Background An effective purging technique plays an important role in autologous hematopoietic stem cells transplantation Photodynamic therapy (PDT) provides a novel approach for this purpose This study dealt with the purging effects of disulfodiphthalimidomethyl phthalolcyanine zinc (ZnPcS2P2)based photodynamic therapy (ZnPcPDT) Methods Fluorescence intensity of cell extracts was measured using a fluoresence spectrophotometry The proliferative potency of K562 cells and HL60 cells was detected using MTT colorimetric assay, Typan blue dye exclusion method, colony formation test The proliferative potency of normal hematopoietic cells was evaluated using mixture colonyforming unit (CFUMix), granulocytemacrophage colonyforming unit (CFUGM), and erythrocyte colonyforming unit (CFUE) assays K562 cells were mixed with normal mononuclear cells (MNCs) at ratios of 1∶100 and 1∶1000 for creating the model of simulated remission bone marrow Colony formation test and nestedRTPCR were carried out to detect the residual K562 cells in cell mixture Results After a 5hour incubation with ZnPcS2P2, the content of ZnPcS2P2 in normal MNCs was the lowest value At the same time, the content in K562 cells and HL60 cells was very high Therefore, the time point was selected as the optimal one for irradiating the cell suspensions ZnPcPDT could significantly kill proliferative K562 cells and HL60 cells in a dosedependent manner At the concentration of 10 μg/ml, the inhibitory rate of ZnPcPDT on the colony formation was 100% for K562 cells, 897% for HL60 cells 025 μg/ml ZnPcPDT could completely photoinactivate residual K562 cells in the simulated remission bone marrow Under an identical condition, the inhibitory rates of CFUMix, CFUGM, CFUE were 180%, 186%, and 178% respectively Conclusion ZnPcPDT appears to be a promising approach for bone marrow purging

Porphyry copper deposits（PCDs） supply the majority of the world's copper（Cu） as well as significant amounts of molybdenum（Mo） and gold（Au）. The formation of these deposits is controlled by a variety of geological factors, among which the magmatic oxidation is one of the focuses of current research. This study investigates the redox characteristics of arc magmas by analyzing the ratio of vanadium（V） to scandium（Sc） and its correlation with the oxygen fugacity （fO2） of magmas from arcs of various crustal thicknesses globally. We compiled an extensive dataset of published V/Sc values and studied the partition coefficients of Vand Sc between minerals and silicate melts across various magmatic environments. The results demonstrate that fractional crystallization of magnetite markedly reduces V/Sc values of the residual melt. Furthermore, magnesium number（Mg#） at the onset of magnetite fractionation is strongly positively correlated with fO2of the equilibrium magma. Based on this,the oxidation of arc magmas from different crustal thicknesses can be evaluated. The result suggests that magmas generated in crusts thicker than 20 km tend to be more oxidized with increasing crust thickness. This trend is attributed to enhanced intracrustal differentiation processes involving garnet and amphibole, particularly in mature island and continental arcs. In contrast,magmas in thinner arc crusts（<20 km）, which are significantly influenced by subducted slab materials, display higher oxidation states than most of their thicker crust counterparts. These findings suggest that both subduction dynamics and crustal thickness play a vital role in determining the oxidation state of arc magmas and, consequently, their capacity to generate PCDs. Highly oxidized, primitive arc magmas are less favorable for PCD formation due to that they tend to experience magnetite fractionation and thus sulfide saturation in the early stage of magma evolution, a process leading to copper depletion.

Background Because no large prospective studies are available, this study evaluated the clinical outcomes of two drug eluting stents in bifurcation lesions. Methods Lesions with diameter of side branch ≥2.5 mm were selected. From October 2003 to June 2005, 112 patients with 113 bifurcation lesions were treated by two drug eluting stents （DESs）, technique. The location of bifurcation lesions were left anterior descending coronary artery/diagonal in 62 patients, left main distal bifurcation in 32, left circumflex coronary artery/obtute marginal branch in 18 and right coronary artery distal bifurcation in 1. Procedures for bifurcation lesions were crush or modified crush technique in 64, ＂T＂ stenting technique in 27, modified ＂Y＂ stenting, kiss stenting, ＂V＂ stenting as well as culotte stenting technique in 11, 5, 3 and 3, respectively. Among 226 lesions, 91 Cypher or Cypher select stents, 74 TAXUS and 67 Firebird were used. Final kiss balloon dilation was performed in 60 （93.7%） with crush technique after stenting. Results Success rate of percutaneous coronary intervention for the bifurcation lesions was 100%. One patient, who developed inhospital acute myocardial infarction due to subacute thrombosis, was successfully treated by a second intervention. Major adverse cardiac events rate in-hospital was 0.89% （1/112） and during followup was 7.14% （8/112）, No death occurred during the followup of all patients. Angiographic followup was effected for 46 patients, restenosis for eight, coronary artery bypass grafting for 1 and a repeat intervention for 5. Restenosis involving TAXUS, Cypher and Firebird was 5 （5/18, 27.8%）, 2 （2/17, 11.8%） and 1 （1/11, 9.1%）, respectively （P〉0.05）. Total restenotic rate was 17.4% （8/46）. Conclusions When ostium of side branch has severe stenosis and 〉12.5 mm in diameter, two-stent strategy in this bifurcation lesion is safe and effective, and the outcomes are satisfactory. Restenotic rates were not different between TAXUS, Cypher and F

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.
