Description

A kind of Chinese medicine injection for the treatment of cancer

Affiliated technical field

The present invention relates to a kind of medicine for the treatment of cancer, specifically relate to a kind of Chinese medicine injection for the treatment of cancer.

Background technology

At present, cancer has become after cardiovascular and cerebrovascular disease, and the second largest killer of harm humans health shows that according to interrelated data the annual whole world has 7,000,000 people to die from cancer approximately.Cancer has been a kind of frequently-occurring disease, and with regard to present medical science level, the whole healings of cancer patient still are difficult to accomplish, but the generation of control cancer can be accomplished with the reduction mortality rate.Chinese medicine is of long standing and well established to the understanding of tumor.Aspect morbidity, various tumors due to illness machine are not quite similar, and say on the whole, think it mainly is positive QI-insufficiency, evil poison is taken advantage of a weak point, and causes the stagnation of QI, blood stasis, expectorant and hands over knot with fixed attention mutually, become lump for a long time and gradually, and the pathogen collection of crouching, the circulation of inevitable further retardance qi-blood-body fluid, consume vital essence, corrode the internal organs meridians, cause and effect links to each other, and deteriorated case is grown thickly, final threat to life.The traditional Chinese medicine of China has accumulated many valuable experience on tumor diagnosis and treatment.In fact, traditional Chinese medical science practice in several thousand is just as be equivalent to the once Preliminary screening of the large-scale cancer therapy drug that carries out from natural plants, animal, mineral and marine organisms, the Chinese medicine that these Preliminary screening are come out relends and helps modern technologies to carry out explication de texte, simulation modification and pharmacology and effect research, might develop some brand-new effective antitumor medicines fully, make the traditional Chinese medical science make bigger contribution the mankind's antitumor cause.The determination of treatment based on pathogenesis obtained through differentiation of symptoms and signs of the traditional Chinese medical science, treating both the principal and secondary aspects of a disease, equilibrium between yin and yang scheduling theory and method if can be fused in the Comprehensive Treatment of doctor trained in Western medicine to tumor rightly, also will promote the common raising of the traditional Chinese medical science and oncotherapy.

Summary of the invention

The object of the present invention is to provide a kind of Chinese medicine injection that multiple malignant tumor such as pulmonary carcinoma, the esophageal carcinoma, gastric cancer, hepatocarcinoma, cervical cancer is all had good efficacy.

The Chinese medicine injection of treatment cancer provided by the invention, this injection is prepared by following method:

(1) with the Caulis Marsdeniae Tenacissimae is raw material, add 8～12 times of amount 70～90% ethanol, merceration 0.5～24h refluxes 1～5 time, filters, medicinal residues are standby, merge alcohol extract, being evaporated to relative density is 1.08～1.18, leaves standstill, get clear liquid, ethyl acetate with 5～10 times of amounts divides 5～10 extractions, merges ethyl acetate extraction liquid, reclaims ethyl acetate to most, get thick paste, thin up leaves standstill, and gets the clear liquid molecular cut off and be 50000 and 3000 membrane ultrafiltration, ultrafiltrate is evaporated to relative density 1.10～1.15, and spray drying gets total glycosides extractive;

(2) medicinal residues add the water logging bubble of 6～8 times of amounts, decoct 2～4 times, merge decocting liquid, be evaporated to relative density 1.08～1.20, add ethanol and make and contain the alcohol amount and reach 20～25%, left standstill 12～72 hours, filter, filtrate adds ethanol precipitation again to be made and contains alcohol amount and reach 60～90%, left standstill 24～72 hours, and filtered, it is colourless that precipitation is washed till filtrate with ethanol, the water heating for dissolving that adds 5～7 times of amounts, add tannic acid liquid to nothing and precipitate till the generation, centrifugal, it is 1.15～1.20 that centrifugal liquid is evaporated to relative density, adding ethanol makes and contains alcohol amount and reach 70～80%, left standstill 24～96 hours, and filtered, precipitation is washed till no tannic acid reaction with ethanol, spray drying must contain the extract of polysaccharide;

(3) above-mentioned two kinds of extracts are mixed, add the injection water, after the heated and boiled, add active carbon, continue to boil, filtered while hot adds NaHSO in the filtrate ₃, EDTA-Na ₂, NaCl, propylene glycol is transferred PH to 7.0 with NaOH liquid, uses filtering with microporous membrane, gets finished fluid, embedding, sterilization, promptly.

Chinese medicine injection of the present invention has to eliminate the phlegm invigorates blood circulation, and the effect of blood stasis-eliminating and stagnation-dissipating is mainly used in the treatment of pulmonary carcinoma, also can be used for esophageal carcinoma, gastric cancer, and hepatocarcinoma, the treatment of multiple malignant tumor such as cervical cancer, curative effect is sure, have no side effect.

Below in conjunction with embodiment and pharmacodynamics test Chinese medicine injection of the present invention is further described.
