Abstract
OBJECTIVE To study the effect of early comprehensive therapy of Traditional Chinese Medicine
(TCM) on motor function of in patients with spinal cord injury. METHODS Fifty-one standard spinal cord injury patients with paraplegia were randomly assigned
to an experimental or control group. The experimental group received TCM comprehensive therapy,
and the control group received modern Western Medicine (WM) treatment for 4 weeks. The motor
score (MS), Barthel Index (BI) and American Spinal Injury Association (ASIA) grading were measured
in both groups before and after treatment. RESULTS After treatment, the MS and BI scores of the TCM comprehensive therapy group improved
significantly (P < 0.01), and there was no significant difference in ASIA grading (P > 0.05). The differences
between the experimental and control groups after treatment were not significant (P > 0.05). CONCLUSION Early TCM comprehensive therapy is an effective method for improving motor function
in patients with spinal cord injury.

A Parallel-Arm Randomized Controlled Trial to Assess the Effects of a Far-Infrared-Emitting Collar on Neck Disorder. MATERIALS 2015; 8:5862-5876. [PMID: 28793539 PMCID: PMC5512659 DOI: 10.3390/ma8095279] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2015] [Revised: 08/08/2015] [Accepted: 08/27/2015] [Indexed: 11/17/2022]
Abstract
The purpose of this study is to assess the beneficial effects of a far-infrared-emitting collar (FIRC) on the management of neck disorders. A neck disorder is generalized as neck muscle pain and its relative mental disorders because the etiologies of the neck's multidimensional syndrome are either muscle impairment or psychiatric distress. This is the first study to determine the efficacy of a FIRC by evaluating objective physical evidence and psychometric self-reports using a parallel-arm randomized sham-controlled and single-blinded design. In this trial, 60 participants with neck disorders were observed at baseline and post-intervention. Compared to the placebo group after a 30-min intervention, the FIRC demonstrated a statistically significant biological effect in elevating skin temperature and promoting blood circulation with p-values 0.003 and 0.020, respectively. In addition, FIRC application significantly reduced neck muscle tension, relieved pain, ameliorated fatigue, improved depression, and decreased anxiety. The FIRC could therefore be a potential treatment for neck disorders.

Exp Ther Med 2015; 9:1631-1638.

Abstract
The host response to spinal cord injury (SCI) can lead to an ischemic environment that can induce cell death. Therapeutic interventions using neurotrophic factors have focused on the prevention of such reactions in order to reduce this cell death. Vascular endothelial growth factor (VEGF) is a potent angiogenic and vascular permeability factor. We hypothesized in this study that batroxobin would exhibit protective effects following SCI by promoting the expression of VEGF to reduce the levels of apoptosis in a rat model of SCI. Ninety adult female Sprague Dawley rats were divided randomly into sham injury (group I), SCI (group II) and batroxobin treatment (group III) groups. The Basso-Bettie-Bresnahan (BBB) scores, number of apoptotic cells and expression of VEGF were assessed at 1, 3, 5, 7, 14 and 28 days post-injury. The BBB scores were significantly improved in group III compared with those in group II between days 5 and 28 post-injury (P<0.05). At each time-point subsequent to the injury, the number of apoptotic cells in group III was reduced compared with that in group II. Compared with group II, treatment with batroxobin significantly increased the expression of VEGF from day 3 until 2 weeks post-SCI (P<0.05), while no significant difference was observed at day 28. These data suggest that batroxobin has multiple beneficial effects on SCI, indicating a potential clinical application.

Abstract
Spinal cord injury is a major cause of disability with devastating neurological outcomes and limited therapeutic opportunities, even though there are thousands of publications on spinal cord injury annually. There are two major types of spinal cord injury, transaction of the spinal cord and spinal cord contusion. Both can theoretically be treated, but there is no well documented treatment in human being. As for spinal cord contusion, we have developed an operation with fabulous result.

Beneficial effects of thymosin β4 on spinal cord injury in the rat. Neuropharmacology 2014; 85:408-16. [PMID: 24937047 DOI: 10.1016/j.neuropharm.2014.06.004] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2014] [Revised: 06/02/2014] [Accepted: 06/05/2014] [Indexed: 12/20/2022]
Abstract
Thymosin β4 (Tβ4) has many physiological functions that are highly relevant to spinal cord injury (SCI), including neuronal survival, anti-inflammation, wound repair promotion, and angiogenesis. The present study investigated the therapeutic value of Tβ4 in SCI, with a focus on its neuroprotective, anti-inflammatory, and vasculoprotective properties. Tβ4 or a saline control was administered by intraperitoneal injection 30 min, 3 days, or 5 days after SCI with mild compression in rat. Locomotor recovery was tested with the Basso-Beattie-Bresnahan scale and a footprint analysis. All behavioral assessments were markedly improved with Tβ4 treatment. Histological examination at 7 days post injury showed that the numbers of surviving neurons and oligodendrocytes were significantly increased in Tβ4-treated animals compared to saline-treated controls. Levels of myelin basic protein, a marker of mature oligodendrocytes, in Tβ4-treated rats were 57.8% greater than those in saline-treated controls. The expression of ED1, a marker of activated microglia/macrophages, was reduced by 36.9% in the Tβ4-treated group compared to that of the saline-treated group. Tβ4 treatment after SCI was also associated with a significant decrease in pro-inflammatory cytokine gene expression and a significant increase in the mRNA levels of IL-10 compared to the control. Moreover, the size of lesion cavity delineated by astrocyte scar in the injured spinal cord was markedly reduced in Tβ4-treated animals compared to saline-treated controls. Given the known safety of Tβ4 in clinical trials and its beneficial effects on SCI recovery, the results of this study suggested that Tβ4 is a good candidate for SCI treatment in humans.

Different TLR4 expression and microglia/macrophage activation induced by hemorrhage in the rat spinal cord after compressive injury. J Neuroinflammation 2013; 10:112.

Abstract
Background Hemorrhage is a direct consequence of traumatic injury to the central nervous system and may cause innate immune reactions including cerebral Toll-like receptor (TLR) 4 upregulation which usually leads to poor outcome in the traumatic brain injury. In spinal cord injury (SCI), however, how hemorrhage induces innate immune reaction in spinal parenchyma remains unknown. The present study aimed to see whether blood component and/or other factor(s) induce TLR4 and microglia/macrophages involved innate immune reactions in the rat spinal cord after traumatic injury. Methods Using the compressive SCI model of the rat, hemorrhage in the spinal cord was identified by hematoxylin-eosin staining. Microglia/macrophage activation, TLR4 expression, and cell apoptosis were investigated by immunohistochemistry. Nuclear factor (NF)-κB p50 level of the two segments of the cord was detected by western blotting assay. With carbon powder injection, blood origination of the hematoma was explored. The blood-spinal cord barrier (BSCB) states of the lesion site and the hematoma were compared with immunohistochemistry and tannic acid-ferric chloride staining. Results Histological observation found blood accumulated in the center of compression lesion site (epicenter) and in the hematoma approximately 1.5 cm away from the epicenter. TLR4 expression, microglia//macrophage activation, and subsequent apoptosis in the area of far-away hematoma were late and weak in comparison to that in epicenter. In addition, TLR4 positive microglia/macrophages appeared to be phagocytotic in the far-away hematoma more obviously than that in the epicenter. Injected carbon powder indicated that accumulated blood of the far-away hematoma originated from the bleeding of the lesion epicenter, and the BSCB around the hematoma was not compromised in the early phase. Accordingly, at 3 days post injury, NF-κB p50 was upregulated based on the similar levels of blood component hemoglobin, and cell apoptosis was obvious in the epicenter but not in the far-away hematoma. Conclusion These data suggest that besides blood component, BSCB compromise and the extent of tissue injury contribute more to TLR4 and microglia/macrophage responses to the spinal cord hemorrhage. Therefore, the innate immune environment is a necessary consideration for the SCI therapy targeting TLR4 and microglia/macrophages.

Abstract
Expansion of the secondary injury following primary spinal cord injury is a major pathological event that increases destruction in the spinal cord, so measures to reduce secondary injury are needed. Our previous study demonstrated that, at the front of the expanding secondary injury in the spinal cord, there is an ischemic area in which many neurons can still be rescued. Therefore, enhancement of blood circulation in the cord may be helpful, and indeed, we found that a traditional Chinese medicine, shu-xue-tong, efficiently reduces the secondary injury. The aim of the present study was to investigate the effect of reducing fibrinogen with Batroxobin, a drug widely used clinically for ischemia, in rats with spinal cord contusion. We found that both 2 and 4 Batroxobin units (BU)/kg efficiently decreased the plasma fibrinogen, and 2 BU/kg significantly increased spinal blood flow, enhanced neuronal survival, mitigated astrocyte and microglia activation, and improved locomotor recovery. However, 4 BU/kg had no effect on the secondary spinal cord injury. These data suggest that Batroxobin has multiple beneficial effects on spinal cord injury, indicating a potential clinical application.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2012; 2012:591298.

Abstract
To determine the role of toll-like receptors (TLRs) myeloid differentiation factor 88 (MyD88) dependent pathway in the spinal cord secondary injury, compression injury was made at T8 segment of the spinal cord in adult male Sprague-Dawley rats. Shown by RT-PCR, TLR4 mRNA in the spinal cord was quickly elevated after compression injury. Intramedullary injection of MyD88 inhibitory peptide (MIP) resulted in significant improvement in locomotor function recovery at various time points after surgery. Meanwhile, injury area, p38 phosphorylation, and proinflammation cytokines in the injured spinal cord were significantly reduced in MIP-treated animals, compared with control peptide (CP) group. These data suggest that TLRs MyD88-dependent pathway may play an important role in the development of secondary spinal cord injury, and inhibition of this pathway at early time after primary injury could effectively protect cells from inflammation and apoptosis and therefore improve the functional recovery.
