NVP DPP 728 dihydrochlorideDescription:Ki: Inhibit human DPP-IV amidolytic activity with a Ki of 11 nM [1]Inhibitors of dipeptidyl peptidase 4, also known as DPP-4 inhibitors or gliptins, are a class of oral hypoglycemics that can be used to treat diabetes mellitus type 2. NVP DPP 728 dihydrochloride is a potent and orally active inhibitor of dipeptidyl peptidase (DPP)-IV.In vitro: NVP-DPP728 was found to inhibit human DPP-IV amidolytic activity with a Ki of 11 nM, a kon value of 1.3 x 105 M-1 s-1, and a koff of 1.3 x 10-3 s-1. NVP-DPP728 inhibited DPP-IV in a manner consistent with a two-step inhibition mechanism. Taken together, these data suggest that NVP-DPP728 inhibits DPP-IV through formation of a novel, reversible, nitrile-dependent complex with transition state characteristics [1]. In vivo: Aging caused a decrease in early insulin response after an oral glucose challenge in aged Wistar or DPP-IV(+) F344 rats, but not in aged DPP-IV(-) F344 rats, compared with young control groups. Glucose tolerance after an oral glucose challenge in aged DPP-IV(-) F344 rats was better than in aged DPP-IV(+) F344 and Wistar rats associated with the preservation of the early insulin response. NVP-DPP728 improved the glucose tolerance after an oral glucose challenge by potentiating the early insulin response throughout the inhibition of plasma DPP-IV activity in aged DPP-IV(+) Wistar andF34 4 rats. In contrast, NVP-DPP728 did not affect the glucose tolerance after an oral glucose challenge in aged DPP-IV(-) F344 rats. These results indicate that treatment with NVP-DPP728 ameliorated glucose tolerance in aged rats by the direct inhibition of plasma DPP-IV activity and presumably the subsequent increase in endogenous incretin action [2]. Clinical trial: NVP-DPP728 is currently in the preclinical development and no clinical trial is ongoing.Reference:[1] Hughes TE, Mone MD, Russell ME, Weldon SC, Villhauer EB.

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
