Chinese Journal of Anesthesiology 2014;34(z1):71-73
Objective To investigate the effects of preoperative sleep disturbance on the efficacy of flurbiprofen for postoperative analgesia in patients undergoing endoscopic nasal surgery.Methods Ninety-six ASA Ⅰ or Ⅱ patients of both sexes (aged 20-60 years and weighing 50-80 kg) undergoing endoscopic nasal surgery were enrolled in this study.Pittsburg sleep quality index was used to evaluate the long-term sleep quality before hospitalization and Athens sleep quality index was used to evaluate the short-term sleep quality in hospital.The patients were divided into four groups according to the types of preoperative sleep disturbance (n =24 each):no sleep disturbance (group Ⅰ),long-term sleep disturbance (group Ⅱ),acute short-term sleep disturbance (group Ⅲ),and long-term + acute short-term sleep disturbance (group Ⅳ).Anesthesia was induced with sufentanil,propofol and cis-atracurium and maintained with intravenous infusion of remifentanil and propofol.Then the patients received endotracheal intubation and mechanical ventilation.The end-tidal pressure of carbon dioxide was maintained at 30-35 mm Hg.Controlled hypotension was performed with nicardipine,and the mean arterial blood pressure was maintained at 50-70 mm Hg and heart rate at 60-90 bpm during operation.The patients received intravenous injection of flurbiprofen 50 mg 15 minutes before the end of operation for postoperative analgesia.When the visual analogue scale score was more than 3 during the first 6 hours after operation,flurbiprofen 50 mg was given intravenously as rescue analgesia.Results The incidence of rescue analgesia administered after operation was significantly greater in groups Ⅱ,Ⅲ and Ⅳ than in group Ⅰ,and greater in group Ⅳ than in groups Ⅱ and Ⅲ.There was no significant difference in the incidence of rescue analgesia administered during the first 6 hours after operation between groups Ⅱ and Ⅲ.Conclusion Preoperative sleep disturbance has adverse effects on the efficacy of flurbiprofen for postoperative analgesia in patients undergoing endoscopic nasal surgery.

Objective To study the effects of hypothermia therapy on inflammation level and safety of patients with severe nervous injury.Methods A total of 82 patients with severe nerve injury were divided into study group and control group by random digits table, 41 patients in each group.The patients in these two groups had no statistical dis-parities in inflammatory agent and intracranial pressure (p>0.05).The patients in the control group were treated by routine therapy and those in the study group were treated by cephalic hypothermia therapy additionally.The two groups were compared in terms of the level of TNFα, IL-6 and IL-8 in the cerebrospinal fluid, prognosis and safety.Re-sults Before treatment there was no significant difference in inflammation level between the two groups (p>0.05). After treatment, the TNFα, IL-6 and IL-8 levels in the study group were significantly lower than those in control group (p<0.01).Before treatment there was no significant difference in ICP between two groups (p>0.05).How-ever, after treatment there was a significant difference in ICP between the two groups in all time points (p<0.01). The GOS score in the study group was significantly lower than that in the control group.There was no statistical dis-parities in complications between the two groups (p>0.0).Conclusion The hypothermia therapy has a great clini-cal efficacy and safety on severe never injury patients, which makes it worth clinical application.

Objective To study the effect of oxymatrine on p-STAT3 and PIAS3 signaling molecule and it's mRNA expression in the proliferation of the human mesangial cells (HMCs) induced by lipopolysaccharide(LPS) and to explore their relationship. Methods HMCs were divided into three groups: control group, LPS group and oxymatrine group. HMC proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay. Type Ⅳ collagen in the supernatants of the cultured HMCs was detected by ELISA at 12, 24, 48 hours respectively. At the same time, the protein and mRNA expressions of p-STAT3 and PIAS3 were measured by Western blot and real-time quantitative RT-PCR. Results The cell proliferation, the mRNA and protein expression of type Ⅳ collagen, p-STAT3 in LPS group were increased compared with the control group (P<0.01), but they were decreased in oxymatrine group (P < 0.01). The expressions of protein and mRNA of PIAS3 in LPS group were decreased significantly compared with control group (P<0.01), but they were increased in oxymatrine group (P<0.01). Conclusion Oxymatrine can down-regulate the expression of p-STAT3 and up-regulate the expression of PIAS3, which plays an important role in the process of LPS-induced HMCs proliferation.

Brain-derived neurotrophic factor (BDNF) can promote developmental competence in mammalian oocytes during in vitro maturation (IVM), but the role of BDNF in oocyte maturation at cellular level is not still clear. In this study, mouse cumulus-enclosed oocytes subjected to IVM were fertilized and cultured to blastocyst stage. Meiotic spindle configuration and cortical granules distribution during oocyte maturation in vitro were assessed by using immunofluorescence and laser confocal microscopy. The results showed that BDNF contributed to the complete preimplantation development of mouse oocytes compared to the control oocytes (13.78% vs. 5.92%; P<0.05). Further, BDNF did not accelerate nuclear maturation of IVM oocytes. For the BDNF-treated oocytes at meiosis I, Meiotic spindle areas were significantly smaller and the number of cytoplasmic microtubule organizing centers was greater than that in the control, and the percentages of oocytes showed spindles positioned near the oolemma and a well-formed cortical granule-free domain were significantly higher than that of the control. These morphological characteristics of the BDNF-treated oocytes were much closer to the oocytes matured in vivo than those of the control oocytes. In conclusion, BDNF can promote the developmental competence of mouse IVM oocytes, by improving the meiotic spindle configuration and location and cortical granules distribution at meiosis.
