We experienced the case of an 82-year-old man with chronic neutrophilic leukemia (CNL) with dysplastic features in the granulocytic lineage which subsequently progressed to acute myeloblastic leukemia (AML) with myelofibrosis. The patient had hepatosplenomegaly, but there was no evident cause of neutrophilic leukocytosis. The cytogenetic study showed that he had a normal karyotype. Concentrations of the serum granulocyte colony-stimulating factor (G-CSF) were not detectable. Two years after the diagnosis of CNL, blastic transformation to AML occurred with myelofibrosis and significant morphological abnormalities in neutrophils. The blasts were positive for myeloperoxidase, CD33, CD34, and HLA-DR, and the presence of dysplasia within the granulocytic lineage suggested that he had an abnormality at the level of the granulocyte-committed progenitors. Heterogeneous origins of CNL might lead to various clinicopathological features in each case. 相似文献

Endoscopic gallbladder stenting is useful palliative therapy for acute cholecystitis in high‐risk patients. Although the success rate of endoscopic gallbladder stenting is 79%–100%, an alternative method has not been reported. We succeeded in employing a method for percutaneous gallbladder stenting (PTGS) and herein describe this new method. A patient with acute acalculous cholecystitis related to ischemic atherosclerotic vascular disease, cholangitis due to Lemmel syndrome, and severe congestive heart failure underwent PTGS through the cystic duct from the gallbladder to the duodenal papilla, because an endoscopic method failed in the treatment of Lemmel syndrome. Because we were unable to place endoscopic transpapillary gallbladder drainage, percutaneous transhepatic gallbladder drainage (PTGBD) was performed and both the cholecystitis and cholangitis ceased. PTGS was performed as an alternative to endoscopic gallbladder stenting. Access to the cystic duct and gallbladder was obtained by the PTGBD route, using a guidewire (0.035‐inch diameter) and seeking catheter (6.5 Fr) under fluoroscopic control. A 7‐Fr 12‐cm double‐pigtail biliary polyethylene stent was placed. The patient remained asymptomatic for 3 months after the PTGS until he died, of an acute recurrent myocardial infarction. This new PTGS placement is an alternative treatment for symptomatic gallbladder disease in patients with increased operative risk when the endoscopic method is unsuccessful. 相似文献

Vascular remodeling and plaque composition between focal and diffuse coronary lesions assessed by intravascular ultrasound 总被引:4,自引:0,他引:4
Fujii K Mintz GS Kobayashi Y Carlier SG Takebayashi H Jacoboff D Yasuda T Moussa I Dangas G Mehran R Lansky AJ Reyes A Kreps E Collins M Stone GW Leon MB Moses JW 《The American journal of cardiology》2004,94(8):1067-1070
Coronary remodeling and plaque composition were compared between focal and diffuse coronary lesions. Negative remodeling and fibrous and calcified plaque compositions contribute to stenosis development in diffuse lesions more frequently than in focal lesions. 相似文献

Clinical utility and approach to estimate postprandial hypertriglycemia by a newly designed oral fat-loading test 总被引:2,自引:0,他引:2
Igarashi M Hirata A Yamauchi T Yamaguchi H Tsuchiya H Ohnuma H Jimbu Y Okuyama Y Shirata T Otsu N Fukuyama H Takahashi S Tominaga M Kato T 《Journal of atherosclerosis and thrombosis》2003,10(5):314-320
The objective of this study was to estimate postprandial hypertriglycemia by a newly designed oral fat-loading test. Twenty-three healthy normolipidemic volunteers were orally administered a test meal consisting of a mixture of Telmeal 2.0 and 20 g of salt-free butter after fasting for 12 h. To measure the levels of total cholesterol (T-Cho), triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), remnant-like particle-cholesterol (RLP-C), lipoprotein (a) [Lp (a)], free fatty acid, apolipoproteins (Apos), plasma glucose (PG), immunoreactive insulin (IRI), and high-sensitivity C-reactive protein (hs-CRP), venous blood samples were collected before the meal and at each hour until 9 h after fat-loading. The levels of both TG and RLP-C were drastically elevated at 2 h after fat-loading and these levels remained high until 4 h (p < 0.01). A significant correlation between TG and RLP-C was also observed at 2, 3 and 4 h, and the values of the correlation coefficients (r) were 0.837, 0.838, and 0.908, respectively. In contrast, the levels of T-Cho, HDL-C, Lp (a), Apos, PG, and hs-CRP did not change. Furthermore, there were no gastrointestinal symptoms during or after the study. These results strongly suggested that this newly designed fat-loading test was very useful for evaluating postprandial hypertriglycemia, including remnant concentrations. 相似文献

Plasma interleukin-6 is associated with coagulation in poorly controlled patients with Type 2 diabetes. 总被引:2,自引:0,他引:2

AIMS: We investigated the relationship between interleukin (IL)-6 and coagulation, i.e. whether changes in the plasma IL-6 are associated with those in coagulation markers (D dimer and fibrinogen) after glycaemic control with sulphonylurea or insulin in poorly controlled patients with Type 2 diabetes. METHODS: We studied 42 patients with Type 2 diabetes, including 19 subsequently treated with sulphonylurea, 23 treated with insulin and 48 control subjects. All patients were in poor glycaemic control and were hospitalized for 3 weeks. At the beginning and end of treatment, we measured plasma concentrations of IL-6, fibrinogen, and D dimer. RESULTS: Plasma concentrations of IL-6 and D dimer were significantly higher in diabetic patients than in controls (P<0.0001 for both). In all patients with diabetes, the plasma concentration of IL-6 decreased significantly (P<0.001) after treatment. Changes in the plasma IL-6 during hospitalization were positively correlated with those in plasma D dimer and fibrinogen (r=0.664, P<0.0001; r=0.472, P=0.0042, respectively). Treatment with sulphonylurea or insulin caused a similar fall in the plasma IL-6 concentration with a concomitant decrease in the BMI and an equal improvement in glycaemia. CONCLUSIONS: In poorly controlled patients with Type 2 diabetes, plasma IL-6 concentrations were reduced significantly even by short-term metabolic control. As changes in the plasma concentrations of D dimer are related to plasma IL-6, plasma IL-6 may reflect a pro-coagulant as well as an inflammatory state in patients with Type 2 diabetes. 相似文献

OBJECTIVE: To investigate the involvement of osteopontin (OPN) in bone destruction in a murine experimental arthritis model of collagen-induced arthritis (CIA). METHODS: The expression of OPN was examined at both the messenger RNA (mRNA) and protein levels in various arthritic lesions in mice with CIA by in situ hybridization and immunohistochemistry, respectively. In addition, the expression of alpha(v)beta3 integrin, a receptor for OPN, the ligation of which is thought to be essential for bone resorption by osteoclasts, was examined by immunohistochemistry. Plasma concentrations of OPN were measured at different time points in the course of CIA by enzyme-linked immunosorbent assay. RESULTS: OPN mRNA was detected mainly at sites of bone erosion in arthritic lesions, where activated osteoclasts were present; OPN protein was also detected at sites of bone erosion. In the arthritic synovium, OPN was predominantly expressed in the synovial lining layer, but not in lymphoid aggregates. In addition, alpha(v)beta3 integrin was detected coincident with OPN at sites of bone erosion (bone-pannus junction). Plasma OPN levels were markedly elevated at the time points that corresponded to arthritis flares, and higher levels were maintained during the progression of arthritis. CONCLUSION: OPN may mediate bone resorption by osteoclasts in arthritis through ligation with its receptor, alpha(v)beta3 integrin. OPN may be a useful therapeutic target molecule in the prevention of bone destruction in arthritis. 相似文献

AIM: The aim of this study was to evaluate the anti-atherogenic outcomes of pioglitazone, a thiazolidinedione derivative, in type 2 diabetic patients. METHODS: Eight patients with poor diabetic control were treated with 15 mg of pioglitazone for 4 months. Blood samples were collected monthly, and the levels of fasting plasma glucose (FPG), HbA1c, and lipids, such as triglycerides, total cholesterol, low-density lipoprotein-cholesterol, and high-density lipoprotein-cholesterol, were measured. Other parameters, including immunorecative insulin (IRI), remnant-like particle-cholesterol (RLP-C), adiponectin, plasminogen activator inhibitor type 1 (PAI-1), tumor necrosis factor (TNF)- alpha , leptin, brain natriuretic peptide (BNP), and high-sensitivity (hs)-C-reactive protein (CRP), were examined at the beginning and end of the study. In addition, clinically adverse side-effects were evaluated. RESULTS: Treatment with pioglitazone significantly decreased the levels of HbA1c, FPG, the homeostasis model assessment of insulin resistance (HOMA-IR) index, RLP-C, PAI-1, TNF- alpha , and hs-CRP, but not the level, IRI, lipids, or leptin. In contrast, adverse side-effects, including body weight gain, liver dysfunction and edema, were not observed during this study. CONCLUSION: These results strongly suggested that treatment with pioglitazone has a greater clinical benefit for the prevention of atherosclerosis, including coronary heart diseases, without any adverse side-effects. 相似文献
