Bionic coatings with excellent properties such as wear resistance and corrosion resistance can be used in harsh environments such as marine， petroleum， and chemical industries.Hence， it is of great significance for the preparation of advanced bionic coatings to study the bionic structure of natural biological materials， preparation methods and quality control methods of bionic coatings.In this work， the research statuses of bionic coatings prepared by high-energy beam cladding technology were introduced from two aspects: the preparation of bionic coatings and the quality control of bionic coatings by high-energy beam cladding technology.In terms of preparing bionic coatings by high-energy beam cladding technology， according to the classification of different bionic mechanisms， the strengthening mechanism of bionic coatings and the research status of coatings using high-energy beam preparation methods were reviewed.In terms of quality control of bionic coatings， the role of process optimization and numerical simulation in the preparation process in regulating the performance of bionic coatings prepared by high-energy beam cladding technology was explained.Finally， the shortcomings in the current research were summarized， which could provide reference directions and prospects for subsequent researches.

Objective: To compare the response of simple endoscopic surgery and endoscopic surgery plus small windows through canine fossa surgery for fungal maxillary sinusitis., Method: Twenty-five patients were applied the endoscopic surgery plus small windows through Canine fossa surgery as the treatment group, and the other 25 were applied the simple endoscopic surgery as control., Result: During a follow up for 1-2 years, the effect of fungal maxillary sinusitis under endoscopic by dual approach is superior to simple endoscopic. There were obvious differences between the two groups(chi2 = 4.268, P < 0.05)., Conclusion: Endoscopic surgery plus small windows through canine fossa surgery for fungal maxillary sinusitis can fully expose maxillary sinus cavity,destroy the abnormal tissues completely, change the low oxygen environment, ensure the normal physiological function of maxillary sinus mucosa, and really achieve radical minimally invasive purpose.
