Hypercholesterolemia (HCh) represents a prevalent comorbidity in patients with diabetic foot ulcers (DFUs), frequently exacerbating wound recalcitrance, yet the mechanisms linking systemic lipid perturbation to local immune dysregulation remain poorly defined. Here, we applied an integrated transcriptomic and machine learning approach to explore the molecular basis of this comorbidity. Initial analyses identified 70 shared DEGs between DFUs and HCh, primarily enriched in pathways related to lipid homeostasis disruption and inflammatory cascade activation. Subsequently, a four-algorithm machine learning pipeline highlighted AKR1C3 and CLIC3 as candidate diagnostic biomarkers, both consistently downregulated across disease states and supported by independent external validation cohorts (AUC = 0.779 and 0.920). Immune deconvolution further indicated a dysregulated microenvironment featuring sustained innate immune activation alongside adaptive immune impairment, which correlated with reduced AKR1C3 and CLIC3 expression. Drug repurposing analyses proposed that pirfenidone and statins might attenuate this pathological transcriptomic signature, while molecular docking simulations suggested stable binding of exemestane and indomethacin to AKR1C3 (binding energies: -8.0 and -7.3 kcal/mol, respectively). Collectively, these findings suggest that AKR1C3 and CLIC3 act as molecular bridges linking the TGF-β/lipid metabolism axis to local immune dysfunction, offering a rationale for early risk stratification and targeted drug repurposing in DFUs-HCh comorbidity.

Objective:To explore the clinical efficacy of Badu Shengji Powder in the treatment of chronic refractory wounds.Methods:China National Knowledge Infrastructure(CNKI),China Science Periodical Database(CSPD),Chinese Citation Database(CCD),China Biology Medicine(CBM),American Medicine Database(Medicine),and the Cochrane Library were searched for clinical randomized controlled trials(RCTs) on the efficacy of Badu Shengji Powder in treating chronic refractory wounds by keywords from database inception to October 2022.After two investigators screened the literature in accordance with inclusion and exclusion criteria, extracted the data, and evaluated the risk of bias of included studies, RevMan5.3 software was used for systematic evaluation and Meta-analysis.Results:Fourteen RCTs were included, with 787 patients involved, i.e.,394 patients in the treatment group and 393 patients in the control group.Meta-analysis showed that the wound healing rate in the treatment group was higher than that in the control group(OR=4.08,95%CI 2.55 to 6.55,P<0.000 01).The effective rate of wounds in the treatment group was higher than that in the control group(OR=6.08,95%CI 3.45 to 10.73,P<0.000 01).The wound healing time in the treatment group was shorter than that in the control group(MD=-3.07,95%CI-4.12 to-2.03,P<0.000 01).The pain score of the treatment group was lower than that of the control group(MD=-1.18,95%CI-2.03 to-0.33,P=0.006).Conclusion:The current evidence shows that the clinical application of Badu Shengji Powder can improve the healing rate of chronic refractory wounds and the effective rate, shorten the healing time of wounds, and relieve pain.However, due to the limitations of the studies included, the above conclusion still needs more high-quality research validation.
ABSTRACT The gut microbiota is an important risk factor and therapeutic target in atherosclerotic cardiovascular disease (ACVD), a leading cause of morbidity and mortality worldwide. However, alterations in the gut viral community and its contribution to ACVD have rarely been investigated. In this study, we characterized and compared the gut viromes from the fecal metagenomes of 214 patients with ACVD and 171 healthy individuals using a reference-dependent virome approach. We revealed that ACVD patients exhibited a significant increase in viral richness at the family level and a visible alteration in overall virome structure regardless of host sex, age, or body mass index. At the viral operational taxonomic unit (vOTU) level, we identified 105 vOTUs that significantly increased in abundance in ACVD patients and 60 vOTUs that increased in abundance in healthy controls. A majority (43.8%) of the ACVD-enriched vOTUs were predicted to infect Streptococcaceae, Lachnospiraceae, Ruminococcaceae, and Enterobacteriaceae, and Streptococcaceae had tight correlations with the corresponding gut bacterial species, whereas a considerable proportion (35.0%) of the control-enriched vOTUs were Bacteroidaceae, Burkholderiaceae, and Lachnospiraceae phages. Functional analyses revealed five viral auxiliary metabolic genes that differed in frequency between ACVD-enriched and control-enriched vOTUs. Moreover, we identified gut viral signatures for ACVD discrimination and achieved an optimal area under the receiver operator characteristic curve of 0.878 for distinguishing patients from healthy controls. Our results provide a comprehensive view of the ACVD gut virome, which may contribute to the development of novel diagnostic and therapeutic strategies for ACVD and additional relevant cardiovascular diseases. IMPORTANCE Existing studies have found that there is a close relationship between human virome and numerous diseases, and diseases may affect the diversity and composition of the virome; at the same time, changes in the virome will in turn affect the onset and progression of the disease. However, the composition and functional capabilities of the gut virome associated with atherosclerotic cardiovascular disease (ACVD) have not been systematically investigated. To our knowledge, this is the first study investigating the gut virome in patients with ACVD. We characterized the structural changes in the gut virome of ACVD patients, which may facilitate additional mechanistic, diagnostic, and interventional studies of ACVD and related diseases.
Panax notoginseng saponins (PNSs) have been found as the major active ingredient of Panax notoginseng (Burkill) F.H.Chen (PN) leaves, which has the effect of reducing inflammatory response, facilitating fibroblast proliferation, as well as promoting angiogenesis. This study aimed to investigate the molecular basis of PNS combined with bone mesenchymal stem cells (BMSCs) for treating diabetic cutaneous ulcers (DCU) and its mechanism of action. Methods. A total of 75 SD rats were selected to make diabetic cutaneous ulcers model. According random number table method, the rats were randomly divided into a control group, a DCU group, a BMSCs group, a PNS group and BMSCs + PNS group. Five groups of rats were given without treatment. After being treated for 7 days, the rats were anesthetized with pentobarbital, and granulation tissue was collected from the central point of the wound. They were used for pathological analysis, Western blot (WB) and polymerase chain reaction (PCR) assays. Results. The wound healing area was the largest in the BMSCs + PNS group. HE staining results showed that the PNS + BMSCs group could promote the formation of new epidermis and reduce the infiltration of inflammatory cells. Immunohistochemistry (IHC) results showed that the PNS + BMSCs group could up-regulate the expression of Ki67 protein and cell proliferation. In addition, PNS combined with BMSCs up-regulated the expression of miR-146-5p and down-regulated the expression of IL-1β, IL-6 and TNF-α, IRAK1, TRAF6 and p65 in the NF-κB signaling pathway (p < 0.05). Conclusions. PNS combined with bone mesenchymal stem cell transplantation up-regulated miR-146a-5p targeting and binding to IRAK1/TRAF6, inhibiting the activation of NF-κB pathway, which reduced the inflammatory response of DCU and facilitated the skin healing of DCU. Thus, this study provides a theoretical basis and a novel therapeutic option for the treatment of DFU with PNS combined with BMSCs.

OBJECTIVE In this study, we aimed to evaluate the possible function of miR-130a in atherosclerosis (AS), protection against AS, and its molecular biological mechanism. METHODS Apoe-/- mice were fed a high-fat diet as the AS mice model. Human umbilical vein endothelial cells (HUVECs) were used as in vitro model. Serum samples or cells were used to measure the expression of inflammation. Serum samples or cells were used to determine MiRNA expression profiles using the edgeR tool from Bioconductor. Western Blot analysis was used to assess protein expressions of proliferator-activated receptor γ (PPARγ) and nuclear factor (NF)-κB. RESULTS MiRNA-130a expression was up-regulated in atherosclerotic mice. In addition, over-expression of miRNA-130a promoted inflammation factors [tumor necrosis factor (TNF)-α and interleukin (IL)-1β, IL-6, and IL-8] in the in vitro model of AS. However, down-regulation of miRNA-130a reduced inflammation (suppressed TNF-α, IL-1β, IL-6 and IL-8) in the in vitro model. Furthermore, over-expression of miRNA-130a could also suppress the protein expression of PPARγ and induce NF-κB protein expression in the in vitro model. However, suppression of miRNA-130a induced the protein expression of PPARγ and suppressed NF-κB protein expression in the in vitro model of AS. Activation of PPARγ reduced the pro-inflammatory effects of miRNA-130a on the AS-induced in vitro model. CONCLUSION These results strongly support that miRNA-130a suppression can protect against atherosclerosis through inhibiting inflammation by regulating the PPARγ/ NF-κB expression.
