Objective To investigate skin rash characteristics in patients with dengue fever, and to explore factors associated with the occurrence of skin rashes in dengue fever. Methods Skin rashes were observed in 127 hospitalized patients with dengue fever. Clinical and laboratory data were collected from these patients. Statistical analysis was carried out by using a two-sample t-test and chi-square test with the SPSS16.0 software. Results Out of the 127 inpatients, 88 (69.29%)had skin rashes, which usually developed within 5-7 (average, 5.06 ± 2.50)days after fever onset. Among the 88 patients, 37(42.05%)developed skin rashes during fever, while 51(57.95%)after the drop of body temperature. Moreover, 48 (54.55%) patients complained of itching, while 39 (44.32%) never felt itch, and 1 complained of a tingling sensation all over the body. The type of skin rashes was various. Congestive erythema and macules were observed on both palms in 26 (29.55%)patients, and might be the characteristic skin presentation of dengue fever. Skin rashes usually began in both lower extremities, whereas the order of their subsidence was unclear. There was a significant difference in blood platelet (PLT) count as well as alanine transaminase and aspartate transaminase levels between patients with skin rashes and those without(all P=0.00). However, no significant difference was observed in the count of leukocytes, neutrophils or PLT, or the levels of alanine transaminase or aspartate transaminase between patients with hemorrhagic rashes and those with nonhemorrhagic rashes or between patients with itching and those without (all P>0.05). Conclusions Dengue fever has various skin rashes, and congestive erythema and macules on both palms may be the distinctive presentation of dengue fever.

Objective To measure the parameters of mitral valve leaflets and mitral annulus in patientswithmildmitralregurgitation( MR )byreal timethree-dimensionaltransesophagealechocardiography (RT-3D-TEE),and explored the mechanism of MR.MethodsFifty-seven MR subjects were selected and twenty-eight subjects without mitral regurgitation were served as control group,all subjects were examined by RT-3D-TEE and acquired image,mitral valve quantification (MVQ) software was used for post-processing.Mitral annulus parameters (H/DAIPm,E2D,θAv-Mv,mitral annulus θnpa) and mitral valve leaflets parameters(A3DE,L2DAIPm,VA1-3tentVp1-3tentVtentHtentθnpa ) at the end of systolic were measured.The results of two groups were compared,and the most affected parameters to mild mitralregurgitation were selected.Results Compared with control group,VA3tent was decreased,mitral annulus θnpa and L2DAIPm increased,and the mitral valve leaflets θnpa was independently correlation factor of mild mitral regurgitation.ConclusionsThe mitral annulus geometry to flat in subjects with mild MR,the mitral valve local area is increased in subjects with mild MR,the mitral valve leaflets θnpa is independently correlation factor of mild mitral regurgitation.

Objective To establish an immature rabbit model of avascular necrosis of the femoral head in-duced by exercise. Methods Ten male, immature New Zealand white rabbits were subjected to large range, in- tense passive movement and concentric impingement on their right hips for 4 weeks. The left hips were used as self-controls. Then X-ray and magnetic resonance imaging, gross anatomical observation and histological examination were used to evaluate avascular necrosis of the femoral head. Result After 4 weeks, avascular necrosis of the femoral head was successfully replicated. Increased bone density, decreased osteoepiphysis height and indistinct bone trabec-ula were found in X-rays of the right hips. In MRI images obvious joint hydrops could be detected in all right hips, and schistic low signal areas in the femoral head could be seen in TIWI and T2WI images. Thin bone trabeculae of low density, with irregular and broken structures, were also found in H-E sections. Conclusion An immature rab-bit model of avascular necrosis of femoral head can be successfully induced through large range, intense, passive movement and concentric impingement.
