Methods： CD 13 expression in peripheral blood lymphocytes and skin lesions was detected by flow cytometry and imrnunohistochemical technique, respectively. Results were compared with those of healthy controls. Results： CD 13 expression was significantly higher in peripheral blood lymphocytes of patients with advanced psoriasis vulgaris than in that of healthy controls, and in skin lesions than in healthy skin tissues. The expression was mainly in the suprabasal layers of skin lesions, and positively correlated to PASI （R 0.78029）. Conclusion： The significantly higher expression of CD13 in peripheral blood lymphocytes and skin lesions of the patients with advanced psoriasis vulgaris probably is related to immunological abnormality, blood vessel abnormality and proliferation of keratinocyte in the pathogenic course of psoriasis. It may be a novel and effective way to treat psoriasis with specific CD13 inhibitors.展开更多

METHODS: 46 consecutive patients, referred to a gastroenterologist and surgeon for a symptomatic or incidental pancreatic cyst, were reviewed. EUS, cytology, and carcinoembryonic antigen (CEA) and carbohydrate antigen (CA 19-9) levels were compared with the final diagnosis, based on surgical pathology and/or imaging follow-up of at least 12 mo. Cysts were classified as benign (pseudocyst, serous cystadenoma) or malignant/ pre-malignant (mucinous cystic neoplasm). Receiver- operator characteristics (ROC) curve analysis was performed. RESULTS: The mean age was 56 years; 29% were male and median cyst diameter was 3 cm. Final outcome was obtained in 41 (89%) patients. Twenty-three (56%) of these 41 had surgical pathology. Twenty-three (56%) had benign lesions and 18 (44%) had malignant/pre- malignant lesions. Sensitivity, specificity and positive and negative predictive value of EUS alone to distinguish benign from malignant/premalignant pancreatic cystic lesions were 50%, 56%, 36% and 54% and for cytology were 71%, 96%, 92% and 85%, respectively. The corresponding values for the ROC-derived ideal cutoffswere 75%, 90%, 75%, 90% for CA 19-9 (> 37 U/mL) and 70%, 85%, 79% and 78% for CEA (> 3.1 ng/mL). Subgroup analysis of those with surgical pathology yielded almost identical performance and cutoffs. CONCLUSION: Cytology and cyst fluid tumor marker analysis is a very useful tool in distinguishing benign from (pre)malignant pancreatic cystic lesions.展开更多

In recent years, Traditional Chinese Medicine(TCM) has attracted widespread attention in the treatment of psoriasis because of better efficacy and a lower incidence of adverse reactions. In TCM, psoriasis is considered to be caused by blood heat and the stagnation of Qi and blood. This article primarily investigated the key points of common syndromes, TCM nursing methods and healthy guidance of psoriasis vulgaris, aiming at maintaining and developing the strengths of TCM, improving its efficacy and standardizing its behavior.展开更多

Imaging results were compared with histopathology when available, or clinical and radiological follow-up of at least 1 year. For each technique we calculated: Sensitivity (Se), specificity (Sp), overall accuracy, positive and negative predictive values, error rate, and Youden’s index. McNemar’s χ<sup>2</sup> test was used to test the difference in sensitivity and specificity between the two diagnostic methods. All analyses were computed on a patient basis, and then on a lesion basis, with consideration ofthe density of independent lesions on the co-registered CT (sclerotic, lytic, mixed, no-lesions) and the divergent site of disease (skull, spine, ribs, extremities, pelvis). The impact of adding <sup>18</sup>F-NaF PET/CT to the work-up of patients was also measured in terms of change in their management due to <sup>18</sup>F-NaF PET/CT findings.RESULTS: The two imaging methods of <sup>18</sup>F-FDG and <sup>18</sup>F-fluoride PET/CT were significantly different at the patient-based analysis: Accuracy was 86.7% and 84.4%, respectively (McNemar’s χ<sup>2</sup> = 6.23, df = 1, P = 0.01). Overall, 244 bone lesions were detected in our analysis. The overall accuracy of the two methods was significantly different at lesion-based analysis (McNemar’s χ<sup>2</sup> = 93.4, df = 1, P < 0.0001). In the lesion density-based and site-based analysis, <sup>18</sup>F-FDG PET/CT provided more accurate results in the detection of CT-negative metastasis (P < 0.002) and vertebral localizations (P < 0.002); <sup>18</sup>F-NaF PET/CT was more accurate in detecting sclerotic (P < 0.005) and rib lesions (P < 0.04). <sup>18</sup>F-NaF PET/CT led to a change of management in 3 of the 45 patients (6.6%) by revealing findings that were not detected at <sup>18</sup>F-FDG PET/CT.CONCLUSION: <sup>18</sup>F-FDG PET/CT is a reliable imaging tool in the detection of bone metastasis in most cases, with a diagnostic accuracy that is slightly, but significantly, superior to that of <sup>18</sup>F-NaF PET/CT in the general population of breast cancer patients. However, the extremely high sensitivity of <sup>18</sup>F-fluoride PET/CT can exploit its diagnostic potential in specific clinical settings (i.e., small CT-evident sclerotic lesions, high clinical suspicious of relapse, and negative <sup>18</sup>F-FDG PET and conventional imaging).展开更多
