Cognitive behavior therapy (CBT) has been proved to be an effective psychological treatment method for depression,especially for mild-to-moderate depression,however,due to the influence of various factors,its application in patients with depression is limited.Studies abroad have confirmed self-help intervention based on CBT has good effects on patients with depression.By reviewing efficacy of self-help interventions based on CBT on depression,it can be known that most of the literatures support that self-help interventions based on CBT has good effects on depression.Related researches abroad have been more mature,but few similar studies have been conducted in our country.So self-help CBT for depression has broad prospects in our country,which can play an important role in the prevention and therapy of depression,alleviating the shortage of medical resources,and reducing the patients' medical expenses,etc.Based on bibliotherapy (a major form of self-help interventions based on CBT),future studies need to learn from foreign practice to expand the audience to the clinic,community and non-clinical patients,in order to provide advice for interventions for depression in China.

Background and purpose:The expression ofRab11 gene was increased incervical cancer cell and may be involved in the cellular malignant transformation. This study used the sequence-speciifc siRNA knocking down the expression of Rab11 gene and aimed to investigate its effect on invasion and migration of cervical cancer cell lines HeLa/SiHa and its mechanism.Methods:HeLa/SiHa cells were divided into 2 groups: non-speciifc siRNA group transfected with unrelated siRNA (Rab11-NC) and Rab11 siRNA group transfected with Rab11 siRNA (Rab11siRNA). Western blot was used to examine the Rab11 protein expression. Cell migration and invasion were detected by cell scratch and Transwell invasion assay. Western blot was used to further investigate the expression of Rac1, matrix metal-loproteinase 2 (MMP2) and MMP9 which were critical for regulating cell invasion. Moreover, immunolfuorescence was used to identify intracellular location of Rac1 in HeLa/SiHa cells.Results:The Rab11 siRNA inhibited expression of Rab11 gene (P<0.01). The invasion and migration capacities of HeLa/SiHa cells were markedly inhibited in Rab11siR-NA group (P<0.05). The expression of Rac1 signiifcantly decreased (P<0.01). The expression of MMP2 and MMP9 de-creased (P<0.05) as well. The recruitment of Rac1 to protruding edge signiifcantly decreased following down-regulation of Rab11.Conclusion:Down-regulatedRab11 expression could inhibit the expression of Rac1, MMP2 and MMP9, and alter the location of Rac1, leading to suppression of HeLa/SiHa cells migration and invasion.
