Doctor: It's reasonable to perform surgery on yourself.

"By the way, Sister Susu, what did you put in the patient's mouth?"

"A note."

"Note?"

"Yes. I just wrote down the three happy events that Director Xiao mentioned, promotion, wealth, and death of wife."

Liu Susu sighed.

She has worked in the emergency department for so many years, and her experience is definitely not comparable to Wang Fan's.

In her opinion, the couple's relationship may have been very long, maybe since junior high school or high school.

It's just that now, the man has become the director, surrounded by young and beautiful female subordinates, nurses, and young and energetic graduate students and interns.

Looking at his wife who worked hard with him, he suddenly couldn't stand the white hair and drooping wrinkles on her temples.

But he probably forgot.

During his graduate and doctoral studies when he had almost no income, and the most difficult and tiring seven or eight years as a resident and attending physician, it was this thorn in his eye who stood between him and other women.

…

After handling this matter, Xu Qiu completed two more surgeries in the afternoon.

Before leaving get off work, he habitually glanced at the inpatients.

One patient was admitted in the afternoon, and his hemoglobin reached more than 200, with a red "Critical" in front of him.

It has reached a critical value.

Then he saw the first doctor and had a physical examination.

It was the pancreatitis patient that Liu Susu asked Wang Fan to admit.

First of all.

No diarrhea, nausea, or vomiting.

Intestinal colic can be ruled out directly.

Tenderness under the xiphoid process after eating, persistent abdominal pain, relief when sitting... textbook-level signs of pancreatitis.

Wang Fan's diagnosis is that pancreatitis is no problem.

Moreover, the laboratory department called to remind that the patient's blood samples are generally white, which means that the blood drawn is lipemia.

Serum lipase, amylase, etc. have reached about four times the normal value.

In theory, hyperlipidemia pancreatitis can be diagnosed.

However, Wang Fan also had experience from the daily scolding of many seniors in the emergency department. He did several more tests and found that the patient's blood sugar was also very high, and the urine sugar reached "+++".

Therefore, in the final diagnosis, he added a question mark after "hyperlipidemia pancreatitis" and "diabetic ketoacidosis".

It is estimated that we have to wait for the gastroenterology department to come for a joint consultation and further discussion.

After reading the patient's various reports, Xu Qiu shook his head.

In this case, the patient may not be able to delay too long.

He immediately called Wang Fan.

"Brother Xu?"

There was a sound of water coming from Wang Fan's side, "I just pulled out the catheter of a prostitute, and she sprayed my hand. Her urinary tract irritation symptoms are serious enough."

"..."

After a moment of silence, Xu Qiu asked, "Patient in bed 27, have you made an appointment for a consultation?"

"Oh, is it the pancreatitis patient admitted today? Yes, I'm not sure if it's ketoacidosis or hyperlipidemia, wait for the gastroenterology department to come and check it."

"First, prescribe 5,000 ml of sodium chloride, three-way fast drip." Xu Qiu said nonsense.

Wang Fan quickly wiped his hands and ran to the ward: "Okay, I'll arrange it right away."

He thought for a moment and said, "Brother Xu, I plan to check the blood gas to see if it is ketoacidosis."

"No need."

Xu Qiu gave an explanation: "The patient's indicators have indeed reached the criteria for ketosis.

But, it is not ketoacidosis yet.

His carbon dioxide is 20.8mmol/L, not at the stage of checking blood gas.

In addition...

Although ketoacidosis can also cause pancreatitis.

However, this type of pancreatitis is ketone bodies stimulating pancreatic exudation, and the abdominal pain is not obvious.

And its pathogenesis is generally due to absolute insulin deficiency, nausea and vomiting, and inability to eat.

However, this patient has obvious abdominal pain, but no nausea and vomiting.

In addition, half of the tube of lipemia, blood lipid metabolism is abnormal, hurry up and arrange insulin and plasma exchange."

After listening, Wang Fan was shocked.

He was still wondering whether this pancreatitis was ketone bodies stimulating exudation or abnormal blood lipids.

As a result, Xu Qiu pointed out the difference in details in just a few words, and it was the final word!

These experiences are not in the textbooks. Without more than ten years of clinical practice and slow summary, it is not necessarily possible to integrate them!

"Got it, Brother Xu, I will arrange it right away!"

Wang Fan sniffed his hand.

Well, it is finally gone.

His status has risen a lot now.

It was really miserable when I was digging feces before.

There is also gas gangrene.

Even if I wear three or four layers of gloves, the smell will not go away for several days.

Do you understand the gold content of the champion of the famous knife competition?

Who dares to let him be a dung boy!

...

...

Five o'clock in the afternoon.

Xu Qiu left work early and rushed to the Linhai University Research Institute.

With money and equipment, he was completely free.

All projects started at the same time, and the electricity consumption of the institute increased by more than a hundred times.

And experts such as Yang Chenxi and Ren Chao, under the guidance of Xu Qiu's seemingly inexhaustible inspiration, almost always maintained full-speed research and development progress.

Today, this batch of artificial blood vessels is moving deeper into the mechanism of bionic design.

The natural arterial wall is actually divided into three layers: outer, middle and inner.

The inner layer is mainly a single layer of endothelial cells.

It is anchored to a thin basal layer composed of type IV collagen, fibronectin and proteoglycans.

The function is to maintain blood vessels and control the diffusion of molecules through the wall by providing an anti-thrombotic surface.

The middle layer is composed of smooth muscle cells organized circumferentially, mainly composed of elastin and collagen sheets.

It has variable thickness, and the range of thickness change is proportional to the wall shear stress at the location of the blood vessel.

There is also an outer membrane on the outside, which connects the blood vessels to other tissues and provides structural support.

These three layers are actually just the basic structure of natural blood vessels.

After all, who can't make three layers of membranes?

Many important components that determine the physical properties of tissues have stumped countless scientific researchers, and even artificial blood vessel giants McCoy and Terumo have been deterred.

For example, the extracellular matrix.

The functions of this thing have been initially explored to provide structural support, withstand mechanical stress, regulate cell proliferation and differentiation, regulate growth factors, and promote vascular flexibility, etc.

Human-made blood vessels will never be able to do these.

We can only use structures, excellent designs, and release sustained-release drugs to get as close as possible, or even replace the functions of these important components.

This is the real shackle that plagues the entire industry to go deeper into the 6mm restricted area.

But now,

As the research and development is heating up, all the people involved in the research have begun to believe that Xu Qiu's solution may really solve the key problem that has plagued artificial blood vessels for decades!

At this time.

In the office, cups of boiled water are steaming.

Bang.

The door was gently pushed open, and the white steam was blown away.

Although his movements were restrained enough, who could tell that the excitement of the person pushing the door was about to be suppressed.
