ABSTRACT
Objective:To investigate the expression of microRNA (miRNA, miR)-4699-3p in ovarian cancer cell lines, and observe its ability to regulate the expression of mitochondrial ribosomal protein S23 (MRPS23) and its effect on the migration and proliferation of ovarian cancer cells.Methods:Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-4699-3p in ovarian cancer cell lines (OVCAR-3, SKOV-3, HO-8910, OC3, A2780) and normal ovarian epithelial cells (IOSE80). The liposome transfection method was used to transfect miR-4699-3p mimic or negative control miR-NC to the cell line with the lowest miR-4699-3p expression, which was defined as the experimental group and the control group. qRT-PCR was used to verify transfection efficiency. Bioinformatics technology predicted the candidate target gene of miR-4699-3p, and the dual luciferase reporter gene experiment identified its ability to regulate the target gene. qRT-PCR and Western blot were used to detect the expression of target genes at the mRNA and protein levels. Cell counting method (CCK-8) and transwell migration experiment were used to detect the effect of miR-4699-3p on the proliferation and migration of ovarian cancer cells.Results:The expression of miR-4699-3p in ovarian cancer cell lines was significantly lower than that of normal ovarian epithelial cells ( P<0.05), and the lowest expression in OVCAR-3 cells ( P<0.01). After transfection of miR-4699-3p, the expression of miR-4699-3p in OVCAR-3 cells in the experimental group was significantly increased ( P<0.01), which proved that the transfection was successful. Bioinformatics technology predicted that the candidate target gene of miR-4699-3p may be MRPS23. The dual luciferase reporter gene experiment confirmed that miR-4699-3p can directly target the 3′-UTR of MRPS23 gene mRNA ( P<0.01). Compared with the OVCAR-3 cells in the control group, the mRNA and protein expression levels of the MRPS23 gene were significantly reduced, while the expressions of Twist, Slug, CDK6 and Cyclin D3 were significantly decreased ( P<0.01) in the experimental group after up-regulating miR-4699-3p expression ( P<0.01). After up-regulating miR-4699-3p expression, the proliferation ability of OVCAR-3 cells decreased ( P<0.05) and the migration ability of OVCAR-3 cells was reduced ( P<0.01). Conclusions:miR-4699-3p is under-expressed in ovarian cancer cell lines. Up-regulation of miR-4699-3p expression in OVCAR-3 cells can inhibit ovarian cancer cell proliferation and migration by interfering with MRPS23 gene expression.
ABSTRACT
Objective To observe the effect of modified electroconvulsive therapy combined with venlafaxine on cognitive function and its efficacy in patients with depression.Methods 60 patients with depressive disorder were selected,and they were randomly divided into study group and control group according to the random number table method,30 cases in each group.The patients in the study group accepted modified electroconvulsive therapy for 10 times combined with venlafaxine sustained-release tablets treatment,while the patients in the control group were only treated with venlafaxine.Both two groups were treated for 6 weeks.The cognitive function was assessed by the Repeat able Battery for the Assessment of Neuropsycholgical Status (RBANS) and the therapeutic effect was evaluated by Hamilton Depression(HAMD) Scale before and after treatment.Results The scores of immediate memory,delayed memory,speech function,visual breadth and attention of both two groups after treatment were significantly higher than those before treatment(all P ＜ 0.05),and the attention score of the study group was (109.96 ± 19.01) points,which was higher than (100.32 ± 17.13)points of the control group (t =2.062,P ＜ 0.05).The HAMD scores after treatment in both two groups were significantly lower compared with those before treatment (all P ＜ 0.05),and the HAMD score of the study group was (7.23 ± 4.19)points,which was lower than (10.27 ± 5.99)points of the control group (t =2.273,P ＜ 0.05).The total effective rate of the study group(96.7％) was significantly higher than that of the control group (86.7 ％) (x2 =6.546,P ＜ 0.05),and the cure rate of the study group (60.0％) was also higher than that of the control group (36.7％) (x2 =10.901,P ＜ 0.05).Conclusion Modified electroconvulsive therapy combined with venlafaxine treatment can effectively improve the cognitive function of depressive patients,and its effect is significantly better than monotherapy.
ABSTRACT
Objoctive To investigate circulating leveh of soluble vascular cell adhesion molecule-1(sVCAM-1)in the peripheral of intrahepatic cholestasis of pregnancy(ICP).To reveal the pathogenesis of ICP.Methods Maternal scram sVCAM-1 levels were determined in 49 women which 15 eases were normal pregnant women and 34 with ICP.The latter were composed of 14 women with mild,20 with severe ICP.sVCAM-1 was measured by ELISA.Results The levels of serum sVCAM-1 was significantly elevated in women with mild and severe compared with control subjects(P＜0.01),and markedly decreased to normal 5 days after dilively(P＞0.05).The sVCAM-1 level were negatively correlated with weight of neonatal(r=-0.643,P＜0.01).Conclusion Elevated levels of sVCAM-1 indicate that a primary endothelial cell dysfunction play an important role in the ICP.And it influences the neonatal.
