Diabetic retinopathy (DR) is a microvascular complication of diabetes and one of its most common complications. Prolonged hyperglycemia induces oxidative stress, inflammatory responses, apoptosis, and pathological angiogenesis, ultimately disrupting the blood-retinal barrier(BRB) and leading to visual impairment or even blindness. Recent studies show that the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway plays an important role in the development of DR's pathological changes. Meanwhile, Chinese herbal monomers have been shown to modulate the Nrf2 signaling pathway, thereby intervening in the development of DR. In terms of inhibiting oxidative stress, saponin compounds such as platycodin-D and ginsenoside Rb1 downregulate the expression of malondialdehyde (MDA), thereby ameliorating retinal oxidative stress. Flavonoids such as total flavonoids from Pueraria lobata flower and puerarin upregulate the expression of superoxide dismutase (SOD) and glutathione peroxidase (GPx), effectively clearing lipid peroxides. Regarding the suppression of inflammation, phenolic compounds like resveratrol and chlorogenic acid inhibit the nuclear factor kappa B (NF-κB) pathway, reducing the release of tumor necrosis factor-alpha (TNF-α) and mitigating inflammatory responses. In the context of inhibiting apoptosis, polysaccharides such as Polygonatum sibiricum polysaccharide and Angelica sinensis polysaccharide downregulate the expression of the pro-apoptotic protein Bcl-2-associated X protein (Bax) and suppress the activity of the executioner Caspase-3, thereby reducing the apoptosis rate. As for the inhibition of neovascularization, compounds including bilobalide and physcion significantly decrease the protein expression of vascular endothelial growth factor (VEGF), leading to a reduction in retinal pathological angiogenesis. Furthermore, Chinese herbal compound prescriptions such as Tongluo Zhujing pills, Yiqi Huoxue Yangyin decoction, Qiming granules, and Danlou tablets can also intervene in the onset and progression of DR through the mechanisms described above. In summary, both Chinese herbal monomers and Chinese herbal compound prescriptions can modulate the Nrf2 signaling pathway to inhibit oxidative stress, alleviate inflammation, and participate in maintaining BRB integrity, suppressing retinal neovascularization, and preventing neurodegeneration, thereby delaying the progression of DR. Therefore, this paper reviews and summarizes recent studies at home and abroad on how traditional Chinese medicine (TCM) works to treat DR, and the relationship between the Nrf2 pathway and DR. It aims to provide research ideas for preventing and treating DR.

Objective :
To analyze the correlation between different laboratory biomarkers and disease activity in ankylosing spondylitis and to compare their specificity and sensitivity in assessing disease activity.
Methods :
Spearman correlation or Pearson correlation was used to analyze the correlation between disease activity and laboratory biomarkers. Receiver operating characteristic(ROC) was used to compare the sensitivity and specificity of each laboratory biomarker in evaluating disease activity.
Results :
Hypersensitive C-reactive protein, fibrinogen, D-dimer, erythrocyte sediment rate, C-reactive protein, immuno-inflammatory index(platelet count×neutrophil count/lymphocyte count), fibrinogen/albumin ratio, albumin and pro-albumin were correlated with disease activity. The ratio of fibrinogen to albumin, fibrinogen, erythrocyte sedimentation rate, immuno-inflammatory index, C-reactive protein and hypersensitive C-reactive protein had good values in determining the disease activity.
Conclusion
Different laboratory biomarkers are correlated with the disease activity of ankylosing spondylitis, and some of them have better discriminating values for the disease activity.

A portable molecularly imprinted(MIP)surface-enhanced Raman scattering(SERS)chip was fabricated via a green electrochemical approach for highly selective detection of bisphenol A(BPA).This MIP-AuNP/UIO-66/SPE sensor was fabricated through a single-step co-deposition process.The process involved electropolymerization onto a UIO-66 modified screen-printed electrode(SPE),by usingo-phenylenediamine(OPD)as functional monomer and BPA as template,and simultaneously electro-reduction generated gold nanoparticles(AuNPs),which served as the SERS-active substrate.Ultimately,this one-step method formed a three-dimensional porous architecture on the electrode surface.Under 785 nm laser excitation,the sensing chip exhibited a highly sensitive SERS response towards BPA.The intensity of its characteristic peak at 850 cm-1 showed a good linear relationship with logarithm of BPA concentration in the range of 1.0×10-10 to 1.0×10-6 mol/L,with a detection limit of 1.0×10-12 mol/L.More importantly,the fabricated chips maintained highly selective binding affinity for BPA in water samples even in the presence of structural analogs bisphenol F(BPF)and bisphenol S(BPS).When the chip was applied to detection of BPA in water samples from plastic bottle and paper cup,the recovery rates ranged from 94.0%to 103.0%with relative standard deviations(RSD)less than 4.7%.The developed chip offered a highly sensitive and selective solution for detection of trace BPA in complex water samples.

Aim To explore the impact and mechanism of proprotein convertase subtilisin kexin 9(PCSK9)on the progression of abdominal aortic aneurysm(AAA).Methods 6~8 week old ApoE-/-mice were selected to estab-lish the AAA model.Angiotensin Ⅱ(Ang Ⅱ)was continuously infused through subcutaneous implantation of a micro-os-motic pump.The mice were fed with high-fat diet and killed after 28 days.The expression of PCSK9 in abdominal aor-tic smooth muscle cells was detected by immunohistochemistry and immunofluorescence in normal abdominal aortic blood vessels and AAA samples in human and mice.Primary cultured murine vascular smooth muscle cells(mVSMC)of C57BL/6 mice were treated with different concentrations of AngⅡ for 24 h,and the expression of PCSK9 mRNA and pro-tein was detected.PCSK9 overexpression and knockdown cell models were established,and mitochondrial reactive oxygen species(mtROS),mitochondrial membrane potential(MMP),mitochondrial permeability transition pore(MPTP)open-ing,and Z-DNA binding protein 1(ZBP1)protein expression were detected.Bioinformatics was used to analyze the dif-ferential expression of multiple single-cell sequencing datasets to obtain the key differentially expressed genes,and to study their expression and role in AAA.Results Immunohistochemistry and immunofluorescence results showed that PCSK9 expression in human and mouse AAA increased(P<0.01),and co-localized with smooth muscle.Ang Ⅱ promoted PCSK9 expression in mVSMC in a concentration-dependent manner,the 2.0 μmol/L Ang Ⅱ group showed a 2.9-fold and 1.1-fold increase in the expression of PCSK9 mRNA and protein,respectively(P<0.01),with the most significant effect observed.After successfully constructing PCSK9 overexpression and PCSK9 interference mVSMC models,PCSK9 overex-pression led to an increase in intracellular mtROS,a decrease in MMP,an increase in MPTP opening,and a decrease in cellular activity(P<0.01);PCSK9 knockdown could reduce Ang Ⅱ induced increase in mtROS,decrease in MMP and MPTP opening;compared with the siNC+Ang Ⅱ group,the siPCSK9+Ang Ⅱ group showed a decrease in mtROS and an in-crease in the fluorescence brightness of MMP and MPTP(P<0.05).Bioinformatics analysis revealed that ZBP1 was a core differentially expressed gene in AAA.Immunohistochemistry and immunofluorescence results showed that ZBP1 ex-pression in human and mouse AAA tissues increased,and co-localized with smooth muscle.Western blot results showed that PCSK9 overexpression or treatment with 2.0 μmol/L Ang Ⅱ could increase ZBP1 protein expression(P<0.01),while PCSK9 knockdown could alleviate the increased ZBP1 expression caused by AngⅡ(P<0.05).Conclusion PCSK9 may induce mitochondrial damage in smooth muscle cells,activate downstream molecule ZBP1 to cause cell damage,and promote the development of AAA.

Background and aims:Despite growing evidence linking pretransplant exposure to immune checkpoint inhibitors(ICIs)to increased allograft rejection risk after liver transplantation(LT),a lack of comparative studies to definitively establish the correlation between ICI exposure and adverse short-term outcomes after LT exists.This study aimed to analyze the impact of preoperative ICI exposure on short-term post-LT prognosis and allograft rejection risk.Methods:This retrospective cohort study included 121 recipients who underwent LT for hepatocellular carcinoma(HCC)between June 2019 and March 2023.The recipients were categorized into ICI(n=35)and non-ICI(n=86)exposure groups based on pretransplant ICI exposure.Demographics,clinical characteristics,and short-term outcomes were compared between the cohorts.Kaplan-Meier analysis evaluated the impact of ICI exposure on graft survival.Univariate and multivariate logistic regression models assessed the impact of patient characteristics on allograft rejection.Results:Recipients with or without ICI exposure exhibited comparable demographic baseline charac-teristics.The incidences of early allograft dysfunction and biliary and vascular complications were similar between both groups.Post-transplant infection incidence was 37.1%and 20.9%in the ICI and non-ICI groups,respectively(P=0.064).Allograft rejection rates were significantly higher in the ICI group than in the non-ICI group(22.9%vs.5.8%,P=0.015).The ICI group exhibited a higher 90-day post-transplant mortality rate than that of the non-ICI group(14.3%vs.2.3%,P=0.034).Logistic regression analyses demonstrated that allograft rejection independently correlated with 90-day post-transplant mortality,with ICI exposure being an independent risk factor for allograft rejection.In recipients with ICI exposure,a shorter interval between ICIs and LT(washout period)was significantly associated with a higher allograft rejection risk,with the optimal washout period identified as 21 days for predicting 90-day rejection-free survival(P=0.0001).Moreover,in recipients with allograft rejection,the peripheral CD4+/CD8+T cell ratio was much lower in the ICI group than in the non-ICI group.Conclusions:Pretransplant ICI exposure was an independent risk factor for allograft rejection and was significantly associated with 90-day post-transplant mortality after LT for HCC.A ≤21-day washout period was significantly associated with allograft rejection.Future multicenter studies with larger cohorts and prospective designs are essential to validate these findings,confirm causality,and establish standardized clinical guidelines for ICI use before transplantation.Trail registration:ClinicalTrials.gov NCT05913583.
