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.

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.

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.

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.

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.

Although choledochoscope has been described as an ideal approach for cholelithiasis, larger,impacted or residual biliary duct stones could hardly be taken out. Choledochoscopic laser lithotripsy was used in 1978. At present, however, it has not wildly been applied in the biliary surgery. In this article, we reviewed the domestic and foreign literatures to state the application and prospect of choledochoscope combined with laser lithotripsy in cholelithiasis.

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 investigate the current status of cognitive level of patient safety culture in intensive care unit (ICU) nurses and analyze the influencing factors.Methods Totally 373 ICU nurses were investigated with the general information questionnaire,the Hospital Survey on Patient Safety Culture instrument (HSOPSC),the Report Barriers Questionnaire and the Condition of Work Effectiveness Questionnaire (CWEQ-Ⅱ).Results The mean rate of positive response on safety culture dimensions was 68.08％ in ICU nurses,Organizational learning-continuous improvement was the safety culture dimension with the highest positive response(89.95％),the lowest positive response was staffing(35.53％).Multiple regression analysis showed that the meaning of report,punitive culture,resources,opportunity,formal empowerment and ICU department were influencing factors of patient safety culture (P ＜ 0.05).Conclusions The level of patient safety culture in ICU nurses was medium,it remains a further improvement.Nursing managers should take targeted measures according to the influencing factors to enhance the cognitive level of patient safety culture in ICU nurses,strengthen the consciousness of safety culture,and improve the quality of intensive care.
