Objectives: The purpose of this research was to assess the effect of telehealth management via WeChat on improving the quality of life of patients after percutaneous coronary intervention (PCI).
Methods: In this study, we retrospectively collected the clinical data of 118 patients who underwent PCI and received remote health management from our hospital via WeChat from June 2021 to September 2021 (WeChat group). The clinical data of 114 patients who underwent PCI but did not receive remote health management from our hospital from September 2020 to December 2020 were also collected (conventional group).
Since the extreme service conditions, the serious failure problems caused by wear and corrosion are often encountered in the service process for aeronautical components. Laser shock processing (LSP) is a novel surface-strengthening technology to modify microstructures and induce beneficial compressive residual stress on the near-surface layer of metallic materials, thereby enhancing mechanical performances. In this work, the fundamental mechanism of LSP was summarized in detail.

In this work, LSP was used to treat titanium alloy Ti-13Nb-13Zr experimental coupons, and the microstructural response and surface mechanical properties of the Ti-13Nb-13Zr experimental coupons were investigated. After the LSP treatment, the X-ray diffraction (XRD) peaks were shifted without any new phase formation.

Environmental protection expenditure is an important means for local governments to improve environmental quality; it plays a crucial role in guiding market investment, providing environmental treatment funds and energy conservation and utilization. Based on a sample of 286 prefecture-level cities in China from 2007 to 2017, this study analyzes environmental governance effects of local environmental protection expenditure while considering the time duration, regional differences, and spatial spillover characteristics of industrial pollution emissions.

This study investigated for the first time the protective effect of mitochondrial division inhibitor-1 (mdivi-1) against cerebral edema induced by simulated high-altitude exposure in mice. It was found that mdivi-1 effectively inhibited phosphorylation of dynamin-related protein-1 (Drp1), reduced expression of AQP4, decreased secretion of IL-6 and TNF-α, and alleviated cerebral edema in mice.

The results showed that IH preconditioning protected HepG2 cells against oxygen and glucose deprivation/reperfusion (OGD/Rep)-induced injury and protected WRL68 cells against HO or AMA-induced oxidative injury. IH preconditioning up-regulated the protein level of NRF-1, PINK1, Parkin, and LC3 II, promoted the recruitment of the cytosolic Parkin, indicating the initiation of the PINK1/Parkin-mediated mitophagy in WRL68 cells.

Purpose: To compare the mechanical properties of 3D-printed titanium meshes and pre-shaped titanium meshes, and to evaluate the effects of 3D-printed titanium meshes on cell proliferation and differentiation.
Methods: 3D- printed titanium meshes were produced and prepared with laser printing machine. The mechanical properties were analyzed by static tension and compression load test.
Background: Cleistanthin A (CleA), a natural diphyllin glycoside, has been shown to suppress the invasion of cancer cells, but the underlying mechanisms remain unclear. Here, the inhibitory effect of CleA on the invasion of MDA-MB-231 human breast cancer cells was investigated, and the mechanisms involved were clarified.
Methods: Cell viability was studied by MTT assay.
In response to the increasing pressure of global resource management and environmental issues and a slowdown in the related economic growth, China has proposed an inclusive green growth strategy based on coordination between society, the economy, and the environment. The alignment of resources with the socio-economic development goals is a key issue that must be addressed for inclusive green growth. A comprehensive directional distance function and slacks-based measure model are proposed to evaluate the inclusive green growth levels of 285 cities in China from 2003 to 2015.

But until now, the transcriptional regulation of these two genes under normal physiological conditions are not well understood. In this study, the transcriptional regulation of PINK1 and Parkin genes by nuclear respiratory factor 1 (NRF-1) and its effect on PINK1/Parkin-mediated mitophagy were studied.
View Article and Find Full Text PDFBackground: It has been reported that brusatol (BRU) reduces cellular reactive oxygen species (ROS) level under hypoxia; here the protective effect of BRU against oxygen-glucose deprivation/reoxygenation (OGD-R)-induced injury in HepG2 cells and against anoxia/reoxygenation (A/R)-induced injury in rat liver mitochondria was investigated.
Materials And Methods: OGD-R-induced HepG2 cell viability loss was detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide and trypan blue staining. Mitochondrial ROS level in HepG2 cells was measured by MitoSOX staining.

It has been reported that ammonia produced by glutaminolysis activates the HIF-1 pathway in several types of cancer cells, but the underlying mechanisms remain unclear. In this study, the effects of ammonia on the activation of HIF-1 pathway and glycolysis in MDA-MB-231 breast cancer cells were investigated and the underlying mechanisms involved were elucidated. The results showed that NHCl concentration-dependently increased the protein level of HIF-1α and enhanced the transactivation activity of HIF-1 in MDA-MB-231 cells.
