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.

OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets, followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established , and the zebrafish were treated with L. ruthenicum Murr. extract (LRME) at concentrations of 0.1, 0.2 and 0.4 mg/mL, respectively; 24 h later, behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 (IL-6), IL-1β, IL-10, tumor necrosis factor-α (TNF-α)], oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), catalase (CAT)], and neurotransmitters [5- hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), glutamic acid (Glu), dopamine (DA), and norepinephrine (NE)] were measured. The protein expression levels of protein kinase B1 (AKT1), phosphorylated AKT1 (p-AKT1), epidermal growth factor receptor (EGFR), B-cell lymphoma 2 (Bcl-2), sarcoma proto-oncogene,non-receptor tyrosine kinase (SRC), and heat shock protein 90α family class A member 1 (HSP90AA1) in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these, apigenin, naringenin and others were recognized as core active compounds, while AKT1, EGFR and others served as key targets; EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-, medium-, and high-dose groups were 54.60%, 69.03% and 77.97%, 开发。E-mail:hjp_yft@163.com respectively, while the inhibition ratios of locomotor distance were 0.57, 0.83 and 0.95, respectively. Compared with the model group, the number of resting counts, resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups (P<0.05). Neuronal damage in the brain was alleviated. Additionally, the levels of IL-6, IL-1β, TNF-α, MDA, Glu, DA and NE, as well as the protein expression levels of AKT1, p-AKT1, EGFR, SRC and HSP90AA1, were markedly reduced (P<0.05), while the levels of IL-10, SOD, GSH-Px, CAT, 5-HT and GABA, as well as Bcl-2 protein expression, were significantly elevated (P<0.05). CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects, and its specific mechanism may be related to the regulation of inflammatory responses, oxidative stress, neurotransmitter balance, and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

ObjectiveTo investigate the effect of Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma on ferroptosis in the rat model of myocardial infarction and further elucidate its role in myocardial remodeling. MethodsThe rat model of myocardial infarction was established by ligation of the left anterior descending coronary artery. The 50 successfully modeled rats were randomly divided into model group, ferroptosis inhibitor group (2 mg·kg-1), enalapril group (2.1 mg·kg-1), and low- and high-dose (4 g·kg-1 and 8 g·kg-1, respectively) Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma, with 10 rats in each group. The rat model of myocardial infarction was established by ligation of the left anterior descending coronary artery. After 4 weeks of treatment, echocardiography was used to assess the cardiac structure and function. Hematoxylin-eosin (HE) staining and Masson staining were employed to observe pathological morphology and fibrosis of the myocardial tissue. Serum levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), transforming growth factor-β (TGF-β), and myosin heavy chain-β (MHC-β) were measured by enzyme-linked immunosorbent assay (ELISA). Prussian blue staining was performed to detect myocardial iron deposition. The myocardial mitochondrial structure was observed by transmission electron microscopy. Levels of malondialdehyde (MDA) and glutathione (GSH) in the myocardial tissue were determined by lipid peroxidation assay kits. Immunofluorescence assay was conducted to observe the fluorescence intensity of nuclear factor E2-related factor 2 (Nrf2) in the myocardial tissue. Western blot analysis was performed to evaluate the expression levels of proteins in the Nrf2/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) pathway. ResultsCompared with the sham group, the model group showed increased left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), and serum levels of NT-proBNP, TGF-β, and MHC-β (P<0.01), decreased left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) (P<0.01), disarrangement of myocardial cells, inflammatory cell infiltration, severe myocardial fibrosis, increased myocardial iron deposition, and irregular mitochondrial morphology with vacuolation. Furthermore, the modeling led to increased MDA (P<0.01), decreased GSH (P<0.01), diminished Nrf2 fluorescence intensity in the myocardial tissue, and downregulated expression levels of Nrf2, SLC7A11, and GPX4 (P<0.01). Compared with the model group, Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma reduced the LVEDD, LVESD, and serum levels of NT-proBNP, TGF-β, and MHC-β (P<0.05, P<0.01), increased the LVEF and LVFS (P<0.05, P<0.01), alleviated pathological changes such as myocardial cell disarrangement, inflammatory cell infiltration, myocardial fibrosis, and iron deposition, lowered the level of MDA (P<0.05, P<0.01), raised the level of GSH (P<0.05, P<0.01), improved the mitochondrial morphology and reduced vacuolation in the myocardial tissue, enhanced Nrf2 fluorescence intensity, and upregulated the expression levels of Nrf2, SLC7A11, and GPX4 (P<0.05, P<0.01) in the rat model of myocardial infarction. ConclusionGardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma alleviates pathological damage and myocardial remodeling in the rat model of myocardial infarction by inhibiting ferroptosis, the mechanism of which is related to the activation of Nrf2/SLC7A11/GPX4 signaling pathway.

Objective:To investigate the combined application of cytology, cell block histology and immunohistochemistry to improve the diagnostic accuracy of solid pancreatic lesions in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) samples.Methods:The pathological data of EUS-FNA in 311 cases of solid pancreatic lesions submitted to the Second Hospital of Hebei Medical University, Shijiazhuang, China from May 2019 to September 2023 were retrospectively analyzed. The cases included pancreatic ductal adenocarcinoma (PDAC, 172 cases), solid pseudopapillary neoplasm (SPN, 12 cases), neuroendocrine tumors (PNET, 14 cases) and chronic pancreatitis (113 cases). The cytological features of smears, the histology of cell block sections and the diagnostic markers in PDAC, SPN and PNET were analyzed. The diagnostic accuracies of cytology, cell block histology/immunohistochemistry and combination of the two methods for classifying these pancreatic solid lesions were evaluated.Results:Irregular arrangement of atypical (cancer) cells, anisonucleosis and nuclear atypia were the typical cytological features of PDAC, while presence of pseudopapillae with a myxoid/hyalinized fibrovascular core and low adhesion/salt-and-pepper chromatin were diagnostic features of SPN and NET, respectively. Immunohistochemical results showed that CK7 and CK19 were the most sensitive markers of pancreatic ductal epithelia, and the diffuse strong expression of S-100P (102/111, 91.9%) and aberrant expression of p53 (80/111, 72.1%) were important immunophenotypic markers of PDAC. Various degrees of CDX2 expression could be found in 66.4% PDAC. The expression of CD10, PR, vimentin, CD99 and cyclinD1 and the aberrant expression of β-catenin were the immunophenotypic features of SPN, while the expression of CgA, Syn and CD56 were indispensable immunemarkers for the diagnosis of PNET. Overall, cytology had higher sensitivity than cell block histology (93.9% versus 82.8%) and lower specificity (92.9% versus 99.1%), while the combination of the two methods significantly improved the sensitivity to 96.9% in solid pancreatic lesions. The combination of cytology and cell block histology could significantly improve the diagnostic efficacy of EUS-FNA in PDAC.Conclusions:Integrated diagnosis based on cytology (including rapid on-site evaluation), cell block histology and immunohistochemical findings could significantly improve the diagnostic yield of EUS-FNA in classifying solid pancreatic lesions.

Objective:To investigate the association between different sleep patterns and anxiety and depression in hemodialysis patients, thereby providing a reference for improving their psychological and sleep conditions.Methods:This study was a cross-sectional survey.A convenience sampling method was used to select patients undergoing regular dialysis at a hemodialysis centre in the Sixth People's Hospital of Huizhou from May 2023 to May 2024. Sleep quality, anxiety and depression symptoms were assessed using the Pittsburgh Sleep Quality Index (PSQI), Self-rating Anxiety Scale for (SAS) and Self-rating Depression Scale (SDS). Potential profiles were analyzed using Mplus 8.3 and mixed-effects Logistic regression was used to explore the association between sleep pattern category and anxiety-depression.Results:A total of 264 valid questionnaires were returned, of which 142 were males and 122 were females, aged (56.61 ± 12.69) years old. The sleep patterns of hemodialysis patients were divided into three potential categories:patients with overall better sleep quality31.4%(83/264), patients with poor sleep using hypnotic medication12.9%(34/264), and patients with poor sleep without hypnotic medication 55.7%(147/264). Significant differences were found in age, education, anxiety and depression across different sleep categories ( χ2 values were 9.75-25.72, all P<0.05). Compared with the group with overall better sleep quality, the risk of anxiety was higher in the group with sleep difficulties without hypnotic medication ( OR=5.409, P<0.05), and the risk of anxiety and depression ( OR=5.010, 6.488, both P<0.05) was higher in the group with sleep disorders using hypnotic medication. Compared with patients with poor sleep without hypnotic medication, patients with poor sleep using hypnotic medication had a higher risk of depression ( OR=6.501, P<0.05). Conclusions:There are three potential categories of sleep patterns in hemodialysis patients and significant correlations between them and anxiety and depression, and precise screening and individualized interventions need to be implemented in the clinic to improve patients' quality of life.
