Description
Technical Field
The invention belongs to the technical field of medicines, and particularly relates to a traditional Chinese medicine composition for treating skin itch as well as an extract and a preparation thereof.
Background
Pruritus is a dermatological condition in which there is only itching of the skin and no primary skin lesions. Generally, the skin itch is classified into general and limited types according to the extent and location of the skin itch. Among them, general pruritus is often found in adults, and pruritus usually begins at one place and gradually spreads to the whole body. It is often paroxysmal, especially at night, and persistent pruritus with paroxysmal aggravation in severe cases, and the onset and aggravation of pruritus can be promoted by drinking, coffee, tea, mood changes, pungent and pungent food stimulation, mechanical scratching, warm bedding and even some kind of suggestion. Scratch, blood crust, pigmentation, eczema, lichenification, pyoderma, lymphadenitis and lymphadenitis are often secondary to the disease.
Skin pruritus is a common disease and a common disease of skin diseases. The clinical manifestations are mainly the subjective symptoms of skin pruritus or pruritus, or accompanied by rash spots, blisters, desquamation and redness of skin, even desquamation and ulceration, and the part can be in a certain part or a larger range of the whole body. According to the theory of traditional Chinese medicine, skin itch is caused by the invasion of pathogenic factors such as wind, dampness, heat, worms and the like on the skin surface, and qi and blood in the surface are not harmonized. It is also caused by blood deficiency, wind dryness and malnutrition of the skin. The syndrome differentiation includes deficiency and excess, while excess involves wind-prevailing, damp-prevailing, heat-prevailing and parasites-prevailing; the blood deficiency is the main reason for deficiency. Wind, dampness, heat, parasites and blood deficiency may occur singly or in combination. In treatment, oral administration and external washing are combined, and the patients with mild symptoms are taken orally, while the patients with severe symptoms or stubborn symptoms and difficult healing are treated by external washing. Wind, dampness, heat, insect and blood deficiency are common pathogenesis of skin pruritus, but the common pathogenesis of the skin pruritus is wind. Skin pruritus is usually chronic disease, difficult to rapidly solve and easy to recur.

Clinical case efficacy analysis
The inclusion standard meets the clinical diagnosis standard of cutaneous pruritus in clinical dermatology, and patients only have paroxysmal cutaneous pruritus, no primary skin damage, large fluctuation of emotion and temperature difference before sleep, and aggravated situations when eating irritant food; the age is more than or equal to 60 years old; the syndrome differentiation of the traditional Chinese medicine is blood deficiency and wind dryness; the patients are not treated by drugs such as glucocorticoid within 1 month before entering the group. Eliminating the dysfunction of important organs; other types of skin disorders; a malignant tumor; a psychiatric disorder; drug allergy; the follow-up visit was lost.
98 patients with senile pruritus are divided into A, B groups by using a random number table method. Group a of 49, 28 men and 21 women; the age is 60-78 years, and the average (69.81 +/-3.36) years; the course of the disease is 4-22 months, and the average (10.49 +/-2.62) months. Group B49, 25 men and 24 women, aged 60-77 years, mean (69.69 + -3.25) years; the course of the disease is 5-25 months, and the average (10.63 +/-2.40) months. The difference was not statistically significant (P > 0.05) when compared between the two baseline data sets.
The intervention method comprises the following steps: group A is treated by oral administration of cetirizine hydrochloride tablet only, 10 mg/time and 1 time/d. The traditional Chinese medicine composition granules for treating skin itch in example 1 are additionally taken in the group B on the basis of the treatment of the group A, 1 bag of the traditional Chinese medicine composition granules is taken with warm water every time, 2 times a day, and 14 days are 1 course of treatment. The two groups are administered continuously for 2 treatment courses.
The curative effect standard is as follows: the pruritus areas before and after two groups of treatments, the pruritus frequency and the secondary skin damage symptom integral are evaluated according to the Chinese medicine new drug clinical research guiding principle. The pruritus area is less than or equal to 25 percent or the pruritus attack frequency is less than or equal to 2 times/d and 2 minutes is counted; the pruritus area is 25-50% or the pruritus frequency is 3-5 times/d and 4 minutes is counted; the pruritus area is more than 50 percent or the attack frequency is more than or equal to 6 times/d and is counted for 6 minutes; no skin damage meter 0 point; the skin is slightly dry, and a small amount of subcutaneous exfoliation and blood crust are counted for 2 points; moderate drying, and 4 points of flaky scale; severe dryness with obvious desquamation, with a papule and eczematoid change of 6 points. Two groups of curative effects were recorded, healing: the symptoms basically disappear, and the integral of clinical symptoms is reduced by more than 95 percent; the effect is shown: the clinical symptoms are obviously improved, and the symptom integral is reduced by 70 to 95 percent; the method has the following advantages: the clinical symptoms are improved, and the integral of the clinical symptoms is reduced by 70 to 30 percent; and (4) invalidation: the above standard is not met. The total effective is recovery + obvious effect + effective. The results are shown in Table 1.
The statistical method comprises the following steps: data were analyzed using SPSS 22.0 statistical software. Measure data to
Representing, adopting t test; the data of the counts are expressed in% by χ2And (6) checking. The difference is statistically significant when P is less than 0.05.
TABLE 1A, B comparison of clinical efficacy of two groups
| Group of | n | Recovery method | Show effect | Is effective | Invalidation | Total effective rate (%) |
| Group A | 49 | 10 | 16 | 13 | 10 | 79.59* |
| Group B | 49 | 15 | 21 | 11 | 2 | 95.92 |
Note: p < 0.05 compared to group a.
As can be seen from Table 1, the total effective rate of the treatment of the group B is 95.92%, which is higher than 79.59% of the group A, and the difference has statistical significance (P is less than 0.05), which indicates that the traditional Chinese medicine composition for treating skin itch has obvious curative effect on skin itch, especially on senile skin itch with blood deficiency and wind dryness.
