Melatonin ameliorates bupivacaine-induced spinal neurotoxicity in rats by suppressing neuronal NLRP3 inflammasome activation.

Bupivacaine is a common local anesthetic that causes neurotoxicity when used at clinical concentrations. Melatonin (MT), is a potent neuroprotective molecule. The study aimed to characterize the neuroprotective effects of MT on spinal neurotoxicity induced by bupivacaine in rats.

Standardization of critical care management of non-critically ill patients with COVID-19.

The large global outbreak of coronavirus disease 2019 (COVID-19) has seriously endangered the health care system in China and globally. The sudden surge of patients with severe acute respiratory syndrome coronavirus 2 infection has revealed the shortage of critical care medicine resources and intensivists. Currently, the management of non-critically ill patients with COVID-19 is performed mostly by non-intensive care unit (ICU) physicians, who lack the required professional knowledge, training, and practice in critical care medicine, especially in terms of continuous monitoring of the respiratory function, intervention, and feedback on treatment effects.

[Spatiotemporal variations of natural wetland CH4 emissions over China under future climate change].

Based on a new process-based model, TRIPLEX-GHG, this paper analyzed the spatio-temporal variations of natural wetland CH4 emissions over China under different future climate change scenarios. When natural wetland distributions were fixed, the amount of CH4 emissions from natural wetland ecosystem over China would increase by 32.0%, 55.

Hemin inhibits NLRP3 inflammasome activation in sepsis-induced acute lung injury, involving heme oxygenase-1.

NLRP3 inflammasome activation contributes to acute lung injury (ALI), accelerating caspase-1 maturation, and resulting in IL-1β and IL-18 over-production. Heme oxygenase-1 (HO-1) plays a protective role in ALI. This study investigated the effect of hemin (a potent HO-1 inducer) on NLRP3 inflammasome in sepsis-induced ALI.

[Artesunate suppresses human endometrial carcinoma RL95-2 cell proliferation by inducing cell apoptosis].

Objective: To investigate the inhibitory effect of artesunate on human endometrial carcinoma RL95-2 cell line proliferation in vitro and the possible mechanisms.

Methods: The inhibitory effect of artesunate on the cell proliferation was assessed with MTT assay. Transmission electron miscrosopy was used to observe the morphological change of the cells after the treatment.

[Molecular biologic study on heme oxygenase in experiment pulmonary thromboembolism].

Objective: To investigate the changes in heme oxygenase (HO) system expression in pulmonary thromboembolism (PTE), and the influence to the pulmonary artery blood pressure as a result of the changes.

Methods: In 23 healthy adult male dogs, autologous thrombus was injected through the jugular vein to reproduce the PTE model. They were divided randomly into 4 groups: A (pulmonary embolism 3 hours group), B (pulmonary embolism 8 hours group), C (pulmonary embolism 24 hours group) and D (control group).

Interaction between cisplatin, 5-fluorouracil and vincristine on human hepatoma cell line (7721).

AIM:To evaluate the killing effects of CDDP, 5-Fu and VCR on human hepaoma cell line (7721).METHODS:The median-effect principle was used.RESULTS:Killing effects of the individual drug were enhanced as the median concentration increased.
