Objective To study different test positions on vestibular evoked myogenic potentials (VEMPs) in youth ,and to find a suitable position and provide a guidance for clinical practice .Methods Thirty normal young vol-unteers were tested by vestibular evoked myogenic potentials ,using three different positions :supine with the head held straight up(SHU),supine with the head held up and turned away from the test ear(SHT),sitting with the head turned away from the test(SIT) ,the derivation rate ,latency and amplitude were analyzed .Results The deri-vation rate of SHU ,SHT and SIT were 100% ,100% and 63 .3% ,respectively .The derivation rate ,p13 ,n23 la-tency and p13 n23 inter-latency between SHU and SIT ,and between SHT and SIT had statistical differences (P<0 .05) .No statistical significant differences were found in derivation rate ,p13 ,n23 latency and p13n23 inter-latency between SHU and SHT (P>0 .05) .The amplitude was significantly different among the three positions (P<0 .05) . No statistical significant difference were found in derivation rate ,p13 ,n23 latency ,p13 n23 inter -latency and am-plitude between men and women of the three positions (P> 0 .05) .Conclusion The derivation rate of SHT was 100% with maximum amplitude .SHT is the most recommended position for clinical test in youth .The derivation rate of SHU was 100% ,and no statistical significant difference were found in p13 ,n23 latency and p13n23 inter-la-tency between SHU and SHT (P>0 .05) .SHU can be used in clinical test .SIT is not recommended for using in clinical test .Gender does not affect VEM Ps test .

Objective To explore the status of depression in patients with advanced schistosomiasis and its influencing fac-tors,so as to provide the evidence for improving psychological interventions. Methods A total of 206 patients with advanced schistosomiasis were investigated with the self-designed general information questionnaire,the Self-Rating Depression Scale,and WHOQOL-BREF Form. Results Among the 206 cases,the incidence of depression was 69.4%,and depression was negatively related to the quality of life(P = 0.000). The multiple logistic regression analysis showed that the times of hospitalization(β=0.442,P=0.007)was a risk factor for depression,while the high education levels(β=-0.583,P=0.011)and the history of por-tal hypertension operation(β=-0.917,P=0.000)were the protective factors. Conclusion The incidence of depression in ad-vanced schistosomiasis patients is high,and it is influenced by various factors. Therefore,we should take corresponding interven-tions to reduce its occurrence.

An ultrasensitive electrochemical immunosensor modified with graphene and dienestrol(DE)was developed for the detection of dienestrol through indirect competition with K3Fe(CN)6 acting as the redox probes. The results revealed that under optimized conditions a calibration for DE was obtained with a linear range of 500-5 000 ng/mL and the detection limit was up to 0. 2 ng/mL, showing that the proposed electrochemical immunosensor had excellent sensitivity and wide detection range. The immunosensor was examined in real samples for the analysis of DE. A good recovery in the range of 83. 8%-97. 7% was obtained in pork samples.

Objective To investigate the application of fiberoscope on upper airway compliance in OSAHS patients with MSMSMS. Methods From May 2014 to December 2015,93 patients with OSAHS in Jinhua Central Hospital were detected by MSMSMS[including 32 mild cases (MI),31 moderate cases (MO),and 30 severe cases (SE)] underwent electronic nasopharyngeal examination combined with the Muller test. The course of 93 OSAHS patients were recorded,including body mass index (BMI),sleep apnea index (AHI),mean oxygen saturation. The degree of collapse in the patients' soft palate area,tongue,epiglottis after area were calculated by the software. The results were analyzed by SPSS15. 0 statistical software. Results The disease courses between the mild group and moderate group [(4. 93 ± 2. 91)years,(8. 91 ± 4. 87)years],as well as between the moderate group and severe group [(4. 93 ± 2. 91)years,(9. 27 ± 4. 75) years],had statistically significant differences (t = - 3. 97,P = 0. 001;t =- 4. 33,P < 0. 001). The pairwise intergroup comparison of AHI among the three groups[(7. 75 ± 2. 49) times, (23. 24 ± 3. 74)times,(53. 27 ± 13. 59)times] showed statistically significant differences(t = 15. 49,P = 0. 000;t =- 45. 52,P = 0. 000;t = - 30. 02,P = 0. 000). The differences of MSaO2 between the mild group and severe group [(94. 25 ± 1. 11)％ vs. (94. 45 ± 0. 72)％ ],as well as between the moderate group and severe group[(94. 45 ± 0. 721)％ vs. (91. 40 ± 3. 17)％ ] had statistically significant differences ( t = 2. 85,P = 0. 000;t = 3. 05,P =0. 000). In the SE,there was a positive correlation with mean oxygen saturation (r = 0. 45,P = 0. 007). The collapse of soft palate area among the three groups had statistically significant differences (t = 3. 74,P = 0. 005;t = - 8. 39, P = 0. 000;t = - 4. 65,P = 0. 001). The collapse of posterior tongue area between the moderate group and mild group [(72. 65 ± 1. 56)％ vs. (66. 69 ± 8. 64)％ ],the mild group and severe group[(66. 69 ± 8. 64)％ vs. (74. 33 ± 10. 96)％ ] had statistically significant differences (t = 5. 96,P = 0. 008;t = - 7. 65,P = 0. 001). There was no statistically significant difference between the moderate group and severe group in the collapse of posterior tongue area (P > 0. 05). There were statistically significant differences between the mild group and moderate group[(63. 84 ± 8. 81)％ vs. (75. 06 ± 5. 07)％ ],the mild group and severe group[(63. 84 ± 8. 81)％ vs. (76. 40 ± 7. 94)]in the collapse of epiglottic area (t = 11. 22,P = 0. 000;t = - 12. 56,P = 0. 000). There was no statistically significant difference between the moderate group and severe group in the collapse of epiglottic area(P > 0. 05). Conclusion Fiberoscope combined with Müller test can respond better upper airway compliance in OSAHS patients with MSMSMS. It is worth to promote in clinic.
