? AlM: To examine choroidal thickness and its relationship with axial length and spherical equivalent by spectral domain optical coherence tomography ( SD -OCT ) in patients with myopic choroidal neovascularization ( mCNV) .
?METHODS: We prospectively recruited 30 cases of mCNV in Beijing Anzhen Hospital from October 2010 to December 2014. SD-OCT was used to measure choroidal thickness subfoveally and at 1. 5mm superiorly, inferiorly, nasally and temporally ( SFCT, SCT1. 5mm , lCT1. 5mm , NCT1. 5mm , TCT1. 5mm ) . Paired t- test was conducted to assess the difference of spherical equivalent, axial length and choroidal thickness between mCNV group and controls. Logistic regression analysis was performed to evaluate the correlation between spherical equivalent, axial length, choroidal thickness and mCNV.
?RESULTS: The difference of spherical equivalent and axial length between mCNV group and controls was not significant (P>0. 05). lnferior was decreased in mCNV group compared with controls (140. 85±33. 46μm vs 168. 95±45. 36μm). The difference was significant (P=0. 008). Logistic regression demonstrated that decreased choroidal thickness ( lCT1. 5mm ) at inferior location was associated with mCNV (OR=2. 12;95%CI 1. 35~3. 28;P=0. 02).
?CONCLUSlON: The decrease of lCT1. 5MM may be one of the risk factors of mCNV.

Objective To study the effects of citrullinated vimentin (cVim) on the maturation and immunologic function of dendritic cells (DCs) from rheumatoid arthritis (RA) peripheral blood.Methods In the present study,mononuclear cells were isolated from the peripheral blood of patients with RA and cultivated in media containing GM-CSF and IL-4 to generate immature DCs (imDCs).The imDCs generated were stimulated with citrullinated vimentin and vimentin.LPS was used as the positive control and PBS was used as the negative control.The expression of surface molecules on the DCs,such as CD14,CD80,CD83,CD86,MHC Ⅰ and MHC Ⅱ were analyzed with FACS.The capability of the stimulatory activity of the DCs on allogeneic T cells in mixed reaction was tested by MTS.t-test was used for statistical analysis.Results Compared to untreated DCs,DCs treated with LPS increased the expression levels of MHC Ⅱ,CD80,CD83 and CD86 (1.07±0.14,1.25±0.13,1.90±1.08,2.44±0.65,P＜0.05),while cVim increased the expression levels of MHC Ⅱ ( 1.18±0.09,P＜0.05) and CD83 ( 1.97±0.99,P＜0.01 ),and Vim decreased the expression levels of CD80 (0.82±0.18,P＜0.01 ).It was demonstrated that the expression levels of MHC Ⅱ on DCs pulsed with cVim were significantly higher than that of the DCs with LPS,but the expression levels of CD80 and CD86 were not significantly different.The expression levels of MHC Ⅱ and CD83 on DCs pulsed with cVim were significantly higher than that of the DCs with Vim.The mixed lymphocyte reaction showed that the DCs induced by LPS and cVim trigerred the proli-feration of allogenic T cells obviously.Conclusion This result suggests that cVim could promote the phenotypic maturation of DCs and increase the expression of costimulatory molecules.

OBJECTIVETo investigate the semen quality of cancer patients and search for a better way of sperm cryopreservation for them.

METHODSWe retrospectively analyzed the quality of the semen from 43 cancer patients under cryopreservation in the Sperm Bank of Zhejiang Province, and compared the semen parameters between the cancer patients and 248 normal donors as well as between the testicular cancer cases (n=22) and non-testicular cancer cases (n=21).

RESULTSThe cancer patients exhibited significantly lower semen quality than the normal donors as in sperm concentration (60.90 x 10(6)/ml vs 74.27 x 10(6)/ml), progressive motility (41.07% vs 51.79%), and recovery rate (49.98% vs 57.33%) (all P <0.05). Furthermore, the progressive sperm motility and sperm recovery rate after freezing were significantly decreased in the testicular cancer cases (15.68% and 42.81%) than in the non-testicular cancer cases (28.36% and 57.53%) (both P <0.05).

CONCLUSIONSemen quality declines in cancer patients, and therefore early sperm cryopreservation is essential for them. Due to the poor sperm motility and recovery rate of testicular cancer patients after freezing, further investigation is required on the improvement of sperm cryopreservation methods.

Mitochondrial cytochrome oxidase III (COIII) of duck was successfully amplified by PCR-mtDNA with duck muscle DNA as the template (GenBank Accession No. DQ655706). Cloning sequence analysis shows that the 784 bp nucleotides of COIII gene were contained. Through homology analysis, we confirmed that the cytochrome oxidase III (COIII) was relatively conservative. The method of PCR-mtDNA can be designed to detect the components of duck origin. And then, the method of PCR can be applied to amplify with the muscle DNA of various animal and feedstuff as the template, repeated verification, the primer (P3, P4) with strong specificity and good stability is screened, which can only amplify the sequence of duck. The special sequence contains 226 bp, the amplified product of 226 bp was sequenced and analyzed, it showed 100% homology with duck mtDNA COIII gene, which proved the accuracy of the special primer. The test that used different concentration of DNA with P3 and P4 is the sensitive experiment by PCR. The result showed that the primer has much specialty and rather sensitivity. So it is a way to detect the duck origin in the muscle of various animal and feedstuff.
