Objective To review the kidney transplantation performed in our center and analyze the risk factors affecting long-term allografts survival. Methods Thirty two relative variables were analyzed by SAS statistical software. Using Log-Rank method, the influence of these variables on short and long-term grafts survival was investigated. A Kaplan-Meier analysis was used to estimate the 1-, 3-, 5-, 10-year graft survival rate and its half-life. Proportional hazards regression analysis (Cox model) was used to assess and rank the relative risk of potential variables.Results The 1-year, 3-year, 5-year, 10-year grafts survival rate was 82.5 %, 75.2 %, 65.5 % and 48.4 % respectively. When excluding the patients died with functioning grafts, the 1-year, 3-year, 5-year, 10-year grafts survival rate was increased to 91.0 %, 82.0 %, 75.9 %, 68.5 %, 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 grafts survival were identified as: renal function and duration of which become normal, cold-ischemia time, acute rejection, delayed grafts function, immunosuppressive regimen, complication, infection, the method of anti-rejection therapy. A Cox model multivariate analysis showed that there were 18 factors affecting graft survival.Conclusion New immunosuppressive agent not only has significantly increased short-term graft survival, but also prolonged the long-term survival. Making assurance to get high quality donor organ and minimizing the death with graft function may be the most feasible way to prolong a graft survival at present.

Polypoidal choroidal vasculopathy(PCV) is a common disease of the retina,the disease is more found in colored race.In China,the mainly nosogenic population is the female about 60 years old.The pathogenesis of PCV is unknown and there is no specific medicine at present.The funduscopic present is orangered lesions,bleed and exudation.Indocyanine green angiography(ICGA) could make a definite diagnosis of PCV.In recent,the main treatment of PCV includes photodynamic therapy,intravitreal anti-VEGF therapy,surgery for treatment of complications and combined therapy.We review the treatment and diagnosis of PCV,and propose the further research direction.

Objective To explore the influence of renal allograft recipient cytokine and cytokine receptor gene polymorphisms on the infection after renal transplantation. Methods (1) 126 cases of cadaveric renal allograft recipients were divided into two groups according to the presence or Absence of infection in 6 months after renal transplantation: infection group and un infection group. The distribution of 22 polymorphisms in 13 cytokines and cytokine receptors gene were compared between two groups as well as latent factors affecting the onset of infection. The production types of IL 10, TNF ?, TGF ?1 and IL 6 were analyzed; (2) All recipients were stratified into two conditions: presence of rejection or Absence of rejection. Previous positive gene polymorphisms were compared between infection group and un infection group under two conditions. Results (1) The incidence of acute allograft rejection was significantly higher in infection group than in un infection group. In infection group, the genotype frequency of IL 1? 889 C/C, IL 1? 511 C/C, IL 1?+3962 C/T or T/T, and the higher production type frequency of TGF ?1 were significantly higher than those in un infection group. (2) In the recipients without acute rejection, the genotype frequency of IL 1? 511C/C was significantly higher in infection group than in un infection group; whereas in those with acute rejection, the genotype frequency of TGF ?1 (codon10 codon 25) CG/TG and frequency of TGF ?1 with high production were significantly higher than those in no infection group. Conclusion This study identified recipient genotype of IL 1? 889 C/C, IL 1? 511 C/C, TGF ?1(codon10 codon 25) CG/TG and higher production type of TGF ?1 gene as major risk factors for the onset of infection after renal transplantation as well as presence of acute allograft rejection, which might affect the action of these gene polymorphisms.
