ObjectiveTo investigate whether Danggui Shaoyaosan (DSS) inhibits oxidative stress and alleviates inflammation via the Ras homolog family member A (RhoA)/Rho-associated coiled-coil containing protein kinase 1 (ROCK)/nuclear factor kappa-B (NF-κB) signaling pathway, thereby delaying the progression of diabetic kidney disease (DKD) and exerting a nephroprotective effect. MethodsEight db/m mice were assigned to the normal group, and forty 8-week-old db/db mice were randomly divided into the model group, DSS low-dose group (8.39 g·kg-1), DSS medium-dose group (16.77 g·kg-1), DSS high-dose group (33.54 g·kg-1), and irbesartan group (0.025 g·kg-1), with eight mice in each group. All groups were administered the corresponding treatment by gavage once daily for 12 weeks. The normal and model groups received an equal volume of saline. During administration, changes in body weight, fasting blood glucose (FBG), and 24 hour urinary protein (24 h UTP) were observed. After 12 consecutive weeks of administration, hematoxylin-eosin (HE) staining and Masson's trichrome staining were used to observe renal histopathological changes in each group. The levels of reactive oxygen species (ROS) in renal tissue were detected using the dihydroethidium (DHE) method. The expression levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in renal tissue were determined. Serum interleukin-1β (IL-1β) and interleukin-6 (IL-6) levels were measured using enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of RhoA, ROCK1, and NF-κB p65 in renal tissues were detected by Real-time quantitative polymerase chain reaction (Real-time PCR). Protein expression levels of fibronectin (FN), Collagen Ⅳ(Col Ⅳ), transforming growth factor-β1 (TGF-β1), RhoA, ROCK, and NF-κB p65 in renal tissues were determined by Western blot. ResultsCompared with the normal group, the model group showed significantly increased body weight, FBG, and 24 h UTP levels (P<0.01), elevated serum IL-1β and IL-6 levels, enlarged glomerular volume, diffuse mesangial expansion, increased mesangial matrix, and marked collagen fiber proliferation in renal tissues. SOD activity was decreased, while MDA, ROS, RhoA, ROCK1, and NF-κB p65 mRNA expression levels were increased (P<0.01), and the protein expression levels of FN, Col Ⅳ, TGF-β1, RhoA, ROCK, and NF-κB p65 were also elevated (P<0.01). Compared with the model group, the DSS low-, medium-, and high-dose groups and the irbesartan group showed reductions in body weight, FBG, and 24 h UTP, decreased serum IL-1β and IL-6 levels, varying degrees of improvement in renal histopathology, increased SOD activity, decreased MDA levels, reduced ROS expression, and significantly downregulated RhoA, ROCK1, and NF-κB p65 mRNA expression (P<0.05, P<0.01), as well as reduced protein expression levels of FN, Col Ⅳ, TGF-β1, RhoA, ROCK, and NF-κB p65 (P<0.05, P<0.01). ConclusionDSS can alleviate oxidative stress and inflammation, reduce extracellular matrix deposition, and delay renal fibrosis progression in db/db mice. Its mechanism may be related to the inhibition of the RhoA/ROCK/NF-κB signaling pathway, thereby exerting a therapeutic effect on DKD.

Platelets are indispensable for physiological hemostasis and pathological thrombus formation, and platelet adhesion to endothelial collagen is a critical initial step in thrombus formation, often overlooked in current antiplatelet therapies. This study aims to elucidate how ginsenoside CK enhances hemodynamic circulation, alleviates stasis, and proposes therapeutic mechanisms. Inspired by the effects on improving microcirculatory disturbances in an acute soft tissue injury model, CK was identified as a PHD2 inhibitor, effectively suppressing platelet adhesion to collagen. It was proposed that targeting PHD2 regulates collagen hydroxylation modification, thereby influencing the formation of its three-dimensional structure, reducing the binding affinity between VWF and collagen, and ultimately suppressing thrombotic events. The efficacy of this mechanism was subsequently confirmed through a mouse DIC model, demonstrating the feasibility of CK in alleviating circulatory disorders. It is worth noting that when Phd2 was knocked down in mice's lungs, pulmonary embolism was significantly reduced. Additionally, PHD2 inhibitors approved for other diseases have exhibited similar anti-thrombotic effects. Moreover, when PHD2 inhibitors were combined with aspirin, they more effectively inhibited arterial thrombosis in rats. The findings offer valuable insights into potential targets for developing antiplatelet drugs or expanding therapeutic applications for existing PHD2 inhibitors in treating thrombotic diseases.

Objective To compare the gut fungal composition between gout patients and healthy individuals through high-throughput sequencing of ribosomal DNA internal transcribed spacer 1(ITS1).Methods Gout patients and healthy volunteers who visited our hospital from January 2023 to December 2024 were enrolled in this study.Then based on established medical guidelines,the gout patients were categorized into 3 groups:Group H(asymptomatic hyperuricemia,n=14),Group G(acute gouty arthritis,n=14),and Group I(intercritical period of gouty arthritis,n=15),and the healthy individuals were assigned into Group N(n=9).Fecal samples were collected from all the participants to undergo ITS1 sequencing analysis.The differences in diversity and composition of gut mycobiome,and FunGuild-derived fungal functions and nutritional status were compared among the 4 groups,and the correlation between the gut mycobiome and clinical indicators was analyzed.Results There were no significant differences in baseline features such as gender,age,glomerular filtration rate(GFR),and levels of serum creatinine(SCr)and serum urea among Group N and other gout groups,but obvious differences were observed in body mass index(BMI),erythrocyte sedimentation rate,and levels of C-reactive protein(CRP),serum uric acid(SUA),and IL-1β and IL-6(P<0.05).In terms of gut fungal diversity,ITS1 analysis showed there were no statistical differences in α-diversity or the principal coordinate analysis(PCoA)of β-diversity among the groups.However,as gout progressed,significant changes were observed in β-diversity indices,indicating a shift in the gut fungal community composition with disease advancement(P<0.05).The phyla Ascomycota,Basidiomycota,and Mucoromycotina were the dominant fungal phyla in all groups.Compared with the other 3 gout groups,the abundance of Pichia was significantly increased in Group N(P<0.05),that of Saccharomyces was in Group H(P<0.05),and that of Starmerella was in Group G(P<0.05).Correlation analysis between the gut mycobiome and clinical indices indicated that the relative abundance of Starmerella was significantly positively correlated with IL-1β(P<0.01)and IL-6(P<0.05).The relative abundance of Pichia was significantly positively correlated with IL-1β and IL-6 levels(P<0.05),and negatively correlated with serum urea level(P<0.05),and the relative abundance of Saccharomyces was negatively correlated with IL-1β and IL-6 levels(P<0.05).Conclusion There exist significant alterations in both the diversity and composition of gut fungi among patients with gout at various stages.Notably,the fluctuations in the relative abundance of Starmerella,Pichia and Saccharomyces appear to correlate with key clinical indicators.

Objective To explore the relationship between postoperative defecation dysfunction and quality of life in children with anorectal malformation(ARM)complicated with spinal cord anomalies(SCA)and analyze the impact of different types of SCA on ARM patients in order to provide a reference for the early clinical identification of high-risk children with poor prognosis.Methods A retrospective analysis was conducted on 282 ARM neonates admitted to our department between June 2015 and April 2021.Radiological examinations were applied to evaluate the development of the spinal cord,and Rintala score and the PedsQL 4.0 scale were employed to assess postoperative defecation function and quality of life,respectively.According to their SCA types and other complications,the patients were grouped.The relationship between these factors and defecation function as well as quality of life was then analyzed.Results Among the 282 subjected children,104(36.9%)had SCA.The incidence of SCA varied significantly across different types of ARM(P=0.002),with the highest incidence observed in vaginal fistula patients(100.0%)and the lowest in children without fistula(13.6%).Radiological findings revealed that sacral bone anomalies were common,with absent coccyx(62.7%)and vertebral anomalies(69.8%)being the most prevalent.The SCA group had significantly lower Rintala bowel function score(12.70±3.24)and PedsQL 4.0 quality of life score(81.42±5.03)than the non-SCA group(P<0.001).As the increment of SCA types,both the Rintala score and PedsQL 4.0 score were in a significant downward trend(P<0.001).Among the children with different types of SCA,those with tethered cord syndrome had the statistically lowest Rintala score(8.05±2.35,P<0.05).Meanwhile,their PedsQL 4.0 score(75.90±3.35)was significantly lower than those of other types except syrinx(P<0.05).Multiple linear regression analysis indicated that both SCA and sacral bone anomalies exerted notably negative impacts on the Rintala score and PedsQL 4.0 score(P≤0.001),with SCA having the most pronounced effect.Conclusion SCA is closely associated with postoperative defecation dysfunction and diminished quality of life in ARM children.The greater the type and number of SCAs,the worse the postoperative defecation function and quality of life.Early identification of concomitant SCAs holds significant clinical value for predicting postoperative outcomes in ARM patients.
