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.

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.

To improve standardization and consensus regarding interpreting,and reporting CT and MRI scans of the liver in patients with high-risk HCC,Liver Imaging Reporting and Data System (LI-RADS) was launched in 2011 and subsequently modified in 2013 and 2014,respectively.Major diagnostic imaging features for HCC are hyper-enhancement in the arterial phase,rapid dissection in the portal vein phase and balance phase,capsule presence and appearance,interval threshold tumor growth and tumor diameter.LI-RADS categorizes nodules recognized at CT or MRI as LR-1 (definitively benign),LI-RADS is a system of standardized criteria for interpreting liver CT and MR images of patients at risk of hepatocellular carcinoma in higher interobserver reliability and faster categorization while maintaining diagnostic accuracy.LR-2 (probably benign),LR-3 (intermediate probability of being HCC),LR-4 (probably HCC) and LR-5 (definitively HCC).According to diagnostic classification,different options for treatment recommendations are adopted by surgeons including continue standard surveillance,regular follow-up,alternative imaging method,multidisciplinary discussion,liver resection or transplantation.LI-RADS is a system of standardized criteria for interpreting liver CT and MR images of patients at risk of hepatocellular carcinoma in higher interobserver reliability and faster categorization while maintaining diagnostic accuracy.

OBJECTIVE: To compare the clinical and economical effects of foscarnet and a - interferon in treating chronic hepatitis B.METHODS:90 cases were randomly divided into two groups.Group A,foscarnet in a dose of 2.4g,i. v. ,b.i .d . for 1 month . Group B, a - interferon in a dose of 3 million units, im, q . d . for 3 months . The clinical effects were observed and evaluated with pharmacoeconomic cost - effectiveness analysis .RESL LTS In improving symptoms and liver function, two therapeutic regimes presented similar effect.But lower expenses were costed in unit effect of decreasing ALT in group B.In clearance of virus index, group A showed better effects and costed lower expenses in unit effect of HBeAg negative conversion. CONCLUSION: Both foscarnet and a-interferon presented fairly good therapeutic effect for chronic hepatitis B.In improving liver functions, two preparations showed similar clinical effect but a - interferon presented better economical effect. In antiviral efficacy,foscarnet showed better clinical and economical effects.

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.

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 observe the distribution and concentration of ~(125)I-nerve growth factor (NG-F) in rabbits' eyes after intravitreal injection and posterior juxtascleral injection.Methods Intravitreal injection(group A) and posterior juxtascleral injection (group B) were performed with the dosage of 30μg/100μl ~(125)I-NGF on left and right eyes in 45 white rabbits respectively.The γ-counts and the concentration of ~(125)I-NGF (%ID/g) of each ocular tissue was determined 15 and 30 minutes,and 1,3,6,12,24,and 48hours after injection.Results The ~(125)I-NGF diffusion in group A was faster in ocular content and ocular inner wall.The vitreous content of ~(125)I-NGF decreased gradually in group A,the curve changes in other eye tissues were normal.The concentration of ~(125)I-NGF reached the peak 3 hours after injection in aqueous humor,iris and ciliary body,retina,and choroids,but 6 hours after injection in sclera and 8 hours in cornea.The changes of concentration of ~(125)I-NGF in group B showed normal curve change.The peak time in group B were all 6 hours,in all the tissues except aqueous humor (3 hours).Except the high concentration in vitreous body caused by intravitreal injection,the concentration of ~(125)I-NGF in retina was the highest in group A.Conclusion Intravitreal injection of ~(125)I-NGF can gain higher concentration in each ocular tissue than posterior juxtaseleral injection,especially in retina.So intravitreal injection of NGF is a better ocular delivery method to treat the ocular fundus diseases.
