    Objective:To find the therapeutical effect of systemic inflammation in sleep disordered breathing(SDB) children after adnotonsillectomy. Methods:Polysomnography monitoring was performed in 65 snoring children all night and Conners concise questionnaire was applied to assess children′s behavior symptoms The change of serum C-reactive protein levels and improvement in abnormal behavior were compared in obstructive sleep apnea-hypopnea syndrome(OSAHS) childrenand primary snoring children before and 1 year after adnotonsillectomy. Results:The Conner′s concise  symptom questionnaire behavior score and serum C-reactiveprotein content of children with OSAHS were significantly higher than those of primary snoring children and healthy control children; and the two above indicators were also significantly higher in primary snoring children than in healthy control children. After adnotonsillectomy the score in Conners concise symptom questionnaire of OSAHS children was decreased form 14.2±3.8 to 6.7±3.1(P<0.05), and the serum C-reactive protein was decreased from (4.25±1.78)mg/L to(3.23±1.45)mg/L(P<0.05). The score of abnormal behavior in the primary snoring group was decreased from 9.4±4.1 to 5.1±2.8(P<0.05); the serumCreactive protein concentration fell from (2.77±1.80)mg/L to (1.76±0.81)mg/L(P<0.05). Conclusion:OSAHS and primary snoring children are  frequently associated with increases of CRP levels and a lot of behavior disorder problems,and those indicators and symptoms can become reversible after treatment by adnotonsillectomy.

    Objective To investigate the value of CT in the diagnosis of schwannomas of the  cervical sympathetic nerve (SSN) corrleated with surgical findings. Method Sixteen consecutive patients with schwannomas of the cervicalsympathetic nerve, proven by surgery and pathology,  were referred to computed tomography axialscanning. The CT findings for the location of masses, size, margin, contrast enhancement, and the rules of displacement of the common carotid artery, internal carotid artery and internal jugular vein were evaluated. Also the locations, characteristics of the lesions and rules of displacement of the common carotid artery, internal carotid artery and internal jugular vein were described with surgical correlation. Results 10 SSNs were located at the level of the commoncarotid bifurcation with the common carotid artery abutting against and displacing the lateral periphery of the tumor, and 16 SSNs with the internal carotid artery abutting against and displacing the lateral periphery of the tumor.  In 14 SSNs with enhanced CT, the internal jugular vein also abutted against and displaced the lateral periphery of the tumor. All the anatomical positional relationships among the commoncarotid artery, internal carotid artery and internal jugular vein with the cervicalsympathetic nerve were proved by operation. Conclusion CT axial scan can  accurately reflect the anatomical positional relationships among the common carotid artery, internal carotid artery and internal jugular vein with the cervical sympathetic nerve.

    ObjectiveTo explore the curative effectof Shuxuetong Injection in treating acute lowtone sensorineural hearing loss(ALSHL) and the possible reasonfor ALSHL. Methods We performed detailed audiology tests and administered Shuxuetong Injection on 42 patients diagnosed as ALSHL, and the curative effects were observed. Results  Of 42 patients, 33 completely recovered their hearing(25 healed after one course of treatment, and 8 healed after two courses of treatment), and 9 patients partly recovered after two courses of treatment. The curative ratewas 78.57%, and effective rate was 100%. 3 patients who were cured suffered recurrences after 3 to 24 months and were retreated with Shuxuetong Injection. One of them was cured again while 2 partly recovered. One had a homolateral bombus and unsteadiness while walking, which disappeared after symptomatic treatments.Conclusions Based on the fact that all patients were in their middle or senile ages, and most had a drinking problem or emotional agitation before the onset, we estimate that the disease may be related to vascular factors and blood viscidity changes, and the satisfactory effect of Shuxuetong Injection also supports our estimation

    which is worthy of notice for therapists.

    Objective To investigate newborn hearing disorders and clinical feature by analyzing data of newborn hearing screening. Methods The screening had three phases and included 6?159 newborns from May 2006 to Jan. 2009 in ourhospital. In phaseⅠ, the staff of the delivery suit screened newborn by Distortion Product Otoacoustic Emissions (DPOAE) between the third day and the seventh day after birth, or before the time of discharge. In phase Ⅱ, those who failed in phaseⅠ had a hearing test by DPOAE after forty-two days. Newborns who failed the second test were referred to a specified hospital for phase Ⅲ.  Audiometrists tested their hearing by Diagnostic Otoacoustic Emission, Auditory Brainstem Response and 40Hz Auditory Event Related Potential. Results 5594 newborns  were tested in phaseⅠand 4?641 passed, with a passrate of 82.96%. 953 newborns needed a further test, but only 507 newborns were tested in phase Ⅱ, and 447passed , with a passrate of 88.17%. Thirteen newborns (6 males and 7 females) were diagnosed as having hearing disorders in phase Ⅲ. The prevalence of newborn hearing disorders was 2.53‰ in all newborns, 2.41‰ in males and 2.63‰ in females. The prevalence rate of males showed no significant difference compared with that of females (P>0.05). The prevalence of hearing disorders of newbornswhoexperienced treatments after birth in a neonatal intensive care unit (NICU) was12.35‰ (five cases), and that of those without the experience was 1.69‰ (eight cases), the former's prevalence increased significantly compared with that of the latter (P<0.05). Conclusion The prevalence of newborn hearing disorders between males and females has no significant difference. Newborns who have experience in NICU demonstrate a higher prevalence than those without the experience. Themethod of two phases hearing screening by DPOAE can increase the pass-rate of the hearing test.

    Objective To explore the effects of stimulus intensity on gap detection responses of onset neurons in inferior colliculus(IC) of guinea pigs.  Methods Gap stimuli were noise bursts, with levels from 10 to 80?dB SPL. A series of silent gaps including 0, 1, 2, 4, 8, 16, 48 and 96ms gap duration were embedded between the initial 100?ms white noise burst (NB1) and the final 50ms burst (NB2) in the stimuli. The minimal gap threshold (MGT), first spike latency (FSL) andNB2 recovery rate were also analyzed according to four intensity groups: minimum threshold (MT), MT+10dB SPL (MT+10), MT+20dB SPL(MT+20), and MT+30dB SPL(MT+30). ResultsThirtyfive onset units were collected from 96 recorded neurons. The average MGT was (22.91±4.36)ms, (9.00±2.69)ms, (4.00±0.49)ms and (11.33±3.11)ms in the groups of MT, MT+10, MT+20 and MT+30, respectively (P<0.01). However, this effect was not significant among the group of suprathreshold. The NB2recovery rate in 48ms gap duration was 0.44±0.15, 0.83±0.12, 0.88±0.07 and 0.61±0.10, respectively. The FSL in 0ms gap duration was (12.86±0.72)ms, (11.65±0.64)ms, (11.03±0.65)ms and (10.68±0.55)ms respectively in the four groups. ConclusionThe level of white noise gap stimuli has some effects on thegap response in the onset unit of inferior colliculus in guinea pigs.
