Abstract： Background Knee osteoarthritis is a common clinical condition with a decades-long course. Long term and personalised health management in community hospitals is the best way to prevent and treat KOA，and non-surgical treatment is an effective way to slow joint degeneration and postpone joint replacement surgery. Objective To understand the population characteristics，clinical staging and treatment modality characteristics of the population attending community hospitals for knee osteoarthritis，in order to provide a basis for optimising the treatment protocol for knee osteoarthritis at the grassroots level. Method All streets in the urban area of Beijing were randomly selected for the study using the whole cluster sampling method，and Hepingli Street in Dongcheng District，Beijing was censored for all patients who attended all community hospitals（7） belonging to the street in January-June 2022，and general information，medical history，personal history，clinical staging，K-L grading and treatment modalities were collected. Results A total of 3 615 KOA patients were included in this study，including 1 327 males（36.71%） and 2 288 females（63.29%），aged（71.8±13.3） years. There were 867 cases（23.98%） in the onset period，209 cases（55.57%） in the remission period and 739 cases（20.45%） in the rehabilitation period. Gender and age of patients with different clinical stages were not correlated with clinical stages （P>0.05），while BMI（K=0.235） and KL grading（K=0.406） were correlated with clinical stages（P<0.001）. During the attack period，4~5 kinds of treatment methods（48.67%） were combined，and the treatment methods were mainly traditional Chinese patent medicines and simple preparations for external use（68.97%），475 cases（54.79%） of traditional Chinese patent medicines and simple preparations for oral use，and 396 cases（45. 67%） of health education; in the remission stage，2-3 treatment methods were used in combination（48.58%），mainly including 1 084 cases（53.96%） of traditional Chinese patent medicines and simple preparations for external use，1047 cases（52.12%） of health education and 790 cases（39.32%） of cupping; in the rehabilitation stage，2-3 kinds of treatment methods were used in combination（47.23%）. The main treatment methods were health education in 488 cases（66.04%），traditional exercises in 286 cases（38.70%），and external use of traditional Chinese patent medicines and simple preparations in 279 cases（37.75%）. There was a correlation between clinical stage and type of combination therapy（K=0.356，P<0.05）. Conclusion Patients in community hospitals are mainly in remission，and treatment is often combined with various methods of traditional Chinese patent medicine and simple preparations，and traditional exercises are also widely used.

Abstract： The existing algorithms can't enhance the details of image edges and effectively control the enhancement degree of each scale information. Aiming at the problem, this paper proposed a multi-level decomposition Retinex low-light image enhancement algorithm. On the basis of Retinex decomposition model and bilateral filtering, the algorithm can obtain the multi-level reflection components and illumination component by setting different filtering parameters. Using the exponential function to enhance the multi-level reflection components, the algorithm can effectively enhance the expression ability of the image edge details. And using the S-type function to process the final luminance component, the algorithm can improve the overall brightness of the low-light image while suppressing the high-luminance area. By processing the color restoration function as post-processing, the algorithm can further avoid the problems of color deviation and distortion. The experimental results show that the proposed algorithm can improve the visual quality of low light images and is superior to the existing algorithms in terms of clarity, information entropy, and contrast.
