Rheumatoid arthritis (RA) is an autoimmune disease characterized by the accumulation and proliferation of inflammatory cells in the synovial (joint) lining.By investigating RA pathologic processes and also through experimental models where immune complexes (inflammatory sediments) play a fundamental role.Many other autoantibodies have then come to our knowledge to be associated with the disease.Though it remains unknown the autoimmune pathology of B cells and why the clones of autoreactive B cells survive and proliferate in RA patients,but no doubt these autoantibodies represent a very useful tool in both diagnostic and prognostic terms.In joint synovial fulid,B cells also secrete cytokines,which can be interacted with other cells.B cells express IL-13 receptor a1 (IL-13Ra1),IL-13 can induce CD23 expression on B cells and promote proliferation of naive B cells. In addition,IL-13 is a cytokine which is produced mainly by activated T helper cell 2 (Th2 cells),it can inhibit the production of pro-inflammatory factor and chemokines,and has a certain relationship with the differentiation of B cells. Therefore,it is necessary to summarize the mechanims of RA pathogenesis related with B cells and IL-13,which has great significance in the diagnosis,treatment and basic immunology research of autoimmune diseases such as RA.

BACKGROUND:Fol ow-up researches have shown that there is no statistical y difference in safety between kidney donor and healthy person after kidney transplantation, even the donors wil have better life quality. OBJECTIVE:To evaluate the safety of living-related kidney transplantation in living kidney donors. METHODS:Ninety-four cases of kidney donors received 1-10 years fol ow-up through regular clinical fol ow-up, telephone fol ow-up and regular renal patients self-help groups to compare the changes of serum creatinine, hematuria, proteinuria and blood pressure and lipid level in the donors before and after kidney transplantation. RESULTS AND CONCLUSION:The serum creatinine was significantly increased after nephrectomy (P<0.01), but al the donors had normal serum creatinine levels and remained stable. There was no significant difference in serum creatinine level between the latest fol ow-up and discharge (P>0.05). After nephrectomy, three cases (3.2%) suffered from hematuria, two cases (2.1%) had proteinuria, and improved after rest;six cases (6.4%) were subject to hypertension and six cases (6.4%) to hyperlipidemia. Al of the donors were alive. The living donor nephrectomy is feasible and safe. Preoperative assessment and long-term postoperative fol ow-up can guarantee the safety of the donors.

Objective To investigate the correlation between urine levels of IP-10,Mig,OPG and the occurrence of renal allograft rejection.Methods As a retrospective nested case-control study,biopsy confirmed acute rejection reaction by 20 cases was rejection group,and recovery of renal function in kidney transplant after the elect good by 20 cases was control group.morning urine was tested of IP-10,Mig and OPG level of the two groups within 30 d after transplantation.The advantage was taken of the Luminex 2000 test platform,through PlexMark triple kidney injury marker kit to detect the daily urine of recipients.Results The rejection group's urinary IP10 wa (394.7 ± 67.3)ng/L,significantly higher than that in the control group of (10.9 ± 3.8) ng/L (P<0,05).Urine Mig level of rejection group was (443.0 ± 88.9) ng/L,and the control group was only (15.7 ± 6.99)ng/L.Rejection group was significantly higher than that in the control group (P<0.05).Urine OPG peak levels,the difference between the two groups was not statistically significant.Rejection group in the rejection period urinary IP-10 and Mig levels were significantly non-exclusion period,the difference was statistically significant (P<0.01) higher than its level at different times with serum creatinine concentration showed obvious correlation,IP-10 with serum creatinine of correlation coefficients (R2)=0.8673,P<0.01,Mig and serum creatinine R2 =0.7951,P<0.01,IP-10 and Mig change time earlier than serum creatinine,to the exclusion of the before and after OPG differences no statistically significant.Conclusion The increasing of IP-1O and Mig content in the urine is associated with acute renal allograft rejection,which is an early reflect of subclinical tubular injury.And its changes as early as elevated serum creatinine,is expected to become independent indicators to predict acute rejection reaction occurs.

Objective:To analyse the biological function of anti-IL-6Rβ(gp130) monoclonal antibody and its regulatory effect on IL-6 signaling.Methods:Biological characteristics of anti-IL-6Rβ(gp130) mAb were assessed by Western blot analysis, capture ELISA and peptide ELISA .The phosphorylation of STAT 3 was tested by Western blot analysis in IL-6-stimulated U266/RA-FLS/RA-PBMC with or without anti-IL-6Rβ(gp130) mAb treatment.Results:3 strains of mouse anti-human gp130 mAb were with high affini-ty and different binding epitopes , the kaff of 10A1 was 2.62E-10.In U266, RA-PBMC and RA-SFMC, IL-6 signaling highly activated STAT3 which could be inhibited by anti-gp130 mAb.Conclusion: Anti-IL-6Rβ( gp130 ) mAb might have different binding epitopes and could affect IL-6 stimulated phosphorylation of STAT3, which provides a preliminary experiment for analyse the correlation of IL-6 signaling and RA .

OBJECTIVETo review kidney transplantation in the center and analyze the risk factors affecting long-term allograft survival.
METHODSThirty-two relative variables were analyzed with SAS statistical software. Using Log-rank method, we investigated influence of these variables on short-and long-term survival of grafts. Kaplan-Meier analysis was used to estimate the 1-, 3-, 5-, 10-years graft survival rates and half-life. Proportional hazards regression analysis (Cox model) was used to assess and rank the relative risk of potential variables.
RESULTSThe 1-, 3-, 5-, 10-years graft survival rates were 83%, 75%, 66% and 48%. After excluding the patients died with functioning grafts, the 1-, 3-, 5-, 10 years grafts survival rate increased to 89%, 82%, 75% and 69%, respectively. The mean half-life was 8.78 +/- 0.14 and 14.09 +/- 0.20 years, respectively. By Log-rank analysis, factors affecting short- and long-term graft survival were identified as: renal function, duration of graft function became normal, cold-ischemia time, presence of acute rejection, delayed graft function, immunosuppressive regimen, complication, infection, anti-rejection therapy. Cox model multivariate analysis showed that there were 18 factors affecting graft survival.
CONCLUSIONSNew immunosuppressive agents not only significantly increase short-term graft survival, but also have the better long-term outcome tendency. Making assurance to get high quality donor organ and minimizing the death with graft function may be the most feasible way to prolong graft survival at present.

Prostate cancer (PCa) is one of the most common malignant tumors in the male genitourinary system. The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway is a carcinogenic pathway responsible for the migration, proliferation, and drug resistance of various cancers. In recent years, as the research on the pathogenesis of PCa is deepening, the role of the PI3K/Akt signaling pathway in the development of PCa has attracted much attention. Traditional Chinese medicine, comprehensively regulating multiple components, targets, and pathways, has shown great potential in the treatment of PCa. This article reviews the research progress of traditional Chinese medicine targeting the PI3K/Akt signaling pathway in the treatment of PCa and discusses the expression of the PI3K/Akt signaling pathway in PCa, which involves inhibiting apoptosis of PCa cells, promoting the cell cycle, invasion, and migration of PCa cells, promoting tumor tissue angiogenesis, and mediating the androgen receptor. Additionally, it summarizes the single Chinese medicines that target and regulate this pathway, including Hedyotis diffusa, Taxus chinensis, Bovisc Alculus, and Atractylodis Macrocephalae Rhizoma. The active ingredients of these Chinese medicines mainly include flavonoids, alkaloids, terpenes, polyphenols, lignans, and other compounds. The Chinese medicine compound prescriptions targeting the PI3K/Akt pathway mainly include Wenshen Sanjie prescription, Jianspi Lishi Huayu prescription, Yishen Tonglongtang, Qilan prescription, Xihuangwan, and modified Shenqi Dihuangtang. This review is expected to provide a scientific basis for deeply understanding the pathogenesis of PCa and identifying potential therapeutic targets, as well as to provide new ideas for clinical research and drug development for PCa.
