Objective To explore the CD4 + CD25 + Foxp3 + regulatory T cell percentage and plasma levels of soluble CD25 molecules in peripheral blood of septic patients and their clinical value through prospective study. Method A total of 37 septic patients and 15 non-infectious SIRS patients, who conformed to the criteria of SIRS and sepsis which proposed by American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference ( ACCP/SCCM ) in 1997, were collected in ICU of Ruijin Hospital ( Shanghai Jiaotong University) from February 2009 to February 2010. Twenty-four health people were from Medical Center of Ruijin Hospital, who were excluded infection and (or) autoimmune diseases. There were 26 male and 11 female in sepsis group, average age ( 61.67 ± 11.87 ) years old; 8 male and 7 female in SIRS group, average age (67.06 ± 12.57)years old; 14 male and 10 female in health control, average age (56.54 ± 6.37 )years old. All selected patrents were excluded the autoimmune diseases and (or) patients within recent (30 days) had used or now used immunosuppressive agents. We therefore measured the Treg cell percentage in peripheral blood by Flow Cytometry and the plasma levels of IL-2sRa, IL-4, IFN-γ by ELISA. The data were analyzed by analysis of variance or nonparametric Kruskal-Wallis H test. Results ① The percentage of CD4 + CD25 + Foxp3 + regulatory T cells among septic patients, SIRS patients, and control group was: ( 66.82 ± 21.79 ) %, ( 51.79 ± 21.79 ) %, ( 56.45 ± 10. 68 ) %, respectively. septic patients showed the highest percentages of CD4 + CD25 + Foxp3 + regulatory T cell among CD4 + CD25 + T cells(P ＜ 0.05 ). ② The plasma levels of soluble CD25 in septic patients (425. 619 ± 270.12 ) were significantly higher than SIRS patients (381. 664 ± 189.83) and the control group ( 164. 1 32 ± 56.37 ) ( P ＜ 0.05 ). ③ The correlation analysis between the concentration of soluble CD25 molecules in plasma and the ratio of CD4 + CD25 + Foxp3 + regulatory T cells to CD4 + CD25 + T cells showed Spearman correlation coefficient =0.390, P = 0.003 ( P ＜ 0.05 ). Conclusion: the expression of natural regulatory T cells characteristically increased in septic patients. And the levels of soluble CD25 in peripheral blood were related to the percentages of natural regulatory T cells, which simplified the assessment of the immune status in Septic patients.

Objective To explore the phenotypic characteristics of T lymphocyte subsets in the peripheral blood (PB) of Patients with rheumatoid arthritis.Methods forty-seven patients with ankylosing spondylitis (AS) and 36 health control were selected as our subjects.The patients were divided into definite Diagnosis AS group and potential AS group according to symptom and X-ray,flow cytometry was applied to measure T lymphocyte subsets and HLA-B27 of peripheral blood.At the same time,the levels of ESR,CRP and IgA were also measured.The correlation between T lymphocyte subsets and CRP HLA-B27,IgA level was analyzed.Results There was no significant difference between The definite diagnosis AS patients and healthy controls regarding of the percentages of CD3 + cells in peripheral blood,However the percentage of CD4 + cells in definite diagnosis AS patients was significantly increased than that of healthy controls (P ＜ 0.05).The ratio of CD4 +/CD8 + cells was 3.80 ± 0.28 in AS patients,higher than that of potential AS patients.T lymphocyte subsets were showed an increase tendency as the increase the level of CRP,IgA.Conclusion Lower CD8 + cell and higher CD4 + cell were showed in the peripheral blood of AS patients,which was correlated with the disease activity and suggesting T cells might be involved in the pathogenesis process of AS.Meanwhile our data indicated that the immune response might be a susceptible factor of AS and early detection of T lymphocyte subsets might provide a diagnosis and treatment basis for diagnosis of AS.Therefore the disorder of T lymphocyte subsets might play an important role in the development of rheumatoid arthritis.

Objective To evaluate antibiotic therapy for the treatment of intraabdominal infection secondary to severe acute pancreatitis.Methods 39 SAP patients with intraabdominal infection were devided into 2 groups: early infection group (early group) and late infection group (late group) according to the onset time of infection. All patients received imipenem and or surgical treatment, and results were compared between the two groups. Results 83 strains of pathogen were isolated among which Gram negative bacteria accounting for 84%, with a ratio of sensitivity to imipenem of 80%; Gram positive bacteria taking up 16%, all were resistant to imipenem. The cure rate was 53% in eraly group and 86% in late group(P=0.02); The rate of bacteria clearance was 47% in early group and 82% in late group(P=0.02). The survival rate of patients in early group was 77% and in late group was 95%(P=0.08); The reinfection rate in early group was 58% and in late group was 37%(P=0.16). Conclusion Imipenem is effective in the treatment of intraabdominal infection secondary to severe acute pancreatitis,and repeated surgical intervention is still necessary for patietns in early infection group.
