ABSTRACT
Insomnia is the second most common psychiatric disorder in clinical practice, and more than one-third of adults may experience different forms of insomnia during their lifetime, but the root causes behind insomnia need further clarification. Early evidences from twins and family studies had shown that insomnia can be attributed to genetics. In recent years, with the rapid development of gene sequencing technology, Nature Genetics had published several consecutive articles focusing on insomnia and genes, confirming that genetic factors played an important role in the occurrence and development of insomnia. Therefore, the recent research progresses on insomnia and circadian rhythm, cytokines, neurotransmitters, and other related genes were summarized in this review, which could help to understand the pathogenesis of insomnia and develop precise treatment strategies.
ABSTRACT
OBJECTIVE To study characteristics of changing T lymphocytes in epidemic hemorrhagic fever(EHF) patients during acute phase and find out the pathogenesis,in order to elevate the level of early diagnosis.METHODS The anticoagulant blood from 30 cases of EHF patients and 50 normal healthy blood donors was collected.T lymphocyte subsets were detected by flow cytometry.RESULTS Compared with those of normal persons,CD4+ T cell counts of EHF patients decreased,CD8+T cell and double CD4+CD8+ cell(double positive cells,DP cell) counts of EHF patients increased obviously,and 25 cases of EHF in recovery stage returned to normal.And in comparison with HIV,CMV and EBV patients,DP cell counts of EHF patients increased obviously.CONCLUSIONS T lymphocytes of EHF decrease obviously but could be resumed,detection of amounts of lymphocyte subsets and CD4+CD8+ cells can provide an early diagnosis method to EHF.
