ABSTRACT
Objective:To investigate the recent and long-term efficacy and safety of pancreaticoduodenectomy for pancreatic head carcinoma and periampullary carcinoma.Methods:82 cases of pancreatic cancer combined with periampullary carcinoma patients admit ted in our hospital from August 2009 to June 2013 were selected and randomly divided into the control group and the observation group With 41 patients in each group.The control group received palliative surgical treatment,while the observation group underwent pancreatoduodenectomy.The operation time,hospitalization time,intraoperative bleeding volume and the incidence of complications,1,2,3-year survival rate and the recurrence rate at 1 year after operation and tumor eradication rate were compared between twp groups.Results:The amount of bleeding,operation time of observation group were significantly higher than those of the control group(P＜0.01),no signif icant difference was found in the hospitalization time between the two groups(P＞0.05);the incidence of complications in the observation group (41.46％) was significantly higher than the control group (22.96％)(P=0.03);the 2-year and 3-year survival rate of observation group were significantly higher than those of the control group (P＜0.05),the recurrence rate at 1 year after operation of observation group was significantly lower than that of the control group (P=0.04),the tumor eradication rate was significantly higher in the observation group than that of the control group (P=0.04).Conclusion:Though pancreaticoduodenectomy could prolong the operation time,increase the risk of bleeding and complications for pancreatic head carcinoma and periampullary carcinoma,but it could effectively reduce the possibility of recurrence after operation,significantly improve the long-term survival rate.
ABSTRACT
As a weapon of mass destruction ,the biological weapon , composed of biological warfare agents and their re-lease devices,is characterized by strong pathogenicity , large pollution areas, various routes of infection, low cost, user-friendliness and a large number of impact factors .Although the United Nations has banned the use of biological weapons , there are still some countries and regions that continue biological weapon researches .In addition, illegal use of biological warfare agents in the field of terrorism and non-military arena poses a serious threat to public safety .Early detection of bio-logical warfare agent use and determination of its type are crucial to biological weapon defense and epidemic control .There-fore, to enhance researches on rapid detection and early warning of biological warfare agents is of great significance .This paper reviews the main technologies currently applied to the field of biological warfare agent detection and their progress .
ABSTRACT
The wireless real-time monitoring system for body temperature is based on electronic thermometry and wireless communication technology. It can measure and store the patient's body temperature during the desired time span, and can transmit the data to the computer terminal or the cell phone terminal through wireless transmission system.
ABSTRACT
Medium filtering efficiency and loading capacity have been evaluated using staphylococcus aureus aerosol,0.75?m NaCl aerosol and Ecoli.F2 phage aerosol,and the face fit factor of actual wearing has been tested under eight predefined activities.The results have shown that the filtration efficiencies of respirator for the three kinds of tested aerosol were above 99 percent,the breathing resistance was less than 250 Pa,and while the load reached 150mg,the breathing resistance of the respirator was still below standards.The fit factors of most of the objects were over the detection capacity of the international standard test set.Our mask offers the best biological protection quality of all the protection equipments in international market.The new biological protective respirator comes to the equal protection result of the half face mask.It can be stored in a flat surface construction form,while be used in the cavity construction style.It is convenient for the troops to be equipped and applied for its smaller physical volume and lighter weight.
