[Histological changes after the recontruction of tongue defect with rectus abdominis musculoperitoneal flap].

Objective: To observe the cellular morphological and histological changes of the reconstructed tongue defect by rectus abdominis musculoperitoneal flap of dogs with or without nerve.

Methods: 12 Beagle dogs were randomly divided into two groups. Group A made rectus abdominis musculoperitoneal flap with the intercostal nerve while group B without the intercostal nerve.

[Changes of high-sensitivity CRP and insulin sensitivity index in children with obstructive sleep apnea hypopnea syndrome].

Objective: To investigate the levels of high-sensitivity CRP (hsCRP) and insulin sensitivity index (ISI) in children with obstructive sleep apnea hypopnea syndrome (OSAHS).

Methods: Twenty-nine children with OSAHS and 22 children with primary snoring (PS) were enrolled. Polysomnography was performed.

[Prevalence of upper respiratory tract group A Streptococcus carriage in school-age children from Tulufan City and Buerjin County of Xinjiang Province].

Objective: To study the prevalence rate of upper respiratory tract group A Streptococcus (GAS) carriage in school-age children from Xinjiang Province.

Methods: A total of 478 children at age of 9-12 years from Tulufan City and Buerjin County of Xinjiang Province were enrolled by random cluster sampling. Throat swab cultures were performed once each season for the determination of presence of GAS.

[Diagnostic values of serum orexin-A levels in children with obstructive sleep apnea-hypopnea syndrome].

Objective: Currently people regard polysomnography (PSG) monitoring as the golden standard for diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS) in children. However, due to the high cost, time and manpower consuming, PSG is not applicable to epidemiological investigation and clinical screening, especially not suitable for child patients and remote hospitals in Xinjiang. Therefore, it is of important clinical significance to find out a simple method (e.

[Protection of azithromycin against pulmonary II epithelial cell injuries induced by cigarette smoke extract and relevant mechanisms].

Objective: Cigarette smoke extract (CSE) can induce injuries of pulmonary II epithelial cells, activate nuclear factor-kappaB and increase tumor necrosis factor-alpha(TNF-alpha) secretion. This study aimed to investigate whether azithromycin can protect pulmonary II epithelial cells from injuries induced by CSE and relevant mechanisms.

Methods: Pulmonary II epithelial cells (A549 cells) were cultured in vitro.
