[Survey of prevention knowledge and behavior of echinococcosis and influencing factors in residents in agricultural and pastoral areas of Maerkang City].

Objective: To master the prevention knowledge and behavior of echinococcosis and the influencing factors in residents in agricultural and pastoral areas of Maerkang City, so as to provide the reference for formulating the policy and strategy of echinococcosis prevention and control.

Methods: In April, 2017, 796 residents in agricultural and pastoral areas of Maerkang City were selected by the multi-stage stratified random sampling method, and surveyed with questionnaires. The main questions included the prevention knowledge and related behaviors of echinococcosis.

Decreased expression of long non-coding RNA MEG3 acts as a potential predictor biomarker in progression and poor prognosis of osteosarcoma.

Introduction: Long non-coding RNA MEG3 (lncRNA MEG3) has been showed to involve in a variety of cancers. However, the association between lncRNA MEG3 expression level and the prognosis of osteosarcoma is still unclear.

Methods: The expression levels of lncRNA MEG3 in osteosarcoma tissues and adjacent non-tumor tissues were detected using quantitative real-time PCR (qRT-PCR).

Perinatal stress effects on later anxiety and hormone secretion in male mandarin voles.

The estradiol (E2), estrogen receptor-α (ERα), testosterone (T), and androgen receptor (AR) can contribute to anxiety, but whether they are associated with the reversion of prenatal adverse outcomes remains unclear. Here, we tested the interactive effects of prenatal maternal restraint stress and early postnatal short-term maternal separation on adult male mandarin vole (Microtus mandarinus) behavior and changes in E2, T, and their receptors. The results showed that PS adult males (PS/NH) exhibited an increase in anxiety-like behavior in open-field and elevated plus-maze tests than the other 3 groups, including adult male offspring controls (PC/NH), adult male offspring controls with short-term maternal separation (PC/H), and PS adult males with short-term maternal separation (PS/H).

[Properties comparing and evolutionary analysis of MEF2 of Homo sapiens based on bioinformatic methods].

As one of the members of MADS family, MEF2 group is important in regulating development. Analytical tools of NCBI, ExPASy, CBS, CDD, and SABLE were adopted to analyze the properties of human MEF2 proteins, and evolutionary tree was built according to the result of correlative sequence alignments. The results showed that there are various forms of MEF2 in human body, and there are some differences in the physicochemical characteristics.
