Back to the Republic of China as a doctor

Chapter 132 130. It's like looking for Mr. Fleming (please subscribe monthly pass)
Lin Wan looked at Jiang Lai, a little flustered, but also a little expectant. Jiang Lai...likes her?

But why?
But when she saw Jiang Lai's silence again, she thought about what happened the day before Jiang Jikai and Gu Ya's wedding, so she calmed herself down, then smiled, and continued eating wontons. The wontons wrapped in fresh shepherd's purse taste really good.

"I'll take you to school later." Jiang Lai spoke immediately after eating a poached egg.

"Okay, sorry to trouble you." Lin Wan agreed.

Jiang Lai shook his head and smiled, "It's fine."

In the end, both of them ate the wonton seriously, never mentioning what the stall owner just said.

……

It's night, Jiang Yuan.

Jiang Yunting looked at his youngest son, and then at the older son who was being ordered by the younger son to move a blackboard, then he opened his mouth helplessly, "Forget it, the brothers have a good relationship... that's all."

"Just put it here!" Jiang Jikai clapped his hands and set up the blackboard, "But you put such a blackboard in Dad's study, those who don't know will think you are going to class!"

Jiang Lai thought for a while, "It's no different from class."

Jiang Jikai: ... It's better to slip first!
"Brother, listen to it too, it has something to do with our family's future." Jiang Lai opened his mouth and left Jiang Jikai behind.

"Then just listen to Jikai." Jiang Yunting then spoke.

Jiang Jikai: ... No, I just want to sleep with my daughter-in-law.

Jiang Lai, on the other hand, started to draw a simple person on the blackboard freehand. Since he invited people like John to come with him, he had to explain something to them.

The development of medicine is of course inseparable from examination equipment. Blood-related examinations have been gradually improving since the introduction of microscopes, but organ examinations, except for X-rays, have not yet been seen.

What he wants is to tie this group of people to the chariot, and then try to support Huaxia in the ensuing war, that's all.If you want to tie others to the chariot, it is not enough to show kindness, and more importantly, the consistency of interests.

Not long after, Mark, Smith and John arrived, and brought another person, Mr. Hart from Hart Trading. John had greeted Jiang Lai in advance.

And Jiang Yunting also made people serve tea, so he closed the door and waited for Jiang to start.

"How is Mr. Smith feeling these days?" Jiang looked at Smith, as if he was not very energetic.

"I'm a little weak. I always felt hungry two days ago, but today...it seems to be much better." Smith thought for a while and answered seriously.

Jiang Lai nodded, "Get used to it, it's fine."

"That's right." Smith nodded.

"In this case, time is precious, so I will start." Jiang Lai took a chalk and pointed to the blackboard. There was only an outline and a two-dimensional drawing of the main organs of the human body.

"Gentlemen, have you ever thought about what it would be like if there were no wars in this world and more democracy and freedom in the future?" At the beginning, Jiang Lai asked a question.

In the world of later generations, the level of civilization is getting higher and higher, and it is much better than the current era. Of course, dirty and dirty things are also inevitable. At least... the life of the people is much better.

"Now, isn't there no war?" Smith was puzzled.

"The Japanese are holding me in the three eastern provinces of China." Jiang Jikai retorted.

Smith shrugged.

"Then, have you ever thought about how well developed medicine can increase the average life expectancy of human beings to 80 or even 90 years old?"

As a result, everyone in the room began to look at each other in blank dismay, let alone the average life expectancy increased to 80 years old?It is not bad to live to be 50 years old in this era.

"The existence of medicine, from the very beginning, is to serve human life and health." Jiang Lai continued immediately, "Whether it is Western medicine or Chinese medicine, it is the same. Everyone knows that when surgery first started, there were countless deaths."

"But until now, the death rate has gradually decreased, which is due to the progress of medicine."

"Whether it's medicine, equipment, or inspection equipment."

"If there is no war in the future world, people's democracy and freedom, medical progress, and human life expectancy will continue to increase...and in the process of increasing human life expectancy, there will be countless medicines, instruments, and equipment involved."

At this point, everyone nodded. Indeed, the emergence of X-ray machines has also created a number of companies.

"Then, what I want to do is to work together with you gentlemen to fight for human health in this process in the future."

Jiang Lai is not very interested in making money, but the people present here are all more interested in making money than him, so, to tie these people down, the interests are definitely the big ones.

"Besides, people will grow old one day. Who can guarantee that they will not get sick for a lifetime? No cancer?"

"Only the advancement of medicine can better protect the health of you gentlemen."

To this, Smith nodded in agreement. He is full of problems now, and he still wants to live longer.

As for John, his eyes are full of interest. His wife has already been hospitalized once. He knows too well that health is more important than many things.

Even Mr. Hart on the side was moved by Jiang Lai. He is in good health now, but there are other friends around him who have more or less problems.

"Let's look at this first. I roughly drew a person, including important tissues, organs and blood vessels." Jiang Lai pointed to the blackboard and explained, "At this stage, the inspection equipment we have is an X-ray machine. It can take pictures of the bones and other organs of the human body. I won’t talk about the principle, but the invention of the X-ray machine is right to make our medicine go a step further. It solves the situation that doctors cannot see the patient’s body lesions. , but ... it worked out, and it didn't quite work out."

"Some diseases cannot be displayed by X-ray machines at all, and the limitations are very large."

"Maybe you don't know where the limitations are, so let me tell you first." Jiang Lai continued, "The human body is an organic whole, divided into several systems, including the circulatory system, respiratory system, nervous system, motor system, and reproductive system. , urinary system, digestive system and endocrine system.”

……

"For example, diseases in blood vessels cannot be shown by X-rays."

"For another example, some tumors in the body whose density is close to that of normal tissue cannot be fully displayed by X-rays. For example, Ms. Dana was hospitalized before. If there is more advanced equipment...there is almost no possibility of misdiagnosis."

……

"So, drugs are a large category, and the development of chemical industry has accelerated the development of various drugs."

"As far as I know, there is a paper in the New England Journal of Medicine that is sufficient to accelerate the progress of human medicine, and it is now being left to mold in a corner."

……

"Everyone knows that sound is produced because of vibration."

So some people nodded and some shook their heads.

Jiang Lai: ...

"In the last century, Heinrich Rudolf Hertz discovered the existence of electromagnetic waves. To commemorate him, scientists use Hertz as a unit of measurement, that is, the number of periodic changes per second."

"At first glance, the sound has nothing to do with Hertz...but the sound is produced by vibration." Jiang Lai stretched out a loop of wool, tightened it, and then moved it. "Everyone thinks that this wool has just vibrated a few times. Second-rate?"

Everyone: Why do you feel like you are listening to a physics class?

The problem is, some people don't understand it at all.

"Well, let's be more direct. The sound waves with the upper limit frequency of human hearing (about 2 Hz) are called ultrasound, or ultrasound. About 20 years ago, the scientist Langevin made a sandwich ultrasonic transducer with natural piezoelectric quartz. Energizers, and used to detect submarines on the bottom of the sea.”

"Ultrasound, in different media, is produced and researched in different ways, expressed in terms of amplitude, or grayscale brightness, etc..."

"And this technology, if used to detect the human body..."

"Wait!" Jiang Jikai interrupted Jiang Lai, "Can't that detect submarines?"

"So, what I'm talking about is, if it's applied to the detection of the human body, what kind of performance will it be?" Jiang Lai said in a deep voice.

"I probably understand what Dr. Jiang means. You mean that ultrasound can also be used to detect the human body?" John said, "But as far as I know, there is no such technology at present."

"That's right, so we need to push it forward, just like looking for Mr. Fleming." Mark answered the question in a rare way. When he arrived at Jiang's house today, he was full of surprise and shock when he heard Jiang Lai's words.

He didn't expect that Jiang Lai's goal would be the health of all human beings!Unlike businessmen like Smith, he is a reporter. Although he also likes money, he pursues the truth more!

He was moved by Jiang Lai's vision, such a person is worthy of his cooperation.
