A product-induced catalytic amplification (PICA) strategy had been developed for miRNA-21 detection based on DNA tetrahedron module (DTM). The produced DNA fragment could open hairpin structure and increase the concentration of catalyst, accelerating the circular cleavage reaction on DTM by DNAzyme cleavage. The continuously cleavage of DNAzyme on DTM resulted the greatly enhancement of signal.

While it typically affects the liver and spleen, it is exceptionally rare in the digestive tract. We present a special case of EBV + inflammatory FDC sarcoma arising in the colon with clonal immunoglobulin (IG) gene rearrangement.

Novel antibacterial therapeutic strategies must be developed. The biological effects of glabridin on MDR-AB were investigated in this study.

The purpose of this study was to clarify the mechanism of the carbapenems and colistin co-resistance in Enterobacter cloacae Complex (ECC) strains.
Results: This study showed that the mechanisms of carbapenem resistance in this study are: 1.
Purpose: The emergence of colistin resistance among Gram-negative bacteria (GNB) poses a serious public health threat. Therefore, it is necessary to enhance the antibacterial activity of colistin through the combination with other drugs. In this study, we demonstrated the synergistic activity and the possible synergy mechanism of colistin with PFK-158 against colistin-resistant GNB, including non-fermenting bacteria and Enterobacteriaceae.

This study aims to explore the NIT resistance mechanisms and epidemiological characteristics of clinical isolates.
Patients And Methods: A total of 633 clinical isolates was obtained from urine samples in a clinical teaching hospital during 2017-2018.

Background: Bloodstream infection (BSI) caused by multidrug-resistant Acinetobacter baumannii (MDR-AB) has been increasingly observed among hospitalized patients. The following study analyzed the epidemiology and microbiological characteristics of MDR-AB, as well as the clinical features, antimicrobial treatments, and outcomes in patients over a six years period in China.
Methods: This retrospective study was conducted in a large tertiary hospital in China between January 2013 and December 2018.
Colistin became the critical treatment option for multidrug-resistant Gram-negative bacteria (GNB); however, resistance to colistin is increasingly being reported among clinical isolates. New therapy strategies should be considered nowadays. The aim of this study was to investigate the activity of a novel β-lactam/β-lactamases inhibitor ceftazidime-avibactam (CZA) alone and in combination with amikacin against colistin-resistant Gram-negative pathogens.

With the widespread of multidrug-resistant bacteria and the lack of effective antibacterial drugs, fosfomycin has gradually attracted attention as an "old drug." Thus, investigating the resistance mechanisms and epidemiology of fosfomycin-resistant is an urgent requirement.

Objectives: Triclosan is usually employed as a disinfectant in a wide range of medical and consumer care products, which may have imposed a selective pressure on bacteria. This study was designed to evaluate the resistance mechanisms of triclosan and molecular epidemiology of triclosan-resistant isolates of Acinetobacter baumannii in Wenzhou, China.
Methods: A collection of 626 A.
Purpose: To investigate the protective roles of pyracantha fortune fruit extract (PFE) on acute renal toxicity induced by cadmium chloride (CdCl2) in rats.
Methods: Rats were pretreated with PFE and consecutively injected with CdCl2 (6.5 mg/kg) for 5 days.
Objectives: Nursing is often regarded as a female-dominated profession. Many nursing curricula are received by mainly female students. It is uncertain how male students behave in this environment of nursing education in hospitals and universities.
