Low-dose aspirin, one of non-steroidal anti-inflammatory drugs(NSAIDs), has been increasingly used to prevent cardiovascular and cerebrovascular disease through its antiplatelet effect, mainly in the aged population, but aspirin treatment has been associated with gastrointestinal injures, especially peptic ulcer bleedings. However, as discontinuation of aspirin, unlike NSAIDs, may precipitate cardiovascular and cerebrovascular events, treatment of aspirin-associated ulcers should re-start aspirin as soon as possible, using proton pump inhibitor (PPI). Therefore, high risk patients for peptic ulcers should be prevented with antisecretory drugs, such as PPI or histamine H2-receptor antagonists, because ulcer bleedings in patients with treatment of low-dose aspirin can be serious. 相似文献

Most fetal goitrous hypothyroidisms are reportedly caused by the maternal use of an antithyroid drug or fetal dyshormonogenesis. However, fetal goitrous hypothyroidism due to the transplacental passage of maternal thyroid stimulation-blocking antibody (TSBAb) is extremely rare. A woman at 28 weeks of gestation was found to have a fetal goiter by ultrasonography. Because the maternal serum showed hypothyroidism with an elevated titer of TSBAb, levothyroxine sodium was administered. The patient delivered a male infant, 3,412 g, with a goiter at term. Umbilical blood revealed primary hypothyroidism with increased TSBAb, and the infant was given levothyroxine sodium. After a month, neonatal thyroid function and TSBAb levels became normal. Attention should be paid to possible fetal hypothyroidism when a fetal goiter is observed to avoid impaired mental development of the neonate. 相似文献

PURPOSE: We determined whether inhibitor of caspase-3 activated deoxyribonuclease (ICAD) enhances resistance to apoptotic stimuli or inhibits DNA fragmentation by inactivating caspase-3 activated deoxyribonuclease. MATERIALS AND METHODS: The liposome mediated gene transfer method was used to introduce ICAD complementary DNA into ACHN cells and the expression of ICAD protein per clone was evaluated by Western blot analysis. Effects of cisplatin treatment on growth inhibition and apoptosis in the ACHN sublines were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, DNA fragmentation assay and Western blot analysis of poly(ADP-ribose) polymerase protein. The limiting dilution assay was also performed to examine the effect of cisplatin treatment under anchorage independent conditions. Furthermore, nude mice bearing the ACHN sublines were given intraperitoneal injection of 5 mg./kg. cisplatin 1 and 2 weeks after the implantation of tumor cells and changes in tumor volume was measured. RESULTS: ICAD transfected ACHN cells inhibited DNA degradation after cisplatin treatment but not control vector only transfected ACHN cells, whereas a similar degree of apoptotic cell death induced by cisplatin in ICAD and control vector only transfected ACHN cells was observed on 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and Western blot analysis of poly(ADP-ribose) polymerase protein. However, the limiting dilution assay revealed that ICAD transfected ACHN cells had high resistance to pretreatment with cisplatin compared with control vector only transfected ACHN cells. Moreover, although there was no significant difference in the in vivo growth of ACHN sublines, cisplatin treatment induced the elimination of control vector only transfected ACHN cell tumors. In contrast, most ICAD transfected ACHN cell tumors continued to grow after cisplatin treatment. CONCLUSIONS: These findings suggest that when ICAD is over expressed in tumor cells, it renders them highly resistant to therapy induced apoptosis, resulting in enhanced tumor progression. 相似文献

Correction of hyperglycaemia reduces insulin resistance and serum soluble E-selectin levels in patients with Type 2 diabetes mellitus. 总被引:2,自引:0,他引:2
AIMS: To investigate the effects of glycaemic control on insulin sensitivity and serum concentrations of soluble vascular cell adhesion molecule (sVCAM)-1 and E-selectin (sE-selectin) in patients with Type 2 diabetes mellitus. To examine whether reductions in serum adhesion molecule levels correlate with improvement in insulin resistance. METHODS: A total of 54 patients with Type 2 diabetes were treated for 4 weeks with either diet alone, sulphonylurea or insulin. Fasting glucose, insulin sensitivity, lipids, sVCAM-1, and sE-selectin levels were measured before and after treatment. RESULTS: All treatment modalities successfully corrected hyperglycemia. Reductions in blood glucose levels resulted in improvement in insulin sensitivity (diet KITT 2.40 +/- 0.26-3.09 +/- 0.36, P < 0.01; sulphonylurea 2.24 +/- 0.16-2.94 +/- 0.18, P < 0.01; insulin 1.68 +/- 0.27-2.16 +/- 0.22%/min, P < 0.05), and decrease in sE-selectin levels (diet 88.4 +/- 14.9-66.2 +/- 10.8, P < 0.05; sulphonylurea 85.1 +/- 11.6-59.8 +/- 7.8, P < 0.01; insulin 84.4 +/- 8.7-66.8 +/- 7.4 ng/ml, P < 0.01), but no change in sVCAM-1 levels. There was a significant correlation between the degree of decrease in sE-selectin levels and improvement in insulin sensitivity (r = -0.38, P < 0.01). CONCLUSIONS: Correction of hyperglycaemia, independent of treatment modality, resulted in improvement of insulin resistance and decrease in sE-selectin levels. These changes might, in part, contribute to reduce the risk of diabetic microvascular and macrovascular complications in patients with Type 2 diabetes mellitus. 相似文献

SUMMARY: This is a retrospective study of long-term radiographic results for congenital subluxation of the hip (CSH) after closed reduction at the authors' hospital from 1963 to 1980. The age at final follow-up ranged from 14.0 to 33.9 years (average 19.1). The diagnosis of CSH was determined radiographically using Ishida criteria. The center-edge angle (CE angle) and the Sharp angle were measured serially, and the final results were evaluated using Severin classification, and evaluation of avascular necrosis used the classification of Kalamchi and MacEwen. Sixty-nine (26.3%) of 262 hips with CSH were rated as Severin group III or IV. Avascular necrosis was found in 12 hips (4.6%). The CE angle of unaffected hips had strong correlation with that of affected hips. These late results were not satisfactory and indicate that patients with CSH should be followed up at least until skeletal maturity, as is done with complete hip dislocation. 相似文献

A case of Churg-Strauss syndrome in which positive rheumatoid factor and MPO-ANCA preceded the development of clinical symptoms of vasculitis] 总被引:1,自引:0,他引:1

A 52-year-old man in whom bronchial asthma had been diagnosed in 1995 was admitted for the treatment of Churg-Strauss syndrome in June 1997. Positive tests MPO-ANCA and rheumatoid factor preceded the symptoms of vasculitis for several months. A skin biopsy revealed infiltration of eosinophils in the vessel walls, and the diagnosis of Churg-Strauss syndrome was confirmed. After systemic administration of corticosteroids, the symptoms other than mononeuritis improved markedly, and his MPO-ANCA and rheumatoid factor became negative. Rheumatoid factor and MPO-ANCA may be useful for the early diagnosis of Churg-Strauss syndrome in patients with bronchial asthma in which a well-controlled disease develops into an intractable condition. 相似文献

BACKGROUND: Although lasers and intense pulsed light sources have improved the capability of injuring veins without affecting the overlying skin, work is needed to improve the procedure. OBJECTIVE: To create a method for predicting skin reaction to pulsed light. METHODS: Twenty patients were divided into four groups according to skin type (I-IV). An industrial thermometer equipped with a laser-aiming system was adapted to the intense pulsed light source handpiece. Patients received shots of increasing intensity while the skin temperature was measured. RESULTS: Fluence and temperature data were analyzed by logistic regression to evaluate possible injury. The stepwise method selected skin type and temperature variation as predictors of skin injury. Logistic curves indicated the maximum temperature variation tolerable for each skin type. More pigmented skin types tolerated less temperature increase. CONCLUSION: Skin type can predict cutaneous reaction to intense pulsed light through measurements of temperature variation. This method may help achieve successful selective photothermolysis. 相似文献

OBJECTIVE: To determine whether serum levels of the prostate-specific antigen-alpha1-antichymotrypsin complex (PSA-ACT) and its density (ACTD) in patients scheduled to undergo radical prostatectomy for clinically localized prostate cancer can predict organ-confined vs extraprostatic disease. PATIENTS AND METHODS: Serum samples were obtained from 62 patients with clinically localized prostate cancer before they underwent radical prostatectomy. PSA and PSA-ACT were measured using immunofluorometric techniques with different monoclonal antibodies against PSA and ACT, respectively. Furthermore, the PSA and PSA-ACT densities of the whole prostate (PSAD and ACTD, respectively) were calculated. The relationships of serum PSA, PSA-ACT, PSAD, ACTD and the pathological stage of the prostatectomy specimens were analysed. RESULTS: The disease was organ-confined or extraprostatic in 30 and 32 men, respectively. In men with organ-confined cancer, the mean PSA and PSA-ACT levels were significantly lower than in those with extraprostatic disease. Furthermore, there were significantly higher mean PSAD and ACTD levels in men with extraprostatic than with organ-confined disease. There were also significant differences in PSA, PSA-ACT, PSAD and ACTD levels at each pathological stage, whereas there was no significant association between these variables and the Gleason score. Receiver-operating characteristic curve analysis for detecting organ-confined disease showed that PSA-ACT and ACTD had a larger area under the curve than PSA and PSAD, respectively, but these differences were not significant. Furthermore, PSA-ACT and ACTD provided significantly better sensitivity for detecting organ-confined disease than PSA and PSAD, respectively. CONCLUSIONS: Measuring PSA-ACT and ACTD may improve the preoperative evaluation of patients scheduled to undergo radical prostatectomy, because these factors better differentiate extraprostatic from organ-confined disease than PSA and PSAD. 相似文献
