"Accidentally, this is the most wonderful thing in the world,

It is indescribable, difficult to guess, and difficult to understand.

Medical accidents, traffic accidents, sudden diseases, food poisoning, falling objects from high altitudes, falling from high altitudes, fires, drowning, electric shocks...

Human life is so fragile,

A glass of water, an icicle, a chopstick, a fork, and even a nut are enough to kill people.

In modern life, there are so many tools that people have to face every day. The ways of death that may be caused are even more bizarre and fancy than what is shown in the movie "The God of Death" or the TV show "1,000 Ways of Death".

The boy spread his hands and smiled, "Death is the destination of everyone and the fairest thing in the world."

If the murder case is shocking and angry, it will be recorded, and countless people will work together to investigate the truth behind it.

Then unexpected death is filled with sorrow and grief, helplessness, and sometimes a little bit of black humor.

Similarly, no one cares too much about the opposite of unexpected death, even media that pursues traffic will not - this is an accident, a helpless fate.

And I am responsible for causing accidents.”

Maybe this passage is suspected of boasting, and the smile on the boy's face is a little shy, "As time goes by, I am getting better at this,

Even if the entire accident process is fully displayed to the world, no one can find the complete context of the story before the end of the matter.

Just like a world-class magician or a ruthless criminal conspirator in reasoning.”

—————

"Sister Lan, do you suspect someone is chasing these criminals?"

"Um."

Wei Linglan nodded, looked at Chu Yin who was flipping through the information, and nodded, "These cases are all ordinary, but I always feel that there is something wrong with it.

I am not an expert in this area, and the criminal investigation course scores in the bureau are not very high.

You are smarter, see if there is any problem here.”

Chu Yin "hmm" the doctor, sucked the coke that was left with little ice, and stared at the information intently.

"Huang Yuanwei, male, 46 years old, driver, was a contact person in a criminal gang before.

One morning last summer, while driving to Lincheng, he suddenly felt that his breathing was getting more and more difficult, his throat and chest tightened.

The pain like needles kept coming from the fingertips, and the palms could hardly hold the steering wheel, and the road scene in front of me began to appear.

For safety reasons, he rushed to the hospital for treatment after barely driving off the highway.

When he arrived at the emergency department, his condition was already very bad, his complexion was pathologically red, he was gasping for a while, and his chest was fluctuating significantly, but the results of both physical and neurological examinations were relatively normal.

Considering that he was on a business trip outside the country yesterday, he ate local food, and combined with his previous history of allergic diseases,

The doctor thought this was a common allergic symptom, so he took the anti-allergic drug diphenhydramine - this drug has the effect of antihistamine h1 receptor, can inhibit the central nervous system, and is suitable for allergic diseases of the skin and mucous membranes, such as urticaria, dead grass fever, allergic rhinitis, etc.

Histamine is an active amine compound that is present in mast cells and in mucosal tissues such as lungs, liver, and stomach.

Histamine is released when the body discovers allergens.

Histamine, which is a chemically conductive substance, binds to the receptor on the vascular smooth muscle, causing vasodilation and thus local edema.

It also causes the tracheal smooth muscle of the lung to contract, causing respiratory tract stenosis and difficulty breathing.

Blood pressure decreases and heartbeats accelerate.

The doctor used diphenhydramine to block histamine and gave Huang Yuanwei an adrenaline to contract his dilated blood vessels.

If he has allergic symptoms, this should work.

However, after several hours of observation, Huang Yuanwei's condition did not improve. He still felt uncomfortable and claimed that his stomach began to burn, and even if he took oral antacid drugs, it would be useless.

Then, he felt his throat tight and swollen, unable to speak or swallow, his heartbeat quickly and his eyelids drooped.

The doctor immediately performed various examinations on him, including MRI magnetic resonance imaging, but the examination results showed no problems.

Huang Yuanwei's situation continued to deteriorate at a strange speed.

His face and throat muscles were paralyzed, unable to speak, unable to move his hands and feet, and his eyelids were drooping and unable to open them. He could only use a respirator to help him breathe.

The most terrifying thing is that his will is still clear.

He could clearly feel that he was losing control of all his muscles little by little.

He could clearly feel that his body was constantly paralyzing.

He lost his life before the doctor gave further treatment.

It was not until after his death that the doctors understood the cause of his death.

His acute muscle paralysis is not a problem with the brain or spine, because his paralysis throughout his body is very balanced, average, and synchronized.

It cannot be a nerve virus infection - viruses such as polio that can cause paralysis throughout the body will cause the patient to fall into a fever for several days before causing muscle paralysis.

Therefore, it can only be a problem with the neuromuscular junction.

Motor neurons located in the anterior horn of the spinal cord and some nerve nuclei of the brain stem emit nerve fibers to the muscles. The nerve fibers are divided into dozens or hundreds of branches at the muscle fibers.

Each branch terminates on the muscle fibers to form a one-to-one neuromuscular junction.

The neuromuscular junction can convey the signal of nerve fibers to the muscle fibers, causing the muscle to contract. If the neuromuscular junction is interrupted, it will cause muscle atrophy and paralysis."

Chu Yin frowned and said, "What causes the neuromuscular junction failure is..."

"Botoxin."

The young man smiled and said to the old woman, "Look, the whole process of muscle movement,

It is a command transmitted from the nerve center.

Let nerve impulses be transmitted to the axonal ends,

It stimulates the protruding small cells in the presynaptic membrane, releases neurotransmitters such as acetylcholine, diffuses to the synaptic cleft, binds to receptors on the sarcoid, and causes muscle contraction.

Botox toxin binds to the presynaptic membrane of cholinergic neurons to endocytize cells to form an acidic vesicle that encapsulates toxin molecules, which remains at the end of the presynaptic membrane of motor neurons.

Prevent the release of the normal neurotransmitter acetylcholine,

This causes muscle paralysis.

I kept observing it secretly, and it turned out that the official was as I expected.

Following the botulinum toxin that Huang Yuanwei ate, he found the food he ate in the restaurant yesterday - a portion of ham originally packed in canned food.

The owner of that restaurant happened to be a murder suspect who had been absconding for many years.

Botox toxin is required to produce canned foods, and the temperature and pH value of the external environment must be completely appropriate.
