Objective To investigate the role of airflow parameters of some specific examinations in voice function assessment.Methods The s/z ratio, pulmonary function and phonatory aerodynamic parameters were measured in subjects with benign vocal fold lesions and with normal voice.The effect of treatment in subjects with benign vocal fold lesions was evaluated with the phonatory aerodynamic parameters.Results The value of s/z ratio in the disease group was higher than that in the normal group (P ＜ 0.05).The value of PEF was significantly different between the disease group and the normal group fur male(P ＜0.05).MFR, MPT, PTF, SGP, PTP, VE were significantly different between the disease group and the normal group(P ＜0.05).MFR, MPT, PTF, SGP, PTP of the disease group after surgery for both sex were significantly different from before surgery (P ＜ 0.05).The disease group was subdivided into two groups through stroboscopic examination before and one month after surgery: the worse group (with some functional laryngeal abnormality, or organic abnormality except benign vocal fold lesion)and the better group.PTF, PTP, SGP, VE were significantly different between the worse group and the normal voice group.There was almost no significant difference for aerodynamic parameters between the better group and the normal voice group (P ＞ 0.05).There was no significant difference between the worse group after 8 weeks'voice training and the normal voice group (P ＞ 0.05).Conclusions s/z ratio, aerodynamic parameters (MFR, MPT, SGP, PTF, PTP, VE) are valuable for the diagnosis and assessment of the voice disorders.Aerodynamic parameters are sensitive to the change of glottal function during the treatment.Voice training can increase the glottal function of patients after laryngeal microsurgery.

Objective To construct a hospital glucose monitoring standardized management model and to evaluate its effectiveness.Methods Established standardized hospital glucose monitoring management team to develop responsibility and work plan, to assess training and quality control of hospital glucose monitoring standardized management mode regularly.From June 2012 to June 2013, the standardized management was implemented, the questionnaires were conducted before and after the standardized management, on-site inspection and operational assessment were given.Results After the implementation of hospital standardized management mode, 442 nurses gained the knowledge mastery of POCT glucose monitoring from (35.54 ±7.96) points to (87.24 ±4.27) points.The achievement of 37 liaisons in hospital blood glucose monitoring standardized group has risen from(59.65 ±5.22)points to(91.69 ±4.38)points in one year.The quality control results from 38 departments who possess POCT have risen from(52.34 ±6.85) points to(95.47 ±4.62) points in one year. And the differences were statistically significance ( t =120.33, 28.60, 32.18, respectively;P <0.01 ). Conclusions Hospital glucose monitoring standardizes management mode standardizes the management of blood glucose monitoring, improves liaisons’ and hospital nurses’ mastery of blood glucose monitoring.

Objective: To discuss the clinical effect of small dose of botulinum toxin injection in cricothyroid muscle and thyroarytenoid muscle on patients with incomplete bilateral recurrent laryngeal nerve paresis. Methods: Six patients were selected with Ⅰor Ⅱ or Ⅲ degree of dyspnea diagnosed as bilateral recurrent laryngeal nerve injury by laryngeal electromyography, and small dose of botulinum toxin injection was performed in cricothyroid muscle and thyroarytenoid muscle as a treatment. Degree of dyspnea was assessed one month before and after the treatment, and the stroboscopic laryngoscope results, acoustic parameters and CT image of the patients were collected in the 6 patients. The relevant parameters were also collected one month before and after treatment, including the degree of dyspnea, stroboscopic laryngoscope results, acoustic parameters and CT image of the patients. The angle between bilateral vocal cords in stroboscopy at full inspiratory was calculated, acoustic parameters (F0, jitter, shimmer) were analysed, and vocal length, width and the vocal region were measured. Then, the paired t test was performed for statistical analysis between before and after one month injection, the one way analysis of variance was performed among vocal parameters in CT image. Result: Botulinum toxin injection was successfully completed in the 6 patients, followed without any serious complications. The degree of dyspnea was alleviated to some extent after treatment in all 6 patients; the angle between bilateral vocal cords at the end of a deep inspiration was significantly increased (t=2.44, P<0.05) after the treatment. The changes of F0 and jitter between before and after treatment were not statistically significant (t=0.72, t=1.42, P>0.05). Shimmer was significantly decreased after treatment (t=2.61, P<0.05). Vocal fold length, width and vocal region increased with F0, there was a statistically significant difference between different F0 before injection, and there was no statistically significant difference between different F0 after injection. The follow-up time was respectively seven months, 1 year, 1 year, 18 months, 22 months and 2 years respectively. Conclusion Small dose of botulinum toxin injection in bilateral cricothyroid muscles and thyroarytenoid muscles can relieve the dyspnea caused by bilateral vocal cords paresis to some extent, accompanied without serious complications, despite the sound quality was slightly worse.
