目的:为了确定超声心动图左室心功能指标在预测心脏排异方面是否有用.方法:对12例心脏移植接受者(年龄3～17岁)进行了52次超声检查及穿刺活检,并将结果与12名正常少儿(年龄2～17岁)进行对照.组织活检被分为无排异(n=23),轻度排异细胞渗透(n=13),中度排异肌细胞坏死((n=16).通过M型及二维超声心动图对左室径线(LVD),短轴缩短率(FS),左室质量(LVM),射血分数(EF)进行了测定.结果:通过对二尖瓣多普勒采用包罗线方法得到如下数据:等容舒张时间(IVR),E峰和A峰速度,充盈分数.与正常人对照无排异的移植受者心率较快,等容舒张时间较长,头1/3面积分数减少.而EF、LVM、E、A峰速度均相同.中度排异与无排异的患者比较,EF和E峰速度均减低了.结论:从轻度到中度排异,各指标无进一步变化.这些指标对于心脏排异反应都不具有特异性.

BACKGROUND Israel has a high rate of jewish immigration and a high prevalence of inflammatory bowel disease(IBD).AIM To compare IBD prevalence in first-generation immigrants vs Israel-born *** Patients with a diagnosis of IBD as of june 2020 were included from the validated epi-IIRN(Israeli IBD Research Nucleus)cohort that includes 98%of the Israeli *** stratified the immigration cohort by IBD risk according to country of origin,time period of immigration,and age group as of june *** A total of 33544 patients were ascertained,of whom 18524(55%)had Crohn’s disease(CD)and 15020(45%)had ulcerative colitis(UC);28394(85%)were Israel-born and 5150(15%)were *** was more prevalent in immigrants(2717;53%)than in non-immigrants(12303,43%,Pjusting for age,longer duration in Israel was associated with a higher point prevalence rate in june 2020(high-risk origin:Immigration<1990:645.9/100000,≥1990:613.2/100000,P=0.043;intermediate/low-risk origin:<1990:540.5/100000,≥1990:192.0/100000,P<0.001).The prevalence was higher in patients immigrating from countries with high risk for IBD(561.4/100000)than those originating from intermediate-/low-risk countries(514.3/100000;P<0.001);non-immigrant prevalence was 528.9/*** Lending support to the environmental effect on IBD etiology,we found that among immigrants to Israel,the prevalence of IBD increased with longer time since immigration,and was related to the risk of IBD in the country of *** UC rate was higher than that of CD only in those immigrating in earlier time periods.
