Periodontal bone defects, primarily caused by periodontitis, are highly prevalent in clinical settings and manifest as bone fenestration, dehiscence, or attachment loss, presenting a significant challenge to oral health. In regenerative medicine, harnessing developmental principles for tissue repair offers promising therapeutic potential. Of particular interest is the condensation of progenitor cells, an essential event in organogenesis that has inspired clinically effective cell aggregation approaches in dental regeneration. However, the precise cellular coordination mechanisms during condensation and regeneration remain elusive. Here, taking the tooth as a model organ, we employed single-cell RNA sequencing to dissect the cellular composition and heterogeneity of human dental follicle and dental papilla, revealing a distinct Platelet-derived growth factor receptor alpha (PDGFRA) mesenchymal stem/stromal cell (MSC) population with remarkable odontogenic potential. Interestingly, a reciprocal paracrine interaction between PDGFRA+ dental follicle stem cells (DFSCs) and CD31+ Endomucin+ endothelial cells (ECs) was mediated by Vascular endothelial growth factor A (VEGFA) and Platelet-derived growth factor subunit BB (PDGFBB). This crosstalk not only maintains the functionality of PDGFRA+ DFSCs but also drives specialized angiogenesis. In vivo periodontal bone regeneration experiments further reveal that communication between PDGFRA+ DFSC aggregates and recipient ECs is essential for effective angiogenic-osteogenic coupling and rapid tissue repair. Collectively, our results unravel the importance of MSC-EC crosstalk mediated by the VEGFA and PDGFBB-PDGFRA reciprocal signaling in orchestrating angiogenesis and osteogenesis. These findings not only establish a framework for deciphering and promoting periodontal bone regeneration in potential clinical applications but also offer insights for future therapeutic strategies in dental or broader regenerative medicine.

ObjectiveTo study the effects of applying different microbial fertilizers on the growth and rhizosphere soil environment of Codonopsis pilosula and provide a theoretical basis for ecological cultivation of this medicinal plant. MethodsSeven groups were designed, including CK (no application of microbial fertilizer), T1 (Trichoderma longibrachiatum fertilizer), T2 (Bacillus subtilis fertilizer), T3 (Trichoderma viride fertilizer), T4 (compound microbial fertilizer), T5 (C. pilosula stems and leaves fermented with compound microbial fertilizer), and T6 (Scutellaria baicalensis stems and leaves fermented with T. viride fertilizer). The physiological indicators, yield, and quality of C. pilosula and the physicochemical properties, enzyme activities, and microbial diversity in the rhizosphere soil of different fertilizer treatments were measured. ResultsGroup T1 showed slight decreases in soluble protein content (SPC) and superoxide dismutase (SOD). Groups T2-T6 showed increases in physiological indicators such as proline (Pro), soluble solids content (SSC), SPC, catalase (CAT), and peroxidase (POD) and a decrease in malondialdehyde (MDA) in C. pilosula leaves. All the fertilizer treatments increased the yield of C. pilosula and the total polysaccharide content in the roots. T1, T2, T3, T4, and T5 increased the total flavonoid content in the roots. Meanwhile, T4 increased the total saponin content in the roots. All the fertilizer treatments reduced the pH and increased the electric conductivity (EC), soil organic matter (SOM), and alkaline nitrogen (AN) in the soil. T2 and T5 increased the available phosphorus (AP), and T3, T4, T5, and T6 increased the available potassium (AK) in the soil. All the fertilizer treatments increased the activities of urease, sucrase, and CAT in the soil. Except that T1 decreased the bacterial diversity in the soil, other fertilizer treatments significantly increased bacterial and fungal diversity in the soil. Different fertilizer treatments significantly affected the composition of bacterial and fungal communities in the soil. At the phylum level, the dominant bacterial phyla included Proteobacteria, Acidobacteriota, and Bacteroideta, and the dominant fungal phyla were Ascomycota, Mortierellomycota, and unclassified_fungi in the rhizosphere soil of C. pilosula after bacterial fertilizer treatment. At the genus level, unclassified Gemmatimonadaceae, Sphingomonas, and unclassified Vicinamibacteraceae were the dominant bacterial genera, while unidentified, unclassified Fungi, and unclassified Sordariomycetes were the dominant fungal genera in the rhizosphere soil. The results of redundancy analysis indicated that the main physicochemical factors affecting changes of microbial communities in the rhizosphere soil of C. pilosula were pH, EC, AK, AN, AP, and soil organic matter (SOM) in the soil. The correlation heatmap showed that Bryobacter had significantly positive correlations with EC, AK, and AN. There was a significantly negative correlation between Fusarium and SOM. In summary, applying an appropriate amount of microbial fertilizer can promote the growth and improve the rhizosphere soil environment of C. pilosula. ConclusionThe compound microbial fertilizer and the C. pilosula stems and leaves fermented with compound microbial fertilizer can improve the soil nutrients, growth, development, yield, and quality of C. pilosula, and thus they can be applied to the artificial cultivation of C. pilosula.

BACKGROUND:Osteoporosis is often accompanied by sarcopenia and an increased risk of fractures from falls.Recent studies have indicated a close relationship between lipid metabolism and sarcopenia.Abnormal lipid metabolism may directly impact muscle physiological function and metabolism. OBJECTIVE:To investigate the relationship between lipid metabolism and sarcopenia and evaluate their causal relationship using Mendelian randomization. METHODS:Mendelian randomization was used to explore the causal relationship between low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,triglycerides,and muscle mass.Research data from genome-wide association studies were used and a sensitivity analysis was conducted to verify the reliability of the results.Approximate indicators of muscle mass,including trunk lean mass and appendicular lean mass,were used as outcome measures. RESULTS AND CONCLUSION:The study found a negative correlation of low-density lipoprotein cholesterol and triglycerides with muscle mass,while no correlation was observed between high-density lipoprotein cholesterol and muscle mass.The results of the sensitivity analysis indicated a robust causal relationship.Using Mendelian randomization,this study provides evidence of a causal relationship between low-density lipoprotein cholesterol and triglycerides and muscle mass.This finding deepens our understanding of the effects of lipids on sarcopenia and has important clinical implications for the prevention and treatment of sarcopenia and osteoporosis.

Sepsis poses a major threat to human health due to its high morbidity and mortality.At present,there are still limitations to the comprehensive intervention plan for sepsis.Especially when sepsis progresses to the stage of septic shock,multiple organ dysfunction syndrome(MODS)or disseminated intravascular coagulation(DIC)and other critical conditions,there are no effective specific treatment methods,which makes sepsis a more severe syndrome.Traditional Chinese medicine has special advantages in participating in intervention and treatment of sepsis due to its holistic concept,syndrome differentiation and other treatment theories.Therefore,our team proposed to summarize the characteristics of traditional Chinese medicine syndrome in the critical stage of sepsis with the concept of"blood syndrome of sepsis",based on traditional Chinese medicine syndrome differentiation theoretical system and clinical experience summary.In this article,we summarized the modern research progress of the blood syndrome of sepsis from the perspectives of its pathogenesis and basic research.And we summarized its main clinical symptoms,explored its diagnosis and differential diagnosis from the perspective of conceptual analysis,and outlined and discussed the effective treatment principles and commonly used traditional Chinese medicine for this syndrome.It should be noted that endothelial injury plays an important role in the objective mechanism of blood syndrome of sepsis.The traditional Chinese medicine treatment with cooling blood and promoting blood circulation as the core principle may have a therapeutic effect on blood syndrome of sepsis through the protection of vascular endothelial function,and curb the trend of sepsis progressing to critical conditions such as shock,MODS,and DIC,ultimately improving the efficacy and prognosis of sepsis patients.We hope that our thinking and discussion could provide reference for the early identification and early treatment in the critical stage of sepsis,based on the theory of traditional Chinese medicine.
