PURPOSE: Early mortality in major trauma has decreased, but MODS remains a leading cause of poor outcomes, driven by trauma-induced cytokine storms that exacerbate injuries and organ damage. METHODS: This prospective cohort study included 79 major trauma patients (ISS >15) treated in the National Center for Trauma Medicine, Peking University People's Hospital, from September 1, 2021, to July 31, 2023. Patients (1) with ISS >15 (according to AIS 2015), (2) aged 15-80 years, (3) admitted within 6 h of injury, (4) having no prior treatment before admission, were included. Exclusion criteria were (1) GCS score <9 or AIS score ≥3 for TBI, (2) confirmed infection, infectious disease, or high infection risk, (3) pregnancy, (4) severe primary diseases affecting survival, (5) recent use of immunosuppressive or cytotoxic drugs within the past 6 months, (6) psychiatric patients, (7) participation in other clinical trials within the past 30 days, (8) patients with incomplete data or missing blood samples. Admission serum inflammatory cytokines and pathophysiological data were analyzed to develop machine learning models predicting MODS within 7 days. LR, DR, RF, SVM, NB, and XGBoost were evaluated based on the area under the AUROC. The SHAP method was used to interpret results. RESULTS: This study enrolled 79 patients with major trauma, and the median (Q₁, Q₃) age was 51 (35, 59) years (52 males, 65.8%). The inflammatory cytokine data were collected for all participants. Among these patients, 35 (44.3%) developed MODS, and 44 (55.7%) did not. Additionally, 2 patients (2.5%) from the MODS group succumbed. The logistic regression model showed strong performance in predicting MODS. Ten key cytokines, IL-18, Eotaxin, MCP-4, IP-10, CXCL12, MIP-3α, MCP-1, IL-1RA, Cystatin C, and MRP8/14 were identified as critical to the trauma-induced cytokine storm and MODS development. Early elevation of these cytokines achieved high predictive accuracy, with an AUROC of 0.887 (95% CI 0.813-0.976). CONCLUSION Trauma-induced cytokine storms are strongly associated with MODS. Early identification of inflammatory cytokine changes enables better prediction and timely interventions to improve outcomes.

A 39-year-old male patient was admitted to hospital with abdominal distension, unconsciousness, and anuria. Head computed tomography (CT) showed subarachnoid hemorrhage and diffuse cerebral edema. The high-density area of contrast accumulation region in the high-density CT plaque was 38 HU, and the preliminary diagnosis was SAH, incomplete intestinal obstruction, and sepsis caused by acute cerebrovascular disease. After admission, the patient displayed upturned eyes, limb convulsions, serum procalcitonin level exceeding 100 ng/mL, low blood pressure and septic shock. Imipenem was given for intensive anti-infection therapy. After treatment, procalcitonin levels showed a slow decline, renal function, and intra-abdominal pressure returned to normal, urine volume gradually increased, but platelets still showed a downward trend. Lumbar puncture showed colorless and clear cerebrospinal fluid, and the biochemical and routine results of cerebrospinal fluid were normal. SAH and intracranial infection were excluded, and it was considered that the head CT showed pseudo-subarachnoid hemorrhage. On the 3rd day of admission, laparoscopic exploratory laparotomy+appendectomy+abdominal drainage under general anesthesia were performed. During surgery, purulent gangrene in the appendix was found, with pus adhering to the surface of the intestines and a large amount of pus present in the abdominal cavity. Rhabdomyolysis syndrome developed after surgery. After continuous renal replacement therapy, the indicators gradually returned to normal. The patient was conscious, and the head CT results were normal. The patient was discharged from the hospital on the 19th day after surgery, and no special discomfort and abdominal pain and distension occurred during the 3-month follow-up.

This study reports the diagnosis and treatment of a 26-year-old pregnant woman with severe malnutrition combined with acute pyelonephritis causing sepsis, refractory septic shock and multiple organ failure. A female patient, 26 years old, was admitted to hospital mainly due to "menelipsis for more than 19 weeks, nausea and vomiting for 20 days, fever with fatigue for 3 days". At the end of 19 weeks of intrauterine pregnancy, the patient presented with fever accompanied by urinary tract irritation. Laboratory tests showed elevated inflammatory indicators, and ultrasonography showed bilateral pelvicalyceal dilation. She was diagnosed with acute pyelonephritis, sepsis, acute kidney injury (AKI) and severe malnutrition. After a whole-hospital consultation, the patient was treated with meropenem and vancomycin as antimicrobial therapy, and bilateral nephrostomy drainage was performed simultaneously. After that, the patient suffered a sudden decrease in blood pressure, blood oxygen saturation, and rapid heart rate. Septic shock with multiple organ dysfunction was considered, and she was transferred to intensive care unit (ICU) immediately. After the patient was transferred to ICU, emergency tracheal intubation and ventilator-assisted ventilation were performed. Rapid fluid resuscitation was administered for the patient. While pulse indicator continuous cardiac output (PICCO) monitoring was performed, norepinephrine, terlipressin, and methylene blue were administered to maintain peripheral vascular resistance. Since the patient developed septic cardiomyopathy and cardiogenic shock later, levosimendan and epinephrine were admi-nistered to improve cardiac function. While etiological specimens were delivered, meropenem, teicoplanin and caspofungin were given as initial empiric antimicrobial therapy. Unfortunately, the intrauterine fetal death occurred on the night of admission to ICU. On the 3rd day of ICU admission, a still-born child was delivered vaginally with 1/5 defect of the fetal membrane. On the 6th day of ICU admission, the patient had fever again with elevated inflammatory indicators. After excluding infection in other parts, intrau-terine infection caused by incomplete delivery of fetal membrane was considered. Then emergency uterine curettage was performed and the infection gradually improved. Later the laboratory results showed that the nephrostomy drainage was cultured for Escherichia coli and uterine, cervical and vaginal secretions were cultured for Candida albicans. Due to severe infection and intrauterine incomplete abortion, the patient developed disseminated intravascular coagulation (DIC). Active antimicrobial therapy and blood product supplement were given. However, the patient was critically ill with significant decrease in hemoglobin and platelets combined with multiple organ failure. Thrombotic microangiopathy (TMA) was not excluded yet, so plasma exchange was performed for the patient in order not to delay treatment. The patient underwent bedside continuous renal replacement therapy (CRRT) for AKI. The patient was complicated with acute liver injury, and the liver function gradually returned to normal after liver protection, antimicrobial therapy and other treatments. Due to the application of large doses of vasoactive drugs, the extremities of the patient gradually developed cyanosis and ischemic necrosis. Local dry gangrene of the bilateral toes remained at the time of discharge. In general, the patient suffered from septic shock, cardiogenic shock, combined with DIC and multiple organ dysfunction. After infection source control, antimicrobial therapy, uterine curettage, blood purification treatment, nutritional and metabolic support, the patient was discharged with a better health condition.

Sepsis-related organ dysfunction is associated with increased morbidity and mortality. Previous studies have found that the endothelium plays crucial roles in maintaining the vascular permeability during sepsis, as well as in regulating inflammation and thrombosis. During sepsis, endothelial cells may release cytokines, chemokines, and pro-coagulant factors, as well as express adhesion molecules. In general, endothelial responses during sepsis typically inhibit bacterial transmission and coordinate leukocyte recruitment to promote bacterial clearance. However, excessive or prolonged endothelial activation can lead to impaired microcirculation, tissue hypoperfusion, and organ dysfunction. Given the structural and functional heterogeneity of endothelial cells in different organs, there are potential differences in endothelial responses by organ type, and the risk of organ damage may vary accordingly. This article reviews the endothelial response observed in sepsis and its effects on organ function, summarizes current progress in the development of therapeutic interventions targeting the endothelial response, and discusses future research directions to serve as a reference for researchers in the field.

Fish bile poisoning may damage human liver and kidney, causing degeneration and necrosis. Can also damage brain cells and heart muscle, resulting in nervous system and cardiovascular system lesions. This paper reports a case of a patient who developed multiple organ dysfunction syndrome (MODS) after oral administration of fish bile with Xiexin folk prescription for eye disease. In January 2020, he went to the poisoning and occupational diseases department of the emergency department of Qilu hospital. After receiving hemoperfusion, continuous renal replacement therapy (CRRT) and symptomatic support treatment, the patient was improved and discharged. CRRT combined with HP is one of the rapid and effective methods for the treatment of acute fish bile poisoning.

The 2019 novel coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has occurred in China and around the world. SARS-CoV-2-infected patients with severe pneumonia rapidly develop acute respiratory distress syndrome (ARDS) and die of multiple organ failure. Despite advances in supportive care approaches, ARDS is still associated with high mortality and morbidity. Mesenchymal stem cell (MSC)-based therapy may be an potential alternative strategy for treating ARDS by targeting the various pathophysiological events of ARDS. By releasing a variety of paracrine factors and extracellular vesicles, MSC can exert anti-inflammatory, anti-apoptotic, anti-microbial, and pro-angiogenic effects, promote bacterial and alveolar fluid clearance, disrupt the pulmonary endothelial and epithelial cell damage, eventually avoiding the lung and distal organ injuries to rescue patients with ARDS. An increasing number of experimental animal studies and early clinical studies verify the safety and efficacy of MSC therapy in ARDS. Since low cell engraftment and survival in lung limit MSC therapeutic potentials, several strategies have been developed to enhance their engraftment in the lung and their intrinsic, therapeutic properties. Here, we provide a comprehensive review of the mechanisms and optimization of MSC therapy in ARDS and highlighted the potentials and possible barriers of MSC therapy for COVID-19 patients with ARDS.

Objective To investigate the epidemiological and forensic characteristics of multiple organ dysfunction syndrome （MODS） after severe trauma and explore the reference indexes for determining traumatic MODS. Methods In terms of the number of organs or systems involved in MODS, the number of failures of each organ or system, the first failing organ and the survival time after organ failure, 72 cases of MODS death caused by traffic accidents were retrospectively analyzed. The cases were divided into two groups according to the mean injury severity score （ISS）. The t test was used to analyze the differences in the number of organs or systems involved in MODS in the two groups. Chi-square test was used to analyze the differences in the types of first failing organs and the differences between the two groups in the number of cases of organ or system failure involved in MODS. Wilcoxon signed-rank test was used to analyze the differences between the two groups in survival time of MODS after trauma. Kaplan-Meier survival curve was drawn and Log-Rank test was performed. Results The number of MODS involved organs or systems after trauma in ISS≤35 group was 3-5, and 2-4 in the ISS>35 group （P<0.05）. The cases of MODS organ or system failure after trauma occurred more in brain and lung in the two groups. The first failing organ after trauma was mainly the lung or kidney. The median time of first organ failure after trauma was 2.00 d, the median survival time of MODS after trauma in ISS≤35 group was 6.00 d, and 2.33 d in ISS>35 group （P<0.05）. The survival curve of ISS≤35 group was relatively high and declined gradually, while the survival curve of ISS>35 group was relatively low and the decline was steep （P<0.05）. Conclusion The epidemiological and forensic characteristics of MODS caused by traffic accidents have certain specificity. The ISS and the forensic characteristics of MODS at ISS>35 can be used as reliable reference indexes for evaluation of the causal relationship among trauma, MODS and death.

A 20-month-old male infant with multiorgan dysfunction after Epstein-Barr virus (EBV) infection developed Reye's syndrome. He also suffered from acute liver failure, life-threatening cerebral edema, severe disseminated intravascular coagulation (DIC), and myocardial involvement. EBV infection aggravated the progress of Reye's syndrome, leading to death despite full supportive and symptomatic therapy. This critical case suggested that pediatricians should pay attention to multiorgan involvement of severe EBV infection.

OBJECTIVETo compared the clinical efficacy of laparoscopic repair (LR) versus open repair (OR) for perforated peptic ulcers.

METHODSFrom January 2010 to June 2014, in Shanghai Tongji Hospital, 119 patients who were diagnosed as perforated peptic ulcers and planned to receive operation were prospectively enrolled. Patients were randomly divided into LR (58 patients) and OR(61 patients) group by computer. Intra-operative and postoperative parameters were compared between two groups. This study was registered as a randomized controlled trial by the China Clinical Trials Registry (registration No.ChiCTR-TRC-11001607).

RESULTSThere was no significant difference in baseline data between two groups (all P>0.05). No significant differences of operation time, morbidity of postoperative complication, mortality, reoperation probability, decompression time, fluid diet recovery time and hospitalization cost were found between two groups (all P>0.05). As compared to OR group, LR group required less postoperative fentanyl [(0.74±0.33) mg vs. (1.04±0.39) mg, t=-4.519, P=0.000] and had shorter hospital stay [median 7(5 to 9) days vs. 8(7 to 10) days, U=-2.090, P=0.001]. In LR group, 3 patients(5.2%) had leakage in perforation site after surgery. One case received laparotomy on the second day after surgery for diffuse peritonitis. The other two received conservative treatment (total parenteral nutrition and enteral nutrition). There was no recurrence of perforation in OR group. One patient of each group died of multiple organ dysfunction syndrome (MODS) 22 days after surgery.

CONCLUSIONLR may be preferable for treating perforated peptic ulcers than OR, however preventive measures during LR should be taken to avoid postopertive leak in perforation site.
