On page 1107, line 21, "Definition 4" should be in bold face, in consistency with the previous definitions. Therefore, "Definition 4:" should be "Definition 4:". On page 1108, Figure 1, two sub-figures were reversed. Therefore, the Figure 1 should be changed from: Figure 1. The schematic diagram of iterated elimination of strictly dominant strategies.

The m6A mRNA methylation involves in mRNA splicing, degradation and translation. Recent studies have revealed that reduced m6A mRNA methylation might promote cancer development. However, the role of m6A mRNA methylation in cervical cancer development remains unknown. Therefore, we investigated the role of m6A methylation in cervical cancer in the current study. We first evaluated the m6A mRNA methylation level in 286 pairs of cervical cancer samples and their adjacent normal tissues by dot blot assay. Then the role of m6A on patient survival rates and cervical cancer progression were assessed. The m6A level was significantly reduced in the cervical cancer when comparing with the adjacent normal tissue. The m6A level reduction was significantly correlated with the FIGO stage, tumor size, differentiation, lymph invasion and cancer recurrence. It was also shown to be an independent prognostic indicator of disease-free survival and overall survival for patients with cervical cancer. Reducing m6A level via manipulating the m6A regulators expression promoted cervical cancer cell proliferation. And increasing m6A level significantly suppressed tumor development both in vitro and in vivo. Our results showed that the reduced m6A level is tightly associated with cervical cancer development and m6A mRNA methylation might be a potential therapeutic target in cervical cancer.

A very important yet really challenging issue to address is how to greatly increase the energy density of supercapacitors to approach or even exceed those of batteries without sacrificing the power density. Herein we report the fabrication of a new class of ultrahigh surface area hierarchical porous carbon (UHSA-HPC) based on the pore formation and widening of polystyrene-derived HPC by KOH activation, and highlight its superior ability for energy storage in supercapacitors with ionic liquid (IL) as electrolyte. The UHSA-HPC with a surface area of more than 3000 m(2) g(-1) shows an extremely high energy density, i.e., 118 W h kg(-1) at a power density of 100 W kg(-1). This is ascribed to its unique hierarchical nanonetwork structure with a large number of small-sized nanopores for IL storage and an ideal meso-/macroporous network for IL transfer.
