ABSTRACT
Objective We invented mammary lump skin-positioning membrane (named scare membrane) to facilitate localization of mammary lump during ultrasound scan.This study is to measure the radius of mammary of Chinese adult women for designing different types of skin-positioning membrane.MethodsThe radius of mammary glands in 236 cases of adult females was detected with color Doppler ultrasound at 5 different clock positions:12:00,3:00,6:00,9:00 and 10:30 or 1:30.SPSS 16.0 statistical software was used to analyze the data.The cut-off values of mammary glands radius at 99％,95％,75％ and 50％ were calculated.Paired t tests or nonparametric tests (relative sample rank sum tests) were used to verify the consistency of mammary gland radius between left and right sides.ResultsThe cut-off value of 95％ mammary gland radius was:7.700cm at 12:00,7.810 cm at 13:00,8.100 cm at 3:00,5.330 cm at 6:00 and 6.300 cm at 9:00 for left mammary gland ; 7.500 cm at 12:00,6.015 cm at 3:00,5.500 cm at 6:00,8.510 cm at 9:00 and 7.930 cm at 10:30 for right mammary gland.In comparison of left and right mammary gland radius,the difference had statistical significance between the group of left side at 1:30 and right side at 10:30,the group of left side at 3:00 and right side at 9:00(P ＜0.05).The right mamma was relatively larger.The cut-off values of the right mamma at the above two clock points were taken as radius of scale membranes while the average of percentage cut-off values at 12:00,3:00 of both mammas,left side at 9:00 and right side at 3:00 are taken as radius of scale membranes.ConclusionsAccording to the cut-off values of 99％,95％,75％ and 50％ radius of adult female mammary glands,mammary lump skin-positioning membrane radius can be classified into 4 size-types:extra large,large,medium and small.The precise classification of radius of mammary scale membranes according to mammary glands of adult females provides convenience for production,manufacture and clinical application of mammary lump skin-positioning membrane.
ABSTRACT
Objective To explore the significance of palpation-negative breast tumor resection with ultrasound-guided methylene blue labeling and percutaneous suture traction.Methods 46 cases of small breast tumors with the diameter from 0.5 cm to 1.0 cm were double labeled with methylene blue under the guide of ultrasound l hour preoperatively.The tumors were fixed,drew outward with percutaneous suture and resected accurately.All the 46 cases were rechecked by ultrasound to verify whether residual or false resection occurred 1 month later.Results All the 58 tumors of the 46 patients were accurately resected.No residue or false resection occurred.The average operation duration was 10 min to 20 min.Conclusion Palpable-negative breast tumor resection with ultrasound-guided methylene blue labeling and percutaneous suture traction has the advantages of small invasion,accurate positioning and short operation duration.
ABSTRACT
Objective: To explore the clinical significance. Methods: The double-antibody sandwich ELISA technique. Result: The serum interleukin-6(IL-6) levels of patients with cholangiocarcinoma are significantly higher than those in benign biliary disease and normal controls (P<0.05). Conclusion: Serum IL-6 levels of patients with cholangiocarcinoma are significantly increased ,it is one of the important parameters for clinical evaluation in patients of cholangiocarcinoma.
