1.Progress on DAB2IP gene
Chinese Journal of Pathophysiology 2011;27(7):1445-1449
Human DAB2 interaction protein (DAB2IP) is a novel member of Ras GTPase-activating protein family. It interacts directly with disabled-2 protein (DAB2/DOC2) which suppresses growth of cancers derived from different tissues, including mammary, prostate and ovarian cancers. DAB2IP was identified as an immediate downstream effector mediated by DAB2/DOC2. DAB2IP and DAB2/DOC2 form a unique protein complex that has a negative regulatory effect on the Ras-mediated signal pathway. It is demonstrated that DAB2IP is a tumor suppressor gene inactivated by methylation in several cancers. This article reviews the structure and biological functions of DAB2IP gene as well as its potential roles in carcinogenesis and evolution.
2.Distribution and characters of peptide YY receptor in rat jejunum epithelial cell
Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(01):-
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.
3.Visual electrophysiological abnormality in patients with pregnancy-induced hypertension syndrome
Recent Advances in Ophthalmology 2000;20(5):328-330
Objective To study the visual electrophyological changes in patients with pregnancy-induced hypertension syndrome(PIH).Methods The visual evoked potentials (VEP) and electroretinogram (ERG) of 28 patients with PIH in 56 eyes were recorded.Results The patients with PIH had pathologic visual electrophysiologic abnormalities. The VEP N75 peak latency significantly increased(P<0.05), and the ERG b wave latency in patients with PIH showed remarkable difference(P<0.05).Conclusion Visual electrophysiological examination may be valuable in early diagnosis of retinal disfunction in patients with PIH.
4.Construction of the Chinese cancer-related fatigue assessment scale by using Delphi technique
Chinese Journal of Practical Nursing 2009;25(35):11-14
Objective To construct the Chinese cancer-related fatigue assessment tool by using Delphi technique.Methods A certain number of expels were chosen for consulting to form a consuiting scale.Two-round consultations were conducted and the results were analyzed.Results The Chinese cancer-related fatigue assessment scale was formed after 2-round consultation,including 3 dimensions and 20 items,which were:8 items for the physical fatigue,5 items for mental fatigue,7 items for emotional condition.Conclusions The Chinese cancer-related fatigue assessment scale formed by Delphi technique provides a research tool to evaluate fatigue of Chinese cancer patients accurately and presents targeted nursing interventions.
5.Application of quality control circle activity in nursing document writing
Modern Clinical Nursing 2015;14(9):68-71
Objective To explore the effect of quality control circle activity on improving the quality of nursing document writing. Methods The quality control circle was established and the activity was designed to improve the quality of nursing document writing. The unqualification rate of written nursing documents was compared between pre- and post-activity. Result The unqualification rate of the written nursing documents after the activity was significantly lower than that before activity (P < 0.01). Conclusion The quality of written nursing documents can be improved by developing quality control circle activity.
6.The Empirical Research of the Impact of Health Insurance on Consumption for Urban and Rural Households
Chinese Health Economics 2013;(10):5-7
Objective: To explore the effect of health insurance on consumption for rural and urban households. Methods: Using empirical study with the method of quasi-social experiment. Results: Households with health insurance have more consumption than those without health insurance. The higher the coverage of family health insurance improves, the more effects medical insurance would encourage family consumption. Meanwhile, the marginal effect of health insurance on rural households ’ consumption is much bigger than that of urban households. Conclusion: Through enhancing households’ risk tolerance, health insurance reduces households’ precautionary saving motivation and impels to increase the current consumption.
7.Investigation and Analysis on Medical Students' Professional Attitude in Shanghai
Chinese Medical Ethics 2017;30(3):304-307
Objective:To understand the current situation of medical students' professional attitude,find out the exiting problems and put forward some corresponding suggestions.Methods:The medical students' professional attitude was investigated using questionnaire in Shanghai.FResults:Some medical students lacked of professional confidence;the students expected highly towards compensation benefit;the professional satisfaction was low.There existed a correlation between professional values,expect and satisfaction.Conclusions:Perfecting pre-service training is a necessary prerequisite to improve medical students' professional confidence;compensation benefit is one of the referred factors for medical students to choose an occupation;improving medical students' professional view is the foundation of long-term development of medical enterprise;the professional counterpart is the key to ensure medical students' professional satisfaction.
8.Application of rapid prototype and 3D printing in therapy of complex pilon fractures
Chinese Journal of Orthopaedic Trauma 2016;18(1):42-46
Objective To investigate the value of 3D rapid prototype technology in therapy of complex pilon fractures.Methods In this study,60 patients with pilon fracture who had been hospitalized during January 2013 to May 2014 were randomly and equally divided into a 3D group and a control group according to their hospitalization order.The 3D group:21 males and 9 females,an average age of 34.8 ±6.0 years,13 cases of AO type C2 and 17 ones of AO type C3.The control group:21 males and 9 females,an average age of 35.8 ±6.2 years,12 cases of AO type C2 and 18 ones of AO type C3.The 3D group received surgery aided by rapid prototype and 3D printing while the control group underwent conventional surgery with open reduction and internal fixation.In the 3D group,the distal tibia models were manufactured by 3D rapid prototyping technology based on the 3D reconstructions which were accomplished by computer aided technology.The diagnosis,classification and preoperative plan were then conducted using the models.The 2 groups were compared in terms of operation time,postoperative skin necrosis and infection,and Maryland foot function scoring at the last follow-up.The 2 groups were compatible in preoperative demographic data (P > 0.05).Results There were significant differences between the 3D and control groups in operation time (65.1 ±4.8 minutes versus 80.5 ± 3.6 minutes) and rate of postoperative complications [6.7% (2/30) versus 16.7% (5/30)] (P <0.05).There was no significant difference between the 2 groups in the excellent to good rate by Maryland foot function scoring at the last follow-up [76.7% (23/30) versus 73.3% (22/30)] (P > 0.05).Conclusion Since rapid prototype and 3D printing technology can display the morphology of pilon fracture intuitively and stereoscopically,it helps surgeons with accurate assessment of the fracture.3D printed models of the pilon fracture pre-operatively raise the accuracy of reduction,reduce both operation time and incision complications,and facilitate functional recovery.
