Spinal Ninjurin2 contributes to the neuropathic pain via NF-κB-mediated neuroinflammation in the spared sciatic nerve injury rats.

Object: Ninjurin2 (nerve injury induced protein 2, NINJ2) is a molecule which mediates cell-to-cell and cell-to-extracellular matrix interactions in the nervous system. Clinical study shows NINJ2 is associated with the development of postherpetic neuralgia. However, it is lack of direct evidence that NINJ2 participated in neuropathic pain.

The Roles of Chemokine CXCL13 in the Development of Bone Cancer Pain and the Regulation of Morphine Analgesia in Rats.

Chemokines are important regulators of immune, inflammatory, and neuronal responses in peripheral and central pain pathway. The aim of this study was to investigate whether chemokine (C-X-C motif) ligand 13 (CXCL13) and its receptor (C-X-C chemokine receptor type 5, CXCR5) involve in the development of bone cancer pain (BCP) and the regulation of morphine analgesia in rats. The change of pain behaviors in BCP rats were measured by testing paw withdrawal threshold (PWT).

[Effect of age on ED50 of rocuronium for intratracheal intubation in female patients].

Objective: To determine the half-effective dose (IED50) of rocuronium for intratracheal intubation in female patients of different ages by sequential experiments and evaluate the effect of age on IED50 of rocuronium.

Methods: Forty ASA class I-II female patients undergoing elective surgery under general anesthesia were randomly divided (n = 20) into young patient group and elderly patient group. The intratracheal intubation dose was divided into 4 grades by geometric progression, namely 0.
