Objective To evaluate the effect of combination transfer pump and single blood pump to 32 cases of renal failure patient who need blood purification therapy.Methods The combination transfer pump and single blood pump were used.According to the clinical requirement,the parameters of transfer pump were set such as therapy time,replacement liquid flow rate,dialysate flow rate,temperature of warmer and filtrate flow rate,etc.Results 32 patients with varying degrees of illness have been alleviated.Patients' acute left heart failure,water and electrolyte turbulences,acid intoxication and azotemia caused by liquid retention were corrected,which ensured a role for further treatment.Conclusion It is the functions of adjustable time and transfusion volume that are used in the combination transfer pump,the task of which is accomplished by several transfer pumps together.This method is easy to implement and can meet the clinical requirement largely without special CBP instrument.

Heat stroke (HS) is a life-threatening illness characterized by core body temperatures above 40 ℃ coupled with central nervous system (CNS) dysfunction, including delirium, convulsions, and/or coma. Its morbidity has increased dramatically in the past few decades. Multiple organ dysfunction syndrome (MODS) is not only the most serious complication of HS, but also the leading cause of deaths. Understanding the pathogenesis, characteristic and advancement pattern of MODS caused by HS will have a profound effect on the clinical treatment, research and mortality decrease. The pathogenesis, injury characteristic of each system and organ, and treatment methods were summarized in this review so as to deepen the clinical recognition of this disease.

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.

BACKGROUND: Human transforming growth factor-β1 gene can be used for gene therapy of the degeneration of intervertebral discs, but the key to the experiment is to construct its effective vector.OBJECTIVE: To determine whether or not adult degenerated intervertebrai disc cells cultured in vitro after transfected by eukaryotic expression vector can express the product of human transforming factor-βl, and to provide the experimental basis of gene therapy for intervertebral disc degeneration.DESIGN: Single sample experiment. SETTING: Traumatic Orthopedic Institute of Shandong Province and the Orthopedic Department of Weihai Municipal Hospital.MATERIALS: The experiment was conducted at the laboratory of Traumatic Orthopedic Institute of Shandong Province between October 1999and January 2001. Intervertebral disc samples were from the operated patients with protrusion of irtervertebral disc after the patients were informed.Sample 1 was intervertebral disc at L4/5 from a 30-year-old woman; sample 2 was intervertebral disc at L5/S1from a 30-year-old woman.METHODS: ① Culture of adult degenerated intervertebral disc cells:Samples ex vivo were taken back to the laboratory within 30 minutes; fibrous ring cells and myelin nucleus cells cultured primarily were collected.② Transfection: Cells were put in the 24-well culture plate with 5.5×105cells in each well. Constructed PCI-hTGF-β1 eukaryotic expression vector was used to perform transfection, then transfected PCI group and nontransfected group were set. ③ The expression product of cells transfected for 48 hours was determined with immunohistochemical staining method.MAIN OUTCOME MEASURES: Comparison of absorbance of the positive cell product of eukaryotic expression vector PCI-hTGF-β1 in the primary fibrous ring cells and myelin nucleus cells in each group.RESULTS: ① Sample 1: The absorbance of positive cell product of eukary otic expression vector PCI-hTGF-β1 in the primary fibrous ring cells and myelin nucleus cells was 3.49 and 3.69 times that in PCI group, and 3.55times that in non-transfected group. ② Sample 2: The absorbance of positive cell product of eukaryotic expression vector PCI-hTGF-31 in the primary fibrous ring cells and myelin nucleus cells was 3.56 and 3.46 times that in PCI group, and 3.43 times and 3.33 times that in non-transfected group.CONCLUSION: PCI-hTGF-31, as the effective eukaryotic expression vector in the transfection of transforming growth factor-31 gene to culture degenerated intervertebral disc cells in vitro, can transfect adult degenerated intervertebral disc cells cultured in vitro and obtain the high expression of human transforming growth factorβ1 gene.

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.

Objective To investigate the reliability of Assessment of Activities of Daily Living of Chinese Quadriplegics. Methods The scale was administered to 20 patients with quadriplegia twice within one week interval by the same rater, and was administered to the same patients by another rater within 2 days after the first assessment. Results The intraclass correlation coefficient (ICC) of the test-retest reliability was 0.994 (P<0.01); the ICC of the inter-observer reliability was 0.971 (P<0.01). Conclusion Assessment of Activities of Daily Living of Chinese Quadriplegics is an instrument with high test-retest reliability and inter-observer reliability.

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.
