Gu Yanan and Gu Jiashu realized at the same time that the cause of this encephalitis epidemic of unknown cause may not be a virus, but poisoning, and the source of the disease is likely to be medicine.

The members of the emergency response team began to work separately to go to the homes of each child and bring the Chinese patent medicine taken by the child from the TCM hall back to the CDC laboratory for testing.

Colleagues in the physicochemical group of the laboratory analyzed the drug components, and the results came out quickly.

Gu Yanan got the test results and gasped, it turned out that the so-called miracle medicine in the mouths of the patient's family was a mixture of banlangen granules, antibiotics, hormones and anthelmintic drugs.

The most of the miracle drugs are the root of the banlange, in addition to the antibiotic drug - penicillin, and the hormone drug - dexamethasone, and a deworming drug that has long been discontinued - tetraimidazole.

In the 80s of the last century, tetraimidazole was used on a large scale in the population as an intestinal anthelmintic drug.

After a period of time, tetraimidazole was found to have serious toxic side effects, one of which is that it can cause encephalitis-like syndrome.

In the literature of the 80s, there were many reports of such cases, in which the symptoms of the patient were the same as those of encephalitis of unknown cause, nausea and vomiting, weakness of the limbs, confusion, drowsiness or confusion, twitching of the limbs, and resistance of the neck......

There have been reports of suicide attempts by taking a large amount of the anthelmintic drug tetraimidazole, and it has been successful.

Tetraimidazole was therefore discontinued.

There have been no reported cases of encephalitis in the decades since tetramidazole was discontinued, so Gu Jiashu did not expect that this unexplained encephalitis was due to the toxic side effects of the drug.

All the children had used the "miracle medicine" prescribed by the Hua's Medical Center in the urban village.

This so-called miracle drug actually uses tetraimidazole, which has been banned, and the content is very high.

The miracle drug containing tetraimidazole is the source of this outbreak of encephalitis of unknown cause.

I don't know how many of these miracle drugs there are, and which children have taken them, so if you want to investigate clearly, you have to find the person who sells the miracle medicine.

——

Urban Village in the southern suburbs of Lianhai City, Hua's Medical Center.

Gu Yanan, Lu Li, and Xiao Chu drove the on-site flow shunting car and parked in the alley downstairs of the Hua Medical Center.

Standing downstairs and looking up, you can see the humble little sign of the Fahrenheit Medical Center.

The CDC group went up the narrow and gloomy staircase to the second floor.

The small door to the Fahrenheit Medical Center was closed.

Gu Yanan knocked on the door, but no one responded for a long time, and just when she thought there was no one in the hospital, the small door was opened from the inside.

An old man with gray hair appeared.

"Are you Dr. Hua Guoqiang?" Gu Yanan asked.

The old man looked behind Gu Yanan vigilantly, and found that there were no children behind her, but two young men following.

"What do you guys do?" The old man asked in a low voice.

Gu Yanan showed his work card, "We are the staff of the Municipal Center for Disease Control and Prevention, and we suspect that you are related to an epidemic of encephalitis of unknown cause, and now we want to conduct sampling and investigation of your medical center." ”

The old man hesitated for a moment, "Wait a minute. ”

Then the door slammed shut, and there was the sound of locking from the inside.

Gu Yanan thought to himself, this old god stick won't want to destroy the evidence, right?

Gu Yanan was about to knock on the door again, when he suddenly heard the sound of a heavy object falling downstairs, followed by the alarm sound of the battery car being hit hard.

Lu Li looked out through the window of the staircase corridor and found an old man jumping from the second floor, and that old man was Hua Guoqiang who opened the door just now.

"Sister Yanan, that old man jumped off the building just now and ran away."

Gu Yanan immediately leaned over the window of the corridor and looked down, and found that the old man had already gotten up from the ground, carrying a bag on his back, and fled in a hurry.

This is afraid of being responsible, and began to run away.

Disease control is only responsible for sampling and flow investigation, but is not responsible for arresting people, and has no ability to arrest people.

Gu Yanan was very anxious, thinking that if he was escaped by this old god stick, then the magic medicine sold would not be traced, and he didn't know how many people would be victimized.

It would be nice if Nan Hanfei was here, Gu Yanan had a thought in his heart.

Just thinking about it, several black shadows suddenly flashed downstairs, pressing Hua Guoqiang, who was escaping, to the ground.

Nan Hanfei walked out of the crowd, leaned over and patted Hua Guoqiang's head with his hand, "Doctor Hua, do you know that we are going to find you?" Can't wait to jump off the building to greet us? ”

The old man Hua Guoqiang struggled on the ground, "Who are you?" Why arrest me? ”

"What did you do before, don't you know? Don't know who we are? ”

Hua Guoqiang thought of the people from disease control who came to knock on the door just now, "What right do you disease control people have to arrest me?" ”

After Nan Hanfei heard this, he actually laughed, "Yo, the people from disease control also want to arrest you?" You've committed a lot of crimes, so come back to the police station with me and explain slowly. ”

As soon as Hua Guoqiang heard that it was a policeman, his face immediately turned like ashes, and his body, which was struggling violently, also quieted down.

"Xiao Li, take people to the police car."

Nan Hanfei instructed Xiao Li to look up and see Gu Yanan's exposed head in the upstairs window.

"Hey!" Nan Hanfei smiled and waved his hand to greet Gu Yanan upstairs.

"Wait a minute, I have something to ask you."

Gu Yanan trotted downstairs and came to Nan Hanfei.

"Why did you police arrest him?" Gu Yanan asked.

"Why are you CDC looking for him?" Nan Hanfei did not answer, but asked rhetorically.

"Hua Guoqiang sold counterfeit drugs, which caused drug-reactive encephalitis in many children, and our CDC came to his clinic to investigate and take samples, and to trace the whereabouts of these drugs. You police shouldn't have arrested him because of this, right? ”

"Well, I really don't know about what you just said, our police arrested him because he carried two murders.

This person has been on the run since he got into a fight with someone 4 years ago and killed two people, and is wanted by the whole country. Some time ago, our police received news that he had recently appeared in Lianhai City, and changed his name and surname, and opened a small medical center. ”

Gu Yanan didn't expect that this old god stick still had two lives on his body.

"We at CDC want to know as soon as possible how he made counterfeit drugs and to whom he sold them? This is important to control this outbreak of drug-responsive encephalitis. ”

Nan Hanfei originally wanted to take Hua Guoqiang back to the police station for interrogation, sort out the information and then tell Gu Yanan the news, but now seeing that Gu Yanan is so anxious, and the information that Hua Guoqiang has affects many lives, so he decided, "Okay, you go to the police car with me now for questioning." ”

Hua Guoqiang was escorted into a police car and handcuffed.

"Li Youcai." Nan Hanfei shouted at him.

The old man looked up, then lowered his head and remained silent.

"Li Youcai, this is your name 4 years ago, you won't remember it, right? 4 years ago, you were a mason, but now you have become a miracle doctor, and you are really fast at studying medicine. ”

The old man, who was handcuffed, remained silent.

Nan Hanfei gave Gu Yanan a look and motioned for her to ask.

"Hua Guoqiang, where did the magic medicine in your hospital come from? Who are they sold to? ”

The old man was still silent, deaf to Gu Yanan's questioning, with an attitude that I won't say anything, and you can't do anything to me.

Nan Hanfei was about to raise his hand to fight, but was stopped by Gu Yanan.
