Objective:To analyze the immune microenvironment characteristics of human dental follicle tissues from the third molars and to explore the mutual communication and the effects of innate immune cells and adaptive immune cells within the dental follicle.Methods:Sequencing data(GSA-Human:HRA008022)in the GSA database were analyzed.Bioinformatics tools were employed for gene identification and GO enrichment analysis was performed to define the biological function of innate and adaptive immune cells.CellChat analysis was used for explaining intercellular communication among immune cell populations.Results:Using t-SNE dimen-sionality reduction analysis for immune cell populations,innate immune cell populations were obtained,including innate lymphoid cells,dendritic cells,mast cells and macrophages,and adaptive immune cell populations including T cells and B cells.Pearson corre-lation analysis showed that innate immune cells,specifically innate lymphoid cells and macrophages,had a strong correlation with adap-tive immune cell populations.GO enrichment analysis revealed mutual coordination among innate immune cell populations and regulato-ry effects on adaptive immune cell populations.Further CellChat analysis indicated biological signal transmission between innate and a-daptive immune cell populations,with CLEC,MIF,ADGRE5,COLLAGEN and MIF signaling pathways is the most significant.Con-clusion:Dental follicle tissues are rich in immune cells and innate immune cell populations interact with adaptive immune cells to regulate immune responses and participate in maintaining the homeostasis of dental follicle.

Objective To evaluate the pharmacokinetics characteristics of single-dose of Etripamil nasal spray 70 mg in healthy adult Chinese subjects.Methods This was a single-center,randomized,double-blind,placebo-controlled study.Twelve healthy adult Chinese subjects were randomized to receive single-dose of Etripamil nasal spray 70 mg(n=10)or placebo nasal spray(n=2).Blood and urine samples were collected prior and post dose.Etripamil in plasma and urine were analyzed by liquid chromatography-tandem mass spectrometry.The pharmacokinetic parameters were calculated by WinNonlin non-compartmental model.Results Following the single-dose of Etripamil nasal spray 70 mg in healthy adult Chinese subjects,the peak concentration of Etripamil in plasma was quickly attained,with a Cmax of(66.76±56.61)ng·mL-1 and a median(range)tmax of 4.00(3.00-5.00)min.The plasma concentrations of Etripamil had fallen approximately 65％from peak value at 25 min after dosing,and close to 80％within 50 min.The AUC0-last and AUC0-∞ were(3 104.16±2 654.46)and(4 048.77±2 682.38)ng·min·mL-1,respectively.The urine excretion percentage of Etripamil during 24 h was(0.01±0.01)％.Among the 12 subjects who were treated with Etripamil or placebo,10 subjects reported a total of 29 treatment-emergent adverse events(TEAEs).All of the TEAEs were mild in severity.The most common TEAEs were rhinorrhoea and lacrimation increased.Conclusion Etripamil was quickly absorbed after intranasal administration,followed by rapid distribution and elimination(not primarily excreted by renal);Etripamil 70 mg was safe and well tolerated by the healthy Chinese adult subjects.

ObjectiveTemporal heterogeneity in lung cancer presents as fluctuations in the biological characteristics, genomic mutations, proliferation rates, and chemotherapeutic responses of tumor cells over time, posing a significant barrier to effective treatment. The complexity of this temporal variance, coupled with the spatial diversity of lung cancer, presents formidable challenges for research. This article will pave the way for new avenues in lung cancer research, aiding in a deeper understanding of the temporal heterogeneity of lung cancer, thereby enhancing the cure rate for lung cancer. MethodsRaman spectroscopy emerges as a powerful tool for real-time surveillance of biomolecular composition changes in lung cancer at the cellular scale, thus shedding light on the disease’s temporal heterogeneity. In our investigation, we harnessed Raman spectroscopic microscopy alongside multivariate statistical analysis to scrutinize the biomolecular alterations in human lung epithelial cells across various timeframes after benzo(a)pyrene exposure. ResultsOur findings indicated a temporal reduction in nucleic acids, lipids, proteins, and carotenoids, coinciding with a rise in glucose concentration. These patterns suggest that benzo(a)pyrene induces structural damage to the genetic material, accelerates lipid peroxidation, disrupts protein metabolism, curtails carotenoid production, and alters glucose metabolic pathways. Employing Raman spectroscopy enabled us to monitor the biomolecular dynamics within lung cancer cells in a real-time, non-invasive, and non-destructive manner, facilitating the elucidation of pivotal molecular features. ConclusionThis research enhances the comprehension of lung cancer progression and supports the development of personalized therapeutic approaches, which may improve the clinical outcomes for patients.
