Objective To observe the effect of β-asarone on the proliferation, cycle, apoptosis and migration of tumor cells A549, PC3, and PC9-R, thus to provide experimental basis for the application of β-asarone to the treatment of cancer. Methods After A549, PC3, and PC9-R were cultured with different concentrations ofβ-asarone for 24 h, 48 h, and 72 h respectively, CCK-8 was used to detect the optical density (D) of cell proliferation, and then the cell proliferation rate was calculated. The flow cytometry was used to measure the cell DNA cycle and cell apoptosis, and Transwell Chambers were used to detect the cell migration. Results After treatment with different concentrations of β-asarone for 24 h, 48 h, and 72 h respectively, the growth of A549, PC3, and PC9-R showed declining trend in concentration- and time-dependent manner. The proportion of A549, PC3, and PC9-R at G0/G1 phase was increased, the proportion of the three kinds of cells at S phase and the proliferation indexes were declined, the apoptotic rate of A549, PC3, and PC9-R was increased, and the migration of A549, PC3, and PC9-R was reduced (P<0.05 or P<0.01 compared with those of the normal control group). Conclusion β-asarone has certain effects on suppressing proliferation, blocking G0/G1 phase developing into S phrase, inhibiting DNA synthesis, promoting the apoptosis, and inhibiting the migration of A549, PC3 and PC9-R.

This paper summarized Professor ZHUANG Lixing's clinical experience in differentiating and treating levodopa-induced dyskinesia （LID） in Parkinson's disease. It is believed that the fundamental pathogenesis of LID lies in the disharmony or malnourishment of tendons and vessels. Based on the clinical manifestations， peak-dose LID is differentiated into two syndromes： syndrome of hyperactive liver yang causing wind and syndrome of deficiency of both liver and kidney. For the syndrome of hyperactive liver yang causing wind， the treatment focuses on calming the liver to stop the wind， and relaxing the tendons to stop tremors. The main prescription used is Zhengan Xifeng Decoction （镇肝熄风汤） with the addition of Shijueming （石决明） and Zhenzhumu （珍珠母）. For the syndrome of deficiency of both liver and kidney， the treatment focuses on nourishing the liver and kidneys， and replenishing yin to stop the wind. The main prescription used is Dabuyin Pills （大补阴丸） with modification. LID in the acoustic phase is differentiated into syndrome of phlegm-damp blocking middle jiao and syndrome of deficiency of both qi and yin. For the syndrome of phlegm-damp blocking middle jiao， the treatment focuses on dissipating phlegm and eliminating dampness， and nurturing tendons and vessels. Wendan Decoction （温胆汤） or Erchen Decoction （二陈汤） with modification is used. For the syndrome of deficiency of both qi and yin， the treatment focuses on replenishing qi and nourishing blood， and nurturing tendons and vessels. The main prescriptions used are Buzhong Yiqi Decoction （补中益气汤） or Bazhen Decoction （八珍汤） or Shenling Baizhu Powder （参苓白术散） with modification. Biphasic LID is differentiated as the Shaoyang pivot disadvantageousness， and the treatment focuses on harmonizing Shaoyang and regulating the pivot. The main prescription used is Xiaochaihu Decoction （小柴胡汤） with modification.
