Ultrasonic visualization technique for anatomical and functional analyses of the sciatic nerve in rats.

Background And Objective: Ultrasound has been widely used in the diagnosis and minimally invasive treatment of peripheral nerve diseases in the clinic, but there is still a lack of feasibility analysis in rodent models of neurological disease. The purpose of this study was to investigate the changes in the cross-sectional area of the sciatic nerve of different genders and body weights and to explore the effectiveness and reliability of an ultrasound-guided block around the sciatic nerve in living rats.

Methods: Using ultrasound imaging anatomy of the sciatic nerve of rats, the cross-sectional area of the sciatic nerve in rats of different genders from 6 to 10 weeks old was calculated, and then analyzed its correlation with body weight.

Mdivi-1 improves postoperative neurocognitive disorders in aged rats undergoing splenectomy by inhibiting dynamin-related protein-1.

Background: The regulatory role of mitochondria in the inflammatory response of the nervous system postoperatively remains unclear. This study explored the relationship between mitochondria and postoperative neurocognitive dysfunction (PNCD) by regulating mitochondrial function in aged rats undergoing splenectomy.

Methods: A total of 120 aged rats were randomly divided into five groups (n=24) as follows: Control group (not subjected to any form of treatment), Sham group (subjected only to sham-splenectomized operation after anesthesia), Splenectomy group (only underwent splenectomy after anesthesia), Synonyms Mitochondrial division inhibitor 1 (Mdivi-1) group [treated with Mdivi-1, a dynamin-relatedprotein 1 (Drp1) inhibitor], and Dimethyl Sulfoxide (DMSO) group (treated with DMSO, a solvent).

Emergency tracheal intubation peri-operative risk factors and prognostic impact after esophagectomy.

Background: Emergent endotracheal intubation (ETI) is a serious complication after Oesophagectomy. It is still unclear that perioperative risk factors and prognosis of these patients with ETI.

Methods: Between January 2015 and December 2018, 21 patients who received ETI after esophagectomy were enrolled (ETI group) at the department of thoracic surgery, Fujian Union hospital, China.

Emergency tracheal intubation during off-hours is not associated with increased mortality in hospitalized patients: a retrospective cohort study.

Background: The prognosis of hospitalized patients after emergent endotracheal intubation (ETI) remains poor. Our aim was to evaluate the 30-d hospitalization mortality of subjects undergoing ETI during daytime or off-hours and to analyze the possible risk factors affecting mortality.

Methods: A single-center retrospective study was performed at a university teaching facility from January 2015 to December 2018.

Comparison of the short-term efficacy of sequential treatment with intravesical single-port laparoscopic partial cystectomy with bladder preservation or open partial cystectomy in combination with cisplatin plus gemcitabine chemotherapy.

This study aimed to assess the short-term efficacy of sequential therapy for T2/T3a bladder cancer with intravesical single-port laparoscopic partial cystectomy or open partial cystectomy combined with cisplatin plus gemcitabine (GC) chemotherapy in a prospective randomized controlled study. Thirty patients with bladder cancer who underwent open partial cystectomy (group A) or single-port laparoscopic partial cystectomy (group B) and received standard GC chemotherapy were analyzed. Perioperative functional indicators and tumor recurrence during a 1-year postoperative follow-up were compared between the two groups.

Comparative outcomes of peripheral nerve blocks versus general anesthesia for hip fractures in geriatric Chinese patients.

Background: Geriatric patients undergoing hemiarthroplasty for hip fractures have unacceptably high rates of postoperative complications and mortality. Whether anesthesia type can affect the outcomes has still been inconclusive.

Objectives: We compared general anesthesia (GA) and peripheral nerve blocks (PNBs) on postoperative complications and mortality in elderly patients with femoral neck fractures (FNF) undergoing hemiarthroplasty.

Peripheral nerve blocks versus general anesthesia for total knee replacement in elderly patients on the postoperative quality of recovery.

Background: Both peripheral nerve blocks with sedation or general anesthesia can be used for total knee replacement surgery.

Objectives: We compared these anesthetic techniques on the postoperative quality of recovery early in elderly patients.

Materials And Methods: In our study, 213 patients who were ≥65 years old and undergoing total knee replacement were randomized to peripheral nerve blocks (PNBs) - lumbar plexus and sciatic - with propofol sedation, or general anesthesia with combined propofol and remifentanil.

[Anesthetic management of elderly patients during percutaneous endoscopic gastrostomy].

Objective: To evaluate anesthetic techniques for elderly patients during percutaneous endoscopic gastrostomy (PEG).

Methods: Clinical data about 5 cases aged 80 years or more undergoing PEG from June 2012 to May 2013 in Chinese People's Liberation Army General Hospital were retrospectively analyzed and literature review.

Results: Analgesia/minimal sedation combined with local anesthesia (LA including throat spray and operative site infiltrated ) is employed in the one of patients with Tracheoesophageal Fistula (TEF), for the remaining patients, analgesia/deep sedation and LA combination were used, during induction, temporary respiratory depression, blood pressure and heart rate decreased occurred respectively in the different patient, assisted ventilation and ephedrine IV was effective, the anesthesia strategy was to maintain a desired sedation with propofol or etomidate intravenously in small increments or by adjusted infusion , and to keep SpO2 at 95% or more with a supplemental oxygen through face mask under spontaneous ventilation.

Flurbiprofen axetil promotes neuroprotection by activation of cerebral peroxisome proliferator-activated receptor gamma after focal cerebral ischemia in rats.

Background: Our previous papers indicate that flurbiprofen axetil (FA), a cyclooxygenase inhibitor, is a promising therapeutic strategy for cerebral ischemia in rats. This study aimed to investigate whether FA could promote a neuroprotective effect by activation of peroxisome proliferator-activated receptor-γ (PPAR-γ) after focal cerebral ischemia in rats.

Methods: Totally 48 male Sprague-Dawley (SD) rats were randomly assigned into six groups (n = 8 in each group): animals in group ischemia/reperfusion (I/R) only received 120-minute transient middle cerebral artery occlusion (tMCAO); animals in group I/R + FA were administered FA (10 mg/kg) by caudal vein just after 120-minute tMCAO; animals in group I/R + FA + GW9662 were administered GW9662 (a PPAR-γ inhibitor, 1 mg/kg) intraperitoneally 30 minutes before cerebral ischemia onset and FA (10 mg/kg) by caudal vein just after 120-minute tMCAO; animals in group I/R + GW9662 were administered GW9662 (1 mg/kg) intraperitoneally 30 minutes before cerebral ischemia onset; animals in group I/R + DMSO were administered 3% DMSO (vehicle of GW9662, 1 ml/kg) intraperitoneally 30 minutes before cerebral ischemia onset; animals in sham group experienced the identical surgery apart from the insertion of the nylon filament.

Therapeutic time window of flurbiprofen axetil's neuroprotective effect in a rat model of transient focal cerebral ischemia.

Background: The neuroprotective effect of the cyclooxygenase (COX) inhibitor has been demonstrated in acute and chronic neurodegenerative processes. But its function under cerebral ischemic conditions is unclear. This study was designed to evaluate the neuroprotective efficacy of emulsified flurbiprofen axetil (FA, COX inhibitor) and its therapeutic time window in a model of transient middle cerebral artery occlusion (MCAO) in rats.
