Objective: To investigate the effect of RNA interference (RNAi) targeting AKT1 and PI3K P85 on the proliferation and invasion of breast carcinoma MCF-7 cells. Methods: The recombinant adenovirus expression vector, which contained short hairpin RNA (shRNA) targeting open reading frames of AKT1 and PI3K P85 (rAd5-siAKT1-siPI3K), was transfected into human breast carcinoma MCF-7 cells. AKT1 and PI3K P85 mRNA and protein expressions were detected by real-time PCR and Western blotting analysis. The expressions of PCNA, cyclinD1, and P53 were also detected by Western blotting analysis. The proliferation and apoptosis of MCF-7 cells were measured by MTT, flow cytometry and 2-dementinal and 3-dementional matrigel assay. Results: Recombinant adenovirus vector rAd5-siAKT1-siPI3K dramatically down-regulated AKT1 and PI3K P85 mRNA and protein expressions in MCF-7 cells; the downstream factors PCNA and cyclin D1 were also down-regulated, while P53 was up-regulated. Growth of MCF-7 cells was inhibited by over 50% in rAd5-siAKT1-siPI3K group as measured by MTT assay, and cell cycle was arrested in G_1/G_0 phase compared with untransfected and rAd5-siCtrl transfected groups. Cell growth on matrigel matrix showed normal cell shapes, while the cells in rAd5-siAKT1-siPI3K transfected group were detached from the matrix or grew in scattered clustering patterns, forming only small aggregates. Conclusion: shRNA targeting AKT1 and PI3K P85 can significantly down-regulate the expression of AKT1 and PI3K P85 in breast carcinoma MCF-7 cells, and inhibit the growth of MCF-7 cells in vitro.

Objective: To study the effect of and possible mechanism of knockinng down PI3Kp85α using siRNA in MCF-7 human breast cancer cell line. Methods: Oligofectamine was used to transfect PI3Kp85α siRNA to knock down the PI3Kp85α expression level in MCF-7 human breast cancer cell line in vitro. Real-time PCR was conducted to detect the expression of PI3Kp85α. The effect of PI3Kp85αsiRNA on the growth of MCF-7 cells was measured by MTT. The cell cycle distribution and cell apoptosis were detected by cell flow cytometry. Protein expression was evaluated by immunofluorescence staining and Western blot. Results: The expression of PI3Kp85 α was knocked down with PI3Kp85α siRNA in MCF-7 cells. Cell growth was delayed in PI3Kp85αsiRNA-treated group. Conclusion: The suppressive effect of PI3Kp85αsiRNA on the growth of MCF-7 human breast cancer cell line is significant and PI3Kp85α could be a candidate for gene therapy for breast cancer.

Objective To study the effect of intensive trunk muscle training on balance and walking in pa- tients with hemiplegia caused by stroke.Methods A total of 90 stroke patients were recruited and randomly divid- ed into a treatment group(45 cases)and a control group(45 cases).All the patients were given conventional reha- bilitation training.Meanwhile,intensive trunk muscle training was also administered for those in the treatment group as well.The trunk control function,balance ability and walking ability were assessed by using the trunk control test, Berg Balance Scale and the balance subscale of the Fugl-Meyer physical performance test,and Holden's functional ambulation classification,respectively,before and after 6 weeks of training.Results It was found that all the pa- tients scored better with the trunk control test,Berg's balance scale,the balance subscale of the Fugl-Meyer physical performance test and Holden's ambulation classification after treatment,and there were significant differences between the two groups after treatment(P

Objective To study the influence of electro-acupuncture(EA)at Zusanli points(足三里穴) on the apoptosis of thymocytes in rats with abdominal infection and its mechanism.Methods A total of 40 Sprague-Dawley(SD)rats were randomly divided into four groups,including normal control group,model group,non-acupoint group and Zusanli group.The abdominal infection model of rat was made by cecal ligation and puncture(CLP).After abdominal cavity infection for 36 hours,the apoptosis of thymocytes was observed under electron microscope and light microscope,and the apoptosis ratio of thymocytes was determined by Annexin V-PI method with flow cytometry technique.The content of Bcl-2 protein of thymocytes and concentration of corticosterone in plasma were determined.Results Abdominal infection resulted from CLP could significantly increase the apoptosis of thymocytes and lead to the typical histopathological changes of apoptosis of thymocytes under electron microscope and light microscope.Apoptosis ratios of thyrnocytes in model group[(44.7?3.3)%],non-acupoint group[(42.7?3.0)%]and Zusanli group[(32.6?3.3)%] were significantly higher than the ratio in the control group[(21.2?2.3)%,all P0.05).Abdominal infection resulted from CLP also could reduce the content of Bcl-2 protein of thymocytes.The content of Bcl-2 protein of thymocytes in model group(71.2?5.6),non-acupoint group(73.5?5.9)and Zusanli group(82.4?6.8) were significantly lower than normal control group(95.3?6.3,all P
