Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

In recent years,the use of bioprosthetic mitral valves has been increasing,leading to a growing number of patients experiencing bioprosthesis degeneration,significantly impacting their quality of life.The high risk of reoperation has deprived many patients with mitral bioprosthesis degeneration of the opportunity for a second surgery.With the rapid development of interventional procedures in our country,transcatheter mitral valve-in-valve replacement is gradually being accepted by a large number of patients with bioprosthesis degeneration.We report a case of transcatheter mitral valve-in-valve replacement via transseptal puncture.The surgical plan was carefully formulated based on preoperative CT evaluation,and the patient underwent the procedure smoothly with no significant adverse events postoperatively.Transcatheter mitral valve-in-valve replacement may be a better alternative for patients at high risk of mitral bioprosthesis degeneration.

Liver cancer is the most lethal form of cancer and carries a high risk of death around the world. Goniothalamin (GTN) is a styryl-lactone that possesses antiproliferative and apoptotic activity. The molecular action of GTN is not yet fully evaluated. Thus, our research has been intended to assess the chemopreventive and apoptotic activities of diethylnitrosamine (DEN)-induced hepatocellular carcinoma (HCC) in rats. Rats were separated into 4 groups: control, DEN only, DEN + GTN (30 mg/kg bw), and GTN (30 mg/kg bw) alone. We evaluated body weight, liver weight, tumor incidence, hepatic toxic markers, antioxidants, inflammatory cytokines, histopathology, immunohistochemistry, and Western blot studies. DEN lessened body weight, antioxidants, and apoptosis, whereas it elevated tumor incidence, toxic markers, cytokines, and Bcl-2 expression. GTN treatment maintains body weight, liver weight, and antioxidant levels, and it also prevents tumor incidence, oxidative stress, toxic markers, pro-inflammatory cytokines, and histological changes. It triggers apoptosis by constraining Bcl-2 and elevating caspase-3 levels. GTN also attenuated the P13K/ AKT signaling which enhanced apoptosis. These findings revealed that GTN subdues the P13K/AKT pathway and has auspicious chemopreventive and apoptotic actions in DEN-induced HCC. Therefore, GTN would be suggested as a new medicine in natural remedies for liver cancer.
