Enhanced CT and CT virtual endoscopy in diagnosis of heterotopic pancreas

AIM:To improve the diagnosis of heterotopic pancreas by the use of contrastenhanced computed tomography(CT)imaging and CT virtual endoscopy(CTVE).METHODS:A total of six patients with heterotopic pancreas,as confirmed by clinical pathology and immunohistochemistry in the Sixth Affiliated People's Hospital of Shanghai Jiao Tong University,Shanghai,China,were included.Nonenhanced CT and enhanced CT scanning were performed,and the resulting images were reviewed and analyzed using threedimensional postprocessing software,including CTVE.RESULTS:Four males and two females were enrolled.Several heterotopic pancreas sites were involved;three occurred in the stomach,including the gastric antrum(n =2)and lesser curvature(n=1),and two were in the duodenal bulb.Only one case of heterotopic pancreas lesion occurred in the mesentery.Four cases had a solid yet soft tissue density that had a homogeneous pattern when viewed by enhanced CT.Additionally,their CT values were similar to that of the pancreas.The ducts of the heterotopic pancreas tissue,one of the characteristic CT features of heterotopic pancreas tissue,were detected in the CT images of two patients.CTVE images showed normal mucosa around the tissue,which is also an important indicator of a heterotopic pancreas.However,none of the CTVE images showed the typical signs of central dimpling or umbilication.CONCLUSION:CT,enhanced CT and CTVE techniques provide useful information about the location,growth pattern,vascularity,and condition of the gastrointestinal wall around heterotopic pancreatic tissue.

Investigation of ＂Four-Two-Three＂ System of Individualization Fostering Model -Taking College of Economics and Management of Hebei University of Science and Technology as an Example

＂Four-Two-Three＂ training mode system, based on the social development needs of talent personalized, divides the training process of eight semesters in four years into ＂category training＂, ＂professional training＂ and ＂personalized training＂ and phased build talent training mode of ＂four disciplines platform ＋ two capability group lessons ＋ three development path＂. In this paper, we take College of Economics and Management, Hebei University of Science and Technology as an example, explained principles, fi＇amework and content, and measures of personnel training mode and other issues in details and made a smooth implementation of security mechanism in training mode.

Research on Project-Driven Alliance between Colleges and Enterprise Teaching Mode and the Applications on Contemporary Vocational Education

In this paper, we conduct research on the project-driven alliance between the college and enterprise teaching mode and the applications on the contemporary vocational education. To achieve the aim of higher education popularization in our country, to vigorously develop vocational education is the important way. Higher vocational education for national and local economic development is the purpose of training the production, construction, management and service first line need to cultivate high quality personnel. Higher vocational education is the social demand as the primary guidance of employment education, cultivate the students should be a technology applied talents with skills. Our research proposes the novel guideline to deal with the mentioned issues which is applicable.

Traffic Patterns in the Silk Road Economic Belt and Construction Modes for a Traffic Economic Belt across Continental Plates

Plans for the Silk Road Economic Belt （SREB） include construction of two axes, two belts and two radiated areas. As a significant national strategy for China, the emphasis is on the construction of roads and achieving economic agglomeration and radiation through the construction of traffic axes. Using published literature and data analyses, this paper studied current traffic patterns between China and other regions within the SREB from the perspective of rail, ocean and air transportation. With regard to existing problems and development prospects of these three types of transportation, we propose construction modes for the traffic economic belt across continental plates and that future construction within the SREB should consider key cities as joints and arterial traffic lines as development axes, promote connecting of joints by lines, advance deep construction through joints and axes, connect lines into net, and develop informationalized traffic economic belt on the basis of trans-regional cooperation.
