RESUMEN
Alzheimer's disease is a common neuro-degenerative disease.The clinical diagnosis mainly depends on the patient's complaint,the score of mini-mental state examination and Montreal cognitive assessment scale,and the comprehensive judgment of MRI and other imaging examinations.Retina is homologous to brain tissue,and their vascular systems have similar physiological characteristics to small blood vessels in the brain.Numerous studies found that the thickness of retinal nerve fiber layer,visual function,retinal blood vessels and retinal oxygen saturation were changed in AD patients to different degrees.To explore the formation mechanism and significance of ocular fundus changes in AD patients will be helpful to select specific,sensitive and simple methods for early observation and evaluation of AD.

RESUMEN
Objective To study the role of transversus abdominis in lumbar spine stability,and to find a way to assess the abdominal muscles function.Methods 15 healthy subjects performed rapid arm flexion,abduction,and exten- sion.Electromyographic(EMG)activity of transversus abdominis,rectus abdominis,obliquus externus abdominis, obliquus internus abdominis and deltoid was evaluated with surface electrodes,latency between onset of the abdominal muscles and of the deltoid was calculated.Results The transversus abdominis invariably contracted before the deltoid and the other abdominal muscles,except the obliquus internus abdominis during arm extension.Conclusion(1)It's an effective way that latency between onset of abdominal muscles and of deltoid is used to assess the abdominal muscles function with arm movement as a factor of influencing the balance of spine.(2)Transversus abdominis,as deeper mus- cles acting earlier with all movements play an important role in maintaining the stability of lumbar spine.
RESUMEN
BACKGROUND: With the development of China, quality of life (QOL) is getting more and more attention, however, there are few studies on QOL, especially in Mainland China.OBJECTIVE: To observe the situation of combinative application of Functional Independence Measure (FIM) and QOL assessment in rehabilitation clinical practice.DESIGN: Case analysis.SETTING: Zhongshan Hospital of Fudan University.PARTICIPANTS: Totally 83 rehabilitation patients selected from Shanghai Zhongshan Hospital from January to December 2003,consenting to take part in the study, were divided into 4 groups: bone & joint rehabilitation(n=42), stroke rehabilitation (n=17), internal medicine (n=15), and cancer rehabilitation (n=9).METHODS: Every patient carried out functional independence assessment and quality of life measurement within 24 hours of admission. FIM was adopted for functional independence assessment which included 13 items of motor (ranged from 13 to 91 points) and 5 items of cognition (ranged from 5to 35 points), and FAQ for quality of life included making telephone call,self-care economy, shopping, using vehicle, housework, jobs, entertainment,etc. with 100 in total. The author performed all the assessment.MAIN OUTCOME MEASURES: Every patient carried out FIM and FAQ assessment after admission and discharge.RESULTS: All data of totally 83 patients entered the final analysis. [1]The average age and length of hospital stay in stroke group were higher than those in other groups (P ＜ 0.01). [2] FIM motor and cognitive scores in stroke group were higher at discharge than those at admission (5.276,3.624;6.200,5.941,P ＜ 0.01), but scores of functional activity were lower at discharge than those at admission (1.253, 1.547, P ＜ 0.01). [3]In bone joint group, the FIM cognitive scores were coincidence in general, while motor scores were higher at discharge than those at admission (6.220,5.388, P ＜ 0.01), but scores of functional activity were lower at discharge than those at admission (0.610, 0.912, P ＜ 0.01). [4] Only scores of functional activity in tumor group were lower at discharge than those at admission (0.722, 0.989, P ＜ 0.05). [5] All items in internal medicine group were coincidence in general (P ＞ 0.05).CONCLUSION: FAQ is more sensitive than FIM in rehabilitation practice, but cannot replace FIM, and should be used with FIM.
RESUMEN
BACKGROUND: In the early stage following spinal cord injury, a series of changes in metabolism and secretion take place, such as accelerated bone resorption and decreased bone formation. Determination of the biochemical markers of bone metabolism early after spinal cord injury may help understand the metabolic changes and facilitate risk evaluation for osteoporosis on such occasion.OBJECTIVE: To study the earlychanges of bone mass and bone metabolism indices in guinea pigs with spinal cord injury and evaluate the impact of spinal cord injury on bone metabolism.DESIGN: Randomly controlled animal experiment. SETTING: Department of Rehabilitation Medicine, Zhongshan Hospital of Fudan UniversityMATERIALS: The experiment was conducted in the Institute of Rehabilitation Medicine, Zhongshan Hospital of Fudan University in March 2004. Twenty-three male guinea pigs with body weight of 427-710 g (averaging 570 g) were provided by the Experimental Animal Center,Zhongshan Hospital of Fudan University and divided into experimental group (n=10) and normal control group (n=13). All the guinea pigs were kept under the same environment and fed with standard food for two weeks.METHODS: Small microsurgery scissors was used to induce a 1.5-mm transverse incision of the spinal cord, with the bleeding carefully managed and the wound closed. Thirty minutes after surgery, the guinea pigs recovered consciousness with bilateral lower limb paralysis (hypertonic paraplegia) and loss of superficial and deep sensations, but without urinary and fecal incontinence. The animals in the control group had sham operation. After housing in the same environment with standard food for 2 weeks, urine,serum and shinbone samples were collected from the animals for measurement of serum bone alkaline phosphatase (BALP), urinary pyridinoline (Pyd)/creatinine (Cr) and Ca/Cr. t test and H test were used for comparison of the samples between the two groups.parison of biochemical markers for bone formation between the two groups.RESULTS: Ten animals were analyzed in each group. No significant difference was observed in the BMD and bone dry weight between the two groups (P ＞ 0.05), but the bone ash weight of experimental group was remarkably lower than that of the control group [(0.284±0.050) vs (0.361±0.064) mg, t=3.254, P ＜ 0.05). The experimental group had significantly lower serum BALP than the control group [(0.640±0.240)vs (1.328±0.606) U/L, H=9.499, P ＜ 0.05), but higher urinary Pyd/Cr [(0.206±0.080) vs (0.117±0.037), P ＜ 0.01) and Ca/Cr [(0.003±0.003)vs (0.002±0.002), P ＜ 0.05] than the control group (H=9.676, 4.124,P ＜ 0.05).CONCLUSION: After the spinal cord injury, bone resorption remarkably increases and the function of the osteoblasts is inhibited. Bone metabolic abnormalities can occur in the early stage of spinal cord injury, and the biochemical indices for bone metabolism are sensitive in evaluating the risks for osteoporosis after spinal cord injury.
RESUMEN
Objective To examine the morphological changes in the cervical intervertebral foramen during axial rotation of cervical spine and explore its clinical significance for the diagnosis and treatment of cervical degenerative disease. Methods Ten healthy volunteers (5 male, 5 female) were subjected to transectional scan by multislice spiral computed tomography of cervical spine from the upper edge of C 3 vertebra to the lower edge of C 7 vertebra. On the 45 degree oblique reconstructions of C 3～4, C 4～5, C 5～6 and C 6～7 intervertebral foramina, four parameters were measured, including foraminal height, foraminal width (both superior and inferior), and cross-sectional area of the foramen. Statistic analyses were performed to examine the morphological changes in the cervical intervertebral foramen. Results It was found that the foraminal cross-sectional area was decreased on the side of rotation,and increased on the opposite side of rotation. Significant correlation was revealed between the variation rate of the C 3～4 intervertebral foramen cross-sectional area and the rotational degree between C 3 and C 4. Conclusion Morphologic changes were found in the cervical intervertebral foramen due to axial rotation. The correlation between the cross-sectional foraminal areas with the degrees of rotation of the vertebrae was statistically significant. The results of the test have the clinical significance on the prevention, diagnosis and treatment of the cervical degenerative diseases, especially of the radiculopathy.
