Objective To investigate the role of neuroglobin ( NGB) in oxygen-glucose deprivation and reoxygenation ( OGD/R ) induced mitochondrial depolarization and reactive oxygen species ( ROS ) production in a human neuroblastoma cell line (SH-SY5Y).Methods SH-SY5Y cells were transfected with lentivirus to establish a stable cell line of NGB knockdown ( KD).After treated with OGD/R, cells were collected at different time points to analyze NGB mRNA and protein levels.Furthermore, cells were stained with JC-1 and DCFH-DA to evaluate mitochondrial depolarization and ROS production by inverted fluorescence microscope.Also, to determine the neurotoxicity , we measured the lactate dehydrogenase ( LDH) level in the cell culture medium.Results After the treatment of OGD/R, the NGB mRNA and protein started to elevate and peak at 4 h and 8 h (2.04 ±0.35 fold,1.69 ±0.18 fold).Compared with the vector group , NGB KD group had much more mitochondrial depolarization [ JC-1 red/green ( 1.10 ±0.10 ) vs (1.46 ±0.11),P<0.05] and ROS production [DCFH-DA fluorescence (36.30 ±5.32) vs (16.26 ± 2.97),P<0.05].Furthermore, NGB KD groups had a higher level of LDH release [(63.42 ±6.14)%vs (49.65 ±5.09 )%, P <0.05 ].Conclusions NGB plays an important role in the homeostasis of mitochondria.Knockdown of NGB results in increased mitochondrial depolarization , ROS production and neurotoxicity under hypoxia circumstances.

INTRODUCTIONPostoperative nausea and vomiting (PONV), and postoperative pain are common during the early postoperative period. In addition to these problems, elderly patients risk developing postoperative confusion. This study aimed to identify the risk factors associated with these problems, and the extent of these problems, in a Singapore inpatient surgical population.

METHODSOver a period of six weeks, we surveyed 707 elective surgical inpatients aged ≥ 18 years who received general anaesthesia and/or regional anaesthesia.

RESULTSThe incidence of PONV was 31.8% (95% confidence interval [CI] 34.8-41.9). The incidence increased with increasing Apfel score (p < 0.001) and were higher in female patients (odds ratio [OR] 1.74, 95% CI 1.28-2.36), non-smokers (OR 1.72, 95% CI 1.04-2.88), patients with a history of PONV and/or motion sickness (OR 3.45, 95% CI 2.38-5.24), patients who received opioids (OR 1.39, 95% CI 1.03-1.88), and patients who received general anaesthesia (OR 1.76, 95% CI 1.11-2.79). Moderate to severe pain at rest and with movement were reported in 19.9% and 52.5% of patients, respectively. Among the patients who were predicted to experience mild pain, 29.5% reported moderate pain and 8.1% reported severe pain. The prevalence of postoperative confusion was 3.9% in the geriatric population.

CONCLUSIONHigher Apfel scores were associated with a higher risk of PONV and multimodal treatment for postoperative pain management was found to be insufficient. The incidence of postoperative confusion was low in this study.
