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 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.

[Abstract ] Tumor, with its high morbidity and mortality, has been gained increasingly high attention from the world .Current-ly, the main treatment for solid tumor is still surgical resection , during which surgery , anesthesia and other factors may have such side effects as releasing tumor cells into blood , lymphatic , bone marrow even organs and then resulting in the formation of micrometastatic lesion, increasing the risk of tumor recurrence and metastasis and finally affecting the postoperative survival rate .Recently, studies have shown that most anesthetic agents can influence the function of immune system and the activity of tumor cells , and then impact the tumor micrometastasis .This paper will summarize the research progresses in the impacts of anesthetic agents on tumor micrometastasis during perioperative period .

Objective To study and explore Glucose-reducing effect of induced human bone mes-enchymal stem cells on diabetic mice.Methods The diabetic model of rats was duplicated by injection of STZ intraperitoneally.The induced cells were implanted into diabetic mice.Blood glucose levels were moni-tored every 3 days after implantation for 14 days.Results The mice receiving the treated Cells began to decrease their blood glucose levels after 3days.But control Animals that did not receive induced cells exhib-ited persistent hyperglycemia.Conclusions Induced cells by hBMSCs can decrease blood glucose levels on diabetic mice.

ObjectiveTo observe the clinical efficacy of warming-unblocking Yin Heel Vessel plus rehabilitation training in treating post-stroke strephenopodia, for seeking the optimal treatment protocol.MethodNinety eligible subjects withpost-stroke strephenopodia were randomized into an acupuncture group, a rehabilitation group, and a united group, to respectively receive warming-unblocking Yin Heel Vessel, rehabilitation treatment, and warming-unblocking Yin Heel Vessel plus rehabilitation training. ResultTwo treatment courses later, there was no significant difference in comparing the strephenopodia score between the acupuncture group and rehabilitation group (P>0.05); the strephenopodia score in the united group was significantly different from that in the acupuncture group and rehabilitation group (P<0.05), and the improvement in strephenopodia in the united group was superior to that in both acupuncture group and rehabilitation group.ConclusionWarming-unblocking Yin Heel Vessel plus rehabilitation can produce a content efficacy in treating post-stroke strephenopodia.

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.

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.

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.

To observe the pathological changes of vascular aging in spontaneously hypertensive rats (SHRs), and the effects of extracts from Panax ginseng, Panax notoginseng (Burk.) and Ligusticum chuanxiong on vascular aging.

ObjectiveTo explore the effect of Songlingxuemaikang combined with losartan on the blood pressure and quality of life in female patients with menopausal hypertension.Methods87 female patients with menopausal hypertension were randomly divided into combined group (Songlingxuemaikang combined with losartan group,44 cases) and the control group(losartan alone,43 cases).Before and after treatment the ambulatory blood pressure (ABMP) was monitored for 24h,and blood lipids and clinical symptoms were observed.ResultsAfter two months treatment,the blood pressure variability and nighttime blood pressure decrease rate of the combination group significantly reduced,and better than those of the control group( all P ＜0.05) ;The effective rate and efficiency rate of the combination group were 90.9％,63.6％ respectively,and was higher than 74.4％,39.5％ in the control group( x2 =4.15,5.06,all P ＜ 0.05 ).The clinical symptoms improving,total cholesterol ( TC ) reducing,density lipoprotein (LDL-C) lowing in the combination group was superior to the control group( all P ＜ 0.05).ConclusionSonglingxuemaikang combined with losartan in treatment of female patients with menopausal hypertension had a good antihypertensive effect,and could reduce blood pressure variability in menopausal women,improve the symptoms of menopause and lipid metabolism,incresse the quality of lfie of patients with menopausal hypertensive.
