Hemorrhagic shock (HS) is one of the leading causes of death among young adults worldwide. Multiple organ dysfunction in HS is caused by an imbalance between tissue oxygen supply and demand, which is closely related to the poor prognosis of patient. Mitochondrial dysfunction is one of the key mechanisms contributing to multiple organ dysfunction in HS, while mitochondrial quality control regulates mitochondrial function through a series of processes, including mitochondrial biogenesis, mitochondrial dynamics, mitophagy, mitochondrial-derived vesicles, and mitochondrial protein homeostasis. Modulating mitochondrial quality control can improve organ dysfunction. This review aims to summarize the effects of mitochondrial dysfunction on organ function in HS and discuss the potential mechanisms of mitochondrial quality control, providing insights into the injury mechanisms underlying HS and guiding clinical management.

Multiple sclerosis (MS) is a neuroinflammatory demyelinating disease, mediated by pathogenic T helper 17 (Th17) cells. However, the therapeutic effect is accompanied by the fluctuation of the proportion and function of Th17 cells, which prompted us to find the key regulator of Th17 differentiation in MS. Here, we demonstrated that the triggering receptor expressed on myeloid cells 2 (TREM-2), a modulator of pattern recognition receptors on innate immune cells, was highly expressed on pathogenic CD4-positive T lymphocyte (CD4⁺ T) cells in both patients with MS and experimental autoimmune encephalomyelitis (EAE) mouse models. Conditional knockout of Trem-2 in CD4⁺ T cells significantly alleviated the disease activity and reduced Th17 cell infiltration, activation, differentiation, and inflammatory cytokine production and secretion in EAE mice. Furthermore, with Trem-2 knockout in vivo experiments and in vitro inhibitor assays, the TREM-2/zeta-chain associated protein kinase 70 (ZAP70)/signal transducer and activator of transcription 3 (STAT3) signal axis was essential for Th17 activation and differentiation in EAE progression. In conclusion, TREM-2 is a key regulator of pathogenic Th17 in EAE mice, and this sheds new light on the potential of this therapeutic target for MS.

The World Health Organization (WHO) classification serves as the internationally recognized standard for diagnosing and classifying hematopoietic and lymphoid tissue tumors(WHO-HEAM). Since 2001, it has undergone multiple upgrades and revisions, updating, clarifying, and refining previous tumor diagnostic and classification standards while incorporating numerous new genetic and molecular biological subtypes. In 2022, two classification proposals emerged due to a wealth of clinical and scientific research results: the fifth edition of the WHO hematopoietic and lymphoid tissue classification (WHO-HAEM5), published in Leukemia journal; and the International Consensus Classification (ICC), published in Blood journal. These two schemes differ in their approach to classifying hematopoietic and lymphoid tissue tumors, posing challenges for clinical laboratory diagnosis and treatment.

Hemorrhagic shock, a life-threatening organ hypoperfusion caused by rapid, massive blood loss, is the leading cause of traumatic death in peacetime and wartime. The vascular endothelial glycocalyx (vEG) plays an important role in maintaining microcirculatory homeostasis. Severe ischemia and hypoxia of hemorrhagic shock can damage the vEG, leading to endothelial dysfunction and exacerbated microcirculatory and organ impairments. Therefore, early prevention and treatment of vEG damage in hemorrhagic shock can improve microcirculation dysfunction, which is of paramount importance for therapeutic efficacies and outcomes. There have been many studies on the prevention and treatment of vEG damage in hemorrhagic shock, but none is based on the management of vEG damage. The authors reviewed the progress on the mechanism and preventive and therapeutic strategies of vEG damage caused by hemorrhagic shock, hoping to provide reference for the further research of hemorrhagic shock-induced vEG damage.

OBJECTIVE: To evaluate and summarize the relevant evidence of anticoagulation and bleeding risk management in patients with extracorporeal membrane oxygenation (ECMO), and provide the evidence-based basis for the management of anticoagulation and bleeding during ECMO treatment. METHODS: According to the evidence "6S" pyramid model, all evidence on ECMO anticoagulation management and bleeding risk was searched in relevant databases, organizations and guideline websites at home and abroad. Evidence types included guidelines, expert consensus, systematic evaluation, Meta-analysis and original study. The search time limit was from May 31, 2012 to May 31, 2022. Two researchers with evidence-based research background conducted independent literature quality evaluation of the retrieved evidence, and the evidence that met the quality standards was extracted and summarized based on the opinions of industry experts. RESULTS: A total of 315 articles were retrieved, and 13 articles were included, including 3 guidelines, 6 expert consensus, and 4 Meta-analysis. A total of 27 best evidences were summarized from 7 aspects, including the selection of ECMO anticoagulation, anticoagulation in priming, anticoagulation in operation, anticoagulation monitoring, bleeding and treatment, thrombosis and treatment, and prevention and management of terminal limb ischemia. CONCLUSIONS This study provides evidence-based basis for bleeding prevention and anticoagulant management in ECMO patients. It is recommended to selectively apply the best evidence after evaluating the clinical environmental conditions of medical institutions, so as to improve the prognosis of ECMO patients.
