Objective:To build murine asthma model with Dermatophagoides pteronyssinus. To compare the curative effects of the immunotherapy regimens with either Dermatophagoides pteronyssinus allergen extracts or a recombinant Derp2(rDerp2). To offer a novel thread for immunotherapy of allergic diseases.Methods:The BALB/c mice were divided into four groups randomly. They were: negative control, positive control, allergen extracts and rDerp2. Mice were sensitized by i.p. injection of mixture of allergen extracts and Al(OH)3 except the negative control,and were i.p. given a treatment with either allergen extracts or rDerp2 respectively, and then were i.n. given allergen extracts as a challenge. Negative control was treated by saline always. Assays for IgE,IgG1,IgG2a in serum,IL-4,IFN-? in BALF and SCCS were performed by ELISA. Total cell number and assorted cell number in BALF samples were determined. The lungs kept in 10% formalin were made into slices stained by HE in order to observe the pathologic changes in lungs.Results:Compared to the negative control, in the positive control the total cell number and the number of inflammatory cell in BALF were significantly increased, BALF eosinophil counts were significantly increased, neutrophils and eosinophils were the predominant BALF inflammatory; and the Th2 cytokine, e.g. IL-4, was the main cytokine in BALF and SCCS. Compared with the positive control, the allergic responses in the mice given relevant immunotherapy were obviously alleviated, and the predominant cytokine in BALF and SCCS was Th1 pattern, e.g. IFN-?.Conclusion:We established successfully the murine asthma model. Immunotherapy with Dermatophagoides pteronyssinus allergen extracts had better curative effects than immunotherapy with recombinant Derp2.

Objective To investigate the efficacy and mechanism of subcutaneously given recombinant Der p 2 entrapped PLGA nanoparticles(DEPN) on mouse model with allergic airway inflammation.Methods 40 BALB/c mice were randomly divided into 5 groups,group A(normal control) were treated with saline(100 ?l) all the time,groups B,C,D and E were sensitized intraperitoneally with crude dust mite extracts(10 ?g) and then subcutaneously treated respectively with PBS(100 ?l),2 mg empty PLGA(EP),100 ?g rDer p 2,and 2 mg DEPN(loaded with 100 ?g rDer p 2) for 3 times,once per day,followed by intranasal challenge of 50 ?g rDer p 2.One day post challenge,mice were sacrificed and bronchoalveolar lavage fluid(BALF) was collected.Number of the total cells and eosinophils was determined,and airway inflammation and mucus secretion were analyzed by haematoxylin and eosin(H&E) staining and periodic acid-Schiff(PAS) staining.Level of cytokines in the supernatant of splenocyte culture was assayed by ELISA.Level of rDer p 2 specific IgG2a and IgE in the sera was determined by ELISA.Results The lung histology showed development of eosinophil infiltration in the airway of mice in groups B and C.The lung inflammation and mucus secretion in groups D and E were significantly alleviated than that of groups B and C.Number of total cells(63.50?5.12) andeosinophils(15.32?3.04) in BALF decreased in group B.Compared with group B,the number of total cells in groups D(55.3?5.20) ? 104 /ml and E(41.00?4.91) ?104 /ml greatly decreased(P

The comprehensive and precise functional evaluation is imperative in finding the disabilities of patients with quadriplegia,and it is the basement of providing appropriate rehabilitation training.The predominant instruments which have been used to evaluate the functional capacity of the quadriplegics include Barthel Index,Functional Independence Measure,Quadriplegia Index of Function,a short-form of Quadriplegia Index of Function Scale and Spinal Cord Independence Measure.The purpose of this article is to introduce the characters of each instrument above in functional evaluation for quadriplegics and the comparison among them.

This article mainly introduced the basic strategy of rehabilitation of spinal cord injury,including maintaining and improving range of motor(ROM),enhancing the muscle strength,sitting and standing balance training,respiration training,application of splints and aids.The rehabilitation objectives and approaches of each level of spinal cord injuries were also involved.

The complications of spinal cord injury(SCI)affect not only the rehabilitation treatment,but also quality of the patients' living,even threaten to patients' life,including pressure sore,complications of urinary system and respiratory system,deep venous thrombosis,pulmonary embolism,spasm,pain,autonomic dysreflexia,osteoporosis,etc.The prevention and treatment of complications of SCI may be helpful to improve patients' health,and a premise of the rehabilitation.

As the manual muscle testing is not sensitive enough to reflect the change of muscle strength, more and more people begin to use isokinetic dynamometry and handheld dynamometer for quantitative tests of muscle strength measurement. This paper briefly introduced the history of clinical approaches of muscle strength measurement, compared the advantages and disadvantages of various quantitative mus-cle strength testing, on which the specific techniques of clinical muscle strength measurement were discussed.

Spinal cord injury(SCI)may result in tetraplegia or paraplegia,which is a great damage to the abilities of patients' daily living.There is no cure of SCI at present,and standard rehabilitation is an effective treatment method of SCI.It will help the SCI patients to develop their remaining function and potential function,prevent all kinds of complications,decrease the incidence of disabilities,improve their quality of life,shorten their stay in hospital and decrease the medical expenditure.The necessary premise of their reentry family and society is to complete the barrier free accessibilities of their housing and occupational training.

Collection of information on lower urinary tract function is very important for the management of individuals with spinal cord lesions. The purpose of the Lower Urinary Tract Function Basic Data Set for Spinal Cord Injury(SCI) individuals is to standardize the collection and reporting of a minimal amount of information on the lower urinary tract in daily practice in accordance with the purpose and vision of the International Spinal Cord Injury Data Sets. By studying and using the International Spinal Cord Injury Lower Urinary Tract Function Basic Data Set, it is helpful to standardize and unify the collection of information on lower urinary tract function of patients with spinal cord injury in our country and afford evidences to the treatment of urinary system.

Objective To investigate the epidemiology characteristics of spinal cord injury(SCI)in hospital.Methods1264 inpatients with SCI during April 1992～August 2006 were analyzed retrospectively.Results and Conclusion56.1% of the cases were 20～40 years old.Traffic trauma(44.3%)and fall injury(21.8%)were the main causes of SCI.The incidences of affected segments were:cervical segments 31.5%,thoracolumbar 28.1%,and thoracic 21.3%.56.7% were complete injury and 43.3% were incomplete.The most frequent complication of SCI were:urinary tract infection,pressure sore and bladder lithiasis.The expenditure of hospitalization was provided by oneself(52.5%),public medicalcare(33.1%),only 4.1% by hospitalization insurance.

Cardiovascular disorders of spinal cord injury (SCI) are among the most common causes of death in individuals with SCI. The International Spinal Cord Injury Cardiovascular Function Basic Data Set is introduced in order to standardize the collection and reporting of a minimal amount of information on cardiovascular function in daily practice. Moreover, this data set makes it possible to evaluate and compare results from various published studies on cardiovascular function after SCI. The technical terms in this data set are defined in particular in this article.
