Methods: CT ?ndings of 131 cavitary metastatic nodules in 40 patients with pathologically-proved pulmonary metastases were retrospectively analyzed. A comparison between CT signs and the pathologic types of the primary tumors was made. Results: Cavitary metastases and multiple solid nodules coexisted in all patients. Cavitary metastases presented as bubble (n=41), irregular (n=33), cystic (n=26) or small circular (n=31) cavities, with even (n=61) or uneven (n=70) thickness of the cavity wall. Of 131 cavitary nodules, diameter less than 15 mm was seen in 44, between 15–25 mm in 66, 25–40 mm in 17 and larger than 40 mm in 4 respectively. And the wall thickness of the cavity below 4 mm, between 4–15 mm and over 15 mm was respectively seen in 69, 44 and 18 metastatic nodules. Cavitary pulmonary metastases mainly occurred in patients whose primary malignancy was squamous cell carcinoma (n=13) or adenocarcinoma (n=22). Both squamous cell carcinoma and adenocarcinoma had its own CT characteristics. The occurrence of cavity bore no relationship to its site in the lung. Conclusion: Cavitary pulmonary metastases carries certain CT features and its occurrence is related to the pathologic type of the primary malignancy.展开更多

Methods: The clinical manifestation,imaging changes, pathologic subtypes, treatment and overall survival of 11 patients with PLRS wereanalyzed retrospectively. Results: Of the 11 patients diagnosed with PLRS by histopathology, thetumor of 2 patients occurred in trachea and the other 9 in lung. Cough, dyspnea and fever were themost frequent symptoms. Mass or infiltrative changes could be found on the chest X-ray and/or CTscan. Two patients were diagnosed as having Hodgkin's Lymphoma (HL) and 9 having non-Hodgkin'sLymphoma (NHL), including 7 patients with low degree NHL [5 of them (55.6%) were mucosa-associatedlymphoid tissue (MALT) lymphoma] and 2 with intermediate degree NHL. Of 10 patients undergoingexploratory thoracotomy and surgical treatment, 8 received adjuvant chemotherapy and 2 adjuvant ofradiotherapy. The remaining patient was subjected to combined chemotherapy. Both of HL patientssurvived more than 5 years without clinical disease. The median survival of MALT lymphoma and othertype of NHL was 39 months and 34 months respectively. Conclusion: Both the clinical manifestationand imaging changes are non-specific. The diagnosis was made through exploratory thoracotomy (10cases) and fiber-optical bronchoscopy (1 case). MALT lymphoma is the most frequent pathologicsubtype. Majority of patients are diagnosed and treated by surgical resection. The prognosis isacceptable.展开更多

The test has also been utilized in academia to enhance instructor＇s knowledge of the different learning styles and thus allows them to develop strategies to increase students＇ learning. The test is a forced-choice self-reporting exam comprised of 126 questions. Based on Jung＇s theory of personality type, the test seeks to categorize personality types into 16 discrete groups based on the four preference poles （Myers, 1962）. The poles are based on the preference for： （1） introversion （I） or extroversion （E）; （2） sensing （S） or intuition （N）; （3） thinking （T） or feeling （F）; and （4）judging （J） or perception （P）. Laribee （1994） studied American accounting students and found that certain personality traits were over represented in upper-level accounting courses, while Macdaid, McCaulley, and Kainz （1986） found that the same personality trait groups were over-represented in the profession. Oswick and Barber （1998）, however, found no significant relationship between the grade earned in an introductory accounting course and the personality traits as identified by the MBTI with 344 UK-based accounting students. This study investigates the relationship between a student＇s academic success in a financial accounting principles course and the MBTI personality type indicators. The type distribution of 59 historically black colleges and universities＇ （HBCU） business administration majors was analyzed and separated into two groups. The groups were then tested to determine if there was a significant difference in the mean grade of the groups in accounting principles.展开更多
