A patient with advanced and probably radioresistant cervical cancer underwent pelvic vascular bed isolation, and 60 mg of mitomycin C was given in a one-shot manner into the internal iliac arteries. Visual, cytological, and histological evidence of local malignancy and cytoscopic evidence of bladder invasion were all gone 2 weeks after the isolation. Macroscopic evidence of malignancy of the uterus and vagina surgically removed 3 weeks after the isolation also disappeared. However, a remnant of microscopic malignancy was found in a small area of one fragment of the cervix radially divided into eight sections. 相似文献

Influence of alcohol consumption and gene polymorphisms of ADH2 and ALDH2 on hepatocellular carcinoma in a Japanese population 总被引:2,自引:0,他引:2
Sakamoto T Hara M Higaki Y Ichiba M Horita M Mizuta T Eguchi Y Yasutake T Ozaki I Yamamoto K Onohara S Kawazoe S Shigematsu H Koizumi S Tanaka K 《International journal of cancer. Journal international du cancer》2006,118(6):1501-1507
Although alcohol intake as well as hepatitis viruses has been associated with hepatocellular carcinoma (HCC), gene-alcohol interactions on HCC risk remain to be elucidated. We conducted a case-control study to examine whether polymorphisms of alcohol dehydrogenase 2 (ADH2) and aldehyde dehydrogenase 2 (ALDH2) modified the HCC risk depending on the amount of alcohol intake. ADH2 and ALDH2 genotyping was performed by a duplex polymerase chain reaction with confronting two-pair primers in 209 newly diagnosed HCC cases and 2 different controls [275 hospital controls and 381 patients with chronic liver disease (CLD)]. Multiple logistic regression analyses revealed that heavy drinkers consuming >or=3 "go"s/day of sake (69 g of ethanol/day) showed an increased risk of HCC based on comparison of HCC cases with hospital controls [adjusted odds ratio (OR) = 13.5; 95% confidence interval (CI) 3.3-54.3] or CLD patients (adjusted OR = 7.0; 95% CI 2.5-19.2), whereas the overall risk was not elevated among light to moderate drinkers consuming <3 "go"s/day. Interestingly, light to moderate drinking was associated with an increased risk among those with ALDH2*1/*2 (adjusted OR = 4.5 or 2.0), but not among those with ALDH2*1/*1 (adjusted OR = 0.8 or 1.0; p interaction = 0.03 or 0.13). However, this gene-alcohol interaction was not observed for heavy drinking. Among light to moderate drinkers, people with the combination of ALDH2*1/*2 and ADH2*2/*2 revealed the highest risk of HCC. These findings indicate that the ALDH2 polymorphism may modify HCC risk among light to moderate drinkers. 相似文献

High-turnover osteoporosis is induced by cyclosporin A in rats 总被引:2,自引:0,他引:2
Wada C Kataoka M Seto H Hayashi N Kido J Shinohara Y Nagata T 《Journal of bone and mineral metabolism》2006,24(3):199-205
Cyclosporin A (CsA) is used widely as an immunosuppressive agent, but it induces osteoporosis as a prominent side effect.
To elucidate the mechanisms involved in CsA-induced osteoporosis, the effects of CsA on bone metabolism were investigated
in a rat experimental model. Fifteen-day-old rats were fed a powdered diet containing or lacking CsA for 8–30 days. Analysis
was performed by micro-computed tomography (μCT) and light microscopy to examine histomorphometric changes in rat tibiae on
days 8, 16, and 30. Plasma parathyroid hormone (PTH) and osteocalcin (OCN) levels were determined by enzyme-linked immunosorbent
assay (ELISA) on days 8, 16, and 30. The expression of OCN, osteopontin (OPN), and cathepsin K mRNAs in tibial bone marrow
was examined by Northern blot analysis on days 8 and 16. Although no significant differences were observed in tibial length
during the experimental periods, or in histomorphometric parameters on day 8, an apparent decrease in bone volume was observed
in the CsA-treated group after day 16. Histologic analysis showed that the number of osteoblasts and osteoclasts on the surface
of trabecular bone in the CsA-treated group had increased significantly on day 16. Plasma PTH and OCN levels in CsA-treated
rats were significantly higher than those in control animals on day 8. Northern blot analysis revealed that the CsA-treated
group showed an increase in the expression of OCN, OPN, and cathepsin K mRNAs on day 8 compared with the controls. These findings
suggest that bone resorption in CsA-treated rats is induced by high-turnover osteoporosis and that bone remodeling activity
may be activated by PTH. 相似文献

Risk factors contributing to hepatic artery thrombosis following living-donor liver transplantation 总被引:2,自引:0,他引:2
Ikegami T Hashikura Y Nakazawa Y Urata K Mita A Ohno Y Terada M Miyagawa S Kushima H Kondoh S 《Journal of Hepato-Biliary-Pancreatic Surgery》2006,13(2):105-109
Background/Purpose This study was carried out to investigate the risk factors contributing to hepatic artery thrombosis in living-donor liver
transplantation.
Methods Two hundred and twenty-two recipients (113 adults and 109 children) of living-donor liver transplantation were the subjects
of this study. The diagnosis of hepatic artery thrombosis was made by color-Doppler ultrasonography and/or hepatic angiography.
Parameters for this study were: (1) donor sex, age, and body weight; (2) recipient sex, age, body weight, liver disease, preoperative
prothrombin time, and type of arterial reconstruction; and (3) previous liver transplantation.
Results Hepatic artery thrombosis occurred in 12 patients (5.4%) at 3 to 15 days posttransplant. Recipient female sex and metabolic
disorder as the original disease were found to be significantly associated with hepatic artery thrombosis. The 5-year patient
survival rate in recipients with hepatic artery thrombosis (58.3%) was significantly lower than that in recipients without
this complication (84.4%).
Conclusions Female sex and metabolic disease may be factors contributing to hepatic artery thrombosis after living-donor liver transplantation.
More intensive anticoagulation therapy for this patient population might decrease the incidence of hepatic artery thrombosis
and, thus, posttransplant recipient mortality. 相似文献

JPN Guidelines for the management of acute pancreatitis: severity assessment of acute pancreatitis 总被引:7,自引:3,他引:4
Hirota M Takada T Kawarada Y Hirata K Mayumi T Yoshida M Sekimoto M Kimura Y Takeda K Isaji S Koizumi M Otsuki M Matsuno S;JPN 《Journal of Hepato-Biliary-Pancreatic Surgery》2006,13(1):33-41
This article addresses the criteria for severity assessment and the severity scoring system of the Ministry of Health and
Welfare of Japan; now the Japanese Ministry of Health, Labour, and Welfare (the JPN score). It also presents data comparing
the JPN score with the Acute Physiology and Chronic Health Evaluation (APACHE) II score and the Ranson score, which are the
major measuring scales used in the United States and Europe. The goal of investigating these scoring systems is the achievement
of earlier diagnosis and more appropriate and successful treatment of severe or moderate acute pancreatitis, which has a high
mortality rate. This article makes the following recommendations in terms of assessing the severity of acute pancreatitis:
(1) Severity assessment is indispensable to the selection of proper initial treatment in the management of acute pancreatitis
(Recommendation A).
(2) Assessment by a severity scoring system (JPN score, APACHE II score) is important for determining treatment policy and
identifying the need for transfer to a specialist unit (Recommendation A).
(3) C-reactive protein (CRP) is a useful indicator for assessing severity (Recommendation A).
(4) Contrast-enhanced computed tomography (CT) scanning and contrast-enhanced magnetic resonance imaging (MRI) play an important
role in severity assessment (Recommendation A).
(5) A JPN score of 2 or more (severe acute pancreatitis) has been established as the criterion for hospital transfer (Recommendation
A).
(6) It is preferable to transfer patients with severe acute pancreatitis to a specialist medical institution where they can
receive continuous monitoring and systemic management. 相似文献
