ABSTRACT
Objective To assess the value of thinprep liquid based cytology test (TCT) and Besthesda system (TBS) in diagnosis of cervial lesions. Methods 11000 cases of cervical lesions were detected with TCT and TBS.The samples of atypical squamous cells(ASC) and more severe than ASC lesions were classified into postive cytology,and then cytological results were compared with pathological examination results of cervical biopsies.Results The satisfactory rate of TCT samples was 96.36%, and the postive rate of abnormal epithelial cells diagnosed by TCT was 10.96%(1206/11000). Among 1206 cases, 15 cases(0.14%) of CA, 89 cases (0.81%) of HSIL, 449 cases (4.08%) of LSIL, 73 cases (0.66%) of ASC-H and 580 cases (5.27%) of ASC-US and AGUS. 1128 cases with postive cytologic results received pathological examination. The pathological positive rate of CA, HSIL, LSIL, ASC-H, and ASC-US and AGUS were 100%, 100%, 67.12%, 54.17% and 14.09%, respectively. The coincident rate of two examination methods was 100% for CA, 91.1% for HSIL,57.82% for LSIL and 27.78% for ASC-H. Conclusion TCT and TBS can accurately detect cervical cancer, precancerous lesions and infection of bacteria, virus and other pathogens, and at present is a means of screening cervical cancer.
ABSTRACT
Totally 126 patients with malignant breast tumors diagnosed with ultrasound were followed up.The ultrasonic image characters were analyzed and compared with the pathologic outcomes. Ultrasound had a 92.1%(116/126) veracity in the diagnosis of malignant breast tumor,which were characterized by strong echo in the border of the tumors and halo (72.2%, 91/126).There were differences in ultrasonic images of malignant breast tumors with different pathologic types. Ultrasound can determine the character of most breast tumors.
ABSTRACT
AIM To investigate the possibility of microvolume rodent ventilator in improving the quality of global ischemia-reperfusion injury model in mice. METHDOS Global cerebral ischemia-reperfusion injury was preduced in mice by obstructing and decompressing bilateral common carolid arteries and pressuring and decompressing cervical soft tissue, artificial respiration was performed using rodent ventilator before those procedures. EKG, ECG was detected and pathological examination. RESULTS Rodent ventilator was used to keep essential physiologic ventilative volume befer pressure, EKG change was not been found in observed duration in all animals. The suppressed cephalograph was displayed continuously in various time in ischemic and reperfusion injury. Pathological examination indicated that the damage was worse progressly in cerebral cortex and hippocampus, as times of ischemic and reperfusion prolonged. CONCLUSION Using microvolume rodent ventilator success rate and stability is increased obviously in model of global cerebral ischemia-reperfusion injury in mice and mortality was decreased greatly.
