Objective To evaluate the clinical value of detecting serum underglycosylated IgA1 in diagnosis and differentiation of lgA nephropathy (IgAN). Methods Serum underglycosylated IgA1 was isolated by microspincolumn coupled with vicia villosa lectin (VVL) from 48 cases with IgAN and 43 cases with other primary glomemlonephritis. All the patients were diagnosed by renal biopsy. Sera from 20 healthy persons were used as control group. After isolation, the eluant with rich underglycosylated lgAl was detected by incubation with biotin- labeled horseradish peroxidase (HRP) and Helix aspersa (HAA, recognizing N-acetylgalactosamine specifically)in enzyme-linked immunosorbent assay (ELISA). The sensitivity and specificity of diagnosis and differentiation of IgAN with elevated serum underglycosylated IgA1 were analyzed. Results The level of serum underglycosylated IgA1 in IgAN patients [(83.7±41.0) U] was significantly higher than that in healthy control group [(52.6±22.9) U] and the patients with other primary glomerular diseases[(49.2±27.3) U] (all P<0.01). Twenty-two cases of non-IgA mesangial proliferative glomerulonephritis accounted for 51% of other primary glomerular disease, whose underglycosylated IgA1 level [(47.6±21.5 ) U] (all P<0.01 ) was significantly lower as compared to IgAN patients. Taking the renal biopsy diagnosis as golden diagnostic criteria, the ROC curve was performed. The area under the curve was 0.797 with a standard error 0.047 (P<0.01). The sensitivity as a diagnostic test was 72.9%, with specificity 72.1% and accuracy 72.5%. Conclusion Detection of serum underglycosylated lgAl level by mierospineolumn method and ELISA assay has certain clinical value in diagnosis and differentiation of IgAN.

ObjectiveTo explore the expression of CD3+ CD8+ human leukocyte antigen (HLA)-A2+T lymphocytes with specificity to the different hepatitis B virus (HBV) peptides in the peripheral blood mononuclear cells (PBMC)from the patients with hepatitis B associated hepatocellular carcinoma (HCC).MethodsThe HLA-A2+ PBMC from four patients with hepatitis B associated HCC were incubated with five HBV/HLA-A2 pentamers respectively,which were HBV sAg (FLLTRILTI),HBV sAg (GLSPTVWLSV),HBV sAg (WLSLLVPFV),HBV core (FLPSDFFPSV),and HBV pol (FLLSLGIHL),as well as anti-CD3-pacific blue and anti-CD8-fluorescein isothiocyanate (FITC).Then,HBV/HLA-A2-CD3-CD8 positive cells were detected by flow cytometry. The monoclonal HBV/HLA-A2-CD3-CD8+ cells were acquired by fluorescenceactivated cell sorter,and cultured and identified by flow cytometry.The anti-HBV specific T lymphocytes were then cultured with HepG2 (HLA-A2+ ) cells and the release of interferon γ (IFN-γ)were determined by enzyme-linked immunosorbent assay (ELISA),Res(a)ltsThe percentage of antiHBV T lymphoeytes with specificity to GLSPTVWLSV in total CD8+ T lymphoeytes from four patients with hepatitis B associated HCC was 1.44%±0.04%,which was higher than those to other four HBV antigen peptides (0.68%±0.08% of FLLTRILTI,1.06%±0.09% of FLPSDFFPSV,0.56% ±0.04% of FLLSLGIHL,and 0.46% ±0.08% of WLSLLVPFV) (t=0.001,P<0.05).The two lines of monoclonal cell with specificity to GLSPTVWLSV both exhibited high level of IFN-γ expression after incubated with hepatic carcinoma cell line HepG2 (HLA-A2+)with HBV GLSPTVWLSV peptide.ConclusionsCD3+ CD8+ HLA-A2+ cells with specificity to the different HBV peptides exist in PBMC of patients with hepatitis B associated HCC.The expression level depends on HBV antigen peptide sequences and genomic sites.

OBJECTIVEEpstein-Barr virus (EBV) is a common causative agent of infectious mononucleosis (IM) and capable of efficiently immortalizing primary B cells into continuously growing lymphoblastoid cells in vitro. As B cell activation antigen, CD23 expression is induced by EBV infection of B cells and remains constitutively expressed at high levels in virtually all EBV-immortalized cells, which have been strongly linked to the development of B-cell lymphoproliferative disease and lymphoma. Whereas previous studies were performed in vivo in animals or ex vivo cultures, the present study aimed to explore the role of EBV-immortalized cells (CD23(+)/CD19(+)) in vivo analysis of children with EBV-IM.
METHODSIn a prospective trial, a group of 30 patients with IM (18 boys and 12 girls) with mean age of 3.9 +/- 1.3 years (range 6 months to 8 years) were enrolled. Clinical diagnosis of IM was confirmed based on fever, lymphadenopathy, splenomegaly, lymphocytosis (> 50%), atypical lymphocytes (> 10%) in blood smears and the elevated levels of IgM antibody against EBV capsid antigen. The day of onset of fever was recognized as day 1 of illness. Blood samples taken during acute (3 - 5 days), early convalescent (about 11 - 15 days) and convalescent phase (about 30 - 45 days) were analyzed for expressions of CD19(+)/CD23(+), CD23, CD19 on peripheral blood mononuclear cells by flow cytometry (FCM) and was compared with those of control group.
RESULTS(1) The levels of CD23(+)/CD19(+) and CD23 expressions were markedly decreased in acute stage [CD23(+)/CD19(+) (2.22 +/- 1.47)%, (132 +/- 91)/mm(3); CD23 (3.12 +/- 1.88)%, (195 +/- 102)/mm(3)] and in early convalescent stage [CD23(+)/CD19(+) (4.51 +/- 2.25)%, (166 +/- 85)/mm(3); CD23 (5.55 +/- 2.76)%, (231 +/- 130)/mm(3)] in patients with IM as compared with those of the healthy controls [CD23(+)/CD19(+) (6.71 +/- 2.25)%, (215 +/- 68)/mm(3); CD23 (7.85 +/- 3.09)%, (249 +/- 86)/mm(3), respectively]. The earlier the history was, the lower the expressive levels were. The levels of CD23(+)/CD19(+) expressions returned to, but those of CD23 expressions exceeded, normal level in convalescent stage [CD23(+)/CD19(+) (6.72 +/- 2.16)%, (213 +/- 108)/mm(3); CD23 (9.46 +/- 2.73)%, (366 +/- 200)/mm(3)]. (2) There was a positive correlation in the expressions of CD23(+)/CD19(+) and CD23 among the three stages (P < 0.01). The positive correlation between the expressions of CD23(+)/CD19(+) and CD19 only occurred during acute stage (P < 0.01). There was no correlation between the expressions of CD23 and CD19 (P > 0.05).
CONCLUSIONEBV-immortalized cells and CD23(+) cells were inhibited effectively during the acute and early convalescent stage of IM. With the recovery of the disease, they gradually recovered and the levels of CD23 expressions exceeded normal level in convalescent stage.

OBJECTIVEInfectious mononucleosis (IM) is a lymphoproliferative disease caused primarily by the Epstein-Barr virus (EBV) infection. The initial viral infection by EBV occurs in B lymphocytes and is followed by an extensive proliferation of T lymphocytes. Previous studies on immunity to EBV (including IM) have mainly focused on activation of peripheral blood T cells, which are responsible for the lymphocytosis in blood during acute IM. B cells, regarding CD23 as their activation marker, are the target cells of EBV infection. There are few reports on their effect in patients with IM. The role of them during acute IM is not known yet. The present study aimed to explore the action of B cells in patients with IM.
METHODSIn a prospective trial, a group of subjects comprised 22 patients with IM (14 boys and 8 girls) with mean age of 3.48 +/- 0.81 years (range 7 months to 8 years). Clinical diagnosis of IM was confirmed based on fever, lymphadenopathy, splenomegaly, lymphocytosis (> 50%), atypical lymphocytes (> 10%) in blood smears and the elevated levels of IgM antibody against EBV capsid antigen. The day of onset of fever was recognized as day 1 of illness. Blood samples taken during acute (3 - 5 days) and convalescent phase (about 15 days) were analyzed for expressions of CD19, CD19(+)/CD23(+) on PBMC by flow cytometry (FCM) and was compared with those of control group. The number of the days with fever was recorded.
RESULTS(1) The levels of CD19 and CD19(+)/CD23(+) expressions were markedly decreased in acute stage [CD19 (5.63 +/- 2.91)%, (387 +/- 178)/mm(3), CD19(+)/CD23(+) (2.45 +/- 1.87)%, (160 +/- 99)/mm(3)] and in convalescent stage [CD19 (12.49 +/- 5.70)%, (428 +/- 156)/mm(3), CD19(+)/CD23(+) (5.05 +/- 2.79)%, (172 +/- 78)/mm(3)] in patients with IM as compared with those of the healthy controls [CD19 (16.20 +/- 2.80)%, (545 +/- 150)/mm(3); CD19(+)/CD23(+) (7.08 +/- 2.78)%, (249 +/- 136)/mm(3)]. The earlier the specimens were taken after onset, the lower the expressed levels were. (2) There was a positive correlation of the expressions of CD19 and CD19(+)/CD23(+) between acute and convalescent stage (P < 0.01);there was also a positive correlation between the expressions of CD19 and CD19(+)/CD23(+) during acute and convalescent stage (P < 0.01). (3) A negative correlation was found between the duration of fever and the level of CD19 and CD19(+)/CD23(+) in acute stage (P < 0.01).
CONCLUSIONThe results indicate that B cells and CD23(+) B cells were significantly inhibited during the onset of IM in the patients, that with the recovery of the disease, the condition was gradually improved, and that the more evidently the CD19 and CD19(+)/CD23(+) decreased, the more serious the clinical symptoms were and the longer time the recovery needed. The levels of CD19 and CD19(+)/CD23(+) expressions may be useful in diagnosis and predicting the severity.
