Embodiment 1

[0013] The preparation of embodiment 1 shikonin

[0014] Collect 5 kg of dry comfrey root, grind it, and extract it ultrasonically for 3 times with 95% ethanol, combine the extracts, concentrate under reduced pressure, degrease with petroleum ether ultrasonically, then extract with ethyl acetate, filter, extract the ethyl acetate extract under reduced pressure, and concentrate , dried to obtain the crude extract, the ethyl acetate crude extract was subjected to silica gel column chromatography 1400g (particle size 200-300 mesh, 10cm×20cm), petroleum ether-ethyl acetate (1:9~1:5) gradient elution , tracked and detected by TLC, combined, the eighth fraction was decompressed, concentrated to dryness, and rinsed with methanol to remove impurities. After vacuum drying, the shikonin powder was obtained, and the purity was greater than 95% as detected by HPLC, which was used for subsequent clinical and in vivo pharmacological experiments.

Embodiment 2

[0015] Example 2 Prevention and treatment effect of shikonin on leakage injury of chemotherapeutic drugs in rats

[0016] In this example, the experimental animals were: 60 3-month-old SPF male SD rats with a body weight of 180-200 g, provided by the Animal Experiment Center of the Second Military Medical University, and the certificate number is SCXK [Shanghai 2007-0003]. The main drugs are: doxorubicin hydrochloride for injection (referred to as doxorubicin, Shenzhen Wanle Pharmaceutical Co., Ltd., approved by the Chinese Medicine: H44024359), polysulfonic acid mucopolysaccharide cream (referred to as Xiliaotuo, Germany Sankyo Pharmaceutical Co., Ltd., Approval number: H20030014), soybean oil (Jiangxi Jinhaitang Medicinal Oil Co., Ltd., approval number: Ganshiyaozhunzi 20050003), shikonin (extracted from comfrey root), normal saline, 10% formaldehyde. The drug preparation method is as follows: 10mg of doxorubicin is diluted with 6ml of normal saline to a 1.67mg / ml solution f...

Embodiment 3

[0035] Example 3 Effect of Shikonin on Patient's Local Tissue Damage Caused by Chemotherapy

[0036] In the First Affiliated Hospital of the Second Military Medical University of the Chinese People's Liberation Army, 122 patients who underwent chemotherapy due to vascular injury caused by chemotherapy drug leakage and local tissue damage were randomly divided into groups. Appropriately and evenly rubbed on the damaged area, 60 people were in the shikonin treatment group, dissolved shikonin in a suitable matrix and evenly rubbed on the injured area. The drug was administered once a day, and the changes of the injury site were measured by visual observation and vernier caliper, and analyzed by digital photography combined with Image-Pro Plus 5.0 image analysis software. The results are shown in Table 4.

Abstract

The invention discloses application of alkannin and compositions thereof in preparing medicaments for preventing and treating vessel and local tissue injury caused by extravasation of chemotherapeutic agents. The rat in-vivo pharmacological research and clinical research show that the alkannin has obvious effects of treating the vessel and local tissue injury caused by extravasation of chemotherapeutic agents and promoting healing and can obviously shorten the time of eliminating the swelling of the local tissues and accelerate the healing of the local tissue injury, and also show that the alkannin and compositions thereof can be used for preparing the medicaments for preventing and treating the vessel and local tissue injury caused by the extravasation of the chemotherapeutic agents.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the application of shikonin and its composition. Background technique [0002] With the increasing incidence of cancer, the clinical application of chemotherapeutic drugs is becoming more and more extensive. Chemotherapy is one of the means of clinical treatment of various cancers, leukemia, and immune diseases. Extravasation of chemotherapy drugs is a relatively common complication. Most chemotherapy drugs have a strong stimulating effect on local tissues and can cause phlebitis. Some chemotherapy drugs such as vincristine can cause neurotoxic damage. After extravasation of chemotherapy drugs through intravenous injection, mild cases can cause mild erythema, local pain, swelling, and burning of surrounding tissues, and severe cases can cause surrounding tissue necrosis, skin ulcers, and deep structures such as tendon and joint damage. Taking active treatment measures after dr...
