METHODS： A total of 42 specimens of RB undergone primary enucleation were selected for the research. Sections from the formalin-fixed, paraffin-embedded specimens were stained with HE and immunohistochemistry to detect the expression of GSTπ, P-gp and LRP.RESULTS： GSTπ was expressed in 39/42（92.86%） RBs and in 9/9（100%） well-differentiated RBs. P-gp/GSTπ was found in 30（71.42%） of 42 RBs. Totally 9（21.43%） tumors were well differentiated and 33（78.57%） were poorly differentiated. Totally 15（35.71%） eyes had optic nerve（ON） tumor invasion, 36（85.71%） had choroidal tumor invasion, and 14（33.33%） had simultaneous choroidal and ON invasion. There was no statistically significant relationship between P-gp, GSTπ, LRP positivity and the degree of ocular layer tumor invasion and ON tumor invasion（P〉0.05）. CONCLUSION： RB intrinsically expresses GSTπ, P-gp and LRP. GSTπ expression is positive in 100% welldifferentiation ones, so in which way it is correlated with differentiation. But the other two proteins expressions are not related to tumor differentiation and to the degree of tumor invasion. GSTπ may be a new target of chemotherapy in RB.展开更多

Immunohistochemical antibodies for C-myc, Ki-67, pan-cytokeratin, and vimentin were employed.RESULTS: Median age of PA was 43.2 y(from 21 to 75). The 35 patients(54.7%) were male and 29 patients(45.3%) were female. For the PAs, the average positivity of C-myc was 4.6%;the average proliferation index of Ki-67 was 3.2%;pan-cytokeratin was positive in ductal cells, and vimentin was positive in myoepithelial cells. Median age of Ca-ex-PA was 54.3 y(from 26 to 76). There were 7 male patients(46.7%) and 8 female patients(53.3%). Among 15 Ca-ex-PAs, there were 6 myoepithelial carcinomas, 4 adenocarcinomas, 3 epithelial-myoepithelial carcinomas, and 2 squamous cell carcinomas. For the Ca-ex-PAs, the average positivity of C-myc was 36.4%;the average proliferation index of Ki-67 was 29.2%;pan-cytokeratin was positive in all cases, and vimentin was positive in myoepithelial carcinomas.CONCLUSION: PA has a lower positivity of C-myc and Ki-67, while Ca-ex-PA had a higher positivity of these two biomarkers. These four biomarkers as a set could provide valuable clues in the differential diagnosis between Ca-exPA and PA. Our results indicate that the activation of C-myc could play an important role in the pathogenesis of Ca-exPA and PA.展开更多

METHODS： A total of 30 patients with TAO were recruited at Zhongshan Ophthalmic Center from May 2015 to December 2015. Peripheral blood mononuclear cells（PBMCs） were separated from blood samples of 30 TAO patients and 16 healthy controls and stimulated with CD40 ligand and CpG for 48h. The frequency of IL-10＋ B cells was examined by flow cytometry and the correlation between the frequency of IL-10＋ B cells and clinical features of TAO was analyzed by SPSS. RESULTS： The frequency of IL-10＋ B cells among CD19＋ B cells in TAO patients was significantly lower than in healthy controls（TAO： 4.66%±1.88% vs healthy control： 6.82%±2.40%, P〈0.01）. The frequency of IL-10＋ B cells showed a positive correlation with disease activity of TAO measured by Clinical Activity Score（CAS）（r=0.50, P〈0.01）, and became higher in TAO patients with family history of Graves＇ disease（GD）（P=0.04）. CONCLUSION： The decrease of the frequency of IL-10＋ B cells in TAO patients indicates the deficiency of B10 cells in TAO, and the positive association with disease activity suggests its important role in TAO inflammation regulation.展开更多

Methods A total of 452 patients with common HFMD were randomly assigned to receive Western medicine alone (n=220) or combined with TCM (Reduning or Xiyanping injections) (n=232). The primary outcome was the incidence rate of rash/herpes disappearance within 5 days, while secondary outcomes included the incidence rate for fever, cough, lethargy, agitation, and vomiting clearance within 5 days. Results The rash/herpes disappearance rate was 45.5% (100/220) in Western medicine therapy group, and 67.2% (156/232) in TCM and Western medicine combined therapy group, with significant difference (P<0.001). Moreover, TCM remarkably increased the incidence rate of secondary disappearance, which was 56.4%in Western medicine therapy group and 71.4%in TCM and Western medicine combined therapy group (P=0.001). No drug-related adverse events were observed. Conclusions It’s suggested that the integrative TCM and Western medicine therapy achieved a better therapeutic efficacy. TCM may become an important complementary therapy on relieving the symptoms of HFMD.展开更多
