"Can, can it be cured?"
Yong Hongzhong asked in surprise and joy. During this period, he was tortured mentally and physically by this unknown strange disease that made him dizzy when he squatted down. In order not to make others laugh, he kept deliberately standing and sitting upright.
But every night, when you lie down in bed to sleep, you may still feel nauseous or even vomit.
Li Ang nodded calmly, "Yes."
"Doctor Li, what disease does my husband have?"
Yong Hongzhong's personal servant on the side asked respectfully, and his title changed from "little man" to "doctor".
Benign paroxysmal positional vertigo.
In other words, otolithiasis.
Li Ang silently thought about the answer in his heart.
As vertebrates, the reason why humans can balance themselves during exercise is mainly because there are organs in the ears that regulate body balance.
This organ is composed of three tubes and two sacs. The three tubes refer to the anterior semicircular canal, posterior semicircular canal, and horizontal semicircular canal. They are responsible for sensing the angle of the head.
The two sacs refer to the saccule and the utricle.
In the structure of the two sacs, there are some calcium carbonate salt crystals, which look like small stones or chalk powder, so they are also called otoliths.
Otoliths are usually fixed in the two capsules, helping them to sense the acceleration of the head and transmit position signals to the central nervous system through nerves.
It is precisely because of the three tubes and two bags that humans can "perceive" the balance and gravity of their bodies, and will not fall down or feel like the world is spinning.
And if due to some special reasons, the otoliths in the two bags fall off, it will cause a chain reaction - the fallen otoliths will swim in the endolymph fluid of the inner ear,
When a person's head position changes, the otoliths will stimulate the hair cells of the semicircular canals, causing the semicircular canals to be exposed to wrong signals, causing intense dizziness in the human body.
Otolithiasis mostly occurs in middle-aged people, slightly more often in women. The cause may be head trauma, strenuous exercise, staying up late for a long time, or middle ear and inner ear surgery.
Just now, Li Ang first ruled out the possibility of Meniere's disease and migraine through physical examination and questioning.
Through the Dix-Hallpike displacement test, that is, holding Yong Hongzhong's head, guiding him to lie down quickly backwards, actively letting the otoliths touch the semicircular canals, inducing a dizziness reaction.
It was finally determined that he had posterior semicircular canal otolithiasis.
(Posterior semicircular canal otolithiasis, that is, the otoliths move to the position of the posterior semicircular canal. When this happens, the Dix-Hallpike displacement test will only cause nystagmus when the affected side turns the head and lies on the side. The healthy other side will
Nystagmus will not occur on one side. Nystagmus will occur on both sides with anterior semicircular canal otolithiasis)
Of course, these processes are not easy to tell everyone in front of you.
Do people rely on the stones in their ears to know their position?
This is a bit too incredible.
You must know that in Memory of Another World, doctors discovered otolithiasis in 1921, but it was not until 1980 that a doctor named John Epley realized that the cause of otolithiasis was the loss of otoliths, and used
Repositioning technique to treat patients with otolithiasis.
In the middle process, doctors usually cure otolithiasis by cutting off the vestibular ganglion - the consequence of this is that the patient will lose hearing and balance abilities.
Moreover, even after John Epley proposed that otolithiasis could be cured by repositioning techniques, his research results were not widely recognized. Instead, he was ostracized and ridiculed by his peers, and even faced legal charges for illegal medical practice.
Li Ang's mind was racing. It was difficult for him to convince the people in front of him and tell them that the reason why people can feel gravity and position changes is because there are stones in their ears.
Even if he is convinced, there is no evidence, and people will suspect that he secretly did something shocking like dissecting a corpse.
The medical level of Yu State was relatively backward compared with architecture, materials science, astronomy, etc.
This situation is partly because monks in the academy rarely get sick and have no motivation to promote development.
On the other hand, it is because the act of dissecting and studying human corpses was taboo in both the Sui and Yu dynasties - it was almost a demonic act.
Li Ang still remembers Pu Liuxuan's advice, that he must first be admitted to the imperial palace, only then can he have social status, have a foundation to establish himself, and have the right to speak and influence.
Doctors must protect themselves first before they can protect their patients.
In the blink of an eye, Li Ang had weaved a set of words that could be accepted by the people around him, and said without changing his face or heart: "Although there are many causes of vertigo, they are all virtual and real.
Deficiencies are mostly due to deficiency of qi and blood, insufficient marrow sea, and loss of clear orifice nourishment.
Brother Hongzhong has been studying too hard recently, using too much energy, coupled with his weak body and insufficient supply of qi and blood, which is why he is dizzy."
"I see."
Song Shaoyuan and others showed expressions like "Oh, so that's what it is like, um, I completely understand it now", and they all pursed their lips and nodded.
Qiu Feng felt something was wrong, frowned and looked at Li Ang, but hesitated to speak.
"Then...Doctor Li, do you want my husband to eat more meat?"
Yong Hongzhong's personal servant asked respectfully,
Li Ang shook his head and said: "Eating more absolutely cooked beef, mutton, and fish, and not drinking raw water is one thing.
On the other hand, it is necessary to use manual reset and assistance.
That is to say, rotate the head to let the qi and blood in the heart flow to the head and unblock the qi in the head.
A combination of the two methods can provide a complete cure.
Come, brother Hongzhong, sit down again."
Li Ang asked Yong Hongzhong to sit back on the table, held his head again, and turned his head 45 degrees to the left affected ear.
Then pull the head and guide Yong Hongzhong to lie down, with the head slightly extending out of the edge of the table, and the left affected ear facing down.
"Brother Hongzhong, look directly in front of you."
"The sun rises above me, and I feel dizzy."
"It's normal to faint. Don't worry, I've never failed this reset method."
"Then you, how many people have you cured?"
"Congratulations, you are the first."
Li Ang calmly observed Yong Hongzhong, who was lying on his back, until his dizziness and nystagmus disappeared.
Then turn Yong Hongzhong's head 45 degrees to the right, and observe the same for one minute until the dizziness and nystagmus disappear.
"The last step is to turn your head and torso to the right together. Yes, it means lying on your side."
Li Ang asked Yong Hongzhong to lie on his right side and maintain the position for a minute. Finally, he helped Yong Hongzhong up and said, "Now, sit up and don't move, and concentrate on your breathing."
Yong Hongzhong closed his eyes and sat still. It was not until 5 minutes later that Li Ang asked him to open his eyes and said, "Okay, it's done."
Yong Hongzhong stammered: "Is this good?"
"Didn't you get dizzy when you lowered your head before?"
Li Ang said calmly: "Try again now."
Yong Hongzhong carefully got down from the table with the support of his personal servant.
Under the gaze of everyone around him, he slowly bent down and lowered his head, and said in great shock: "No, I'm not fainting anymore."
"Oh——"
"Can you cure a disease just by turning your head? Is there such a thing?"
"Incredible..."
Song Shaoyuan listened to the noisy people around him and stood proudly next to Li Ang.
The corners of the mouths of Ji Linlang and other students from Zhenzhou were slightly raised, revealing a proud smile.
Qiu Feng, the daughter of the imperial doctor, pursed her lips tightly and nodded in admiration. At the same time, a trace of doubt, stubbornness and unwillingness flashed in her eyes.
"Thank you, thank you Brother Risheng."
Yong Hongzhong excitedly thanked Li Ang. Li Ang waved his hand and said casually: "We are all classmates, don't worry about it."
"No, that's not possible. A gentleman must repay his kindness."
Yong Hongzhong couldn't help but take off a flawless white jade pendant carved into a fish shape from his waist, forced it into Li Ang's hand, and patted the back of Li Ang's hand gratefully.
"Brother Hongzhong, you're welcome."
Li Ang showed an awkward yet polite business smile, and his ears keenly caught the chubby student in the crowd muttering to himself, "Wow, Khotan nephrite..."
Khotan nephrite? Is it valuable?
Li Ang thought idly about the value of the gift. Yong Hongzhong paused for a while, as if he just remembered it. He turned around and said respectfully to the girl in gorgeous clothes on the other side of the crowd: "I also thank Dr. Qiu and An Le."
Princess."
"Princess Princess, just call me cousin."
The girl in gorgeous clothes, known as Princess Anle, smiled at Yong Hongzhong in a gentle and friendly manner, and her eyes accurately captured the eyes of everyone present.
And, Li Ang’s strange gaze.
