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 determine whether normal-appearing cervical spinal cord in patients with amyotrophic lateral sclerosis (ALS) has abnormal changes based on the quantitative measurement in healthy volunteers. Methods Conventional MRI and axial DTI were obtained in 16 patients with ALS (ALS group) and 16 age-matched control subjects (normal group) . ADC, fractional anisotropy (FA) and relative anisotropy(RA)imagcs were obtained on workstation (AW4. 2). ROIs (5 mm × 5 mm) were placed in anterior funicalus, posterior funiculus, and bilateral lateral corticospinal tracts (LCTs), respectively, at the same slice (C3). Independent-sample t test was used for comparison of parameters between the two groups. Correlations between DTI parameters of ALS and ALS course, Norris score, and ALSFRS were carried out separately by Pearson correlation analysis. Results FA and RA values of bilateral LCTs were decreased significantly. FA/RA values of left LCT were 0.762±0.089 and 0.762±0.107 in ALS group, while they were 0.863±0.098 and 0.890±0.105 in control group, respectively. FA/RA values of right LCT were 0.751±0.065 and 0.772±0.082 in ALS group, and they were 0.843±0.118 and 0.863±0.134 in control group, respectively, they were decreased significantly (t = 2.575、4.195、2.246、2.218, P < 0.05). There were no significant differences (t = - 1.319, - 1.087, P > 0.05) between ADC values of left and right CSTs in ALS group [(0.744±0.162) × 10~(-3), (0.767±0.141) × 10-~(3) mm~2/s] and control group [(0.640±0.149) ×10~(-3), (0.643±0.168) ×10~(-3) mm~2/s)]. FA, RA and ADC values of ALS patients in anterior funiculus were 0.637±0.113, 0.622±0.138, (0.950±0.354)×10~(-3) mm~2/s, in control group they were 0.670±0.117, 0.656±0.136, (0.865±0.238) × 10~(-3) mm~2/s, there were no significant differences (t = 0.854, - 0.704, - 1.155,P > 0.05). FA, RA and ADC values of ALS patients in posterior funieulus were 0.886±0.073, 0.920±0.100, (0.613±0.137)×10~(-3) mm~2/s, in control group they were 0.906±0.078, 0.914±0.135, (0.636±0.224) × 10~(-3) mm~2/s, there were no significant differences (t = 1.655, - 0.148, - 1.360; P > 0.05). No significant correlation existed between FA and RA values and disease course, Norris and ALSFRS score (P > 0.05), in left and right LCTs. Conclusion DTI with SE-EPI technique is simple and sensitive to detect the pathological changes of the cervical spinal cord in ALS patients. DTI can reveal the abnormalities which are "normal appearing" on conventional T_2WI.

Objective To evaluate the usefulness of functional magnetic resonance imaging (fMRI) as a noninvasive method in recording the activities of the human brain as excited by low frequency current(LFC) stimulator. Methods The right common peroneal nerves of 6 healthy volunteers were stimulated with LFC (NMR-II stimulator). The activities of the brain were then recorded and evaluated during the scanning by the fMRI technique. Data obtained during the study were dealt with with the software SPM99. Results In both cerebral hemispheres, the area where the postcentral and superior temporal gyrus, inferior parietal lobule met were excited, and so were the operculum at both sides. Postcentral gyrus, superior parietal and paracentral lobule, and the precuneus in the left cerebral hemisphere, as well as the superior occipital gyrus and the superior parietal lobule in the right hemisphere,were involved as the excited areas. Conclusion fMRI is a useful tool for recording and evaluating the brain activities excited by LFC.

To observe the effect of pIgR on Salmonella Enteritidis induced inflammation in jejunum and ileum in Chicken,7 day Hyline chickens were taken orally with Salmonella Enteritidis (SE) and killed after 1 d,3 d,7 d and 14 d.The mRNA expression of Toll-like receptor 4(TLR4),MyD88,TRAF6,NF-κB and pIgR was detected by real-time RT-PCR and pIgR protein level was detected by Western blot.The results showed that TLR4 signaling pathway was activated and mR-NA level of the pIgR in jejunum and ileum was enhanced (P＜0.01) and protein level of the pIgR in jejunum and ileum was up-regulated by SE.The study proved that TLR4 signal pathway on mucosal cell surface of jejunum and ileum was activated and expression of pIgR was up-regulated and gut mucosal immunity of chicken was strenghtened.
