Objective To discuss the diagnostic value of color Doppler echocardiography in small coronary-to-pulmonary fistula (SCPF) in children. Methods The clinical data of children who were diagnosed CPF by color Doppler echocardiography during 2011-2012 in my hospital were analyzed retrospectively. Results Seventeen cases with CAF including one diagnosed by forensic report and 8 cases diagnosed by AGA. Conclusion The results indicated that SCPF detection rate could be improved largely by observing spraying-up sign experienced in pulmonary artery diastolic combined with rich flow signal of coronary in color Doppler. In addition, it is valuable to diagnose children's SCPF by color Doppler echocardiography.

Objective: To explore the current prevalence of dyslipidemia in adult population of 9 provinces of China and the epidemic characteristics of this disease. The potential influence of social economic development on dyslipidemia was also observed. Methods: Present research data are derived from the result of the investigation about survey on health and nutrition in China in 2011, in which multistage stratified cluster random sampling method was adopted to investigate the 24 345 individuals in 216 communities from 9 provinces in China and 10 242 blood samples were collected. In this research, 8 669 blood samples of people over 18 years old were selected for final analysis. After adjustment of age, the percentage of dyslipidemia patients in Chinese adults was calculated. Results: The percentage of dyslipidemia in Chinese adults is 39.91% (3 460/8 669). The percentage of dyslipidemia at the age of 18-24, 35-44, 45-59 and over 60 years old were 30.25% (373/1 233),37.19% (774/2 081), 44.22% (1 304/2 949) and 41.94%(1 009/2 406),respectively (χ²=333.02, P<0.01); the percentage of dyslipidemia in male and female population was 51.11% (1 956/3 827) and 31.06%(1 504/4 842), respectively (χ²=60.35, P<0.01); the percentage of dyslipidemia in urban residents and rural residents was 42.56% (1 144/2 687) and 38.72%(2 316/5 982), respectively (χ²=11.72, P<0.01);the percentage of dyslipidemia in high-GDP regions and low-GDP regions was 43.04% (1 567/3 641) and 37.65% (1 893/5 028), respectively (χ²=25.57, P<0.01) .The prevalence of adult hypercholesterolemia in Chinese adult is 9.01% (781/8 669), the prevalence of borderline increased cholesterol is 22.54% (1 954/8 669), the prevalence of hypertriglyceridemia is 27.02% (2 342/8 669), the prevalence of lower high-density lipoproteinemia is 14.36% (1 245/8 669) and the prevalence of increased low-density lipoproteinemia was 10.23% (887/8 669). All prevalence rates are significantly higher compared to the 2005 survey results. Conclusion The prevalence of dyslipidemia in Chinese adults is high and the prevalence increases in a fast pace. The current situation of dyslipidemia in Chinese adults is critical and targeted strategies should be applied to control the dyslipidemia in adult Chinese population.
