In recent years， repetitive transcranial magnetic stimulation （rTMS） has garnered significant attention as a therapeutic approach for sleep disorders in the elderly. However， the prevailing rTMS protocols are predominantly developed based on normative neurophysiological data derived from young adults and fail to incorporate individualized parameters tailored to the brain characteristics of the elderly. To address this gap， the consensus development group synthesized the latest evidence from 2010 to 2025 and established a standardized rTMS protocol specifically for elderly patients with sleep disorders. Adhering to the Appraisal of Guidelines for Research and Evaluation II （AGREE II） framework， systematically screened randomized controlled trials （RCTs） and systematic reviews regarding rTMS in the treatment of sleep disorders across various conditions. Meanwhile， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system was employed to rigorously grade the quality of evidence and the strength of recommendations. This consensus guideline delineates precise rTMS protocols for the management of sleep disorders in the elderly， highlights the adjustment of stimulation intensity according to scalp-cortex distance recommends either MRI‑guided neuronavigation or the Beam F3/F4 heuristic approach for accurate target localization， thereby providing precise rTMS intervention protocol for sleep disorders in the elderly， aiming to enhance clinical efficacy while ensuring treatment safety. ［Funded by National Key Research and Development Program （number， 2023YFC3603200）； General Program of Shenzhen Science and Technology Innovation Commission （number， JCYJ20240813112859008， JCYJ20240813112900002）； Youth Program of Shenzhen Kangning Hospital （number， KN2023A004）； www.guidelines-registry.cn number， PREPARE-2026CN530］

Objective To investigate the comparative neuroprotective effects of human umbilical cord mesenchymal stem cells(hUC-MSCs-Exos)administered via different routes on hypoxic ischemic brain damage(HIBD)in neonatal mice.Methods Healthy one-week-old SPF-grade BALB/c mice were randomly divided into 4 groups:sham operation group(n=6),model group(n=6),exosome group 1(n=8),exosome group 2(n=8).HIBD was induced using the Rice-Vannucci method.Exosome group 1 and Exosome group 2 were intraperitoneal injection/intranasal drip of phosphate buffer(PBS)100 μl containing 10 μl exosomes within 24 h after successful modeling,respectively.Sham operation and model groups were intraperitoneal injection of PBS 100 μl.On the 7th day after the intervention,neuromotor function was assessed using the horizontal grid test and pole climbing test.On the 2nd day after the evaluation,all mice were killed and their brains were removed by decapitation.HE staining was used to observe the pathological injury of brain tissue,toluidine blue staining was used to observe the survival of neurons in cerebral cortex,and TUNEL staining was used to observe the apoptosis of cerebral cortex cells.Results Compared with sham operation group,model group,exosome group 1 and exosome group 2 exhibited increased hind limb drops in horizontal grid test and climbing scores(P<0.05).No significant difference was found in model group,exosome group 1 and exosome group 2 in these measures(P<0.05).Significant pathology was observed in model group,exosome group 1 and exosome group 2 compared to sham operation group(P<0.05),with significantly reduced damage in exosome group 1 and exosome group 2 compared to model group(P<0.05).Compared with sham operation group,Nissl body count was lower in model group and exosome group 1 and exosome group 2,with a higher count in exosome group 2 compared to exosome group 1(P<0.05).Compared with sham operation group,apoptotic cells were higher in model group and exosome group 1 and exosome group 2,with a significant reduction in exosome group 1 and exosome group 2 compared to model group,and the lowest in exosome group 2(P<0.05).Conclusions hUC-MSCs-Exos can improve the neuronal motor function,promote neuron repair and inhibit apoptosis in HIBD mice.Intranasal administration of hUC-MSCs-Exos is more effective than intraperitoneal administration for reducing neuronal apoptosis in HIBP neonatal mice,offering a convenient and rapid method suitable for clinical application.

Objective:To investigate the effects of curcumin,berberine,and puerarin combination therapy on lipid levels in hyperlipidemic mice.Methods:A total of 40 male C57BL/6J mice were randomly divided into eight groups:normal control group(A),high-fat control group(B),curcumin group(C),berberine group(D),puerarin group(E),low-dose combination group of curcumin,berberine,and puerarin(F),high-dose combination group of curcumin,berberine,and puerarin(G),and positive control group(H),with 5 mice in each group.The normal control group was fed a standard diet,while the other groups were given a high-fat diet.After establishing the hyperlipidemic model,the mice were administered with physiological saline,curcumin(200 mg/kg),berberine(200 mg/kg),puerarin(300 mg/kg),low-dose combination of curcumin(50 mg/kg),berberine(50 mg/kg),and puerarin(100 mg/kg),high-dose combination of curcumin(200 mg/kg),berberine(200 mg/kg),and puerarin(300 mg/kg),or simvastatin(6 mg/kg)via gavage for three weeks.After treatment,serum was collected from the mice for biochemical analysis of lipid levels and liver function.Liver tissues were subjected to HE staining,Western blot analysis and real-time quantitative PCR.Results:Curcumin,berberine,and puerarin,whether administered individually or in combination,can reduce the body weight of hyperlipidemic mice(P＜0.01).Treatment with curcumin,berberine,and puerarin individually significantly reduced lipid levels in hyperlipidemic mice(P＜0.05)and alleviated liver damage caused by hyperlipidemia(P＜0.05).Furthermore,the high-dose combination of curcumin,berberine,and puerarin exhibited a more pronounced effect on improving lipid levels(P＜0.01)and provided greater protective effects on the liver compared to the positive control group(P＜0.05).Additionally,curcumin,berberine,and puerarin administered individually can each promote the expression of the LDLR gene in high-fat diet mice(increased by 90％,85％,and 98％,respectively)and reduce the expression of the ACC gene(decreased by 42％,45％,and 43％,respectively).The combination of all three compounds enhances the expression of the LDLR gene in high-fat diet mice(increased by 90％with low-dose combination and 169％with high-dose combination)and reduces the expression of the ACC gene(decreased by 38％with low-dose combination and 42％with high-dose combination).Conclusion:The combination of curcumin,berberine,and puerarin significantly improves lipid levels in hyperlipidemic mice and mitigates liver damage associated with hyperlipidemia.

Objective To investigate the impact of mild hippocampal atrophy on life quality of patients with Parkinson's disease(PD)and its correlation with cognitive function.Methods A total of 34 PD patients were recruited from Nanjing Brain Hospital,assessed using the Unified Parkinson's Disease Rating Scale(UPDRS),the Parkinson's Disease Questionnaire(PDQ-39)and the Montreal Cognitive Assessment(MoCA),and underwent MRI scans to measure hippocampal volume.Results Compared with the PD without hippocampal atrophy(PD-nHA)group,the PD with hippocampal atrophy(PD-HA)group showed significantly higher age,PDQ-39 total score,and subscores in physical activity,daily living,cognition,and communication dimensions,along with significantly lower MoCA scores,total hippocampal volume,and bilateral posterior hippocampal volume(all P＜0.05).MoCA subdomain analysis revealed that the PD-HA group exhibited varying degrees of decline across visuospatial/executive function,naming,attention,language,abstraction,delayed recall,and orientation domains,although these differences did not reach statistical significance(all P＞0.05).Total hippocampal volume was negatively correlated with PDQ-39 scores in physical activity,cognition,communication,and total score(r=-0.453,P=0.007;r=-0.364,P=0.034;r=-0.355,P=0.039;r=-0.369,P=0.032),and positively correlated with MoCA total score and three cognitive domains:naming,language,and orientation(r=0.408,P=0.017;r=0.348,P=0.044;r=0.406,P=0.017;r=0.355,P=0.039).The PDQ-39 total score was negatively correlated with the MoCA total score(r=-0.468,P=0.005).Compared with baseline,the PD-HA group showed significantly increased PDQ-39 scores(t=2.378,P=0.039)and significantly decreased right anterior hippocampal gray matter volume(t=-2.751,P=0.022)at the final follow-up,while differences in total hippocampal volume and other hippocampal subregions were not statistically significant(all P＞0.05).MoCA scores showed a declining trend but did not reach statistical significance(t=-0.958,P=0.361).In the PD-nHA group,no statistically significant differences were observed in PDQ-39 scores,MoCA scores,or hippocampal volumes between baseline and final follow-up(all P＞0.05).Conclusions Hippocampal atrophy is closely related to cognitive decline and reduced quality of life in PD patients.Particularly,posterior hippocampal atrophy is more closely related to cognitive dysfunction,and cognitive function serves as a mediator between hippocampal atrophy and quality of life.Early interventions targeting cognitive impairment may help improve the quality of life for PD patients.

Objective To investigate the causal relationship between obstructive sleep apnea(OSA)and hypertension using bidirectional Mendelian randomization(MR).Methods Genetic data for OSA were obtained from the Genome-wide association study(GWAS)of FinnGen Biobank,including 16 761 cases and 201 194 controls,from which 5 single-nucleotide polymorphisms(SNPs)were screened as instrumental variables(IVs)for OSA.Genetic data for hypertension were obtained from GWAS of UK Biobank,including 124 227 cases and 337 653 controls from which 214 SNPs were selected as IVs for hypertension.Multiple MR methods,mainly Inverse variance weighted(IVW),were used for analysis.Sensitivity analysis of MR results was performed using MR-Egger regression et al,and IVs were evaluated using F values.Results OSA was associated with an increased risk of hypertension(OR=1.053,95%CI 1.019-1.089,P<0.01),and hypertension was significantly associated with the risk of developing OSA(OR=1.812,95%CI 1.354-2.425,P<0.001).Heterogeneity was observed in both two-way outcomes(OSA→ hypertension,P<0.001;hypertension→ OSA,P<0.001),but no evidence of horizontal pleiotropy was detected(OSA→ hypertension,P=0.666;hypertension→ OSA,P=0.556).The IVs selected in this study were strong instrumental variables for both OSA and hypertension(OSA-IVs F=14.695;hypertension-IVs F=39.624).Conclusions Our findings indicate a bidirectional causal relationship between OSA and hypertension,with a particularly significant effect of hypertension on the development of OSA.

Purpose To investigate the clinical,imaging,pathological features,differential diagnosis and prognosis of em-bryonic dysplastic neuroepithelial tumor(DNT).Methods The clinical data of 33 DNT patients were collected.Immunohis-tochemical results of Olig2,NeuN,Syn,GFAP,IDH1,CD34,BRAF V600E,H3K27M and Ki67 were examined by EnVision method.Histopathological morphology and immunohistochemical features were retrospectively analyzed and relevant literature was reviewed synchronously.Results A total of 28 cases were fol-lowed up,including 10 females and 18 males.The age of onset was 4～57 years,with average 24.97 years.Refractory epilepsy was a common symptom.The lesions were mainly located in the supratentorial cortex,and most of them were well-defined,lobu-lated,cystic or cystic and solid.Microscopically,DNT was mainly composed of oligodendrocytes,neurons floating in the mucous matrix,and proliferative astrocytes.Calcification was rare,and no necrosis or microvascular hyperplasia was ob-served.Immunohistochemistry showed that neurons expressed NeuN and Syn,oligodendrocytes expressed Olig2,and prolifera-tive astrocytes expressed GFAP;p53 was mostly wild-type,and the proliferation index of Ki67 was low(mostly less than 4％).Conclusion DNT is a benign tumor with mixed glial and neu-ronal structures.Precise pathological diagnosis needs to be care-fully considered with imaging characteristics,microscopic mor-phology,immunohistochemistry and molecular test results if nec-essary.Prognosis after complete surgical resection is good.
