With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

BACKGROUND:Bone morphogenetic protein 7 is mainly synthesized in the kidney and is expressed at different stages of kidney development,but the spatiotemporal distribution of its expression and its relationship with kidney development have not been systematically reported.OBJECTIVE:To observe the expression of bone morphogenetic protein 7 in mice kidneys during different developmental stages and to explore its potential relationship with kidney development.METHODS:Immunohistochemical techniques combined with stereological methods and western blot analysis were used to observe and analyze the expression of bone morphogenetic protein 7 in mouse kidney tissues at embryonic days(E)12,14,16,18,and neonatal days(N)1,3,7,14,24,40,and 70.RESULTS AND CONCLUSION:(1)The results of immunohistochemistry showed that bone morphogenetic protein 7 was mainly expressed in the nephrogenic zone and immature renal corpuscles during the early stage of kidney development.Subsequently,it was located in mature renal corpuscles and the surrounding distal convoluted tubules,and the expression range gradually increased.After N40 days,bone morphogenetic protein 7 positively expressed in the renal interstitium.(2)Stereology and western blot results showed that the expression level of bone morphogenetic protein 7 gradually decreased with the development of the kidney,reached the lowest level at N7 days,and then slowly increased.To conclude,during the process of kidney development,the expression of bone morphogenetic protein 7 has significant spatiotemporal specificity,and it is hypothesized that it may be related to the development and maturation of renal corpuscles and distal convoluted tubules.

Objective:To explore a systematic training for quick identification for diagnosis and treatment of the causes of reversible cardiac arrest,which was assisted by bedside ultrasound simulator combined with memory mnemonic,so as to improve the treatment skill of physicians for the causes of disease,and enhance the success rate of cardiopulmonary resuscitation.Methods:Thirty clinical resident doctors who were rotating in the emergency intensive care unit(ICU)of Xuanwu Hospital,Capital Medical University,from May 2023 to May 2024 were selected.The bedside ultrasound simulator combined with memory mnemonic was used to simulate training,which can improve the ability of resident doctors in quickly determining the cause of reversible cardiac arrest.The self-made questionnaire was used to investigate the baseline situation of resident doctors before they were trained,and the teaching effectiveness after they received training.After training,the grasping states of resident doctors for the cause of reversible cardiac arrest were detected through 10 kinds of clinical cases included pulmonary embolism,myocardial infarction,aortic dissection,pericardial tamponade,ventricular fibrillation,electrolyte disturbance,hypovolemic shock,tension pneumothorax,poisoning and hypothermia.Results:The duration of quick retelling of resident doctors for the causes of reversible cardiac arrest was(15.07±3.68)s after training,which was lower than(47.27±10.25)s before training,and the difference was significant(t=14.763,P<0.05).The awareness rate of them for the causes of reversible cardiac arrest was 100%after training,which was significantly higher than 3.33%before training,and the difference was significant(x2=56.129,P<0.05).The identification of resident doctor for ultrasonic image was zero basis before training,and the identification rate was 0%.All of resident doctors can achieve 100%identification for routine ultrasound,cardiac arrest,pericardial tamponade and ventricular fibrillation within the simulator after training,and the correct recognition rates of them for pulmonary embolism,tension pneumothorax,acute myocardial infarction and aortic dissection were respectively 86.67%,63.33%,70%and 66.67%.After training,the duration of correct recognition of resident doctors for pulmonary embolism,tension pneumothorax and acute myocardial infarction were respectively(58.77±19.61)s,(69.05±10.47)s and(75.52±10.51)s,all of which were less than the duration of incorrect recognition,and the differences were statistically significant(t=2.153,2.781,2.124,P<0.05).Conclusion:Ultrasound combined with memory mnemonic can help resident doctors to quickly establish the clinical thinking clue about hypoxia,hypovolemia,hypo/hyperkalemia,hypo/hyperthermia,hypo/hyperglycemia,tamponade cardiac,thrombosis pulmonary,thrombosis coronary,toxins,tension pneumothorax(5H5T)for the cause of reversible cardiac arrest,which will contribute to strengthen and improve the practical ability of clinician in quick judgement for reversible etiology.

Angiopoietin-like proteins(ANGPTLs)are a family of proteins that are structurally similar to angio-poietin.So far,eight ANGPTLs have been discovered,namely ANGPTL1 to ANGPTL8.They are not only angiogenic fac-tors,but also play a pivotal role in various pathophysiological processes such as glucose and lipid metabolism,redox regu-lation,chronic inflammation and cancer,and having a close connection with the occurrence and development of metabolic diseases.This review focuses on the mechanism of action of ANGPTLs in metabolic associated fatty liver disease,in order to make a contribution to the prevention and treatment of MAFLD and concurrent diseases.

Medication literacy directly impacts the safety of drug therapy and clinical outcomes.Patients with low medication literacy demonstrate poorer medication adherence,higher medication risks,and inferior disease control outcomes.Chronic disease patients face significant medication safety hazards due to multimorbidity and polypharmacy.Accurately assessing medication literacy can quantify individual medication capabilities and promote safe medication management.This paper reviews the structure,methods,applicable population,current applications,advantages,and limitations of medication literacy assessment tools for chronic disease patients,both domestically and internationally.The aim is to provide references for developing and applying medication literacy assessment tools for patients in China,offering a basis for scientifically evaluating medication literacy levels and formulating medication safety intervention strategies.

Objective:To investigate the awareness of medical staff on pharmacovigilance and the current situation of the construction of pharmacovigilance system in medical institutions.Methods:A self-designed questionnaire was sent to medical institutions in China through Professional Committee on Pharmacovigilance Research, China Society for Drug Regulation in the form of Wechat, and medical staff participated voluntarily. The contents of the questionnaire included 23 questions in 4 dimensions, including the basic information of the respondents, their understanding of the concept and regulations of pharmacovigilance, the management of pharmacovigilance, and the reporting and feedback of adverse drug reactions(ADRs)/events in their medical institutions. The survey time was from August 18, 2023 to October 18, 2023. The data from the questionnaire were analyzed descriptively.Results:The collected questionnaires were from medical institutions in 31 provinces, autonomous regions, and municipalities directly under the central government, with a total of over 100 questionnaires collected in each region. A total of 10 991 medical staff participated in the survey, including 5 504 pharmacists, 2 120 doctors, and 3 367 nurses. Among them, 10 131 (92.18%) respondents had heard of pharmacovigilance, 4 511 (41.04%) had participated in pharmacovigilance-related works, 9 368 respondents (86.41%) answered that the ADRs monitoring and management system had been established in medical institutions where they worked, 8 186 respondents (75.51%) answered that leading group for pharmacovigilance (including ADRs monitoring) had been set up in the medical institutions where they worked, 8 605 respondents (79.37%) answered that the pharmacovigilance works was managed by special personnel in the institutions where they worked, 7 859 (72.49%) answered that there were liaison officers in the clinical departments where they worked, 6 043 (55.74%) answered that the individuals would be rewarded for reporting ADRs, 4 809 (44.36%) answered that pharmacovigilance had been included in the daily works and assessment indicators of the departments, and 5 351 (49.36%) answered that reports of ADRs were reviewed by special personnel. Active reporting by medical staff was the main collection channel of ADRs, 3 391 (31.28%) answered they had actively captured ADRs from the hospital information system, and 7 728 (71.28%) answered they had reported ADRs through the hospital information system, 10 061 (92.81%) answered that the monitoring results of ADRs would be regularly fed back in the hospitals where they worked, and 6 239 (57.55%) answered that regular training on pharmacovigilance for all medical staff would be provided in the institutions where they worked.Conclusions:Medical staff have generally heard of pharmacovigilance and are aware of the national pharmacovigilance system, but they still have insufficient understanding of the concept and regulations of pharmacovigilance. The degree of participating in pharmacovigilance works of medical staff in different regions are different. The monitoring and management of ADRs could be paid attention to in the most medical institutions, but the degree of improvement of pharmacovigilance system in different levels of medical institutions is different.
