Intelligent condition monitoring with CNN and signal enhancement for undersampled signals.

High-frequency signals like vibration and acoustic emission are crucial for condition monitoring, but their high sampling rates challenge data acquisition, especially for online monitoring. Our research developed a novel method for condition identification in undersampled signals using a modified convolutional neural network integrated with a signal enhancement approach. A frequency-domain filtering is applied to suppress similar sidebands and obtain more discriminative features of different conditions, followed by an interpolation-based upsampling in the time domain to restore the signal length and strengthen the low-frequency harmonic information.

Downregulation of circFASTKD1 ameliorates myocardial infarction by promoting angiogenesis.

Circular RNAs (circRNAs), a novel class of endogenous long non-coding RNAs, have attracted considerable attention due to their closed continuous loop structure and potential clinical value. In this study, we investigated the function of circFASTKD1 in vascular endothelial cells. CircFASTKD1 bound directly to miR-106a and relieved its inhibition of Large Tumor Suppressor Kinases 1 and 2, thereby suppressing the Yes-Associated Protein signaling pathway.

External Validation of Survival-Predicting Models for Acute Myocardial Infarction with Extracorporeal Cardiopulmonary Resuscitation in a Chinese Single-Center Cohort.

BACKGROUND This study was designed as an external evaluation of potentially relevant models for acute myocardial infarction (AMI) with extracorporeal cardiopulmonary resuscitation (E-CPR). MATERIAL AND METHODS Twenty AMI adults that met criteria were retrospectively analyzed from January 2009 to January 2015. Six possible models - ENCOURAGE, SAVE, ECPR, GRACE, SHOCK, and a simplified risk chart - were identified by literature review and model scores calculated based on original data.

Extracorporeal Membrane Oxygenation Outcomes in Acute Respiratory Distress Treatment: Case Study in a Chinese Referral Center.

BACKGROUND No definitive conclusions have been drawn from the available data about the utilization of extracorporeal membrane oxygenation (ECMO) to treat severe acute respiratory distress syndrome (ARDS). The aim of this study was to review our center's experience with ECMO and determine predictors of outcome from our Chinese center. MATERIAL AND METHODS We retrospectively analyzed a total of 23 consecutive candidates who fulfilled the study entry criteria between January 2009 and December 2015.

Performance of Multiple Risk Assessment Tools to Predict Mortality for Adult Respiratory Distress Syndrome with Extracorporeal Membrane Oxygenation Therapy: An External Validation Study Based on Chinese Single-center Data.

Background: There has been no external validation of survival prediction models for severe adult respiratory distress syndrome (ARDS) with extracorporeal membrane oxygenation (ECMO) therapy in China. The aim of study was to compare the performance of multiple models recently developed for patients with ARDS undergoing ECMO based on Chinese single-center data.

Methods: A retrospective case study was performed, including twenty-three severe ARDS patients who received ECMO from January 2009 to July 2015.

Insight into Metalized Interfaces in Nano Devices by Surface Analytical Techniques.

Connections between metals and heterogeneous solid state materials form buried interfaces. These ubiquitous structures play an essential role in determining the performances of many nano- and microdevices. However, the information about the chemistry, structure, and properties of these real interfaces is intrinsically difficult to extract by traditional techniques.

[The use of extracorporeal membrane oxygenation in sustaining pulmonary function patients with influenza A H1N1].

Objective: To summarize the clinical method and initial experience of extracorporeal membrane oxygenation (ECMO) supportive treatment in influenza A H1N1 serious patients.

Methods: In 5 critically ill patients with influenza A H1N1, their arterial oxygen saturation was 0.70 to 0.

Video-assisted thoracoscopic surgery for congenital heart disease.

We report our experience with video-assisted thoracoscopy in the surgical closure of heart septal defects. Nine patients, aged 10 to 26 years, underwent operation for closure of an atrial septal defect; and 3, aged 10 to 22 years, for closure of a ventricular septal defect. Three minithoracotomies with a diameter of 2 to 3 cm were made in the fourth intercostal space of the right parasternum and the fourth and seventh intercostal spaces of the right middle axillary line, respectively.
