ObjectiveTo investigate the effect and potential mechanism of caffeic acid (CA) on severe acute pancreatitis (SAP) induced by caerulein combined with lipopolysaccharide (LPS), and to provide a basis for the research on novel drugs for the treatment of SAP. MethodsC57BL/6J mice, aged 6 weeks, were divided into control group, model group, CA group, and octreotide acetate (OA) group, with 6 mice in each group. The mice in the control group were given injection of normal saline, and those in the other groups were given intraperitoneal injection of caerulein combined with LPS to establish a mouse model of SAP. At 1 hour after the first injection of caerulein, the mice in the CA group and the OA group were given intraperitoneal injection of CA or subcutaneous injection of OA at an interval of 8 hours. The general status of the mice was observed after 24 hours of modeling, and serum, pancreas, lung, and colon samples were collected. HE staining was used to observe the histopathological changes of the pancreas and lungs, and the serum levels of α-amylase, lipase, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), alanine aminotransferase, aspartate aminotransferase, and creatinine were measured. RT-PCR was used to measure the expression of proinflammatory factors in the pancreas and lungs; myeloperoxidase (MPO) immunohistochemistry was used to observe the degree of neutrophil infiltration; Western blot was used to measure the activation of nuclear factor-kappa B (NF-κB) and the level of citrullinated histone H3 (CitH3), a marker for the formation of neutrophil extracellular traps (NETs), in the pancreas and lungs, as well as the expression level of ZO-1 in colon tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the Dunnett’s t-test was used for further comparison between two groups. ResultsCompared with the control group, the model group had severe injury in the pancreas and lungs and significant increases in the activity of serum α- amylase and lipase and the levels of the proinflammatory cytokines IL-6, interleukin-1β (IL-1β), and TNF-α in serum and lung tissue (all P<0.05), as well as significant increases in NF-κB activation, neutrophil infiltration, and the formation of NETs in the pancreas and lungs (all P<0.05). Compared with the model group, the CA group had alleviated pathological injury of the pancreas and lungs and significant reductions in the activity of serum α-amylase and the levels of the proinflammatory cytokines IL-6, IL-1β, and TNF-α in serum and lung tissue (all P<0.05), as well as significant reductions in NF-κB activation, neutrophil infiltration, and the formation of NETs in the pancreas and lungs (all P<0.05). ConclusionCA can alleviate SAP induced by caerulein combined with LPS in mice, possibly by inhibiting neutrophil recruitment and the formation of NETs.

Traditional four examinations of traditional Chinese medicine (TCM) are based on the symptoms and signs of patients, which are the advantages of TCM but also have shortcomings. Chronic kidney disease has the characteristics of insidiousness, long-term, deficiency and variability during its onset, which are difficult to be intervened in time based on only symptoms, therefore it is necessary to extend the application of the four examinations in the diagnosis and treatment process of chronic kidney disease. Based on the background of the continuous development of TCM syndrome differentiation techniques, this article proposed the extension and application strategies of the traditional four examinations in chronic kidney disease, including the incorporation of microscopic syndrome differentiation to identify the causes of kidney disease and prevent symptom deterioration; the utilization of accurate examination information enhanced by artificial intelligence for controlling development of existing disease; the integration of disease differentiation and syndrome differentiation to summarize clinical rules towards using constant to measure variation; and the establishment of a kidney disease database for the storage of four examinations information to prevent recurrence after recovery. The four above extension and application strategies can be used to achieve the long-term management and treatment effects of timely and early diagnosis, dynamic observation of the condition, accurate application of intervention, and strengthened prognosis assessment in the diagnosis and treatment of chronic kidney disease, and expand the advantages of TCM in the prevention and treatment of chronic kidney disease.

Breast cancer (BC) is one of the most prevalent malignant tumors affecting women worldwide, with its incidence rate continuously increasing. As a result, treatment strategies for this disease have received considerable attention. Research has highlighted the crucial role of the Hedgehog (Hh) signaling pathway in the initiation and progression of BC, particularly in promoting tumor growth and metastasis. Therefore, molecular targets within this pathway represent promising opportunities for the development of novel BC therapies. This study aims to elucidate the therapeutic mechanisms by which natural compounds modulate the Hh signaling pathway in BC. By conducting a comprehensive review of various natural compounds, including polyphenols, terpenes, and alkaloids, we reveal both common and unique regulatory mechanisms that influence this pathway. This investigation represents the first comprehensive analysis of five distinct mechanisms through which natural compounds modulate key molecules within the Hh pathway and their impact on the aggressive behaviors of BC. Furthermore, by exploring the structure-activity relationships between these compounds and their molecular targets, we shed light on the specific structural features that enable natural compounds to interact with various components of the Hh pathway. These novel insights contribute to advancing the development and clinical application of natural compound-based therapeutics. Our thorough review not only lays the groundwork for exploring innovative BC treatments but also opens new avenues for leveraging natural compounds in cancer therapy.

Soil cadmium pollution can adversely affect the cultivation of the ornamental plant, Coleus scutellarioides. Upon cadmium contamination of the soil, the growth of C. scutellarioides is impeded, and it may even succumb to the toxic accumulation of cadmium. In this study, we investigated the effects of arbuscular mycorrhizal fungi (AMF) on the adaptation of C. scutellarioides to cadmium stress, by measuring the physiological metabolism and the degree of root damage of C. scutellarioides, with Aspergillus oryzae as the test fungi. The results indicated that cadmium stress increased the activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and the content of malondialdehyde (MDA) and proline (Pro) within the cells of C. scutellarioides, but inhibited mycorrhizal infestation rate, root vigour and growth rate to a great degree. With the same cadmium concentration, the inoculation of AMF significantly improved the physiological indexes of C. scutellarioides. The maximum decrease of MDA content was 42.16%, and the content of secondary metabolites rosemarinic acid and anthocyanosides could be increased by up to 27.43% and 25.72%, respectively. Meanwhile, the increase of root vigour was as high as 35.35%, and the DNA damage of the root system was obviously repaired. In conclusion, the inoculation of AMF can promote the accumulation of secondary metabolites, alleviate root damage, and enhance the tolerance to cadmium stress in C. scutellarioides.

To investigate the clinical value of cardiac magnetic resonance feature tracking (CMR-FT) technology in the assessment of the right ventricle function in patients with immune checkpoint inhibitor (ICIs)-related myocarditis. Patients who visited Peking Union Medical College Hospital from April 2022 to April 2024, were diagnosed as ICIs-related myocarditis by cardiologists, and had normal right ventricular ejection fraction (RVEF) were enrolled in myocarditis group. Meanwhile, healthy individuals without cardiovascular diseases were selected as healthy control group. All subjects underwent cardiac magnetic resonance (CMR) examinations. Cardiac function parameters of the left and right ventricles were measured in the subjects, including left ventricular ejection fraction (LVEF), RVEF, left ventricular end-systolic volume index (LVESVI), left ventricular end-diastolic volume index (LVEDVI), right ventricular end-systolic volume index (RVESVI), and right ventricular end-diastolic volume index (RVEDVI). Additionally, myocardial strain of the left and right ventricles were recorded, encompassing left ventricular global longitudinal strain (LV-GLS), left ventricular global circumferential strain (LV-GCS), left ventricular global radial strain (LV-GRS), right ventricular global longitudinal strain (RV-GLS), right ventricular global circumferential strain (RV-GCS), and right ventricular global radial strain (RV-GRS). A total of 30 patients were induded in the myocarditis group and 20 in the healthy control group. The LVEF in the myocarditis group was was lower than that in the control group [(58.0±6.9)% Right ventricular myocardial strain obtained through CMR-FT technology can reveal early right ventricular cardiac dysfunction in patients with ICIs-related myocarditis, providing crucial evidence for early clinical prevention and timely intervention.

Aortic aneurysm and dissection are critical cardiovascular diseases that threaten human life and health seriously. No pharmacological treatment can effectively prevent disease progression. The imbalance of aortic wall cells and non-cellular components leads to structural or functional degeneration of the aorta, which is a prerequisite for disease occurrence. As the important non-cellular component, extracellular matrix (ECM) is crucial to maintain the aortic structure, function, and homeostasis. Abnormal production of elastin and collagen, destruction of cross-linking between elastic fibers and collagen fibers, and the imbalance of metalloproteinase and inhibitors leads to excessive degradation of ECM proteins, all of which have destroyed the structure and function of aorta. It will provide more ideas for disease prevention and treatment by learning ECM proteins and their metabolic mechanism. Here, we focus on the ECM proteins that have been reported to be involved in aortic aneurysm and dissection, and discuss the regulatory mechanism of metalloproteinase and inhibitors.
