Objective To investigate the clinical features of polypoidal choroidal vasculopathy. Methods The clinical manifestations and the findings of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) of 7 eyes in 6 patients with polypoidal choroidal vasculopathy were analyzed retrospectively. Results The ophthalmoscopic examination of PCV in this series of patients revealed orange-red lesions mainly in macular region in early stage, and then hemorrhage, exudation, edema, serous and (or) hemorrhagic detachment of retinal pigment epithelium in affected portions in advanced stage, and retinal and choroidal atrophy in late stage. FFA discovered the vascular dilation at the border of the choroidal vascular network in 1 eye, dotted hyperfluorescence in 6 eyes, and patches of hyperfluorescence in late phase. ICGA disclosed a vascular branching network in choroid with polypoid pattern of the terminal path of the vessels of network in early phase in 5 eyes, and the typical dotted or clustered polypoidal hyperfluorescence in 7 eyes in late phase. Conclusion The characteristic findings of FFA and ICGA are very diagnostic for PCV.

OBJECTIVE: To explore the effects of Liangxue Huayu therapy (LXHYT), a traditional Chinese herbal therapy for cooling blood and dissipating blood stasis, on rat model of experimental autoimmune thyroiditis (EAT) and its impact on tumor necrosis factor-alpha and interleukin-10 mRNA expressions in peripheral blood mononuclear cells. METHODS: Forty Wistar rats were randomly divided into five groups: normal control group, untreated EAT group, cyclosporine A (CyA)-treated group, Tripterygium glycosides-treated group and Liangxue Huayu Recipe (LXHYR)-treated group. The interventions were given by gavage to the rats in different groups once a day. All rats were sacrificed after 4-week treatment, and the level of serum thyroglobulin antibodies (TgAb) and the changes of histological grade of thyroid specimen were assessed by blind evaluation. Expressions of tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) mRNAs in peripheral blood mononuclear cells were assessed by real-time reverse transcription polymerase chain reaction method. RESULTS: There was a significant increase in the serum TgAb level and severe inflammatory infiltration in the untreated group. Expression of TNF-alpha mRNA in peripheral blood mononuclear cells was increased, while the expression of IL-10 mRNA was decreased in the untreated group (P<0.01). Compared with the untreated group, CyA, Tripterygium glycosides and LXHYF could decrease the serum TgAb level (P<0.05), but the three interventions showed no significant improvement in thyroid inflammation (P>0.05). TNF-alpha mRNA expression was decreased, while IL-10 mRNA expression was increased as compared with the untreated group (P<0.05). CONCLUSION: LXHYT can decrease the serum TgAb level and recover the balance of Th1/Th2. This may provide an experimental basis for further research of assessing the antipsoriatic effect of Chinese herbal drugs with a rat model of EAT as an alternative model of psoriasis in vivo.

Objective To analyze the impact of tripterygium glycosides (TG) on the expression of CXCR3 and CCR4 gene in peripheral blood mononuclear cells from experimental autoimmune thyroiditis (EAT) rats, and to explore the possible mechanism for regulation of Th1/Th2 balance by TG. Methods EAT was induced in 20 rats, which were randomly divided into two groups, i.e., control group and TG group, to receive intragastric physiological saline and TG suspension (5.5 mg/kg) daily, respectively. The rats were killed 4weeks later, and total RNA was extracted from the peripheral blood mononuclear cells of rats and used for cRNA synthesis. The gene expressions of CXCR3 and CCR4 were detected with a Th1-Th2-Th3 microarray gene chip and realtime RT-PCR. Results Compared with the control group, there was a significant decrease in the mRNA expression of CXCR3 (0.52 ± 0.10 vs. 1.05 ± 0.17, P < 0.01 ) and CXCR3/CCR4 ratio (0.39 ± 0.22 vs. 1.04 ± 0.12, P< 0.01) in the TG group, together with an increase in the mRNA expression of CCR4 (1.56 ±0.13 vs. 1.02 ± 0.09, P < 0.01 ). Conclusions TG could regulate the number of Th1 and Th2 cells as well as their cytokine expression ratio likely by reducing CXCR3 and enhancing CCR4 expression, so as to modulate the Th1/Th2 balance in EAT rats.

Objective To screen the tumor specific antigens, and explore new methods for diagnosis and therapy of tumor. Methods Hela cells, the human cervical carcinoma cell line, were used to immunize the BALB/C mice, and the positive hybridomas were screened by rosette formation screening system in human carcinoma cell line Colo205, Burkitt lymphoma cell line, Raji, etc. The immunofluorescence staining and flow cytometry analysis were performed to characterize if the prepared monoclonal antibodies (mAb) could reorganize the natural membrane antigen expressed on Hela, Colo205, Raji, PLA801, 7901, Jurkat, 293T, ECV304 and resting or activated human peripheral blood mononuclear cells (PBMC). Furthermore, the membrane protein of Hela, Raji and Sp2/0 cells was segregated by ultracentrifugation and the mAbs were cross-linked with the Sepharose CL-4B. In order to identify the molecules which could be recognized by the prepared mAbs, immunoprecipitation was performed to purify the tumor antigen candidates with the cell membrane protein from Hela, Raji and SP2/0 (as negative control) through Sepharose CL-4B cross-linked with the prepared mAbs. Finally, western blotting was performed to detect the molecular weight of the products from the immunoprecipitation. Results Three mAbs were obtained which could recognize the tumor antigen candidates expressed in several human carcinoma cell lines, such as Hela, Raji and Colo205, and some embryonic cell lines, such as 293T and ECV304, but they could not bind to Jurkat, PLA801, 7901, SP2/0, resting or activated human PBMC. Western blotting results indicated that the three mAbs could recognize a 47kD molecule which expressed in Hela and Raji but not on SP2/0 cell membrane. Conclusion Three mAbs, which can recognize tumor membrane antigen candidates, are obtained, providing useful tools for screening and identify the tumor specific antigens.
