OBJECTIVE:To systematically evaluate the clinical effectiveness of rehabilitation robots in treating lower limb motor dysfunction in patients with cerebral palsy,and to compare the differences in therapeutic effects among different robots.METHODS:PubMed,Web of Science,Embase,Cochrane Library,CNKI,CBM,VIP and WanFang databases were searched to collect randomized controlled trials on rehabilitation robotics for the treatment of motor dysfunction in patients with cerebral palsy,published from database inception to April 10,2024.The main outcome indicators included muscle strength,muscle tension,balance function,step speed,step frequency,step length,walking endurance,lower limb motor function,and activities of daily living.The above indicators were coded according to the International Classification of Functioning,Disability and Health.Meta-analysis was performed to evaluate the clinical efficacy and compare the therapeutic efficacy of different rehabilitation robots.Literature search and screening were performed by two researchers,and the quality of the included literature was evaluated using the Cochrane 5.1.0 risk of bias assessment tool.Meta-analysis was performed using RevMan 5.4 software and Stata 16.0 software.RESULTS:(1)Fifteen articles were finally included,involving 512 patients with 260 in the experimental group and 252 in the control group.(2)The Meta-analysis results showed that rehabilitation robots could improve body structure and function[standardized mean difference=0.41,95%confidence interval(CI):0.24-0.58,P<0.05],activities(standardized mean difference=0.53,95%CI:0.41-0.65,P<0.05)and participation ability(mean difference=7.86,95%CI:1.54-14.18,P<0.05).In particular,the rehabilitation robot improved lower limb muscle strength,balance function,step speed,walking endurance,lower limb gross motor function,and activities of daily living in patients with cerebral palsy,but showed insignificant effects on step frequency,step length,and muscle tension.(3)The network Meta-analysis results showed that:step speed:Innowalkpro>Gait Trainer>Lokomat>3DCalt;6-minute walk test score:Gait Trainer>Lokomat>Lokohelp>Innowalkro;Gross Motor Function Measure-88D score:Lokohelp>Lokomat>KidGo>Innowalkpro>3DCalt;Gross Motor Function Measure-88E score:Lokomat>Lokohelp>KidGo>3DCalt>Innowalkpro.CONCLUSION:Based on the International Classification of Functioning,Disability,and Health,rehabilitation robot training can improve the lower limb motor function and activities of daily living in patients with cerebral palsy.The Innowalkpro robot was more effective in improving step speed;the Gait trainer robot was more effective in improving 6-minute walk test scores;the Lokohelp robot was more effective in improving Gross Motor Function Measure-88D zone scores;and the Lokomat robot was more effective in improving Gross Motor Function Measure-88E zone scores.

Objectives:To explore the urban-rural differences in the association between the Life's Essential 8(LE8)scores and the risk of new-onset cardiometabolic diseases(CMD)among adult Chinese.Methods:A total of 4 719 adults aged 18 years or older without CMD from the China Health and Nutrition Survey(CHNS)cohort from 2009 to 2015 were enrolled,including 1 909 in urban areas and 2 810 in rural areas.CMD included myocardial infarction,stroke,and diabetes.The LE8 score included diet,physical activity,sleep,nicotine exposure,body mass index(BMI),non-high-density lipoprotein cholesterol(non-HDL-C),blood glucose,and blood pressure.The score of each LE8 factor ranged from 0 to 100 points,and the average of the sum of the eight scores was the final score.The final LE8 score was divided into a low group(<67.5 points),a medium group(67.5-77.5 points),and a high group(>77.5 points)according to the tertile of the final LE8 score.There were 780,564,and 565 cases in the low,medium,and high LE8 score groups in urban areas,respectively.There were 838,934,and 1 038 cases in the low,medium,and high LE8 score groups in rural areas.The primary outcome was the number of participants newly diagnosed with diabetes,stroke,and/or myocardial infarction during the follow-up period.The Cox proportional hazards regression model was used to analyze the urban-rural difference in the association between LE8 and the risk of new-onset CMD.Results:The total cardiovascular health LE8 scores in rural areas was higher than that in urban residents(72.9 points vs.70.2 points,P<0.01).During the average follow-up period([5.86±0.74]years),there were 176 new cases of CMD,including 67 cases in urban areas and 109 cases in rural areas.Multivariate Cox analysis showed that in the fully adjusted model,compared with the urban-higher group,the rural-lower group(HR=1.65,95%CI:1.27-2.15,P=0.001)had the greatest increased risk of new CMD,followed by the urban-lower group(HR=1.49,95%CI:1.01-2.21,P=0.046),the rural-middle group(HR=1.42,95%CI:1.06-1.90,P=0.020),and the rural-higher group(HR=1.16,95%CI:1.01-1.33,P=0.032).Multivariable Cox regression results showed that in urban areas,compared with those with LE8 scores≥70 points,those with LE8 scores<70 points and with unfavorable BMI score(HR=2.70,95%CI:1.51～4.84,P<0.01),blood glucose scores(HR=2.09,95%CI:1.24-3.51,P<0.01),and blood pressure score(HR=3.73,95%CI:1.69-8.24,P<0.01)faced increased risk of CMD;in rural areas,compared with≥70 points group,<70 points group with unfavorable BMI score(HR=3.92,95%CI:2.43-6.30,P<0.01),non-HDL-C score(HR=2.96,95%CI:1.94-4.52,P<0.01),blood glucose score(HR=2.59,95%CI:1.71-3.94,P<0.01)and blood pressure score(HR=1.85,95%CI:1.18-2.92,P<0.01)faced increased risk of CMD.The risk of CMD associated with BMI,blood glucose,and non-HDL-C scores<70 points was higher in rural areas than in urban areas.Conclusions:Although rural residents have slightly higher LE8 scores than urban residents,the risk of CMD associated with lower LE8 scores is particularly significant in rural areas.Strengthening the monitoring and primary prevention of cardiovascular health among rural residents is of great significance to reduce the burden of CMD in China.

ObjectiveTo observe the effects of Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the Haizao Yuhutang （HYT） on oxidative stress in the liver of goiter rats under the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020. MethodA total of 128 male Wistar rats were randomly divided into a blank group， a model group， a euthyrox group （20 μg·kg^-1）， a HYT group （12.06 g·kg^-1）， a HYT without Sargassum （HYT-H） group （9.90 g·kg^-1）， a HYT without Glycyrrhizae Radix et Rhizoma （HYT-G） group （10.26 g·kg^-1）， a HYT without Sargassum and Glycyrrhizae Radix et Rhizoma （HYT-HG） group （8.10 g·kg^-1）， and a Sargassum and Glycyrrhizae Radix et Rhizoma （HG） group （3.96 g·kg^-1）. The blank group was given deionized water by gavage， and the others were given propylthiouracil （PTU） to replicate the goiter pathological model. Euthyrox was taken as a positive control drug， and the rest of the Chinese medicine groups were given the corresponding decoction by gavage， the material was collected 12 hours after the last dose. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， and the contents of superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， malondialdehyde （MDA）， reactive oxygen species （ROS） in liver tissue were detected in each group. The pathological changes in the liver were observed via hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to detect the mRNA expressions of Kelch-like Ech-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， p53 and Caspase-3 in liver tissues. Western blot was adopted to detect the protein expressions of Nrf2 and HO-1 in liver tissues in oxidative stress-related signaling pathways. ResultCompared with control group， the model group showed significantly increased serum ALT level and contents of MDA and ROS in liver tissues （P<0.05， P<0.01）， significantly reduced activities of SOD and GSH-Px in the liver （P<0.01）， significantly increased mRNA expression of Keap1 （P<0.01）， and significantly decreased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. Compared with the model group， the HYT group manifested significantly reduced serum levels of AST， ALT， and ALP （P<0.05， P<0.01）， significantly reduced contents of MDA and ROS in liver tissue （P<0.01）， significantly increased the activities of SOD and GSH-Px （P<0.01）， significantly decreased mRNA expressions of Keap1， p53， and Caspase-3 （P<0.01）， and significantly increased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. ConclusionUnder the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020， Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the HYT on oxidative stress in the liver of goiter rats had different effects. The HYT that contains Sargassum and Glycyrrhizae Radix et Rhizoma has a protective effect on the liver of goiter rats， and the effect is better than that of the HG group， the euthyrox group， and the incomplete groups. Its mechanism may be related to activating the Nrf2/HO-1 signaling pathway to alleviate liver oxidative stress and inhibiting the p53/Caspase-3 signaling pathway to reduce hepatocyte apoptosis.

OBJECTIVE:To systematically evaluate the efficacy of rehabilitation exoskeleton robots on the lower limb motor function of stroke patients using Meta-analysis and to compare the efficacy of different lower limb exoskeleton robots,so as to provide a theoretical basis for the scientific selection of suitable exoskeleton robots for patients with post-stroke lower limb motor dysfunction. METHODS:Computer searches of the Cochrane Library,PubMed,Web of Science,Embase,CNKI,VIP,and WanFang Data were conducted to collect randomized controlled clinical studies on exploring lower extremity rehabilitation exoskeleton robots to improve lower limb motor function in stroke patients published from database inception to November 2022.Two researchers conducted the literature search and screening.The quality of the included literature was evaluated using the Cochrane 5.1.0 risk of bias assessment tool and the Jadad scale.Meta-analysis was performed using RevMan 5.4 and Stata 17.0 software. RESULTS:(1)Finally 22 publications were included,involving 865 patients(n=436 in the test group and n=429 in the control group),and the Jadad score showed that all the included articles were of high quality.(2)Meta-analysis results showed that the exoskeleton robot significantly improved the Fugl-Meyer Assessment of Lower Extremity score(mean difference[MD]=2.63,95%confidence interval[CI]:1.87-3.38,P<0.05),Berg Balance Scale score(MD=3.62,95%CI:1.21-6.03,P<0.05),Timed Up and Go score(MD=-2.77,95%CI:-4.48 to-1.05,P<0.05)and step frequency score(MD=3.15,95%CI:1.57-4.72,P<0.05)in stroke patients compared with the control group.However,there was no significant improvement in the Functional Ambulation Category Scale score(MD=0.30,95%CI:-0.01 to 0.61,P>0.05)and 6-minute walk test score(MD=3.77,95%CI:-6.60 to 14.14,P>0.05).(3)Network Meta-analysis results showed that compared with the conventional rehabilitation therapy,both the level-walking exoskeleton(MD=10.23,95%CI:3.81-27.49,P<0.05)and the body-weight support exoskeleton(MD=33.66,95%CI:11.49-98.54,P<0.05)improved the Fugl-Meyer Assessment of Lower Extremity score.Compared with the conventional rehabilitation therapy,body-weight support exoskeleton significantly improved the Berg Balance Scale scores(MD=79.86,95%CI:2.34-2 725.99,P<0.05).In terms of Fugl-Meyer Assessment of Lower Extremity and Berg Balance Scale scores,the ranking results were body-weight support exoskeleton>level-walking exoskeleton>conventional rehabilitation therapy.Compared with the conventional rehabilitation therapy,level-walking exoskeleton significantly improved the Functional Ambulation Category Scale score(MD=1.38,95%CI:1.00-1.90,P<0.05)and body-weight support exoskeleton significantly improved the Timed Up and Go score(MD=0.07,95%CI:0.01-0.51,P<0.05).In terms of Functional Ambulation Category Scale and Timed Up and Go scores,the ranking results were level-walking exoskeleton>body-weight support exoskeleton>conventional rehabilitation therapy. CONCLUSION:Rehabilitation exoskeleton robots can improve balance,walking and activities of daily living in stroke patients,with body-weight support exoskeleton being more effective in improving lower limb motor function and balance and level walking exoskeleton being more effective in improving functional walking and transfer.

The ethics committee of organ transplantation technology and clinical application in a hospital has encountered some difficulties and typical cases in its review work and practice for many years. Sometimes, it is difficult to make a decision in these dilemmas. Based on the previous experience of the hospital in the ethical review of organ donation and transplantation, combined with two typical cases, this paper discussed and analyzed two review points of whether the voluntary unpaid donation and the principle of informed consent were met, and whether the risk-benefit ratio was reasonable, and put forward relevant ethical and legal countermeasure for further research by institutional ethics committees and other parties, in order to provide reference for discussing the practical problems and ethical confusion of ethical review of organ donation and transplantation.

Currently,the ethical review model for organ donation and transplantation in domestic hospitals is generally characterized by suddenness,unpredictability,tight time,difficulty in convening meetings and training committee members,as well as generally low quality and efficiency of ethical review,which cannot meet clinical needs and cause the waste of some scarce resources.The team of the Clinical Application Center of Human Organ Transplantation and the Ethics Committee of the First People's Hospital of Kunming combine more than 10 years of review practice experience,as well as continuously explore and optimize the ethical review process and operating procedures for organ donation and transplantation.The special application has been approved and jointly developed with Soochow University and the Medical Ethics Committee of Fujian Province to build a full-process information software system management platform for organ ethical review of donation and transplantation,giving the full play the advantages of the review information system in improving work efficiency and review quality,facilitating full-process information management,and conducting online training and learning for committee members,with a view to providing a specialized practical model for addressing the difficulties and challenges related to ethical review of human organ donation and transplantation.
