The papers on information ecology theory in foreign and domestic libraries were analyzed and its appli-cation value in book acquisition was studied.The information ecosphere formed by readers, acquisition members and experts was put forward and how to make the information ecosystem reach its new balance by dynamic regula-tion of its main components through information flow.

Objective: To study the effects and significances of lipopolysaccharide preconditioning on the activities of NF-?B and the expression of ICAM-1/LFA-1 in rats graft liver ischemia/reperfusion injury. Methods: Male Sprague-Dawley rats were divided into three groups: sham operation group(Sham group),orthotopic liver transplantation group (OLT group) and LPS preconditioning group (LPS group). Only dissecting hepatoduodenal ligament was perfomed in Sham group. Experiments of OLT were performed by two-cuff method in OLT group and LPS group. The activities of NF-?B and the expression of ICAM-1/LFA-1 in hepatic tissue ,the levels of ALT,AST in inferior caval vein blood were detected at 0,60,180 min after dissecting of hepatoduodenal ligament in Sham group and after portal vein reperfusion in OLT group and LPS group. Results: Compared with those in Sham group at the different time points respectively,the activities of NF-?B and the expression of ICAM-1/LFA-1 were higher in OLT group and LPS group(P0.05) at 0 min after reperfusion,they were evidently higher in OLT group than in LPS group (P

Objective:To culture mesenchymal progenitor cells(MPC)from compact bone fragments in C57 mice in vitro and to study the feasibility of inducing directed differentiation of MPC into neuron-like cells in vitro. Methods:Bones of hind limbs of C57 mice were sheared into bone fragments and digested by collagenase type Ⅱ. Then,MPC were cultured in vitro and analyzed by flow cytometry for identification of its immunology phenotype. MPC of P3 in good growth were induced directionally by the supernatant cultured with primary neuron,and then detected the expression of neuronal specific markers neuron specific enolase(NSE)and neurofilament protein(NF)by immunocytochemical staining. Results:The primary MPC were cultured successfully and they grewwell after passage. Compared with that of the control group,the positive rate of CD29 and CD44 of MPC of antibody group had significant difference (P

Objective To study the possibility and effect of application of clinical pathways (CP) in patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus. Methods 280 patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus were selected and divided into the experimental group and the control group randomly. Each group had 140 cases. Clinical pathways was applied to the experimental group, while traditional nursing method was given to the control group. Treatment and nursing effect were compared between the two groups. Results The cost for hospitalization was lower, hospitalization time was shorter, the first time for functional exercise after operation was advanced and satisfaction degree of patients was increased in the experimental group compared with those of the control group. Conclusions Application of clinical pathway in patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus played a positive and effective role.

Sanger sequencing technology is the most commonly used method for genetic analysis in inherited eye disease in the past few decades on account of its long DNA sequencing read length and high accuracy.However,application of this method is limited in genetically heterogeneous diseases because of the high economic and time cost.Next generation sequencing (NGS) technology is a high-throughput,cost-effective,and highly automated method which has been widely used since 2005.Although NGS is especially suitable for studies on genetically heterogeneous inherited eye disease,overdependence on the technique itself and neglect of the assessment of the phenotype may lead to misjudgment of the testing results and higher economic burden for the patients.So far,the most common method on researches of monogenic inherited eye disease is to combine NGS and Sanger sequencing technique.Precise evaluation of the clinical phenotype of patients is very important,as it is related with selection of detection methods and determination of disease-causing mutations.

Objective To explore the teaching effect of cooperative learning approach in the training class of basic nursing operation techniques for male students. Methods A total of 82 male nursing students who were admitted into college in 2013 with a 3-year study program were divided into two groups based on mechanical sampling method, 42 students in the experimental group were trained with cooperative learning approach, while 40 students in the control group were trained with traditional teaching method. At the end of the semester, surveys were conducted and the results of students′operative skill were analyzed. Results The result of operative skills evaluation in the experiment group was 88.0 ± 6.9while that in the control group was 79.0 ± 9.2. The comparative difference between the two groups had statistical significance(t = 4.392,P<0.01). The qualified rate in the experiment group was 95.23%(40/42)while that in the control group was 70.00%(28/40).The comparative difference between the two groups had statistical significance(χ2=9.118,P<0.01). Conclusions Cooperative learning approach can improve the teaching effect of nursing operative skills for male nursing students. Thus it is an effective teaching method that deserves promotion and application in the practice teaching of Basic Nursing Techniques.

Objective To investigate effects of sevoflurane and propofol on hemodynamic changes in patients undergoing cardiac double valve replacement.Methods Totally 80 patients admitted with rheumatic heart disease were divided into sevoflurane group and propofol groups.The anesthetic drugs on hemodynamics,myocardial function and renal function were compared.Results There were statistically significant in CIL concentration,stroke volume index (SVI)and left ventricular -stroke work index (LVSWI)levels between the two groups at the same time points (F =2.467,2.4783,2.553,P =0.032,0.032,0.021).The levels of MAP,HR,PAWP,CIL,SVI and LVSWITBIL between the two groups were statistically significant at different time points (F =2.597,2.468,2.523,2.589,2.532, 2.556,P =0.032,0.021,0.030,0.021,0.024,0.023),and difference at the same group at different time points (F =2.597,2.468,2.523,2.497,2.479,2.538,P =0.032,0.021,0.030,0.034,0.034,0.038).No obvious liver and renal function damage was found during the surgery in the two groups.Conclusion Anesthesia induction of sevoflurane and propofol for patients undergoing cardiac double valve replacement has similar effects on the hemody-namics and cardiac function,without obvious damage to liver and renal function.

Objective:To investigate the effects of endoscopic local treatment for colorectal intramucosal carcinoma.Methods:42 patients with colorectal intramucosal carcinoma were treated with endoscopic local through one or few methods such as biopsy forceps resection,looping ligature and high frequency electric coagulation etc.in past five years.Results:(1)18 cases received biopsy forceps resection,3 cases received looping ligature,16cases received high frequency electric coagulatio resection,5 cases received many kinds of methods.(2)3 cases of 5 cases with advanced carcinoma were operated enlarge radical surgery except 1 cases who refused operation and 1 cases who losted operation opportunity.In the rest 37 cases,7cases were operated surgery,malignant remnants were no founded in theses colon specimens.(3)The following-up 33cases(30 cases without surgery)failed to show recurrent cancer for 1 month to 5 years.(4)In the following-up cases,the incidence of neogenesis adenoma was 57.1% in cancer with pilosity adenoma and was 15.8% in early cancer without adenoma during 1 year to 3 years after operation.Conclusions:It can achieve to healing,security and minimum invasive treatment for endoscopic local resection to colorectal intramucosal carcinoma as long as it is suitable to select case.
