Objective To investigate the effects of serum levels of leptin, IGF-1, BDNF and inflammatory markers in patients with post-stroke depression(PSD). Methods By using Hamilton rating scale for depression (HAMD) ,46 patients with post-stroke depression were recruited and 50 patients without depression as the control group. Two weeks after the onset of stroke, serum levels of leptin, insulin growth factor(IGF-1), hs-CRP, intracellular adhesion molecule (ICAM-1) and brain-derived neurotrophic factors (BDNF) were measured by enzymelinked immunosorbent assay(ELISA). Results The levels of leptin and IGF-1 in patients with PSD were significantly higher than that of the control group (( 57.4 ± 14.32) ng/ml vs (17.53 ± 11.62) ng/ml, P = 0. 002;(120.86 ±28.66) ng/ml vs (66.5 ± 17.51) ng/ml, P=0. 004 respectively). The serum levels of leptin and IGFI were positively correlated with the HAMD score(r=0. 724, P＜0. 01; r=0. 641, P＜0. 01 respectively). There was no significant differences in the levels of hs-CRP((2.3 ±0.42) mg/dl vs (2.2 ± 0.28) mg/dl, P= 0. 767),ICAM-1 (( 182.6 ± 50.27) ng/ml vs (178.7 ± 51.14) ng/ml, P = 0. 812) and BDNF(( 25.8 ± 8.35) ng/ml vs (24.2 ±7.48)ng/ml, P = 0.580)in the two groups. Conclusion The serum levels of leptin and IGF-1 may be associated with post-stroke depression and may be the markers of PSD in the old stroke patients.

Objective To describe the characteristic MR findings in the brain in patients with amyotrophic lateral sclerosis (ALS), and to assess the diagnostic value of conventional MR imaging and fractional anisotropy (FA) of diffusion tensor imaging (DTI). Methods Conventional MR imaging was performed in 14 clinically proved ALS patients and 12 age-matched normal controls. Contrast enhanced MR images were acquired in 2 patients. Axial and coronal DTI scans were performed in 10 patients and 12 normal controls with SE-EPI sequence. The b value was 1 000 s/mm 2, the number of diffusion sensitive gradient direction was 25. For quantitative assessment of the corticospinal tract (CST), FA value of bilateral CST was measured at the level of posterior limb (PL) of the internal capsule (IC) and the cerebral peduncle of the midbrain, respectively, and statistical analysis was performed. Results Focal slight low signal intensity on T 1WI and high signal intensity (hyperintense to gray matter) on T 2WI was demonstrated in 6 ALS cases (42.9%) in bilateral PL of the IC, and the high signal was longitudinally continuous from the PL to the cerebral peduncle on T 2WI coronal plane, corresponding to the course of CST. In another 8 ALS cases (57.1%), the focal slight low signal intensity on T 1WI and slight high signal intensity (isointense to gray matter) on T 2WI was revealed in bilateral PL of the IC. No abnormal contrast enhancement was detected in the 2 cases. In control group, the focal slight low signal intensity on T 1WI and slight high signal intensity (isointense to gray matter) on T 2WI was demonstrated in all 12 subjects in bilateral PL of the IC. FA values of the patient group were significantly lower than that of the control group at the level of the PL of the IC (F=7.38, P
