Abstract
Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide, and destruction of the cerebrovascular system is a major factor in the cascade of secondary injuries caused by TBI. Laser speckle imaging (LSCI)has high sensitivity in detecting cerebral blood flow. LSCI can visually show that transcranial focused ultrasound stimulation (tFUS) treatment stimulates angiogenesis and increases blood flow. To study the effect of tFUS on promoting angiogenesis in Controlled Cortical impact (CCI) model. tFUS was administered daily for 10 min and for 14 consecutive days after TBI. Cerebral blood flow was measured by LSCI at 1, 3, 7 and 14 days after trauma. Functional outcomes were assessed using LSCI and neurological severity score (NSS). After the last test, Nissl staining and vascular endothelial growth factor (VEGF) were used to assess neuropathology. TBI can cause the destruction of cerebrovascular system. Blood flow was significantly increased in TBI treated with tFUS. LSCI, behavioral and histological findings suggest that tFUS treatment can promote angiogenesis after TBI.

Abstract
The damage caused by contusive traumatic brain injuries (TBIs) is thought to involve breakdown in neuronal communication through focal and diffuse axonal injury along with alterations to the neuronal chemical environment, which adversely affects neuronal networks beyond the injury epicenter(s). In the present study, functional connectivity along with brain tissue microstructure coupled with T2 relaxometry were assessed in two experimental TBI models in rat, controlled cortical impact (CCI) and lateral fluid percussive injury (LFPI). Rats were scanned on an 11.1 Tesla scanner on days 2 and 30 following either CCI or LFPI. Naive controls were scanned once and used as a baseline comparison for both TBI groups. Scanning included functional magnetic resonance imaging (fMRI), diffusion weighted images (DWI), and multi-echo T2 images. fMRI scans were analyzed for functional connectivity across laterally and medially located region of interests (ROIs) across the cortical mantle, hippocampus, and dorsal striatum. DWI scans were processed to generate maps of fractional anisotropy, mean, axial, and radial diffusivities (FA, MD, AD, RD). The analyses focused on cortical and white matter (WM) regions at or near the TBI epicenter. Our results indicate that rats exposed to CCI and LFPI had significantly increased contralateral intra-cortical connectivity at 2 days post-injury. This was observed across similar areas of the cortex in both groups. The increased contralateral connectivity was still observed by day 30 in CCI, but not LFPI rats. Although both CCI and LFPI had changes in WM and cortical FA and diffusivities, WM changes were most predominant in CCI and cortical changes in LFPI. Our results provide support for the use of multimodal MR imaging for different types of contusive and skull-penetrating injury.

Abstract
Transport of interstitial fluid and solutes plays a critical role in clearing metabolic waste from the brain. Transcranial application of focused ultrasound (FUS) has been shown to promote localized cerebrospinal fluid solute uptake into the brain parenchyma; however, its effects on the transport and clearance of interstitial solutes remain unknown. We demonstrate that pulsed application of low-intensity FUS to the rat brain enhances the transport of intracortically injected fluorescent tracers (ovalbumin and high molecular-weight dextran), yielding greater parenchymal tracer volume distribution compared to the unsonicated control group (ovalbumin by 40.1% and dextran by 34.6%). Furthermore, FUS promoted the drainage of injected interstitial ovalbumin to both superficial and deep cervical lymph nodes (cLNs) ipsilateral to sonication, with 78.3% higher drainage observed in the superficial cLNs compared to the non-sonicated hemisphere. The application of FUS increased the level of solute transport visible from the dorsal brain surface, with ~ 43% greater area and ~ 19% higher fluorescence intensity than the unsonicated group, especially in the pial surface ipsilateral to sonication. The sonication did not elicit tissue-level neuronal excitation, measured by an electroencephalogram, nor did it alter the molecular weight of the tracers. These findings suggest that nonthermal transcranial FUS can enhance advective transport of interstitial solutes and their subsequent removal in a completely non-invasive fashion, offering its potential non-pharmacological utility in facilitating clearance of waste from the brain.

Abstract
Here, we treated moderately traumatic brain injury (TBI) rats with different modalities, including transplantation with mesenchymal stem cells (MSCs), treatment with low-intensity transcranial ultrasound stimulation (LITUS), and a combination of the two. After the TBI rat model was established, MSCs (in situ injection within 24 h after injury), LITUS (continuous uninterrupted treatment for 28 days) or combined MSCs + LITUS were administered, and mNSS score, performance of behavior and multiple protein levels were compared between groups by behavioral observation, neurological function assessment and pathological analysis. Nestin, neuron-specific enolase (NSE), growth-associated protein 43 (GAP-43) and postsynaptic density protein (PSD-95) were significantly increased and glial fibrillary acidic protein (GFAP) was significantly decreased in the hippocampus of rats in the combination treatment group; brain-derived neurotrophic factor (BDNF), tumor necrosis factor-α (TNF-α) and aquaporin-4 (AQP-4) were significantly decreased in the injured peripheral cortex. The result of mNSS scores was: TBI group > LITUS group > MSCs group > MSCs+LITUS group > sham group. The alternate correct rate of Y-maze was: sham group > MSCs+LITUS group > MSCs group > LITUS group > TBI group. This data compares the efficacy of MSCs, LITUS, and combination therapy on the level expression of stem cell differentiation related proteins, synaptic plasticity-related proteins, neurotrophic factors, inflammatory factors, and edema-related proteins after TBI by quantitative pathological examination. For a complete description, interpretation, and discussion of the data refer to the article in press [1].

Study of the mechanism by which MSCs combined with LITUS treatment improve cognitive dysfunction caused by traumatic brain injury. Neurosci Lett 2022; 787:136825. [PMID: 35933061 DOI: 10.1016/j.neulet.2022.136825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 07/28/2022] [Accepted: 07/31/2022] [Indexed: 11/26/2022]
Abstract
Traumatic brain injury (TBI) substantially affects the quality of life of patients, and an effective therapy is unavailable. Previous studies have shown that mesenchymal stem cells (MSCs) and low-intensity transcranial ultrasound (LITUS) are effective treatments for neurological damage, inflammation, edema and cognitive impairment caused by TBI. However, it is unclear whether the combination of the two treatments exerts an additive effect. In this study, a rat TBI model was established using the controlled cortical impact (CCI) method. Neurological function was assessed by determining the rat modified neurological score (mNSS), and cognitive function was assessed using the Y-maze. Pathological changes in the injured tissue were observed using hematoxylin-eosin (HE) staining and immunohistochemistry (IHC), and western blot was performed to detect the expression levels of Nestin, neuron-specific enolase (NSE), glial fibrillary acidic protein (GFAP), growth-associated protein-43 (GAP-43), postsynaptic density protein (PSD-95), brain-derived neurotrophic factor (BDNF), tumor necrosis factor-α (TNF-α), and aquaporin-4 (AQP-4). Real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was performed to detect the expression levels of GAP-43, PSD-95, BDNF, TNF-α, and AQP-4 mRNA to investigate whether MSCs combined with LITUS exert an additive therapeutic effect of alleviating the cognitive dysfunction caused by TBI and the possible mechanisms involved. Rats exhibited cognitive dysfunction 28 days after TBI, and MSCs combined with LITUS treatment ameliorated the cognitive deficits caused by TBI via increasing Nestin, NSE, GAP-43, PSD-95, and BDNF expression and attenuating the inflammatory response and edema caused by TBI via reducing TNF-α and AQP-4 expression. According to these results, MSCs combined with LITUS is more effective than MSCs alone for the treatment of TBI, and the mechanism may be the promotion of neuronal proliferation and differentiation, and the attenuation of the inflammatory response and edema, which ameliorates the spatial learning memory impairment caused by TBI. MSCs combined with LITUS treatment represents a new approach for the clinical treatment of patients with TBI.
