Knowledge mapping and emerging trends in cognitive impairment associated with chronic pain: A 2000-2024 bibliometric study.

Chronic pain is commonly recognized as a distressing symptom or a standalone disease, with over half of those affected experiencing cognitive impairment, which significantly impacts their quality of life. Despite a recent surge in literature on cognitive impairment associated with chronic pain, a comprehensive bibliometric analysis in this field has yet to be conducted. In this study, we performed a bibliometric analysis on this topic.

STING Driving Synaptic Phagocytosis of Hippocampal Microglia/Macrophages Contributes to Cognitive Impairment in Sepsis-Associated Encephalopathy in Mice.

Background: Sepsis-associated encephalopathy (SAE) is a serious neurologic complication in septic patients with poor prognoses. There is increasing evidence that stimulator of interferon genes (STING) plays a crucial role in neuroinflammation and cognitive impairment. However, whether sepsis associated with STING changes contributes to cognitive impairment is unknown.

The 90% effective concentration of alfentanil combined with 0.075% ropivacaine for epidural labor analgesia: a single-center, prospective, double-blind sequential allocation biased-coin design.

Purpose: More literature studies have reported that alfentanil is safe and effective for labor analgesia. However, there is no unified consensus on the optimal dosage of alfentanil used for epidural analgesia. This study explored the concentration at 90% of minimum effective concentration (EC90) of alfentanil combined with 0.

A role of GABA receptor α1 subunit in the hippocampus for rapid-acting antidepressant-like effects of ketamine.

Ketamine can produce rapid-acting antidepressant effects in treatment-resistant patients with depression. Although alterations in glutamatergic and GABAergic neurotransmission in the brain play a role in depression, the precise molecular mechanisms in these neurotransmission underlying ketamine's antidepressant actions remain largely unknown. Mice exposed to FSS (forced swimming stress) showed depression-like behavior and decreased levels of GABA (γ-aminobutyric acid), but not glutamate, in the hippocampus.

Perioperative intravenous S(+)-ketamine for acute postoperative pain in adults: study protocol for a multicentre, randomised, open-label, positive-controlled, pragmatic clinical trial (SAFE-SK-A trial).

Introduction: Postoperative pain remains incompletely controlled for decades. Recently, multimodal analgesia is emerging as a potential approach in the management of postoperative pain. Therein, S(+)-ketamine is appealing as an adjuvant drug in multimodal analgesia due to its unique pharmacological advantages.

[Effect of transcutaneous electrical acupoint stimulation on catheter related bladder discomfort after ureteroscopic lithotripsy].

Objective: To verify the efficacy of transcutaneous electrical acupoint stimulation (TEAS) on catheter related bladder discomfort after ureteroscopic lithotripsy.

Methods: Sixty male patients with selective ureteroscopic lithotripsy under general anesthesia were randomly divided into a TEAS group (30 cases, one case dropped off) and a sham TEAS group (30 cases, 2 cases dropped off). Before anesthesia induction, the patients in the TEAS group were treated with TEAS at Guanyuan (CV 4), Zhongji (CV 3), Zusanli (ST 36) and Sanyinjiao (SP 6) for 30 min, with disperse-dense wave, frequency of 2 Hz/ 15 Hz and current intensity of 6 to 10 mA.

Penehyclidine hydrochloride attenuates the cerebral injury in a rat model of cardiopulmonary bypass.

This study investigated the effect of penehyclidine hydrochloride (PHC) on regulatory mediators during the neuroinflammatory response and cerebral cell apoptosis following cardiopulmonary bypass (CPB). Forty-eight rats were randomly divided among 4 groups as follows: sham-operation, vehicle, low-dose PHC (0.6 mg·(kg body mass)(-1)), and high-dose PHC (2.

Penehyclidine hydrochloride preserves the intestinal barrier function in patients undergoing cardiopulmonary bypass.

Objective: The study objective was to investigate the protective effect of penehyclidine hydrochloride on intestinal barrier function integrity and its therapeutic potential on endotoxemia and systemic inflammatory response in patients undergoing cardiopulmonary bypass.

Methods: Forty patients undergoing cardiac valve replacement with cardiopulmonary bypass were enrolled in the study. All patients were randomly divided into the penehyclidine hydrochloride or control group (20 patients in each group).

Probiotics can alleviate cardiopulmonary bypass-induced intestinal mucosa damage in rats.

Background: Cardiopulmonary bypass (CPB) is commonly applied to support circulation during heart surgery but frequently causes adverse effects.

Aims: The purpose of this study was to examine the potential of probiotics to improve small intestinal mucosa barrier function after CPB.

Methods: Twenty-four adult male SD rats were randomly divided into sham-operated (S), CPB-operated (CPB), and probiotic-fed (Y) groups.

Effects of penehyclidine hydrochloride on rat intestinal barrier function during cardiopulmonary bypass.

Aim: To test the ability of penehyclidine hydrochloride (PHC) to attenuate intestinal injury in a rat cardiopulmonary bypass (CPB) model.

Methods: Male Sprague-Dawley rats were randomly divided into six groups (eight each): sham-operated control; sham-operated low-dose PHC control (0.6 mg/kg); sham-operated high-dose PHC control (2.
