Existing research focuses on projections of OVC numbers, interventions, outcomes and descriptions of care arrangements. A lot of information exists on their poor sexual and reproductive health (SRH) status—most of it quantitative. The purpose of this paper is to present the voice and perceptions of OVC in regards to their SRH. Methods: This was a mixed-methods qualitative study drawing from phenomenology and it used purposive sampling to recruit 129 participants. Results: OVC perceptions and priorities do not always intersect with those of professionals and this has implications for existing and planned interventions. For example some OVC think favorably about early marriages while others have mechanisms of self-protection again SRH harm although this is not usually acknowledged. Conclusions: OVC demonstrate agency;therefore positioning them at the heart of service planning and delivery is an effective strategy in increasing the uptake and impact of interventions seeking to address their sexual and reproductive health needs.展开更多
目的观察基质金属蛋白酶抑制剂(tissue inhibitor of metalloproteinase,TIMP)-1在口腔疣状癌(OVC)中的表达。方法选择15例口腔疣状癌、10例正常口腔黏膜、20例口腔鳞癌标本(高、低分化鳞癌各10例),应用免疫组化S-P法检测TIMP-1的表达...目的观察基质金属蛋白酶抑制剂(tissue inhibitor of metalloproteinase,TIMP)-1在口腔疣状癌(OVC)中的表达。方法选择15例口腔疣状癌、10例正常口腔黏膜、20例口腔鳞癌标本(高、低分化鳞癌各10例),应用免疫组化S-P法检测TIMP-1的表达和分布。结果口腔疣状癌组织中TIMP-1阳性表达率为80%(12/15),高于高分化鳞癌(60%,6/10)和低分化鳞癌(40%,4/10)(P<0.05);平均染色强度高于高、低分化鳞癌(P<0.05);口腔疣状癌、口腔高分化鳞癌、口腔低分化鳞癌组织中TIMP-1的表达均高于正常口腔黏膜组织(P<0.05)。结论OVC是一种不同于口腔鳞状细胞癌的独立类型的恶性肿瘤,TIMP-1可以抑制肿瘤的浸润与转移。展开更多
