Fire from the nose

Introduction The nose is on fire, and Chinese medicine refers to symptoms such as inflammation, redness and swelling of the nose. Chinese medicine refers to exogenous wind and evil, which has stagnation and disease. Allergic rhinitis, Western medicine called immune hyperactivity, Chinese medicine is lung yin deficiency, impotence, and nose through the lungs, fire from the nose.

Cause

(1) Genetic factors

A family history of allergies is predisposed to this disease. Patients have a history of asthma, urticaria or drug allergy. In the past, this patient was referred to as atopic individual, and its ability to produce IgE antibodies in vivo was higher than that of normal people. However, in recent years, some authors have found that there is no significant difference in the incidence rate between twins and the general population.

(two) nasal mucosal susceptibility

Susceptibility arises from the frequent stimulation of antigenic material, but its susceptibility depends on the number of mast cells, basophils and the ability to release chemical mediators in nasal mucosa. It has been confirmed that the number of such cells in the nasal mucosa of patients with allergic rhinitis is not only higher than that of normal people, but also has a strong ability to release chemical mediators.

(3) Antigenic substances

The antigenic substance that stimulates the body to produce IgE antibodies is called an allergen. The allergen again enters the nasal mucosa and binds to the corresponding IgE to cause an allergic reaction. The allergens causing the disease are divided into two categories: inhalation and food according to the way they enter the human body:

Inhalation allergen

Inhale into the nasal cavity by breathing. Such allergens are mostly suspended in the air.

(1) Pollen

Not all plant pollen can cause disease. Only pollen that has a large amount of pollen, a wide area of vegetation, a strong allergen and spread with the wind is most likely to become an allergen. Pollen with allergenicity varies from region to region due to differences in vegetation species. For example, in North Europe, pollen is mainly birch and step grass; in North America, ragweed is dominant; in Japan, cedar pollen is dominant; in China, the area is broad, and the sensitized pollen in each region is not uniform. The northern area is dominated by wild artemisia pollen. Lord, but ragweed found in the north and south of the river should be taken seriously. In recent years, it has been suggested that with the continuous development of industrialization, the concentration of harmful substances such as sulfur dioxide in the air increases, and the protein structure of pollen surface suspended in the air can be mutated, so that the pollen that is not allergenic also has strong allergies. Originality. This may be one of the main reasons for the significant increase in morbidity. The types and contents of pollen in the air are significantly seasonal, and spring and summer and autumn are the peaks of pollen dissemination.

(2) fungi

It is widely distributed in nature and is mainly found in soil and spoiled organisms. Its hyphae and spores are allergenic, but spores are stronger. Spores can be widely spread by the wind, the amount in the air is sometimes higher than pollen, and the rural areas are higher than the city. The most common fungal species are the genus Monospora, Alternaria, Penicillium, Aspergillus and Saccharomyces. Among them, Mycobacterium aureum and Alternaria alternata have significant seasonality, and the number of spores in the air is mostly in summer. Indoor high temperature and dark moisture are conducive to fungal growth. The soil in indoor ornamental flower pots is also often a good place for fungi to grow.

(3) House dust mites

Is an arthropod arachnid. The adult size is generally 300 to 500 m. Mainly parasitic in all corners of the living room, among which the most dust in the bed, pillows, sofa cushions and so on. The sputum excrement, eggs, desquamation and its disintegrated limbs can all become allergens.

(4) Animal dander

Animal dander is one of the strongest allergens. Susceptible individuals can be sensitized if they are in contact with the animal for a long time. Nasal symptoms can be triggered by exposure to even a small amount of dander after sensitization. Animal dander that causes respiratory allergies mainly comes from animals that are in close contact with humans, such as domestic pets (dogs, cats), domestic dogs, cattle, horses, and sheep.

(5) feather

Feathers or bedding, pillows and feathers in clothing, and feathers from domesticated birds can be allergens.

(6) Indoor dust

It is one of the common allergens that cause perennial rhinitis. Its composition is quite complicated, and it is a hodgepodge of various substances, including animal, plant and chemical substances.

2. Ingestion allergen

Refers to allergens that cause nasal symptoms from the digestive tract into the body. The way of acting on the nasal mucosa is very complicated, and it is still unclear. Milk, eggs, fish, shrimp, meat, fruits, and even some vegetables can become allergens.

It is characterized by congestion or edema. Patients often have nasal congestion, runny nose, itchy nose, throat discomfort, and cough.

Differential diagnosis

Dry and itchy of the nasal mucosa: dry and itchy nasal mucosa, capillaries easily rupture, bleeding. This is a symptom of dry rhinitis. Chronic rhinitis sicca is generally thought to be caused by external physical or chemical stimuli, such as mechanical stimulation of long-term dust, effects of air overheating and excessive drying. The disease is a common occupational chronic rhinitis. It is characterized by dryness and discomfort in the nasal mucosa, less secretion, and the patient generally does not have runny nose. Because of the itching sensation in the nose, patients often dig their noses and cause nasal bleeding.

Red nose: The nose is the main external organ of a person in breathing. It moisturizes and purifies the air that people inhale from the outside world and is the first defense barrier for many diseases. The occurrence of many diseases can also be reflected from the nose. The normal nasal color is the nose, the mountain is bright, the nose is bright, and the nasal mucosa is red and moist. Abnormal red nose is also a pathological condition, indicating a potential disease.

With bloody pus snot: Sometimes when you lick your nose, you can see sticky pus and bloodshot. The causes of blood in the nose are many and complex, and it is necessary to diagnose according to different causes.
