Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine technology and relates to a traditional Chinese medicine composition for treating thromboangiitis obliterans. Background Technology

[0002] Traditional Chinese medicine (TCM) considers thromboangiitis obliterans (TAO) to be a limb arterial embolic disease caused by non-invasive vascular complications. The onset is characterized by periodic attacks followed by periods of remission. Clinically, the dynamic changes of the disease are very obvious, generally manifesting as acute activity and remission / improvement. In treatment, staged diagnosis is extremely important. During the acute active phase, vascular complications are active, the vascular intima is damaged, blood viscosity increases, and straight thrombi continuously form. Its pathological characteristics can be summarized as "inflammation leading to thrombosis." TCM diagnosis is "due to pathogenic factors causing obstruction," which can be caused by external pathogens such as heat and dampness invading the collaterals, leading to stagnation of qi and blood, obstruction, and various "stasis" symptoms. In this stage, "pathogenic factors" dominate, and treatment must focus on "eliminating pathogenic factors," either by clearing heat and cooling blood, or resolving dampness and detoxifying. Once the pathogenic factors are eliminated, new ones will not form, and the disease will be difficult to control. This is because "stasis" is a pathological product of pathogenic damage to the collaterals; if the pathogenic factors are not eliminated, new ones will continuously form, making the condition difficult to control. The pathological mechanism of this disease is mainly the stagnation of qi and blood, and obstruction of blood vessels. Among the pathogenic factors of thromboangiitis obliterans, external factors include exposure to cold and dampness, improper diet, trauma, and poisoning. Internal factors include congenital deficiency, spleen and kidney yang deficiency, liver and kidney deficiency, and emotional distress, all of which lead to obstruction of the meridians. Cold causes contraction; when the meridians are exposed to cold, they spasm and contract, and blood congeals. After exposure to cold, yang qi cannot reach the limbs, resulting in poor blood circulation and stagnation. Obstruction causes pain, and with prolonged illness, both qi and blood become deficient, leading to malnourishment of the limbs.

[0003] The *Ling Shu* (Spiritual Pivot), in its chapter on carbuncles and boils, states: "When the *ying* and *wei* (nutritive and defensive qi) stagnate in the meridians, the blood becomes stagnant and cannot flow. When it cannot flow, the *wei* qi also becomes obstructed and cannot circulate." Liu Huijie believes that blood stasis plays a dominant role in the pathogenesis of this disease. In summary, its pathological mechanism can be mainly summarized as: cold-dampness obstructing the meridians, blood stasis, damp-heat descending, intense heat toxin, and deficiency of both qi and blood. The *Su Wen* (Plain Questions) chapter on Bi syndrome points out that "pain is caused by excessive cold qi; pain arises from cold." The *Su Wen* chapter on pain states: "Cold qi enters the meridians and stagnates, becoming stagnant and unable to flow. If it lodges outside the vessels, blood is scarce; if it lodges inside the vessels, qi is obstructed, hence the sudden pain." In its later stages, this disease is characterized by damage to tendons and bones, and deficiency of both qi and blood. The lesions mainly occur in the blood vessels and are more common in young and middle-aged male patients. Summary of the Invention

[0061] Calculated according to the human dosage, assuming the human weight is 60 kg, the rat dosage is 6.3 times the human dosage, and the crude drug dosage for rats is 71.19 g / kg.

[0062] 2 Experimental procedure

[0063] Take 90 rats and randomly divide them into a model group, an Example 1 group, an Example 2 group, an Example 3 group, a Comparative Example 1 group, a Comparative Example 2 group, a Comparative Example 3 group, a Comparative Example 4 group, and a Comparative Example 5 group, with 10 rats in each group. After the rats were anesthetized, they were fixed in the supine position. The left lower groin was used as the surgical site, the hair was removed, and it was disinfected. A longitudinal incision was made at the midpoint of the groin to expose the femoral artery sheath, and the femoral artery at the upper end of the superficial epigastric artery was dissected. The proximal end of the femoral artery was blocked with an arterial clamp to stop blood flow. 0.1 mL of 7 g / L sodium silicate solution was injected distally 1 cm below the arterial clamp, and the puncture site was sealed with medical glue. After 1 minute, there was no bleeding in the femoral artery, and the skin was sutured. After the operation, it was disinfected to prevent infection. On the second day after modeling, except for the model group, the rats in the other groups were given the corresponding drugs by gavage, and the model group was given distilled water by gavage for 30 consecutive days.

[0064] Another 10 normal rats were taken, injected with normal saline into the femoral artery and given distilled water by gavage as the sham operation group.

[0065] 3 Detection indexes

[0066] 3.1 Lesion score of the affected limb of rats

[0067] After establishing the rat model, the changes in the left hind leg of the rats were observed daily. After the drug treatment ended, the overall score was calculated, and the criteria were as follows:

[0068] Level 0: No change in overall appearance;

[0069] Grade I: The lesion is limited to the toenail;

[0070] Grade II: The lesion is limited to the toes;

[0071] Grade III: Lesions are limited to the toes and claws;

[0072] Grade IV: Lesions extend beyond the ankle joint and below the knee joint;

[0073] Grade V: The lesion has progressed above the knee joint.

[0074] 3.2 Detection of biochemical indicators in rats
