Objective: To research the application of dynamic-network probation in combination with traditional clinic probation in surgical practice teaching. Methods:Sixty four people in the undergraduate 2012(1, 2 session) set as the experimental group. 40 people in the undergraduate 2012(biochemical class) set as the control group. The traditional clinic probation was applied to the control group. The traditional clinic probation was applied to the control group. The dynamic-network probation in combination with traditional clinic probation was applied to experimental group. The teaching effects were evaluated and compared roundly. Results:The teaching effects of experimental group was significantly better than control group in all respects (x2=7.512, x2=6.797, x2=7.778, x2=4.768, x2=8.541;P<0.05). Satisfaction ratio of experimental group was significantly higher than that of control group in all respects of surgery teaching (x2=4.475, x2=5.900, x2=5.005, x2=5.904, x2=4.502; P<0.05). The examination performance of experimental group was significantly better than control group in theoretical knowledge and clinical skills testing (t=25.840, t=19.319;P<0.05). Conclusion:Dynamic-network probation in combination with traditional clinical probation has a great effect on surgical practice teaching and worth to be applied.

Objective To explore the applicated value of Doppler ultrasound,X-ray mammography and MRI in early diagnosis and differential for breast cancer.Methods 182 cases examine femaled patients,which were hospitalized to breast lumps as the object of study,they were confirmed by Doppler ultrasound,X-ray mammography and MRI three checks.Caccording to the patient after surgery,the pathology results were used to diagonosed the value of the three detection methods.Results 182 patients with breast cancer and 143 cases(78.7％),benign tumors and 39cases(21.3％),the sensitivity of MRI was significantly higher than the other two,three associated with the accuracy of the examination results was significantly higher than that of each individual(P ＜0.05),the difference was statistically significant.Conclusion Doppler ultrasound,X-ray mammography and MRI are used in breast cancer in the early diagnosis,which have their own advantages,the combination can increase the accuracy to a certain extent.

Transjugular intrahepatic portosystemic stent shunt(TIPSS)was per- formed in 30 cases of liver cirrhosis with portal hypertention.Operations were susceeded in 29 cases with only one failure.Complications happened in 7 cases,In 29 patients the average blood bilirubin was 25.12?9.80 mmol/l before TIPSS turning to 50.46?34.50 mmol/l after TIPSS;The average blood amonia was 152.33?65.30 ?g/dl before TIPSS changing to 233.33?599.96 ?g/dl after TIPSS.The contributing factors were due to liver function state and shunting channel diameter for causing hepatic encephalopathy and jaundice.Other complications such as multipule liver abscesses,pneumonia,bacteriemia were related to the accompanied diseases and operative technique.The authors introduced the principles of pre- vention and treatment of complications,together with the indications and contraindications of TIPSS.

Objective To study the natural history of HIV infection among paid blood donors(PBD).Methods Two thousand three hundred and sixty four individuals infected with HIV/AIDS via blood donation in twelve villages of Henan province were included in this study,Retrospective data were analyzed in combination with a cross-sectional survey.Results The number of deaths were 709 among these 2 364 subjects under study by the end of 2004,with a mortality rate of 30.1%.Among 712 deaths,32.8% were companied with serious lung infections,18.1% were complicated with serious diarrhea,8.2%-with central nervous infections,8.2%-with cirrhosis,6.6%-with various types of cancers,3% died of suicide and 23% died with unclear cause.Of them 544 AIDS patients died before the ARV treatment was available in rural areas of Henan at the end of 2002,with a mortality rate of 23.0%.The median survival period for individuals with HIV infection was 9.5 years,and the median incubation period was about 8.5 years.Conclusion The median aurvival period for individuals with HIV infection via blood donation in rural areas of Henan was 9.5 years and the median incubation period was about 8.5 years among them.

Congenital cataracts is the leading cause of visual disability in children worldwide.With the evolution of molecular biological technique,the researches of inherited congenital cataract mainly focus on localization and fuction characterization of the disease-associated gene,including crystallin,connexin,major intrinsic protein gene,etc.And great progress has been made for such genes in eye development,age-related cataract,epigenetics study.Thus,great attention must be paid to the functional research about congenital cataract candidate gene.

Refractory glaucoma is one of the main blinding diseases in ophthalmology.Glaucoma drainage device implantation has become one of the main methods of refractory glaucoma.It has been widely used in clinic because of its advantages of safety,effectiveness and less complications.After a large number of clinical applications and innovative development of minimally invasive glaucoma surgery,glaucoma drainage device implantation shows its good treatment prospects.In this paper,the structural features of glaucoma external drainage device (Molteno,Schocket,Baerveldt,Human aqueous drainage,Krupin,Ahmed,Joseph,Whites,Optimed drainage device) and microin vasive glaucoma surgery (MIGS) (Ex-PRESS drainage device,Xen Gel Stent,CyPass Micro-Stent,Ab interno trabeculectomy trabectome,Hydrus Schlemm canal scaffold,iStent trabecular micro-bypass stent,SOLX Gold Shunt) were summarized.The drainage device implantations for glaucoma in the role of the refractory glaucoma were reviewed.

Aiming at the difficult employment situation of marketing students of higher vocational medicine,we has made an objective analysis of the strengths and weaknesses as well as opportunities and threats based on the trend analysis tools and weigh the advantages and disadvantages to help graduates overcome the deficiencies of individual employment process and find out the existing disadvantages of school,which can provide reference for improving the employment situation of higher vocational medicine marketing.

ObjectiveTo investigate the effect of subtotal gastrectomy on glucose metabolism in patients with gastric disease combined with diabetes mellitus.MethodsThe clinical data of 126 cases with gastric disease combined with diabetes mellitus receiving subtotal gastrectomy were analyzed retrospectively,including subtotal gastrectomy Billroth Ⅱ type 69 patients (Billroth Ⅱ type group),subtotal gastrectomy Billroth Ⅰ type 57 patients(Billroth Ⅰ type group).The fasting blood glucose,postprandial blood glucose before surgery and 1,3,6 months after surgery and the improvement of glucose metabolism were compared.ResultsThere was no significant difference in the fasting blood glucose,postprandial blood glucose before surgery and 1,3,6 months after surgery in Billroth Ⅰ type group (P ＞0.05).The fasting blood glucose,postprandial blood glucose 3,6 months after surgery [ (10.7 ±2.9 ),(10.4 ± 2.3 ) mmol/L and (12.4 ± 2.6),(12.0 ±3.2) mmol/L] were higher than those before surgery and 1 month after surgery [(14.1 ±3.2),(13.4 ±3.8) mmol/L and(19.0 ±3.9),(18.1 ±4.3) mmol/L] in Billroth Ⅱ type group with significant differences (P ＜ 0.05 or ＜ 0.01 ).The improving rate of glucose metabolism in Billroth Ⅰ type group [ 7.02％(4/57) ] was lower than that in Billroth Ⅱ type group [ 92.75％(64/69)] with significant difference(P ＜ 0.01 ).ConclusionsSubtotal gastrectomy has obvious effect on improving glucose metabolism in patients with gastric disease combined with diabetes mellitus.The use of subtotal gastrectomy Billroth Ⅱ type is prior to subtotal gastrectomy Billroth Ⅰ type.
