Statistically significant differences were tested for group differences (post hoc Dunn's test) according to one-way ANOVA analysis of IBM SPSS Statistics software, P <0.05 considered the group differences significant, with statistical significance.
(3) Experimental results
Morris water maze test results: the experimental results of the platform time of each group of mice, namely escape latency are shown in Table 2, example 1 is mixed powder of four bacteria of Hericium coralloides, armillariella mellea, boletus and Morchella, the platform time of the mice can be obviously shortened after 3 weeks of administration (P < 0.05), and the experimental results are superior to those of the single component administration, namely comparative examples 2-4 (P > 0.05), and the effect of the single component administration is similar to that of the coralloid Hericium coralloides powder of comparative example 1. The four bacterial powders in examples 2-5 are mixed in a certain proportion and then subjected to hot water leaching, so that the obtained healthcare product composition with the neuroprotection and memory improvement can remarkably shorten the time for searching the platform of the mice (P < 0.05), the time for searching the platform of the mice can be remarkably shortened in examples 3 and 5, and the spatial memory of the mice is improved, wherein the effect of example 5 is most obvious, and compared with mice in a blank control group, the time is shortened by 39.6% (P < 0.01). This demonstrates a significant improvement in cognitive and memory in mice following administration of the compositions of examples 1-5. In addition, as a result of comparing the examples with the comparative examples in the lateral direction, the effect of reducing the mouse seeking time due to the synergistic effect of the examples is more obvious, significance (P <0.05 and P < 0.01) is universally present, and the effect of the comparative examples is mostly insignificant (P > 0.05).

Central cholinergic related index determination results: acetylcholine (Ach) associated with learning memory and cognitive abilities is an important neurotransmitter in the brain reflecting the status of cholinergic neurons. Neurotransmitter Ach acts on many cholinergic receptors and is also an excitatory neurotransmitter of many motor nerves, and an increase in its content is associated with an improvement in alzheimer's disease. Both AchE as Ach hydrolase and ChAT as Ach synthase can be used to regulate Ach metabolism.
As shown in table 3, the results of experiments show that, after the mice were subjected to gastric administration for 3 weeks, the single fungus powder of comparative examples 1 to 4 was administered only to coralloid Hericium erinaceus to significantly reduce the level of AchE (P < 0.05), the levels of AchE in the hippocampus of the mice were not significantly changed by armillaria mellea, boletus and Morchella (P > 0.05), and the levels of AchE were significantly reduced in examples 2 to 5 obtained by hot water extraction of the four fungus mixtures mixed in a certain ratio. Examples 1-5 significantly increased the Ach content in the hippocampus of mice (P < 0.05) compared to the placebo group, with example 5 being optimally effective at 1.23 times the placebo group, whereas the administration of a single powder intragastric gavage in the comparative example did not significantly change the Ach content in the hippocampus of mice (P > 0.05). For ChAT, example 5 significantly increased ChAT levels in the hippocampus of mice (P < 0.05) compared to the placebo group, while examples 1-4 all significantly increased ChAT levels (P < 0.01), with example 3 being most effective. The experimental results of comparative examples 1 and 3 show that the single powder administration of armillaria mellea and morchella also significantly increases the ChAT level (P < 0.05) in the hippocampus of mice, but the effect is not significant in the examples. By combining AChE, ach and ChAT experimental results, it can be seen that the health care product composition with neuroprotection and memory improvement can achieve neuroprotection by improving the level of central cholinergic related indexes, wherein the level of Ach and ChAT can be obviously changed in example 1 prepared by mixing four bacterial powders in a certain proportion. The health-care product composition with the nerve protection and memory improvement obtained after hot water extraction shows better effect. The comparative examples have the same effects, but the effects of the individual effects are not obvious and are not remarkable because the action routes of the different bacteria are different.

oxidative stress related index measurement results: oxidative stress is the basis of pathophysiological important assumptions for many diseases, including neurodegenerative diseases. The SOD serving as natural enemy of oxygen free radicals is scavenger of organisms, can remove harmful substances generated in the organisms, has an anti-aging effect, can prevent the generation of the oxygen free radicals, and can prevent the generation of the oxygen free radicals from damaging cells, thereby repairing the damaged cells. The experimental results are shown in table 4, and compared with the blank control group, the SOD content in the serum of the mice can be obviously improved (P < 0.05) in the example 2, and meanwhile, the SOD content in the serum of the mice can be obviously improved (P < 0.01) in the examples 3, 4 and 5. In addition, the SOD content in the serum of the mice is also improved in example 1 and comparative example, but the effect is not significant. In addition, examples 2, 4 and 5 and comparative example 3 can significantly scavenge ROS in mouse serum, on the basis of which the scavenging effect of examples 2 and 3 on ROS is extremely pronounced (p < 0.01), wherein the ROS level of example 2 is reduced by 33.6% (p < 0.01) compared to the blank. In conclusion, the health care product composition with the function of neuroprotection and memory improvement can improve the oxidative stress state of mice. Compared with the single-component bacterial powder of comparative examples 1-4, the four bacterial powders compounded in a certain proportion show better antioxidation effect after hot water leaching.

in vitro cell experiments show that the health-care product composition with neuroprotection and memory improvement obtained after hot water leaching has better neuroprotection effect than single fungus powder, and the same experimental result is verified in animal experiments. The experimental results show that each example shows good memory and cognition improving ability and has obvious antioxidation and anti-aging effects by comparing with the blank control group and the comparative example, namely the single-component bacterial powder. Example 1 is an untreated mixed bacterial powder, which shows a certain memory improving effect, but examples 2-5 obtained after hot water leaching show more excellent effect, and in conclusion, the composition of the invention can be used as a health care product composition for improving cognition and memory.
