Abstract BACKGROUND: Large amounts of data have shown that Chinese herbal monomer has a neuroprotective effect, and can improve the quality of life in stroke patients with cerebral nervous system injury. Nuclear-factor-erythroid 2-related (Nrf2) factor has neuroprotective effect on hemorrhagic stroke and ischemic stroke, which is an important way to reverse the damage of nervous system through the natural non-toxic Chinese herbs or composition, but it is rarely reported systemicaly. OBJECTIVE:To summarize the neuroprotective effect of Chinese herbal monomersvia the Nrf2 signal pathway in stroke patients. METHODS:The first author retrieved the CNKI, VIP, Medline, and PubMed databases by computer. The keywords were “Nrf2, ARE, stroke, traditional Chinese medicine, neuroprotection” in Chinese and English,respectively. Articles concerning the neuroprotective role of Chinese herbal monomervia Nrf2 were analyzed and discussed. RESULTS AND CONCLUSION: Totaly 85 articles were retrieved. According to the inclusion and exclusion criteria, 46 articles were included in result analysis. The results show that a variety of monomers can exert neuroprotective effectsvia the Nrf2 pathway. Chinese herbal monomers include organic acids, phenols, saponins, terpenes, flavonoids, alkaloids, and other single or composite components. Traditional Chinese medicine has the clear neuroprotective effect after stroke, but it is lack of regularity, and it is stil need to expand the data and further research as the basis.

Objective To investigate the inhibition mechanism of tetramethylpyrazine combined with cisplatin on angiogenesis in Lewis lung cancer mice and to observe the mechanism of Arresten on angiogenesis in lung cancer. Methods The model of Lewis lung adenocarcinoma mouse xenograft was established in this work, and 40 mice were randomly divided into 4 groups: 0.9% sodium chloride solution group(NS group), tetramethylpyrazine group(TMP group), cisplatin group(DDP group), tetramethylpyrazine plus cisplatin group(TMP + DDP group), 10 mice in each group.Mice in NS group were given 0.2 mL of 0.9% sodium chloride solution, mice in DDP group were given 0.2 mL of 2 mg.kg-1 of cisplatin, mice in TMP group were given 0.2 mL of 100 mg.kg-1 of tetramethylpyrazine, mice in TMP+DDP group were given 2 mg.kg-1 of cisplatin and 100 mg.kg-1 of tetramethylpyrazine, each 0.1 mL .Tumor size was measured every day to calculate the tumor volume.The mice were sacrificed to stripp the subcutaneous tumor after continuous medication. The expressions of Arresten, integrin α1β1 and VEGF were determinated by immunhistochemistry and Western blotting. Results The tumor growth of NS group was the fastest and TMP+DDP group was the slowest. Compared with NS group, the expression of Arresten in the other three groups was increased( P<0.01) , and the TMP+DDP group exhibited the highest expression;at the same time, integrin α1β1 , VEGF in the other three groups was decreased(P<0.01), and the TMP+DDP group exhibited the lowest expression.The expression of integrinα1β1 and VEGF was negatively related to Arresten, and the expression of integrin α1β1 was positively correlated with VEGF. Conclusion TMP can inhibited the growth of Lewis lung carcinoma and angiogenesis. Moreover, in combination with cisplatin, TMP can also improved the effect of chemotherapy and then the survival state of mice. The mechanism of action, which TMP suppress tumor angiogenesis may be through improving Arresten and inhibiting integrin α1β1 and VEGF. And the action mechanism of Arresten may be implemented by inhibiting the expression of VEGF by incorporation with integrinα1β1 or by itself to inhibit the expression of VEGF.
