1.Nursing intervention in performing upper gastrointestinal longitudinal endoscopic ultrasonography
Chinese Journal of Practical Nursing 2009;25(14):54-55
Objective To investigate the effects of systematically nursing intervention on performing upper gastrointestinal longitudinal endoscopic ultrasonography. Methods From July 2006 to August 2008, 80 patients with upper gastrointestinal disease were divided into the experimental group and the control group, with 40 patients in each group. The experimental group received mental nursing before endoscopy examination, to comfort and encourage them to eliminate the psychological tension, instructing patients to relax, turning off lights to reduce the horror resulted from seeing insertion of large visual endoscopic ultrasonography into their mouths. While the control group received standard care of gastrointestinal endoscopic examination. The horror, nausea, abrasion of laryngopharynx and repeated operation were compared in the two groups using x2 test. Results The incidence of abnormal conditions in the experimental group was lower than those of the control group. Conclusions Nursing intervention can elevate the success rate of exami-nation, reduce the suffering of patients and ensure the smooth conduct of examination.
2.Research progress of genetic monitoring methods in guinea pig
Chinese Journal of Comparative Medicine 2014;(8):62-66
Guinea pig as a commonly used laboratory animal is widely used in various fields of biomedical research.The stability of genetic quality directly affects its development and application .Genetic testing is designed to confirm the genetic characteristics of each strain , to verify whether there are genetic mutations and other genetic contamination, to ensure that the test object meets the requirements of this strain .Along with the emerge of biochemical and molecular marker technology , a more convenient and reliable means is provided for research of genetic homozygosity , genetic type detection and genetic quality monitoring of guinea pigs .In this paper, the application and research progress of biochemical, cytological and molecular markers in studies of guinea pig diversity will be summarized , and provide some help for genetic testing guinea pig.
3.An update of RNA interference in tumor therapy
Journal of Medical Postgraduates 2003;0(08):-
Tumor is a reciprocity result of various genes and factors,and its incidence and mortality remain high.Such traditional strategies as surgery,radiotherapy and chemotherapy cannot completely restrain and reverse the growth of tumor cells.So,new and more effective therapeutic methods are being expected.This article updates the development of RNA interfering(RANi) technique in the targeting therapy of the tumor gene.
4.Predictors of hemorrhagic transformation after thrombolysis in patients with ischemic stroke
International Journal of Cerebrovascular Diseases 2016;24(8):734-739
Hemorrhagic transformation is a common complication after ischemic stroke, especially after thrombolytic therapy. Its disability and mortality are very high. Therefore, it limits the clinical application of thrombolytic therapy. This article reviews the types of hemorrhagic transformation, possible mechanisms and predictors after thrombolysis for ischemic stroke in order to provide reference for clinical treatment and research of ischemic stroke.

Social tagging, as an important method for organizing network resources, has been widely applied in different kinds of website with the development of Web2.0 technologies.Proposed in this paper are the suggestions for promoting the better development of healthsocial networks, such as establishing social login model, developing tag library, constructing tag automatic classification system, implementing personal recommendation system, analy -zing tag semantemes , and limiting users login rights according to the application of social tagging in health social networks and related problems needing to be solved .

0.05).Conclusion: rhGH can stimulate the growth of GHR2+ tumor cell lines such as SGC-7901 and weaken the inhibitory effect of 5-FU on GHR2+ tumor cells.However,such effect was not remarked for GHR+ tumor cells in vitro.

Objective To investigate the expression of BRCA1 in chemosensitive and chemoresistant ovarian cancer specimens,so as to provide a novel insight into the epigenetic mechanism involved in BRCA1 transcription. Methods Serous ovarian cancer patients(10 chemosensitive and 10 chemoresistant cancer)were enrolled for the study. BRCA1 levels was analyzed by real?time quantitative PCR. The methylation levels of BRCA1 core promoter(sites 1?4)was determined by pyrosequencing. Regression analysis was used to examine the possible relationship between BRCA1 levels and the methylation levels of sites 1?4 in ovarian cancer specimens. Results Compared to chemosensitive ovarian cancer tissues,BRCA1 levels were increased,but the methylation levels of BRCA1 core promoter(sites 1?4)were decreased in chemoresistant ovarian cancer tissues. How?ever,it is interesting to note that only a significant inverse correlation was observed between BRCA1 levels and the methylated levels of site 4 (r=-0.612,P<0.05). Conclusion Our findings imply that the methylation levels of site 4 in the core promoter of BRCA1 may be widely involved in the regulation of BRCA1 expression and chemosensitivity in ovarian cancer.
