OBJECTIVE To study the pharmacokinetic characteristics of antidepressant active components from Jiaotai pills in healthy subjects. METHODS Eight healthy subjects （3 males and 5 females） were recruited and given a single oral dose of 8.55 g of Jiaotai pills. Venous blood samples were collected before administration （0 h） and at intervals from 0.25 to 36.0 hours post- administration. After treating the plasma samples with protein precipitation， the blood concentrations of the antidepressant active ingredients （coptisine， berberine， magnoflorine， and palmatine） in Jiaotai pills were determined using liquid chromatography- tandem mass spectrometry （LC-MS/MS） method. DAS 2.0 software was employed to calculate the pharmacokinetic parameters of healthy subjects [half-life （t1/2）， peak concentration （cmax）， time to peak concentration （tmax）， area under the concentration-time curve （AUC）， and mean residence time （MRT）] using a non-compartmental model. RESULTS After healthy subjects took Jiaotai pills， the drug-time curve of the four antidepressant active ingredients conforms to a two-compartment model and tmax values were similar， with all reaching peak blood concentrations within 2.00 to 4.00 hours post-administration. However， the t1/2 and MRT of coptisine and berberine were significantly longer than that of magnoflorine and palmatine. There were also significant differences in the AUC and cmax among the four antidepressant active ingredients， with magnoflorine exhibiting markedly higher AUC0-t and cmax compared to the other three components. CONCLUSIONS In this study，LC-MS/MS is used to analyze the pharmacokinetic characteristics of the antidepressant active ingredients from Jiaotai pills in healthy subjects， can provide valuable references for the clinical application of Jiaotai pills.

BACKGROUND:Type 2 diabetes mellitus is a secondary causative factor for osteoporosis.As highly heterogeneous innate immune cells,macrophages may be polarized in a hyperglycemic environment,which affects osteogenesis-angiogenesis coupling.This may be a research target for improving bone quality in patients with type 2 diabetic osteoporosis.OBJECTIVE:To explore the role of modulating macrophage M1/M2 polarization to influence osteogenesis-angiogenesis coupling in type 2 diabetic osteoporosis and to summarize the effects of commonly used anti-glucose and anti-osteoporosis drugs and bone biorepair materials on bone osteogenesis-angiogenesis coupling by regulating macrophage M1/M2 polarization.METHODS:The keywords of"macrophage polarization,type 2 diabetes,osteoporosis,osteogenesis-angiogenesis coupling"in Chinese and"macrophages,macrophage polarization,osteogenesis-angiogenesis coupling"in English were used to search for relevant literature in CNKI and PubMed,respectively.Seventy-nine pieces of literature were screened and analyzed.RESULTS AND CONCLUSION:(1)Type 2 diabetes mellitus causes the body to be in a hyperglycemic environment and increases the secretion of inflammatory-related factors in the body,which promotes macrophage polarization towards M1 and decreases the number of M2 macrophages.(2)In type 2 diabetes,promoting M2 macrophage polarization is beneficial for osteogenesis-angiogenesis coupling.(3)Some anti-glycemic drugs,active ingredients in traditional Chinese medicine and bone biorepair materials can improve type 2 diabetic osteoporosis by regulating macrophage M1/M2 polarization,reducing M1/M2 ratio,and promoting osteogenesis-angiogenesis coupling.

Purpose: The aim of this study is to determine the impact of solute carrier family 3 member 2 (SLC3A2) on the malignant phenotype of gliomas and its role in regulating ferroptosis sensitivity. Materials and Methods: The malignant phenotype of glioma was assessed by cell proliferation assay, colony formation assay, EdU assay, wound healing, and Transwell experiments. We further validated the impact of reduced SLC3A2 expression on the sensitivity to ferroptosis in glioma cells through Cell Counting Kit-8 assays, flow cytometry, western blotting, and transmission electron microscopy. Western blot was used to explore how SLC3A2 affects glioma sensitivity to ferroptosis through the AKT/NF-E2-related factor 2 (NRF2)/glutathione peroxidase 4 (GPX4) axis. By establishing a subcutaneous xenograft tumor model in BALB/c-nude mice, we investigated the growth of tumors following the knockout of SLC3A2 in glioma cells. Results: Downregulation of SLC3A2 suppressed the malignant phenotype of glioma by blocking the cell cycle and epithelial-mesenchymal transition processes. On the other hand, loss of SLC3A2 not only downregulated SLC7A11 but also prevented the activation of the AKT/NRF2/GPX4 axis. These lead to increased accumulation of reactive oxygen species and lipid peroxides, ultimately enhancing the susceptibility of glioma to ferroptosis. Conclusion Our findings suggest that SLC3A2 is an oncogene in gliomas, promoting their occurrence and development. It plays a critical role in ferroptosis resistance through the AKT/NRF2/GPX4 axis.

Objective:To analyze and clarify the meaning of the concept of self-advocacy among patients with chronic diseases using the Rodgers evolutionary concept analysis method.Methods:A systematic search was conducted in databases including PubMed, Web of Science, Cochrane Library, CINAHL, Embase, Medline, VIP, Wanfang, the China National Knowledge Infrastructure, and Chinese Biomedical Literature Database for studies related to self-advocacy in chronic disease patients from February 1, 1992, to June 30, 2024. The Rodgers evolutionary concept analysis method was applied to analyze the selected literature.Results:A total of 72 articles were included in this study. The concept attributes of self-advocacy in chronic disease patients were identified as cognitive awareness, self-action, and resource integration.

The outcomes covered improved symptom management, adherence to treatment plans, enhanced nursing and quality of life, and reduced demand for healthcare. The measurement tools used were the Patient Self-Advocacy Scale, Self-Advocacy Scale, Elderly Safety Advocacy Empowerment Scale, and Female Cancer Patient Self-Advocacy Scale.Conclusions:The conceptual attributes of self-advocacy in chronic disease patients were clarified through the Rodgers evolutionary concept analysis method. Future research can combine quantitative and qualitative studies to further explore the significance of self-advocacy in patients with chronic diseases.

Objective This study estimated the disability burden of diabetes attributable to smoking,alcohol consumption,and obesity among oilemployees.It provides a comprehensive assessment of the major chronic disease burden attributable to these factors,offering a scientific basis for risk factor prevention and control.Methods Years lived with disability(YLD)was used as the burden indicator for diabetes among oilemployees.Based on the counterfactual attribution method within the comparative risk assessment framework,the population attributable fraction(PAF)for diabetes due to different behavioral risk factors was estimated.The attributable risk was calculated using the exposure rates of risk factors and their relative risk(RR)associated with related diseases,which was then used to compute the attributable YLD.A proportional change model was used to predict the YLD rates of chronic diseases among oilfield employees in 2030 under different risk factor control scenarios,calculating the YLD that could be avoided through risk factor control.Results According to the PAF calculated using the proportional risk assessment framework,the attributable burden of diabetes due to smoking,alcohol consumption,and obesity was higher in male employees than in females,with older females having a higher attributable burden,while middle-aged and young males had a higher burden.For males,achieving control targets for smoking,alcohol consumption,and obesity by 2030 would result in a decrease in diabetes YLD rates by 17.53％,3.52％,and 56.20％,respectively,compared to natural trends.For females,achieving these targets would decrease YLD rates by 1.18％,1.32％,and 26.47％,respectively.The largest decrease in YLD rates for both male and female employees occurred under the obesity control scenario.Conclusion By studying health risk factors and disease burdens among employees,oil companies can develop and implement targeted health management plans,enhancing employee health protection and improving work efficiency and productivity.

Objective:To explore the prominent manifestations and internal associations of the overuse of short-form videos,inattention,and school refusal behavior in junior high school students.Methods:A survey was conducted among 1 106 junior high school students,utilizing the Short-form Video APP Overuse Scale,the Inatten-tion subscale of the Swanson,Nolan,and Pelham Rating Scale(SNAP-Ⅳ),and the School Refusal Behavior Ques-tionnaire to assess the extent of short-form video overuse,inattention,and school refusal behavior.By using the R language for network analysis,the core nodes of individual networks and the bridge nodes connecting the combined networks were analyzed,and the structural differences in networks across genders and grades were compared.Re-sults:The core nodes of the network pertaining to overuse of short-form video,inattention,and school refusal behav-ior were"Using short videos enhances connection with others"(expected influence value=1.03),"easily distract-ed"(expected influence value=1.99),and"school alienation"(expected influence value=0.83).The bridge nodes in the combined network were"defiant behavior"(bridge expected influence value=0.69)and"difficulty sustaining mental activities"(bridge expected influence value=0.47).Analysis of network structure differences i-dentified that the core nodes within the combined networks of the first,second,and third grades of junior high school students were respectively"prioritizing short videos over other activities","defiant behavior",and"academic aptitude".Conclusion:Junior high school students exhibiting overuse of short videos,inattention,or school refusal behavior are characterized by enhanced social connectivity through platforms such as short video apps,a propensity for distraction,and feelings of school alienation,respectively.When these three behaviors coexist,the most salient related factor is oppositional behavior,coupled with difficulties in sustaining cognitive tasks and maintaining con-centration.

Objective:To explore the trajectory and influencing factors of dietary adherence at different periods in patients with newly diagnosed type 2 diabetes mellitus (T2DM), so as to provide a reference for dietary management at different periods in patients with newly diagnosed T2DM.Methods:Convenience sampling was used to select 180 patients with newly diagnosed T2DM who attended Diabetes Clinics in three ClassⅢ Grade A hospitals in Henan Province from May 2021 to May 2023 for the study. Patients were surveyed on the day of diagnosis (T1) and at 3 months (T2), 6 months (T3), and 12 months (T4) after diagnosis using General Information Questionnaire, Decisional Balance Scale for Diabetes Diet, Diabetes Distress Scale, Family APGAR Index, and Influence Factors of Dietary Behavior Compliance Scale for Patients with T2DM (T2DM-CFIDBS), respectively. Pearson correlation was used to test the correlation between dietary adherence, diabetes diet decisional balance, diabetes distress, and family care in patients with newly diagnosed T2DM. Multiple linear regression was used to analyze the factors influencing dietary adherence at each time point in patients with newly diagnosed T2DM. A total of 180 questionnaires were distributed, and 162 valid questionnaires were recovered, with a valid recovery rate of 90.00% (162/180) .Results:CFIDBS scores of patients with newly diagnosed T2DM at the four time points were (69.14±9.97), (61.98±8.82), (60.09±8.97), and (63.29±9.98), respectively. Body mass index and diabetes distress had an impact on patients' dietary adherence at T1, T2, T3, and T4 ( P<0.05). Perceptual deficits had an impact on dietary adherence at T1, T2, and T3 ( P<0.05). Family care had an impact on dietary adherence at T1 and T2 ( P<0.05). Perceived benefit had an impact on dietary adherence only at the T3 ( P<0.05). Education level and work status only had an impact on dietary adherence at the T4 ( P<0.05). All of these differences were statistically significant. Conclusions:Dietary adherence in patients with newly diagnosed T2DM shows a trend of decreasing and then increasing over time, and there are differences in the influencing factors at different times. Healthcare professionals should pay attention to the trajectory and influencing factors of dietary adherence in patients with newly diagnosed T2DM, and develop targeted interventions to improve patients' dietary adherence and diabetes prognosis.

Intervertebral disc degeneration (IDD) is largely attributed to impaired endogenous repair. Nucleus pulposus-derived stem cells (NPSCs) senescence leads to endogenous repair failure. Small extracellular vesicles/exosomes derived from mesenchymal stem cells (mExo) have shown great therapeutic potential in IDD, while whether mExo could alleviate NPSCs senescence and its mechanisms remained unknown. We established a compression-induced NPSCs senescence model and rat IDD models to evaluate the therapeutic efficiency of mExo and investigate the mechanisms. We found that mExo significantly alleviated NPSCs senescence and promoted disc regeneration while knocking down thioredoxin (TXN) impaired the protective effects of mExo. TXN was bound to various endosomal sorting complex required for transport (ESCRT) proteins. Autocrine motility factor receptor (AMFR) mediated TXN K63 ubiquitination to promote the binding of TXN on ESCRT proteins and sorting of TXN into mExo. Knocking down exosomal TXN inhibited the transcriptional activity of nuclear factor erythroid 2-related factor 2 (NRF2) and activator protein 1 (AP-1). NRF2 and AP-1 inhibition reduced endogenous TXN production that was promoted by exosomal TXN. Inhibition of NRF2 in vivo diminished the anti-senescence and regenerative effects of mExo. Conclusively, AMFR-mediated TXN ubiquitination promoted the sorting of TXN into mExo, allowing exosomal TXN to promote endogenous TXN production in NPSCs via TXN/NRF2/AP-1 feed-forward circuit to alleviate NPSCs senescence and disc degeneration.
