Objective To inhibit the expression level of SALI4 in AML cell line THP-1 and investigate its potential effects on pathogenesis of leukemia. Methods AML cell line THP-1 was transfected with plasmids that expressed small interfering RNA targeting SALL4. The samples were divided into 4 groups:(1) blank group: samples with not any treatments; (2) control group: cells with empty pRS vector alone;(3) test1 group:cells with SALL4-shRNA-pRS-1 plasmid transfection complex; (4) test2 group:cells with SALL4-shRNA-pRS-2 plasmid transfection complex. The expression levels of SALL4 mRNA and protein were measured by real time fluorescence quantitative PCR and WB. C-myc, Cyclin D1 and β-catenin were important components of Wnt/β-catenin signaling pathway and their expression levels in SALL4 knockdown THP-1 cells were detected by real-time fluorescence PCR. Furthermore, THP-1 apoptosis was analyzed by flow cytometry after Annexin V-PI staining. Results Real time fluorescent quantitative PCR illustrated that the expression of SALL4 in testl group, test2 group, control group and blank group were ( 36. 0 ± 4. 3 ) %,(32. 0 ± 2. 4) %, ( 102. 0 ± 6.5 ) % and ( 100. 0 ± 2. 6 ) % respectively. There was statistical significance ( F = 226. 3, P < 0. 05 ). The expression of SALL4 in testl and test2 group respectively were significant lower than that in blank group (t = 19.7,19. 1, P<0. 05). The expression of SALL4 had no significant difference between blank group and control group (t = 1.1, P ＞0. 05). Western blot analysis revealed SALL4 protein in testl and test2 group were significantly decreased compared with those of control and blank group. All above data indicated the high efficiency of RNA interference targeting SALL4. Comparing with the blank group, the relative expression of C-myc, Cyclin D1 and β-catenin mRNA in test1, test2 and control group were(44.0 ±6.2)%,(44.0 ±5.1)% and (107.0±13.6)%;(22.0±4.5)%,(25.0±3.5)% and (48.0 ± 7. 6 ) %; ( 42.0 ± 3.5 ) %, ( 59. 0 ± 3.7 ) % and ( 79. 0 ± 5.6 ) %. The expression of C-myc,β-catenin and Cyclin D1 mRNA in testl and test2 group were significant lower than that in blank group (t = 10. 1,9. 5, 23. 3, 22. 9; 17.4, 12. 4; P < 0. 05). The percentage of apoptotic cells in group of test1,test2,control, blank were (57.2 ±9.1)%, (34.4 ±8.6)%, (14.4 ±3.6)% and (14.8 ±4.8)%respectively. There was statistical significance ( F = 42. 5, P < 0. 05 ). After the inhibition of SALL4, the percentages of apoptotic cell in testl and test2 group were significantly increased( t =9. 7, 4. 5 ;P <0. 05).Conclusion The inhibition of SALL4 in leukemia cell line THP-1 downregulates the expression of cell proliferation related genes such as C-myc, Cyclin D1,β-catenin and promoted apoptosis.

Objective To explore the capability of Ang-1 gene delivery to acute myocardial infarction using targeted microbubbles carrying ICAM-1 antibody.Methods Thirty-seven rabbits' left circumfles branch coronary arteries were ligated for models.Three rabbits were injected with microbubbles carrying ICAM-1 to detect the ability of targeting.Thirty-four rabbit models were divided into 3 groups randomly as follow:IM group (n=12,accept direct intramuscular injection),ICAM-1 group (n=12,accept intravenous injection of targeted microbubbles and Ang-1) and control group (n=10,without any treatment).Ultrasonography were executed on all animals before and 2 weeks after the treatment.All rabbits were killed after 2 weeks and examined for Ang-1 mRNA and protein by RT-PCR and Western-Blot respectively.Microvessel density (MVD) counting of infracted myocardium,observed by factor Ⅷ immunochemical staining,was performed to value the proangiogenesis effect of Ang-1 delivered by targeted microbubbles carrying ICAM-1 antibody.The liver and the kidney in ICAM-1 group were taken to assess the systemic delivery.Results IM and ICAM-1 group showed significantly improvement in the ejection fraction (P＜0.05) while control group did not.Ang-1 mRNA and protein could be detected in IM and ICAM-1 group;however,the expression between the two groups showed no siginificant difference.None of the control animals showed Ang-1 expression.compared with ICAM-1 group,the MVD was greater in IM group.Ang-1 was not detected either in liver or in kidney in ICAM-1 group.Conclusions Targeted microbubbles carrying ICAM-1 antibody can deliver Ang-1 gene to ischemic myocardium directly.Meanwhile,it's as effective as IM injections besides the greater angiogenesis effect.This strategy improves the perfusion of acute myocardial infarction and the function of heart.

Objective To investigate the transfection efficacy and expression of Ang-1 gene and proangiogenesis in vitro and vivo by ultrasound-mediated microbubble destruction.Methods 293T cells were divided into three groups:group A was given hAng-1 plasmid and microbubbles plus ultrasonic irradiation,group B was given hAng-1 plasmid and ultrasound,group C was given hAng-1 plasmid only (without ultrasound).Forty-eight hours after transfection,the transient expression rate was observed under fluorescence microscopy and flow cytometry.RT-PCR and Western blot analysis were taken to evaluate the mRNA and protein expression of Ang-1 respectively.Twenty-seven rabbit models of ligated left circumflex branch coronary artery were divided into 3 groups randomly as follow:group Ⅰ (accepted intravenous injection of SonoVue microbubble and Ang-1 plus ultrasonic irradiation),group Ⅱ (accepted intravenous injection of Ang-1 with ultrasound),group Ⅲ (control group).Myocardial contrast echocardiography (MCE) was executed on all animals before and after the treatment.Two weeks after gene delivery,RT-PCR and Western blot analysis were taken to evaluate mRNA and protein expression of Ang-1 respectively.Microvessel density (MVD) counting of infracted myocardium,observed by Factor Ⅷ immunochemical staining,was performed to value the proangiogenesis effect of Ang-1 delivered by ultrasound mediated cavitation of microbubble.Results Green fluorescence was observed in group A and B by fluorescence microscopy,which was negative in group C.The transfection expression rate was significantly improved in group A ( P ＜ 0.01).In vivo,Microbubbles could be observed in former ischemic myocardium in MCEexamination and the Ang-1 mRNA and protein could be detected in group Ⅰ.On the other hand,the contrast agent was defected obviously and none of the animals showed Ang-1 mRNA and protein expression in other two groups.The MVD counting showed significant improvement in group Ⅰ whereas other two groups didn't.ConclusionsMicrobubble-enhanced ultrasound exposure can improve the Ang-1 gene transfection expression rate observably both in vitro and in vivo.This strategy for delivering has great proangiogenesis effect in vivo.

Objective:To evaluate the value of ultrasound-guided transperineal systematic prostate biopsy(SPB)and cognitive fusion multi-parameter magnetic resonance imaging(mpMRI) suspicious transperineal targeted biopsy(CFTB) in the prostate cancer with different serum prostate specific antigen(PSA) levels.Methods:A retrospective analyses were performed in 527 patients with suspected prostate cancer who underwent ultrasound-guided SPB from January 2018 to December 2019 in Shanghai Jiaotong University Affiliated 6th People′s Hospital. According to the PSA levels, they were divided into group A(PSA 4-10 μg/L) and group B(PSA>10 μg/L). All the patients underwent ultrasound-guided SPB, 376 patients with suspicious mpMRI had two additional targeted biopsies. The detection rates of ultrasound-guided SPB and CFTB in prostate cancer were tested by χ 2 test. Compared with pathological results, the sensitivity, specificity, accuracy of two methods were calculated and tested by χ 2 test, and a P<0.05 was defined as statistically significant difference. Results:Prostate cancer was detected in 319 of 527 patients(60.5%). One hundred and three cases of 198 patients in group A were diagnosed as prostate cancer, with an overall detection rate was 52.0%. Among them, ultrasound-guided SPB detected 72 cases of prostate cancer, the detection rate was 36.4%, sensitivity was 67.9%, specificity was 17.7%, accuracy was 26.5%, the detection rate, sensitivity, specificity and accuracy of CFTB were 39.9%, 75.6%, 91.6% and 88.8%, respectively. In this group, there were no statistically significant differences in the detection rate and sensitivity of the two methods in the diagnosis of prostate cancer (χ 2=0.525, 0.005, both P>0.05), and the differences in specificity and accuracy were statistically significant (χ 2=108.340, 79.829, respectively, both P<0.05). Two hundred and sixteen cases of 329 patients in group B were diagnosed as prostate cancer, with an overall detection rate was 65.7%. Among them, 160 cases of perineal prostate cancer were detected by ultrasound-guided SPB, with the detection rate was 48.6%, sensitivity was 78.2%, specificity was 37.6% and accuracy was 49.5%. A total of 189 cases of prostate cancer detected by CFTB, the detection rate was 57.4%, the sensitivity was 89.3%, the specificity was 90.6%, and the accuracy was 90.2%. All the differences were statistically significant in group B(χ 2=5.131, 4.391, 61.339, 38.982, all P<0.05). Conclusions:When PSA is greater than 10 μg/L, CFTB has a higher diagnostic efficiency than SPB.When PSA is 4-10 μg/L, there are no significant differences between the two methods in the detection rate and sensitivity of prostate cancer.

Objective To investigate the effects of ultrasound and microbubbles on transient transfection of angiopoietin-1(Ang-1) into vascular endothelial CRL1730 cells and the effects of cell migration. Methods CRL1730 cells were divided into four groups:a control group (without any treatment), an Ang-1 group (with Ang-1 added only), a microbubble group (with only microbubbles added) and an ultrasound with microbubbles group (Ang-1, microbubbles and 1 MHz ultrasound irradiation for 30 s). All were cultivated for 24 h. The expression of Ang-1 mRNA and protein were measured using RT-PCR and Western blotting. The cells' migration ability was detected using the Transwell method. Results There was no difference in the expression of Ang-1 mRNA or protein among the control group, the Ang-1 group and the microbubbles group, but the expression of Ang-1 mRNA and protein was increased significantly in the ultrasound plus microbubbles group. Cell migration ability was also enhanced significantly in the ultrasound and microbubbles group compared with the other groups. Conclusion A combination of ultrasound and microbubbles might successfully transfect Ang-1 genes into vascular endothelial cells, and the migration ability of the transfected cells is also enhanced.

Objective To test the efficiency of gene transfer and expression mediated by ultrasound and microbubble strategy in 293T cell. Methods SonoVue microbubbles were mixed with pla.smid DNA encoding hAng-1 and green fluorescent protein. The mixture of the DNA and microbubbles was administer to cultured 293T cells by ultrasound exposue. The ultrasound condition was 1. 5 W/cm~2 and 30 s. Forty eight hours later, transfer rate was assessed by fluorescence microscopy and flow cytometry. Cell viability was assayed by Trypan Blue staining. RT-PCR and Western blot analysis was used to examine the expression of hAng-1 mRNA and protein. Agarose gel electrophoresis was used to evaluate the integrity of the plasmid. Results The transfection expression rate of eGFP in 293T cells was markedly increased with the additon of 20% microbubbles and 15 mg/L DNA. Fetal calf serum had no influence on the gene transfer rate. Ultrasound irradiation combined with microbubbles couldn't destroy the integrity of plasmid. Conclusions Ultrasound-mediated microbubbles destruction can increase the transfection and expression of hAng-1 gene in 293T.
