ObjectiveTaking Aurantii Fructus Immaturus juice（AFI）-processed Atractylodis Macrocephalae Rhizoma（AMR） as an example， this study aims to systematically compare the volatile and non-volatile components of AMR and its processed products， investigate the key differential components， evaluate their anti-inflammatory activities， and elucidate the synergistic mechanism of processing. MethodsThe chemical compositions of volatile and non-volatile components in AMR and AFI-processed AMR were systematically characterized using gas chromatography-mass spectrometry（GC-MS） and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）， with relative mass fractions and response values determined separately. Volatile components were identified through searches in the National Institute of Standards and Technology（NIST）17 database， comparison with retention index（RI） and fragmentation pattern matching. Non-volatile components were identified by searching Waters Traditional Chinese Medicine （TCM） spectral library， in conjunction with PubChem and MassBank， characteristic fragmentation patterns and response values were also used to support identification. Differential components were screened using principal component analysis（PCA）， orthogonal partial least squares-discriminant analysis（OPLS-DA）， with variable importance in the projection（VIP） value >1. Components with high log₂fold change（FC） among major differential groups were selected as those exhibiting significant changes before and after processing. The anti-inflammatory activity of the differential compounds was evaluated by assessing their effects on nitric oxide（NO） production in a lipopolysaccharide（LPS）-induced RAW264.7 macrophage model. Enzyme-linked immunosorbent assay（ELISA） was used to detect the effects of the differential components on tumor necrosis factor（TNF）-α， interleukin（IL）-1β， IL-6， and monocyte chemotactic protein（MCP）-1 levels， and immunofluorescence（IF） was employed to assess their effects on nuclear transcription factor（NF）-κB p65 translocation， thereby elucidating the underlying molecular mechanisms. ResultsA total of 36 compounds were identified in the volatile components of AMR and AFI-processed AMR， among which， sesquiterpenes and monoterpenes were significantly increased after processing. In the non-volatile components， 36 compounds were identified， and the main differential components were flavonoids， sesquiterpenoids， and triterpenoids. Flavonoids were the primary differential components distinguishing AMR from its processed products， representing compounds directly introduced during processing. Five compounds， including atractylenolide Ⅲ， tangeritin， nobiletin， hesperidin and narirutin， were selected as representatives of three classes based on their most prominent differential expression among different compound types for subsequent anti-inflammatory activity studies. The results showed that 100 μmol·L^-1 tangerine and narirutin could significantly inhibit LPS-induced NO production（P<0.01） in a concentration-dependent manner. Tangeritin was able to significantly inhibit the levels of TNF-α and MCP-1 secreted by RAW264.7（P<0.05）， while narirutin significantly inhibited the levels of TNF-α， IL-1β， MCP-1 and IL-6（P<0.01）. IF revealed that both tangeritin and narirutin significantly blocked the translocation of NF-κB p65 from the cytoplasm to the nucleus. ConclusionAFI-processed AMR significantly alters the chemical composition profile of AMR， and the newly introduced flavonoid components during processing may be key to its enhanced anti-inflammatory effects.

The linear ubiquitin chain assembly complex (LUBAC), composed of heme-oxidized IRP2 ubiquitin ligase 1-interacting protein (HOIP), haem-oxidized IRP2 ubiquitin ligase-1(HOIL-1), and SHANK-associated RBCK1 homology-domain-interacting protein (SHARPIN), and its specific deubiquitinating enzyme OTULIN, regulates the dynamic balance of Met1-linked linear ubiquitination and maintains ubiquitin signaling homeostasis. Their precise interaction plays a central role in the regulation of nuclear factor-κB (NF-κB) and type I interferon signaling, inflammatory response, and cell survival and death. Dysregulation of the LUBAC-OTULIN axis can lead to aberrant immune and inflammatory signaling, immunodeficiency, and dysregulation of receptor-interacting protein kinase 1-mediated apoptosis or necroptosis. Genetic defects in OTULIN and LUBAC are associated with rare autoinflammatory diseases such as OTULIN-related autoinflammatory syndrome (ORAS) and HOIP/HOIL-1/SHARPIN deficiency, respectively, with complex clinical phenotypes and gene dose correlation. Current treatments primarily rely on glucocorticoids and tumor necrosis factor inhibitors, and hematopoietic stem cell transplantation has shown potential curative value in some patients with severe ORAS. This review summarizes the molecular composition, interaction mechanisms, and pathogenic roles of the LUBAC-OTULIN axis in rare autoinflammatory diseases, providing reference for the development of targeted therapeutic strategies.

Methods: In May 2025, 77 experts in the fields of health and education from 11 cities in Zhejiang Province were selected by convenient sampling method to participate in the first round of expert consultation. In June, 2025, snowball sampling was used to expand to 194 experts for the second round of consultation, and it was convenient to select 21 students from primary schools to high schools in Zhejiang Province and 29 parents to empower the evaluation criteria. It applied the Child Health and Nutrition Research Initiative (CHNRI) method in a structured process, which encompassed the definition of the research field, generation of research ideas, scoring, and quantitative ranking of priorities. Research ideas were evaluated against 6 predefined criteria: effectiveness, safety, answerability, feasibility, sustainability, and scientific significance. Results: After 2 rounds of structured consultations, 81 research ideas on physical and mental comorbidity among children and adolescents were established and classified into 7 subthemes: epidemiological characteristics and influencing factors, optimization of primary service systems and policies, comprehensive intervention strategies for physical and mental comorbidity, biological mechanisms and clinical research, the impact of education and environment on physical and mental health, special populations and social support, and digital and technology driven disease prevention and intervention. The top 10 research priorities primarily centered on the subdomain of "epidemiological characteristics and influencing factors" (5 items). The top 3 research priorities were "the association between outdoor activity duration and the incidence of common diseases (including mental disorders) among children and adolescents" "the impact of outdoor activity duration on the physical and mental health of adolescents" "comprehensive intervention strategies for myopia, obesity, and their comorbidities among children and adolescents". Conclusion The framework of priority issues in the field of psychosomatic comorbidity of children and adolescents in Zhejiang Province based on CHNRI method provides a reference for optimizing the allocation of provincial research resources.

BACKGROUND:Marine traditional Chinese medicine offers a potentially effective and less adverse treatment for osteoporosis.OBJECTIVE:To explore the pharmacological regulations and procedures of traditional Chinese medicine in treating osteoporosis through data mining and network pharmacology techniques.METHODS:Data mining and network pharmacology methods were used to study the medication pattern and mechanism of marine Chinese medicine patented prescriptions approved by China National Intellectual Property Administration for the treatment of osteoporosis,and special attention was paid to the core Chinese medicine constituents of these prescriptions.The core constituents of the compound drug group composed of oyster-Dipsacus asper-epimedium were comprehensively identified and analyzed by using ultra-high-performance liquid chromatography tandem mass spectrometry.RESULTS AND CONCLUSION:(1)We collected 381 authorized compound patents for the treatment of osteoporosis from the database inception to April 1,2024.Among these,48 patent groups utilized marine traditional Chinese medicine.These prescriptions contained 183 Chinese herbal medicines,of which 13 marine traditional Chinese medicines were used 574 times in total,and the number of flavors used in a single patented formula ranged from 2 to 41.(2)Oyster was the most frequently used marine ingredient,while Dipsacus asper,epimedium,Rehmannia glutinosa,Eucommia ulmoides Oliv.were the most frequent non-marine components.Association rule analysis identified oyster,Dipsacus asper,and epimedium as the core drug group.Network pharmacology analysis revealed that the core targets of this group for the treatment of osteoporosis included ALB,AKT1,TP53,PPARG,and SRC.Sitosterol,liquiritigenin,japonine,luteolin,and kaempferol were identified as the core components within the marine traditional Chinese medicine prescriptions.(3)The GO and KEGFG enrichment analyses suggested a potential association between the mechanism of the core drug group and the rap1/mapk signaling pathway in the treatment of osteoporosis.(4)The molecular docking verified the beneficial interactions between core components and core targets.(5)The ultra-high-performance liquid chromatography tandem mass spectrometry analysis of the compound medicine confirmed the presence of luteolin,sitosterol,kaempferol,and other components,aligning with the drug components identified by network pharmacology.Quantitative analysis indicated that flavonoids,terpenes,and alkaloids constituted a significant proportion of the compound medicine's components.

OBJECTIVE: To investigate the efficacy and safety of combination regimen containing daratumumab in multiple myeloma (MM) patients. METHODS: The clinical data of 14 newly diagnosed MM patients and 58 relapsed refractory MM patients treated with combination regimen containing daratumumab from November 2020 to March 2023 in the First Affiliated Hospital of Nanchang University were retrospectively analyzed. The efficacy and safety of combination regimen were analyzed. RESULTS: The median age of the 72 patients was 62 (38-78) years, including 35 males and 37 females. The overall response rate (ORR) of patients receiving first-line, second-line, and third-line or above treatment was 92.9% (13/14), 68.2% (30/44), and 42.9% (6/14), respectively. The median progression-free survival (PFS) was not reached, 15.4 months, and 9.7 months in three groups, respectively (all P <0.05), while the median overall survival (OS) was all not reached. Among relapsed refractory patients, the ORR of those treated with DVd, DPd and DRd regimen was 50.0% (12/24), 40.0% (4/10) and 100% (10/10), the median PFS was 2.8 months, 10.3 months and not reached, and the median OS was 15.4 months, not reached and not reached, respectively. Furthermore, the PFS and OS in the DRd group were superior to those in the other two groups (all P <0.05). Cox univariate and multivariate analysis showed that lactate dehydrogenase (LDH) ≥250 U/L and extramedullary disease were independent adverse prognostic factors for PFS, and LDH ≥250 U/L was also an independent adverse prognostic factor for OS. Hematologic adverse reactions were mainly lymphopenia (87.5%) and thrombocytopenia (52.8%), while non-hematologic adverse reactions were mainly infusion-related reactions (19.4%) and infections (11.1%). CONCLUSIONS The combination regimens containing daratumumab can be used as first-line treatment for patients with newly diagnosed MM. In patients with relapsed refractory MM, early use of regimens containing daratumumab may improve treatment response rate and prolong PFS. The DRd regimen has better therapeutic response and survival advantages. LDH is an independent prognostic factor affecting PFS and OS in MM patients.

OBJECTIVE: To investigate possible associations between physical function assessment scales, such as Short Physical Performance Battery (SPPB) and Berg Balance Scale (BBS), with all-cause mortality in acute decompensated heart failure (ADHF) patients. METHODS: A total of 108 ADHF patients were analyzed from October 2020 to October 2022, and followed up to May 2023. The association between baseline clinical characteristics and all-cause mortality was analyzed by univariate Cox regression analysis, while for SPPB and BBS, univariate Cox regression analysis was followed by receiver operating characteristic curves, in which the area under the curve represented their predictive accuracy for all-cause mortality. Incremental predictive values for both physical function assessments were measured by calculating net reclassification index and integrated discrimination improvement scores. Optimal cut-off value for BBS was then identified using restricted cubic spline plots, and survival differences below and above that cut-off were compared using Kaplan-Meier survival curves and the log-rank test. The clinical utility of BBS was measured using decision curve analysis. RESULTS: For baseline characteristics, age, female, blood urea nitrogen, as well as statins, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, or angiotensin receptor-neprilysin inhibitors, were predictive for all-cause mortality for ADHF patients. With respect to SPPB and BBS, higher scores were associated with lower all-cause mortality rates for both assessments; similar area under the curves were measured for both (0.774 for SPPB and 0.776 for BBS). Furthermore, BBS ≤ 36.5 was associated with significantly higher mortality, which was still applicable even adjusting for confounding factors; BBS was also found to have great clinical utility under decision curve analysis. CONCLUSIONS BBS or SPPB could be used as tools to assess physical function in ageing ADHF patients, as well as prognosticate on all-cause mortality. Moreover, prioritizing the improvement of balance capabilities of ADHF patients in cardiac rehabilitation regimens could aid in lowering mortality risk.

BACKGROUND: The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

Objective:To study the alternation of plasma ghrelin in patients with acute pancreatitis (AP) and to evaluate the efficacy of gastric slow wave analysis in predicting the severity of AP.Methods:Clinical data and blood samples of 129 patients with AP and 16 individuals for normal physical examination in the Department of Gastroenterology, Jiangnan University Affiliated Central Hospital (Wuxi No.2 People's Hospital) from September 2018 to August 2024 were prospectively collected. Individuals with normal physical examinations were included in the normal control group, including 9 males and 7 females, aged (50.9±14.2) years. The finally enrolled 125 patients with AP included 82 males and 43 females, aged (49.5±15.6) years, which were grouped according to disease severity. Mild AP (MAP) was included in the MAP group ( n=84), while moderate to severe and severe acute AP were included in the non-MAP group ( n=41). The surface gastrogram of all AP patients was detected on the 2nd and 4th day after admission. The slow waves of gastric electricity were recorded, and gastric growth hormone-releasing hormone, C-reactive protein (CRP), etc. were detected simultaneously. Univariate and multivariate logistic regression analyses were conducted to analyze the influencing factors of AP severity (MAP or non-MAP). Receiver operating characteristic (ROC) curve was used to evaluate the indicators in predicting the severity of AP. Results:The levels of gastric growth hormone-releasing hormone in both the non-MAP group and MAP group on the 2nd and 4th day after admission were lower than those in normal control group (all P<0.05). The percentages of normal gastric electrical slow waves in the first and fourth leads, the mean percentages of normal gastric electrical slow waves in the four leads, and the main frequency on the 2nd day of admission in the non-MAP group were lower than those in the normal control group, and the main power and C-reactive protein were higher than those in the MAP group, the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed the percentage of normal gastric electrical slow wave in the first lead on the 2nd day of admission ( OR=0.914, 95% CI: 0.869-0.961, P=0.001) and CRP ( OR=1.008, 95% CI: 1.002-1.013, P=0.012) were the influencing factors of the severity of AP. The area under the ROC curve of the percentage of normal gastric electrical slow wave in the first lead on the 2nd day of admission in predicting the severity of AP was 0.705, with a sensitivity of 97.6% and a specificity of 35.7%. Conclusion:The plasma gastric growth hormone-releasing hormone in patients with AP decreases in the early stage. The low percentage of normal slow waves in the first lead of gastric electrocardiogram on the 2nd day of admission is a risk factor for the severity of AP and can be used for the early prediction of the severity.

Objective To identify the enhancer profile marked by histone H3K27ac modification in high-grade intraepithelial neoplasia(HGIN)in order to reveal the novel regulatory mechanism of HGIN pathogensis.Methods Gastric tissue samples were collected from Department of Gastroenterology of Army Medical Center of PLA between June 2022 and June 2023,including 14 normal gastric tissues(Nor group),31 HGIN tissues(HGIN group)and 17 gastric cancer tissues(GC group).Cleavage under targets and tagmentation(CUT&Tag)technique was employed to capture enhancer regions modified by histone H3K27ac.Multi-omics analysis was performed to identify HGIN-specific active enhancers and their potentially regulated genes.Immunohistochemical profiling was performed to assess differential expression of the gene of interest across clinically stratified specimens,combined with CRISPR-dCas9-mediated ablation of active enhancers to monitor the gene of interest transcriptional dynamics and validate enhancer-mediated regulatory mechanisms.Results Epigenomic sequencing obtained the data with excellent quality,and indicated that obvious remodeling was observed in H3K27ac enhancers in HGIN and GC groups(P<0.05),though no significant difference in the genome-wide distribution of H3K27ac modification among the 3 groups.Combining transcriptome data revealed that enhancer remodeling may up-regulate the expression of the proliferation-related target gene,CD24,in the HGIN tissue;while,inhibiting enhancer activity can notably reduce CD24 expression level(P<0.05).Immunohistochemical assay displayed a positive correlation between the expression levels of CD24 and Ki-67(P<0.001).Conclusion The remodeling of H3K27ac enhancer represents a significant epigenetic feature of the transformation from normal condition to HGIN.Remodeling of H3K27ac enhancer up-regulates CD24,which may facilitate the abnormal proliferation of gastric epithelial cells.

Objective To investigate whether O6-methylguanine-DNA methyltransferase(MGMT)interference combined with temozolomide(TMZ)could enhance the therapeutic effect of temozolomide on human drug-resistant melanoma cells A375/TMZ.Methods A375/TMZ cells were randomly divided into 4 groups,control group(normal culture),MGMTsiRNA group(200 nmol·L-1 MGMTsiRNA),experimental group(1 600 μmol·L-1 TMZ)and combined group(transfection of MGMTsiRNA followed by addition of 1 600 μmol·L-1 TMZ).After 24 h of culture,the proliferation of cells in each group was analyzed by cell counting kit-8 method.Western blotting was used to detect the expression levels of poly ADP-ribose polymerase(PARP),cleaved PARP(cleaved-PARP),DNA-dependent protein kinase catalytic subunit(DNA-PKcs)and nuclear factor kappa-B(NF-κB)proteins in the cells.The expression and distribution of NF-κB proteins in the cells were detected by immunofluorescence.Results Cell inhibition rates of control,MGMTsiRNA,experimental and combined groups were 0,(3.45±1.53)％,(51.24±2.73)％and(70.69±4.48)％;the relative expression levels of PARP protein were 0.45±0.08,0.47±0.06,0.33±0.04,0.14±0.03;the relative expression levels of the cleaved-PARP protein were 0.01±0.02、0.01±0.01、0.18±0.03 and 0.36±0.04;the relative expression levels of DNA-PKcs protein were 0.09±0.03,0.07±0.02,0.32±0.02 and 0.39±0.04;the relative expression levels of NF-κB protein were 0.35±0.04,0.36±0.05,0.20±0.02 and 0.15±0.02.Compared with experimental group or control group,the differences of above indexes were all statistically significant(all P＜0.05).Immunofluorescence analysis showed that the average fluorescence intensity of NF-κB in control group,MGMTsiRNA group,experimental group and combined group were(5.26±1.05)％,(7.58±1.18)％,(10.56±1.99)％and(15.47±2.61)％;and compared with the cells in control group and MGMTsiRNA group,combined group showed NF-κB was significantly increased in the nucleus of tumor cells,and the difference was statistically significant(all P＜0.01).Conclusion MGMTsiRNA combined with TMZ further promotes proliferation inhibition and apoptosis of drug-resistant melanoma A375/TMZ cells by TMZ.
