ABSTRACT
Objective The objective of this article is to attempt to propose the endovascular repair principles of distal-end tear of Stanford type B aortic dissection.Methods The vascular surgery of xinjiang uygur autonomous region people's hospital received and cured 101 patients of Stanford B aortic dissection from January 2013 to January 2015.The patients are divided into two groups according different treatment principles:(1)There are 57 cases in sequential treatment group,performing endovascular repair of aortic tears from near to far,(if the tear at visceral artery is not treated then the distal-end tear is also not treated);(2) There are 44 cases in non-sequential treatment group,not performing endovascular repair of aortic tears from near to far (the tears involving visceral artery are not treated and the remaining distal-end tears are performed endovascular repair).After operation,carry out statistical analysis between two groups on the growth rate of aortic diameter of the coeliac axis,occurrence rate of main discomfort complaint,false lumen thrombosis rates.Results After operation,between the two groups,the growth rate of aortic diameter of the coeliac axis is obvious difference(P ＜ 0.05),that the sequential group is with a low rate;there are obvious differences on the occurrence rates of main discomfort complaint and false lumen thrombosis rates (P ＜ 0.05),that the sequential group is superior to the non-sequential group.Conclusions After a preliminary clinical study,we get a conclusion that when treating distal-end tears of Stanford type B aortic dissection,sequential treatment is better than non-sequential treatment.
ABSTRACT
〔Abstract〕 Based on analyzing the background of generic drugs research and development, the paper elaborates the utilization meth-ods of drugs invalid patents, including information sources optimization and retrieval, invalid patents selection indexes and methods, in-fringement avoidance strategy.It takes the gastrointestinal stromal tumor drugs for example to find out drugs which can be imitated, pros-pects the future application of invalid patents information.
ABSTRACT
Objective To assess the treatment of splenic artery aneurysms(SAA) and curative effect evaluation.Methods Twelve SAA patients treated in our hospital from January 2012 to May 2014 were clinical analyzed.The male in Twelve patients was 4 man and others were female.The vagus splenic artery aneurysms are originated from the superior mesenteric artery,tumors are single,from 1.5cm to 2.8cm in diameter,an average of 2.1cm.Twelve cases were performed surgery,4 patients underwent elective surgery,interventional embolization of the splenic aneurysm in 3 patient,The others were performed interventional embolization + superior mesenteric artery covered stents.Results Technical success was achieved in all twelve patients,2 patients had adverse effects such as abdominal pain,fever,etc.There revealed no aneurysm recurrence was found.Twelve patients were followed for 6-24 months,the follow-up by examinations with electronic computer X-ray tomography or color Doppler ultrasonic as well as angiography every 3 months.One patient died of severe abdominal bleeding 1 year later after the operation and the other eleven patients remained in good condition with no occurrence of re-canalization of the lesions.Conclusions For the vagus splenic aneurysm with suitable for anatornic conditions,cavity therapy is safe and effective,for the vagus splenic aneurysm involving hepatic artery,need to open surgery for vascular remodeling.
ABSTRACT
Objective To analyze the overall developmental stages of traditional Chinese materia medica patent technology in China and abroad and the causes of the differences. Methods In this study, the Shanghai Intellectual Property Information Platform, Thomson Innovation, Derwent Innovations Index were utilized and graphic illustration method for patent technology life cycles was used to determine the overall developmental stages of traditional Chinese materia medica patent technology in China and abroad. Results The numbers of applications for patent traditional Chinese materia medica and their applicants were obtained. With information of the two parameters, the text made a preliminary prediction of overall trend for the number of applications. Conclusion The patent technology of traditional Chinese materia medica progressed into developing stages in China and appeared the feature of mature or recession stage abroad.
ABSTRACT
Objective This study analyzes the main technical fields and their mutual correlation concerning the international patents of acupuncture to provide decision support for the strategy of developing acupuncture related products.Methods Derwent Innovation Index was applied as the data source,Thomson Data Analyzer was adopted as the main analyzing tool,and the co-occurring clustering spectrum analysis method of international patent number (IPC) was used.Results Based on the retrieval and analyzed results,the main classification of international patent of acupuncture and the technical association diagram of Chinese medicine acupuncture patents were formed.Conclusion The main technical fields of acupuncture international patent included acupuncture needles,acupuncture instruments combined with drug and acupuncture instruments combined with modem physical methods as well as the point health care products.Among them,the methods applied in acupuncture,namely the magnetic therapy method,laser therapy,thermal therapy,roller and ball massage adopted in acupuncture point massage instruments which combine traditional herbal medicine,have already been the research hotspot of current acupuncture patent products.
ABSTRACT
Objective:to construct and apply the bilingual teaching materials.Methods:teachers in Nantong university compiled Pathology,Direction of pathological experiment and test which were written in both Chinese and English as the in-class bilingual teaching materials according to the characteristics of Chinese students,meanwhile compiled Pathological formative exercises,Pathological listening and reading,Basic problems of modern clinical pathological research for students' practice and elective course materials or reading materials after class.Results:A series of 4 bilingual teaching materials were all published by science publishing house except Pathological listening and reading was used as in class teaching materials.These teaching materials played an important role in the bilingual pathological teaching in Nantong university.Conclusion:The construction and innovation of bilingual teaching materials are basic guarantees for bilingual teaching.
