Green tea has already been linked to health benefits
人们总是把绿茶和有益健康联系在一起
A chemical found in green tea appears to slow the progression of prostate cancer, a study has suggested.
一项研究表明，在绿茶中发现的一种化学物质似乎能够减缓前列腺癌的发展。
Green tea has been linked to a positive effect on a wide range of conditions, including heart disease, cancer and Alzheimer's disease.
人们都认为绿茶对许多疾病有正面的治疗作用，其中包括心脏病、癌症和老年痴呆。
The research, in the US journal Cancer Prevention Research, found a significant fall in certain markers which indicate cancer development.
美国期刊《癌症预防研究》中有研究发现，反映癌症发展状况的指数急剧下降。
A UK charity said the tea might help men manage low-risk tumours.
英国一家慈善机构称，茶或许可以帮助人们对抗低风险肿瘤。
Although previous studies have shown benefits from drinking green tea - including some positive findings in relation to prostate cancer, there have been mixed results.
虽然之前的研究都显示喝绿茶有益—其中有一些是有关对抗前列腺癌的正面发现，但研究结果并不全都是正面发现。
In this study, Philadelphia-based researchers tested a compound called Polyphenon E.
在此研究中，基于费城的研究者测试了一种叫做茶多酚E的化合物。
They were looking for a number of biomarkers - molecules - including vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) which are indicators of developing cancer.
他们正在寻找一系列的生物标志—分子—其中包括血管内皮生长因子(VEGF)和肝细胞生长因子(HGF)，这些因子都是癌症发展变化的指示器。
They also looked for prostate specific antigen (PSA) - a protein only found in the prostate. Levels can rise if cancer is present.
他们还在寻找前列腺特异性抗原(PSA) —这是一种只能在前列腺中找到的蛋白质。
'12 cups'
‘十二杯’
The study included 26 men, aged 41 to 72 years, who had been diagnosed with prostate cancer and who were scheduled for radical prostate surgery.
研究对象包括26名年龄从41到72岁不等的男性，他们被诊断患有前列腺癌，而且他们都计划要接受彻底的前列腺手术。
Patients took four capsules containing Polyphenon E for an average of 34 days, up until the day before surgery - the equivalent of around 12 cups of normally brewed concentrated green tea.
患者每天服用四粒含有茶多酚E的胶囊，平均疗程为34天，一直到手术的前一天—这些服药量相当于十二杯普通浓度的绿茶。
The study found a significant reduction in levels of HGF, VEGF and PSA, with some patients demonstrating reductions of more than 30%.
这项研究发现血管内皮生长因子(VEGF)和肝细胞生长因子(HGF)，还有前列腺特异性抗原(PSA)都下降了，而数据显示，有些患者体内这些因子的降幅超过了30%。
Dr James Cardelli, from the Feist-Weiller Cancer Center, who led the study, said the compound, which was provided by the company Polyphenon Pharma, "may have the potential to lower the incidence and slow the progression of prostate cancer."
来自菲斯特-威勒肿瘤中心的詹姆斯·凯得利医生领导此次研究，他说，茶多酚制药公司所提供的化合物可能会降低癌症的发生率并减缓前列腺癌的恶化过程。
There were only a few reported side effects associated with this study, and liver function remained normal.
此研究只报道过一些副作用，肝功能一切都正常。
Dr Cardelli said: "We think that the use of tea polyphenols alone or in combination with other compounds currently used for cancer therapy should be explored as an approach to prevent cancer progression and recurrence." 2
凯得利医生称：“我们认为可以探寻这样一种方法来防止癌症恶化和复发，那就是单独使用茶多酚或同时使用现阶段用于治疗癌症的化合物。”
"There is reasonably good evidence that many cancers are preventable, and our studies using plant-derived substances support the idea that plant compounds found in a healthy diet can play a role in preventing cancer development and progression."
“相当具有说服力的证据显示，许多癌症都是可以预防的，我们利用源自植物的物质进行的研究也支持了以下这个观点，那就是健康的饮食能在预防癌症发展和恶化中起到积极作用。”
'Keep progression at bay'
‘防止恶化’
John Neate, chief executive of the Prostate Cancer Charity, said: "There have been several studies into green tea and its potential benefits, but there is, as yet, no conclusive evidence.
前列腺癌慈善机构的首席执行官约翰·尼特说：“对绿茶及其可能的好处已有一些研究，但至今为止仍没有定论。”
"The results of this study do suggest that there is merit in further research into the effects of extracts of green tea, both in relation to its impact on the prevention of prostate cancer and in controlling progression in men already diagnosed with the disease, as was investigated in this instance."
“这项研究结果确实表明，对绿茶成分影响的深入研究定有益处，绿茶成分既能防止前列腺癌的发生，又能控制那些已经患上前列腺癌的患者病情恶化，这些已经在实例中证实了。”
"These initial positive findings could indicate that green tea could have a place in 'active surveillance', where a slow-growing, low risk tumour is monitored for changes and men want to take something which could help keep progression at bay. “
“这些早期的积极发现都表明了绿茶可以起到‘积极监督’的作用，这些‘积极监督’能够监控那些发展缓慢、风险较低的肿瘤变化，人们都想服用一些能够防止肿瘤恶化的药物。”
"Potentially, this could mean completely avoiding, in some cases, any of the more usual medical interventions and their associated side effects."
“在某些情况下，这很可能意味着完全避免普通的医学介入及其相关的副作用。” |
