Reflections on improving the teaching quality of basic surgery / 中华医学教育探索杂志

The Surgery foundation is a course that emphasizes both theory and practice. It is an important part of surgical study and a compulsory basic course for medical students. The teaching quality of this course is directly related to the future level of clinical operation of medical students, and the good teaching methods and means are one of the key factors to determine the quality of the course. In this paper, the reform of teaching means and methods of this course are discussed, so as to further improve the teaching quality and summarize the experience and advice.

Horseshoe kidney with retrocaval ureter: one case report / 中华医学杂志(英文版)

Horseshoe kidney and retrocaval ureter are uncommon congenital anomalies of the genitourinary system that are easily diagnosed by typical imaging features. Both anomalies presenting in one patient is a rare disease characterized by isthmus of horseshoe kidney between the abdominal aorta and inferior vena cava. The clinical diagnosis and treatment of horseshoe kidney with retrocaval ureter remain a challenge. Here, we reported a case of a 44-year-old man with the two anomalies who was preoperatively diagnosed by unenhanced computed tomography scanning immediately after retrograde pyelography. The literatures on such combined anomalies are reviewed and the diagnostic evaluation and surgical management of this rare entity are discussed.

Expression of cellular FLICE-like inhibitory protein long form mRNA in colon cancer and its clinical significance / 第二军医大学学报

Objective: To observe the expression of cellular FLICE-like inhibitory protein long form (cFLIPL) mRNA in colon cancer and to assess its relationship with the biological behavior and prognosis of colon cancer. Methods: Expression of cFLIPL mRNA was examined in 86 colon cancer samples and their corresponding normal tissues by semi-quantitative RT-PCR technique. Expression of CEA and P53 in the colon cancer samples was assayed by SABC immunohistochemistry staining. The plasma levels of CEA and CA19-9 were determined by microparticle enzyme-linked immunoassay (MEIA) before operation. Colon cancer tissues were divided into cFLIPL mRNA high expression group and low expression group based on the average value of all the 86 patients. The relationship between the high expression of cFLIPL mRNA and the different clinical features and pathological characters was determined. We also compared the 5-year accumulative survival rates of the 2 groups. Results: The expression of cFLIPL mRNA in the colon cancer tissues was significantly higher than that in the matched normal tissues (0.59±0.10 vs 0.36±0.10, P
