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.

ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure (HBV-ACLF) at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients, including 618 in the early stage, 355 in the middle stage, and 85 in the late stage, were collected from 18 clinical centers across 12 regions nationwide from January 1, 2012 to February 28, 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients, like the four diagnostic information (including symptoms, tongue, pulse) of traditional Chinese medicine (TCM), and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients, and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries, including 36 symptom information, 12 tongue information, and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF, which were liver-gallbladder damp-heat pattern, qi deficiency and blood stasis pattern, liver-kidney yin deficiency pattern, and spleen-kidney yang-deficiency pattern. In the early stage, heat (39.4%, 359/912) and dampness (27.5%, 251/912) were most common, and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern (74.6%, 461/618); in the middle stage, dampness (30.2%, 187/619) and blood stasis (20.7%, 128/619) were most common, and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern (53.2%, 189/355), and qi deficiency and blood stasis pattern (27.6%, 98/355); and in the late stage, the pattern of the disease was dominated by qi deficiency (26.3%, 40/152) and yin deficiency (20.4%, 31/152), and the patterns were dominated by qi deficiency and blood stasis pattern (36.5%, 31/85), and liver-gallbladder damp-heat pattern (25.9%, 22/85). ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF, presenting an overall trend of evolving patterns as "from excess to deficiency, transforming from excess to deficiency", which is damp-heat → blood stasis → qi-blood yin-yang deficiency.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine (TCM) mainly involves peripheral vestibular diseases of Western medicine, such as Meniere's disease, benign paroxysmal positional vertigo, vestibular neuritis, and vestibular migraine, being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo, aural vertigo affecting the quality of life, aural vertigo not relieved after surgery, aural vertigo with complex causes, and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM: Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo, the control and mitigation of the symptoms, and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

OBJECTIVE To investigate the improvement effects of 3,5,6,7,8,3′,4′-heptamethoxyflavone (HMF) of Fructus Aurantii on rats with damp blockage of the middle energizer. METHODS The rats were randomly divided into normal group, model group, positive control group (Raceanisodamine tablet, 1 mg/kg), HMF low-dose, medium-dose and high-dose groups (0.3, 0.6, 0.9 mg/kg), with 7 rats in each group. Except for the normal group, the other groups were modeled by internal and external composite factors. After successful modeling, the rats in each group were given the corresponding drug or normal saline, once a day, for 14 days. The general behavioral states such as dietary intake, water intake and mental state of the rats were observed, and the fecal water content rate and saliva flow rate were measured. Hematoxylin-eosin (HE) staining was used to observe the pathological and morphology in gastric and small intestinal tissues of rats. The plasma content of aldosterone was detected, and the expression of aquaporins (AQP3) in the gastric tissue of rats was determined. RESULTS Compared with the normal group, the dietary intake and water intake of the model group rats were significantly decreased (P<0.01), the fecal water content rate, salivary flow rate, plasma content of aldosterone and the expression of AQP3 in gastric tissue were increased significantly (P<0.01). Gastric tissue injury invaded the mucosal muscle layer, resulting in mucosal muscle layer rupture; pathological and morphological changes such as small intestinal villous erosion and glandular structure destruction were observed in the small intestine. Compared with the model group, the dietary intake and water intake of rats were increased in HMF groups; fecal water content rate, salivary flow rate, plasma content of aldosterone, the expression of AQP3 in gastric tissue were decreased, most of the above differences were statistically significant (P<0.05 or P<0.01). The pathological and morphological changes in the gastric and small intestine tissues of rats had been improved to varying degrees. CONCLUSIONS HMF of Fructus Aurantii with dry property HMF could improve the symptoms of rats with damp blockage of middle energizer, the mechanism of which may be associated with reducing the content of plasma aldosterone and down-regulating the expression of gastric AQP3.
