Congenital heart disease(CHD) is one of the most common birth defects,which is caused by either hereditary or environmental factors,and more commonly by the combination of both.Although CHD is known to be a polygenetic disease,its molecular pathogenesis is still poorly understood.Many genes including the transcription factors have recently been identified to be involved in the development of heart as well as in the pathogenesis of CHD.At the molecular level,this paper reviews the roles of the transcription factors of GATA4/5/6,Nkx2.5,Nkx2.7,TBX1,TBX5,and TBX20,and the interactions among them in the abnormal development of the heart.

Severe incomplete cerebral ischemia was induced in 70 rabbits using bilateral carotid artery occIusion coupled with hemorragic hypotension. 60 minutes of ischemia was followed by 2 hours of reperfusion. The electroencephalographic activity, cardiac output and mean artery blood pressure were measured at regular intervals. The activities of lactic dehydrogenase(LDH) and creatine phosphokinase(CPK) in cerebral venous blood were measured before and after the insult. The contents of water, sodium, potassium and cyclic uncleotides were determined in cerebral cortex after 60 min of ischemia and 120 min of reperfusion respectively. The histological and ultrastructural alterations were observed. The results indicate that the acute incomplete cerebral ischemie model in the rabbit can be successfully established by hypotension plus hypoperfusion. Its characteristics are severe suppression of electroencephalographic activity, significant eIevation of LDH and CPK, an increase in the contents of water and sodium. Ischemic edema was demonstrated morphologically in cerebral cortex. During the reperfusion peroid, initially some recovery of the electroencephaiographic activity appeared but then severe suppression occurred; the severety of brain edema was exacerbated; the content of cAMP was increased further and the activities of LDH and CPK were still significantly elevated. Severe ischemic tissue damage in cerebral cortex were morphologically demonstrated, of which the ultrastructural alterations were more remarkable. These results suggested that the ischemic tissue damage might be aggravated on reperfusion. The possible mechanisms were discussed. The cerebral circulatory disturbance and parenchymal insult during reperfusion peroid might play an important role in developing the irreversible postischemic brain damage.

Colorectal cancer( CRC) is one of the most common tumor,which has complicated pathogene-sis.it is estimated that the vast majority of CRCs is non-hereditarysporadic cancerswith no apparent evidence of an inherited component.Sporadic CRC results from the cumulative effects of multiple genetic and epigenetic al-terations caused by somatic mutations, which may be the indirect result of several environmental factors them-selves.There are at least 3 major genetic alternations that lead to colorectal carcinogenesis:(1)The chromosomal instability(CIN)pathway;(2)The microsatellite instability(MSI)pathway;(3)The cytosine-phospho-guanine ( CpG) island methylator phenotype( CIMP) pathway,while DNA methylation,modifications in histone proteins and microRNAs( miRNAs) are analyzed in the field of epigenetic alterations.This review summarizes the newest bio-molecular progression involved in CRC pathogenesis,for the purpose of improving strategy for prevention,surveil-lance,early diagnosis and therapy.

Acute myeloid leukemia (AML) is a group of heterogeneous malignant diseases inhematological system, with significant differences in morphology, immunology, genetics, molecular biology and clinical manifestations. Cytogenetics detection has become one of the main bases for the accurate diagnosis, treatment options and prognosis judgement of AML. However, the high heterogeneity at the molecular level leads to low detection rate by conventional cytogenetics detection technology. Clonal chromosome aberrations in 40 %ˉ50 % of patients with AML could not be detected by using standard chromosomal banding, which might be called normal karyotype AML (NK-AML). The common molecular genetic changes in non-M3 AML includes FLT3, NPM1, DNMT3A and IDH mutations. This paper mainly reviews the characteristics of the above four genes, pathogenesis and prognosis of non-M3 AML.
