Chapter 2773: 2574 Medicine is Three-Part Poison

Zheng Ren sat in the car, behind him countless luxury cars had already been 'persuaded' to retreat.

Yan Zhangsen stayed behind to deal with his assistant and those people, while he himself accompanied Zheng Lao Ban back to the old residence.

The car drove through Yangcheng's urban area, a bit congested, but Zheng Ren had long been accustomed to such traffic jams in a big city.

For example, running from home to 912 is a bit faster than driving. The electric car he had wanted to buy is completely unnecessary.

He asked Yan Zhangsen once how that patient was doing, and Yan Zhangsen just smiled without saying anything.

Zheng Ren worried about having to change dressings and remove stitches after surgery, but the patient wasn't there, so telling the patient's family was enough; he felt that once he'd explained it, it was done, and further talk had nothing to do with him.

Su Yun felt bored; the most gossipy thing Yan Zhangsen wouldn't say made it especially boring. He picked up his phone, suddenly frowned and said: "Boss, that Master Xiao is hospitalized."

"Huh, hasn't he been hospitalized all along?" Zheng Ren didn't think much of it.

"No, no, you've misunderstood." Su Yun said doubtfully: "They said it was cerebral hypoxia, renal failure; if resuscitation succeeded, there's a high chance he'd become a vegetative state."

"……" Zheng Ren stared for a moment, wondering what the reasoning was.

He tried to recall Xiao Kai, Master Xiao's system panel earlier; coronary artery atherosclerotic heart disease wasn't serious, just go to the hospital for a few days of medicine or take oral meds for a while and it would be fine—how could there be cerebral hypoxia and renal failure?

Could there be some problem he hadn't noticed? Zheng Ren carefully reconsidered the system panel from back then—there was nothing wrong…… really strange.

But Zheng Ren didn't ask; he watched Su Yun fiddling with his phone, both hands a blur as he typed nonstop—this speed was faster than speaking, a shame he didn't become an esports pro.

But at this age, even if he were a professional player at his age, it wouldn't be much different from a 40-year-old Mutombo.

After a few minutes, Su Yun looked at Zheng Ren with a helpless, laughing-crying expression and said: "Boss, that guy woke up that night in the Emergency Department of the Medical University Affiliated Hospital and then discharged himself without signing anything."

"And then?" Zheng Ren asked, frowning.

"Just now the 120 emergency service sent him to the hospital; they're still investigating, initially considering that an overdose of oral nitroglycerin caused peripheral venous dilation, reduced venous return, and with delayed treatment led to cerebral and renal ischemia."

"……"

Zheng Ren really didn't know what to say.

"Overdose on nitroglycerin? Who?" Yan Zhangsen asked.

Su Yun told him about Master Xiao, but he hadn't expected Yan Zhangsen to know this person.

"That swindler, I know him." Yan Zhangsen said: "The one they said going to the hospital was a near-death experience. A few years ago in the UK, a diabetic patient listened to him, stopped subcutaneous insulin injections, and started treating illness by slapping the meridians; soon he developed ketoacidosis and couldn't be rescued."

After saying that, Yan Zhangsen curiously asked: "What's going on this time? Did he go to the capital?"

"For someone who normally doesn't take medicine, once they start taking drugs they treat it like food, just to fill their stomach." Su Yun said disparagingly.

"I think the problem is the way oral nitroglycerin is taken." Zheng Ren pondered a few seconds then said: "The correct way to take nitroglycerin tablets is sublingual; the sublingual area has many capillaries, allowing faster entry into the bloodstream to exert the drug's effect."

"About one minute, though some say it takes effect in 2-3 minutes and reaches peak blood concentration in five." Su Yun said: "I guess he first swallowed a certain dose of nitroglycerin with water, found it ineffective, felt severe precordial pain, panicked, and then remembered he should take it sublingually."

"Yeah, that's probably it. When panicking… at the onset of illness there's a near-death sense of fear; likely he was afraid of death and directly held a super-dose of nitroglycerin under his tongue. Or he held too large a dose at once, and as time passed, after hepatic metabolism another portion of the drug slowly entered the bloodstream."

"No, hepatic first-pass effect means the drug's utilization is only about 8%." Su Yun seized on an impreciseness in Zheng Ren's speech and directly retorted.

Zheng Ren felt helpless; even casual chatting had to be like a debate, noting every detail—living like this, isn't it exhausting?!

But Su Yun definitely wouldn't feel tired; he enjoys it endlessly.

"Besides, nitroglycerin is taken wrong; it's basically poison. 'Medicine is three-part poison'—that saying isn't wrong. It's just that Master Xiao latches onto the word 'poison', keeps expanding it, spreading fear." Su Yun said, curling his lip in a cold smile: "When it's his turn, he simply forgets that saying about medicine being three-part poison."

"How could it lead to renal failure? Becoming a vegetative state—is that due to insufficient venous return?" Yan Zhangsen asked.

"Nitroglycerin releases nitric oxide, activating guanylate cyclase, increasing cyclic GMP in smooth muscle and other tissues, leading to dephosphorylation of myosin light chains, regulating smooth muscle contraction, causing vasodilation." Zheng Ren said: "Especially in peripheral vessels, leading to lowered blood pressure."

"This blood pressure reduction is meaningful; while dilating coronary arteries, it reduces peripheral load, allowing the myocardium some rest."

By this point, Yan Zhangsen already understood.

It must be drug overdose causing sustained low blood pressure, even shock-level pressure; prolonged cerebral and renal ischemia leads to renal failure and cerebral hypoxia.

"So rare—I never expected to run into this case." Zheng Ren shook his head and said softly.

"You're putting on a fake sympathetic act like a cat crying over a mouse." Su Yun said disparagingly: "Normally you don't take medicine and claim drugs are toxic; when you should take medicine you sneakily swallow it, and the dose is still huge—who do you blame for this?" Su Yun said disparagingly: "You should just go to the hospital and get proper treatment, but no—you insist on self-discharging. The Medical University Affiliated Hospital side says the medical records are still lying in the Medical Department, fearing something might happen."

"What was the outcome of the rescue?" Zheng Ren asked.

"I don't know; the people at the Medical University Affiliated Hospital are busy. I warned them this guy is an internationally known swindler, so they must preserve enough evidence. If they get bitten back, I estimate the Medical University Affiliated Hospital won't die but will at least lose a layer of skin." Su Yun said.

"The surveillance video of his first visit and self-discharge needs to be kept." Zheng Ren said: "No, I'm asking about the rescue outcome, not about later lawsuits."

"Every rescue, you first think about lawsuits—that's routine in the Emergency Department. You're still the Inpatient Chief of the ED; aren't you embarrassing yourself?" Su Yun looked at Zheng Ren, blew a breath, his forehead hair fluttering.

Zheng Ren shrugged, indifferently gazing out the window, not knowing what he was thinking.
