RNA dot blot hybridization was employed to investigate the alterations in C-myc, C-H-ras transcript levels in bone marrow and peripheral blood cells from 24 patients with acute nonlymphocytic leukemia. 10 cases of normal bone marrow cells were used as control. We found that the positive rates and intensities of expression of C-myc and C-H-ras in acute nonlymphocytic leukemia were hipher than those of normal control. The C-myc and C-H-ras expressed simultaneously in 10 patients. After having been cultured 5 days with RA and low dose Ara-C combined with low dose Harr, the C-myc transcipt level of C-myc in acute nonlymphocytic leukemia was decreased obviously.

In this article,the purpose,period,overview,and principle of medical subject headings renovation was introduced,to provide references for national headings renovation and maintenance.

Medical subject headings (MeSH) was compiled by American state-run medical library.In this article,the update maintenance,data publication,technological support,and management of human and finical resources on MeSH were introduced.

This paper is intended to figure out how to develop and maintain the traditional Chinese medical (TCM)thesaurus in the Internet Era. The history of TCM thesaurus was reviewed. The function of TCM thesaurus in searching information in internet and the impact of internet to thesauri were discussed. Suggestions on descriptor/term selection, term relations, and thesaurus maintaining were put forward.

Nowadays,with the rapid development of science and technology of medicine,the detection rate of obstructivc azoospermia increased gradually,clinically not uncommon.Surgical treatment of obstructive azoospermia is also improved from traditional vasovasostomy and epididymovasostomy to microsurgical vasovasos-tomy and microsurgical va-soepididymostomy,and from 3-suture intussusception vasoepididymostomy to 2-suture intussusception vasoepididymostomy,then our modified reverse single needle anastomosis,and finally to the robot assisted anastomosis.Therefore,the anastomosis is more precise,the recanalization rate and the pregnancy rate have a revolutionary improvement.The robot era is coming.The article focuses on surgical treatment of obstructive azoospermia,comparison of the advantages and disadvantages of each operation,and prediction of the future direction of development.

An overview was performed on the features, structure, included terms, applications and the process of editing and compiling of traditional Chinese medical thesaurus and its relative thesaurus.

To solve the calibration transmission problem in near-infrared ( NIR) spectroscopy, a novel model transfer method, Simple Linear Regression Direct Standard-ization ( SLRDS ) , has been presented. To investigate the validity of the proposed method, a real corn sample NIR dataset was tested and the direct standardization ( DS ) method and piecewise direct standardization ( PDS ) method were involved as a comparison. Our results indicated that SLRDS can correct compressed NIR data differences among instruments and enable the user to share corn sample PLS calibration model among three instruments, at the same time it has higher prediction accuracy, fewer parameters and simpler model than DS and PDS.

Objective To explore the effect of motor imagery on motor recovery in hemiplegic patients after stroke. Methods From May, 2015 to October, 2016, 40 hemiplegic patients after stroke were randomly divided into control group (accepted routine rehabilitation, n=20) and motor imagery group (accepted motor imagery and routine rehabilitation, n=20). They were assessed with Fugl-Meyer Assess-ment (FMA), modified Barthel Index (MBI) before and six weeks after treatment. Fractional anisotropy (FA) of the focus was measured with diffusion tensor imaging (DTI). Results The scores of FMA and MBI improved in both groups after treatment (t>5.088, P<0.001), and improved more in the motor imagery group than in the control group (t>2.124, P<0.05). The FA reduced in the focus compared with the same site of unaffected side in both groups before treatment (t>3.892, P<0.01), and there was no significant difference between two groups (t<1.144, P>0.05). FA increased in more patients of the motor imagery group (5/5) than in the control group (2/4). Conclusion Motor imag-ery can promote the recovery of motor function and activities of daily living in stroke patients, and may help the recovery of fibers in white matter.

Objective To test whether feeder cells derived from mouse embryonic stem cells(mESCs) could support the growth of mESCs themselves. Methods mESCs were induced to form mouse embryoid bodies(EB),and then fibroblast-like cells were derived from further differentiated mEB(mEB-dF),which served as feeder cells.The undifferentiation of mESCs grown on mEB-dF was confirmed by morphological analysis,colony efficiency and cell differentiation rate of mESCs,immunocytochemistry,alkaline phosphatase staining and RT-PCR.The pluripotency of mESCs grown on mEB-dF was examined by RT-PCR,inducing their differentiation in vivo and in vitro. Results(Forty-eight) fibroblast-like cells lines were derived from the same EB at three periods(d 10,d 15 and d 20),and five of them,mostly derived from d15 EB,were able to maintain mESCs in undifferentiated status and pluripotential ability over 10 passages.mESCs cultured on these feeder cell lines expressed alkaline phosphatase and specific mESCs markers,including SSEA-1,OCT-4,NANOG,and formed EB in vitro and teratomas in vivo.However,the majority of mEB-dF lines(43/48) has no such ability. Conclusion This study not only provides a novel feeder system for mESCs culture,avoiding lot of disadvantages of mouse embryo fibroblasts used as the feeder,but also indicates that fibroblast-like cells derived from mESCs take on different functions.The molecular mechanism of different function of these fibroblast cells is worthy of further investigations.
