Objective:To explore the molecular mechanism of TCM compound Shengxue Tongbian Granules in improving intestinal injury in septic rats through bioinformatics and experimental validation methods.Methods:The GSE131761 gene set was processed by bioinformatics to screen differential genes, then weighted gene co-expression network analysis (WGCNA) was applied to screen modular genes. The intersection of modular genes and differential genes was taken, and finally, the least absolute shrinkage and selection operator (LASSO) technique was applied to further obtain the key targets of sepsis, which was validated by experiments. Totally 72 SD rats were divided into sham-operation group, model group, dexamethasone group (0.15 mg/kg), Shengxue Tongbian Granules low- (0.3 g/kg), medium- (0.6 g/kg), and high-dosage (1.2 g/kg) groups, with 12 rats in each group. Corresponding drug interventions were administered to each treatment group before and 12 hours after modeling. The sham-operation group and the model group were gavaged daily with equal amounts of saline. Samples were collected after 24 hours. HE staining was used to detect the pathological morphology of intestinal tissues in each group of rats; ELISA was used to detect the levels of TNF-α, diamine oxidase (DAO), IL-6, IL-10, and myeloperoxidase (MPO) in rat serum. Immunohistochemistry was used to detect the protein expressions of MPO and neutrophil elastase (NE/LANE) in intestinal tissue, and Western blot was used to detect the protein expression of peptidyl arginine deaminase (PAD4) in intestinal tissue.Results:Seven final key genes related to sepsis were selected, namely ANXA3, CYP1B1, FCAR, LILRA5, PADI4, NOV, and S100A12. Experimental results showed that drug administration alleviated intestinal injury; compared with the model group, the levels of TNF-α, IL-6, MPO, and DAO decreased in the Shengxue Tongbian Granules high-dosage group ( P<0.05), the levels of ELANE and MPO were reduced in Shengxue Tongbian Granules low-, medium-, and high-dosage groups ( P<0.05), and PAD4 expression was reduced in the Shengxue Tongbian Granules high-dosage group ( P<0.05). Conclusion:Shengxue Tongbian Granules can improve the intestinal injury of septic rats, and the mechanism may be related to the inhibition of PAD4-mediated formation of NETs and the improvement of inflammatory response.

Spleen-stomach damp-heat syndrome is currently the most prevalent TCM pattern in patients with chronic atrophic gastritis (CAG), with internal damp-heat accumulation regarded as a key factor contributing to its prolonged and refractory course. This syndrome represents a critical stage in the progressive pathogenesis of CAG, characterized by a deepening pathological evolution. Modern TCM practitioners generally agree that its core pathogenesis lies in "deficiency in root and excess in superficiality, with internal damp-heat retention", and emphasize a treatment strategy that combines eliminating pathogenic factors and reinforcing the body's healthy qi through dynamic syndrome differentiation. Chinese materia medica used in treating CAG with spleen-stomach damp-heat syndrome can effectively relieve clinical symptoms, improve the internal damp-heat environment, mitigate gastric mucosal atrophy and intestinal metaplasia, and delay the inflammation-to-cancer transformation. Its mechanisms may involve eradication of Helicobacter pylori, repair of gastric mucosal injury, regulation of immune inflammatory response and other aspects, which has the advantages of multi-channel and multi-target.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Objective:To explore the views of adolescents with asthma on factors affecting disease self-management, so as to provide a basis for improving self-management of asthma children, and propose improvement suggestions.Methods:This study was a descriptive qualitative study. From February to June 2023, 10 to 17 year old children with asthma were recruited at the Asthma Clinic of the Children's Hospital affiliated to Capital Institute of Pediatrics through purposive sampling. One-on-one semi-structured interviews were conducted around self-management and its related factors, and the thematic analysis was used to analyse interview materials.Results:A total of 17 adolescents with asthma, aged (13.00±2.03) years, with a course of disease of (5.00±2.85) years, were included. The interview materials included two aspects, namely facilitators and barriers of self-management. The facilitators were coded into three themes and seven sub-themes, including the individual management awareness of children with asthma (sense of responsibility, compliance awareness), social support (parental care and compensation, teacher and classmate support, patient interaction), and health education (health guidance from doctors and nurses, school health propaganda). Barriers were encoded into three themes and six sub-themes, including disease cognition (demand competition, importance), social environment (interpersonal interaction, physical environment), and healthcare services (accessibility of medical services, school related medical resources) .Conclusions:The self-management of adolescents with asthma is affected by multiple factors. Individual management awareness, social support, and health education can promote self-management in children with asthma, while unfavorable factors in disease cognition, social environment, and healthcare services can hinder self-management in children with asthma. Medical and nursing staff should develop and implement empowerment plans for self-management of asthma children, by mobilizing multi-channel medical resources, providing multi-dimensional full process empowerment, and helping asthma children build a diverse interpersonal support network system, in order to promote effective health management transition for adolescents with asthma.

Pulmonary fibrosis is a respiratory system disorder characterized by damage to alveolar epithelial cells,pathological proliferation and transformation of fibroblasts,excessive deposition of extracellular matrix,leading to structural damage and loss of function in lung tissues,with a high mortality rate and limited effective treatment methods.This article was based on the TCM understanding of"lung connecting to large intestine",namely the theory of"lung and the large intestine being interior-exterior related",and set the modern medical understanding of"lung connecting to large intestine",namely the theory of"gut-lung axis"as the key.Combining the TCM pathogenesis of pulmonary fibrosis and the related mechanisms of"gut-lung axis"in pulmonary fibrosis,it preliminarily expounded the connotation of TCM regulating the"gut-lung axis"to treat pulmonary fibrosis,aiming to provide new ideas for clinical treatment of pulmonary fibrosis through the"gut-lung axis".

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To explore the risk factors affecting the occurrence of refeeding syndrome in patients with acute pancreatitis,to establish a risk prediction model and verify it,and provide enlightenment for clinical nursing management.Methods A total of 260 patients with acute pancreatitis in our hospital from January 2021 to March 2023 were selected and divided into a refeeding syndrome group and a non-refeeding syndrome group according to whether refeeding syndrome occurred.Logistic regression analysis was performed on the related factors,and the risk model of array diagram was constructed and verified.Results Of the 260 patients with acute pancreatitis,56 developed refeeding syndrome,with an incidence of 21.54%.The results of factor analysis showed that high grade of gastrointestinal function,additional protein supplementation during feeding,NRS score and rapid infusion of nutrient solution were independent risk factors for refeeding syndrome in patients with acute pancreatitis(OR>1,P<0.05).High serum prealbumin concentration before feeding and high serum albumin concentration before feeding were independent protective factors(OR<1,P<0.05).The results of Hosmer-Lemeshow goodness-of-fit test showed that χ2=8.019,P=0.432;the area under the ROC curve was 0.915(P<0.001,95%CI:0.865～0.965);the sensitivity was 83.30%;the specificity was 87.90%;the maximum Youden index was 0.712.The model regression equation Logit(P)=1.899×additional protein supplementation in feeding+1.549×gastrointestinal function classification+0.683×NRS score+0.031×nutrient solution infusion rate-0.018×prefeeding serum albumin-0.038×prefeeding serum albumin-9.836.Conclusion The risk prediction model of refeeding syndrome in patients with acute pancreatitis established in this study has good accuracy and discrimination,which can predict the risk of refeeding syndrome in patients with acute pancreatitis for clinical nursing staff and formulate individualized prevention strategies as soon as possible.
