OBJECTIVE To explore the improvine mechanism of Yifei xuanfei jiangzhuo formula (YFXF) on vascular dementia (VAD) model rats based on the growth factor receptor-bound protein 2 (GRB2)/extracellular signal-regulated kinase (ERK)/cardiolipin synthase 1 (CRLS1) pathway. METHODS VAD rat model was established by permanent bilateral common carotid artery ligation. Forty-eight successfully modeled rats were randomly divided into the model group (normal saline), donepezil hydrochloride group (positive control group, 0.2 g/kg), and YFXF low- and high-dose groups (12.18 and 24.36 g/kg, calculated based on the total amount of crude drug), respectively. In addition, a sham operation group (normal saline) was set up. There were 12 rats in each group. Daily intragastric administration of drug or normal saline was performed for 30 consecutive days. After the last administration, the spatial cognitive ability of the rats was evaluated, the pathological morphology of the hippocampus was observed, the contents of tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4) in serum were detected, the expression levels of GRB2/ERK/CRLS1 pathway-related proteins and the mRNA levels of GRB2, CRLS1, NADH dehydrogenase subunit 1(ND1), Tafazzin (TAZ), phospholipid scramblase 3(PLSCR3) and the ATP content in hippocampal tissue were measured. RESULTS Compared with the sham operation group, the escape latency of rats in the model group was significantly prolonged ( P <0.05), and the number of crossing platform was significantly reduced ( P <0.05), while the number of pyramidal cells and Nissl bodies in the hippocampus decreased sharply; the content of TNF-α in serum was significantly increased ( P <0.05), and the content of IL-4 was significantly decreased ( P <0.05); the expression levels of GRB2 and CRLS1 proteins, the phosphorylation level of ERK protein, the relative expression levels of GRB2, CRLS1,ND1, TAZ, and PLSCR3 mRNA, and the content of ATP in hippocampal tissue were significantly decreased ( P <0.05). Compared with the model group, the above pathological changes in the hippocampal tissue of each administration group were alleviated, and the quantitative indicators were significantly restored ( P <0.05). CONCLUSIONS YFXF may improve hippocampal neuron injury in VAD rats by activating the GRB2/ERK/CRLS1 pathway, maintaining cardiolipin homeostasis, and improving mitochondrial energy metabolism.

ObjectiveThis paper aims to investigate the material basis of the anti-inflammatory efficacy and mechanism of action of Bushen Tongdu prescription (BSTDP). MethodsThe chemical components of BSTDP and its blood-absorbed components in vivo were systematically identified by using ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry (UPLC-LIT-Orbitrap-MS). Network pharmacology was employed to screen blood-absorbed bioactive components and potential targets of this formula. A protein-protein interaction (PPI) network of core targets was constructed to conduct enrichment analysis. Molecular docking was further utilized to verify the binding affinity between key components and targets. The inflammatory model was established and verified in vivo by using a transgenic zebrafish Tg (mpx: GFP). At three days post-fertilization (3 dpf), larvae of zebrafish were randomly assigned to blank group, model group, positive drug dexamethasone acetate group (75 μmol·L-1), and BSTDP groups with low, medium, and high doses (500, 1 000, and 2 000 mg·L-1). The distribution and quantity of neutrophils in the yolk sac region were observed under a fluorescence microscope. The mRNA expression levels of key genes in the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor kappa-B (NF-κB) signaling pathway and inflammatory factors including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α) were detected by Real-time quantitative polymerase chain reaction (Real-time PCR). ResultsA total of 120 chemical components were identified in BSTDP, among which 26 original components were confirmed by using serum pharmacochemical methods. A total of 227 common targets linking rheumatoid arthritis (RA) and the blood-absorbed components were screened by network pharmacology. It is suggested that pseudobrucine, vomicine, sinapine, rehmannioside, cinnamyl alcohol glycoside, and methylephedrine exert anti-inflammatory effects by acting on core targets including protein kinase B1 (Akt1), signal transducer and activator of transcription 3 (STAT3), tumor necrosis factor (TNF), TLR4, mitogen-activated protein kinase 14 (MAPK14), and phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α (PIK3CA), thereby modulating multiple signaling pathways such as TLR4 and NF-κB. In vivo verification in zebrafish demonstrates that the maximum tolerable concentration of Bushen Tongdu Formula is 2 000 mg·L-1. Compared to those in the blank group, zebrafish in the model group showed a significantly higher number of neutrophils in the yolk sac region (P<0.01) and rising mRNA levels of TLR4, MyD88, NF-κB, TNF-α, IL-6, and IL-1β (P<0.01). Compared to that in the model group, the number of neutrophils was significantly reduced in BSTDP groups with medium and high doses, as well as the dexamethasone acetate group (P<0.05, P<0.01). There was no statistically significant difference in the low dose group. The mRNA expression levels of TLR4, MyD88, NF-κB, TNF-α, IL-6, and IL-1β were significantly down-regulated (P<0.05, P<0.01). ConclusionThis paper identifies the material basis of the efficacy of BSTDP, demonstrating that the formula can exert an anti-inflammatory effect through the TLR4/MyD88/NF-κB signaling pathway. The results provide scientific experimental evidence for its further clinical application.

Diabetic kidney disease(DKD) is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise, DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease(ESRD), posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD, with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4(TLR4)/nuclear transcription factor-κB(NF-κB)/B-cell lymphoma-2(Bcl-2)/cysteinyl aspartate-specific proteinase(Caspase)-3, protein kinase R-like endoplasmic reticulum kinase(PERK)/eukaryotic initiation factor 2α(eIF2α)/activating transcript factor 4(ATF4)/CCAAT enhancer-binding protein homologous protein(CHOP), phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/glycogen synthase kinase-3β(GSK-3β), Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3), adenosine monophosphate-activated protein kinase(AMPK)/mammalian target of rapamycin(mTOR) and silent information regulator 1(SIRT1)/tumor suppressor protein 53(p53), thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine(TCM), leveraging its unique therapeutic advantages of multi-target, multi-component and multi-pathway approaches, has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile, traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation, detoxifying and dredging collaterals, tonifying kidney essence, and removing stasis and purging turbidity, thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this, this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms, while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components, compound formulations, and proprietary Chinese medicines on DKD through modulation of these pathways, with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

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.
9.From Golgi Stress to Golgiphagy—a New Regulatory Model Involved in Glucose and Lipid Metabolism

The Golgi body, a core organelle in eukaryotic cells, plays a critical role in protein modification, sorting, vesicular transport, and serves as a key site for lipid synthesis and glycosylation. Glucose and lipid metabolism are central processes for cellular energy maintenance and biosynthesis, and are closely linked to Golgi function. Recent studies have revealed the extensive involvement of the Golgi body in regulating glucose and lipid metabolism, where maintaining its structural and functional homeostasis is crucial for normal physiological activity. Under various stress conditions such as acidosis, hypoxia, and nutrient deficiency, the Golgi body undergoes structural and functional disruption, leading to Golgi stress. This in turn activates specific signaling pathways, such as those mediated by the cAMP-responsive element binding protein 3 (CREB3) and proteoglycans, to alleviate Golgi stress and enhance Golgi function. Golgi stress contributes to glucose and lipid metabolic disorders by affecting the activity of insulin receptors, glucose transporters, and lipid metabolism-related enzymes. For example, Golgi stress triggers the cleavage and release of the active fragment of CREB3, which enters the nucleus and upregulates the transcription of ADP-ribosylation factor 4 (ARF4) and key gluconeogenic enzymes, including phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase). ARF4 promotes vesicle retrograde transport between the Golgi and endoplasmic reticulum, maintains secretory capacity, and enhances hepatic glucose output. This pathway is particularly active under high-fat or lipotoxic stress, leading to fasting hyperglycemia. When damaged Golgi components accumulate beyond a tolerable threshold, the cell initiates an autophagic response, selectively encapsulating the damaged Golgi into autophagosomes, which then fuse with lysosomes to form autolysosomes, leading to Golgiphagy. This process results in the degradation and clearance of damaged Golgi, thereby regulating Golgi quantity, quality, and function. Golgiphagy also plays a significant role in regulating glucose and lipid metabolism. For instance, under high-glucose conditions, autophagic flux may be suppressed, impairing the timely clearance and renewal of damaged Golgi, compromising its normal function, and further exacerbating glucose metabolism disorders. Additionally, Golgiphagy may participate in lipid degradation and influence lipid synthesis and transport. Research indicates that Golgi stress and Golgiphagy play important roles in glucose and lipid metabolism-related diseases. For example, the leucine zipper protein (LZIP) under Golgi stress conditions can promote hepatic steatosis. In mouse primary cells and human tissues, LZIP induces the expression of apolipoprotein A-IV (APOA4), which increases peripheral free fatty acid uptake, resulting in lipid accumulation in the liver and contributing to the development of fatty liver disease. This review systematically outlines the structure and function of the Golgi apparatus, the molecular regulatory mechanisms of Golgi stress and Golgiphagy, and their synergistic roles. It further elaborates on how Golgi stress and Golgiphagy participate in the regulation of glucose and lipid metabolism, discusses their clinical significance in related diseases such as diabetes, fatty liver disease, and obesity, and highlights potential novel therapeutic strategies from the perspective of Golgi-targeted medicine
