“…Ten studies from 11 different ethnic groups were found [13, 15, 16, 25–28], which also described the angiographic involvement pattern based on the classification of Numano et al [19]. In eight groups, type V was the most common pattern, as seen in the present study, but in the other three groups, type I was the most common pattern (Table 4).…”

BackgroundWe aimed to investigate the clinical characteristics of 411 Chinese Takayasu’s arteritis (TAK) patients using a retrospective analysis.MethodsWe retrospectively reviewed 810 medical charts of patients with a diagnosis of TAK who were admitted to Peking Union Medical College Hospital from 1990 to 2014. 411 patients with a complete dataset were finally included in the analysis. The demographic data, clinical features, angiographic patterns, and TAK-related surgical procedures were collected and analyzed.ResultsThe median age at disease onset was 23 (18, 30) years old, with a median disease duration of 21 (6, 60) months; 325 (79.1%) were female. The angiographic involvement pattern was type I in 91 (22.1%) patients, type IIa in 16 (3.9%) patients, type IIb in 16 (3.9%) patients, type III in 12 (2.9%) patients, type IV in 26 (6.3%) patients, and type V in 250 (60.8%) patients. Subclavian arteries (79.8%) were the most commonly involved, followed by carotid arteries (79.1%). The occurrence rate (4.1%) of aortic aneurysm in this study was low; 119 operations and interventions were performed. The most common cause of death in this study was heart failure.ConclusionSubclavian arteries, carotid arteries, and type V were the most frequently involved arteries and angiography pattern in this Chinese TAK study. The difference in angiographic features may lead to differences in clinical manifestations. Surgical operation and interventions should be performed at different stages of the disease course.

“…The occurrence of hypertension could severely worsen TAK prognosis and may be a significant prognostic predictor of outcomes [ 11 ]. Furthermore, uncontrolled blood pressure was associated with a higher 5 years all-cause mortality risk than that in the healthy population, despite effective control of disease activity [ 12 , 13 ]. Thus, comprehensive understanding of the disease characteristics of TAK patients with hypertension is very essential.…”

Background Hypertension occurred in 30–80% of Takayasu arteritis (TAK) patients around the world and the occurrence of hypertension might worsen the disease prognosis. This study aimed to investigate the clinical characteristics and imaging phenotypes, as well as their associations with events free survival (EFS) in Chinese TAK patients with hypertension. Methods This current research was based on a prospectively ongoing observational cohort-the East China Takayasu Arteritis (ECTA) cohort, centered in Zhongshan Hospital, Fudan University. Totally, 204 TAK patients with hypertension were enrolled between January 2013 and December 2019. Clinical characteristics and imaging phenotypes of each case were evaluated and their associations with the EFS by the end of August 30, 2020, were analyzed. Results Severe hypertension accounted for 46.1% of the entire population. Three specific imaging phenotypes were identified: Cluster 1: involvement of the abdominal aorta and/or renal artery (27.5%); Cluster 2: involvement of the ascending aorta, thoracic aorta, the aortic arch, and/or its branches (18.6%); and Cluster 3: combined involvement of Cluster 1 and 2 (53.9%). Clinical characteristics, especially hypertensive severity, differed greatly among the three imaging clusters. In all, 187 patients were followed up for a median of 46 (9–102) months; 72 events were observed in 60 patients (1–3 per person). The overall blood pressure control rate was 50.8%, and the EFS was 67.9% by the end of the follow-up. Multivariate Cox regression indicated that controlled blood pressure (HR = 2.13, 95% CI 1.32–3.74), Cluster 1 (HR = 0.69, 95% CI 0.48–0.92) and Cluster 3 (HR = 0.72, 95% CI 0.43–0.94) imaging phenotype was associated with the EFS. Kaplan–Meier curves showed that patients with controlled blood pressure showed better EFS (p = 0.043). Furthermore, using cases with Cluster 1 imaging phenotype and controlled blood pressure as reference, better EFS was observed in patients with Cluster 2 phenotype and controlled blood pressure (HR = 2.21, 95%CI 1.47–4.32), while the case with Cluster 1 phenotype plus uncontrolled blood pressure (HR = 0.64, 95%CI 0.52–0.89) and those with Cluster 3 phenotype and uncontrolled blood pressure (HR = 0.83, 95%CI 0.76–0.92) suffered worse EFS. Conclusion Blood pressure control status and imaging phenotypes showed significant effects on the EFS for TAK patients with hypertension.

“…12 have obtained the fluctuation in the gross domestic product that the width of the distribution scales as a power law of the gross domestic product with a scaling exponent β = 0.15. Otherwise, many works 5,6,7,13,14 have reported that the price fluctuations follow the anomalous power law from the stochastic time evolution equation, i.e. Langevin-type equation.…”

We study the tick dynamical behavior of the bond futures in Korean Futures Exchange(KOFEX) market. Since the survival probability in the continuous-time random walk theory is applied to the bond futures transaction, the form of the decay function in our bond futures model is discussed from two kinds of Korean Treasury Bond(KTB) transacted recently in KOFEX.The decay distributions for survival probability are particularly displayed stretched exponential forms with novel scaling exponents β = 0.82(KTB 203) and β = 0.90(KTB112), respectively, for our small time intervals. We obtain the scaling exponents for survival probability ǫ = 17 and 18 decayed rapidly in large time limit, and our results are compared with recent numerical calculations.
