Objective To observe the effects of substance P (SP), NK1 receptor antagonist and nitric oxide synthase (NOS) inhibitors on the secretion of nitric oxide (NO) and expression of inducible NOS (iNOS) by immortalized human keratinocyte line HaCaT. Methods The NO level in supernatant of cultured HaCaT cells was measured by nitrate reductase assay after treatment with different concentrations (10-9 to 10-6 mol/L) of SP, or the combination of SP (10-8 mol/L) and spantide (3×10-7 mol/L), aminoguanidine (10-7 mol/L), 7-nitroindazole (10-6 mol/L) or L-NAME (10-5 mol/L) for various durations. Reverse transcription-PCR was performed to measure the expression of iNOS mRNA in HaCaT cells incubated with SP of 10-8 mol/L for 1, 24 and 48 hours. Results The SP of 10-9 to 10-6 mol/L significantly induced the production of NO by HaCaT cells, and the highest level of NO was observed in HaCaT cells treated with SP of 10-8 mol/L. The synthesis of NO by HaCaT cells induced by SP was inhibited by Spantide of 3 × 10~7 mol/L at all time points (30 minutes, 1, 3, 6, 12, 24 hours, all P< 0.01), by L-NAME of 10-5 mol/L at 3 time points (30 minutes, 1, 24 hours) and by 7-nitroin-dazole of 10-6 mol/L at 2 time points (30 minutes, 1 hour, both P< 0.05), but not by aminoguanidine of 10-7 mol/L at any time point (all P > 0.05). After treatment with SP of 10-8 mol/L, the relative mRNA expression of iNOS was 0.199 ± 0.018 and 0.516 ± 0.030 at 24 and 48 hours, respectively, and there was a statistical difference between the two time points (P < 0.01). Conclusions SP can reinforce the secretion of NO by HaCaT cells via NK1 receptor activation, but iNOS is unlikely to be the primary origin of NO secreted by HaCaT cells induced by SP.

Objective To observe the effect of static balance test and training equipment on the equilibrium function in children with spastic diplegia.Methods 24 children with spastic diplegia were treated with visual feedback balance training besides routine rehabilitation training.All cases were assessed with Berg Balance Scale(BBS) and the static balance test and training equipment when eyes opened and closed,before and after the 8-week training.Results After the 8 week-training,the BBS scores of all children were higher than that before training(P<0.05).In the segment of the static balance test,fall index,weight distribution index and stability index decreased significantly(P<0.05～0.01).Conclusion The equilibrium function of the children with cerebral palsy can be assessed and pertinent training can be performed with balance equipment.

Objective To explore the surface electromyography (sEMG) assist for the rehabilitation training for children with cerebral palsy. Methods 60 children with spastic diplegia were divided into treatment group (n=30) and control group (n=30). All the children received comprehensive rehabilitation, while the rehabilitation program were designed with the assist of sEMG in the treatment group. They were assessed with Gross Motor Function Measure (GMFM) before and 3 months after rehabilitation. Results There was no statistically improvement in dimension A, B, and C of GMFM (P>0.05), but was in the total score and the dimension D and E (P<0.0001). There was no statistical difference in dimension A, B, and C between 2 groups (P>0.05), but was in the total score and the dimension D and E (P<0.01) after rehabilitation. Conclusion The sEMG might be helpful for the rehabilitation for children with cerebral palsy.

Objective:To examine the expression of CLC-3 in colorectal tissues and the effect of CLC-3 on the viability and invasion of colorectal cancer (CRC) SW480 and SW620 cells. Methods:The mRNA levels of CLC-3 in CRC cell lines were determined by RT-PCR. CLC-3 expression was inhibited by adding DIDS or NPPB to the CRC cells. Subsequently, cell viability and invasion were assessed by CCK-8 assay and Transwell assay, respectively. In addition, the effects of DIDS and NPPB on the Wnt orβ-catenin signaling pathways were de-termined by Western blot analysis. Results:The mRNA level of CLC-3 was remarkably increased in the CRC tissues compared with that in normal colorectal tissues (P<0.05) and was positively correlated with the T stage of CRC. The blockade of CLC-3 inhibited the viability and invasion of CRC cells (P<0.05). The expression ofβ-catenin, C-myc, cyclin D1, Ki-67, and survivin were evidently reduced by the in-hibition of CLC-3 (P<0.05). Conclusion:The inhibition of CLC-3 decreases the cell viability and invasion of CRC cells by reducing the ex-pression of the proteins related to the Wnt orβ-catenin signaling pathway.
