Job Accommodation of American is effective to ensure the equal employment of domestic disabilities. This paper introduced its legal basis, contents and procedures.

Assistive Technology Act of the USA is a very important law for the persons with disability in USA. The background of the Assistive Technology Act of the USA was reviewed and the guarantee of laws for the disabilities was discussed in the paper. From which, some theory and practice for special education of China can be obtained, and some experience and enlightenment for setting up related laws in China also can be worked out.

Objective Alzheimer's disease (AD) is the most common neurodegenerative disorder of aging.Identifying novel AD genetic risk factors is important for understanding its pathogenesis.Presenilin- 2 (PSEN2) is one of the causative genes for familial AD.Polymorphism of the promoter region of PSEN2 has recently been reported to be associated with sporadic AD in a Russian population.The purpose of this study was to determine whether AD is associated with the PSEN2 gene polymorphism in a case-control study.Methods We examined PSEN2 and ApoE genotypes of 160 patients with AD and an equal number of age- and sex-matched controls from the same community by using PCR-RFLP method.Statistical analyses included a Chi-square test for homogeneity and a Logistic regression analysis.Results Examination of PSEN2 genotypes revealed no statistically significant differences in the frequency of the+A/-A polymorphism when compared with the total sample of AD patients and control individuals (P=0.11). However,subgroup of ApoE 84 non-carriers suggested significant differences of the three genotypes of PSEN2 promoter between AD and controls (P=0.038).Logistic analyses indicated ApoE genotypes were related with AD,and after stratification by e4 allele,PSEN2 genotypes were related with AD of e4 non-carriers.In addition,there was no interaction between ApoE and PSEN2 gene.Conclusion The+A/-A polymorphism of PSEN2 promoter may be a minor genetic risk factor for sporadic AD,especially in the group of AD without ApoE ?4 allele.

The paper presented the methods and experiences of managing nursing posts in Beijing Friendship Hospital.As introduced in the paper,such measures as conversion of organizational structure,innovative nursing post setup,new training model,dynamic allocation of nursing manpower,and effective performance incentive mechanism,promoted better nursing quality and stabilized nursing team,achieving sustainable development of quality nursing service.

Objective To explore the relationship between the serum neuron-specific enolase(NSE) level and stroke region and size,the degree of neurological deficit and prognosis at acute stage of stroke.Methods The level of serum NSE was detected by ELISA in 96 stroke patients at acute stage,including 58 cases of cerebral infarction (CI),27 cases of intracerebral hemorrhage(ICH),11 cases of subarachnoid hemorrhage (SAH) and 25 normal controls(NC group).The relationship between the level of serum NSE and China Stroke Score (CSS),Barthel index(BI),score of Glasgow-Pittsburgh Coma Scale,lesions region and volume were analysed among the various stroke types groups.Results The levels of serum NSE in the stroke patients at acute stage were significantly higher than that in NC group (allP

Objective To investigate influences of nasal continuous positive airway pressure to sleep architecture of obstructive sleep apnea syndrome and the reason of daytime sleepiness. Methods 34 patients with severe OSAS were monitored with polysomnography (PSG) before and after nCPAP treatment. Results Apnea hypoventilation index (AHI) decreased and the lowest SaO2 increased and sleep architecture was improved in all patients. Conclusion The nCPAP therapy can effectively improve the disturbances of sleep architecture and respiratory parameters.

Objective:? N oxalo L ?,? diaminopropionic acid were isolated from the powder of red ginseng. its physiological characteristics were studied. Method:This material is obtained by CM Sephadex C 25 and FPLC MonoQ. We have examined the effect of ? N oxalo L ?,? diaminopropionic acid on contraction of artery of guinea pig. Result:When histamin and adrenalin do not exist, there is neither contraction nor relaxation. It can strengthen induction of contraction of artery of guinea pig, but it has no such effect on adrenalin. Besides, it doesn't induce plaque coagulation through adrenalin, ADP blood coagulation enzyme and collagen. It doesn't suppress the transformation from tension peptide of blood vessel to enzyme.Conclusion:Hemostatic effect of ? N oxalo L ?,? dlaminopropinomie acid may caused by vesseles contraction through promoting Histamine.

AIM:To prepare the Lyophiled Royal Jelly Soft Capsule and study its stability and Influential factors.METHODS:The suspending agent and processing method were optimized using sedimentation volume rate as the index.Soft capsules were prepared and product stability under high temperature and high humidity environment was studied according to the determination of the content of 10-HAD by HPLC.RESULTS:The finished product yield in pilot test was more than 90%,the soft capsule products stored in cold were stable,while those stored under room temperature or high temperature and high humidity were unstable with a noticeable decrease in quality.Water content in capsule shell affects the 10-HDA content of the finished product.CONCLUSION:The preparative process is feasible and the products should be storaged in cold enviroment.

Objective To study the chemical constituents of Helicia nilagirica. Methods The ethanol extract was seperated by petroleum ether, dichloromethane, and n-butanol in sequence, then isolated by silica gel column chromatography. The structures were identified and elucidated by physicochemical pro-(perties) and spectral analysis. Results Four compounds were isolated from the petroleum ether extract and identified as n-hexadecane acid (Ⅰ), ?-sitosterol (Ⅱ), ?-sitosterol-3-O-?-D-glucoside-6′-acetate (Ⅲ), and daucosterol (Ⅳ). Conclusion All the compounds are isolated from the plant for the first time. Compounds Ⅰ, Ⅲ, Ⅳ are isolated from the plants of Helicia Lour. for the first time, and compound Ⅲ is a new natural product.
