Falling behind at the start, the first surgery shocked the world.

All eyes were on Xia Tian.

Han Meiji raised an eyebrow.

"What kind of poisoning?"

Xia Tian analyzed, "In the early stages of Alzheimer's disease, there are indeed changes in mood or personality. A kind and amiable old man can turn into a selfish and self-serving person. There are cases like this."

"But the main symptom of Alzheimer's disease is forgetfulness."

"The personality change occurred later."

Xia Tian turned her gaze to her son and asked.

Has the elderly man ever experienced forgetfulness?

After a moment of contemplation, the son shook his head.

"no."

"He has a very good memory. He has taught so many students over the years, and he can remember the names of 80% of them. He also remembers clearly what to do every day. His memory is even better than mine."

Han Meiji crossed her arms and said with a cold expression.

"Premature memory decline is one of the symptoms, but it does not mean that everyone will experience it. A survey once found that 98% of Alzheimer's patients experienced premature memory decline first."

"However, five percent of patients will experience personality changes, but their memory will not be affected."

"So, it's still possible that Alzheimer's disease exists."

Xia Tian glanced at Han Meiji.

This person is very persistent in sticking to their own opinions.

A doctor who enjoys in-depth research will be a good doctor.

Xia Tian smiled and said, "Dr. Han is right, that's a possibility, but I'm thinking of another possibility."

"What?" Han Meiji asked.

Zhang Ming, Wang Xiaobei, and the others all turned their attention to Xia Tian.

Under the spotlight.

Summer uttered three words: "Cobalt poisoning."

"Cobalt caused nerve poisoning, which changed the old man's personality."

Cobalt, element symbol Co, is a silvery-white ferromagnetic metal with a slightly pinkish-white surface. Due to its physical and chemical properties, cobalt is an important raw material for the production of heat-resistant alloys, hard alloys, magnetic alloys, and various cobalt salts.

Cobalt metal has a wide range of applications in electroplating, glassmaking, dyeing, and medical treatment.

Upon hearing the words "cobalt poisoning," the group was stunned.

Wang Xiaobei blurted out, "What's cobalt?"

Han Meiji said softly.

"A type of heavy metal."

She turned to look at her son and asked.

"Has the elderly man had a hip replacement, a prosthetic limb, or metal teeth?"

Because of its hardness, cobalt alloy is known in medicine as medical stainless steel. Some braces and nails use cobalt alloy, including braces which contain a large amount of cobalt, and intramedullary nails.

Cobalt alloys are also commonly used in artificial joints.

Faced with Han Meiji's question, the son was stunned for a long time before speaking.

"My dad has a few porcelain veneers, which he got done at a small clinic a few years ago. I suggested he go to a big hospital, but he said it was too expensive and he went to the small clinic himself. It turned out quite well, and they haven't broken down all these years."

"Could it be because of the porcelain veneers?"

Summer crossed her arms, leaned against the table, and nodded.

There are many types of porcelain veneers.

"One type of porcelain crown is made of cobalt alloy."

"Cobalt alloys are inexpensive and are generally used more in small clinics."

Having analyzed the situation to this point, we can find out what illness the old man has by having him examined.

Zhang Ming said to the nurse.

"Get the old man checked for heavy metal poisoning."

A blood test is required for the examination.

Normally, it's the nurses who draw blood, but when the nurse glanced at the old man, her eyes were full of disdain.

He pursed his lips and said.

"I don't want to go."

Zhang Ming was taken aback and looked at Han Meiji.

Han Meiji had a cold expression on her face. Although she didn't say anything, it was clear from her expression that she was cold.

Let me go?

Dream on!

Finally, Zhang Ming's gaze fell on Xia Tian. Xia Tian's face darkened, and she said quietly, "When I was stitching him up, the old man touched my arm..."

The baby was bullied.

The baby is so upset!

Zhang Ming's eyes widened, and his expression changed instantly.

"Goodness."

"It's one thing to bully nurses, but they're not even sparing doctors!!!"

Han Meiji said coldly, "If it really is cobalt poisoning, it means the old man is a good person; he's just sick. Please look at him with the eyes of a patient."

Summer glanced at her.

"Then you go smoke?"

snort!

Han Meiji gave a soft snort and turned her head to the other side.

Nobody wanted to go.

An old pervert who has had sexual relations with both men and women, even if he is addicted, it is understandable that he is a patient, but being touched all over is still disgusting.

"I'll go."

Wang Xiaobei stepped forward, grinning, "It's just a blood test."

"let me."

Wang Xiaobei strode towards the old man, only to be slapped a few times by his son. The old man was sobbing when he saw someone walking towards him.

His eyes immediately lit up.

That look in his eyes was like a wolf seeing meat, or a dog seeing excrement.

Sparkling!

"Oh, another young man."

"There are quite a few young men at the provincial hospital."

"Come here and let Grandpa touch you."

Just as the old man was about to reach out, Wang Xiaobei pulled off his mask and grinned at him.

"Hehe, am I handsome?"

The old man was startled and quickly withdrew his hand, which was halfway out...
