New Mode in Parasites Experimental Teaching --Application and Experience of Interactive Teaching with Digital Microscope System

In order to improve the parasites experimental teaching quality, Digital Microscope System is used to replace the ordinary optical microscope in the teaching of eggs, imagoes, and tissue slices. The new model of experimental teaching, integrating modem information technology into the parasite experimental teaching, gives full play to the students＇ learning enthusiasm, initiative and creativity and improves the quality of experimental teaching. And at the same time, it provides a basis for the microbiological and pathological experimental teaching reform.

Microscopic Inspection on Developmental Process of Myeloma Cells

The developmental process of Myeloma cells under a digital optical microscope has been inspected and monitored by using time-lapsed recording technique. Myeloma cells were cultured in medium contained 20% and 50% of Fetal Bovine Serum （FBS）, respectively. Inspection and monitoring for 6 hours showed the effect of the FBS to mobility, proliferation rate, and development of cell cycle phases of Myeloma cells. Using time-lapsed data, the speed of cells was 3.5-6.0 pm/s when using FBS 20% and increased to 5.0-8.0 p.m/s when using FBS 50%. The rate of cells decreases from 2 cells/hr when using FBS 20% to 1/6 cells/br when using FBS 50%. The cells division process is signified by the change in gray level and it took every 50-70 minutes.

3D digital image microscope system-assisted vasovasostomy and vasoepididymostomy in rats

Optimal vision and ergonomics are essential factors contributing to the achievement of good results during microsurgery.The three-dimensional(3D)digital image microscope system with a better 3D depth of field can release strain on the surgeon's neck and back,which can improve outcomes in microsurgery.We report a randomized prospective study of vasoepididymostomy and vasovasostomy using a 3D digital image microscope system(3D-DIM)in rats.A total of 16 adult male rats were randomly divided into two groups of 8 each:the standard operating microscope(SOM)group and the 3D-DIM group.The outcomes measured included the operative time,real-time postoperative mechanical patency,and anastomosis leakage.Furthermore,a user-friendly microscope score was designed to evaluate the ergonomic design and equipment characteristics of the microscope.There were no differences in operative time between the two groups.The real-time postoperative mechanical patency rates were 100.0%for both groups.The percentage of vasoepididymostomy anastomosis leakage was 16.7%in the SOM group and 25.0%in the 3D-DIM group;however,no vasovasostomy anastomosis leakage was found in either group.In terms of the ergonomic design,the 3D-DIM group obtained better scores based on the surgeon's feelings;in terms of the equipment characteristics,the 3D-DIM group had lower scores for clarity and higher scores for flexibility and adaptivity.Based on our randomized prospective study in a rat model,we believe that the 3D-DIM can improve surgeon comfort without compromising outcomes in male infertility reconstructive microsurgery,so the 3D-DIM might be widely used in the future.
