Patients with lower limb paralysis following acute ischemic stroke (AIS) face a significantly elevated risk of deep vein thrombosis (DVT), potentially leading to pulmonary embolism and increased mortality and disability. This review systematically synthesizes the past decade's evidence regarding the epidemiology, pathophysiology, and prevention of DVT in AIS patients with lower limb paralysis. The pathogenesis of DVT in this population is multifactorial, involving venous stasis from immobility, stroke-induced hypercoagulability, endothelial dysfunction, neutrophil extracellular trap-mediated immunothrombosis, and autonomic dysregulation. Effective prevention necessitates individualized risk stratification incorporating clinical assessment, biomarkers, and imaging. Current prophylactic strategies include pharmacological anticoagulation (primarily low-molecular-weight heparin), mechanical interventions (such as intermittent pneumatic compression), and early mobilization and rehabilitation.

## BioRender-Style Schematic Diagram Prompts (Mitochondrial Transfer Mediated EC Transplantation)

### Overall Settings

- Style: Nature sub-journal level, clear lines, bright colors, minimalist elements, highlighting core pathways and cell interactions, no redundant background.
- Layout: Three-column progression (Left: Natural mitochondrial transfer; Middle: Artificial mitochondrial transplantation; Right: PINK1-Parkin mitophagy), columns connected by arrows, with the core conclusion at the top: "Mitochondrial transfer promotes EC transplantation by activating mitophagy, without functional integration."
- Color scheme: MSC (green), EC (blue), mitochondria (red), autophagosome (cyan), signaling molecules (orange), text black (key molecules bolded), uniform scale.

### Left Column: Natural Mitochondrial Transfer (MSC-EC Co-transplantation)

1. Cells and Microenvironment: MSC (hCD90+) and EC (hCD31+) distributed at a 1:3 ratio, background labeled "Ischemic Stress" + red "TNF-α", bottom depicts "Collagen Hydrogel" (grid texture).
2. Transfer Structure: MSC extends 3-4 "Tunneling Nanotubes/TNTs", tubes filled with red mitochondria (arrow pointing to EC), labeled "TNFAIP2 (regulates TNT formation)" "MIRO1 (regulates mitochondrial migration)".
3. Dynamics and Effects: Label "25% of ECs acquire mitochondria within 24h", timeline (0h→7h→14h) labeled "Mitochondria present during 7h angiogenesis, disappear after 14h vascular stabilization, TNF-α can restart transfer"; upper right corner small image compares "No MSC group": EC apoptosis (Annexin-V+), no blood vessels.

### Middle Column: Artificial Mitochondrial Transplantation (No MSC Support)

1. Process and Function: Left side depicts "MSC→Separate Mitochondria→Transplant to EC (mitoAT-EC)", labeled "3:1 donor:recipient ratio"; right side EC labeled with functional indicators: "ATP↑2x" "OCR↑" "H₂O₂-induced apoptosis rate↓50%" "Scratch healing rate↑40%".
2. In Vivo Effects: Mouse hindlimb ischemia model divided into three groups—"No cell group (tissue necrosis)" "Untransplanted EC group (blood flow↓60%)" "mitoAT-EC group (human blood vessels UEA1+, blood flow↑80%)", with simplified version of laser Doppler blood flow diagram.
3. Mitochondrial Characteristics: Label "Depolarization (Ca²⁺ overload)" (JC-10 detection: green↑ red↓), "No mtDNA integration" (sequencing diagram: 7d donor mtDNA undetectable).

### Right Column: Core Molecular Mechanism (Mitophagy)

1. Autophagy Activation: Magnify local mitoAT-EC, red mitochondria wrapped by cyan "Autophagosome LC3B+", labeled "Transplanted mitochondria co-localized with autophagosomes"; pink "PINK1 (accumulates in depolarized mitochondria)" → yellow "Parkin (recruited to mitochondria)".
2. Inhibition Group Comparison: Small icon "shPINK1-M"

Lipid Raft Structure and Function: Precise Characterization Based on Molecular Composition and Multifunctional Regulatory Mechanism Diagram

I. Overall Layout
The diagram is divided into clear upper and lower sections:

Upper part (55%): "Molecular Composition and Structural Characteristics of Lipid Rafts." An "exploded view" is used to analyze a lipid raft microdomain.
Lower part (45%): "Lipid Rafts as Multifunctional Regulatory Platforms." Four parallel functional modules are used to showcase their core functions.

II. Detailed Drawing Steps
Part 1: Molecular Composition and Structural Characteristics of Lipid Rafts (Upper Part of the Diagram)

1. Overall Positioning and Schematic:
At the top center, draw a simplified cell with an oval lipid raft region highlighted on its plasma membrane, labeled "Lipid Raft Microdomain."
Draw an exploded decomposition arrow from the lipid raft, pointing to the enlarged detailed diagram below.
2. Detailed Diagram of Lipid Raft Structure (Core):
Lipid Environment: Draw an oval cross-section of the lipid raft, with a light gray background to represent its special physical phase.
Core Lipid 1: Cholesterol (30-50%):
Draw uniform, dense yellow dots throughout the lipid raft cross-section (color value `#F1C40F`, strictly consistent with the mitochondrial diagram).
Side note: "Cholesterol (30-50%)," with an added explanatory box: "Structural backbone • Rigid sterol ring restricts lipid movement • Forms hydrogen bonds with sphingolipids." A dashed line can be drawn connecting a yellow dot to an adjacent sphingolipid, with the side note "H-bond."
Core Lipid 2: Sphingolipids (40-50%):
Draw red short bars (sphingomyelin SM, `#E74C3C`) and blue short bars with branched sugar chains (glycosphingolipids GSL, such as gangliosides, `#3498DB`), closely interspersed with cholesterol.
Side note: "Sphingolipids (40-50%)," with two sub-points: "Sphingomyelin (SM): Long-chain saturated fatty acids provide tight hydrophobic packing," "Glycosphingolipids (GSL): Exposed sugar chains provide binding sites and spatial stability."
Auxiliary Components: Dotted with a small amount of light green short bars (saturated phospholipids, such as saturated PC, `#27AE60`), side note: "Saturated Phospholipids: Assist in ordered packing."
3. Precise Depiction of Characteristic Proteins:
GPI-anchored Proteins: Draw a spherical protein anchored to the outer leaflet of the membrane via a wavy glycosyl chain (purple). Clearly label "GPI-anchored Protein" and "Interacts with GSLs via sugar chains."
Palmitoylation-modified Proteins: Draw a transmembrane or membrane-associated protein with a palmitic acid chain (orange wavy line) connected to the part extending into the membrane, inserted into the hydrophobic core of the lipid raft. Label "Palmitoylation-modified Protein (e.g., Src kinase)."
Signal Receptors: Draw a typical transmembrane receptor (e.g., growth factor receptor EGFR) with its transmembrane segment located within the lipid raft. Label
