A phase II study of mitoxantrone was performed in 24 patientswith non-small cell lung cancer (NSCLC). Mitoxantrone was administeredby intravenous drip infusion of 12 mg/m2 every three weeks.There were no responders among the 21 evaluable patients includingfive patients without prior therapy. The major hematologicaltoxic effect was leukocytopenia. Thrombocytopenia and decreasein hemoglobin were slight. A change in the electrocardiogramwas observed in one patient and one patient experienced cardiogenicshock. Mitoxantrone is not acceptable for the treatment of NSCLC becauseof its low antitumor activity, and careful observation is neededfor administration of this agent to patients with pre-existingrisk factors, such as prior anthracycline exposure, mediastinalradiation or underlying cardiovascular disease. 相似文献

Background: Endoscopic mucosal resection (EMR) is widely accepted as a minimally invasive treatment for early gastric cancer (EGC) in Japan. However, the criteria for EMR must be strictly adhered to otherwise patients will miss the chance for additional therapy. We assess the important factor in expanding the indication of EMR. Methods: We investigated 1101 EGCs that had been resected by EMR at the National Cancer Center Hospital (NCCH), Tokyo, Japan, according to the indication recommended by Japanese Gastric Cancer Association (JGCA) and the expanded indication proposed by NCCH. Curability and local recurrence of the EMRs were assessed related to the applied indication and the number of resected specimens. Results: The recurrence rate of non‐evaluable resection was higher than that of evaluable resection (P < 0.0001). Eighty‐three lesions among 772 lesions in the JGCA group were non‐evaluable. Thirty‐seven leisons among 329 lesions in the NCCH group were non‐evaluable. There was no difference in the rate of non‐evaluable resection between JGCA and NCCH groups (P = 0.8329). However, the rate of curative resection was lower in the NCCH group than in the JGCA group (P = 0.0009). In piecemeal resection, there was no difference in the rate of non‐evaluable resection between JGCA and NCCH groups (P = 0.0527). In one‐piece resection, the rate of non‐evaluable resection was lower in the NCCH group than the JGCA group (P = 0.0137). Conclusion: Based on our series of cases, we propose one‐piece resection as a gold standard for EMR because it enables accurate histological evaluation, even in the EMR, according to the expanded indication. 相似文献

Meconium aspiration syndrome (MAS) is a frequent cause of respiratory distress in neonates. Recent reports have suggested that surfactant dysfunction contributes to the pathophysiology of MAS and surfactant therapy improves oxygenation of infants with MAS. We evaluated the effect of bronchial lavage with surfactant solution in a rabbit model of meconium aspiration. All animals were given 5 mL/kg of a 20% slurry of human meconium into the endotracheal tube and mechanically ventilated. The animals were then divided into saline lavage (n = 5) or surfactant lavage (n = 5). Lavage was performed an hour after meconium instillation. After the lavage the total amount of meconium recovered was measured. Blood gas was monitored during the experiment. The amount of meconium recovered by saline lavage was 14%, and by surfactant lavage was 57%. The surfactant group had a significant improvement in gas exchange, whereas the saline group had no improvement. It was concluded that the lavage with surfactant solution effectively washed out meconium and improved gas exchange in rabbit model of MAS. 相似文献

A high-performance liquid chromatographic (HPLC) assay was developed for the determination of trazodone and its metabolite, 1-m-chlorophenylpiperazine (m-CPP), in plasma. The high level of trazodone in plasma was detected by ultraviolet absorbance at 254 nm and the low level of m-CPP in plasma was detected by coulometric electrochemical detection at 840 mV on the series arrangement of two detectors. Pilsicainide as an internal standard for both compounds was monitored by both detectors. Trazodone and m-CPP in plasma were extracted by a rapid and simple procedure based on CN bonded-phase extraction, and C8 reversed-phase HPLC separation. Determination was possible for trazodone in the concentration range 100–2000 ng mL?1 and for m-CPP in the concentration range 5–100 ng mL?1. The recoveries of trazodone and m-CPP added to plasma were 81·0–84·2 and 68·0–73·2%, respectively, with coefficients of variation of less than 7·3 and 8·2%, respectively. The method is applicable to high level monitoring of trazodone and low level monitoring of m-CPP in plasma of healthy volunteers and patients treated with trazodone. 相似文献

Modulation of Fas-mediated apoptosis of human thyroid epithelial cells by IgG from patients with Graves' disease (GD) and idiopathic myxoedema 总被引:3,自引:0,他引:3 下载免费PDF全文

The expression of two autoimmune thyroid diseases, GD and idiopathic myxoedema, is associated with antibodies to the thyroid-stimulating hormone (TSH) receptor. Thyroid stimulating antibodies (TSAb) in GD are TSH agonists and cause hyperthyroidism as well as goitre, whereas thyroid stimulation blocking antibodies (TSBAb) in idiopathic myxoedema are TSH antagonists and cause hypothyroidism and thyroid atrophy. We investigated the effect of antibodies to TSH receptor on Fas-mediated apoptosis of thyroid epithelial cells (thyrocytes). Human IgG was isolated from healthy donors, patients with GD and idiopathic myxoedema. Human thyrocytes were obtained from surgical specimens. Thyrocytes were cultured in the presence or absence of human IgG with or without interferon-gamma (IFN-γ) or IL-1β for a specified time. After incubation, we examined the level of cAMP in cultured supernatants and both Fas and Bcl-2 expression on thyrocytes. In addition, we examined anti-Fas-mediated apoptosis of thyrocytes. Fas expression on thyrocytes was significantly down-regulated by Graves' IgG and TSH, although idiopathic myxoedema IgG did not affect Fas expression on thyrocytes. Idiopathic myxoedema IgG abrogated the effect of TSH on both cAMP production and inhibition of Fas expression on thyrocytes. Treatment of thyrocytes with IL-1β or IFN-γ caused a marked augmentation of Fas expression on thyrocytes. The increase of Fas expression of thyrocytes induced by IL-1β or IFN-γ was significantly suppressed in the presence of TSH or Graves' IgG. Anti-Fas-induced apoptosis of thyrocytes was observed in thyrocytes treated with IL-1β or IFN-γ, but was markedly inhibited in the presence of TSH or Graves' IgG. Furthermore, idiopathic myxoedema IgG abrogated most of the inhibitory effect of TSH on Fas-mediated apoptosis of thyrocytes treated with IL-1β or IFN-γ. Bcl-2 expression of thyrocytes did not change after stimulation with TSH, Graves' IgG, idiopathic myxoedema IgG, IL-1β or IFN-γ. These results suggest that TSAb found in Graves' patients may be potentially involved in the development of goitre by inhibition of Fas-mediated apoptosis of thyrocytes. In addition, TSBAb inhibit the action of TSH and increase the sensitivity toward Fas-mediated apoptosis of thyrocytes, inducing thyroid atrophy seen in patients with idiopathic myxoedema. 相似文献

Forty-eight cases of surgically resected benign tumors and tumor-likelesions of the lung were analyzed, with the following results:1) Hamartoma and sclerosing hemangioma have well defined borders,compressing bronchi and blood vessels, and are loosely boundto the surrounding lung parenchyma. 2) Hamartomas, in 90% ofthe cases, showed "nodularity" on film tomograms. Histologically,nodularity at the edge was produced by lobules of cartilage.3) Fifty-three percent of the patients with sclerosing hemangiomawere middle-aged females and asymptomatic. Only two patientscomplained of hemosputum. Routine roentgenograms showed a roundshadow with homogeneous density. Cut surfaces were solid withvarious degrees of hasemorrhage. 4) Roentgenograms of benignmesothelioma showed large tumors more than 4 cm in diameter,in which extrapleural signs could be observed. 5) "Calcification"was seen on the roentgenograms of seven out of 27 hamartomasand one out of 15 sclerosing hemangiomas. Pleural retractioncould not be seen in our series. Xerotomography was superiorto film tomography in showing calcification. 6) One of the sclerosinghemangiomas was double, and the other 47 benign tumors and tumor-likelesions were solitary; the lesions were peripheral in 45 casesand central in three. All of the patients were free of localrecurrence and distant metastasis. 相似文献

We report on a 3 year old girl with acute promyelocytic leukemia (APL) with cerebral infarction due to disseminated intravascular coagulation (DIC) at initial presentation. She was hospitalized because of unconsciousness and petechiae on the chest wall and extremities. Cerebral ischemia and infarction were found on computed tomography scan and magnetic resonance imaging. Peripheral bood content was hemoglobin 7.3 g/dL, white blood cells 1.0 × 103cells/μL (31% blasts) and platelet count was 12 × 103cells/μL. Fragmented erythrocytes were frequently observed on May-Giemsa stained blood smears. Bone marrow aspirates showed normal cellularity, with 60.4% blasts, containing faggot cells. The blasts were positive for peroxidase. Therapy was begun; however, the patient died 1 week after admission. 相似文献

High-dose ifosfamide (one or two courses of 6 g/m2) with orwithout mesna was administered to 13 patients with advancednon-small cell lung cancer. The protective effect of 2-mercapto-ethanesulfonate (mesna) against the urotoxic side effects inducedby ifosfamide was examined by a randomized crossover trial.A significant reduction in the incidence of hematuria was observedin the patients receiving mesna. Macroscopic hematuria was observedin only one patient who received treatment with mesna versusseven patients treated with ifosfamide alone. Other symptoms,such as frequency and dysuria, tended to be diminished in thepatients receiving mesna, although the difference was not statisticallysignificant. Our results suggest that mesna is effective inpreventing or diminishing ifosfamide-induced hemorrhagic cystitis.Concomitant use of mesna should allow the administration ofa high dose of ifosfamide although more extensive studies areneeded to define the optimal dose and schedule of administrationof mesna to prevent or attenuate the hemorrhagic cystitis. 相似文献

In device-aided therapy (DAT) for Parkinson’s disease (PD), factors such as device-related adverse effects, psychological and lifestyle changes, and specific disease progression can affect the quality of life (QoL) of patients with advanced PD. However, there is no existing QoL scale that includes the effects of therapeutic devices. From a semi-structured interview with patients with PD undergoing deep brain stimulation (DBS), we extracted the content of utterances that were thought to affect the QoL and created a draft questionnaire consisting of 113 items. This questionnaire was administered to 54 other patients undergoing DBS, whose data were examined for reliability and validity by factor analysis, and finally, a 24-item PD QoL questionnaire for patients on DAT (PDQ-DAT) was developed. Presently, the PDQ-DAT is the only scale that can assess the QoL of patients on DAT, including the influence treatment devices have on them. In the future, it might be used to help in shared decision-making in medicine by incorporating the patient’s sense of burden and values in the selection of treatment methods. 相似文献

We report a case of mucinous adenocarcinoma of the renal pelvis associated with bladder carcinoma in situ (CIS). Transitional cell carcinoma (TCC) of the renal pelvis and CIS were also observed adjacent to the adenocarcinoma. Immunohistochemical assessment of the pelvic adenocarcinoma revealed positive expressions for mucin, epithelial membrane antigen, cytokeratin 7, cytokeratin 19 and carcinoembryonal antigen, but not vimentin or chromogranin. Based on the histopathological examinations, the adenocarcinoma of the renal pelvis in the present case may have a similar biological nature to conventional TCC and probably originated by development of pre-existing TCC of the renal pelvis. 相似文献
