The antidepressant activity and molecular mechanisms of Yueju Wan volatile oil were investigated. The Yueju Wan volatile oil was extracted by using supercritical CO_2. Gas chromatography-mass spectrometry(GC-MS) combined with network pharmacology identified 28 chemical constituents in Yueju Wan volatile oil, primarily terpenes and lactones. A total of 123 overlapping targets were associated with depression, including core targets of interleukin-1β(IL-1β), signal transducer and activator of transcription 3(STAT3), and caspase-3(CASP3). These targets were mainly involved in the prolactin, advanced glycation end products/receptor(AGE/RAGE), and phosphoinositide 3-kinase/protein kinase B(PI3K/Akt) signaling pathways. A reserpine-induced depression mouse model was established to evaluate the therapeutic effects and mechanisms of Yueju Wan volatile oil. The effects of Yueju Wan volatile oil on depression-like behavior in mice were evaluated by analyzing body mass, body temperature index, tail suspension immobility time, forced swimming immobility time, and sucrose preference. Hematoxylin-eosin(HE) staining revealed neuronal protection of Yueju Wan volatile oil in the brain of mice. Enzyme-linked immunosorbent assay(ELISA) and Western blot were employed to detect the protein expression of AGEs, IL-1β, phosphorylated PI3K(p-PI3K), Akt, phosphorylated Akt(p-Akt), nuclear factor κB(NF-κB), and brain-derived neurotrophic factor(BDNF). Behavioral evaluation showed that Yueju Wan volatile oil could effectively control the decline of body mass and body temperature of depressed mice, reduce tail suspension and swimming immobility time, and enhance their preference for sucrose. Histopathological examination showed that Yueju Wan volatile oil could alleviate the neuronal damage in CA1 and dentate gyrus(DG) of the hippocampus of mice. ELISA and Western blot results showed that Yueju Wan volatile oil could significantly increase the protein expression levels of PI3K, Akt, and BDNF and significantly decrease the protein expression levels of AGEs, IL-1β, p-PI3K, p-Akt, and NF-κB in the hippocampus of mice. Furthermore, the p-PI3K/PI3K and p-Akt/Akt ratios were significantly decreased at medium and high doses. These findings suggest that the aromatherapy of Yueju Wan volatile oil can significantly improve reserpine-induced depression-like behavior in mice, which may be related to reducing the expression of neuronal membrane protein AGEs, reducing the phosphorylation levels of PI3K and Akt, inhibiting NF-κB entry into the nucleus, and alleviating the release of pro-inflammatory factors and nerve injury.

This study aimed to explore the mechanisms and molecular targets of total flavones of Abelmoschus manihot(TFA) plus empagliflozin(EM) in attenuating diabetic tubulopathy(DT) by targeting mitochondrial homeostasis and pyroptosis-apoptosis-necroptosis(PANoptosis). In the in vivo study, the authors established the DT rat models through a combination of uninephrectomy, administration of streptozotocin via intraperitoneal injections, and exposure to a high-fat diet. Following modeling successfully, the DT rat models received either TFA, EM, TFA+EM, or saline(as a vehicle) by gavage for eight weeks, respectively. In the in vitro study, the authors subjected the NRK52E cells with or without knock-down Z-DNA binding protein 1(ZBP1) to a high-glucose(HG) environment and various treatments including TFA, EM, and TFA+EM. In the in vivo and in vitro studies, The authors investigated the relative characteristics of renal tubular injury and renal tubular epithelial cells damage induced by reactive oxygen species(ROS), analyzed the relative characteristics of renal tubular PANoptosis and ZBP1-mediatted PANoptosis in renal tubular epithelial cells, and compared the relative characteristics of the protein expression levels of marked molecules of mitochondrial fission in the kidneys and mitochondrial homeostasis in renal tubular epithelial cells, respectively. Furthermore, in the network pharmacology study, the authors predicted and screened targets of TFA and EM using HERB and SwissTargetPrediction databases; The screened chemical constituents and targets of TFA and EM were constructed the relative network using Cytoscape 3.7.2 network graphics software; The relative targets of DT were integrated using OMIM and GeneCards databases; The intersecting targets of TFA, EM, and DT were enriched and analyzed signaling pathways by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG) software using DAVID database. In vivo study results showed that TFA+EM could improve renal tubular injury, the protein expression levels and characteristics of key signaling molecules in PANoptosis pathway in the kidneys, and the protein expression levels of marked molecules of mitochondrial fission in the kidneys. And that, the ameliorative effects in vivo of TFA+EM were both superior to TFA or EM. Network pharmacology study results showed that TFA+EM treated DT by regulating the PANoptosis signaling pathway. In vitro study results showed that TFA+EM could improve ROS-induced cell injury, ZBP1-mediatted PANoptosis, and mitochondrial homeostasis in renal tubular epithelial cells under a state of HG, including the protein expression levels of marked molecules of mitochondrial fission, mitochondrial ultrastructure, and membrane potential level. And that, the ameliorative effects in vitro of TFA+EM were both superior to TFA or EM. More importantly, using the NRK52E cells with knock-down ZBP1, the authors found that, indeed, ZBP1 was mediated PANoptosis in renal tubular epithelial cells as an upstream factor. In addition, TFA+EM could regulate the protein expression levels of marked signaling molecules of PANoptosis by targeting ZBP1. In summary, this study clarified that TFA+EM, different from TFA or EM, could attenuate DT with multiple targets by ameliorating mitochondrial homeostasis and inhibiting ZBP1-mediated PANoptosis. These findings provide the clear pharmacological evidence for the clinical treatment of DT with a novel strategy of TFA+EM, which is named "coordinated traditional Chinese and western medicine".

This study investigated the role of the nuclear factor of activated T cells c3 (NFATc3) in vascular smooth muscle cells (VSMCs) during aortic aneurysm and dissection (AAD) progression and the underlying molecular mechanisms. Cytoplasmic and nuclear NFATc3 levels were elevated in human and mouse AAD. VSMC-NFATc3 deletion reduced thoracic AAD (TAAD) and abdominal aortic aneurysm (AAA) progression in mice, contrary to VSMC-NFATc3 overexpression. VSMC-NFATc3 deletion reduced extracellular matrix (ECM) degradation and maintained the VSMC contractile phenotype. Nuclear NFATc3 targeted and transcriptionally upregulated matrix metalloproteinase 9 (MMP9) and MMP2, promoting ECM degradation and AAD development. NFATc3 promoted VSMC phenotypic switching by binding to eukaryotic elongation factor 2 (eEF2) and inhibiting its phosphorylation in the VSMC cytoplasm. Restoring eEF2 reversed the beneficial effects in VSMC-specific NFATc3-knockout mice. Cabamiquine-targets eEF2 and inhibits protein synthesis-inhibited AAD development and progression in VSMC-NFATc3-overexpressing mice. VSMC-NFATc3 promoted VSMC switch and ECM degradation while exacerbating AAD development, making it a novel potential therapeutic target for preventing and treating AAD.

Objective To analyze the risk factors for gait disorder in patients with developmental dysplasia of the hip(DDH)after total hip replacement.Methods Sixty DDH patients who underwent total hip replacement at The Second People's Hospital of Kunshan from August 2018 to August 2023 were selected as research objects.Of them,19 patients with gait disorders were assigned to observation group,and 41 without gait disorders were taken as control group.Univariate and multivariate logistic regression analyses were conducted to identify the risk factors for gait disorders in DDH patients after total hip replacement.Results There was no significant difference in the gender,age,disease duration,place of residence,educational level,American Society of Anesthesiologists(ASA)grade,surgical time,intraoperative blood loss,Tonnis classification,or symmetrical skin lines on lower limbs between the two groups(P>0.05).But there were significant differences in terms of equal length of lower limbs,anterior pelvic tilt,cerebral small vessel disease,Parkinson disease,and peripheral nerve injury in lower limbs between the two groups(P<0.05).Equal length of lower limbs,anterior pelvic tilt,cerebral small vessel disease,Parkinson disease,and peripheral nerve injury in lower limbs were risk factors for gait disorders in DDH patients after total hip replacement(P<0.05).Conclusion The occurrence of gait disorders is related to the equal length of lower limbs,anterior pelvic tilt,cerebral small vessel disease,Parkinson disease,and peripheral nerve injury in lower limbs in DDH patients after total hip replacement.Symptomatic treatment should be given timely so as to prevent gait disorders and improve the prognosis.

Objective To study the application of mesoporous silica nanoparticle(MSN)as drug carriers in the treatment of osteoarthritis(OA).Methods Core-cone structured MSN(MSN-CC)was synthesized by sol-gel method,modified by polyethyleneimine(PEI),and loaded with hyaluronic acid synthase 2(HAS2).Forty OA model rats were randomly assigned to OA group,MSN-CC-PEI group,hyaluronic acid(HA)group,or MSN-CC-PEI-HAS2 group.Ten healthy rats were assigned to control group.Normal saline 100 μL was injected into the knee joint in the control group and OA group.MSN-CC-PEI 100 μL,HA solution 100 μL,and MSN-CC-PEI-HAS2 100 μL were injected in MSN-CC-PEI group,HA group,and MSN-CC-PEI-HAS2 group,respectively.The levels of HA,interleukin-1β(IL-1β),and prostaglandin E2(PGE2)in the joint effusion and the foot swelling degree were measured at 1,2,and 3 weeks after injection.Results HA level in the MSN-CC-PEI-HAS2 group was significantly lower than that in the HA group at 1 week after intervention(P<0.05),while HA level in the MSN-CC-PEI-HAS2 group was significantly higher than that in the HA group at 2 and 3 weeks after intervention(P<0.05).With the time going on,HA level in the HA group was gradually decreased(P<0.05),but HA level in the MSN-CC-PEI-HAS2 group was gradually increased(P<0.05).At 1 and 2 weeks after intervention,compared with the HA group,IL-1β,PGE2 and foot swelling degree in the MSN-CC-PEI-HAS2 group were increased(P<0.05).At 3 weeks after intervention,compared with the HA group,IL-1β,PGE2 and foot swelling degree in the MSN-CC-PEI-HAS2 group were decreased(P<0.05).With the time going on,IL-1β,PGE2 and foot swelling degree in the HA group and MSN-CC-PEI-HAS2 group were gradually decreased(P<0.05).Conclusion MSN carrier can stably stimulate the secretion of endogenous HA,reduce the inflammatory response within joint cavity of OA rats,and improve the joint morphology and soft tissue pathological changes.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

To evaluate the efficacy and safety of dye-free submucosal injection solution for gastric endoscopic submucosal dissection (ESD), a retrospective cohort study was performed on data of inpatients with early gastric cancer and precancerous lesions who underwent ESD at the Digestive Endoscopy Center of Jiangsu Province Hospital of Traditional Chinese Medicine from January to December 2020. Cases were divided into dye-free submucosal injection solution group (the observation group) and dye-containing solution group (the control group). A total of 108 cases met the eligibility criteria for analysis (39 VS 69). Baseline characteristics were comparable between the two groups ( P>0.05). Compared with the control group, the observation group showed similar median procedure time (30.5 min VS 35.0 min), median dissection speed (0.3 cm2/min VS 0.4 cm2/min), mean volume of injection solution used (39.2 mL VS 38.8 mL), en bloc resection rate [100.0% (39/39) VS 98.6% (68/69)], and curative resection rate [97.4% (38/39) VS 97.1% (67/69)] (all P>0.05). Postoperative stay was 3.0±0.8 days in the observation group and 3.2±0.8 days in the control group ( t=-0.908, P=0.378). Delayed bleeding occurred in 3 (7.7%) patients VS 2 (2.9%) patients ( P=0.349), and postoperative infection occurred in 3 (7.7%) patients VS 8 (11.6%) patients ( P=0.743), respectively. In gastric ESD, dye-free submucosal injection solution demonstrates efficacy comparable with dye-containing solution and does not appreciably increase the incidence of intraoperative or postoperative complications.

Objective:To investigate whether changes in CT pulmonary angiography (CTPA) parameters before and after balloon pulmonary angioplasty (BPA) are correlated with treatment effects in patients with chronic thromboembolic pulmonary hypertension (CTEPH).Methods:A retrospective study was conducted, including patients with CTEPH who underwent BPA treatment at Beijing Anzhen Hospital from November 2021 to Febbruary 2024. Clinical data and CTPA parameters were analyzed before the initial BPA session and at least 6 months after the final BPA session. Clinical data included WHO functional class, 6-minute walk distance (6MWD), and plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) levels. The CTPA parameters included the widest diameter of the pulmonary artery diameter (dPA), ascending aorta diameter (dAA), the widest transverse diameter of the right atrium (dRA), the widest short-axis diameter of the right ventricle (dRV), the widest short-axis diameter of the left ventricle (dLV), and the diameter of right ventricular free wall thickness(dRVW). Multiple linear regression was applied to identify variables associated with the decrease in mean pulmonary artery pressure (mPAP) among the CTPA parameters.Results:All CTEPH patients underwent a total of 115 BPA treatments. Postoperatively, the WHO functional class of the patients improved compared to preoperative levels ( χ2=5.01, P<0.001), 6MWD improved ( t=4.50, P<0.001), and NT-proBNP levels decreased ( Z=4.47, P<0.001). Hemodynamic parameters, including mPAP, pulmonary vascular resistance, cardiac output, and cardiac index, were significantly improved postoperatively (all P<0.001). CTPA-related parameters, including dPA, dRA, dRV, dRVW, dPA/dAA, dRV/dLV, and dRA/dPA, significantly decreased compared to preoperative values (all P<0.001). Multiple linear regression analysis showed that the decrease in dPA ( β=0.314, P=0.037) and dRA ( β=0.334, P=0.046) were significantly correlated with the improvement in mPAP. Conclusions:Exercise tolerance, hemodynamics, and CTPA parameters in patients with CTEPH significantly improved after BPA treatment. The decrease in dPA and dRA were significantly correlated with the improvement in mPAP, suggesting that CTPA is a potentially novel, objective, effective, and noninvasive method for evaluating the therapeutic efficacy of BPA.
