9-amino Camptothecin is a topoisomerase I inhibitor [1][2].
DNA topoisomerases relax DNA torsional strain generated during replication, transcription, recombination, repair, and chromosome condensation. The relaxation of DNA supercoiling by topoisomerase I is enabled by a mechanism of controlled rotation around a transient DNA single-strand break. Camptothecin (CPT) is isolated from the bark of the Chinese tree Camptotheca accuminata [3].
9-amino Camptothecin, a water-soluble camptothecin analogue, is a topoisomerase I inhibitor. In human HT-29 colon adenocarcinoma, 9-amino Camptothecin (9-AC) exhibited cytotoxicity with IC50 value of 19 nM. 9-AC also induced DNA damage in whole cells and nuclei at a concenstration of 85 nM and 21 nM, respectively [1].
9-amino Camptothecin had greater activity than camptothecin against human tumour xenografts, including Lewis lung carcinoma and B16 melanoma. 9-AC had entered phase II trials. In patients with advanced solid tumours, 9-amino Camptothecin exhibited anti-tumor activity [1][2].

希望有大神赐教!谢谢!
指导意见:
毕竟阴道上皮是鳞状上皮,而输尿管,膀胱,尿道的上皮是柱状上皮,形态上是不一样的.所以您要是对您的结果出怀疑态度,首先:重新留尿,做一个复检(留尿时注意防止阴道分泌物污染);或者让值班医生分析一下是那种类型的上皮(鳞状还是柱状).所以不要担心这个结果.一般情况下污染的比较多.
病情描述(发病时间、主要症状等):
体检血常规中血小板计数343.血小板比积0.39.
尿检中白细胞计数26.2.上皮细胞计数10.30
心电图下写窦性心律,p-r间期偏短
