Objective To study the clinical, laboratory, X-ray and the pathological features of Parkinson disease patients with rheumatoid-like deformities. Methods One patient was described and the relevant English literature in recent 50 years were reviewed. Results Rheumatoid-like deformities in Parkinson disease was mostly observed in women. The ratio between male and female was about 1:5.6. Joint deformities occurred after 7.6 years of Parkinson's disease in average. The manifestations of joints included the flexion of the metacarpophalangeal (MCP) joints, hyperextension of the proximal interphalangeal (PIP) joints, flexion of the distal interphalangeal (DIP) joints, and ulnar deviation of wrists and bilateral feet hallux valgus. Whole-blood analysis, biochemistry profile, erythrocyte sedimentation rate, C -reactive protein were all in normal range. Rheumatoid factor and ANA, anti-ENA profile, AKA, anti-cyclic citrullinated peptide (anti-CCP) antibody and antiperinuclear factor (APF) were all negative. Periarticular erosion was not observed in plaint X -ray films. Synovial pathology showed non -specific infla -mmation without classical syno vial membrane proliferation and pannus formation. NSAIDs and DMARDs were uneffective, but on the contrary, anti -parkinson' s disease therapy could relieve joints symptoms. Conclusion Parkinson disease can be accompanied with rheumatoid-like deformities which may be misdiagnosed as RA and should be differentiated from RA by laboratory, radiographs and synovium pathology examination.

Background Eicosapentaenoic acid(EPA)function as the critical lipid mediators involved in several biological events in human body and play important role in suppressing the genesis of vascular endothelial growth factor (VEGF),migration and proliferation of vascular endothelial cells.Many ocular diseases were proved to be associated with neovascularization.Objecfive The purpose of this study was to investigate the inhibitory effect of EPA on the proliferation of human umbilical vein endothelial cells (HUVEC) indueed by VEGF. Methods HUVEC strain was cultured and passaged,and difierent concentrations of EPA were added to the medium with and without VEGF.The cultured cells were identified by antiofactor Ⅷ polyclonal antibody.The suppressing role of different concentrations of EPA on the proliferation of VEGF-induced or-uninduced HUVEC was assessed by MTT method.The influence of difierent concentrations of EPA on the cellular cycle of VEGF-induced HUVEC was assayed using flow eytometry.The expression of Flk-1,a receptor of VEGF,in the HUVEC Was detected by immunohistochemistry. Results Cultured HUVEC showed the ftlsiform in shape and presented with the cobblestone-like arrangement with the positive response for Ⅷ factor-related antigen.Various concentrations of EPA showed obviously inhibitory effect on VEGF-induced or-unindueed HUVEC at a dose-dependent manner (F=23.072.P=0.000).The inhibitory ability of EPA on VEGF-induced HUVEC was stronger than VEGF-uninduced HUVEC(F=41.417,P=0.000).In 24,48 and 72 hours,the action of EPA on the proliferation of HUVEC was gradually enhanced with the prolong of time(F=1.495,P=0.236).Cell cycle analysis indicated that EPA arrested VEGF-induced HUVEC in G0/G1 phase.The ratio of HUVEC in G0/G1 phase in EPA group was(75.83±1.56)%,and that in control groups was(68.62±1.44)%,showing a significant difference between them(t=-5.88,P=0.00),and no apoptosis of HUVEC was found in both groups.Flk-1 was strongly expressed in the cellular nucleus and cytoplasm in control group.However,the positive expressing intensity of Flk-1 in the HUVEC weakened,and the positive cell number was evidently less in EPA group. Conclusion EPA can inhibit the proliferation of VEGF induced HUVEC through arresting the synthesis of DNA of HUVEC and downregulate the expression of Flk-1 in HUVEC.These results suggest that EPA might exert an antiangiogenic effect.

Objective To investigate the value of Periodically Rotated Overlapping Parallel Lines Enhanced Reconstruction (PROPELLER) in omitting the motion and susceptibility artifacts in head MRI. Methods Thirty nine cases of restless patients and eighteen cases with fixed metal artificial tooth underwent head MRI using T2WI or DWI with PROPELLER during April and Nov. in 2006 were analyzed respectively. The PROPELLER images and common MRI images were compared. Results The common images of 39 restless patients were not suitable to diagnosis because of moving artifact and pure imaging quality, while the PROPELLER T2WI images eliminate the artifact obviously and display the lesion clearly. Susceptibility artifacts were found in 18 patients with artificial tooth in common MRI images, and the artifacts were almost not found in PROPELLER DWI images and so satisfied the need of diagnoses. Conclusion PROPELLER T2WI and DWI can remove significantly the motion and susceptibility artifacts, and so acquire images of high resolution, low artifacts, and high quality to satisfy the need of diagnoses.

Objective To study the effects of sample digestion conditions on measurement results of urinary iodine determined by As(Ⅲ)-Ce4+ catalytic spectrophotometry with ammonium persulfate digestion,and to promote the application of newly revised (the 2012 edition) national standard method for determination of urinary iodine.Methods According to the newly revised national standard method,various digestion conditions,such as ammonium persulfate concentration (0.8-1.3 mol/L,group interval 0.1),digestion instruments (heating block and drying oven) and standing time after digestion(0.5,1.0,2.0,4.0 and 22.0 h),were studied.The samples included 3 standard materials,which were GWB09108k,GWB09109f and GWB09110m containing iodine of (68.2 ± 9.0),(138.0 ± 10.0) and (221.0 ± 10.0) μg/L,and 5 urine samples with iodine concentration of 100-300 μg/L.Results Measurement results among the three groups of 0.9,1.0 and 1.1 mol/L ammonium persulfate digestion fluid showed no significant difference(P ＞ 0.05).The digestive effect showed no significant difference between heating block and drying oven (P ＞ 0.05) except one standard material in low concentration (GBW09108k).After digestion,samples were placed 0.5-22.0 h,the measurement results between groups showed no significant difference (P ＞ 0.05).Conclusions Appropriate concentrations of ammonium persulfate are from 0.9 mol/L to 1.1 mol/L.Heating block is recommended for the digestion,however,when absent,drying oven can be used alternatively.The standing times from 0.5 h to 22 h after digestion have not affected the measurement results.
