ABSTRACT
Objective Related factors of pediatric obstructive sleep apnea hypopnea syndrome (OSAHS) combined with attention deficit hyperactivity disorder (ADHD) were retrospectively analyzed in OSAHS children. Methods The research included 437 cases of children hospitalized for OSAHS from January, 2014 to December, 2014. All the cases were divided into OSAHS group and OSAHS combined with ADHD group, according to the presence or absence of ADHD. Patient's general conditions (gender, age, height, weight, allergic rhinitis history, tonsil grade and adenoid grade), OSA-18 quality of life score, intention-hyperactivity score, polysomnography parameter (apnea hypopnea index, lowest oxygen) were collected as variables. SPSS20.0 was used to perform statistical analyses.Results There were 437 cases in this research, 298 of them were males, and 139 of them were females. Of 437 patients, 147 had OSAHS combined with ADHD (33.64%). Higher apnea hypopnea index (P <0.01) and severer oxygen deflciency (P < 0.01) were found in OSAHS combined with ADHD group than those in OSAHA group. Five projects of OSA - 18 score of in OSAHS combined with ADHD group were all higher than those in OSAHS group (P <0.01).Conclusions The incidence of pediatric OSAHS combined with ADHD in this research was more than 30%. More OSAHS combined with ADHD were found in male children. The quality of life was lower in pediatric OSAHS combined with ADHD. Oxygen deflciency was suggested to be the most important risk factor of ADHD in pediatric OSAHS.
ABSTRACT
Objective To study the expression of MAGE-3 in colorectal cancer (CRC) with different differentiation grades. Method Immunohistochemical technique for MAGE-3 antigen was performed in paraffin embedded sections of 101 CRC specimens. The relationship between differentiation and Dukes classification of CRC and the expression of MAGE-3 antigen was analyzed. Result MAGE-3 was only expressed in tumor tissues with the total positive rate of 31.7%. The rate and intensity of MAGE-3 in poorly differentiated group were higher than that of the well differentiated group (P0.05). Conclusion MAGE-3 may be a specific molecular differentiation related marker of CRC. Its antigen may have potential use as a new peptide vaccine for immunotherapy for CRC.
ABSTRACT
The study of renal cell carcinoma(RCC) was made in immunohistochemical expression of keratin and vimemin in 40 cases. 17.5% (7/40) of routine formalin-fixed, paraffin sectioned RCC specimens expressed vimentin. From a surgical pathological point of view, therefore, vimentin positive could no longer exclude an epithelial neoplasm, such as RCC.
