ABSTRACT
Objective To evaluate the clinical efficacy and adverse reactions of S-1 chemotherapy plus high-low oxygen radiotherapy synchronously in treatment of patients with locally advanced pancreatic cancer. Methods Sixty-four patients with locally advanced pancreatic cancer in Rizhao People's Hospital and the Affiliated Hospital of Qingdao University from January 2013 to October 2015 were randomly divided into study group and control group by using envelope method, in which the study group was treated with oral administration of S-1 plus high-low oxygen radiation synchronously and the control group with intravenous gemcitabine chemotherapy. The efficiency, disease control rate, clinical benefit rate, distant metastasis rate, survival rate and adverse reactions of the two groups were compared. Results The effective rates of the study group and the control group were 70.4 %(19/27)and 32.1 %(9/28),the difference was statistically significant (χ2=8.04,P<0.01), and the disease control rates were 88.9 % (24/27) and 67.9 % (19/28) (χ2= 3.56, P >0.05). The clinical benefit rates of the study group and the control group were 77.8 % (21/27) and 57.1 % (16/28) (χ2=2.66,P >0.05), and the distant metastasis rates were 63.0 %(17/27) and 71.4 %(20/28) (χ2=0.45, P > 0.05). The 1-year survival rates of the study group and the control group were 63.0 % (17/27) and 32.1 % (9/28), and the 2-year survival rates were 37.0 % (10/27) and 10.7 % (3/28), the differences were statistically significant (χ2= 5.24, P < 0.05; χ2= 5.28, P< 0.05). While there were no significant difference in the incidence of serious adverse reactions between the two groups (P> 0.05). Conclusion The treatment of locally advanced pancreatic cancer with S-1 plus high-low oxygen radiotherapy synchronously is better than that with intravenous gemcitabine chemotherapy in terms of effective rate, 1-year survival rate and 2-year survival rate,with no increase of adverse reactions.
ABSTRACT
Objective To compare and observe the effect of GASMAN software computer aided and traditional teaching method in the teaching of inhalation anesthesia. Methods 48 members of interns who need to enter the inhalation anesthesia department to study the theory of inhalation anesthesia were ran-domly divided into either GASMAN software group or traditional group with 24 people in each group, using the above two methods to carry on the study of inhalation anesthesia. After the end of the teaching course, the study effect and the satisfaction degree of the two groups of students were investigated by the written exam and questionnaire. SPSS 11.5 was used for statistical analysis, using±s to express measurement data. The results of the examination were compared with the independent sample t test, and the satisfaction survey feedback was compared with chi square test, The difference was statistically significant (P<0.05 ). Result The mean score of GASMAN software group (95.4 ±2.7) was significantly higher than that of tra-ditional group (85.0 ±3.5) (t=11.5,P=0.000). Satisfaction survey results showed that GASMAN computer assisted instruction software learning was easier for students to accept, and there were significant difference between two groups (P=0.001). Conclusion Teaching mode of GASMAN software is a good learning technique of inhalation anesthesia, which is worthy of promotion.
ABSTRACT
Objective To evaluate the ability to show anatomical structures of the normal middle ears with helical CT virtual endoscopy(CTVE).Methods CTVE were performed to observe anatomical structures of bilateral middle ears in 100 healthy volunteers.Results Anatomical structures of middle ears were displayed stereoscopically by CTVE from multiple views.But superficial and ting structures were showed pooly.Conclusion CTVE is a new noninvasive imaging tool for observe stereoscopically auditory ossicudar chains.
