Objective Electric stimulation functional observation statistics (FES) were collected for elderly patients with cerebral apoplexy in search of any curative effect. Methods A total of 40 patients with cerebral apoplexy were divided randomly into a FES group of 20 cases and a control group of 20 cases. Both groups received the same routine rehabilitation training and basic drugs. The FES group was also treated using FES therapeutic apparatus for 30 min daily over 3 weeks (15 sessions). The control group received no electrical stimulation. Upper limb motor function, lower limb motor function, balanceand Barthel's index were evaluated. Results In the FES group, upper limb motor function was significantly improved after treatment, and significantly better compared with the control group. Lower limb motor function showed the same significant differences. Balance was also significantly better after treatment and significantly better than in the control group. Similar significant improvements were seen in terms of Barthel's index. Conclusions FES can improve the functional capacity of elderly patients with cerebral apoplexy hemiplegia and improve their ability in daily activities.

To establish vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8) as secretary biomarkers for cell growth on topographic substrates, we have evaluated the secretion and expression of these 2 factors by SH-SY5Y human neuroblastoma cells on poly-L-lactide (PLLA) micropillar arrayed topographic substrates. We fabricated topographic substrates with UV lithography, silicon etching and polydimethylsiloxane-based replica molding, and interfaced SH-SY5Y human neuroblastoma cells with both the topographic substrates and PLLA flat substrates. Cell morphology and spreading were examined with scanning electron microscopy. The secretion and mRNA expression of VEGF and IL-8 were evaluated with enzyme linked immunosorbent assay (ELISA) and real time qPCR, respectively, 24 hours after cell plating. We successfully achieved 4 topographic substrates with a nominal pillar diameter of 2 microm and 4 microm, and a nominal pillar spacing of 2 microm and 7 microm. We found that the secretion and mRNA expression of VEGF and/or IL-8 by SH-SY5Y cells on 2-2 microm (pillar diameter-spacing), 4-2 microm and 4-7 microm topographic substrates were upregulated in comparison to those by cells on PLLA flat substrate, 24 hours after cell plating. Furthermore, both cytokines were even more substantially upregulated on the 2-7 microm substrate than on the other 3 topographic substrates. Compared to those on PLLA flat substrate, cells on topographic substrates showed significant changes in morphology (spreading area, perimeter and roundness), and the increase in the secretion and mRNA expression of VEGF and IL-8 was accompanied with a decrease in cell spreading areas. These results provided evidence that pillar arrayed topography was an important microenvironmental factor in affecting VEGF and IL-8 expression or secretion, and VEGF and IL-8 might serve as important secretary biomarkers for growth on topographic substrates by SH-SY5Y cells.
