This study aimed to observe the mechanism of hydrogen (H) in a lung transplantation model simulated by pulmonary microvascular endothelial cells (PMVECs), which were divided into 5 groups. The blank group was the normal PMVECs. During cold ischemia period, PMVECs in the control, O, or H groups were aerated with no gas, O, or 3% H, and 3% H after transfected with a small interfering RNA targeting Nrf2 in the H+si-Nrf2 group.

This study aimed to investigate the effect of exosomes derived from bone marrow mesenchymal stem cells (BMSCs-EXO) on lung ischemia-reperfusion injury (IRI) in rats and to explore the role of miR-335. The model of rat lung IRI was established by clipping the hilum of left lung for 60 min and opening for 180 min. Forty Sprague-Dawley rats were randomly divided into sham group, IRI group, IRI+PBS group, IRI+EXO group, and IRI+miR-335 inhibitor EXO (IRI+inhibitor-EXO) group (n = 8).

Intervertebral disc degeneration (IVDD) mainly manifests as an imbalance between the synthesis and degradation of cellular and extracellular matrix (ECM) components. The cytokine interleukin (IL)-1β-induced inflammatory response of intervertebral discs causes ECM degradation. The aim of this study was to investigate the effects of a 970-nm diode laser therapy (DLT) on inflammatory cytokine IL-1β and ECM degradation proteinases in nucleus pulposus (NP) tissues in a puncture-induced rabbit IVDD model.

Article Synopsis
  • Intraoperative analgesia is essential for percutaneous transforaminal endoscopic discectomy (PTED), with local anesthesia (LA) typically used, but it often requires additional pain management methods.
  • A new approach called lumbar transforaminal epidural anesthesia (LTEA) was tested, which involves injecting local anesthetics through the intervertebral foramen instead of traditional midline epidural methods, aiming for better pain control and ease of administration.
  • Results indicated that patients receiving LTEA had significantly lower pain scores, higher satisfaction rates with anesthesia, reduced vital signs, and lower total dosages of fentanyl compared to those receiving only LA, suggesting LTEA is a more effective option for pain management during PTED.

Objective: Patients undergoing percutaneous transforaminal endoscopic discectomy (PTED) often complain of unbearable intraoperative pain. This study is to observe clinical effectiveness and safety of intradiscal local anesthetic injection for intraoperative pain relief.

Methods: Total 268 patients who underwent PTED were analyzed.

Postherpetic neuralgia (PHN) is a common complication of herpes zoster. As a kind of continuous acupuncture, indwelling trocar therapy (ITT) involves inserting a trocar into the skin and retaining the soft cannula in the body for 24 h. However, the efficacy and safety of ITT on PHN require further verification.

Background: Neurolytic celiac plexus block (NCPB) is a typical treatment for severe epigastric cancer pain, but the therapeutic effect is often affected by the variation of local anatomical structures induced by the tumor. Greater and lesser splanchnic nerve neurolysis (SNN) had similar effects to the NCPB, and was recently performed with a paravertebral approach under the image guidance, or with the transdiscal approach under the guidance of computed tomography. This study observed the feasibility and safety of SNN via a transdiscal approach under fluoroscopic guidance.

Lung inflation with hydrogen is an effective method to protect donor lungs from lung ischemia-reperfusion injury (IRI). This study aimed to examine the effect of lung inflation with 3% hydrogen during the cold ischemia phase on pyroptosis in lung grafts of rats. Adult male Wistar rats were randomly divided into the sham group, the control group, the oxygen (O) group, and the hydrogen (H) group.

Objectives: Alcohol for intercostal neuralgia may induce severe injection pain. Although nerve block provided partial pain relief, alcohol might be diluted, and the curative effect decreased when the local anesthetic and alcohol were given at the same point. Therefore, we observed the modified method for intercostal neuralgia, a Two-point method, in which the local anesthetic and alcohol were given at different sites.

Background: Lung ischemia-reperfusion injury (LIRI) remains an important factor for the early mortality of lung transplantations. Hydrogen (H2) can attenuate lung injury and improve lung function in animal experiments. In previous studies, pulmonary microvascular endothelial cells (PMVECs) were used to simulate LIRI.

Background: Hydrogen sulfide attenuates lung ischemia-reperfusion injury when inhaled or administered intraperitoneally. This study investigated the effects of lung inflation with HS during the warm ischemia phase on lung grafts from rat donors after cardiac death.

Methods: One hour after cardiac death, donor lungs were inflated in situ for 2 h with either O or HS (O or HS group) during the warm ischemia phase or were deflated as a control procedure (n = 8).

Aims: Lung ischemia-reperfusion injury (IRI) may be attenuated through carbon monoxide (CO)'s anti-inflammatory effect or hydrogen (H2)'s anti-oxidant effect. In this study, the effects of lung inflation with CO, H2, or both during the cold ischemia phase on graft function were observed.

Materials And Methods: Rat donor lungs, inflated with 40% oxygen (control group), 500ppm CO (CO group), 3% H2 (H2 group) or 500ppm CO+3% H2 (COH group), were kept at 4°C for 180min.
