Hematology
About me
After graduation, I have been working in the Hematology Department at Kaifeng Central Hospital, engaging in clinical work. I have gained certain clinical experience in common diseases in the field of hematology, and have also assisted other clinical departments in auxiliary treatments.
Proficient in diseases
Specializes in common diseases of hematology, such as leukemia, hemophilia, anemia, lymphoma, thrombocytopenia, tetanus, hypoglycemia, aplastic anemia, neonatal hemorrhage, vitamin deficiencies, and other autoimmune diseases.

The main cause of aplastic anemia is.
The causes of aplastic anemia are considered to be of three types: abnormalities in hematopoietic stem cells, abnormalities in the bone marrow microenvironment, and abnormalities in immune factors. Among these, abnormalities in immune factors play a dominant role. Therefore, most patients with aplastic anemia see some improvement after receiving immunosuppressive therapy clinically. However, there is a small subset of patients with aplastic anemia for whom immunosuppressive therapy is not effective, and the causes of the disease in these patients are not well understood and may be congenital, such as congenital dyskeratosis.
What causes aplastic anemia?
Aplastic anemia's exact causes are still not completely clear. Clinically, it is believed that immune dysfunction is a significant factor associated with aplastic anemia. Most cases of aplastic anemia can achieve good therapeutic outcomes through immunosuppressive treatment, which indirectly supports this view. However, some scholars believe that in aplastic anemia, there are patients for whom immunosuppressive treatment is ineffective. This suggests that other factors might exist, such as congenital anomalies in hematopoietic stem and progenitor cells, or abnormalities in the hematopoietic microenvironment, which may also play a role in the development of aplastic anemia.
What are the symptoms of aplastic anemia?
The symptoms of aplastic anemia include three main symptoms: firstly, infections; secondly, anemia; and thirdly, bleeding. Infections occur due to a decrease in white blood cells, especially neutrophils, resulting in poor resistance in patients making them susceptible to subsequent infections, including infections of the lungs, digestive system, urinary system, and skin and mucous membranes. Anemia occurs due to a reduction in red blood cells, causing symptoms such as dizziness, headaches, fatigue, reduced tolerance to physical activity, and poor appetite. A reduction in platelets significantly increases the risk of bleeding, especially when platelets are less than 20 times 10 to the ninth power per liter, which can lead to bleeding in the skin, mucous membranes, organs, and even cerebral hemorrhage.
Which is more severe, aplastic anemia or leukemia?
Aplastic anemia is not leukemia. Leukemia is characterized by more than 20% primary cells in the bone marrow being classified as leukemia. Aplastic anemia, on the other hand, is a bone marrow failure disease, characterized by a reduction in hematopoietic cells in the bone marrow, leading to a decrease in all blood cells. Aplastic anemia can be divided into acute aplastic anemia and chronic aplastic anemia. Acute aplastic anemia has a rapid onset, severe condition, and high mortality rate, while chronic aplastic anemia has a slow onset, longer disease history, and lower mortality rate. Treatment for acute aplastic anemia requires intensified immunotherapy or syngeneic complete match transplantation, whereas treatment for chronic aplastic anemia mainly involves promotive hematopoietic therapy.
Can anemia cause fever?
Patients with severe anemia may exhibit low-grade fever due to the severity of the anemia, where the fever generally does not exceed 38 degrees Celsius, mostly hovering around 37.5 degrees Celsius. Besides, if a patient with anemia develops high fever above 38 degrees Celsius, even reaching around 39 degrees Celsius, it is crucial to be vigilant about a possible secondary infection due to poor resistance from anemia. It is important to actively search for the source of infection, complete tests such as inflammatory markers, CT scans, and ultrasound imaging, and, once an infectious fever is suspected, to initiate aggressive anti-infection treatment.
Is leukemia cancer?
Leukemia is a cancer of the blood system. Based on the maturity of the tumor cells, leukemia can be divided into acute leukemia and chronic leukemia. Acute leukemia is further divided into acute myeloid leukemia and acute lymphoblastic leukemia, while chronic leukemia is divided into chronic granulocytic leukemia and chronic lymphocytic leukemia. As the name suggests, acute leukemia has a rapid onset, a shorter survival period, and treatment is more challenging. Chronic leukemia, on the other hand, has a slower onset, a relatively longer survival period, and the treatment results are comparatively better.
Can people with thalassemia not take iron supplements?
Thalassemia is a hereditary disease, classified as hemolytic anemia. Patients with thalassemia do not suffer from iron deficiency; rather, the anemia is caused by thalassemia itself, and iron supplementation is ineffective. However, if a patient with thalassemia also has concurrent iron deficiency anemia, then iron supplementation is necessary. During iron supplement treatment, it is also essential to conduct comprehensive examinations to ascertain the cause of the iron deficiency anemia and address the underlying cause.
Can carriers of thalassemia have babies?
Thalassemia carriers refer to individuals where one of the four genes is a pathogenic gene. Such patients can have children. However, it is advised that the other parent of the child be completely normal. Even if the other parent is completely normal, the child has a fifty percent chance of being completely normal and a fifty percent chance of also being a carrier of thalassemia. However, although they are carriers of thalassemia, they usually do not exhibit obvious symptoms of anemia, generally having no anemia or only very mild anemia.
Symptoms of leukemia
The symptoms of leukemia can be categorized into four main types: infections, anemia, bleeding, and organ infiltration. Infections occur due to a decrease in neutrophils, leading to poor resistance of the body and can trigger infections in various parts, such as lung infections, gastrointestinal infections, urinary system infections, etc. Anemia is caused by the growth of leukemia cells, which leads to limited erythropoiesis in the bone marrow, resulting in symptoms such as dizziness, headache, fatigue, poor appetite, and decreased tolerance to activity. Bleeding is due to a significant reduction in platelets in leukemia patients, making spontaneous bleeding more likely, which can manifest as bleeding from the skin and mucous membranes, organ bleeding, etc. Tumor infiltration can lead to abnormalities in other organs.
What medicine is used for aplastic anemia?
The main drugs used for aplastic anemia are immunosuppressants and cyclosporine. In addition to cyclosporine, low doses of hormones, androgens, and traditional Chinese medicine can also be used to stimulate bone marrow hematopoiesis. If the medication is effective, continue with oral administration; if ineffective, further consideration of bone marrow transplantation is needed. During the treatment process, it is necessary to regularly review the routine blood tests and, if necessary, provide support treatment with red blood cell and platelet transfusions.
