The aim of the eight year medical education program is to cultivate high-leveled and high qualified clinical and research personnel.Constructing forensic interest group for medical students of eight year program can not only cultivate the students' English learning,innovative thinking and practice ability,which is their Achilles heel but also combine eight year medical education with forensic science teaching reform.

Objective To investigate the clinical characteristics,surgical treatment and outcome for patients with duodenal stromal tumor.Methods Data of 40 patients with stromal tumor of duodenum were reviewed retrospectively.Results All patients received resection including local resection in 14 cases,segmental resection of the duodenum in 17 cases,and pancreaticoduodenectomy in 9 cases.38 cases were followed-up,and two were lost.The median follow-up was 59 months (range 3-240 mos).The 1,3,and 5-year overall survival rates were 92％,76％ and 68％,respectively.No recurrence was found in very-low-risk tumor (n =1) and low-risk turmors (n =4).The 1,3,and 5-year overall survival rates for intermediate-risk tumors were 95％,80％ and 70％,respectively;and those were 69 ％,31％,and 0 for high-risk tumors,respectively.14 of 33 cases (42％) suffered from recurrence after radical resection for intermediate or high-risk tumors.33 postoperative cases received treatment with Imatinib (Glivec) for more than one year,and one case developed recurrence at 2.5 years after operation.4 patients with synchronous liver metastasis received palliative resection and Imatinib,and two survived more than 1 year.Conclusion Surgery is the first choice for duodenal stromal tumor,and Imatinib should be administered for high-risk disease after surgery.

Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.
