Minimal residual disease (MRD) is the cause of relapse in leukemia,and its dynamic monitoring has been a hotspot yet proven to be difficult.MRD in acute B-lineage lymphoblastic leukemia has its own characteristics,normal bone marrow produces a large number of B precursor cells,easily mistaken for leukemia cells,and there were no specific gene alterations that can be conveniently detected.This paper summarizes the antibody combinations in flow cytometry,timing for surveillance and polymerase chain reaction for gene detection,and provide a reference for B lymphocytic leukemia MRD monitoring.

Objective To detect the effect of insulin-like growth factor-1 (IGF-1) at varied levels in pregnancy maternal serum and cord serum of patients with the polycystic ovary syndrome (PCOS) on pregnancy outcomes, and explore whether IGF-1 could be used as a diagnostic marker for PCOS. Methods From January 2012 to December 2013, pregnancy maternal and cord serums were collected from 120 PCOS patients and 120 normal pregnant women in the Department of Obstetrics and Gynecology of our hospital. ELISA was used to detect the levels of IGF-1, and analyze the levels of IGF-1 in different pregnancy outcomes between normal pregnant women and PCOS patients. Results Compared with the control group, the levels of IGF-1 in pregnancy maternal and cord blood were increased significantly in patients with PCOS (P< 0.05). The incidence of stillbirth, premature delivery and macrosomia was significantly higher in PCOS patients. The levels of IGF-1 in pregnancy maternal and cord serum were significantly higher in all PCOS patients with adverse pregnancy outcomes compared with the control group (P < 0.05). Conclusion IGF-1 could be used as a risk prediction marker for pregnancy outcome in patients with PCOS.

Apolipoprotein M-sphingosine-1-phosphate axis ( apoM-S1P axis ) signaling pathway consists of apolipoproteinM (apoM), sphingosine-1-phosphate (S1P) and sphingosine-1-phosphate receptor (S1PR).Plasma apoM belongs to lipocalinsuperfamily members , and is mainly associated to high density lipoprotein( HDL), whereas HDL-cholesterol correlates inversely with cardiovascular risk .The ability of apoM to bind S1P is due to a lipophilic binding pocket within the lipocalin structure of the apoM molecule . S1P, a bioactive mediator of phospholipid metabolism , predominantly abound in HDL among all lipoproteins.S1P can not only be used as intracellular second messengers , but also as intercellular signal molecules, activating of G protein-coupled receptors (S1PR) to mediate various physiological functions.It′s clear that apoM protects human beings from atherosclerosis .Furthermore, recent studies showed that S1P has a significant impact on atherosclerosis , and ApoM-S1P axis may play a important role in the pathogenesis or progression of atherosclerosis .

C-fos,one of the immediate-early genes,encodes Fos,which appears to modulate the express of more “downstream” genes and attribute to long-term changes in cellular function.Recently,c-fos has been researched on extensively and progress has been acquired greatly.This article summarizes c-fos on structure,function and the relationship to epilepsy.

PRDI-BFI and RIZ homology domain containing proteins (PRDM) play a key role in cell differentiation and proliferation.Most members of the PRDM gene family are tumor suppressor genes which involved in tumorigenesis and abnormal expression in a variety of tumors.Aberrant DNA methylation often silences these genes,which may occur in the early stage of tumor,Cancer can be reversed by demethylation,which provides a new way for cancer treatment.

As an internal environment of tumor occurrence, tumor microenvironment is composed of a variety of cells and extracellular matrix, and plays a crucial role in tumor formation, transfer and resistance to drugs. The regulation of tumor microenvironment will be a potential target to control the cancer. MicroRNAs (miRNAs) are a kind of 21 to 25 nucleotides single-stranded RNA, and are mainly involved in regulating gene expression. Recently, with the suggestion of cellular auton-omous tumor inhibition mechanism, the regulation of tumor microenvironment by miRNAs has received great attention. This review summarizes recent findings on the non-cell-autonomous mechanisms of miRNAs-mediated regulation of tumor micro-environments, which provides foundations and perspective on the design of therapeutic interventions.

Glioblastoma (GBM) is one of the WHO gradeⅣmalignancies, which is an acentral nervous system cancer with poor prognosis unless the lesion is in the brain stem. The incidence of GBM accounts for 80%of human primary malignant tumors in brain. Only 5%GBM can survive up to 5-years. Many researches showed that Sox2 is a pluripotent regulator, and muta?tion or abnormal function of Sox2 are closely related to the development of GBM. There are studies demonstrated the possibil?ity of using Sox2 gene as apotential target for GBM therapy. This paper reviewed recent progress in GBM.

Objective To investigate the mechanisms of Chinese traditional medicine mixture protection of vascular endothelial cell from apoptosis in cerebral ischemia-reperfusion injury. Methods Healthy, clean SD rats were randomly divided into 4 groups: Sham opera-tion group (SOG), cerebral ischemia reperfusion injury group (IRG), cerebral ischemia preconditioning group (IPG) and Chinese tradi-tional medicine mixture preconditioning group (CPG). Furthermore, IRG, IPG and NPC were divided into 4 sub-groups: 1 d, 7d, 14d, 21d subgroup, according to the different time point since ischemia-reperfusion took place. And in CPG, Naotai formula extract was used. Cere-bral vascular endothelial cells of rats were removed and Hoechst 33258 staining and the DNA gradient bands were used to detect the apoptosis of these cells. Then the influence of Naotai formula extract on caspase-3, 8 and 9 activation, and Bid lysis was examined by Western-blot, and the mechanisms of Chinese traditional medicine mixture protection of vascular endothelial cell were investigated from apoptosis signal pathway. Result Naotai formula extract can inhibit the apoptosis of endothelial cells in ischemia-reperfusion injury, and it also can inhibit the activation of caspase-3, 8 and 9, thus inhibit the lysis of Bid into tBid. Conclusion Naomi formula extract inhibit the apoptosis of endo-thelial ceils in ischemia-reperfusion injury via apoptosis signal pathway.

Objective To explore the clinical effect of health education and psychological nursing intervention on the prognosis of patients with postpartum depression. Methods Ninety cases of postpartum depression in our hospital from March 2012 to March 2014, were randomly divided into the control group and the observation group, 45 cases in each group. The patients in the control group were given routine nursing, the patients in the observation group received health education and psychological intervention on the basis of the control group. The anxiety and depression scores change, medication adherence and quality of life in the two groups were observed and compared. Results The scores of SDS and SAS in the observation group were significantly lower than those in the control group (P<0.05) . The medication adherence and quality of life score 3 months and 6 months after discharge in the observation group were significantly higher than those of control group (P<0.05) . Conclusion Health education and psychological intervention has positive effect on the prognosis of postpartum depression patients, and can effectively improve the patient's medication compliance and quality of life, it's one of the effective measures for the prevention and treatment of postpartum depression.
