Paroxysmal nocturnal haemoglobinuria ( PNH) is a clonal hematopoietic stem cell disease characterized by intravascular hemolytic anemia , pancytopenia and thrombosis .Although PNH is an non-malignant disease , its complications have very negative impacts on patient's quality of life .The most common serious complication is thrombosis formation .

ObjectiveTo analyze the relative influential factors of hearing rehabilitation of the deafened children with multichannel cochlear implant. Methods42 prelingually deafened children who accepted multichannel cochlear implant were evaluated with their hearing ability, hearing thresholds and talent level, while their family and usage of the multichannel cochlear were investigated. Results and ConclusionThe result shows that the factors influencing the hearing rehabilitation are the occupations of the parents, income of the family, the time between diagnosing deaf and the operation, the time after the cochlear implant operation and the talent level. The results of the logistic regression show that the deafened children can gain their hearing developing rapidly if they living in a family with high income, their mothers have accepted more education, and they accepted longer time of continuing hearing-aid, etc.

The quality and integrity of clinical trials and associated data are not only derived from accuracy of trial data analyses, but also closely embodied to the authenticity and integrity of those data and data documents as well as the compliant procedures obtaining those data and relevant files in the life cycle of clinical trials. The compliances of good clinical practices and standards suggest the reliability, complete and accuracy of data and data documents, which is constructing the convincible foundation of drug efficacy and safety validated via clinical trials. Therefore, the monitoring and auditing on clinical trials and associated data quality keep eyes on not only verifications of reliability and correctness on the data analytic outcomes, but also validation of science and compliance of the trial management procedure and documentations in the process of data collections.

Background The development of retinopathy of prematurity(ROP) is associated with many regulatory cytokines related to neovascularization;however,the retinal expression and regulated mechanism of stromal cell-derived factor-1 (SDF-1) in mouse model of oxygen-induced retinopathy (OIR) remain uncertain.Objective This study was to investigate the expression of SDF-1 in retina of mouse model of OIR.Methods Forty 7-day-old C57BL/6J mice were divided into OIR group and control group.In OIR group,20 mice were exposed to 75% oxygen for 5 days and then to room air for 5 days.In control group,20 mice were raised in room air.The expression of SDF-1 in retina of mice was studied by immunochemistry and quantified by real time reverse transcriptase polymerase chain reaction (RT-PCR).Results The positive immunohistochemical staining for SDF-1 was found mainly locating at the ganglion cell layer in 12-day-old mice of OIR group;the stronger positive immunohistochemical staining for SDF-1 was noted mainly locating at the ganglion cell layer,vascular endothelial cells of inner retina,neovascular endothelial cells in 17-day-old mice of OIR group;the delicate positive immunohistochemical staining for SDF-1 was both found mainly locating at the inner retina and being around the retinal vascular in 12-day-old mice of control group and 17-day-old mice of control group.The expression of SDF-1 mRNA in 17-day-old mice of OIR group was higher than that of 12-day-old mice of OIR group (t=8.072,P＜0.05)and 17-day-old mice of control group(t=10.026,P＜0.05),respectively.The expression of SDF-1 mRNA in 12-day-old mice of OIR group was lower than that of 12-day-old mice of control group (t=4.336,P＜0.05).Conclusion SDF-1 might improve the onset of retinal neovascularization of OIR.
