Journal of Audiology and Speech Pathology 2015;(1):29-31
Objective To find out the influence of different suffix vowel(abbreviation:SV) on the duration of/s/(a voiceless fricative) with acoustic detection method. Methods Two men and two women who were fluent in Mandarin Chinese were recruited in this study. The words included /s/and the suffix vowel /a/,/u/or/i/.The CSL4150 software from Kay Co. was used to analyze the words. Then we compared the durations of/s/when the suffix vowel was /a/,/i/and/u/,respectively. The influence of difference suffix vowel on the duration was exam_ined, and gender effects were also studied on the duration. ResuIts As a voiceless fricative, when the suffix vowel was /a/,the duration for males was 200. 2, and 276. 8 ms for females, respectively. When the suffix vowel was /i/, the duration for males was 218. 2, and 326. 5 ms for females, respectively. When the suffix vowel was /u/,the dura_tion for males was 214. 5, and 302. 9 ms for females, respectively. ConcIusion When the suffix vowel is different, the duration of stop, resistance and in number is different, and also affected by gender.

Objective To investigate the association between vascular risk factors and the location of intracranial artery stenosis (anterior versus posterior).Methods Magnetic resonance angiography(MRA) were examined in 374 acute stroke patients.It was divided into two groups (anterior and posterior intracranial artery stenosis group).Analyzed possible risk factors.Results Univariate analysis showed there were differences between anterior and posterior intracranial artery stenosis in systolic blood pressure,history of smoking,drinking and stroke status,and national institutes of health stroke scale (NIHSS) score at discharge,short-term prognosis,serum creatinine,triglyceride,low density lipoprotein cholesterol (LDL-C) (P < 0.05).In multivariate logistic regression analysis,high blood sugar (OR =1.135,95% CI:1.003-1.284),history of stroke(OR =1.133,95% CI:1.007-1.276),good short-term prognosis (OR =5.987,95% CI:1.441-24.873) were preferentially related to anterior intracranial artery stenosis,whereas history of smoking (OR =0.003,95 % CI:0.000-0.376),high serum creatinine values (OR =0.509,95 % CI:0.328-0.790),high triglyceride values (OR =0.054,95% CI:0.004-0.645) and high LDL-C values (OR =0.096,95% CI:0.015-0.608) were preferentially related to posterior intracranial artery stenosis.Conclusion Vascular risk factors appeared to exert different effects of risk for anterior and posterior intracranial artery stenosis.

ObjectiveTo investigate the effects of Xuebijing injection on hemodynamics, cardiac function, and endothelial function in patients with severe sepsis in order to study the therapeutic effect of Xuebijing in the treatment of severe sepsis.Methods A prospective randomized controlled trial was conducted. Sixty-six severe sepsis patients admitted to the Department of Critical Care Medicine of Guangdong Hospital of Traditional Chinese Medicine from March 2013 to February 2014 were enrolled. The patients were divided into control group (n = 31) and Xuebijing group (n= 35). The patients in both groups were treated according to 2012 international guidelines for management of severe sepsis and septic shock, and the patients in Xuebijing group received Xuebijing injection of 50 mL (added with 100 mL of 0.9% sodium chloride injection) twice a day for 5 days, and those in control group received instead 150 mL of 0.9% sodium chloride injection for 5 days. The heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), and dosage of vasoactive drugs before and 1 day and 5 days after treatment were determined for hemodynamics assessment. Blood lactic acid (Lac), central venous oxygen saturation (ScvO2), and difference in arterial-venous blood carbon dioxide pressure (Pv-aCO2) were determined for microcirculation assessment. The left ventricular ejection fraction (LVEF), cardiac output (CO), left ventricular end diastolic diameter (LVEDD), the ratio of blood flow of mitral orifice between rapid filling period and atrial systole period (E/A), and B-type natriuretic peptide (BNP) were determined for cardiac function assessment. Vascular endothelial growth factor (VEGF) and soluble receptor (sFLT-1) were assessed for endothelial function assessment. The relationship among the indexes of the hemodynamics, microcirculation, cardiac function, and endothelial function was analyzed with Pearson related-analysis.Results After treatment, HR, MAP, CVP, Lac, ScvO2, and Pv-aCO2 were improved in both groups compared with those before treatment, and the dosage of norepinephrine (NE) was decreased in Xuebijing group. Compared with control group, MAP at 5 days after treatment in Xuebijing group was significantly increased [mmHg (1 mmHg =0.133 kPa): 74.9±10.7 vs. 70.2±6.6,P< 0.05], the dosage of NE was decreased [μg·kg-1·min-1: 0.01 (0.00, 0.22) vs. 0.10 (0.05, 0.80),P< 0.05], LVEF was significantly increased (0.617±0.125 vs. 0.533±0.129,P< 0.05), BNP was significantly decreased [ng/L: 117.3 (52.0, 443.0) vs. 277.2 (67.9, 2 370.2),P< 0.05], while VEGF showed no significant change (ng/L: 101.1±23.2 vs. 89.6±20.5,P> 0.05), and sFLT-1 was significantly decreased (ng/L:245.7±86.2 vs. 295.1±95.1,P< 0.05). It was shown by Pearson coefficient bivariate correlation analysis that sFLT-1 was negatively correlated with MAP and ScvO2 (r= -0.569,P= 0.000;r= -0.341,P= 0.008) 5 days after treatment, while it was positively associated with Lac and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score (r= 0.749,P= 0.000;r= 0.645,P= 0.000).Conclusions In patients with severe sepsis, there are hemodynamics disorders and effect in microcirculation perfusion. Xuebijing injection can improve hemodynamics and cardiac function in the patients with severe sepsis, and the mechanism may be related to the improvement of endothelial function.

Objective To investigate the effect of imaging parameters and postprocessing methods on the quality of MR imaging of short T2 components with 3D ultrashort TE (UTE) double echo pulse sequence. Methods 3D UTE double echo pulse sequence was performed on dry human femoral specimen and the tibial diaphyses, knee joints, and tendons of ankles of a group of healthy volunteers. To investigate the effect of different trajectory delays of the imaging system(-6, -3, -2, - 1,0, 1,2, 3 s), different flip angles(4°, 8°, 12°, 16°, 20°, 24°), different TEs (0. 08, 0. 16, 0. 24, 0. 35 ms)and different postprocessing methods(difference imaging of subtracted volume and non-volume UTE)on the 3D UTE MR imaging quality, the SNR and CNR were calculated and compared, and the artifacts of the images were analysed. Results The cortical bone, periosteum, tendon and meniscus showed high signal intensity on the images of UTE pulse sequence. The best SNR was acquired with 2 s trajectory delay. The best flip angle was 8° to 12° for the human UTE imaging in vivo. The highest CNR was obtained from the TE of 0. 08 ms. The longer the TE was, the more artifacts appeared. The SNR of difference imagewas improved when image subtraction was performed afer multiplanar reconstruction (MPR) of the primary double echo images.Conclusions The short T2 components show high signal intensity on the MRI of 3D UTE double echo pulse sequence. The imaging quality can be improved by shortening TE, using appropriate flip angle and performing subtraction for difference image after MPR of the primary double echo images.
