In the traditional power system demand response, customers respond to electricity price or incentive and change their original power consumption pattern accordingly to gain additional benefits. With the development of multi-energy systems (MES) in which electricity, heat, natural gas and other forms of energy are coupled with each other, all types of energy customers are able to participate in demand response, leading to the concept of integrated demand response (IDR). In IDR, energy consumers can response not only by reducing energy consumption or opting for off-peak energy consumption but also by changing the type of the consumed energy. Taking the traditional demand response in power system as a starting point, the studies of the fundamental theory, framework design and potential estimation of demand response in power system are reviewed, and the practical cases and software development of demand response are introduced. Finally, the current theoretical research and application of IDR are assessed.

Enhancer of zeste homolog 2(EZH2),an epigenetic regulator that inhibits transcription primarily through trimethylation of Lys-27 in histone 3(H3K27me3),has been reported to play an important role in the regulation of cell cycle,autophagy,and apoptosis,and DNA damage repair.1 EZH2 is highly expressed in a variety of cancers including prostate cancer,breast cancer,and renal clear cell carcinoma,and is associated with adverse prognosis.1 Moreover,it has been reported that EZH2 might increase tumor stemness and metastasis capacity and inhibit antitumor immunity by affecting T cells,NK cells,macrophages,and immune checkpoints.2,3 However,the prognostic value and the mechanism of EZH2 have not been investigated in *** this study,RNA sequencing and whole genome sequencing data based on 48 skull base chordomas as well as immunohistochemistry of paraffin sections were analyzed to elucidate the role of EZH2 in skull base *** found copy number gain mediated high EZH2 expression is associated with tumor stemness,M2 macrophage infiltration,and adverse prognosis in ***,we demonstrated that EZH2 promotes the proliferation,migration,and invasion of chordoma cells in in vitro cell experiments.
