Abstract: |
1990~2001年全市共上报麻疹3 138例,年平均发病率为4.93/10万.麻疹疫苗(麻苗)使用前麻疹发病呈自然流行状态,年均发病率达1 222.46/10万.麻苗使用后,随着计划免疫工作的不断进展,特别是实现计划免疫"三个85%"目标后,接种率和接种质量不断提高,麻疹发病率呈明显的阶段性下降,年平均发病率从1 222.6/10万下降到226.7/10万,直至上个世纪末进一步下降到4.93/10万. |

Objective The purpose of this study was to understand the awareness, prevalence of diabetic retinopathy and treatment status of people aged over 50 and living in the rural areas of Shuangcheng city, Heilongjiang province, China. Methods Cluster sampling was used in randomly selected 5504 survey for ophthalmic clinical examination, in patients with diabetic retinopathy. A questionnaire in the state of knowledge about prevention and treatment was developed. Results Among the 5504 persons entering in the project, 5053 were examined on their eyes (91.8%). In this selected population, 56 persons (112 eyes) were diagnosed as diabetic retinopathy (1.108%), with 95% confidence interval (CI) as: 0.819% to 1.397%. Of 56 patients, 49 cases were non proliferative diabetic retinopathy, accounting for 87.50% of the total number of patients with diabetic retinopathy;proliferative diabetic retinopathy 7 cases, accounting for 12.50% of the 112 eyes, 6.25% (7/112)having vitreous hemorrhage, 8.04% (9/112) having macular edema. For diabetic retinopathy prevalence rates, there was no significant difference in males and females. Between the per differential 10 year old division, the difference was significant. Among the 60 to 69 group, a significantly higher prevalence rate was seen. Of the 112 eyes with diabetic retinopathy, 34 eyes(30.4%) were low vision [visual acuity <20/60 (0.3) to ≥ 20/400 (0.05) ]; 6 eyes (5.4%) were blind [visual acuity <20/400 (0.05) to NLP]. The rate in the patients with PDR and fasting blood glucose was above 11.1 mmol/L was higher than having NPDR and fasting blood glucose below 11.1 mmol/L. Having fasting blood glucose 11.1 mmol/L and above with the course over five years among patients with PDR, the proportion of fasting blood glucose was higher than those with less than 11.1 mmol/L and diabetic retinopathy duration of less than five years. Of 56 patients with diabetic retinopathy, 38 cases (67.9%) did not receive any treatment. Among 18 cases (32.1%) with insulin or oral drug therapy,regularly using insulin or other medication (14.3%), only 1 (1.8%) case was given the treatment for diabetic retinopathy. Results from our survey showed that patients with diabetic retinopathy had a poor understanding about prevention and treatment of the disease. Conclusion Long duration and high blood glucose in patients with diabetic retinopathy seemed to be the important risk factor. Early systematic drug use for prevention and blood glucose control was the key to prevent diabetic retinopathy. Patients with diabetic retinopathy in China had poor understanding about the prevention measures of the disease and lack of knowledge. |
