In March 2024, organized by Chinese Society of Parenteral and Enteral Nutrition (CSPEN), experts in the fields of general surgery, critical care medicine, gastroenterology, geriatrics, clinical nutrition, clinical pharmacy and evidence-based medicine developed the guidelines for the clinical application of micronutrients in Chinese adult patients (2024 edition) on the basis of latest clinical evidence. The guidelines is of great value in guiding the clinical application of micronutrients. Here, we intended to interpret the guidelines, summarize the differences between domestic and foreign guidelines, and thus enhance our understanding.

Whole-course nutrition management embodies a systematic, dynamic, and individualized approach to precise nutrition management, which could potentially improve patient outcomes. Artificial intelligence has seen advances in the application in medical settings, including nutrition, and its disruptive technology enables the optimization of nutrition management. The nutrition management modality augmented by artificial intelligence to some extent meets the need of comprehensive, dynamic, individualized, and precise nutrition management throughout the whole continuum. It not only facilitates nutrition screening and evaluation, nutritional diagnosis, and individualized treatment regimens, but also allows nutritional monitoring and corresponding dynamic adjustments for optimal nutritional treatment, to improve clinical outcomes. Our aim is to investigate the application and significance of artificial intelligence in the whole-course nutrition management.

Under the background of high-intensity fattening,probiotics have gradually become wide-ly used feed additives.It can inhibit the proliferation of pathogenic bacteria,maintain the microeco-logical balance in the digestive tract,and improve the host immune function.In order to screen lac-tic acid bacteria strains with potential probiotic effects,23 acid-producing strains were isolated from rumen fluid of healthy Duolang sheep by CaCO3-MRS solid medium.Safe strains were re-screened through primary screening and hemolysis tests.Acid tolerance tests and bile salt tests were used to screen the strains that were relatively adapted to the rumen environment.The survival rate of the strain M2 was 93.80％under pH3.0 and 59.72％under bile salt concentration of 0.30％and the survival rate is higher than other strains under high temperature conditions.Subsequently,morphological observation,molecular biological identification,testing of pathogen antagonism,antibiotic tolerance analysis,growth characteristics detection and other methods were used to fur-ther explore the characteristics of the strain.The results showed that the strain to be tested was Gram-positive bacillus.After 16S rRNA gene sequence comparison,the strain was identified as Lactobac illus salivus,which could be used as a candidate strain to develop probiotics.The research results laid a foundation for its application in Duolang sheep breeding.

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.

In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

Most hospitalized patients infected with coronavirus disease 2019 (COVID-19) are in severe or critical condition, and malnutrition is a key factor contributing to adverse outcomes. The basic principles of medical nutrition therapy have been determined in the recently released tenth edition of the National Diagnosis and Treatment Protocol. The principles have promoted nutritional risk assessment, emphasized the preferred method of enteral nutrition, and recommended the daily intake of calories at 25 to 30 kcal/kg and protein at > 1.2g/kg. Parenteral nutrition should be also added when necessary. Based on the above principles, Beijing Hospital has refined the medical nutrition therapy measures to facilitate the implementation in clinical practice, in order to improve healthcare quality and decrease the mortality in COVID-19 patients.
