Mechanical Allodynia Induced by Nucleoside Reverse Transcriptase Inhibitor Is Suppressed by p55TNFSR Mediated by Herpes Simplex Virus Vector Through the SDF1 alpha/CXCR4 System in Rats.
In the human immunodeficiency virus (HIV)-associated sensory neuropathy, neuropathic pain associated with the use of nucleoside reverse transcriptase inhibitors (NRTIs) in patients with HIV/acquired immunodeficiency syndrome is clinically common. While evidence demonstrates that neuropathic pain is influenced by neuroinflammatory events that include the proinflammatory molecules, tumor necrosis factor-α (TNF-α), stromal cell-derived factor 1-α (SDF1-α), and C-X-C chemokine receptor type 4 (CXCR4), the detailed mechanisms by which NRTIs contribute to the development of neuropathic pain are not known. In this study, we investigated the role of these proinflammatory molecules in the dorsal root ganglion (DRG) and the spinal dorsal horn in NRTIs-mediated neuropathic pain state. ⋯ Our studies demonstrate that TNF-α through the SDF1/CXCR4 system is involved in the NRTIs-related neuropathic pain state and that blocking the signaling of these proinflammatory molecules is able to reduce NRTIs-related neuropathic pain. These results provide a novel mechanism-based approach (gene therapy) to treating HIV-associated neuropathic pain.

Randomized Controlled Trial
Infusion of 7.2% NaCl/6% Hydroxyethyl Starch 200/0.5 in On-Pump Coronary Artery Bypass Surgery Patients: A Randomized, Single-Blind Pilot Study.
NaCl 7.2%/6% hydroxyethyl starch (HES) 200/0.5 (HSH) has shown its beneficial effects in cardiac surgery and immunomodulatory values in experiment and human studies. However, there is concern regarding detrimental renal effects of chloride and HES in the intensive care setting. ⋯ NaCl 7.2%/6% hydroxyethyl starch 200/0.5 does not lead to the increase in AKI incidence when used for the volume therapy in on-pump coronary artery bypass surgery patients. NaCl 7.2%/6% hydroxyethyl starch 200/0.5 usage enhanced neither tubular injury nor alteration of glomerular filtration. In addition, HSH can reduce the level of the inflammatory mediators after surgery.

Epidural stimulation (ES) of the lumbosacral spinal cord has been used to facilitate standing and voluntary movement after clinically motor-complete spinal-cord injury. It seems of importance to examine how the epidurally evoked potentials are modulated in the spinal circuitry and projected to various motor pools. We hypothesized that chronically implanted electrode arrays over the lumbosacral spinal cord can be used to assess functionally spinal circuitry linked to specific motor pools. ⋯ Epidural electrical stimulation of rostral and caudal areas of lumbar spinal cord resulted in a selective topographical recruitment of proximal and distal leg muscles, as revealed by both magnitude and thresholds of the evoked potentials. ES activated both afferent and efferent pathways. The components of neural pathways that can mediate motor-evoked potentials were highly dependent on the stimulation parameters and sensory conditions, suggesting a weight-bearing-induced reorganization of the spinal circuitries.
