Objective To explore the change of instant blood pressure after different rehabilitation exercises for stroke patients. Methods60 stroke patients were divided into Groups A, B and C. Group A raised both arms and ante flexed shoulders >70° in seat intermittently40～50 times in 3 minutes; Group B raised both arms and ante flexed shoulders >70° in seat continually for 3 minutes (isometric); Group Cwalked slowly more than 45 steps in 3 minutes. The brachial artery blood pressure and pulse of patients were monitored before and immediatelyafter training. Results The blood pressure of Group B raised significantly after training (P<0.05). Groups A and C did not raise significantlyafter training (P>0.05). The pulse of all the groups raised and there was no significant difference among them after training (P>0.05).Conclusion Continuous persistent isotonic contraction can cause elevation of blood pressure, which patients with hypertension should avoid.

The stem and branch extract of Tripterygium wilfordii (Celastraceae) afforded seven new dihydroagarofuran sesquiterpene polyesters [tripterysines A-G (1-7)] and eight known ones (8-15). The chemical structures of these new compounds were established based on combinational analysis of HR-ESI-MS and NMR techniques. The absolute configurations of tripterysines A-C (1-3) and E-G (5-7) were determined by X-ray crystallographic analysis and circular dichroism spectra. All the compounds were screened for their inhibitory effect on inflammation through determining their inhibitory effect on nitric oxide production in LPS-induced RAW 264.7 cells and the secretion of inflammatory cytokines TNF-α and IL-6 in LPS-induced BV2 macrophages. Compound 9 exhibited significant inhibitory activity on NO production with an IC₅₀ value of 8.77 μmol·L^-1. Moreover, compound 7 showed the strongest inhibitory effect with the secretion of IL-6 at 27.36%.
