The scientific research fund is an important resource for carrying out the scientific re-search projects effectively. Whether it can be reasonable used not only relates to the fulfilled quality, bene-fit, using direction and quantity, but also makes the reformation of management methods inevitable with the increase of quantities of the projects and funds. By summarizing the previously practical experiences, this paper explored the network managements of scientific research funds based on workflow in the hospital. By means of computer and network, the concept of workflow was further introduced to the application of platform of scientific research funds management. It embodies the charactor of approval flow in workflow management system. Finally the data of scientific research funds can be shared and integrated into multi-departments, so it is beneficial to improve the fund's benefit and strengthens the supervision in the whole process manage-ment.

ObjectiveTo investigate the effect of dexmedetomidine on the median effectivetarget effectsite concentration (EC50) of remifentanil required for preventing body movement in response to skin incision made under propofol sedation.MethodsForty ASA Ⅰ or Ⅱ patients aged 20-50 yr weighing 45-58 kg scheduled for elective breast tumor excision were randomly allocated into 2 groups ( n =20 each):group remifentanil (group R) and group remifentanil + demedetomidine ( group RD).Sedation was induced with propofol TCI at target plasma concentration of 3.0 mg/L in both groups.In group RD dexmedetomidine 1.0 μg/kg was infused iv over 10 min before start of propofol TCI,while in group R equal volume of normal saline was infused instead of dexmedetomidine.Remifentanil TCI was started with target effect-site concentration set at 3.0 and 2.5 μg/L in groups R and RD respective at 13 min after beginning of propofol TCI.Skin incision (3 cm in length) was made when the target concentrations of propofol and remifentanil TCI were reached.Body movement was assessed by a nurse not involved in this study.EC50 and 95% confidence interval (CI) of remifentanil were determined by up-and-down technique.The target effect-site concentration was increased or decreased by 20% depending on the response of the previous patient to skin-incision.ResultsThe EC50 of remifentanil for preventing body movement in response to skin incision performed under propofol sedation was 1.7 μg/L (95% CI 1.5-1.9 μg/L) and 2.5 μg/L (95% CI 2.2-2.7μg/L) in groups RD and R respectively.The EC50 of remifentanil was significantly lower in group RD than in group R.ConclusionDexmedetomidine 1.0 μg/kg can decrease EC50 of remifentanil for preventing body movement in response to skin incision made under propofol sedation.

Objective To investigate the effect of dexmedetomidine on bispectral index (BIS) value at loss of consciousness (LOC) caused by propofol given by target-controlled infusion (TCI).Methods One hundred and twenty ASA Ⅰ or Ⅱ patients,aged 20-50 yr,weighing 41-68 kg,scheduled for general surgery were randomly divided into 3 groups (n =40 each):propofol group (group P),dexmedetomidine 0.5 μg/kg + propofol group (group D1P) and dexmedetomidine 1.0 μg/kg + propofol group (group D2P).The patients in each group were randomly assigned into 5 subgroups ( n =8 each):groups P0-4 receiving TCI of propofol with the target effect-site concentration (Ce) set at0,1,2,3 and 4 mg/L respectively.Groups D1P0-4 received iv infusion of dexmedetomidine 0.5 μg/kg at a rate of0.05μg·kg-1 ·min-1 and TCI of propofol with the target Ce set at 0,1,2,3 and 4 mg/L respectively at 5 min after the end of dexmedetomidine infusion.Groups D2 P0-4 received iv infusion of dexmedetomidine 1.0 μg/kg at a rate of 0.1μg· kg- 1· min- 1 and TCI of propofol with the target Ce set at 0,1,2,3 and 4 mg/L respectively at 5 min after the end of dexmedetomidine infusion.Three minutes after TCI of propofol was started,OAA/S score and BIS value were recorded.The OAMS score ≤ 2 was defined as LOC.The EC50 and 95% confidence interval of propofol for LOC and BIS50 and 95% confidence interval at LOC were calculated by Probit analysis.Prediction probability (Pk) of BIS value at LOC was calculated using Smith method.Results Compared with group P,EC50 was significantly decreased,BIS50 was significantly increased ( P < 0.05 or 0.01 ),and no significant change was found in Pk in groups D2 P and D1 P ( P > 0.05).There were no significant differences in EC50,BIS50 and Pk between groups D2 P and D1P ( P > 0.05).Conclusion BIS value can accurately predict the level of consciousness during anesthesia with dexmedetomidine and TCI of propofol,but BIS value is increased at LOC.

Objective To set up an effective and low-price way for enriching dendritic cells precursor from chronic myelogeous leukemia by Percoll density gradients.Methods Peripheral blood mononuclear cells(PBMCs) were collected by separation through Ficoll-Hypaque,then PBMCs were separated by 55% Percoll gradients. The cell type and DCs expressing CD1a,CD86 were detected in the high-density group(C),low-density group(B) and non-Percoll separation group(A).Results After separation of 55% Percoll,the percentage of promyelocytes and myelocytes in group B was obviously higher than those in group A and group C(P

Objective To identify major factors which affect the completion quality of projects and build predictive models,and to propose strategies and suggestions for total process quality management of clinical research projects of the hospital.Methods Collect relevant literatures from home and abroad;consult completion reports of various research projects completed from 2003 to 2010 and sum up problems found in such projects.Carry out in-depth interviews with principal investigators,supervisors of scientific research of the hospital as well as administrators of sponsor institutions.A questionnaire survey was made on completed clinical research projects undertaken from 2003 to 2010.Results Six key factors affecting implementation of such projects were derived from factor analysis,which are research technology and external environment,project teamwork,research subject availability,project organization,manpower input,and research design.A multiple logistic regression analysis found project internal management and manpower input as two leading predictive factors for project completion outcomes,while the former has a greater impact than the latter.Conclusion Project management should focus on the 6 key factors affecting project quality.The two main predictive factors should attract greater attention and resources in both supervision and management.

Objective To know the situation of HCH and DDT residues in the health foods in Shandong Province, China. Methods HCH and DDT residues in 102 different kinds of health food samples were determined by capillary gas chromatography in 2006. Results The detection rate of HCH was 100%, the eligible rate was 97%, as for DDT, they were 62.7% and 96.1% respectively. Conclusion The situation of organochlorine pesticide residues in the health foods in Shandong Province is not satisfactory and to ensure the quality of the health foods, a powerful supervision should be taken, the raw materials of the health foods should be natural and no pollution.

Hypoxia/ischemia is a common clinical pathophysiological process and cause of death,and it is a common problem in extreme conditions such as high altitude,astronautics and diving.Hamartin is a kind of effective endogenous neuroprotectant and could increase cell tolerance to acute hypoxia or ischemia, thus,is of significance to research.The role of hamartin in hypoxia/ischemia has been a research focus of many scientists.Elucidating the related protective effect and its DNA methylation on hypoxia/ischemia can not only reduce injury,but also lay a basic for further studying the role of hamartin and its DNA methylation in other pathophysiological processes and provide theoretical guidance for the following clinical study.In this paper,we review the structure,mechanism and role of hamartin and the effect of its DNA methylation on hypoxia/ischemia.

Objective To analyze the balance function of injured lower lim b by dynam ic posturography. Methods Using the dynam ic posturography instrum ent, the postural evoked responses of sixty-two norm al people and two hundred and fifty-eight people with injured lower lim b bones and joints were detected. The test was included sensory organization test(SO T) and adaption test(ADT).The results of two groups were com pared by t test. Results Com pared with the norm al people, the im paired people had significant statistical differences in balance scores of SO T3-SO T6 and proportion score of dynam ic proprioception (P<0.05). There was no obvious decrease in ADT. Conclusion The balance function of injured lower lim b significantly decreases.
