OBJECTIVE: To evaluate 3 published questionnaires for screening diabetes for rural samples in China. METHODS: Three screening questionnaires (Finnish Diabetes Risk Score, Danish Diabetes Risk Score, and Chinese Diabetes Risk Score) were selected through literature review, and were employed in a rural community sample in Wangcheng, Changsha. RESULTS: Sensitivity of these risk scores was 63.72%, 56.64% and 82.30%; the specificity was 79.75%, 62.64% and 46.90%. The area under the receiver operating characteristic curve (AUC) was 0.78 (95% CI: 0.73-0.83), 0.65 (95% CI: 0.60-0.70) and 0.68 (95% CI: 0.63-0.73). CONCLUSION The 3 screening questionnaires show a lower validity than originally described when applied to rural samples in the study. Difference in population characteristics is a possible reason. F-DRS is better than the other two, suggesting that F-DRS is more suitable for diabetes screening in China rural areas.

Objective:To understand the reserves of wild resources and artificial cultivation of Curcuma aromatica Salisb. in Guangxi, so as to provide basis for the conservation, rational development and utilization of germplasm resources of Curcuma aromatica Salisb. in Guangxi. Methods:By using literature retrieval and field investigation methods to analyze of geographic distribution, growing environment and community of Curcuma aromatica Salisb. in Guangxi. Results:Wild Curcuma aromatica Salisb. has strong adaptability and is growing in limestone mountains, earthen hills and plains. It usually grows at the foot of mountains or the edge of gullies or on the farmland or along the roads. It has a strong adaptability to altitude, soil type. The habitat of wild Curcuma aromatica Salisb. has been destroyed by human reclamation. Conclusion:The geographical distribution, growing environment and community of wild resources of Curcuma aromatica Salisb. in Guangxi were known, which provids the reference for the conservation, development and utilization of Curcuma aromatica Salisb.
