Seeing that everyone looked at them strangely or sympathetically, Xiao Nan nodded, and then groaned slightly, and said: "The most common type of cor pulmonale is chronic hypoxic hemagic cor pulmonale, also known as obstructive emphysema heart disease, referred to as cor pulmonale, which refers to the increased pulmonary circulation resistance caused by chronic lesions in the lungs, thoracic cage or pulmonary artery, resulting in pulmonary hypertension and right ventricular hypertrophy, with or without right heart failure. ”

Hearing Xiao Nan's smooth words, many of the students next to him were stunned, thinking that Xiao Nan would not be able to answer, but they didn't expect that Xiao Nan would answer so fluently, and even Professor Li, who was originally displeased, looked a little better at this time.

If a student with good grades dozes off occasionally in class, this is still allowed!

Who knew that Xiaonan did not stop, and continued to say: "Generally, cor pulmonale is mostly caused by chronic bronchitis, obstructive emphysema, bronchiectasis, tuberculosis, bronchial asthma and pneumoconiosis, etc., which then cause right ventricular hypertrophy, and even develop into heart disease with right heart failure. Because the disease progresses slowly, often years or decades to develop into cor pulmonale, it is more common in older people. This is a systemic disease caused by cardiopulmonary dysfunction.

"Ah, okay, okay, it seems that Xiaonan's answer is good!" Seeing that Xiaonan still had the idea of continuing to speak, and seeing that he was about to help him finish today's class, Professor Li quickly interrupted and said, "Sit down, sit down, since you know, then if you want to doze off, continue, as long as it doesn't affect other students!"

Hearing the professor's words, Xiao Nan sat down in disdain, to be honest, this Professor Li is a good person, he really didn't mean to doze off!

Yang Qiong, who was sitting in front, was already stunned by the scene in front of her at this time, and the girl next to her also had a strange look on her face at this time.

This morning, it seemed that Xiaonan was strong and supported to listen, and finally waited for the end of class in the morning, and Xiaonan breathed a sigh of relief and walked out of the classroom with the flow of people.

But as soon as he walked out of the door, he felt countless strange eyes projected outside the door.

As if Xiaonan was slightly stunned, and before he could come back to his senses, he heard a familiar voice not far away: "Xiaonan!"

Looking at him, a slender figure stood in the sunlight not far away, beckoning gently to him.

Squinting his eyes slightly, it seemed that Xiao Nan could see the beautiful smile on the bright and amazing face in the sun.

"Kim Yeon-so?!"

"Yi Xiaonan, you're finally out of class, I've been waiting for you for a while, let's go and eat together!" Kim Yanxiu stepped forward with a smile, her hair flowing lightly in the sun, which was amazing.

At this time, Yang Qiong was coming out from behind with her friend, and looked at Jin Yanxiu, who was walking with Yi Xiaonan closely, and her face, which was originally a little unsightly, instantly turned blue, and her eyes were full of disbelief.

"Hehe, I came here to wait for Yi Xiaonan to eat, this is not like an ordinary relationship as someone said!" Ren Zeyu's voice sounded behind Yang Qiong.

"Yes, it seems that Xiaonan, this kid really can't see it, this time it's really earning face for our clinical medical school, this is Jin Yanxiu!" Wu Bin's voice sounded with envy and excitement.

While speaking, the two boys glanced at Yang Qiong, who was pale, with a blue face, and then walked away quickly, leaving only Yang Qiong standing there, her face extremely ugly.

Sitting in a quiet corner of the cafeteria, Xiao Nan looked at an envelope pushed by Kim Yanxiu, and after being slightly stunned, he smiled: "For me?"

"I told my mother that you did us a great favor this time, which is a small reward, and she hopes you don't refuse!" Kim Yeon-so nodded seriously.

As if Xiaonan glanced at the envelope, stretched out his hand and pushed it back, shook his head and smiled: "I said no, you also helped me last time, and you also sent me two sets of clothes, so it can be regarded as my payment!"

"No, these are two different things, you don't know how much you helped me and my mother this time!"

Jin Yanxiu insisted on pushing the envelope over again, looked at Yi Xiaonan gratefully, and said: "You have at least helped our Yaxiu Group recover more than a billion losses this time, but more importantly, you helped my mother defeat the conspiracy of my uncles and keep the position of the president of the Greater China Region, so that my mother and I don't have to whisper in front of my uncles and them in the future!"

My mother said that you had done us so much that you should not have used this money to thank you, but she said that if you need anything in the future, just ask us and my mother will try to help you!"

Listening to Jin Yanxiu's words, Xiao Nan shook his head with a light smile and said, "I really don't need to, I said that this is a favor for you, and you and your mother don't have to remember anything I owe you in the future!"

Seeing that Xiao Nan still refused, Jin Yanxiu was not surprised, but the smile on her face became richer and more serious: "Xiao Nan, you listen to me and I know you don't want to accept it, but I just want to tell you, I want you to accept it!"

"Really, I want you to take it, we are friends, and we don't need anything else to help each other, but this money is what my mother asked me to give you, not me, and you need this money, and your father needs this money and you deserve it, so I hope you don't refuse!"

"Maybe my mother or I will ask you for help in the future, and you will definitely continue to help. But if you don't accept it, if something really happens, I really can't be embarrassed to ask you for help!

Looking at the hope and sincere words in Jin Yanxiu's clear eyes, Xiao Nan's eyebrows were slightly raised, and after a little silence, he nodded, took the envelope, and said with a smile: "Okay, I'll take it, thank you, and please thank your mother for me!"

"Okay!" Seeing that Xiaonan finally agreed to accept it, a bright smile on Kim Yeon-so's face instantly bloomed.

Back in the bedroom, Yi Xiaonan opened the envelope and saw a check for 100,000 yuan inside, not surprised; looking at this check that could improve the biggest dilemma in front of him, Xiao Nan took a breath gently, carefully put the check under the pillow, closed his eyes, and showed a rare trace of relief on his face.

Counting, this should be the most relaxed time for him in the past two years, the huge pressure that has been pressing on his body, under the effect of this 100,000 yuan, although it is not said to be completely let go, but at least he no longer has the urgency of every moment, and the relaxed feeling that he can't give away if he wants to breathe a sigh of relief.

Anyway, with this 100,000 yuan, Dad's medical expenses are not short for the time being, Xiaobei's food expenses can be more, and he doesn't have to work so hard, he has more time to do what he needs to do!
