Abstract

An injection for treating solid tumor such as thyroma, liver cancer, etc. is prepared from urea (CH4N2C), sodium chloride (NaCl) and diluent. Its advantages include simple therapy, high effect and less complications.

Description

A kind of medicine for the treatment of solid tumor by injection

Technical field

The present invention relates to a kind of treatment solid tumor, especially medicine of solid tumor such as thyroid tumor, hepatocarcinoma that adopts injecting method to use.

Background technology

The main means of treatment tumor have excision, radiotherapy, chemotherapy etc. at present, operation is better for the tumor effect that does not have in early days diffusion, but tumor cell can escape into growth and breeding at a distance by the blood diffusion in the operation technique, existing metastatic tumour operative effect is bad, must cooperate radiation and chemotherapy.But radiotherapy, chemotherapy are difficult to kill tumor inside center cancerous cell, also are difficult to annihilate simultaneously the cancerous cell of pernicious transfer, and be very big to the loss of health, and general patient is difficult to bear, even can not be completed full course of therapy.In addition, radiotherapy, chemotherapy reduce body's immunity, and tumor cell can produce drug resistance to chemotherapy simultaneously, and can cause new factors such as carcinogenic factor after the radiotherapy, and its curative effect is also unsatisfactory.

Summary of the invention

Purpose of the present invention just is to provide a kind of treatment of injection such as the medicine of solid tumors such as thyroid tumor, hepatocarcinoma, with overcome operation, chemotherapy, the radiotherapy in the treatment method is existing causes adverse effect to human body, various defectives such as tumour inhibiting rate is not high, Therapeutic Method complexity.

The objective of the invention is to be realized by such compositions: said composition comprises carbamide (CH ₄N ₂C), sodium chloride (NaCl) and dilution use solvent, contains 0.6-0.7 in every ml soln of being formed and restrain carbamide, 0.16-0.18 restrains sodium chloride.Employed dilution solvent is general normal saline or the distilled water that uses clinically.The treatment volume is 1cm ³The injection consumption of solid tumor be 0.25-0.35ml.Every day or every other day the injection once, the injection site is an affected area.

For making things convenient for depositing and making of medicine of the present invention, the medical carbamide (purity 99%) and the medical sodium chloride (purity 99%) of solid, shaped can be pressed carbamide 1.8-2.1 gram, the ratio branch of sodium chloride 0.48-0.54 gram installs in the cillin bottle, when actual clinical is used, reuse normal saline or distilled water diluting become the solution of 3ml, and getting it filled by dosage then is injected directly into affected area.

The present invention also can add medical solid potassium chloride, the 15-20 milligram lignocaine of 15-20 milligram in every milliliter injection, with the further increase curative effect and the patient's that releives misery.

Carbamide is as diuretic in pharmacopeia and the pharmacology, dehydrant, and keratin-lytic agent is applied to clinical intracranial hypertension cerebral edema, glaucoma hypotensive effect and heart characteristic of disease edema diuresis.Injection in the high concentration urea, sodium chloride tumor body can cause inflammatory cell infiltration in the tumor, and tumor cell generation bland necrosis reaches the kill tumor effect, does not have chemotherapy, and radiotherapy suppresses hemopoietic function of bone marrow and immunologic function side effect.The most important thing is: by clinical treatment thyroid tumors 300 example statistics, cure rate reaches more than 94%, none routine recurrent laryngeal nerve, and complication such as parathyroid injury take place; Reach the white mouse hepatocarcinoma that do the Jiangsu Province Medicine Primary Institute, sarcoma S-180 animal pharmacological test result: tumour inhibiting rate shows that all the present invention has obvious tumor-inhibiting action between 41-45%.Satisfied except clinical effectiveness, safety does not have outside secondary the work, the present invention also avoided leading to complications after the operation and the scar after the operation influence attractive in appearance.But all out-patient treatment of patient, method is simple.

The specific embodiment

The present invention will be further described by the following examples.

Compound method: select the medical carbamide powder of analytical pure (99%), sodium chloride for injection powder for use, the ethanol heating for dissolving that adds 50% (V/V) after medical potassium chloride of analytical pure (99%) and lignocaine are mixed in proportion, filter with the vertical soluble glass funnel of 4#, filtrate is put in the enamel basin, be placed on 50 ℃ of thermostatic drier inner dryings, aseptic subpackaged in cillin bottle, close plug gland.During use, be mixed with 3ml solution with distilled water.

One, the acute toxicity testing of embodiment is as follows:

Get body weight in the healthy Kunming mouse male and female half and half of 20 ± 1 grams, press solid medicated powder (g): mice body weight (kg)=dosage intravenous injection in 2: 1, in 30 seconds, inject and finish, press solid medicated powder (g): mice body weight (kg)=dosage intramuscular injection in 5: 1, in 30 seconds, inject and finish, animal activity in the week after the administration, feed are normal, and respectively organizing body weight after the week obviously increases, and does not see drug-induced unusual reflection.Mice does not have death in one week, and the mice that survives 7 days is dissected, and it is no abnormal to observe its main organs.Two, the tumour inhibiting rate experiment is as follows:

1, experiment material: select the strain of S-180 tumor, liver-cancer solid tumor strain, the healthy Kunming mouse male and female dual-purpose of 20 ± 1 grams.

2, method: select the vigorous no diabrosis of tumor growth, tumor-bearing mice in good health takes off white execution, and iodine disinfection skin is shelled tumor under light bacterium condition, adds sterile distilled water in 1: 3 ratio.Make cell suspension with Potter-Elvehjem Tissue Grinders, in axillary fossa subcutaneous vaccination 0.2m1.Inoculate random packet after three days, in view of the experimental subject volume weight all less, can't be by the theoretical amount administration, every group of injection after will diluting by 0.05ml dosage is expelled to every mouse tumor body part, once a day, also having one group is the blank sample, once a day at the distilled water of tumor body local injection equivalent, weighs after continuous three days, the tumor piece is peeled off in dissection, claim tumor heavy, be calculated as follows tumour inhibiting rate, and take statistics is handled.

Tumour inhibiting rate surpasses the requirement that 49% medicine just meets national medicine for treating tumor thing, and above result shows that this compositions has the effect of good curing tumor.After having added potassium chloride, tumour inhibiting rate more has tangible rising.Three, clinical experiment is as follows:

Treatment thyroid carcinoma 300 example is observed: women's 242 examples wherein, male's 58 examples, age 12-78 year, 42 years old mean age, diameter of tumor 2-6cm, average 4.1cm.Major part is diagnosed as thyroid carcinoma through B ultrasonic, and it is that thyroid volume increases damaged lump cold nodule, cool tuberosity, warm nodule that radioactivity is explored diagnosis of scans.Case is divided into 6 groups, every group 50 example.

Therapeutic Method: patient gets seat, and patient's left hand is touched and thyroid tumor enclosed mass and with the fixing enclosed mass of forefinger, middle finger, partly sterilised, and the right hand is held syringe and is punctured, and through subcutaneous, throat flesh liquid medicine injection to the tumor, the next day, inject once, and 5 times is a course of treatment, 1cm ³The injection consumption of tumor is 0.3ml.Gross tumor volume=(the wide * of long * is thick) * 0.5.

Each embodiment is diluted to the solution for later use of 3ml with normal saline.Criterion of cure: neck region lump disappears or the following cicatrix scleroma of 1cm diameter after 3 months, and softening gradually, and scleroma disappears, painless, no sense of discomfort.Therapeutic effect is:
