P-glycoprotein expression influences the result of 99mTc-MIBI scintigraphy in tertiary hyperparathyroidism 总被引:2,自引:0,他引:2

Precise localization of parathyroid glands using 99mTc-labeled hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI) scintigraphy could be affected by various biological factors. There is increasing evidence that radiotracer retention could be controlled by members of multidrug resistance (MDR) system, especially P-glycoprotein (P-gp). Since the role of P-gp in tertiary hyperparathyroidism (T-HPTH) scintigraphic studies is poorly recognized, the aim of the study was to compare the correlation between parathyroid P-gp expression and results of their scintigraphy in T-HPTH versus primary hyperparathyroidism (P-HPTH). P-HPTH (n = 19) and T-HPTH (n = 18) patients were subjected to 99mTc-MIBI scintigraphy followed by surgical treatment. The parathyroid glands were assessed in routine hematoxylin-eosin staining and P-gp expression was analyzed using immunohistochemistry. Parathyroids collected during cadaver donor multi-organ harvesting were used as a control. It has been found that P-HPTH-derived parathyroid glands with predominating adenoma morphology expressed less P-gp, as compared to P-gp-rich T-HPTH glands, mainly displaying nodular or diffused hyperplasia phenotype. This finding reversely correlated with results of 99mTc-MIBI scintigraphy. However, we did not observe any difference in P-gp expression nor scintigraphy result between nodular or diffused hyperplasia. Altogether, these data suggest that P-gp overexpression in T-HPTH could be responsible for decreased sensitivity of 99mTc-MIBI scintigraphy in those patients. Therefore, the recently proposed reduced neck exploration or limited parathyroid resection on the basis of scintigraphy could create the risk of persisted/recurrent hyperparathyroidism. However, this problem requires further study. 相似文献

PURPOSE: In this study, we investigated the penetration of various proteins into the mouse eye after a periocular injection of the protein or an adenoviral vector (Ad) expressing the protein. METHODS: At several time points after the injection, the retina, retinal pigmented epithelium/choroid, and sclera were dissected and enzyme-linked immunosorbent assays were performed. RESULTS: After a periocular injection of AdsFlt-1.10, AdTGFbeta.10, or AdPEDF.11, choroidal levels of pigment epithelium-derived factor (PEDF) and transforming growth factor-beta (TGF-beta) were not significantly different from scleral levels, and choroidal levels of sFlt-1 (soluble Flt-1 or soluble VEGF receptor 1) were only moderately reduced from scleral levels, indicating that each of these proteins penetrate the sclera well. In contrast, retinal levels of each of the three proteins were low compared to choroidal levels, suggesting poor penetration into the retina. Levels of PEDF in the choroid peaked 2 h after a periocular injection of PEDF protein and returned to baseline between 6 and 24 h, and peak levels in the retina were 8.6% of peak choroidal levels. Levels of green fluorescent protein, a protein unlikely to have any binding sites in mouse tissues, peaked in the choroid 2 h after the periocular injection and were undetectable by 4 h, while peak levels in the retina were 64.3% of peak choroidal levels. CONCLUSIONS: These data suggest that size and binding characteristics of proteins are likely to influence their ability to penetrate the eye from the periocular space, but in general, proteins as large as 50-75 kDa penetrate well into the choroid, but not into the retina. Periocular injections are feasible for the treatment of choroidal neovascularization with proteins or vectors that express them, but additional investigations are needed before they can be considered for treatment of retinal diseases. 相似文献

The aim of the study was to calculate the amount of surgical injury caused by systematic lymphadenectomy of mediastinum in patients operated on due to non-small cell lung cancer,with uneventful postoperative course.The study group consisted of 11 patients with cancer of the right lung(Group 1).The control group consisted of 12 patients with left lung cancer(Group 2).In patients with right lung cancer systematic lymphadenectomy,while in patients with left lung cancer systematic sampling was performed.Serum IL-6 and IL-1ra concentration was measured before and after surgery,and on postoperative day 1,3,and 7,as well as in sputum at the end of surgery and in pleural fluid on postoperative day 1,by ELISA test.Peripheral blood lymphocyte(PBL) count was measured with flow cytometry.Time of surgery was higher in patients with right than left lung cancer(154.1±31.29) vs(119.6±24.81) min;P=0.008) .The number of resected mediastinal lymph nodes was higher in patients with right than left lung cancer(27.6±7.6) vs(11.1 ±8.1);P=0.00006) .Postoperative decrease of PBL was significantly higher in group 1 than 2(1.25±0.37) vs(1.75 ±0.64) ×103/μL;P=0.04) .No significant differences were found in serum,pleural fluid and sputum concentration of IL-6 and IL -1ra between groups.Negative correlation between concentration of these cytokines in pleural fluid and number of resected mediastinal lymph nodes was found(Spearman test for IL-6:r=-0.723;P<0.001;for IL-1ra:r=-0.768;P<0.001).Number of "positive" N2 lymph nodes did not correlate with pleural fluid concentration of cytokines.Systematic lymphadenectomy of the mediastinum causes immunosuppression,as measured by decreased count of PBL and a negative correlation between number of resected mediastinal lymph nodes and concentration of cytokines in pleural fluid. 相似文献

OBJECTIVES: The purpose of this study was to investigate the immune, endocrine, and metabolic correlates of burnout among women. METHODS: Forty-three participants with high and 20 participants with low scores for the Shirom-Melamed Burnout Questionnaire were compared in terms of subjective symptoms, job strain, social support, plasma levels of prolactin, tumor necrosis factor alpha (TNF-alpha), transforming growth factor beta (TGF-beta), C-reactive protein (CRP), neopterin, serum levels of dehydroepiandrosterone sulphate (DHEAs), progesterone, estradiol, cortisol, and glycated hemoglobin (HbA1C) in whole blood. RESULTS: Besides reporting more job strain, less social support at work, and higher levels of anxiety, depression, vital exhaustion (VE), and sleep impairments, participants with high burnout manifested higher levels of TNF-alpha and HbA1C, independent of confounders including depression. CONCLUSIONS: Among women, burnout seems to involve enhanced inflammatory responses and oxidative stress. 相似文献

For the assessing the incidence of mood disturbances among the neurological out-patients 3287 of them were examined by 111 neurologists during their routine practice. Early diagnosis, the type of mood disturbances and the depth of depression were estimated by the use of Beck's Depression Inventory, the questionnaire based on The Mini-International Neuropsychiatric Interview and Hamilton Depression Rating Scale, as well. Around half of the patients (50.47%) were suspected on depression, as an early diagnosis. In suspected and diagnosed depressive patients the symptoms as anxiety, low activity precordial pain, headaches, dry mouth, constipation, sleep and appetite troubles were significantly (p < 0.01) more frequent than in euthymic subjects. Among all studied patients the episode of depression were found as a final diagnose in 17.2%, recurrent depressive disorders--in 17.6% and dysthymia--in 2.8% of subjects. In finally diagnosed depressive patients the chronic neurological problems were significantly (p = 0.013) more frequent, as the cause of the visit, than in the euthymic ones. The low mood was equally frequent among the patients with Parkinson's disease, multiple sclerosis and cerebrovascular disorders, as well. 相似文献
