研究目的:

本研究旨在通过分析脓毒症患者舌下微循环(反映全身微循环状态的无创窗口)与sTM(内皮损伤)、TAT(凝血激活)、PIC(纤溶激活)、tPAIC(纤溶抑制)4项凝血-纤溶标志物的定量关联,明确不同微循环表型对应的核心凝血紊乱因子,并验证“舌下微循环+4项凝血-纤溶标志物”联合模型对患者28天死亡率的预测价值;其原理基于脓毒症“炎症→内皮损伤→凝血-纤溶紊乱→微循环障碍→器官衰竭”的恶性循环,通过将微循环的可视化观察与凝血系统的分子信号结合,破解两者的交互机制,为脓毒症的精准预后分层与干预提供科学依据。  

Objectives of Study:

This study aims to quantitatively analyze the association between sublingual microcirculation (a non-invasive window reflecting systemic microcirculatory status) and four coagulation-fibrinolysis markers, namely soluble thrombomodulin (sTM, indicating endothelial injury), thrombin-antithrombin complex (TAT, indicating coagulation activation), plasmin-α2-antiplasmin complex (PIC, indicating fibrinolysis activation), and tissue plasminogen activator-inhibitor complex (tPAIC, indicating fibrinolysis inhibition) in patients with sepsis. We intend to identify the core coagulation disorder factors corresponding to distinct microcirculatory phenotypes, and validate the predictive value of the combined model integrating "sublingual microcirculation + 4 coagulation-fibrinolysis markers" for 28-day mortality in these patients. The study is grounded in the vicious cycle of sepsis: inflammation → endothelial injury → coagulation-fibrinolysis dysfunction → microcirculatory disturbance → organ failure. By combining visual observation of microcirculation with molecular signals of the coagulation system, we seek to elucidate the interaction mechanism between the two pathways, so as to provide scientific evidence for precise prognostic stratification and targeted intervention of sepsis.

排除标准:

1. 非首次诊断脓毒症且不符合纳入标准第4条的患者; 2. 本次脓毒症为既往脓毒症的复发(定义:与既往脓毒症为同一感染源/病原体,或距既往脓毒症临床治愈时间<3个月)或延续(定义:既往脓毒症未治愈,感染症状、体征或生物标志物持续异常); 3.入院后24小时内死亡或临床预计生存时间 <72小时; 4. 发病至入ICU时间>24h或发病时间无法明确追溯的患者; 5.合并先天性凝血障碍(如血友病)或严重慢性肝功能衰竭(Child-Pugh C级及以上);合并终末期疾病:如晚期恶性肿瘤(预期寿命<6个月)、终末期肾病需长期透析且预期寿命<6个月; 6.合并口腔疾病或条件限制无法进行舌下微循环检测(如严重口腔感染、大量口腔出血、口腔手术后); 7. 妊娠/哺乳期女性; 8. 拒绝或无法签署知情同意。

Exclusion criteria:

1.Patients with non-first diagnosis of sepsis who do not meet the 4th inclusion criterion; 2.The current sepsis episode is a recurrence (defined as being caused by the same infection source/pathogen as the previous sepsis episode, or the time interval from clinical cure of previous sepsis is < 3 months) or persistence (defined as the previous sepsis episode was not cured, with persistent abnormalities in infection-related symptoms, signs or biomarkers) of the previous sepsis episode; 3.Death within 24 hours after admission, or clinically expected survival time < 72 hours; 4.Time interval from sepsis onset to ICU admission > 24 hours, or the onset time cannot be clearly traced; 5.Complicated with congenital coagulation disorders (e.g., hemophilia) or severe chronic liver failure (Child-Pugh grade C or above); complicated with end-stage diseases: e.g., advanced malignant tumor (expected survival time < 6 months), end-stage renal disease requiring long-term dialysis with expected survival time < 6 months; 6.Complicated with oral diseases or limited by conditions that prevent sublingual microcirculation detection (e.g., severe oral infection, massive oral hemorrhage, post-oral surgery); 7.Pregnant or lactating women; 8.Refuse or are unable to sign the informed consent.
