Methods: By use of proteomics technology, the serum protein serum proteome of the control group, model control group, Duxil and each observation group were observed for 2-DE gel pattern matching, and the difference in the relative content of 2 times was chosen for the differentially expressed proteins. Identification of differentially expressed proteins by MALDI-TOF MS/MS, the authors further analysis the phosphorylation, subcellular localization, interaction, direct regulation, and transmembrane of the differences proteins by the way of bioinformatics analysis. Sixty SPF level SD rats elected in diabetic rats model group (abbreviated as DM group) were be randomly divided into 5 groups based on random number sheet, namely model control group, positive drug control group (Du-ke-xi group) and Mai-tong-fang high, medium and low dose group respectively. In addition, set of normal control group. 10 rats in each group. Results: By Coomassie brilliant blue staining, identified 51 differential protein spots dug from 2-D gel by mass spectrometry, successfully identified 13 non-redundant proteins. Most of the identified proteins were secreted protein and belong to different protein families. There were about 12 proteins have the transmembrane region from the authors’ result, ten of them were plasma membrane proteins. Conclusion: It’s suggesting that 13 differential proteins is most likely the protein response to GEPRB in vivo, these proteins may play key role for the treatment of GEPRB to Diabetes deafness. The two highly differentially expressed proteins Apolipoprotein E (apoE) and C3 may be a potential drug target of GEPRB.展开更多

文摘BACKGROUND Hepatitis C virus(HCV)is a leading cause of worldwide liver-related morbidity and mortality.The World Health Organization released an integrated strategy targeting HCV-elimination by 2030.This study aims to estimate the required interventions to achieve elimination using updated information for direct-acting antiviral(DAA)treatment coverage,to compute the total costs(including indirect/societal costs)of the strategy and to identify whether the elimination strategy is cost-effective/cost-saving in Greece.AIM To estimate the required interventions and subsequent costs to achieve HCV elimination in Greece.METHODS A previously validated mathematical model was adapted to the Greek HCVinfected population to compare the outcomes of DAA treatment without the additional implementation of awareness or screening campaigns versus an HCV elimination strategy,which includes a sufficient number of treated patients.We estimated the total costs(direct and indirect costs),the disability-adjusted life years and the incremental cost-effectiveness ratio using two different price scenarios.RESULTS Without the implementation of awareness or screening campaigns,approximately 20000 patients would be diagnosed and treated with DAAs by2030.This strategy would result in a 19.6%increase in HCV-related mortality in2030 compared to 2015.To achieve the elimination goal,90000 patients need to be treated by 2030.Under the elimination scenario,viremic cases would decrease by78.8%in 2030 compared to 2015.The cumulative direct costs to eliminate the disease would range from 2.1-2.3 billion euros(€)by 2030,while the indirect costs would be€1.1 billion.The total elimination cost in Greece would range from€3.2-3.4 billion by 2030.The cost per averted disability-adjusted life year is estimated between€10100 and€13380,indicating that the elimination strategy is very costeffective.Furthermore,HCV elimination strategy would save€560-895 million by2035.CONCLUSION Without large screening programs,elimination of HCV cannot be achieved.The HCV elimination strategy is feasible and cost-saving despite the uncertainty of the future cost of DAAs in Greece.
文摘The physico-chemical exchanges between hydrothermal fluids and the host rock are usually controlled by elemental interaction effects.A criterion-based backward elimination approach applies the iterative regression analysis and analysis of variance to investigate the geochemical features of the polymetallic Glojeh(Au-Ag-CuPb-Zn)deposit in NW Iran.A statistical definition of the elemental interaction effects(X(i-j)^2,Xi×Xj)could elucidate the relationship between variables and the performance of a full quadratic polynomial model(QPM).The model optimization procedure was carried out by the removal of insignificant predictors(P value 95%CL)based on R^2(pred.)criterion.In order to straighten the convergent trend with R^2 and R^2(adj.),R^2(pred.)gradually increased from 0%to 77.8%by 15-steps optimization.The miniature-scale geochemical changes indicate double ordinal Au(Ag,Pb)and Au(Ag,Zn)interactions within the vein and host rock,in QPM.Results show that the Au(Pb-Zn)commonly presents ordinal effect at the vein and disordinal interaction at the host rock.This ordinal-disordinal interaction revealed that elements Pb and Zn have similar geochemical features during mineralization.In addition,Akima's polynomial contour map confirms the results from Pb-Zn interaction effects by dependency tracing between Au-Pb-Zn at different populations.However,it is noteworthy that Pb and Zn occur together in the second phase of Pb-Zn-Cu±(Ag±Cd)sulfide mineralization at Glojeh,which implies intergrowth and interaction of Pb-Zn on Au concentration.Pb and Zn demonstrate relatively high mobility and are generally concentrated in the near surface zones.Nb is an immobile element during alteration and high content Hg zone is mainly restricted to narrow stripes above ore vein and veinlets.
文摘Objective: to analyze the effect of Huatan Quyu Tongmai Decoction in the treatment of unstable angina pectoris of coronary heart disease. Methods: from January 2020 to January 2021, 110 patients with unstable angina pectoris of coronary heart disease were selected and divided into two groups. The control group was treated with western medicine, and the research group was treated with Huatan Quyu Tongmai Decoction. The therapeutic effects of the patients were compared. Results: the total effective rate of the study group was higher;After treatment, the TCM symptom score of the study group was lower;After treatment, the improvement of angina attack in the study group was greater than that in the control group. After the treatment, the improvement of cardiac function in the study group was better than that in the control group, and the smoking group was more satisfied with the treatment content, with statistical significance (P<0.05). Conclusion: during the treatment of patients with unstable angina pectoris, Huatan Quyu Tongmai Decoction can help patients to further achieve the relief of clinical symptoms. It has positive value for the improvement of patients' cardiac function and health protection, and is worthy of popularization and application.
