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.

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.

ObjectiveTo evaluate the clinical efficacy and safety of astragalus injection on the immune function in patients with senile sepsis.Methods Sixty patients with old age sepsis in Critical Care Medicine Department of Guangdong Provincial Traditional Chinese Medicine Hospital were enrolled and randomly assigned into control and treatment groups according to the table of random numbers, 30 cases in each group. According to 2012 sepsis guidelines for treatment, including antibacterial drug, mechanical ventilation, visceral function support, etc., the therapy was given to the control group; besides the treatment in the control group, intravenous drip of 60 mL astragalus injection(10 mL per ampoule) in 250 mL 0.9% normal saline was additionally given in the treatment group, once a day for 7 days. Before and after treatment, the immunological indexes, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment(SOFA) score, duration of mechanical ventilation and time of stay in intensive care unit(ICU), 28-day mortality and adverse drug reactions were compared between the two groups.Results Before treatment, there were no statistically significant differences in CD3+, CD3+CD4+, CD3+CD8+ and T helper cells /T suppressor cells(Th/Ts)levels between the two groups(allP>0.05), while CD3-NK+ of the control group was significantly higher than that in the treatment group〔(10.47±6.22)% vs. (6.26±4.13)%,P<0.05〕. After treatment in treatment group, CD3+, CD3+CD4+ and CD3-NK+ were increased, CD3+CD8+,Th/Ts were decreased compared with those before treatment; in the control group after treatment, CD3+,CD3+CD8+ and CD3-NK+ were decreased and CD3+CD4+ and Th/Ts increased compared with those before treatment. In the comparisons between the treatment group and control group after treatment, the differences in CD3+, CD3+CD4+ and CD3+CD8+ had statistical significance〔CD3+:(30.30±17.17)% vs.(41.91±22.29)%, CD3+CD4+:(31.54±13.24)% vs.(40.08±15.28)%, CD3+CD8+:(14.25±8.10)% vs.(9.52±9.33)%,allP<0.05〕; while the differences in Th/Ts and CD3-NK+ had no statistical significance(bothP>0.05). After treatment in the treatment group, IgG was increased compared with that in the control group〔IgG(g/L): 13.07±5.43 vs. 10.10±3.96,P<
0.05〕. The differences in IgA, IgM, complement(C3,C4) and total serum complement activity(CH50) in the comparisons between the two groups had no statistical significance after treatment(allP>0.05). The differences in APACHEⅡ score(13.83±6.18 vs. 15.90±7.48), SOFA score(7.38±4.66 vs. 6.89±4.19), time of stay in ICU(day: 11.63±5.13 vs. 13.62±8.08), invasive ventilation time(hour: 155.44±119.68 vs. 224.08±174.15) and noninvasive ventilation time(hour: 55.55±42.24 vs. 98.57±43.17) had no statistical significance in comparisons between the treatment group and control group after treatment(allP>0.05). The difference in 28-day mortality had no statistical significance in comparison between the treatment group and control group〔16.7%(5/30) vs. 20.0%(6/30),P>0.05〕. In 60 cases, there were 2 patients with adverse drug reaction, one diarrhea and another little rashes, the rest of the patients did not appear any drug side effect.ConclusionAstragalus injection combined with conventional western medicine therapy possibly has certain effect on adjustment of disturbance of immunologic functions in old patients with sepsis, and its therapeutic safety is well.

Objective To observe hemodynamic characteristics and the correlation with syndrome types of traditional Chinese medicine (TCM) in patients with septic shock, so as to direct the treatment based on syndrome differentiation. Methods A prospective observation was conducted. Sixty-eight patients with septic shock admitted to the Department of Critical Care Medicine of Dade Road General Hospital of Guangdong Hospital of TCM from January 2013 to July 2015 were enrolled. Pulse indicating continuous cardiac output (PiCCO) was used to monitor the hemodynamic changes, including heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), cardiac index (CI), global end diastolic volume index (GEDVI), extravascular lung water index (EVLWI), maximum rate of the increase in pressure (dPmax) and systemic vascular resistance index (SVRI), for assessment of hemodynamics. According to the CI, the patients were divided into two groups , i.e. high CI group (CI ≥ 50.0 mL·s-1·m-2, n = 34) and low CI group (CI < 50.0 mL·s-1·m-2, n = 34), and the clinical and hemodynamic characteristics of two groups were investigated. The TCM differentiation was conducted with four syndromes and four methods, and the hemodynamic characteristics of different syndrome types were investigated, the correlation between the TCM syndrome factors and hemodynamic parameters was analyzed. The patients were divided into survival group and death group, and clinical parameters and hemodynamic characteristics were compared between two groups. Results The acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and blood glucose of low CI group were higher than those of high CI group [APACHEⅡ score: 24.4±7.2 vs. 19.8±7.4, t = -2.279, P = 0.023; blood glucose (mmol/L): 9.7 (7.7, 14.6) vs. 6.7 (5.6, 10.0), Z = -2.257, P = 0.024], CI and GEDVI were lowered [CI (mL·s-1·m-2): 36.7±8.3 vs. 68.4±16.7, t = 10.285, P = 0.000; GEDVI (mL/m2): 689.0 (566.0, 883.8) vs. 838.5 (692.8, 1 247.3), Z = -2.711, P = 0.007], while SVRI was increased [kPa·s·L-1·m-2: 248.7 (202.1, 324.5) vs. 143.4 (102.7, 171.4), Z = -5.336, P = 0.000]. Accompanied symptoms were found to occur more commonly in septic shock patients, and the most common syndrome elements were Qi deficiency syndrome (n = 45), blood stasis syndrome (n = 40), heat-toxin syndrome (n = 37), Fushi syndrome (n = 24) and Yin deficiency syndrome (n = 10), respectively. There was no significant difference in hemodynamic parameters among patients with five types of syndrome (all P > 0.05). However, only the CI of those with Qi deficiency syndrome was significantly lower than that of heat-toxin syndrome (mL·s-1·m-2: 48.3±18.3 vs. 53.3±21.7, P < 0.05). While the results after removing the effect of accompanied symptoms showed that CI of Qi deficiency syndrome was significantly lower than that of non-Qi deficiency syndrome (mL·s-1·m-2: 48.3±18.3 vs. 61.7±21.7, t = -2.783, P = 0.007), CI of heat-toxin syndrome was significantly higher than that of non-heat-toxin syndrome (mL·s-1·m-2: 58.3±21.7 vs. 48.3±16.7, t = 2.133, P = 0.037), EVLWI of blood stasis syndrome was significantly lower than that of non-blood stasis syndrome [mL/kg: 10.0 (7.0, 15.1) vs. 14.9 (8.5, 26.8), Z = -2.075, P = 0.038]. Compared with survival group (n = 38), APACHEⅡ score in death group (n = 30) was increased (25.8±8.4 vs. 19.1±5.4, t = -3.940, P = 0.000), the proportion of continuous renal replacement therapy (CRRT) was increased [60.0% (18/30) vs. 31.6% (12/38), χ2 = 5.493, P = 0.019], HR was increased (bpm: 118.5±20.5 vs. 98.1±19.9, t = -4.157, P = 0.000), and the proportion of Qi deficiency syndrome was increased [86.7% (26/30) vs. 50.0% (19/38), χ2 = 10.070, P = 0.002]. Conclusions Patients with sepsis shock may be divided into high-output and low-resistance & low-output and high-resistance groups according to hemodynamics, with respective hemodynamic characteristics. Hemodynamic performance differed among different syndrome types, and there was a certain relationship. Hemodynamic monitoring with PiCCO was a useful supplement of TCM, which was good for the evidence-based medicine.
