Despite the unusual presentation, the team was able to make a diagnosis of SLE using a combination of an atypical clinical picture, with initial signs and symptoms of weight loss, anemia, leucopenia and arthlagia, in combination with investigation results, including a positive test for anti-dsDNA antibodies. A more indolent disease course, combined with non-specific initial manifestations and low prevalence within the elderly population, often leads to delayed diagnosis. This case underscores the importance of considering SLE in the differential diagnosis of elderly patients, even in those who do not fit the typical epidemiological profile.展开更多
A novel 1,4,5-trisubstituted 1,2,3-triazole（C18H21N3O3） was synthesized by a one-pot three component reaction of 1-azidocyclohexane, 1-copper（I） phenylethyne and ethoxalyl chloride at room temperature.

The molecular structure was determined by single-crystal X-ray analysis. The compound crystallizes in the monoclinic system, space group P21/n with a = 12.8167（9）, b = 8.0966（6）, c = 16.7079（9） A, β = 98.716（2）°, Z = 4 and V = 1713.8（2）. In the crystal, the molecules are related by inversion and paired into dimers via C–H…O and C–O…C interactions involving（oxo） acetate groups. Furthermore, X-ray analysis results are compared with the optimized structure computed by using B3 LYP method with 6-311 G basis set. The calculated results showed that optimized geometry can well reproduce the crystal structure parameters. The bioassay results indicate that the compound has good antibacterial and antifungal activities.展开更多
