"The accident is that this is the most amazing thing in the world,It is indescribable, unpredictable, unpredictable.Medical accidents, traffic accidents, sudden illnesses, food poisoning,
falling objects, falling from heights, fires, drowning, electric shocks...Human life is so fragile,A glass of water, an icicle, a chopstick, a fork, or even a nut are enough to
kill a person.In modern life, there are so many tools that people face every day. The
possible methods of death are even more weird and fancy than those shown in
the movie "Reaper is Coming" or the TV show "1000 Ways to Die". "The young man smiled and said, "Death is everyone's destination, and it is
also the fairest thing in the world.If the murder case is shocking and anger, it will be recorded, and countless
people will cooperate to investigate the case and investigate the truth behind
it.Then the accidental death is tinged with sadness, helplessness, and sometimes
a little black humor.Similarly, for the opposite of accidental death, no one cares much about
persistence, even if it is the media that pursues traffic-this is an accident
and a fate of helplessness.And I am responsible for making accidents. "Maybe it’s the suspicion of boasting in this passage, and the smile on the
boy’s face is a bit shy, "As time goes by, I am getting better and better at
this.Even if the entire accident process is shown to the world in its entirety, no
one can find the complete context of the story before the event is over.Just like a world-class magician, or a ruthless criminal conspiracy scholar in
reasoning. "——————"Sister Lan, do you suspect that someone is hunting down these criminals?""Ok."Wei Linglan nodded, looking at Chu Yin who was reading the information,
nodded, "These cases are common, but I always feel that something is not
normal.I am not an expert in this area, and the scores of criminal investigation
courses in the bureau are not very high.You are smarter and see if there are any problems. "Chu Yin "hmm" to the doctor, inhaled the little Coke left on the ice, and
stared at the information intently."Huang Yuanwei, male, 46 years old, driver, used to be a contact person in a
criminal gang before that.One morning in the summer of the previous year, when he was driving to the
city, he suddenly felt that his breathing was getting more and more difficult,
his throat and chest were tight.Acupuncture-like pain kept coming from my fingertips, my palms could hardly
hold the steering wheel, and the road scene in front of me began to appear
doubled.For safety's sake, after reluctantly driving off the highway, he immediately
went to the hospital for treatment.When he arrived in the emergency department, his condition was already very
bad. His complexion was sickly red, he was panting, his chest was undulating
greatly, but the physical and neurological examination results were relatively
normal.Considering that he ate local food on a business trip yesterday, combined with
his previous history of allergies,The doctor thought it was a common allergic symptom, so he gave him the anti-
allergic drug diphenhydramine, which has antihistamine H1 receptor effect, can
inhibit the central nervous system, and is suitable for allergic diseases of
the skin and mucous membranes, such as urticaria. , Hay fever, allergic
rhinitis, etc.Histamine is an active amine compound that exists in mast cells and also in
mucosal tissues such as lung, liver, and stomach.When the body finds an allergen, it releases histamine,Histamine, which is a chemical conductive substance, binds to the receptor on
the vascular smooth muscle, causing vasodilation and local edema.And it causes the tracheal smooth muscles of the lungs to contract, causing
narrowing of the airways and difficulty breathing.Blood pressure decreases and heartbeat increases.The doctor blocked histamine with diphenhydramine and gave Huang Yuanwei
adrenaline to shrink his dilated blood vessels.If he is allergic, then 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 was starting
to burn, even if he took oral antacids to no avail.Then, he felt tight and swollen in his throat, unable to speak or swallow, his
heartbeat rose rapidly, and his eyelids drooped.The doctor immediately performed various examinations including mri magnetic
resonance imaging, but the examination results showed no problems.Huang Yuanwei’s situation continued to deteriorate at a weird rate.His facial and throat muscles were paralyzed, unable to speak, unable to move
his hands and feet, and his eyelids were drooping and unable to open. He could
only breathe with a respirator.The scariest thing is that his will is still sober,He can clearly feel that he is losing control of all his muscles bit by bit,He can clearly feel that his body is constantly being paralyzed.He lost his life before the doctors gave further treatment.It was not until after his death that the doctors understood the cause of his
death.The acute paralysis of his muscles is not a problem of the brain or spine,
because the paralysis of his whole body is very balanced, average and
synchronized.Nor can it be a viral infection of the nerves-viruses such as polio, which can
paralyze the whole body, can cause the patient to fall into fever for several
days before causing muscle paralysis.Therefore, only the neuromuscular junction is faulty.The motor neurons located in the anterior horn of the spinal cord and some
nerve nuclei of the brainstem send out a single nerve fiber to the muscle. The
nerve fiber is located at the muscle fiber, each branching into tens or
hundreds of branches.Each branch terminates on a muscle fiber, forming a one-to-one neuromuscular
junction,Neuromuscular junctions can transmit signals from nerve fibers to muscle
fibers, causing muscles to contract. If the neuromuscular junction is
interrupted, it will cause muscle atrophy and paralysis. "Chu Yin frowned and said, "And the cause of neuromuscular junction failure
is...""Botulinum toxin."The boy smiled and said to the old woman: "Look, the whole process of muscle
movement,It’s a command from the nerve center,To transmit nerve impulses to the axon ends,The protruding cells in the presynaptic membrane are stimulated to release
neurotransmitters such as acetylcholine, which diffuse to the synaptic cleft
~www.mtlnovel.com~ and bind to the receptors on the muscle membrane to trigger
muscle contraction.The botulinum toxin binds to the presynaptic membrane of cholinergic neurons
and undergoes endocytosis to form an acidic vesicle that envelops the toxin
molecule and stays at the end of the presynaptic membrane of motor neurons.Prevent the release of the normal neurotransmitter acetylcholine,Thus paralyzing the muscles.I have been observing secretly, and it turned out that afterwards the official
was as I expected,Following the botulinum toxin ingested by Huang Yuanwei, he found the food he
ate in the restaurant yesterday—a piece of ham that was originally in a can.And the owner of that restaurant happened to be a murder suspect who had
absconded for many years.To produce botulinum toxin in canned food, the temperature and pH of the
external environment must be completely appropriate.This is a perfect and regrettable accident. "Please remember the domain name of the book’s first publication:. 4Fiction
