Budesonide can effectively treat chronic cough in children with Mycoplasma pneumoniae infection in children,and significantly improve the quality of sleep.Chronic cough after Mycoplasma pneumoniae infection may be related to airway hyperresponsiveness due to nonspecific inflammation.Inhaled corticosteroids should be selected rather than anti infective therapy.

Objective To identify novel mutations in the GATA6 gene associated with congenital atrial septal defects (ASD).Methods This was a case-control study.A cohort of 220 unrelated Han-race patients with congenital ASD and 200 unrelated ethnically matched healthy individuals used as controls,who were admitted to Tongji University Affiliated Tongji Hospital from January,2007 to October,2011,were recruited.The peripheral venous blood samples from the participants were prepared.All the coding exons and their flanking sequences of the GATA6 gene were amplified by polymerase chain reaction and sequenced using the di-deoxynucleotide chain termination technique.The acquired sequences were aligned with the sequences derived from GenBank by BLAST to identify the sequence variations.The software ClustalW was used to analyze the conservation of the altered amino acids.Results Three novel heterozygous missense GATA6 mutations,c.250G >A (p.A84T),c.649G >C (p.G217R) and c.1270A >C (p.S424R),were identified in 3 of 220 ASD patients,respectively.None of the three mutations was detected in 200 healthy control individuals.A cross-species alignment of GATA6 encoded protein sequences showed that the mutated amino acids were relatively conserved evolutionarily.Conclusion The identification of novel GATA6 mutations associated with ASD contributes to the reveal of the mechanism involved in the pathogenesis of ASD.
