Development and Validation of a Nomogram for Predicting Acute Kidney Injury in Septic Patients.

Purpose: Sepsis-associated acute kidney injury (S-AKI) is associated with increased morbidity and mortality. We aimed to develop a nomogram for predicting the risk of S-AKI patients.

Patients And Methods: We collected data from septic patients admitted to the Provincial Hospital Affiliated with Shandong First Medical University from January 2019 to September 2022.

Constructing MXene-based mixed-dimensional structure with multiple interfaces to optimize dielectric-magnetic synergistic effect for effective electromagnetic wave absorption.

Exploring efficient microwave absorbing materials (MAMs) which could convert electromagnetic (EM) energy into thermal energy represents an approbatory vision to reducing EM radiation and interference. Designing of mixed-dimensional structure with multiple interfaces represents the available target to investigate an ideal MAMs, which maximizes the superiority of mixed-dimensional structure in electromagnetic wave absorption (EMWA). Herein, we take full advantage of multiple interfaces engineering of MXene for optimizing the impedance matching to improve EMWA, MXene-based mixed-dimensional structure was designed by incorporating three-dimensional FeC@Carbon layers coated zero-dimensional FeO nanoparticles (NPs) supported two-dimensional MXene nanosheets (MXene/FeO@FeC@Carbon, MFC).

Nitrogen-Doped Nanoporous Anodic Stainless Steel Foils towards Flexible Supercapacitors.

In this work, we report the fabrication and enhanced supercapacitive performance of nitrogen-doped nanoporous stainless steel foils, which have been prepared by electrochemical anodization and subsequent thermal annealing in ammonia atmosphere. The nanoporous oxide layers are grown on type-304 stainless steel foil with optimal thickness ~11.9 μm.

One-Step Construction of Multi-Walled CNTs Loaded with Alpha-FeO Nanoparticles for Efficient Photocatalytic Properties.

The aggregation and the rapid restructuring of the photoinduced electron-hole pairs restructuring in the process of photoelectric response remains a great challenge. In this study, a kind of Multi-walled carbon nanotubes loaded Alpha-FeO (CNTs/α-FeO) heterostructure composite is successfully prepared via the one-step method. Due to the synergistic effect in the as-prepared CNTs/α-FeO, the defect sites and oxygen-containing functional groups of CNTs can dramatically improve the interface charge separation efficiency and prevent the aggregation of α-FeO.

Synthesis and enhanced microwave absorption properties: a strongly hydrogenated TiO nanomaterial.

Due to its improved physical and chemical performances, a strongly hydrogenated TiO was designed and produced successfully by using a sealing-transfer reduction method at a relatively low temperature (425 °C). The microstructures, electromagnetic and microwave absorbing properties were investigated in detail. Experimental results revealed that: (1) the minimum reflection loss (RL) value of the hydrogenated TiO up to -53.

Constructing Two-, Zero-, and One-Dimensional Integrated Nanostructures: an Effective Strategy for High Microwave Absorption Performance.

A novel "201" nanostructure composite consisting of two-dimensional MoS nanosheets, zero-dimensional Ni nanoparticles and one-dimensional carbon nanotubes (CNTs) was prepared successfully by a two-step method: Ni nanopaticles were deposited onto the surface of few-layer MoS nanosheets by a wet chemical method, followed by chemical vapor deposition growth of CNTs through the catalysis of Ni nanoparticles. The as-prepared 201-MoS-Ni-CNTs composites exhibit remarkably enhanced microwave absorption performance compared to Ni-MoS or Ni-CNTs. The minimum reflection loss (RL) value of 201-MoS-Ni-CNTs/wax composites with filler loading ratio of 30 wt % reached -50.

Metal-free carbon nanotubes: synthesis, and enhanced intrinsic microwave absorption properties.

In order to clearly understand the intrinsic microwave absorption properties of carbon nanomaterials, we proposed an efficient strategy to synthesize high purity metal-free carbon nanotubes (CNTs) over water-soluble K2CO3 particles through chemical vapor decomposition and water-washing process. The comparison results indicated the leftover catalyst caused negative effects in intrinsic microwave absorption properties of CNTs, while an enhanced microwave absorption performance could be observed over the metal-free CNT sample. Moreover, the results indicated that the microwave absorption properties could be tuned by the CNT content.

To Study Juvenile xanthogranuloma (JXG) in the nasal cavity, raise the level of diagnosis and treatment for this disease. We reported a case with JXG and reviewed the literatures. JXG in nasal vestibule is ex tremely rare.

[Effect of negative life events on tinnitus patients quality of life].

Objective: To study the relationship between negative life events and quality of life of tinnitus patients, and explore the role of negative life events in psychological counseling and rehabilitation of tinnitus.

Method: Sixty-one cases of tinnitus patients and 61 normal controls were tested with tinnitus handicap inventory and life event scale, scores were compared and the associated analysis was made.

Result: Stimulating quantity of negative life events in the tinnitus group, compared with the control group was statistically different (Z = -2.

[The relationship between tinnitus severity and anxiety].

Objective: To evaluate the correlation between tinnitus severity and anxiety experienced by patients in order to explore its role in the rehabilitation of the tinnitus.

Method: A total of 119 patients complaining of tinnitus were recruited in a cross-sectional survey. Correlation was studied by series of instruments including tinnitus general questionnaire, tinnitus handicap inventory (THI) and self-rating anxiety scale (SAS).
