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 .

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.

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.

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.

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.

Objective: To investigate the effect of combined acupuncture and rehabilitation on intelligence and motor development of high risk infants with perinatal brain injuries. Methods: Ninety-seven survived cases in the neonatal intensive care unit (NICU) were allocated into a treatment group of 53 cases and a control group of 44 cases following the consent of the parents. Cases in the treatment group were treated by combined acupuncture and rehabilitation; whereas cases in the control group were treated by conventional child care methods. Systemic follow-up has been made for 2 years. Then the infants' intelligence was evaluated respectively in the 6th, 12th and 34th months. Results: Compared with the control group, the mental development indexes (MDI) and physical development indexes (PDI) in the treatment group were increased by 14.96 and 9.82 respectively. There was a significant difference (X2=8.1659, P<0.01) in the abnormal intelligence rates between the treatment group (15.1%) and the control group (40.9%,). Conclusion: Combined acupuncture and rehabilitation can effectively improve the mental and physical development of high-risk infants with perinatal brain injuries. Additionally, this therapy can decrease the disability rates and increase the infants' quality of life.
