By using chlorpromazine as a new color reagent, spetrophotometric reactions with vanadium(V) have been studied. In the medium of 0.25 mol·L-1 of H2SO4 chlorpromazin reacts with vanadium(V) at room temperature to form a bright red complex, which exhibits a maximum absorption at 520 nm. Beer’s law is obeyed in the concentration range of 0-2μg and 2-40μg V(V)/10mL with molar absorptivities of 5. 10×103 and 1.02×104L·mol-1·cm-1, respectively

前哨淋巴结(sentinel lymph node,SLN)是指肿瘤淋巴引流区域中接受淋巴引流的第一个/站淋巴结,通过前哨淋巴结活检能准确地预测区域淋巴结转移情况,避免一部分腋淋巴结阴性的乳癌早期患者进行不必要的淋巴结清扫.目前前哨淋巴结定位活检已显示出替代传统的腋淋巴结清扫的趋势.但仍有一些问题尚未解决或统一。
