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 molecular mechanisms by which Wenyang Jiedu granules (WYJD) alleviate influenza A virus (IAV)-induced pneumonia based on single-cell transcriptome sequencing. MethodsThirty female BALB/c mice were randomly divided into a blank control group (Control), IAV group, and WYJD low-, medium-, and high-dose groups (WYJD-L, WYJD-M, WYJD-H; 2.925, 5.85, 11.7 g·kg-1, n=6). Except for the Control group, all other groups were intranasally inoculated with IAV subtype H1N1 (A/PR/8/34) to establish an infection model. Two hours after modeling, drug administration was initiated and continued for 5 consecutive days, with daily monitoring of body weight and general condition. On day 6, mice were sacrificed and samples were collected. Lung index was calculated, and histopathological examination of lung tissue was performed. Lung tissues from the Control, IAV, and WYJD-H groups were subjected to single-cell transcriptome sequencing (n=3), focusing on type I alveolar epithelial cells (AT1) to analyze changes in gene expression and signaling pathways. Western blot was used to detect the expression changes of relevant proteins to validate the single-cell sequencing results. ResultsCompared with the Control group, the IAV group exhibited significantly decreased body weight (P<0.05) and significantly increased lung index (P<0.05). Compared with the IAV group, all WYJD-treated groups exhibited significantly increased body weight (P<0.01) and significantly decreased lung index (P<0.01). Single-cell sequencing analysis revealed that WYJD inhibited overactivation of interferon and inflammatory signaling pathways in AT1 cells after IAV infection, including interferon-γ response, interferon-α response, tumor necrosis factor-α/nuclear factor-κB (TNF-α/NF-κB), and interleukin-6/Janus kinase/signal transducer and activator of transcription 3 (IL-6/JAK/STAT3) pathways. Compared with the Control group, the number of AT1 cells in the IAV group showed a decreasing trend. Compared with the IAV group, the WYJD-H group showed an increasing trend, although neither difference was statistically significant. Further analysis of AT1 cell subpopulation gene expression showed that, compared with the Control group, the IAV group exhibited increased expression of pro-apoptotic genes FAS cell surface death receptor (FAS) and cyclin-dependent kinase inhibitor 1A (CDKN1A), a significant increase in tumor protein p53 (Tp53) expression (P<0.05), and significant decreases in expression of the AT1 marker gene advanced glycosylation end-product-specific receptor (AGER) and membrane structural gene caveolin1 (CAV1) (P<0.05, P<0.01). Compared with the IAV group, the WYJD-H group showed significantly decreased expression of FAS, CDKN1A, and Tp53 (P<0.05, P<0.01), and significantly increased expression of AGER and CAV1 (P<0.05, P<0.01). Regarding interferon response-related genes, compared with the Control group, the IAV group showed increased expression of interferon-stimulated gene 15 (ISG15), interferon-induced protein with tetratricopeptide repeats 3 (IFIT3), signal transducer and activator of transcription 2 (STAT2), bone marrow stromal cell antigen 2 (BST2), and C-X-C motif chemokine ligand 10 (CXCL10), with a significant increase in 2′,5′-oligoadenylate synthetase-like protein 1 (OASL1) (P<0.05). Compared with the IAV group, the WYJD-H group showed significantly decreased expression of all the above genes, with highly significant differences for ISG15, IFIT3, STAT2, BST2, and OASL1 (P<0.01), and a significant difference for CXCL10 (P<0.05). Among inflammation-related genes, compared with the Control group, the IAV group showed significantly increased expression of intercellular adhesion molecule 1 (ICAM1), tumor necrosis factor alpha-induced protein 3 (TNFAIP3), keratin 8 (KRT8), tumor necrosis factor receptor superfamily member 1A (TNFRSF1A), and TNFRSF1B (P<0.01), and increased expression of NFKBIA, a negative regulator of NF-κB (P<0.05). Compared with the IAV group, the WYJD-H group showed significantly decreased expression of KRT8 and TNFRSF1B (P<0.05), while ICAM1, NFKBIA, TNFAIP3, and TNFRSF1A showed decreasing trends without statistical significance. Western blot validation showed that, compared with the Control group, protein expression levels of ISG15, FAS, p53, and phosphorylated p65 (p-p65) in lung tissue of the IAV group were significantly increased (P<0.05, P<0.01). Compared with the IAV group, the WYJD-H group showed significantly decreased expression of these proteins (P<0.05, P<0.01). ConclusionWYJD may alleviate viral pneumonia by targeting gene expression in AT1 cells, inhibiting overactivated interferon and inflammatory signaling pathways after IAV infection, and downregulating pro-apoptotic signaling, thereby reducing alveolar epithelial injury.

ObjectiveTo establish a mouse model of hypoxic pulmonary hypertension (HPH) through intermittent hypoxia induction, and to develop a comprehensive and reliable evaluation system for the HPH model, thereby providing experimental evidence for mechanistic studies and translational applications related to this disease. MethodsTwenty-four male specific pathogen-free (SPF) BALB/c mice were randomly divided into a control group and a model group, with 12 mice per group. Mice in the model group were placed in a hypobaric oxygen chamber control system to establish the HPH model, whereas mice in the control group received no intervention. After 28 days of modeling, a comprehensive evaluation of the pathophysiological characteristics of both groups was performed using a general condition scoring scale, echocardiography, hemodynamic measurements, blood gas analysis, hematological tests, organ coefficient determination, histopathological examination, and enzyme-linked immunosorbent assay (ELISA). In addition, correlation analyses were conducted among echocardiographic parameters, the contents of endothelin‑1 (ET‑1) and N‑terminal pro‑B‑type natriuretic peptide (NT‑proBNP) in lung tissue, and other measured indices. ResultsWith prolonged modeling duration time, body weight, water intake, and activity level of mice in the model group were significantly decreased compared with the control group (P<0.05). Echocardiography showed that, compared with the control group, the model group exhibited increased right ventricular dimensions (P<0.01), right ventricular anterior wall thickening (P<0.01), and widened main pulmonary artery diameter (P<0.01), whereas the peak systolic velocity across the pulmonary valve, tricuspid annular plane systolic excursion, and peak systolic velocity of the tricuspid annulus were significantly decreased (P<0.001); tricuspid regurgitation was observed in some model animals. Hemodynamic results revealed that right ventricular systolic pressure was elevated in the model group compared with the control group (P<0.001). Blood gas analysis showed that pH, partial pressure of oxygen, oxygen saturation, actual bicarbonate, and total carbon dioxide were all decreased in the model group compared with the control group (P<0.01). Hematological indices demonstrated that lymphocyte counts (P<0.05) and reticulocyte counts (P<0.001) were decreased in the model group compared with the control group. Compared with the control group, the organ coefficients of heart and lung in the model group were significantly increased (P<0.05 and P<0.001). Pathological examination revealed that the right ventricular hypertrophy index was significantly increased in the model group (P<0.001), with varying degrees of damage to the right ventricle, pulmonary artery, and pulmonary vessels; both the pulmonary artery wall thickness percentage and the pulmonary wall area percentage were significantly elevated (P<0.001). ELISA results showed that the levels of ET‑1 and NT‑proBNP in lung tissues were significantly increased in the model group compared with the control group (P<0.05 and P<0.001, respectively). Correlation analysis indicated that some echocardiographic parameters were highly correlated with multiple indices in the development of HPH (P<0.05). ConclusionEchocardiography can accurately assess a series of hemodynamic changes in HPH, including right ventricular structural, functional impairment, and pulmonary hypertension. Laboratory tests not only help verify whether the model has been successfully established, but also provide deeper insights into the pathogenesis of HPH, evaluate the effects of interventions, and offer scientific evidence for clinical outcomes. Pathological examination can further confirm the alterations in pulmonary vascular remodeling and increased right heart load. This multimodal analysis provides a reliable animal model and evaluation paradigm for both basic and translational research on HPH, and is of great significance for exploring disease mechanisms and developing precision therapeutic strategies.

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.

OBJECTIVE:
To compare the effects of different chest compression rates (60-140 times/min) on hemodynamic parameters, return of spontaneous circulation (ROSC), resuscitation success, and survival in a porcine model of cardiac arrest (CA) followed by cardiopulmonary resuscitation (CPR).
METHODS:
Forty healthy male domestic pigs were randomly divided into five groups based on chest compression rate: 60, 80, 100, 120, and 140 times/min (n = 8). All animals underwent standard anesthesia and tracheal intubation. A catheter was inserted via the left femoral artery into the thoracic aorta to monitor aortic pressure (AOP), and another via the right external jugular vein into the right atrium to monitor right atrial pressure (RAP). In each group, animals were implanted with a stimulating electrode via the right external jugular vein to the endocardium, and ventricular fibrillation (VF) was induced by delivering alternating current stimulation, resulting in CA. After a 1-minute, manual chest compressions were performed at the assigned rate with a compression depth of 5 cm. The first defibrillation was delivered after 2 minutes of CPR. No epinephrine or other pharmacologic agents were administered during the entire resuscitation process. From 1 minute before VF induction to 10 minutes after ROSC, dynamic monitoring of AOP, coronary perfusion pressure (CPP), and partial pressure of end-tidal carbon dioxide (PETCO2). Cortical ultrastructure was examined 24 hours post-ROSC using transmission electron microscopy.
RESULTS:
With increasing compression rates, both the total number of defibrillations and cumulative defibrillation energy significantly decreased, reaching their lowest levels in the 120 times/min group. The number of defibrillations decreased from (4.88±0.83) times in the 60 times/min group to (2.25±0.71) times in the 120 compressions/min group, and energy from (975.00±166.90)J to (450.00±141.42)J. However, both parameters increased again in the 140 times/min group [(4.75±1.04)times, (950.00±207.02)J], the differences among the groups were statistically significant (both P < 0.01). As compression frequency increased, PETCO2, pre-defibrillation AOP and CPP significantly improved, peaking in the 120 times/min group [compared with the 60 times/min group, PETCO2 (mmHg, 1 mmHg≈0.133 kPa): 18.69±1.98 vs. 8.67±1.30, AOP (mmHg): 95.13±7.06 vs. 71.00±6.41, CPP (mmHg): 14.88±6.92 vs. 8.57±3.42]. However, in the 140 times/min group, these values declined significantly again [PETCO2, AOP, and CPP were (10.59±1.40), (72.38±11.49), and (10.36±4.57) mmHg, respectively], the differences among the groups were statistically significant (all P < 0.01). The number of animals achieving ROSC, successful resuscitation, and 24-hour survival increased with higher compression rates, reaching a peak in the 120 times/min group (compared with the 60 times/min group, ROSC: 7 vs. 2, successful resuscitation: 7 vs. 2, 24-hour survival: 7 vs.1), then decreased again in the 140 times/min group (the animals that ROSC, successfully recovered and survived for 24 hours were 3, 3, and 2, respectively). Transmission electron microscopy revealed that in the 60, 80, and 140 times/min groups, nuclear membranes in cerebral tissue were irregular and incomplete, nucleoli were indistinct, and mitochondria were swollen with reduced cristae and abnormal morphology. In contrast, the 100 times/min and 120 times/min groups exhibited significantly attenuated ultrastructural damage.
CONCLUSIONS
Among the tested chest compression rates of 60-140 times/min, a chest compressions frequency of 120 times/min is the most favorable hemodynamic profile and outcomes during CPR in a porcine CA model. However, due to the wide spacing between groups, further investigation is needed to determine the optimal compression rate range more precisely.

Objective To investigate the relationship between the levels of soluble FMS-like tyrosine ki-nase-1(sFlt-1),monocyte chemoatgulant protein-1(MCP-1),and soluble lectin-like oxidized low-density lipo-protein receptor 1(sLOX-1)in the serum of patients with coronary heart disease and the disease state and prognosis.Methods A total of 126 patients with coronary heart disease treated in Zhongshan Hospital,Dalian University from May 2022 to May 2024 were selected as study objects.The patients were divided into good prognosis group(n=78)and poor prognosis group(n=48)according to prognostic results.The serum sFlt-1,MCP-1 and sLOX-1 levels were detected by enzyme-linked immunosorbent assay.The degree of coronary artery stenosis in patients was measured by coronary angiography,as indicated by the Gensini score.Spearman correlation analysis was used to analyze the correlation between Gensini score and serum sFlt-1,MCP-1 and sLOX-1 levels.Multivariate Logistic regression was used to analyze the factors affecting the prognosis of pa-tients with coronary heart disease.The predictive efficacy of serum sFlt-1,MCP-1 and sLOX-1 levels for the prognosis of patients with coronary heart disease was evaluated by receiver operating characteristic(ROC)curve.Results The age in the poor prognosis group was older than that in the good prognosis group(P<0.05),Gensini score was higher than that in the good prognosis group(P<0.05).Compared with the poor prognosis group,the serum sFlt-1,MCP-1 and sLOX-1 levels in the good prognosis group were lower(P<0.05).Gensini score was positively correlated with the serum sFlt-1,MCP-1 and sLOX-1 levels.Multivariate Logistic regression analysis showed that old age,high Gensini score,high sFlt-1 level,high MCP-1 level and high sLOX-1 level were all risk factors effecting the prognosis of patients with coronary heart disease(P<0.05).ROC curve analysis showed that the areas under the curve(AUC)of serum sFlt-1,MCP-1,and sLOX-1 for predicting the prognosis of coronary heart disease patients were 0.787(95%CI:0.703-0.870),0.815(95%CI:0.741-0.890)and 0.795(95%CI:0.715-0.876),respectively.The AUC for predicting the prognosis of coronary heart disease patients using a combination of three was 0.923(95%CI:0.876-0.970).Conclusion The serum levels of sFlt-1,MCP-1 and sLOX-1 in patients with coronary heart disease are signifi-cantly increased,and are positively correlated with the degree of coronary artery stenosis.The levels of sFlt-1,MCP-1 and sLOX-1 in serum have a certain predictive effect on the prognosis of patients with coronary heart disease.
