OBJECTIVE To investigate the efficacy and safety of ivabradine in the treatment of end-stage renal disease patients with chronic heart failure （CHF） during maintenance hemodialysis （MHD）. METHODS End-stage renal disease patients with CHF during MHD who were treated in our hospital from May 2021 to September 2023 and met the inclusion criteria were selected as the study subjects. They were randomly divided into control group and observation group， with 60 cases in each group， using a random number table method. Both groups of patients received MHD three times a week for 4 hours each time and were anticoagulated with low-molecular weight heparin sodium. At the same time， they were treated with CHF conventional therapy； based on the above treatment， observation group was orally administered Ivabradine tablets 5 mg， twice a day （if the resting heart rate was above 60 beats/min after 2 weeks， the drug dose was increased to 7.5 mg， twice a day）. Both groups of patients were treated continuously for 6 months. The clinical efficacy of 2 groups was compared as well as vital signs， cardiac function， the levels of heart failure- related biomarkers and inflammatory factors before and after treatment， and the incidences of dialysis-related hypotension and adverse drug reactions. RESULTS The effective rate of the observation group （92.45%） was significantly higher than that of the control group （76.47%）， and the incidence of dialysis-related hypotension （20.75%） was significantly lower than that of the control group （41.18%） （P＜0.05）. The heart rate， the levels of left ventricular end-systolic diameter， left ventricular end-diastolic diameter， serum N-terminal pro-B-type natriuretic peptide， cancer antigen 125， tumor necrosis factor-α， interleukin-6， and hypersensitive C-reactive protein in observation group after treatment were significantly lower than those of control group （P＜0.05）； the left ventricular ejection fraction and cardiac output were significantly higher than those in the control group （P＜0.05）. There was no statistically significant difference in the diastolic blood pressure， systolic blood pressure， or the total incidence of adverse drug reactions between the two groups after treatment （P＞0.05）. CONCLUSIONS Ivabradine can significantly improve cardiac function， inhibit ventricular remodeling， down-regulate serum levels of serum N-terminal pro-B-type natriuretic peptide and cancer antigen 125， decrease body inflammation levels and the incidence of dialysis-related hypotension in end-stage renal disease patients with CHF during MHD， with significant clinical effects and good safety.

The innate immune system can be boosted in response to subsequent triggers by pre-exposure to microbes or microbial products, known as “trained immunity”. Compared to classical immune memory, innate trained immunity has several different features. Firstly, the molecules involved in trained immunity differ from those involved in classical immune memory. Innate trained immunity mainly involves innate immune cells (e.g., myeloid immune cells, natural killer cells, innate lymphoid cells) and their effector molecules (e.g., pattern recognition receptor (PRR), various cytokines), as well as some kinds of non-immune cells (e.g., microglial cells). Secondly, the increased responsiveness to secondary stimuli during innate trained immunity is not specific to a particular pathogen, but influences epigenetic reprogramming in the cell through signaling pathways, leading to the sustained changes in genes transcriptional process, which ultimately affects cellular physiology without permanent genetic changes (e.g., mutations or recombination). Finally, innate trained immunity relies on an altered functional state of innate immune cells that could persist for weeks to months after initial stimulus removal. An appropriate inducer could induce trained immunity in innate lymphocytes, such as exogenous stimulants (including vaccines) and endogenous stimulants, which was firstly discovered in bone marrow derived immune cells. However, mature bone marrow derived immune cells are short-lived cells, that may not be able to transmit memory phenotypes to their offspring and provide long-term protection. Therefore, trained immunity is more likely to be relied on long-lived cells, such as epithelial stem cells, mesenchymal stromal cells and non-immune cells such as fibroblasts. Epigenetic reprogramming is one of the key molecular mechanisms that induces trained immunity, including DNA modifications, non-coding RNAs, histone modifications and chromatin remodeling. In addition to epigenetic reprogramming, different cellular metabolic pathways are involved in the regulation of innate trained immunity, including aerobic glycolysis, glutamine catabolism, cholesterol metabolism and fatty acid synthesis, through a series of intracellular cascade responses triggered by the recognition of PRR specific ligands. In the view of evolutionary, trained immunity is beneficial in enhancing protection against secondary infections with an induction in the evolutionary protective process against infections. Therefore, innate trained immunity plays an important role in therapy against diseases such as tumors and infections, which has signature therapeutic effects in these diseases. In organ transplantation, trained immunity has been associated with acute rejection, which prolongs the survival of allografts. However, trained immunity is not always protective but pathological in some cases, and dysregulated trained immunity contributes to the development of inflammatory and autoimmune diseases. Trained immunity provides a novel form of immune memory, but when inappropriately activated, may lead to an attack on tissues, causing autoinflammation. In autoimmune diseases such as rheumatoid arthritis and atherosclerosis, trained immunity may lead to enhance inflammation and tissue lesion in diseased regions. In Alzheimer’s disease and Parkinson’s disease, trained immunity may lead to over-activation of microglial cells, triggering neuroinflammation even nerve injury. This paper summarizes the basis and mechanisms of innate trained immunity, including the different cell types involved, the impacts on diseases and the effects as a therapeutic strategy to provide novel ideas for different diseases.

Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

OBJECTIVE To investigate the effects and mechanism of asperuloside （Asp） on the pyroptosis of intestinal epithelial cells in rats with ulcerative colitis （UC）. METHODS The male SD rats were randomly divided into Control group， model group （UC group）， ASP low-dose and high-dose groups [Asp-L， Asp-H groups， Asp 35， 70 mg/（kg·d）]， ASP high-dose group+AMPK inhibitor Compound C group [Asp-H+Compound C group， Asp 70 mg/（kg·d）+Compound C 0.2 mg/（kg·d）]， with 12 rats in each group. Except for Control group， the other groups were injected with 50% ethanol （0.25 mL）+5% 2，4， 6- trinitrobenzene sulfonic acid solution （2 mL/kg） into the intestinal cavity to construct UC model. After modeling， the rats in each drug group were given corresponding drug solution by gavage or （and） tail vein injection， once a day， for 14 consecutive days. After the last administration， the weight of rats in each group was measured， and the length of their colons was measured； disease activity index （DAI） score and colonic mucosal damage index （CMDI） score were performed， and the serum levels of inflammatory factors （interleukin-18， -1β， -6） were detected. The pathological changes of the colon tissue were observed. The expressions of pyroptosis-related proteins [caspase-1， gasdermin D （GSDMD）] in colon tissue， and pathway-related proteins such as adenosine monophosphate-activated protein kinase （AMPK）， thioredoxin-interacting protein （TXNIP）， NOD-like receptor protein 3 （NLRP3） and apoptosis-associated speck-like protein containing a CARD （ASC） were all detected. RESULTS Compared with Control group， the colon tissue structure of rats in UC group was damaged， with obvious infiltration of inflammatory cells and edema. Their body weight， colon length and phosphorylation level of AMPK protein were significantly reduced or shortened； DAI and CMDI scores， serum levels of inflammatory factors， and the protein expressions of caspase-1， GSDMD， TXNIP， NLRP3 and ASC in colon tissue were increased or upregulated significantly （P＜0.05）. Compared with UC group， the pathological damage of colon tissue in rats was relieved in Asp-L and Asp-H groups， and all quantitative indicators were significantly improved （P＜0.05）； the improvement effect of Asp-H group was more significant （P＜0.05）. Compound C could significantly reverse the improvement effect of high-dose of Asp on the above indicators in UC rats （P＜0.05）. CONCLUSIONS Asp can improve inflammatory damage in colon tissue and inhibit pyroptosis of intestinal epithelial cells in UC rats， which is associated with the activation of AMPK and inhibition of TXNIP/NLRP3 signaling pathway.

With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.

ObjectiveTo explore effect of Xianlian Jiedu prescription on the recurrence of colorectal cancer （CRC） and investigate the related mechanisms. MethodsA postoperative recurrence model was established in 25 Balb/c mice by injecting CT26 cells subcutaneously into the armpit， followed by surgical removal of 99% of the subcutaneous tumor. The mice were randomly divided into model group， low-dose Xianlian Jiedu prescription （XLJDP-L） group （6.45 g·kg^-1·d^-1）， medium-dose Xianlian Jiedu prescription （XLJDP-M） group （12.9 g·kg^-1·d^-1）， high-dose Xianlian Jiedu prescription （XLJDP-H） group （25.8 g·kg^-1·d^-1）， and 5-fluorouracil （5-FU） group （1×10^-3 g·kg^-1·d^-1）. The mice were euthanized after 14 days of continuous intervention， and recurrent tumor tissue was harvested. Hematoxylin and eosin （HE） staining was used to observe pathological and morphological changes in the recurrent tumor tissue. Immunohistochemistry （IHC） was employed to assess the expression of proliferating cell nuclear antigen （Ki67）， vascular endothelial growth factor （VEGF）， and platelet-endothelial cell adhesion molecule （CD31） in recurrent tumor tissue. The Western blot was used to detect the protein expression levels of angiopoietin-2 （ANG-2）， VEGF， phosphorylated-protein kinase B （p-Akt）， protein kinase B （Akt）， phosphorylated-phosphatidylinositol 3-kinase （p-PI3K）， and phosphatidylinositol 3-kinase （PI3K） in recurrent tumor tissue. ResultsBefore treatment， there were no statistical differences in tumor volume， tumor weight， and body mass among the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group compared to the model group， indicating model stability. After treatment， compared with those in the model group， the tumor volume and tumor weight in the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly reduced （P<0.01）， showing dose dependency. Meanwhile， there were no significant differences in body weight among the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group compared to the model group. HE staining showed that compared with that in the model group， tumor tissue in the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group had loosely arranged cells， increased intercellular spaces， small and shriveled nuclei， light staining， fewer mitotic figures and atypical nuclei， and increased necrotic areas. IHC showed that compared with those of the model group， the positive rates of Ki67， VEGF， and CD31 in the recurrent tumor tissue of the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly reduced （P<0.01） in a dose-dependent manner. Western blot results showed that compared with those of the model group， the protein expression levels of ANG-2 and VEGF in the recurrent tumor tissue of the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly downregulated （P<0.05， P<0.01）， and the p-Akt/Akt and p-PI3K/PI3K ratios were significantly decreased in a dose-dependent manner （P<0.05， P<0.01）. ConclusionXianlian Jiedu prescription significantly inhibits the recurrence of CRC in mice after subcutaneous tumor surgery. The mechanism may involve regulating the PI3K/Akt pathway and downregulating key angiogenic proteins such as ANG-2， VEGF， and CD31.

Serine protease inhibitor Kazal-type (SPINK) is a skin keratinizing protease inhibitor, which was initially found in animal serum and is widely present in plants, animals, bacteria, and viruses, and they act as key regulators of skin keratinizing proteases and are involved in the regulation of keratinocyte proliferation and inflammation, primarily through the inhibition of deregulated tissue kinin-releasing enzymes (KLKs) in skin response. This process plays a crucial role in alleviating various skin problems caused by hyperkeratinization and inflammation, and can greatly improve the overall condition of the skin. Specifically, the different members of the SPINK family, such as SPINK5, SPINK6, SPINK7, and SPINK9, each have unique biological functions and mechanisms of action. The existence of these members demonstrates the diversity and complexity of skin health and disease. First, SPINK5 mutations are closely associated with the development of various skin diseases, such as Netherton’s syndrome and atopic dermatitis, and SPINK5 is able to inhibit the activation of the STAT3 signaling pathway, thereby effectively preventing the metastasis of melanoma cells, which is important in preventing the invasion and migration of malignant tumors. Secondly, SPINK6 is mainly distributed in the epidermis and contains lysine and glutamate residues, which can act as a substrate for epidermal transglutaminase to maintain the normal structure and function of the skin. In addition, SPINK6 can activate the intracellular ERK1/2 and AKT signaling pathways through the activation of epidermal growth factor receptor and protease receptor-2 (EphA2), which can promote the migration of melanoma cells, and SPINK6 further deepens its role in stimulating the migration of malignant tumor cells by inhibiting the activation of STAT3 signaling pathway. This process further deepens its potential impact in stimulating tumor invasive migration. Furthermore, SPINK7 plays a role in the pathology of some inflammatory skin diseases, and is likely to be an important factor contributing to the exacerbation of skin diseases by promoting aberrant proliferation of keratinocytes and local inflammatory responses. Finally, SPINK9 can induce cell migration and promote skin wound healing by activating purinergic receptor 2 (P2R) to induce phosphorylation of epidermal growth factor and further activating the downstream ERK1/2 signaling pathway. In addition, SPINK9 also plays an antimicrobial role, preventing the interference of some pathogenic microorganisms. Taken as a whole, some members of the SPINK family may be potential targets for the treatment of dermatological disorders by regulating multiple biological processes such as keratinization metabolism and immuno-inflammatory processes in the skin. The development of drugs such as small molecule inhibitors and monoclonal antibodies has great potential for the treatment of dermatologic diseases, and future research on SPINK will help to gain a deeper understanding of the physiopathologic processes of the skin. Through its functions and regulatory mechanisms, the formation and maintenance of the skin barrier and the occurrence and development of inflammatory responses can be better understood, which will provide novel ideas and methods for the prevention and treatment of skin diseases.

Objective : To investigate the biomechanical effect of alveolar bone graft (ABG) resorption on the maxillary alveolar process under occlusal force in a patient with unilateral cleft lip and palate (UCLP) and provide evidence for the clinical application of ABG. Methods: A 3D finite element maxillary model of an 11-year-old female patient with UCLP was generated. The occlusal force was applied to six models with different ABG resorption, namely non-resorption, upper 1/3 resorption, upper 2/3 resorption, lower 1/3 resorption, lower 2/3 resorption, and upper&lower 1/3 resorption. The properties of structures in all models were set to be linear, elastic, and isotropic. The displacement and Von Mises stress of each reference node of the alveolar process were compared and analyzed. Results: Under occlusal force, the most significant displacement of the alveolar process was located in the anterior area, and it decreased gradually from anterior area to both sides in all groups. The displacement values of the alveolar process under cleft side lateral occlusion were as follows: non-resorption group < lower 2/3 resorption group < upper&lower 1/3 resorption group < lower 1/3 resorption group < upper 2/3 resorption group < upper 1/3 resorption group. The displacement values of the alveolar process under centric occlusion were as follows: non-resorption group < lower 1/3 resorption group < upper&lower 1/3 resorption group < upper 2/3 resorption group < lower 2/3 resorption group < upper 1/3 resorption group. The displacement values of the alveolar process under non-cleft side lateral occlusion were as follows: non-resorption group < lower 1/3 resorption group < upper 1/3 resorption group < lower 2/3 resorption group < upper&lower 1/3 resorption group < upper 2/3 resorption group. The stress was concentrated on the premolar area on the functional side of the alveolar process, followed by the canine and molar areas in all groups. The stress values of the alveolar process under cleft side lateral occlusion were as follows: non-resorption group < lower 2/3 resorption group < upper&lower 1/3 resorption group < upper 2/3 resorption group < lower 1/3 resorption group < upper 1/3 resorption group. The stress values of the alveolar process under centric occlusion were as follows: non-resorption group < upper 1/3 resorption group < lower 1/3 resorption group < lower 2/3 resorption group < upper&lower 1/3 resorption group < upper 2/3 resorption group. The stress values of the alveolar process under non-cleft side lateral occlusion were as follows: non-resorption group < lower 2/3 resorption group < upper&lower 1/3 resorption group < lower 1/3 resorption group < upper 2/3 resorption group < upper 1/3 resorption group. Under occlusal force, the displacement and stress of the alveolar process in the non-resorption model were significantly lower than those in other models. The displacement and stress of the alveolar process in the models with resorption in the lower area of the ABG were significantly lower than those in the models with resorption in the upper-middle areas of the ABG. Conclusion After unilateral complete cleft lip and palate bone grafting, the integrity and continuity of the middle and upper parts of the alveolar process bone grafting play a key role in the biomechanical status of the alveolar process. If bone resorption occurs in the above parts, bone grafting should be considered.
