Simulation analysis of the three-party evolutionary game of green building market players under carbon trading policy.

Previous studies mainly focus on the game analysis of green building development under carbon tax policy, while carbon trading, as one of the important means to promote low-carbon development, is rarely mentioned in promoting the development of the green building market. Based on this, to study the impact of carbon trading policy on the development of the green building market, this study combines prospect theory for carbon trading to build a three-way evolutionary game model of developer-government-consumer. It studies the influencing causes of green building market development under the carbon trading mechanism from the whole perspective. The study shows the existence of a carbon trading policy helps the development of the green building market. In the presence of a carbon trading market, the government's punishment, subsidies, and the setting of carbon prices influence the development of the green building market. In addition, the percentage of carbon emissions bought, the potential benefits, and the selling price also affect the chance of consumers buying green buildings to a greater or lesser extent. This study introduces prospect theory into the developer-government-consumer three-way evolutionary game model, which enriches the research perspective of each subject's behavior in the green building market. It provides theoretical support for developers, governments, and consumers to collaborate to promote the coordination and development of the green building market. It has policy implications for promoting the green and high-quality development of the construction industry.

Clinical Features of COVID-19 in a Young Man with Massive Cerebral Hemorrhage-Case Report.

COVID-19 is currently a pandemic in the world, can invade multiple systems, and has a high morbidity and mortality. So far, no cases of acute cerebrovascular disease have been reported. This article reports the clinical features of a COVID-19 patient whose first symptom was cerebral hemorrhage. More importantly, after the craniotomy, the patient had high fever and it was difficult to retreat. After cerebrospinal fluid testing, it was determined that an intracranial infection had occurred. After anti-infection and plasma infusion of the recovered person, the patient's symptoms gradually improved. This case suggests that COVID-19 may infringe on cerebral blood vessels and cause cerebral hemorrhage. Transfusion of plasma from rehabilitation patients is effective for critically ill patients.

Effects of Mitophagy on Regulatory T Cell Function in Patients With Myasthenia Gravis.

Objective: This study was conducted to determine whether regulatory T cells (CD4+CD25+T, Tregs) show abnormal mitophagy as well as the function of Tregs in patients with myasthenia gravis (MG). Methods: CD4+T cells and CD4+CD25+Treg cells were obtained from 15 patients with MG (MG group) and 15 controls (N group). Tregs from the MG group were subjected to rapamycin-induced culture for 48 h (Rapa group) and 3-methyladenine-induced culture for 48 h (3-MA group). The levels of mitophagy in Tregs were then observed through electron and confocal microscopy. Expression of the autophagy-related protein LC3-II was detected by western blotting, and mitochondrial function in each group was evaluated by flow cytometry. Inhibition of Treg cell proliferation was detected by flow cytometry. Results: Mitophagy in the MG group was lower than that in the N group; it was higher in the Rapa group compared to that in the MG group and lowered in the 3-MA group than in the MG group. Expression of the autophagy-related protein LC3-II was lower in the MG group than in the N group, higher in the Rapa group than in the MG group, and lower in the 3-MA group than in the MG group. The mitochondrial membrane potential was lower in the MG group compared to that in the N group; it was higher in the Rapa group than in the MG group and lowered in the 3-MA group than in the MG group. Inhibition of Treg proliferation was lower in the MG group than in the N group; it was higher in the Rapa group than in the MG group and lowered in the 3-MA group than in the MG group. Conclusion: The decreased mitochondrial membrane potential and mitophagy in Tregs in the MG group may be related to a decreased inhibition of Treg proliferation. The mitochondrial membrane potential was increased after adding the autophagy agent Rapa to enhance mitophagy, and the proliferation inhibition function of Tregs was also enhanced. The autophagy agent 3-MA down-regulated mitophagy, which decreased the mitochondrial membrane potential and inhibitory effect of Tregs. These results reveal the possible cellular immune mechanism of Treg dysfunction in MG.
