Objective: To explore the association of vegetables and fruits intake with depressive symptoms among multi ethnic first year junior high school students in Yunnan Province, so as to provide data support for preventing and reducing depressive symptoms among first year junior high school students. Methods: From October to December 2022, a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas in Yunnan Province (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County), to investigate with a questionnaire. The Dietary Frequency Questionnaire was used to collect dietary behavior datas, and the Chinese version of Depression Anxiety Stress Scale-21 (DASS-21) was used to assess depressive symptoms. The generalized linear model was used to analyze the association of vegetable and fruit intake with depressive symptoms in students, and stratified analysis was performed according to ethnicity. Results: The detection rate of depressive symptoms among first year junior high school students in Yunnan Province was 29.5%. The detection rates of depressive symptoms in Han and minority first year junior high school students were 26.9% and 31.6%. After controlling for demographic variables such as gender, age, family residence and other confounding factors, the generalized linear model analysis results showed that the intake of leafy vegetables ( β= -0.07 , 95%CI =-0.12 to -0.01), flat fruits ( β=-0.06, 95%CI =-0.12 to -0.00) and hot natured fruits ( β=0.11, 95%CI = 0.04- 0.17) were associated with depressive symptoms in Han first year junior high school students (all P <0.05). The intake of melon and fruit vegetables ( β=-0.06, 95%CI =-0.11 to -0.01) and hot natured fruits ( β=0.06, 95%CI =0.01-0.12) were associated with depressive symptoms in ethnic minority first year junior high school students (both P <0.05). Conclusions The intake of vegetables and fruits among multi ethnic first year junior high school students in Yunnan Province is related to the risk of depressive symptoms. It is suggested to strengthen the consumption guidance and education of vegetables and fruits to prevent depressive symptoms among first year junior high school students.

Objective To explore the application of plasma 7 microRNA (miR7) testing in the differential diagnosis of very early-stage hepatocellular carcinoma (HCC). Methods This study is a multicenter real-world study. Patients with single hepatic lesion (maximum diameter≤2 cm) who underwent plasma miR7 testing at Zhongshan Hospital, Fudan University, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Anhui Provincial Hospital, and Peking University People’s Hospital between January 2019 and December 2024 were retrospectively enrolled. Patients were divided into very early-stage HCC group and non-HCC group, and the clinical pathological characteristics of the two groups were compared. The value of plasma miR7 levels, alpha-fetoprotein (AFP), and des-gamma-carboxy prothrombin (DCP) in the differential diagnosis of very early-stage HCC was evaluated using receiver operating characteristic (ROC) curves and area under the curve (AUC). In patients with both negative AFP and DCP (AFP＜20 ng/mL, DCP＜40 mAU/mL), the diagnostic value of plasma miR7 for very early-stage HCC was analyzed. Results A total of 64 528 patients from 4 hospitals underwent miR7 testing, and 1 682 were finally included, of which 1 073 were diagnosed with very early-stage HCC and 609 were diagnosed with non-HCC. The positive rate of miR7 in HCC patients was significantly higher than that in non-HCC patients (67.9% vs 24.3%, P＜0.001). ROC curves showed that the AUCs for miR7, AFP, and DCP in distinguishing HCC patients from the non-HCC individuals were 0.718, 0.682, and 0.642, respectively. The sensitivities were 67.85%, 43.71%, and 44.45%, and the specificities were 75.70%, 92.78%, and 83.91%, respectively. The pairwise comparison of AUCs showed that the diagnostic efficacy of plasma miR7 detection was significantly better than that of AFP or DCP (P＜0.05). Although its specificity was slightly lower than AFP and DCP, the sensitivity was significantly higher. Among patients negative for both AFP and DCP, miR7 maintained an AUC of 0.728 for diagnosing very early-stage HCC, with 67.82% sensitivity and 77.73% specificity. Conclusions Plasma miR7 testing is a potential molecular marker with high sensitivity and specificity for the differential diagnosis of small hepatic nodules. In patients with very early-stage HCC lacking effective molecular markers (negative for both AFP and DCP), miR7 can serve as a novel and effective molecular marker to assist diagnosis.

Drug repurposing offers a promising alternative to traditional drug development and significantly reduces 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 (Fdataset, 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 processing 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 solution 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 Intracranial hemorrhage(ICH),the second most common subtype of stroke,exacerbates the disruption of the blood-brain barrier(BBB),leading to vasogenic edema,plasma protein extravasation,and infiltration of neurotoxic substances.The clearance capacity of the brain plays a crucial role in maintaining BBB homeostasis and facilitating patient recovery after hemorrhage.This study aimed to investigate the effect of circadian rhythms on BBB function,neuronal damage,and clearance capabilities. Methods The transwell model and hemoglobin were co-cultured to simulate the BBB environment after ICH.After intervention with different light groups,neuronal apoptosis was determined,glial phagocytosis was analyzed,the expression of endogenous clearing-related proteins aquaporin 4(AQP4)and low-density lipoprotein receptor-related protein 1(LRP1)was detected by western blotting and immunofluorescence dual standard method,and the expression of the tight junction protein occludin and melatonin receptor 1A(MTNR1A)was quantitatively analyzed. Results Circadian rhythms play a key role in maintaining the integrity of the BBB,reducing oxidative stress-induced neuronal damage,and improving microglial phagocytosis.Meanwhile,the expression of occludin and MTNR1A in neurovascular unit(NVU)co-cultured with hemoglobin improved the expression of AQP4 and LRP1,the key proteins in the NVU's endogenous brain clearance system. Conclusion Circadian rhythm(alternating black and white light)protects the NVU BBB function after ICH,promotes the expression of proteins related to the clearance of the hematoma,provides new evidence for the clinical treatment of patients recovering from ICH,and improves the circadian rhythm to promote brain metabolism and hematoma clearance.

Objective To construct a risk prediction score model for serious adverse event (SAE) after cardiac catheterization in patients with adult congenital heart disease (ACHD) and pulmonary hypertension (PH) and verify its predictive effect. Methods The patients with PH who underwent cardiac catheterization in Wuhan Asian Heart Hospital Affiliated to Wuhan University of Science and Technology from January 2018 to January 2022 were retrospectively collected. The patients were randomly divided into a model group and a validation group according to the order of admission. The model group was divided into a SAE group and a non-SAE group according to whether SAE occurred after the catheterization. The data of the two groups were compared, and the risk prediction score model was established according to the results of multivariate logistic regression analysis. The discrimination and calibration of the model were evaluated using the area under the receiver operating characteristic (ROC) curve and the Hosmer-Lemeshow test, respectively. Results A total of 758 patients were enrolled, including 240 (31.7%) males and 518 (68.3%) females, with a mean age of 43.1 (18.0-81.0) years. There were 530 patients in the model group (47 patients in the SAE group and 483 patients in the non-SAE group) and 228 patients in the validation group. Univariate analysis showed statistical differences in age, smoking history, valvular disease history, heart failure history, N-terminal pro-B-type natriuretic peptide, and other factors between the SAE and non-SAE groups (P<0.05). Multivariate analysis showed that age≥50 years, history of heart failure, moderate to severe congenital heart disease, moderate to severe PH, cardiac catheterization and treatment, surgical general anesthesia, and N-terminal pro-B-type natriuretic peptide≥126.65 pg/mL were risk factors for SAE after cardiac catheterization for ACHD-PH patients (P<0.05). The risk prediction score model had a total score of 0-139 points and patients who had a score>50 points were high-risk patients. Model validation results showed an area under the ROC curve of 0.937 (95%CI 0.897-0.976). Hosmer-Lemeshow goodness-of-fit test: χ2=3.847, P=0.797. Conclusion Age≥50 years, history of heart failure, moderate to severe congenital heart disease, moderate to severe PH, cardiac catheterization and treatment, general anesthesia for surgery, and N-terminal pro-B-type natriuretic peptide≥126.65 pg/mL were risk factors for SAE after cardiac catheterization for ACHD-PH patients. The risk prediction model based on these factors has a high predictive value and can be applied to the risk assessment of SAE after interventional therapy in ACHD-PH patients to help clinicians perform early intervention.

Tendons play a crucial role in the motor system. However, tendon injuries can result in pain and function decline, a condition known as tendinopathy. Pain is often the earliest symptom, significantly impacting the lives and work of patients. There are many methods for addressing tendinopathy-associated pain, but the treatment is lengthy and the outcomes are not satisfactory. The main cause is that the mechanism of tendinopathy-associated pain is not completely clear yet. Therefore, it is of great value to identify the mechanism of tendinopathy-associated pain in order to discover new therapeutic strategies. To this end, the authors reviewed the research progress in the mechanisms of tendinopathy-associated pain, including changes in tissue structure, pain mediators, central regulation, etc, to provide a reference for researches on the mechanisms and clinical treatment of tendinopathy-associated pain.

Objective: To explore the association between processed food consumption and anxiety symptoms among college students in Yunnan Province, so as to provide a reference for the prevention and treatment of anxiety symptoms in this population. Methods: A cluster random sample of 2 515 first year students from two universities in Yunnan Province was selected to carry out a longitudinal investigation which included a baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The food frequency questionnaire was administered to assess processed food consumption, and the Depression Anxiety Stress Scale-21 (DASS-21, Chinese version) was used to evaluate anxiety symptoms. A generalized estimation equation model was used to analyze the relationship between processed food consumption and anxiety symptoms. Results: The detection rates of T1-T4 anxiety symptoms among college students in Yunnan Province were 29.70%, 36.70%, 37.69% and 38.73 %, respectively, and the corresponding anxiety symptom scores were 4(0,8), 4(0,10), 4(0,12), 2(0,14). After controlling for demographic variables and confounding factors in the generalized estimation equation model, a statistically significant association was found between consumption of carbonated beverages ( β=0.06, 95%CI =0.03-0.08), and other processed snacks ( β= 0.04 , 95%CI =0.01-0.07) ( P <0.05). The stratified analysis by gender showed that the consumption of carbonated beverages ( β=0.08, 95%CI =0.05-0.12) and fast food ( β=0.03, 95%CI =0.00-0.06) was significantly associated with anxiety symptoms in female college students ( P <0.05). There was no significant association between processed food consumption and anxiety symptoms in male college students ( P >0.05). Conclusions Processed food consumption by college students in Yunnan Province may increase the risk of anxiety symptoms, particularly among female students. There is a need to strengthen guidance in respect to processed food consumption, so as to prevent and treat anxiety symptoms.

Objective To explore the effect and mechanism of sodium hydrosulfide(NaHS)on cerebral cortical injury in rats with cerebral ischemia-reperfusion.Methods A total of 80 male SD rats were divided into a sham operation group,an NaHS group,an ischemia-reperfusion group,and an ischemia-reperfusion+NaHS group using a random number table method,with 20 rats in each group.The rats in the ischemia-reperfusion group and ischemia-reperfusion+NaHS group were used to prepare ischemia-reperfusion models.The rats in the ischemia-reperfusion+NaHS group were given 50 μmol·kg-1 NaHS intraperitoneally after cerebral ischemia,while the rats in the ischemia-reperfusion group were given an equal volume of physiological saline intraperitoneally after cerebral ischemia.The rats in the sham operation group and NaHS group only had vessels isolated but not occluded with threads.The rats in the NaHS group were given 50 μmol·kg-1 NaHS intraperitoneally after vascular detachment,while the rats in the sham operation group were given an equal volume of physiological saline intraperitoneally after vascular detachment.Twenty-four hours after modeling,the neurological deficits of rats in the four groups were evaluated by using the modified neurological severity score(mNSS),the cerebral infarction of rats in the four groups was observed aftertriphenyltetrazolium chloride staining,the levels of pro-inflammatory cytokines interleukin-1β(IL-1β)and interleukin-18(IL-18)in theischemiccerebralcortical tissues of rats in the four groups were detected by using enzyme-linked immunosorbent assay,the expression of nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)in the ischemic cerebral cortical tissues of rats in the four groups was detected by using Western blot,and the activity of microglia in the ischemic cerebral cortical tissues of rats in the four groups was detected by using immunofluorescence.Results The brain tissues of rats in the sham operation group and the NaHS group showed uniform orange red color,while the rats in the ischemia-reperfusion group and the ischemia-reperfusion+NaHS group had pale infarcted areas in the ischemic cerebral cortex and striatum.The cerebral infarction area of rats in the ischemia-reperfusion group and the ischemia-reperfusion+NaHS group were significantly larger than that in the sham operation group and the NaHS group,while the cerebral infarction area of rats in the ischemia-reperfusion+NaHS group was significantly smaller than that in the ischemia-reperfusion group(P＜0.05).The mNSS scores of rats in the ischemia-reperfusion group and the ischemia-reperfusion+NaHS group were significantly higher than those in the sham operation group and the NaHS group,while the mNSS score of rats in the ischemia-reperfusion+NaHS group was significantly lower than that in the ischemia-reperfusion group(P＜0.05).The relative expression levels of NLRP3 protein in the ischemic cerebral cortex of rats in the ischemia-reperfusion group and the ischemia-reperfusion+NaHS group were significantly higher than those in the sham operation group and the NaHS group,while the relative expression level of NLRP3 protein in the ischemic cerebral cortex of rats in the ischemia-reperfusion+NaHS group was significantly lower than that in the ischemia-reperfusion group(P＜0.05).The levels of IL-1β and IL-18 in the ischemic cerebral cortex of rats in the ischemia-reperfusion group and the ischemia-reperfusion+NaHS group were significantly higher than those in the sham operation group and the NaHS group,while the levels of IL-1β and IL-18 in the ischemic cerebral cortex of rats in the ischemia-reperfusion+NaHS group were significantly lower than those in the ischemia-reperfusion group(P＜0.05).The rats in both sham operation group and NaHS group showed normal morphology of microglia in the ischemic cerebral cortical area.Compared with the sham operation group and the NaHS group,the rats in the ischemia-reperfusion group showed a significant reduction in the protrusion of microglia in the ischemic cerebral cortical area and a significant increase in the brightness of microglial cell bodies,and the cells appeared as clumps,losing their normal morphology,with a higher proportion of activated microglia.Compared with the ischemia-reperfusion group,the rats in the ischemia-reperfusion+NaHS group showed an increase in the number of microglial processes in the ischemic cerebral cortex,with fewer activated microglia and significantly improved morphology.The total numbers of microglia in the ischemic cerebral cortex of rats in the ischemia-reperfusion group and theischemia-reperfusion+NaHS group were significantly lower than those in the sham operation group and the NaHS group,while the total number of microglia in the ischemic cerebral cortex of rats in the ischemia-reperfusion+NaHS group was significantly higher than that in the ischemia-reperfusion group(P＜0.05).Conclusion NaHS can significantly improve brain injury in ischemia-reperfusion rats by inhibiting the inflammatory response and microglial activation induced by NLRP3 and reducing the levels of pro-inflammatory cytokines IL-1β and IL-18.
