The thoracolumbar interfascial block with local anesthesia in osteoporotic vertebral compression fractures treated with percutaneous kyphoplasty provides better analgesia compared with local anesthesia alone: A randomized controlled study.

Objective: To evaluate the safety and efficacy of the thoracolumbar interfascial block (TLIPB) in percutaneous kyphoplasty (PKP), and to confirm that the TLIPB further minimizes perioperative pain and residual back pain on the basis of local anesthesia.

Method: From April 2021 to May 2022, 60 patients with osteoporotic vertebral compression fractures were included in this prospective randomized controlled trial. Patients were randomly assigned to a local anesthesia group (A group) or a TLIPB on the basis of local anesthesia group (A + TLIPB group) before PKP.

Midazolam prevents motor neuronal death from oxidative stress attack mediated by JNK-ERK pathway.

Midazolam is a sedative used by patients with mechanical ventilation. However, the potential clinical value is not fully explored. In this report, we made use of a neuroblastoma-spinal cord hybrid motor neuron-like cell line NSC34, and elucidated the potential role of Midazolam on these cells under the insult of oxidative stress.

[Effects of manganismus on proliferation of neural stem cells in mice's hippocampus].

Objective: To explore the effects of manganese poisoning on the proliferation of neural stem cells (NSCs) in mice's hippocampus.

Methods: The mice (weight 8 approximately 10 g) were divided into control group(CG) low-dose group(LDG) middle-dose group(MDG) and high-dose group(HDG)by intraperitoneal injection of 0, 5, 20, 50 mg x kg(-1) x d(-1) of manganese chloride dissolved in physiological saline. The ability of learning and memory was detected by Morris Water Maze, and the proliferation of NSCs in subgranular zone (SGZ) in these mice's hippocampus was also detected by immunohistochemistry.
