Objective To exPlore the theraPeutic effect of cycloVirobuxine_D ( CVB_D) on heart failure by obserVing the influences of CVB_D on cardiac function,myocardial morPhology and structure in rats with heart failure. Methods The rat model of heart failure was established by ligating left anterior descending coronary artery,and then the rats were randomly diVided into 5 grouPs,Plus the sham grouP. EchocardiograPhy was used to assess cardiac function,including EF,LVSF,SV,HR,CO and so on. Myocardial tissue section was obtained. Change in the myocardial tissue was obserVed by HE staining. Myocardial ultra_structure was obserVed by using transmission electron microscoPe. Results As comPared with the model grouP,EF and LVSF were significantly increased in medium and high dose CVB_D grouPs (P<0. 05 or P<0. 01),SV was increased in low and medium dose CVB_D grouPs (P<0. 05),CO was increased in low,medium and high dose CVB_D grouPs (P<0. 05),LVIDs was decreased and LVPWs was increased in high dose CVB_D grouP (P<0. 05). Under light microscoPe,changes of myocardial structures were obserVed in different CVB_D dose grouPs: myocardial fiber gradually became tidy, striPes became clear, and contour became clear. The changes of myocardial ultra_structure were obserVed under transmission electron microscoPe: the myocardial fiber breakage was reduced and the number of mitochondria was increased,swelling degeneration was alleViated. Conclusion CVB_D significantly imProVed cardiac contraction and blood PumPing function of rats with heart failure, exerted mitigatiVe effect on damage of cardiac muscle fiber and mitochondria. It suggests that CVB_D may be effectiVe in the treatment of heart failure.

Objective To determine the median effective dose (ED50) of 0.375 ％ ropivacaine for ultrasound-guided subgluteus approach to the sciatic nerve block in the elderly patients.Methods Thirty ASA Ⅰ-Ⅲ patients of both sexes,aged 65-85 yr,scheduled for foot or ankle surgery under the sciatic nerve block,were enrolled in this study.The patients were placed in the Sim's position and received the sciatic nerve block using the posterior subgluteus approach guided by ultrasound.The initial dose of 0.375％ ropivacaine was 14.5 ml in the first patient and the ratio between the 2 successive doses was 1.2.The ED50 and 95 ％ confidence interval of ropivacaine were calculated by up-and-down technique.Results The ED50 and 95％ confidence interval of 0.375％ ropivacaine resulting in complete block of the sciatic nerve by using the ultrasound-guided subgluteus approach were 13.4 and 11.5-16.2 ml,respectively.Conclusion The ED50 of 0.375 ％ ropivacaine for ultrasound-guided subgluteus approach to the sciatic nerve block is 13.4 ml in the elderly patients.

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.

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.

This paper reviewed and analyzed the 72 fulfilled projects in the discipline of Otorhinolar-yngology supported in division Ⅱ of basic research of clinical medicine by the National Natural Science Foun-dation of China (NSFC) from year 2002 to 2006, and gave a brief introduction to the part of research a-chievements. The science foundation promotes Otorhinolaryngology to a quick development, and produces some outstanding research achievements with international recognition. Thus, it plays an important role in el-evating the level of discipline and bringing up specialists. According to the retrospection and analysis of the fulfilled projects and their research achievements, we hope it can objective and overall reflect research pro-gress in the field of Otorhinolaryngology, and offer as a reference to the relevant researchers and scientific re-search managers.

Objective To explore the curative effect and relative nursing care key points of Nd∶YAG laser assisting the drug treatment for patients with recurrent oral ulcer.Methods Toally 82 patients with recurrent oral ulcer treated in our department were selected and alternately divided into experiment group (41 cases) and control group (41 cases) according to the initial visiting sequence with same gender.The control group used the conventional drug treatment.On the basis of conventional drug treatment,the experiment group additionally used the Nd∶YAG laser radiation therapy.The curative effects of both groups were evaluated after relative treatment for 4 days.Results The total effective rates of curative effects of two groups had significantly statistical differences (P＜0.001).The total effective rate of the experiment group was,significantly higher than that of the control group.Conclusions Nd∶YAG laser assisting the drug treatment for the patients with recurrent oral ulcer can significantly increase the total effective rate.The correct nursing services throughout the operative process are the important guarantee of good curative effect.
