[Minocycline reduces hyperpolarization-activated current in rat substantia gelatinosa neurons].
To investigate the effect of minocycline on hyperpolarization-activated current (Ih) in the substantia gelatinosa (SG) neurons in rat spinal dorsal horn. ⋯ Minocycline suppresses the excitability of SG neurons through inhibiting the amplitude and current density of Ih and thereby contributes to pain modulation.

[Structural changes in the gray matter in patients with trigeminal neuralgia: a voxel-based morphometric study].
To investigate the changes in whole brain gray matter volume in patients with trigeminal neuralgia using voxel-based morphometry (VBM). ⋯ Patients with trigeminal neuralgia had abnormal gray matter volume in some brain regions associated with perception and processing of pain sensation. These changes may provide clues for further exploration of the neuropathogenic basis of trigeminal neuralgia.

[Logistic regression analysis of the risk factors for difficult airway and the cut-off value of height-to-thyromental distance ratio].
To analyze the risk factors for difficult airway in laryngoscopy and mask ventilation. ⋯ Eight airway characteristics were identified to contribute to a difficult airway, including (OR [95%CI]) the height-to-TMD ratio (3.58[1.95-8.46]), modified Mallampati class (3.34 [1.82-7.14]), BMI (3.07 [1.64-6.69]), history of a previous difficult airway (2.79 [1.28-5.25]), a thick neck (2.15 [1.04-4.37]), range of neck movement (1.98 [0.96-3.89]), sternomental and angulus mandibulae distance (1.46 [0.67-3.04]), and inter-incisor distance (1.01 [0.49-2.54]). The optimal cut-off value for the height-to-TMD ratio was 22.8 for predicting a difficult airway.
