Backgrounds: Metastasis associated lung adenocarcinoma transcript 1 (MALAT1) is an lncRNA that has been suggested as a key regulator in the onset of atherosclerosis (AS). This study described the role of MALAT1 in oxidized low density lipoprotein (ox-LDL)-induced endothelial cells death. Methods: Human umbilical vein endothelial cells (HUVECs) were subjected to ox-LDL, before which the expression of MALAT1 was overexpressed by transfection. CCK-8 assay, flow cytometer detection, and western blot were carried out to evaluate cell viability, apoptosis and autophagy. qRT-PCR and western blot analyses were performed to investigate the regulatory relationship between MALAT1, Matrix Gla protein (MGP) and mTOR signaling to decode the underlying mechanism. Results: Up-regulation of MALAT1 attenuated ox-LDLinduced HUVECs lose, as evidenced by the promoted cell viability, and the decreased apoptosis rate. This finding was coupled with the down-regulated p53, Bax, active-caspase-3, Beclin-1 and LC3-II, as well as the up-regulated Bcl-2 and p62. Meanwhile, MALAT1 upregulation promoted the phosphorylation of p70S6K and mTOR, and the expression of MGP. MGP up-regulation exhibited MALAT1-like propoties in preventing ox-LDL-induced cell death and mTOR deactivation. Of contrast, MGP silence affected HUVECs survival and mTOR signaling resulted in contrary impacts. Conclusion: The present work described that MALAT1 up-regulation prevented ox-LDL-mediated apoptosis and autophagy in HUVECs. The protective effects of MALAT1 might be partially via up-regulating MGP, which led to the activation of mTOR signaling.

Background: The evidence of Acupuncture combined with speech rehabilitation training for post-stroke dysarthria is insufficient and there is no consensus on its efficacy. Methods: We searched seven Chinese and English medicine databases for randomized controlled trials (RCTs) from their inception to November 2019. The primary outcome measure was the clinical response rate, assessed with the Frenchay Dysarthria Assessment (FDA) tool. We assessed risk of bias using the Cochrane risk-of-bias tool. We used GRADE to assess the certainty of evidence (CoE). Results: Thirty studies were included in this systematic review, 23 of which were pooled in meta-analysis. Acupuncture combined with speech rehabilitation training is likely beneficial for was response rate (n = 1685; RR = 1.37; 95% CI [1.29, 1.46], P < 0.01, I2 = 34%; 17 studies, low CoE) compared to speech rehabilitation treatment alone. Conclusion: The combination of acupuncture and speech rehabilitation training may improve total response rate of stroke patients with dysarthria. However, more RCTs with rigorous study design and validated outcome measures are needed to confirm the evidence.

The aim of this work is to evaluate the potential of oriental melon (Cucumis melo L. var. makuwa Makino) seeds for the management of type 2 diabetes by controlling glucose absorption. The ${\alpha}$-glucosidase and ${\alpha}$-amylase inhibitory effects of the hexane extracts from oriental melon seeds were investigated. A bioassay-guided fractionation technique was used to elucidate the principal active components. The results show that the hexane extract from oriental melon seeds exhibited high inhibitory activities against ${\alpha}$-glucosidase and ${\alpha}$-amylase. The hexane extract was further fractionated into four sub-fractions. Among them, the sub-fraction F-1 exhibited the most potent anti-diabetic effect. The active components were isolated and identified by gas chromatography/mass spectroscopy (GC-MS). Free fatty acids showed significant hypoglycemic activity (p < 0.001) and fatty acid composition influenced enzyme inhibitory activities. These results suggest that oriental melon seeds could be used to prevent type 2 diabetes.
