OBJECTIVETo observe the immediate antihypertensive effect of guasha combined with bleeding therapy for mild (grade I) hypertension.
METHODSThirty patients with mild (grade I) hypertension and 30 cases with normal blood pressure were compared. Areas and acupoints in governor vessel, meridian of foot-taiyang, meridian of hand-yangming and meridian of foot-yangming were scraped for 3 times, which was followed by bleeding therapy. The blood pressures after each guasha and bleeding therapy were recorded as well as the skin temperature in Dazhui (GV 14) after each guasha. The treatment was given once a week and totally 4 treatments were given.
RESULTSThere were significant antihypertensive effects after the first guasha, the second guasha and the third guasha and bleeding therapy (all P<0.01), in which guasha combined with bleeding therapy had the most significant antihypertensive effect (P<0.01). The skin temperature in Dazhui (GV 14) was obviously increased after three times of guasha (all P<0.01).
CONCLUSIONGuasha or combined with bleeding therapy has better antihypertensive effect for mild hypertension, which is likely to be related with warming stimulation on meridians and acupoints.

Aim To study the apoptosis effect of Sir-aitia grosvenorii extract on human lung cancer cells A549 and its mechanisms.Methods MTT assay was applied to determine A549 cell proliferation.Hoechst 33258 staining was applied to investigate morphological changes in A549 cells.To find out the cause of cell growth inhibition,several experiments on cell cycle distribution and apoptosis were performed by flow cy-tometry analysis.The expression of p21 and Bcl-2 was determined by Western blot.Results Flow cytometry analysis showed that treatment with mogrol arrested A549 cells in the G0 /G1 phase and induced apoptosis. After treatment with Siraitia grosvenorii extract,West-ern blot experiment showed cell cycle regulator p21 was up-regulaed,while the apoptosis inhibitor Bcl-2 was down-regulated.Conclusion Treatment with Siraitia grosvenorii extract arrests the A549 cells at G0 /G1 phase and induces apoptosis that may contribute to the anti-proliferation activity of mogrol through the regula-tion of p21 and Bcl-2 expression.
