[Characteristics of air-conducted and bone-conducted vibration cervical vestibular-evoked myogenic potential in preschool children].

To investigate the characteristics of air-conducted sound cervical vestibular evoked myogenic potential （ACS-cVEMP） and bone-conducted vibration cervical vestibular evoked myogenic potential （BCV-cVEMP） in healthy preschool children, and to provide the normal reference range of VEMP for preschool children in China. Forty-four normal-hearing children （88 ears） aged 3-7 years were recruited to undergo ACS-cVEMP and BCV-cVEMP determination. These children were divided into two groups according to age: 3-4 years old group （ 17 cases, 34 ears） and 5-7 years old group （ 27 cases, 54 ears）.

[Arousal characteristics in different OSAHS populations].

This study sought to explore the effect of age on arousal index in patients with OSAHS, and the significance of arousal index among different phenotypes identified through cluster analysis according to clinical symptoms and complications. A total of 607 adult patients with OSAHS who received polysomnography in the Second Affiliated Hospital of Xi'an Jiaotong University from July 2020 to July 2021 were selected. All patients registered basic human data, symptoms, complaints and complications, completed the Epworth Sleepiness Scale.

[Study on changes of nasal resistance based on 3D printing transparent nasal cavity models].

To investigate the causal relationship between the minimum cross-sectional area of nasal cavity and nasal resistance. Thirty transparent detachable 3D printing nasal cavity models were made. The airway was completely blocked with sealing material at different anatomical sections.

NB-UVB Induces Melanocytic Differentiation of Human Hair Follicle Neural Crest Stem Cells.

Background: Phototherapy is an important method to treat vitiligo. However, it is unclear how phototherapy affects melanocyte precursors and skin neural crest stem cells.

Objective: To investigate the underlying mechanisms of narrow-band ultraviolet B (NB-UVB) induced melanocyte lineage differentiated from human scalp-derived neural crest stem cells (HS-NCSCs).

Effect of Desflurane versus Sevoflurane in Pediatric Anesthesia: A Meta-Analysis.

Purpose: To compare the effect of desflurane versus sevoflurane in pediatric anesthesia by conducting meta-analysis.

Methods: Studies were searched from PubMed, Medline, Springer, Elsevier Science Direct, Cochrane Library and Google Scholar up to July 2014. Weighted mean difference (WMD) or risk ratio (RR) and 95% confidence intervals (CIs) were considered as effect sizes.
