My biological clock

My biological clock
One year passed through quickly, I will be a sophomore after a long summer vacation. In last year, I met many new friends, new teachers, and learned many new things, but my biological clock is in a strange way. I always go to bed at 1 or 2 a.m., it is harmful to my liver. The Chinese medicine has a statement that our circulation of blood will through our liver from 11 p.m. to 1 a.m. But, we always played games, watched movies or wrote some paper in this period of time. I think I should adjust my life style; otherwise my liver will be bad.

many complex structures of heart

many complex structures of heart

We have learned many complex structures of heart. They are atrium, ventricle, innominate artery, left common carotid artery, left subclavian artery and so on. I think I can enjoy in the memory process, because these structures are essential for all of us to become a good and professional doctor. We have to know these parts and when we operate a surgery, we should use these information rapidly and fluently.

A biology project H. pylori

A biology project H. pylori

Recently, our biology teacher gave us a project to take a deeper look at the H. pylori. It is a bacterium that causes gastric cancer and gastric ulcer. The reason is that it can secrete three types of chemical CagA, VacA and Urease. CagA can activate IL-8 and cause inflammation and finally cause gastric cancer. VacA can cause apoptosis and trigger cell damage and T cell inhibition. Urease can trigger gastric ulcer and eventually lead to gastric cancer.
Although these complex mechanism made me upset, these are important in clinical treatment for a doctor. So I have to remember all these processes and teacher will give us a final exam.

endless tests

Final exams are coming soon.
We have many subjects to read. There is English, Chinese, chemistry, biology and so on. I think I should stay up late to prepare these endless tests. I want summer vacation, air-conditioners, ice cream and so forth. If I successfully passed all of these subjects, an endless summer vacation will come to me.

A Good Lesson

My mother and I both like shopping. Last Sunday, we went shopping at the night market because there was a big sale. We walked there since it was not far away. By the time we arrived, the street was already crowded with shoppers looking for bargains. Despite the great crowds of people, we felt excited about shopping in such a place.

We came home loaded with things we had bought. My father complained that we should not buy things on impulse. Both of us were so happy about our new clothes that we ignored what he said. However, when we tried on the clothes the next day, we found that not all of the clothes fit. We were both upset about it, but there was nothing we could do. We learned a good lesson about buying things.

There is a speed limit

This morning I woke up very early; I did not know what to do. I saw my watch it is four a.m. I opened my door quietly and went out of my home with the key of my father’s car. I drove my father’s Benz with excitation. Because it is four a.m., there is no car on the road. I drove the car faster and faster, suddenly when I saw a sign said, “There is a speed limit.” Then I saw my speed board it said 140 km per hour. Oh, no.

I think I should eat instant noodle for a period of time.
