Objective To evaluate the efficacy of topical anesthesia with inhaled aerosolized lidocaine during tracheal intubation under the guidance of fiberoptic bronchoscopy (FOB) in patients with cervical cord injury complicated with high paraplegia. Methods Sixty-four patients with cervical cord injury complicated with high paraplegia were randomly divided into 2 groups ( n = 32 each): group Ⅰ aerosol inhalation and group Ⅱ spray and cricothyroid membrane puncture. In group Ⅰ aerosolized 2% lidocaine was inhaled. In group Ⅱ after the pharynx and larynx was sprayed with 2% lidocaine, cricothyroid membrane puncture was performed and then 2% lidocaine 2 ml was injected. Midazolam 0.01 mg/kg and fentanyl 1 μg/kg were injected iv in both groups 15 min before tracheal intubation guided by FOB. During tracheal intubation guided by FOB, the intubation condition was assessed, and MAP, HR, ECG and SpO2 were monitored. Results The satisfactory rate of intubation condition and success rate of intubation under the guidance of FOB were significantly higher, and the incidences of arrhythmia and bad memory lower in group Ⅰ than in group Ⅱ ( P < 0.05). Conclusion The topical anesthesia with inhaled aerosolized 2% lidocaine is helpful for improving the FOB-guided tracheal intubation condition, and can reduce the occurrence of adverse effects in patients with cervical cord injury complicated with high paraplegia.

Objective To explore the real ear to coupler difference (RECD) changes in children with hearing aids .Methods 132 severe to profound hearing impaired children who came to hearing center for hearing aids exami-nation and adjustment were recruited into the study .They were put into 6 groups according to the test age ,<1 yr group(15 cases) ,1 yrs group(26 cases) ,2 yrs group(36 cases) ,3 yrs group(29 cases) and 4 yrs group(26 cases) . And all of them had the RECD tests for both ears with custom earmolds .Results The average RECDs for both ears decreased with the age increased .There were statistically differences for the same lateral ears when age differences surpass 2 years except for the difference for left ears between the children in the <1 yr group and 2 yrs group .This study showed there were statistically differences between left and right ears for majority of groups (except for 2 yrs group) .Conclusion RECD is an important factor for individual adjustment .The current results show that the chil-dren with hearing aids should have RECD tests for both ears at least once per two years .

Objective To study the correlation between laryngopharyngeal reflux (LPR) and voice disorders . Methods One hundred and three patients with reflux -related symptoms were recruited .The patients were evalu-ated with reflux symptom index (RSI) ,reflux finding score (RFS) evaluation and 24-hour dural-probe pH moni-toring .Eighty -nine cases with voice disorders were divided into 5 groups :vocal process granuloma (n=18) chron-ic pharyngolaryngitis (n=19) ,vocal polyps (n=15) ,vocal fold leukoplakia (n=21) and Reinke's edema (n=16) . The other 14 patients without voice disorders were the control subjects .Results According 24-hour dural -probe pH monitoring assessments ,48 .3% of the patients with voice disorders showed LPR positive .The positive rate in the vocal fold leukoplakia group (71 .4% ) and Reinke's edema group (75 .0% ) were significantly higher than the control group (35 .7% ) .RSI and RFS of the patients with Reinke's edema were both significantly higher than the control group(P=0 .020 ,P=0 .009) .RSI of the patients with chronic pharyngolaryngitis were significantly higher than the control group (P=0 .019) .The acid reflux episodes ,acid reflux time which except in the supine position of the vocal fold leukoplakia group were significantly higher than the control group .The acid reflux episodes ,acid ex-posure and acid reflux time which all except in the supine position of the Reinke's edema group were significantly higher than the control group .Conclusion The correlations between Reinke's edema ,vocal fold leukoplakia and LPR were stronger .In these two groups ,the acid reflux episodes were higher and acid reflux times were longer .

Objective To explore the effect of dimethylformamide(DMF)on the histological structure and enzymes activity in the testis of mice.Methods The KM male mice were treated with DMF by gavage at the doses of 0,0.5,1 and 2 g/kg respectively, once a day,for 30 consecutive days.On day 31,the mice blood samples were collected through eyes and then the mice were killed. Two mice were randomly selected in each group and one testicle was sampled to do the pathological examination,the other one for enzyme activity determination,including succinic acid dehydrogenase(SDH),lactate dehydrogenase(LDH)and acid phosphatase (ACP).Results Compared with the control group,all treated groups showed a significant decrease in body weight(P

Objective To study the correlation between cognitive distress and tinnitus related handicaps.Methods One hundred and ninety-two primary tinnitus subjects ninety-nine males and ninety-three females were included in this study.The average age was 45±15.52 years old.The average durations of tinnitus for male and female were 25.67±37.71 months and 27.12±45.42 months, respectively.The patients were asked to fill the Mandarin tinnitus questionnaire (MTQ) and Mandarin (Chinese) tinnitus handicap inventory (THI-CM).The correlation between cognitive distress (CD) and tinnitus related handicap was studied.Results The average score of MTQ was 36.95±20.06.The average score of CD (Q17,18,23,41, and 42)was 2.61.The average score of question 17,18, 23,41, and 42 of MTQ was 2.81,2.63,2.59,2.40, and 2.41,respectively.The average score of THI-CM was 23.89±20.06.The correlation between CD and THI-CM was 0.64(P<0.01);for male and female were 0.63 and 0.66(P<0.01),respectively.The correlations between CD and THI-CM among young, middle and old age groups were 0.02,0.07 and 0.38(P>0.01),respectively.The correlations between CD and THI-CM among the nondisabled, mild, moderate and severe groups according to the scores of THI-CM were 0.30(P<0.01),0.29(P>0.01),-0.12(P>0.01), and 0.23(P>0.01),respectively.Conclusion No strong correlation was demonstrated between the CD and the THI-CM.The same results were shown for males and female.No correlation was demonstrated between ages and cognitive distress.Correlation coefficient of cognitive distress was increased with age.The tinnitus handicaps of patients might be vulnerable to cognitive distress with ageing.

Objective To investigate the changes of serum apolipoprotein A-I and its clinical significance to acute respiratory infection.Method Totally 44 patients with acute respiratory infection were divided into three groups according to various concentration of Serum apolipoprotein A-I.They were procaleitonin(PCT)<0.5 ng/ml group,0.5 ng/ml≤PCT<2 ng/ml group and PCT≥2 ng/ml group.We measured apolipoprotein A-I,C-reactive protein,procalcitonin and albumin within 24 hours after admission.Results With the increase of serumPCT,the production of ApoA-I and albumin were down-regulated,while CRP up-regulated.Conclusions Apolipoprotein A-I has a sound relationship with the acute respiratory infection.It can be used as one of the diagnostic criteria in severe infection patients who have disorders of lipometabolism.
