Objective To analyze the expression levels of matrix metalloproteinase-10(MMP-10)and Toll-like receptor 2(TLR2)in serum of patients underwent decompression surgery(DC)for severe traumatic brain injury(sTBI),and to explore their relationship with disease outcome.Methods From April 2021 to April 2024,sTBI patients(n=94)who received DC treatment in a single center were collected as the observation group.Another 90 healthy volunteers who underwent physical examinations at our hospital were selected as the control group.Six months after surgery,sTBI patients were assigned into the good group(n=53)and the adverse group(n=41)according to the Glasgow Outcome Scale(GOS).Data was collected from each group and their differences were compared.Enzyme linked immunosorbent assay(ELISA)was used to measure serum levels of MMP-10 and TLR2.Spearman method was used to analyze the correlation between MMP-10,TLR2 levels and disease outcomes.Logistic regression model used to analyze influencing factors of disease outcomes in sTBI patients after DC.The receiver operating characteristic(ROC)curve was applied to evaluate the predictive value of serum MMP-10 and TLR2 levels for disease outcome in sTBI patients after DC.Results Compared with the control group,the expression levels of serum MMP-10 and TLR2 were prominently higher in the observation group(P＜0.05).Compared with the good group,the proportions of sTBI patients with cerebral herniation,multiple brain contusions and lacerations,and serum levels of MMP-10 and TLR2 were significantly higher in the adverse group,while Glasgow Coma Scale(GCS)score was significantly lower(P＜0.05).Serum levels of MMP-10 and TLR2 in sTBI patients were positively correlated with poor prognosis after DC(P＜0.05).Elevated levels of serum MMP-10 and TLR2,and the increased proportions of patients with cerebral herniation and multiple brain contusions were risk factors affecting the disease outcome after DC in sTBI patients,while elevated GCS score was a protective factor(P＜0.05).The area under the curve(AUC)for predicting disease outcome in sTBI patients after DC using serum MMP-10 and TLR2 alone and in combination was 0.839(95％CI:0.749-0.907),0.847(95％CI:0.758-0.913)and 0.925(95％CI:0.852-0.969),respectively.The combined detection was superior to the individual detections(Zcombination-MMP-10=2.199,Zcombination-TLR2=2.377,both P＜0.05).Conclusion The expression levels of serum MMP-10 and TLR2 in sTBI patients are significantly elevated,and both are prominently correlated with disease outcome after DC.

OBJECTIVE: To investigate the efficacy and safety of autologous blood transfusion during weaning from venous-arterial extracorporeal membrane oxygenation (VA-ECMO) under controlled rotational speed. METHODS: A retrospective study was conducted, selecting patients who underwent extracorporeal membrane oxygenation (ECMO) and successfully weaned at the emergency and critical care medicine center of Henan Provincial Third People's Hospital from January 2023 to May 2024. General data including gender, age, body mass index (BMI), European system for cardiac operative risk evaluation (EuroScore), and disease types were collected. Vital signs at weaning [heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and peripheral oxygen saturation], parameters before and after weaning [B-type natriuretic peptide (BNP), hemoglobin (Hb), partial pressure of arterial oxygen (PaO₂), partial pressure of arterial carbon dioxide (PaCO₂), arterial lactate, central venous pressure (CVP), inferior vena cava collapsibility index, left ventricular ejection fraction (LVEF), and right heart load], post-weaning inflammatory markers at 1-day and 3-day [body temperature, white blood cell count (WBC), neutrophil percentage (NEU%), C-reactive protein (CRP), procalcitonin (PCT), interleukin-10 (IL-10)], as well as complications (infection, thrombosis, renal failure, gastrointestinal bleeding) and post-weaning blood return status were recorded. Patients were divided into an observation group (with post-weaning blood return) and a control group (without post-weaning blood return) based on the presence of blood return after weaning. The changes in the aforementioned parameters were compared between the two groups. RESULTS: A total of 62 patients were included, with 31 cases in each group. No statistically significant differences were observed between the two groups in baseline characteristics including gender, age, BMI, and EuroScore. At weaning, the observation group exhibited relatively stable vital signs, with no significant differences in heart rate, SBP, DBP, or peripheral oxygen saturation compared to the control group. After weaning, the observation group showed significantly lower levels of BNP, PaCO₂, arterial lactate, CVP, and right heart load compared to pre-weaning values [BNP (ng/L): 2 325.96±78.51 vs. 4 878.48±185.47, PaCO₂ (mmHg, 1 mmHg≈0.133 kPa): 35.23±3.25 vs. 40.75±4.41, arterial lactate (mmol/L): 2.43±0.61 vs. 6.19±1.31, CVP (cmH₂O, 1 cmH₂O≈0.098 kPa): 8.32±0.97 vs. 15.34±1.74, right heart load: 13.24±0.97 vs. 15.69±1.31, all P < 0.05], while Hb, PaO₂, inferior vena cava collapsibility index, and LVEF were significantly higher than pre-weaning values [Hb (g/L): 104.42±9.78 vs. 96.74±6.39, PaO₂ (mmHg): 94.12±7.78 vs. 75.51±4.39, inferior vena cava collapsibility (%): 28±7 vs. 17±3, LVEF (%): 62.41±6.49 vs. 45.30±4.51, all P < 0.05]. No statistically significant differences were found between the observation group and control group in these parameters. At 3 days post-weaning, the observation group demonstrated significantly lower levels of body temperature, WBC, NEU%, CRP, PCT, and IL-10 compared to 1 day post-weaning [body temperature (centigrade): 36.83±1.15 vs. 37.94±1.41, WBC (×10⁹/L): 7.82±0.96 vs. 14.34±2.15, NEU%: 0.71±0.05 vs. 0.80±0.07; CRP (mg/L): 4.34±0.78 vs. 8.94±1.21, PCT (μg/L): 0.11±0.02 vs. 0.26±0.05, IL-10 (ng/L): 8.93±1.52 vs. 13.51±2.17, all P < 0.05], with no significant differences compared to the control group. No statistically significant differences were observed between the two groups in the incidence of complications including infection, thrombosis, renal failure, and gastrointestinal bleeding. CONCLUSION Autologous blood reinfusion during VA-ECMO weaning under controlled rotational speed is safe and effective, without increasing risks of infection or thrombosis.

Objective:To establish a predictive model for the progression of acute kidney injury (AKI) to stage 3 AKI (renal failure) in the intensive care unit (ICU), so as to assist physicians to make early and timely decisions on whether to intervene in advance.Methods:A retrospective analysis was conducted. Thirty-eight patients with AKI admitted to the intensive care medicine of the Third People's Hospital of Henan Province from January 2018 to May 2023 were enrolled. Patient data including acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) upon admission, serum creatinine (SCr), blood urea nitrogen (BUN), daily urine output during hospitalization, and the timing of continuous renal replacement therapy (CRRT) intervention were recorded. Based on clinically collected pathological data, standardized creatinine value ratio mean polynomial fitting models were established as the first criterion for judging the progression to stage 3 AKI after data cleansing, screening, and normalization. Additionally, standardized creatinine value ratio index fitting models were established as the second criterion for predicting progression to stage 3 AKI.Results:A total of 38 AKI patients were included, including 25 males and 13 females. The average age was (58.45±12.94) years old. The APACHEⅡ score was 24.13±4.17 at admission. The intervention node was (4.42±0.95) days. Using a dual regression model approach, statistical modeling was performed with a relatively small sample size of statistical data samples, yielding a scatter index non-linear regression model for standardized creatinine value ratio data relative to day " n", with y = 1.246?2 x1.164?9 and an R2 of 0.860?1, indicating reasonable statistical fitting. Additionally, a quadratic non-linear regression model was obtained for the mean standardized creatinine value ratio relative to day " n", with y = -0.260?6 x2+3.010?7 x-1.612 and an R2 of 0.998?9, indicating an excellent statistical fit. For example, using a baseline SCr value of 66 μmol/L for a healthy individual, the dual regression model predicted that the patient would progress to stage 3 AKI within 3-5 days. This prediction was consistent when applied to other early intervention renal injury patients. Conclusion:The established model effectively predicts the time interval of the progression of AKI to stage 3 AKI (renal failure), which assist intensive care physicians to intervene AKI as early as possible to prevent disease progression.
