生活中的“眼保姆”

你在工作中经常使用电脑吗?眼睛有干涩、血丝、怕光,流泪,甚至红肿的现象吗?如果有,说明你的眼睛已经受到了伤害。眼睛疲倦的原因一般与眼泪的分泌物有关,这要引起你的重视,并要加倍保护眼睛,而如果能在饮食中加入一些营养眼睛的食物,是最方便最有效的方法。     

RRR—α—tocopheryl succinate inhibits human gastr cancer SGC—7901 cell growth by inducing apoptos and DNA synthesis arrest

AIM: To investigate the effects of growth inhibition of human gastric cancer SGC-7901 cell with RRR-alpha-tocopheryl succinate (VES), a derivative of natural Vitamin E, via inducing apoptosis and DNA synthesis arrest. METHODS: Human gastric cancer SGC-7901 cells were regularly incubated in the presence of VES at 5, 10 and 20mg x L(-1) (VES was dissolved in absolute ethanol and diluted in RPMI 1640 complete condition media correspondingly to a final concentration of VES and 1 mL x L(-1) ethanol), succinic acid and ethanol equivalents as vehicle (VEH) control and condition media only as untreated (UT) control. Trypan blue dye exclusion analysis and MTT assay were applied to detect the cell proliferation. Cells were pulsed with 37kBq of tritiated thymidine and (3H) TdR uptake was measured to observe DNA synthesis. Apoptotic morphology was observed by electron microscopy and DAPI staining. Flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay were performed to detect VES-triggered apoptosis.RESULTS: VES inhibited SGC-7901 cell growth in a dose-dependent manner. The growth curve showed suppression by 24.7%, 49.2% and 68.7% following 24h of VES treatment at 5, 10 and 20 mg x L(-1), respectively, similar to the findings from MTT assay. DNA synthesis was evidently reduced by 35%, 45% and 98% after 24h VES treatment at 20mg x L(-1) and 48 h at 10 and 20mg x L(-1), respectively. VES induced SGC-7901 cells to undergo apoptosis with typically apoptotic characteristics, including morphological changes of chromatin condensation, chromatin crescent formation/margination, nucleus fragmentation and apoptotic body formation, typical apoptotic sub-G1 peak by flow cytometry and increase of apoptotic cells by TUNEL assay in which 90% of cells underwent apoptosis after 48 h of VES treatment at 20 mg x L(-1). CONCLUSION: VES can inhibit human gastric cancer SGC-7901 cell growth by inducing apoptosis and DNA synthesis arrest. Inhibition of SGC-7901 cell growth by VES is dose- and time-dependent. Therefore VES can function as a potent chemotherapeutic agent against human gastric carcinogenesis.

据台湾中广新闻援引美联社报道：维他命E与硒对预防前列腺癌作用不大

据台湾中广新闻援引美联社报道，美国政府已经停止进行一项关于维他命E与矿物质元素“硒”是否有助于预防摄护腺癌（即前列腺癌）的研究，因为已经有足够证据显示，这两种元素对防止摄护腺癌，作用不大。

皮肤科医师Q&A

Q用热水洗脸会不会洗得比较干净? A理论上会的。就像你在洗盘子一样,很油的盘子,拿到热水下一冲,油就被水冲走了,甚至不用洗碗精呢。可是皮肤医师却不建议大家用热水洗脸,因为洗脸用品中的界面活性剂
