Objective: To explore the effects of different types of acute exercise on the working memory of sedentary college students，so as to provide a basis for exercise intervention. Methods: From April 15 to May 30, 2023, a total of 42 sedentary college students were recruited from one university in Beijing. Using a single blind, completely randomized experimental design, participants were randomly assigned to an open skill exercise group, a closed skill exercise group, or a control group, with 14 participants in each group. The open skill exercise group engaged in 30 minutes of badminton, the closed skill exercise group performed 30 minutes of running, and the control group remained seated for 30 minutes. All participants completed a 2-back working memory task and had their electroencephalogram (EEG) data recorded before and after the intervention. Results: The accuracy rates of the open skill exercise group, closed skill exercise group, and control group (0.90±0.06, 0.94±0.05; 0.88±0.05, 0.94±0.05; 0.85±0.10, 0.90±0.06) showed a significant main effect of time ( F=37.14, P <0.01). Reaction times [(923.65±145.08, 711.56± 140.93 ; 909.59±180.28, 807.85±169.66; 917.05±166.35, 871.86±186.07)ms] showed both a significant main effect of time and a significant interaction between group and time ( F=70.55, 11.83, P <0.01). Repeated measures ANOVA revealed that all three groups improved in accuracy and reaction time compared to pre test values, with no significant difference in accuracy between groups. However, the reaction time of the open skill exercise group was significantly faster than that of the control group ( P <0.05), while there was no significant difference between the closed skill exercise group and the control group ( P >0.05). For EEG data, the P2 amplitude showed a significant main effect of time and a significant interaction between groups and time ( F=10.60, 7.66, P < 0.01 ), with the open skill exercise group exhibiting a higher P2 amplitude than the control group ( P <0.05), while the closed skill exercise group showed no significant difference compared to the control group ( P >0.05). The N2 amplitude showed a significant main effect of time ( F=5.94, P <0.05). The P3 amplitude showed significant main effects of time and electrode position, as well as a significant interaction between groups and time ( F=23.16, 4.53, 5.85, P <0.05), with both exercise groups exhibiting higher P3 amplitudes than the control group ( P <0.05), but no significant difference between the two exercise groups ( P >0.05). Conclusion Open skill exercise is more effective than closed skill exercise in improving the working memory of sedentary college students.

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.

ObjectiveTo explore the mechanism of Renshen Baidusan in repairing intestinal mucosa in ulcerative colitis （UC） by regulating autophagy to scavenge peroxides. MethodThe mouse model of UC was induced by free drinking of 3.0% dextran sulphate sodium （DSS） solution. Sixty male C57BL/6J mice were randomized into normal， model， mesalazine （0.3 g·kg^-1）， and high-， medium-， and low-dose （12.35， 8.22， 4.11 g·kg^-1， respectively） Renshen Baidusan groups （n=10）. The mice were administrated with corresponding drugs by gavage for 7 consecutive days. The colon tissue was stained with hematoxylin-eosin （HE） to reveal the pathological changes， and Alcian blue-Periodic acid Scheff （PAS/AB） staining was employed to observe the goblet cell changes. The fluorescence expression of reactive oxygen species （ROS） in the colon tissue was detected by the immunofluorescence assay. The activity of superoxide dismutase （SOD） and the content of malondialdehyde （MDA） were measured by the biochemical methods. Western blot was employed to determine the expression levels of proliferating cell nuclear antigen （PCNA）， microtubule-associated protein 1 light chain 3 （LC3）， leucine-rich repeat-containing G protein-coupled receptor 5 （LGR5）， and p62. ResultDestroyed mucosal epithelial structure， intestinal gland destruction， loss of goblet cells， and massive infiltration of inflammatory cells appeared in the model group. Compared with the normal group， the model group showed increased tissue damage injury （TDI） score of the colon tissue， decreased SOD activity and LC3Ⅱ/Ⅰ， PCNA value， and elevated levels of p62， MDA， ROS， and LGR5 （P<0.05）. Compared with the model group， different doses of Renshen Baidusan decreased the TDI score， promoted the generation of new goblet cells， elevated the levels of PCNA， LGR5， SOD， and LC3Ⅱ/Ⅰ， and lowered the levels of p62， MDA， and ROS （P<0.05）. Moreover， the low dose group showed the best performance （P<0.05）. ConclusionRenshen Baidusan can promote intestinal epithelial repair by activating intestinal autophagy， alleviating oxidative stress， and promoting intestinal stem cell proliferation and differentiation.

ObjectiveTo explore the mechanisms of internal treatment （Renshen Baidusan）， external treatment （Yurui Enema）， and combination of the two methods in treating intestinal mucosal injury in the rat model of ulcerative colitis （UC） from the changes of phosphatidylinositol-3 kinase （PI3K）/protein kinase B （Akt）/nuclear factor-κB （NF-κB） pathway. MethodFifty SPF-grade SD rats were randomized into blank， model， Renshen Baidusan （15.6 g·kg^-1）， Yurui Enema （25 g·kg^-1）， and combined treatment （15.6 g·kg^-1 Renshen Baidusan + 25 g·kg^-1 Yurui Enema） groups （n=10）. The rat model of UC was established in other groups except the blank group by 2，4， 6-trinitrosulfonic acid （TNBS）/ethanol. The rats were administered with corresponding drugs once a day for 14 consecutive days since the 8th day after modeling. The histopathological changes of colon were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor （TNF）-α， interferon （IFN）-γ， interleukin （IL）-4， and IL-10 in the colon tissue. The apoptosis of colon epithelial cells was detected by terminal deoxynucleotidyl transferase-mediated nick end labeling （TUNEL）. The location and expression of B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， TNF-α， and IL-6 in the colon tissue were examined by immunohistochemistry. Real-time quantitative fluorescence polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the mRNA and protein levels， respectively， of the proteins in the PI3K/Akt/NF-κB pathway in the colon tissue. ResultIn the model group， HE staining showed a large number of inflammatory cell infiltration in the mucosa and submucosa. Compared with the blank group， the model group showed elevated levels of TNF-α and IFN-γ and lowered levels of IL-4 and IL-10 in the colon tissue， increased apoptosis rate of colon epithelial cells， increased positive expression of Bax， TNF-α， and IL-6， and decreased positive expression of Bcl-2 （P<0.05）. Moreover， the model group showed up-regulated mRNA levels of PI3K， Akt， and NF-κB and protein levels of PI3K， p-PI3K， Akt， p-Akt， p65， p-p65， Bax， and cleaved Caspase-3， increased Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios， and down-regulated protein levels of NF-κB suppressor protein α（IκBα）， Bcl-2， and Caspase-3 in the colon tissue （P<0.05）. Compared with the model group， the internal treatment， the external treatment， and the combination （referred to as the three groups） alleviated the colonic mucosal injury， lowered the levels of TNF-α and IFN-γ and elevated the levels of IL-4 and IL-10 in the colon tissue， decreased the apoptosis rate of colon cells， inhibited the positive expression of Bax， TNF-α， and IL-6， and promoted the positive expression of Bcl-2 （P<0.05）. Furthermore， the combination group down-regulated the mRNA level of PI3K （P<0.05）. The three groups down-regulated the mRNA levels of Akt and NF-κB and the protein levels of p-PI3K， Akt， p-Akt， p65， p-p65， Bax， and cleaved Caspase-3 in the colon tissue， decreased the Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios， and up-regulated the protein levels of IκBα， Bcl-2， and Caspase-3 （P<0.05）. ConclusionRenshen Baidusan， Yurui Enema， and their combination may inhibit the activation of PI3K/Akt/NF-κB signaling pathway and regulate the expression of genes and proteins related to this pathway to achieve anti-inflammatory and anti-apoptotic effects， thus restoring the intestinal mucosal barrier function of UC rats.

ObjectiveTo study the mechanism of Renshen Baidusan in regulating adenylate-activated protein kinase （AMPK）/Unc-51-like kinase 1 （ULK1） autophagy pathway to inhibit mucosal barrier damage in the mouse model of ulcerative colitis （UC）. MethodSixty SD rats were randomized into normal， model， sulfasalazine enteric-coated tablets （0.312 5 g·kg^-1， western medicine）， and high-， medium-， and low-dose （31.2， 15.6， 7.8 g·kg^-1， respectively） Renshen Baidusan groups. The UC model was induced by 2，4，6-trinitrobenzenesulfonic acid （TNBS）/50% ethanol. The drugs were administrated by gavage for 2 weeks， and then the histopathological changes of the colon were examined. Real-time quantitative polymerase chain reaction was conducted to measure the mRNA level of AMP-activated protein kinase subunit alpha （AMPKα）. Western blot was employed to determine the protein levels of closure protein （Occludin）， compact linking protein-2 （Claudin-2）， autophagy marker p62， microtubule-associated protein 1 light chain 3B （LC3B）， phosphorylated AMPK （p-AMPK）， and phosphorylated ULK1 （p-ULK1）. ResultCompared with the normal group， the model group showed increased colon injury score （P<0.05）， down-regulated mRNA level of AMPKα （P<0.05） and protein levels of p-AMPK， p-ULK1， and Occludin， decreased LC3Ⅱ/Ⅰ ratio （P<0.05）， and up-regulated protein levels of p62 and Claudin-2 （P<0.05）. Compared with the model group， all the doses of Renshen Baidusan lowered the colon injury score， up-regulated the mRNA level of AMPKα and the protein levels of p-AMPK， p-ULK1， and Occluding， increased LC3Ⅱ/Ⅰ ratio， and down-regulated the protein levels of p62 and Claudin-2. Moreover， the medium-dose group showed a significant intervention effect （P<0.05）. ConclusionRenshen Baidusan can protect the intestinal mucosal barrier from damage， and the medium dose showed the best efficacy. It may activate the AMPK/ULK1 pathway to accelerate the transformation of LC3Ⅰ to LC3Ⅱ and promote the degradation of p62， so as to improve the function of Occludin and Claudin-2 and repair the mechanical damage of the intestinal barrier.
