Objective To investigate the effect of local vibration therapy(LVT)on fine motor function of upper extremity and surface electromyography characteristics in children with spastic hemiplegic cerebral palsy(SHCP).Methods Sixty children with SHCP were divided into the observation group and the control group using random number table method,with 30 cases in each group.The control group was given conventional rehabilitation treatment(physical therapy,occupational therapy,sensory integration training,physiotherapy and rehabilitation therapy of traditional Chinese medicine),while the observation group received LVT for the affected upper extremity in addition to conventional rehabilitation treatment.Both groups were treated for 12 weeks.Fine motor function of upper extremity on the hemiplegic side[Peabody Developmental Motor Scale-Fine Motor(PDMS-FM),Fine Motor Function Measure(FMFM)]and root mean square(RMS)value of the biceps surface electromyography were compared between the two groups as well as before and after treatment.Results Compared with those before treatment,both groups showed increases in PDMS-FM scores for grasping energy range,visual-motor integration energy range,fine motor development quotient,FMFM scores for upper extremity joint mobility ability,grasping ability,operation ability,hand-eye coordination ability and total scores,but a decrease in RMS value of biceps brachii after treatment(P＜0.05).After treatment,PDMS-FM scores for grasping energy range and visual-motor integration energy range,FMFM scores for upper extremity joint mobility ability and grasping ability and total score were higher in the observation group than those in the control group.The RMS value of biceps brachii was lower in the observation group than that of the control group(P＜0.05).Conclusion LVT can enhance the effect of conventional rehabilitation on fine motor function of upper extremity and electromyography characteristics in children with SHCP.

Objective To explore the effect of transcranial direct current stimulation(tDCS)in rehabilitation of swallowing function in stroke patients.Methods A total of 86 stroke patients diagnosed and treated in Affiliated Rehabilitation Hospital of Zhejiang Chinese Medical University from December 2022 to December 2023 were selected as study objects,and they were divided into observation group and control group according to random number table method,with 43 cases in each group.The control group received routine rehabilitation programs,while the observation group received tDCS therapy on the basis of control group.The swallowing function,actual swallowing process and quality of life of two groups were compared before and after intervention.Results After the intervention,standardized swallowing assessment scores of observation group were significantly lower than those of control group(P＜0.05).The scores of oral and pharyngeal phases of observation group were higher than those of control group(P＜0.05),and there was no significant difference in esophageal phase score between two groups(P＞0.05).The quality of life score of observation group was significantly higher than that of control group(P＜0.05).Conclusion tDCS can improve the swallowing function of stroke patients and improve the quality of life,which is worthy of clinical application.

Objective To evaluate the protective effects of the traditional Chinese medicine formula Shenxiankang on renal injury and fibrosis,and to explore its potential mechanisms of action.Methods Chronic kidney disease(CKD)model was established in mice using unilateral ureteral obstruction(UUO).The mice were randomly divided into four groups:sham,UUO,and Shenxiankang(SXK)Low/High dose groups(1500,4500 mg/(kg·d)),each comprising eight mice.The each SXK groups received daily oral administration of Shenxiankang,and the remaining mice were gavaged equivalent volumes of saline for 7 d.After the experiment,renal tissues were collected for assessment of renal injury and fibrosis using HE and Masson staining.The expression levels of fibrosis markers and proteins involved in the epithelial membrane protein 3(Emp3)and Tgf-β/Smad3 signaling pathway were determined by Real-time PCR,immunohistochemistry,and Western Blot.In cell-based experiments,the effects of Shenxiankang on the Emp3/Tgf-β/Smad3 pathway and its interaction with TGF-beta receptor R2(Tgfβ2)were further analyzed using an Emp3 knockdown and Co-IP assays.Results Shenxiankang significantly reduced immune cell infiltration and tubular atrophy in the UUO model group and decreased the expression of kidney injury markers kidney injury molecule 1(Kim1)and Lipocalin 2(Lcn2),confirming its efficacy in alleviating renal injury.Masson staining and analysis of fibrosis markers Fibronectin(Fn)and α-smooth muscle actin(α-SMA)indicated that Shenxiankang effectively suppressed fibrosis induced by UUO.Mechanistic studies revealed that Shenxiankang exerted its effects by selectively downregulating the abnormal activation of the Emp3/Tgf-β/Smad3 signaling pathway,a finding further supported by cellular experiments showing that Shenxiankang modulates Tgf-β/Smad3 signaling through Emp3 regulation.Moreover,the Co-IP experiment result indicate that Shenxiankang exerts its effects by regulating the interaction between Emp3 and Tgfβ2.Conclusions Shenxiankang exhibits significant protective effects in a mouse model of chronic kidney disease,effectively reducing renal injury and fibrosis.These effects are likely mediated through the downregulation of the Emp3/Tgf-β/Smad3 signaling pathway,suggesting Shenxiankang's potential therapeutic value in renal protection.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.
