ObjectiveTo explore the mechanism of Sangpi Zhike prescription in treating cough after respiratory syncytial virus (RSV) infection through the "lung-intestine co-treatment" approach using network pharmacology and animal experimental validation. MethodsActive ingredients and targets of Sangpi Zhike prescription were retrieved from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. Disease targets were obtained from GeneCards and Online Mendelian Inheritance in Man(OMIM) databases. Protein-protein interaction (PPI) networks and drug-component-target networks were constructed using overlapping targets between drugs and diseases to identify core targets. Gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analyses were performed on the overlapping targets. Sixty mouse models were established: 10 as the normal group, and the remaining mice were infected with RSV via slow nasal drip of RSV suspension, with cough induced using capsaicin solution. After modeling, mice were divided into a model group, a Montelukast Sodium group (1 mg·kg-1·d-1), and low, medium, and high dose groups of Sangpi Zhike prescription (4.875,9.75,and 19.5 g·kg-1·d-1), with 10 mice per group. From day 14 after RSV infection, the normal and model groups received saline via gavage, while other groups received corresponding drug treatments once daily for 5 d. Hematoxylin-eosin(HE) staining was used to observe pathological changes in lung and intestinal tissue. The protein content of extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphorylated (p)-ERK1/2 in the lung and colon tissue of mice was detected by Western blot. Real-time polymerase chain reaction(Real-time PCR) detected ERK1/2 mRNA expression in lung and intestinal tissue. Immunohistochemistry assessed p-MEK1/2, p-ERK1/2, p-c-Fos protein levels, and inflammatory cytokines interleukin(IL)-4 and (TNF)-α in lung and colon tissue. ResultsNetwork pharmacology identified 184 active ingredients and 684 targets in Sangpi Zhike prescription, with 1 344 RSV-related disease targets and 209 overlapping targets. Core targets included TNF, Fos, and Jun. KEGG enrichment revealed 179 pathways, primarily mitogen-activated protein kinase(MAPK), cancer, TNF, and IL-17 signaling pathways. Animal experiments showed that, compared to those of the normal group, the lung tissue sections of the model group showed typical inflammatory damage, infiltration of inflammatory cells, rupture of alveolar septa, extensive alveolar fusion, and disruption of tight junctions between single-layer columnar epithelial cells in the intestinal tissue. The values of p-ERK1/2 and ERK1/2 in lung and intestinal tissue were significantly increased (P<0.01), and the expression level of ERK1/2 mRNA was significantly elevated (P<0.01). The levels of ERK1/2, p-MEK1/2, p-ERK1/2, p-c-Fos, IL-4, and TNF-α along the ERK pathway were significantly increased (P<0.05, P<0.01). Compared to the model group, Sangpi Zhike prescription groups showed reduced lung and intestinal inflammation, decreased p-ERK1/2/ERK1/2 ratios (P<0.05,P<0.01), lower ERK1/2 mRNA levels, and downregulated ERK pathway proteins (P<0.05,P<0.01). ConclusionSangpi Zhike prescription alleviates cough and intestinal symptoms after RSV infection via the "lung-intestine co-treatment" mechanism by suppressing expression levels of ERK1/2, p-MEK1/2, p-ERK1/2, p-c-Fos, IL-4, and TNF-α on ERK pathway components, thereby mitigating lung and intestinal pathological damage.

ObjectiveTo investigate the ameliorative effects and related mechanisms of the Zuogui Jiangtang Shuxin prescription (ZJSP) on glucose and lipid metabolism disorders in MKR mice with diabetic cardiomyopathy (DCM), with a focus on elucidating its regulatory role on the adenosine monophosphate-activated protein kinase (AMPK)/forkhead box protein O1 (FoxO1)/cluster of differentiation 36 (CD36) signaling pathway and lipid deposition. MethodsFifty 8-week-old male MKR mice were fed a high-fat diet for four weeks and then intraperitoneally injected with streptozotocin (STZ) while maintaining a high-fat diet to establish a DCM model. The mice were randomly divided into the model group, the low-dose(14.43 g·kg-1)and high-dose(28.86 g·kg-1) ZJSP groups, and the metformin group (0.25 g·kg-1), with age-matched FVB mice as a normal control group. Each group received intragastric administration of normal saline or corresponding concentrations of ZJSP at equal volumes. After four weeks, fasting blood glucose (FBG) and cardiac function were measured. Blood was collected from the eyeballs under anesthesia to detect fasting insulin (FINS) and blood lipid levels. Myocardial tissue morphology was observed by hematoxylin-eosin (HE) staining, and lipid deposition in the heart was assessed using oil red O staining. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to measure the mRNA expression levels of AMPK, FoxO1, and CD36 in myocardial tissues. Western blot was employed to detect the protein expression levels of AMPK, p-AMPK, FoxO1, p-FoxO1, and CD36. ResultsCompared with the control group, the model group showed significantly increased levels of FBG and FINS (P<0.01), elevated levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) (P<0.01), and significantly decreased left ventricular ejection fraction (EF) and fractional shortening (FS) values (P<0.01). HE staining revealed marked cardiomyocyte hypertrophy, disarray, and widened intercellular spaces in myocardial tissues. Oil Red O staining showed extensive red deposition areas and fine lipid droplet accumulation in the myocardial tissue. AMPK mRNA expression was decreased, while FoxO1 and CD36 mRNA expressions were significantly increased (P<0.01). The p-AMPK/AMPK protein expression ratio in myocardial tissues was significantly reduced, while the p-FoxO1/FoxO1 protein expression ratio and CD36 protein expression levels were significantly increased (P<0.01). Compared with the model group, all treatment groups exhibited significantly reduced FBG (P<0.01), decreased FINS and blood lipid levels (TG, TC, LDL-C) (P<0.05, P<0.01), improved cardiac function (P<0.05), noticeable amelioration of myocardial histopathological morphology and lipid deposition, increased AMPK mRNA expression (P<0.01), with significantly downregulated FoxO1 and CD36 mRNA expressions (P<0.01), elevated p-AMPK/AMPK protein expression levels in myocardial tissue (P<0.05), significantly decreased p-FoxO1/FoxO1 ratios (P<0.01), and downregulated CD36 protein expression levels (P<0.05, P<0.01). ConclusionZJSP exerts a protective effect on the heart in type 2 DCM of MKR mice, and its mechanism may be associated with the regulation of the AMPK/FoxO1/CD36 signaling pathway.

Obesity is a worldwide health problem. An imbalance in energy metabolism is an important cause of obesity and related metabolic diseases. Our previous studies showed that inhibition of miR-429 increased the protein level of uncoupling protein 1 (UCP1) in beige adipocytes; however, whether local inhibition of miR-429 in subcutaneous adipose tissue affects diet-induced obesity and related metabolic disorders remains unclear. The aim of this study was to investigate the effect of local overexpression of miR-429 sponge in subcutaneous adipose tissue on obesity and related metabolic disorders. The control adeno-associated virus (AAV) or AAV expressing the miR-429 sponge was injected into mouse inguinal white adipose tissue. Seven days later, the mice were fed a high-fat diet for 10 weeks to induce obesity. The effects of the miR-429 sponge on body weight, adipose tissue weight, plasma glucose and lipid levels, and hepatic lipid content were explored. The results showed that the overexpression of miR-429 sponge in subcutaneous white adipose tissue reduced body weight and fat mass, decreased fasting blood glucose and plasma cholesterol levels, improved glucose tolerance, and alleviated hepatic lipid deposition in mice. Mechanistic investigation showed that the inhibition of miR-429 significantly upregulated the expression of UCP1 in adipocytes and adipose tissue. These results suggest that local inhibition of miR-429 in subcutaneous white adipose tissue ameliorates obesity and related metabolic disorders potentially by upregulating UCP1, and miR-429 is a potential therapeutic target for the treatment of obesity and related metabolic disorders.

Cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic disorders are the 3 major chronic diseases threatening human health, which are closely related and often coexist, significantly increasing the difficulty of disease management. In response, the American Heart Association (AHA) proposed a novel disease concept of “cardiovascular-kidney-metabolic (CKM) syndrome” in October 2023, which has triggered widespread concern about the co-treatment of heart and kidney diseases and the prevention and treatment of metabolic disorders around the world. This review posits that effectively managing CKM syndrome requires a new and multidimensional paradigm for diagnosis and risk prediction that integrates biological insights, advanced technology and social determinants of health (SDoH). We argue that the core pathological driver is a “metabolic toxic environment”, fueled by adipose tissue dysfunction and characterized by a vicious cycle of systemic inflammation and oxidative stress, which forms a common pathway to multi-organ injury. The at-risk population is defined not only by biological characteristics but also significantly impacted by adverse SDoH, which can elevate the risk of advanced CKM by a factor of 1.18 to 3.50, underscoring the critical need for equity in screening and care strategies. This review systematically charts the progression of diagnostic technologies. In diagnostics, we highlight a crucial shift from single-marker assessments to comprehensive multi-marker panels. The synergistic application of traditional biomarkers like NT-proBNP (reflecting cardiac stress) and UACR (indicating kidney damage) with emerging indicators such as systemic immune-inflammation index (SII) and Klotho protein facilitates a holistic evaluation of multi-organ health. Furthermore, this paper explores the pivotal role of non-invasive monitoring technologies in detecting subclinical disease. Techniques like multi-wavelength photoplethysmography (PPG) and impedance cardiography (ICG) provide a real-time window into microcirculatory and hemodynamic status, enabling the identification of early, often asymptomatic, functional abnormalities that precede overt organ failure. In imaging, progress is marked by a move towards precise, quantitative evaluation, exemplified by artificial intelligence-powered quantitative computed tomography (AI-QCT). By integrating AI-QCT with clinical risk factors, the predictive accuracy for cardiovascular events within 6 months significantly improves, with the area under the curve (AUC) increasing from 0.637 to 0.688, demonstrating its potential for reclassifying risk in CKM stage 3. In the domain of risk prediction, we trace the evolution from traditional statistical tools to next-generation models. The new PREVENT equation represents a major advancement by incorporating key kidney function markers (eGFR, UACR), which can enhance the detection rate of CKD in primary care by 20%-30%. However, we contend that the future lies in dynamic, machine learning-based models. Algorithms such as XGBoost have achieved an AUC of 0.82 for predicting 365-day cardiovascular events, while deep learning models like KFDeep have demonstrated exceptional performance in predicting kidney failure risk with an AUC of 0.946. Unlike static calculators, these AI-driven tools can process complex, multimodal data and continuously update risk profiles, paving the way for truly personalized and proactive medicine. In conclusion, this review advocates for a paradigm shift toward a holistic and technologically advanced framework for CKM management. Future efforts must focus on the deep integration of multimodal data, the development of novel AI-driven biomarkers, the implementation of refined SDoH-informed interventions, and the promotion of interdisciplinary collaboration to construct an efficient, equitable, and effective system for CKM screening and intervention.

Acupotomy therapy demonstrates the definite clinical efficacy on knee osteoarthritis (KOA). After reviewing systematically the mechanism studies on acupotomy for KOA over the past 5 years, It is revealed that acupotomy synergistically intervenes in the pathological progression of KOA through multi-target approaches, such as regulating cartilage homeostasis, restoring skeletal muscle function, alleviating synovial inflammatory responses, remodeling subchondral bone, and neuromodulation. But the current research still limits to single-tissue phenotypic observation, and is insufficiency in the in-depth exploration of multi-tissue synergistic interactions and molecular upstream-downstream regulatory mechanisms. Future studies should focus on the inheritance and innovation of acupotomy theory, and integrating multi-omics analytical technologies, artificial intelligence, and novel biochemical detection methods. The mechanism research targets on the interaction mechanisms among tissues, direct effects of acupotomy, immune-inflammatory regulatory mechanisms, and analgesic mechanisms, so as to comprehensively elucidate the therapeutic mechanism of acupotomy for KOA.

Aim To study the protective effect of the silibinin derivative Sil-1 on acute myocardial ischemia in SD rats and its mechanism of action.Methods Af-ter 18 hours of oxygen-glucose deprivation and treat-ment of H9c2 cells,the protective effect of Sil-1 on rat cardiomyocytes was examined.SD rats were treated 30 minutes before surgery,followed by 24 h ligation of the left anterior descending coronary artery.The cardiopro-tective effects of Sil-1 and its mechanisms for improving myocardial ischemic injury were investigated using pro-teomics technology.Results In vitro,compared with the control group,the activity of H9c2 cells in the mod-el group showed reduced cell viability,increased dead cells,elevated ROS and higher levels of LDH and in-flammatory cytokines TNF-α,IL-1β and IL-6 in the culture medium.Sil-1 could improve the above condi-tions to different degrees.In vivo,compared with the control group,rats in the model group showed signifi-cantly higher T waves on electrocardiogram,significant ischemic areas in the heart section,disorganized ar-rangement of cardiomyocytes,increased inflammatory factor infiltration and elevated CK,CK-MB,LDH and inflammatory factors TNF-α,IL-6 and IL-1β.Besides,NF-κB phosphorylation levels in myocardial tissue in-creased.Sil-1 improved the above conditions to varying degrees.The results of proteomics showed that 90 pro-teins were found between the control vs model group and the Sil-1 vs model group,and KEGG enrichment a-nalysis showed that MAPK,chemokines,VEGF and other signaling pathways were abundant.Western blot results showed that Sil-1 blocked the phosphorylation of ERK,JNK and p38 MAPK.Conclusions Sil-1 inhib-its the MAPK pathway by blocking the phosphorylation of JNK,ERK,and p38 MAPK,and achieves a protec-tive effect on rats with acute myocardial infarction.
