A simplified protocol for individualized regional citrate anticoagulation for hemodialysis: A single-center, randomized clinical study.

Introduction: The lack of individualized treatment protocols and complicated procedures are important factors limiting the use of regional citrate anticoagulation (RCA) technology in hemodialysis. This study aims to validate the safety and efficacy of a simplified individualized RCA protocol for hemodialysis.

Materials And Methods: From June 2019 to August 2019, 45 patients with active bleeding or bleeding tendency undergoing maintenance hemodialysis in the Nephrology Department of the First Affiliated Hospital of Nanchang University were randomly divided into a modified conventional RCA protocol group with a low-flux dialyzer, a simplified individualized RCA protocol group with a high-flux dialyzer, and a simplified individualized RCA protocol group with a low-flux dialyzer.

Diffusive flux of CH and NO from agricultural river networks: Regression tree and importance analysis.

River networks in subtropical agricultural hilly region become an inconvenient greenhouse gas (GHG, methane and nitrous oxide) source because of the influence of human activities, which has caused large uncertainties for refinement of national GHG inventories and their global budget. Based on field monitoring experiments at high temporal resolution, we employed regression tree and importance analysis to identify quantitatively factors that influence the diffusive flux of GHGs to provide a scientific basis for reducing GHG emissions and controlling regional carbon and nitrogen losses. The results indicate that significant spatiotemporal variation of methane (CH) nitrous oxide (NO) diffusion occurs in all the four reaches (W1, W2, W3 and W4) of Tuojia river networks.

Assessment of Indirect NO Emission Factors from Agricultural River Networks Based on Long-Term Study at High Temporal Resolution.

Assessment of indirect emission factors (EF) of nitrous oxide (NO) from agricultural river networks remains challenging, and results are uncertain due to limited data availability. This study compared two methods of assessing EF using data from long-term observations at high temporal resolution in a typical agricultural catchment in subtropical central China. The concentration method (method 1) and the Intergovernmental Panel on Climate Change (IPCC) 2006 method (method 2) were employed to evaluate the emission factor.

[Clinical and genetic features of ring chromosome 13 syndrome: an analysis of one case].

A girl aged 5 months was admitted due to developmental delay. Physical examination showed delayed physical development, unusual facies (microcephalus, hypertelorism, low-set ears, wide nasal bridge, and short philtrum), and an absence of the labium minus at one side. The peripheral blood karyotype was 46,XX,r(13)(p11q33)[82]/45,XX,-13[10]/46,XX,r(13;13)(p11q33;p11q33)[8], and array-based comparative genomic hybridization showed an 87.

Tissue engineered esophagus scaffold constructed with porcine small intestinal submucosa and synthetic polymers.

Acellular porcine small intestinal submucosa (SIS) has been successfully used for reconstructing esophagus with half circumferential defects. However, repairing full circumferential esophageal defects with SIS has been restricted due to the latter's poor mechanical properties. In the present study, synthetic polyesters biomaterial poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) and poly(lactide-co-glycolide) (PLGA) have been used to improve the mechanical properties of SIS.

Association of LAPTM4B gene polymorphism with breast cancer susceptibility.

Background: Lysosome associated protein transmembrane 4 beta (LAPTM4B) was a cancer-associated gene that is mapped to chromosome 8q22 with seven exons and six introns. LAPTM4B gene polymorphism has been reported to be significantly associated with susceptibility of several solid tumors.

Methods: We performed a case-control study was to investigate the association between LAPTM4B polymorphism and the risk of breast cancer in 732 breast cancer patients and 649 controls.
