Chinese Journal of Obstetrics and Gynecology 2008;43(7):528-532
Objective To study the expression of COP9,JAK2,HSP and NADH genes in ovarian carcinoma tissues after taxol-chemotherapy and their significance. Methods The up-regulated genes of JAK2, HSP, NADH and the down-regulated gune of COP9, which were revealed by micro-array from our previous study were examined by RT-PCR and real-time-PCR in 33 cases of ovarian cancer who previously received taxol-based chemotherapy (group 1 ), and 21 cases of ovarian cancer who never received chemotherapy before operation ( group 2 ) . Results The expression rate of COP9 gene in group 1 was detected markedly lower than that in group 2 (39% vs 95%, P < 0. 01 ) ; whereas the expression rates of JAK2, HSP and NADH in group 1 were significantly higher that those in group 2 (91%, 97% , 94% vs 29%, 48%, 43% ; all P < 0. 05). And the expression of COP9, HSP and NADH genes had no significant differences among histological grades. However, a significantly higher expression of JAK2 gene was seen in grade 3 than in grade 1 -2 (P <0. 01 ). No significant difference in the expression rates of the 4 genes was seen among various tumor types or chemotherapy courses ( P > 0. 05 ). Real-time PCR showed that the level of COP9 gene copies of group 1 was significantly lower than that of group 2 (568, 1866 respectively; P <0. 05 ). However, HSP, JAK2 and NADH genes had significantly higher copy numbers in group 1 than in group 2 (5766,7653,3200 in group 1 and 3341,3094,1522 in group 2, respectively; all P < 0. 05 ). In the subgroup that received 6 - 10 chemotherapy courses, the copy concentrations of JAK2, HSP, NADH genes were higher than those in the subgroup that received 2 - 4 chemotherapy courses ( all P < 0. 05 ). In addition,we found a higher copy concentrations of JAK2, HSP, NADH genes in grade 3 than in grade 1 - 2 ( all P <0. 05 ). Though no significant differences in gene copy concentrations of the 4 genes were seen among variable tumor types. In stage Ⅳ, the copy concentrations of HSP and NADH genes were higher than those in stage Ⅲ ( P < 0. 01, P < 0. 05 respectively ), but the copy concentrations of COP9, JAK2 genes had no significant differences( both P > 0. 05 ). There were positive correlations among JAK.2, HSP and NADH genes ( r =0. 56,0. 44,0. 57 respectively ,all P <0. 01 ). COP9 gene was found to have a negative correlation with JAK2 gene ( r = - 0. 48 ; P < 0. 01 ), but not with HSP and NADH genes ( r = - 0. 18, - 0. 06, respectively;both P > 0. 05 ). Conclusion The down-regulation of COP9 gene and up-regulation of JAK2, HSP, and NADH genes are related to the mechanism of drug-resistance in ovarian cancer.
2.Advance in postural orthostatic tachycardia syndrome in children
International Journal of Pediatrics 2015;42(2):193-195
Postural orthostatic tachycardia syndrome (POTS)is a clinical syndrome and the main clinical manifestation is the increase of heart rate.POTS is significantly related to position change.During the first 10 min of position change from supine to standing,if heart rate increases over a certain extent,POTS can be diagnosised.The pathogenesis of POTS has not been completely clear.The current studies show that it is closely related to the changes of central blood volume,dysautonomia,muscle pump dysfunction,vascular endothelium function disorder,etc.
