BACKGROUND: The p27, one of the cyclin-dependent kinase inhibitors in renal disease, regulates cell growth through affecting cellular events. Abundant evidence has suggested that p27 has great role in regulating re nal cell proliferation, hypertrophy, differentiation and apoptosis, etc. OBJECTIVE: To investigate the relationship of protein 27 expressions in renal tissue with cell proliferation and apoptosis. DESIGN: Completely randomized grouping design, control animal experi ment. SETTING: Nephrology Laboratory, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology. MATERIALS: This experiment was carried out at Nephrology Laboratory of Internal Medicine, Tongji Hospital and Micro-Pathology Center in Tongji Medical College from September 2004 to January 2005. A total of 48 adult male SD rats were enrolled, all belonged to cleaning grade. METHODS: ①Establishing diabetic models: diabetic rat models were es tablished with streptozotocin, 60 mg/Kg, given through intraperitoneal in. Jection in the experimental group. Blood glucose and urine glucose from caudal vein were measured after 48 hours. Animals in experimental group whose random serum glucose at least 16.7 mmol/L and urine glucose ()- ()-() were regarded as successful models. ②Six rats in experimental group and the control group, respectively were sacrificed in the experimental pe riod of the 3rd, 7th, 14th and 28th days. Before sacrificed, creatinine clearance (Ccr) was measured. Concentration of Retinal binding protein (Rbp) in urine was measured. Proteinuric elements were analyzed by sodium dodecyl sulfate-polyacrlamide gelelectrophoresis (SDS-PAGE). ③Renal tissues were observed pathologic changes through light microscopy and electronic mi croscopy. ④Expression of p27 and proliferation cellnuclear antigen (PC NA) were detected by immunohistochemical staining method, and apoptosis was determined by Terminal deoxynucleotidy 1 transferase-mediated dUTP nick end labeling (TUNEL). We use positive glomerular cells / total glomerular cells to present positive rate and apoptosis rate. ⑤The data were analyzed for statistically significant group difference using unpaired t test and Spearman correlative-analysis. MAIN OUTCOME MEASURES: Renal function, urine protein, p27 ex pression in glomerular cells, positive rate and apoptosis rate of proliferating cell nuclear antigen (PCNA) expression and compared with the control group. RESULTS: Totally 48 rats were involved in the result analysis. ①Changes of pathology: At the 7th day after establishing models, glomerular hypertro phy was found through light microscopy and focal fusion of epithelial foot processes through electron microscopy. At the 14th day, mesangial region, which kept expanding through electronic microscopy, was seen under electron microscope. At the 28th day, slight segmental hypercellularity be gan to show in light microscopy. ②Ccr and Rbp levels of diabetic rats were higher significantly than those in the control group at the 7th, 14th and 28th days (t=2.143-3.004,P ＜ 0.05 ). The results of SDS-PAGE showed that middle and low molecular protein could be observed in every group from the 3rd day. ③The level of p27 expression in glomerular cells were lower obviously at the 3rd day(t=2.536,P ＜ 0.05), but higher at the 7th, 14th and 28th days in diabetic rats, which was higher remarkably than that in the control group (t=2.704-2.823,P ＜ 0.05). The number of PCNA positive cell in diabetic glomerulus became the largest at the 3rd day, then decreased continuously, it was still higher than that in the control group at the 7th dan 14th days (t=2.681,2.525,P ＜ 0.05), but became normal at day 28. The number of TUNEL positive cells in glomerulus also increased significantly at the 3rd day (t=2.764,P ＜ 0.05), but it was smaller than that in the control group at the 7th, 14th and 28th days(t=2.096-2.627,P ＜ 0.05). ④The level of p27 expression and the number of PCNA positive cells in glomerulus were negative correlated (r=-0.446, P ＜ 0.05). The level of p27 expression and the number of TUNEL positive cells in glomerulus were also negative correlated (r=-0.517, P ＜ 0.05).CONCLUSION: Functional impairment of reabsorption induced by proximal convoluted renal tubule and high filtering of glomerulus in early diabetics occurs synchronously. Protein p27 may be participated in the occurring and developing of diabetic nephropathy by checking of proliferation and apoptosis of renal cell in the early stage of diabetes.

Methoxyadiantifoline 10 mg/kg i.v. significantly increased the arrhythmia- inducing dose of aconitine in anaesthetized rats, and that of ouabain in anaesthetized guinea pigs. It markedly prevented ventr icular fibrillation induced by chloroform. Methoxyadiantifoline is also effective in preventing reperfusion-induced arrhythmias in anaesthetized rats. It was demonstrated that methoxyadiantifoline slowed heart rate significantly, and prolonged P-R and Q-Tc interval of ECG in rats.

The natural process of life and death has been profoundly and widely involved and increasingly manipulated by the fast developed technology of life science,which could change the human beings' state of life as well as the state of death.Thus,human beings are motivated to think multidimensionally on life and death from the perspective of science,such as the weakening of sacredness of life,the technology employed in life,the socialization of lifestyles,the exploration of the nature of death,the pluralism of different ways of death and the systematization in the education of death.These considerations will no doubt contribute to the mutual promotion of the development of morality and the advancement of life science technology.

The lack of organs has been an crucial limiting factor for Chinese organ transplantation,thus it is in urgent need to effectively increase the number of donor organs.This article holds that,besides through publicity and education to promote unpaid voluntary organ donation,some incentive mechanisms are also required to serve as useful complements.Therefore,organs' origin can be expanded to a certain extent,and the intense supply and demand in organ transplantation can also be eased.Unifying organ transplantation practice in China,this paper explains the necessity of organ donation incentive mechanisms from both theoretical and practical significances,reveals the main elements of the incentive mechanisms,and explores the realization means.

Methoxyadiantifoline ( MAF) is a new alkloid isolated from Thalictrum Omeience W.T.Wang.During 3 min reperfusion after 10 min of coronary ligation, MAF 5 ?mol/L significantly decreased the incidence of isolated rat hearts with ventricular arrhythmias ( VF and VT ) . It delayed the onset of ventricular fibrillation and shortened its duration and markedly prolonged the time of normal sinus rhythm. It also significantly decreased the release of LDH from the myocardium in isolated rat hearts. In addition , MAF 5 ?mol/L could decrease the heart rate and coronary resistance. The results suggest that MAF possessed protective effects on the reperfusion injury in isolated rat hearts.

AIM: To study the possibility that yellow wine improves the pathological changes of atherosclerosis in vivo. METHODS: Six weeks old LDL receptor knockout mice (n=48) on a high-fat and L-methionine diet developed plasma hyperhomocysteinemia and atherosclerosis. The animals were randomly divided into yellow wine group, red wine group, ethanol group and control group (n=12 in each group) and were sacrificed after 14 weeks. The levels of plasma lipids and homocysteine in serum were examined. The morphological changes of aorta artery and the atherosclerosis of aorta sinus were observed under microscope. The expression and activation of matrix metalloproteinase-2 (MMP-2) were determined by the method of immunohistochemistry. RESULTS: No significant difference of plasma total cholesterol, triglyceride or high density lipoprotein cholesterol among groups was observed. Plasma homocysteine was significantly decreased in yellow wine group as compared to other three groups (P<0.01). Compared to ethanol and control groups, use of yellow wine and red wine significantly reduced the atherosclerosis lesion area (P<0.01). However, no significant discrepancy between the yellow wine group and red wine group was found. Compared to control group, the expression of MMP-2 in yellow wine group, red wine group and ethanol group decreased by 26.3%, 27.6% (P<0.01) and 5.7% (P>0.05), respectively. The activity of MMP-2 in yellow wine group, red wine group and ethanol group decreased by 31.7%, 32.5% (P<0.01) and 6.7% (P>0.05), respectively. CONCLUSION: Yellow wine and red wine inhibit the expression of MMP-2 and improve the pathologic changes of atherosclerosis, indicating that they have benefic effects on cardiovascular system.

Twenty five new beta-aminoalcohols containing nabumetone moiety were prepared via the reduction of potassium borohydride with a convenient and efficient procedure, starting from beta-aminoketones that have been synthesized by our group. Their chemical structures were determined by IR, MS, 1H NMR, 13C NMR, HR-MS and antidiabetic activities were screened in vitro. Preliminary results revealed that the antidiabetic activity of most beta-aminoalcohols were better than that of the corresponding beta-aminoketones. Although most compounds showed weak antidiabetic activity, the alpha-glucosidase inhibitory activity of compounds 5hd(1) and 5id(2) reached 74.37% and 90.15%, respectively, which were superior to the positive control. The relative peroxisome proliferator-activated receptor response element (PPRE) activity of five compounds were more than 60%, among them compound 5ca possessed the highest activity (112.59%). As lead molecules of antidiabetic agents, compounds 5hd(1), 5id(2) and 5ca deserve further study.
