Primary Non-Hodgkin's Lymphoma of the Liver 总被引:3,自引:0,他引:3

The clinicopathological features of a rare case of primary non-Hodgkin's hepatic lymphoma (PHL) are described and compared to those of the other 76 cases reported in the world literature. PHL is mainly a disease of Caucasian, middle-aged males and, in approximately half of the reported cases, was associated with other diseases involving depression or chronic stimulation of the immune system. Right upper abdominal and epigastric pain with loss of weight are the most common presenting symptoms. The tumour is usually a single large mass involving both hepatic lobes and is almost invariably composed of lymphocytes reacting with B-cell markers. Most tumours are of intermediate or high grade according to the classification of the Working Formulation for Clinical Usage. No correlation is apparent between gross appearance of PHL (massive or nodular) and grade of severity. Chemotherapy or radiotherapy alone appears to be ineffective, while relatively good results can be obtained with combination modalities. 相似文献

Activity-rest stimulation protocol improves cardiac assistance in dynamic cardiomyoplasty. 总被引:1,自引:0,他引:1

OBJECTIVE: No data have ever been published regarding cardiac assistance in demand dynamic cardiomyoplasty (DDCMP). We tested the efficacy of the Doppler flow wire in measuring beat-to-beat aortic flow velocity and evaluating cardiac assistance in demand cardiomyoplasty patients. METHODS: The technique was tested in seven patients (M/F=6/1; age=57.1+/-6.2 years; atrial fibrillation/sinus rhythm=1/6; NYHA=1.4+/-0.5). Measurements were done using a 0.018inch peripheral Doppler flow wire advanced through a 5F arterial femoral sheath. Three 1-min periods with the stimulator off and three 1-min periods with clinical stimulation were recorded. We measured peak aortic flow velocity in all beats. Latissimus dorsi (LD) mechanogram was simultaneously recorded. RESULTS: Comparison between pre-operative and follow-up data showed significantly higher values of tetanic fusion frequency (TFF) and ejection fraction at follow-up, whereas mean NYHA class was significantly lower. Statistical analysis showed an increase in aortic flow velocity not only in assisted versus rest period, but also in assisted versus unassisted beats (8.42+/-6.98% and 7.55+/-3.07%). A linear correlation was found between the increase in flow velocity and LD wrap TFF (r(2)=0.53). CONCLUSIONS: In DDCMP, systolic assistance is significant and correlated to LD speed of contraction; demand stimulation protocol maintains muscle properties and increases muscle performance. 相似文献

BACKGROUND:
The authors investigated whether early stage lung cancer could be identified by proteomic analyses of plasma.METHODS:
For the first case‐control study, plasma samples from 52 patients with lung cancer and from a group of 51 controls were analyzed by surface‐enhanced laser desorption/ionization time‐of‐flight mass spectrometry. In a second case‐control study, a classifier of 4 markers (mass‐to‐charge ratio, 11,681, 6843, 5607, and 8762) also was tested for validation on plasma from 16 consecutive patients with screen‐detected cancer versus 406 healthy individuals. The most relevant marker was identified, and an enzyme‐linked immunosorbent assay‐based analysis revealed that signal intensity was correlated with concentration.RESULTS:
The classifier had a sensitivity of 94.23% and a specificity of 76.47% in the first study but lost predictive value in the second study. Nevertheless, the 11,681 cluster, which was identified as serum amyloid protein A (SAA), resulted in a multiple logistic regression model that indicated a strong association with lung cancer. When both studies were considered as a together, the odds ratio (OR) for an SAA intensity ≥0.5 was 10.27 (95% confidence interval [CI], 4.64‐22.74), whereas an analysis restricted to stage I cancers (TNM classification) revealed an OR of 8.45 (95% CI, 2.76‐25.83) for T1 lung cancer and 21.22 (95% CI, 5.62‐80.14) for T2 lung cancer.CONCLUSIONS:
SAA levels were predictive of an elevated risk of lung cancer, supporting the general view that inflammation is implicated in lung cancer development. Cancer 2010. © 2010 American Cancer Society. 相似文献140.
