The system involving angiopoietin-2 (Ang-2) and its receptor, Tie-2, appears to play an important role not only in tumor angiogenesis, but also in the biology of haematological and non-haematological malignancies. In the present study we evaluated the serum levels of soluble Ang-2 (sAng-2) and soluble Tie-2 (sTie-2) in patients with haematological malignancies. Measurements were carried out in 15 patients with chronic myeloid leukaemia (CML), 25 with essential thrombocythemia (ET), 24 with multiple myeloma (MM) and six with monoclonal gammopathy of undetermined significance (MGUS). In addition, we correlated the levels of angiopoietins with known prognostic factors. sAng-2 and sTie-2 were quantified with enzyme-linked immunosorbent assay (ELISA). In patients with CML and MM the levels of sAng-2 were significantly higher (1686.53 +/- 936.41 pg/mL and 1917.82 +/- 1427 pg/mL, respectively) than in controls (n = 15; 996.096 +/- 414.65 pg/mL) (P < 0.01). In patients with MM sAng-2 levels were significantly increased with increasing stage of disease, from stage I to stage III (P < 0.03) and presented a trend of correlation with Beta2-microglobulin levels (r = 0.317) and grade of bone involvement. Furthermore, the levels of sAng-2 determined after 6 months of chemotherapy in CML patients were significantly lower than at diagnosis in the patients who achieved haematological remission. Circulating sTie-2 levels were increased in patients with ET (17.5 +/- 9.2 vs 9 +/- 3.5 ng/mL; P < 0.01) and in those with CML (16.29 +/- 8.7 ng/mL; P < 0.04). In conclusion, abnormal levels of sAng-2 and sTie-2 are present in some haematological malignancies. These markers may play a role in the pathophysiology of these conditions and their progression. 相似文献

X-linked adrenoleukodystrophy (X-ALD) is a devastating neurological disorder caused by mutations in the ABCD1 gene that encodes a peroxisomal ATP-binding cassette transporter (ABCD1) responsible for transport of CoA-activated very long-chain fatty acids (VLCFA) into the peroxisome for degradation. We used recombinant adenoassociated virus serotype 9 (rAAV9) vector for delivery of the human ABCD1 gene (ABCD1) to mouse central nervous system (CNS). In vitro, efficient delivery of ABCD1 gene was achieved in primary mixed brain glial cells from Abcd1−/− mice as well as X-ALD patient fibroblasts. Importantly, human ABCD1 localized to the peroxisome, and AAV-ABCD1 transduction showed a dose-dependent effect in reducing VLCFA. In vivo, AAV9-ABCD1 was delivered to Abcd1−/− mouse CNS by either stereotactic intracerebroventricular (ICV) or intravenous (IV) injections. Astrocytes, microglia and neurons were the major target cell types following ICV injection, while IV injection also delivered to microvascular endothelial cells and oligodendrocytes. IV injection also yielded high transduction of the adrenal gland. Importantly, IV injection of AAV9-ABCD1 reduced VLCFA in mouse brain and spinal cord. We conclude that AAV9-mediated ABCD1 gene transfer is able to reach target cells in the nervous system and adrenal gland as well as reduce VLCFA in culture and a mouse model of X-ALD. 相似文献

Totally anomalous pulmonary venous connection to the azygos vein is a rare congenital heart malformation in which all the pulmonary venous blood returns anomalously to the azygos vein. Among 111 consecutive patients with totally anomalous pulmonary venous connection undergoing surgical correction at our institution between June 1982 and September 1997, this malformation was present in seven cases. By echocardiography, using a subxyphoid short-axis view at the atrial level and a modified suprasternal sagittal view, the malformation was diagnosed when the pulmonary venous confluence was traced posteriorly and superiorly relative to the right pulmonary artery and right bronchus, finally reaching reach the superior caval vein. Totally anomalous pulmonary venous connection to the azygos vein was misdiagnosed in the first two patients, both by echocardiography and angiocardiography. In the subsequent five patients, a precise diagnosis was obtained by echocardiography. Echocardiography, therefore, can be considered an accurate diagnostic tool permitting recognition of totally anomalous pulmonary venous connection to the azygos vein, and permitting corrective surgery without recourse to catheterization and angiography. 相似文献

At age of 57 years, a man experienced an episode of rhabdomyolysis. On that occasion muscle biopsy was not performed, however monoclonal gammopathy of undetermined significance (MGUS) was diagnosed. Further he developed a moderate proximal muscle weakness with CK level persistently elevated (1000-1200U/l). When he came to our observation, at age 67, a muscle biopsy revealed an amyloid myopathy and multiple myeloma was at the same time disclosed. Terminal complement complex C5b9 (membrane attack complex) deposits were found in the vessel walls and muscle fibers surface depicted by amyloid. Our case suggests to keep in mind the possibility that amyloid myopathy may begin as an isolate episode of rhabdomyolysis. The detection of complement complex C5b9 suggests that complement cascade is implicated in the muscular damage of amyloid myopathy. 相似文献

Prognostic value of p16‐INK4A protein in women with negative or CIN1 histology result: A follow‐up study 下载免费PDF全文

P16‐INK4A overexpression has been proposed as a prognostic marker to manage the follow up of women with positive cytology and/or HPV test but without high‐grade cervical intraepithelial neoplasia (CIN2+). This study measures the relative risk (RR) of CIN2+ of p16 positive versus negative in these women. All the women referred to colposcopy from October 2008 to September 2010 with negative or CIN1 colposcopy‐guided biopsy were included in the study; women surgically treated or having a CIN2–3 were excluded. All baseline biopsies were dyed with hematoxylin and eosin and p16. Women were followed up according to screening protocols, with cytology or colposcopy at 6 or 12 months. CIN2/3 RRs and 95% confidence intervals (95%CI) were computed. Of 442 eligible women, 369 (83.5%) had at least one follow‐up episode. At baseline, 113 (30.6%) were CIN1, 248 (67.2%) negative, and 8 (2.2%) inadequate histology; 293 (79.4%) were p16‐negative, 64 (17.3%) p16 positive and 12 (3.2%) not valid. During follow up, we found ten CIN2 and three CIN3; of these, six were p16 positive (sensitivity 46%, 95% CI 19–75). The absolute risk among p16 positives was 9.4/100 compared to 1.7/100 of the p16 negatives (RR 5.5; 95% CI 1.7–17.4). The risk was also higher for CIN1 than for histologically negative women (RR 4.4; 95% CI 1.3–14.3). The RR for p16 in CIN1 did not change (RR 5.2; 95% CI 0.6–47.5). P16 overexpression is a good candidate for modulating follow‐up intensity after a negative colposcopy but is limited by its low prospective sensitivity. 相似文献

Migraine headaches and depression often co-occur within individuals, and both syndromes run in families. However, knowledge about how these disorders relate across generations, as well as how migraine relates to other forms of psychopathology, is sparse. This study examined risk for migraine among female adolescent offspring of parents with different types of psychopathology. The sample was drawn from the Minnesota Twin Family Study, a community-based study of adolescents and their families ( n = 674, 17-year-old female adolescents and their biological parents). Diagnoses of maternal, paternal and offspring major depression, antisocial behaviour, alcohol dependence and drug dependence were based on structured interviews. Migraine headaches in each family member were assessed via interviews with the mother. Parental depression, antisocial behaviour and drug dependence were associated with offspring migraine. These associations mostly remained significant even when parental migraine and the corresponding type of psychopathology in offspring were adjusted for. In contrast, there were no significant associations between parental psychopathology and offspring stomach problems, indicating that these associations did not extend to all offspring somatic symptoms. These results emphasize the need to look at antisocial behaviour and substance-related problems when examining associations between migraine and psychopathology, and indicate that more research on inter-generational links between migraine and psychopathology is needed. 相似文献
