Epigenetic modification, which involve DNA methylation, RNA-associated silencing and histone modification, is implicated in cell proliferation, differentiation, survival, apoptosis and malignant transformation. Some leukemogenesis has been shown to be aberrance of epigenetic modification. This paper discussed the potential causes of some of leukemias correlating with the methylation of cell cycle regulation genes, small interference RNA and modification abnormality of histone after translation. The study on epigenetic modification abnormality of leukemia cells provides a new strategy for treatment of leukemia.

Posterior circulation iscbemia refers to the transient iscbemic attack and the cerebral infarction in vertebrobasilar artery system,its prognosis is not as good as anterior circulation ischemia,and its treatment is similar to that of anterior circulation ischemia.However,because of the mortality of basilar artery occlusion is higher,usually more aggressive treatment should be considered,such as thromholytic therapy(especially intra-arterial thromholysis)and endovas- cular therapy,and the therapeutic time window is much longer.This article reviews the treatment of anterior circulation ischemia.

Objective]To investigate academic thoughts of Prof. Yan Dexin in spleen and stomach syndrome treatment.[Methods]The paper summarized the academic origin, academic thoughts as well as practical treatment cases of Prof. Yan Dexin ’s spleen and stomach syndrome treatment theory. [Results]The main points of Prof. Yan’s academic thought on spleen and stomach therapy has succeeded and developed the therapy of Menghe physician, which includes an emphasis on spleen Qi rise and stomach Yin drop, Qi of spleen and stomach regulation, special attention on the function of the stomach-yang and spleen-yin, an advocation ofspleen leading four organs, and therapy design from spleen with an ingenious use of atractylodes rhizome, Atractylodes and Zhizhu pill. [Conclusion] Professor Yan Dexin developed his unique theoretical system in spleen-stomach diseases therapy on basis of the experiences of spleen and stomach disease treatment from ancient physicians, which is instructive for later physicians.

Objective:To explore the pathogenesis of abnormal behavior in children with obstructive sleep apnea-hypopnea syndrome(OSAHS).Method:The behavioral problems and C-reactive protein were measured in 40 children with OSAHS and 30 children with habitual snoring who underwent overnight Polysomnography,40 cases of healthy children for the control group.Result:The ratio of abnormal behavior in OSAHS and abitual snoring children was significantly higher than that of the healthy control group,while no significant difference between the two groups.The content of C-reactive protein in OSAHS children(4.24 mg/L)was significantly higher than habitual snoring(2.76mg/L)and healthy control group(1.27mg/L);in habitual snoring children C-reactive protein was higher than in healthy control group.The content of serum C-reactive protein in OSAHS children accompanied by abnormal behavior(4.63 mg/L)was significantly higher than that without abnormal behavior(3.23 mg/L).The content of serum C-reactive protein content in habitual snoring children accompanied y abnormal behavior (3.63 mg/L)was significantly higher than that without abnormal behavior(1.76 mg/L).Conclusion:OSAHS and habitual snoring children have more behavior problems.C-reactive protein levels are higher in children with OSAHS and habitual snoring.and the levels of C-reactive protein are related to the abnormal ehavior in these children.

Sleep plays an important role in the modulation of endocrine function and energy metabolism;hormone levels are markedly different during a sleepless night compared with a night of normal sleep.Sleep deprivation may change the levels of cortisol,growth hormone(GH)and thyrotropin(TSH)at night.In addition,sleep curtailment disturbs the balance of anorexi- genic(leptin)and orexigenic(ghrelin)factors,and does harmful to glucose tolerance.

Objective To study the correlation between chronic gastritis with benign mucosal nodular-change,Helicobacter pylori(H.pylori)infection and lymphoid follicles infiltration.Methods During July 1,2004 to June 30,2005 patients with chronic gastritis and benign mucosal nodular-change were identified by chromo-endoscopy with anabrosis indigo carmine staining at the antrum.Multiple biopsies were obtained for H.pylori detection with quick test and for pathology examination of mucosal lymphoid follicles formation and lymphocyte infiltration,as well as H.pylori infection.Results The patients were divided into nodular gastritis group,atrophy gastritis group and verrucous gastritis group with mean age of(31.00?11.62),(58.61?12.14)and(51.29?12.99)years old,respectively.The patients with nodular gastritis were the youngest(P

Objective: To construct a high effective eukaryotic expre ss ing vector containing mcpr1 gene. Methods: mcpr1 gene w as amplified by PCR from the plasmid T-easy/ mcpr1, then PCR product was in serted into eukaryotic expressing vector pcDNA3.1/V5-His B. The positive recomb inant was identified by PCR analysis, HindIII and BamHI restriction analysis and Sequence analysis. Results: A 400 bp DNA fragment was amplified from the recombinant. Sequence analysis and restriction digest demonstrated tha t the mcpr1 gene was successfully inserted into pcDNA3.1/V5-His B plasmid. Conclusion: The eukaryotic expressed vector pcDNA3.1/V5-His B/ mcpr1 has been successfully reconstructed.
