VX-765 Alleviates Circadian Rhythm Disorder in a Rodent Model of Traumatic Brain Injury Plus Hemorrhagic Shock and Resuscitation.

Severe traumatic brain injury (TBI) can result in persistent complications, including circadian rhythm disorder, that substantially affect not only the injured people, but also the mood and social interactions with the family and the community. Pyroptosis in GFAP-positive astrocytes plays a vital role in inflammatory changes post-TBI. We determined whether VX-765, a low molecular weight caspase-1 inhibitor, has potential therapeutic value against astrocytic inflammation and pyroptosis in a rodent model of TBI plus hemorrhagic shock and resuscitation (HSR).

CORM-3 alleviates the intestinal injury in a rodent model of hemorrhage shock and resuscitation: roles of GFAP-positive glia.

Hemorrhagic shock and resuscitation (HSR) can induce severe intestinal damages, thereby leading to sepsis and long-term complications including dysbacteriosis and pulmonary injury. The NOD-like receptor protein 3 (NLRP3) inflammasome facilitates inflammation-associated cell recruitment in the gastrointestinal tract, and participates in many inflammatory bowel diseases. Previous studies have shown that exogenous carbon monoxide (CO) exerts neuroprotective effects against pyroptosis after HSR.

Assessment of nucleus accumbens impairment in a rat model of postoperative cognitive dysfunction using diffusion tensor imaging.

Background: Postoperative cognitive dysfunction (POCD) often occurs in elderly patients, causing depression and other symptoms. Nucleus accumbens (NAc) is involved in depression. We investigate the diffusion tensor imaging (DTI) parameters of NAc in a POCD model of depression.

Abdominal surgery plus sevoflurane exposure induces abnormal emotional changes and cognitive dysfunction in aged rats.

Background: Cognitive impairment, which includes perioperative psychological distress and cognitive dysfunction, can be determined by preoperative and post-operative neuropsychological tests. Several mechanisms have been proposed regarding the two-way communication between the immune system and the brain after surgery. We aimed to understand the mechanisms underlying perioperative neurocognitive disorders (PND) in elderly rats using an experimental abdominal surgery model.

Esketamine alleviates postoperative cognitive decline via stimulator of interferon genes/ TANK-binding kinase 1 signaling pathway in aged rats.

Background: Postoperative cognitive decline (POCD) is a common complication after surgery and anesthesia among the elderly. Yet the potential mechanism of POCD remains ambiguous, with limited therapeutic measures currently available. Ketamine has been reported to attenuate POCD after cardiac surgery.
