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.

Objective: To examine the prevalence of e-cigarette use and associated factors among primary and secondary school students in Pudong New Area, Shanghai, and to explore the pathways linking harm perception of e-cigarettes, interpersonal social influence, and attitudes toward e-cigarette use with experimentation behavior, in order to provide scientific basis for further optimizing the prevention and control strategies of e-cigarette among adolescents. Methods: From September to October 2025, a multi stage cluster random sampling method was used to select 5 144 primary and secondary school students aged 8-19 years from 47 primary and secondary schools in Pudong New Area, Shanghai, to conduct an anonymous questionnaire survey. The questionnaire collected information on e-cigarette use, harm perception of e-cigarette, interpersonal social influence, and attitudes toward e-cigarette use. The Chi-square test was applied to analyze the differences in cigarette and e-cigarette use behavior among primary and secondary school students with different demographic characteristics. Structural equation modeling (SEM) was constructed using Mplus 8.3 software, and the bootstrap method was utilized to test the mediating effects. Results: The reported rates of cigarette experimentation, e-cigarette experimentation, and current e-cigarette use among primary and secondary school students were 1.85%, 2.10%, and 0.70%, respectively. Higher reporting rates of e-cigarette experimentation were observed among boys (2.82%), secondary school students aged 16-19 (3.39%), senior high school students (3.05%), and those with weekly pocket money >100 yuan ( 6.11% ) ( χ 2=11.67, 8.61, 8.00, 54.18, all P <0.05). Structural pathway analysis results demonstrated that e-cigarette harm perception positively predicted interpersonal social influence ( β =0.61) and e-cigarette use attitude ( β = 0.53 ), and interpersonal social influence ( β =0.65) and e-cigarette use attitude ( β =0.25) further promoted e-cigarette experimentation behavior among primary and secondary school students (all P <0.01), with interpersonal social influence playing a major mediating role (indirect effect=0.40). Conclusions E-cigarette experimentation behavior among primary and secondary school students in Pudong New Area is jointly influenced by multiple psychosocial factors. Intervention strategies should strengthen interpersonal social factors such as family and peers on the basis of health education, thereby constructing a comprehensive prevention and control strategy for e-cigarette use among primary and secondary school students.

This paper proposes a five-in-one diagnosis and treatment model of "disease-mechanism-syndrome-symptom-method" based on treatment guided by mechanism differentiation. The model consists of five component including disease identification， mechanism differentiation， syndrome differentiation， symptom differentiation， and the formulation of therapeutic strategies. Disease identification refers to the diagnosis of diseases in both traditional Chinese medicine （TCM） and western medicine， aiming to clarify disease progression rules. Mechanism differentiation focuses on grasping the essential characteristics of the disease. Syndrome differentiation emphasizes the stage-specific features of disease evolution. Symptom differentiation highlights the patient's most urgent complaints and suffering. Finally， a comprehensive therapeutic strategy is developed， including internal medication， external applications， and non-pharmacological therapies. The five components of "disease-mechanism-syndrome-symptom-method" are organized in a sequential and progressive manner， forming an integrated whole that spans the entire diagnostic and therapeutic process.Disease identification represents the starting point， while mechanism differentiation serves as the core， and therapeutic formulation is the endpoint of the model， with the aim of achieving more precise treatment and improving clinical efficacy.

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 change trend and related mechanism of resting metabolic rate induced by corticosterone in mice,and observe the intervention effects of Zhibai Dihuang Pill and Jinkui Shenqi pill.Methods Sixty-four mice were randomly divided into short-term and long-term groups,and each group was randomly divided into four groups.Mice in CORT group,ZBDH group and JKSQ group were given sterile drinking water containing corticosterone,and mice in Ctrl group were given sterile drinking water containing 1%anhydrous ethanol.Mice in ZBDH group and JKSQ group were given Chinese medicine by gavage.RMR of mice in each group was dynamically monitored during modeling and Chinese medicine intervention.The morphology of mitochondria in liver and muscle were observed by transmission electron microscope.The TR expression level in liver and muscle tissues of each group was observed by immunofluorescence,and MDA and ATP levels were detected in liver and muscle tissues of each group.levels of ACTH,TSH,INS,T3,T4,FT3,FT4,8-OHdG,FGF-21,GDF-15,L-lactic acid and pyruvic acid in serum were also detected.Results Compared with Ctrl group,the mitochondrial morphology of liver and muscle tissues in CORT group was damaged,and the expression of TR was decreased.In short-term(Day 8),RMR,ATP in liver,serum T4,ACTH and INS levels were significantly increased in the CORT group,while serum FGF-21,TSH levels and MDA in liver were significantly decreased.In long term(Day 56),RMR,serum 8-OhdG,INS,and ATP in liver and muscle were significantly decreased in the CORT group,serum FGF-21,GDF-15,T3,T4,FT3,FT4,MDA in liver and muscle were significantly increased.Compared with CORT group,in short term,RMR,serum L(+)-lactate in ZBDH group were significantly decreased,while serum 8-OHdG and the expression of TRα in muscle were significantly increased.In JKSQ group,the mitochondrial morphology of muscle tissue was improved,the expression of TRα and serum FGF-21 were significantly increased,while serum L(+)-lactic acid,FT4 and ATP in liver were significantly decreased.In long term,serum FGF-21 was significantly lower in ZBDH group,and in JKSQ group,RMR,ATP in liver tissue and TRα expression in muscle were significantly increased,while the levels of FGF-21,GDF-15,T3,FT4 in serum and MDA in muscle tissue were significantly decreased.Conclusion CORT induced RMR to increase first and then decrease with the intervention time.In the short term,Zhibai Dihuang Pill significantly decreased RMR in mice,while in the long term,Jinkui Shenqi Pill significantly increased RMR.The mechanism may be related to mitochondrial injury,thyroxine secretion and thyroxine receptor expression.

The aim of this study is to explore the mechanism of apigenin against transmissible gas-troenteritis virus(TGEV)infection based on network pharmacology and molecular docking.The potential targets of apigenin were obtained from Pharmmapper,Pubchem and other databases.The PubMed database was searched to obtain the relevant targets of TGEV infection.The intersection targets of apigenin and TGEV infection were identified by Draw Venn Diagram online program.A"drug-disease-target"network was constructed using STRING database and Cytoscape 3.8.2 soft-ware.Protein-protein interaction relationships were obtained from the STRING database,and core targets were analyzed.The intersection targets were subjected to GO function and KEGG pathway enrichment analysis using the DAVID database.Finally,the analysis results were validated through molecular docking and in vitro cell experiments.The study identified 431 targets for apigenin,1 177 targets for TGEV infection,and 50 intersection targets for apigenin and TGEV infection.GO enrichment analysis indicated that apigenin was mainly involved in regulating cell differentiation,cell membrane raft formation,apoptosis,and inflammatory responses.The top 15 statistically sig-nificant KEGG enrichment results mainly involve the PI3K-Akt signaling pathway and TNF signa-ling pathway.Docking analysis showed that apigenin had the strongest interaction with matrix metalloproteinase 3(MMP3)with an affinity of-9.5 kJ/mol and the binding activity of MMP3 was the best.The results of in vitro experiments demonstrated that treatment of different concen-trations of apigenin significantly reduced virus titers,virus genome copies,and the expression lev-els of MMP3 and its upstream and downstream proteins compared to the virus-infected group.Api-genin may exert its anti-TGEV effects through multiple targets and pathways,possibly by regula-ting the NF-κB-MMP3-IL-1β signaling pathway.
