OBJECTIVE: To reach consensus on the diagnostic criteria of syndrome of dampness obstruction in idiopathic membranous nephropathy(IMN) patients by literature research and expert investigation(interviews and a Delphi method). METHODS: Our study was consistent with T/CACM 1336-2020. We searched the monographs and references published in the past 40 years(1983-2022), and established the diagnostic criteria pool of waterdampness syndrome and dampness-turbidity syndrome in Traditional Chinese Medicine(TCM) based on literature by using frequency statistics and correlation analysis. Expert investigation(interview method and two rounds of Delphi method) was used to form the diagnostic criteria of water-dampness syndrome and dampnessturbidity syndrome of idiopathic membranous nephropathy. Clinical diagnostic test research was carried out, and compared with “Diagnostic Criteria for dampness syndrome”(T/CACM 1454-2023) to evaluate the authenticity, reliability and clinical application value of the standard. RESULTS: A total of 122 relevant guides, standards, monographs and documents were included through searching books and Chinese databases. Four experts were interviewed and two rounds of delphi method(75 experts nationwide) were carried out. The experts' opinions are relatively concentrated and the differences are small. Based on the weight of each index, the diagnostic criteria indexes of water-dampness syndrome and dampness-turbidity syndrome were selected. After discussion by the core group members, the diagnostic model of "necessary symptoms and optional symptoms" was established, and the final diagnostic criteria of waterdampness syndrome and dampness-turbidity syndrome were established. One hundred and ninety-one inpatients and outpatients of Guangdong Provincial Hospital of Chinese Medicine from January 2021 to February 2023 were included in Diagnostic test study. There was no statistical difference in gender, age and course of disease(P > 0.05). The sensitivity and s

TRIM66-HP1γ remodels the chromatin through phase separation

生物物理学报（英文） 2025年第1期11卷 18-33页

Chromatin contains not only heterochromatin (HC) and euchromatins (EC) but also facultative heterochromatin (fHC), which experience the dynamic remodeling between HCs and ECs by different regulators. The regulation of fHCs involves lots of different cell functions, like genomic stability and gene transcription. Heterochromatin protein 1 (HP1) recognizes methylated H3K9 and reshapes the chromatin into the fHCs through liquid–liquid phase separation (LLPS). Among the three members of the HP1 family, HP1α can condensate by itself and HP1β forms granules with the help of TRIM28, while the HP1γ cannot phase separation alone either and the coordinator is still unclear. So, in this study, we investigated the molecular mechanism of how HP1γ interacts with TRIM66 through PxVxL motif. Based on that, we examined the key regions that controlled the TRIM66-HP1γ co-phase separation behaviors both in vitro and in vivo. Furthermore, we proved that the liquid granules of TRIM66-HP1γ and chromatin highly correlated with H3K9me3 sites, which indicated the relationship with DNA damage response. Finally, combined with our previous study, we proposed the system for how TRIM66 remodeled the chromatin into compressed fHC through the TRIM66-HP1γ-H3K9me3 axis with liquid–liquid phase separation.

Acceptor concentration dependent Fo?rster resonance energy transfer in nanocrystal-molecule complexes revealed by spectral analysis

引用

Optoelectronics Letters 2025年

作者： Rongxin zhang Zixiang ZHOU Lei WANG Xin zhang Ying liang Guijie liang Hubei Key Laboratory of Low Dimensional Optoelectronic Materials and Devices， Hubei University of Arts and Science

A nanocrystal-molecule complex composed of CdSe donor and Rhodamine B (RhB) acceptor is prepared to investigate the effect of accepter-donor ratio on the Fo?rster resonance energy transfer (FRET) process. To highlight the FRET process， the energy level alignment between CdSe and RhB is purposefully designed and CdSe nanocrystal is coated with a wide band-gap ZnS shell. The carrier dynamics is observed via combined spectral analysis. The results reveal clear FRET process between the CdSe donor and RhB acceptor. The FRET is enhanced by increasing RhB/CdSe ratio and a gradual saturation will be present at high RhB concentration.

Spinal cord injuries lead to significant loss of motor, sensory, and autonomic functions, presenting major challenges in neural regeneration. Achieving effective therapeutic concentrations at injury sites has been a slow process, partly due to the difficulty of delivering drugs effectively. Nanoparticles, with their targeted delivery capabilities, biocompatibility, and enhanced bioavailability over conventional drugs, are garnering attention for spinal cord injury treatment. This review explores the current mechanisms and shortcomings of existing treatments, highlighting the benefits and progress of nanoparticle-based approaches. We detail nanoparticle delivery methods for spinal cord injury, including local and intravenous injections, oral delivery, and biomaterial-assisted implantation, alongside strategies such as drug loading and surface modification. The discussion extends to how nanoparticles aid in reducing oxidative stress, dampening inflammation, fostering neural regeneration, and promoting angiogenesis. We summarize the use of various types of nanoparticles for treating spinal cord injuries, including metallic, polymeric, protein-based, inorganic non-metallic, and lipid nanoparticles. We also discuss the challenges faced, such as biosafety, effectiveness in humans, precise dosage control, standardization of production and characterization, immune responses, and targeted delivery in vivo. Additionally, we explore future directions, such as improving biosafety, standardizing manufacturing and characterization processes, and advancing human trials. Nanoparticles have shown considerable progress in targeted delivery and enhancing treatment efficacy for spinal cord injuries, presenting significant potential for clinical use and drug development.
