Relationship between obstructive sleep apnea hypopnea syndrome and inflammation in children / 解放军医学杂志

Objective To investigate the clinical efficacy of anti-inflammatory therapy (intranasal corticosteroids combined with oral leukotriene receptor antagonist) in pediatric mild to moderate obstructive sleep apnea hypopnea syndrome (OSAHS),and analyze the relationship between OSAHS and inflammation factors.Methods Fifty patients with mild to moderate OSAHS,diagnosed by polysomnography (PSG) during Jan.to Nov.2016,were enrolled in present study.The patients' medical history,data of special physical examination,paryngorhinoscopy,PSG and OSA-18 questionnaire were collected.Patients received the therapy of intranasal corticosteroids combined with oral leukotriene receptor antagonist for 12 weeks.Special physical examination,paryngorhinoscopy,PSG and OSA-18 questionnaire were reviewed and the data before and after treatment were compared.Results Of the 50 subjects,37 were with mild OSAHS and 13 with moderate OSAHS.A total of 19 cases (38％) were cured including 17 mild OSAHS and 2 moderate cases.Other 19 cases (38％) got therapeutic effect but not be cured.Twelve cases (24％) were invalid or aggravated.There were 10 patients (20％) who received surgical treatment after drug treatment.The average values of obstructive apnea index (OAI) and mixed apnea index (MAI) decreased significantly in mild group and only OAI decreased in moderate group.After treatment,the average volumes of adenoids and tonsils were significantly reduced in mild OSAHS children but not in moderate OSAHS children.The OSA-18 questionnaire score declined only in mild group.No obvious correlation existed between the change of tonsil volume and the parameters of PSG.Conclusion Anti-inflammatory therapy of intranasal corticosteroids combined with oral leukotriene receptor antagonist may obviously reduce the volumes of adenoids and tonsils,improve the PSG indexes and the life quality of OSAHS patients,especially for those children with mild OSAHS.

Identification of Bx02 Alleles and Genetic Analysis of the Involved Ancestry / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To identify the genotypes of the blood sample whose blood grouping showed discrepancies and study the ABO alleles' molecular characteristics of the involved ancestry.</p><p><b>METHODS</b>Blood samples were preliminary genotyped by PCR-SSP. Complete exon 6 and 7 in the ABO genes were amplified by PCR and the PCR products were directly sequenced and cloning sequenced to identify its genotype.</p><p><b>RESULTS</b>Sequence analysis indicated that 3 samples of the family had an nt905A>G mutation in the B gene compared with ABO*B101. Combined with the serological results, the propositus could be typed as Bx02/O102.</p><p><b>CONCLUSION</b>DNA sequencing analysis is able to identify the serological phenotype samples that forward and reverse group methods were incongruous.</p>

The interactions among impact factors affecting 131I treatment efficacy of Graves′ disease / 中华核医学杂志

Objective To evaluate the possible interactions among different impact factors possibly affecting the treatment efficacy of 131I in Graves′ disease (GD). Methods Six hundred and thirty two GD patients that had been treated by 131I, with or without antithyroid drugs (ATD), were included in this study. The impact factors were pre-defined as age (x1), sex (x2), mass of thyroid (x3), course of disease (x4), initial symptom (x5), condition of disease (x6), ATD treatment duration (x7), effective half life time (x8), maximum 131I uptake rate (x9), total dose of 131I (x10), dose of 131I per gram of thyroid (x11), TRAb (x12), TSI (x13), TgAb (x14), and thyroid microsomal antibody(TMAb) level(x15). Interactions among different impact factors were studied by t-test, χ2 test and multi-variant logistic regression. Results Age, mass of thyroid, ATD treatment duration, maximum 131I uptake rate, dose of 131I per gram of thyroid tissue and TSI level were identified as independent impact factors affecting the 131I treatment efficacy on GD (χ2=6.908, t=-4.063, χ2=13.558, t=-2.553, t=4.528, χ2=9.716, all P0.05; F=2.928, 1.992, 2.629, 2.215, all P<0.05), which indicated that the treatment efficacy with co-existing multiple factors was not equal to simple summation of single factors. Conclusions The interactions among multiple factors can cause indi-rect effect on 131I treatment, which might guide the prescription of 131I dosage for GD treatment.
