The cyclodialysis cleft is a rare disease characterized by ocular hypotony and vision loss.Gonioscopy,ultrasound biomicroscopy and anterior segment optical coherence tomography are used to evaluate the cleft before treatment.The evaluation of cyclodialysis clefts provide a basis for the selection of treatment and the evaluation of effect.Current popular therapeutic approaches for cyclodialysis clefts include medical management,laser photocoagulation,transscleral diathermy,cryotherapy,cyclopexy and so on.Medical treatment is effective in small-size cyclodialysis cleft.But the indications and course of medical treatment remains controversial.Although laser photocoagulation,transscleral diathermy and cryotherapy are effective to treat cyclodialysis clefts in some cases,there are some risks,such as ocular damage,uncertainty about the effect and so on.Cyclopexy is the principal method for cyclodialysis clefts that failed to respond to conservative management,including extraocular cyclopexy,intraocular cyclopexy and cyclopexy under endoscopic.The modified cyclopexy is effective which reduces the surgical risk.For keeping the lens,intraocular cyclopexy and cyclopexy under endoscopic are not suitable.Vitrectomy combined with other method for cyclodialysis is effective for cyclodialysis clefts which combined with serious posterior segment damage.

Objective To evaluate the construction status of a healthy city in central China, and clarify the weak links and construction results in the construction of a healthy city, and to provide a basis for the relevant government departments to issue policies. Methods Healthy city construction evaluation system in this city was established according to the National Healthy City Construction Evaluation System (2018) of the National Healthy City Evaluation Office Forty-two sets of health city construction index data in 2017-2018 were collected and analyzed. The single index was calculated according to the Guidance Manual for Filling in the Healthy City Evaluation Data, and the single index data was then standardized. The Delphi method was used to consult the weights of the three-level index. Finally, the sub-index and the total index of each dimension of the city's healthy city construction were calculated based on the health index method. Results The results of the 2017-2018 healthy city construction evaluation showed that 35 of the 42 indexes participated in the evaluation, and the total-indices of the two years were 77.71 and 79.95, respectively. The two-year sub-indices of the five dimensions of health service, health culture, health environment, healthy population, and healthy society were 17.17 and 18.32, 11.39 and 12.85, 19.21 and 17.94, 13.81 and 13.81, 16.12 and 17.04, respectively. Except for the decline in the health environment dimension, the other four sub-indices and the total healthy city index showed an upward trend year by year. In the past two years, the comprehensive proportions of the corresponding weight of the five dimensions sub-indices were 95.58% in health culture, 95.47% in health service, 73.99% in health environment, 73.27% in healthy society, and 69.52% in healthy people. Conclusion After the construction of national healthy city and the pilot construction of national healthy city, a city in central China achieved its first results in five dimensions of healthy city. In 2018, among the 35 indexes participated in the evaluation in this city, 30 were positive, and 26 were better than the national/ provincial target value. However, some construction indices were still far from the standard values. The development of the five dimensions was unbalanced, and there were weak links in different degrees.

Objective To investigate the prevalence of common diseases among primary and secondary school students in Yichang City from 2019 to 2022, and to provide a scientific basis for formulating effective intervention measures in the future. Methods By random cluster sampling , 7 schools in urban areas and 5 schools in suburban counties were selected to screen common diseases such as myopia, dental caries, obesity and abnormal spinal curvature. Descriptive epidemiological methods were employed for statistical analysis. Results A total of 17 023 primary and secondary school students were screened from 2019 to 2022. The overall detection rate of common diseases from high to low was myopia (54.12%), caries (36.75%), overweight (15.17%), obesity (11.88%), malnutrition (5.80%), and abnormal spinal curvature (3.49%). The detection rates of myopia and abnormal curvature of the spine showed an increasing trend with years and school stages, while the detection rates of malnutrition and dental caries showed a decreasing trend with years and school stages. The detection rates of overweight and obesity showed no trend difference with years, and the detection rates of obesity showed a decreasing trend with school stages. The rates of myopia, overweight and obesity were higher in urban areas than those in suburban counties, and the rate of dental caries was higher in suburban counties than that in urban areas. The prevalence of overweight, obesity, and malnutrition in boys was higher than that in girls. The prevalence of myopia and dental caries in girls was higher than that in boys. The above differences were statistically significant (all P<0.05). Conclusion Myopia, dental caries, obesity, and abnormal curvature of the spine are the current focus of the prevention and treatment of common diseases in students. There are great differences between different regions, school stages, and genders. The ^“tripartite linkage^” of schools, families, and communities should be achieved with the joint efforts of the education and health departments to actively take targeted intervention measures to reduce the prevalence.
