There is no need to be too normal to be a doctor

In fact, this expo is very comprehensive.

Many devices can be tried.

Therefore, there is no problem with Davis' request at all.

In particular, this kind of photodynamic therapy is basically non-invasive.

This is similar to some common LED photodynamic therapy devices and those red and blue lights on the market.

Of course, there are still differences. After all, this instrument is not just for skin beauty.

Instead, special wavelengths of light are used to treat tissues.

Moreover, the greatest value of the third-generation photosensitizer lies in its specificity.

The instrument in Chen Gong's hand can completely kill tumor cells in the liver, stomach and other parts of the body.

As for why Davis is so impatient, there is actually a reason.

Firstly, because of Tracy's situation, after the age of forty-five, there will definitely be an unprecedented turning point, which may lead to the induction of intracranial vascular and other diseases.

And Trish can't delay any longer. Using radionuclide therapy can indeed effectively suppress the development, but... this kind of therapy will also cause some irreversible damage and have strong side effects on facial skin.

Even though Trish has gotten used to the bright red spots on her face over the years, it doesn't mean that she wants these tissues to fester and proliferate like demons.

Now seeing the third generation of photosensitizers coming out, Davis can be said to be extremely excited!

He now wants to try out the effect of this!

In addition, Davis is not worried about safety issues.

After all, he knew very well that all drugs and devices he wanted to submit to this platform had basically undergone special domestic approval.

Although it has not yet come out, it does not mean that there are safety issues.

not to mention……

The name of Chen Gong's research project begins with the prefix "国".

Although many countries are still suspicious of China's equipment and medicines,... the world still has obvious trust in things prefixed with the prefix "国".

Davis and Tracy are experienced experts and scholars in the industry, and they know these things very well.

What's more, "Cell" has already cooperated with China a few years ago.

Therefore, the two of them have a relatively good understanding of the situation in China.

Moreover……

A photodynamic therapy device is not a drug or requires surgery?

How big can the side effects be?

…

Chen Gong heard this and had no reason to refuse. After all... they had instructions for trying it right here.

There were many experts, scholars and media people at the scene, all making some special attempts.

There are various instruments on site, including some special inspections.

Such as capsule endoscopy, new color Doppler ultrasound or MRI... and so on.

There are many people trying it!

These media are all media people from professional journals and newspapers. They all have special knowledge of some equipment and professional items in the industry.

Therefore, their attempt is also a new type of evaluation.

To be honest, Chen Gong was a little surprised by a magazine with global influence like "Cell".

Moreover, Davis and Tracy are obviously a living case.

Thinking of this, Chen Gong smiled and nodded, and said to the staff on the side:

"Prepare some equipment."

After finishing speaking, he turned to Tracy and said: "Professor Tracy, if it is convenient, I hope I can take a photo of you, is that okay?"

There is actually no special examination method for port wine stain.

The main reason is caused by the expansion of capillaries.

The effect of identifying port wine stains is also based on appearance.

The direct external manifestations of the proliferation and expansion of capillaries in the dermis are very intuitive.

For example, changes in the color or area of ​​port-wine stains, as well as the pain caused by port-wine stains, will all be abnormal.

These are the most common indicators currently used clinically.

Color, area, pain.

These three points basically cover the analysis of the effects before and after treatment of port wine stain.

After hearing Chen Gong's words, Tracy was very calm. To be honest... If it weren't for this large bright red mole, Tracy must be an attractive woman.

"Very happy!"

"But, I have a suggestion."

"Professor Chen, since we want to compare, it's better to be more thorough."

"We have improved all indicators and data and investigated everything that should be investigated."

"In other words, we regard this treatment as a clinical trial, and after the treatment is completed, a complete experimental report will be formed."

"Of course, I tell the truth. No matter what the effect is, I will seriously write a report and give feedback."

"Would you like that?"

Chen Gong smiled slightly: "I can't ask for it!"

“We’re at a time when we’re lacking publicity.”

"hehe……"

Hearing this, Tracy suddenly laughed: "Professor Chen, you are very confident. Your products have also given our patients confidence."

"So thank you for your generosity anyway."

"At the same time, forgive me, I must report today's treatment realistically."

Chen Gong nodded and smiled: "Okay, I will take you for evaluation."

At this time, Chen Gong quickly called a staff member over to conduct an on-site assessment of Tracy's situation.

This process is relatively lengthy.

But, it's all worth it.

Being able to produce a professional report from "Cell" is more valuable than any advertisement or publicity.

As a professional journal in the biological and medical fields in the industry, Cell can even be said to be at the leading level.

His audience is huge!

To be honest, Chen Gong was worried at first that no one would feel it.

hehe……

Now it seems that I am lucky.

It took nearly half an hour to collect and record Trish's situation completely.

Next comes the complete treatment process.

The first treatment takes one hour.

Because it is a facial treatment, Chen Gong chose a relatively gentle treatment when adjusting the photodynamic force. Even so, the addition of photosensitizer will make the effect more significant.

After everything was ready, at this time... some media people and experts were already coming around.

When they looked at the electronic screen above Chen Gong, it said "Third Generation Photosensitizer Photodynamic Therapy Device"...

They all stopped to watch.

The voices of people around him soon became louder and louder.

Tracy is currently undergoing treatment in a closed space, like a capsule room.

This is to protect the privacy of the experimenter, after all...

If someone wants to come for a test, whether it is a color ultrasound or an electrocardiogram, they need to take off their clothes.

This is unacceptable to many women.

Therefore, each platform area has a simple capsule room.

"Third-generation photosensitizer? It's unbelievable that China has actually developed it?"

"No way? I remember that in August last year, the German company Cisse had just perfected the second-generation photosensitizer."

"Yes, I clearly remember that the other company said at the press conference that the prospects of third-generation photosensitizers are full of hope, and that third-generation photosensitizers will completely change the current pattern of second-generation photosensitizers, because their Specificity will allow photodynamic therapy equipment to truly appear in hospitals."

"That's what Cisse said. Although there are many studies on photodynamic therapy, it still cannot be used as a mainstream medical treatment. What's more, Cisse said that the future of photodynamic therapy is not for beauty, but for cancer treatment. To be honest, this step is very difficult!"

"According to the theoretical analysis of biophotosensitivity effects by former Nobel Prize winner in biology Cameron Terrence, the third generation of photosensitizers will greatly increase the response of biological cells to light effects. In principle, if the specificity is met, Cancer treatment can really be achieved.”

"The key is that the third-generation photosensitizer is just a concept. No one has really studied it. Things that lack factual basis are not worth studying."

"Yes, the only definition of the third-generation photosensitizer is to increase the specificity of biological tissues. I don't know if this third-generation photosensitizer really has such an effect?"

…

There are a lot of discussions among people around. Even Ma Weimin, a layman, can improve his theoretical knowledge of photosensitizers and photodynamic therapy a lot after standing here and hearing the discussions from everyone around him!

This seems to be just an expo, but in fact it is more like a professional academic discussion.

After all, those who can be invited to participate in the conference must have rich professional qualities, have a pivotal position in the industry, and their own magazines are very influential.

Only then can we come to the venue on the first day, holding the right to vote, and experience this feast in person.

Everyone did not ask Chen Gong anxiously. Instead, under the guidance of the staff, they picked up the brochure and some information on the screen and read it carefully.

"Huh? Mr. Davis, are you here too?"

Davis's influence in the industry is not low. He is a professional and was a well-known entrepreneur in the United States in his early years. Most importantly, Davis's own investment in the field of photodynamics is not low.

His wife, Tracey, is also famous.

A female scientist suffering from port-wine nevus congenital hemangioma has a very recognizable face, but she can make a name for herself in professional journals with her sharp reviews.

Tracy has a nickname in the circle, and her name is relatively loud.

Davis smiled slightly: "Oh, hello, Mr. Hibbert!"

"My wife is inside undergoing experimental treatment."

"As you know, Tracy has special port-wine spots on her face. The third-generation photosensitizer is very effective, and she wants to try it."

After hearing Davis' words, everyone around him suddenly realized.

but……

Everyone is more expecting and surprised.

If professionals conduct personal evaluations, both the credibility and professional attributes will be greatly increased.

For a while, everyone waited patiently.

Chen Gong is not in a hurry about this.

Ask the staff to pour tea for everyone.

soon!

Time passes minute by minute.

Everyone was reluctant to leave, and more and more people came slowly, and the number of people gathered here suddenly increased.

When everyone learned that "Viper Tracy" was receiving treatment, they were reluctant to leave and wanted to see the latest results.

that's all.

An hour was neither long nor short, and it was almost noon.

The buffet restaurant on the second floor of the Convention and Exhibition Center has already started eating, but no one has left.

At this moment!

Chen Gong also realized the benefits of a strong country.

Because Chen Gong’s exhibition area is not far from the elevator.

This benefit is immediately apparent at this time.

When everyone was getting ready to have a meal or just come down for dinner, they all saw the media and experts gathered here.

Out of curiosity, I wanted to come and take a look.

that's all!

Unknowingly, there were more than a hundred people at the booth where Chen Gong was.

Everyone is waiting curiously.

Just at this time!

Ma Weimin couldn't help but become nervous. He looked at Chen Gong and asked in a low voice:

"Is there going to be no problem?"

Chen Gong smiled slightly: "It's just a bright red mole, there's no need to be nervous."

"If the third generation of photosensitizers can't even accomplish this, what future can we look forward to!"

"Director Ma, the real greatness of the third generation photosensitizer lies in its specific treatment of tumors!"

"This will be a new treatment direction after radiotherapy, chemotherapy, and targeted therapy for tumor treatment: photodynamic therapy!"

"Just wait patiently!"

At this moment!

"Beep beep beep..."

There was a sound, and soon... the door of the treatment room opened.

A woman came out of it, and everyone focused all their attention on her at this moment.

That’s right!

This is "Tracey the Viper."

A professional who was born with a "red birthmark" on his face.

When Tracy came out, Davis was the first to react.

"Oh my God!"

"Tracy!"

"Honey!"

"how are you feeling?"

At this time, Tracy was equally excited. After the treatment, she saw herself in the mirror for the first time.

The bright red mark, which looked like blood, began to fade after the first treatment, and many areas had turned pink.

This means that these dilated blood vessels have begun to shrink and the blood supply is decreasing!

This is not the most critical thing.

There are signs of contraction around the red birthmark, which is the shrinkage of the dilated blood vessels after they lose their blood supply.

These two points are what she can see!

The third point!

pain!

The feeling of pain is caused by the dilation and proliferation of blood vessels and the compression of nerves.

Trish spends every day in pain, and her strong will is the biggest driving force for this woman's success.

And this time!

He clearly felt that the pain was decreasing.

If there was a pain rating, Tracy felt that it had definitely reduced by one level.

"Davis, I...I...I seem to be really effective!"

As she spoke, Tracy's tears began to flow out.

Seeing this scene, everyone around them became excited!

Is it really a third-generation photosensitizer?

Chen Gong smiled slightly at this time: "Professor Tracy, I suggest you not to cry."

"Because... we still have things to do."

Tracy quickly wiped the tears from the corners of her eyes: "Yes!"

"That's right!"

"Professor Chen, let's start!"

Following the reactions of Tracy and Davis, everyone around them suddenly became excited.

Third generation photosensitizer!

Is this really a third-generation photosensitizer?

If it is a second-generation photosensitizer, it will certainly damage the original tissues and cells while destroying the proliferating blood vessels.

It was impossible to cry like this without feeling severe pain.

Moreover, the second generation photodynamic therapy device has obvious side effects.

This is basic common sense!

Could it be...

"The third generation of photosensitizers is born!"

I don’t know who suddenly said such a sentence, and all the onlookers at the scene became excited!

…
