As a famous tonic herb, Cistanches Herba is known for its broad medicinal functions, especially its hormone balancing, anti-aging, anti-dementia, anti-tumor, anti-oxidative, neuroprotective, and hepatoprotective effects. This study aims to provide a comprehensive bibliometric analysis of studies on Cistanche and to identify research hotspots and frontier topics on the genus. Based on the metrological analysis software CiteSpace, 443 Cistanche related papers were quantitatively reviewed. The results indicate that 330 institutions from 46 countries have publications in this field. China was the leading country in terms of research importance and number of publication (335 articles). In the past decades, studies on Cistanche have mainly focused on its rich active substances and pharmacological effects. Although the research trend shows that Cistanche has grown from an endangered species to an important industrial plant, its breeding and cultivation continue to be important areas for research. In the future, the application of Cistanche species as functional foods may be a new research trend. In addition, active collaborations among researchers, institutions, and countries are expected.

Melatonin (MT), as a hormone regulating the rhythm of sleep, is widely used in health products. However, illicit and excessive use of MT might cause undesirable effects. Therefore, it is essential to establish highly sensitive and specific rapid methods for MT analysis in health products. In this study, we established indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) and indirect competitive chemiluminescent enzyme immunoassay (ic-CLEIA) for sensitive and selective detection of MT in health products. Under optimal conditions, half-maximum inhibitory concentration (IC₅₀ value) and limit of detection (LOD, IC₁₀ value) for MT by ic-ELISA were 0.25 ng mL⁻¹ and 0.03 ng mL⁻¹ respectively, while the IC₅₀ and LOD of ic-CLEIA were lower at 0.17 ng mL⁻¹ and 0.03 ng mL⁻¹ respectively. Three MT-free Chinese patent medicines were spiked with MT and the recovery rates ranged from 71.89% to 117% (ic-ELISA) and 83.66% to 107.17% (ic-CLEIA). The level of MT in six MT-containing health products was assessed in parallel using the developed methods and HPLC. Both ic-ELISA and ic-CLEIA showed good consistencies (R² = 0.999 and 0.993, respectively) with HPLC, indicating that the two methods developed were sensitive, fast, and reliable for application in MT analysis.

Fibrotic diseases contribute to nearly half of all deaths in industrialized countries, yet effective early detection strategies remain lacking, particularly in low-resource settings. This study aimed to quantify the global burden of fibrosis-related diseases using updated global burden of disease (GBD) 2021 data across 204 countries and territories and establish a cost-effective diagnostic approach targeting vestigial-like family member 3 (VGLL3), a fibrosis-associated transcriptional co-regulator. Our analysis revealed that from 1990 to 2021, fibrosis-related disability-adjusted life years (DALYs) and mortality increased by 16.71% and 4.83%, respectively, with neoplasms and chronic obstructive pulmonary disease (COPD) being the main contributors. We also found a growing burden disproportionately concentrated in low socio-demographic index (SDI) regions. To address the diagnostic gap, we developed a novel immunoassay targeting VGLL3, an intrinsically disordered transcriptional co-regulator implicated in early fibrotic remodeling. The assay demonstrated a detection range of 27.01–2512.36 nM and a limit of detection of 12.55 nM. Immunohistochemical validation in a mouse myocardial infarction model confirmed the antibody’s specificity in fibrotic tissues. This work highlights widening global health disparities in fibrosis burden and introduces a cost-effective, scalable diagnostic strategy for early fibrosis detection, particularly suitable for resource-limited settings.

Liquid-liquid phase separation (LLPS) has emerged as a fundamental mechanism for intracellular organization and dynamic regulation, while nanoscience provi
