Ramie and kenaf were traditional fiber crops in China, but their stalk after decorticating has not been used effectively. The stalk contains a lot of cellulose, and can therefore be used for the production of bioethanol. We studied the effects of different chemical pretreatment on enzymatic digestibility of ramie stalk and kenaf stalk. Ramie and kenaf stalks pretreated with alkali were chosen to produce ethanol using quasi-simultaneous saccharification and fermentation (Q-SSF) process. The results show that for the stalks pretreated with 4% NaOH and 0.02% anthraquinone-2-sulfonic acid sodium salt (AQSS) as catalyzer at 170 degrees C for 1 h, the ethanol concentration could reach 51 g/L after fermentation for 168 h at 18% of solid substrate concentration. By fed-batch to 20% of solid substrate concentration, the ethanol concentration could reach 63 g/L, 77% and 79% of the cellulose conversion could get for ramie stalk and kenaf stalk, respectively. For kenaf stalk pretreated with 5.2% NaHSO3 and 0.2% H2SO4 at 170 degrees C for 1 h, the ethanol concentration and cellulose conversion could reach to 65 g/L and 72%, respectively.

Atherosclerosis is the common basic pathophysiology progresses of acute cardiovascular and cerebrovascular diseases. Atherosclerotic plaque rupture and consequently thrombosis are the major cause of mobility and mortality in atherosclerosis, and treatment aimed at stabilizing vulnerable plaques is of great clinical importance. However, an ideal drug for stabilizing vulnerable plaques is still lacking. Although Statins are considered as the most potent drugs for stabilizing plaques, their side effects are serious. Traditional Chinese medicine have multi-targets and less side effect, it might be the potential candidate for atherosclerosis treatment. This article reviewed the latest progresses on the stabilizing vulnerable plaques treatments.

Objective Ginger (Zingiber officinale) is widely used as a spice in cooking and as a medicinal herb in traditional herbal medicine. The present study was to investigate the analgesic and anti-inflammatory activities of ginger oil in experimental animal models. Methods The analgesic effect of the oils was evaluated by the acetic acid and hot-plate test models of pain in mice. The anti-inflammatory effect of the oil was investigated in rats, using rat paw edema induced by carrageenan, adjuvant arthritis, and vascular permeability induced by bradykinin, arachidonic acid, and histamine. Indomethacin (1 mg/kg), Aspirin (0.5 g/kg) and Dexamethasone (2.5 mg/kg) were used respectively as reference drugs for comparison. Results The ginger oil (0.25-1.0 g/kg) produced significant analgesic effect against chemically- and thermally-induced nociceptive pain stimuli in mice (P < 0.05, 0.01). And the ginger oil (0.25-1.0 g/kg) also significantly inhibited carrageenan-induced paw edema, adjuvant arthritis, and inflammatory mediators-induced vascular permeability in rats (P < 0.05, 0.001). Conclusion These findings confirm that the ginger oil can be used to treat pain and chronic inflammation such as rheumatic arthritis.
