Evaluation of Factors Influencing Postoperative Cognitive Dysfunction in Patients After Cranial Tumor Surgery.

Background: The authors retrospectively analyzed the perioperative data of 81 patients who underwent cranial tumor surgery to explore the factors influencing POCD in patients after the surgery.

Methods: The authors evaluated preoperative cognitive dysfunction using the Mini-Mental State Examination (MMSE) score measured. For patients whose cognitive function was normal, the authors retrieved the MMSE score on the seventh day after surgery and compared it to determine whether the patients had POCD.

MBD1 Contributes to the Genesis of Acute Pain and Neuropathic Pain by Epigenetic Silencing of and Genes in Primary Sensory Neurons.

The transmission of normal sensory and/or acute noxious information requires intact expression of pain-associated genes within the pain pathways of nervous system. Expressional changes of these genes after peripheral nerve injury are also critical for neuropathic pain induction and maintenance. Methyl-CpG-binding domain protein 1 (MBD1), an epigenetic repressor, regulates gene transcriptional activity.

Cuff-leak test combined with interventional bronchoscopy benefits early extubation for patients who received tarp surgery.

Purpose: This study explored the performance characteristics of a cuff-leak test (CLT) combined with interventional fiberoptic bronchoscopy (FBS) for evaluating whether early nasoendotracheal extubation was possible for patients who had received transoral atlantoaxial reduction plate (TARP) internal fixation surgery.

Methods: 318 patients who underwent surgery were retrospectively analyzed (between January 2006 and December 2012). Extubation was performed by conventional approach (CA group, until December 2008) and improved approach (IA group, from January 2009) including CLT and an interventional FBS procedure.

Effect of preemptive local injection of ropivocaine with dexmedetomidine on mirror pain in rats and its mechanism.

Objective: To observe the effect of preemptive local injection of ropivocaine with dexmedetomidine on activation of glial cells and on the mirror pain in rats and its mechanism.

Methods: A total of 48 adult male Sprague-Dawley rats (weighing 180 g-220 g) were included in the study and randomized into 3 groups, Group S, Group R, and Group RD1. A rat model of persistent postoperative pain evoked by skin/muscle incision and retraction was established in the three groups.

Assessment of the relationship between ACE I/D gene polymorphism and renal allograft survival.

Background And Objective: The relationship between the angiotensin-converting enzyme (ACE) insertion/deletion (I/D) gene polymorphism and renal allograft survival after renal transplantation from the published reports are still debatable. This study was performed to evaluate the relationship between the ACE I/D gene polymorphism and renal allograft survival after renal transplantation using meta-analysis.

Method: Eligible studies were identified from PubMed and Cochrane Library on 1 November 2014, and eligible studies were recruited and synthesized using a meta-analysis methodology.

Effect of aquaporin-4 deficiency on intravenous anaesthetic induced hypnotic effects in mice.

The deficiency of aquaporin-4 (AQP4) has been reported to alter release of neurotransmitters in the mouse brain. However, the functional relevance of AQP4 in mediating essential components of the general anaesthetic state is unknown. The aim of the present study was to investigate the role of AQP4 in general anaesthesia in mice lacking AQP4.

[Measurement of the minimum alveolar concentration of sevoflurane during combined anesthesia with sevoflurane, small-dose dexmedetomidine and fentanyl].

Objective: To determine the minimum alveolar concentration (EC(50) and EC(95)) of sevoflurane in body movement response to surgical incision during combined anesthesia with dexmedetomidine, sevoflurane and fentanyl.

Methods: Twenty-six ASA class I or II patients (aged 18-60 years) underwent selective surgery for lumbar disc herniation under general anesthesia with the combination of with dexmedetomidine, sevoflurane and fentanyl. All the patients received infusion with 0.

Case report: intraoperative management of extreme hemodilution in a patient with a severed axillary artery.

We present a case of extreme hemodilution in which appropriately crossmatched blood was not available. A 53-year-old man was admitted to our hospital because of hemorrhagic shock due to multiple stab wounds. His blood type was B, Rh negative, and his intravascular fluid volume was maintained with balanced salt solution and plasma substitutes, i.

[Protective effects of sufentanil pretreatment against acute gastric mucosal lesion in rats and its relationship with acid-sensing ion channels].

Objective: To investigate the effects of sufentanil pretreatment on acute gastric mucosal lesion and its impact on the expression of acid-sensing ion channel 3 (ASIC3) in thoracic dorsal root ganglia (DRG) neurons in rats with water immersion-restraint stress (WIRS).

Methods: Twenty-four Wistar rats were randomly assigned into 3 groups, namely the normal control group (n=6), WIRS group (n=12) and sufentanil pretreatment group (n=6). Gastric mucosal lesion was induced by WIRS, and after 6 h of WIRS, the gastric tissues were excised and observed under microscope, with the ulcer index (UI) calculated.

Changes in erythrocyte membrane ATPases and plasma lipid peroxides in upper abdominal surgery under intravenous procaine-balanced anesthesia.

AIM:To observe the changes in erythrocyte membrane ATPases and plasma lipid peroxides (LPO) patients with in abdominal surgery under intravenous procainebalanced anesthesia.METHODS:By determining the ATPase activities of erythrocyte membrane, effects of upper abdominal surgery under intravenous procaine-balanced anesthesia on the function of erythrocytes were observed in 15 patients undergoing cholecystectomy and gastrectomy (5 males and 10 females, aged 45.9 ± 10.
