The invention is further described below with reference to the accompanying drawings.
Example 1: a method for evaluating the developmental toxicity of high-concentration glucose by using zebra fish comprises the following specific operation steps:
s1, preparing glucose solutions with mass concentrations of 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3% and 3.5% respectively by using the embryo culture solution;
s2: mating and laying eggs by using at least 3 pairs of male and female wild zebra fishes (AB type), collecting and selecting fertilized eggs and uniformly mixing the fertilized eggs together;
s3: respectively putting the prepared glucose solution with 7 concentrations and the embryo culture solution into 6-hole plates, adding 10ml into each hole, putting 30 fertilized eggs into each hole, repeating the steps in parallel by taking each three holes as a group, and culturing under normal conditions; the fertilized eggs put into the embryo culture solution are used as a control group, and the fertilized eggs put into the glucose solution are used as an experimental group; the normal culture conditions were: controlling the temperature at 28.5 ℃; the photoperiod is: light/dark 14/10 hours.
S4: replacing the culture solution every 12 hours in the culture process, continuously replacing the glucose solution in the experimental group, and continuously replacing the embryo culture solution in the control group; feeding the zebra fish juvenile fish feed when the culture solution is changed every day from the fifth day, observing the growth form of the zebra fish, and counting the spinal deformity rate and the death rate of the zebra fish juvenile fish; statistics of spine deformity and mortality of zebra fish juvenile fish on day eight are shown in fig. 2. Referring to fig. 1, the spine distortion rate and death rate of zebra fish juvenile fish are remarkably increased with the increase of the sugar concentration of the glucose solution.
S5: staining the zebra fish juvenile fish with the curved spine by using an active oxygen fluorescent probe, washing the stained zebra fish juvenile fish with a PBS buffer solution, and observing the staining condition on a glass slide under a fluorescent microscope (see the attached figure 3); staining zebrafish juvenile fish with curved spine with acridine orange staining solution, and then staining with ddH2And O, washing the juvenile fish clean, and observing the juvenile fish staining condition under a fluorescence microscope (see attached figure 4).
The specific steps of staining with the active oxygen fluorescent probe in step S5 are as follows: the zebra fish with the curved spine is firstly stained for 30min at 37 ℃ by using a 10 mu M/L active oxygen fluorescent probe, and the stained zebra fish juvenile fish is washed clean by using PBS buffer solution.
The step S5 of dyeing with the acridine orange staining solution comprises the following specific steps: zebrafish larvae with a curved spine were stained with acridine orange staining solution at a concentration of 400. mu.g/L at 25 ℃ for 30min and rinsed clean with ddH 2O.
The treatment group (i.e., experimental group) of fig. 3 is a fluorescent photograph of zebrafish juvenile fish after being stained with the ROS fluorescent probe, which was continuously exposed to a 3% glucose solution for 6 days; the normal group is a fluorescence picture of the zebra fish juvenile fish dyed by the ROS fluorescent probe under the normal growth condition. As can be seen from the fluorescence photographs of the control group and the treated group in FIG. 3, the fluorescence intensity in the photograph of the treated group is significantly stronger than that of the control group, and the stronger the fluorescence intensity, the stronger the brightness, the more ROS are accumulated.
The treatment group (i.e., experimental group) of fig. 4 is a fluorescent photograph of zebrafish larvae after acridine orange staining, which were continuously exposed to a 3% glucose solution for 6 days; the normal group is a fluorescent picture of zebra fish juvenile fish stained with acridine orange under normal growth conditions. The acridine orange can stain early apoptotic cells, the stronger the brightness is, the more serious the apoptosis is, and the stronger the developmental toxicity of high sugar is, and it can be obviously seen from fig. 4 that the area with brightness and the intensity of the zebra fish juvenile fish cultured by the high-concentration glucose solution are both obviously higher than those of the control group, which indicates that the apoptosis degree of the zebra fish juvenile fish cultured by the high-concentration glucose is obviously far higher than that of the control group.
The invention utilizes zebra fish to evaluate the developmental toxicity of high-concentration glucose, in the evaluation process, the spinal deformity of the zebra fish juvenile fish cultured by the high-concentration culture solution is obvious in characteristic, and the spinal deformity is higher along with the higher concentration of the glucose, which shows that the correlation of the glucose concentration on the developmental influence of the zebra fish spinal is very large, the genome sequence of the zebra fish is highly similar to the human genome, and a plurality of important tissue organs including a cardiovascular system and a nervous system are similar to human in morphological structure, physiological function and pathological reaction, so the evaluation result of the invention and the glucose concentration have great reference significance on the developmental toxicity of the human.
The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
