Objective To evaluate the vulnerability of carotid arteriosclerosis plaque by ultrasound real-time tissue elastography in patients with SSS-TOAST1 style cerebral infarction, and discussing the value of the technique in assessment of the clinical course after cerebral infarction. Methods There were 113 patients of SSS-TOAST1 style cerebral infarction who had carotid arteriosclerosis plaque and 48 patients of contrast group who had carotid arteriosclerosis plaque selected by ultrasound in Department of Ultrasound, Beijing Tiantan Hospital, Capital University of Medical Sciences. The results between two groups were compared. The cerebral infarction group was divided into two sub-groups according to the clinical course of patients after cerebral infarction, and the difference between them was compared. Results The size had no significant difference between cerebral infarction group and contrast group as well as between aggravated group and non-aggravated group (t=15.61, 10.77, 4.52, P<0.05). The real-time tissue elastography of carotid arteriosclerosis plaques were red-green in most patients of cerebral infarction group. The real-time tissue elastography of carotid arteriosclerosis plaques were green-blue in most patients of in control group. The value of elasticity of plaque, vessel wall and stiffness of carotid arteriosclerosis plaque between cerebral infarction group and control group had significant differences (t=15.61, 10.77, 4.52, P<0.05). The value of real-time tissue elastography between aggravated group and non-aggravated group had significant difference (t=6.39, 2.30, 3.80, P<0.05). Conclusion Real-time tissue elastography could evaluate the stiffness of carotid arteriosclerosis plaque, which was related with the vulnerability of carotid arteriosclerosis plaque. The values of elasticity of plaque, vessel wall and stiffness of carotid arteriosclerosis plaque in patients with SSS-TOAST1 style cerebral infarction were lower, and the vulnerability of carotid arteriosclerosis plaque was higher. Real-time tissue elastography had some worth in evaluating the clinical course of patients after cerebral infarction.

Objectives To explore the clinical application of deceleration capacity of rate (DC), acceleration capacity of rate (AC) and heart rate variability (HRV) in children with precardial distress of unknown origin. Methods A total of 56 children with precardial distress of unknown origin and 63 healthy children aged 6 to 17 years were examined by 24 h dynamic elec-trocardiogram, and the indexes of DC and HRV were compared between these two groups. Results DC value of children with precardial distress is less than that of the control group (P<0.05), AC value is greater than that of the control group (P<0.05), and heat rate (HR) is greater than that of the control group (P<0.05). No statistical differences were observed in the indexes of HRV between the two groups. The indexes of DC show a signiifcant positive correlation with HRV in children with precardial distress(r=0.27~0.40, P<0.05), while appear a negative relation with HR (r=-0.46, P=0.000). In contrast, the indexes of AC show a signiifcant negative correlation with HRV (r=-0.57~-0.34, P<0.05), and appears a positive relation with HR(r=0.61, P=0.000). HR value is higher in male children less than 12 years old with precardial distress than that of age-matched males in control group, and RMSSD is lower than the latter. DC value of male children more than 12 years with precardial distress is lower than that of age-matched males in control group, while AC value is higher than that of the latter;DC value is signiifcant lower in fe-male children more than 12 yeares with precardial distress than that of age-matched females in the control group (P<0.05). Con-clusions The activity of vagus nerve in children with precardial distress of unknown origin is decreased. DC value is signiifcantly lower than that of control group, and shows correlation with indexes of HRV. There is no signiifcant difference in DC and HRV value between male and female children with precardial distress. DC value is lower in children aged 12 or older with precardial distress than that of age-matched children in the control group, which indicates adolescents are vulnerable to autonomic nerve functional disorder.

Objective To explore the ultrasonographic characteristics of internal jugular vein(IJV) valve insufficiency and reflux.Methods 40 healthy volunteers' bilateral IJVs were study subjects.The inner diameter,valve morphological feature,reflux distance and hemodynamic parameters in IJV were detected by color Doppler ultrasound (CDU),the contrast agents transvalvular regurgitation in IJV was monitored by contrast-enhanced ultrasound (CEUS) (with low mechanical index,MI 0.10),then analyse the results of two methods.Results Of 80 investigated IJVs,1 vein was excluded due to absence of its left valve,so 79 veins were evaluated in the study.The IJV's inner diameter on the right side was larger than on the left side,but there was no significant difference (P ＞0.05).The detection rate of IJV valve insufficiency was 31.6％ (25/79),which was higher on the right than that on the left,but without significant difference (P ＞ 0.05).The detection rate of IJV valve insufficiency was significantly higher in the group of greater than or equal to 50 years old than that in less than 50 years old(P ＜0.05).The reflux distance in IJV displayed by CDU was associated with IJV valve's function.Compaired with sufficient valves,the reflux duration time in insufficient valves during quiet respiration showed no significant difference (P ＞0.05).During Valsalvalike manoeuvres and quiet respiration,the reflux duration time in sufficient valves showed no significant difference (P ＞ 0.05).The reflux duration time in insufficient valves during Valsalva-like manoeuvres showed significantly higher than that during quiet respiration (P ＜0.01).Compaired with sufficient valves,the peak flow velocity of reflux flow in insufficient valves was significantly prolonged during quiet respiration and Valsalva-like manoeuvres (P ＜0.05,P ＜0.01,respectively).Conclusions The incidence rate of IJV valve insufficiency and reflux is high in healthy individuals.During quiet respiration and/or Valsalva-like manoeuvres,detecting the reflux distance,reflux duration time and peak flow velocity of reflux flow by CDU are valuable in evaluating IJV valve insufficiency and the degree of IJV reflux.

Objective:To investigate the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) on therapy-related leukemia (TRL).Methods:The clinical data of 14 patients with TRL who received allo-HSCT in Aerospace Central Hospital from April 2012 to February 2020 were retrospectively analyzed, and the therapeutic efficacy and survival status were also analyzed.Results:Of the 14 patients, 5 were males and 9 were females; the median age was 35 years old (12-59 years old). There were 12 patients with acute myeloid leukemia, 1 patient with chronic lymphocytic leukemia/small cell lymphoma, and 1 patient with acute lymphoblastic leukemia. At the time of transplantation, 4 patients achieved bone marrow complete remission, 3 patients achieved bone marrow partial remission, and the remaining 7 patients had no remission. Five patients received HLA-matched sibling transplantation, 9 patients received haplotype transplantation, and they all received myeloablative pretreatment schemes. All 14 patients were successfully implanted; the median engraftment time of granulocyte was 16 d (10-24 d), and the median engraftment time of platelet was 13 d (10-34 d). Grade Ⅰ-Ⅱ acute graft-versus-host disease (GVHD) occurred in 7 patients, chronic GVHD occurred in 6 patients, and grade Ⅲ intestinal GVHD occurred in 2 patients. The median follow-up time was 32 months (4-97 months). Among 14 patients, 5 patients died.Conclusion:The allo-HSCT can improve the prognosis and long-term survival rate of TRL patients.
