Adipose tissue is a critical energy reservoir in animals and humans, with multifaceted roles in endocrine regulation, immune response, and providing mechanical protection. Based on anatomical location and functional characteristics, adipose tissue can be categorized into distinct types, including white adipose tissue (WAT), brown adipose tissue (BAT), beige adipose tissue, and pink adipose tissue. Traditionally, adipose tissue research has centered on its morphological and functional properties as a whole. However, with the advent of single-cell transcriptomics, a new level of complexity in adipose tissue has been unveiled, showing that even under identical conditions, cells of the same type may exhibit significant variation in morphology, structure, function, and gene expression——phenomena collectively referred to as cellular heterogeneity. Single-cell transcriptomics, including techniques like single-cell RNA sequencing (scRNA-seq) and single-nucleus RNA sequencing (snRNA-seq), enables in-depth analysis of the diversity and heterogeneity of adipocytes at the single-cell level. This high-resolution approach has not only deepened our understanding of adipocyte functionality but also facilitated the discovery of previously unidentified cell types and gene expression patterns that may play key roles in adipose tissue function. This review delves into the latest advances in the application of single-cell transcriptomics in elucidating the heterogeneity and diversity within adipose tissue, highlighting how these findings have redefined the understanding of cell subpopulations within different adipose depots. Moreover, the review explores how single-cell transcriptomic technologies have enabled the study of cellular communication pathways and differentiation trajectories among adipose cell subgroups. By mapping these interactions and differentiation processes, researchers gain insights into how distinct cellular subpopulations coordinate within adipose tissues, which is crucial for maintaining tissue homeostasis and function. Understanding these mechanisms is essential, as dysregulation in adipose cell interactions and differentiation underlies a range of metabolic disorders, including obesity and diabetes mellitus type 2. Furthermore, single-cell transcriptomics holds promising implications for identifying therapeutic targets; by pinpointing specific cell types and gene pathways involved in adipose tissue dysfunction, these technologies pave the way for developing targeted interventions aimed at modulating specific adipose subpopulations. In summary, this review provides a comprehensive analysis of the role of single-cell transcriptomic technologies in uncovering the heterogeneity and functional diversity of adipose tissues.

Objective To analyze the the differences in the use of medical consumables of single diseases,so as to provide ideas for the supervision of the rational use of medical consumables.Methods The case information of the patients discharged from some hospital in Hunan Province who underwent artificial femoral head replacement for femoral neck fracture,transurethral plasma electrosurgery for prostatic hyperplasia and percutaneous nephrolithotripsy for renal calculi from January 1,2022 to December 31,2023 were selected.Based on the results of the normality test,difference analyses were carried out over the consumption ratios of inpatients undergoing different procedures at different time periods and the consumption ratios treated by different physicians,and the percentile method was used to determine the recommended range for the consumption ratio based on the difference analysis results.SPSS 26.0 software was used for statistical analysis.Results The inpatients undergoing artificial femoral head replacement for femoral neck fracture at different periods had no significant difference in the consumption ratio(P>0.05);the inpatients going through transurethral plasma electrosurgery for prostatic hyperplasia had the consumption ratio in 2023 decreased by 5.22%when compared with that in 2022,with the difference being statistically significant(P<0.05);the inpatients undergoing percutaneous nephrolithotripsy for renal calculi had the consumption ratio at 2023 increased by 6.49%when compared with that at 2022,with the difference being statistically significant(P<0.05).There were no strong correlations between physician and inpatient consumption ratios for the three single-diseases(P<0.05),while the consumption ratios by different physicians for each single disease had differences.There were respectively 50%,40%and 50%of the physicians implementing artificial femoral head replacement for femoral neck fracture,transurethral plasma electrosurgery for prostatic hyperplasia and percutaneous nephrolithotripsy for renal calculi had the average consumption ratios higher than the average annual consumption ratios for the single diseases.The recommended ranges of the consumption ratio was[51.16%,63.89%]for artificial femoral head replacement for femoral neck fracture,[8.76%,10.77%]for transurethral plasma electrosurgery for prostatic hyperplasia and[26.40%,32.80%]for percutaneous nephrolithotripsy for renal calculi.Conclusion Under the premise of ensuring the quality of medical care,medical consumables can be scientifically and rationally supervised by setting a reasonable range,seizing the"vital few"and implementing joint management and control to reduce the consumption ratio.[Chinese Medical Equipment Journal,2025,46(7):87-91]
