ObjectiveMigraine is a leading neurological disorder and the fourth most common cause of years lived with disability worldwide, affecting nearly 116 million individuals. Although pharmacological treatments are available, their efficacy is often limited by side effects and variable response rates. Repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) offers a safe, non-invasive alternative for migraine management. However, the neurophysiological mechanisms, particularly how rTMS modulates local cortical excitability and distributed pain-related circuits, remain poorly understood. Elucidating these mechanisms is essential for optimizing treatment protocols and improving clinical outcomes. MethodsThis study employed concurrent transcranial magnetic stimulation and electroencephalography (TMS-EEG) to investigate neuroplastic and neurocircuitry mechanisms of DLPFC-rTMS in migraine. Study 1 compared 30 migraineurs and 28 healthy controls to identify abnormalities in TMS-evoked potentials (TEPs) and significant current density (SCD) within sensory-discriminative regions including the primary somatosensory cortex (S1) and posterior insula (pINS), cognitive-affective regions including the anterior insula (aINS) and midcingulate cortex (MCC), and a descending modulatory region, the periaqueductal gray (PAG). Study 2 used a single-blind, crossover, sham-controlled design in 34 healthy participants. Each participant received both active (10 Hz, 80% RMT, 1 500 pulses) and sham DLPFC-rTMS in counterbalanced order. TMS-EEG and cold pain tolerance were assessed before and after each session. ResultsIn Study 1, migraineurs showed a significantly less negative N120 amplitude compared to healthy controls (P=0.027, Cohen’s d=0.60), indicating local intracortical disinhibition. No group differences were observed for N40, P60, or P180 components. At the source level, migraineurs exhibited significantly higher SCD in the S1, pINS, aINS, and MCC (allQ<0.05), but not in the ventroposterior thalamus (vpTHAL), mediodorsal thalamus (mdTHAL), or PAG. In Study 2, active rTMS significantly reduced SCD from pre- to post-stimulation in the S1, aINS, and MCC (all Q<0.05). Sham stimulation also reduced SCD in the S1 (Q<0.05) but not in the aINS or MCC. Although no significant group-level analgesic effect was observed between active and sham conditions (P=0.107), correlation analyses revealed that greater SCD reductions in the S1 and MCC were significantly associated with higher post-rTMS pain tolerance (R=-0.487 and -0.495, both Q<0.01) and larger improvements in pain tolerance(R=-0.487 and -0.451, both Q<0.05). No such correlations were found following sham stimulation, suggesting that the behavioural relevance of neural changes is specific to active rTMS. ConclusionThis study provides novel evidence that migraineurs exhibit both local neuroplastic abnormalities (reduced N120 amplitude) and hyperactivity in key pain-processing regions (S1, pINS, aINS, MCC). A single session of DLPFC-rTMS reduced hyperactivity in the aINS, MCC, and S1. Notably, greater reductions in the S1 and MCC were associated with improved pain tolerance. These findings identify distinct cortical circuitries, particularly within the cognitive-affective pain network, that may serve as potential biomarkers for optimizing rTMS treatment in migraine and other chronic pain conditions. Future studies should validate these results in patient populations experiencing spontaneous migraine attacks and explore multi-session or accelerated rTMS protocols.

Objective:To explore the relationship between international collaboration papers and academic impact in global health,using the member universities of the Chinese Consortium of Universities for Global Health(CCUGH)as a case study.Methods:The study focuses on journal articles in global health field published by 31 CCUGH member universities between 2014 and 2024.Descriptive statistical analysis of international and non-international collaboration publication volumes was conducted using Excel.Regression analysis and chi-square tests were performed using R to examine the relationship between international collaboration papers and academic impact,and the correlation between the breadth of collaboration and the academic impact of the papers.Results:From 2014 to 2023,the total number of publications,the number of non-international collaborationpublications,and the number of internationally collaborated publications all showed a consistent annual increase,with average annual growth rates of 56.7%,68.3%,and 41.4%,respectively.By the first half of 2024,the total number of publications had increased to 1.5 times that of the corresponding period in 2023.International collaboration positively influenced academic impact,with broader collaborative networks correlating with higher academic influence.Conclusion:The global health publication output of CCUGH member universities has steadily increased,but the volume of international collaboration papers and their proportion remain relatively low.Therefore,it is necessary for CCUGH member universities to strengthen international collaboration papers in global health.

Objective:To investigate effect of hospital-family chain rehabilitation management mode on self-man-agement and quality of life in elderly patients with coronary heart disease(CHD).Methods:This randomized con-trolled study enrolled 220 elderly CHD patients admitted in Hai'an Hospital of Traditional Chinese Medicine between December 2020 and August 2022.They were divided into control group(n=110,routine nursing)and intervention group(n=110,hospital-family chain rehabilitation management mode nursing).After 6-month intervention,scores of Coronary Self-Management Scale(CSMS),China Questionnaire of Quality of life in patients with Cardio-vascular diseases(CQQC)and Perceived Social Support Scale(PSSS)were compared between two groups as well as incidence of adverse cardiovascular events.Pearson method was employed to analyze the association among total scores of CSMS,CQQC and PSSS.Results:After 6-month nursing,compared with patients in control group,those in intervention group had significant higher CSMS total score[(116.03±5.41)points vs.(89.97±4.21)points],CQQC total score[(107.30±6.99)points vs.(80.86±6.38)points],PSSS total score[(69.05±7.42)points vs.(57.05±5.19)points]and each dimensional score(P＜0.001 all).Pearson correlation analysis indica-ted that total scores of CSMS,CQQC and PSSS were positively correlated with each other(r=0.437～0.562,P＜0.001 all).Incidence of adverse cardiovascular events in intervention group was significantly lower comparing to that of control group(2.73％vs.13.64％,P=0.003).Conclusion:Hospital-family chain rehabilitation manage-ment mode could improve the self-management ability and quality of life,increase the patient's social support,and reduce incidence of adverse cardiovascular events in elderly patients with coronary heart disease.

Objective:To develop a maternal assessment scale integrating both positive (affirmation, optimism, self-confidence) and negative psychological states (fear, anxiety, depression) throughout the entire pregnancy cycle and evaluate its reliability and validity.Methods:In December 2020, the scale items were preliminarily identified through a literature review, forming a 55-item questionnaire for pilot survey and expert interviews. A pilot survey was conducted among registered pregnant women at the Obstetrics and Gynecology Hospital of Fudan University from April to May 2021. The feasibility and reliability of the questionnaire was validated through reliability and validity analysis, and revisions were made based on the feedback. The finalized version comprised 43 items, categorized into four key event dimensions (pregnancy, childbirth, transition to motherhood, and complications) and six psychological state dimensions (affirmation, fear, anxiety, depression, optimism, and self-confidence). Among these psychological states, affirmation, self-confidence, and optimism represent positive states, while fear, anxiety, and depression reflect negative states. A formal survey was conducted from December 2021 to November 2022. The normality, multicollinearity, reliability, construct validity, convergent validity, and discriminant validity of each item were analyzed.Results:(1) General information: A total of 625 participants were involved in the pilot survey. For the formal survey, 8 045 questionnaires were distributed, with 6 273 valid responses (78.0%). Among the valid questionnaires, 5 694 (90.8%) reported positive psychological states and 579 (9.2%) negative states. All of the psychological state dimensions were correlated (all P<0.01), with no multicollinearity detected [variance inflation factor (VIF)<10]. The four key event dimensions were also correlated (all P<0.01), with no multicollinearity (VIF<10). (2) Reliability: The overall Cronbach's α coefficient of the questionnaire was 0.830, and removing any single item resulted in the value remaining>0.6. Cronbach's α coefficient values for affirmation, fear, anxiety, depression, optimism, and self-confidence were 0.772, 0.724, 0.648, 0.551, 0.257, and 0.740, respectively. The values for the key event dimensions were as follows: 0.722 for pregnancy, 0.554 for childbirth, 0.621 for transition to motherhood, and 0.568 for complications. (3) Model fit: For the psychological states, the Chi-square to degrees of freedom ratio ( χ2/df) was 19.979 (>3), and the root mean square error of approximation (RMSEA) was 0.055 (<0.08). The model of key event dimensions had a χ2/df of 48.557, RMSEA of 0.087, comparative fit index of 0.400 (<0.9), and incremental fit index of 0.400 (<0.9). (4) Convergent and discriminant validity: The average variance extraction (AVE) values for affirmation, fear, anxiety, depression, optimism, and self-confidence were 0.407, 0.099, 0.188, 0.223, 0.419, and 0.362, with composite reliability (CR) values of 0.822, 0.730, 0.655, 0.584, 0.627, and 0.786, respectively. In the model of key event dimensions, the AVE values for pregnancy, childbirth, transition to motherhood, and complications were 0.167, 0.287, 0.328, and 0.166, with CR values of 0.555, 0.832, 0.746, and 0.633, respectively. Significant correlations were observed between all psychological dimensions except optimism-depression and self-confidence-anxiety pairs (all P<0.05). All four key event dimensions were significantly correlated (all P<0.05). Conclusions:This study preliminarily develops a maternal psychological status assessment scale with satisfactory reliability and validity. This scale can be used to evaluate the comprehensive psychological states of pregnant women during critical pregnancy-related events.

Objective:To retrospectively analyze the detection and diagnosis process of two cases with double rare thalassemia genotypes,explore the causes of missed diagnosis and misdiagnosis of rare thalassemia,and improve the diagnosis level of rare thalassemia.Methods:Base on the family history,hematological phenotype and hemoglobin electrophoretic analysis results,the common genotypes of α and β-thalassemia were detected by PCR+diversion hybridization.DNA sequencing technology was used for rare α and β protein genes sequencing.Results:Both subjects were combined with double rare thalassemia genotypes,and both rare thalassemia gene combinations were reported for the first time.One of them was αβ complex thalassemia with αα*53_55 del TCC/αα heterozygous merger βIVS Ⅱ2(-T)/βN heterozygous,the other was ααIVS-Ⅱ-55(T→G)in α1/αα4,2-Q double azygous heterozygous α-thalassemia,among whichαα*53_55 del TCC/αα genotype was also reported for the first time.Conclusion:The reported rare gene type αα*53_55 del TCC/αα and two cases of rare gene combinations enriches the spectrum of gene mutations in the Chinese population,and provides richer molecular information for thalassemia diagnosis and eugenics counseling.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective To investigate the cumulative incidence of recurrence(CIR)in children with acute lymphoblastic leukemia(ALL)after treatment with the Chinese Children's Cancer Group ALL-2015(CCCG-ALL-2015)protocol and the risk factors for recurrence.Methods A retrospective analysis was conducted on the clinical data of 852 children who were treated with the CCCG-ALL-2015 protocol from January 2015 to December 2019.CIR was calculated,and the risk factors for the recurrence of B-lineage acute lymphoblastic leukemia(B-ALL)were analyzed.Results Among the 852 children with ALL,146(17.1%)experienced recurrence,with an 8-year CIR of 19.8%±1.6%.There was no significant difference in 8-year CIR between the B-ALL group and the acute T lymphocyte leukemia group(P>0.05).For the 146 children with recurrence,recurrence was mainly observed in the very early stage(n=62,42.5%)and the early stage(n=46,31.5%),and there were 42 children with bone marrow recurrence alone(28.8%)in the very early stage and 27 children with bone marrow recurrence alone(18.5%)in the early stage.The Cox proportional-hazards regression model analysis showed that positive MLLr fusion gene(HR=4.177,95%CI:2.086-8.364,P<0.001)and minimal residual disease≥0.01%on day 46(HR=2.013,95%CI:1.163-3.483,P=0.012)were independent risk factors for recurrence in children with B-ALL after treatment with the CCCG-ALL-2015 protocol.Conclusions There is still a relatively high recurrence rate in children with ALL after treatment with the CCCG-ALL-2015 protocol,mainly bone marrow recurrence alone in the very early stage and the early stage,and minimal residual disease≥0.01%on day 46 and positive MLLr fusion gene are closely associated with the recurrence of B-ALL.
