Research and application discussion of cranial bone model preparation method based on three-dimensional reconstruction and 3D printing technology.

Purpose: The aim of this study was to find an alternative method to meet traditional human anatomy teaching and clinical needs in order to solve the problem of cranial specimen attrition and specimen resource shortage due to long-term use.

Methods: We performed a computed tomography (CT) scan of a well-preserved male cranial specimen and used Mimics 19.0 software for 3D reconstruction and cranial block separation.

[Combining high-risk human papillomavirus DNA test and cytological test to detect early cervical dysplasia].

Objective: To assess the value of combining high-risk human papillomavirus (HPV) DNA test and cytological test in detection of early cervical dysplasia.

Methods: During January 2003 to June 2004, a total of 5210 women were screened by combining high-risk HPV DNA test (hybrid capture II, HC-II) and cytological test (liquid-based ThinPrep cytology test), and the abnormal cytological or HPV DNA findings were further biopsied under the colposcope.

Results: The age of the patients was between 17 to 80, the average was 34 +/- 9.
