OBJECTIVE: This study aims to elucidate the therapeutic potential of osthole for the treatment of atopic dermatitis (AD), focusing on its ability to alleviate chronic pruritus (CP) and the underlying molecular mechanisms. METHODS: In this study, we investigated the anti-inflammatory effects of osthole in both a 2,4-dichloronitrobenzene (DNCB)-induced AD mouse model and tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) stimulated huma immortalized epidermal (HaCaT) cells. The anti-itch effect of osthole was specifically assessed in the AD mouse model. Using methods such as hematoxylin and eosin (HE) staining, enzyme-linked immunosorbent assay (ELISA), western blot (WB), quantitative real-time PCR (qRT-PCR), and immunofluorescence staining. RESULTS: Osthole improved skin damage and clinical dermatitis scores, reduced scratching bouts, and decreased epidermal thickness AD-like mice. It also reduced the levels of interleukin (IL)-31 and IL-31 receptor A (IL-31 RA) in both skin tissues and HaCaT cells. Furthermore, Osthole suppressed the protein expression levels of phosphor-p65 (p-p65) and phosphor-inhibitor of nuclear factor kappa-Bα (p-IκBα). Meanwhile, it increased the protein expression levels of peroxisome proliferator-activated receptor α (PPARα) and PPARγ in HaCaT cells. CONCLUSION These findings indicated that osthole effectively inhibited CP in AD by activating PPARα, PPARγ, repressing the NF-κB signaling pathway, as well as the expression of IL-31 and IL-31 RA.

Objective To explore the effect and mechanism of quercetin on osteogenic differentiation of bone marrow mesenchymal stem cells(BMSCs).Methods BMSCs were divided into a blank control group(Control)and quercetin(Quercetin)low-dose group(4.8 mL/kg),medium-dose group(9.6 mL/kg),and high-dose group(19.2 mL/kg)intervened with drug-containing serum,while the positive control group was treated with osteogenic differentiation medium,respectively.The cell cycle was analysed by flow cytometry,cell proliferation was detected by MTT assay,cell activity was determined by Alkaline phosphatase(ALP)assay kit,and calcified nodule formation was observed by alizarin red staining.The expression of β-catenin and the key factors of osteogenic differentiation,runt-related transcription factor 2(RUNX2)and osteocalcin(OCN),were detected by qPCR and Western blot,respectively.Results Compared with the control group,quercetin-containing serum significantly promoted the proliferation of BMSCs(P=0.000205,P=0.000063)and enhanced the formation of calcium nodules,and increased osteogenic and ALP activity after osteogenic differentiation.The results of qPCR and Western blot showed that the quercetin group significantly up-regulated the mRNA and protein expression of β-catenin(P<0.0001),RUNX2(P<0.0001)and OCN(P<0.0001)during osteogenic differentiation.Conclusion Quercetin can effectively promote the osteogenic differentiation of BMSCs,and its mechanism is achieved by activating the Wnt/β-catenin signaling pathway and up-regulating the expression of the osteogenesis-related transcription factor RUNX2.

Pregnancy with chronic kidney disease (CKD), particularly in stages 4-5, carries high risks of adverse outcomes including maternal renal failure, preeclampsia/eclampsia, fetal growth restriction, and preterm birth. This report described a 26-year-old woman with congenital solitary kidney, polycystic ovaries, and uterine septum due to PAX2 gene variant, complicated by CKD stage 4. Through multidisciplinary team precision management and individualized treatment strategies, including timely initiation of dialysis, the patient successfully maintained pregnancy until 34 +1 weeks and delivered a female infant via cesarean section. This case summarizes key management experiences for end-stage renal disease in pregnancy, highlighting early risk assessment, precise nutritional management, hemodialysis protocol optimization, and the crucial role of multidisciplinary collaboration, providing valuable references for managing CKD-complicated pregnancies.

Objective To explore the mechanism of Jiawei Jisheng Shenqi Decoction in improving the hypoxic microenvironment and antagonizing liver cirrhosis.Methods In vivo experiments were conducted using a rat model of carbon tetrachloride(CCL4)-induced liver cirrhosis.Rats were divided into normal,model,colchicine,JWJSSQ low-dose,JWJSSQ medium-dose,and JWJSSQ high-dose group.Pathological changes in liver tissues in each group were examined by hematoxylin and eosin(HE)and Masson staining,changes in serum liver function were detected using test kits,levels of hyaluronic acid(HA),laminin(LN),procollagen Ⅲ(PC Ⅲ),and collagen typeⅣ(COL4)were detected by enzyme-linked immunosorbent assay(ELISA),and protein expression levels of hypoxia-inducible factor-1α(HIF-1α),Notch1,Jagged1,and α-smooth muscle actin(α-SMA)were detected by Western blot.In vitro experiments were conducted in HSC-T6 cells,and the optimal concentration of CoCl2(100 μ mol/L,200μmol/L,400 μmol/L,600 μmol/L and 800 μmol/L)in the cultured cells and the optimal concentration of drug-containing serum(5％,10％,15％,20％)were determined by Cell Counting Kit-8(CCK-8)assay.The migration ability of cells in each group was detected by scratch testing,and changes in the apoptosis rates were determined by flow cytometry.Protein expression levels of HIF-1α,Notch1,Jagged1,α-SMA,matrix metallopeptidase 9(MMP9),and tissue inhibitor of metalloproteinases 1(TIMP-1)were detected by Western blot.Results In the in vivo experiments,liver swelling,inflammatory cell infiltration,collagen deposition,and the appearance of pseudolobules were significantly increased in the model group compared with those in the normal group.Serum levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),HA,LN,PCⅢ,and COL4 were significantly increased and albumin(ALB)was significantly decreased in the model group,while liver levels of HIF-1α,Notch1,Jagged1,and α-SMA proteins were significantly increased(P＜0.01).Liver swelling,inflammatory cell infiltration,and collagen deposition were significantly reduced in each treatment group compared with those in the model group,and the degree of fibrosis was reduced.Serum ALT,AST,HA,LN,PCⅢ,and COL4 were significantly decreased and ALB was significantly increased,while liver levels of HIF-1α,Notch1,Jagged1,and α-SMA proteins were also significantly decreased to varying degrees(P＜0.05).In the in vitro experiments,hypoxia promoted HSC-T6 migration and reduced apoptosis,increased the protein expression levels of HIF-1α,Notch1,Jagged1,α-SMA,and TIMP-1,and reduced the expression levels of MMP9(P＜0.01).Serum containing Jiawei Jisheng Shenqi Decoction inhibited HSC-T6 migration,promoted HSC-T6 apoptosis,lowered the expression of HIF-1α,Notch1,Jagged1,α-SMA,and TIMP-1 proteins,and enhanced the expression of MMP9 protein(P＜0.01).The inhibitory effect of Jiawei Jisheng Shenqi on HSC-T6 cell activation was reversed by the HIF-1α agonist dimethyloxalylglycine.Conclusions Jiawei Jisheng Shenqi Decoction can improve the hypoxic microenvironment via the HIF-1α/Notch pathway,thereby exerting an anti-liver cirrhosis effect.

Objective:To investigate the influencing factors on the acceptance of intermittent oro-esophageal tube feeding (IOE) in patients with dysphagia after stroke (DAS) .Methods:A convenience sampling method was used to select 260 DAS patients hospitalized in the Second Affiliated Hospital of Wenzhou Medical University from February 2022 to March 2024. The Visual Analog Scale (VAS) was applied to evaluate patients' acceptance of IOE. Additionally, the General Information Questionnaire, IOE Knowledge Questionnaire, Health Information Literacy Self-assessment Scale, Nurse-patient Relationship Trust Scale, and Family APGAR Index (APGAR) were used for investigation. Multiple linear regression was performed to analyze the influencing factors of IOE acceptance in DAS patients.Results:A total of 260 questionnaires were distributed, and 246 valid questionnaires were recovered, with a valid recovery rate of 94.62% (246/260). The results of multiple linear regression analysis showed that the Water Swallowing Test grade, IOE Knowledge Questionnaire score, Health Information Literacy Self-assessment Scale score, Nurse-patient Relationship Trust Scale score, and APGAR score were influencing factors for IOE acceptance in DAS patients ( P<0.05) . Conclusions:The influencing factors of IOE acceptance in DAS patients include the severity of dysphagia, IOE knowledge, health information literacy, nurse-patient relationship trust, and family care. Targeted interventions can be implemented based on these factors to promote the popularization of IOE.
