"That's meaningless," Su Yun said. "Humans have 46 chromosomes, and gorillas have 48. There's no 47 chromosomes left … Huh? Why are we talking about this? "
"It's all because of you." Zheng Ren used a sterile glove to fiddle with the hair on the soles of the patient's feet, pondering how to solve this problem.
"It has nothing to do with reproductive isolation or genetic changes. I think it's hair migration." Zheng Ren twirled the hair on the soles of the feet with his hands and gently placed it on his fingers. "It's embedded in the outermost layer of the skin. As it continues to walk deeper, it gradually stimulates the nerve endings in the thicker layer of skin on the feet."
"Boss Zheng, please speak slowly." Zhou Litao did not hear clearly. He asked immediately if he did not understand.
"Why can't I understand what you're saying?" Su Yun seemed to have forgotten the smell of the patient's sweaty feet. He moved closer to Zheng Ren's fingers and looked at the extremely thin hair seriously. "It's true. I remember that article. It was published by a doctor in Brazil."
"Brother Yun, what is it?" Zhou Litao asked.
"There's a similar case report in the Visual Journal of Emergency Medicine. I think the hair quality of white people is relatively soft, so the possibility of hair migration is not high," Su Yun said. Su Yun said, "Normally speaking, it's more likely to appear among Asians with more hair and harder hair."
"But this hair … is a little soft."
Su Yun moved closer and looked at the strand of hair on Zheng Ren's finger seriously.
Zheng Ren was very worried that Su Yun would faint from the smell like Lin Yuan. After looking for a while, his eyes were already filled with tears.
It was not deep love, but the sour smell was too strong.
"Boss Zheng, is that it?" Zhou Litao looked at the hair on the soles of his feet in confusion. It was really difficult to connect the intense pain of the patient with it.
Zheng Ren then gently touched the root of the hair with his other hand.
"Ouch …" The patient immediately cried out in pain.
"Does it hurt that much?" Su Yun asked.
"It hurts … It's not that painful, but I'm used to it," the patient said with some fear. "As long as it's a little strong, it hurts as soon as I touch it. I … I'm not faking it."
"I know. The hair penetrated the stratum corneum and extended deep into the soles of the feet, touching the peripheral nerves," Zheng Ren said softly. "Look at his state of pain. Consider the position of the hair entering a little deeper."
"Use tweezers, I'll do it," Su Yun said.
"Don't," Zheng Ren said. "Take it under the microscope."
"Are you making a mountain out of a molehill?" Su Yun asked, puzzled.
"I've also read the article in the Visual Journal of Emergency Medicine. Since the patient is Caucasian, his hair is relatively soft, and he can be removed with a pair of forceps. I think we have to be careful. Once part of the hair is left in the deep layer, it will be very troublesome to take it out. Even if you cut it open, you won't be able to find it. "
Zheng Ren expressed his true thoughts very seriously.
The patient sat on the consultation bed and listened in a daze. Even now, he was still thinking about the reproductive isolation between humans and gorillas that he had just said. He had not recovered from the shock.
What was going on? His heel was hurting, so why was he talking about it so far?
"Alright, put on your shoes and follow me to the treatment room," Zheng Ren said.
"Doctor, where are we going?" The patient was stunned for a moment and asked in a low voice.
"The hair fell off and was stepped on by you. Later, it penetrated the stratum corneum and entered the position of the peripheral nerves," Zheng Ren said. "You need to 'pull' that hair out to cure your illness."
The patient still did not understand. He felt that the junior doctor in front of him was a little young, but he had a strong aura, the kind that could not be questioned.
He put on his shoes and tiptoed to follow Zheng Ren to the treatment room.
"Lin Yuan, go to the operating room and bring me my microscope," Zheng Ren said. "If there's … Forget it, you contact Yiren. I still have to … I'll do it myself."
Zheng Ren probably felt that it was too troublesome to explain a little bit, so he said a few more words to the patient and turned to leave.
Lin Yuan watched Zheng Ren leave in surprise. He went to find the surgical equipment and asked in a low voice, "Brother Yun, what is Boss Zheng going to do?"
"He's making a mountain out of a molehill," Su Yun said. "Just pull it out with tweezers. He insisted on cutting the stratum corneum under the microscope. How thick do you think the hair is? "
"60 to 90 microns," Lin Yuan said without thinking.
"That's right, less than one-tenth of a millimeter. Your Boss Zheng is mighty. He wants to perform a surgery without bleeding. "No matter what Su Yun said, he would not say it properly. The sarcastic tone in his mouth was thick.
"Brother Yun, without bleeding?"
"Cut the stratum corneum. The stratum corneum at the soles of the feet is slightly thicker, probably about 100 microns. Then, go to the germinal layer, where the adhesion between the body tissue and the hair is not as serious. Then, pull the hair out. "
"…"
Lin Yuan glanced at the patient. It was just a patient who came to the emergency department for treatment. No wonder Brother Yun said that Boss Zheng was making a mountain out of a molehill.
The patient sat quietly on the bed in the treatment room and waited. Soon, he saw the young doctor return with a metal surgical box.
When he put on the surgical microscope, opened the box and took out the small microsurgical equipment, the patient's eyes were fixed on Zheng Ren, who was full of technology. There were countless questions in his heart.
Before he could ask, he heard Zheng Ren say, "This is the black line in the skin. It needs to be identified with the migration of parasites.
"If it's a parasite on the epidermis, there won't be fixed pain and the itch will be very strong. With this experience, you'll know what to do next time you encounter a similar situation. "
As he spoke, the patient saw Zheng Ren install a small blade on the handle of the scalpel. It was as small as a child's toy. However, the blade reflected a few rays of cold light, which made him feel a little afraid.
Although he was a little afraid, he comforted himself in his heart.
It was okay, it was okay. No matter what, anesthesia was needed. He just did not know how thin the needle was to be used to anesthetize such a small scalpel.
No! Why did he not see the anesthetic needle? And! There was no anesthetic!
The patient was stunned. Before he could understand what was happening, Zheng Ren had already put the scalpel aside and picked up a pair of tweezers.
"Doctor, don't you need anesthesia?" the patient asked nervously.
"It's done. No anesthesia," Zheng Ren said lightly, then looked at the hair that had just been removed under the light.
"This is …"
"You walked barefoot at home and stepped on the hair. This hair drilled into the soles of your feet and pierced in like a needle. " Zheng Ren smiled and twisted the hair onto a piece of sterile gauze, then handed the sterile gauze to the patient.
