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.

Dry eye disease (DED) is a prevalent and intractable ocular disease induced by a variety of causes. Elevated sphingomyelin (SM) levels and pro-inflammatory cytokines were detected on the ocular surface of DED patients, particularly in the meibomian glands. Sphingomyelin synthase 2 (SMS2), one of the proteins involved in SM synthesis, would light a novel way of developing a DED therapy strategy. Herein, we report the design and optimization of a series of novel thiophene carboxamide derivatives to afford 14l with an improved highly potent inhibitory activity on SM synthesis (IC_{50, SMS2} = 28 nmol/L). Moreover, 14l exhibited a notable protective effect of anti-inflammation and anti-apoptosis on human corneal epithelial cells (HCEC) under TNF-α-hyperosmotic stress conditions in vitro, with an acceptable ocular specific distribution (corneas and meibomian glands) and pharmacokinetics (PK) profiles (t _{1/2, cornea} = 1.11 h; t _{1/2, meibomian glands} = 4.32 h) in rats. Furthermore, 14l alleviated the dry eye symptoms including corneal fluorescein staining scores and tear secretion in a dose-dependent manner in mice. Mechanically, 14l reduced the mRNA expression of Tnf-α, Il-1β and Mmp-9 in corneas, as well as the proportion of very long chain SM in meibomian glands. Our findings provide a new strategy for DED therapy based on selective SMS2 inhibitors.

Objective To explore the relevant factors affecting the efficacy of traditional Chinese medicine in treating MG,and to develop and validate a nomogram model,in order to personalize the prediction of the probability of benefits for MG patients after traditional Chinese medicine treatment,further guide clinical physicians in targeted medication,and provide guidance for the traditional Chinese medicine treatment of MG.Method Retrospective analysis of MG patients who visited the Affiliated Hospital of Changchun University of Traditional Chinese Medicine from March 2018 to June 2022,13 clinical factors were selected to evaluate the results.To acquire independent factors,univariate and multivariate Logistic analyses were performed.The area under the receiver operating characteristic curve,Harrell's concordance index,calibration curve,and decision curve analyses were used to evaluate the predictive ability,accuracy,and clinical practicability of the prediction model.Results A total of 204 cases were included,divided into derivation cohort 139 cases and temporal validation cohort 65 cases.Multivariate Logistic regression showed 4 independent predictors affecting effectiveness of traditional Chinese medicine in treating MG,including age at onset,repetitive nerve stimulation positive,oral immunosuppressant and anxiety/depression.AUC values for the model group and validation group were 0.76(95%CI:0.68-0.84)and 0.83(95%CI:0.71-0.95),respectively,and based on calibration curve and decision curve analysis,we concluded that the nomogram showed excellent performance.Conclusion MG patients may experience a decrease in short-term efficacy with age,positive RNS,concomitant emotional abnormalities,or recent history of immunosuppressive therapy.This nomogram effectively predicts the possibility of short-term effective traditional Chinese medicine treatment in MG patients.

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.

Diseases of ocular fundus are the leading causes of severe vision impairment or even blindness in patients worldwide, and the medical treatments are seriously limited by the difficulty of therapeutic drugs entering the fundus due to the various physiological barriers. Nano-drug delivery systems, with their nanoscale size and large surface area, can be loaded with therapeutic drugs of different physicochemical properties and modified with various surface active substances, which can not only improve the solubility and penetration of the drugs, but also protect biologic drugs from degradation and improve the biological safety and bioavailability, as well as deliver therapeutic drugs to specific ocular targets. All of these make the therapeutic potential enormous. Currently, more and more studies have been carried out to take advantage of nanomaterials for the treatment of different fundus diseases, including neurodegenerative diseases, fundus neovascularization, endophthalmitis and fundus tumors. This review analyzes the challenges and barriers faced by different routes of drug administration in the treatment of fundus diseases, the physicochemical properties of common nano-drug delivery systems that have been studied in related fields, and further summarizes the progress, advantages, limitations, and future directions of the application of various nano-drug delivery systems for the treatment of ocular fundus diseases in recent years.
