Echinococcosis (Hydatid disease), also known as Echinococcosis, is a parasitic infection of people and livestock caused by the fact that larvae of Echinococcosis are parasitic to human bodies, and is an important public safety problem worldwide. The disease is common in North China, north America, europe, russia and the like. Among them, china mainly prevails in regions such as five northwest provinces, inner Mongolia, tibet and Sichuan, and Xinjiang is a high-frequency region. Echinococcosis seriously endangers human health and hinders the development of animal husbandry, so how to inhibit the echinococcosis and ensure the physical health of people and promote the economic development of animal husbandry has become an important concern in the current society.
The preferred treatment for cystic and follicular echinococcosis is surgical treatment. But medication is the best approach for patients who cannot tolerate surgery or who have lost the opportunity for surgery. The clinical first-line drug for treating echinococcosis is benzimidazole drug. The main components include albendazole and mebendazole. Albendazole is known worldwide to be the best therapeutic drug for treating echinococcosis, and the dosage form of albendazole is an oral tablet. However, the benzimidazole medicine has the problems of single preparation, poor bioavailability, low liver distribution, frequent administration and the like, so that the clinical treatment effect of the echinococcosis is poor. Because the artemia are usually parasitic to the liver, the burden of the liver is increased, the detoxification is reduced, and the toxic and side effects of the medicine are greatly increased by high-dose and frequent administration. Therefore, the bioavailability of benzimidazole drugs is improved, the ability of the drugs to permeate the wall of the bag worm is enhanced, and the increase of the effective concentration in the bag is the primary problem for treating the echinococcosis.

When the composition of the photodynamic combined medicine is used, the combined photodynamic therapy and the echinococcosis-resistant chemical medicine can be adopted, so that the effect of killing the echinococcosis efficiently is achieved.
Photodynamic therapy (Photodynamic therapy, PDT) is a new method for treating diseases with photosensitizers and lasers. The target is irradiated with a specific wavelength to activate the photosensitizing drug accumulated in the target tissue, which initiates a photochemical reaction to destroy the target. Photosensitizers in photodynamic therapy transfer energy to surrounding oxygen to generate active oxygen with killing properties, which reacts with nearby biological macromolecules to produce cytotoxicity which in turn kills the target tissue. Photodynamic therapy has the advantage of enabling accurate and effective treatment with minimal side effects compared to conventional therapies.
Aiming at the problem that the medicine is difficult to enter the bag wall of the bag to reduce the curative effect in the echinococcosis treatment, the invention can realize the combination of the photodynamic and chemical medicines, provides the composition of the photodynamic and chemical medicines for the echinococcosis treatment, can strengthen the capability of the anti-echinococcosis medicine to penetrate through the bag wall of the bag, increase the effective medicine concentration in the bag, damage the bag wall of the bag by using the photodynamic treatment, and increase the accumulation of the chemical medicines in the bag wall of the bag, thereby improving the echinococcosis treatment effect.

Example 11: a PBS solution of 1 mg/mL chlorin e6 (Ce 6) was prepared. 10 mg of Ce6 solid powder is weighed into a penicillin bottle, 5 mL of PBS solution is added, naOH solution (1M) is dropwise added under magnetic stirring until the Ce6 solid is completely dissolved, then HCl solution (1M) is used for adjusting the pH value of the solution to 7.4, the solution is transferred into a 10 mL volumetric flask, the medicament on the wall of the penicillin bottle is washed by PBS, the washing liquid is transferred into the volumetric flask, and the PBS solution is supplemented to the scale mark of the volumetric flask.
The cercaria were cultured in 24-well plates at a concentration of 2000 per well, and 20. Mu.g/mL Ce6 broth was added per well. After co-treatment of the larvae with Ce6 broth for 2, 4, 8 and 24, h, the broth was removed, the larvae were washed 3 times with PBS, 600 μl of 0.1M NaOH solution was added to each well, and transferred to a 2 mL centrifuge tube, and the larvae were ground 45 s using a grinder. The grinding fluid is centrifuged for 5 min by 10000 r/min, 200 mu L of supernatant is added into a 96-well plate, and the fluorescence intensity of 660 nm under 405 nm excitation light is measured by a multifunctional enzyme-labeled instrument, wherein the fluorescence intensity is the fluorescence intensity of Ce6 ingested by the metacercaria. Each group is provided with 3 parallel holes. As shown in FIG. 1, the results show that the metacercaria can be taken in a large amount of photosensitizers and has time dependence.
Example 12: the cercaria is cultured in 24-well plates at the concentration of 2000 heads per well, and after 2 h times of co-culture with 5, 10, 15 and 20 mug/mL Ce6 culture solution, the plates are washed three times with PBS, replaced with normal culture solution, and subjected to 30 min illumination with 635 nm visible light with the light dose of 5 mW/cm2, and then cultured for 24 h. 10 mu L of the metacercaria were stained with H & E3 times per well, and survival of the metacercaria in the well plate was counted. Three parallel wells were provided for each concentration. As shown in fig. 2, the photodynamic therapy has a certain killing effect on the metacercaria, but the effect is not remarkable as shown in fig. 2.
Example 13: the albendazole nanoparticles were prepared using a thin film dispersion method. 90 mg of PLGA-PEG,10 mg albendazole, was first added to a 50 mL round bottom flask and dissolved in 10 mL acetonitrile. Then, the organic solvent was removed by rotary evaporator at 40℃to form a transparent film. A PBS solution, preheated to 40 ℃ at 2 mL, was added to the flask and sonicated at 40 ℃ for 20 min to disperse the film to form nanoparticles. The resulting solution was centrifuged at 3500 r/min for 5 min to remove unencapsulated drug. The nanoparticles were demulsified using acetonitrile to calculate albendazole drug concentration.

Example 14: the 10. Mu.g/mL Ce6 treated 2H and then irradiated by light were cultured for 24H, and then H & E stained in the well plate, and observed and photographed using an optical microscope, as compared to untreated H & E stained larvae. As shown in FIG. 4, it is clear from FIG. 4 that photodynamic therapy can disrupt the wall integrity of the protocercaria, thereby increasing the drug concentration of albendazole within the protocercaria.
Example 15: the cercaria was cultured in 24-well plates at a concentration of 2000 wells per well, 1.5 h were co-cultured with the cercaria using 0, 5, 10, 15, 20. Mu.g/mL Ce6 broth, and then an active oxygen assay reagent DCFH-DA was added to give a concentration of 10. Mu.M per well. Culturing for 30 min, removing culture solution containing Ce6 and DCFH-DA, washing the original cercaria with PBS three times, and using 5 mW/cm 2 The 635 nm dose of visible light was illuminated for 30 min. Finally, blue light excitation is carried out on the metacercaria in the pore plate by using an inverted fluorescence microscope, and the generation condition of active oxygen in the metacercaria is observed. The brighter the fluorescence indicates more active oxygen is produced. As shown in FIG. 5, the photodynamic therapy can destroy the wall of the metacercaria by generating active oxygen as shown in FIG. 5.
Example 16: the primordial vesicles were incubated in 24 well plates at a concentration of 200 per well, and the vesicles were treated using different methods: 1. no treatment is performed; 2.100 μg/mL free albendazole treatment; 3.100 Treatment of mug/mL albendazole nanoparticles; 4.15 Mu g/mL Ce6 treatment of 2 h followed by 5 mW/cm 2 635 and nm light dose, visible light irradiation for 30 min (hereinafter referred to as photodynamic therapy); 5. treatment with 100 μg/mL free albendazole after photodynamic therapy; 6. after photodynamic therapy, 100. Mu.g/mL albendazole nanoparticles were used. Vesicles were photographed and compared using an optical microscope after drug treatment 24 h. As shown in FIG. 6, it is clear from FIG. 6 that the combination of photodynamic therapy and anti-artemia agent can cause shrinkage of vesicles, and has ideal effect of killing artemiaIs effective in (1).
