Objective To compare the diagnostic value of ultrasound,molybdenum target,magnetic resonance(MRI)and single examination for breast cancer.Methods From January 2017 to February 2018,100 patients with suspected breast cancer in Lishui Central Hospital were selected in the study.All patients were detected by ultrasound,mammography and MRI three ways for diagnosis.The results were verified with postoperative pathologic results as the standard.The diagnosis accuracy of three ways for breast cancer were analyzed.Results The detection accuracy of three ways joint detection in patients with breast cancer was the highest(91.00％),which was significantly higher than that of ultrasound(63.00％),mammography(72.00％)and MRI(72.00％)in single mode,the differences were statistically significant(χ2 =22.364,20.154,16.032,all P<0.05).Conclusion Ultrasonography,molybdenum target X ray and MRI have their respective advantages in the process of breast cancer differentiation and diagnosis,and the detection rate can be significantly improved if combined use.

Objective: To investigate the clinical effect of percutaneous transhepatic bile duct drainage guided by ultrasound. Methods: From June 2016 to June 2018, 100 patients with obstructive jaundice in Lishui Central Hospital were treated with ultrasound-guided percutaneous transhepatic bile duct drainage.The success rate and postoperative complications of the patients were analyzed. Results: Among 100 cases, 98 cases were successful, 2 cases failed, and the failure rate was 2%.The success rate of one-time catheterization in 0.5-2.0 cm patients with intrahepatic bile duct diameter(98.91%) was significantly higher than that in intrahepatic bile duct diameter 0.3-0.4 cm patients(87.50%), compared with two different diameter puncture catheterization, the difference was statistically significant(χ²=12.369, P<0.05). All 98 cases with successful puncture were followed up after operation (P<0.05), and there was no statistically significant difference between the two groups(P<0.05). The drainage tube was removed in 2 cases, bile duct infection was found in 2 cases, the remaining patients were unobstructed, and there were no obvious complications. Conclusion Ultrasound-guided percutaneous transhepatic catheterization and drainage for the treatment of obstructive jaundice caused by malignant tumor is simple, reliable, safe and effective, and has a certain clinical value.It is worthy of popularizing and application.

Objective To evaluate the value of ultrasound elastography combined with serum markers in the assessment of chronic hepatitis B fibrosis. Methods 100 patients with chronic hepatitis B liver fibrosis who were diagnosed and treated in our hospital from January 2015 to December 2017 were randomly selected. All patients were given hepatic histopathological tests, serological tests, and ultrasound elastography. The liver biopsy results were taken as the final diagnosis results. The accuracy of classification of hepatitis B fibrosis by the combined diagnosis of ultrasound elastography and serum markers was observed. Results The total accuracy of the combined examination was 91.00％ with histological examination as the final results. There was no statistically significant difference between the results of the two examinations (P>0.05). The ultrasound elastography score and FIB4 score in the patients with hepatitis B fibrosis grade F1-F4 were increased along with the increase of grade, and there was statistically significant difference (P<0.05). Conclusion Ultrasound elastography combined with serum markers has an important clinical value in the assessment of the degree of chronic hepatitis B fibrosis. It is non-invasive, easy to operate and highly accurate, and can provide a reliable basis for disease diagnosis and staging.
