Objective: To determine the distribution characteristics of waist circumference (WC), waist height ratio (WHtR) of 6–18 years olds in Guangzhou, and to put forward the WC and WHtR appropriate boundary values for 6–18 years olds on the basis of cardiovascular disease (CVD) risk factor assessment. Methods: We analyzed the height, weight, WC and its metabolic indication data (blood pressure, fasting blood glucose, and blood lipids) of 15 000 children in Guangzhou, aged 6–18, with the receiver-operating characteristic curve (ROC), and explored the best value point of WC and WHtRfor the prediction of cardiovascular diseases. Results: When the WC percent reached P85, and WHtR reached 0.48, the cardiovascular risk factors of fasting blood-glucose, blood pressure, and blood fat were signiifcantly higher. Conclusion: The 85th percentile value of WC and 0.48 of WHtR are the appropriate boundary values in increasing the cardiovascular disease risk factors in Chinese children and teenagers. WC and WHtR as a relatively simple inspection method, can well predict cardiovascular diseases, and be used in the conventional measuring items among students.

OBJECTIVE@#To investigate the relationship between postmortem interval (PMI) and the metabolic law of the amount of DNA in cells.@*METHODS@#After different PMI from the heart, liver, spleen and kidney were taken into pieces respectively, then centrifuged and digested to get suspending cells fluid. The amount of DNA of rats'viscera were detected by flow cytometry after stained by fluorescence, and also inspect the amount of DNA in different periods to find out the law of its variation.@*RESULTS@#It showed a descendent trend of the amount of DNA in cells after different PMI, especially in spleen.@*CONCLUSION@#The amount of DNA of all the viscera grows downwards after death, this might be applyed in forensic estimation of PMI.
