Coronavirus disease (COVID-19) is a new infectious disease associated with high mortality, and traditional Chinese medicine decoctions (TCMDs) have been widely used for the treatment of patients with COVID-19 in China; however, the impact of these decoctions on severe and critical COVID-19-related mortality has not been evaluated. Therefore, we aimed to address this gap. In this retrospective cohort study, we included inpatients diagnosed with severe/critical COVID-19 at the Tongren Hospital of Wuhan University and grouped them depending on the recipience of TCMDs (TCMD and non-TCMD groups). We conducted a propensity score-matched analysis to adjust the imbalanced variables and treatments and used logistic regression methods to explore the risk factors associated with in-hospital death. Among 282 patients with COVID-19 who were discharged or died, 186 patients (66.0%) received TCMD treatment (TCMD cohort) and 96 (34.0%) did not (non-TCMD cohort). After propensity score matching at a 11 ratio, 94 TCMD users were matched to 94 non-users, and there were no significant differences in baseline clinical variables between the two groups of patients. The all-cause mortality was significantly lower in the TCMD group than in the non-TCMD group, and this trend remained valid even after matching (21.3% [20/94] vs. 39.4% [37/94]). Multivariable logistic regression model showed that disease severity (odds ratio 0.010; 95% CI 0.003, 0.037; [Formula see text]¡ 0.001) was associated with increased odds of death and that TCMD treatment significantly decreased the odds of in-hospital death (odds ratio 0.115; 95% CI 0.035, 0.383; [Formula see text]¡ 0.001), which was related to the duration of TCMD treatment. Our findings show that TCMD treatment may reduce the mortality in patients with severe/critical COVID-19.Neohesperidin has anti-oxidative and anti-inflammatory properties and exerts extensive therapeutic effects on various cancers. In this study, the osteosarcoma cell lines were exposed to different concentrations of neohesperidin. Cell proliferation and viability were assessed by CCK-8 and colony-formation assays. The role of neohesperidin in cell cycle progression and apoptosis were analyzed by flow cytometry and western blotting. To identify autophagosomes and autolysosomes, we used a tandem GFP-mRFP-LC3B lentiviral construct. selleck chemicals In addition, autophagy was evaluated by examining autophagosome formation using transmission electron microscopy. Intracellular reactive oxygen species (ROS) production was detected by fluorescence microscopy and flow cytometry. Subsequently, the activation of the ROS/JNK signaling pathway was investigated. Neohesperidin could inhibit proliferation and induce apoptosis in SJSA and HOS cells. The formation of autophagosomes indicated that autophagy occurred in neohesperidin-treated cells and the apoptotic effect of neohesperidin was significantly increased after the use of autophagy inhibitors. Subsequently, we found that neohesperidin-induced apoptosis and autophagy were related to the increase in ROS generation and were significantly inhibited by GSH. Moreover, neohesperidin induced activation of the c-Jun N-terminal kinase (JNK) signaling pathway and inhibition of JNK with SP600125 attenuated neohesperidin-induced apoptosis and autophagy simultaneously. Our data indicated that neohesperidin caused G2/M phase arrest and induced apoptosis and autophagy by activating the ROS/JNK pathway in human osteosarcoma cells, suggesting that neohesperidin is a potential drug candidate for the treatment of osteosarcomas.The unclear pathogenesis mechanisms and resistance of cancer cells to chemical drugs serious limits the development of effective treatment strategies for non-small cell lung cancer (NSCLC). In this study, we managed to investigate this issue, and identify potential cancer associated biomarkers for NSCLC diagnosis, prognosis and treatment. This study found that miR-6734-3p was downregulated in both NSCLC clinical specimens (tissues and serum) and cells, compared to the normal tissues and cells. Next, upregulation of miR-6734-3p inhibited cancer formation and progression in NSCLC cells in vitro and in vivo. Conversely, miR-6734-3p ablation had opposite effects and facilitated NSCLC development. In addition, miR-6734-3p bound to the 3' untranslated region (3'UTR) of zinc finger E-box binding homeobox 2 (ZEB2) mRNA to suppress its expressions in NSCLC cells. Interestingly, the inhibiting effects of miR-6734-3p overexpression on NSCLC progression were abrogated by upregulating ZEB2. Furthermore, both upregulated miR-6734-3p and silencing of ZEB2 increased cisplatin-sensitivity in cisplatin-resistant NSCLC (CR-NSCLC) cells. Taken together, miR-6734-3p played an anti-tumor role to hinder cancer development and enhanced the cytotoxic effects of cisplatin treatment on NSCLC cells by downregulating ZEB2.Adenoid cystic carcinoma (AdCC) is a rare epithelial neoplasm of the head and neck, most commonly found in the salivary glands. Orbital AdCC is an uncommon clinical entity arising from the lacrimal glands, however primary orbital AdCC has been previously described in a small number of case reports. The exact origin of the neoplasm with uninvolved lacrimal gland in the orbit is unknown, however it may arise from ectopic lacrimal or salivary gland tissue, or extension from nearby epithelial structures. We describe the clinical characteristics, investigations and management of a 55-year-old man presenting with vertical diplopia, found to have left posterior orbital AdCC invading the skull base with intracranial extension involving the inferotemporal fossa, pterygopalatine fossa, left carotid artery, cavernous sinus and temporal lobe dura, without clinical or radiological lacrimal gland involvement or systemic metastases.Despite over 25 years of safe deployment of genetically engineered crops, the number, complexity, and scope of regulatory studies required for global approvals continue to increase devoid of adequate scientific justification. Recently, there have been calls to further expand the scope of study and data requirements to improve public acceptance. However, increased regulation can actually generate consumer distrust due to the misperception that risks are high. We believe risk-disproportionate regulation as a means to advocate for acceptance of technology is counterproductive, even though some regulatory authorities believe it part of their mandate. To help avoid public distrust, the concept of regulatory transparency to demystify regulatory decision-making should be extended to clearly justifying specific regulatory requirements as 1) risk-driven (i.e., proportionately addressing increased risk compared with traditional breeding), or 2) advocacy-driven (i.e., primarily addressing consumer concerns and acceptance).
