Ischemic stroke (IS) represents a substantial global health threat, but only a few effective medicines exist to treat IS, with a huge unmet clinical need. Idebenone (IDB), a coenzyme Q10 analogue, has multitarget effects, including enhancing mitochondrial energy metabolism, scavenging free radicals, and anti-inflammation, which is approved in Europe for treating Leber's hereditary optic neuropathy (LHON). However, IDB has poor water solubility and oral bioavailability, resulting in insufficient therapeutic plasma concentrations, even following high-dose oral administration, and limiting its use for brain diseases and acute-phase interventions. To address these challenges, we synthesized and identified novel water-soluble IDB prodrugs and found that compound could adopt intravenous delivery for treating acute IS (AIS) with excellent plasma and brain exposure in normal and IS rats. Besides, significantly alleviated brain infarct and edema and improved motor function and cerebral blood flow in acute and chronic IS rat models. Compound is currently undergoing comprehensive evaluation as a preclinical candidate for anti-AIS.

Antigen-capturing nanomaterials hold great promise for cancer immunotherapy; however, the need for tumor localized administration and limited antigen-binding affinity remains the "Achilles heel" of this strategy. Herein, we present a tumor microenvironment (TME)-activatable nanoplatform, TDR848@FPB, designed for systemic administration and enhanced covalent capture of tumor-associated antigens (TAAs), enabling effective immunotherapy with minimal off-target effects and independent of localized tumor administration. This platform encapsulates a photosensitizer-conjugated, light-activated toll-like receptor (TLR) agonist, which induces immunogenic cell death and triggers a pro-inflammatory TME conducive to antigen capture upon light irradiation.

Hemophilia, an X-linked monogenic disorder, arises from mutations in the or genes, which encode clotting factor VIII (FVIII) or clotting factor IX (FIX), respectively. As a prominent hereditary coagulation disorder, hemophilia is clinically manifested by spontaneous hemorrhagic episodes. Severe cases may progress to complications such as stroke and arthropathy, significantly compromising patients' quality of life.

Purpose: Spinal anesthesia-induced hypotension can cause detrimental effects on both the mother and the fetus, and it remains a significant concern in obstetric anesthesia. The use of vasopressors is considered the most reliable and effective approach. Previous studies have shown that norepinephrine appears to be superior to phenylephrine in maintaining maternal heart rate and cardiac output.

Target-controlled infusion (TCI) systems, originally developed for intravenous drug administration of anesthetic drugs, enable precise drug delivery based on pharmacokinetic-pharmacodynamic (PKPD) models. While widely used in the operating room, their application in the intensive care unit (ICU) remains limited despite the complexity of drug dosing in critically ill patients. This scoping review evaluates existing evidence on the use of TCI systems in ICU settings, focusing on sedation, analgesia, and antibiotic administration.

Purpose: Intrathecal fentanyl improves intraoperative analgesia and reduces hypotension by enhancing subtherapeutic local anesthetic doses during cesarean sections. This study explores whether these advantages are affected by the negative circulatory effects of carbetocin after delivery.
Patients And Methods: This randomized double-blind, non-inferiority trial was conducted at a tertiary hospital in China.
