[0005] Advances in the treatment of lung cancer with Western medicine: Non-small cell lung cancer (NSCLC) accounts for more than 80% of lung cancer. In countries and cities, it is the first of various cancers, 65% of which are stage III and IV when they are discovered, often without surgical conditions, and the effect of radiotherapy is not satisfactory. Although chemotherapy is a systemic drug in drug treatment, in In the past 10 years, great progress has been made compared with the past. The emergence of a large number of effective new chemotherapy drugs and drugs with reduced toxicity has improved the curative effect and tolerance compared with the previous ones. However, NSCLC has the characteristics of high drug resistance and poor curative effect. , especially for stage IV patients with distant metastases, although chemotherapy is still the main treatment, how many cycles and time will be used, as well as the discomfort and pain brought to patients, and whether the two are "suitable" are the current oncologists , the patient's concerns

Abstract

The invention discloses an extractive of a compound formula of ophiopogon decoction and caper euphorbia seed and reed stem soup. The extractive is thick paste which is obtained by treating a compound formula of ophiopogon decoction and caper euphorbia seed and reed stem soup by a series of steps of water extraction, alcohol precipitation and extraction of cyclohexane and ethylacetate. The invention discloses a preparation method of the extractive and also discloses the application of the extractive in preparing a medicament for inhibiting H460 cell proliferation. The extractive of a compound formula of ophiopogon decoction and caper euphorbia seed and reed stem soup is characterized in that the extraction of the ethylacetate can obviously inhibit the growth of human lung giant cell carcinoma H460 and has no obvious influences on human normal cells, and the extraction has the effect of cell mediated cytotoxicity and can further separate and screen components and monomeric compounds forinhibiting the proliferation of the human lung giant cell carcinoma H460.

Description

technical field [0001] The invention relates to an extract of a combination of Maimendong decoction and Qianjinweijing decoction and its application. Background technique [0002] Lung cancer is one of the common malignant tumors in all countries in the world. It is the fastest growing among all malignant tumors. It is the main cause of human cancer death and is considered to be the most harmful malignant tumor to human health and life in the world today. About 3 million new cases are added every year in the world, and at the same time, more than 1 million people die of lung cancer every year. In my country, lung cancer accounts for the first place in the incidence and death of malignant tumors, with an annual incidence of 35 cases per 100,000 people and a 5-year survival rate of only 10%. Male lung cancer ranks first, while China ranks first in the world in terms of lung cancer and the absolute number of patients. According to some data, "China's lung cancer will account f...
