Pulmonary valve stenosis is a common congenital heart disease,and its early diagnosis and treatment can improve growth and prognosis in children with pulmonary valve stenosis.With the development of the diagnostics and treatment,percutaneous balloon pulmonary valvuloplasty has replaced surgery as the first choice for isolated pulmonary valve stenosis.This paper reviews the recent progress in diagnosis and treatment of pulmonary valve stenosis.

Carotid artery stenting (CAS) for treating carotid artery stenosis is a recent developed technique which is less invasive and complications. This paper reviewed the progress, procedure, and complications of carotid artery stenting.

Being the kernel of functional gene group,the field of protein group becomes the focal point of life science research in 21th century.SELDI,which is based on the combination of chip technology and mass spectrum technology,has become the main method for filtrating tumor marker in clinical research.This paper introduces the basic principle of SELDI system and summarizes the application of SELDI to tumor marker detection in galactophore cancer.

By the research of status quo of TCM human resources in the rural areas here,the essay analyses the training of TCM human resources and the aspiration of furthur education,explores the polices and measures about how to arrange TCM human resources reasonably in rural areas,promotes the development of TCM in the rural areas,and achieves the hygienic justice eventually.

OBJECTIVE: To investigate the economic effects of three chemotherapy schemes in the treatment of non-small cell lung cancer(NSCLC).METHODS:114 cases of advanced NSCLC were randomly divided into 3 groups, group MVP, group NP and group TP. The cost effectiveness of the 3 groups were compared using pharmaceutical economics. RESULTS: 3 schemes costed 1 875.2 yuan,5 565.2 yuan and 8 369.6 yuan respectively; The effective rates were 33.2%,34.1% and 40.5% respectively. On the basis of scheme MVP, scheme NP and TP increased cost of 4 100 yuan and 889.64 yuan respectively for 1% increase in effective rate. CONCLUSION: Scheme TP is the preferred choice.

Objective To observe the effects of cigarette smoke extract (CSE) on the proliferation and secretion of hydrogen peroxide (H2O2) in human lung fibroblasts (HLFs) induced by transforming growth faetor-β1(TGF-β1).Methods Cultured HLFs were divided into a normal group and a model group induced by TGF-β1 (5 ng/mL),then intervened with CSE at different concentrations (0% ,2.5% ,5%, 10%, respectively).Brdu ELISA assay was used to detect cell proliferation.H2O2release from cultured cells was assayed using a fluorimetric method.Cellular localization of H2O2 and expression of α-SMA were performed using a fluorescent-labeling strategy.Results TGF-β1 stimulated group showed positive expression of α-SMA, implying TGF-β1 had induced fibroblasts to differentiate into myofibroblasts.In TGF-β1 stimulated group,2.5% and 5% CSE promoted cell proliferation (P < 0.01 or 0.05), while 10% CSE inhibited cell proliferation (P < 0.01).In the normal group, both low and high concentration of CSE inhibited cell proliferation (P < 0.01 or P < 0.05), and the inhibition effect was dose-dependent.HLF induced by TGF-β1 generated low constitutive levels of extracellular H2O2 that was markedly enhanced by CSE treatment (P < 0.01).Pretreatment with DPI, an inhibitor of NADPH oxidase, abolished secretion of H2O2.Cellular localization of H2O2 by a fluorescent-labeling strategy demonstrated that extracellular secretion of H2O2 is specific to the myofibroblast.Conclusions Low concentration of CSE can promote myofibroblast proliferation, and markedly increase extracellular secretion of H2O2.CSE possibly take part in the development and progress of idiopathic pulmonary fibrosis by increasing oxidative stress.
