Our study focused on investigating the bioeffects of extremely low-frequency electromagnetic fields (ELF-EMFs) on the immune function of the spleen. We designed an electromagnetic instrument that can locally target on spleen, the spleens of mice were locally exposed to the ELF-EMF (50 Hz, 30 mT) for 14 days (4 h/day). Parallelly, the isolated splenic T cells were exposed to ELF-EMF (50 Hz, 15 mT) for 2 h.

Methods: Data were obtained from the TCGA and ICGC databases, and the intersection with mitochondrial genes was used to obtain the differentially expressed genes. q-PCR, Cox proportional risk regression, minimal absolute contraction and selection operator regression analysis were performed to construct the prognostic risk model, and ROC curve was used to evaluate the model for centralized verification.
The establishment of the China Pilot Free Trade Zone complies with the concept of sustainable development, and its construction can not only realize trade liberalization and facilitation but also activate the green innovation momentum of enterprises to help solve China's current dilemma of sustainable development and economic growth. This paper is the first to consider the impact of the establishment of the pilot free trade zone from the perspective of enterprise green innovation efficiency, providing a direct answer to the key question of whether the construction of the pilot free trade zone can truly serve the high-quality development of the economy in the new era, and enriching the theoretical research on the enterprise green innovation efficiency macro-drivers related theoretical research. In addition, this paper uses the super-efficient EBM-GML model to measure the level of green innovation efficiency of enterprises, on the basis of this, it adopts the multi-stage differences-in-differences method used to evaluate the impact of the establishment of the pilot free trade zone on the green innovation efficiency of enterprises.

The spleen serves as an extra monocyte reservoir in inflammatory conditions; however, the precise mechanisms of involvement of the spleen in the pathogenesis of liver fibrosis remain unclear.
Approach And Results: By splenectomy and splenocyte transfusion, it was observed that splenic CD11b + cells accumulated intrahepatically as Ly6C lo MoMFs to exacerbate CCl 4 -induced liver fibrosis.
Tumor-derived extracellular vesicles (EVs) promote ovarian cancer (OC) metastasis by carrying microRNAs (miRs). This study investigated the mechanism of miR-106a-5p carried by OC cell-derived EVs in OC. miR-106a-5p expression in OC tissues and cells was measured.

Purpose: The 12q terminal duplication is a chromosomal structural abnormality that has been rarely reported. The common clinical manifestations include intellectual disability and speech delay. We report two cases of patients with a duplication of chromosome 12q which was discovered incidentally during non-invasive prenatal genetic testing (NIPT).

However, the role of COX7RP, a critical regulator in the formation of mitochondrial respiratory supercomplex that has been suggested to be over-expressed in hepatocellular carcinoma (HCC) by our bioinformatic analysis of TCGA data, in tumor progression remains largely unclear. In this study, we found that COX7RP is frequently over-expressed in HCC mainly due to the down-regulation of miR-130a-3p and predicts poor prognosis of HCC patients.

Objective: To generate a new strain of HBeAg transgenic mice using CRISPR/Cas9 technique.
Methods: Hepatitis B virus (HBV) HBeAg gene was cloned and inserted in the pliver-HBeAg expression frame at the site of Rosa26 gene using CRISPR/Cas9 and homologous recombination techniques to construct the pliver-HBeAg expression vector containing HBeAg gene. The linear DNA fragment containing HBeAg gene was obtained by enzyme digestion.
