Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.

Exosomal circular RNA (circRNAs) are pivotal in cancer biology, and tumor pathophysiology. These stable, non-coding RNAs encapsulated in exosomes participated in cancer progression, tumor growth, metastasis, drug sensitivity and the tumor microenvironment (TME). Their presence in bodily fluids positions them as potential non-invasive biomarkers, revealing the molecular dynamics of cancers. Research in exosomal circRNAs is reshaping our understanding of neoplastic intercellular communication. Exploiting the natural properties of exosomes for targeted drug delivery and disrupting circRNA-mediated pro-tumorigenic signaling can develop new treatment modalities. Therefore, ongoing exploration of exosomal circRNAs in cancer research is poised to revolutionize clinical management of cancer. This emerging field offers hope for significant breakthroughs in cancer care. This review underscores the critical role of exosomal circRNAs in cancer biology and drug resistance, highlighting their potential as non-invasive biomarkers and therapeutic targets that could transform the clinical management of cancer.

Objective To propose a heart sound segmentation method based on multi-feature fusion network. Methods Data were obtained from the CinC/PhysioNet 2016 Challenge dataset (a total of 3 153 recordings from 764 patients, about 91.93% of whom were male, with an average age of 30.36 years). Firstly the features were extracted in time domain and time-frequency domain respectively, and reduced redundant features by feature dimensionality reduction. Then, we selected optimal features separately from the two feature spaces that performed best through feature selection. Next, the multi-feature fusion was completed through multi-scale dilated convolution, cooperative fusion, and channel attention mechanism. Finally, the fused features were fed into a bidirectional gated recurrent unit (BiGRU) network to heart sound segmentation results. Results The proposed method achieved precision, recall and F1 score of 96.70%, 96.99%, and 96.84% respectively. Conclusion The multi-feature fusion network proposed in this study has better heart sound segmentation performance, which can provide high-accuracy heart sound segmentation technology support for the design of automatic analysis of heart diseases based on heart sounds.

ObjectiveTo explore the mechanisms of Astragali Radix-Curcumae Rhizoma (HQ-EZ) in alleviating hypercoagulability and inhibiting tumor growth and metastasis by modulating the formation of neutrophil extracellular traps (NETs) via the complement component 5a (C5a)/C5a receptor (C5aR) pathway. MethodForty male C57BL/6 mice were randomized into four groups: Blank, model, HQ-EZ (8.2 g·kg-1), and PMX53 (1 mg·kg-1). The mouse model of Lewis lung cancer was established in other three groups except the blank group. Mice were administrated with corresponding drugs from day 3 after modeling. Specifically, the HQ-EZ decoction was administrated for 14 consecutive days, while intraperitoneal injection of PMX53 was implemented on days 3, 6, 9, 12, and 15. Mouse body weight and tumor diameter were measured every two days. On the next day of the last administration, lung microCT was performed to observe the tumor metastasis in vivo. Blood samples were collected from the eyeball after anesthetization, and tumor and lungs were collected after the mice were sacrificed. Tumor weight was measured to calculate the tumor growth inhibitory rate. Enzyme-linked immunosorbent assay was employed to measure the levels of C5a, neutrophil elastase (NE), citrullinated histone-H3 (Cit-H3), myeloperoxidase (MPO), matrix metallopeptidase-9 (MMP-9), NETs, von Willebrand Factor (vWF), tissue factor (TF), and P-selectin in the serum and tumor tissue. Terminal-deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling was conducted to assess apoptosis in the tumor tissue. Hematoxylin-eosin staining was conducted to observe lung metastasis, and immunofluorescence (IF) was employed to observe the expression of NETs in the tumor tissue. Western blot was employed to determine the protein levels of C5aR, MPO, and Cit-H3 in the tumor tissue. ResultCompared with the blank group, the model group had nodules in the lung, increased areas with low X-ray transmittance, appearance of nodular foci and multiple hemorrhagic foci in the lungs, and darkening lung color. Furthermore, the modeling elevated the serum levels of C5a, NETs and related proteins, vWF, TF, and P-selectin (P<0.01). Compared with the model group, HQ-EZ and PMX53 reduced the lung metastases, areas with low X-ray transmittance, and nodules in the lungs and lightened the lung color. Compared with the model group, the two drug intervention groups showed flat tumor growth curves, decreased tumor weight (P<0.01), increased apoptosis of tumor cells (P<0.01), lowered levels of C5a, NETs and related proteins, vWF, TF, and P-selectin both in the serum and tumor tissue (P<0.05), and down-regulated protein levels of C5aR, MPO, and Cit-H3 (P<0.05). ConclusionHQ-EZ inhibited the expression of NETs by suppressing the C5a/C5aR pathway, thereby alleviating hypercoagulability and inhibiting tumor growth and metastasis.

AIM:To investigate the effects of overexpressing α-Klotho(KL)in RAW264.7 cells stimulated by oxidative stress on the proliferation, migration, tube-formation and tight junction of human umbilical vein endothelial cells(HUVECs).METHODS:RAW264.7 cells were categorized into control, 4-hydroxynonenal(4HNE), and 4HNE+KL groups, with F4/80 expression assessed via immunofluorescence staining. Three groups of conditional media were prepared for HUVECs and culture divided into Mø-NC, Mø-4HNE, and Mø-4HNE+KL groups. Cell proliferation was evaluated using CCK8 assay, while scratch test and Transwell assays were employed to measure cell migration. Additionally, tube-formation assay was conducted to assess cell tubule formation, and Western blot assay was utilized to detect the protein expression levels of Claudin 5, Occludin and ZO 1.RESULTS:The results of immunofluorescence staining showed that the fluorescence intensity of F4/80 of RAW264.7 cells in the 4HNE group was significantly enhanced compared with the control group, while that of F4/80 in the 4HNE+KL group was significantly decreased compared with the 4HNE group(all P<0.05). The CCK8 assay results revealed a significant increase in the proliferation of HUVECs in the Mø-4HNE group compared with the Mø-NC group. Conversely, the proliferation of the Mø-4HNE+KL group exhibited a significant decrease compared with that in the Mø-4HNE group(all P<0.01). The results of scratch test and Transwell assays demonstrated a significant increase in the migration of HUVECs in the Mø-4HNE group compared with the Mø-NC group, while the migration of the Mø-4HNE+KL group exhibited a significant decrease compared with the Mø-4HNE group(all P<0.01). In the tube-formation assay, it was observed that the number of tubes formed by HUVECs in the Mø-4HNE group was significantly increased compared with the Mø-NC group, while that of tubes formed in the Mø-4HNE+KL group was significantly decreased compared with the Mø-4HNE group(all P<0.01). Additionally, the Western blot results revealed a significant decrease in the relative expression levels of Claudin 5, Occludin, and ZO 1 in the Mø-4HNE group compared with the Mø-NC group. Conversely, in the Mø-4HNE+KL group, there was a significant increase in the relative expression levels of Claudin 5, Occludin, and ZO 1 compared to the Mø-4HNE group(all P<0.01).CONCLUSIONS: KL inhibits the proliferation, migration, and tube-formation of HUVECs while enhancing the tight junction by changing the activation state of macrophages in the diabetic oxidative stress environment.
