1.Design of medical library information service model according semantic Web and SOA
Chinese Journal of Medical Library and Information Science 2015;(9):46-49
An information service model of subject librarians was proposed according to the semantic-linked data, changing retrieval methods of ontology technology users, and ontology.This model provides an open application in-terface by making use of SOA for the semantic-based information service, establishes the expanded semantic-linked relation between resources by constructing the driving engine and knowledge database based on linked data technolo-gy, and builds subject librarian platform, medical expert platform and subject user platform.Subject librarians can thus provide intelligent information retrieval service for medical users at semantic level under the help of medical experts.

Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
This experiment has proved that bolbostemmosaponin and its constituents A and D have relatively powerful spermatocidal effects. They can kill all spermatozoa in a moment at the concentrations of 0.04%, 0.04% and 0.03% respectively. These spermatocidal agents mainly distroy the biomembrane system of sperm. Using the fixed gelatin membrane technique proved that all of them can strongly inhibit tne activity of a single sperm acrosin at the concentration of 0.05%.

Objective: To study the effect of different ratios of n-6 to n-3 polyunsaturated fatty acid on serum lipid in mice, on the premise that the ratio of SFA to MUFA to PUFA is 1∶1.7∶1.2 or 1∶1∶1. Methods: Ten experimental diets were made from six oils different in fatty acid composition to raise the mice for 10 w. Then the blood lipids were determined in mice fed with different experimental diets.

Based on the ratio of S/M/P 1∶1∶1 , n-6/n-3 at 1∶1 will have lower serum lipid level. Based on the ratio of n-6 /n-3 10∶1 which is the current dietary fatty acid composition abroad , S/M/P 1∶1.7∶1.2 will have lower serum lipid level.

AIM: To investigate the phenomenon that miR-let-7d regulates the proliferation and invasion abilities of the lung cancer cells through nuclear receptor peroxisome proliferator-activated receptors γ (PPARγ).METHODS: The relation between PPARγ and microRNA was analyzed by bioinformatics.The plasmid reporter assay was used to verify that PPARγ was the target of miR-let-7d.The lung cancer cell line with low expression of PPARγ was selected from different lung cancer cell lines by Western blot.The regulatory role of miR-let-7d in the lung cancer cells was determined by dual luciferase labeling and Western blot.The effect of miR-let-7d on the proliferation ability of lung cancer cells was detected by colony formation assay, the effect of miR-let-7d on the invasive ability of lung cancer cells was detected by Transwell invasion assay.RESULTS: The results of bioinformatic analysis showed that miR-let-7d regulated the expression of PPARγ, and the 3'UTR of PPARγ contained 2 functional miR-let-7d binding sites, indicating that PPARγ is a direct target of miR-let-7d.miR-let-7d was able to directly regulate the expression of PPARγ at mRNA and protein levels.Transfection of miR-let-7d inhibitor promoted the proliferation and invasion abilities of lung cancer cells by increasing the expression of PPARγ.CONCLUSION: miR-let-7d increases the expression of tumor suppressor PPARγ to inhibit the proliferation and invasive abilities of lung cancer cells.

ObjectiveTo study the anti-proliferative effect and the mechanism of arotinoid Ro40-8757 on human pancreatic carcinoma cell line JF-305.MethodsMTT assay was used to evaluate the growth inhibition effect of Ro40-8757 on human pancreatic carcinoma cell line JF-305. The expression of p27 protein was measured by Western blotting, and flow cytometry for cell cycle analysis.ResultsRo40-8757 significantly inhibited the growth of JF-305 cells with a dose-, time-dependent manner. After 72 hours treatment with 10 -5mol/L Ro40-8757, the proportion of cells in G 1 phase increased from 56% to 76% while the cells in S phase decreased from 25% to 7%. Western blot analysis showed that the expression of p27 protein in cells treated with Ro40-8757 increased markedly.Conclusion Ro40-8757 inhibits the growth of pancreatic carcinoma cell line JF-305 possibly by up-regulating p27 protein expression and arresting cell cycle.

Objective To understand the characteristics of surface electromyography (sEMG)of vastus medialis muscle fatigue induced by isokinetic flexion and extension movement, and to further provide references for the application of sEMG on dynamical movements.Methods Arial isokinetic equipment and ME6000 equipment were combined to analyze the time domain indices including root mean square (RMS ) integrated electromyography (iEMG)and spectrum indices including median frequency (MF)and mean power frequency (MPF)for vastus medialis from ten students from Shenyang Sport University during isokinetic fatigue.Results During the isokinetic muscle fatigue the RMS and iEMG were significantly increased (P<0.05),accompanying with higher effect sizes for iEMG than for RMS. As for the spectrum indices,MF and MPF were significantly decreased (P<0.05)with larger effect sizes for MPF than for MF. The increase rate of iEMG was significantly higher in iEMG than RMS (P<0.05),and the decline rate of MPF was larger than MF (P<0.05).Conclusion The iEMG as a time domain index and MPF as a spectrum index can be sensitive indexes to assess the dynamic muscle fatigue.
