Objective To explore the prophylactic effect of T cell vaccination (TCV) on type 1 diabetes. Methods 6-week-old nondiabetic femele NOD mice were vaccinated intraperitoneally with the attenuated, activated T lymphocytes isolated from the spleen of 4-week-old nondiabetic NOD mice, 18-week-old newly diabetic NOD mice and 32-week-old long-term diabetic NOD mice. The incidence of cyclophosphamide-treated diabetes, inflammatory score of insulitis in NOD mice as well as T lymphocyte subset changes in spleen and thymus were determined after TCV. Results TCV was able to reduce the incidence of cyclophosphamide-treated diabetes, to alleviate insulitis, to increase the percentage of CD8+ T lymphocyte subset in spleen and CD4- CD8+ simple-positive T lymphocyte in thymus, and to decrease the percentage of IL-2R+ T lymphocyte and CD4+/CD8+ rate in spleen. Conclusion TCV may decrease host autoimmunity, which seems related to the changes of T lymphocyte subsets in spleen and thymus and prophylactic effect on diabetes.

Purpose To explore the expressional differences of immunohistochemical indicators between the non-mass-like and mass-like breast cancers,and to identify the biological characteristics of non-mass-like breast cancer.Material and Methods Various immunohistochemical indicators (HER2,ER,PR,Ki-67) were analyzed in 19 cases non-mass-like cancer and 18 cases mass-like breast cancer retrospectively,and the expressional differences of the two groups were compared.Results 12 cases (63.2%) were diagnosed DCIS in the non-mass-like breast cancer group,but in the mass-like breast cancer group,the majority (12 cases,66.7%) were invasive cancer.HER2,ER,PR expression had no statistical difference between the two types (P>0.05).But the Ki-67 positive rate expressed in non-mass-like breast cancer was lower significantly (P<0.05).Conclusion The HE immunohistochemical characteristics of non-mass-like breast cancer are overlapped with that of mass-like breast cancer,but Ki-67 expression has significant difference between the two groups.There are some differences in biological characteristics of these two kinds of breast cancers.

Objective:To investigate the cytokine profile expressed by CIK cells.Methods:CIK cells were induced from peripheral blood mononuclear cells in the presence of IFN-?,IL-1?,IL-2 and mAb against CD3. The phenotype and characterization of CIK cells were identified by flow cytometric analysis.Cytokine expression profiles were determined at mRNA level by semi-quantitative RT-PCR.Results:The percentage of CD3~+CD56~+ positive cells reached up to or higher than 50%.CIK cells couldn't express IFN-?、IFN-? and IFN-? under this kind of condition. But they could express IFNs principally on day 10 to 20. The level of ILs went down after steadily expressed on day 6 to 10(or 20).TNF-? and TRAIL constitutively expressed during the culture period in vitro. TNF-? maintained high expression on day 20.TGF-?_1 mainly expressed on day 30.Conclusion:CIK cells can widely express various kinds of cytokines in vitro.

Objective To construct the angiotensinogen (AGT)-targeting RNA interfering plasmids, and to explore the effect of AGT gene on the differentiation of preadipocytes 3T3-L1 in the mice.Methods The small hairpin RNA (AGT-shRNA)interference plasmids,with a scrambled Non-shRNA as control,were constructed on the basis of the activity of U6 promoter-driven expression vector psiRNA-U6.1/Neo and transfected into the mouse preadipocytes 3T3-L1.Two cell lines were generated from stable transfections.RT-PCR and SDS-PAGE were performed to monitor the mRNA and protein expressions of AGT gene,respectively.The effect of adipose AGT on the differentiation of 3T3-L1 was investigated through microscopic observation and profiling of adipocyte differentiation markers. Results Both AGT-shRNA and Non-shRNA interference vectors were successfully constructed;the expression of AGT mRNA was inhibited (P < 0.05 ) and the expression of AGT protein was 43.86% of control.Both adipocyte differentiation markers,intracytoplasmic lipid levels and glycerol-3-phophate dehydrogenase (GPDH)activities were increased during the differentiation of preadipocytes 3T3-L1,but the data were lower than those in control group (P <0.05).Conclusion AGT gene silencing can significantly inhibit the differentiation of preadipocytes 3T3-L1,which demonstrates that there is important relationship between adipocyte metabolism and renin-angiotensin system (RAS)in adipose tissue.

Objective To detect the expression and function of ZNRF3 in different kinds of thyroid cancer tissues and cells.Methods Immunohistochemistry was used to detect the expressions of ZNRF3 protein in 35 cases of papillary thyroid carcinoma and 10 cases of poorly differentiated thyroid carcinoma.The expressions of ZNRF3 gene in TPC-1 and 8505C were detected by RT-PCR,and the cell lines were derived from papillary thyroid carcinoma and poorly differentiated thyroid carcinoma respectively.After silenced ZNRF3 gene expression with lentivirus,the proliferation ability of TPC-1 cells were detected with CCK-8,the invasion and metastasis ability of TPC-1 cells were detected with Transwell.Results According to results of immunohistochemistry and RT-PCR,the expressions of ZNRF3 in papillary thyroid carcinoma cells and tissues were higher than those in poorly differentiated thyroid carcinoma cells and tissues,the differences were statistically significant (4.83±0.44 vs.3.13 ±0.59,t =2.20,P <0.05;1.01±0.06 vs.0.21±0.04,t =11.80,P<0.01).After ZNRF3 geng silencing,according to the results of CCK8,the proliferation ability of TPC-1 cells was significantly enhanced in 72 h,the difference was statistically significant (0.96 ± 0.10 vs.0.64 ± 0.05,t =3.19,P < 0.05);and according to the results of Transwell,the TPC-1 cell's invasion (0.12 ± 0.01 vs.0.09 ±0.00,t =5.48,P<0.01) and migration (0.22 ±-0.01 vs.0.17 ±0.01,t =4.58,P <0.05) also increased,the differences were statistically significant.Conclusion The expression of ZNRF3 in papillary thyroid carcinoma is higher than that in poorly differentiated thyroid cancer.ZNRF3 is tumor suppressor gene in the thyroid tumors.

Objective To evaluate the value of supersonic shear wave elastrography(SWE) in the diagnosis of benign and malignant breast lesions.Methods SWE was performed on 134 breast lesions of 123 female patients and 74 normal breast glands to determine the values of overall elastic modulus and dispersion,and ROC curves were used to assess the diagnosis boundary value of two kinds of data respectively.Results According to the diagnostic gold standard-histopathology,the values of overall elastic modulus and dispersion were statistically significant when comparing benign lesions and malignant lesions with normal glands.ROC curve displayed that,when the Youden index reached to maximum,the diagnosis boundary value of overall elastic modulus was 41.01 kPa,the sensitivity and specificity of the value were 68.5% and 83.8% respectively; the diagnosis boundary value of dispersion was 12.25 kPa,the sensitivity and specificity of the value were 87.0% and 88.7% respectively.Conclusions The values of overall elastic modulus and dispersion for solid breast lesions can be used to reflect the elastic characteristics of lesions quantificationally,which is useful to diagnose benign and malignant breast lesions in clinical.
