Objective To investigate the effects of somatostatin (SST) on levels of IL-6,IL-8 and TNF-αduring CPB in pigs. Methods Twenty four healthy pigs were randomly divided into control group (SS00) and 3 experimental groups, SS05, SS10 and SS20. All pigs were performed by CPB for cardiac arrest in 45 min. the levels of IL-6, IL-10 and TNF-αwere tested and compared. Results The TNF-α, IL-6 and IL-10 levels were higher than T0 among all groups after CPB(P<0.05);The levels of TNF-αand IL-6 after CPB in SS10, SS20 groups were lower than SS00 group(P<0.05), and the IL-10 level was higher(P<0.05). Conclusion Infusing with a certain dose of SST before CPB could down-regulate acute inflammatory response;SST has no impact on the operative safety.

Objective: To analyze the role of frequency complemcntarities of vestibular tests including caloric test (CT),head shaking test(HST),and vibration test(VT) in the evaluation of vestibular function. Methods: Five hundreds and eightyfour patients with unilateral peripheral lesions were tested with CT, HST and VT in order to compare the frequency characteristic of abnormal vestibular function. Results: Of the 584 patients, 189 (32.36%), 283 (48.46%) and 368 (63.01%)cases showed vibration-induced nystagmus (VIN), head shaking nystagnms (HSN) and abnormal unilateral weakness (UW)respectively. There were 22 isolated VIN, 52 HSN and 145 cases of abnormal UW respectively. One hundred and fifty-nine (27.23%) cases had combination damage of two frequency bands, 101 (17.29%) had vestibular damage at all frequency bands,479 (82.02%) had abnormal results in any of the three tests, and 105 (17.98%) had no abnormality in all those three tests.Through consistency test, CT and HST (Kappa=0.106, P< 0.05), CT and VT(Kappa=0.068, P< 0.05), VT and HST (Kappa=0.321, P<0.05) showed low consistency among them. VIN and HSN were more hkely to be evoked with the increasing of the UW (X'2VIN=22.686,X2HSN=23.023, P< 0.05). Conclusion: The vestibular damage in the patients with vertigo could reflect at isolated low, middle, high frequency or multi frequency bands. Thus, CT, HST and VT all make significant contributions to multiple-frequency analysis of vestibular function and show a well complementarities. So they can be used in evaluating the overall function of the vestibular and indicating a serious vestibular lesion if the damage affected multi frequency bands.

OBJECTIVE To study the electrophysiological character of the Auditory Brainstem Response to Speech Sounds (s-ABR) in healthy adults. METHODS We assessed the auditory brainstem response to a synthesized stop-consonant speech syllable /da/ in 40 native-Chinese speech adults (20 female). Timing components of the response were compared between males and females to determine the relationship between inducing rate ,latency of waves and sex and age of participants. RESULTS The latency of wave V and A was shorter in females was that of males (Vt(38)=-3.601, P =0.001, At(38)=-2.829, P=0.007).The other peaks latency except V、A can see difference between gender but do not have statistics differences (P>0.05); The latency has no statistical difference in different age (P>0.05); The amplitude has no statistical difference in different gender and age (P>0.05). CONCLUSION The waves of s-ABR has good stability for studying mechanism of auditory speech processing tools.

Objective:To analyze the result of smooth pursuit test(SPT) in unilateral vestibular peripheral vertigo and investigate its influencing factors.Method:Smooth pursuit test (SPT) and spontaneous nystagmus (SN)were examined in one hundred and eighty-five patients with unilateral peripheral vertigo(case group) and 51 normal persons(control group) by Video-Nystagmography (Synapsys, France), and the gain of SPT and SN were selected as the observation parameters in order to analyze the waveform and gain of SPT and the relativity between SN and the gain of SPT.Result:Of the 185 patients, 105(56.8%),72(38.9%) and 8(4.3%) cases producedⅠ,Ⅱ and Ⅲ waveforms respectively. Of these patients, 58(31.4%) demonstrated SN and none had Ⅳ waveform. While of 51 normal persons, 38(74.5%), 13(25.5%) persons producedⅠand Ⅱwaveforms repectively and there were no Ⅲ, Ⅳ waveforms or SN. There was statistical significance between the stong and weak gain of SPT in these two groups. Weak gain was significantly different between two groups. The stong and weak gain of SPT in case group were 0.86±0.06,0.80±0.06; 0.78±0.09, 0.65±0.1; 0.68±0.13, 0.45±0.12. The relativity between SN and the gain of SPT was positive when they had same direction(r_s=-0.63,P<0.05)and negative when opposite (r_s=0.34,P<0.05).Conclusion:Ⅰ,Ⅱ,Ⅲ three waveforms of SPT could appear in unilateral vestibular peripheral vertigo and the corresponding gains are gradually decreasing.SN is the influencing factor of SPT.

Objective To evaluate the diagnostic accuracy of CMS50F for screening in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Sixty-four volunteers with suspected OSAHS underwent simultaneous noc?turnal polysomnography (PSG), micromovement sensitive mattress sleep monitoring system(MSMSMS)and CMS50F. The ap?nea-hypopnea index (AHI) detected by PSG and MSMSMS was used as the diagnostic standard for OSAHS. The reliability of CMS50F for monitoring sleep was assessed. Results There was no statistic difference in CMS50F-ODI3 and PSG-AHI be?tween normal, mild and moderate OSAHS groups(P>0.05). The CMS50F-ODI3 was smaller than the PSG-AHI in severe OSAHS patients(P < 0.05). There was a positive correlation between CMS50F-ODI3 and PSG-AHI(r=0.855, P < 0.05). PSG-AHI≥5 events per hour was used as the threshold value to diagnose OSAHS, the sensitivity and specificity of CMS50F were 94.5%and 88.9%. There were no significant differences in CMS50F-ODI3 and MSMSMS-AHI between normal, mild and moderate OSAHS patients(P>0.05). The value of CMS50F-ODI3 was smaller than MSMSMS-AHI in severe OSAHS patients (P < 0.05). There was also a significant correlation between CMS50F- ODI3 and MSMSMS-AHI (r=0.867,P <0.05). MSMSMS-AHI≥5 events per hour was used as the threshold value to diagnose OSAHS, the sensitivity and specificity of CMS50F were 94.5%and 88.9%. Conclusion CMS50F can be used as a portable and reliable device for screening of pa?tients suspected OSAHS.

OBJECTIVE:
To investigate the screening value and the reliability of the monothermal caloric tests (MCT) in evaluating vestibular function.
METHOD:
One thousand and four hundred and six vertigo patients were divided into two groups. Seven hundred and five cases were stimulated by different temperature air from cold to warm. The caloric test sequence of other 701 cases was opposite. The first stimulated cold or warm air test was regarded as monothermal cold caloric test (MCCT) or monothermal warm caloric test (MWCT). The unilateral weakness (UW) and directional preponderance (DP) of the bithermal caloric tests (BCT) and the UW of the MCT were calculated. By defining the BCT results as the standard, the sensitivity, specificity, Youden's index and kappa were calculated.
RESULT:
Four hundred and twenty-eight showed abnormal BCT and MCCT. One hundred and forty-five showed normal BCT and MCCT. 85, 47 showed isolated abnormal BCT and abnormal MCCT respectively. The sensitivity of the MCCT was 83.4%, specificity was 75.5%, Youden's index was 0.589 and kappa was 0.555 (P<0.01). Four hundred and twenty-nine showed abnormal BCT and MWCT, 130 showed normal BCT and MWCT. 82, 60 showed isolated abnormal BCT and abnormal MWCT respectively. The sensitivity of the MWCT was 84.0%, specificity was 68.4%, Youden's index was 0.524 and kappa was 0.505 ( P<0.01). The sensitivity of the MCCT and MWCT were 86.9% and 86.9% respectively when cases accompanied by spontaneous nystagmus (SN) were excluded. The sensitivity of the MCCT and MWCT were 89.3% and 88.1% respectively when cases with abnormal DP were excluded.
CONCLUSION
The high false-positive and false-negative rate of the MCT limit the usefulness as a screening test due to the influence of DP and SN.
