Colorectal cancer(CRC) is a common malignant tumor worldwide. Due to the treatment intolerance and side effects, CRC rank the top among various cancers regarding the incidence and mortality rates. Therefore, exploring new therapies is of great significance for the treatment of CRC. Aerobic glycolysis(AEG) plays an important role in the microenvironment formation, proliferation, metastasis, and recurrence of CRC and other tumor cells. It has been confirmed that intervening in the AEG pathway can effectively curb CRC. The active ingredients and compound prescriptions of traditional Chinese medicine(TCM) can effectively inhibit the proliferation, metastasis, and drug resistance and regulate the apoptosis of tumor cells by modulating AEG-associated transport proteins [eg, glucose transporters(GLUT)], key enzymes [hexokinase(HK) and phosphofructokinase(PFK)], key genes [hypoxia-inducible factor 1(HIF-1) and oncogene(c-Myc)], and signaling pathways(MET/PI3K/Akt/mTOR). Accordingly, they can treat CRC, reduce the recurrence, and improve the prognosis of CRC. Although AEG plays a key role in the development and progression of CRC, the specific mechanisms are not yet fully understood. Therefore, this article delves into the intrinsic connection of the targets and mechanisms of the AEG pathway with CRC from the perspective of tumor cell glycolysis and explores how active ingredients(oxymatrine, kaempferol, and dioscin) and compound prescriptions(Quxie Capsules, Jiedu Sangen Decoction, and Xianlian Jiedu Prescription) of TCM treat CRC by intervening in the AEG pathway. Additionally, this article explores the shortcomings in the current research, aiming to provide reliable targets and a theoretical basis for treating CRC with TCM.

Recent studies have indicated that the expression of ubiquitin-specific protease 51 (USP51), a novel deubiquitinating enzyme (DUB) that mediates protein degradation as part of the ubiquitin‒proteasome system (UPS), is associated with tumor progression and therapeutic resistance in multiple malignancies. However, the underlying mechanisms and signaling networks involved in USP51-mediated regulation of malignant phenotypes remain largely unknown. The present study provides evidence of USP51's functions as the prominent DUB in chemoresistant triple-negative breast cancer (TNBC) cells. At the molecular level, ectopic expression of USP51 stabilized the 78 kDa Glucose-Regulated Protein (GRP78) protein through deubiquitination, thereby increasing its expression and localization on the cell surface. Furthermore, the upregulation of cell surface GRP78 increased the activity of ATP binding cassette subfamily B member 1 (ABCB1), the main efflux pump of doxorubicin (DOX), ultimately decreasing its accumulation in TNBC cells and promoting the development of drug resistance both in vitro and in vivo. Clinically, we found significant correlations among USP51, GRP78, and ABCB1 expression in TNBC patients with chemoresistance. Elevated USP51, GRP78, and ABCB1 levels were also strongly associated with a poor patient prognosis. Importantly, we revealed an alternative intervention for specific pharmacological targeting of USP51 for TNBC cell chemosensitization. In conclusion, these findings collectively indicate that the USP51/GRP78/ABCB1 network is a key contributor to the malignant progression and chemotherapeutic resistance of TNBC cells, underscoring the pivotal role of USP51 as a novel therapeutic target for cancer management.

High mobility group box 1 (HMGB1), when released extracellularly, plays a pivotal role in the development of spinal cord synapses and exacerbates autoimmune diseases within the central nervous system. In experimental autoimmune encephalomyelitis (EAE), a condition that models multiple sclerosis, the levels of extracellular HMGB1 and interleukin-33 (IL-33) have been found to be inversely correlated. However, the mechanism by which IL-33 deficiency enhances HMGB1 release during EAE remains elusive. Our study elucidates a potential signaling pathway whereby the absence of IL-33 leads to increased binding of P300/CBP-associated factor with HMGB1 in the nuclei of astrocytes, upregulating HMGB1 acetylation and promoting its release from astrocyte nuclei in the spinal cord of EAE mice. Conversely, the addition of IL-33 counteracts the TNF-α-induced increase in HMGB1 and acetylated HMGB1 levels in primary astrocytes. These findings underscore the potential of IL-33-associated signaling pathways as a therapeutic target for EAE treatment.

Objective To investigate the biomechanical characteristics of the mandibular anterior teeth intrusion assisted by buccal mini-implants,so as to provide theoretical guidance for the clinical treatment of deep overbite and other conditions requiring intrusion of the mandibular anterior teeth.Methods A finite element model of implant screws,clear aligners(CAs)and mandibular complex including the mandibular dentition,periodontal ligament(PDL)and alveolar bone was constructed.The model was designed with 0.2 mm intrusion in the mandibular anterior teeth.Seven groups were set:without traction,30 g,50 g,100 g,150 g,200 g,and 250 g force groups.The stress and displacement of the teeth as well as the related stress distributions of PDL and CAs in each group after loading were analyzed.Results Without traction and under different traction forces,the mandibular anterior teeth tended to be tipped and intruded.With the increase of traction force,the increasing trend was manifested in the vertical displacement and labial displacement of the mandibular anterior teeth.When the traction force reached 200 g,the vertical displacement showed a significant increase,the subsequent increase then showed a tendency to flatten.The ratio of the labial tipping displacement to the intrusive displacement of the mandibular anterior teeth showed a decreasing trend with the increase of traction force.Within a reasonable force range,increasing traction force led to greater bodily intrusion of the anterior teeth.When the traction force was less than 150 g,the mandibular posterior teeth exhibited a tendency of extrusion.When the traction force of more than 150 g was applied,it showed a tendency of intrusion.The PDL stress was concentrated on the labial and cervical surface of the anterior teeth.Conclusions Intrusion efficiency of the mandibular anterior teeth has been effectively improved with CAs assisted by buccal mini-implants.Moreover,the traction force of the mini-implants has a significant impact on the movement of the mandibular anterior teeth.Based on a comprehensive analysis of factors such as the displacement trend of the mandibular dentition and the PDL stress,the optimal force value for buccal traction of the mini-implants to intrude the mandibular anterior teeth can be selected as 150-200 g force.

In recent years， as the incidence of ulcerative colitis （UC） is growing， intestinal mucosal injury has garnered increasing attention， and it is characterized by high recurrence， risk of inflammation-cancer transformation， and difficulty in repair. Intestinal mucosal injury in UC is centered on persistent inflammation and barrier dysfunction， with its pathological mechanisms involving endoplasmic reticulum stress （ERS）-mediated changes such as abnormal apoptosis， abnormal autophagy， and inflammatory responses. ERS induces apoptosis of intestinal epithelial cells， disrupts tight junction proteins， and exacerbates inflammatory responses through pathways such as protein kinase R-like endoplasmic reticulum kinase （PERK）， inositol-requiring enzyme 1 alpha （IRE1α）， and activating transcription factor 6 （ATF6）， ultimately causing intestinal mucosal injury. Traditional Chinese medicine （TCM） has a long history of research on UC. The theory of sores depending on spleen-earth holds that spleen deficiency is the fundamental cause of UC， while pathological products such as dampness-turbidity and blood stasis are the secondary manifestations. Dysfunction of the spleen-earth leads to insufficient production and transformation of Qi and blood， malnutrition of the intestinal mucosa， and invasion of external pathogens. In the active phase of UC， spleen deficiency is often accompanied by excessive pathogenic factors such as dampness-heat and heat-toxin， leading to acute intestinal mucosal damage. In the remission phase， however， it is mainly characterized by spleen deficiency and healthy Qi deficiency， accompanied by residual pathogens， resulting in weak intestinal mucosal repair. Studies have shown that the endoplasmic reticulum， as a key site for protein synthesis and folding， has functions highly similar to the TCM concept of the spleen governing transportation and transformation. From a TCM perspective， the endoplasmic reticulum can be regarded as the carrier of spleen transportation， and ERS is a microcosmic manifestation of spleen dysfunction， leading to intestinal mucosal injury. ERS impairs the structure and function of the endoplasmic reticulum， induces the generation of abnormal Qi， and triggers pathological changes， making inflammation difficult to be reduced and causing the aggravation of ERS， forming a vicious cycle of spleen deficiency-pathological products-intestinal injury. TCM has unique advantages in regulating ERS to prevent and treat intestinal mucosal injury. According to the theory of sores depending on spleen-earth and the modern medical understanding of ERS， this paper delves into the TCM and Western medicine pathogenesis of intestinal mucosal injury in UC. Furthermore， this paper discusses the roles of TCM active components and compound formulas in reducing intestinal mucosal injury in UC by regulating ERS under the guidance of the treatment principles of invigorating the spleen and replenishing Qi as the key and dispelling dampness and removing blood stasis as the supplementation， aiming to provide new ideas and methods for the prevention and treatment of UC.

This study employed the "disease-medicine-dose" pattern to mine the medication rules of traditional Chinese medicine(TCM) prescriptions containing Astragali Radix in ancient Chinese medical books, aiming to provide a scientific basis for the clinical application of Astragali Radix and the development of new medicines. The TCM prescriptions containing Astragali Radix were retrieved from databases such as Chinese Medical Dictionary and imported into Excel 2020 to construct the prescription library. Statical analysis were performed for the prescriptions regarding the indications, syndromes, medicine use frequency, herb effects, nature and taste, meridian tropism, dosage forms, and dose. SPSS statistics 26.0 and IBM SPSS Modeler 18.0 were used for association rules analysis and cluster analysis. A total of 2 297 prescriptions containing Astragali Radix were collected, involving 233 indications, among which sore and ulcer, consumptive disease, sweating disorder, and apoplexy had high frequency(>25), and their syndromes were mainly Qi and blood deficiency, Qi and blood deficiency, Yin and Yang deficiency, and Qi deficiency and collateral obstruction, respectively. In the prescriptions, 98 medicines were used with the frequency >25 and they mainly included Qi-tonifying medicines and blood-tonifying medicines. Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Ginseng Radix et Rhizoma, Atractylodis Macrocephalae Rhizoma, and Citri Reticulatae Pericarpium were frequently used. The medicines with high frequency mainly have warm or cold nature, and sweet, pungent, or bitter taste, with tropism to spleen, lung, heart, liver, and kidney meridians. In the treatment of sore and ulcer, Astragali Radix was mainly used with the dose of 3.73 g and combined with Glycyrrhizae Radix et Rhizoma to promote granulation and heal up sores. In the treatment of consumptive disease, Astragali Radix was mainly used with the dose of 37.30 g and combined with Ginseng Radix et Rhizoma to tonify deficiency and replenish Qi. In the treatment of sweating disorder, Astragali Radix was mainly used with the dose of 3.73 g and combined with Glycyrrhizae Radix et Rhizoma to consolidate exterior and stop sweating. In the treatment of apoplexy, Astragali Radix was mainly used with the dose of 7.46 g and combined with Glycyrrhizae Radix et Rhizoma to dispell wind and stop convulsions. Astragali Radix can be used in the treatment of multiple system diseases, with the effects of tonifying Qi and ascending Yang, consolidating exterior and stopping sweating, and expressing toxin and promoting granulation. According to the manifestations of different diseases, when combined with other medicines, Astragali Radix was endowed with the effects of promoting granulation and healing up sores, tonifying deficiency and Qi, consolidating exterior and stopping sweating, and dispelling wind and replenishing Qi. The findings provide a theoretical reference and a scientific basis for the clinical application of Astragali Radix and the development of new medicines.

OBJECTIVE: Gastric cancer (GC) is one of the most common malignancies seen in clinic and requires novel treatment options. Morin is a natural flavonoid extracted from the flower stalk of a highly valuable medicinal plant Prunella vulgaris L., which exhibits an anti-cancer effect in multiple types of tumors. However, the therapeutic effect and underlying mechanism of morin in treating GC remains elusive. The study aims to explore the therapeutic effect and underlying molecular mechanisms of morin in GC. METHODS: For in vitro experiments, the proliferation inhibition of morin was measured by cell counting kit-8 assay and colony formation assay in human GC cell line MKN45, human gastric adenocarcinoma cell line AGS, and human gastric epithelial cell line GES-1; for apoptosis analysis, microscopic photography, Western blotting, ubiquitination analysis, quantitative polymerase chain reaction analysis, flow cytometry, and RNA interference technology were employed. For in vivo studies, immunohistochemistry, biomedical analysis, and Western blotting were used to assess the efficacy and safety of morin in a xenograft mouse model of GC. RESULTS: Morin significantly inhibited the proliferation of GC cells MKN45 and AGS in a dose- and time-dependent manner, but did not inhibit human gastric epithelial cells GES-1. Only the caspase inhibitor Z-VAD-FMK was able to significantly reverse the inhibition of proliferation by morin in both GC cells, suggesting that apoptosis was the main type of cell death during the treatment. Morin induced intrinsic apoptosis in a dose-dependent manner in GC cells, which mainly relied on B cell leukemia/lymphoma 2 (BCL-2) associated agonist of cell death (BAD) but not phorbol-12-myristate-13-acetate-induced protein 1. The upregulation of BAD by morin was due to blocking the ubiquitination degradation of BAD, rather than the transcription regulation and the phosphorylation of BAD. Furthermore, the combination of morin and BCL-2 inhibitor navitoclax (also known as ABT-737) produced a synergistic inhibitory effect in GC cells through amplifying apoptotic signals. In addition, morin treatment significantly suppressed the growth of GC in vivo by upregulating BAD and the subsequent activation of its downstream apoptosis pathway. CONCLUSION Morin suppressed GC by inducing apoptosis, which was mainly due to blocking the ubiquitination-based degradation of the pro-apoptotic protein BAD. The combination of morin and the BCL-2 inhibitor ABT-737 synergistically amplified apoptotic signals in GC cells, which may overcome the drug resistance of the BCL-2 inhibitor. These findings indicated that morin was a potent and promising agent for GC treatment.

Objective:To examine the near-complete genomic analysis of norovirus (NoV) subtype GⅡ.17 [P17] outbreaks in Beijing Chaoyang District from 2014 to 2024.Methods:Data and specimens related to outbreaks of the NoV aggregation in Beijing′s Chaoyang District from 2014 to 2024 were collected. The NoV was identified using real-time fluorescence reverse transcription polymerase chain reaction (RT-PCR). Specimens with positive nucleic acid were amplified by standard PCR, whole genome sequencing and evolutionary analysis. Amino acid site variations were compared.Results:In Chaoyang District, from 2014 to 2024, a total of 637 aggregated outbreaks caused by the NoV infection were reported, of which 584 were successfully typed. The epidemic caused by the GⅡ.17 [P17] subtype accounted for 8.79% (56/637), which was the dominant epidemic gene subtype in 2014-2015, sporadic in 2016-2019, reappeared in 2022, and significantly increased in 2024 (27.27%, 24/88). Outbreaks caused by the GⅡ.17 [P17] subtype occurred mainly from October to December, with the main sites of occurrence in primary schools and kindergartens. This study yielded 53 near-complete genome sequences of the GⅡ.17 [P17] subtype from 46 incidents in Chaoyang District. The GⅡ.17 [P17] subtype sequences of Chaoyang District from 2014 to 2024 were segmented into three subgroups on the evolutionary tree, with sequences from 2014 to 2019, 2022 to April 2024, and May to December 2024 clustered into the d, e, and b subgroups, respectively. In the VP1 region′s P2 area, particularly at the HBGA binding site, subgroups b and e exhibited mutations in 22 and two sites, while subgroups b and e showed mutations in four and one sites, predominantly in the RdRp region.Conclusion:The outbreak caused by the NoV GⅡ.17 [P17] subtype in Chaoyang District from 2014 to 2024 continues, with a significant increase in 2024, and it becomes the dominant gene subtype from October to December. The sequence formation of the NoV GⅡ.17 [P17] subtype in Chaoyang District from January to April 2022 and from May to December 2024 shows two different evolutions, with specific mutation sites, requiring continuous monitoring of the NoV GⅡ.17 [P17] subtype.

Objective To investigate the status and influencing factors of psychological distress associated with weight loss among young and middle-aged adults with obesity,so as to provide a theoretical basis for developing personalized interventions and improving psychological well-being.Methods A convenience sampling method was used to select young and middle-aged obese patients who visited the weight management clinic of a Grade A tertiary hospital in Jiangxi Province from October 2024 to May 2025.Data were collected using a general information questionnaire,the distress thermometer,the perceived social support scale,the brief illness perception questionnaire,and the simplified coping style questionnaire.Binary logistic regression was applied to identify factors influencing psychological distress.Results A total of 204 valid questionnaires were collected.The detection rate of significant psychological distress was 58.82%(120 cases).Regarding weight loss methods,32.84%of participants opted for medication.The top five issues reported on the psychological distress problem list were:appearance/body image,work/studies,lack of time/energy to care for elderly parents or children,bathing/dressing,and relationship with a partner.Binary logistic regression indicated that age,body mass index,waist circumference,history of chronic disease,perceived social support,illness perception,and negative coping style were significant influencing factors of psychological distress(P﹤0.05).Conclusions The rate of significant psychological distress is relatively high among young and middle-aged obese patients and is influenced by multiple factors.Medical staff may develop personalized interventions based on these factors to reduce the incidence of psychological distress.
