It was already a little late at this time. Only Yang Zheng and I sat on the sofa in the living room. He buried his head in his knees and inserted his hands deeply into his hair. His whole body curled up like a newborn silkworm cocoon.

Ren Pingsheng walked to his uncle with heavy steps and gently patted his back. Only then did he find that the man was trembling all over. Ren Pingsheng sighed and shook his uncle's shoulders and said, "Uncle, wake up, are you okay?"

Yang Zhenghe picked up his head from his knees. He took off his glasses, and there were tears left on the corners of his eyes. Obviously, he had just cried, his gray hair was messy like a grass nest. His graceful and handsomeness in the past disappeared, and the wrinkles on his face became deeper. At this time, his uncle was far more fragile than his age, and more like a helpless child.

"Xueping, Xueping is so bitter, but I can't save her." Yang Zhenghe murmured to himself.

"There is a way, there is a way." Ren Pingsheng murmured to himself. He was not just a comforting uncle.

Since he learned about his aunt's condition, he has tried his best to use the memory bank in his mind to find possible treatments from the memories of his previous life.

Although Ren Ping was not a doctor in his previous life and had not many friends with doctors, he read a lot and had a lot of information about various fields, especially high-tech information. Although it was not much related to his previous life's work, he browsed a lot in his spare time.

So he vaguely remembers in his mind that there is a treatment method for advanced non-small cell lung cancer, which is targeted therapy.

Targeted therapy is a new application of genetic testing technology in the field of treatment. As the name suggests, it is a type of therapy that targets unique to tumor cells (whether the gene is mutational) to attack them.

By interfering with the molecules needed to participate in the proliferation and differentiation of tumor cells, some drugs can directly lead to tumor apoptosis or indirectly stimulate the immune system to recognize and kill tumor cells.

To put it simply, the difference between targeted therapy and chemotherapy is that targeted therapy is a "guided missile" that aims at a small number of cells and will not harm other non-target cells; while chemotherapy is a carpet bombing that will eliminate "regardless of the enemy and ourselves". It will also harm innocent cells while killing harmful cells.

Compared with chemotherapy, targeted treatment is more accurate and targeted, which can be called "high efficiency and low toxicity". While exerting stronger anti-tumor activity, it reduces damage to normal cells, effectively prolongs the survival time of tumor patients, and also provides patients with a quality of life that is close to ordinary people.

Although targeted therapy has many advantages, there are not many people in China who really use it. The main reason is that it is inherently shortcoming and the most fatal shortcoming, that is, it is too expensive.

Take the lung cancer that Ren Xueping suffers from for example. The most common driver gene detected at present is the EGFR gene mutation.

In 2004, two American research teams announced that non-small cell lung cancer had a driver gene for epidermal growth factor receptor (EGFR) mutation. The gene of this receptor is located on the short arm of human chromosome 7. When this gene is mutated, normal cells will become cancer cells.

The incidence of mutations in the East Asian population, especially Chinese, is particularly high, accounting for about 30% of all non-small cell lung cancers, and Ren Xueping is one of these cases.

At present, the pharmaceutical industry has developed a targeted drug that can target EGFR genes. The molecular targeted drug Teresa (gefitinib tablets) was first launched by Asliton Pharmaceuticals in the UK.

This drug was just launched by the US FDA certification in 2003. It mainly blocks the conduction by inhibiting EGFR autophosphorylation, inhibits the proliferation of tumor cells, and achieves targeted treatment. It is the best treatment option for the treatment of advanced non-small cell lung cancer.

However, due to the restrictions on drug patent protection, currently only imported Asliton Pharmaceuticals is purchased in China. The price of a box of 10 tablets is about 5,000 yuan.

According to the method of taking one course of treatment (one tablet per day), it costs 15,000 yuan per month, and 180,000 yuan per year, which is already the down payment for a house.

Not to mention that the Xiaokang family cannot afford it, even Xiaofu, who has a little money, will go bankrupt, let alone Ren Xueping's family who only relies on their salary income. So after listening to Ren Pingsheng's introduction, the little hope that had just been ignited was instantly shattered.

In order to alleviate the pain of his beloved wife, Yang Zhenghe not only used up all the savings in the family, but also borrowed a lot of debts from relatives and friends, and even sold the houses that were still repaying the loan to the market. If the second-hand housing market was not in a recession this year, his aunt's family would not even be able to save this house.

Yang Zhenghe obviously had done his best and had already ended his life, but he was still unable to save his lover. Ren Pingsheng could feel his pain and despair. There was nothing more heartbreaking than watching his lover die while he was powerless.

"Uncle, don't worry, let's find a way together. Auntie will have a good appearance and will get better." Ren Pingsheng seemed more mature at this time, and he comforted the elder in front of him softly.

"Jiangren? No, it's all my fault. I have implicated her. I love myself more than I love her. I can't let go of my self-esteem and disdain to fight for benefits. As a result, I have no ability to help her and can only watch her suffer."

Yang Zhenghe grabbed his hair hard, as if he wanted to punish himself by scratching his hair.

"Xueping and I have suffered all their lives, because of me..."

Looking at Yang Zhenghe's words and actions, Ren Pingsheng was speechless. This was the first time since his reincarnation that he witnessed the cruelty of the real world with his own eyes.

As my uncle said, if their family is rich, they can get the best treatment for their aunt.

If their family is very powerful, they can also arrange the best medical resources for their aunt.

If you have no money and no power, you can only watch your relatives die under the torture of illness.

He also remembered that if he married Zuo Xiaoxiao in his previous life, Zuo Xiaoxiao would also get seriously ill one day, and he would definitely fall into the situation of Yang Zhenghe today, because Ren Pingsheng in his previous life was like Yang Zhenghe, and he had no ability to save his lover.

In this way, Zuo Xiaoxiao left herself in her previous life, which was a better choice for each other.

But everything in front of him is different. Ren Pingsheng is a time traveler who is reborn with memories of his previous life. He will not allow all this to happen. He not only wants to save his love with Zuo Xiaoxiao, but also save his aunt and uncle, and save all those he values.
