Description

Hyaluronic acid-based thixotropic hydrogel for lubricating joint prosthesis and preparation method thereof
Technical Field
The invention relates to the technical field of bionic lubricating liquid, in particular to hyaluronic acid-based thixotropic hydrogel for lubricating joint prosthesis and a preparation method thereof.
Background
With age, the incidence of arthritis is increasing, but current data indicate that arthritis is moving towards younger age. When Osteoarthritis (OA), rheumatoid Arthritis (RA) or other infectious joint diseases occur, the composition of the joint lubricating fluid can be changed or the lubricating fluid can be reduced, the degree of friction of the joint is increased under the condition, a large amount of abrasion of the joint can be caused, so that the joint is diseased, the joint is painful, stiff and swollen, and the normal work of the joint is affected. Exogenous lubricating liquid can be injected into the early stage of pathological changes, which is beneficial to improving the friction condition of joints and inhibiting the pathological changes of the joints. Joint replacement operation is needed in the later stage of pathological changes, however, most of materials used for joint replacement are metal, ceramic, ultra-high molecular weight polyethylene and the like, friction and abrasion are inevitably generated due to the lack of a lubricating system of a normal joint, and abraded particles are a main reason for loosening of a joint prosthesis. In order to prolong the service life of the joint prosthesis, the bionic joint lubricating fluid is required to provide a lubricating effect, but the implantation of the joint prosthesis causes the joint capsule to be removed, the liquid bionic lubricating fluid cannot be stored, and the liquid lubricating fluid is not easy to adhere to the joint surface; further, the liquid bionic lubricating fluid is easy to pass, and in addition, the liquid bionic lubricating fluid has the problem of easy degradation (D.diamocoglu, K.Alptekin, B.Teksoz, et al.knee v.hip single-joint in-tissue with bone tip and knee osteo-arthritis: a pilot test, clin Rheumatol,2009,28, 1021-1024).
In view of the above problems, in order to increase the service life of the biomimetic lubricating fluid, it is required that the biomimetic lubricating fluid has excellent degradation resistance and easy storage property. Hyaluronic acid (also known as hyaluronic acid, abbreviated as HA) is a relatively common joint bionic lubricating fluid due to its good biocompatibility, but when hyaluronic acid is injected into a joint in vitro, the half-life of hyaluronic acid in the joint is about 12H under the degradation effect of in vivo enzymes, which greatly limits the lubrication time of HA in the joint (Kim H, jeong H, han S, et al, hyaluronic acid and its derivatives for stored biological applications [ J ] Biomaterials,2017, 123. In order to relieve the liquid lubricant from being easily degraded, the hydrogel is a good choice, and the hyaluronic acid crosslinked hydrogel is prepared by a chemical crosslinking method at present, but the crosslinked hydrogel prepared at present can only be lubricated under the condition of small stress (Kpa grade), and the hydrogel breaks with the increase of loading stress (Bonyadi S Z, dunn A C. Brittle or Ductle Abrasive Wear of polyacrylic Hydrogels sources Load-Dependent Wear mechanics [ J ]. Tribology Letters,2020,68 (1):.), so that the lubricating effect of the hydrogel is limited under the condition of human joint Load (stress is about 18 Gpa). Therefore, the development of the bionic joint lubricating liquid which has degradation resistance and storability and can realize the lubricating effect under the condition of human joint load has important scientific significance.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a hyaluronic acid-based thixotropic hydrogel for lubricating joint prostheses and a preparation method thereof, so as to solve the technical problem that the lubricating effect of the existing hyaluronic acid crosslinked hydrogel under the condition of human joint load is limited.
The technical scheme adopted by the invention is as follows:

(2) Crosslinking to form crosslinked hyaluronic acid or crosslinked sodium hyaluronate: uniformly mixing a cross-linking agent with the hyaluronic acid or sodium hyaluronate solution prepared in the step (1) according to a ratio, cross-linking for 3 hours under the condition of a water bath at 35-45 ℃, and then adjusting the pH of the mixed solution to be neutral by using the hydrochloric acid solution prepared in the step (1) to terminate the reaction, thus obtaining a cross-linked hyaluronic acid/sodium hyaluronate solution;
(3) Preparation of hyaluronic acid based thixotropic hydrogel: and (3) uniformly mixing the cross-linked hyaluronic acid/sodium hyaluronate solution prepared in the step (2) with the protein solution prepared in the step (1) according to the proportion to form a gel solution, and reacting for 60min under the water bath condition of 45-55 ℃ to obtain the hyaluronic acid-based thixotropic hydrogel.
Preferably, the alkaline solution in step (1) is one or more of ammonia water, sodium hydroxide solution or potassium hydroxide solution.
Preferably, the molecular weight range of the hyaluronic acid or the sodium hyaluronate in the step (1) is 6X 10 5 ~1.5×10 6 Da。
Preferably, the protein in step (1) is one or more of gelatin, silk fibroin or collagen.
Preferably, the crosslinking agent in step (2) is one or more of divinyl sulfone, 1, 4-butanediol diglycidyl ether, or genipin.
In summary, compared with the prior art, the invention has the following advantages and beneficial effects:
1. the thixotropy of the thixotropic hydrogel based on hyaluronic acid prepared by the invention is mainly derived from a supermolecule system in the components, mainly comprises electrostatic interaction and hydrogen bonds formed among the components, the supermolecule system is damaged when being subjected to external force, so that the hydrogel is converted into a sol state, and when the external force is removed, the components can rapidly re-form the electrostatic interaction and the hydrogen bonds to be recovered into a gel state. By utilizing the characteristic, when the shearing stress generated by the normal movement of the joint prosthesis acts on the thixotropic hydrogel, the thixotropic hydrogel can generate gel-sol transformation, so that a lubricating film is formed, and excellent lubricating performance is provided; when the joint prosthesis stops moving, the thixotropic hydrogel is subjected to sol-gel conversion, so that the thixotropic hydrogel is easily adhered to the surface of the joint prosthesis, the aim of protecting the joint capsule from lubricating liquid is indirectly fulfilled, the loss speed of the lubricating liquid is reduced, and the injection times are further reduced;
2. the raw materials of the invention are derived from proteins and hyaluronic acid/sodium hyaluronate in animal bodies in the nature, and have excellent biocompatibility, wherein the cross-linked hyaluronic acid has good viscoelasticity and long degradation time, and has the functions of protecting and inducing repair of articular cartilage of osteoarthritis, so the cross-linked hyaluronic acid is expected to be used for repairing the articular cartilage of a human body;
