Development and feasibility of an echocardiography-guided tip location program for central venous catheter implantation.

This is a prospective observational study designed to develop an echocardiography-guided tip location program for central venous catheter (CVC) implantation, and to assess the feasibility and the accuracy of the program. First, a multidisciplinary expert committee designed an echocardiography-guided tip location program; then, a pilot prospective observational study was conducted to assess the feasibility of the program in a vascular access clinic in a tertiary hospital. A total of 186 patients participated in the study.

Development of an educational program for ultrasound-based tip location during placement of PICC-port to improve the competence of specialized nurse.

Objectives: To create an educational program and provide a valid, evidence-based course for ultrasound-based tip location during placement of PICC-port for specialized nurses.

Materials And Methods: We designed three phases for program development. Phase 1: summarizing the evidences as a knowledge foundation; Phase 2: developing an educational program for ultrasound-based tip location during placement of PICC-port; Phase 3: expert panel to validate the developed program.

Acute fatty liver of pregnancy causing multiple organ dysfunction syndrome in a Chinese intensive care unit.

Acute fatty liver of pregnancy (AFLP) is a rare but severe condition associated with high rates of maternal and foetal morbidity and mortality. Timely discontinuation of pregnancy, professional supervision and appropriate management are helpful for a successful discharge. This article reports the presentation and nursing care of a pregnant woman who was diagnosed with AFLP and discharged from the intensive care unit (ICU) after a prolonged hospitalization.

Livestock grazing-exclusion under global warming scenario decreases phosphorus mineralization by changing soil food web structure in a Tibetan alpine meadow.

The exclusion of grazing has been used extensively in alpine meadows on the Tibetan Plateau. Studies, however, have shown reported recent trends of decreasing concentrations of soil nutrients because of grazing exclusion and climate change. The effects of excluding grazing on the soil biogeochemical process of phosphorus cycling in alpine meadows are unclear, especially under climatic warming.

Transverse incision versus longitudinal incision in the implantation of PICC-port: A before-after study.

Background: The peripherally inserted central catheter-port (PICC-port) technique is an innovation of the standard arm-totally implantable vascular access device. The design of surgical skin incision may have an important impact on the postoperative life of patients, the cosmetic result is important for patient satisfaction as well.

Objectives: To compare two different incision methods in the implantation of PICC-port.

Application of nursing based on the authorization theory in asthmatic children aged 7 to 14 years.

Objective: To investigate the effect of a nursing model based on the authorization theory of asthma in children aged 7 to 14 years.

Methods: In total, 200 children who were 7 to 14 years with asthma in remission were recruited in this study. These children were admitted to our hospital and were randomly divided into the control group (n=100) and the experimental group (n=100).

Inorganic nitrogen uptake rate of Picea asperata curtailed by fine root acclimation to water and nitrogen supply and further by ectomycorrhizae.

Ectomycorrhizal (ECM) fungi colonization and function depend on soil water and nutrient supply. To study the effects of resource supply on ECM colonization and inorganic nitrogen (N) uptake by roots of Picea asperata seedlings, we conducted a study at the end of a 5-year long experiment consisting of five watering regimes (40, 50, 60, 80, and 100% of field capacity) and three NH NO application rates (0 [N0], 20 [N1], and 40 [N2] g N m  year ). We measured fluxes of ammonium ( ) and nitrate ( ) into colonized and uncolonized roots using noninvasive microtest technology.

Effect of intranasal oxytocin administration on self-other distinction: Modulations by psychological distance and gender.

Preliminary evidence indicates that intranasal oxytocin (OT) administration modulates one's ability to distinguish oneself from others (i.e., self-other distinction).

Intestinal morphology, immunity and microbiota response to dietary fibers in largemouth bass, Micropterus salmoide.

This study is aimed at identifying the effects of dietary fiber on gut health, as well as the association between that understanding and fiber consumption in fish. A total of 300 juvenile largemouth bass (micropterus salmoides, initial average weight: 15.38 ± 0.

Characterization of Trichococcus paludicola sp. nov. and Trichococcus alkaliphilus sp. nov., isolated from a high-elevation wetland, by phenotypic and genomic analyses.

Two psychrotolerant facultative anaerobes, strains B7-2 and B5, were isolated from the Zoige Wetland on the Qinghai-Tibetan Plateau. The 16S rRNA gene sequences of strains B7-2 and B5 shared high similarity (>99 %) with those of the type strains of the genus Trichococcus, while their digital DNA-DNA hybridization values with each other (49 %) and with the reference type strains (48-23 %) were lower than 70 %, which suggest that they represent two novel species of the genus Trichococcus. Cells of strains B7-2 and B5 were immotile cocci, grew in the temperature range of 4-37 °C (optimum 25 °C) and were alkaliphilic with optimum growth at pH 9.

Photoprotection regulated by phosphorus application can improve photosynthetic performance and alleviate oxidative damage in dwarf bamboo subjected to water stress.

Water and nutrients, particularly phosphorus (P), are the two most limiting factors for dwarf bamboo growth in tropical and subtropical areas. Dwarf bamboo is highly sensitive to water stress and often causes severe P deficiency in its growing soils due to the characteristics of shallower roots and expeditious growth. However, little is known about its photoprotective response to soil water deficit and the underlying mechanisms regulated by P application.
