Chapter 729 Safety First
Fat people can withstand cold better than thin people.
This is because the fat layer of fat people is like a thick quilt, which effectively prevents the loss of heat in the body.
Zou Xuan, who is so thin that her bones are visible, is not very afraid of the cold, which means that she has heat in her body.
Suddenly realizing this, Yu Zhiming also realized his negligence.
When he was giving Zou Xuan a full body examination, he could clearly feel Zou Xuan's body surface temperature through physical contact.
Human body surface temperature is greatly affected by the external environment, ranging from 27 degrees to 37 degrees.
Yu Zhiming can still recall the feeling of giving Zou Xuan a physical examination twice. Although it felt a little rough to the touch, it was warm, and the body surface temperature should be above 36 degrees.
This is the normal value of body surface temperature, so Yu Zhiming naturally ignored it.
Now, Yu Zhiming asked the nurse to measure Zou Xuan's rectal temperature, which falls under the category of core body temperature.
Core temperature is a concept corresponding to body surface temperature. It is the body temperature mentioned in physiology or clinical medicine, and refers to the average temperature of the core area of the human body.
It is usually stable, generally at 37.5-38°C.
Under different ambient temperatures, the range of the human body's core area will change.
In a cold environment, the core area is concentrated in the head, chest and abdomen; in a hot environment, the core area can extend to the limbs.
Core body temperature is not easy to measure. In clinical practice, rectal temperature (i.e., anal temperature), oral temperature, and axillary temperature are usually measured to represent core body temperature.
Among them, rectal temperature is closest to core body temperature...
"Doctor Yu, I've taken my temperature. It's 37.6 degrees. Is this normal?"
"Do you have a fever?"
Yu Zhiming chuckled and said, "As long as the rectal temperature doesn't exceed 37.7 degrees, it's within the normal range."
"But this temperature is a bit too high for Zou Xuan, who is so skinny and frighteningly thin."
Finally finding something unusual, Yu Zhiming said cheerfully, "She doesn't have much body fat to keep warm, so maintaining this core temperature requires a lot of energy."
As a warm-blooded animal, humans need to maintain a stable body temperature, which is very energy-consuming.
More than 50% of the energy the human body obtains through nutrition is directly converted into heat energy to maintain body temperature.
The rest is transferred to the body to be converted into adenosine diphosphate and stored in the form of chemical energy to supply muscle contraction, nerve conduction, glandular secretion, etc.
In order to obtain enough energy and maintain body temperature, you need to eat food continuously.
In contrast, cold-blooded animals do not need to maintain a high body temperature and can survive for a long time after a good meal.
Take snakes for example. It usually takes a pet snake about ten days to slowly digest the food it eats.
Zou Xuan's situation is even worse.
Her body lacked fat to keep warm, just like a broken house with leaks on all sides. In order to maintain the temperature of the house, she could only continuously increase the fuel input.
This is probably why she eats quite a lot but is still so thin.
Most of the energy absorbed by the body is converted into heat to maintain body temperature.
Zhou Mo noticed the change in Yu Zhiming's tone and asked, "Doctor Yu, have you discovered the reason why Zou Xuan is so thin?"
Yu Zhiming pondered and said, "In a case like Zou Xuan's, the core body temperature should be 37.5 degrees Celsius, or even lower to be considered normal."
"But judging by her rectal temperature of 37.6, her core body temperature should be 38 degrees Celsius, or even slightly higher."
"This core body temperature is normal for a normal person, but it is abnormal for Zou Xuan."
Yu Zhiming said thoughtfully, "I suspect there's something wrong with Zou Xuan's body temperature regulation mechanism."
"so……"
Yu Zhiming instructed: "Zhou Mo, ask the nurse on duty to tell Zou Xuan and her mother to be prepared..."
"Let's go to Ning'an Hospital early tomorrow morning to get an enhanced MRI scan of the hypothalamus."
The function of regulating human body temperature is carried out by the hypothalamus deep in the brain, which is divided into the anterior hypothalamus and the posterior hypothalamus.
The function of the anterior hypothalamus is to regulate the body's heat dissipation.
If the ambient temperature rises or you are about to engage in strenuous exercise, the hypothalamus will send a signal to trigger the body's sweating function.
The posterior part of the hypothalamus regulates the rapid warming of the body to resist the cold.
If the body is in a cold environment, the posterior hypothalamus will receive temperature signals from cold receptors, instructing the subcutaneous blood vessels to reduce blood flow to the surface of the skin, lowering the skin temperature to slow down the loss of body heat.
The most important point is that the hypothalamus is the hub for regulating the secretion of thyroid hormones.
Thyroid hormones can promote the oxidative decomposition of substances and promote the generation of heat in the human body.
This is also why people with hyperthyroidism become thin and most of their energy is converted into calories and consumed.
However, when Yu Zhiming examined Zou Xuan, he was able to confirm that there was no problem with her thyroid gland.
Yu Zhiming guessed that there must be some minor problem with Zou Xuan's hypothalamus, which caused Zou Xuan's core temperature to remain at 38 degrees, which was higher than her body's needs, and consumed a lot of body energy in vain.
And this temperature level is also within the normal range of the human body, so the doctors who previously examined Zou Xuan habitually neglected it?
This should also be considered a kind of darkness under the lamp, right?
Because the hypothalamus is located deep in the human brain, it is a part that Yu Zhiming cannot reach and explore clearly.
Since Zou Xuan had previously undergone a brain scan with no findings, Yu Zhiming simply sent her to Ning'an Hospital for a highly accurate enhanced MRI scan...
It is said that men who work hard are the most attractive. Qing Ning felt hot in her heart when she saw Yu Zhiming with a glowing face.
"Zhiming, have you solved another difficult problem?"
Yu Zhiming chuckled and said, "It's hard to say yet. We need the MRI results tomorrow to verify it."
"But it's rare to find a suspicious point, so the possibility that it is the cause of the disease is still relatively high."
Qing Ning roared, "My Zhiming is the best!"
“Number one in the world.”
Yu Zhiming laughed and said, "You didn't drink much tonight, why do you look like you're drunk?"
"I am drunk even without drinking wine."
Qing Ning looked at Yu Zhiming with affection, and the moisture in her eyes was so clear that it could be drawn into threads.
Zhou Mo was a little embarrassed to watch, and snorted and jokingly said, "Do you want to find an underground parking lot to stop temporarily? I'll keep out of the way for half an hour so you two can do your thing?"
Qing Ning gave her a glare and said without much shyness, "Zhou Mo, when you have someone you love, you will understand what it feels like to be in love."
Yu Zhiming quickly said, "Okay, okay, let's not talk about this topic anymore. I'm still driving."
“Safety first! Safety first!”
Yu Zhiming took the initiative to change the subject and said, "The third underground floor of the old specimen building will be put into use this Friday."
"Zhou Mo, notify all of them to report on Friday and familiarize themselves with the work environment."
Zhou Mo hummed, then asked, "Will Dr. Qin from the Department of Traditional Chinese Medicine at Union Hospital also report in on Friday?"
Yu Zhiming thought for a moment and said, "Let him come next Monday."
After a pause, he asked again: "Zhou Mo, are you going to Qiao Lei's wedding this Saturday?"
Zhou Mo hummed and said, "After all, we are colleagues in the office, so we should always give each other some respect."
"Also take a look at the quality of their wedding banquets."
Yu Zhiming added, "When you present the gift, please compare yourself to Dr. Han and Dr. Xie and give me a red envelope."
Zhou Mo replied "Okay" and asked, "Doctor Yu, have you decided on the location for your wedding banquet?"
Qing Ning replied: "It hasn't been decided yet."
"My eldest brother's wedding banquet is scheduled for today at the Lijing Hotel. My dad said that my wedding and my eldest brother's wedding were a bit close together, and since we were in the same hotel, the banquets would inevitably have similar flavors."
"He is looking for other suitable locations."
"It's just that there are a lot of guests, and there aren't many restaurants that can accommodate us. Some of the good places have already been booked."
Qing Ning chuckled again, "My dad also said that there is a backup plan, which is to find a suitable open space and hold an open-air wedding and banquet."
Yu Zhiming smiled and said, "This plan is not bad."
"In our rural area, wedding and funeral banquets are basically held outdoors."
Zhou Mo commented, "Qing Ning, your wedding is in late October. It will be a clear and crisp autumn day, so an outdoor wedding would be perfect."
"The only thing I'm worried about is the weather and typhoons."
Qing Ning hummed and said, "That's what my dad is worried about, so the open-air wedding is just a backup plan."
Zhou Mo chuckled and said, "There are so many ways to have an open-air wedding, like helicopters, hot air balloons..."
Yu Zhiming interrupted, "No need for any new tricks, just follow the traditional wedding steps."
"New tricks mean new unexpected risks."
Zhou Mo curled his lips and asked, "Doctor Yu, I guess you have never done bungee jumping before?"
Yu Zhiming said with a look of disdain, "What's so fun about bungee jumping? If you're not careful, there are dangers like temporary blindness, joint damage, fainting, and shock. It's a typical waste of money."
Zhou Mo asked again: "Qing Ning, you must have played it before, right?"
Qing Ning said with a guilty conscience, "I've done this before when I was hanging out with my friends and was encouraged to do it."
She added, "I don't feel very good. It's just like what my husband Zhiming said. I'm just asking for trouble..."
Time passed quickly as the three of them chatted, and at 10:10 in the evening, they returned to Junshan Mansion.
After entering the elevator, Qing Ning pressed herself tightly against Yu Zhiming, twisting her little body back and forth.
“Husband…husband…”
Yu Zhiming hugged the girl to prevent her from moving around, and reminded her: "Why are you so impatient? There are surveillance cameras in the elevator."
"Hehe, don't be afraid, hugging each other is not too much..."
As soon as she entered the house, Qingning couldn't wait to jump on Yu Zhiming's body, and her pair of strong and elastic long legs were tightly wrapped around Yu Zhiming's waist.
Yu Zhiming was about to respond enthusiastically, but he noticed something was wrong in the living room and hurriedly said, "Come down, come down first."
Qing Ning roared, "Auntie should be asleep. She won't come out even if she hears any noise."
"Hubby, we're not afraid of anything..."
At this moment, a clear cough suddenly sounded.
Hearing this sound, Qingning slid off Yu Zhiming and hid behind him like a monkey.
The next moment, she stuck half of her head out and looked at the two people in the living room, blushing and saying, "Mom, aunt, why are you here?"
"Why didn't you call and tell me in advance?"
When Yu Zhiming saw his mother-in-law and Qingning's aunt suddenly appear in his home, he felt much more nervous than Qingning.
The incident with my father-in-law has been exposed?
