It is estimated that over 35% of tumors are diagnosed at locally advanced disease, stage ⅠB2-ⅡB with an estimated 5-year overall survival of 60%. During the last decades, the initial treatment for these women has been debated and largely varies through different countries. Thus, radical concurrent chemoradiation is the standard of care in United Sated and Canada, and neoadjuvant chemotherapy followed by radical surgery is the first line of treatment in some institutions of Europe, Asia and Latin America. Until today, there is no evidence of which strategy is better over the other. This article describe the evidence as well as the advantages and disadvantages of the main strategies of treatment for women affected by uterine cervical cancer stage ⅠB2-ⅡB.展开更多

Methods： With case control design adopted, patients with the CHD （40 of BS, 37 of non-BS） and 39 healthy subjects for control, all fitting to the inclusion criteria, were selected in this study. The number of affected coronary branches was recorded by the contrast examination. The mean fluorescence intensity （MFI） of GPⅠb, GPⅡb-Ⅲa, and GMP-140 （CD42b, CD61, CD62p） in patients and healthy persons was measured with flow cytometry, the polymorphism of HPA-3 gene was detected by Taqman probe technique and that of HPA-2 gene was determined by gene sequencing. Results： MFI of CD61 and CD62p was higher in the CHD patients than in the healthy control, which was also higher in patients of BS syndrome than in patients of non-BS syndrome （P〈0.05）; MFI of CD42b was lower in the CHD patients than in the healthy control （P〈0.05）, but showing insignificant difference between BS and non-BS syndrome （P〉0.05）; at the same time, no significant difference of all the above-mentioned three MFI could be found in patients with various numbers of affected coronary branches, neither in patients with different genotypes at GPⅡb HPA-3 and GPⅠb HPA-2 polymorphism loci （P〉0.05）. Conclusion： （1） The activities of GP Ⅱ b-Ⅲa and GMP-140 were obviously increased in the genesis and developing process of CHD and CHD of BS syndrome, and so they could be taken as one of the objective indexes for microscopic diagnosis of BS syndrome. （2） The level of GPⅠb was lower in CHD patients than in healthy persons, but it was not a sensitive indicator for BS syndrome of CHD. （3） Levels of GP Ⅱb-Ⅲa, GPⅠb and GMP-140 were not related with the number of affected coronary branches in CHD patients. （4） The changes in amino-acids expression induced by the two loci brought no significant influence on GPⅠb and GP Ⅱb-Ⅲa activities.展开更多
