The giant magnetoimpedance(GMI)effect and effective permeability ratio in a QFR/Cu/QFR sandwiched structure are studied,where QFR stands for the as-quenched FeNiCrSiB amorphous *** GMI effects are obtained in the QFR/Cu/QFR sandwiched structure without *** maximum values of the longitudinal and transverse GMI ratios at 0.5 MHz are 282%and 408%,***,the maximum effective permeability ratios at 0.5 MHz are 326%and 1013%in longitudinal and transverse field,*** large GMI values are attributed to the high effective permeability of the sample due to the closed alternating current(ac)magnetic flux path in the sandwiched structure,and large permeability variation induced by the magnetic field.

Background Medical ozone therapy system was reported to have certain effects on the treatment of severe hepatitis, but its mechanism is not very clear. One of the causes of death of severe hepatitis is complication of renal damage or hepatorenal syndrome. The present study aimed to observe effects of medical ozone therapy system on plasma renin activity （PRA）, angiotensin II （All）, aldosterone （ALD）, renal blood flow and renal function of patients with chronic severe hepatitis and explore mechanisms of medical ozone therapy in the treatment of severe hepatitis. Methods Eighty-five cases with chronic severe hepatitis were randomly divided into ozone therapy group （43 cases） and control group （42 cases）. The patients in the ozone therapy group were treated with basic treatments plus ozone therapy system. Basic autohemotherapy was used. One hundred milliliter venous blood was drawn from each patient, and was mixed with 100 ml （35 pg/ml） medical ozone and then was returned the blood to the patient intravenously, once every other day for 20 days. Only the basic treatments were given to the control group. PRA, All, ALD, renal blood flow and damage to renal function of the two groups before treatment and 20 days after treatment were compared. Survival rates were also compared. Results Twenty days after the treatment, in ozone therapy group, PRA was （1.31±0.12） ng.m^-1.h^1, All （111.25±17.35） pg/ml, ALD （251.31±22.60） pg/ml, which decreased significantly compared with those before treatment （PRA （2.23±0.13） ***^-1.h^-1, All （155.18±19.13） pg/ml, ALD （405.31±29.88） pg/ml, t=4.67-14.23, P 〈0.01 ）, also lower than those of control group 20 days after the treatment （PRA （2.02±0.11） ***^-1.h^-1, All （162.21±15.32） pg/ml, ALD （401.20±35.02） pg/ml, t=4.97-15.61, P 〈0.01）; renal blood flow was （175.15±28.20） ml/min, which increased compared with that before the treatment （（125.68±21.25） ml/min） and was higher than that of control group 20 days after the treatment （（128.59±23.15

该试验旨在筛选具有高产蛋白酶能力的益生芽孢杆菌,扩大微生态制剂候选菌株资源。以边鸡直肠内容物为分离来源,经脱脂奶粉平板初筛获得16株产蛋白酶菌株,液体发酵复筛后,选取1株蛋白酶活力高达119.7 U/mL的芽孢杆菌FRE76进行后续研究。通过16S rRNA基因测序与进化树分析,并结合形态学与生理生化鉴定,判定该菌株为枯草芽孢杆菌。病原菌抑制试验表明,该菌对大肠杆菌和金黄色葡萄球菌均有明显的抑制作用。耐酸和耐胆盐检测发现,在pH值3.0和4.0时该菌株存活率均为50%以上,在胆盐浓度为0.1%和0.3%时菌株存活率均能达到60%以上。该试验筛选获得的枯草芽孢杆菌FRE76,具有优良的蛋白酶生产性能、较好的致病菌抑制能力和较强的抗逆性,是一株潜在的益生菌菌株。

目的探讨青少年1型糖尿病(T1DM)患儿的授权能力及其影响因素。方法采用一般资料调查表、糖尿病授权量表(DES-SF)中文简化版、慢性病儿童应对方式(CODI)量表和父母教养方式(EMBU)量表对131例青少年T1DM患儿进行调查。比较不同特征患儿的授权能力。分析患儿授权能力与应对方式、父母教养方式的相关性,以及授权能力的影响因素。结果患儿的DES-SF总分为(4.09±0.83)分,授权能力水平低、中等及高的患儿比例分别为13.74%、72.52%和13.74%。不同病程、是否独立注射胰岛素、是否独立测血糖和不同父母婚姻状态的患儿DES-SF总分差异有统计学意义(P<0.05)。DES-SF总分与自我安慰、接受及远离应对方式均分和自我评价均分,以及父母情感温暖、理解因子均分呈正相关(P<0.05),与父亲惩罚、严厉及父母拒绝否认因子均分呈负相关(P<0.05)。多元线性回归分析结果显示,病程为6~12个月可降低患儿授权能力,不独立注射胰岛素、接受应对方式均分增加、自我评价均分增加可提高患儿授权能力(P<0.05)。结论青少年T1DM患儿授权能力较好,接受应对方式和正向的自我评价可以提高患儿授权能力,病程为6~12个月可降低患儿授权能力,但尚不能认为独立注射胰岛素可以提高患儿的授权能力。
