Obstructive sleep apnea(OSA)is a dis-order characterized by chronic intermittent hypoxia and sleep fragmentation,usually manifested by ob-struction of the upper respiratory tract,resulting in sleep fragmentation,intermittent hypoxia,and hy-percapnia.OSA and significant comorbidities are as-sociated with perioperative complications.Opioids,as the most commonly used pain relievers,may fur-ther affect perioperative pain management in OSA and comorbidities.Studies have shown that OSA patients are more susceptible to the respiratory de-pressant effects of opioids.OSA also increases the risk of opioid-induced respiratory depression.There-fore,understanding the effects and mechanisms of opioids on OSA has important clinical significance for optimizing drug use,improving prognosis,and reducing respiratory adverse events.This article aims to review the effects of opioids on OSA and their relationship.

microRNA(miRNA)is a 22nt long sin-gle-stranded non-coding RNA that is involved in a variety of physiological and pathological processes.Bronchial asthma is a heterogeneous disease,and airway inflammation is one of the important mecha-nisms of its pathogenesis.Asthma can be classified into different types based on the different immune mechanisms involved in its pathogenesis,and the mechanism of airway inflammation also varies be-tween different types of asthma.This article reviews the research progress of miRNA in asthma airway inflammation and endotype,and explores the pathogenesis and treatment prospects of miRNA in asthma airway inflammation and endotype.

OBJECTIVE：To establish a method for concentration determination of anlotinib in human plasma and apply it in the clinic. METHODS ：The plasma samples were pretreated by salting-out assisted with liquid-liquid extraction with ammonium acetate as salting out assistant and acetonitrile as solvent. Using voriconazole as internal standard ，LC-MS/MS method was adopted. The separation was performed on Waters X Bridge C 18 column with mobile phase consisting of 0.2％ formic acid solution- acetonitrile（gradient elution ）at the flow rate of 1 mL/min. The column temperature was set at 40 ℃，and sample size was 10 μL. The split ratio was 3∶7. The electrospray ion source and multiple reaction monitoring mode were used for the analysis. The ion pair of anlotinib and internal standard under positive ion mode were m/z 408.3→339.3 and m/z 350.2→281.3，respectively. RESULTS ： Anlotinib showed a good linear relationship in the concentration range of 0.2-200 ng/mL（R2＞0.996 7）. The lowest limit of quantitation was 0.2 ng/mL. Intra-day and inter-day RSDs were no more than 12％ （n＝6 or n＝3）. Accuracies were 90.92％-108.00％（n＝6 or n＝3）. The average extraction recoveries were 87.51％-100.00％（RSD＜8％，n＝6）. The average matrix effects were 96.66％-99.93％（RSD＜5％，n＝6）. The plasma concentration of 3 patients with NSCLC treated with anlotinib was 8.74-65.60 ng/mL. CONCLUSIONS ：The method is simple ，accurate and specific ，and is suitable for the plasma concentration monitoring of anlotinib in NSCLC patients.
