The basic research and development of xeno-transplantation technique has been a new field. The article analyzed its current situation and problems, discussed the ethical problems the researchers and physicians faced, and raised a series of ethical principles which should be obeyed in xeno-transplantation, that is: stick to combining humanism and utilitarianism; observe the technological and sanitary criterion, choose the graft cautiously; Be attentive and loyal to the recipient's health; no harm and beneficial to the humankind. Besides, the article explored the importance of setting up laws and regulations about xeno-transplantation.

A large number of studies showed that hairy leukoplakia,pseudomembranous candidiasis,Kaposi' sarcoma,non-Hodgkin's lymphoma,linear gingival erythema,necrotizing ulcerative periodontitis and necrotizing ulcerative gingivitis were the most common lesions in patients with HIV infection and AIDS,and their higher prevalence and incidence rates correlated with the falling CD4 counts and higher virus load of the patients.The use of highly active antiretroviral therapy(HAART) was associated with decreases in the prevalence of oral diseases.Oral manifestations may represent early signs of AIDS di-sease and call attention to disease progression.Oral fluid has been shown to possess superior sensitivity for HIV antibody detection as serum.Abstract:SUMM ARY A large number of stud ies showed that hairy leukoplakia,pseudomembranous cand id iasis,decreases in the prevalence of oral d iseases.Oral manifestations may represent early signs of AIDS d i-sease and call attention to d isease progression.Oral fluid has been shown to possess superior sensitivity forHIV antibody detection as serum.Kaposi’sarcoma,non-Hodgkin’s lymphoma,linear gingival erythema,necrotizing ulcerative periodonti-tis and necrotizing ulcerative gingivitis were the most common lesions in patients with HIV infection and AIDS,and their higher prevalence and incidence rates correlated with the falling CD4 counts and higher virus load of the patients.The use of highly active antiretroviral therapy(HAART) was associated with

Objective To investigate the effects of Astragalus membranaceus and Angelica sinensis on the hemodynamics and pathological features of arterial wall in restenosis of blood vessel in rats in order to find the potential mechanism of the effect of Astragalus membranaceus and Angelica sinensis in preventing restenosis after ablation of intima. Method Thirty SD rats were randomly divided into 5 groups (6 each):control group (C),model group (M),Astragalus membranaceus treatment group (H),Angelica sinensis treatment group (D),and combined Astragalus membranaceus with Angelica sinensis treatment group (HD). The restenosis model was reproduced by denuding rat's aorta endothelium with balloon catheter in all the groups except group C. After intramuscular injection of Astragalus membranaceus 0.42ml/(kg?d) in group H,Angelica sinensis 0.21ml/(kg?d) in group D,and Astragalus membranaceus 0.42ml/(kg?d) together with Angelica sinensis 0.21ml/(kg?d) in group HD for 21 days,the changes in hemodynamics and the pathological features of arterial wall were observed in all the groups. Result Compared with rats of group C,in which the intima was smooth and the smooth muscle cells (VSMCs) in media were orderly arranged,the intimal thickness of aorta,pulsatile index (PI) and resistance index (RI) increased,while the diameter of lumen,blood velocity decreased remarkably in group M. Compared with the rats in group M,the extent of hyperplasia and thickness was notably reduced,RI and PI were lower while blood velocity was lowered in group H,D and HD after being treated for 21 days. Conclusion Hyperplasia induced by remaval of endothelial cells may be reduced and blood circulation may be improved to different extents by individually or simultaneously use of Astragalus membranaceus and Angelica sinensis,thus preventing restenosis of the aorta after removal of its intima.

The compounds were isolated from Aoonitum coreanum (Lev1.) Rapaics and identificd by TLC, IR, MS and NMR, as ?-sitosterol (Ⅰ), daucosterol (Ⅱ), Guan-Fu base A (Ⅲ),GuanFu bas. G (Ⅳ), condelphine (Ⅴ), Guan-Fu base Ⅰ (Ⅵ), hetisinone (Ⅶ), isoatisinum chloride (Ⅷ), atisinum chloride (Ⅸ), and Guan-Fu base z (Ⅹ) from the root. Compounds Ⅲ and Ⅸ were also found in the aerial parts of the plant. compounds Ⅱ, Ⅴ, Ⅶ and Ⅷ were obtained for the first time from this plant. Most of them exhibited antiarrhythmic activlty.

Objective To observe changes on those parameters on pletelet and hemoglobin of urinaemia patients by treatments of dialysis.Methods candidators are divided into three groups respectively-a control group,two case groups.The two case groups are consist of patients who are treated through dialysis on not.In the three groups,the parameters on pletelet,hemoglobin,MPV and PDW are measured on hemocytometer in our laboratory. Results Dramatic difference is made in the parameters on PLT,Hb,MPV and PDW between the formers of dialysis and the control group.(P

To evaluate percutaneous dilatational tracheostomy (PDT) with continuous aspiration of subglottic secretions in intensive care unit (ICU) elder patients.A total of 32 elder patients were selected randomly for PDT and 36 controls for traditional surgical tracheostomy (TST).The PDT group required regular mechanical ventilation with continuous aspiration of subglottic secretions.The operative duration was significantly shorter in PDT group than that in TST group [ ( 10.6 ±3.4)vs.(30.9 ±7.1)min,P ＜0.01].Incision length was significantly less in PDT group than that in TST group [ ( 1.3 ± 0.2 ) vs.(3.2 ± 0.3 )cm,P ＜0.01].Blood loss volume was significantly less in PDT group than that in TST group [ ( 10.4 ±3.8 ) vs.(40.7 ± 11.7 ) ml,P ＜ 0.01].The incidence of ventilator associated pneumonia (VAP) was significantly lower in PDT group than that in TST group ( 15.6％ vs.38.9％,P ＜ 0.05 ).With multiple advantages of mini-invasiveness,safety,simplicity,convenience and easier installation,PDT is quite suitable for elder patients in ICU.

Because of insufficient intake,synthesis disorder,metabolic disorder and excessive consumption,patients with cirrhosis often lead to malnutrition. Providing scientific nutritional support and guiding the patients to a reasonable diet can effectively improve the liver metabolism and reduce the complication of cirrhosis such as hepatic encephalopathy,and improve the quality of life and survival rate. This article described the nutritional metabolism disorder in patients with cirrhosis and nutritional treatment in hepatic encephalopathy.

Objective To investigate the effect of nasal continuous positive airway pressure (NCPAP) on cardiac function in children with pneumonia complicated with heart failure.Methods Twenty-two children with pneumonia complicated with heart failure were selected in emergency room of Beijing Children′s Hospital Affiliated to Capital Medical University from Oct.2008 to Mar.2009,aged 1 month and 15 days to 2 years and 8 months,prospective clinical study.Cardiac function[including cardiac index(CI),heart rate(HR) and stroke volume index(SVI)] before and after NCPAP 0.04-0.05 kPa for 30 minutes were monitored by ultrasonic cardiac output monitoring(USCOM).Results After the application of 0.04-0.05 kPa NCPAP for 30 minutes,the heart rate decreased signi-ficantly [(173?10) beats/min vs (151?13) beats/min P0.05].Conclusions NCPAP might improve cardiac function by increasing stroke volume index and decreasing heart rate and respiratory rate in children with pneumonia complicated with heart failure.

Objective To investigate the status of personality, family function and psychological resilience towards employed nurses, and to explore the relationship among personality, family function and psychological resilience. Methods Four instruments were applied to investigate 240 employed nurses from comprehensive Grade 3A hospital of Fujian Province, which were the Characteristics Questionnaire, Family Intimacy Scale (FACEⅡ-CV), Self-resilience Scale and Personality Traits Questionnaire. Results The correlation analysis showed that nurses′ personality traits, family functions and psychological resilience were closely related. The multiple regression and analysis showed that 40%of the variance for employed nurses′psychological resilience could be explained through considering personality dimensions, family cohesion and adaptability. Conclusions Personality, family functions and psychological resilience towards employed nurses are closely related as both internal and external protective factors.
