RESUMO
Objective: Spinal cord injury (SCI) is one of the most devastating central injuries, resulting in serious locomotor deficits. Triad1 is known to play an important role in SCI, but its effects on the inflammatory response and physiological behavior have not been thoroughly studied. This study is aimed at examining the effects of Triad1 on the inflammatory response and neuronal injury in acute SCI in rats. Methods: Twenty-four male Sprague-Dawley (SD) rats were randomly divided into a control group, SCI group, sh-NC group, and Triad1 knockout group (sh-Triad1). The Basso Beattie Bresnahan locomotor rating scale was utilized for the assessment of the motor ability of rats. Hematoxylin and eosin (H&E), Luxol fast blue (LFB), and TUNEL staining were used to assess the pathological injury, demyelination, and neuronal apoptosis, respectively. ELISA was used to detect the levels of IL-1ß, IL-10, and TNF-α, and qRT-PCR was used to examine the expression level of Triad1. Furthermore, the protein levels of Triad1, Bax, Bcl-2, and cleaved caspase-3 were determined using western blotting. Results: The Triad1 expression level was upregulated in damaged spinal cord tissue. Knockdown of Triad1 improved motor function and reduced SCI as well as apoptosis of spinal cord neurons. In addition, the knockdown of Triad1 inhibited the inflammatory response caused by SCI. Conclusion: Knockdown of Triad1 can reduce SCI in rats with acute SCI by inhibiting the inflammatory response and apoptosis.

In the past 10 years, the technology of percutaneous spine endoscopy has been continuously developed. The indications have expanded from simple lumbar disc herniation to various degenerative diseases of the cervical, thoracic, and lumbar spine. Traditional surgery for the treatment of cervical radiculopathy includes anterior cervical decompression surgery, anterior cervical decompression plus fusion surgery, and posterior limited fenestration surgery. This article mainly studies the treatment of cervical spondylosis caused by radiculopathy caused by the nucleus resection of the posterior cervical spine percutaneous spinal endoscopy based on deep learning. In the PPECD group, the height of the intervertebral cavity was measured before the operation and during the final follow-up, and the height change of the intervertebral cavity was evaluated. The relative angle and relative displacement of the sagittal plane of the operation segment in the PPECD group were measured, and the stability was evaluated. Using the cervical spine X-ray Kelvin degeneration evaluation criteria, before and during the final follow-up operation, the degeneration of the adjacent segments of the two groups was evaluated. A retrospective analysis of 26 cases of cervical radiculopathy that met the criteria for diagnosis, inclusion, and exclusion was reviewed. Among them, 11 cases were treated with PPECD surgery; 15 cases were treated with ACDF surgery. According to the evaluation method of Odom, the excellent rate and the good rate of the two groups were compared. According to the location of the lesion, the nerve detection or dull tip device is exposed under the armpit or shoulder of the nerve root, and the protruding nucleus pulposus tissue is explored and removed, and annulus fibrosus is performed as needed. After hemostasis was detected, the surgical instruments were removed and the surgical incision was completely sutured. Before the operation and 3 months after the operation, the final follow-up made no significant difference in the overall average height of the intervertebral cavity (F = 2.586, P > 0.05). The results show that posterior foramen expansion is an effective surgical method for the treatment of cervical spondylotic radiculopathy, but surgical adaptation requires strict management. In order to achieve satisfactory results, appropriate cases must be selected.

BACKGROUND This study aimed to investigate the therapeutic and prognostic effects of percutaneous transforaminal endoscopic decompression (PTED) for degenerative lumbar spinal stenosis (DLSS). MATERIAL AND METHODS One hundred eighty-eight patients with DLSS were randomly divided into the fenestration and the PTED group for decompression treatment. Operative time, incision length, amount of blood loss, length of hospitalization, and rates of complications in the 2 groups were compared. All patients underwent computed tomography (CT) scanning and magnetic resonance imaging (MRI) on the first postoperative day. All patients were assessed preoperatively and the treatment effects at 3, 6, and 12 months postoperatively were evaluated using visual analog scale (VAS), Japanese Orthopedic Association Score (JOA) and Oswestry Disability Index (ODI). The modified MacNab criteria were used to assess patient satisfaction 1 year after surgery at the last follow-up. RESULTS Patients who underwent PTED had shorter incisions, less blood loss, and shorter hospital stays than those in the fenestration group, but operative times and complication rates were similar in the 2 groups. Moreover, CT scanning and MRI revealed similar treatment effects in the 2 groups. Compared with preoperative status, improvements in VAS, ODI, and JOA scores occurred at different times after surgery in the 2 groups. In particular, all 3 scores in the PTED group were higher than those in the fenestration group at 3 and 6 months postoperatively. There were no significant differences in MacNab scores between the 2 groups. CONCLUSIONS PTED is safer and more effective than traditional fenestration for management of DLSS.

The healing of burn wounds has been widely characterized to be highly intricate, involving processes such as neo-vascularization, granulation, re-epithelialization, inflammation and wound contraction. Various therapies are available for the management of burn wounds; however, a truly effective therapeutic strategy has yet to be identified due to safety issues. The aim of the present study was to assess and confirm the burn wound healing properties of the compounds asiaticoside (AE) and madecassoside (MA), which are found in the herb Centella asiatica. The cytotoxic nature of the AE and MA were inspected and were confirmed to be non-toxic up to 500 ppm. The compounds AE and MA increased monocyte chemoattractant protein-1 production, but caused no significant effect on vascular endothelial growth factor production. In addition, an in vivo animal burn model was employed to represent the features of burn wound healing. Hence, the present results warrant the further investigation of C. asiatica extracts for use in burn healing.
