Objective To explore the association between epicardial adipose tissue (EAT) thickness and left ventricular remodeling,left ventricular dysfunction in dilated cardiomyopathy (DCM).Methods One hundred and sixteen patients with DCM (DCM group) and 76 healthy subjects (control group) were examined by ultrasoundcardiogram.Left ventricular end-systolic diameter (LVESD),left ventricular end-diastolic diameter (LVEDD),left ventricular end-systolic volume (LVESV),left ventricular end-diastolic volume (LVEDV),left ventricular end-systolic volume index (LVESVI),left ventficular end-diastolic volume index (LVEDVI),left ventricular ejection fraction (LVEF) and EAT thickness were measured or calculated,and the relationship was evaluated.Results EAT thickness in DCM group was significantly lower than that in control group [(4.7 ± 1.2) mm vs.(7.6 ± 2.1) mm],and there was statistical difference (P ＜ 0.05).The linear correlation analysis results showed there was positive correlation between EAT thickness and LVESD,LVEDD,LVESV,LVEDV,LVEDVI,LVESVI (r =0.236,0.220,0.245,0.256,0.282,0.279,P ＜ 0.05),and there was no relationship between EAT thickness and LVEF (r =0.134,P ＞0.05).Conclusions In patients with DCM,there is a correlation between EAT thickness and ventricular remodeling.There is no correlation between EAT thickness and left ventricular dysfunction.

Objective To study the expansion and purification of human retinal progenitors cultured in vitro.(Methods Human) embryonic retinal progenitor cells(RPCs) were cultured.The characteristics of neural stem cell were observed.The expression of Nestin was examined flow cytometry(FCM) for the comparsion between the primary and secondary passages.The differentiation of RPCs had been observed after that they had been cultured in different conditions.Results Human RPCs had proliferated and formed cell clusters with a shape of neurosphere.After digestion,the scattered progenitors formed secondary neurosphere-like cell clusters.The cells in those clusters expressed Nestin and were negative for the mature retinal cell proteins.After spontaneous differentiation,the retinal progenitors expressed special proteins of mature retinal cells,including neuron specific enolase(NSE),glial fibrillary acidic protein(GFAP),protein kinase C(PKC) and Syntaxin-1.The expression of Nestin in the secondary culture passage was(39.3?18.9)%,which was significantly higher than that of the primary passage [(28.7?17.7)%](P

The paper discusses the importance of bioethics,which is a love of life.Bioethics is the ethics of love.Three parts are included in the paper: love is foundation of bioethics;love is core of existence of bioethics;love impels bioethics to further develop.Love instructs the choice of objective bioethics in the toleration circumstance.Furthermore,love can impel the construction of bioethics in the progress of medical beneficence development.

Objective To study the protective effect of Qidan Tongmai Tablet (QDTMT) on the (injury) induced by acute myocardial ischemia. Methods Acute myocardial ischemia was induced by sc isoproterenol (Iso, 5 mg/kg) into SD rats pretreated with ig QDTMT (2 g/kg) for two weeks. Activities of Ca~(2+)-(ATPase) in myocardial mitochondria and content of Ca~(2+) in myocardium and myocardial mitochondria were determined by colorimetric method. The changes of myocardial ultrastructure were investigated by means of transmission electron microscope. Results Compared with the controls, activities of Ca~(2+)-(ATPase) in mitochondrion were strengthened in QDTMT group and the content of Ca~(2+) was decreased ((P

Radiotherapy is an important treatment for malignant tumors, but it will have a negative impact on the reproductive function of young female patients.In recent years, the measures to protect female fertility are increasing, including clinical mature technologies such as embryo cryopreservation and mature oocyte cryopreservation; highly experimental technologies such as immature oocyte in vitro fertilization and ovarian tissue cryopreservation and transplantation.In addition, the application of stem cells and the proposal of artificial ovary also show great prospects in the protection of female fertility.This paper reviews the research progress of female fertility protection strategies in radiotherapy.

Objective To identify Mallotus panicutus (lam) Muell.Arg and explore the acute toxicity.Methods Pharmacognostic identification and chemical reaction methods were adopted to the identification.The maximum concentration and maximum volume of ethanol extracts of M.panicutus (lam) Muell.Arg were given via intragastric administration in mice to observe the toxic and side effects after 14 days.Results The chemical reaction showed M.panicutus(lam) Muell.Arg concluded the constituents such as flavone and saponin and there was no acute toxicity in mice.After 14 days,the growth rate of mice weight of blank group and drug group were 73.5% and 62.9% (P ＞ 0.05).Conclusion The results could be taken as the reference for analyzing the quality of this drug and guiding the clinical medication.

IgG4 related disease (IgG4-RD) is a systemic disease which was named and accepted in recent years.IgG4-RD is a multiorgan-involved disease, mainly including pancrease, parotid gland, bile duct, liver, etc.The study on the relationship between IgG4 and orbital disease is relatively few.In recent years, our study group aimed directly to the relationship between IgG4 and common orbital disease, including benign lymphoepithelial lesion of lacrimal gland,idiopathic orbital inflammatory pseudotumor, orbital lymphoma, etc.We found that IgG4 was associated with the pathogenesis and progression of these diseases.This article addressed systematically the pathogenesis of IgG4 related orbital disease and evaluated the values of IgG4 in diagnosis,differential diagnosis,treatment and montoring of these orbital diseases based on related literature and reseaching results from our study group,in order to deepen the recognition of IgG4 related orbital diseases in ophthalmologists.

Apoptosis is a cell suicide process with a major role in development and homeostasis in bodies. Dysregulation of apoptosis, involved with inhibitors of apoptosis (IAPs), contributes a variety of disease states including cancer. The recent progress of members of IAPs family and the anticancer strategy against IAPs is reviewed in this paper.

RNA interference which focuses on siRNA becomes a studying focus in malignant tumor of gene therapy due to its high efficiency and effect, the sequence of specific characteristics and action fast. In recent years many research shows that constructing and transfecting malignancy related gene targeting specific siRNA, can effectively suppress tumor growth and invasion. Combination with other conventional treatments can improve the curative effect. It's a promising new method of gene therapy in head and neck neoplasms.

Objective To explore the effects of cannabinoid receptor agonist WIN55,212-2 preconditioning on spinal cord ischemia reperfusion injury in rats.Methods A total of 32 male Sprague-Dawley rats was randomly divided into four groups (n =8):sham group,control group,dimethyl sulfoxide(DMSO) group which was given intraperitoneally DMSO 0.3 ml 30 min before ischemia reperfusion,and WIN group which was given intraperitoneally WIN55,212-2 1 mg/kg 30 min before ischemia reperfusion.Each rat was neurologically assessed at 24 h and 48 h after reperfusion by Tarlov scale,and the number of normal motor neurons at anterior horn of the spinal cord was recorded.Res uits The Tarlov scale of WIN group was significantly higher than that control and DMSO groups (P ＜ 0.05).There were more normal motor neurons at anterior horn of the spinal cord in WIN group than those in control and DMSO groups (P ＜ 0.05).Conclusions Cannabinoid receptor agonist WIN55,212-2 preconditioning might attenuate spinal cord ischemia reperfusion injury.
