To study the expression of both Fos and HSP70 proteins in the early stage of acute myocardial ischemia/reperfusion(I/R) in rats with immunohistochemistry in order to search the objective morphologic evidence for the forensic pathological diagnosis.I/R rat model was established by ligation of the anterior branch of the left coronary artery.All animals were divided into 7 groups.Tissues were cut and stained immunohistochemistry with the corresponding anti Fos and anti HSP70 sera as the first antibodies.There was no expression of both Fos and HSP70 proteins in control group.The expression of HSP70 protein began to increase in myocytes 1h after I/R in the ischemic areas and increased gradually wtih the prolongation of ischemia,while it began to express 2h after I/R in the non ischemic areas.Fos protein began to express 0 5h after I/R in the ischemic areas,1h in the non ischemic areas.The expressions of both HSP70 and Fos proteins in the non ischemic areas were weaker than those in the ischemic areas.Meanwhile,the expression of HSP70 and Fos proteins appears firstly in the inner layer of myocardium and extended gradually toward the outer layer.The expression of Fos protein mainly located in the inner layer of myocardium 0 5h after I/R and then extened to the whole layer of myocardium 1h after I/R.The expression of Fos protein in outer layer was stronger than that in inner layer at 4h after I/R.The expression of HSP70 protein located mainly in the inner layer of the myocardium at 1h and 2h after I/R,and then extended to the whole layer of the myocardium at 4h and 6h after I/R.The results indicated that the I/R induced the expression of both HSP70 and Fos proteins in the early stages of myocardial ischemia.The location and the intersity of the immunoreactivity of these two proteins changed at the different stages after I/R.These changes observed in the present study might be useful for the forensic pathological diagnosis of the early myocardial ischemia.

Noninvasive early diagnosis of colorectal cancer is conducive for patients to reduce the mortality rate and their suffering from diagnosis procedures.One of the most significant methods to proceed noninvasive early diagnosis of colorectal cancer is analysis of stool DNA.Extracting high quality and great quantity of human genomic DNA from stools guarantees diagnosis accuracy.However,the complexity of stool component hinders DNA extraction.Hence,it is crucial to develop highly efficient extraction methods of human genomic DNA from stools for the DNA analysis-based early diagnosis of colorectal cancer.Currently,two kinds of extraction strategies are employed:one is to directly extract total DNA from stools,the other is to enrich exfoliated colonocytes in stools before DNA extraction.This article reviews the advances on these two kinds of extraction techniques and summarizes their applications.

Objectives To analyze the risk factors associated with infant wheezing in Zhongshan city. Methods A multi-center, large sample of case-control study was applied and the data related to risk factors was collected by questionnaire survey. T test and chi-square test were firstly used for univariate analysis, and then the multivariate stepwise logistic regression was used to analyze the independent risk factors associated with infant wheezing. Results A total of nine factors were found rele-vant to infant wheezing by univariate analysis including parental allergic history, way of birth, respiratory syncytial virus infec-tion, Mycoplasma pneumoniae infection, personal allergic history, like crying, parents have constant disagreements, home near the road, and factory around (P<0.05). Parental allergic history (OR=3.441, 95%CI:1.914-6.186, P<0.001), respiratory syncy-tial virus infection (OR=2.910, 95%CI:1.793-4.723, P<0.001), Mycoplasma pneumoniae infection (OR=2.277,95%CI:1.110-4.667, P=0.025), home near the road (OR=2.036, 95%CI:1.280-3.239, P=0.003) and like crying (OR=1.521, 95%CI:1.049-2.206, P=0.027) were approved to be the independent risk factors of infant wheezing in ZhongShan. Conclusions Nine factors have relationship with infant wheezing, including parental allergic history, respiratory syncytial virus infection, Mycoplasma pneumoniae infection, home near the road, like crying, personal allergic history, and that the former five factors are the indepen-dent risk factors.
