Aortic dissection is a kind of fatal cardiovascular disease, and the apoptosis of aortic vascular smooth muscle plays an important role in aortic dissection.The new discovered Hippo-YAP signal transduction pathway is significant in regulation of the function of vascular smooth muscle, and it can cause many cardiovascular diseases.This paper aims to review the present studies of the mechanism of the apoptosis of aortic vascular smooth muscle and Hippo-YAP signaling pathway in the pathogenesis of cardiovascular diseases, especially the aortic dissection.

Background/Aims: The aim of this study was to analyze the chronological changes in postoperative complications in surgical ulcerative colitis patients over the past decade in China and to investigate the potential parameters that contributed to the changes. Methods: Ulcerative colitis patients who underwent surgery during 2008–2017 were retrospectively enrolled from 13 hospitals in China. Postoperative complications were compared among different operation years. Risk factors for complications were identified by logistic regression analysis. Results: A total of 446 surgical ulcerative colitis patients were analyzed. Fewer short-term complications (24.8% vs. 41.0%, P=0.001) and more laparoscopic surgeries (66.4% vs. 25.0%, P<0.001) were found among patients who received surgery during 2014–2017 than 2008–2013. Logistic regression suggested that independent protective factors against short-term complications were a higher preoperative body mass index (odds ratio [OR], 0.870; 95% confidence interval [CI], 0.785–0.964; P=0.008), laparoscopic surgery (OR, 0.391; 95% CI, 0.217–0.705; P=0.002) and elective surgery (OR, 0.213; 95% CI, 0.067–0.675; P=0.009). The chronological decrease in short-term complications was associated with an increase in laparoscopic surgery. Conclusions Our data revealed a downward trend of short-term postoperative complications among surgical ulcerative colitis patients in China during the past decade, which may be due to the promotion of minimally invasive techniques among Chinese surgeons.

Objective To explore the genetic mutation spectrum of patients with hypertrophic cardiomyopathy (HCM) and analysis the correlation of genotype phenotype.Methods Collect peripheral venous blood of the 51 cases unrelated HCM patients(35 male and 16 female) in the Beijing Anzhen Hospital of Capital Medical University from 2013 to 2016.Sequence whole exons of human and analysis seven major mutations of HCM including:MYBPC3、MYH7 、TNNT2、TNNI3 、MYL2 、TPM1 and ACTC1.Then compare the results with clinical characteristics.Results 24 patients(47.1％) had 22 kinds of pathogenicity or possibly pathogenicity mutations.The 90.9％ (20/22) of mutations only occurred one time,except MYH7 gene's 663 amino acid and the TNND gene's 157 amino acid which had twice.The mutations of MYBPC3,MYH7,TNNT2,TNNI3,MYL2,TPM1 and ACTC1 accounted for 45.8％ (11/24),20.8％ (5/24),12.5％ (3/24),8.3％ (2/24),8.3％ (2/24),4.2％ (1/24),and 0 respectively.No amphimutation had been found that causes illness or possibly.Through the comparison of clinical features between Genotype positive(24 cases) and negative(27 cases) patients:the incidence of syncope(19.6％ vs.7.8％,P ＜ 0.05),the largest left ventricular wall thickness[(22.8 ± 2.6) mm vs.(20.0 ± 3.4) mm,P ＜ 0.05],family history of HCM(20.8％ vs.0,P ＜0.05),percentage of apical hypertrophy(25.5％ vs.11.8％,P ＜ 0.05);The ratio of left ventricular outflow tract obstruction in MYH7 group was higher than MYBPC3 group (80.0％ vs.18.2％,P ＜ 0.05).Conclusion MYBPC3 is the most common mutation gene in HCM patients.Phenotype is more severe in geuotype positive patients than in genotype negative patients.Relationship between specific gene mutations and clinical phenotype requires further study.
