Let-7 is found to be downregulated in lung cancer while many kinds of oncogenes expression always increase, and restoration of the let-7 to normal expression level inhibits lung cancer growth evidently.Thus, let-7 might serves as good targets or effective interference tools in exploration of anticancer therapeutics,and has a good prospect in applying it in the early diagnosis, prognosis and therapy in lung cancer.

Objective To study the use on curative effect of Chinese medicine Qingyitang in severe acute pancreatitis.Methods 132 cases of severe acute pancreatitis were randomly divided into 2 groups,The control group(n=62) and the treatment group(n=70).Routine treatment were given in both,otherwise,the Chinese medicine Qingyitang was used in the treatment group.The operation rate,the infection rate,the time of abdominal distension removing and fasting and being hospitalized were observed and compared between two groups.Results Every index of the treatment group was finer than the control group.Conclusions The Chinese medicine Qingyitang showes their protective effects on gut barrier function by alleviating the damage of intestinal mucosa and microecologic disturbance following acute pancreatitis.As a result,the chances of bacterial translocation and enterogenic infection declines.These preparation might raise the treatment effects,as a well,shorten the course of treatment.

Objective To study the expression of p27 gene in endometrial carcinoma and its clinical significance.Methods By using streptavidin-biotin peroxidase(SP) method the expression of p27 gene were examined in 20 normal endometrial tissues and 65 endometrial carcinoma tissues.Results p27 was expressed in 33 of 65(51%) cases of endometrial carcinomas.In contrast,p27 was all expressed in normal endometrial tissues.The expression of p27 was related to the pathological grades,clinical stages and depth of myometrial invasions.Conclusion The level of p27 expression is closely related to the growth,invasion and differentiation of endometrial carcinoma.

Mitochondria are important intracellular energy supply organelles .As semi-autonomous organelles , the mitochondrial biogenesis , damage and clearance were the dynamic processes , which are dual-regulated by mitochondrial genes and nuclear genes , and maintain mitochondrial homeostasis according to the needs of the cells for energy .Recent studies provide evidence that the disorder of mitochondrial biogenesis in the neurons participates in the pathological process after cerebral ischemia/reperfusion, resulting in metabolic disturbance and cell apoptosis .This paper reviews the research progress of mitochondrion and cerebral ischemia/reperfusion injury .

Objective:To investigate levels of serum IL-34 in SLE patients,and correlation between concentrations of serum IL-34 and other established serum markers and disease activity indexes.Methods: In all,78 SLE patients and 53 healthy controls were enrolled in the research.Enzyme-linked immunosorbent assay(ELISA) was employed to measuring the concentrations of serological IL-34.Then,serum IL-34 levels between SLE group and healthy controls were analyzed by Mann-Whitney U test.Meanwhile,the correlation between the serum IL-34 levels and disease activity indexes and other established serum markers were assessed.Serum IL-34 levels were significantly higher in SLE patients compared to healthy controls[(Median,128.9 pg/ml) vs (Median,52.4 pg/ml),P<0.001].Results: Their levels were remarkably associated with accumulation of the clinical features of SLE.Additionally,IL-34 titers were positively correlated with the SLE disease activity indexes,anti-double stranded DNA antibody(anti-dsDNA)titers and C-reactive protein(CRP)levels,but inversely with C3 levels.Conclusion: Serum IL-34 could be a candidate biomarker for SLE as the elevated serum levels in treatment-naive SLE patients and its association with SLE disease activity.

The adhesion molecules expressed by brain microvascular endothelial cell maintain the structure and function of brain, ensure the continuity of endothelium cell and penetrate blood-brain barrier in physiology. They also intervene inflammation cells that remove or orientate regular or inflammation organism in pathology. The adhesion molecules of Immunoglobulin supperfamily and Selectin family are expressed by brain microvascular endothelial cell and have affinity with the ischemic brain damage. The advance in research on relationship between the expression of adhesion molecules by brain microvascular endothelial cell and ischemic brain damage is reviewed in this article.

0.05). The absorbance value of Trichinella-infected muscle conserved at -20 ℃ for 10 wk decreased to 0.43, with significant difference from that conserved at -20 ℃ for 1 wk, but the positive rate was also 100%, and antibodies were detected in all muscle samples conserved at -20 ℃ for 20 weeks when the experiment was ended. Conclusion When animals died or were slaughtered and serum samples could not be collected, muscle juice can be collected from fresh, cool and frozen meat and used as a substitute sample for detecting anti-Trichinella antibodies.

Objective To investigate the correlation between non-lacunar infarcts in the white matter of brain and intracranial or extracranial vessels stenosis.Methods Brain magnetic resonance imaging(MRI) and digital subtraction angiography(DSA) were performed in 30 patients with non-lacunar infarcts in the white matter of brain and the results were analyzed.Results Of 12 cases with focal non-lacunar infarcts in the area of basal ganglion,9 cases were shown occlusion or highly stenosis of proximal segments of unilateral internal carotid artery(ICA) in DSA,2 cases were shown highly stenosis of M1 segment of middle cerebral artery(MCA),and 1 case was normal.Of 6 cases with focal non-lacunar infarcts in the area of basal ganglion and lateral periventricular white matter,3 cases were shown occlusion or highly stenosis of proximal segments of unilateral ICA in DSA,1 case was shown occlusion of C5 segment of unilateral ICA,and 2 cases were shown occlusion of M1 segments of MCA.Of 4 cases with focal non-lacunar infarcts in periventricular white matter or centrum ovale,1 case was shown occlusion of C5 segment of unilateral ICA,2 cases were shown highly stenosis of M1 segments of MCA,and the other one was normal.Of 8 cases with subcortical superior border infarction(SSBI) or subcortical lateral border infarction(SLBI),6 cases were shown occlusion or highly stenosis of proximal segments of unilateral ICA,1 case was shown occlusion of proximal segments of bilateral ICA,and 1 case was shown occlusion of M1 segment of MCA.Conclusion There are strong correlations between focal non-lacunar infarcts in the areas of basal ganglion or lateral periventricular white matter and the stenosis or occlusion of large arteries of ICA system.
