Ocular manifestations and quality of life in patients after hematopoietic stem cell transplantation

AIM:To explore the relationship between ocular and systemic conditions and the impact of ocular complications on the quality of life(QOL)in patients after allogeneic hematopoietic stem cell transplantation(ALLO-HSCT).METHODS:Forty-four patients with severe hematopoietic disease were enrolled after ALLO-HSCT at our center from July 2018 to October 2020.They completed two questionnaires:the Ocular Surface Disease Index(OSDI)and the quality-of-life scale for Chinese patients with visual impairment(SQOL-DV1).Ocular conditions and systemic conditions were also assessed.RESULTS:Eye damage was correlated with total bilirubin(P=0.005),and gamma-glutamyl transferase(GGT)(P=0.021).There was no significant correlation between the overall QOL score and OSDI(P=0.8226)or SQOLDV1(P=0.9526)scores.The OSDI and the overall QOL score were not correlated with ocular conditions,including best-corrected visual acuity(BCVA),intraocular pressure,Schirmer tear test II,sodium fluorescein staining,tear film breakup time,and tear meniscus height.SQOLDV1 was correlated with BCVA(P=0.0007),sodium fluorescein staining(P=0.007),and tear film breakup time(P=0.0146).CONCLUSION:In some patients,early ocular symptoms are not evident after ALLO-HSCT,while ocular surface complications can be observed after a comprehensive ophthalmological examination.Especially for those with elevated total bilirubin or GGT,regular ophthalmic follow-up visits are essential to diagnose and treat ocular graft versus host disease(o GVHD),especially for patients with elevated total bilirubin or GGT.

A chain-like compound of Si@CNT nanostructures and MOF-derived porous carbon as an anode for Li-ion batteries

Silicon anodes are considered to have great prospects for use in batteries;however,many of their defects still need to be improved.The preparation of hybrid materials based on porous carbon is one of the effective ways to alleviate the adverse impact resulting from the volume change and the inferior electronic conductivity of a silicon electrode.Herein,a chain-like carbon cluster structure is prepared,in which MOF-derived porous carbon acts as a shell structure to integrally encapsulate Si nanoparticles,and CNTs play a role in connecting carbon shells.Based on the exclusive structure,the carbon shell can accommodate the volume expansion more effectively,and CNTs can improve the overall stability and conductivity.The resulting composite reveals excellent rate capacity and enhanced cycling stability;in particular,a capacity of 732 mA·h·g^(-1) at 2 A·g^(-1) is achieved with a reservation rate of 72.3% after cycling 100 times at 1 A·g^(-1).

Photoluminescence in wide band gap corundum Mg4Ta2O9 single crystals

As is well known,the basic intrinsic properties of materials can be significant for their practical applications.In this work,the room-temperature absorption,transmittance,reflectance spectra,and relative photoelectricities parameters of the Mg4Ta2O9 crystals are demonstrated.Meanwhile,the polarized Raman spectra of Mg4Ta2O9 crystals are also described.The room-temperature photoluminescence(PL)and the temperature-dependent PL for Mg4Ta2O9 crystals are obtained.Significantly,we observe a phonon-participated PL process in Mg4Ta2O9.

Mechanism Exploration of the Classical Traditional Chinese Medicine Formula Huoluo Xiaoling Pill in Clinical Treatment and the Traditional Chinese Medicine Theory“Treating Different Diseases with the Same Method”:A Network Pharmacology Study and Molecula Docking Verification

Objective: To analyze the possible mechanism of the Huoluo Xiaoling Pill in the treatment of three diseases, hyperglycemia, hyperlipidemia, and metabolic syndrome, and to provide ideas for learning the mechanism of “Treating different diseases with the same method” in Traditional Chinese Medicine(TCM) theory. Materials and Methods: The Traditional Chinese Medicine System Pharmacology Database and Uni Prot databases were used to screen the main ingredients and targets of the Huoluo Xiaoling Pill. The Gene Cards database was used to screen the targets of the diseases, and Cytoscape 3.7.2 was used to construct a “Drug-Components-Targets-Disease” network to determine the core components. The STRING database was used to construct the protein-protein-interaction network, and gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomics enrichment analyses were carried out on the Metascape database. Auto Dock 1.5.6 was used for molecular docking. Results: A total of 118 active components and 208 targets were screened in the Huoluo Xiaoling Pill. Quercetin, tanshinone IIA, luteolin, and ellagic acid were potential core components of Huoluo Xiaoling Pill treating the three diseases, and interleukin 6, Tumor necrosis factor, and vascular endothelial growth factor were potential key targets. Co-occurring GO biological processes involved responses to the molecules of bacterial origin, and the AGE-RAGE signaling, fluid shear stress, and atherosclerosis pathways were the co-occurring pathways. Molecular docking revealed good docking conditions between screened targets and components. Conclusion: This study predicted the mechanism of the Huoluo Xiaoling Pill in treating the three diseases. At the same time, the co-occurring targets and pathways between the three diseases provided a material basis for the TCM theory, “Treating different diseases with the same method.”
