Objective:To observe and analyze the abnormal gait characteristics and lower limb kinematic chain in patients with bilateral moderate-to-severe hallux valgus(HV)during adaptive walking.Method:From September 2022 to August 2023,33 patients with moderate-and-severe HV were selected from the department of arthrology,Wangjing Hospital,Chinese Academy of Traditional Chinese Medicine and en-rolled in the observation group.A group of 29 healthy subjects were matched and enrolled in the control group.DC-G-150-F2 three-dimensional gait analysis system was used to collect gait characteristics and lower limb motion chain of two groups during a 10m adaptive walking test.Temporal-spatial gait parameters and ki-nematic changes in the hip,knee,and ankle joints were observed and analyzed.Result:The gait time-space parameters of left and right support phase,total double support phase,left lateral foot deviation angle,step length,stride length and pace in the observation group were significantly lower than those in the control group(P＜0.05).In contrast,the time-space parameters of left and right swing phase and stride frequency in the observation group were significantly higher than those in the control group(P＜0.05).The two groups had no significant difference in right lateral foot deviation angle and step width(P＞0.05).The range of flexion and extension of the right hip joint,rotation of the left hip joint,rotation of the left and right knee joint and flexion and extension of the left and right ankle joint in the observation group were significantly lower than those in the control group(P＜0.05).There were no significant differences be-tween the two groups in the range of motion of left hip flexion and extension,right hip rotation,left versus right hip spreading,left versus right knee flexion and extension,and left versus right ankle rotation(P＞0.05).However,the range of motion of right hip rotation and right knee flexion and extension was lower than that of the control subjects(P=0.084,P=0.093).Conclusion:Gait changes in patients with bilateral moderate-to-severe bunions are characterized by shortened sin-gle and double support phases,prolonged swing phase,increased step frequency,reduced step length and stride length,and a"broken stride and slow catching up"walking pattern.The range of motion of each lower limb joint in the sagittal plane and horizontal plane is reduced,resulting in a rigid and twisted state through-out the lower limb kinematic chain.

Objective:To compare the clinical efficacy of a fixed exoskeleton robot with that of an exoskeleton walker in training the balance of stroke survivors in the subacute stage.Methods:Thirty persons with subacute stroke were divided at random into a fixed robot group (15 cases) and a walking robot group (15 cases). In addition to conventional rehabilitation treatment, the fixed robot group underwent daily 20-minute treadmill-based fixed exoskeleton robot training, 5 days a week for 2 weeks. The walking group was trained with an exoskeleton walking robot on the same schedule. Before and after the treatment, the Berg balance scale, the sitting modified functional stretch test (SMFRT), an isokinetic muscle strength test and the modified Barthel index (MBI) were used to evaluate the subjects′ global balance, self-dynamic balance, knee proprioception and ability in the activities of daily living (ADL).Results:After the treatment, both groups′ average Berg score, SMFRT extension difference, proprioceptive absolute error angle in the affected knee and MBI had improved significantly. The average SMFRT extension difference after treatment in the walker group was then significantly better than the fixed robot group′s average. However, the fixed robot group′s proprioception in the affected knee joint was then significantly better, on average, than among the walking robot group.Conclusions:Both fixed exoskeleton robot training and exoskeleton walker training can improve the balance, proprioception and ADL ability after a stroke. The former better improves dynamic balance; the latter better improves proprioception in the affected knee joint.

Objective To systematically retrieve and integrate the best evidence of enteral and parenteral nutrition support in adult patients with severe bums.Methods 2 nursing master students who had studied evidence-based nursing systematically searched the clinical decisions,recommended practices,guidelines,expert consensuses,systematic reviews,evidence summaries and other evidences on enteral and parenteral nutrition support for adult patients with severe bums in domestic and foreign guideline networks,relevant institutional websites and databases.The retrieval time was from the establishment of the databases to April 2023.2 researchers who had obtained master's degrees and undergone systematic evidence-based training in Fudan University used the appraisal of guidelines for research and evaluation n and JBI critical appraisal tools to evaluate the methodological quality,and extracted and summarized the evidence according to the theme.Results A total of 28 articles were included,including l clinical decision,9 guidelines,3 expert consensuses,9 systematic reviews,and 6 evidence summaries.A total of 20 pieces of evidence were summarized from 6 aspects:nutritional risk screening and assessment,energy requirement calculation,timing and route of nutritional support,nutrient intake,nutritional support monitoring and effect evaluation.Conclusion The best evidence of enteral and parenteral nutrition support for adult patients with severe burns summarized in this study is more comprehensive and scientific.It is suggested that in clinical application,targeted screening should be carried out according to the promotion and hindering factors of evidence,so as to scientifically carry out nutritional support for adult patients with severe burns.

Objective:To analyze the optical coherence tomography (OCT) imaging characteristics in patients with Coats disease and their value in predicting macular fibrosis.Methods:A nested case-control study was performed.A total of 43 patients (43 eyes) diagnosed with Coats disease through color fundus photography, ocular B-scan ultrasonography, fundus fluorescein angiography, and spectral-domain OCT examination were enrolled from January 2008 to October 2021 at the Xijing Hospital.Among them, there were 40 males and 3 females, aged from 2 to 60 years old, with a median age of 13 years.Macular fibrosis was used as an indicator of poor prognosis, and patients were divided into two groups based on whether macular fibrosis occurred at the end of follow-up.The differences in OCT characteristics between two groups were compared and logistic regression analysis was used to identify the risk factors for macular fibrosis.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Xijing Hospital of Fourth Military Medical University (No.KY20202009-C-1).Results:The OCT clinical features of 43 cases of Coats disease included intraretinal hard exudates in 43 eyes (100%), subretinal fluid in 21 eyes (48.8%), macular cysts in 17 eyes (27.9%), subretinal exudates in 9 eyes (20.9%), anterior retinal hyperreflective dots in 7 eyes (16.3%), epiretinal membrane in 21 eyes (48.8%), and intraretinal fluid in 22 eyes (51.2%).In color fundus photos of 41 eyes, 38 eyes (93.0%) had hard exudates distributed in the posterior pole and 27 eyes (65.9%) had the mid-peripheral region.OCT examination showed that hard exudates were distributed in the inner nuclear layer in 35 eyes (81.4%) and the outer nuclear layer in 33 eyes (76.7%).Among 21 eyes with exudative retinal detachment detected by OCT, 9 eyes (42.9%) were detected by fundus photography and 18 eyes (85.7%) were detected by B-scan ultrasonography.The proportions of eyes with subretinal fluid and subretinal exudates were higher in the macular fibrosis group than in the non-macular fibrosis group, and the differences were statistically significant ( χ2=20.755, P<0.001; χ2=6.133, P=0.013).Logistic regression analysis showed that the presence of subretinal fluid was a risk factor for macular fibrosis (odds ratio=48.345, 95% confidence interval: 4.272-547.066, P=0.002). Conclusions:OCT examination can detect subretinal fluid, subretinal exudates, macular cysts, macular exudates, and hyperreflective spots in the retina of patients with Coats disease.Subretinal fluid is a risk factor for macular fibrosis.
