Intracerebral hemorrhage is a neurological emergency with high disability and mortality. Studies have demonstrated that thrombin formation,erythrocytolysis and iron ions play important roles in the brain injury after intracerebral hemorrhage. This article reviews the mechanisms of thrombin and iron ions in intracerebral hemorrhage-mediated brain injury.

Aim To investigate the mechanism of achyranthes bidentata polysaccharides on degranulation of mast cells. Methods The experiment of passive cutaneous anaphylaxis was used to determine the effect of achyranthes bidentata polysaccharides on degranulation of mast cells in vivo. For in vitro study, various doses of achyranthes bidentata polysaccharides were added to the culture medium of sensitized RBL-2H3 cells. The antigen-induced release of degranulation was measured by enzymatic assay, histamine by EIA and cytokines by ELISA. In addition, the activation of Akt and p38 were measured by Western blot. Results Treatment with achyranthes bidentata polysaccharides was followed by a decrease in PCA of rats and ?-hexosaminidase, histamine, TNF-?,IL-4,Akt and p38 of RBL-2H3 cells induced by antigen. Conclusions Achyranthes bidentata polysaccharides might suppress the anaphylactic reaction through inhibition of action of mast cells. Akt and p38 contributed at least in part to this event.

Smilax macrophylla is a type of Chinese herbal medicine for the treatment of gouty arthritis. Study on its quality evaluation method was very necessary. Resveratrol (trans-3,5,4'-trihydroxystilbene), its generally acknowl-edged major compound with definite therapeutic effect, was detected in the root of S. macrophylla. HPLC was used with the mobile phase of acetonitrile-water (25:75). The detection wavelength was 320 nm. The results showed that the method can be used in content determination of resveratrol in S. macrophylla. It was concluded that the study was able to establish content determination method of resveratrol in S. macrophylla in order to lay the foundation of the establishment of quality standard of this Chinese herbal medicine.

OBJECTIVETo investigate the clinical applicability and outcomes of the combined radical operation without breaking the lower lip and mandible with one-stage reconstruction using free anterolateral thigh flap for tongue and lingual root carcinoma.

METHODSThe operation with or without breaking lower lip and mandible was performed respectively in 245 patients (experimental group) and 120 patients (control group).

RESULTSRemoval of tumor and neck dissection were conducted successfully in all patients of two groups with no serious postoperative complication. With the follows-up of 6 to 36 months, in the patients of experimental group there was no recurrence for primary sites but 3 cases with neck lymphnode recurrence, the functions of chewing, swallowing and speaking were good, there was no damage to appearance, and no osteoradionecrosis occurred in the lymphnode positive cases after radiotherapy; in the patients of experimental group there was no recurrence for primary sites but 4 cases with neck lymphnode recurrence, the functions of chewing, swallowing and speaking were good, but there was apparent scar in neck and face, and osteoradionecrosis occurred in 11 of lymphnode positive cases.

CONCLUSIONSThe combined radical operation without breaking the lower lip and mandible with one-stage reconstruction using free anterolateral thigh flap is feasible for tongue and lingual root carcinoma (T2-T3), which reduces the risk for osteoradionecrosis in lymphnode positive cases after radiotherapy and keeps good appearance for patients.
