Aim To construct prokaryotic expression vector for endogenetic angiogenesis inhibitor Arresten gene and to express recombinant.Pharmacology experiments found that the expression product had the function of restrain blood vessel growing on the chorioallantoic membrane(CAM).Methods The total RNA was extracted from the placenta organize of the normal puerpera,and Arresten gene was amplified by RT-PCR to construct recombinant vector pBV220-Arr.Then,it was transformed into E.coli JM109 for yielding recombinant human Arresten protein.The method to detect inhibiting angiogenesis activity was CAM study.Results The plasmid pBV220-Arr.could be expressed in E.coli JM109 from two hours to eight hours,and the expression yield reached the highest in two hours.The Arresten protein could restrain blood vessel growth of CAM evidently than that of angiostatin.Conclusion The recombinant plasmid pBV220-Arr was construted successfully and the target protein Arresten can express in E.coli JM109,the protein of Arresten had the evident effect of inhibite the activity of angiogenesis.

The humanistic quality education of undergraduate clinical medical students is a system of education throughout the whole process of medical education.Some aspects include new career planning education,medical humanities quality courses,social practice,professional courses,clinical practice and evaluation of humanistic quality education need to design and control,which are necessary to achieve a good education results.

Objective:Two experiments were performed to research the effects of visual field factor on pseudoneglect and to test the theories about neglect and pseudoneglect.Methods:Experiment 1 employed the landmark task and greyscales task in tachistoscopic and forced-choice conditions.Experiment 2 employed the greyscales task and tachistoscopic visual three-field technique.Results:Experiment 1 manifested that greyscales had no crossover effect;the length factor had effect on the greyscales task as the landmark task,but it only affected the bias magnitude,not the error direction.Experiment 2 indicated that the main effect of visual field was significant:when the greyscales were presented in the middle or right,pseudoneglect manifested,but when in the left,pseudoneglect vanished.Conclusion:The results provide evidence supporting the hypothesis that the perceptual distortion derives from the attentional process.

Objective To explore the influence of self-management education on quality of life of patients with deep vein thrombosis. Methods 60 cases of deep vein thrombosis patients were randomly divided into the experimental group and the control group with 30 cases in each group, two groups basically received the same medication treatment, the control group held conventional health education, The experimental group implemented self-management education.Life quality was compared before education and 3 months after education was compared between the two groups. Results Before self-management education, the scores of quality of life of the two groups showed no difference; after three months of selfmanagement education, the score of body's function, psychological function, social function and total score of quality of life were obviouly different.However, there were no significant differences in material life. Conclusions Self-management education can improve the quality of life of patients with lower extremity deep vein thrombosis.

Objective To investigate the effects of clonidine on the visceral pain induced by acute myocardial ischemia. Methods Male SD rats weighing 250-280 g were operated upon under general anesthesia with intraperitoneal methane 1.2 g/kg and local infiltration of the skin incision. After tracheal intubation, the animals were mechanically ventilated (VT = 5-7 ml/kg, RR = 75 bpm). The anterior descending branch of left coronary artery was occluded with a snare through the left 4 th intercostal space. The animals were then fastened to a brain stereotaxic instrument and a burr hole was made in the skull. A glass micro-electrode was inserted into the brain. The discharges of noxious stimulation responding neuron (NSRN) in parafascicular nucleus were recorded. Twenty-four rats detected NSRN showed response to coronary artery occlusion (CAO) were randomly divided into 4 groups (n =6 each): group Ⅰ CAO + normal saline 0.1 ml; group Ⅱ CAO + elonidine 30 μg; group Ⅲ CAO + clanidine 100 μg; group Ⅳ CAO + clonidine 100 μg + yohimbine (an α2-adrenergic receptor antagonist) 200 μg. In group Ⅳ , clonidine was administered intravenously 15 min after CAO, and then yohimbine was injected intravenously 15 min later. The discharges of NSRN were recorded every 5 min for 60 min from the beginning of CAO. Results Clonidine 100 μg significantly inhibited the increased frequency of nociceptive discharge rate of NSRN after CAO. However, this effect could be blocked by the α2-adrenergic receptor antagonist yohimbine.Conclusion Clonidine 100 μg can reduce the visceral pain induced by acute myocardial ischemia through activiting α2-adrenergic receptor.

0.05). The BHR distribution was slight 31.9%, mild 43.5%, moderate 24.6%, no severe BHR were found in this study, showing less correlation between the percentage of predicted FEV 1 and the PD 20FEV 1-His in the elderly (r=0.277, P

Objective To evaluate the influence of psychological status on the quality of life of patients with breast cancer and supply evidence for improving quality of life for these patients. Methods Patients were divided into two groups according to median score of psychological status(11.43) by life quality inventory.The designed data of the quality of life in different domain were statistically analyzed. Restilts The quality of life of patients with good psychological status was higher than that with poor psychological status (P＜0.01). Conclusions Psychological status was the most pivotal factor that influences the quality of life of patients with breast cancer.Selective psychological nursing is expected to improve their quality of life.

Objective: To explore the influence of mild extrapyramidal signs(EPS) on the ability of daily living(ADL) of aged people and the countermeasures in nursing.Methods: We recruited 131 aged people without overt neurologoical diseases,rated their EPS and ADL according to an abbreviated version of the motor portion of the Unified Parkinson's Disease Rating Scale(UPDRS) and assessed the influence of EPS on ADL by logistic regression analysis.Results: Those with EPS were significantly more advanced in years(P

Objective To research patients with ophthalmologic perioperative information systems, strengthening the information management of nursing work, achieving consensus and sharing of health care information resources, and then to explore the clinical application effects of this ophthalmologic peri- opera-tive information systems. Methods The convenient sampling method was used in the study. The control group was consisted of 1 740 patients in our hospital from January to March 2013 (before the application of ophthalmologic perioperative information systems). The observation group included 2 078 patients of the same hospital (after the application of ophthalmologic perioperative information systems). The control group adopted routine pre- operative information acquisition method, the observation group applied ophthalmologic perioperative information systems, which included input function, reading function and statistical function. The incidence rate of canceled operation and satisfaction were compared between two groups. Results Ophthalmologic peri- operative information systems provided patients with information gathering, query and analysis in different periods. The rate of the canceled operation reduced in the observation group from 3.74% (65/1 740) to 2.69% (56/2 078) in the control group, χ2=3.91, P<0.05. The satisfaction degree increased from 91.84 % (1 598/1 740) in the observation group to 96.78% (2 011/2 078) in the control group, χ2=44.60, P<0.05, the difference was statistically different. The hospitalization days from April to September in 2013 shortened compared with those of the same period in 2012. Conclusions Ophthalmologic peri- operative information systems promotes the scientific and informatization of nursing information, which is worthy of wide clinic application.
