OBJECTIVE:To study in vitro anticancer activity of conjugated linoleic acid-gemcitabine conjugate (CLA-GEM). METHODS:IC50 of different tumor cells (breast cancer MCF-7 cell,breast cancer MDA-MB-231 cell,lung cancer A549 cell, small cell lung cancer NCI-H446 cell,glioma C6 cell)were investigated after treated with different concentrations(0.001-100μmol/L)of CLA-GEM and gemcitabine(GEM)for 72 h;survival rates of MCF-7 cell were investigated after treated with above so-lution for 24,48 and 72 h. The dependence of 0.001-100 μmol/L CLA-GEM and GEM to nucleoside transporter was investigated (by IC50)through MCF-7 cells and MDA-MB-231 cells treated with nucleoside transporter inhibitors(NBMPR,100 μmol/L)and di-pyridamole(4 μg/ml). The change of MCF-7 cell cycle was investigated after treated with 1 μmol/L CLA-GEM and GEM for 24 h. RESULTS:Compared with GEM,IC50 of MCF-7,MDA-MB-231 and NCI-H446 cells became lower after treated with CLA- GEM (P<0.01),there were no statistical significances in IC50 between A549 and C6 cells(P>0.05). Survival rate of MCF-7 cells de-creased significantly after treated with GEM for 48 h and CLA-GEM for 24 h. Survival rate of MCF-7 cells was the lowest,being 21% after treated with GEM for 72 h,while tumor cells were sacrificed by CLA-GEM completely. Compared with GEM or CLA-GEM,IC50 of MCF-7 and MDA-MB-231 cells increased significantly after treated with NBMPR,dipyridamole combined with GEM (P<0.01);there were no statistical significance in IC50 after treated with NBMPR,dipyridamole combined with CLA-GEM (P>0.05). Compared with GEM,CLA-GEM could prolong 6% of S stage of MCF-7 cells (P<0.01). CONCLU-SIONS:Compared with GEM,CLA-GEM exhibits significant antitumor activity and rapid action,and it isn’t influenced by nucle-ic acid transportation.

Objectives To investigate the mechanism of integron mediated resistance and multidrug-resistance in P.aeruginosa.Methods The variable region of integron was amplified by integron PCR.Restriction fragment length polymorphism(RFLP)and DNA sequencing were used to investigate the resistance genes in the variable region of integron.Results Of the 98 strains 35(35.7%)were the variable region positive,and size of the amplicons ranged from 1.0 kb to 4.0 kb.A total of 6 different cassette arrays were detected,including genes coding resistance to aminoglycosides,?-lactam compounds and sulfanilamides.Of the 5 cassette arrays 3 were novel,including aadA6-orfD,aadB-blaP1 and aadB-aac6-Ⅱ-blaCARB-8,and the Genbank numbers were DQ 091179,DQ 141316 and DQ 288251 respectively.Conclusions Integron mediates the resistance and multidrug resistance in P.aeruginosa.The majority of the genes located in integrons are those coding resistance to aminoglycosides.Three strains of class I integron with novel cassette arrays are reported.

Objective To investigate the effects of rhubarb extracts, i.e. rhein and emodin, on the neuronal hyperexcitability and synaptic transmission, and to further reveal the mechanism of the secondary brain damage. Methods The fluid percussion injury (FPI) rat model and extracellular recording method were used. The evoked field potentials by stimulating Schaffer collaterals were collected from the ipsilateral (impact side) and the contralateral hippocampal CA1 areas of rat in vitro. And the field potentials, including the field excitatory postsynaptic potential and the population spike, were analyzed. Results After the impact was performed on the rat parietal cortex, the evoked field potentials in the ipsilateral hippocampus CA1 area were enhanced obviously. Rhubarb extracts reduced the slope of the field excitatory postsynaptic potential and the number of the population spike significantly while rhein and emodin increased the latency of the population spike obviously. Conclusion Rhubarb extracts, i.e. rhein and emodin, can depress the neuronal hyperexcitability, which suggests that rhein and emodin play an important role in protecting the central nervous system from neuronal damage after traumatic brain injury. FPI produces hyperexcitability of hippocampal CA1 neurons, probably by enhancing excitatory synaptic transmission.

Objective:To explore the effect of virtual reality (VR)-based baduanjin exercise on the cognition, physical functioning and life quality of elderly persons with mild cognitive impairment (MCI).Methods:Fifty-seven mildly impaired elderly persons were randomly divided into an observation group ( n=29) and a control group ( n=28). Both groups were given routine care and health education in their nursing homes, while the observation group additionally performed 50 minutes of VR baduanjin exercise three times a week for 24 weeks. Both groups were assessed using the Montreal cognitive assessment (MoCA), the Rivermead behavioural memory test (second edition) (RBMT-Ⅱ), a digit-symbol substitution test (DSST) and the Trail Making Test (TMT). The short physical performance battery (SPPB) and Alzheimer′s disease quality of life (QOL-AD) instrument were also administered before and after the 24-week intervention. Results:After the intervention the average MoCA, RBMT-Ⅱ, DSST, TMT-A, SPPB and QOL-AD results of the observation group were all significantly better than before the intervention and better than the control group′s averages. The observation group also performed better on the 5 times sit-to-stand test, the tandem standing test and a walking speed test after the intervention.Conclusions:VR-based baduanjin practice can effectively improve the cognition and physical functioning of mildly impaired elderly persons, as well as improving their quality of life.

Objective To identify the species of cultured cells and to detect inter-species cross contamination by polymerase chain reaction (PCR).Methods From references and NCBI database,we outsourced 32 pairs of species-specific primers targeted to genomic DNA of ten common species of cultured cells.Then we screened for optional primers with high specificity and high sensitivity.PCR amplification with these primers,the genomic DNAs isolated from the tested cell line and agarose gel electrophoresis of the PCR products were done.Mixed DNA of 10 species was used as positive-control template,and water as negative-control template.Results Ten pairs of species-specific and highly sensitive primers were selected.By PCR amplification with these primers and agarose gel electrophoresis,we may easily identify the origin of cell lines and find whether the tested cell lines are contaminated by cells of other species.Conclusion This PCR assay provides a simple,rapid,sensitive,and cost-effective method to identify cell species and detect interspecies cross-contamination.
