Advance medical directive is a statement made by a patient ,which indicates patient′s acceptable or unacceptable treatments , when he or she is not competent to make a medical decision .There are two types of ad-vance directive , which are living will and durable power of attorney for healthcare .The paper will briefly introduce advance directive′s history and analyse its controversies throughout the world .In China , most people don′t own an advance directive .When these patients are faced with medical emergency , their desires can not be known by their relatives, and not to mention let their relatives respect their desires .Cultural barrier and the lack of regulation and propaganda on advance directive are the main reasons cause the current situation of advance directive in china . Based on the analyses above , the paper offers a suggestion that it is necessary to widely promote advance directive in China .During the process of promoting advance directive , should pay attention to guide and respect traditional culture .

The aim of this study is to invistigate the effects of heparinization and the reversal of heparin activity with protamine on platelet function during extracorporeal cardiopulmonary bypass. The venous blood of 10 healthy volunteers was collected in tubes containing 3 2% trisodium citrate or 25??/ml heparin. The expression of P selectin (a secretion marker of platelets) and activated fibrinogen receptor GP Ⅱb Ⅲa (an aggregation marker of platelets) on normal platelets in response to the treatment with heparin and protamine in vitro were examined using whole blood flow cytometry. The results showed that heparin (5～50?g/ml) could increase adenosine diphosphate (ADP) induced expression of P selectin and GPⅡb Ⅲa in a dose dependent manner ( P

Objective To study the ultrastructure of ovary lymphatic stomata in human and compared with the animals′. Methods The morphology of human ovary surface was examined using scanning electron microscopy and the lymphatic stomatas were counted by the ELESCOPE computer image processing system. Results The human ovary epithelium was composed of cuboidal and flat cells. There were lymphatic stomatas not only among the cuboidal cells, but also among the cuboidal and flat cells. The stomata were usually circular in shape and about 1 80?0 82??m in diameter, 6 27?2 65??m in circle. Lymphatic stomata in external surface of ovary mucinous tumor was also found. Conclusion There are ovary lymphatic stomatas in human. These stomatas connect lymphatic vessels in ovary with the peritoneal cavity. They also present morphological basis for early\|metastasis of ovary tumor. [

Objective To establish a method for identification and quality control of Rhizoma Acori Talarinowii. Methods The medicinal herb of Rhizoma Aeori Talarinowii was identified by its origin and TLC. High-performance liquid chromatography (HPLC) was used to determine the content of β-asarone in Rhizoma Acori Talarinowii. Results The results of TLC showed that there were some spots with the same color in the position having the same relative retention time between the tested medici-hal material and the control. The results of HPLC showed that a good iinearity was in the range of 0. 1～0. 6 βg, the regression equation was Y=37158. 2X-589. 5(r=0. 999 7), and the average recovery was 96. 78 % (RSD=0. 95 %). Conclusion The method is simple and reproducible, and can be used for the quality control of Rhizoma Acori Talarinowii.

Nowadays there are still a lot of controversies about indications methods and timing for tracheotomy in the patients who need long-term mechanical ventilation.Some recent studies have shown that early tracheostomy can increase patient comfort compliance and may reduce the use of sedatives,decrease ventilator associated pneumonia occurrence,reduce duration of mechanical ventilation and ICU stay.Presently we consider that the early tracheostomy may benefit patients needing long-term mechanical ventilation,and percutaneous dilational tracheostomy is a better way of tracheotomy,however we need to correctly grasp the indications.

Objective To establish a method for identification and quality control of Rhizoma Acori Talarinowii. Methods The medicinal herb of Rhizoma Acori Talarinowii was identified by its origin and TLC. High-performance liquid chromatography(HPLC) was used to determine the content of ? -asarone in Rhizoma Acori Talarinowii. Results The results of TLC showed that there were some spots with the same color in the position having the same relative retention time between the tested medicinal material and the control. The results of HPLC showed that a good linearity was in the range of 0.1～ 0.6 ? g, the regression equation was Y=37158.2X-589.5(r=0.999 7), and the average recovery was 96.78 % (RSD = 0.95 % ). Conclusion The method is simple and reproducible, and can be used for the quality control of Rhizoma Acori Talarinowii.

Objective To investigate the evaluation of the employing hospital about nursing undergraduate students,to understand the actual working capacity of graduates and explore the quality requirement and individual needs of nuring undergraduates according to the findings,to improve the quality of nursing undergraduates and personnel training specifications.Methods The self-evaluation questionnaires on nursing undergraduates was used to investigate eight hospitals which accepted three or more graduates of our college by letter investigation.Results The employing hospital had the highest satisfaction degree on the moral character and working attitude,respectively 98.1%and 96.2%;the satisfaction degree of management and research capability was the lowest,respectively 81.0%and 80.0%. Conclusions Overall assessment of the quality of graduates is better,the graduates' clinical competence,interpersonal relations and psychological quality is satisfactory,nursing skills and adaptability should be improved;foreign language,scientific research,administration and management capacity is rehtively weak.In the future,the college should adapt to the reeds of employers in the teaching process,strengthening the training of practical ability and adaptability,using appropriate methods to enhance research and foreign language skills,appropriately adjust training goal of undergraduates.

Objective To investigate the etiological diagnosis and therapy of liver function lesion after kidney transplantation.Methods By analyzing the etiological factor of 82 cases of liver function lesion,we provided a reasonable and operative therapy scheme in kidney post-transplantation.Results Of 82 cases,the number of drug toxicity and viral hepatitis B which result in liver functional lesion were 70 cases(85 5%) and 12 cases(14 5%) respectively.The former were all cured,8 cases in the latter were cured and the other 4 cases were died from acute hepatic failure.Conclusions The liver function lesion of post-transplantation should be diagnosed carefully and treated particularly.Morever,the adjustment of immuno-suppressive drugs and monitoring circlosporin A concentration should be done for the patients with liver function damaged.
