Objective To explore the changes of myocardial enzymes,hepatic function,renal function and 8-iso-prostaglandin F2?(8-iso-PGF2?)in newborn infants with hyperbilirubinemia and their relationships.Methods One hundred and twenty-six neonates who were 2 to 7 days old were selected.Seventy-six cases were hyperbilirubinemia,and according total bilirubin(TB),they were divided into hyper bi-lirubinemia A group(HBE-A)(51 cases,TB 205-341 ?mol/L)and hyperbilirubinemia B group(HBE-B)(25 cases,TB≥342 ?mol/L).Fifty newborn infants with physiologic jaundice were control group(TB

Aim To study the protective effect of modified acidic fibroblast growth factor (MaFGF) on renal ischemia/reperfusion injury of rats. Methods 32 Wistar rats were divided randomly into four groups;false operative control group, model control group, 8 ?g?kg-1 of MaFGF and 16 ?g?kg-1 of MaFGF groups with 8 animals in each group. Renal pathological changes were observed by light and electron microscope. Results As shown in pathology, compared with model control group, MaFGF group could significantly reduce edema, number of leukocytes appearing in the interstitium ,distention and destroy of renal tissues. Under EM, the ultrostructure(including microvilli, mitochondria and lysosomes etc.) of the tubular epithelial cells of MaFGF groups appeared lighter in injuries or even near normal. Conclusion MaFGF has a role in attenuation of renal damage or failure after ischemia-reperfusion injury of the kidney.

Aim To explore effects of acidic fibroblast growth factor(aFGF)on the growth of renal tubular epithelial cells cultured in vitro. Methods Renal tubular epithelial cells in rats were gained through digestion by pamcreatin. aFGF was added into cultures of renal tubular epithelial cells, as experimental groups. The number of cells was counted and the shape of cells was observed at 12,24,48 and 72 h. Results Renal tubular epithelial cells were successfully obtained from kidneys. After treated for 72 h,the renal tubular epithelial cells showed different proliferation in experimental and control groups. There was no obvious difference at 12 h, but there was statistical difference between the two groups at 24 h,48h and 72 h(P

Bioethics, one of the focus subjects in 21 century,attracts the attention in the worldwide.Originated from western developed countries,it has been branded with distinct western civilization,which is disadvantageous to the development of the subject.Some suggestions are put forward as following: 1.Communication between the East and the West should be promoted in order to form a solid multi-cultural base for bioethics. For instance, in America ethics bears the imprint of religious conventionality,while in China politics is infiltrated into traditional ethical ideas. Both of them are not perfect. So they cannot form the base of bioethics. 2.Research on the "base line" of the bioethics should be emphasized in order to provide freer academic atmosphere. Transplanting the western bioethical ideas to the developing countries will never work. As for the bioethical"base line",different countries should establish feasible ethical codes according to their own actual situations. 3.Scientists should be encouraged to adopt various technical ways to explore the problems in the field of bioethics.Such methods as tissue-engineering,antologous stem-cell replanting and cell diffrenttation inducing may bring about earlier breakthrough than fetus stem-cell.Equal attention,encouragement and support should be given to bioethics.

AIM To establish the fluorescent measurement technique for H+ /K+ exchange in primary cultured IMCD cell monolayers of rabbit kidney. METHODS To measure H+ /K+ exchange in the primary cultured IMCD cell monolayers under different CO2 concentrations by the BCECF/AM fluorescent probe. RESULTS [pH], recovery rate after acid loaded in the respiratory acidosis group was 0.0620 ? 0.012, and was significantly higher than that of the control group (0.0504 ? 0.009, P 0.05). CONCLUSION The fluorescent measurements of H+ /K+ exchange in primary cultured IMCD cell monolayers of rabbit kidney has many benefits which are convenient manipulation, stable and credit result, economy and safety, this method should further be popularized.

AIM　To establish the fluorescent measurement technique for H+/K+ exchange in primary cultured IMCD cell monolayers of rabbit kidney. METHODS　To measure H+/K+ exchange in the primary cultured IMCD cell monolayers under different CO2 concentrations by the BCECF/AM fluorescent probe.RESULTS　［pH］i recovery rate after acid loaded in the respiratory acidosis group was 0.0620±0.012，and was significantly higher than that of the control group（0.0504±0.009，P<0.05）;which in the respiratory alkalosis group was 0.0476±0.007, there was no signifacant difference between ALG and CG （P>0.05）. CONCLUSION　The fluorescent measurements of H+/K+ exchange in primary cultured IMCD cell monolayers of rabbit kidney has many benefits which are convenient manipulation, stable and credit result, economy and safety , this method should further be popularized.
