ObjectiveTo investigate the effect of repetitive peripheral magnetic stimulation (rPMS) combined with upper limb intelligent robotic training on muscle tension, motor function and cortical excitability in children with unilateral spastic cerebral palsy (USCP). MethodsFrom March, 2023 to December, 2024, 90 children with USCP admitted to Children's Hospital of Soochow University were selected and randomly divided into control group (n = 30), rPMS group (n = 30) and combined group (n = 30). The control group received conventional occupational therapy. The rPMS group received rPMS intervention followed by conventional occupational therapy. The combined group received rPMS followed by upper limb intelligent robot training, for four weeks. Before and after treatment, muscle tension of biceps brachii was assessed using the modified Ashworth Scale (MAS); upper limb motor function was evaluated using the Fugl-Meyer Assessment-Upper Extremity (FMA-UE) and upper limb intelligent parameters; and cortical excitability was measured using transcranial magnetic stimulation (TMS), including resting motor threshold (RMT) and motor-evoked potential (MEP) amplitude of the affected hemisphere. ResultsAfter treatment, MAS grades improved in all groups (|Z| > 3.523, P < 0.001), and the improvement in the combined group was superior to that in the control group (P < 0.05). Significant intra-group (F > 65.21, P < 0.001), inter-group (F > 17.94, P < 0.001) and interaction effects (F > 5.36, P < 0.01) were observed in FMA-UE scores, upper limb intelligent parameters and TMS parameters. Post Hoc analysis showed that the combined group demonstrated significantly greater improvements in FMA-UE scores, upper limb intelligent parameters, and TMS parameters compared with both the control and rPMS groups (all P < 0.01). Except for FMA-UE scores, the rPMS group showed significantly greater improvements than the control group in upper limb intelligent parameters (mechanical feedback, trajectory, and range of motion) and TMS parameters (RMT and MEP amplitude) (P < 0.05). ConclusionrPMS combined with upper limb intelligent robotic training can reduce upper limb muscle tension, improve motor function, and enhance cortical excitability in children with USCP.

Objective To investigate the influence of the liver failing to convey and disperse on space navigation aging.Methods High and low neuroticism subjects screened by Eysenck personality questionnaire were included in liver failing to convey and disperse group and liver controlling conveyance and dispersion group,respectively.The two groups were then divided into youth and elderly groups based on age.Finally,spatial navigation task was conducted to record and analyze behavioral(reaction time and accuracy)and EEG data(amplitude and latency of P2 and N2 components)of all the four groups(30 subjects each group).Results Compared with liver controlling conveyance and dispersion group,the accuracy in subjects with liver failing to convey and disperse decreased significantly(P<0.001)and reaction time was prolonged significantly(P<0.05).The interaction effect between age and liver regulation status showed a marginal significant difference(P=0.078).The accuracy of elderly people was lower than that of youth people(P=0.002)for liver failing to convey and disperse subjects,while there was no significant difference between the two groups for subjects with liver controlling conveyance and dispersion.The P2 amplitude in the elderly group was significantly smaller than that in the youth group(P=0.027).The amplitude of P2 in group of liver failing to convey and disperse was significantly smaller than that in group of liver controlling conveyance and dispersion(P=0.042).The interaction effect of P2 amplitude between age and liver regulation status showed a marginal significance(P=0.073).For youth subjects,the P2 amplitude in group of liver controlling conveyance and dispersion was significantly larger than that in group of liver failing to convey and disperse(P=0.007),while there was no significant difference in P2 amplitude between the two groups for the elderly subjects.The N2 amplitude for tasks of allocentric frames of reference was significantly greater than that of egocentric frames of reference(P=0.024).Conclusion Liver failing to convey and disperse caused by long-term emotional disturbance accelerates spatial navigation aging,and selective attention feature inhibition disorder may be the underlying ERPs neuroelectrophysiological mechanism.

Objective To investigate the influence of the and mechanism of liver failing to convey and disperse on age-related changes in attentional search based on ERPs.Methods oddball attention search task was administrated to record and analyze behavioral and EEG data(N2pc、SPCN、N2pc-Ptc components)of 120 subjects.Results Compared with liver controlling conveyance and dispersion group,the accuracy in subjects with liver failing to convey and disperse decreased significantly(P<0.05).The elderly group had a lower accuracy(P<0.001)and a longer reaction time(P<0.001)compared to the young group.The N2pc amplitude in subjects with liver failing to convey and disperse was significantly greater than that in subjects with liver controlling conveyance and dispersion(P<0.05).The interaction effect of SPCN amplitude between age and liver failing to convey and disperse status was significant(P=0.024).And in the elderly group,SPCN amplitude in subjects with liver dysregulation was significantly smaller than that of liver controlling conveyance and dispersion(P=0.042).The N2pc-Ptc peak to peak amplitude interaction effect between age and liver regulation status was marginal significant(P=0.087),and in liver failing to convey and disperse group,N2pc-Ptc peak to peak amplitude of the elderly was significantly smaller than that of the young(P=0.008).Conclusion Attention search ability is impaired in the elderly with liver failing to convey and disperse,and the electrophysiological abnormalities,such as directed attention allocation,spatiotemporal dynamic cohesion and short-term memory maintenance,may be part of the mechanism.

Objective:To investigate the therapeutic effectiveness of ultrasound-guided percutaneous catheterization for continuous negative pressure drainage combined with polidocanol in treating large thyroid cysts.Method:Clinical data of 38 patients with large thyroid cysts who were treated consecutively with catheter drainage combined with polidocanol sclerotherapy by the same doctor at Beijing Tsinghua Changgung Hospital from Jan 2021 to May 2024 were retrospectively analyzed. The effectiveness and safety were statistically evaluated, and the relationship between drainage volume and cyst volume was analyzed.Results:Among the 38 patients with thyroid cysts who completed the treatment, the median follow-up was 9 months (range: 3-24 months). The effectiveness rate was 92% (35/38), of which 32 cases (84%) met the cure standard. The maximum diameter of the cysts before treatment was (4.8±1.0) cm, and the maximum diameter of the residual nodules after treatment was (1.5±1.1) cm, the difference was statistically significant ( t=17.389, P<0.01). The amount of drainage exudate is related to the volume of the cyst and the maximum diameter before treatment ( t=-3.149, P=0.003; t=-3.057, P<0.005). 19% of patients showed transient low fever after the injection of polidocanol, with no other complications. Conclusion:For large thyroid cysts, ultrasound-guided percutaneous catheterization for continuous negative pressure drainage combined with polidocanol sclerotherapy is a safe and effective method.

Gaucher disease is an autosomal recessive genetic disorder, with membranoproliferative glomerulonephritis (MPGN) being a rare complication. Here we present a case of type I Gaucher disease complicated with MPGN to improve the understanding of this disease. For patients presenting with abdominal distension, hepatosplenomegaly and myelofibrosis, Gaucher disease should be considered to avoid misdiagnosis and inappropriate treatment. The detection of β-glucosidase, genetic mutation analysis and histopathological examination can play crucial roles in the diagnosis of Gaucher disease. Treatment with glucocorticoids combination with immunosuppressants can improve patient's prognosis.

Objective:To evaluate the efficacy of corticosteroids in male children with Duchenne muscular dystrophy (DMD), and provide evidence for the rational clinical use of medication.Methods:This was a multicenter medical record series study which conducted from January 15 th to March 14 th, 2025. A total of 53 male children with DMD admitted to the Department of Rehabilitation of Children′s Hospital, Zhejiang University School of Medicine, Children′s Hospital of Chongqing Medical University and Affiliated Children′s Hospital of Soochow University from 2020 to 2024 were enrolled. Clinical data, corticosteroid usage, and the follow-up data were collected. The North star ambulatory assessment (NSAA) was used as the primary efficacy indicator. Generalized estimating equations (GEE) exchangeable working matrices were used for longitudinal analysis, and the least squares mean were used to compare the change trend of the efficacy evaluation index across different medication durations. Results:The age at the initiation of corticosteroid treatment was (6.3±1.9) years. The follow-up duration was 1.2 (0.9, 2.2) years. After treatment, the raw scores and linear scores of NSAA were both significantly higher than those before treatment ((22±7) vs. (19±5) points, (60±16) vs. (53±8) points; t=3.98, 3.69; both P<0.001). The 10 meter running time and time rising from floor were both shorter than those before treatment (6 (4, 8) vs. 7 (6, 9) s, 5 (3, 6) vs. 6 (5, 9) s; Z=2.62, 3.47; both P<0.01). GEE model analysis revealed all nonlinear correlation between motor function (NSAA linear score, 10-meter running velocity, and rising from floor velocity) and the duration of corticosteroid treatment (all P<0.05). Least squares mean comparison all showed that the medication effect first increased and then decreased with duration, reaching the peak at 1.1-2.0 years after treatment (all P<0.05). Conclusions:Corticosteroids can improve the motor function in male children with DMD, with the maximum treatment effect occurring 1 to 2 years after the initiation of treatment. It is necessary to comprehensively leverage time-varying efficacy of corticosteroids to optimize individualized treatment regimens for maximal motor function benefits in children with DMD.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective To construct a dynamic framework for bidirectional transitions of mild cognitive impairment(MCI),quantifying both rare reversion and high-risk progression trajectories in cognitive dynamics.Methods Patients diagnosed with MCI at baseline from 2005 to 2022 and completed at least two follow-up visits were selected from the Alzheimer's Disease Neuroimaging Initiative(ADNI),and a retrospective cohort was constructed.Demographic information,APOEε4 genotype,and neuropsychological scales data were collected.Longitudinal cognitive assessments were functionally reconstructed using multivariate functional principal component analysis(MFPCA),with functional principal components(FPCs)extracted based on cumulative variance contribution rate(PVE＞90％).Functional multi-state Markov models were developed to estimate inter-state transition intensities,year to year transition probabilities,and covariate effects.Results Among 1,019 MCI patients(4,657 follow-up visits),93(9.1％)reverted to normal cognition,while 359(35.2％)progressed to Alzheimer's disease(AD).Longitudinal trajectory analysis revealed significant heterogeneity:progressive MCI＞stable MCI＞reverted MCI in the first functional principal component(MFPC1)scores.The transition intensity for MCI reversion(0.020)was approximately one-fourth of the AD progression risk(0.086),but the post-reversion cognitive re-impairment intensity was 0.138.Reduced MFPC1(HR=0.993,95％Cl:0.991,0.995)and elevated MFPC2(HR=1.004,95％Cl:1.001,1.007)were closely associated with MCI reversion.Conclusion MCI exhibits marked heterogeneity in longitudinal cognitive trajectories.Although reversion is rare,reversed patients remain at high risk of cognitive re-impairment.

Objective To explore the neuroelectrophysiological mechanism of the decline of overall cognitive function and prospective memory,the syndrome manifestation of liver failing to govern conveyance and dispersion of the middle-aged and elderly people in the community with long-term emotional disturbance were evaluated.Methods Eysenck personality questionnaire(EPQ)and general condition questionnaire were used to screen the middle-aged and elderly people from 46 to 65 years old in the community who met the high and low neuroticism criteria,which were included in the long-term emotional disturbance group and the control group.According to the principle of matching sex,age(±2 years)and years of education(±2 years),60 subjects in each group were included.The scores of livers meridian syndrome,anxiety factor,depression factor and the total scores of three factors in the two groups were detected with the emotion rating scale for Ganzangxiang of traditional Chinese medicine.The overall cognitive function,the overall level of prospective memory and the dual-task paradigm of event-related memory were evaluated and event-related potential components were detected.Results Compared to the control group,the total scores of emotion rating scale for Ganzangxiang of traditional Chinese medicine and the scores of liver meridian syndrome factor,anxiety factor and depression factor all increased in the long-term emotional disturbance group significantly(P<0.05).The total scores of MoCA scale(after correction)and the level scores of visual space and executive function,attention and delayed recall decreased significantly(P<0.05),and the total scores of prospective memory questionnaire decreased significantly(P<0.05).The correct rates of ongoing tasks and prospective memory tasks in the event-based prospective memory dual task paradigm were decreased,and the reaction time was prolonged in the long-term emotional disorder group significantly(P<0.05).The amplitude of P200 of ongoing task and prospective memory task were increased in the long-term emotional disorder group(0.05
