Modernized study on eye's signs of blood-stasis syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To make out a computerized formula to diagnose eye's signs of blood-stasis syndrome (BSS), and to improve the previous diagnostic methods by naked eyes.</p><p><b>METHODS</b>The formula was created by detecting and analyzing the changes of eye's signs in 544 patients (261 of non-BSS and 283 of BSS) quantitatively, adopting computer's color scale principle. And the sensitivity, specificity and accuracy of the formula were verified in 382 patients (97 non-BSS and 285 of BSS). The computerized integral was compared with the naked eye integral, and the normal reference value was calculated with percentile.</p><p><b>RESULTS</b>Various observatory indices of eye's sign were positively correlated with BSS. The specificity of the computerized method was 83.5%, and the diagnostic sensitivity was 89.8%, the accuracy 88.2%, and the correct index 0.733. Comparisons between the computerized integral method and the naked eye integral method showed significant difference in patients of non-BSS or of BSS in various degrees (including mild, moderate and severe) (P < 0.01). The reference value of the naked eye method was below 15.</p><p><b>CONCLUSION</b>The computerized formula of eye's signs has higher specificity and sensitivity in the diagnosis of BSS, while the naked eye integral method is proved to be useful.</p>

Screening indices for diagnosis of traditional blood stasis syndrome by Delphi method / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To screening out the indices for diagnosis of traditional blood stasis syndrome (BSS) by investigating experts'experiences, evaluating their significance, for providing reference to the quantitative diagnosis of BSS.</p><p><b>METHODS</b>Using Delphi method, some diagnostic indices that being considered as importance by experts was screened out, and applied in 108 patients to assess their specificity and sensitivity in double-blinded condition, taking the Chinese diagnostic standard as gold standard.</p><p><b>RESULTS</b>Ten indices were screened out from 50 items for traditional observing on BSS, which are considered essential by experts uniform, and showed a coincidence rate of 91.4% when applied for comprehensive diagnosis of BSS.</p><p><b>CONCLUSION</b>The indices for BSS diagnosis screened out by Delphi method can serve as a reference to the BSS quantitative diagnosis.</p>
