OBJECTIVE To investigate the effects of total flavonoids from Carthamus tinctorius L. (TFCTL) on hepatic stellate cell (HSC) activation based on the microRNA (miRNA)-204/NUAK family SNF1-like kinase 1 (NUAK1)/Hippo signaling axis, thereby elucidating the potential mechanism underlying their antifibrotic effects. METHODS The HSC-T6 cells were divided into control group, model group, TFCTL low-concentration group (20 μg/mL), TFCTL medium-concentration group (40 μg/mL), and TFCTL high-concentration group (60 μg/mL). Except for control group, the remaining groups were treated with 5 ng/mL of transforming growth factor-β to induce the activation of hepatic stellate cells, followed by the addition of corresponding drug solutions/culture medium and incubation for 24 hours. Cell apoptosis was assessed, the expression levels of α-smooth muscle actin (α-SMA), type Ⅰ collagen (Collagen Ⅰ) and proteins associated with the Hippo/Yes-associated protein (YAP) pathway [YAP, large tumor suppressor kinase 1 (LATS1), and mammalian STE20-like kinase 1 (MST1)] were detected. Additionally, cell transfection was used to investigate the activity of the miRNA-204/NUAK1/Hippo signaling axis at both the genetic and protein levels. RESULTS After intervention with TFCTL, the apoptosis rate of HSC-T6 cells and the protein expressions of MST1 (except for the TFCTL high-concentration group) and LATS1 were significantly increased (P<0.05), while the protein expressions of α-SMA, CollagenⅠ, and YAP (except for the TFCTL medium-concentration group) were significantly decreased (P<0.05). Further results from cell transfection experiments revealed that after transfection with miRNA-204 mimics, the mRNA it’s protein expressions of α-SMA, CollagenⅠ, NUAK1, and YAP in HSC-T6 cells were significantly decreased (P<0.05), while the mRNA and protein expressions of LATS1 and the mRNA expression of MST1 were significantly increased (P<0.05). Conversely, the results were opposite following transfection with miRNA-204 inhibitors. CONCLUSIONS TFCTL can exert anti-hepatic fibrosis effects by up-regulating the expression of miRNA-204, thereby down- regulating the expressions of NUAK1, inactivating the Hippo/YAP pathway, which in turn suppresses the activation of HSC and promotes their apoptosis.

BackgroundIn recent years, the incidence of depression among adolescents has been increasing steadily, posing a serious threat to their physical and mental health and even leading to severe consequences such as self-harm and suicide. At the same time, the detection rate of subclinical depression symptoms among adolescents is even higher. Although these symptoms do not meet the clinical diagnostic criteria, they have significantly affected their quality of life, and their persistence over time may further develop into depression. Therefore, in-depth exploration of adolescent depression symptoms and the predictive factors holds significant practical significance and research value. However, up to now, no large-scale investigation and research on depression symptoms among children and adolescents has been conducted in Inner Mongolia Autonomous Region. ObjectiveTo understand the prevalence of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region, in order to provide references for formulating scientific and effective prevention strategies and intervention measures. MethodsBy using the cluster stratified random sampling method, 6 281 students from the third grade of primary school to the second grade of high school in 12 leagues and cities of Inner Mongolia Autonomous Region were selected in March 2024. A self-designed questionnaire and the Self-rating Depression Scale (SDS) were used for on-site investigation. ResultsA total of 6 058 (96.45%) children and adolescents completed the valid questionnaire survey, and 2 728 cases (45.03%) were found to have depressive symptoms. There were statistically significant differences in the detection rates of depressive symptoms among children and adolescents of different genders, ages, whether they were only children, different family types, family monthly income, parents' educational levels, and whether the mother was employed (χ2=33.769, 40.618, 48.593, 29.972, 142.648, 195.999, 168.190, 5.445, P<0.05 or 0.01).The results of the Logistic regression analysis showed that for children and adolescents, being female, aged between 12 and 16, over 16 years old, not being an only child, living in a reconstituted family, having a monthly family income of less than 5 000 yuan, and having parents with an education level of primary school or below were predictors of depressive symptoms (OR=1.241, 1.427, 1.273, 1.177, 1.549, 1.278, 1.462, 1.417, 1.514, 1.929, 1.660, 1.528, P<0.05 or 0.01). ConclusionThe detection rate of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Factors that may predict depressive symptoms in children and adolescents include female gender, ages between 12 and 16, ages over 16 years old, non-only children, families with a restructured structure, monthly family income of less than 5 000 yuan, and parents with an education level of primary school or below.

ObjectiveTo investigate the mechanism of Naoxintong capsules on ischemia-reperfusion (I/R) injury in rats based on the changes of pericytes mediated by Ras homolog family member A (RHOA)/Rho-associated coiled-coil containing protein kinase 1 (ROCK1) pathway. MethodsNinety rats (15 rats for each group) were randomly divided into a sham operation group, a model group, a positive control group receiving Ginkgo biloba extract (21.6 mg·kg-1), and groups receiving Naoxintong capsules at low, medium, and high doses of 55, 110, and 220 mg·kg-1 (NXT-L, NXT-M, and NXT-H groups), respectively. Except for those in the sham operation group, all rats were subjected to transient middle cerebral artery occlusion (tMCAO) to establish the experiment model. Nerve function was assessed using a neurological function score. Cerebral blood flow was detected using a laser speckle contrast imager, and the cerebral infarction rate was calculated using 2,3,5-Triphenyl tetrazolium chloride (TTC) staining. Pathological changes were observed by hematoxylin-eosin (HE) staining and Nissl staining, while pericyte morphology was observed via transmission electron microscopy. Blood-brain barrier destruction was observed by Evans blue staining. Albumin and ischemia-modified albumin levels were measured using assay kits. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were used to detect the mRNA and protein expression levels of RHOA, ROCK1, platelet-derived growth factor receptor β (PDGFRB), α-smooth muscle actin (α-SMA), tight junction protein (ZO-1), matrix metalloproteinase-2 (MMP-2), and matrix metalloproteinase-9 (MMP-9). ResultsCompared with the sham operation group, the model group exhibited decreased neurological function scores, higher percentage reduction in blood flow, and increased cerebral infarction rates (P<0.01). Additionally, cortical neuronal nucleus shrinkage, edema, a decreased number of Nissl bodies, reduced pericyte area, elevated albumin content in the cortex (P<0.05), and increased ischemic modified albumin levels (P<0.01) were observed. The mRNA and protein expression levels of RHOA, ROCK1, PDGFRB, α-SMA, MMP-2, and MMP-9 were increased (P<0.01), while those of ZO-1 were decreased. Compared with the model group, all treatment groups showed improved neurological function scores, lower percentage reduction in blood flow, reduced cerebral infarction rates (P<0.01), alleviated cortical histological changes, increased number of Nissl bodies, expanded pericyte area, decreased albumin content in the cortex, and reduced ischemia-modified albumin levels (P<0.01). The mRNA and protein expression levels of RHOA, ROCK1, PDGFRB, α-SMA, MMP-2, and MMP-9 were decreased (P<0.01), while those of ZO-1 were increased. Among the treatment groups, the NXT-M group showed the most pronounced improvement in cerebral I/R injury. ConclusionNaoxintong capsules can restore cerebral blood supply, reduce microcirculation disturbance, and protect blood-brain barrier in rats with I/R injury. Its mechanism of action may be related to the inhibition of the RHOA/ROCK1 signaling pathway and reduced pericyte contraction.

Atherosclerosis, a chronic inflammatory disease, is markedly influenced by both immune and inflammatory reactions throughout its progression. Dendritic cells, as pivotal antigen-presenting entities, play a crucial role in the initiation of immune responses and the preservation of immunological homeostasis. Accumulating data indicates that dendritic cells are present in healthy arteries and accumulate significantly in atherosclerotic plaques. Novel immunotherapeutic approaches and vaccination protocols have yielded substantial clinical advancements in managing chronic inflammatory diseases, with dendritic cell-centric modalities emerging for atherosclerotic management. In this review, we delineate the essential functions and underlying mechanisms of dendritic cells and their subsets in the modulation of atherosclerotic inflammation and immune responses. We underscore the immense promise of dendritic cell-based immunotherapeutic strategies, including vaccines and innovative combinations with nanotechnological drug delivery platforms for atherosclerosis treatment. We also discuss the challenges associated with dendritic cell immunotherapy and provide perspectives on the future direction of this field.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective:To investigate the impact and potential mechanisms of Sorbin and SH3 domain-containing protein 2 (Sorbs2) on ventricular arrhythmias in mice.Methods:In the animal experiments, mating was performed using six 8-week-old Sorbs2 +/- mice (3 males and 3 females) weighing 20-22 g. Wild-type (Sorbs2 +/+, n=8) and homozygous (Sorbs2 -/-, n=6) offspring were selected as experimental subjects through genotyping. Echocardiography was performed at 16 weeks of age to record cardiac function parameters in both groups. Resting-state and caffeine-dobutamine-induced electrocardiograms were also conducted. Real-time quantitative reverse transcription polymerase chain reaction was used to detect Sorbs2 messenger RNA expression in the heart, liver, spleen, lung, kidney, brain, small intestine, and skeletal muscle tissues of wild-type mice. Western blotting was employed to measure the protein expression levels of Sorbs2 and voltage-dependent sodium channel alpha subunit 1.5 (Na v1.5) in myocardial tissues from both groups. In the cell experiments, H9C2 cells were transfected with Sorbs2 small interfering RNA as the si-Sorbs2 group, with a corresponding si-negative control group established. Western blot was performed to detect the protein expression levels of Sorbs2 and Na v1.5 in both groups. Results:Sorbs2 was abundantly expressed in cardiac tissue. Compared with wild-type mice, homozygous mice exhibited larger left ventricular end-systolic diameter, along with lower left ventricular ejection fraction and fractional shortening ( P all<0.05). Resting-state electrocardiograms revealed no spontaneous arrhythmias in either group; however, homozygous mice showed shorter RR intervals but longer QRS and QTc intervals versus wild-type mice ( P all<0.05). Following caffeine and dobutamine induction, homozygous mice demonstrated a higher incidence of ventricular arrhythmias, longer arrhythmia duration, and higher ventricular arrhythmia scores than wild-type mice ( P all<0.05). Western blot analysis revealed that Na v1.5 protein expression was markedly lower in myocardial tissues of homozygous mice compared to wild-type mice. Similarly, si-Sorbs2-transfected H9C2 cells exhibited lower Na v1.5 protein levels compared to the si-negative control group ( P<0.05). Conclusion:Sorbs2 plays a critical role in maintaining normal cardiac electrophysiological function. Deficiency of Sorbs2 may lead to impaired cardiac function and increased susceptibility to ventricular arrhythmias in mice, which could be associated with reduced expression of Na v1.5 protein.
