Objective To analyze the distribution and evolution of the risk factors for coronary heart disease (CHD) in middle-aging males, and provide the evidence for the prevention and treatment of male patients with CHD. Methods 1639 male people over 45 years old were enrolled in the study. They were divided into non- senile group (45-59 years old) and senile group (60-93 years old).The subjects over 60 years old were further divided into three groups:60-69 years old group, 70-79 years old group, 80-93 years old group. The interrelation between the risk factors of CHD and aging was analyzed. Results The prevalence rates of drinking, smoking, diastolic hypertension and low HDL-C in non-senile group were much higher than those in senile group (x2=28.80,18.35,15.72,17.84,P<0.01). In contrast, the prevalence rates of overweight, systolic hypertension, fasting hyperglycemia,postprandial hyperglycemia in senile group were significantly higher than those in non senile group. The prevalence rates of high triglyceride in non- senile group and senile group were 18.0% and 16.2% respectively(P>0.05). The prevalence rates of high cholesterol in non- senile group and senile group were 36.9% and 31.5% respectively(P>0.05). There was a significant decrease in the prevalence rates of overweight, postprandial hyperglycemia (P<0.05) and drinking,smoking, diastolic hypertension, high triglyeeride (P<0.01) in over 70-year+old males. And the prevalence rates of overweight, postprandial hyperglycemia, high triglyceride of over 80-year-old males were higher than those of over 70-year-old males (x2=10.05,4.16,5.97,P＜0.01). However,the prevalence rates of systolic hypertension of over 80-year-old males were lower than those of over 70-year-old males (X2=21.25,P＜0.01). There was no significant change in other risk factors of CHD at different ages of senile group. Conclusions For non-senile males, the important measures to treat the risk factors of CHD should include stopping smoking, restricting alcohol, eating low fat diet, changing bad life habits, controlling diastolic hypertension and modifying lipid. In contrast, for senile males, more attention should he paid to limiting total energy intake, increasing sports, losing weight, controlling systolic hypertension, hyperglycemia and modifying lipid.

Objective To investigate the application of microemulsion thin layer chromatography (TLC) for separation and identification of various active components in Xinnaomaitong capsule .Methods The all-grass of Bluecalyx japanese rabo-dosia,rootof Puerarialobata,rootandrhizomeof Salviamiltiorrhiza,rhizomeof LigusticumchuanxionginXinnaomaitong capsule were separated and identified simultaneously with the polyamide film as stationary phase and the microemulsion as mo-bile phases .Different factors ,such as the sodium dodecyl sulfate (SDS) ,oil phase and water phase which effect on the separa-tion of the components were evaluated .Results The all-grass of Bluecalyx japanese rabodosia ,root of Pueraria lobata ,root andrhizomeof Salviamiltiorrhiza,rhizomeof LigusticumchuanxionginXinnaomaitongcapsulewereseparatedandidentified simultaneously with mobile phase of microemulsion∶formic acid∶acetone (5∶1∶1) .The constituent of microemulsion was SDS∶butyl alcohol∶n-Heptane∶water = 6 .7∶15 .8∶2 .5∶75 .0 (g/g) .The spots were clear ,the negative control was no interference ,and it showed an ideal separation .Conclusion Microemulsion TLC is simple ,accurate ,and reproducible .It can identify a variety of active components in traditional Chinese medicine simultaneously .
