The multimorbidity of rheumatoid arthritis （RA） and periodontitis （PD） has drawn increasing attention， as both conditions are characterized by chronic inflammation， immune dysregulation， and progressive bone destruction. Modern research confirms that PD is a significant risk factor for RA development， and their coexistence mutually exacerbates disease progression. However， traditional Chinese medicine （TCM） currently lacks a systematic theoretical explanation for this complex multimorbid relationship. This study， based on the TCM theory of abnormal collateral， thoroughly examines the intrinsic connection between RA and PD multimorbidity， proposing "abnormal collateral as the pivot， with accumulated toxins eroding bone" as the core TCM pathogenesis. The research elucidates PD as the "origin of abnormal collateral"， where its pathogens act as toxic factors that invade the joints through collaterals， triggering RA via mechanisms such as molecular mimicry. The dynamic pathological progression of RA-PD multimorbidity can be described as follows： the displacement of Ying and Wei at the microscopic level manifests as immune hyperactivation， leading to collateral malnutrition； heat-toxins traversing collaterals induce collateral hyperactivity， resulting in pathological angiogenesis； ultimately， toxin accumulation at the pivotal abnormal collateral site erodes bone， activating the receptor activator of nuclear factor kappa-B ligand （RANKL）-receptor activator of nuclear factor kappa-B （RANK） signaling pathway-driven osteoclast differentiation. This theoretical framework innovatively integrates modern findings in oral microbiology， immune-inflammation， and bone metabolism， offering a holistic and dynamic perspective to understand the complexity of multimorbidity. Given the limited efficacy of current periodontal treatments for RA and the scarcity of reported TCM compound interventions for multimorbidity， the abnormal collateral theory proposes a systematic intervention strategy centered on "governing diseases through collaterals and regulating collaterals with herbs"， along with TCM therapeutic principles such as "unblocking， clearing， and nourishing collaterals". Potential herbal treatments for multimorbidity are also highlighted. Future research should focus on refining TCM syndrome patterns in multimorbid patients and leveraging omics technologies for deeper exploration， thereby providing a theoretical foundation and research direction for TCM in addressing complex multimorbid conditions.

Attention deficit and hyperactive disorder （ADHD） is the most common neurodevelopmental disorder of childhood. It seriously impairs academic achievement， social interaction， and vocational development， and increases the risk of accidental injury and substance abuse. In some cases， the symptoms may also exert an indirect disruptive effect on public order. Its aetiology involves interactions among genetic， perinatal environmental， and psychosocial factors that cannot be fully disentangled by single clinical studies. Therefore， a systematic evaluation of existing animal models is essential for revealing pathophysiology and developing novel therapies. Using the keywords "attention deficit and hyperactive disorder"， "models， animal"， "validity"， and their English equivalents， we systematically searched PubMed， Web of Science， CNKI， and Wanfang for publications from 2000 to 2025 （retrieving 328 publications） and added further references by citation tracking. Eighty-six rodent ADHD models that provided detailed construction protocols， behavioural assessments， neurobiological mechanisms， or pharmacological data were included and classified into spontaneous genetic， genetically engineered， and environmentally induced paradigms. Their face， construct， and predictive validity were compared. Among spontaneous genetic models， spontaneously hypertensive rats reproduce hyperactivity， impulsivity， and stimulant responses well， yet hypertension and sex differences limit specificity. Acallosal mouse strains link corpus callosum absence to ADHD-like behaviours， but neurotransmitter studies remain scarce. Genetically engineered rodents—including dopamine transporter， neurokinin-1 receptor and mediator complex subunit 23 knockout or conditional gene knockout lines—precisely dissect dopaminergic， noradrenergic， synaptic， or epigenetic pathways， yet generally lack full phenotypic coverage， social-deficit modelling， and comorbidity representation， and are accompanied by adverse effects such as growth retardation or ocular defects. Environmentally induced models employ lead， polychlorinated biphenyls， alcohol， nicotine exposures， 6-hydroxydopamine lesions， neonatal hypoxia， early social isolation， or maternal stress to recapitulate core symptoms. However， dose-schedule standardisation is lacking. Behavioural reversibility diverges from clinical persistence， and non-specific phenotypes such as anxiety or depression are common. Overall， no single paradigm simultaneously achieves high validity across all three dimensions. Currently， ADHD models have progressed from single-factor simulations to multidimensional evaluation， yet significant gaps remain in genetic-background standardisation， sex differences， cross-species translation， and syndrome-differentiation modelling under traditional Chinese medicine. Future directions should integrate genetic， environmental， and epigenetic interactions， establish life-span validation systems， and incorporate computational neuroscience alongside integrative Chinese-Western strategies to enhance clinical relevance and translational utility， thereby providing robust evidence-based support for mechanistic elucidation， drug screening and precision intervention in ADHD.

Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

BACKGROUND:Stem cell transplantation is a novel therapy for myocardial infarction,but the extremely hostile microenvironment in the infarct area results in low survival rate of stem cells and little long-term effect.Exercise preconditioning is a way to induce endogenous protective effects through exercise,which can be used as a new strategy for prevention and treatment of cardiac rehabilitation. OBJECTIVE:To evaluate whether exercise preconditioning potentiates the cardioprotective effects of adipose-derived stem cell transplantation following myocardial infarction in rats and to explore the mechanism of angiogenesis. METHODS:Six-week-old male SD rats were randomly divided into control group,modeling group,stem cell group,and stem cell plus exercise group.Acute myocardial infarction model was made by coronary artery occlusion,and sham operation was performed in control group.The stem cell plus exercise group underwent aerobic exercise for 8 weeks before modeling,and adipose-derived stem cell transplantation was performed 30 minutes after modeling.The stem cell group performed only adipose-derived stem cell transplantation.One and seven days after stem cell transplantation,the expression levels of myocardial total Akt(t-Akt),phosphorylated Akt(p-Akt),vascular endothelial growth factor(VEGF),total endothelial nitric oxide synthase(t-eNOS),and phosphorylated endothelial nitric oxide synthase(p-eNOS)protein were measured by western blotting,and the ratios of p-Akt/t-Akt and p-eNOS/t-eNOS were calculated.At 4 weeks after stem cell transplantation,the heart structure and function as well as myocardial blood flow were detected by color Doppler ultrasound diagnostic system.Myocardial infarction area was measured by TTC staining.Myocardial interstitial collagen deposition was examined by Masson staining.Myocardial capillary density was detected by immunofluorescence staining,and myocardial apoptosis was measured by TUNEL staining. RESULTS AND CONCLUSION:(1)Four weeks after stem cell transplantation:Compared with control group,left ventricular shortening fraction,left ventricular ejection fraction,myocardial capillary density,and myocardial blood flow decreased(P<0.05),myocardial infarction area,collagen volume fraction,and apoptosis increased(P<0.05)in the modeling group.Compared with the modeling group,the above indexes(except for left ventricular fractional shortening and left ventricular ejection fraction)in the stem cell group improved(P<0.05).Compared with the stem cell group,the above parameters were further improved in the stem cell plus exercise group(P<0.05).(2)One day after stem cell transplantation:Compared with the control group,the protein expression of t-Akt,p-Akt,VEGF,t-eNOS,p-eNOS and the ratio of p-Akt/t-Akt and p-eNOS/t-eNOS had no significant changes in the modeling group(P>0.05).Compared with the modeling group,there were no significant changes in the above indexes in the stem cell group(P>0.05),and p-Akt protein expression and the ratio of p-Akt/t-Akt were up-regulated in the stem cell plus exercise group(P<0.05).(3)Seven days after stem cell transplantation:Compared with the control group,the protein expression of p-Akt,VEGF,p-eNOS and the ratio of p-Akt/t-Akt and p-eNOS/t-eNOS were decreased in the modeling group(P<0.05).Compared with the modeling group,there were no significant changes in all parameters in the stem cell group(P>0.05),and the protein expression of p-Akt,VEGF p-eNOS and the ratio of p-Akt/t-Akt and p-eNOS/t-eNOS were increased in the stem cell plus exercise group(P<0.05).These findings confirm that exercise preconditioning can potentiate the therapeutic effect of adipose-derived stem cells on cardiac remodeling in rats with myocardial infarction,and its mechanism is associated with the promotion of myocardial angiogenesis and blood perfusion.

Nanometal materials have been extensively studied due to their non-toxic,stable,and efficient biological properties.Among them,nano-zinc oxide(ZnO-NPs),which exhibits good biocompatibility,is considered a promising antibacterial material for medical applications due to its broad-spectrum antibacterial effects and photocatalytic activity.The antibacterial mechanism of ZnO-NPs is not yet fully understood,but two widely recognized modes have been proposed:one is a non-contact mechanism dominated by reactive oxygen species(ROS)generated by ZnO-NPs and the release of Zn2+,and the other is a direct contact antibacterial mechanism involving the interaction between ZnO-NPs and bacterial cell wall components.These two distinct antibacterial mechanisms are attributed to the physicochemical properties of ZnO-NPs.As a wide-bandgap semiconductor,the antibacterial efficacy of ZnO-NPs is influenced not only by light exposure but also by factors such as particle size,concentration,morphology,as well as the type and structure of the target bacteria.Therefore,understanding the precise mechanisms is crucial for elucidating the antibacterial functions of ZnO-NPs against bacteria and fungi.This review summarizes the latest research progress on the antibacterial mechanisms of ZnO-NPs and their influencing factors,and provides an overview of the factors affecting the antibacterial performance of ZnO-NPs,offering a basis for a deeper understanding and application of ZnO-NPs in antibacterial therapy.

Photothermal therapy,as a novel anti-tumor treatment strategy,faces many challenges such as insufficient targeting,limited penetration ability,and inability to achieve long-term inhibition when used alone for anti-tumor treatment.Based on this,in this study,macrophage extracellular vesicles(MEVs)were modified onto the surface of a vector carrying CSF1R-siRNA and photothermal agents to form a multifunctional gene delivery vector MEVs@RNPs.It could induce the macrophages to reprogram from M2 type to M1 type,so as to achieve efficient photothermal and immunotherapy for triple negative breast cancer(TNBC).The basic physicochemical properties of each nanocarrier were characterized using nanoparticle size analyzer,UV-vis spectrometer,fluorescence spectrometer,thermal imaging instrument,etc.TNBC cells 4T1,endothelial cells Bend3,and macrophages 264.7 were used as in vitro experimental subjects for measurement of MEVs@RNPs.The ability to target tumor cells,kill tumor cells,and induce macrophage reprogramming in vitro was investigated.With Balb/c mice as the in vivo research object,a subcutaneous transplant tumor model was established in mice,and the changes in tumor volume and body weight of mice in different treatment groups were measured.In addition,further isolation of mouse blood and tumor tissue was performed,and hematoxylin-eosin(HE)staining,terminal deoxynucleotidyl transferase dUTP nick end labeling(TUNEL)method,and enzyme-linked immunosorbent assay(ELISA)method were used to determine the apoptosis and cytokine secretion of tumor cells for comprehensive evaluation of MEVs@RNPs.The results showed that the MEVs@RNPs could preferentially target tumor cells and induce stronger TNBC cell killing effect under photothermal conditions.Meanwhile,the results of flow cytometry and ELISA analysis showed that the MEVs@RNPs could promote the transformation of macrophages from M2 type to anti-tumor M1 type,significantly enhancing the secretion levels of anti-tumor cytokines tumor necrosis factor-α(TNF-α)and interleukin-12(IL-12).The in vivo anti-tumor treatment effect assessment of the MEVs@RNPs showed that under laser processing conditions,the MEVs@RNPs could significantly induce pathological necrosis and apoptosis of tumor cells,promote macrophage reprogramming and infiltration of CD4+/CD8+T cells into the tumor site,and enhance the secretion levels of TNF-α and IL-12,thereby comprehensively improving the therapeutic effect of TNBC.

Objective:To explore the molecular mechanism of TCM compound Shengxue Tongbian Granules in improving intestinal injury in septic rats through bioinformatics and experimental validation methods.Methods:The GSE131761 gene set was processed by bioinformatics to screen differential genes, then weighted gene co-expression network analysis (WGCNA) was applied to screen modular genes. The intersection of modular genes and differential genes was taken, and finally, the least absolute shrinkage and selection operator (LASSO) technique was applied to further obtain the key targets of sepsis, which was validated by experiments. Totally 72 SD rats were divided into sham-operation group, model group, dexamethasone group (0.15 mg/kg), Shengxue Tongbian Granules low- (0.3 g/kg), medium- (0.6 g/kg), and high-dosage (1.2 g/kg) groups, with 12 rats in each group. Corresponding drug interventions were administered to each treatment group before and 12 hours after modeling. The sham-operation group and the model group were gavaged daily with equal amounts of saline. Samples were collected after 24 hours. HE staining was used to detect the pathological morphology of intestinal tissues in each group of rats; ELISA was used to detect the levels of TNF-α, diamine oxidase (DAO), IL-6, IL-10, and myeloperoxidase (MPO) in rat serum. Immunohistochemistry was used to detect the protein expressions of MPO and neutrophil elastase (NE/LANE) in intestinal tissue, and Western blot was used to detect the protein expression of peptidyl arginine deaminase (PAD4) in intestinal tissue.Results:Seven final key genes related to sepsis were selected, namely ANXA3, CYP1B1, FCAR, LILRA5, PADI4, NOV, and S100A12. Experimental results showed that drug administration alleviated intestinal injury; compared with the model group, the levels of TNF-α, IL-6, MPO, and DAO decreased in the Shengxue Tongbian Granules high-dosage group ( P<0.05), the levels of ELANE and MPO were reduced in Shengxue Tongbian Granules low-, medium-, and high-dosage groups ( P<0.05), and PAD4 expression was reduced in the Shengxue Tongbian Granules high-dosage group ( P<0.05). Conclusion:Shengxue Tongbian Granules can improve the intestinal injury of septic rats, and the mechanism may be related to the inhibition of PAD4-mediated formation of NETs and the improvement of inflammatory response.

Objective To investigate the therapeutic efficacy of Zhi Long Huoxue Tongyu Capsules combined with Edaravone in the treatment of patients with ischemic cerebrovascular disease(ICVD)of qi deficiency and blood stasis syndrome,and to explore their effect on serum levels of soluble cluster of differentiation 40 ligand(sCD40L),lipoprotein phospholipase A2(Lp-PLA2),and glycated albumin(GA).Methods A total of 117 patients with ICVD of qi deficiency and blood stasis syndrome were randomly divided into control group 1,control group 2,and study group,with 39 patients in each group.The three groups were all given basic treatment with agents of diuretic,lipid regulation,antiplatelet,and antihypertensive,and additionally,control group 1 was given Edaravone,control group 2 was given Zhi Long Huoxue Tongyu Capsules,and the study group was given Zhi Long Huoxue Tongyu Capsules combined with Edaravone.The course of treatment for the three groups covered 14 days.Before and after treatment,the three groups were observed in the changes of National Institutes of Health Stroke Scale(NIHSS)scores for neurological function,modified Barthel Index(MBI)scores for activities of daily living(ADL),cerebral hemodynamics indicators[peak systolic velocity(PSV),end-diastolic velocity(EDV),mean velocity(Vm),pulsatility index(PI),and resistance index(RI)],neurofactors[neuron-specific enolase(NSE),S100β protein(S100β),and myelin basic protein(MBP)],vascular endothelial function indicators[von Willebrand factor(VWF),endothelin 1(ET-1),and nitric oxide(NO)],and levels of serum sCD40L,Lp-PLA2,and GA.After treatment,the clinical efficacy and the incidence of adverse reactions among the three groups of patients were compared.Results(1)After 14 days of treatment,the total effective rate of the study group was 94.87%(37/39),which was significantly higher than that of control group 1[71.79%(28/39)]and control group 2[76.92%(30/39)],the differences being statistically significant(P<0.05).No statistically significant difference was shown between control group 1 and control group 2(P>0.05).(2)After treatment,the cerebral hemodynamics indicators of PSV,EDV,Vm,and PI of the middle cerebral artery(MCA)in the three groups were increased compared with those before treatment(P<0.05),and the RI was decreased compared with that before treatment(P<0.05).The increase of PSV,EDV,Vm,and PI of the MCA and the decrease of RI in the study group were significantly superior to those in control group 1 and control group 2(P<0.05).No statistically significant differences in PSV,EDV,Vm,PI,and RI of MCA were shown between control group 1 and control group 2 after treatment(P>0.05).(3)After treatment,the serum sCD40L,Lp-PLA2,and GA levels in the three groups were decreased compared with those before treatment(P<0.05),and the decrease in the study group was significantly superior to that in control group 1 and control group 2(P<0.05).However,the differences of the serum levels after treatment between control group 1 and control group 2 were not statistically significant(P>0.05).(4)After treatment,the serum levels of neurofactors of NSE,S100β,and MBP in the three groups were all decreased compared with those before treatment(P<0.05),and the decrease of the serum levels in the study group was significantly superior to that in control group 1 and control group 2,while the differences of the serum levels after treatment between control group 1 and control group 2 were not statistically significant(P>0.05).(5)After treatment,the vascular endothelial function indicators of serum vWF and ET-1 levels in the three groups were decreased compared with those before treatment(P<0.05),and the serum NO level was increased compared with that before treatment(P<0.05).The decrease of serum vWF and ET-1 levels and the increase of serum NO level in the study group were significantly superior to those in control group-1 and control group-2(P<0.05),while the difference of serum vWF,ET-1 and NO levels after treatment between control group 1 and control group 2 were not statistically significant(P>0.05).(6)After treatment,the NIHSS scores for neurological function in the three groups were decreased(P<0.05)and the MBI scores for ADL were increased(P<0.05)compared with those before treatment,and the decrease of the NIHSS scores and the increase of the MBI scores in the study group was significantly superior to those in control group 1 and control group 2(P<0.05),while and the differences of NIHSS and MBI scores after treatment between control group 1 and control group 2 were not statistically significant(P>0.05).(7)The incidence rate of adverse reactions was 15.38%(6/39)in the study group,7.69%(3/39)in the control group 1,and 12.82%(5/39)in the control group 2,and the pairwise comparison between groups showed that the difference was not statistically significant(P>0.05).Conclusion Zhi Long Huoxue Tongyu Capsules combined with Edaravone exert certain efficacy in the treatment of patients with ICVD of qi deficiency and blood stasis syndrome,and the combined therapy is effective on improving blood circulation,restoring neurological function,enhancing the ADL,with higher safety.Its therapeutic mechanism may be related to the improvement of the vascular endothelial function,and the down-regulation of serum levels of neurofactors of NSE,S100 β,MBP,and serum expression levels of sCD40L,Lp-PLA2,and GA.
