Objective To explore the clinic value of the vocal acoustics on voice evaluation in larynx leukoplakia pa?tients. Methods Dr. Speech software was used to perform voice acoustic analysis and deduce EGG parameters in 48 sub?jects with larynx leukoplakia and 50 normal subjects. Voice acoustic analysis parameters (Jitter, Shimmer, NNE, HNR, SNR, MPT), EGG parameters ( EGG-Jitter、EGG-Shimmer、EGG-NNE、EGG-HNR、EGG-SNR, CQP,CIP) and EGG wave?form were compared between two groups. Results For voice acoustic analysis, Jitter, Shimmer, NNE in larynx leukoplakia group were higher than those in normal group while HNR, SNR in larynx leukoplakia group were lower than those of normal group. What’s more,MPT in larynx leukoplakia group was obviously shorter than that in normal group with, statistically sig?nificant difference (P<0.05). For EGG analysis, EGG-Jitter, EGG-Shimmer, EGG-NNE were higher in larynx leukoplakia group than those in normal group with significant difference (P<0.05). EGG-HNR and EGG-SNR in larynx leukoplakia group were lower than those in normal group. Furthermore, CQP and CIP in larynx leukoplakia group were higher than those normal group with statistically significant difference (P<0.05). Most patients’(72.9%) EGG waveform showed gradually ac?celerate phase velocity and fast close phase, which represent a spike-like shape. Conclusion Voice acoustic analysis com?bined with EGG provide objective indicators to assess degree of hoarseness, and to provide sonic evidences for prevention, recurrence, assessment and pronunciation correction of the larynx leukoplakia.

OBJECTIVE To investigate the effect of obstructive sleep apnea hypopnea syndrome(OSAHS) on the quality of voice. METHODS Electroglottography (EGG) method was used for detecting the vocal cords vibration, waveforms of electroglottography and voice parameters such as Jitter, Shimmer, normalized noise energy (NNE), contact quotient(CQ), contact index (CI), contact quotient perturbation(CQP), contact index perturbation(CIP), and the in 82 OSAHS patients and 53 healthy subjects. The voice parameters were analyzed with Dr.Speech software, RESULTS While in normal pronunciation, the Jitter, Shimmer, NNE, CQP and CIP were (1.037±1.493)%, (5.627±1.872)%, (-16.109±1.719)dB, (2.638±0.633)% and (166.789±30.492)% in 22 mild OSAHS patients, (1.578±0.362)%, (8.478±1.635)%, (-11.517±1.614)dB, (6.043±0.936)% and (255.210±91.224)% in 24 moderate OSAHS patients, and (2.138±1.384)%, (14.888±4.089)%, (-7.677±2.151)dB, (11.749±7.164)% and (431.233±259.266)%in 36 severe OSAHS patients respectively. They were all higher than those in 53 normal subjects as (0.517±0.303)%, (3.299±2.196)%, (-21.933±5.477)dB, (1.322±0.942)% and (58.834±131.849)%. The regularity of vocal fold vibration in all patients with OSAHS was seriously out of whack. EGG waveform was irregular. CONCLUSION The OSAHS patients have structural changes in their upper airway, it will cause non-physiological breathing and lead dry of the vocal cord mucosa and weak elasticity. Their EGG parameters will get higher and vibration will be irregular seriously. We should pay attention to the voice qualities of the OSAHS patients and let them receive treatment as early as possible.

Objective: To explore the longitudinal association of the levels of plasma irisin among children with changes in obesity related parameters and newly onset obesity, and to explore whether physical activity (PA) and sedentary behavior(SB) have regulatory effects, to provide a scientific basis for the prevention and control of childhood obesity work. Methods: Cluster random sampling method was used to select 521 children from five schools in Guangzhou in 2017 at baseline and were followed up in 2019. A based on baseline PA and SB, children who meet the following criterion were selected:moderate vigorous intensity PA≥60 min/d or <150 min/week; and gender , age specific SB≥ P 75 or SB < P 25 . Plasma irisin concentration was measured in all the selected children. Multiple linear regression and Logistic regression were conducted to analyze the association. Results: The two year cumulative incidence of obesity, overweight and obesity, and central obesity was 2.82%, 6.57%, and 6.81%, respectively. There was no statistically significant association between plasma irisin levels and changes in obesity related parameters, newly onset overweight obesity or central obesity among children ( P >0.05). After stratified by PA, the irisin concentration in the low PA group was positively associated with weight change ( B=0.229, P =0.03). After stratified by SB, the irisin concentration in the low SB group was positively associated with the height change ( B=0.210, P <0.05). In addition, PA level and SB level both had a moderating effect on the association between plasma irisin levels and the weight change ( P PA=0.01, P SB =0.05). Conclusion PA and SB show moderating effect on plasma irisin concentration and weight gain. No association of irisin concentration with newly onset overweight or obesity among children has been found.
