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.

Objective To study the influence of pre-hospital emergency professional technology for nerve function,disability rate and mortality in the critically injured patients.Methods One hundred critically injured patients were selected as pre-hospital group,100 critically injured patients who immediately went to hospital emergency department were selected as hospital group.The Glasgow coma score,shock index,trauma index,mortality were compared between the 2 groups.Resuts There was no statistical difference in Glasgow coma score at 12 h after treatment between the 2 groups (P ＞ 0.05),Glasgow coma score at 24 h after treatment in pre-hospital group was significantly higher than that in hospital group [(13.9 ± 3.6) scores vs.(11.9 ± 4.8) scores],there was statistical difference (P ＜ 0.05).The trauma index at 12,24 h after treatment in pre-hospital group were significantly lower than those in hospital group (12.1 ± 5.1 vs.14.6 ± 4.8,11.9 ± 4.6 vs.14.3 ± 3.8),there were statistical differences (P ＜ 0.05).There were no statistical differences in shock index at 12 and 24 h after treatment and mortality (P ＞0.05).Conclusion Pre-hospital emergency professional technology has important the role for the treatment of critically injured patients.

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.

The application of standardized patien(tSP)has not been widely used in China. This article summarized some experiences of using SP in pediatric clinical teaching such as choice and training SP,the writing of scenario,and the score criterion in OSCE. We concluded that the use of SP had irreplaceable advantages.

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.

With the 2015 deadline for fast approaching the millennium development goals ( MDGs) , attention has turned to what should follow.The post-2015 development agenda is due to be adopted by the world leaders in a high-level summit which was held in New York in September 2015 .This paper summarizes the health-related MDGs progress and suggestions, describes the negotiations process on the health-related post-2015 development agenda, dis-cusses the proposed framework of the sustainable development goals and its indicators, and then provides some sug-gestions on the Chinese participation in the post-2015 development agenda as well as in the upcoming high-level sum-mit.

ObjectiveTo explore the clinical effect of the different surgical treatment for patients with inguinal hernia.Methods98 patients with inguinal hernia were randomly divided into two groups and 49 cases in each group.The observation group was given filling tension-free hernia repair,the control group using traditional hernia repair.The postoperative follow-up were compared in clinical efficacy and recurrence.ResultsIn the observation group and control group,the duration of postoperative pain,surgical time and patient recovery time was 93.9％ (46/49) vs 81.6％ (40/49) (x2 =2.645,P＜0.01),(45.2 ±7.2)min vs (51.4 ±6.4)min(P ＜0.05),(60.8±5.4) min vs (71.4 ± 6.7) min ( P ＜ 0.05 ),( 2.0 ± 2.1 ) d vs (4.9 ± 1.8) d ( P ＜ 0.05 ).Postoperative follow-up found that both groups of patients relapse rate was statistically significant( x2 =3.279,P ＜0.01 ).ConclusionTwo different surgical treatment of inguinal hernia,the tension-free hernia repair compared with the traditional hernia repair was more suitable for the body,surgery time and recovery time was short,reducing the relapse rate in patients with inguinal hernia,was an effective means of treatment.

Mechanical stapling devices have been widely applied in the gastrointestinal surgery since the 1950s because of its advantages of easy manipulation,less time consumption and low incidence of postoperative complications.With modification of these devices and technical proficiency,mechanical staplers have been introduced into several surgical procedures in hepatopancreatobiliary surgery including pancreatoduodenectomy,hepatectomy,cholecystojejunostomy,gastroenterostomy,cystogastrostomy and enteroenterostomy.Currently,there are no guidelines or consensus in China concerning the use of mechanical stapling devices. Current advances in mechanical stapling devices and complications in the clinical practice are discussed in this article.
