BACKGROUND:Long-term use of corticosteroids (hereinafter referred to as hormone) after renal transplantation could obviously lead to adverse reactions. Immunosuppressive regimen with less and no hormone has been a hot focus in the study of renal transplantation al over the world. However, reduction or withdrawal of hormones has a certain risk. At present, there is no unified scheme. Because urine protein can be immediately detected after tubular injury, to monitor urine protein can find the renal dysfunction after transplantation in recipients undergoing renal transplantation, which can gain time for clinical therapy. OBJECTIVE:To discuss the influence of hormone (prednisone) removal on the occurrence of urine protein in recipients undergoing renal transplantation. METHODS:A total of 35 recipients undergoing renal transplantation after removal of prednisone received immunosuppressive regimen of cyclosporine A or tacrolimus+mycophenolate mofetil bivalent. Initial dose of prednisone was 30 mg/d, and then gradual y reduced by 5 mg per week, and withdrawn at 1 month after renal transplantation. There were 16 cases in cyclosporine A group and 19 cases in tacrolimus group. Urine protein was measured and quantified at 3, 6, 12 and 24 months after renal transplantation and 3, 6 and 12 months after addition of prednisone in both groups. Simultaneously, serum creatinine, fasting glucose, body mass increases, the rate of acute rejection, infection, patient/graft survival at 2 years after renal transplantation and urine protein at 24 hours before and after adding hormone were recorded. RESULTS AND CONCLUSION:For the two groups, urineα1-microglobulin started to rise after 6 months of removal of prednisone. Urinary microalbumin, urinaryα1-microglobulin, and urinary transferrin ascended obviously at 12 months. Urinary protein was positive in five cases of cyclosporine A group and in three cases of tacrolimus group. At 24 months, urinary microalbumin, urinaryα1-microglobulin, urinary transferrin and urinary IgG ascended obviously. Urinary protein was positive in cyclosporine A group with 11 cases and in tacrolimus group with 10 cases. 24-hour urinary protein quantity was more than 1 g in every case. On this base, we made the patients to take more prednisone for 6 months, so urineα1-microglobulin and urinary microalbumin began to descend. Each group had one case of positive urinary protein turning to negative. Twelve months after the adjustment of the prednisone, urinary microalbumin, urinaryα1-microglobulin, and urinary transferrin descended respectively. Positive urinary protein turned into negative:in cyclosporine A group with two cases and in tacrolimus group with three cases. 24-hour urinary protein quantity was around 0.7 g. Two years after renal transplantation, serum creatinine and acute rejection rates were higher in the cyclosporine A group than in the tacrolimus group (P<0.05). No significant difference in fasting glucose, body mass increase, infections, and patient/graft survival was detectable between both groups. Results suggested that removal of prednisone greatly affected urine protein in recipients undergoing renal transplantation. In particular, at 2 years after renal transplantation, urinary microalbumin, urinaryα1-microglobulin, urinary transferrin and urinary IgG ascended obviously, and the security needs further research.

To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

Most Chinese medicine has good clinical efficacy and application. However, the material basis is vague for the lack of basic research, the value of Chinese medicine is hard to reflect for the low technology level and product quality is difficult to maintain for the quality control indicator selection is incorrect. Chinese medicine Jinfukang oral liquid is a typical product of Chinese medicines. Jinfukang oral liquid was selected as a model drug in this article. Based on the overall concept and systems theory of traditional Chinese medicine, the research idea and technology system for modern Chinese medicine secondary exploitation was formed. The system includes three parts, for the first, basic research to make clear the components structure and their action mechanism, for the second, technology upgraded to optimize process and improve the product quality, for the last, exploring the associated industry to form the industrial chain. The research ideas and technology system based on the material basis research and development of modern Chinese medicine, guided with component structure in Chinese medicine and aimed clinical needs. This research ideas and technology system provides strategies and methods for the development of modern Chinese medicine secondary exploitation.

Objective To investigate the effects of exercise training(ET)on the expression of glucogen synthase kinase 3 bate(GSK 3?)in the adipose tissues of insulin resistant(IR)rats on a high fat diet(HFD). Methods Thirty male Wistar rats were randomly divided into a control group(n=10)and a model group(M group,n=20).Insulin resistance was established by feeding a HFD to the M group for 4 w,while rats in the control group were fed a normal diet.The IR rats were then randomly divided into two subgroups:an IR group and an ET group.All rats in the IR and ET groups were fed a HFD,but ET was administrated to the ET group for 6w.The expres- sion of GSK 3?protein in the rats'epididymis adipose tissue was detected using Western blotting,and body weight (BW),the concentrations of serum triglyceride and cholesterol(TG and TC),fasting plasma glucose(FPG)and serum insulin(FINS),as well as insulin sensitivity index(ISI)were regularly detected.Results Compared with the con- trol group,BW and the concentrations of serum TG and TC,FPG and FINS in the model group were significantly in- creased(P＜0.05),while ISI was decreased(P＜0.01).Compared with the control group,there was no difference in GSK 3 protein expression in the ET group,but the expression of GSK 3?protein in the ET group was obviously de- creased in comparison with that in the IR group(P＜0.05).Conclusion ET can ameliorate IR by decreasing GSK 3?protein expression in adipose tissues and enhancing the ingestion of glucose and the synthesis of glycogen.

Objective:To investigate the effect of metformin and arsenic trioxide on KG1a cells proliferation of acute myeloid leukemia and its possible mechanism.Methods:CCK-8 method was used to detect the killing effect of metformin,arsenic trioxide and combined application on KG1a cells.Annexin V-FITC/P1 Dual Stain Flow Cytometry was used to detect the effect of combined application on apoptosis of KG1 a cells.Western blot was used to detect the expression of intracellular apoptosis-,autophagy-related protein.Results:Metformin and arsenic trioxide alone or in combination could inhibit the proliferation of KG1 a cells and induce apoptosis of KG1 a cells,and the proliferation inhibition rate and apoptosis rate in the combined drug group were higher than those in the drug group alone(P＜0.05).The combination of drugs induced upregulation of Caspase 8 protein and P62 protein expression and was higher than that in the drug group alone(P＜0.05).Conclusion:Metformin can synergize with arsenic trioxide to kill KG1a cells,and its mechanism of action may be related to inducing apoptosis and enhancing autophagy.
