To study the role of boswellic acid in reducing asthma phenotype severity and the relationship between the expression of pSTAT6 and GATA3, thirty-six mice were randomly divided into normal control group, asthma group, and boswellic acid group (treatment group). The asthma model was established through an intraperitoneal injection of sensitization liquid (0.15 mL aluminum hydroxide gel at 88.67 mg/mL and 0.05 mg ovalbumin). pSTAT6 and GATA3 expression levels in peripheral blood were detected by reverse transcription-polymerase chain reaction and Western blot analysis. pSTAT6 and GATA3 gene expressions in the asthmatic group were significantly higher than in the normal control group; they were markedly lower in the treatment group than the asthma group, and there was no significant difference when compared with the normal control group. ⋯ GATA3 expression had a positive correlation with pSTAT6 expression. Boswellic acid may improve asthma symptoms by inhibiting pSTAT6 expression, which consequently reduces GATA3 expression.

This study aimed to discuss the effects of 3 different analgesia methods on serum IL-6 and IL-10 in patients after cesarean delivery. Thirty full-term women, who underwent cesarean delivery, were randomly assigned to 3 analgesia groups (10 cases each) as follows: intramuscular injection of 100 mg pethidine (NC group), patient controlled epidural analgesia (PCEA) of 5 mg morphine plus 150 mg ropivacaine (MR group), and patient controlled intravenous analgesia (PCIA) of 150 mg sufentanil plus 5 mg droperidol (SF group). An electronic analgesia pump was available in all 3 groups. ⋯ In the MR and SF groups, no significant difference occurred at each time point (P > 0.05), but compared with the NC group, significant differences were observed at 12 and 24 h (P < 0.05). Both PCIA and PCEA produced good analgesic effect, decreased postoperative level of serum IL-6, promoted release of anti-inflammatory factor IL-10, maintained balance in postoperative serum IL-6 level, and reduced the postoperative inflammatory response. Adverse reactions were significantly higher with epidural morphine than with intravenous sufentanil.

Trigeminal neuralgia is a sudden, severe condition characterized by stabbing and recurrent pain. Radiofrequency thermocoagulation (RFT) and pulsed radiofrequency (PRF) are common surgical interventions used to treat trigeminal neuralgia. This study aimed to investigate the therapeutic effects and associated complications of a combination of RFT and PRF in the treatment of trigeminal neuralgia. ⋯ Data showed that facial numbness and postoperative masticatory muscle weakness recovered more rapidly in patients receiving combined RFT and PRF treatment. Decreased corneal reflex was relieved to a significantly greater extent in groups receiving PRF than those without. Thus, compared to the use of RFT at 75°C alone, the combination of PRF and RFT helped eliminate postoperative complications, such as facial numbness, masticatory muscle weakness, and decreased corneal reflex, indicating that it could be useful for surgically treating trigeminal neuralgia.

The aim of this study was to determine the effect of etomidate and propofol pretreatment on the expression of glucocorticoid receptor and the prognosis of sepsis. The sepsis rat was used as a model. During glucocorticoid treatment, etomidate and propofol were applied alone or together at different time points. ⋯ Etomidate was best used immediately after modeling, whereas propofol was most suitable for use during the peak inflammatory reaction. These results demonstrated that anesthetics had the ability to enhance the effect of glucocorticoids in the treatment of sepsis. Etomidate was indicated for use in the early stage of inflammation to enhance expression of the glucocorticoid receptor, while propofol application was indicated at the peak of the inflammatory reaction owing to its strong anti-inflammation effect.

Remifentanil (an ultra-short acting μ-opioid receptor agonist) use has been associated with acute opioid tolerance and hyperalgesia. Previous electrophysiological studies have shown that remifentanil elicits rapid and prolonged upregulation of N-methyl-D-aspartate receptor (NMDAR) currents. However, the effect of remifentanil on the levels of the GluN1 subunit of the NMDAR in dorsal horn neurons (DHNs) has not been reported. ⋯ GluN1 mRNA and protein levels, determined by real time reverse transcription polymerase chain reaction (RT-PCR) and Western blot, respectively, were significantly and persistently increased by remifentanil exposure compared with the control group (P ＜ 0.05). These results may partially account for the mechanism of remifentanil-induced hyperalgesia. This increase was prevented by ketamine (NMDAR antagonist) and naloxone (μ-opioid receptors antagonist), thus providing a potential therapeutic mechanism for the prevention of opioid-induced hyperalgesia.
