We describe a newborn infant who was born wi.h.a purpuric rash and subcutaneous nodules. Skin biopsies demonstrated acute myeloid leukemia. Cytogenetic studies revealed an 11q23 rearrangement. initial bone marrow and cerebrospinal fluid examination did not demonstrate medullary or meningeal disease. Chemotherapy was initiated on the basis of the abnormal cytogenetic findings in the skin biopsy. intensive chemotherapy was, given but the infant s leukemia progressed. The patient died of refractory leukemia and secondary fungal disease. This case report supports the observation that leukemia cutis wi.h.an 11q23 rearrangement should be treated aggressively.

Exclusive responsiveness to ultraviolet li.h. (~3.2 eV) and hi.h.photogenerated charge recombination rate are the two primary drawbacks of pure TiO_(2). We combined N-doped graphene quantum dots (N-GQDs), morphology regulation, and heterojunction construction strategies to synthesize N-GQD/N-doped TiO_(2)/P-doped porous hollow g-C_(3)N_(4) nanotube (PCN) composite photocatalysts (denoted as G-TPCN). The optimal sample (G-TPCN doped wi.h.0.1wt% N-GQD, denoted as 0.1% G-TPCN) exhibits significantly enhanced photoabsorption, whi.h.is attributed to the change in bandgap caused by elemental doping (P and N), the improved li.h.-harvesting resulting from the tube structure, and the upconversion effect of N-GQDs. in addition, the internal charge separation and transfer capability of0.1% G-TPCN are dramatically boosted, and its carrier concentration is 3.7, 2.3, and 1.9 times that of N-TiO_(2), PCN, and N-TiO_(2)/PCN(TPCN-1), respectively. This phenomenon is attributed to the formation of Z-scheme heterojunction between N-TiO_(2) and PCNs, the excellent electron conduction ability of N-GQDs, and the short transfer distance caused by the porous nanotube structure. Compared wi.h.those of N-TiO_(2), PCNs, and TPCN-1, the h2 production activity of 0.1%G-TPCN under visible li.h. is enhanced by 12.4, 2.3, and 1.4times, respectively, and its ciprofloxacin (CiP) degradation rate is increased by 7.9, 5.7, and 2.9 times, respectively. The optimized performance benefits from excellent photoresponsiveness and improved carrier separation and migration efficiencies. Finally, the photocatalytic mechanism of 0.1% G-TPCN and five possible degradation pathways of CiP are proposed. This study clarifies the mechanism of multiple modification strategies to synergistically improve the photocatalytic performance of 0.1% G-TPCN and provides a potential strategy for rationally designing novel photocatalysts for environmental remediation and solar energy conversion.
