Objective:To evaluate the relationship between the effect of microlaryngoscopic surgery of vocal polyp and the change of all-parameters.Method:Acoustic parameters of 80 patients with vocal polyp were measured by Dr .Speech Sciente for Windows, and analyzed preoperatively and postoperatively.Result:The jitter, shimmer and NNE were different significantly between preoperative and postoperative,the NNE and shimmer were more sensitive than jitter.Conclusion:The NNE and shimmer of acoustic parameter are objective parameter to evaluate the effect of the microlaryngoscopic surgery of vocal polyp.

{L-End}Objective To understand the influence of job burnout and anxiety symptoms on work ability of biosafety laboratory (BSL) workers in Xinjiang Uygur Autonomous Region. {L-End}Methods A total of 5 808 BSL workers in Xinjiang Region were selected as the research subjects using cluster sampling method. The Job Burnout Questionnaire, Anxiety Self-rating Scale and Work Ability Index Questionnaire were used to evaluate their job burnout, anxiety symptoms and work ability. The mediation effect of anxiety symptoms on the relationship between job burnout and work ability was tested by stepwise regression analysis. {L-End}Results The detection rate of job burnout, anxiety symptoms and poor working ability was 83.1% (4 829/5 808), 37.2% (2 160/5 808) and 5.8% (339/5 808), respectively. There was a positive correlation between job burnout and anxiety symptoms score in BSL workers [correlation coefficient (r) was 0.48, P<0.01]. The score of job burnout and anxiety symptoms was negatively correlated with the work ability score (r were -0.58, -0.51, both P<0.01). The results of mediation effect analysis show that the total effect of job burnout on work ability was -0.31, with the direct effect of -0.15. The mediation effect of anxiety symptoms on the relationship between job burnout and work ability was -0.16, accounting for 51.6% of the total effect. {L-End}Conclusion The detection rates of job burnout and anxiety symptoms among BSL workers in Xinjiang Region are relatively high. Anxiety symptoms show a mediate effect on the relationship between job burnout and work ability. The work ability of BSL workers can be improved by improving job burnout and anxiety symptoms.

The principle of human respiratory function test is decleared. The innovative testing parameters is proposed to optimize traditional calculation parameters based on a respiratory function test of one-time max respiratory flow and pressure. The parameters of respiratory function evaluation was preliminarily verified, and we have already got the expected experimental result. The research can be a valuable reference for the following respiratory function test in future.

OBJECTIVETo investigate the effects of Xinfeng Capsule (XFC) on pulmonary function and related mechanism in adjuvant-induced arthritis (AA) rats.
METHODSThe rats were randomly divided into five groups: normal control (NC), model control (MC) groups, methotrexate (MTX), tripterygium glycosides tablet (TPT) and Xinfeng capsule (XFC) treatment groups. The adjuvant-induced arthritis model was established by intracutaneous injection of 0.1 mL Freund ' s complete adjuvant in the right paw of rats; the drugs were given 19 d after model establishment. The toe swelling degree (E), arthritis index (AI), pulmonary function, peripheral blood Treg levels, pathological changes of lung tissue and expression of Foxp3, TGF-β1, Smad3, Smad7 proteins in lung tissue were measured 30 d after drug administration.
RESULTSCompared to NC group, the levels of E, AI, alveolitis score, TGF-β1 and Smad3 were significantly increased (P <0.05 or P <0.01); maximum expiratory flow 25% of vital capacity (FEF25),50% maximal expiratory vital capacity flow (FEF50), maximum expiratory flow at 75% of vital capacity (FEF75), maximum mid-expiratory flow (MMF), force peak expiratory flow (PEF), CD4+ CD25+ Treg, Foxp3 and Smad7 were significantly decreased in MC group (P <0.05 or P < 0.01). Compared to MC group,the expression of E, AI, TGF-β1 and Smad3 were reduced, while FEF50, FEF75, MMF, PEF, Treg, Foxp3 and Smad7 were elevated in XFC group (P <0.05 or P <0.01). Compared to XFC group, the level of body mass,FEF25,FEF50, FEF75, MMF and Treg were lower in MTX and TPT groups (P <0.05 or P <0.01).
CONCLUSIONThere are inflamed joints and reduced pulmonary function in rats of adjuvant-induced arthritis. XFC can inhibit paw edema degrees, reduce arthritis response, and improve pulmonary function, which is associated with up-regulating expression of Treg and Foxp3, down-regulating the expression of TGF-β1 and adjusting TGF-β1/Smads signal pathway.

Objective:
The aim of this study is to investigate the effect of fibreoptic endoscopic of sallowing (FEES) in the assessment of pharyngeal dysphagia in post-irradiated patients with nasopharyngeal carcinoma.
Method:
Fifty-three NPC patients with post-irradiated underwent FEES and video fluoroscopy(VF).The results were analyzed using the Bolus Residue Scale and Rosenbek's penetration aspiration scale.
Result:
The agreement in the detection of penetration and aspiration between FEES and VF of liquid(κ=0.56, 95%CI 0.38-0.73) and porridge(κ=0.64, 95%CI 0.43-0.81) was "fair". The detection rates of penetration on FEES with liquid and porridge were 60% and 51%, the detection rates of aspiration on VF with liquid and porridge were 70% and 53%. There were no statistical differences. The agreement in the detection of pharyngeal residue between FEES and VF of liquid (κ=0.38, 95%CI0.12-0.62) and porridge (κ=0.66, 95%CI 0.44-0.86) was "fair". The detection rates of pharyngeal residue on FEES and VF with porridge were 43% and 45%, the difference was not statistically significant. The detection rates of pharyngeal residue on FEES and VF with liquid were 44% and 24%, and the difference was statistically significant.
Conclusion
FEES is an effective and valuable tool for evaluating pharyngeal dysphagia in post-irradiated patients with nasopharyngeal carcinoma.
