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.

Objective:To investigate the effect of abnormal D-dimer level on the prognosis of patients with frontal lobe injury, and to provide a new idea for clinical diagnosis, treatment and prognosis evaluation of frontal lobe injury.Methods:A retrospective analysis was performed on 71 patients with traumatic brain injury (TBI) who were admitted to the Surgical Care Unit of the First Affiliated Hospital of Zhejiang University School of Medicine from November 1, 2020 to February 1, 2021. According to whether TBI involved in the frontal lobe, the patients were divided into the experimental group ( n = 44) and the control group ( n = 27). Clinical data including sex, age, body mass index (BMI), length of hospital stay, ISS trauma score, GCS coma score, qSOFA score, GOS prognostic score and coagulation index test results within 24 h of admission of the two groups were recorded, and the difference of each index between the two groups was compared. Results:① D-dimer levels were significantly higher in the experimental group than in the control group ( P<0.01); ② The incidence of complications in the experimental group was 40.9%, of which the incidence of lower limb vein thrombosis was 18.2%, and the incidence of complications in the control group was 18.5%, of which the incidence of lower limb vein thrombosis was 3.7%; there were statistical differences between the two groups ( P<0.05); ③ The average hospital stay of patients was 10.96 days in the control group, and 15.50 days in the experimental group with a statistically significant difference between the two groups ( P<0.05); ④ The 28-day mortality rate of patients in the experimental group was 18.2% and 7.4% in the control group. There was no significant difference in 28-day mortality between the two groups ( P>0.05); ⑤ The level of D-dimer was negatively correlated with GOS prognostic score in patients with frontal lobe injury ( r=-0.501, P<0.01). Conclusions:Patients with frontal lobe injury have increased D-dimer levels, increased incidence of complications, and longer hospital stay. There is a significant negative correlation between D-dimer level and prognosis in patients with frontal lobe injury. D-dimer can be used as a sensitive indicator to evaluate the prognosis of patients with frontal lobe injury. The higher the D-dimer level, the worse the prognosis of patients.

Objective: To investigate the association of SNPs in TET2 gene with the susceptibility and prognosis of sepsis. Methods: Ninety-nine patients diagnosed with sepsis and 107 controls were enrolled in the study. The septic patients were further divided into survivors (56 cases) and non-survivors (43 cases) according to the outcome of 28-day hospitalization. Patients without sepsis after major surgery were enrolled as the controls. The genotypes of the five loci (rs6839705, rs7670522, rs7679673, rs7698522 and rs10010325) with high minor allele frequency in the TET2 were screened according to the existing research reports and the SNP database of the NCBI website. The five loci were detected by TaqMan probe based allelic discrimination assays using real-time polymerase chain reaction (PCR). The data were calculated for genetic association study through χ² test and Fisher’s exact probability method. Results: There was no significant difference in genotype frequencies of the five tested SNPs in TET2 gene between septic patients and controls or between survivors and non-survivors in septic patients (P > 0.05). Furthermore, the allelic frequencies of the five SNPs between septic patients and controls or between survivors and non-survivors in septic patients also had no significant difference (P > 0.05). Conclusions This study showed that the five SNPs in TET2 gene (rs6839705, rs7670522, rs7679673, rs7698522, and rs10010325) were not associated with the susceptibility and prognosis of sepsis, which needs to be further confirmed by large-sample studies.

Objective To evaluate the feasibility of developing hospital acquired pneumonia (HAP) risk warning model in critically ill patients based on genomic copy number polymorphisms (CNPs) of the genes encoding human neutrophil peptides 1-3 (DEFA1/DEFA3).Methods Seventy-seven HAP patients (group HAP) and 109 non-HAP patients of matched age and sex in intensive care unit (ICU) (group NHAP) were enrolled in the study.The genomic CNPs of DEFA1/DEFA3 was determined by realtime quantitative polymerase chain reaction after extracting DNA from peripheral blood samples.The source of patients,condition of endotracheal intubation within 24 h after admission to ICU,Acute Physiology Score,Acute Physiology and Chronic Health Evaluation Ⅱ score,Sequential Organ Failure Assessment score,mechanical ventilation time,length of hospital and ICU stay and outcomes were obtained.The predictive model was developed using logistic regression through combining DEFA1/DEFA3 copy numbers and clinical characteristics (Acute Physiology Score and source of emergency) within 24 h after admission to ICU.The receiver operating characteristic curve was used to evaluate the predictive efficacy of the model.Results The copy numbers of DEFA1/DEFA3 were significantly lower in HAP group than in NHAP group (P ＜0.05).The area under the receiver operating characteristic curve of the predictive model developed through combining the DEFA1/DEFA3 copy numbers with clinical characteristics was 0.789 (95％ CI 0.724-0.854) when the model was used for predicting HAP.Conclusion CNPs of DEFA1/DEFA3 can be used to develop the HAP risk warning model in critically ill patients.

Objective: To investigate the changes in protein expression in patients with 1-bromopropane (1-BP) poisoning using high-throughput proteomic technique and to screen out protein markers. Methods: Serum samples were collected from 3 patients with 1-BP poisoning and 15 controls. The label-free proteomic tech-nique was used for the quantitation and identification of proteins expressed in these samples, and the results were compared between the patients with 1-BP poisoning and the control population. The bioinformatics tools were used to analyze the function of differentially expressed proteins. Results: Compared with the control popula-tion, the patients with 1-BP poisoning had >2-fold upregulation of 38 proteins and >2-fold downregulation of 68 proteins. The differentially expressed proteins were mainly involved in immune response, signal transduction, and stress response. Conclusion The proteins screened out may be potential protein markers for 1-BP poison-ing, which provides reliable and precise methods and thoughts for the diagnosis of 1-BP poisoning.

Objective To explore the correlation between pregnancy-related anxiety and serum 25 (OH)D level during early pregnancy. Methods A radioimmunoassay was used to determine the serum 25 (OH)D levels of 2 122 early pregnant women in Maanshan Maternal and Child Health Care Hospital, from June 2015 to 2016. Data were collected using a questionnaire. Results The mean serum 25(OH)D level was(29.71±32.27)nmol/L.About 15.2% of the subjects had adequate,22.6% had insufficient,45.1% had deficient,and 17.1% had severely deficient serum 25(OH)D levels.The type of housing and testing seasons were significantly associated with the serum 25(OH)D level.Single factor logistic regression analysis results show that pregnancy-related anxiety incidence in the group deficient in 25(OH)D was higher than that in the adequate group, which has a statistically significant difference (P<0.05). After adjusting for the maternal age,BMI,and educational level,multivariate logistic regression analysis results showed that the difference was statistically significant. Conclusion The serum 25(OH)D level in early pregnant women was inadequate. Furthermore, lack of serum 25(OH)D in early pregnancy and pregnancy-related anxiety were negatively correlated.
