September 12.

Blue Sky Military University.

Military Medical College, major in exemption studies.

Instructor Qi Zhao walked into the classroom and gave the students a medical exemption class.

He opened the PowerPoint with his computer and said, "Before the official class, I will check your learning results this week." "

At present, freshmen, first-year students, and first-year Ph.D. freshmen are all undergoing hardcore new training.

The students in the classroom are all sophomore military medical students.

They ended their summer vacation on August 25.

It has been 20 days since they returned to school, and life is already on track.

With the PPT being opened.

On the six touchable displays in the classroom, several questions are displayed at the same time.

[1.The ligand molecule obtained by LFA-2 is (?) ):A.LFA-1,B.VLA-1,C.ICAM-1,D.CD2,E.LFA-3】

[2.The phenotype of YBT cells is (?) ):A.CD4+CD8+B.CD4+CD8-,C.CD4-CD8+D.CD4

[3. The molecule obtained by macrophages and Th-cell to present antigen peptides is (?) ): A. MHC-I molecules, B. MHC-11 molecules, C. MHC-Sichuan molecules]

[4. During the humoral immunity response, the first signal of ThO cell activation is (?) ): A. MHC-11 molecule interaction with CD8 molecule, B. MHC-I molecule interaction with CD8 molecule, C. MHC-11 molecule-antigen peptide interaction with TCR, D. IL-2 interaction with IL-2 receptor]

【......】

After the question.

Qi Zhao looked at everyone in the audience and asked, "Who will come to the first question?" "

Brush brush brush!

The students all raised their hands and wanted to answer the questions.

See this scene.

Qi Zhao smiled.

The classroom of the Blue Sky Military University is always so active!

He randomly selected several students to answer the questions.

The selected students easily answered the questions correctly.

Obviously, these students were listening carefully to the lecture when they were in class.

Qi Zhao nodded and said, "Students, you did very well in the quiz just now.

In the past, I took our courses according to the syllabus of "Medical Exemption from Military Service".

From this lesson, I began to use PPT to give lectures to everyone.

Okay, now for class."

The voice fell.

The students' eyes lit up.

To be honest, exemption from military service is a relatively boring course.

If you use PPT to lecture, it will be slightly more interesting.

Qi Zhao said while manipulating the PPT: "In today's lesson, I will introduce you to the important role in the innate immunity system team that can help resist viral infections - natural killer cells (Natura1-killer-ce11, NK-ce11).

NK cells, you can think of it as a gendarmerie of the exempt system.

It fights on the first line of defense for health all year round.

Especially on the battlefield of monitoring and destroying cancer cells.

NK cells always lead the way and fight bravely.

They use a rolling drift, stop, and leave strategy to leave the bloodstream, enter the tissue at the site of infection, and proliferate rapidly.

After NK cells arrive at the battlefield, they can release cytokines such as IFN- to help defense, and when NK cells are activated, they can release a larger amount of cytokines and have a better killing effect.

Simply put, it is the most important fighter in the body responsible for killing abnormal cells such as aging cells, virus-infected cells, and tumor cells.

When killing tumor cells, NK cells have the fastest start time and the most types of enemies, and they only need to receive some molecular change signals from cancer cells and can immediately enter the battle.

Therefore, NK cells are hailed by the medical community as the first line of defense against cancer.

It exercises its killing function by forcing infected cells to commit suicide.

Powerful NK cells can always quickly find aging cells, cancer cells, viruses, etc.

And use its ultimate weapon, perforin, to punch holes in target cells, and after transporting suicide enzymes into target cells, the enemy will cleave and die..."

Originally boring course.

At this moment, under Qi Zhao's in-depth and simple and vivid and interesting narration.

The students listened with gusto.

The PPT on the big screen, the pictures that appear are carefully selected by Qi Zhao, and a "noun explanation" section has also been set up.

The ratio of pictures and text is just right.

Not only can it arouse students' interest during preview, but it can also facilitate students to find the key points when reviewing.

For example, when introducing various exempt cells.

Qi Zhao described them as Marvel heroes.

Each cell has its own special function, but various immune cells also cooperate with each other. (Read violent novels, just go to Feilu Fiction Network!) )

In the case of macrophages and T cells, when Mycobacterium tuberculosis infects macrophages, T cells will come to help attack.

When T cells and B cells obtain a surname-free response, the phenomenon of "combinatorial attack" is also widespread.

......

Time passes slowly.

The students listened carefully and learned a lot.

Above the classroom.

Qi Zhao turned the theory class into a discussion class and gave the students a very challenging topic.

The topic is to view the hospital's blood routine test report.

He distributed a stack of test reports to the students.

Watch and watch.

The students exclaimed.

"'Didn't that read that right? I actually understood this report sheet! "

"Isn't it a basic operation to understand the test report sheet? What's the fuss? "

"I mean, I can tell at a glance which pathogen I have and whether I need antibiotics."

"I understand too. In the past, I only thought that learning free military service was boring, but I didn't expect to learn a lot of knowledge from this course. "

"For the first time since I came into contact with the course "Medical Exemption Studies", I found it so interesting!"

......

Discussion room.

The mood of the students is very good.

Originally in their eyes.

Qi Zhao is an ordinary instructor and lectures decently.

But today...

Qi Zhao instructors, the lectures are exquisite, easy to understand, in-depth and easy to understand, and good at examples.

In addition, his PPT is unique, it's just like changing a person!

National famous teacher, is it just that?

......

At the same time.

All the students who were attending classes at the entire Blue Sky Military University noticed the change in the classroom.

In their opinion.

The classroom education ability of teachers and teaching officers has clearly reached a new level.

In itself, students learn seriously.

Now, the instructors and instructors have improved a lot.

The combination of the two.

As students learn the course, they become more and more comfortable!

In fact......

What they don't know is.

All the instructors and instructors of the Blue Sky Military University have the "aura of famous teacher education", and the effect of teaching in class is doubled.

Other words.

Every student can get an unprecedented quality education in the classroom!

At the same time, teachers preach, teach, and solve confusion, and they have the role of sorting out their own knowledge and improving their professional level.

The more they attend class, the stronger their teaching ability becomes.

The stronger the teaching ability, the greater the progress of the students.

It coincides with Teachers' Day on September 12.

Blue Sky students, send their sincerest wishes to all teachers.

"The three-foot podium is the national fortune, and the soul of the people is forged by candles throughout his life."

"Three thousand gardens of peach and plum sown in spring, fruitful in autumn."
