Résumé
Objective To explore the effects of butylphthalide on the apoptosis of SH-SY5Y cells induced by the 1-methyl-4-phenylpyri-dinium iodide (MPP+). Methods SH-SY5Y cells were cultured with butylphthalide in the dosage of 1 μmol/L, 10 μmol/L and 20 μmol/L for 2 hours, and with MPP+for 24 hours. The viability of cells was measured with trypan blue. The mitochondrial membrane potential was de-tected with Rhodamine 123. The content of P53 protein was detected with ELISA. The expression of P53 and cytochrome C (CytC) were de-tected with Western blotting. Results The viability of SH-SY5Y cells increased with the dosage of butylphthalide (P<0.05), while the mito-chondrial membrane potential and the expression of P53 and CytC decreased (P<0.05). Conclusion Butylphthalide can prevents the SH-SY5Y cells from the injury induced by MPP+, which may associate with the inhibition of apoptosis through the expression of P53 and CytC.

Objective To analyze the correlation between non-motor symptoms (NMS) and the quality of life in the mild Parkinson's disease (PD) patients of different genders.Methods 85 mild PD patients (H-Y stage 1～2) were investigated.The PD NMS Quest was used to assess NMS.The quality of life was assessed with SF-36 questionnaire.Results Stepwise linear regression analysis showed that nocturia,restless legs,depression,daytime sleepiness,decreased interest,smell taste problems were positively correlated with the score of life quality of male and pain,increased sweating,taste smell problems,sleep problems,changes in libido,decreased memory,diplopia influenced life quality score of female.The scores of SF-36 questionnaire of the male with PD were lower than that of female patients.Conclusions The nonmotor symptom (NMS) There was a gender difference about the influence that NMS has made on PD patients.The male's life quality were lower than that of female patients about mild PD patients.
