Objective To observe the influence of post-operative swallowing painwith Disposcope endoscope or Macintosh laryngoscope in patients with difficult visible glottis. Methods Thirty-six patients scheduled for elective surgery under general anesthesia whose glottis was not visible underMacintosh laryngoscope (according to Cormach-Lehane Grading of laryngoscopic view) were randomized into 2 groups (n = 18 each):Disposcope endoscope group (group D) and Macintosh laryngoscope group (group M). The rate of glottis exposure and successful intubation, swallowing pain at 30 min, 1, 3 d after extubation were observed. Results Compared with group M , the successful rate of glottis exposure and first intubation was significantly higher than thatin group D (P < 0.05). Swallowing pain VAS was higher in group M than in group D at 1d afterextubation (P < 0.05). Conclusions Compared with Macintosh laryngoscope , Disposcope endoscope in patients with difficult visible glottis could induce higher successful rate of glottis exposure and first intubation , shorter time of intubation and lower VAS of swallowing pain at 1d after extubation.

Objective To investigate the relationship between the education level of staff members and the risk factors for stroke in a university in China.Methods From January 2014 to May 2014,a total of 659 staff members in a university in China were collected with a cluster sampling method.The basic information and the relevant data of the risk factors for stroke of the subjects were collected and recorded completely.The subjects were divided into 3 groups according to their education levels from low to high.The relationship between their education levels and the risk factors for stroke were analyzed.Results A total of 633 staff members were enrolled,including 426 men (67.3％) and 207 women (32.7％).The low,middle and high education level groups were 188 (29.7％),193 (30.5％),and 252 (39.8％),respectively.With the increase of the education level,the prevalence of hypertension,dyslipidemia,and stroke decreased,and the awareness rates of hypertension and dyslipidemia and the treatment rate increased.The proportion of drink-ing increased in the male group and that decreased in the female group.The proportion of regular exercise increased in the female group.Multivariate logistic regression analysis showed that after adjusting for age,per capita income,employment,drinking,smoking,regular exercise and other factors,compared with the high education level group,the risk of hypertension increased 2.55 times in the low education level group in males (odds ratio [OR] 2.55,95％ confidence interval [CI] 1.42-4.58;P =0.002);the prevalence risk of dyslipidemia increased 2.25 (OR 2.25,95％ CI 1.31-3.86;P =0.003) and 2.02 times in the low and middle education level groups (OR 2.02,95％ CI 1.23-3.33;P =0.006) respectively;the risk of smoking decreased 42％ in the middle education level group (OR 0.58,95％ CI 0.36-0.93;P =0.024);the risk of hypertension increased 6.27 times in the low level education group in women (OR 6.27,95％ CI 1.59-24.74;P =0.009);the risk of dyslipidemia increased 3.91 times in the middle education level group (OR 3.91,95％ CI 1.70-8.98;P =0.001);the risk of drinking increased 3.49 times in the low level education group (OR 3.49,95％ CI 1.12-10.92;P =0.032),and the weekly regular exercise decreased 65％ in the low level education group (OR0.35,95％ CI0.15-0.82;P =0.016).Conclusion The incidence of the risk factors for stroke in the low education level group was higher than the popuhtions of high or middle education level.
