Objective To investigate the correlation between FA value,ADC value and limb muscle strength score measured by magnetic resonance imaging in patients with ischemic stroke,aims to to analyze the clinical value of magnetic resonance imaging in limb muscle strength.Methods Twenty patients with acute cerebral infarction and treated from June 2015 to Junly 2016 were recruited from This hospital,and the simplified Fugl-Meyer motor function score was observed for all patients within 3 days.Tensor imaging examination was conducted to observe the distribution of nerve fiber bundles,FA value,ADC value changes.Results The FA value and ADC value of the infarct side were significantly different from those of the contralateral side(t=8.70,t=-18.70,P＜0.05);There were significant differences in FA value and ADC value between the infarcted ventricle hind limbs and the contralateral side of the infarcted ventricle(t=-5.16,t=-5.08,P＜0.05).The FA value of the infarcted ventral hind limbs had positive correlation with the simplified Fugl-Meyer motor function score(R=0.863,P=0.013).Conclusion FA value and ADC value of acute infarct and internal hindlimb are lower than FA value and ADC value of contralateral normal white matter.The FA value of internal capsule hind limbs is closely related to the simplified Fugl-Meyer motor function score.

Objective: To analyze the relationship between the serum levels of low density lipoprotein cholesterol (LDL-C) and achilles tendon thickness (ATT).
Methods: We studied 154 patients with high serum level of LDL-C (LDL-C≥3.37 mmol/L) from 2014-03 to 2015-03, the patients were at (18-75) years of age. According to《Guidelines on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults 2007》, the patients were divided into 2 groups:Borderline high LDL-C (3.3-4.12 mmol/L) group n=50 and High LDL-C (≥4.14 mmol/L) group, n=104;in addition, there was a Normal control group (LDL-C<3.37 mmol/L), n=51. ATT values were measured by standard digital radiography and the results were compared among 3 groups;the relationship between serum levels of LDL-C and ATT was studied.
Results: ATT levels in High LDL-C group (9.42 ± 3.63) mm was higher than Borderline high group (8.24±1.73) mm and Normal control group (6.05±0.28)mm, all P<0.05. The liner correlation coefifcient of serum level of LDL-C and the mean ATT was (r=0.346, P<0.001).
Conclusion: Our preliminary research showed that the higher serum level of LDL-C associated with thicker ATT, they had positive correlation. This phenomenon should be further conifrmed by large sample and multi-center investigation.
