Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

ObjectiveTo investigate the mechanism of action of Huangqi Chifengtang (HQCFT) on rats with atherosclerosis (AS) by regulating the gut microbiota and their metabolites. MethodsA rat model of AS was induced through high-fat diet feeding and vitamin D3 injection, and the modeling lasted for 12 weeks. Fifty eight-week-old male SD rats were randomly divided into five groups: A blank group, a model group, a group receiving a low dose of HQCFT at 1.53 g·kg-1 (HQCFT-L group), a group receiving a high dose of HQCFT at 3.06 g·kg-1 (HQCFT-H group), and a group receiving atorvastatin calcium tablets at 1.8 mg·kg-1 (Ato group), with 10 rats in each group. Oral gavage administration started on the day after model establishment, once daily for four weeks. The efficacy of HQCFT was verified using aortic hematoxylin-eosin (HE) staining and determination of lipid levels and hemorrheology. The real-time polymerase chain reaction (Real-time PCR) was used for detecting inflammatory factor levels in the aorta, high-throughput sequencing for analyzing the gut microbiota composition in intestinal contents, targeted metabolomics for detecting short-chain fatty acid (SCFA) levels, and non-targeted metabolomics for identifying metabolomic profiles of intestinal contents. ResultsCompared with that in the blank group, the aortic tissue of rats in the model group showed significant AS lesions, including endothelial damage, inflammatory infiltration, and formation of fibrous plaques and calcified foci. Moreover, serum triacylglycerol (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels were significantly elevated (P<0.05), while high-density lipoprotein cholesterol (HDL-C) levels were significantly reduced (P<0.05). Significant increases were observed in whole blood viscosity, plasma viscosity, and the mRNA expression levels of NOD-like receptor pyrin domain containing 3 (NLRP3), Caspase-1, interleukin (IL)-β, IL-6, and tumor necrosis factor-α (TNF-α) in aortic tissue (P<0.05). Additionally, gut microbiota composition, SCFA levels, and metabolomic profiles were significantly altered. Compared with those in the model group, serum TC, TG, and LDL-C levels, as well as the whole blood viscosity and plasma viscosity, were significantly reduced in all groups treated with HQCFT (P<0.05). Significant decreases were observed in NLRP3 mRNA expression levels in all groups treated with HQCFT, Caspase-1, IL-β, and IL-6 mRNA expression levels in the HQCFT-H group, and TNF-α mRNA expression levels in the HQCFT-L group (P<0.05). HQCFT reversed the increase in the F/B ratio and dialled back the decrease in the relative abundance of Blautia and the increase in that of Desulfovibrio. HQCFT promoted the production of acetic acid, valeric acid, and propionic acid. Non-targeted metabolomics identified 39 differential metabolites, which were mainly enriched in metabolic pathways such as arachidonic acid metabolism and primary bile acid biosynthesis. ConclusionThe mechanism by which HQCFT ameliorates AS injury may be related to the improvement of dyslipidemia and body inflammatory responses by altering gut microbiota composition, promoting SCFA production, and regulating the levels of metabolites in intestinal contents.

Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia (FD), this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes, postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS, whereas local acupoints alone may be more suitable for EPS. Additionally, the study explores the impact of various factors, such as stimulation techniques, needling order, intensity or stimulation parameters, and depth, on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations, local versus distal, affect the treatment outcomes of FD subtypes, providing new insights for clinical acupuncture prescriptions.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Hearing loss is the most prevalent disabling disease. Cochlear implantation(CI) serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system(Favorable, Marginal, Poor). The consensus focuses on common hereditary non-syndromic hearing loss(such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1) and syndromic hereditary hearing loss(such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome), which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

ObjectiveTo analyze the characteristics and trends of injury-related deaths among the registered residents in Yuyao City, Zhejiang Province from 2014 to 2023, and to provide a scientific basis for the formulation of targeted injury prevention and control strategies. MethodsData on injury-related deaths in Yuyao City from January 1, 2014 to December 31, 2023 were collected from the cause-of-death surveillance module of the chronic disease monitoring and management system of Zhejiang Province. Indicators including constituent ratio, crude mortality rate (CMR), standardized mortality rate (SMR), premature death probability, potential years of life lost (PYLL), average years of life lost (AYLL), and potential years of life lost rate (PYLLR) were calculated. The average annual percentage change (AAPC) was used to analyze the trends in injury mortality over the past 10-year period. ResultsFrom 2014 to 2023, a total of 6 625 injury-related deaths were reported in Yuyao City, accounting for 10.65% of all deaths and ranking fourth among all causes. The CMR was 79.34/100 000 and showed an increasing trend (AAPC=4.396%, t=2.875, P=0.021), while the SMR was 38.99/100 000 with no significant trend (AAPC=-0.585%, t=-0.451, P=0.664). The SMR of females (37.74/100 000) was lower than that of males (40.87/100 000) (χ2=12.468, P<0.001). The top 5 causes of injury-related death were falls, traffic accidents, drowning, suicide, and accidental suffocation. Over the 10-year period, the SMRs for traffic accidents, drowning, and suicide showed downward trends (AAPC=-5.381%, t=-3.428, P=0.009; AAPC=-8.061%, t=-6.924, P<0.001; AAPC=-6.919%, t=-4.039, P=0.004, respectively), while the SMRs for falls and accidental suffocation showed no significant trends (AAPC=3.417%, t=1.767, P=0.115; AAPC=2.228%, t=0.803, P=0.445). Injury mortality increased with age for males, females, and the total population (all P<0.05). The leading causes of injury-related death were drowning among residents aged 0‒<15 years, traffic accidents among those aged 15‒<45 and 45‒<65 years, and falls among those aged 65‒<85 and 85‒110 years. The total PYLL due to injury was 58 708.00 person-years, the AYLL was 21.23 years, and the PYLLR was 7.36‰. ConclusionFrom 2014 to 2023, the crude mortality rate due to injuries in Yuyao City remained at a relatively high level, posing a serious threat to residents’ health and well-being. Falls, traffic accidents, drowning, suicide, and accidental suffocation are key targets for injury prevention and control work.
