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 investigate the long-term effect of nasal airflow deprivation on nasal dimensions after total laryngectomy. METHOD: Thirty-two patients with total laryngectomy were enrolled in the study. Acoustic rhinometry was used to measure the minimum cross-sectional area (MCSA) and the volume of the nasal cavity after laryngectomy, compared with the normal control group. In addition, patients underwent endoscopic nasal examinations and answered questionnaires postoperatively, symptoms between the different levels to compare the results of acoustic rhinometry. RESULT: At both within 1-year and more than 1-year follow-ups, the mean MCSAs and the mean nasal volumes were significantly expanded than the control values (P < 0.05). The nasal MCSA, nasal cavity volume was no significant difference between more than one year and less than 1 year group (P > 0.05). The endoscopic examinations revealed only a deterioration in the appearance of the nasal mucosa over the long term. Survey showed that the postoperative patients had varying degrees of nasal obstruction flu, nose dry, hyposmia, etc. The nasal MCSA, nasal cavity volume was of the largest when moderate nasal obstruction flu,or severe dry nose or severe hyposmia. CONCLUSION The structure was atrophic nasal change, the nasal MCSA, nasal cavity volume were larger, the results of acoustic rhinometry was different among the varying degrees of symptoms after total laryngectomy.

OBJECTIVE: To establish reference values of acoustic rhinometry, rhinomanometry and rhinospirometer in healthy adults in Tianjin area, analyze the effects of age,sex and side on the value, investigate the correlation of the measure values, offer the diagnosis date for test nasal ventilation function in Tianjin area. METHOD: Four hundred and sixty-six healthy adults in Tianjin area were tested. A1 acoustic rhinometry was used to measure the minimum cross-sectional area (MCA), distance of the minimal cross-sectional area to the nostril (DCAN) and the nasal volume from 0-5 cm, 2-5 cm (V5, V2-5); At 150 Pa, 75 Pa and broms, NR6 Rhinomanometry was used to measure unilateral nasal inspiratory resistance (IR)and expiratory resistance (ER), bilateral nasal inspiratory and expiratory resistance (TIR and TER), and differences of the bilateral nasal resistance can be calculated; NV1 Rhinospirometer was used to measure unilateral inspiratory capacity (IC) and expiration capacity (EC), and the nasal partitioning ratio (NPR) can be calculated. Practical measure the distance of nostril to ahead of the inferior turbinate and compare with DCAN. Make the correlational analysis on different index of three exam. RESULT: Reference values of acoustic rhinometry: MCA was (0.45 +/- 0. 16) cm2 for male, (0.44 +/- 0.16) cm2 for female; V2-5 was (3.52 +/- 1.38) cm3 for male, (3.36 +/- 1.22) cm3 for female, V5 was (5.10 +/- 1.47) cm3 for male, (4.86 +/- 1.12) cm3 for female; DCAN have two distance, (2.22 +/- 0.398, 0.53 +/- 0.625) cm was for male, (2.10 +/- 0.37, 0.67 +/- 0.15) cm was for female. No significant gender, side and age differences were shown in MCA, V5, V2-5. Significant gender differences were shown in DCAN but no side and age differences. Reference values of rhinomanometry: Significant gender but no side and age differences were shown in IR, ER, TIR, TER. Reference values of rhinospirometer: IC was (2.06 +/- 1.10) L/20 s for male, (1.37 +/- 0.34) L/20 s for female, EC was (2.15 +/- 1.23) L/20 s for male (1.39 +/- 0.58) L/20 s for female. NPRi was 0.11 [0.05, 0.23],NPRe was 0.11 [0.05, 0.19]. Significant gender but no side and age differences were shown in IC and EC. No gender and age differences were shown in NPRi and NPRe. There was significant correlation found between MCA and IR/ER/IC/EC, IR and IC, ER and EC, Rlr and NPRi/ NPRe. CONCLUSION Acoustic rhinometry,rhinomanometry and rhinospirometer can be useful reference values to evaluate nasal ventilation function, more value will be found if use the three together.

Objective To explore the hemodynamic assessment after radical surgery in children with tetralogy of Fallot (TOF) by both echocardiography and Mostcare monitor. Methods Clinical data of 63 children with TOF who underwent radical surgery in our hospital from February 2016 to June 2018 were retrospectively analyzed, including 34 males and 29 females, aged 6-24 (9.82±5.77) months. There were 19 patients undergoing transannular patch reconstruction of the right ventricular outflow tract (a transannular patch group) while 44 patients retained the pulmonary valve annulus (a non-transannular patch group) . The echocardiography and Mostcare monitor parameters were recorded and brain natriuretic peptide was tested at the time points of 0, 8, 12, 24 and 48 hours after operation (T 0, T 1, T 2, T 4) to analyze their correlations and the change trend at different time points after radical surgery. Results The left ventricular ejection fraction at T 1 (43.49%±3.82%) was lower than that at T 0 (48.29%±4.55%), T 2 (45.83%±3.69%), T 3 (53.76%±4.43%) and T 4 (60.54%±3.23%, P<0.05). The cardiac index at T 1 (1.85±0.35 L·min−1·m−2) was lower than that at T 0 (2.11±0.38 L·min−1·m−2), T 2 (2.07±0.36 L·min−1·m−2), T 3 (2.42±0.37 L·min−1·m−2) and T 4 (2.82±0.42 L·min−1·m−2, P<0.05). The cardiac circulation efficiency at T1 (0.19±0.05) was lower than that at T 0 (0.22±0.06), T 2 (0.22±0.05), T 3 (0.28±0.06) and T 4 (0.34±0.06, P<0.05). The right ventricular two-chambers view fraction area change at T 1 (23.17%±3.11%) was lower than that at T 0 (25.81%±3.74%), T 2 (25.38%±3.43%), T 3 (30.60%±4.50%) and T 4 (36.94%±5.85%, P<0.05). The pulse pressure variability was the highest at T 0 (18.76%±3.58%), followed by T 1 (14.81%±3.32%), T 2 (12.44%±2.94%), T 3 (10.39%±2.96%) and T 4 (9.18%±1.92%, P<0.05). The blood brain natriuretic peptide was higher at T 1 (846.67±362.95 pg/ml) than that at T 0 (42.60±18.06 pg/ml), T 2 (730.95±351.09 pg/ml), T 3 (510.98±290.39 pg/ml) and T 4 (364.41±243.56 pg/ml, P<0.05). There was no significant difference in left ventricular ejection fraction, cardiac circulation efficiency and heart index between the two groups (P>0.05). The right ventricular two-chambers view fraction area change of the transannular patch group was significantly lower than that of the nontransannular patch group at each time point (P<0.05). The blood brain natriuretic peptide and pulse pressure variability of the transannular patch group were significantly higher than those of the non-transannular patch group (P<0.05). Left ventricular ejection fraction was positively correlated with cardiac index (r=0.637, P=0.001) and cardiac circulation efficiency (r=0.462, P=0.001) while was significantly negatively correlated with blood brain natriuretic peptide (r=–0.419, P=0.001). Conclusion Both methods can accurately reflect the state of cardiac function. Mostcare monitor has a good consistency with echocardiography. Using transannular patch to recontribute right ventricular outflow tract in operation has more influence on right ventricular systolic function. The Mostcare monitor can guide the hemodynamic management after surgery in real time, continuously and accurately.
