ObjectiveTo identify the pathogen species responsible for the wilt disease of Tetradium ruticarpum in Chongqing， investigate there biological characteristics， and screen effective fungicides， so as to provide a theoretical basis for disease control in production. MethodsThe pathogen was isolated via the tissue culture method. Pathogenicity was verified according to Koch's postulates. The pathogen was identified based on morphological characteristics and multi-gene phylogenetic analysis. The mycelial growth rate method was used for biological characterization of the pathogen and fungicide screening. ResultsThe pathogen colonies were nearly circular with irregular edges， white， short， velvety aerial hyphae， and pale purple undersides. Macroconidia were colorless， sickle-shaped， with 3-5 septa， while microconidia were transparent， elliptical， aseptate or with 1-2 septa. Multi-gene phylogenetic analysis showed that the pathogen clustered in the same clade as Fusarium fujikuroi with 100% support， which， combined with morphological characteristics， identified the pathogen causing wilt of T. ruticarpum in Chongqing as F. fujikuroi. The optimal conditions for the mycelial growth of F. fujikuroi were mung bean agar （MBA） with glucose as the carbon source， beef extract and yeast powder as nitrogen sources， 28 ℃， pH 7.0， and alternating light/dark conditions. The optimal conditions for sporulation were potato dextrose agar （PDA） with glucose as the carbon source， beef extract as the nitrogen source， 28 ℃， pH 7.0， and complete darkness. Among chemical fungicides， phenazine-1-carboxylic acid exhibited the strongest inhibitory effect on F. fujikuroi. Shenqinmycin and tetramycin were the most effective bio-fungicides. ConclusionThis study is the first to report F. fujikuroi as the causal agent of wilt disease in T. rutaecarpa. The chemical fungicide phenazine-1-carboxylic acid and the bio-fungicides shenqinmycin and tetramycin showed strong inhibitory effects against F. fujikuroi.

ObjectiveTo address the challenges of unstructured classical Chinese expressions， nested entity relationships， and limited annotated data in famous traditional Chinese medicine（TCM） case records， this study proposes a joint relation extraction framework that integrates data augmentation and entity mapping， aiming to support the construction of TCM diagnostic knowledge graphs and clinical pattern mining. MethodsWe developed an annotation structure for entities and their relationships in TCM case texts and applied a data augmentation strategy by incorporating multiple ancient texts to expand the relation extraction dataset. A cascade binary tagging framework for relation triple extraction（CasRel） model for TCM semantics was designed， integrating a pre-trained bidirectional encoder representations from transformers（BERT） layer for classical TCM texts to enhance semantic representation， and using a head entity-relation-tail entity mapping mechanism to address entity nesting and relation overlapping issues. ResultsExperimental results showed that the CasRel model， combining data augmentation and entity mapping， outperformed the pipeline-based Bert-Radical-Lexicon（BRL）-bidirectional long short-term memory（BiLSTM）-Attention model. The overall precision， recall， and F₁-score across 12 relation types reached 65.73%， 64.03%， and 64.87%， which represent improvements of 14.26%， 7.98%， and 11.21% compared to the BRL-BiLSTM-Attention model， respectively. Notably， the F₁-score for tongue syndrome relations increased by 22.68%（69.32%）， and the prescription-syndrome relations performed the best with the F₁-score of 70.10%. ConclusionThe proposed framework significantly improves the semantic representation and complex dependencies in TCM texts， offering a reusable technical framework for structured mining of TCM case records. The constructed knowledge graph can support clinical syndrome differentiation， prescription optimization， and drug compatibility， providing a methodological reference for TCM artificial intelligence research.

The inflammatory microenvironment is closely associated with the initiation and progression of osteoarthritis （OA）， specifically manifesting as macrophage activation， dysregulation of inflammatory cytokines， and redox imbalance. Following an overview of the pathological characteristics of the OA inflammatory microenvironment， this paper reviews the research progress on the mechanism of traditional Chinese medicine （TCM） intervening in OA by modulating the inflammatory microenvironment. It has been found that TCM monomers/active ingredients （such as total alkaloids from Strychnos nux-vomica ， quercetin， triptolide， etc.）， herb pairs （e.g. Angelica pubescens - Gentiana macrophylla ， Carthami Flos-Lycopodii Herba）， and TCM formulas （such as Zhuanggu jianxi formula， Duhuo jisheng decoction and Rongjin niantong formula， etc.） can inhibit macrophage activation， reduce the release of proinflammatory cytokines and the generation of reactive oxygen species by inhibiting multiple signaling pathways， including nuclear factor-κB， Wnt/ β -catenin， and mitogen-activated protein kinase， thereby alleviating the articular inflammatory microenvironment， restoring local joint homeostasis， and slowing the progression of OA.

This paper summarizes Professor WANG Yaoxian's experience in treating diabetic kidney disease （DKD） from the perspective of spleen and stomach based on the "internal heat leading to concretions" theory. It is considered that internal heat leading to concretions constitutes the core pathogenesis of DKD， with the spleen and stomach serving as the source of internal heat； therefore， treatment should be based on regulating the spleen and stomach. In the early stage of DKD， dysfunction of the spleen and stomach leads to the initial generation of internal heat. Common syndrome patterns include gastrointestinal heat accumulation and constrained heat in the liver and stomach， for which modified Gegen Qinlian Decoction （葛根芩连汤） can be used to clear heat bind while modified Dachaihu Decoction （大柴胡汤） is used to clear stomach and soothe liver， respectively. In the middle stage of DKD， weakness of the spleen and stomach results in the initial formation of concretions and conglomerations. Common patterns include spleen deficiency with prevalence of dampness and deficiency of both the spleen and kidney. Treatment emphasizes strengthening the spleen and resolving dampness， raising yang and boosting the stomach with modified Shengyang Yiwei Decoction （升阳益胃汤）， or supplementing spleen and boosting kidney， dissipating bind and dispe-ring concretions with modified Shenqi Dihuang Decoction （参芪地黄汤）， respectively. In the late stage of DKD， it is characterized by spleen and stomach depletion， and rampant accumulation of turbidity and toxin， and the common syndrome patterns are damp-turbidity obstruction in the middle jiao （焦） and spleen-kidney yang deficiency. Treatment aims to remove turbidity and harmonize the stomach， or to warm the kidney and strengthen the spleen while elimina-ting turbidity， using modified Dahuang Gancao Decoction（大黄甘草汤） and Jupi Zhuru Decoction （橘皮竹茹汤） or modified Baoyuan Decoction （保元汤） and Lizhong Decoction （理中汤）， respectively. In clinical practice， appropriate formulas and medications are flexibly selected according to specific syndromes.

The biological activity of chitinase in degrading chitin has garnered extensive attention,particularly for its potential applications in biological control.This study utilized four spore-form-ing Bacillus strains isolated from Dermacentor nuttalli ticks collected in the Hulunbuir region.Traditional bacterial culture methods were employed for isolation and identification,followed by 16S rRNA sequencing and phylogenetic analysis of the purified cultures.chitin-hydrolyzing strains were screened using colloidal chitin plates,and specific chitinase genes were detected via PCR.Fer-mentation was conducted at 37.0 ℃ for 4 d,and the supernatants were subjected to enzyme activity analysis using the DNS method.Four Gram-positive Bacillus strains were successfully isolated from tick tissue samples,they were identified as B.proteolyticus,B.paramycoides,B.thuringien-sis,and B.cereus,and renamed IMH/B-1,IMH/P-1,IMH/T-1,and IMH/C-1,respectively.PCR a-nalysis detected chitinase genes in B.proteolyticus and B.thuringiensis,while B.cereus and B.pa-ramycoides lacked these genes.However,three strains B.proteolyticus,B.thuringiensis,and B.ce-reus demonstrated significant(P＜0.01)chitin degradation activity on colloidal chitin.Enzyme ac-tivity assays revealed that chitinase activity ranged from 1.292 to 2.032 U/mL,with B.proteolytic-us exhibiting the highest activity 2.032 U/mL,followed by B.cereus 1.496 U/mL and B.thuring-iensis 1.324 U/mL.This study provides a foundation for further research and application of chiti-nase-producing Bacillus strains.

The role of osteoblast(OB)autophagy in regulating bone metabolism is a research hotspot in the field of biomedicine.OB autophagy can regulate osteoporosis(OP)induced by aging,oxidative stress,estrogen deficiency,and glucocorticoids(GCs)by mediating factors such as run and cysteine rich domain containing Beclin-1 interacting protein(RUBCN),silent information regulator of transcription 1(SIRT1),and osteoprotegerin(OPG).OB autophagy can also regulate OP by activating notch receptor(Notch)and forkhead box protein O subfamily(FoxO),up-regulating the expression of osteogenic transcription factors(such as Runx2 and Osterix),and mediating the amp-activated protein kinase(AMPK),mammalian target of rapamycin complex(mTOR),Wnt,and c-Jun n terminal kinase(JNK)pathways to act on OB and osteoclast(OC)differentiation.Exercise is an important means of improving OP,and its molecular mechanism is closely related to the up-regulation of phosphatidylinositol 3 kinase(PI3K),adenosine monophosphate(AMP),tumor necrosis factor-alpha(TNF-α),and SIRT1 expression.These in turn activate key factors or pathways(including AMPK,mTOR,Wnt,PI3K/protein kinase B(Akt)/mTOR,and nuclear transcription factor-KB(NF-κB)),regulate the expression of downstream target genes(β-catenin,mTOR,FoxO3a and B cell lymphoma-2(Bcl-2))to up-regulate the expression of autophagy factors(Beclin-1,autophagy related genes(ATG),and microtubule-associated protein 1 light chain 3(LC3)),and promote OB autophagy to restore the dynamic balance in the body,thereby regulating bone formation and bone resorption and improving OP.The relationships among exercise,OB autophagy and OP,however,remain unclear and there is currently a lack of systematic reviews.Here we review and analyze the mechanism of OB autophagy in relation to exercise-induced improvements in OP,and provide a new theoretical basis and research ideas for the prevention and treatment of OP.

Objective:To explore the characteristics of social skills and problem behaviors of children and adolescents with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), as well as the association with core symptoms.Methods:A total of 409 patients aged 5-18 years old with ASD or ADHD in the outpatient department of Nanjing Brain Hospital from 2023 to 2024, and 344 children and adolescents with typical development(TD) were recruited.All participants were matched in a ratio of 1∶1∶1 (ASD∶ADHD∶TD) according to gender and age, and 97 participants were included in each group for analysis.The Chinese version of the social skills improvement system rating scales(SSIS-RS-C) was used to evaluate social skills and problem behaviors, and autistic child behavior checklist(ABC), childhood autism rating scale(CARS), the Chinese version of the social communication questionnaire(SCQ) and the Chinese version of Swanson, Nolan, and Pelham, version Ⅳ scale-parent form(SNAP-Ⅳ) were used to evaluate the core symptoms of ASD and ADHD, respectively. SPSS 26.0 software was used to perform variance, Chi-square test, Spearman correlation analysis and multivariate Logistic regression analysis.Results:The social skills score of ASD group was lower than ADHD group ((61.53±24.26) vs (80.89±15.19), P<0.05), while the problem behavior score of ASD group was higher than ADHD group ((38.82±11.92) vs (34.00±12.45), P<0.05). In ASD group, the scores of ABC, CARS and SCQ were negatively correlated with the score of social skills ( r=-0.26--0.55, P<0.05). In ADHD group, the total score and each subscale of SNAP-Ⅳ were positively correlated with the score of problem behavior ( r=0.25-0.65, P<0.05). Multivariate Logistic regression analysis showed that empathy was a negative influencing factor of ASD ( B=-0.246, OR=0.782, P<0.05), and hyperactivity/inattention was a positive influencing factor of ASD ( B=0.589, OR=1.802, P<0.01), while only hyperactivity/inattention was a positive influencing factor of ADHD( B=0.779, OR=2.180, P<0.01). Conclusion:Children and adolescents with ASD and ADHD both have defects in social skills and problem behaviors, and these defects are associated with the core characteristics of their respective diseases.
