Objective To investigate the expression and clinical significance of lipoxin A4,leukotrienc C4,lipoxygenase-5 in peripheral blood of pregnant women with different types of severe preeclampsia.Methods Forty-five singleton pregnant women who accepted antenatal care and delivered in First Affiliated Hospital of Wenzhou Medical College were enrolled in this study from December 2010 to June 2011.All objects were divided into normal pregnancy group (n=20),early onset severe preeclampsia group (n=10) and late onset severe preeclampsia group (n=15).Enzymelinked immunosorbent assay was used to detect lipoxin A4 and leukotriene C4 levels in peripheral blood.The level of lipoxygenase-5 mRNA in white blood cells was detected by real time fluorescence quantitative reverse transcription-polymerase chain reaction.The differences of lipoxin A4,leukotriene C4 and lipoxygenase-5 mRNA among groups were compared by analysis of variance and LSD-t test;and correlations among their expressions were analyzed by linear regression.Results Lipoxin A4 level in early and late onset severe preeclampsia group was (355.3±116.0) pg/ml and (389.7±117.5) pg/ml,which were both significantly lower than that in normal pregnancy group [(555.0±139.8) pg/ml] (t=-4.03 and-3.77,P＜0.05 respectively).The leukotriene C4 level in early and lateonset severe preeclampsia and normal pregnaney group was (591.3±185.5) pg/ml,(510.3±197.1) pg/ml and (496.9 ± 158.8) pg/ml,no statistical difference were found (F=0.889,P＞0.05) ; neither did the expression of lipoxygenase 5 mRNA,which was 4.2± 1.9 in normal pregnancy group,4.8 ± 2.0 in early onset severe preeclampsia group and 4.4 ± 1.2 in late onset severe preeclampsia group (F=0.311,P＞0.05).There was no correlation among the levels of lipoxin A4,leukotriene C4 and lipoxygenase-5 mRNA in each group (P ＞ 0.05).Conclusions Early and remarkable decreasing of lipoxin A4 level might contribute to the development of early onset severe preeclampsia.

Objective To investigate the effects of locomotor training on improving locomotor function after spinal cord injury(SCI)and the mechanism of spinal cord plasticity.Methods A model of complete thoracic cord transection was established using 84 adult female rats divided into sham,SCI and treadmill training(BWSTT) groups.The hind limb locomotor function of all the rats was evaluated.The fluorescence intensities due to (EphA4),vesicular glutamate transporter 2(VGluT2)and EphA4/VGluT2 double-positive neurons in the ventromedial area of the anterior horn of the lumbar COrd were detected using immunofluorescence double labeling and laser confocal microscopy.Results The rats in the BWSTT group showed better functional recovery in their hind limbs than those in the SCI group.BWSTT was correlated with markedly increased EphA4.VGIuT2 and EphA4/VGluT2 intensities in the ventromedial area.Conclusion BWSTT improves hind limb locomotor function in rats with thoracic cord transections by elevating the expression of EphA4/VGluT2,promoting neuronal plasticity in the lumbar anterior horn.

Objective To analyze the epidemiological characteristics of pituitary apoplexy and investigate the changes and features of endocrine hormones caused by pituitary apoplexy.Methods A retrospective analysis of the clinical and laboratory data of pituitary tumor and pituitary apoplexy was carried out.Results (1) The incidence of pituitary apoplexy was 31.78％,patients were 15-75 (47.5 ± 11.7) year old,most patients were female.(2)Diabetes,coronary heart disease,menopausal hormone therapy,radiotherapy,surgery,and bromocriptine administration may be related to pituitary apoplexy.(3) There was high incidence of apoplexy in nonfunctioning adenoma.(4) According to the relationship between apoplexy and pituitary tumor,cases with pituitary apoplexy were divided into 5 types.(5) Pituitary apoplexy was associated with low serum creatinine,hypernatremia,hyperchloremia,hypoeosinophilia,and hypobasophilia.(6) 61.61％ of the patients had pituitary hormone deficiency,especially the GnH deficiency.(7)98.10％ of the patients were treated by surgery.Conclusion Pituitary apoplexy has its own clinical characteristics,and more attention should be paid in clinical practice.

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.

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.

Objective To compare the characteristics of traumatic and non-traumatic spinal cord injury (SCI). Methods 226 patientswere reviewed. Results 73.4% of patients were traumatic SCI, who aged (33.96± 12.18) years, younger than non-traumatic (43.98± 11.4)years; 65.4% were complete injury, more than non-traumatic 38.7%; stayed in hospital for (189.74±157.88) d, longer than non-traumatic(142.53±85.72) d; spent (55270.39±47967.59) yuan, more than non-traumatic (40838.94±34786.85) yuan. The score of activities of daily livingwhen discharged (ADL2) was (54.25±24.16), poorer than non-traumatic (74.88±25.61). Conclusion Trauma is the major cause of SCI.The patients with traumatic SCI were younger, stayed in hosptital for longer time, spent more for hospitalization, and with poor ADL2.
