AIM:To explore the effectiveness of acupuncture transcutaneous electrical nerve stimulation(Acu-TENS), a non-invasive modality in reduction of rectal discomfort during barostat-induced rectal distension. METHODS:Forty healthy subjects were randomized to receive 45 min of either Acu-TENS or placebo-TENS(no electrical output)over acupuncture points Hegu(largeintestine 4),Neiguan(pericardium 6)and Zusanli(stomach 36).A balloon catheter attached to a dual-drive barostat machine was then inserted into the subjects'rectum.A step-wise(4 mmHg)increase in balloon pressure was induced until maximal tolerable or 48 *** analogue scale and a 5-point subjective discomfort scale(no perception,first per-ception of distension,urge to defecate,discomfort/ pain and extreme pain)were used to assess rectal discomfort at each distension *** beta-endorphin levels were measured before,immediately after intervention,at 24 mmHg and at maximal toler- able distension pressure. RESULTS:There was no difference in the demographic data and baseline plasma beta-endorphin levels between the two *** threshold levels were higher in the Acu-TENS group when compared to the placebo group,but the difference reached statistical significance only at the sensations"urge to defecate"and"pain".The distension pressures recorded at the"urge to defecate"sensation for the Acu-TENS and placebo-TENS groups were 28.0±4.5 mmHg and 24.6±5.7 mmHg,respectively(P=0.043);and the pressures recorded for the"pain"sensation for these two groups were 36.0±4.2 mmHg and 30.5± 4.3 mmHg respectively(P=0.002).Compared to the placebo group,a higher number of participants in the Acu-TENS group tolerated higher distension pressures (>40 mmHg)(65%in Acu-TENS vs 25%in placebo, P=0.02).The plasma beta-endorphin levels of the Acu-TENS group were significantly higher than that of the placebo group at barostat inflation pressure of 24 mmHg(1.31±0.40 ng/mL vs 1.04±0.43 ng/mL,P= 0.044)and at maximal inflation p

Multiple comparisons among genomes can clarify their evolution, speciation, and functional innova- tions. To date, the genome sequences of eight grasses representing the most economically important Poaceae （grass） clades have been published, and their genomic-level comparison is an essential foundation for evolutionary, functional, and translational research. Using a formal and conservative approach, we aligned these genomes. Direct comparison of paralogous gene pairs all duplicated simultaneously reveal striking variation in evolutionary rates among whole genomes, with nucleotide substitution slowest in rice and up to 48% faster in other grasses, adding a new dimension to the value of rice as a grass model. We reconstructed ancestral genome contents for major evolutionary nodes, potentially contributing to understanding the divergence and speciation of grasses. Recent fossil evidence suggests revisions of the estimated dates of key evolutionary events, implying that the pan-grass polyploidization occurred ~96 million years ago and could not be related to the Creta- ceous-Tertiary mass extinction as previously inferred. Adjusted dating to reflect both updated fossil evidence and lineage-specific evolutionary rates suggested that maize subgenome divergence and maize-sorghum divergence were virtually simultaneous, a coincidence that would be explained if poly- ploidization directly contributed to speciation. This work lays a solid foundation for Poaceae transla- tional genomics.

Establishment of a Tumor-bearing Mouse Model Stably Expressing EGFP Labeled Human MUC1 VNTRs

引用

Chemical Research in Chinese Universities 2008年第4期24卷 505-510页

作者： ZHANG Shu-zi ZHANG Hai-hong ZHANG wa SHI He-liang YU Xiang-hui KONG Wei LI Wei Vaccine Research Center College of Life Science Jilin University Changchun 130012 P R. China

Two eukaryotic vectors expressing 9 tandem repeats of human MUCI（VNTR）, VR1012-VNTR, and pEGFP-VNTR, were constructed by cloning VNTR gene into VR1012 and pEGFP, respectively. VNTR stably expressing murine Lewis lung carcinoma（LLC） cell line（VNTR^＋ LLC） was established by Lipofectamine-mediated transfection of pEGFP-VNTR into LLC cells. The EGFP expression was observed under a fluorescent microscope and VNTR expression in VNTR^＋ LLC cells was confirmed by means of Western blotting. A syngenic graft tumor model was generated by subcutaneous injection of VNTR^＋ LLC cells into C57/BL6 mice and tumor size increased rapidly with time and in a cell qumber dependent manner. VNTR mRNA expression in the tumor formed was confirmed by RT-PCR. After the third immunization mice were challenged subcutaneously with 5×10^5 VNTR^＋ LLC cells, a significant reduction of subcutaneous tumor growth was observed in the groups immunized with VNTR plasmid DNA compared with that in the groups immunized with the vector DNA alone. Thus, the suppression of subcutaneous tumor was antigen-specific. This model is useful for the development of tumor vaccines targeting MUCI VNTRs.
