Abstract
INTRODUCTION In comparison with mononuclear leucocyte (MNL)-predominant malignant pleural effusions (MPEs), polymorphonuclear leucocyte (PMNL)-predominant MPEs have rarely been investigated and may be associated with a poorer prognosis. OBJECTIVES To investigate the characteristics and survival impact of PMNL-predominant MPEs secondary to lung cancer. METHODS This retrospective study included patients with MPE secondary to lung cancer, which were classified into the PMNL- and MNL-predominant groups according to cellular predominance in the pleural fluid. Clinical, hematological, radiological, and pleural fluid data were compared between the groups, and the survival impact of PMNL predominance in MPE was evaluated. RESULTS Of the 193 MPEs included, 37 (19%) were characterised by PMNL predominance. Compared to the MNL-predominant group, the PMNL-predominant group showed significantly poorer patient performances (P = .001), higher white blood cell counts (P = .009), higher neutrophil counts, higher blood neutrophil-to-lymphocyte ratio (P = .046), higher serum C-reactive protein (P = .003), lower serum albumin (P < .001), lower pleural fluid pH (P = .002) and higher pleural fluid lactate dehydrogenase (P = .029) levels. In contrast, most clinical and radiological findings, including the duration of symptoms, showed no significant intergroup differences. A shift towards MNL predominance was observed in only 38% of the PMNL-predominant patients who underwent repeat thoracentesis. Overall survival of the PMNL-predominant group was significantly shorter than the MNL-predominant group (P = .003). CONCLUSIONS PMNL predominance in MPEs secondary to lung cancer may be observed in variable phases with respect to the duration of symptoms and the time of thoracentesis. Overall, PMNL-predominant MPEs were associated with more advanced stages and poorer survival outcomes, compared to MNL-predominant MPEs.

Abstract
Kidney is one of the most difficult organs for regeneration. Several attempts have been performed to regenerate renal tissue using stem cells, the results were not satisfactory. Urine is major product of kidney and contains cells from renal components. Moreover, urine-derived stem cells (USCs) can be easily obtained without any health risks throughout a patient's entire life. Here, we evaluated the utility of USCs for renal tissue regeneration. In this study, the ability of USCs to differentiate into renal lineage cells was compared with that of adipose tissue-derived stem cells (ADSCs) and amniotic fluid-derived stem cells (AFSCs), with respect to surface antigen expression, morphology, immunocytochemistry, renal lineage gene expression, secreted factors, immunomodulatory marker expression, in vivo safety, and renal differentiation potency. Undifferentiated USCs were positive for CD44 and CD73, negative for CD34 and CD45, and formed aggregates after 3 weeks of renal differentiation. Undifferentiated USCs showed high SSEA4 expression, while renal-differentiated cells expressed PAX2, WT1, and CADHERIN 6. In the stem/renal lineage-associated gene analysis, OCT4, SSEA4, and CD117 were significantly downregulated over time, while PAX2, LIM1, PDGFRA, E-CADHERIN, CD24, ACTB, AQP1, OCLN, and NPHS1 were gradually upregulated. In the in vivo safety evaluation, renal-differentiated USCs did not show abnormal histology. These findings demonstrated that USCs have a similar MSC potency, renal lineage-differentiation ability, immunomodulatory effects, and in vivo safety as ADSCs and AFSCs, and showed higher levels of growth factor secretion for paracrine effects. Therefore, urine and USCs can be one of good cell sources for kidney regeneration.
