[Ecological Environment Dynamical Evaluation of Hutuo River Basin Using Remote Sensing].

Hutuo River Basin straddles Shanxi and Hebei provinces, and Hutuo River was once cut off due to economic development and urban expansion after 2000; however, with the national emphasis on ecological civilization and the implementation of the South-North Water Diversion Project, the ecological protection of Hutuo River Basin has been significantly improved. MODIS data, Landsat data, and night light remote sensing data were selected based on the google earth engine (GEE) platform, and a new evaluation index system was generated by combining the biological richness index, vegetation cover index, land stress index, and pollution load index in the ecological environment index (EI) and the humidity index in the remote sensing ecological index (RSEI), using the variation coefficient method and entropy weighting method to assign weights to these indices. An ecological environment evaluation model was constructed to evaluate and classify the ecological environment quality of Hutuo River Basin from 2000 to 2020, and the driving factors were interpreted by using geographic probes.

[Sensitization Spectrum of 16 362 Patients with Allergic Diseases in Peking University Third Hospital].

Objective To retrospectively analyze the sensitization spectrum of 16 362 patients with allergic diseases treated in the Peking University Third Hospital and provide reference for the prevention and treatment of allergic diseases.Methods A total of 16 362 patients with allergic diseases treated in the Peking University Third Hospital from January 2009 to September 2021 were selected.The serum levels of total IgE and antigen-specific IgE(sIgE)were determined.

Spontaneous quantitative processing in Chinese singular and plural picture naming: An event-related potentials analysis.

Chinese nouns lack inflection and cannot reflect the quantitative relationship between singular and plural numbers. However, neural processes of picture naming are different from those of words. We assume that Chinese single and plural picture naming is different, and they may involve quantitative processing.

Matrix Metalloproteinase 3: a Novel Effective Biomarker for Predicting the Mortality and the Severity of Pneumonia.

Background: Matrix metalloproteinase 3 (MMP3) is known as an inflammatory factor; however, the effectiveness of MMP3 for diagnosis of pneumonia and predicting outcomes is unclear. We evaluated the diagnostic and prognostic value of serum MMP3 in patients with pneumonia.

Methods: One hundred and eighty-five patients with pneumonia and 52 healthy controls were enrolled.

Risk factors for pulmonary embolism in patients with COVID-19: a systemic review and meta-analysis.

Purpose: To detect the risk factors for pulmonary embolism (PE) in patients with COVID-19.

Methods: Studies were searched for in PubMed, Cochrane Library, Web of Science, and EMBASE. Two authors independently screened articles and extracted data.

Suppression of Gut Bacterial Translocation Ameliorates Vascular Calcification through Inhibiting Toll-Like Receptor 9-Mediated BMP-2 Expression.

Aims: Vascular calcification (VC) is a primary risk factor for cardiovascular mortality in chronic renal failure (CRF) patients; thus, effective therapeutic targets are urgently needed to be explored. Here, we identified the role of intestinal bacterial translocation in CRF-related VC.

Methods And Results: Antibiotic supplementation by oral gavage significantly suppressed intestinal bacterial translocation, CRF-related VC, and aortic osteogenic gene and Toll-like receptor (TLR) gene expression in CRF rats.

Preoperative practice of surgical position reduces postoperative pain and discomfort in patients receiving kidney surgeries: a nonrandomized pilot study.

Objective: Prolonged maintenance of surgical position often results in postoperative pain and discomfort in patients. The present study aimed to investigate the effect of preoperative practice of surgical position on postoperative pain and general comfort in patients receiving kidney surgeries.

Methods: For this nonrandomized pilot study, 74 patients receiving kidney surgeries were selected using the probability sampling method.

[Effects of As2O3 on the Proliferation, Differentiation and Apoptosis of HL-60 Cells and Its Related Mechanisms].

Objective: To investigate the effects of arsenic trioxide (As2O3) on the proliferation, differentiation and apoptosis of HL-60 cells in vitro and explore the underlying mechanisms.

Methods: After HL-60 cells were treated with different concentration of As2O3, the cell proliferation was determined by MTS/PES method, the differentiation state was detected by the nitroblue tetrazolium (NBT) reduction test; flow cytometry was used to analyze the apoptosis and expression of CD11b. In addition, SYBR Green real-time RT-PCR was used to measure the mRNA levels of C-FES, BCL-2, BAX, survivin , P21 and P27.

Interferon-α combined with lamivudine versus lamivudine monotherapy for the emergence of YMDD mutations in chronic hepatitis B infection: a meta-analysis of randomized controlled trials.

Background/aims: Tyrosine-methionine-aspartate-aspartate (YMDD) mutations were the main limitation of lamivudine (LAM) for treating chronic hepatitis B (CHB). The aim of this study was to evaluate whether LAM combined with IFN-α offer advantage over lamivudine monotherapy for the occurrence of YMDD mutations in CHB using a meta-analysis.

Methodology: We searched electronic databases and calculated the odds ratios (OR) with their 95% confidence intervals (CI) and pooled the results.

Autophagy activation attenuates renal ischemia-reperfusion injury in rats.

Ischemia-reperfusion (I/R) injury is a leading cause of acute kidney injury (AKI), which is a common clinical complication but lacks effective therapies. This study investigated the role of autophagy in renal I/R injury and explored potential mechanisms in an established rat renal I/R injury model. Forty male Wistar rats were randomly divided into four groups: Sham, I/R, I/R pretreated with 3-methyladenine (3-MA, autophagy inhibitor), or I/R pretreated with rapamycin (autophagy activator).
