Eclipta prostrata, a traditional Chinese medication, has been used for the treatment of several diseases. However, the molecular mechanism underlying the effects of Eclipta prostrata extracts (EPE) on human oral cancer cell metastasis remains unclear. We thus examined the effects of EPE on metastasis promoting proteins in oral cancer. Our results revealed that the EPE attenuated SCC-9, HSC-3, and TW2.6 cell migration and invasiveness by reducing matrix metalloproteinase (MMP)-2 enzyme activities. In addition, Western blot analysis revealed that EPE significantly reduced the levels of phosphorylated extracellular signal-regulated kinase 1/2 (ERK 1/2) but not those of c-Jun N-terminal kinase (JNK) 1/2 and p38. In conclusion, we found that EPE could inhibit oral cancer metastasis through the inhibition of MMP-2 expression. Therefore, EPE may be used to prevent the metastasis of oral cancer, and has the potential to be applied to cancer treatment.

This longitudinal study evaluated the direct effects of providing/receiving family support on mortality in older adults with different living arrangements in Taiwan. All data analysed were obtained from the Taiwan Longitudinal Study on Aging, 1996–2007, of residents aged ⩾67 years (1,492 men and 1,177 women) and Taiwan's National Death Register. Living arrangements were divided into living alone, living only with spouse, living with family and living with others. Support was mainly defined as family support divided into two categories: providing and receiving. The effect of providing/receiving family support on the mortality of older adults was evaluated using Cox regression analysed by living arrangement. Participants living with their families had lower educational levels (illiterate or elementary school) and more disability in both activities of daily living and instrumental activities of daily living. However, they provided more family support than those in other living arrangements. After adjusting for several potentially confounding variables, including background characteristics, economic status and various health status measures, results showed that older adults living with their families and providing support had an 11 per cent lower mortality rate (Hazard ratio = 0.89; 95 per cent confidence interval = 0.83–0.96; p = 0.0018). In conclusion, we found that, when living with family, the lives of older adults can be extended by providing support, clearly supporting the old adage ‘it is more blessing to give than to receive’. Older adults wanting to extend their lives can be encouraged to provide more help to their families.

Providing instrumental social support to others confer benefits to the giver and prolong life expectancy among the elderly with low educational levels.

This clinical trial was conducted to assess the lipid-lowering activity of oat noodles by replacing partial staple food (wheat or rice noodle) in normal and mildly hypercholesterolemic subjects. Totally 84 healthy and mild hypercholesterolemic subjects were recruited and divided into 2 groups as experimental (oat noodles) and placebo (wheat noodles) and instructed to consume 100 g of oat noodles or wheat noodles (replacing one or two meals/day) for 10 weeks and followed by 2 weeks of follow up (without noodle consumption). Various anthropometric measurements and biochemical analysis were carried out during initial (baseline), 2nd, 6th, 10th and 12th week (follow-up). Consumption of oat noodles by replacing staple food for 10 weeks significantly reduced (**p < 0.01) the levels of total cholesterol (TC; 17.46%) and low-density lipoprotein LDL-c (19.03%) in both healthy and mildly hypercholesterolemic subjects. However, the hypocholesterolemic effect is significantly higher in mildly hypercholesterolemic subjects as compared with normal subjects. A pronounced decline (*p < 0.05) in the levels of various cardiovascular diseases (CVDs) markers including TC/HDL and LDL/HDL ratios and blood pressure (SBP; 11.09% and DBP; 7.48%) were observed in oat noodles supplemented subjects as equivalence with the placebo group. The partial replacement of staple food with oat noodle could considerably improve the health status of all subjects especially in hypercholesterolemic subjects and thus lower the risk of CVDs.
