The aim of this study was to evaluate the risk of depression in and effect of l-thyroxine therapy on patients with Hashimoto thyroiditis (HT) in Taiwan.In this retrospective, nationwide cohort study, we retrieved data from the Longitudinal Health Insurance Database 2000. We collected data of 1220 patients with HT and 4880 patients without HT for the period 2000 to 2011. The mean follow-up period for the HT cohort was 5.77 years. Univariate and multivariate Cox proportional hazards regression models were used to estimate the risk of depression in the HT cohort.In the HT cohort, 89.6% of the patients were women. Compared with the non-HT cohort, the HT cohort exhibited a higher prevalence of diabetes mellitus, hyperlipidemia, and coronary artery disease. Furthermore, the HT cohort showed a higher overall incidence of depression compared with the non-HT cohort (8.67 and 5.49 per 1000 person-year; crude hazard ratio [HR] = 1.58, 95% confidence interval [CI] = 1.18–2.13). The risk of depression decreased after administration of l-thyroxine treatment for more than 1 year (adjusted HR = 1.02; 95% CI = 0.66–1.59).In Taiwan, the overall incidence of depression was greater in the young HT cohort. l-thyroxine treatment reduced the risk of depression. 相似文献

Safrole, a naturally occurring product derived from spices and herbs, has been shown to be associated with the development of hepatocellular carcinoma in rodents. Safrole 2',3'-oxide (SFO), an electrophilic metabolite of safrole, was shown to react with DNA bases to form detectable DNA adducts in vitro, but not detected in vivo. Therefore, the objective of this study was to investigate the formation of N7-(3-benzo[1,3]dioxol-5-yl-2-hydroxypropyl)guanine (N7γ-SFO-Gua) resulting from the reaction of SFO with the most nucleophilic site of guanine in vitro and in vivo with a newly developed isotope-dilution high performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS) method. N7γ-SFO-Gua and [(15)N(5)]-N7-(3-benzo[1,3]dioxol-5-yl-2-hydroxypropyl)guanine ([(15)N(5)]-N7γ-SFO-Gua) were first synthesized, purified, and characterized. The HPLC-ESI-MS/MS method was developed to measure N7γ-SFO-Gua in calf thymus DNA treated with 60μmol of SFO for 72h and in urine samples of mice treated with a single dose of SFO (30mg/kg body weight, intraperitoneally). In calf thymus DNA, the level of N7γ-SFO-Gua was 2670 adducts per 10(6)nucleotides. In urine of SFO-treated mice, the levels of N7γ-SFO-Gua were 1.02±0.14ng/mg creatinine (n=4) on day 1, 0.73±0.68ng/mg creatinine (n=4) on day 2, and below the limit of quantitation on day 3. These results suggest that SFO can cause in vivo formation of N7γ-SFO-Gua, which may then be rapidly depurinated from the DNA backbone and excreted through urine. 相似文献

AbstractThe 41-item Comprehensive Needs Assessment Tool for Cancer Caregivers (CNAT-C) is an English language survey for needs assessment developed and validated in South Korean cancer caregivers. The objective of this study was to validate both the English and a translated Chinese version of the CNAT-C in cancer caregivers in Singapore.This was a cross-sectional survey where cancer caregivers completed the CNAT-C and World Health Organisation Quality-of-life BREF (WHOQOL-BREF) in English or Chinese. Cronbach’s alpha was used to measure internal consistency. Convergent validity was assessed using Pearson correlation coefficients between CNAT-C scores and WHOQOL-BREF domains. For known groups validity, independent samples t-test was used to compare CNAT-C scores based on Karnofsky performance status.There were 161 cancer caregivers – 80 answered the English version and 81 answered the Chinese version. For the English version, 33.8% were male and the mean age was 46.9 years. For the Chinese version, 27.2% were male and the mean age was 52.6 years. The total CNAT-C score and most domain scores showed good internal consistency, low to moderate convergent validity with WHOQOL-BREF domains and good known groups validity with performance status in both the English and Chinese versions. Domain 1 (health and psychological problems) in the Chinese version did not show convergent validity although there was evidence of known groups validity. Domain 5 (religious/spiritual support) also did not show validity in our study sample.In summary, there was low to moderate convergent validity with the WHOQOL-BREF for both the English and translated Chinese versions. However, both language versions of CNAT-C showed good internal consistency and good known groups validity according to performance status, and both language versions of the CNAT-C can be used to assess the level of unmet needs for cancer caregivers in the Singapore context. 相似文献

Oxidative stress and apoptosis are 2 major characteristics of the progression of atherosclerosis. Both lovastatin and Magnolia officinalis are hypocholesterolemic agents. Therefore, we investigated the effect of M. officinalis extract on the prevention of atherosclerosis in comparison with lovastatin. Twenty hyperlipidemic rabbits were served one of the following diets: a high-fat and cholesterol diet (cholesterol group, 10% corn oil and 0.5% cholesterol), a high fat and cholesterol diet supplemented with M. officinalis extract (300 mg/kg) or lovastatin (6 mg/kg). The plasma lipids, oxidative stress (measured by free radical, malondialdehyde, and oxidative DNA damage), and arterial lesions significantly decreased in the M. officinalis and lovastatin groups when compared with the cholesterol group. Moreover, the expressions of Fas ligand, caspase 8, and caspase 9 in the aortic arches were also markedly lowered after M. officinalis and lovastatin supplements. Therefore, the results indicate that the antiatherogenic effect of M. officinalis is involved with a suppression of oxidative stress and with the down-regulation of apoptosis-related gene expression in hyperlipidemic rabbits. 相似文献
