[Predictive value of peripheral blood lymphocyte subsets for children with intravenous immunoglobulin-resistant Kawasaki disease].

Objectives: Based on peripheral blood lymphocyte subsets and common laboratory test indexes, this study aimed to construct a predictive scoring system for intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD).

Methods: Children hospitalized in Tianjin Children's Hospital from January 2021 to March 2023 were included in the study (185 cases of IVIG-sensitive KD and 41 cases of IVIG -resistant KD). Forty-six healthy children matched for age and gender were selected as controls.

The binding properties of copper and lead onto compost-derived DOM using Fourier-transform infrared, UV-vis and fluorescence spectra combined with two-dimensional correlation analysis.

Three dissolved organic matter (DOM) samples were obtained from municipal solid wastes at the initial (C0), high-temperature (C7) and mature (C51) period during composting. Two-dimensional correlation spectroscopy (2D-COS) analysis on Fourier-transform infrared (FTIR), ultraviolet visible (UV-vis), and synchronous fluorescence spectra (SFS) were used to investigate the metal binding properties of compost-derived DOM. Synchronous and asynchronous maps of 2D-FTIR-COS of DOM-Cu(II) and DOM-Pb(II) were similar, however, the susceptibility and binding sequence of the corresponding spectral region was different.

Insights into the pollutant-removal performance and DOM characteristics of stormwater runoff during grassy-swales treatment.

The water purification performance of grassy swales for treating stormwater road runoff was evaluated using a simulated experimental device in two different seasons. The results showed that the removal rates for total suspended solids (TSS), chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) reached 89.90%, 56.

[Evolution pattern of impervious surface in the Yuqiao Reservoir Watershed, Tianjin, China during the process of urbanization.].

Imperviousness in watershed is a key index to measure urbanization status which exerts an important impact on both eco-hydrological process and spatio-temporal pattern. Taking Yuqiao Reservoir Watershed as a case study area, based on the ENVI 5.1 software, the basic impervious surface information was extracted from remote sensing images taken in 1984, 1994, 2004 and 2013.

Light Absorption Enhancement of Silicon-Based Photovoltaic Devices with Multiple Bandgap Structures of Porous Silicon.

Porous-silicon (PS) multi-layered structures with three stacked PS layers of different porosity were prepared on silicon (Si) substrates by successively tuning the electrochemical-etching parameters in an anodization process. The three PS layers have different optical bandgap energy and construct a triple-layered PS (TLPS) structure with multiple bandgap energy. Photovoltaic devices were fabricated by depositing aluminum electrodes of Schottky contacts on the surfaces of the developed TLPS structures.

Isolation, Purification, and Structural Identification of an Antifungal Compound from a Trichoderma Strain.

Trichoderma strain T-33 has been demonstrated to have inhibitory effect on the fungus species Cytospora chrysosperma. Here, an active antifungal compound was obtained from Trichoderma strain T-33 extract via combined separation technologies, including organic solvent extraction, liquid chromatography, and thin-layer chromatography. The purified compound was further characterized by advanced analytical technologies to elucidate its chemical structure.

[Reiter's syndrome in children: a clinical analysis of 22 cases].

Objective: To study the clinical features of Reiter's syndrome (RS) in children.

Method: Twenty-two patients with RS were referred to our department between August 2002 and September 2008. Their clinical features were analyzed retrospectively.

Blood markers for the prognosis of ischemic stroke: a systematic review.

Background And Purpose: The performance of validated prognostic clinical models in acute ischemic stroke might be improved by addition of data on blood biomarkers.

Methods: We searched Medline and EMBASE from 1966 to January 2007 for studies of blood markers in patients with ischemic stroke and an assessment of outcome (death, disability, or handicap). We adopted several strategies to reduce bias.

[Macrophage activation syndrome in children with rheumatic disorders: a retrospective study on 6 patients].

Objective: To study the clinical manifestations of rheumatic disorders with macrophage activation syndrome (MAS) in children.

Methods: The authors characterized MAS by carrying out a retrospective study on patients who were identified during the past 12 years in Tianjin Children's Hospital.

Results: Six cases (4 females, 2 males) were studied.

[Clinical characteristics of children with enthesitis related arthritis].

Objective: To study clinical characteristics of children with enthesitis related arthritis (ERA).

Methods: Twelve patients fulfilling the international league of associations for rheumatology (ILAR) criteria for classification of juvenile idiopathic arthritis (JIA) and ERA were referred to our department between August and November, 2002. Their gender, age, family history, clinical manifestations, imaging data, laboratory data and treatment regimens were analyzed retrospectively.
