[Mechanism of tetramethylpyrazine attenuates inflammatory injury in endothelial cells by activating the SIRT1 signaling pathway].

Objectives: To study the effects and mechanisms of tetramethylpyrazine (TMP) on tumor necrosis factor-α (TNF-α)-induced inflammatory injury in human coronary artery endothelial cells (HCAEC).

Methods: HCAEC were randomly divided into four groups: the control group (no treatment), the model group (treated with TNF-α, 50 ng/mL for 24 hours), the TMP group (pre-treated with TMP, 80 μg/mL for 12 hours followed by TNF-α treatment for 24 hours), and the SIRT1 inhibitor group (pre-treated with TMP and the specific SIRT1 inhibitor EX527 for 12 hours followed by TNF-α treatment for 24 hours). Cell viability was assessed using the CCK-8 method, lactate dehydrogenase (LDH) activity was measured using an LDH assay kit, reactive oxygen species (ROS) levels were observed using DCFH-DA staining, expression of pyroptosis-related proteins was detected by Western blot, and SIRT1 expression was analyzed using immunofluorescence staining.

Ling-Gui-Zhu-Gan decoction ameliorates nonalcoholic fatty liver disease via modulating the gut microbiota.

Unlabelled: Numerous studies have supported that nonalcoholic fatty liver disease (NAFLD) is highly associated with gut microbiota dysbiosis. Ling-Gui-Zhu-Gan decoction (LG) has been clinically used to treat NAFLD, but the underlying mechanism remains unknown. This study investigated the therapeutic effect and mechanisms of LG in mice with NAFLD induced by a high-fat diet (HD).

Microencapsulation of blueberry anthocyanins by spray drying with soy protein isolates/high methyl pectin combination: Physicochemical properties, release behavior in vitro and storage stability.

Eleven anthocyanins in the blueberry anthocyanins powders (BAP) were identified and quantified by HPLC-DAD-ESI-MS. BAP microcapsules (MBAP) were produced by spray drying using high methyl pectin (HMP) combined with whey protein isolates (WPI) or soy protein isolates (SPI) in different proportions as wall materials. Generally, SPI/HMP combination was more efficient in increasing the encapsulation efficiency and T, and in decreasing the particle size and hygroscopicity of the microcapsules than WPI or HMP or WPI/HMP combination.

Structural and Functional Modulation of Gut Microbiota by Jiangzhi Granules during the Amelioration of Nonalcoholic Fatty Liver Disease.

Recently, accumulating evidence revealed that nonalcoholic fatty liver disease (NAFLD) is highly associated with the dysbiosis of gut microbiota. Jiang Zhi Granule (JZG), which is composed of five widely used Chinese herbs, has shown hypolipidemic effect, while whether such effect is mediated by gut microbiota is still unclear. Here, we found that both low and high doses of JZG (LJZ and HJZ) could improve hepatic steatosis and function, as well as insulin resistance in NAFLD mice.

The CDK4/6 inhibitor in HR-positive advanced breast cancer: A systematic review and meta-analysis.

Background: Recently, several high-quality clinical randomized controlled trials (RCTs) have identified that cyclin-dependent kinases (CDKs) 4/6 inhibitors obtained a great safety and efficacy, which can be consequently applied as a combination therapy with letrozole or fulvestrant for women who had advanced breast cancer and progressed while receiving endocrine therapy. In this systemic review, we performed a meta-analysis to explore whether CDK4/6 inhibitors had a significantly benefit to treating hormone receptor-positive (HR-positive)/human epidermal growth factor receptor 2 negative (HER2-negative) advanced breast cancer.

Methods: The data for meta-analysis were collected from MEDLINE, EMBASE, and Cochrane Library from January 1980 to December 2017, and eventually 3182 patients from 6 RCTs were included.

Fates of donor and recipient mitochondrial DNA during generation of interspecies SCNT-derived human ES-like cells.

To investigate nuclear donor and cytoplast recipient mitochondria fate and their effects on generation of interspecies somatic cell nuclear transfer (iSCNT)-derived human embryonic stem (ES)-like cells, iSCNT embryos were reconstructed between enucleated goat oocytes and human neural stem cells (hNSCs). A total of 10.74% cleaved embryos (13/121) developed to blastocyst stage.

Brow fat pad flap transfer for repairing depressed deformity of the upper eyelids.

Objective: To study the new surgical approach to repair depressed deformity of the upper eyelids by transferring brow fat pad flap that retains blood supply and similar construction with the orbital septum.

Method: An incision was made in the inferior margin of the brow to dissect and expose the brow fat pad under the orbicular muscle of the eye and frontal muscle plane in the lateral superior orbit, and the flap was removed from above the periosteum and pedicled under the orbital rim. Through the incision in the double-eyelid fold, a tunnel was dissected upward from the plane under the orbicular muscle to reach the brow incision.
