Objective To improve the three-dimensional gait and walking function of hemiplegic patients and enhance their quality of life through training with an end-driven lower limb rehabilitation robot.Methods Seventy elderly stroke patients with hemiplegia were enrolled and randomly divided into control group(n=35)and observation group(n=35).The patients in control group received conventional rehabilitation therapy after their conditions were stable,while the patients in observation group were trained by therapists with an end-driven lower limb rehabilitation robot besides the same treatment as control group.The rehabilitation efficacy was analyzed in terms of National Institute of Health Stroke Scale(NIHSS)score,Barthel Index(BI)score,Berg Balance Scale(BBS)score,Fugl-Meyer Assessment:Lower Extremity(FMA-LE),three-dimensional gait and satisfaction with nursing care.Results Before intervention,there was no significant difference between two groups in NIHSS score,BI score,BBS score,FMA-LE score,gait spatiotemporal parameters,gait temporal phase parameters,and ranges of motion of lower limb joints(P>0.05).After intervention,NIHSS score decreased,while BI score,BBS score and FMA-LE score increased in both groups(P<0.05),and the improvements were more obvious in observation group than in control group(P<0.05).The interventions in both groups increased step speed,step frequency and stride length,while reducing step width(P<0.05),with more significant improvements observed in observation group than in control group(P<0.05).Compared with those before intervention,the percentage of support period of the affected lower limb increased,and the ratio of the support period of the healthy side to that of the affected side and the percentage of double support period decreased(P<0.05),and these indexes were improved more prominent in observation group(P<0.05).The ranges of motion of lower limb joints in both groups were significantly greater than those before intervention(P<0.05),with greater ranges of motion in observation group than in control group(P<0.05).The total satisfaction with nursing care in observation group was higher than that in control group(97.14%vs 82.86%,P<0.05).Conclusion End-driven lower limb rehabilitation robot-assisted training can further improve the neurological function,lower limb function and balance ability in hemiplegic patients,with high patient satisfaction.The rehabilitation efficacy can be objectively assessed through three-dimensional gait analysis.

Objective: Kawasaki disease (KD) is the most common autoimmune vasculitis syndrome in children, which supposed be a complex polygenic disorder. Interleukin-17 (IL-17) is a member of the pro-inflammatory cytokine family, which has a strong pro-inflammatory effect and can participate in various acute and chronic inflammatory responses. This study aims to investigate the relationship between the single-nucleotide polymorphism (SNP) locus rs3819025 in the IL-17A gene and the susceptibility to KD. Methods: A total of 120 patients with KD who met the diagnostic criteria (the KD group) and 120 healthy children (the control group) were enrolled retrospectively in this study. Polymerase chain reaction (PCR) and DNA direct sequencing were used to detect the SNPs of children in the 2 groups. Results: The frequencies of GG, GA, and AA genotypes of rs3819025 locus in the IL-17A gene in the KD group were 82.5％, 17.5％, and 0, respectively, and the frequencies of GG, GA, and AA genotypes in the control group were 72.5％, 22.5％, and 5.0％, respectively. There were significant differences in both genotype (χ2=7.524, P=0.023). The allele frequencies G and A of rs3819025 locus in the KD group were 91.25％ and 8.75％, respectively, while those in the control group were 83.75％ and 16.25％, respectively. There was significant difference between the 2 groups (χ2=6.171, P=0.013). The distribution frequencies of GG or GA genotype and G or A allele were 88.46％ or 11.54％ and 94.23％ or 5.77％ in the KD group with coronary artery lesion, respectively. The distribution frequencies of GG or GA genotype and G or A allele were 78.72％ or 21.28％ and 89.36％ or 10.64％ in the KD group without coronary artery lesion, respectively. There were no significant differences in genotype and allele frequencies of rs3819025 between the KD with coronary artery lesion group and the KD group without coronary artery lesion (both P> 0.05). Besides, children with the allele A had a 2.023 times higher risk of KD than those without the allele A (χ2=6.171, P=0.013; OR=2.023, 95％ CI 1.151 to 3.557). Conclusions: The locus rs3819025 in the IL-17A gene is associated with the pathogenesis of KD. The allele A of the locus rs3819025 in the IL-17A gene may be a risk factor for KD.
