ABSTRACT
@#AIM: To explore the risk factors of retinal artery stenosis and its relationship with urinary albumin/creatinine in patients with hypertension, so as to provide a basis for prevention of target organ damage. <p>METHODS: In this study, a cross-sectional study was conducted in 1 983 patients with hypertension. According to the fundus examination, 944 patients were divided into normal group and 1 039 patients were divided into abnormal group. Baseline data were collected and urine albumin/creatinine was measured. Analysis of risk factors for retinal artery stenosis and its relationship with urinary albumin/creatinine.<p>RESULTS: There were significant differences in age and diabetes between the two groups(<i>P</i><0.05). Logistic regression showed that age(<i>OR</i>=1.013, <i>P</i>=0.011)and diabetes mellitus(<i>OR</i>=1.352, <i>P</i>=0.008)were risk factors for retinal artery stenosis. Hypertensive retinopathy(HR)detection rate was 95.56%. Grade I and grade II mild lesions were the major ones. The proportion of macroalbuminuria in retinal stenosis group was 65.59%, higher than that in microalbuminuria group(54.21%)and normal group(50.52%). <p>CONCLUSION: Age and diabetes are risk factors for retinal artery stenosis in hypertensive patients. Retinopathy is associated with urinary albumin/creatinine. The community should strengthen health education and early screening of retina and kidney to prevent the progress of the disease.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the sanitary status of urban secondary water supply facilities in Haidian district of Beijing.</p><p><b>METHODS</b>Adopting the quantitative classification table drafted by the Bureau for Sanitation Inspection and Supervision of Haidian district, we carried quantitative classification (A, B, C grade) on all 1725 secondary water supply facilities in Haidian district for two times. At the same time, we collected 20 residential areas with stratified random sampling method. As the public points in the first quantitative classification, the effect of level publicity on changing the sanitary grade of the secondary water supply facilities were observed.</p><p><b>RESULTS</b>In the first two times of quantitative classification, A-level and B-level secondary water supply facilities took up 81.04% (1398/1725) and 89.04% (1536/1725) of all secondary water supply facilities respectively; the ratio of effective sanitary permits achieved 86.14% (1486/1725) and 92.35% (1593/1725) respectively; and the ratio of effective water quality test reports achieved 86.60% (1494/1725) and 97.10% (1675/1725) respectively. There were 52 secondary water supply facilities in 20 collected areas, including 8 A-level, 27 B-level and 17 C-level secondary water supply facilities before level publicity, and 19, 29 and 4 after level publicity. The impact of level publicity on changing the sanitary grade of the secondary water supply facilities was statistically significant (χ(2) = 12.60, P = 0.002).</p><p><b>CONCLUSION</b>The city secondary water supply facilities in Haidian district are overall in good sanitary conditions. Quantitative classification and level publicity can effectively improve the sanitary status of secondary water supply facilities.</p>

Plasma concentrations of immunoreactivc beta-endorphin in patients with NIDDM were measured by radioimmuno-assay. It was found that the plasma beta-endorphin levels decreased in 68 cases of NIDDM especially in those with long duration of illness and chronic complication. These results suggested that beta-endorphin may be related to diabetes and its chronic complication.
