Fat people are more resistant to frost than thin people.

It is because the fat layer of the fat person is like a thick quilt, which effectively prevents the loss of heat in the body.

Zou Xuan, who is skinny and skinny, is not afraid of cold, which means that she has heat in her body.

Suddenly aware of this, Yu Zhiming also realized his negligence.

When he gave Zou Xuan a full body examination, he could clearly feel Zou Xuan's body surface temperature through body contact.

The human body surface temperature is greatly affected by the external environment, from 27 degrees to 37 degrees.

Yu Zhiming can still recall the feeling of giving Zou Xuan a physical examination twice, although he touched his hands a little awkwardly, it was warm, and the body surface temperature should be above thirty-six degrees.

This is a normal value of body surface temperature, and Yu Zhiming naturally ignored it.

Now, Yu Zhiming asked the nurse to measure Zou Xuan's anal temperature, which belongs to the category of core temperature.

Core temperature is a concept corresponding to body surface temperature, which is the body temperature referred to in physiology or clinical medicine, which refers to the average temperature of the core area of the human body.

It is usually stable, generally 37.5-38C.

At different ambient temperatures, the extent of the core area of the human body changes.

In cold environments, the core area is concentrated in the head, chest and abdomen; In hot environments, the core area can extend to the extremities.

The core temperature is not easy to measure, and the rectal temperature, oral temperature, and axillary temperature are usually measured clinically to represent the core temperature.

Among them, the anal temperature is closest to the core temperature......

"Dr. Yu, the temperature has been measured, and it is 37.6 degrees. Is this temperature value normal? ”

"Do you have a fever?"

Yu Zhiming chuckled: "As long as the anal temperature does not exceed 37.7 degrees, it is normal." ”

"But this temperature is a bit too high for Zou Xuan, who is skinny and scary."

Finally made an abnormal discovery, Yu Zhiming said happily: "She doesn't have much fat to keep her warm, and if she wants to maintain such a core temperature, she consumes a lot of energy." ”

As homeothermic animals, humans need to maintain a stable body temperature, and maintaining body temperature is very energy-intensive.

More than 50% of the energy obtained by the human body through nutrition is directly converted into heat energy to maintain body temperature.

The rest is transferred to the body to convert adenosine diphosphate into adenosine triphosphate, which is stored in the form of chemical energy to supply muscle contraction, nerve conduction, gland secretion, etc.

In order to get enough energy and maintain body temperature, you need to eat food constantly.

On the contrary, ectotherms do not need to maintain a high body temperature, and they can survive for a long time after a full meal.

Take snakes as an example, pet snakes eat food once, and it generally takes about ten days to digest it slowly.

And Zou Xuan's situation is even worse.

Her body lacks fat insulation, like a dilapidated house leaking on all sides, and in order to maintain the temperature of this house, she can only continue to increase fuel input.

This should be the reason why she eats not too little, but she is still so lean.

Most of the energy absorbed by the body is converted into heat to maintain body temperature.

Zhou Mo heard the change in Yu Zhiming's tone and asked, "Doctor Yu, is this the reason why you found Zou Xuan thin?" ”

Yu Zhiming groaned and said: "In Zou Xuan's case, the core temperature should be 37.5 degrees, or even lower. ”

"But judging from her anal temperature of 37.6, her core temperature should be at 38 degrees, or even slightly higher."

"This core temperature is normal for normal people, but for Zou Xuan, it is abnormal."

Yu Zhiming said thoughtfully: "I suspect that there is something wrong with Zou Xuan's thermoregulation mechanism. ”

"...... like this"

Yu Zhiming advised: "Zhou Mo, you ask the nurse on duty to tell Zou Xuan and her mother so that they can prepare......"

"Rush to Ning'an Hospital early tomorrow morning to do an enhanced MRI examination of the hypothalamus."

The hypothalamus, which regulates the body's body temperature, is responsible for the anterior and posterior hypothalamus, respectively.

The role of the anterior part of the hypothalamus is to regulate the body's heat dissipation.

Suppose the ambient temperature rises, or when you are going to do strenuous exercise, the hypothalamus sends signals to trigger the body's sweating function.

The back of the hypothalamus has the effect of regulating the rapid temperature of the human body to resist the cold.

When the body is in a cold environment, the back of the hypothalamus receives a temperature signal from the cryoreceptors, directing the blood vessels under the skin to reduce blood flow to the surface of the skin, and lowering the skin temperature to slow down the loss of body heat.

Most importantly, the hypothalamus is the pivotal site that regulates thyroid hormone secretion.

Thyroid hormones can promote the oxidative decomposition of substances and promote the production of heat in the body.

This is also why with hyperthyroidism, the human body will become emaciated, and most of the energy is converted into calories and consumed.

However, when Yu Zhiming examined Zou Xuan, he could confirm that there was no problem with her thyroid gland.

Yu Zhiming guessed that it should be Zou Xuan's hypothalamus that had some minor problems, which kept Zou Xuan's core temperature at a level of 38 degrees that exceeded 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 this made the doctors who examined Zou Xuan before inertial negligence?

This should be a kind of darkness under the lamp, right?

Because the hypothalamus is located in the depths of the human brain, it is beyond the reach of Yu Zhiming's power and cannot be explored.

In view of the fact that Zou Xuan had also done a brain examination before, and found nothing, Yu Zhiming simply asked her to go to Ning'an Hospital to undergo an enhanced MRI examination with the highest accuracy of an exploration......

It is said that men who work hard are the most attractive, and Lime looked at Yu Zhiming, whose face was full of light, and his heart was also hot.

"Zhiming, another incurable disease has been solved?"

Yu Zhiming said with a smile: "It's hard to say, I need to verify the results of the MRI examination tomorrow." ”

"However, it is rare to find a suspicion, the possibility of the cause is still relatively large."

Lime roared, "My house is the best!" ”

"No. 1 in the world."

Yu Zhiming laughed and said, "You haven't drunk much tonight, how do you feel like you're drunk." ”

"I'm not drunk, and everyone is drunk."

Lime looked at Yu Zhiming with affection, and the wetness in his eyes could be drawn.

Zhou Mo was a little dumbfounded, and said with a smile: "Do you want to find an underground parking lot to stop temporarily, I will avoid it for half an hour so that the two of you can do something?" ”

Lime glanced at her, and said without much shyness: "Zhou Mo, when you also have a beloved, you will understand what it feels like to be in love." ”

Yu Zhiming hurriedly spoke: "Okay, okay, don't talk about this topic, I'm still driving." ”

"Safety first! Safety first! ”

Yu Zhiming took the initiative to change the topic and said: "The old specimen building has three underground floors, and it will be put into use this Friday." ”

"Zhou Mo, inform all of them, report on Friday, and familiarize yourself with the working environment."

Zhou Mo snorted and asked again: "Doctor Qin from the Chinese Medicine Department of Union Hospital, is he also here to report on Friday?" ”

Yu Zhiming thought for a while and said, "Let him be next Monday." ”

After a pause, he asked again: "Zhou Mo, are you going to attend Qiao Lei's wedding this Saturday?" ”

Zhou Mo snorted and said, "After all, he is a colleague in the office, and he always has to give face." ”

"Look at the level of their wedding receptions as well."

Yu Zhiming said again: "When you salute, you compare the level of Doctor Han and Doctor Xie and give me a red envelope." ”

Zhou Mo responded with a "yes" and asked, "Doctor Yu, has the location of your wedding banquet been decided?" ”

Lime replied, "It's not decided yet." ”

"My eldest brother's wedding banquet is scheduled for today's Lijing Hotel. My dad said that my eldest brother and I had a close wedding time, and the same hotel, the taste of the banquet was inevitably the same. ”

"He's looking for other suitable locations."

"It's just that there are a lot of guests, and there are not many restaurants that can host it, and some good places have been booked."

Lime grinned again: "My dad also said that there is a plan to find a suitable open space to hold an open-air wedding and an open-air banquet. ”

Yu Zhiming smiled: "This plan is not bad. ”

"In our rural areas, the banquets are basically open-air."

Zhou Mo expressed his opinion: "Lime, your wedding is in late October, when the autumn is crisp, and it is perfect to hold an open-air wedding." ”

"The only worries are the weather and typhoons."

Lime snorted and said, "This is also what my dad is worried about, so the open-air wedding is just a support plan." ”

Zhou Mo said: "Open-air weddings can be done in a variety of ways, helicopters, hot air balloons, ......"

Yu Zhiming interrupted: "You don't need new tricks, just follow the traditional marriage steps." ”

"New tricks mean new unexpected risks."

Zhou Mo pursed her lips and asked, "Doctor Yu, I guess you must not have played bungee jumping, right?" ”

Yu Zhiming said with a disgusted face: "What's so fun about bungee jumping?" If you are not careful, you can also have the risk of temporary blindness, joint damage, syncope shock and so on. Typical spending money to buy sin. ”

Zhou Mo asked again: "Lime, you must have played, right?" ”

Lime said with some weakness: "When I used to go out with my friends, I was encouraged to play. ”

She added: "It doesn't feel very good, it's really as my family Zhiming said, it's spending money to buy sin and ......."

Time flowed quickly in the small talk of the three of them, and at ten o'clock in the evening, they returned to Junshan Mansion.

After entering the elevator, the lime was tightly attached to Yu Zhiming's body, and his small body kept twisting around.

"Husband... Husband ......"

Yu Zhiming hugged this guy, didn't let her move, and reminded: "What is the monkey anxious about?" The elevator is monitored. ”

"Hee-hee, don't be afraid, hug each other and don't ...... too much"

As soon as he entered the house, Lime couldn't wait to jump on Yu Zhiming's body, and a pair of powerful and elastic long legs were firmly wrapped around Yu Zhiming's waist.

Yu Zhiming just wanted to respond enthusiastically, but he noticed that the situation in the living room was different, and hurriedly said: "Come down, come down first." ”

Lime roared, "Auntie should be asleep, even if she hears the movement, she won't come out." ”

"Husband, we're not afraid to ...... no matter what we do"

At this moment, a clear cough suddenly sounded.

Hearing this sound, the lime slid down from Yu Zhiming's body, and the monkey generally hid behind Yu Zhiming.

The next moment, she poked out half of her head, looked at the two people in the living room, and said with a red face: "Mom, aunt, why are you here?" ”

"Why don't you call and say it in advance?"

Yu Zhiming saw his mother-in-law and Aunt Lime who suddenly appeared in his house, and his heart was much more nervous than Lime.
