Background Neurofilament 200 (NF200) is an indirect indicator of the specific distribution of axons.It reflects the condition of the maintenance of neuronal morphology.Whether NF200 is involved in the damage of the visual pathway after retinal ischemia reperfusion injury (RIRI) should be further examined.Objective The present study was to investigate the expression of NF200 in retinal ganglion cells (RGCs),lateral geniculate nucleus (LGN),superior colliculus and visual cortex following RIRI.Methods Forty SD rats were randomized into the RIRI 1-,2-,3-,4-,6-,8-week groups,sham operation group and control group.Acute intraocular hypertension was induced in the right eye by anterior chamber perfusion of normal saline solution for 60 minutes to elevate the intraocular pressure to 110 mmHg.The animals were sacrificed at different time points for the preparation of the retina,LGN,superior colliculus and visual cortex sections.The expression of NF200 in RGCs,LGN,superior colliculus and visual cortex was assayed by immunohistochemistry.Results The expression level (A value) of NF200 in the RGCs was significantly different among the 8 groups after reperfusion (F =78.855,P =0.000),and that in the 1-week group was significantly lower than in the control group (t =36.563,P＜0.01).In the RIRI 1-week group,the expression of NF200 in the contralateral LGN in the experimental group was significantly lower than that in the control group (t =6.483,P＜0.01).In the 4-week group and 6-week group,the expression of NF200 in the contralateral LGN was significantly higher than that in the control group (t =2.904,4.313,P＜0.01).One week after RIRI,the expression of NF200 in contralateral superior celliculus in the experimental group was significantly lower than that in the control group (t =2.966,P＜0.05),and in the 2-week group,the expression of NF200 in the contralateral superior colliculus was significantly higher than that in the control group (t =7.397,P＜0.01).In the 2-week group,3-week group and 4-week group,the expression of NF200 in bilateral visual cortex was significantly higher in the experimental group than that in the control group (contralateral ∶ t =18.728,18.213,15.088,P＜0.01 ; ipsilateral ∶ t =8.690,5.704,7.805,P＜0.01).Conclusions RIRI can induce axonal damage of RGCs,contralateral LGN,superior colliculus and bilateral visual cortex neurons.

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 evaluate MRI in the diagnosis of the bone contusion of the knee joint and its clinical significance.Methods Using special coil for knee joint,coronal,sagittal,axial and oblique sagittal plane scanning with fast spin-echo sequence(T_1WI,T_2WI,PDWI+FS)was performed on knee joint in 205 patients in three days after injury.According the distributing bone marrow edema and injury mechanism,bone contusion were classified five types as pivot shift injury,clip injury,dashboard injury, hyperextension injury and lateral patellar dislocation.Results One hundred and forty-five cases of the 205 patients were found bone marrow edema without fracture on X-ray films.Among them,pivot shift injury was found in 43 cases accompanied with anterior cruciate ligament rupture in 30 cases,tear of the posterior horn of the lateral or medial meniscus in 12 and tears of the medial collateral ligament in 8 cases;clip injury in 53 cases accompanied with anterior cruciate ligament rupture in 10 cases,tear of the posterior horn of the lateral or medial meniscus in 15 and tears of the medial collateral ligament in 38 cases;dashboard injury 40 cases accompanied with posterior cruciate ligament rupture in 16 cases,hyperextension injury 9 cases accompanied with anterior cruciate ligament rupture in 2 cases,posterior cruciate ligament rupture in 5 cases.No lateral patellar dislocation was found.Forty-eight of 145 patients had undergone arthroscopy, 43 cases(89.6%)of them were in accordance with MRI diagnosis.Bone contusion were defined as geographic regions of abnormal signal intensity,that is,low signal intensity in T_1-weighted images and high signal intensity in PD-weighted or T_2-weigeted images with fat saturation.Conclusion MRI can accurately display the location and area of bone contusion of the knee joint as well as its adjunctive structure injury and deduce their injury mechanism.MRI should be used routinely for knee trauma.

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.

Objective To retrospectively analyze the lower extremity deep vein thrombosis prevention in patients with spinal cord injury (SCI). Methods A total of 115 SCI patients in our department from April to May, 2015 were included. The clinical symptoms, lower limb deep vein ultrasonic testing, laboratory examination were collected to analyze the occurrence, prevention measures, the thrombus location and management of deep venous thrombosis (DVT) in lower limbs. Results Forty-three patients had thromboprophylaxis in other hospitals before admission, and 105 patients in our department after admission, in which, nine cases were with clinical symptoms in other hospitals and three cases in our department. No pulmonary embolism occurred in them. There was no significant difference in most laboratory index-es between patients with DVT and without DVT in lower limbs (P>0.05). Five patients were with DVT in lower limbs in 43 patients who had thromboprophylaxis, and four cases in 72 patients who did not have thromboprophylaxis. No relationship was found between thrombo-prophylaxis and DVT in lower limbs (χ2=0.663, P=0.415). Five patients were with DVT in lower limbs in 53 patients with complete SCI, and four cases in 59 patients with incomplete SCI. No relationship was found between the severity of SCI and DVT in lower limbs in other hospitals (χ2=0.028, P=0.867). Conclusion DVT in lower limbs could be also occurred in patients who accepted thromboprophylaxis. Labo-ratory indexes are inadequate for the prediction and diagnosis specificity of DVT in lower limbs.

There is autonomic nerve dysfunction after cervical spinal cord injury. Fluctuation of blood pressure and heart rate was found as orthostatic hypotension and bradycardia.

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.

Objective To explore correlative factors with rehabilitation outcomes in spinal cord injury (SCI). Methods 226 patients were reviewed. Results Rehabilitation outcomes did not correlated with sex, occupation, and education, but correlated with the time of rehabilitation intervention, complications, hospital costs, injury severity and injury segment. Conclusion The time of rehabilitation intervention, complications, hospital costs, injury severity and injury segment are main factors related with rehabilitation outcomes of patients with SCI.
