Exploring the relationship between red blood cell levels and emotional regulation through the miR191-Riok3-Mxi1 pathway

Objective:To assess emotional fluctuations,physical and mental health status,and indicators closely related to red blood cells,such as RIO kinase 3(Riok3),MAX interactor 1(Mxi1),and microRNA 191(miR191),in participants with different levels of red blood cells.Methods:Participants who underwent physical examinations at Dongfang Hospital between April and October 2019 were divided into healthy,blood deficiency,and anemia groups(30 individuals in the healthy and blood deficiency group respectively,and 13 in the anemia group).The physical and mental conditions of the participants were evaluated through questionnaires,and emotional fluctuations were assessed through an emotion-inducing experiment,in which participants watched video segments designed to induce specific emotions.Relative expression levels of miR191,Riok3,and Mxi1 from venous blood samples were also determined.Results:The main psychological factors identified in the anemia and blood deficiency groups were obsessive-compulsive symptoms,depression,anxiety,and other negative emotions.Relative gene expression levels indicated that miR191 was upregulated and Riok3 and Mxi1 were downregulated in both the blood deficiency and anemia groups.Regarding the emotional score of disgust on video stage,the main effect was significant(F=335.58,P<.001),which showed that watching the three videos caused participants to have a dominant emotion,and there is a difference on group(F=5.35,P=.01),with higher disgust scores in the anemia and blood deficiency groups.The symptoms of blood deficiency and anemia,such as weakness in limbs were significantly negatively correlated with Riok3 and Mxi1 expression(r=-0.38 and-0.31 respectively),but was significantly positively correlated with miR191 expression(r=0.29).Conclusion:We determined that a close relationship exists between red blood cell levels and emotional status.Our findings suggest that individuals with anemia and blood deficiency are more likely to experience psychological problems and negative emotions,particularly disgust.We also demonstrate that emotional regulation is related to mir191-Riok3-Mxi1 pathway activity,identifying these pathway components are potential targets for genetic therapies in combination with psychological therapy.

A Serological Survey of Contagious Caprine Pleuropneumonia in Taizhou City,Jiangsu Province

[ Objective] This study aimed to investigate the prevalence of contagious caprine pleuropneumonia in Taizhou City, Jiangsu Province. [ Method] By using indirect hemagglutination assay kits for detection of antibodies against Mycoplasma capricolum subsp, capripneumoniae （ Mecp）, Mycoplasma mycoides subsp. capriclonum （Mmc） and Mycopalsam ovipneumonia （ Movi）, 1 157 goat sera from Taizhou City of Jiangsu Province were detected. [ Result ] The average positive detection rate of Mccp and Mmc in infected goats was 51.85% and 39.81%, respectively; the average positive detection rate of Mccp and Mmc in non-infected goats was 10.52% and 5.84%, respectively, and the total positive detection rate of Mycoplasma infections was 16.37%. [ Conclusion ] Mycoplasma infections oc- cur commonly in Taizhou City. The prevention and control of Mycoplasma infections should be strengthened.
