The glycoproteins in the biological sample are low abundance and are susceptible to be inhibited and interfered by other non-glycoproteins.An enrichment step is usually required before the glycoprotein analysis, but the operation steps of conventional solid-phase-based glycoprotein enrichment methods are difficult to be compatible with the most classical enzyme-linked immune sorbent assay (ELISA) technique.In this study, a novel water-soluble dendrimer based boronic acid capture (DBC) material was developed using PAMAM 4.0 as the carrier and boronic acid as the affinity group.The method was applied to the detection of glycoproteins in human liver microsomes using ELISA.In this study, the DBC enrichment conditions were optimized by model glycoprotein, and then its sensitivity and anti-interference ability were investigated.This method was applied to the enrichment of glycoproteinsin human liver microsomal.The results showed that the enrichment selectivity of DBC for glycoprotein could be up to 100000 folds, and the enrichment signal of glycoprotein could be increased by 100 times.Therefore, the ELISA method using DBC as a novel enrichment material for glycoprotein had high sensitivity and selectivity in detection of biological samples with only one simple incubation step, which was useful for glycoproteins researches.

Objective:To illustrate a relatively complete knowledge system (e.g., research outputs, current hotspots, and future trends) in the sepsis field and to help scholars grasp the scientific research direction or clinical focus of treatment.Methods:The relevant literatures of sepsis during the time from 1985 to 2019 in Web of Science database were collected. Sepsis-related research contents were generated using softwares (CiteSpace 5.6.R2 and VOSviewer 1.6.13), which using data mining, information processing and knowledge map methods, to analyze the historical evolution and predict the development trend.Results:A total of 8 189 papers on sepsis were published. The volume of publications were increasing yearly from 1985 to 2019, and reached the top list of 1 276 in 2019. For research contents of sepsis, it has formed the basic characteristics of sepsis which focusing on epidemiological studies and animal experiments. Through cluster analysis, the researches mainly focused on six aspects: septic rat, necrotizingenterocolitis, sepsis-associated encephalopathy, acute kidney injury (AKI), gut-derived sepsis, and inflammatory mediator. And it presented the literature characteristics that related to the injury or dysfunction of intestines, brain, liver, kidney or other organs, but the heart and lung researches were more marginal. Additionally, based on the top key words with the strongest citation bursts, it reflected that the development trend of the continuous attention hotspots with "endotoxin" or "endotoxin shock", the significant attention hotspots with "inflammation", "immunity" and "multiple organ dysfunction syndrome" (MODS), and the novel burst attention hotspots with sepsis management including "diagnosis" and "chemotherapy".Conclusions:Through the hotspots and trends visualization of sepsis, the current researches are prefer to animal experiments, epidemiology, or other basic scientific aspects. Meanwhile, the researches are mostly focusing on inflammatory reaction, immune function or organ dysfunctions. Integrating the knowledge maps of hotspots and trends, based on researches of epidemiology, diagnosis, risk factors, pathogenesis, or treatment, we predict that the future scientific topics will concentrating on childhood sepsis, organ injury mechanism or intervention relating to MODS, and integrated management of sepsis by combining traditional Chinese medicine and Western medicine.
