Tumor 2007;27(11):857-860
Objective: To study the molecular mechanism underlying androgen-independent prostate cancer invasion and metastasis promoted by vimentin. Methods: With specific amplified primer of vimentin, full-length vimentin and full-length antisense-vimentin cDNA fragments were synthesized by reverse transcriptase polymerase chain reaction ( RT-PCR). RT-PCR products were cloned into plasmid pcDNA3.1 (+) and pcDNA3.1 (-). The recombinant vimentin plasmids were transfected into androgen-independent prostate cancer PC-3M-2B4 and PC-3M-1E8 cells. The positive clones were screened by G418. The transwell chamber migration assay was used to study cell invasion. Western blotting was used to determine specific protein expression in the cells. Results: Vimentin promoted androgen-independent prostate cancer cell invasion and metastasis by regulating the E-cadherin/β-catenin complex via C-src kinase. Conclusion: Vimentin could be used as an important prognostic factor for androgen-independent prostate cancer cell invasion and metastasis.

Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

Objective To analyze risk factors for surgical site infection(SSI) in cardiac surgery patients,so as to provide basis for making control measures.Methods 215 patients who underwent cardiac surgery in a hospital between January 2012 to December 2014 were investigated,univariate analysis and multivariate logistic regression analysis were used to analyze the related risk factors for postoperative SSI.Results The incidence of postoperative SSI in cardiac surgery patients was 16.28% (35/215).Univariate analysis showed that the incidence of postoperative SSI was relatively higher in patients aged>65 years,duration of operation>5 hours,continuous operation,preoperative hospitalization time >7 days,irrational perioperative antimicrobial use,as well as patients with underlying diseases such as hypertension and diabetes mellitus.Multivariate logistic regression analysis indicated that the age,duration of operation,continuous operation,preoperative hospitalization time,irrational perioperative use of antimicrobial agents,and patients with underlying diseases were independent risk factors for SSI in patients who underwent cardiac surgery.Conclusion Incidence of SSI is higher in patients with cardiac surgery,preventive measures should be taken to control risk factors such as duration of operation,so as to reduce the incidence of SSI.
