The Journal of Practical Medicine 2015;(13):2095-2097
Objective To investigate the effects about Tetramethyl -pyrazine (TMP)to Bad, Caspases-1 protein relating with JNK signal transduction pathways on cultured rat hippocampal neurons after anoxia-reoxygenation. Methods Rat hippocampal neurons were cultured in vitro and observed respectively on 7 ~ 9 days. Neurons were exposed to TMP in three different concentration (60,200,800 μg/mL) and JNK inhibitors (10 μmol/L). Control/normal groups were set in each experiment, except for the normal group. After 1 hour of treatment, the rat hippocampal neurons were placed in an incubator with 90%N2 + 10% CO2 for 2 hours to induce anoxia. Then, the rat hippocampal neurons were placed in an incubator with 5% CO2+95%air to establish reoxygenation. Bad, Caspases-1 protein were examined by Western Blot. Results After neurons with 60,200, 800 μg/mL TMP and 10 μmol/L JNK inhibitors on damage induced by anoxia-reoxygenation , the Bad , Caspases-1 protein are lower than the control group. But the 200 μg/mL group is better than 60 800 μg/mL groups. Conclusions Through the JNK signal transduction pathways, the Caspases-1, Bad protein expressions are lower than the control group. So TMP has obvious inhibitory action to rat hippocampal neuronal damage induced by anoxia-reoxygenation.

Acta Pharmaceutica Sinica 2015;50(1):111-7
The transplants of one-year-old Glycyrrhiza uralensis Fisch. were subjected to five concentrations of MnSO4-H2O (0, 1.81, 18.1, 36.2 and 54.3 mg·L(-1)) culturing in vermiculite. qRT-PCR and HPLC were respectively used to measure the relative expression of SQS1 gene and the content of glycyrrhizic acid of G. uralensis in different concentrations of MnSO4·H2O. This is to explore discuss the effects of the expression of SQS1 gene and the accumulation of glycyrrhizic acid by Mn treatment. The results showed both the expression of SQS1 gene and the content of glycyrrhzic acid of G. uralensis tended to rise after the fall of the first with the increase of concentration of Mn treatment. And they were of very significant positive correlation (P<0.01, r=0.737). Relative expression of SQS1 gene reached the highest 7.90 under 18.1 mg·L(-1) MnSO4·H2O treatment. It was very significantly different between 18.1 mg·L(-1) concentration of MnSO4·H2O treatment and CK (0 mg·L(-1)), 1.81, 36.2 and 54.3 mg·L(-1) (P<0.01), and 1.75, 1.37, 1.37, 2.33 times respectively. The content of glycyrrhizic acid reached the highest under 1.81 and 18.1 mg·L(-1) MnSO4·H2O treatment, and there were not significant difference (P>0.05). It was very significantly different between them and other concentrations of MnSO4·H2O treatment (P<0.01). This study suggests the appropriate concentration of Mn treatment could certain promote the expression of SQS1 gene and the accumulation of glycyrrhizic acid of G. uralensis.
