Objective. To analyze the correlation between coagulation fibrinolysis function and outcomes during hospitalization in patients with severe traumatic hemorrhagic shock. Methods. A retrospective collection was performed on the clinical data of 106 patients with severe traumatic shock admitted to the hospital between January 2020 and January 2022. According to the injury severity score (ISS), they were divided into the S1 group (ISS <25 points, n = 70) and the S2 group (ISS ≥25 points, n = 36). The prothrombin time (PT), fibrinogen (Fib), thrombin time (TT), and activated partial thromboplastin time (APTT) were detected by the coagulation assay. The aD-dimer (D-D) was detected by an enzyme-linked immunosorbent assay. Antithrombin activity (AT : A) and plasminogen activity (PLG : A) were detected by the chromogenic substrate method. The relationship between coagulation fibrinolysis indexes and injury severity was analyzed by Spearman's correlation analysis. The predictive value of coagulation fibrinolysis indexes for outcomes of patients with severe traumatic hemorrhagic shock was evaluated by receiver operating characteristic (ROC) curves. Results. The levels of PT, APTT, D-D, TT, AT : A and PLG : A in the S2 group were higher than those in S1 group, while the Fib level was lower than that in the S1 group ( P < 0.05 ). A Spearman’s analysis showed that PT, APTT, TT, D-D, AT : A, and PLG : A were positively correlated with injury severity ( P < 0.05 ), while Fib was negatively correlated with it ( P < 0.05 ). Among the 106 patients, there were 89 survived cases and 17 died cases. The levels of PT, APTT, D-D, AT : A and PLG : A in the death group were lower than those in the survival group, while the Fib level was higher than that in the survival group. The results of ROC curve analysis showed that serum PT, APTT, Fib, TT and D-D were of predictive value for outcomes (AUC = 0.713, AUC = 0.683, AUC = 0.712, AUC = 0.761, AUC = 0.730, AUC = 0.765, AUC = 0.673, P < 0.05 ), and cutoff values were 20.29 s, 34.79 s, 3.54 g/L, 20.97 s, 1.42 μg/L, 73.53% and 63.97%, respectively. Conclusion. There is coagulation and fibrinolysis dysfunction in patients with severe traumatic hemorrhagic shock, which is related to injury severity. The coagulation fibrinolysis indexes have a certain predictive value for outcomes of patients.

Sepsis is a dysfunction of various organs caused by a dysfunctional host response induced by infection. In recent years, the mortality rate of sepsis patients, especially the mortality rate of septic shock patients still remains high. Due to the complexity and heterogeneity of sepsis, there is currently a lack of clinical biomarkers that can be widely used for the early assessment of sepsis. In order to find more concise and accurate biomarkers for timely and adequate intervention in sepsis, we explored the value of neutrophil/lymphocyte ratio (NLR) combined with red blood cell distribution width (RDW) in assessing the prognosis of emergency sepsis patients. The results showed that NLR and RDW were closely related to the prognosis of emergency sepsis patients. The combination of the two can evaluate the prognosis of patients with emergency sepsis, which deserves close attention from clinicians.

Purpose. This study aimed to explore the predictive value of the HEART score combined with hypersensitive C-reactive protein (hs-CRP) for 30 d major adverse cardiovascular events (MACEs) in patients with acute chest pain. Methods. 103 patients with acute chest pain admitted to the emergency department of our hospital from May 2020 to May 2022 were selected as the study subjects. The patients’ HEART score and plasma hs-CRP level were recorded. The patients were followed up for 30 d to observe whether MACE occurred. Results. Among 103 patients with acute chest pain, MACE occurred in 8 cases within 30 d of follow-up, and the probability of MACE was 7.76%. There was a statistically significant difference in 30 d MACE risk among patients with different HEART score stratification ( P < 0.05 ). The age, HEART score, and hs-CRP levels of patients in the MACE group were higher than those in the non-MACE group ( P < 0.05 ). The HEART score and the hs-CRP level were independent risk factors for 30 d MACE in patients with acute chest pain ( P < 0.05 ). The AUC of the HEART score combined with hs-CRP in the occurrence of 30 d MACE in patients with acute chest pain was 0.901, which was significantly higher than 0.720 and 0.758 of single detection. Conclusion. The HEART score combined with hs-CRP can better predict the occurrence of 30 d MACE in patients with acute chest pain.
