Objective To detect differentially expressed genes in prostate cancer by cDNA microarray. Methods Total RNA was isolated by one step protocol from prostate cancer (CaP) and from normal prostate,and Poly(A) +RNA was further purified through Oligitex mRNA Midi Kit.Then it was analysed for differentially expressed genes in CaP and normal prostate by cDNA microarray with 4 096 human genes. Results There were 341 differentially expressed genes between CaP and normal prostate,of which there were 128 down regulated and 213 up regulated ones for CaP. Among these genes,15 were the most significant with 6 down regulated and 9 up regulated. Conclusions cDNA microarray can be used effectively to find out differentially expressed genes in prostate cancer which is not regulated by any single gene.Many different kinds of genes are involved in the initiation and evolution of CaP carcinogenisis.

Objective To investigate the expression of E-cadherin in prostate cancer and its relationship with PSA. Methods E-cadherin expression of 56 prostate cancer samples were studied by immunohistochemical stain and its expression level was analyzed with respect to T-PSA, F-PSA and F/T ratio. Results 24 patients (43%) were normal and 32 patients (57%) were aberrant in E-cadherin expression. E-cadherin was related significantly to the grade and stage of cancer and the changes of F/T ratio.There were no significant relationship between E-cadherin expression and T-PSA or F-PSA. Conclusions E-cadherin expression may act as a marker to the malignant degree and the prognosis of the prostate cancer.

AIM:To determine the effect of rhBMP2 on the migration of human breast cancer cells MCF-7. METHODS:MCF-7 was induced by rhBMP2 (30 ?g/L) for 24 h. Atomic force microscopy (AFM) was used to observe the changes in cell morphology. Cell migration and invasion abilities were assayed by scratch healing and transwell experiments. RESULTS:The formation of lamellipodia and cell polarity together with increased cell length were observed in the cells treated with rhBMP2,whereas lamellipodia of cells in control group were not obvious and the majority of cells tended to be rounder with shorter cell diameter. Compared to control group,scratch healing and transwell experiments showed that the migration and invasion capacity of rhBMP2-induced MCF-7 cells was markedly enhanced. CONCLUSION:rhBMP2 induces human breast cancer cell MCF-7 to present the phenotype of migration and enhances the invasion capacity.

Objective To discuss the artery effects of enhanced external counterpulsation for the progressive stroke patients.Methods Ninety-two progressive stroke patients who were treated in the Fourth People's Hospital of Shenzhen from August 2010 to February 2015 were selected and equally divided into the treatment group and the control group based on the random number table.The control group were received conventional therapy,and the treatment group were added treated with enhanced extemal counterpulsation therapy.Results All patients were successfully completed treatment,the C-reactive protein (CRP) and Endothelin-1 (ET-1) were presented decreased significantly after treatment (P＜ 0.05),and the C RP and ET-1 values in the treatment group were (2.09±2.11) mg/L,(13.98±6.30) mg/L,significantly lower than those of the control group((8.12±2.46) mg/L,(46.09± 11.02) mg/L;t =15.309,14.985;P＜0.05).After treatment,the FMD and NMD values in the treatment group were significantly increased from (5.26±1.34)％ to (11.93 ±2.13) ％,and from (13.20±5.33)％ to (22.98±8.34)％,in the control groupand were from (5.27±1.33)％ to (8.10±1.43) ％,and from (13.67±4.10)％ to (16.09±5.12)％ (t=16.934,21.787,8.443,12.345;P ＜0.05),and the value of FMD and NMD in treatment group were significantly higher than in the control group(t =7.982,9.113;P ＜ 0.05).The cardio ankle vascular index (CAVI) and brachial ankle pulse wave velocity (baPWV) values in the treatment group were significantly reduced after treatment,the difference was significant (P＜0.05),and compared with the control group the difference was also statistically significant (t =4.281,8.456;P＜ 0.05).Conclusion Enhanced external counterpulsation for the progressive stroke patients can effectively inhibit the expression of endothelin and inflammatory factors,improve endothelium-dependent relaxation of blood vessels,improve arterial elasticity,and thus play more effective treatment.

Objectives To examine the effects of enhanced external counterpulsation on arterial elasticity in stroke patients to provide clinical evidence for secondary prevention of patients with cerebral ischemic stroke. Methods Total 192 patients with ischemic stroke were enrolled and then divided into the EECP (n=107) and control (n=85) group. Auto-matic measurement synchronous atherosclerosis detector was use to measure brachial-ankle pulse wave velocity (BaP-WV) and cardio-ankle vascular index (CAVI). The difference of BaPWV and CAVI were evaluated before, at 36 hours and one month after EECP. Results The BaPWV and CAVI significantly decreased at 36 hours and 1 month after treat-ment in EECP groups compared to either pre-therapy or control groups (all P<0.05). Conclusions EECP can signifi-cantly reduce the BaPWV and CAVI and improve the arterial elasticity in patients with cerebral ischemic stroke. Thus, arterial elasticity may be an important index to evaluate the effects of EECP on cerebral ischemic stroke.
