Background:
In acute and chronic renal inflammatory diseases, the activation of inflammatory cells is involved in the defect of erythropoietin (EPO) production. Ras guanine nucleotide-releasing protein-4 (RasGRP4) promotes renal inflammatory injury in type 2 diabetes mellitus (T2DM). Our study aimed to investigate the role and mechanism of RasGRP4 in the production of renal EPO in diabetes.
Methods:
The degree of tissue injury was observed by pathological staining. Inflammatory cell infiltration was analyzed by immunohistochemical staining. Serum EPO levels were detected by enzyme-linked immunosorbent assay, and EPO production and renal interstitial fibrosis were analyzed by immunofluorescence. Quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression of key inflammatory factors and the activation of signaling pathways. In vitro, the interaction between peripheral blood mononuclear cells (PBMCs) and C3H10T1/2 cells was investigated via cell coculture experiments.
Results:
RasGRP4 decreased the expression of hypoxia-inducible factor 2-alpha (HIF2A) via the ubiquitination–proteasome degradation pathway and promoted myofibroblastic transformation by activating critical inflammatory pathways, consequently reducing the production of EPO in T2DM mice.
Conclusion
RasGRP4 participates in the production of renal EPO in diabetic mice by affecting the secretion of proinflammatory cytokines in PBMCs, degrading HIF2A, and promoting the myofibroblastic transformation of C3H10T1/2 cells.

Objective To detect anti-HCV in serum of hepatic disease patients by performing the confirmatory test, and further to confirm HCV infection. Methods Two recombinant immunoblot assays (CWT and CHIRON RIBA HCV 3.0 Strip Immunoblot Assay) were used respectively to detect anti-HCV in 477 human serum samples, which comprised 350 HCV-infected patients' specimens, 7 none-A none-E hepatitis specimens, 30 HBV-infected patients' specimens, 30 hepatitis E virus infected patients'specimens, and 60 specimens drawn from blood donors. The latter three groups served as controls. Results A total of 120 control non-HCV-infected patients' specimens were negative when tested by both assays. Among 350 HCV-infected patients, 341 were positive and 9 were indeterminated by CWT assay; 343 were positive and 7 were indeterminated by CHIRON RIBA HCV 3. 0 SIA. Seven none-A none-E hepatitis specimens tested by both assays turned out to be 2 positive, 4 negative and 1 indeterminate. The consistency rate of these two assays was 99. 16% (Kappa=0.98). Conclusion CWT assay is highly coherent with CHIRON RIBA HCV 3.0 SIA assay in the methodology of anti-HCV antibody detection, which can be applied in the determination of HCV infection among none-A none-E hepatitis patients.

Objective To explore the characteristics and clinical significance of CD+4 CD+25 Regulatory T lymphocytes and T cell subsets in peripheral blood and malignant pleural effusion from lung cancer patients. Methods Flow cytometry was used to detect the percentage of CD+4 CD+25 regulatory T cells and T cell subsets in peripheral blood from 68 lung cancer patients and 56 healthy persons, and in pleural effusion from 32 lung cancer patients with malignant effusion. Results T lymphocyte subsets in peripheral blood of lung cancer patients in different periods were expressed differently. The percentage of CD+4 CD+25 regulatory T cells in peripheral blood were (19.52±3.32)%, (27.28±8.26)% and (32.31±15.60)% in Ⅰ+Ⅱ, Ⅲ and Ⅳ period lung cancer patients, respectively, and were higher than that of healthy volunteers (11.12±3.32) % (t =31.0040, -7.9688, -4.9770, P <0.05). In the lung cancer patients with malignant effusion, the percentage of CD+4 CD+25 regulatory T cells in the pleural effusion was higher than that in the peripheral blood [(34.12±18.63) % vs (26.36± 16.25)%, t =21.164, P<0.05]. In the lung cancer patients with malignant effusion ,the percentages of CD+4 in peripheral blood and pleural effusion were (25.32±13.45) % and (34.68±12.34) %, were lower than that in healthy volunteers (t =7.3104, 4.8818, P<0.05), the percentages of CD+56 were (8.24±7.38) % and(11.23± 7.65) %, CD+4/CD+8 were (1.02±0.56) % and (1.32±0.82)%, were lower than (18.23±9.23) % and (1.89± 0.32) % in healthy volunteers, respectively, (CD+56: t =-14.7549, -11.7216; CD+4/CD+8: t =-24.78,-4.4564, P<0.05). Conclusion The relative increase of CD+4 CD+25 Regulatory T cells may be related to immunosuppression and tumor progression in patients with lung cancer. Conclusion The relative increase of CD+4 CD+25 regulatory T cells may be related to immunosuppression and tumor progression in patients with lung cancer.
