嚼槟榔让女性面临心脏病的危险。中国台湾的一项人群研究发现,男性嚼槟榔的比例高于女性(分别为31%和2.4%),但心脏病患病率在两者间无显著差异(American Journal of Clinical Nutrition 2007;85:1229-35,www.ajcn.org)。每日嚼槟榔的次数与心脏病的患病率独立相关;女性每13嚼10个槟榔的关联比值比为1.37(95%CI1.1~1.6,P=0.003)。  相似文献

AIM: Single nucleotide polymorphisms (SNPs) of uridinediphosphoglucuro -nosyltransferase 1A7 (UGT1A7) gene are associated with the development of orolaryngeal cancer, hepatocellular carcinoma, and colorectal cancer. We performed this research to establish the techniques for determining UGT1A7 gene and basic data of this gene for Taiwan Chinese. METHODS: We collected blood samples from 112 healthy adults and 505 subjects carrying different genotypes of UGT1A1, and determined the promoter area and the entire sequence of UGT1A7 exon 1 by polymerase chain reaction. We designed appropriate primers and restriction enzymes to detect variant UGT1A7 genotypes found in the study subjects. RESULTS: Six SNPs at nucleotides 33, 387, 391, 392, 622, and 756 within the coding region of UGT1A7 exon 1 were found. The incidence of UGT1A7*l/*2 (N129R131W208/ K129K131W208) was predominant (35.7%) while that of UGT1A7 *3/*3 (K129K131R208/K129K131R208) was the least (2.7%). The allele frequency of UGT1A7*3, which exists in a considerable proportion of Caucasians (0.361) and Japanese (0.255), was identified only to be 0.152 in our study subjects. A novel variation at nucleotide -57 in the upstream was found, which was associated with SNPs at nucleotides 33, 387, 391, 392, and 622 in one of the variant haplotypes. The nucleotide changes at positions 387, 391, 392 and 756 were in linkage in another variant haplotype. The allele frequency of UGT1A7*3 was 0.018, 0.158, 0.242, 0.433, and 0.920 in subjects carrying wild, A(TA)6TAA/A(TA)7TAA, A(TA)7TAA/A(TA)7TAA, 211G/211A, and 211A/211A variants of UGT1A1 gene, respectively. By using natural or mutagenesis primers, we successfully detected the variations at nucleotides -57, 33, 387, and 622 with the restriction enzymes HpyCH4 Ⅳ, TaqⅠ, AflⅡ, and Rsa Ⅰ, respectively. CONCLUSION: The results indicate that the allele frequencies of UGT1A7 gene in Taiwan Chinese are different from those in Caucasians and Japanese. Carriage of the nucleotide 211- variant UGT1A gene is highly associated with UGT1A7*3. The restriction-enzymedigestion method for the determination of nucleotides-57 (or 33, or 622) and 387 can rapidly identify genotypes of UGT1A7 in an individual.  相似文献

AIM: To examine whether peanut consumption is associated with a reduced risk of colorectal cancer in a prospective cohort with a 10-year follow-up. METHODS: In 1990-1992, residents (12026 men and 11917 women aged 30 to 65 years) in 7 townships, Taiwan, were interviewed and recruited into a cancer-screening cohort and annually followed up. Colorectal cancer cases in this cohort were identified from cancer registry and death certificates. Incidence rates of this disease by the end of 2001 were calculated by gender for the primary study variable and covariates. The dietary intake was assessed by means of weekly food frequency measures, including frequently consumed food groups and folk dishes including sweet potato, bean products, peanut products, pickled foodstuffs, nitrated or smoked foodstuffs. RESULTS: During the study period, 107 new colorectal cancer cases (68 men and 39 women) were confirmed. The multivariate Cox's proportional hazard model showed that the relative risk (RR) of peanut consumption was 0.73 [95% confidence interval (CI) =0.44-1.21] for men and 0.42 (95% CI =0.21-0.84) for women. However, frequent intake of pickled foodstuffs was harmful for women (RR = 2.15, 95% CI =0.99-4.65). The risk of colorectal cancer was also elevated among cigarette smokers but not significant (P<0.05). CONCLUSION: This study suggests that frequent intake of peanut and its products may reduce colorectal cancer risk in women, demonstrating the anti-proliferating effect of peanut intake.  相似文献

AIM:To elucidate the prognostic role and relationship ofthree molecular markers such as tumor suppressor genep53,proliferating cell nuclear antigen(PCNA)and Ki-67in gastric stromal tumor.METHODS:A total of 108 surgically resected gastricsmooth muscle tumor specimens were collected fromJanuary 1987 to December 1999.Immunohistochemicalstudies were performed on the paraffin sections of 99of 108 CD117-positive tumors with antibodies of p53,PCNA,and Ki-67.Immunoreactivity of three molecularmarkers was recorded by labeling index(LI,%)and wasanalyzed for clinicopathologic and survival correlation.RESULTS:Of the 99 cases,immunostaining revealedthat 52 patients(52.5%)had p53,and 37 patients(37.3%)had Ki-67 immunoreactivity(defined as>10%of LI).All patients(100%)had PCNA immunoreactivityranging from 12% to 93% of LI,divided into high orlow by median.Statistics revealed that LI of threemarkers positively correlate to each other(P<0.01)and to microscopic tumor mitotic counts(P<0.001).By combination,patients with≥2 markers(positiveor high)in tumors had early tumor recurrence(P<0.001)and unfavorable outcome(P<0.001).Univariate analysis indicated that patients with tumorsize>5 cm(P=0.003),tumor mitosis>5/50 HPF(P<0.001),p53 immunoreacUvity(P=0.001),Ki-67 immunoreactivity(P=0.026),high PCNA LI(P=0.015)and male gender(P=0.036)were six predictors for earlydisease recurrence.Subsequent multivariate analysisrevealed that mitotic counts,tumor size,and p53immunoreactivity were three independent prognosticfactors for both disease free and overall survival ofpatients.By combination of three independent prognosticfactors for grouping,we found higher tumor recurrencerate(P<0.001)and shorter survival(P<0.001)existed ingroups with increasing factors.CONCLUSION:We first provide the prognostic valueand linkage of three molecular markers in GISTs.Thecombination of three factors(p53,tumor size,andtumor mitosis)provides a more powerful prediction ofprognosis than any single factor does.  相似文献
