Objective:Toconstruct the shRNA(Short Hairpin RNA)eukaryotic expression vector targetingat IER3IP1 gene and observe its silencing effect on IER3IP1 gene.Methods:Two pairs of DNA fragments targeting at IER3IP1 gene and one pair of DNA fragment of negative control were synthesized and cloned into the Eukaryotic Expression Vector pGenesil-1.These vectors were separately transfected into the L02 cells.Inhibitory effect at the time of 24,48,72 h after transfection were detected by semiquantitative RT-PCR.Results:These shRNA eukaryotic expression vectors were successfully constructed.One of them could significantly and specially inhibite the expression of IER3IP1 gene and the inhibition ratios were separately 64%,79%and 69%at the time of 24,48 and 72 h,compared with empty vector group.Conclusion:The combinated eukaryotic expression vector could inhibit the expression of IER3IP1 gene,which forms the basis for investigating IER3IP1 gene's function.

Objective To explore the correlation of urine albumin and creatinine ratio(UACR)and short -term prognosis in patients with acute ischemic stroke (AIS).Methods 112 patients with AIS were selected as the research subjects.The admission UACR and related laboratory examination indexes were detected,the US national institutes of health stroke scale (NIHSS)scores,and 28 d after admission of the modified Rankin scale (mRS) prognostic score were recorded.The NIHSS 5 or more points and NIHSS <5 points,different levels and UACR patient observation index between the different prognosis group were compared.Results NIHSS 5 or more group of patients on admission UACR level[(15.41 ±3.21 mg/g)]was higher than the NIHSS <5 patients (9.52 ±2.04)mg/g (t =12.214,P <0.001);UACR acuity 11.60mg/g group in NIHSS of 5 or more proportion of patients (87.5%),mRS score >2 points (82.1%),the proportion of the recent death patients (23.2%)than the proportion of UACR <11.60mg/g,the proportion of the group (32.1%,25.0%,7.1%;the chi -square values 33.509,34.476,5.598,all P <0.050);MRS score >2 groups of patients UACR level[(16.10 ±3.29)mg/g]was higher than that in patients with mRS score 2 points or less (8.38 ±1.95)mg/g(t =20.132,P <0.001);Pearson correlation analysis showed that the standard of UACR and NIHSS score (r =0.412,P <0.05 ),high -sensitivity C -reactive protein (hs -CRP)(r =0.473,P <0.050),white blood cell count (WBC)(r =0.442,P <0.050),fasting plasma glucose (FPG)(r =0.375,P <0.050)were positively correlated.Multiariable Logistic regression analysis showed that UACR (OR =1.587,P <0.050)was a recent independent risk factors of poor prognosis in patients with AIS. Conclusion UACR the illness severity and recent prognosis of patients with AIS is closely related to high levels of UACR may be recent independent risk factors of poor prognosis in patients with AIS.

Objective To mine the relation between leukemia and genes using Weka. Methods The papers on leuke-mia and genes were retrieved from PubMed, their subject headings and subheadings were extracted using BICOMB to generate co-occurrence matrix and term-paper matrix. The research hotspots were found by cluster analysis of the data on co-occurrence matrix using Weka and Cobweb. The literature was verified. Results The 42 high fre-quency words were clustered into 7 classes by Weka. No high frequency words of leukemia or genes were found in classes 1, 2, 4 and 5, indicating that their clustering efficiency was poor. The clustering efficiency of the other 3 classes was good. Conclusion Cluster analysis showed that leukemia is related with myc gene, ab1 gene, p53 gene, virus gene, immunoglobulin gene and mdm gene.

OBJECTIVE:To discuss the issue of how to take advantage of intellectual property law to promote the sus?tainable development of our traditional Chinese medicine,and to establish the related legal system to protect the intellectual property of traditional Chinese medicine.METHODS:On the basis of literature review,the necessity and foundation of establishing distinctive protective law on traditional Chinese medicine were discussed.RESULT:There were internationally precedents of legislation on biodiversity and cultural diversity;Neither“Trade-Related Aspects of Intellectual Property Rights”nor other WTO files forbad individual country to establish its own policy according to its specific situation,however,these policies should not be against the fundamental principle of WTO;Moreover,foreign countries is paying much more at?tention on legislation of traditional Chinese medicine and herb than they used to.DISCUSSION:It is of great necessity to establish the distinctive protective law on traditional Chinese medicine,which can best be enforced by promoting the self de?velopment of traditional Chinese medicine,especially the investment and innovation in this field.

Objective To detect normal rat jejunum epithelial cells to learn about the distribution of peptide YY(PYY)receptor and measured two important parameters of PYY receptor so as to explore the target that PYY binds to and display its physiological function.Methods Receptor radioligand assay was conducted by using 125I-PYY to detect normal rat jejunum epithelial cells.We also measured receptor dissociation constant(Kd),the affinity or the ability that the receptor could bind ligand;maximum binding capacity(Bmax),the concentration of binding site;and Hill coefficient.Results There were PYY receptors in normal rat jejunum epithelial cells.Dissociation constant(Kd)of PYY receptor was(386.69?129.95)pmol/L.Maximum binding capacity(Bmax)was(303.21?116.85)fmol/mg protein.Hill coefficient was 1.PYY receptor had high affinity.Conclusion There are distributions of PYY receptors in normal rat jejunum epithelial cells.Kd means that PYY receptor has high affinity.Bmax means that the number of receptors is limited and decides the characters of saturability.We think that PYY directly inhibits secretion by binding to PYY receptor in jejunum epithelial cells when PYY inhibiting jejunum secretion.

As the implementation of national policy which calls for college graduates to work in grassroots posts,it is one of the key and urgent issues in current college employment task to guide and encourage college graduates to work in grassroots posts.By investigating the bachelor graduates' attitude towards working in grassroots posts in Shenyang medical college and analyzing the investigation data,this paper points out influential factors of medical graduates' selection of employment,and comes up with positive and effective countermeasures to promote the grassroots employment of medical graduates.

Young faculty are an essential part of a university's strength and is important for its sustainable development.And their scientific research capability is associated with the long-term development of the university.At present,there are 4 major problems with the development of young faculty's research capabilities,which include their relatively single academic knowledge structure,insufficient experience in writing proposals,insufficient opportunities for academic exchange,and inequity in resource allocation.Establishing a training mechanism may help solve some of the problems and promot their development.The research management department of a university must abandon erroneous traditional management concepts,provide research training seminars,develop a new mechanism to stimulate academic exchange,design a system for short-term laboratory rotations,and promote the participation of your faculty in major research projects.These may bring about marked improvement in the improvement of young faculty's research capabilities.

Embodied as an abstract concept as well as concrete regulations and material environment on the campus,the campus culture is the organizational culture among universities,which plays a significant role in enhancing students' quality of career starting.Similar to its social culture,the American campus culture is characterized by a strong personal heroism thus is known as a "cowboy culture".As the so-called "dragon culture",the Chinese culture is a more conservative one and thus lack of innovation-oriented career starting concepts among Chinese university students.Therefore,in order to effectively carry out entrepreneurship education in colleges and universities,the innovation-oriented campus culture should be constructed,students' entrepreneurship conception strengthened,thus students' sense of career starting and mental status be enhanced.
