Chapter 2265: Chapter 1469

At nine in the morning, the corridor of the neurosurgery ward was tranquil and orderly. Yang Ping stood at the door of Lin Xiaoyu’s ward, his figure upright.

Weber and Manstein followed closely behind, both wearing neatly arranged white gowns, standing erect, their expressions solemn, carrying the unique rigor and prudence of doctors. Inside the ward, twelve-year-old Lin Xiaoyu was already prepared, half leaning against the headboard. Her hospital gown was pristine, her jet-black hair neatly combed, exuding a maturity beyond her years. Her mother stood by the bedside, holding a thermos cup, with a hint of restrained tension in her expression.

"Professor Yang." Lin Xiaoyu’s voice was clear, more confident than during last week’s follow-up, shedding some of the post-illness frailty.

"How are you today?" Yang Ping walked slowly forward, raising his hand to take the medical record folder at the head of the bed, his fingertips gently flipping through the pages. The medical record was clear and organized: the patient’s vital signs were stable, sleep quality was good at night, and she had consumed half a bowl of porridge and an egg in the morning without symptoms of nausea, vomiting, headache, or dizziness. All clinical indicators showed a steady improvement trend.

"I’m doing quite well. After yesterday’s MRI, Director Xu said that the necrotic areas inside the tumor have grown larger." Lin Xiaoyu spoke calmly, showing no childish fear, just a straightforward statement.

Yang Ping looked up at her, realizing that this twelve-year-old could so calmly utter this medically significant statement about her illness, indicating that Xu Zhiliang had already explained the condition to her in layman’s terms and that this little girl fully understood and calmly accepted the changes brought by the treatment.

This reminded him of Sisi, who, at that time, was only nine years old, yet her cognitive abilities far surpassed those of her peers.

"Are you scared?" Yang Ping asked softly.

Lin Xiaoyu lowered her eyes in thought for a moment, then gently shook her head, "Not scared. If the necrotic area is growing, it means the treatment is effective, right?"

A glint of appreciation crossed Yang Ping’s eyes. This wasn’t the fearlessness of ignorance; it was the bravery of recognizing the illness and making an active choice, which is fundamentally different.

"That’s right, it’s a clear sign of effective treatment."

At nine fifteen, the targeted drug infusion officially began.

Lu Xiaolu had already completed all preparations. The infusion pump, infusion lines, targeted agents, and a full set of emergency equipment were all arranged sequentially on the operation table, neatly and clearly, fully meeting the requirements of standardized clinical operations.

"Set the infusion rate." Yang Ping watched the equipment and spoke in a deep voice.

"Sixty milliliters per hour for the first thirty minutes; if no adverse reactions occur, increase to one hundred and twenty milliliters per hour, with a total infusion volume of two hundred milliliters." Lu Xiaolu responded precisely, the data firmly in mind.

"Begin."

The sterile tubing successfully connected to the PICC line in Lin Xiaoyu’s upper arm, and the transparent medication slowly dripped through the slender lines. The infusion pump emitted a rhythmic and subtle ticking sound, with each tick corresponding to one milliliter of liquid precisely flowing into the patient’s blood vessels.

Yang Ping stood in a corner of the ward, arms crossed over his chest, quietly observing. Weber stood beside him, while Manstein guarded the ward entrance, each person in their station, silent, their gazes entirely focused on the slender liquid column within the tube. The ward was silent to the extreme, wrapped gently in the rhythmic sounds of the equipment, enveloping the little girl on the bed.

Lin Xiaoyu slowly closed her eyes, her breathing even and deep, her long eyelashes resting still, peacefully resembling a deep sleep. Her mother sat by the bed, firmly holding her daughter’s hand, gently rubbing her thumb along the back of it, providing companionship and support in the kindest way.

The first thirty-minute observation window passed smoothly, with no fever, rash, chest tightness, or blood pressure fluctuations, or any adverse reactions. Lu Xiaolu immediately adjusted the infusion rate to one hundred and twenty milliliters per hour as per the standard procedure, the frequency of the dripping doubled, and the infusion pump’s beeping rhythmically accelerated, crisp and regular.

The various risks Sisi once faced now no longer exist. If it hadn’t been for Sisi being the "number one patient" back then, K Therapy could never have developed so quickly. Actually, the initial K Factor of K Therapy was also discovered in the culture box of Sisi’s tumor cells.

Weber gently nudged Yang Ping’s arm, slightly raising his chin to indicate the entrance of the ward.

Xu Zhiliang was standing outside the door, holding a tablet. Seeing Yang Ping looking over, he raised his hand to make a light gesture.

Yang Ping quietly walked out of the ward, following Xu Zhiliang to the doctor’s office. Xu Zhiliang placed the tablet on the desktop, pulling up yesterday’s MRI images, adjusting it to the highest brightness for easier observation of the details.

"The latest imaging results are out: necrotic area within the tumor is 4.5mm in diameter, an increase of 1.3mm from last week."

Yang Ping intently stared at the highlighted area on the screen. Last week it was 3.2mm, this week it’s 4.5mm, a single-week increase of forty percent, a change both intuitive and significant.

"How about the signal around the lesion?" Yang Ping inquired about the critical indicators.

"The peripheral low-signal ring boundary is more clear and regular," Xu Zhiliang traced an outline surrounding the lesion with his fingertip, his tone firm, "This is a typical sign of improvement, indicating that the drug precisely targets the tumor lesion, and the damage range of the normal tissue is gradually shrinking."

Yang Ping gazed for a long time at the bright area on the image, silent for more than ten seconds. The expansion of the necrotic area of the lesion, clearer boundaries, and formation of the surrounding low-signal ring indicate that the tumor cells are dying in large numbers.

Back then, Sisi experienced brainstem edema due to a large-scale death of tumor cells, posing a life-threatening condition, which Yang Ping quickly resolved with emergency relief surgery. After accumulating those experiences, no life-threatening conditions occurred again in the treatment of intracranial tumors with K Therapy.
