Drug repurposing offers a promising alternative to traditional drug development and significantly re-duces costs and timelines by identifying new therapeutic uses for existing drugs.However,the current approaches often rely on limited data sources and simplistic hypotheses,which restrict their ability to capture the multi-faceted nature of biological systems.This study introduces adaptive multi-view learning(AMVL),a novel methodology that integrates chemical-induced transcriptional profiles(CTPs),knowledge graph(KG)embeddings,and large language model(LLM)representations,to enhance drug repurposing predictions.AMVL incorporates an innovative similarity matrix expansion strategy and leverages multi-view learning(MVL),matrix factorization,and ensemble optimization techniques to integrate heterogeneous multi-source data.Comprehensive evaluations on benchmark datasets(Fdata-set,Cdataset,and Ydataset)and the large-scale iDrug dataset demonstrate that AMVL outperforms state-of-the-art(SOTA)methods,achieving superior accuracy in predicting drug-disease associations across multiple metrics.Literature-based validation further confirmed the model's predictive capabilities,with seven out of the top ten predictions corroborated by post-2011 evidence.To promote transparency and reproducibility,all data and codes used in this study were open-sourced,providing resources for pro-cessing CTPs,KG,and LLM-based similarity calculations,along with the complete AMVL algorithm and benchmarking procedures.By unifying diverse data modalities,AMVL offers a robust and scalable so-lution for accelerating drug discovery,fostering advancements in translational medicine and integrating multi-omics data.We aim to inspire further innovations in multi-source data integration and support the development of more precise and efficient strategies for advancing drug discovery and translational medicine.

Objective:To investigate the regulatory effects of transcutaneous auricular vagus nerve stimulation (taVNS) on functional connectivity (FC) of thalamic subregions in patients with premenstrual syndrome (PMS).Methods:This study was a cross-sectional investigation. Clinical, laboratory, and imaging data were retrospectively collected from 56 PMS patients (PMS group) and 66 healthy controls (control group) recruited from various universities and hospitals in Nanning between November 2021 and June 2024. Resting-state functional MRI (fMRI) data and fMRI data during taVNS immediate stimulation (2 Hz, 25 Hz) were acquired from subjects during their late luteal phase. Using thalamic subregions (anterior thalamic nucleus, lateral nucleus, ventral nucleus, medial nucleus, central nucleus, posterior nucleus) as seeds, two-sample t-tests or paired t-tests were employed to analyze alterations in thalamic subregion FC in PMS patients and the regulatory effects of taVNS on these changes. Independent samples t-test were used to compare the differences in clinical and laboratory indicators between the PMS group and the control group. The relationship between taVNS regulation of thalamic subregion FC in PMS patients and thalamic internal functional connectivity were analyzed using mediation effect analysis. Results:Compared to the control group, patients in the PMS group showed increased scores on the Daily Record of Severity of Problems, Pittsburgh Sleep Quality Index, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Hamilton Anxiety Rating Scale 17, and Hamilton Depression Rating Scale 14 during the late luteal phase ( P<0.05). At baseline, PMS patients exhibited higher FC between the left thalamic lateral nucleus and the left insula, and lower FC between the left medial nucleus, posterior nucleus, and ventral nucleus of the thalamus and the right middle frontal gyrus (MFG) compared to the control group (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). During 2 Hz taVNS immediate stimulation in PMS group, FC between the left thalamic medial nucleus, posterior nucleus, ventral nucleus and the right MFG, as well as the FC between the left thalamic ventral nucleu and the left MFG increased compared to baseline levels; meanwhile, FC between the left thalamic posterior nucleus, ventral nucleus and the left insula decreased compared to baseline levels (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). During 25 Hz taVNS immediate stimulation, the FC between the left thalamic ventral nucleus and the right MFG decreased compared to the baseline level (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). Mediation effect analysis showed that the FC between the left thalamic posterior nucleus and the left lateral nucleus mediated part of the association between the FC of the left lateral thalamic nucleus-left insula and the FC of the left ventral thalamic nucleus-left putamen/insula; there were significant direct effects between the FC of the left lateral thalamic nucleus-the left posterior nucleus and FC of the left lateral thalamic nucleus-the left insula, as well as between the FC of the left ventral thalamic nucleus-the left MFG and FC of the left ventral thalamic nucleus-the right MFG. Conclusions:taVNS can modulate abnormal FC of the left thalamic subregions in PMS patients, restoring it toward normalization. The regulatory effects of 2 Hz stimulation are more pronounced than those of 25 Hz stimulation. This modulation primarily operates through two pathways: the left thalamic lateral nucleus-left insula-left thalamic ventral nucleus pathway and the left MFG-left thalamic ventral nucleus-right MFG.

Objective:To evaluate the changes of right atrial volume and function in patients with atrial septal defect(ASD)by four-dimensional ultrasound automatic quantitative technology,and to explore the predictive value and clinical significance for ASD with pulmonary arterial hypertension(PAH).Methods:Sixty-one patients with ASD and 32 healthy volunteers(control group)who attended Central China Fuwai Hospital of Zhengzhou University,Fuwai Central China Cardiovascular Hospital from March 2023 to April 2024 were prospectively collected,and classified ASD patients into ASD without PAH group(non-PAH group, n=30)and ASD with PAH group(PAH group, n=31)according to whether or not they had PAH,and obtained right atrial reserve,ductal,systolic longitudinal and circumferential strains(RASr,RAScd,RASct,RASr-c,RAScd-c,RASct-c),right atrial minimal,maximal,and presystolic volumes(RAVmin,RAVmax,and RAVpreA),and calculated right atrial total,passive,and active ejection fraction(RAEF,RAPEF,RAAEF). The ultrasound parameters and clinical data were compared between groups. Pearson's linear correlation was applied to analyse the correlation between the parameters(RASr,RAA,PASP,NT-proBNP)and mean pulmonary artery pressure(mPAP). ROC curves were plotted and the area under the curve(AUC)was calculated to analyse the value of the four-dimensional strain parameters of the right atrium in independently and jointly predicting the combination of ASD with PAH. Results:①Compared with the control group,RAVmin,RAVmax,and RAVpreA were elevated in the non-PAH and PAH groups,and the absolute values of RAPEF and RAScd were decreased,whereas the absolute values of RAEF,RAAEF,RASr,RASct,RASr-c,and RASct-c were elevated in the non-PAH group,and decreased in the PAH group(all P<0.05);compared with the non-PAH group,only RAVmin,RAVmax,and RAVpreA were elevated in the PAH group,and the rest of the above parameters were reduced,with statistically significant differences(all P<0.05). ②The right atrial four-dimensional strain parameter RASr had the highest predictive value for ASD combined with PAH,with an AUC of 0.876,a specificity of 83.3%,and a sensitivity of 77.4%,respectively. ③RASr was negatively correlated with mPAP( r=-0.591, P<0.001)and RAA,PASP and NT-proBNP were positively correlated with mPAP( r=0.539,0.697,0.616;all P<0.001). ④The predictive value of RASr combined with RAA,PASP,and NT-proBNP was superior for ASD combined with PAH(AUC=0.933). Conclusions:Four-dimensional ultrasound automatic quantitative technology can effectively evaluate the changes of right atrial volume and function in patients with ASD. ASD patients without PAH have increased right atrial reserve and pump function,and decreased right atrial pipeline function. The right atrial function of ASD patients with PAH is significantly reduced,and the impairment is more severe. Among the right atrial four-dimensional strain parameters,RASr has the highest efficacy in predicting ASD combined with PAH. Moreover,the combination of RASr with RAA,PASP,and NT-proBNP has the best predictive efficacy for ASD combined with PAH,which holds significant clinical value.

Guided by the theory of latent pathogens, it is believed that the basic pathogenesis of adult-onset Still's disease is the latent pathogens in the deep yin level. The onset of the disease is fundamentally characterized by the deficiency of both qi and yin as the root, with dampness, heat, phlegm, and blood stasis as the branch, which triggered by intruding pathogens activate the latent pathogens in yin level. The treatment focuses on nourishing yin and dispersing heat as the key therapeutic method. It is proposed that clearing and resolving dampness-heat, expelling pathogens outward, dispersing the latent pathogens, reinforcing healthy qi and consolidating the root, boosting qi and nourishing yin as treatment idea. In clinic, Qinghao Biejia Decoction (青蒿鳖甲汤) could be used as the basic formula, and modified with characteristic herb pairs such as Qinghao (Artemisia annua) - Digupi (Lycium chinense) to enrich yin and clear heat, and enforce the power of clearing deficient heat; Biejia (Lawsonia inermis) - Xuchangqing (Vincetoxicum mukdenense) to enrich yin and activate blood, unblock the collaterals and dissipate masses; Duhuo (Angelica biserrata) - Mudanpi (Paeonia × suffruticosa) to dispel wind and activate blood, resolve dampness and unblock the collaterals, so as to clear and warm simultaneously, and regulate qi and blood at the same time; and Chuanshanlong (Dioscorea nipponica) - Difuzi (Bassia scoparia) to dissolve stasis and dispel phlegm, explore and dispel latent pathogens.

Objective To analyze the relationship between the fat content of supraspinatus muscle measured by spectral CT fat-muscle material decomposition technology and the tendon tear severity(TTS)of supraspinatus,as well as shoulder joint function.Methods A total of 108 patients were prospectively selected to undergo routine MRI and spectral CT imaging of the shoulder joints.The patients were divided into normal,degenerative,partial tear,and full-thickness tear groups based on MRI findings.A fat-muscle material decomposition image was generated through spectral analysis to measure the fat content of supraspinatus muscle.The differences in fat content of supraspinatus muscle between the groups were compared,and correlation analyses were performed between the fat content of supraspinatus muscle and the clinical baseline characteristics,symptom duration,and Constant-Murley scores in patients with supraspinatus tendon tears.Results Comparison of supraspinatus muscle fat content among the four groups:the full-thickness tear group>the partial tear group>the degenerative group>the normal group(P<0.05).There was a strong positive cor-relation between the supraspinatus muscle fat content and the supraspinatus TTS(r=0.654,P<0.05).Among patients with partial and full-thickness tears of the supraspinatus tendon,there was a moderate positive correlation between supraspinatus muscle fat content and patient age(r=0.393,P<0.05),a weak positive correlation with gender(r=0.199,P<0.05),with higher fat content observed in females compared to males,no significant correlation with symptom duration(r=0.037,P>0.05),a moderate positive correla-tion with body mass index(BMI)(r=0.463,P<0.05),and a moderate negative correlation with Constant-Murley score(r=-0.316,P<0.05).Conclusion In patients with rotator cuff tears,the quantitative fat content of supraspinatus muscle based on spectral CT fat-muscle material decomposition technology is strongly positively correlated with rotator cuff injury degree,and is also correlated with patient age,gender,BMI,and the strength of the shoulder joint muscles and range of the motion.
