In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

Objective To analyze the clinical manifestations of early cerebral ischemic lesions after stenting with WingSpan system for symptomatic intracranial artery stenosis, and to evaluate the early effects and safety of the stenting therapy. Methods Twenty-nine consecutive patients with symptomatic intracranial stenosis underwent diffusion weighted imaging (DWI) before and after stenting (within 72 hours). The clinical data, including patients' general condition, stenting procedures and newly-developed cerebral ischemic lesions, were recorded. Neurological defect was estimated with NIHSS, the safety and early outcome of stenting were evaluated. Results The degree of stenosis was reduced from a mean baseline of (72.3 ± 10.7)% to (31.9 ± 13.6)% immediately after stenting. The technical success rate was 100%. The total eomplicatiom nate was 17.2%. And among them, z were symptomatic (6.9%). Sixty-three ischemic lesions were demonstrated on DWI in 13 patients (44.8%). Among them, 11 (84.6%) were asymptomatic. Fifty-five newly-developed lesions on DWI (87.3%) were located in the region of stented vessels and 3.2% were situated in the region of branch vessels of stented artery. Conclusion DWI is of great value in assessing the safety of intracranial stenting procedures. The treatment of symptomatic intracranial artery stenosis by using WingSpan system is safe and effective. Newly-developed ischemic lesions can be well detected on DWI and should receive physician's attention, although most ischemic lesions are asymptomatic. Long-term outcome of this treatment needs to be further observed.
