After the ore is gone, it is the turn of the carpenter, who is not a carpenter, but a person who supports the mine with wood. When the ore from the explosives is removed, a space is enlarged in the mine. This space must be stable, otherwise a mine collapse could occur. The carpenter's task is to prevent collapse accidents by erecting wooden frames.

The carpenters first used long iron rods to stir around the rock walls of the blasted space and through the cracks in the stones at the top of the mine, knocking down some loose rocks or ores that might fall off, and then using three long, thick, and strong wooden stakes that were cut into a rectangular shape to build a gate-shaped bracket to firmly support the top and sides of the mine.

The stakes are very tight and strong, and they are made of the same material as the railroad sleepers used to lay the railway, and they are just as strong. However, due to various reasons such as the emergence of substitutes and the avoidance of wood waste, sleepers basically withdrew from the stage and were replaced by cement sleepers. However, due to the particularity of the underground environment and the nature of the wood swelling when exposed to water, this kind of supporting wood has been used until now. The wooden shelves that have been erected are expanded by moisture, which will support the mine more strongly. And this wood is also not perishable.

The end of the carpentry work represents the end of a small cycle of underground mining. After that, it was the turn of the rockmason.

The mined ore is transported to the concentrator workshop, where after crushing, screening and sorting, the iron ore without doping with rocks is transported to the blast furnace together with coke and other white stones and catalysts.

In the big walnut iron mine, there are two hardest types of work, one is to endure the high temperature and high risk of the blast furnace workers in the ironmaking workshop, they not only have to endure the high temperature, but also worry about the risk of blast furnace accidents and the risk of molten iron spilling.

The other most difficult type of work is the rock work engaged in by Chen Nianzhong, which not only belongs to underground operations, but also belongs to dust operations. Although the high-pressure water of the rock drill absorbs most of the dust, a small amount of dust floats in the air and is sucked into the body by the rock worker.

Underground operations and dust operations, both of which belong to the special types of work classified by the state, can be retired early. And rockworking has both, which shows that it is not easy to rock working.

Due to frequent inhalation of dust, almost all of the rock workers have major or minor lung diseases, and Chen Nianzhong has two rock workers who died of lung cancer.

Chen Ziyang looked at the "suspected Ca lung" on the examination results and frowned, but Chen Nianzhong persuaded him: "It's okay, son, isn't this silicosis, it's a big deal to be guilty, it's not a big deal." ”

Chen Nianzhong has no education in his life, most people of that age are like this, Chen Nianzhong does not understand that the "Ca" in "Ca lung" is the meaning of cancer in English, he only knows ABC in English, thinking that the C in Ca lung refers to silicosis. Chen Ziyang didn't explain to his father, after all, there is no diagnosis now, don't let your father worry about it first, let's talk about it when it is diagnosed.

Linhai City is a county-level city, and the medical level is really very limited, under the advice of a friend and Chen Ziyang's insistence, Chen Ziyang led Chen Nianzhong to Beijing for examination.

In Peking University Hospital, Chen Nianzhong's disease was diagnosed, but it was not lung cancer as Chen Ziyang thought, but stage III lymphoma B. Chen Ziyang inquired and learned that the degree of cancer is divided into four levels, one to four, and each level is divided into two levels, AB, a total of eight grades, representing the severity of cancer.

Stage A is the mildest disease, and Stage 4B is the most severe, so it can be said that the cancer has progressed to Stage 4B, and you can go home to eat and drink and wait for the last few months. And Chen Nianzhong's stage 3 lymphoma B has reached the sixth level.

With the introduction and help of Chen Ziyang's Beijing classmates, Chen Nianzhong came to Beijing West Cancer Hospital to prepare for treatment. There are two good cancer hospitals in Beijing, East Cancer Hospital and West Cancer Hospital, among which West Cancer Hospital has the best treatment for lymphoma.

In the 11th-floor lymphoid oncology department of the West Cancer Hospital, Chen Ziyang found a trace of comfort. In the words of the doctor, having lymphoma is a blessing in misfortune. They all have cancer, of course, unfortunately, but because of the low degree of malignancy and high cure rate of lymphoma, it is the best and easiest to cure among all cancers, and because of this, lymphoma is generally not called lymphoma, but lymphoma.

There are two types of lymphoma, Hodgkin and non-Hodgkin. Among them, the Hodgkin type is the easiest to cure, and the non-recurrence rate can reach 80% to 90% within five years. The non-Hodgkin type can be subdivided into more than 30 types, and the cure rate is relatively low, reaching 50%-70%. Chen Nianzhong has one of the non-Hodgkin-type lymphomas, which is not too easy to treat, but it is not difficult to treat.

There is a specific targeted drug for Chen Nianzhong's non-Hodgkin-type lymphoma, which can greatly increase the effect of chemotherapy drugs, but the disadvantage is that this drug is very expensive, and it is an imported drug, which cannot be reimbursed by medical insurance. A course of treatment requires one injection, and the price of one injection is 25,000 yuan.

Originally, Chen Nianzhong did not agree to the treatment, because in the eyes of his generation, having cancer is empty of people and money, it is better to give up the treatment, and leave some money for the child, after all, the mine has stopped production now, and he is so old, he can't live for a few more years, and it is worth it for more than 60 people.

But Chen Ziyang resolutely disagreed, if it can be cured, it must be cured. After further discussion with the doctor, I learned that even if this targeted drug is not used, the recurrence rate of Chen Nianzhong will be very high within five years after treatment, and it is very likely to be cured if the drug is used.

Governance, must be cured, must be well treated. It is said that it is difficult to buy an inch of time, and now is the time to spend money to buy time. At Chen Ziyang's insistence, Chen Nianzhong began hospitalization.

Because the lymphatic system is spread throughout the body, chemotherapy is usually used for lymphoma. Chemotherapy is followed by radiation therapy for a very small number of tumors that are still swollen after treatment, and many patients do not require radiotherapy.

After so many years of research and treatment examples at home and abroad, the chemotherapy regimen for lymphoma has been very fixed. For patients who were found relatively late, had more diseased lymph nodes, and were more seriously ill than Chen Nianzhong, a stereotyped intensive treatment plan was adopted. Twenty-one days is a cycle, first targeted drugs, then three days of chemotherapy drugs, and then discharged, and on the eighth day, another injection of chemotherapy drugs in the outpatient clinic, and the course of treatment is over. After that, wait until day 22 before starting the next cycle of treatment.

In this way, Chen Ziyang accompanied his father to start the struggle against the disease.
