CgmiR307 involved in the regulation of Nrf2-dependent oxidative response in the Pacific oyster Crassostrea gigas under high-temperature stress.

miRNA, a type of endogenous small non-coding RNA, is involved in the response to various environmental stresses through post-transcriptional regulation. In the present study, the role of CgmiR307 in the regulation of oxidative response under high-temperature stress by targeting CgNrf2 was investigated in the Pacific oyster Crassostrea gigas. The binding site of CgmiR307 were predicted at 1799-1818 bp in the 3'-UTR of CgNrf2, and the binding activity of CgmiR307 with the mRNA of CgNrf2 was further proved by the dual-luciferase reporter assay.

The expression patterns of exosomal miRNAs in the Pacific oyster after high-temperature stress or Vibrio stimulation.

The exosomal miRNA plays a crucial role in the intercellular communication response to environmental stress and pathogenic stimulation. In the present study, the expression of exosomal miRNAs in the Pacific oyster Crassostrea gigas after high-temperature stress or Vibrio splendidus stimulation was investigated through high-throughput sequencing. The exosomes were identified to be teardrop-like vesicles with the average size of 81.

Tibetan medicine Si-Wei-Qiang-Wei Powder ameliorates cholecystitis via inhibiting the production of pro-inflammatory cytokines and regulating the MAPK signaling pathway.

Ethnopharmacological Relevance: Si-Wei-Qiang-Wei Powder (SWQ) is a formulated traditional Tibetan medicine preparation that has been used clinically to treat liver and gallbladder diseases for centuries. Previous work has confirmed its clinical effectiveness, however, the specific mechanism of SWQ is still unknown.

Aim Of The Study: This study aims to explore the anti-inflammatory effect of SWQ on cholecystitis and its possible mechanism.

[Serologic characteristics and population distribution of subtypes B2 and AB2 of ABO blood group].

This study was aimed to investigate the serologic characteristics, genetic background and population distribution of B2 and AB2 subtype in Chinese ABO blood group. The classic blood group serological technology was used to detect ABO blood group of the propositus and their family members, the anti-B1 serum prepared by yourself was used to investigate the distribution of B1/B2 and AB1/AB2 subtype of the blood donor. The results indicated that the antigen of propositus was AB2 subtype and that of his child was B2 subtype.
