World Journal of Cardiovascular Diseases 2024年第1期14卷 16-26页

Medical history summary: Male, 47 years old, was admitted to the hospital due to “dizziness accompanied by chest tightness and pain for more than 8 days”. One week ago, the patient experienced chest tightness, chest pain accompanied by profuse sweating for 3 hours and underwent emergency percutaneous coronary intervention (PCI) at a local hospital. The procedure revealed left main stem occlusion with subsequent left main stem to left anterior descending artery percutaneous transluminal coronary angioplasty (PTCA). After the procedure, the patient experienced hemodynamic instability, recurrent ventricular fibrillation, and critical condition, thus transferred to our hospital for further treatment. Symptoms and signs: The patient is in a comatose state, unresponsive to stimuli, with bilateral dilated pupils measuring 2.0 mm, exhibiting reduced sensitivity to light reflex, and recurrent fever. Coarse breath sounds can be heard in both lungs, with audible moist rales. Irregular breathing pattern is observed, and heart sounds vary in intensity. No pathological murmurs are auscultated in any valve auscultation area. Diagnostic methods: Coronary angiography results at the local hospital showed complete occlusion of the left main stem, and left main stem to left anterior descending artery percutaneous transluminal coronary angioplasty (PTCA) was performed. However, the distal guidewire did not pass through. After admission, blood tests showed a Troponin T level of 1.44 ng/ml and a Myoglobin level of 312 ng/ml. The platelet count was 1390 × 109/L. Von Willebrand factor (vWF) activity was measured at 201.9%. Bone marrow aspiration biopsy showed active bone marrow proliferation and platelet clustering. The peripheral blood smear also showed platelet clustering. JAK-2 gene testing was positive, confirming the diagnosis of primary thrombocytosis. Treatment methods: The patient is assisted with mechanical ventilation and intra-aortic balloon counterpulsation to improve

Dear Editor,Major depressive disorder(MDD)is one of the most common psychiatric illnesses that significantly increase the risk of suicide.1 Stress-triggered dysfunctions of microglia have been identified as a commonly occurred pathological feature of MDD.1–3 Microglial dysfunction contributes to the pathogenesis of MDD via immunoresponses/neuroinflammation-mediated neural damage and pathological synapse loss-mediated neural circuit disruption.1 Although the involvement of microglia in MDD has been widely investigated,the molecular mechanisms underlying microglial dysfunction remain largely ***,we identified glutaminase 1(Gls1)as one key protein that participates in microglial dysfunction.4–6 Gls1 catalyzes the hydrolysis of glutamine to produce glutamate in the brain.4 Besides its well-known role in excitatory neurotoxicity,we found Gls1 up-regulation in microglia in animal models of Alzheimer’s disease and ischemic stroke.4,7 Gls1 activates microglia to overproduce cytokines and release inflammatory extracellular vesicles,therefore leading to neuroinflammation in animal models of Alzheimer’s disease and ischemic stroke.4–6 More importantly,Gls1 has been found to be up-regulated in the brains of MDD patients,and microglial Gls1 deficiency mitigated LPS-induced depression-like behaviors.8 However,LPS exposure is not an appropriate model to mimic MDD phenotypes,leaving the involvement of Gls1 in MDD an undetermined question.
