Objective To investigate the permeability changes of prostate cancer cells membrane under low intensity ultrasound in vitro.Methods The culture of monolayer adherent LNCaP prostate cancer cells in six-well plate was exposed to continuous ultrasound at frequency of 1 MHz.The cells membrane permeability (stained with Calcein)and cells viability(stained with PI)were evaluated by fluorescent microscope (FM) and cells morphological changes were evaluated by scanning electron microscope (SEM) under ultrasound with acoustic intensity of 160 mW/cm2 for 5 s.The rate of cells with increased cells membrane permeability as function of acoustic intensity (80 mW/cm2,120 mW/cm2 and 160 mW/cm2,for 5 s) and exposure duration (5 s,10 s and 15 s,acoustic intensity of 120 mW/cm2) was evaluated by flow cytometry.ResultsAfter low intensity of ultrasound,the cells with increased cell membrane permeability could be clearly shown with Calcein uptake under FM while no cell showed Calcein uptake in the control group.The SEM showed less microvilli on the cells after low intensity of ultrasound exposure and few cells showed holes on the cell membrane.The rate of cells with increased membrane permeability increased with acoustic intensity and exposure duration.Conclusion Low intensity ultrasound alone could increase membrane permeability of prostate cancer cells and cells with increased membrane permeability showed surface plane,uncommon holes on the cells membrane.The rate of cells with increased membrane permeability positively correlated with acoustic intensity and exposure duration.

OBJECTIVE:To improve rational drug use and reduce potentially inappropriate medication (PIM). METHODS:PIM of 700 elderly inpatients in internal medicine department of our hospital was evaluated by Beers criteria(2012 edition)and STOPP/START criteria. RESULTS:700 inpatients whose mean ages were (76.3 ± 7.2) years old took (12.1 ± 4.9) kinds of drugs per patient. 144 cases involved PIM(20.6%). The number of PIM was 220 in total,among which there were 117 cases/times relat-ed to drugs and 22 cases/times related to disease in according to Beers criteria,9 cases/times of STOPP and 72 cases/times of START. Drug with most frequency of PIM in accordance with Beers was benzodiazepines and most frequency in STOPP was thia-zides that used by patients with gout histonry. The most omission frequency of START prescription were absence of metformin thera-py for type 2 diabetes and absence of antiplatelet therapy for diabetes complicated with cardiovascular risk. CONCLUSIONS:A high prevalence of PIM in elderly inpatients in our hospital requires various measures to prevent its occurrence.

The effects of E-cadherin-transfected neural stem cells (NSCs) transplantation for spinal cord injury (SCI) in rats were investigated. Sixty SD rats were randomly divided into model control group, NSCs group, empty plasmid group and E-cadherin overexpression group (n=15 each). The animal SCI model was established by using the modified Allen's method. NSCs were cultured. Rats in NSCs group were subjected to NSCs transplantation. E-cadherin gene eucaryotic expression vector and pcDNA3.1-E-cadherin were respectively transfected into cultured NSCs, serving as empty plasmid group and E-cadherin overexpression group respectively. At 7th day after transplantation, neurological function of all rats was assessed by Tarlov score. After rats were sacrificed in each group, the number of BrdU and Nestin positive cells was counted by immunohistochemistry. Immumofluorescence method was used to detect the expression of neurofilament protein (NF) and glial fibrillary acidic protein (GFAP). As compared with model control group, the Tarlov score and the number of of BrdU and Nestin positive cells, and the expression of NF and GFAP in NSCs group, empty plasmid group, and E-cadherin overexpression group were increased significantly (P<0.05), and those in the E-cadherin overexpression group were increased more significantly than the other transplantation groups (P<0.05). It was suggested that E-cadherin could be conductive to nerve regeneration and repair probably by promoting the proliferation and differentiation of NSCs.
