OBJECTIVES: Urinary calculi are characterized by a high recurrence rate, and patients' adherence to self-management after discharge directly affects health outcomes. Traditional offline follow-up models often face problems such as poor compliance and uneven allocation of medical resources, making it difficult to meet individualized health management needs. Remote follow-up provides a novel solution to optimize long-term management, improve health literacy, and enhance clinical outcomes. This study aims to evaluate the effect of remote follow-up under an intelligent medical collaborative model on quality of life and health-promoting lifestyle in patients with urinary calculi, and to assess its short-term impact on clinical outcomes. METHODS: A total of 118 patients with urinary calculi admitted to a tertiary hospital in Hunan Province between August and November 2024 were recruited and randomly assigned to a control group (n=59) or an intervention group (n=59). The control group received routine departmental follow-up, while the intervention group underwent remote follow-up based on an intelligent medical collaborative model for one month. Assessments were conducted before discharge (T0), 15 days after discharge (T1), and one month after discharge (T2), using the Wisconsin Stone Quality of Life Questionnaire and the Health-Promoting Lifestyle Profile. At T2, the incidence of forgotten ureteral stents (FUS), ureteral stent-related complications, unplanned readmissions, and patient satisfaction were evaluated. RESULTS: No significant differences were observed between groups at T0 in baseline characteristics or outcome measures (all P>0.05). At T1 and T2, the intervention group had significantly higher health-related quality of life scores than the control group (P<0.05). Generalized estimating equation (GEE) analysis showed significant between-group effects (Wald's χ²=22.961, P<0.001), time effects (Wald's χ²=23.065, P<0.001), and interaction effects (Wald's χ²=6.930, P<0.05). Similarly, at T1 and T2, the intervention group scored significantly higher on health-promoting lifestyle than the control group (P<0.05), with significant between-group effects (Wald's χ²=22.936, P<0.001), time effects (Wald's χ²=10.694, P<0.001), and interaction effects (Wald's χ²=18.921, P<0.05). No significant differences were found between groups in the incidence of FUS, ureteral stent-related complications, or unplanned readmissions (all P>0.05). Patient satisfaction was significantly higher in the intervention group (t=4.089, P<0.001). CONCLUSIONS Remote follow-up under an intelligent medical collaborative model helps improve quality of life, promote health-oriented lifestyles, and enhance patient satisfaction among individuals with urinary calculi.

BACKGROUND:A pathophysiological feature of septic organ failure is endothelial dysfunction in sepsis(EDS).The physiological and pathological mechanism of sepsis is considered to be vascular leakage caused by endothelial dysfunction.These pathological changes lead to systemic organ injury.However,an analysis using bibliometric methods has not yet been conducted in the field of EDS.This study was conducted to provide an overview of knowledge structure and research trends in the field of EDS. METHODS:Based on previous research,a literature search was performed in the Web of Science Core Collection(WoSCC)for publications associated with EDS published between the year 2003 and 2023.Various types of data from the publications,such as citation frequency,authorship,keywords and highly cited articles,were extracted.The"Create Citation Report"feature in the WoSCC was employed to calculate the Hirsch index(h-index)and average citations per item(ACI)of authors,institutions,and countries.To conduct bibliometric and visualization analyses,three bibliometric tools were used,including R-bibliometrix,CiteSpace(co-citation analysis of references),and VOSviewer(co-authorship analysis of institutions,co-authorship analysis of authors,co-occurrence analysis of keywords). RESULTS:After excluding invalid records,the study finaly included 4,536 publications with 135,386 citations.Most of these publications originated in the USA,China,Germany,Canada,and Japan.Harvard University emerged as the most prolific institution,while professor Jong-Sup Bae and his research team at Kyungpook National University emerged as authors with the greatest influence.The"protein C","tissue factor","thrombin","glycocalyx","acute kidney injury","syndecan-1"and"biomarker"were identified as prominent areas of research.Future research may focus on molecular mechanisms(such as as vascular endothelial[VE]-cadherin regulation)and therapeutic interventions to enhance endothelial repair and function. CONCLUSION:Our findings show a growing interest in EDS research.Key areas for future research include signaling pathways,molecular mechanisms,endothelial repair,and interactions between endothelial cells and other cell types in sepsis.

Objective: This study aimed to determine the predictive performance of non-contrast CT (NCCT) signs for hemorrhagic growth after intracerebral hemorrhage (ICH) when stratified by onset-to-imaging time (OIT). Materials and Methods: 1488 supratentorial ICH within 6 h of onset were consecutively recruited from six centers between January 2018 and August 2022. NCCT signs were classified according to density (hypodensities, swirl sign, black hole sign, blend sign, fluid level, and heterogeneous density) and shape (island sign, satellite sign, and irregular shape) features. Multivariable logistic regression was used to evaluate the association between NCCT signs and three types of hemorrhagic growth: hematoma expansion (HE), intraventricular hemorrhage growth (IVHG), and revised HE (RHE). The performance of the NCCT signs was evaluated using the positive predictive value (PPV) stratified by OIT. Results: Multivariable analysis showed that hypodensities were an independent predictor of HE (adjusted odds ratio [95% confidence interval] of 7.99 [4.87–13.40]), IVHG (3.64 [2.15–6.24]), and RHE (7.90 [4.93–12.90]). Similarly, OIT (for a 1-h increase) was an independent inverse predictor of HE (0.59 [0.52–0.66]), IVHG (0.72 [0.64–0.81]), and RHE (0.61 [0.54– 0.67]). Blend and island signs were independently associated with HE and RHE (10.60 [7.36–15.30] and 10.10 [7.10–14.60], respectively, for the blend sign and 2.75 [1.64–4.67] and 2.62 [1.60–4.30], respectively, for the island sign). Hypodensities demonstrated low PPVs of 0.41 (110/269) or lower for IVHG when stratified by OIT. When OIT was ≤ 2 h, the PPVs of hypodensities, blend sign, and island sign for RHE were 0.80 (215/269), 0.90 (142/157), and 0.83 (103/124), respectively. Conclusion Hypodensities, blend sign, and island sign were the best NCCT predictors of RHE when OIT was ≤ 2 h. NCCT signs may assist in earlier recognition of the risk of hemorrhagic growth and guide early intervention to prevent neurological deterioration resulting from hemorrhagic growth.

OBJECTIVES: Non-small cell lung cancer (NSCLC) accounts for 85% of all lung cancer, with highmorbidity and mortality rate. Nove drug development for NSCLC is urgently needed.This study aims to investigate the activity of lathyrol derivatives and the mechanism for its inhibitory effect on the growth of NSCLC cells. METHODS: Three lathyrol derivatives were synthesized from lathyrol and their structures were verified by nuclear magnetic resonance. MTT assay was used to detect the effects of the lathyrol derivatives on the proliferation activity of NSCLC cells (A549 and H1299 cells), and the compound with the best activity was selected for subsequent experiments. Colony forming assay, wound-healing assay, and transwell assay were applied to detect in vitro cell proliferation, migration and invasion ability in A549 and H1299 cells, respectively. Quantitative real-time RT-PCR and Western blotting were performed to detect mRNA and protein levels of E-cadherin, N-cadherin, β-catenin, and MMP2 in A549 cells, respectively. RESULTS: Three lathyrol derivatives inhibited the growth of A549 and H1299 cells in a dose-dependent manner, and they showed a weak inhibitory effect on normal cells Beas-2B and 16HBE, indicating that they possessed certain selective toxic effects. Therefore, C-5 benzoylated lathyrol with the best activity was selected as the ideal drug for the subsequent experiments. Compared with the control group, the number and size of cell clusters in the treatment group of A549 and H1299 cells were significantly decreased, the relative mobility were significantly decreased, and the number of invaded cells were significantly decreased (all P<0.05), indicating that the in vitro cell proliferation, migration and invasion ability were decreased. The mRNA levels of integrin α2, integrin β1, MMP2, MMP9, β-catenin, and N-cadherin were decreased, while the expression of E-cadherin was increased (all P<0.05). The protein levels of N-cadherin, β-catenin, MMP2, and integrin αV were decreased, while the expression of E-cadherin was increased (all P<0.05). CONCLUSIONS The lathyrol derivatives synthesized in this study possess good inhibitory activity against NSCLC. Among them, C-5 benzoylated lathyrol significantly inhibits the proliferation, migration, and invasion ability of NSCLC cells in vitro through regulating the process of epithelial-mesenchymal transition.

To investigate the antitumor activity induced by Ganoderma lucidum spore oil on different tumor cells. Human hepatoma cells(HepG2), human non-small cells lung cancer cells(A549)and human colon cancer cells(HCT116)were selected and tested. Cell viability was determined by MTT assay. Western blot analysis was performed to measure the expression of NF-κB and Caspase-3 activity in order to elucidate the mechanism of apoptotic activity caused by Ganoderma lucidum spore oil and to screen out the most sensitive cancer cell lines to Ganoderma lucidum spore oil. MTT assay demonstrated that Ganoderma lucidum spore oil had a strong inhibitory effect on the growth of three cancer cell lines. Among these cells, A549 cells were most sensitive to Ganoderma lucidum spore oil, followed by HepG2 cells and then by HCT116 cells. The results of Western blot showed that Ganoderma lucidum spore oil could promote the activation of NF-κB pathway, and that the activation of NF-κB signaling pathway in cancer cells treated by Ganoderma lucidum spore oil was stronger in A549 cells, HepG2 cells, HCT116 cells respectively. The detection of Caspase-3 activity showed that ganoderma spore oil could activate Caspase-3 dependent apoptosis pathways, which was more important in A549 cells, HepG2 cells and HCT116 cells. This study found that Ganoderma lucidum spore oil had inhibitory effects on A549, HepG2 and HCT116 cells growth and that its antitumor activity was in time-dose dependence. The mechanism may be related to the activation of NF-κB pathway and the Caspase-3 apoptotic pathway, which could accelerate apoptosis and necrosis of tumor cells. Among the three kinds of cancer cells, A549 cells was most sensitive to Ganoderma lucidum spore oil, followed by the HepG2 cells, and then by HCT116 cells.

In this study,the effects of hyperosmolality on the expression of urea transporter A2 (UTA2) and aquaporin 2 (AQP2) were investigated in transfected immortalized mouse medullary collecting duct (mIMCD3) cell line.AQP2-GFP-pCMV6 and UTA2-GFP-pCMV6 plasmids were stably transfected into mIMCD3 cells respectively.Transfected mIMCD3 and control cells were cultured in different hypertonic media,which were made by NaCl alone,urea alone,or an equiosmolar mixture of NaCl and urea.The mRNA and protein expression of AQP2 was elevated by the stimulation of NaCl alone,urea alone and NaCl plus urea in AQP2-mIMCD3 cells; whereas NaCl alone and NaCl plus urea rather than urea alone increased the mRNA and protein expression of UTA2 in UTA2-mIMCD3 cells,and all the expression presented an osmolality-dependent manner.Moreover,the mRNA and protein expression of UTA2 rather than AQP2 was found to be synergistically up-regulated by a combination of NaC1 and urea in mIMCD3 cells.It is concluded that NaC1 and urea synergistically induce the expression of UTA2 rather than AQP2 in mIMCD3 cells,and hyperosmolality probably mediates the expression of AQP2 and UTA2 through different mechanisms.
