A long term follow-up study on the nonsurgical therapy of abdominal aortic aneurysm in senile patients / 解放军医学杂志

Objective To study the course of development of aneurysm of abdominal aorta (AAA) with nonsurgical treatment in senile patients. Methods 37 subjects were included in the study, and they were divided into 3 groups according to the size of aneurysm observed at the first visit. The diameter of aneurysm was measured, and the measurement was repeated at periodic follow up. The yearly increase of the diameter was calculated and analyzed. Results For the 37 patients, the AAA mean diameter was 4.68cm at the first visit. The period of follow-up was 0.5 to 11 years, with a mean of 6.1 years. The average yearly increase in tumor diameter was 0.47cm/year. 14 patients with aneurysm diameter of 6.0cm had an average increase of 0.67cm/year. 5 patients died during the follow-up period, 2 of them died of rupture of the aneurysm, the diameter of which was 8.35cm and 8.91cm, respectively. Endoaneurysmorrhaphy with stent was performed in 7 patients. Conclusion The size of AAA in the senile patients increased slowly if the aneurysm diameter is 6.0 cm, the tumor size might increase quickly, and active intervention is recommended.

The relationships between Ultrasonographic Features and the Expression of estrogen receptor and progesterone receptor in Postmenopausal Women with Infiltrating Ductal Carcinoma of Breast / 解放军医学杂志

Objective To investigate the relationships between of 2-dimensional (2D) and color Doppler ultrasonographic features and the expressions of both estrogen receptor (ER) and progesterone receptor (PR) in postmenopausal women with infiltrating ductal carcinoma (IDC) in breast, and to evaluate the feasibility of predicting the expressions of ER and PR in IDC by means of ultrasonographic features. Methods The clinical data of 96 patients with breast infiltrating ductal carcinoma diagnosed by pathology during Jun. 2002 to Jun. 2007 were retrospectively analyzed. The correlation between ultrasonographic features and both ER and PR expressions in the mastectomy specimens determined by immunohistochemical technique was statistically analyzed. Results Of the 96 cases, the positive expression rates of ER and PR were 54.17% and 50%, respectively, the bi-positive and bi-negative expression rates of ER and PR were 41.67% and 37.5%, respectively. Among the breast carcinoma, the positive expression rate of ER was higher in tumor with ultrasonographic spicule sign (P
