Objective:The early phase of sepsis is dominated by a hyper-inflammatory state which is characterized by production of Pro-inflammatory cytokines. This pro-inflammatory response stage is replaced rapidly by an antiinflammatory response stage which may give rise to an immunosuppressive phase. In light of the important role of Regulatory T cells(Tregs) in immune dysfunction during sepsis, we examined whether Tregs participate in the immune response to secondary *** lung infection during sepsis by using a "second-hit" ***:(1) The expression of Tregs in secondary infection mice model and its relationship with sepsis-induced immunosuppression. C57BL/6 female mice, 6-8 weeks old were obtained from and raised at the Wenzhou Medical University. Animals were submitted to sham or CLP and at 3 d or 7 d post CLP, mice were anesthetized again with mixture of ketamine and xylazine to create a model of "second-hit" pneumonia of sepsis. In brief, 20 ul of a bacterial suspension(4× CFU) was carefully injected through trachea. The mice were sacrificed by anesthesia overdose 24 h after *** or saline intratracheal injection and Broncho-alveolar lavage fluid(BALF) were collected immediately for bacterial culture. The proportion of CD4+CD25+Foxp3+ cells in spleen were analyzed by flow cytometric and lungs were collected for immunohistochemical analyze. Following a "second-hit", the levels of lung tissue cytokines(IL-1β, IL-6, IL-10, IL-17 A) were evaluated with ELISA. The lung tissues of mice undergoing secondary lung infection were stained with H & E and examined with light microscopy.(2) The effect of anti-CD25 mAb(PC61) on sepsis-induced secondary lung infection. To examine whether the Tregs contribute to the sepsis-related secondary acute *** lung infection, PC61(200 μg/mouse, i.p.) was administrated to eliminate the Treg cells in mice. The depletion efficiency of PC61 was evaluated by spleen flow cytometric and lung immunohistochemical analyze. L

CLEAN ENERGY 2024年第2期8卷 89-103页

With the implementation of China's carbon-peaking and carbon-neutrality strategy, new energy will achieve leapfrog growth. Due to the good economics of distributed new-energy generation, it can not only save users' own investment, but also help to achieve local consumption of new energy. However, it will also bring about a series of incremental costs to the power grid. This paper first enumerates the concept, development status and scheduling mode of a distributed new-energy storage system. Based on the above, it establishes a new-energy power generation model and an energy storage system charging and discharging model, and proposes a global optimization scheduling model for a distributed new-energy storage system, considering the time-of-use electricity price and taking the lowest total operating cost of the distributed new-energy power generation system as the objective function. Finally, it proposes a distribution network incremental cost analysis model based on the penetration of distributed new energy. The calculation results show that the incremental cost of grid-connected distributed new energy is 1.0849, 1.2585 and 1.3473 yuan/kWh, respectively, which indicates that the global dispatching model can optimize the power consumption structure of a distributed power generation system, and has the function of peak shaving and valley filling, but the incremental cost of the distribution network will also increase. A new-energy power generation model and an energy storage system charging and discharging model use a global optimization scheduling method, considering the time-of-use electricity price and taking the lowest total operating cost as the objective function. The results show the incremental cost of grid-connected distributed new energy. Graphical Abstract

Deubiquitinases(DUBs)are a class of enzymes that are able to reverse the process of ubiquitination.1 Extensive research has revealed that there are more than 100 DUBs found in humans,which are classified into seven main families:ubiquitin-specific proteases(USPs),ubiquitin carboxyl-terminal hydrolases,the Machado-Joseph disease domain superfamily,the otubain/ovarian tumor-domain containing proteins,the ZUFSP(Zinc finger with UFM1-specific peptidase domain protein)family,the JAB1/MPN/MOV34 proteases,and the novel motif interacting with ubiquitin-containing DUB *** DUBs are cysteine proteases,except the JAB1/MPN/MOV34 proteases,which are Zn^(2+) metalloproteases.
