Patellar fractures are characterized by injuries to the extensor and typically require surgical fixation. Among the methods used for fixation, the most common is the modified AO tension-band wiring technique. However, using this technique, implant migration occurs due to the lack of connections between the K-wires and the tension-band wire, which causes irritation and reduces fracture stability. Recently, new methods for tension-band wiring have been developed in which tension bands lock the K-wires through an attached "ring" to prevent migration...

Hand, foot and mouth disease (HFMD) is a serious, highly contagious disease. HFMD caused by Enterovirus 71 (EV71), results in severe complications and even death. The pivotal role of EV71 3C(pro) in the viral life cycle makes it an attractive target for drug discovery and development to treat HFMD. In this study, we identified novel EV71 3C(pro) inhibitors by docking-based virtual screening. Totally 50 compounds were selected to test their inhibitory activity against EV71 3C(pro). The best inhibitor DC07090 exhibited the inhibition potency with an IC50 value of 21...

Combination therapy with more than one therapeutic agent can improve therapeutic efficiency and decrease drug resistance. In this study, the interactions of human serum albumin (HSA) with individual or combined anticancer drugs, (-)-epigallocatechin-3-gallate (EGCG) and 5-fluorouracil (FU), were investigated by fluorescence and circular dichroism (CD) spectroscopy. The results demonstrated that the interaction of EGCG or FU with HSA is a process of static quenching and EGCG formed a more stable complex. The competitive experiments of site markers suggested that both anti-carcinogens mainly bound to site I (subdomain IIA)...

Epigallocatechin-3-gallate (EGCG) has been shown to possess anti-inflammatory effects. Microcystin-LR (MC-LR) is a potent toxin and our past research suggested that it also mediated human umbilical vein endothelial cell (HUVEC) injury. The aim of this study was to investigate the effects of EGCG on MC-LR-induced oxidative stress and inflammatory responses in HUVECs. HUVECs were stimulated with MC-LR in the presence or absence of EGCG. MC-LR (40 μM) significantly increased cell death and decreased cell viability, migration, and tube formation, whereas EGCG (50 μM) inhibited these effects...

BACKGROUND: We tested the hypothesis that an electronic alert for a "double low" of mean arterial pressure less than 75 mmHg and a bispectral index less than 45 reduces the primary outcome of 90-day mortality. METHODS: Adults having noncardiac surgery were randomized to receive either intraoperative alerts for double-low events or no alerts. Anesthesiologists were not blinded and not required to alter care based upon the alerts. The primary outcome was all-cause 90-day mortality...
