Prognostic value of circulating tumor cells and its association with the expression of cancer stem cells in nasopharyngeal carcinoma patients.

The release of circulating tumor cells (CTCs) into vasculature is an early event in the metastatic process and the detection of CTCs has been widely used clinically. In addition, cancer stem cells (CSCs) are the source of distant metastasis. However, the relationship between CTCs and CSCs in nasopharyngeal carcinoma (NPC) patients was largely unknown.

[Significance of serum anti-Clq Ab in evaluation of lupus nephritis activity and its curative effects of pharmacotherapy on lupus nephritis].

Objective: To investigate the significance of serum anti-C1q Ab of evaluation of lupus nephritis activity and its curative effects of cyclophophamide therapy on lupus nephritis (LN).

Methods: The level of serum anti-C1q antibody of 75 patients with LN was examined by enzyme-linked immunosorbent assay (ELISA) of the 75 patients the incipient cases had never received corticosteroid and immunosuppressant and the recurrent cases had stopped the immunosuppressant treatment for more than 3 months and were treated, if so, with prednisone with the dosage View Article and Find Full Text PDF
