Description

Composition and granules for improving bone marrow suppression after chemotherapy and preparation method

Technical Field

The invention relates to the field of traditional Chinese medicines, and in particular relates to a composition and granules for improving bone marrow suppression after chemotherapy and a preparation method thereof.

Background

The post-chemotherapy myelosuppression generally refers to the decrease of hematopoietic function of bone marrow, the decrease of activity of blood cell precursors in bone marrow, and the decrease of peripheral blood trilineage cells, especially the decrease of granulocytes in patients after chemotherapy. Myelosuppression delays the progress of chemotherapy and may lead to serious complications that endanger life, and studies of myelosuppression after chemotherapy have received much attention. Currently, rhG-CSF (short for short-acting leukogenic agent) or PEG-rhG-CSF (short for long-acting leukogenic agent) is mainly used for treating bone marrow suppression after chemotherapy in clinic. The short-acting whitening agent or the long-acting whitening agent has adverse reactions such as fever, muscle bone joint pain and the like after being used, wherein the short-acting whitening agent has short half-life period, needs repeated medication and large clinical dosage, the long-acting whitening needle has high price, and part of areas are not brought into medical treatment, and the use of the drugs is limited to a certain extent under the conditions. Therefore, finding more effective therapeutic drugs is currently the focus of relevant research.

The traditional Chinese medicine has a good effect of improving the bone marrow suppression after chemotherapy, and has a great potential. The formula consists of seven traditional Chinese medicines including semen cuscutae, herba epimedii, glossy privet fruit, medlar, astragalus root, bighead atractylodes rhizome and caulis spatholobi, and has the effects of tonifying kidney, producing marrow, strengthening spleen, tonifying qi and enriching blood and promoting blood circulation. The clinical application has good feedback for patients, stable marrow generating effect and high safety. In order to protect the exclusive rights of the invention creation, respect the labor achievement, promote the development of science and technology and economy, and promote the popularization and application of the invention creation, a patent application is provided for the production and application of the He shi myelogenesis formula.

The traditional Chinese medicine theory does not have a concrete concept of bone marrow suppression, but the clinical symptoms of patients with bone marrow suppression, such as inappetence, hypodynamia, shortness of breath, sweating, intolerance of cold and the like, are combined for judgment, and the patients with bone marrow suppression mostly belong to the categories of consumptive disease and blood deficiency in the traditional Chinese medicine. Furthermore, most chemotherapy drugs are strongly toxic and cold with severe fever, and they compete with healthy qi directly in the middle-jiao to disturb qi and blood in the middle-jiao, and may involve the spleen and kidney, damage essence and blood, and consume yin and blood in darkness. The classic theory of traditional Chinese medicine considers that the spleen governs transportation and transformation to be acquired root and distributes the essence of food, which are the source of qi and blood generation and transformation, and all bones of the five viscera are all supported by the spleen. Kidneys are the innate root, governing bone and producing marrow, and storing essence and producing blood. The spleen and stomach are weak, the functions of the spleen and the stomach are disabled, food essence cannot be normally distributed, and qi and blood are generated and generated without source; when kidney essence is deficient and marrow sea is empty, essence and blood are not generated. The traditional Chinese medicine has rich experience in treating the deficiency diseases, for example, the theory of Liang vacuity Yuan Jian clearly summarizes the essence of treating deficiency with three causes, namely lung, spleen and kidney, lung is the day of five internal organs, spleen is the mother of skeleton, kidney is the root of life, lung, spleen and kidney are treated, and deficiency is treated with the principle . The traditional Chinese medicine fully implements the treatment concept, and clinical treatment mostly applies classic tonifying products such as four-ingredient decoction, four-monarch decoction, eight-treasure decoction, ZUOGUI pill, YOUGUI pill and the like, and finally can obtain better clinical curative effect by taking lung tonifying, spleen strengthening and kidney tonifying methods.

Aiming at the problem that the treatment price is high and no marrow suppression concrete concept exists in the traditional Chinese medicine theory in the prior art for improving the marrow suppression level after chemotherapy, the need of finding an improvement composition which is low in price and can realize the marrow suppression after chemotherapy is very necessary.

The dodder seed is pungent, sweet and mild in nature and has the effects of entering liver, kidney and spleen channels, tonifying liver and kidney, securing essence and reducing urination, preventing miscarriage, improving eyesight and stopping diarrhea; herba epimedii enters liver and kidney meridians, has the main effects of tonifying kidney yang, strengthening muscles and bones and dispelling wind-damp, and is recorded in compendium of materia medica: ' producing essence and replenishing marrow, nourishing blood and tonifying yang, strengthening tendons and bones, treating all deficiency syndromes, deafness and dim eyesight, dizziness and dysentery; the glossy privet fruit is sweet, bitter and cool in nature and flavor, enters liver and kidney channels, and has the effects of nourishing liver and kidney, improving eyesight and blackening hair; the medlar is sweet and neutral in taste, enters liver and kidney channels, has the efficacies of nourishing liver and kidney, replenishing vital essence and improving eyesight, is a good medicine for nourishing liver and kidney, nourishing blood and replenishing vital essence and improving eyesight, and is recorded in the book of materia medica Jing Jizhu: medlar can tonify essence and qi and strengthen vagina; radix astragali is sweet in nature and taste, slightly warm, and has the effects of invigorating qi, invigorating yang, consolidating superficial resistance, arresting sweating, inducing diuresis, relieving swelling, promoting fluid production, nourishing blood, activating stagnancy, relieving arthralgia, expelling pus, healing sore, and promoting granulation, and is recorded in Ben Cao Yao (herbal remedy): "Shengxue, Sheng Jie, pus discharge and interior support, Sheng Yao for treating sores and abscess". Bighead atractylodes rhizome, which is sweet, bitter and warm in nature and flavor, enters spleen and stomach meridians, has the effects of strengthening spleen and replenishing qi, eliminating dampness and promoting diuresis, arresting sweating and preventing miscarriage and is an essential spleen-invigorating medicine, is suitable for patients with no pimple and yang deficiency and no heat; caulis Spatholobi, being bitter in flavor, sweet and warm in nature, enters liver and kidney meridians, and has effects of activating blood and replenishing blood, regulating menstruation and relieving pain, and relaxing tendons and activating collaterals. In the formula, the dodder seed and the epimedium herb are used as monarch drugs for tonifying kidney yang, the glossy privet fruit and the medlar are used as minister drugs for nourishing kidney yin, the astragalus root and the bighead atractylodes rhizome are used as assistant drugs for tonifying spleen and stomach and protecting postnatal, and the chicken blood and rattan are used as guide drugs for replenishing blood and promoting blood circulation. The whole formula has the effects of tonifying kidney and producing marrow, strengthening spleen and tonifying qi, and enriching blood and activating blood. The clinical application has good feedback for patients, stable marrow generating effect and high safety. In the previous research work, the marrow-producing prescription is researched by using a network pharmacology means, and the result shows that the dodder, the epimedium herb, the glossy privet fruit, the medlar, the astragalus root, the suberect spatholobus stem and the largehead atractylodes rhizome in the marrow-producing prescription can promote the bone marrow hyperplasia and have the positive promoting function of improving the hematopoiesis. Studies have found that the radix astragali injection prepared from radix astragali can increase the number of leukocytes, neutrophils, lymphocytes and monocytes of mice of the model of leukopenia. Caulis Spatholobi has the effect of improving hemopoiesis function, and can activate hemopoiesis system via multiple ways. The caulis Spatholobi can promote bone marrow granulocyte division, increase mouse leukocyte and bone marrow nucleated cell number, and has obvious stimulation effect on proliferation of myelomonocytic progenitor cells of anemic mice. Researches find that the bighead atractylodes rhizome has obvious positive promoting function on the leucocyte and function of an immunosuppressed mouse induced by cyclophosphamide and can also obviously improve the lymphocyte function of a normal mouse. Specifically, quercetin contained in fructus Lycii, radix astragali, fructus Ligustri Lucidi and semen Cuscutae can increase proliferation activity of mesenchymal stem cells, and promote osteogenic differentiation of mesenchymal stem cells, and the mesenchymal stem cells not only have mechanical support effect on hematopoietic stem cells in bone marrow, but also can secrete various growth factors (such as IL-6, IL-11, LIF, M-CSF and SCF) to support hematopoiesis. The quercetin can obviously improve the peripheral blood leukocyte count of mice with hypoimmunity caused by cyclophosphamide, can promote the proliferation of immune cells, regulate the immunosuppression and improve the immunity of organisms, the catechin contained in the caulis spatholobi, the quercetin neutralized by the medlar, the astragalus, the glossy privet fruit and the dodder, the kaempferol contained in the astragalus, the glossy privet fruit, the dodder and the epimedium, the luteolin contained in the caulis spatholobi, the glossy privet fruit and the epimedium and the like can directly or indirectly act on IL-6, IL-2, IL-10 and EGFR, the hematopoietic function in the organisms is activated, and the leukocyte count is increased. Luteolin has protective effect on natural aging of human red blood cell, and can prolong life of red blood cell. Catechin can regulate expression of hemopoietic genes such as HBE, HBG, HBA, HBB and HBD, erythropoietin receptor EPOR and key transcription factors MYB and PU.1 influencing hematopoiesis, and promote proliferation and differentiation of hemopoietic and erythroid progenitor cells. The astragalus polysaccharide contained in the astragalus can improve the immunoglobulin, immune cell subgroup and leukocyte level of a patient with postoperative adjuvant chemotherapy (oxaliplatin + tegafur SOX) for the gastric cancer, improve the immune state and promote later-period rehabilitation. Icaritin contained in epimedium has the effect of promoting thrombopoiesis on an ITP mouse by regulating T cell polarization. From the aspect of the passage: the PI3K-Akt pathway is a transduction pathway of signals of corresponding extracellular survival and growth of cells, and is a signal transduction pathway involved in regulation of cell growth, proliferation and differentiation. The PI3K-Akt pathway is closely related to blood diseases. The astragalus polysaccharide can promote the proliferation and differentiation of bone marrow stem cells, up-regulate the expression of PI3K and AKT mRNA, improve the protein content of pPI3K and p-AKT, and prompt that the astragalus polysaccharide activates a PI3K/AKT signal transduction pathway, and the regulation and control effect of the astragalus polysaccharide on the bone marrow stem cells is probably closely related to the PI3K/AKT signal transduction pathway. The tumor suppressor lipoid phosphatase PTEN can convert a messenger PIP3 generated by activating PI3K into PIP2 by dephosphorylation, so that the activity of the PIP2 is lost, Akt phosphorylation is blocked, a negative regulation effect is realized on a PI3K/Akt signal channel, and the expression of PTEN mRNA can be down-regulated after astragalus polysaccharide is used for preventing diseases, so that the inhibition of the activation of a PI3K/AKT signal transduction channel is reduced, and the proliferation of bone marrow stem cells is promoted. Catechin can activate JAK-STAT signal channel related to hematopoietic factor, promote hematopoiesis, and improve hematopoietic microenvironment. The formula disclosed by the invention can realize excellent synergistic effect on improving bone marrow suppression after chemotherapy through reasonable compounding.

The preparation method was the same as in example 1 except that the kinds of the drugs were added.

First, the effect of the composition of the invention on bone marrow suppression after chemotherapy of mice

The test method comprises the following steps: BALB/c mice were selected and randomly divided into 5 groups of 10 mice each, one of which was blank group, one was model group, and the remaining groups were example groups, and the mice were inoculated with mouse gastric cancer cells (MFC, density 1X 10, etc.) except for blank group⁷mL^-1) 0.2mL for each, when the volume of the underarm tumor is more than or equal to 200mm³And when no ulceration exists, the gastric cancer tumor-bearing mouse is successfully modeled, 100mg/kg of Cyclophosphamide (CTX) is injected into the abdominal cavity of the mouse, the injection is carried out once a day for three consecutive days, and a bone marrow suppression model after the chemotherapy of the mouse is established. On the next day after the molding is successful, the drug in each example group is intragastrically administered by 0.2mL (the particles are dissolved and are configured into a solution of 3 g/mL), and the blank group and the model group are administered with the same amount of normal saline once a day for seven consecutive days; after the last dose, mice were bled from their eyeballs, mixed with sodium citrate at a ratio of 9:1, and the white blood cell count (WBC), red blood cell count (RBC), total hemoglobin (Hb), and platelet count (PLT) were measured and the results were summarized in table 2.

Table 2 influence of groups on the conventional index of mouse blood

(Note: Δ: P < 0.05; Δ: P < 0.01; P < 0.05; P < 0.01; see: blank).

As can be seen from the above table, WBC, RBC, Hb, and PLT of the mice in the model group are significantly reduced compared to the blank group, and WBC, RBC, Hb, and PLT of the mice in the example 1 group are significantly improved compared to the model group. When using hispid fig to replace astragalus, or additionally adding morinda officinalis and prepared rehmannia root, as shown in comparative example 1 and comparative example 2, WBC pole was significantly increased, RBC and PLT were significantly increased, and Hb was not significantly increased in the comparative example 1 group compared to the model group; compared with the model group, the WBC of the mice is greatly improved, the PLT is obviously improved, and the RBC and Hb are not obviously improved in the comparative example 2 group, so that the composition can effectively improve the bone marrow suppression condition of the mice after chemotherapy.

Second, demonstration of the effectiveness of the compositions of the present invention in ameliorating chemotherapy-related myelosuppression

Note:

1. the laboratory examination results of each patient in the study design are divided into two stages, namely a first stage with the chemotherapy starting date as the starting point, two cycles (42 days) of chemotherapy ending as the end point, a second stage with the chemotherapy starting date of the third cycle as the starting point, four cycles (42 days) of chemotherapy ending as the end point, and the blood routine results of each stage of each patient are plotted on a line graph, and each line graph is plotted on a trend line.

2. Description of the basic case: a total of 11 cases were enrolled, 3 males and 6 females, with an average age of 57 years, with each case having the same number of first-stage and second-stage blood norms, 86 first-stage and 86 second-stage blood norms.

Each patient makes a line graph of each related index in the first-stage blood routine and the second-stage blood routine, then makes a trend line of the line graph, and records the slope of each trend line. When the same index slope in the first and second stages is the same, the smaller the value is, the more stable the data change in the stage is; when the slope is positive and negative, the rising of the data is represented by the positive slope, the falling of the data is represented by the negative slope, and the more stable the entry is brought into the stage with the positive slope; the slope is negative, and it is considered that the more negative the value is, the more stable the data is, and the more stable the data is included in the phase.

The research refers to the index Standard of the acute and subacute toxic response of anticancer drugs in the world health organization for grading the conventional myelocyte count, the leukocyte count, the hemoglobin, the platelet count and other indexes of the blood after chemotherapy, and counts the occurrence of the bone marrow suppression of all levels in the first and second stages.

TABLE 3 graduation Standard of acute and subacute toxicity reactions of anti-cancer drugs by the world health organization

Experimental results of preliminary study

(1) The first stage and the second stage data trend line slope statistics result:

TABLE 4 two-phase data trend line slope statistics

TABLE 5 two-phase data trend line slope stability statistics

(2) Comparison of bone marrow suppression in the first stage and second stage

TABLE 6 comparison of the first and second stage leucocyte inhibition

TABLE 7 comparison of first and second stages of neutrophil inhibition

TABLE 8 comparison of platelet inhibition in the first and second stages

TABLE 9 comparison of hemoglobin inhibition in the first and second stages

Analysis of clinical observations:

as can be seen from table 5, the slope stability of the second-stage white blood cell count, neutrophil count, red blood cell count, platelet count, and hemoglobin trend lines were all higher than that of the first-stage.

As can be seen from tables 6-8, white blood cell counts were observed at the second stage of clinical observation with 0-fold level III myelosuppression and 0-fold level IV myelosuppression, while 10-fold level III myelosuppression and 7-fold level IV myelosuppression occurred at the first stage. Neutrophil counts in the second phase of clinical observation, 1 in III degree myelosuppression and 0 in IV degree, while 7 in the first phase and 8 in IV degree myelosuppression. Platelet counts in the second phase of clinical observation, 3 and 0 degrees of III and 3 and 8 and 3 degrees of IV myelosuppression occurred in the first phase. Hemoglobin in the second phase of clinical observation, level III myelosuppression occurred 4 times, level IV myelosuppression 1 time, while level III myelosuppression in the first phase occurred 9 times, level IV myelosuppression occurred 5 times.

The preliminary results of this clinical observation show: for myelosuppression after chemotherapy, the change of myelosuppression is gradually stabilized along with the prolonging of the time of the oral myelogenesis formula, and the chance of developing the myelosuppression of III and IV degrees is reduced, so that the myelogenesis formula can stably promote and maintain the bone marrow hematopoiesis.
