Abstract The biotechnological products in the twenty-first century will be widely applied in medicine and drug, and daily intake of food. As the result of the progress of technology, people are worried about the safety of re-creating gene food and the responsibility for the clone¡¦s legal morality. Based on the questionnaire ¡§Evaluating Teacher College Students¡¦ Response to the Recognition of Contemporary Biotechnology and Their Attitude in Learning¡¨, I found that the students¡¦ response to the recognition of biotechnology is somewhat insufficient. Perhaps it will trigger the reducing teaching effect in the elementary school biotechnology course. Meanwhile, contrasted to those who are more interested in experimental choices, I designed two experimental modules in relation to the conception of biotechnology: PCR and the culture of tobacco leaves. It is hoped that in the process of carrying out experiments, students can integrate with the related conception of biotechnology according to the result of experimental modules. If we build up our biotechnological teaching at early stage, we can make students produce the more correct recognition about it. We can encourage those who are interested in it to dedicate themselfes to the biotechnological industry as soon as possible. Simultaneously, we can elevate our competition in the world. Even though the common people who are not proficient in the related field also have the ability to take part in the relevant biotechnological issues actively

The pathogenicity of irritable bowel disease (IBD) is attributed to chronic gastrointestinal inflammation with acute flare-ups. While the regulation of pathogenic inflammation is debated, evidence suggests key contributions from Type-1 and Type-17 helper T-cells and their innate counterparts, class 1 and 3 innate lymphoid cells. The differentiation of these adaptive and innate effector cells is primarily directed by so-called 'master regulator' transcription factors: T-box Expressed in T-cells (T-bet) drives development of Type-1 helper T cells and class I innate lymphoid cells, while Retinoic acid-related Orphan Receptor γ-t (RORγt) promotes development of Type-17 helper T cells and class 3 innate lymphoid cells. The relationship between these transcription factors is largely antagonistic, leading to either prominent Type-1 or Type-17 inflammation, but maladaptive plasticity and concurrent responses have been reported in IBD patients. Deciphering roles for T-bet and ROR?t in experimental settings is difficult as the absence of one often leads to the overexpression of the other. We thus created mice deficient for both T-bet and RORγt to study acute colitis in the absence of major drivers of both Type-1 and Type-17 inflammation. A widely used inducer of experimental colitis, dextran sodium sulfate, was given to mice in their drinking water to determine acute disease progression during a 7-day period using traditional metrics and kinetic analysis of multiple metrics using a metabolic cage system. Our results indicate, surprisingly, that the dual absence of T-bet and RORγt does not appreciably affect the susceptibility or severity of acute DSS colitis. These studies may provide a basis to uncover new biomarkers, disease mechanisms, and therapeutic targets in the setting of IBD.
