Recently, the Department of Hematology of Nanjing Children's Hospital, Fang Yongjun, chief physician and his team, after five years of research, found that the top three causes of children with acute lymphoblastic leukemia are home decoration pollution, parents smoking, drinking. That is to say, if the home decoration uses materials with excessive chemical elements such as formaldehyde and benzene, or fails to release the toxic and harmful gases after the decoration, it will move into a new home, which may cause hidden dangers to human health. "This study is very relevant for the study of childhood malignant tumors," Fang Yongjun said.
Case: Four-year-old child accidentally suffering from leukemia
The 4-year-old boy Dongdong (pseudonym) is an acute lymphoblastic leukemia patient. He was sent to hospital for treatment even if his family found an abnormality in Dongdong. His condition has stabilized and he has been discharged home. For the illness in Dongdong, at first, the experts could not figure out the specific reasons. Because there is no history of leukemia in his family members, genetic factors can be ruled out.
However, what is the reason for Dongdong to suffer from leukemia? Fang Yongjun told reporters that during their stay in Dongdong, medical staff learned that Dongdong had lived in the new house after renovation for half a year, and then was I was diagnosed with leukemia.
According to Dongdong’s mother, after their new home was renovated, Dongdong always felt uncomfortable, screaming for a while, and feeling pain for a while. Until one time, Dongdong cried and cried, bleeding nose, and only 8 days from the last nosebleed. When the couple sent their son to the hospital for examination, they found that the child's platelet abnormality was eventually diagnosed as leukemia.
Research: The probability of staying in the disease less than half a year increased by 4.76 times
It is understood that acute lymphocytic leukemia (ALL) accounts for 80% of children with acute leukemia, and the incidence rate is between 3 and 7 years old. Fang Yongjun said that leukemia is divided into acute lymphocytic leukemia and acute myeloid leukemia. Among them, acute lymphocytic leukemia, if diagnosed correctly and properly treated, 80-85% of children can live like healthy people for a long time; acute myeloid leukemia has as many as seven or eight subtypes, among which low-risk diseases More than half of the people, under the premise of proper treatment, can survive for a long time like healthy people, while the children with high-risk diseases have extremely high mortality, and the treatment in the clinic is single, and can only rely on bone marrow transplantation.
From 2007 to 2012, Fang Yongjun and his team have been investigating the cause of acute lymphoblastic leukemia. After investigating 570 children with this disease, 1000 normal children were searched for comparison. The results showed that the incidence of sickness in newly renovated rooms increased by 4.76 times within half a year.
It is understood that the research has been recognized by foreign counterparts. Fang Yongjun and his research team, "The Study of the Pathogenesis of Children with Acute Lymphocytic Leukemia," was published in the American journal Leukemia Research and the British journal Leukemia and Lymphoma, and was well received.
Cause: Smoking and drinking before pregnancy are also the main cause of illness
In addition, in the investigation, not only the pathogenesis of the disease was found to be related to decoration pollution, but also related to smoking and drinking before the parents were pregnant. It is understood that if the parents have not left their hands in the first half of pregnancy, and the wine does not leave, the chances of the child's illness increase by 3.93 times and 3.1 times respectively.
The reporter asked, in general, if a couple wants a child, how long does it usually take to quit smoking and alcohol before pregnancy? Fang Yongjun said that at least half a year. If parents do not smoke or drink alcohol, but some people in the family smoke, the influence of second-hand smoke is also great? Fang Yongjun said, yes. Even if the child has second-hand smoke in the living environment of the child after birth, the chances of her/he suffering from this leukemia will increase.
Trend: The incidence of leukemia is on the rise
"From a national perspective, the incidence of acute lymphocytic leukemia has shown an upward trend in recent years," Fang Yongjun said. According to epidemiological surveys, the incidence of the disease is increased by 4/100,000 per year. For the whole country, more than 10,000 new cases are added each year. In addition, the medical profession generally believes that the main factors of leukemia, in addition to family genetic factors, environmental factors mainly include: radiation factors, chemical factors, biological factors (caused by viral infection). Through clinical discovery, home decoration is a "culprit."
It is understood that the newly renovated house, if the formaldehyde exceeds the standard, it is easy to endanger human health. Formaldehyde is a colorless, highly irritating gas with high toxicity. Formaldehyde ranks second in the list of toxic chemicals in China. Formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance.
It is also known that formaldehyde is a Raw Material for the manufacture of synthetic resins, paints, plastics and rayon. Materials used in interior decoration or furniture, such as plywood, blockboard, medium density fiberboard, particle board, wall covering, wallpaper, chemical fiber carpet, paint, paint, adhesive, etc., contain formaldehyde to varying degrees or can be hydrolyzed to Chemicals of formaldehyde. These residual or decomposed formaldehyde will gradually release into the surrounding environment, and the longest release period can be more than ten years.
Glossary
Acute lymphocytic leukemia
Acute lymphocytic leukemia is a progressive malignant disease characterized by a large number of immature white blood cells similar to lymphoblasts. These cells can be found in blood, bone marrow, lymph nodes, spleen and other organs. They are malignant hyperplasia of leukemia cells in the hematopoietic organs such as bone marrow, spleen and liver. They can enter the blood circulation and infiltrate into organs of the whole body. Different degrees of anemia, bleeding, fever, and liver, spleen, lymphadenopathy and bone pain.
The onset of leukemia is rapid or slow, and children and adolescents have a rapid onset of illness. Common first symptoms include fever, progressive anemia, significant bleeding tendency, or bone and joint pain. Prolonged bleeding or excessive bleeding, skin bruising, bleeding gums, nosebleeds, subcutaneous hemorrhage, rash or skin lesions, joint pain, fever, gums, swelling, etc.
How to self-test the home environment
remind
How to judge whether the indoor environment of your home is harmful? The reporter learned that the public can judge from the following aspects.
1. The renovated room or the new home purchased has irritating odors such as glare and pungent, and the smell is not scattered for more than one year. When I wake up in the morning, I feel depressed, disgusting, and even dizzy.
2, family members are often prone to catch a cold.
3, although not smoking, and rarely touch the smoking environment, but often feel that the throat is uncomfortable, foreign body sensation, poor breathing.
4, family members often have skin allergies and other problems, and is mass-generating.
5, children at home often cough, sneezing, decreased immunity, newly renovated house children are not willing to go home.
6. The family has a disease, and after leaving the environment, the symptoms have changed significantly and improved.
7, the newlyweds are not pregnant for a long time, can not find the reason.
8. Pregnant women find fetal malformations in normal pregnancy.
9. After the new move or new decoration, the indoor plants are not easy to survive, the leaves are prone to yellowing and withering, especially some plants with strong vitality are difficult to grow normally.
Agricultural chemistry is based on soil, with plant nutrition as the center, fertilizer as means, comprehensive study of the relationship between the three, and finally achieve the aim of increasing crop yield. The methods include pot experiment, field experiment, agricultural chemical analysis, crop nutrition diagnosis, isotope technology, instrument analysis technology and electronic computer application technology.
Research and agriculture related chemical, including pesticide, plant growth regulator, fertilizer, compound fertilizer, herbicide etc.
