Chronic heart failure （CHF） represents the terminal stage of cardiovascular diseases， and its prevalence remains high in China. In this study， existing animal models of CHF were retrieved and categorized. In combination with the characteristics of CHF from traditional Chinese medicine （TCM） and Western medicine perspectives， the models were weighted， and their clinical consistency was evaluated. The advantages and disadvantages of the models were assessed. Among them， models with higher TCM clinical consistency included the doxorubicin-induced model， the isoproterenol-induced model， and the left anterior descending coronary artery ligation model， each with a TCM consistency rate of 90%. The animal model established by the left anterior descending coronary artery ligation showed a high degree of clinical consistency with Western medicine， with a consistency rate of 82%. Each model exhibited its own advantages and disadvantages， with a general lack of modeling methods combining diseases and syndromes of TCM and Western medicine. At present， the inducement factors used for animal models are relatively singular， mainly reflecting the etiology and pathogenesis of Western medicine， with insufficient correlation to the pathogenesis of TCM. The characteristics of TCM syndromes are not fully represented， and the consistency between TCM and Western medicine is generally not high. TCM has the advantage of a multi-dimensional syndrome differentiation and treatment approach. It is necessary to integrate the characteristics of diseases and syndromes of TCM and Western medicine， adopt multi-factor modeling methods to reflect the pathological process of CHF， improve existing models， and establish animal models of CHF that better align with the characteristics of clinical diseases and syndromes of TCM and Western medicine， so as to provide a reliable reference for clinical prevention and treatment.

Objective: To prepare platelet membrane biomimetic liposomes loaded with vincristine sulfate (VCR) for targeted delivery to tumor. Methods: Vincristine sulfate liposomes (LIPO) were prepared using the pH-gradient method, followed by the fusion of platelet membranes and subsequent drug loading to obtain platelet membrane biomimetic liposomes (PLM-LIPO). The particle size, polydispersity index (PDI), Zeta potential, and drug encapsulation efficiency (EE%) of both liposomes were characterized. The tumor-targeting capability was evaluated through in vitro cellular experiments and in vivo biodistribution studies. Results: The optimal preparation conditions for LIPO were determined as follows: DPPC-to-cholesterol molar ratio of 1∶1, internal aqueous phase of 0.3 M pH 4.0 citrate buffer, external aqueous phase of 1 M Na HPO solution, drug-to-lipid ratio of 1∶10, drug loading temperature of 60℃, and loading time of 10 minutes. The LIPO exhibited a mean particle size of (147.3±2.24) nm, PDI of 0.078±0.014, Zeta potential of (-3.54±0.75) mV, and EE% of 91.37±0.47. For PLM-LIPO, prepared via membrane fusion followed by drug loading, the mean particle size was (185.3±3.61) nm, PDI was 0.075±0.022, Zeta potential was (-18.91±1.54) mV, and EE% was 63.36±2.45. In the CD62P validation experiment, the fluorescence intensity of PLM-LIPO was five times higher than that of LIPO. In vitro cellular uptake experiments revealed that PLM-LIPO showed 1.3-fold and 1.2-fold higher uptake rates compared to LIPO at 6 h and 12 h, respectively. In vivo experiments demonstrated that 1h after administration, the accumulation of PLM-LIPO at tumor sites was 4-fold higher than that of LIPO and 6-7 times higher than that in healthy mice. Conclusion: The platelet membrane biomimetic liposomes loaded with vincristine sulfate were successfully developed. Both cellular uptake and tissue distribution studies confirmed the PLM-LIPO enhanced tumor-targeting capability.

Purpose: Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms. Materials and Methods: Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A. Results: TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer. Conclusion TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.

The therapeutic effects of Yueju Pills on depression and cardiovascular diseases have been widely recognized. Previous studies have shown that the drug can significantly improve depressive-like behaviors induced by chronic unpredictable mild stress(CUMS) combined with atherosclerosis(AS). Given the complex pathogenesis of psychocardiac diseases, this study integrated metabolomics and network pharmacology to systematically elucidate the mechanism of Yueju Pills in alleviating depressive symptoms in psychocardiac diseases. The results demonstrate that, after Yueju Pill intervention, the levels of 9 abnormal metabolites in the hippocampus restore to normal ranges, primarily involving key pathways or signaling pathways, including the cyclic adenosine monophosphate(cAMP), mammalian target of rapamycin(mTOR), glycine/serine/threonine metabolism, and aminoacyl-tRNA biosynthesis. In a high-fat diet-induced CUMS ApoE~(-/-) mouse model, Yueju Pills significantly increases adenosine monophosphate(AMP) levels and decreases L-alanine and D-glyceric acid levels in the hippocampus. In conclusion, Yueju Pills exert antidepressant effects by regulating multiple metabolic axes, including glycine/serine/threonine metabolism and the cAMP, mTOR signaling pathways. Network pharmacology predictions reveal that the treatment of CUMS combined with AS by its core active components may be realized through modulating pathways concerning neuroinflammation and synaptic plasticity, including serine/threonine-protein kinase 1(AKT1), mitogen-activated protein kinase 1(MAPK1), and prostaglandin-endoperoxide synthase 2(PTGS2). This study provides a theoretical reference for the clinical application of Yueju Pills in alleviating the depressive symptoms of psychocardiac diseases.

Despite therapy with potent antiviral agents, chronic hepatitis B (CHB) patients remain at high risk of hepatocellular carcinoma (HCC). While metabolites have been rediscovered as active drivers of biological processes including carcinogenesis, the specific metabolites modulating HCC risk in CHB patients are largely unknown. Here, we demonstrate that baseline plasma from CHB patients who later developed HCC during follow-up exhibits growth-promoting properties in a case-control design nested within a large-scale, prospective cohort. Metabolomics analysis reveals a reduction in long-chain acylcarnitines (LCACs) in the baseline plasma of patients with HCC development. LCACs preferentially inhibit the proliferation of HCC cells in vitro at a physiological concentration and prevent the occurrence of HCC in vivo without hepatorenal toxicity. Uptake and metabolism of circulating LCACs increase the intracellular level of acetyl coenzyme A, which upregulates histone H3 Lys14 acetylation at the promoter region of KLF6 gene and thereby activates KLF6/p21 pathway. Indeed, blocking LCAC metabolism attenuates the difference in KLF6/p21 expression induced by baseline plasma of HCC/non-HCC patients. The deficiency of circulating LCACs represents a driver of HCC in CHB patients with viral control. These insights provide a promising direction for developing therapeutic strategies to reduce HCC risk further in the antiviral era.

Objective To investigate the clinical characteristics,treatment,and prognosis of children with perianal fistulizing Crohn's disease(pfCD).Methods A retrospective analysis was conducted on the children,aged 6-17 years,who were diagnosed with Crohn's disease(CD)from April 2015 to April 2023.According to the presence or absence of perianal fistulizing lesions,they were divided into two groups:pfCD(n=60)and non-pfCD(n=82).The two groups were compared in terms of clinical characteristics,treatment,and prognosis.Results The incidence of pfCD was 42.3%(60/142).The proportion of males in the pfCD group was higher than that in the non-pfCD group.Compared with the non-pfCD group,the pfCD group had a significantly higher proportion of children with involvement of the colon and small intestine or those with upper gastrointestinal lesions(P<0.05).Compared with the non-pfCD group,the pfCD group had a significantly higher rate of use of infliximab during both induction and maintenance treatment(P<0.05).In the pfCD group,the children with complex anal fistula accounted for 62%(37/60),among whom the children receiving non-cutting suspended line drainage accounted for 62%(23/37),which was significantly higher than the proportion among the children with simple anal fistula patients(4%,1/23)(P<0.05).There were no significant differences between the two groups in mucosal healing rate and clinical remission rate at week 54 of treatment(P>0.05).The pfCD group achieved a fistula healing rate of 57%(34/60)at week 54,and the children with simple anal fistula had a significantly higher rate than those with complex anal fistula(P<0.05).Conclusions There is a high incidence rate of pfCD in children with CD,and among the children with pfCD,there is a high proportion of children with the use of biological agents.There is a high proportion of children receiving non-cutting suspended line drainage among the children with complex anal fistula.The occurrence of pfCD should be closely monitored during the follow-up in children with CD.
