OBJECTIVETo analyze the factors in the non-operative treatment of cervical spinal cord injury without fracture or dislocation.

METHODSThe clinical data of 122 patients with cervical spinal cord injury without fracture or dislocation from January 2009 to December 2012 treated by non-operative treatment were retrospectively reviewed. There were 84 males and 38 females, aged from 18 to 83 years with an average of (52.37 +/- 13.27) years. The clinical features, such as age, gender, cause of injury, time from injury to treatment, ASIA grade of spine cord injury, MRI type of spine cord injury, range of spine cord injury, effective cervical spinal canal ratio, Pfirrmann grade of intervertebral disc herniation, segment of intervertebral disc herniation, intervertebral disc ligament complex injury, treatment of high-dose methyiprednisolone, were observed. Single factor and multiple factor Logistic regression analysis were used in the clinical data in order to analyze the influencing factors of above items to prognosis.

RESULTSFor univariate analysis, the factors such as MRI type of spine cord injury, extent of spine cord injury, effective cervical spinal canal ratio, Pfirrmann grade of intervertebral disc herniation, segment of intervertebral disc herniation, ASIA grade of spine cord injury, associated with prognosis (P < 0.05). Multiple linear regression analysis showed that the main prognostic factors including MRI type of spine cord injury, range of spine cord injury, effective cervical spinal canal ratio, Pfirrmann grade of intervertebral disc herniation, ASIA grade of spine cord injury according to its effective intension (P < 0.05).

CONCLUSIONThe main prognostic factors on non-operative treatment of cervical spinal cord injury without fracture or dislocation were MRI type and extent of spine cord injury, meanwhile, correlate with effective cervical spinal canal ratio, Pfirrmann grade of intervertebral disc herniation, ASIA grade of spine cord injury. It is deliberative to choose no-operative treatment, for it only refers to the patients with the mild localized edema type or no signal change of spinal cord in MRII. Operative treatment shoud be recommended for other patients.

Objective To compare the clinical effect of three different methods in treatment of premature.Methods 150 premature patients were randomly divided into three groups,50 cases for each group,received treatments with ritodrine,magnesium sulfate plus salbutamol,or magnesium sulfate alone respectively. The tensity of uterine contraction, the interval between drug administrations and the relief of uterine contraction, the accumulative drug using time, the elongated pregnancy durations were observed for the dertermination of effectiveness. Results The group treated with ritodrine, magnesium sulfate plus salbutamol or magnesium sulfate were effective in 94%, 78%,70% of patients of each group, and it showed that ritodrine was more effective than the combination and magnesium sulfate. The intervals of drug using and contraction relief were statistically different among three groups, (2. 16 ±0. 91)h,(4. 14 ± 1.07)h,(5.12 ± 1.45) h for each(all P ＜0.05).The cumulative drug using times were(7. 04 ±1. 16) d, (7.46 ± 1.20) d, (7.06 ± 2.78) d for three groups and proved not to be statistically significant ( all P ＞0. 05 ). The elongated pregnancy durations were (22.08 ± 7.32 ) d, ( 17.42 ± 5.85 ) d and ( 11.82 ± 5.04 ) d, and significantly different in three groups ( all P ＜ 0. 05 ). Conclusion The treatment of premature with ritodrine or the combination of magnesium sulfate and salbutamol was superior to using magnesium sulfate alone.

Objective To investigate the correlation between abnormal lipid metabolism and coronary artery lesions. Methods Two hundred and sixty seven patients were devided into the control group ( n =101) and the coronary heart disease (CHD) group ( n =166), which included single vessel lesion ( n =54), double vessel lesions ( n =68) and triple vessel lesions ( n =44) according to coronary angiography. At the same time the lipid components were examined and the ralationship between serum lipid level and coronary artery lesions were analysed. Results Compared with the control, the total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triglyceride (TG) level were significantly elevated while but high density lipoprotein cholesterol (HDL-C) was lowered in the CHD group. The severity of coronary lesions was increased with the elevation of TC, LDL-C, apolipoproteinB (ApoB), TC/HDL-C, LDL-C/HDL-C, and the reduction of HDL-C. There were significant differences in terms of lipid level beteewn the CHD group and the control. The analysis showed that TC/HDL-C and LDL-C/HDL-C were most directly correlated with the coronary artery lesions in the CHD group. Conclusion The results suggest that the severity of coronary artery lesions correlated with abnormal lipid metabolism, and LDL-C/HDL-C, TC/HDL-C are better indicators than other lipid components.

BACKGROUND: The recovery of activity of daily living (ADL) in hemiplegic patient is related to the recovery of motor function to certain extent. But the correlation between two aspects has not been determined yet over the past study.OBJECTIVE: To probe into the correlation between the motor function of upper and lower limbs and ADL of hemiplegic patients after cerebral apoplexy.DESIGN: Case analysis.SETTING: Department of Rehabilitation of First Affiliated Hospital of Nanjing Medical University.PARTICIPANTS: Thirty cases of hemiplegia of cerebral apoplexy were selected from inpatients of Department of Rehabilitation of Jiangsu People's Hospital from August 2002 to June 2003, of which, 20 cases were male and 10 cases were female, aged varied from 39 to 76 years.METHODS: Simplified Fugl-Meyer assessment of motor recovery (FMA)was used to evaluate the motor function of patient. Modified Barthel index assessment was used to evaluate ADL.MAIN OUTCOME MEASURES:① Simplified Fugl-Meyer assessment and modified Barthel index assessment.② Correlation between the motor function and ADL of hemiplegic patients after cerebral apoplexy.RESULTS: All of 30 cases entered result analysis.①The average result of general FMA was 40.96±32.04.The average result of motor function of upper limb was 21.78±22.87 and of low limb was 18.43±10.29.The average result of modified Barthel index assessment was 39.46±25.94. ② The correlative coefficient of general FMA and modified Barthel index assessment was 0.65, in which, the correlative coefficient of upper limb assessment and modified Barthel index assessment was 0.62 and that of lower limb assessment was 0.61.CONCLUSION: A certain correlation presents between motor function and ADL in hemiplegic patient and the influences of upper and lower limb motor functions are almost same to daily life activity.
