Allyl isothiocyanate (AITC) has been found to present sources from consumed cruciferous vegetables. AITC is known to possess pharmacological and anticancer activities. The present study was designed to test the hypothesis that AITC suppressed the invasion and migration of epidermal growth factor (EGF)-stimulated HT29 cells and to elucidate the mechanisms for the antimetastatic abilities in vitro. The invasion and migration of EGF-stimulated HT29 cells were determined individually by Transwell cell invasion and wound-healing assays. Our results showed that AITC effectively inhibited both the invasive and migratory ability of HT29 cells. Furthermore, AITC downregulated the protein levels of matrix metalloproteinase-2 (MMP-2), MMP-9 and mitogen-activated protein kinases (MAPKs) (p-JNK, p-ERK and p-p38) by western blot analysis in HT29 cells following EGF induction. Thus, the metastatic responses in AITC-treated HT29 cells after EGF stimulation were mediated by the MMP-2/-9 and MAPK signaling pathways. We also used gene expression microarrays to investigate the gene levels related to cell growth, G-protein coupled receptor, angiogenesis, cell adhesion, cell cycle and mitosis, cell migration, cytoskeleton organization, DNA damage and repair, transcription and translation, EGFR and PKB/mTOR signals. In summary, it is possible that AITC suppresses the invasion and migration of EGF-induced HT29 cells, resulting from MMP-2/-9 and MAPKs. Hence, AITC may be beneficial in the treatment of human colorectal adenocarcinoma in the future.

Background. Guilu Erxian Jiao (GEJ) is a widely used Chinese herbal remedy for knee osteoarthritis, but its clinical efficacy is unknown. Methods. We enrolled 42 elderly male patients with knee OA, including 21 patients who received the herbal drug GEJ as the case group and 21 patients who did not receive GEJ as the control group. The effects of 12 weeks of GEJ treatment on muscle strength of lower limbs were measured by a Biodex dynamometer, with disability evaluated on the Lequesne index and articular pain measured on the visual analog scale (VAS) between the two groups on the baseline and after treatment. Results. There were significant increases in the levels of muscle strength of TQ/BW-ext-dominant and TQ/BW-flex-dominant between the two groups after treatment (P < 0.05). There were also significant increases in muscle strength of knee extensor muscles in the GEJ-treated group (n = 21) self-controlled before and after 12 weeks of treatment (all P < 0.01). There were significant decreases in articular pain (P < 0.01) and Lequesne index scores (P < 0.01) in the GEJ-treated group when compared to the non-GEJ-treated group. Conclusions. Our results showed that GEJ is effective and is tolerated well in elderly men with knee OA.

Total testosterone level is significantly related to metabolic and inflammatory factors in elderly men. Low total testosterone may be a significant indicator for development of metabolic syndrome in elderly men.

Both glyburide/metformin 2.5 mg/500 mg and glyburide/metformin 5.0 mg/500 mg combination therapy were efficacious and well tolerated in the treatment of Chinese patients with type 2 diabetes mellitus.

It is known that osteoporosis decreases physical function in older males. However, the role of metabolic parameters and physical activity influencing older men's bone status remains unclear. Thus, this study was designed to evaluate calcaneus bone mass by ultrasonic screening and the associated physical and metabolic functions in older men. This was a cross-sectional study. Three hundred sixty-eight older men (average age, 78.8 years) living in a veterans' home were enrolled. We measured body height and weight, waist and hip circumference, body fat, lean body mass, blood pressure, 6-min walking distance, complete blood count, and blood biochemical profile. Broadband ultrasound attenuation (BUA) and T-score were recorded using Soundscan quantitative ultrasound over the right calcaneus. The range of calcaneus BUA was 27.3-134.0; T-score was from -4.78 to 3.43. Of the total participants, 36.4% were osteopenic (-2.5 < T-score < -1.0) and 16.3% were osteoporotic (T-score
