摘要信息：Background. Since the 2012 Berlin Definition of the Acute Respiratory Distress Syndrome (ARDS), several developments have supported the need for an expansion of the definition, including the use of high flow nasal oxygen (HFNO), expanding use of pulse oximetry in place of arterial blood gases, use of ultrasound for chest imaging, and the need for applicability in resource-limited settings. Methods. A Consensus Conference of 32 critical care ARDS experts was convened, had six virtual meetings (June 2021-March 2022), and subsequently obtained input from members of several critical care societies. The goal was to develop a definition that would: (1) identify patients with the currently accepted conceptual framework for ARDS; (2) facilitate rapid ARDS diagnosis for clinical care and research; (3) be applicable in resource-limited settings; (4) be useful for testing specific therapies; and (5) be practical for communication to patients and caregivers. Results. The committee made four main recommendations: (1) Include HFNO with a minimum flow rate of  30 liters/min; (2) Use arterial oxygen tension (PaO2)/FiO2  300 mmHg or SpO2/FiO2 < 315 (if SpO2  97%) to identify hypoxemia; (3) Retain bilateral opacities for imaging criteria but add ultrasound as an imaging modality, especially in resource-limited areas; and (4) In resource-limited settings, do not require PEEP, oxygen flow rate, or specific respiratory support devices. Conclusions. We propose a New Global Definition of ARDS that builds on the Berlin Definition. The recommendations also identify areas for future research, including the need for prospective assessments of feasibility, reliability, and prognostic validity of the proposed Global Definition.

摘要信息：Objective:We aimed to evaluate the protective effects of sivelestat sodium on the basis of corticosteroid therapy in patients with moderate-to-severe acute respiratory distress syndrome (ARDS).Methods:We retrospectively investigated 127 patients with confirmed moderate-to-severe ARDS treated in the intensive care unit (ICU) at Dazhou Central Hospital. Patients were divided into the control group (corticosteroids alone) and the combination therapy of steroids and sivelestat sodium (CTSSS) group according to the therapeutic interventions. The primary outcome was in-hospital mortality. And the baseline characteristics and laboratory findings of patients were collected for analysis.Results:The overall mortality rate in 127 patients was 48.8%. There was no statistically significant difference in in-hospital mortality between the CTSSS group and the control group (45.3% vs. 56.1%). In the subgroup of patients aged < 80 years or with an Acute Physiology and Chronic Health Evaluation (APACHE) II score < 30, CTSSS could reduce the risk of mortality (odds ratio [OR] = 0.41, 95% confidence interval [CI], 0.17-0.96, p=0.041; OR = 0.31, 95% CI, 0.13-0.77, p=0.012; respectively). Among patients aged 80 years or older, those with CTSSS exhibited a significantly elevated risk of mortality (OR = 13; 95% CI, 1.20-140.73; p=0.035).Conclusion:Compared with corticosteroids alone, CTSSS could improve oxygenation index, increase lymphocyte count, protect extrapulmonary organs and reduce in-hospital mortality rate in patients with moderate-to-severe ARDS in specific subgroups (age < 80 years or APACHE II score < 30). It might be advisable to avoid CTSSS in moderate-to-severe ARDS patients aged 80 years or older. Prospective studies involving larger sample sizes are needed to verify these findings.

摘要信息：Objective:Sivelestat may reduce postoperative pulmonary injury after total arch replacement (TAR). This study aimed to evaluate whether the preoperative PaO2/FiO2(P/F) ratio affects the efficacy of sivelestat in reducing postoperative pulmonary injury in patients with acute aortic dissection (AAD) who underwent TAR using deep hypothermic circulatory arrest (DHCA). Methods:Data of patients with AAD who underwent TAR using DHCA in a tertiary hospital between February 1, 2022, and December 30, 2022, were retrospectively reviewed. The patients were divided into the sivelestat and control groups. Three subgroup analyses were performed based on the postoperative P/F ratio. The primary clinical outcomes were assessed to determine the efficacy and safety of sivelestat in managing postoperative pulmonary dysfunction in patients undergoing cardiopulmonary bypass. Results:A total of 187 patients were included, with 95 in the sivelestat group and 92 in the control group. No significant differences were found in the clinical variables between the two groups (all P > 0.05), except for some improvements in the inflammatory biomarker levels (including white blood cell count, neutrophil count, and C-reactive protein). Subgroup analysis revealed that sivelestat treatment significantly increased the P/F ratio on the 4th day and 3rd day after TAR in patients with mild lung injury (P = 0.02) and moderate lung injury (P = 0.03), respectively. Additionally, sivelestat reduced the levels of several postoperative inflammatory biomarkers in both subgroups. Conclusions:Among patients with AAD with mild or moderate preoperative lung injury, defined by a low P/F ratio, sivelestat significantly improved the postoperative P/F ratio and attenuated inflammatory responses after TAR. These findings suggest an important avenue for further research.

摘要信息：背景：缺血再灌注损伤（IRI）常导致肾脏损害。虽然中性粒细胞胞外陷阱（NETs）的存在一直被观察到，但它们对IRI的具体影响尚未确定。西维来司他钠是中性粒细胞弹性酶的抑制剂，对NET的形成至关重要，可能为肾脏IRI提供治疗方法，值得进一步研究。 方法：建立小鼠早期肾IRI模型，经损伤标志物和组织学检查证实。免疫荧光和Western blot证实NETs在肾I/R中的作用。通过一套全面的方法进一步评估肾功能和病理，包括周期性酸希夫染色（PAS）和末端脱氧核苷酸转移酶dUTP Nick末端标记（TUNEL）染色，酶联免疫吸附试验（ELISA），实时肾小球滤过率（RT-GFR）监测，聚合酶链反应（PCR），生化分析，以及额外的Western blot和免疫荧光试验。 结果：我们首先量化了肾IRI小鼠的NET表达，并在24小时达到峰值。随后，给予西维来司他钠治疗，导致MPO、CitH3降低，并减轻了肾小管损伤。此外，它还导致血清肌酐、血尿素氮（BUN）、中性粒细胞明胶酶相关脂钙蛋白（NGAL）和肾损伤分子-1 （KIM-1）水平降低。降低肾组织炎症标志物白介素-6 （IL-6）和肿瘤坏死因子-α (TNF-α)的丰度，减轻氧化应激指标丙二醛（MDA）和4羟基烯醛（4HNE）的水平，并伴有肾I/R小鼠肾细胞凋亡减少和GFR升高。 结论：西维来司他钠通过下调中性粒细胞NETs，减少炎症、氧化应激和细胞凋亡，从而改善肾IRI，从而增强肾功能。

摘要信息：Background Recent studies suggest that neutrophil elastase inhibitor (Sivelestat) may improve pulmonary function and reduce mortality in patients with acute respiratory distress syndrome. We examined the association between receipt of sivelestat and improvement in oxygenation among patients with acute respiratory distress syndrome (ARDS) induced by COVID-19. Methods A large multicentre cohort study of patients with ARDS induced by COVID-19 who had been admitted to intensive care units (ICUs). We used propensity score matching to compare the outcomes of patients treated with sivelestat to those who were not. The diferences in continuous outcomes were assessed with the Wilcoxon signed-rank test. Kaplan–Meier method was used to show the 28-day survival curves in the matched cohorts. A log-rank P-test stratifed on the matched pairs was used to test the equality of the estimated survival curves. A Cox proportional hazards model that incorporated a robust sandwich-type variance estimator to account for the matched nature of the data was used to estimate hazard ratios (HR). All statistical analyses were performed with SPSS 26.0 and R 4.2.3. A two-sided p-value of < 0.05 was considered statistically signifcant. Results A total of 387 patients met inclusion criteria, including 259 patients (66.9%) who were treated with sivelestat. In 158 patients matched on the propensity for treatment, receipt of sivelestat was associated with improved oxygenation, decreased Murray lung injury score, increased non-mechanical ventilation time within 28 days, increased alive and ICU-free days within 28 days (HR, 1.85; 95% CI 1.29 to 2.64; log-rank p < 0.001), shortened ICU stay and ultimately improved survival (HR, 2.78; 95% CI 1.32 to 5.88; log-rank p = 0.0074). Conclusions Among patients with ARDS induce by COVID-19, sivelestat administration is associated with improved clinical outcomes.

摘要信息：本研究旨在探讨中性粒细胞胞外陷阱 （NETs） 对肾结石的贡献。方法：来自GSE73680和生物信息学分析的微阵列数据用于鉴定肾结石患者的差异表达基因。通过乙二醇和氯化铵给药建立肾结石大鼠模型。采集血浆检测cf-DNA、DNase I、MPO-DNA、H3Cit、NE，生化分析检测超氧化物歧化酶、丙二醛、肌酐、血尿素氮、钙。免疫荧光染色检测肾组织中 MPO 、 H3Cit 和 NE 。通过 TUNEL 测定评估细胞凋亡。应用 HE 、 过碘酸-Schiff 和 Von Kossa 染色来确定肾脏中的组织学结构、钙沉积和结石形成。给予中性粒细胞弹性蛋白酶抑制剂 Sivelestat （SIVE） 抑制大鼠 NET。结果：在具有 Randall 斑块的肾组织和正常组织中共鉴定出 403 个差异表达基因，其中 270 个上调和 133 个下调基因。对这些失调的基因进行基因本体富集、KEGG 通路和蛋白质-蛋白质相互作用网络分析。此外，在肾结石患者中观察到 NET 标志物增加，包括 cf-DNA 、 DNase I、MPO-DNA 、 H3Cit 和 NE 以及钙沉积物。随后，我们建立了肾结石大鼠模型。我们发现肾结石大鼠 NET 形成显著升高，随着肾结石的发展，肾小管损伤和凋亡细胞增强。引人注目的是，我们发现通过 SIVE 抑制 NETs 可以显着减少钙沉积和凋亡细胞，减轻肾小管损伤，从而改善肾功能。结论：NETs 会促进肾结石的形成，从而加重肾损伤。我们的研究将 NETs 确定为肾结石的潜在诊断和治疗生物标志物。
