OBJECTIVETo understand the risk factors of schistosomiasis transmission in the Three Gorges Reservoir Area (TGRA) and to provide evidence for the development of control strategy.

METHODSApproaches including epidemiology, immunology and field survey were applied to investigate the potential risk factors which would involve the importation of infectious resources live mobile and migrant population, and livestock in the reservoir area. Meanwhile, observation on survival and reproductive status of snail under simulation habitats was also carried out, using ecological methods on snails. Strategy in preventing the spread of snail as infectious resources was also provided.

RESULTS175 mobile people from schistosomaisis endemic area of were tested and one person showed immunology tests positive with indirect hemagglutination test (IHA) and circumoral precipitin test (COPT), with a positive rate of 0.57%. Through the two-year period under observation, data showed that the snails with ribbon/smooth shells could survive and reproduce under habitats of simulation.

CONCLUSIONSOnce the infectious resource of schistosomiasis was introduced into the TGRA, the area became a new schistosomiasis epidemic area in TGRA which called for countermeasures to be taken.

OBJECTIVETo investigate the effect of (AT)n repeat polymorphism of the 3'untranslated region in cytotoxic T-lymphocyte associated antigen 4 (CTLA-4) gene on CTLA-4 mRNA stability and full length (flCTLA-4) and soluble CTLA4 (sCTLA-4) expression in ulcerative colitis (UC).

METHODSflCTLA-4 mRNA in colonic biopsies and sCTLA-4 mRNA stability in peripheral blood mononuclear cells of UC patients were measured by quantitative PCR and half-life, respectively. The protein expression of flCTLA-4 in colonic biopsies and sCTLA-4 in sera of UC patients were determined by immunohistochemistry and enzyme-linked immunosorbent assay, respectively. The polymorphism of CTLA-4 (AT)n repeats in 300 UC and 700 age and sex matched healthy controls was genotyped by fluorescent PCR.

RESULTSAmong the UC patients, sCTLA-4 mRNA expression levels were decreased in active disease compared to non-active disease (P= 0.004). Carriers of the longer alleles of the (AT)n repeats expressed lower levels of flCTLA-4 and sCTLA-4 mRNA and sCTLA-4 protein than those of the shorter alleles in UC (all P< 0.01), and mRNA with long (AT)n repeat alleles has shorter half-life than mRNA with short alleles and, hence, are unstable. The frequency of long allele carriers of CTLA-4 (AT)n repeats was significantly higher in UC patients than in the healthy controls (22.0% vs. 6.3%, P< 0.01, OR= 4.21, 95% CI: 2.79-6.33), and associated with extensive colitis (P= 0.008).

CONCLUSIONCTLA-4 gene expression levels were associated with (AT)n repeat polymorphisms in UC patients. The expression of CTLA-4 mRNA and protein were decreased in carriers of the longer alleles of the (AT)n repeats of CTLA-4 gene. This study suggests that CTLA-4 plays an important role in genetic risk and pathophysiology for UC in central China.

OBJECTIVETo study the expression of MUM-1/IRF4 and its significance in follicular lymphoma.

METHODSNinety-eight cases of follicular lymphoma were enrolled into the study. They were graded according to the 2008 WHO criteria. The expression of MUM-1/IRF4 protein and other markers (CD10, bcl-6, bcl-2 and Ki-67) was studied using tissue microarray and immunohistochemistry.

RESULTSAmongst the 98 cases studied, there were 24 grade 1 cases, 30 grade 2 cases, 26 grade 3A cases and 18 were grade 3B cases. The rates of expression of MUM-1/IRF4, CD10, bcl-6, bcl-2 and Ki-67 (≥ 25%) were 39.8% (39/98), 62.2% (61/98), 80.6% (79/98), 87.8% (86/98) and 50.0% (49/98), respectively. MUM-1/IRF4 predominantly expressed in high-grade follicular lymphoma and showed a significantly positive correlation with lymphoma grade (r = 0.628, P = 0.000) and Ki-67 index (r = 0.473, P = 0.000). MUM-1/IRF4 expression had a significantly negative correlation with CD10 expression (r = -0.597, P = 0.000), but no correlation with bcl-6 and bcl-2 expression.

CONCLUSIONSMUM-1/IRF4 expression is significantly higher in high-grade follicular lymphoma, indicating that these cases have a high proliferative activity, more aggressive behavior and poorer prognosis. MUM-1/IRF4, when strongly expressed, is another helpful marker for the diagnosis of high-grade follicular lymphoma.
