Objective To evaluate the effectiveness of color doppler ultrasound(CDU)in combination of computed tomographie angiography(CTA)in diagnosis of the arteriosclerosis occlusion.Methods:43 patients with arteriosclerosis occlusion were assessed by color doppler ultrasound,CTA and digital subtraction angiography(DSA).By using DSA as the reference standard,the results were compared.Results The sensitivity.specificity,positive and negative predictive values for CDU were 82.96%,95.2%,94.92%,83.8% respectively.Those for CTA were 88.89%,96.75%,96.77%,88.81% respectively,and for the two combination,were 94.81%,99.17%,99.22%,94.44% respectively.Conclusion The color doppler ultrasound combined with CTA is an effective way in diagnosing arteriosclerosis occlusion.

typeⅢgold alloy. Candida albicans could be found on acrylic resin ,but there was little on the other 4 dental metals. Conclusion: From the perspective of reserving periodontal tissue, pure-Ti and typeⅢgold alloy seem to be the first choice, Co-Cr alloy and Ni-Cr alloy are the second.

OBJECTIVE:To optimize the preparation technology for enteric-coated changbiqing granules.METHODS:The concentration of acrylic resin and the four factors like the quantity of castor oil,pulvis talci and methylsilicone oil on the yield of changbiqing enteric-coated granules were determined by orthogonal test design;The effects of the enteric-coated granule plasticizer on the quantity of castor oil and the weight increment of the coating were determined by the release rate test.RESULTS:The optimized formula of the coating solution was described as follows:the concentration of acrylic resin was5%,the relative amount of castor oil to acrylic resin was35%,the dosages of pulvis talci and methylsilicone oil were3%and1%,respectively,the weight increment of the coating was30%.CONCLUSION:Changbiqing enteric-coated granules pre?pared on the optimized technology are in line with the quality requirements and which have ideal enteric soluble drug releasing characteristics.

objective To understand the baseline data of mortality from malignant tumor from 2006 to 2009 around Hongyanhe Nuclear Power Plant in Wafangdian City,Liaoning Province,so as to provide scientific basis for evaluating the impact of normal operation of nuclear power plant on the health of the residents nearby.Methods Thirty small towns near Hongyanhe Nuclear Power Plant were divided into 5 investigated areas according to the distances away therefrom(0.,10.,20-,30-,and 40-km).The data about from malignant tumor were obtained from the Center for Disease Control and Prevention of Wafangdian.The mortality distribution of difierent malignant tumors was analyzed,including the radiosensitive malignant tumors,especially leukemia,breast cancer,and thyroid gland cancer in different area,gender,and age groups.Results The mortality from malignant tumor was 151.97/105,and the standardized mortality rate(SMR)was 97.76/105.The mortality from malignant tumor among the males was 188.28/105(with the SMR of 116.76/105),and that among the females was 113.47/105(with the SMR of 75.89/105).with a sex ratio of 1.71.The first five cancers in the rank of death causes were lung,liver,stomach,colorectal,and esophageal cancers with mortality of 46.19/105,23.51/105,20.30/105,8.06/105 and 5.45/105,respectively.The mortality from mal.ignant tumor in the areas around the nuclear power plant from the near to the distant were 99.85/105, 137.40/105,138.73/105,156.30/105,and 154.16/105,respectively.The mortality from radiosensitive malignant tumors,leukemia,breast cancer,and thyroid gland cancer were 4.57/105,4.06/105,and 0.26/105,respectively.Conclusions Lung cancer and digestive tract malignant tumors are the main causes of death from malignant tumors in Wafangdian area before the nuclear power plant began to operate.There are no significant differences in the mortality distribution of malignant tumors among different areas,genders,and age groups.There are not significant differences in the mortality distribution of leukemia and breast cancer among different areas and age groups.
