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.

Objective To study the microsurgical and anatomic structures of brachial plexus roots and vertebral canal to find the best approaches for reimplantation of avulsed brachial plexus ventral roots into the spinal cord.Methods On nineteen cervicothoracic spine specimens,the brachial plexus nerves were exposed along to intervertebral foramen,and the spinal cord and brachial plexus roots were exposed by excising the vertebral arch and sectioning the spinal dura mater.The anatomy of brachial plexus roots and vertebrae,and the relative positions of spinal cord segments to vertebral discs were measured and observed.Results The relative positions of spinal cord segments to vertebral discs are:C5-7 spinal cord segments face C3,4,C4,5 and C5,6 vertebral discs;and C8 and T1 spinal cord segments face C6 and C7 vertebrae.Based on the anatomic finding,four approaches were found out: the lateroventral approach,the lateral approach by enlarging intervertebral foramen,the laterodorsal approach and the lateral and dorsal combined approach.Conclusions The brachial plexus ventral roots can be best reimplanted into the spinal cord by the lateroventral approach and the lateral approach.Although the laterodorsal approach and the lateral and dorsal combined approach are not the best,they are less difficuh and dangerous.

Objective To study the effect of three kinds of disinfection liquid,namely chlorine dioxide,silver ion and BIOCIDE,on sterilization of Legionella pneumophila.Methods The suspended quantified disinfection test was conducted by using 7 type of Legionella p neumophila,0.5 ml of bacterial suspension and 4.5 ml disinfection liquid were mixed for certain period, the normal saline was used as the control.1.0 ml of the above liquid or its dilution was incubated with BCYE for 72 h in CO_2 and 35 ℃,the colony count and sterilization rate were calculated.Results The sterilization rate of chlorine dioxide was 6.04%,7.87% and 18.18% at the sterilization time of 0.5,1 and 2.5 h respectively.The sterilization rate of silver ion was 52.61%,99.46% and 99.80% at the time of 0.5,1,1.5 and 2.0 h respectively.As for BIOCIDE,the sterilization rate was 25.28%,93.62%,96.60% and 99.81% at the time of 0.5,1,1.5 and 2 h respectively.Conclusion Compared with chlorine dioxide,silver ion and biological disinfectant has a better sterilization effect on Legionella pneumophila.

Objective To evaluate the efficacy and safety of methotrexate(MTX)on the hip involve ment in patients with ankylosing spondylitis(AS).Methods Among the AS patients with hip joint involvement admitted to the department from 1999—2002,50 patients were treated with sulfasalazine(SSZ)(control group, CG)and 48 MTX(observation group,OG).One kind of NSAIDs was taken by the patients in both groups as the basic therapy.The treatment was maintained in both groups after being discharged.Patients were followed-up for three years.The observation parameters included symptoms,signs,Bath AS disease activity index(BASDAI), Bath AS functional index(BASFI),hip joint function score,the CT staging of hip joint involvement,serum in- flammation markers,laboratory tests and side effects.The data were analyzed with SPSS10.0 statistics software. Results At the 1st,2nd and 3rd year,44,38 and 32 cases in the OG and 45,38 and 31 cases in the CG were followed up respectively.During the three-year follow-up period,the hip joint function score of the OG was significantly higher than that of the CG(P
