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.

OBJECTIVE To evaluate the anticoagulant efficacy and safety of nafamostat mesylate （NM） in the treatment of uremic patients at high risk of bleeding undergoing continuous veno-venous hemofiltration （CVVH） with different methods （pre- dilution and post-dilution）. METHODS A total of 130 uremic patients at high risk of bleeding who underwent CVVH treatment in the nephrology department of Chongqing University Three Gorges Hospital from July 2023 to September 2024 were selected. They were divided into pre-dilution group and post-dilution group according to the random number table method， with 65 cases in each group. Both groups of patients received CVVH treatment under NM anticoagulation. The pre-dilution group adopted the pre-dilution replacement method， while the post-dilution group adopted the post-dilution replacement method. The coagulation， pressure， and usage duration of the filter and dialysis circuit venous reservoirs were compared between the two groups. The changes in prothrombin time （PT）， prothrombin time-international normalized ratio （PT-INR）， activated partial thromboplastin time （APTT）， and fibrinogen （FIB） in the peripheral venous blood before the heparin pump and after the filter at 1， 4 and 7 h of CVVH treatment， as well as 20 min after the end of treatment， were compared between the two groups. The single-compartment urea clearance rate （spKt/V）， β2-microglobulin （β2-MG） clearance rate and the incidence of adverse reactions were duni2007@foxmail.com compared between the two groups. RESULTS Both the pre-dilution and post-dilution groups had 60 patients who completed the study. The incidence of grade Ⅱ-Ⅲ coagulation of the filter and venous reservoirs， as well as the number of patients with transmembrane and venous pressure alarm intervention in the post- dilution group were significantly higher or more than those in the pre-dilution group （P＜0.05）， while usage time of the filter and the pipeline in the post-dilution group was significantly shorter than that in the pre-dilution group （P＜0.05）. The APTT values before the heparin pump as well as PT and APTT values after the filter at 1 h， 4 h， and 7 h of CVVH treatment in the post-dilution group were significantly higher than those in the pre-dilution group （P＜0.001）. There were no significant differences in PT， PT- INR， APTT and FIB between the two groups of patients 20 min after the end of treatment （P＞0.05）. The spKt/v and β2-MG clearance rates in the post-dilution group were significantly higher than those in the pre-dilution group （P＜0.001）. There was no significant difference in the incidence of adverse reactions between the two groups （P＞0.05）. CONCLUSIONS When NM is used as an anticoagulant in the CVVH treatment of uremic patients at high risk of bleeding， compared with the pre-dilution treatment method， the post-dilution treatment method has a higher incidence of filter and dialysis tubing venous reservoir， a shorter usage time of the filter and pipeline， and a greater impact on extracorporeal coagulation， but has a higher solute clearance rate. Clinically， different dilution methods can be selected according to the different treatment needs of patients.

Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10 /L vs preoperative 3.07×10 /L, P<0.001), with significant upregulation of CD11b (7.30×10 /L vs preoperative 3.05×10 /L, P<0.001) and CD54 (7.15×10 /L vs preoperative 2.99×10 /L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10 /L vs preoperative 1.12×10 /L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10 /L vs preoperative 1.12×10 /L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

Irritable bowel syndrome （IBS） is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years， traditional Chinese medicine （TCM） has made progress in multiple aspects of IBS research and treatment， including syndrome distribution， development of TCM formulas， clinical efficacy evaluation， external therapies， and psychosocial regulation. However， it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria， and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment， combining TCM external therapies such as acupuncture， moxibustion and acupoint application）， and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies， artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas， so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

Objective To explore the effectiveness of the cumulative sum (CUSUM) and the exponentially weighted moving average (EWMA) for early warning of influenza epidemic using two datasets of reported influenza cases and influenza-like illness (ILI) cases. Methods Using the reported cases of influenza and ILI in Daxing District, Beijing, from week 23 of 2018 to week 22 of 2024 as data sets, the CUSUM and EWMA models were established, respectively. The positive rate of influenza etiology was used as the ^“gold standard^”, and the Youden index was used as the evaluation index to compare the early warning effect of the two models under different data sets and different parameters. Results In CUSUM, the optimal Youden indices of the reported influenza cases set and the ILI cases set were 0.751 and 0.635, respectively. In EWMA, the optimal Youden indices of the reported influenza cases set and the ILI cases set were 0.544 and 0.464, respectively. The optimal EWMA and CUSUM models could both issue early warning signals in advance of the ^“gold standard^”. Conclusion In the influenza epidemic early warning in Daxing District, Beijing, the CUSUM model established with the reported cases of influenza can achieve good early warning effects, but the model parameters need to be dynamically adjusted according to the local epidemic characteristics.

OBJECTIVE To observe the clinical efficacy of mycophenolate mofetil （MMF） combined with Budesonide enteric capsules in the treatment of high-risk progressive immunoglobulin A nephropathy （IgAN）. METHODS A total of 150 adult patients with high-risk progressive IgAN who attended the Department of Nephrology， Chongqing University Three Gorges Hospital， between August 1， 2024 and March 1， 2025 were enrolled in this study. The control group （ n ＝94） received MMF combined with glucocorticoid， while the observation group （ n ＝56） received MMF combined with Budesonide enteric capsules. The 24-hour urine protein （24 h UP）， estimated glomerular filtration rate （eGFR）， and albumin （ALB） levels of patients in both groups were compared at 1， 2， 3， and 6 months post-treatment. The complete response （CR） rate and overall response rate were calculated for both groups at 1， 2， 3， and 6 months post-treatment. Adverse reactions occurring during treatment were compared between the two groups. RESULTS Compared with before treatment， 24 h UP decreased significantly in both groups at different time points after treatment （ P ＜0.05）， and ALB increased significantly （ P ＜0.05）. However， there was no significant change in eGFR （ P ＞0.05）. The 24 h UP in the observation group at 1， 2， and 3 months after treatment was significantly lower than that of the control group （ P ＜0.05）， while the ALB level was significan tly higher （ P ＜0.05）. However， at 6 months after treatment， there was no statistically significant difference in these two indicators between the two groups （ P ＞0.05）. There was no statistically significant difference in eGFR between the two groups at different time points after treatment （ P ＞0.05）. The overall response rates in the observation group at 1 and 2 months after treatment were significantly higher than those in the control group （ P ＜0.05）. There was no statistically significant difference in the overall response rate at the remaining treatment time points and the CR rate at all time points between the two groups （ P ＞0.05）. Patients in the observation group had significantly lower rates of skin abnormalities， elevated blood glucose， and overall adverse reactions compared with the control group （ P ＜0.05）. CONCLUSIONS Compared with MMF combined with glucocorticoids， MMF combined with Budesonide enteric capsules for the treatment of high-risk progressive IgAN patients can reduce proteinuria and improve serum ALB levels more quickly， significantly increase the early overall response rate， and significantly reduce glucocorticoid-related skin adverse reactions， blood glucose elevation， and the overall incidence of adverse reactions， demonstrating a better short-term benefits.

With the understanding of the biological function of BEC， the potential value of DR in disease prognosis and treatment has gradually become a research hotspot. This article systematically reviews the molecular mechanism of DR， its potential as a therapeutic target， and future development directions， as well as novel therapies suggested by targeting these molecular mechanisms， in order to provide a new direction for overcoming current bottlenecks in the treatment of bile duct diseases.

ObjectiveTo investigate the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Baoshan District of Shanghai from 2008 to 2023, and to provide scientific evidence for surveillance and standardized management of HFMD. MethodsCase data for HFMD reported in the China Disease Control and Prevention Information System from 2008 to 2023 were collected. Descriptive epidemiological methods were used to analyze the population characteristics, and the Joinpoint regression models were applied to assess the temporal trends of HFMD in Baoshan District. ResultsA total of 43 853 HFMD cases were reported from 2008 to 2023 in Baoshan District, with a male-to-female ratio of 1.50∶1. The majority of cases were children, among which scattered children and preschool children accounted for 54.67% and 36.58%, respectively, with 88.00% occurring in children under 5 years old. The average annual incidence rate was147.22/100 000 individuals. The pathogen detection rate in 2018 was 58.60% (109/186). Prior to 2020, CoxA16 was the predominant strain, while EV71 was not detected after 2019. ConclusionThe incidence of HFMD in Baoshan District of Shanghai was influenced by multiple factors including the inclusion in the notifiable infectious disease surveillance system, the introduction of EV71 vaccination, and the COVID-19 pandemic timeline. Populations characterized by highly mobility and frequent external contacts were at high risk for HFMD in Baoshan District. The predominant circulating strains had shifted sequentially from EV71 and CoxA16 to CoxA6.
