Problems solved by technology

However, when the nano-hydroxyapatite particles are used, they need to be placed around the tumor cells and corresponding tissues, and a large amount of interstitial fluid produced after the operation will flush the fine hydroxyapatite particles out of the body along the drainage tube, to a great extent. The effect of its anti-tumor effect
In addition, although surgery

Example Embodiment

[0028] Example 1 A nano-hydroxyapatite composite material with tumor-inhibiting effect

[0029] The preparation method includes the following steps:

[0030] I. Take 300ml of purified water, add 15g of starch, and stir while adding. After the solution is uniform, measure the volume of the solution, and then add 1g of sodium hydroxide. After cooling, measure the volume of the solution. Use purified water to supplement the evaporated liquid volume. Evenly, get mixed solution A;

[0031] II. Take 45g of nano-hydroxyapatite and add it to the mixed solution A obtained in step I, stir evenly, weigh, and react for 40 minutes while stirring in a water bath at 90°C until the starch is completely gelatinized, take it cold and weigh it, and supplement with purified water Weight, mix well, get mixture B;

[0032] III. Add 3 g of sodium trimetaphosphate to the mixture B obtained in step II, stir at room temperature for 10 minutes, and then heat and stir at 90°C for 15 minutes to obtain a gel, whi...

Example Embodiment

[0033] Example 2 A nano-hydroxyapatite composite material with tumor-inhibiting effect

[0034] The difference from Example 1 is that the weight ratio of starch to nano-hydroxyapatite in Example 2 is 1:1, and other parameters and operations refer to Example 1.

Example Embodiment

[0035] Example 3 A nano-hydroxyapatite composite material with tumor-inhibiting effect

[0036] The difference from Example 1 is that the weight ratio of starch to nano-hydroxyapatite in Example 3 is 1:6, and other parameters and operations refer to Example 1.

Abstract

The invention belongs to the field of biomedical materials, in particular to a nano-hydroxyapatite composite material with tumor inhibiting effect and a preparation method thereof. The composite material is made of nano-hydroxyapatite and starch, and the weight ratio of the starch to nano-hydroxyapatite is 1: (0.5-6). The nano-hydroxyapatite and the gelatinized cross-linked starch are combined byhydrogen bonding, Hydroxyapatite can be uniformly distributed in the starch gel crosslinking system, which has good biocompatibility and high safety. It can inhibit tumor and promote tissue repair, and can effectively act on tumor site and significantly reduce the recurrence and metastasis rate after tumor resection.

Description

technical field [0001] The invention belongs to the field of biomedical materials, and in particular relates to a nano-hydroxyapatite composite material capable of inhibiting tumors and a preparation method thereof. Background technique [0002] Tumor refers to the new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors. At present, chemotherapy is one of the three major means of treating tumors. The antitumor drugs used mostly act on different links of tumor cell growth and reproduction, inhibit or kill tumor cells, but at the same time cause damage to normal somatic cells of the human body. . Chinese patent application CN104288784A discloses a nano-hydroxyapatite-gene-drug complex and its preparation method and application. The complex is composed of nano-hydroxyapatite, anti-tumor genes, and anti-tumor drugs. The salt solution is mixed to prepare nano-hydroxyapatite, the anti-tumor gene is adsorbed to form a nano-hy...
