Objective To study the influence of hydrocortisone sodium succinct by intravenous infusion or continuous intravenous micro pumping on the vital signs,shock duration,blood glucose and mortality in the patients with severe sepsis secondary shock.Methods Ninety patients with septic shock treated in our hospital from June 2014 to September 2016 were selected and divided into the control group and observasion group by using the random number table method,45 cases in each group.The control group was given hydrocortisone sodium succinct 200mg/d by slow intravenous drip for 2h,while the observasion group was given hydrocortisone sodium succinct 8.33mg/h by continuous intravenous micro pumping.The two groups were treated for continuous 5 d.The blood glucose,hemodynamics and prognosis were compared between the two groups.Results In the observasion group,the blood glucose indicators such as the time window of high blood glucose,LAGE,MBG and CV levels were lower than those in the control group,the difference had statistical significance (P<0.05).The hemodynamic indicators such as HR,CVP and MAP between the two groups before treatment and at 6,24 h and 5 d after treatment had no statistical difference between the two groups (P>0.05).The shock duration,ICU stay length,total hospital stay and 28 d mortality in the observasion group were lower than those in the control group,but the difference between the two groups had no statistical significance (P>0.05).Conclusion Continuous intravenous micro pumping of hydrocortisone sodium succinct can stabilize blood glucose fluctuation range in the patients with septic shock,but the hemodynamic indexes and prognosis have no obvious improvement.

The higher medical education in China starts late and needs further exploration and improvement.While in Germany,it is elite education with a long history.Compared with China,in curriculum setting,Sociology,Medical health security,Humanities and Social Sciences and Organ system classification courses are more emphasized,and in terms of degree,it only has Doctor degree but with higher quality in Germany.Higher medical education in China will also take the path of the elite education.We can learn from the German medical education development experience and pay attention to solving the lack of the curriculum by supplementing social medicine and medical health security,increase the autonomy of the instructors in the training process,strengthen the medical students' social responsibility,and improve the quality of higher medical education in China.

Objective:To study the effects of nitrous oxide(N2 O)sedation in the management of dental fear(DF)for dental treat-ments of children.Methods:66 cases of pediatric patients(aged 6 to 14 years)were given N2 O sedation for dental treatments.The heart rate(HR)and oxygen saturation(SpO2 )were measured before and after N2 O inhalation.N2 O effective concentration was eval-uated by Ramsay sedation score and Houpt behavior score.Results:The effective concentration of N2 O sedation was 25% -70%(49.6% ±12.1%),the maximum endurance concentration 35%-70% (56.4% ±10.1%).The Ramsy scores of N2 O sedation was (2.3 ±0.6).After N2 O inhalation,all patients could receive verbal demand during the treatments.The HR decreased(P <0. 05)and the Houpt behavior score increased(P <0.01).Before and after N2 O inhalation SpO2 had no significant difference(P >0.05).Conclusion:N2 O inhalation at 25% -70% is safe and effective in the management of DF for dental treatments of children.

Objective To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) with scissors knife in difficult cases.Methods A total of 36 sessions of ESD in 34 patients were performed from May 2010 to May 2012 with application of new scissors knife.The complications and followup outcomes were recorded.Results All lesions were removed successfully with an en bloc resection rate at 91.7％.Delayed bleeding occurred in 2 patients (5.6％),and both of them were cured sucessfully with endoscopy.No perforation happened and the average hospitalization time was 5 days.Follow-up endoscopy performed 6 or 12 months after ESD in 6 patients revealed no recurrence or residual lesions.Other patients are under follow-up now.Conclusion The scissors knife is easy to manipulate,which can ensure the safety and efficiency of ESD.

Objective: To understand the relationship between chloroquine resistance and the virulence of Plasmodium berghei. Met hods: Dynamic changes of histopathologic features of livers, spleens, brains, hearts, lungs and kidneys of mice infected with the chloroquine-sensitive (N) and the chloroquine-resistant (RC) strains of P. berghei were compared. Results: In mice infected with the N strain, deposition of heavy hemoz oin in livers and spleens, congestive edema in lungs, and congestion and embolis m in the brain capillaries were observed. The histopathologic features revealed ac ute inflammatory reaction. In mice infected with the RC strain, histopathologic variations of livers and spleens were associated with changes of parasitemia. In terstitial pneumonia was displayed in lungs. There were chronic histopathologic changes of the organs in the mice infected with RC strain. Conclusion: The mice infected by the N strain with potent virulence die due to adher ence of the erythrocytes to microvascular endothelia and embolism of the microva scula, especially in their brain. Immune responses of the mice infected by the R C strain with poor virulence may be a delayed-type hypersensitive inflammation a ssociated with CD4+Th1 at an early stage of the infection, but may become anti body-dependent immune response assisted with CD4+Th2, which play a key role in elimination of the malaria parasites at later stage of the infection.
