RESUMEN
OBJECTIVE@#To study the role of dopamine D3 receptor involved in the amphetamine-induced conditioned place preference (CPP) in mice.@*METHODS@#The CPP was observed in D3 receptor knock-out (D3RKO) mice and C57BL/6 wild-type control mice after administration of amphetamine. The data were analyzed with a two-way ANOVA using the SPSS 13.0 software.@*RESULTS@#D3RKO mice showed a significant amphetamine-induced CPP (P<0.001), compared with the ones administered with saline in C57BL/6 control mice.@*CONCLUSION@#The results indicate that amphetamine can produce significant CPP in dopamine D3 receptor knock-out mice, suggesting that amphetamine-induced addiction can be inhibited by dopamine D3 receptor.

Objective To study the related factors of recurrence after myomectomy. Methods The clinical data of 441 cases with myomectomy were collected. The age at the time of operation, body mass index(BMI), preoperative parity, and the location, size and number of myomas were recorded, and the postoperative recurrence rate was calculated. Univariate and multivariate analysis were performed for possible factors related to recurrence. Results The average time of follow-up was(37.79?18.64) months. Recurrence was found in 125 cases, and 5-year cumulative rate of recurrence was 38.9%. The age at the time of operation, BMI, number of myomas and preoperative parity were related factors of recurrence(P
RESUMEN
Gene chip is a research tool on molecular biology which can detect generous gene expression rapidly.The studies on gene chip of leiomyoma have revealed the changes of gene expression related to cell growth,proliferation,apoptosis,metabolism,angiogenesis,formation of extracellular matrix,cell differentiation and immunity.The article reviews the advance on gene chip of leiomyoma and approaches the pathogenesis of leiomyoma on molecular level.
