ABSTRACT

Objective:To explore the correlation between early inflammation indicators and the severity of coronavirus disease 2019 (COVID-19).Methods:A retrospective study was conducted. Patients with COVID-19 admitted to Wenzhou Central Hospital from January 17 to February 14, 2020 were enrolled. The general information, chest CT before admission, the first laboratory parameters and chest CT within 24 hours after admission were collected. Patients were followed up for 30 days after the first onset of dyspnea or pulmonary imaging showed that the lesions progressed more than 50% within 24 to 48 hours (according to the criteria for severe cases) as the study endpoint. According to the endpoint, the patients were divided into two groups: mild type/common type group and severe/critical group, and the differences in general information and inflammation index of the two groups were compared. Logistic regression was used to analyze the inflammation index and the severity of COVID-19. Receiver operating characteristic (ROC) curve was draw to evaluate the predictive value of early inflammation indicators for severe/critical in patients with COVID-19.Results:A total of 140 patients with COVID-19 were included, 74 males and 66 females; the average age was (45±14) years old; 6 cases (4.3%) of mild type, 107 cases (76.4%) of common type, and 22 cases (15.7%) of severe type, 5 cases (3.6%) were critical. There were significantly differences in ages (years old: 43±13 vs. 57±13), the proportion of patients with one chronic disease (17.7% vs. 55.6%), C-reactive protein [CRP (mg/L): 7.3 (2.3, 21.0) vs. 40.1 (18.8, 62.6)], lymphocyte count [LYM (×10 9/L): 1.3 (1.0, 1.8) vs. 0.8 (0.7, 1.1)], the neutrophil/lymphocyte ratio [NLR: 2.1 (1.6, 3.0) vs. 3.1 (2.2, 8.8)] and multilobularinltration, hypo-lymphocytosis, bacterial coinfection, smoking history, hyper-tension and age [MuLBSTA score: 5.0 (3.0, 5.0) vs. 5.0 (5.0, 7.0)] between mild/common group and severe/critical group (all P < 0.05). Univariate Logistic regression analysis showed that CRP, NLR, MuLBSTA score, age, and whether chronic diseases were associated with the severity of COVID-19 [odds ratio ( OR) and 95% confidence interval (95% CI) were 1.037 (1.020-1.055), 1.374 (1.123-1.680), 1.574 (1.296-1.911), 1.082 (1.042-1.125), 6.393 (2.551-16.023), respectively, all P < 0.01]. Further multivariate Logistic regression analysis showed that CRP and MuLBSTA score were risk factors for the development of COVID-19 to severe/critical cases [OR and 95% CI were 1.024 (1.002-1.048) and 1.321 (1.027-1.699) respectively, both P < 0.05]. ROC curve analysis showed that the area under the curve for CRP and MuLBSTA score to predict severe/critical cases were both 0.818, and the best cut-off points were 27.4 mg/L and 6.0 points, respectively. Conclusion:CRP and MuLBSTA score are related to the severity of COVID-19, and may have good independent predictive ability for the development of severe/critical illness.

ABSTRACT

OBJECTIVE@#To analyze the phenotype and genetic basis for a pedigree affected with hereditary coagulation factor XI deficiency.@*METHODS@#Activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB), FXI activity (FXI:C) and the antigen of FXI (FXI:Ag) were determined for the proband and members from his pedigree. Sanger sequencing was used to analyze all exons, exon-intronic boundaries, as well as the 5'- and 3'- untranslated regions of the F11 gene. Suspected variants were verified in her family members and confirmed by reverse sequencing. The impact of the variants on the protein function was predicted by using PolyPhen-2 and SIFT software. The protein structure and amino acid interaction were analyzed by using Swiss-PdbViewer.@*RESULTS@#The APTT, FXI:C and FXI:Ag of the proband and her sister were significantly reduced to 73.0 s, 10.0%, 15.0% and 87.1 s, 2.0% and 11.5%, respectively. APTT of some family members was slightly prolonged, and FXI:C and FXI:Ag also decreased to various extents. DNA sequencing revealed that the proband and her sister have carried compound heterozygous variants of c.738G>A (p.Trp228stop) and c.938G>T (p.Ser295Ile) respectively in exons 7 and 9 of the F11 gene. Her father, sister and daughter were heterozygous for the c.738G>A (p.Trp228stop) variant, while her mother and nephew were heterozygous for the c.938G>T (p.Ser295Ile). Both PolyPhen-2 and SIFT predicted that the p.Ser295Ile variant is likely to be deleterious and can affect the protein function. Modeling analysis indicated that the p.Ser295Ile variant may lead to disruption of a hydrogen bond, resulting in alteration of protein structure and instability.@*CONCLUSION@#The compound heterozygous c.738G>A (p.Trp228stop) and c.938G>T (p.Ser295Ile) variants of the F11 gene probably underlie the decreased FXI level in this pedigree.

ABSTRACT

OBJECTIVE@#To explore the molecular pathogenesis for a pedigree affected with hereditary coagulation factor XII (FXII) deficiency.@*METHODS@#Potential variant of the F12 gene was analyzed by PCR and Sanger sequencing. Expression plasmids were constructed by site-directed mutagenesis based on the wild-type and transiently transfected into 293T cells. FXII:C and FXII:Ag of the expression products were determined in the supernatant and cell lysate. Western blotting was used to verify the identify of the protein.@*RESULTS@#Gene sequencing revealed that the proband has carried 46TT genetype and heterozygous p.Glu502Lys variants in exon 13, and a heterozygous p.Gly542Ser variant in exon 14 of the F12 gene. Transfection experiment suggested that the FXII:C and FXII:Ag of p.Glu502Lys variant in the supernatant were 28% and 24%, compared with the wild-type (100%) and FXII:Ag of cell lysates was 39% compared to the wild-type (100%). The FXII:C and FXII:Ag of p. Gly542Ser variant in the supernatant were 32% and 17% and the FXII:Ag of cell lysates was 59%.@*CONCLUSION@#The 46TT genetype, p.Glu502Lys and p.Gly542Ser variants of the F12 gene probably underlie the low FXII level in the proband. As shown by in vitro experiment, the p.Glu502Lys and p.Gly542Ser variants can both inhibit the synthesis and secrection of the FXII protein.

ABSTRACT

Objective To establish a visualized nomogram with early predictive value for the severity of first-onset acute pancreatitis ( AP ) . Methods 706 cases of first-onset AP patients admitted to the First Affiliated Hospital of Wenzhou Medical University within 72 hours from January 2013 to January 2016 were collected. According to the revised Atlanta classification of AP in 2012, AP patients was divided into non-severe pancreatitis ( NSAP, also called mild acute pancreatitis and moderately severe acute pancreatitis) group and severe acute pancreatitis ( SAP) group. The demographic data ( age, body mass index and admission time, etc) and laboratory tests (serum amylase, blood sugar, albumin, white blood cells, creatinine, urea nitrogen) were collected and statistically analyzed. Logistic univariate and multivariant regression analysis were performed based on the relevant clinical indicators. The statistically significant indicators were used to obtain regression equations. The R-language software was used to obtain the visualized nomogram via LR model, which was further validated by ROC curve analysis. Results In univariate logistic regression analysis, the OR ( 95%CI) values of blood glucose, creatinine at admission and 24 h after admission, urea nitrogen at admission and 24 h after admission, white blood cell, albumin in NSAP group and SAP group were 1. 132(1. 080-1. 186), 1. 019(1. 013-1. 025), 1. 026(1. 020-1. 033), 1. 066(1. 035-1. 099), 1. 333(1. 241-1. 432), 1. 083 (1.032-1.136), and 0.853(0.811-0.889), and all the differences were statistically significant (all P values <0. 05). Multivariate logistic regression analysis showed that the regression equation of the LR model was Y= -2. 657-0. 116 × albumin(g/L) +0. 082 × white blood cell( × 109/L) +0. 118 × glycemia(mmol/L) +0. 022 × 24 h after admission creatinine (μmol/L). A total score of more than 60 points on the nomogram predicted the possibility of SAP. If the total score exceeded 130, the possibility of SAP may be up to 14% or more. Furthermore, the ROC curve analysis confirmed that the sensitivity and specificity of LR model established in this study for predicting of SAP were superior to those of urea nitrogen, creatinine and BISAP score alone by AUC, respectively. Conclusions This nomogram may be a useful clinical tool for predicting the severity of the first-onset acute pancreatitis.

ABSTRACT

Objective To observe the effects of insulin caliper for blood glucose control on glycemic central tendency, fluctuation and incidence of hypoglycemia in patients with sepsis, and evaluate its application value. Methods One hundred sepsis patients with significant hyperglycemia from December 2015 to December 2017 were selected. All patients needed continuous intravenous insulin infusion to maintain blood glucose. The patients were divided into caliper group and conventional group by random digits table method with 50 cases each, patients of 2 groups adopted an insulin dose modification scheme based on insulin caliper for blood glucose control and paper-based insulin dose modification scheme respectively to control blood glucose. Finally, 92 cases completed the study, including 47 cases in caliper group and 45 cases in conventional group. Blood glucose was measured every 2 hours 0 to 12 hours after intravenous insulin and every 4 hours 16 to 72 hours after intravenous insulin. The incidence of hypoglycemia, insulin dose, ICU time, total hospital stay and hospitalization cost were observed. The proportion of hypoglycemia to total blood glucose measurement, proportion of achieving the glucose control target at each time point, glycemic coefficient of variance, glycemic lability index (GLI) and mean amplitude of glycemic excursion (MAGE) were calculated. Results A total of 1 379 blood glucose values were obtained in caliper group, and a total of 1 332 blood glucose values were obtained in conventional group. There were no statistical difference in blood glucose values 0 to 12 hours after intravenous insulin between 2 groups (P>0.05). The blood glucose values 16 to 72 hours after intravenous insulin in caliper group were significantly lower than those in conventional group, and there were statistical differences (P<0.01 or <0.05). There were no statistical differences in glycemic coefficient of variance, insulin dose, incidence of hypoglycemia and proportion of hypoglycemia to total blood glucose measurement between 2 groups (P>0.05). The GLI and MAGE in caliper group were significantly lower than those in conventional group: 12.96 (8.73, 19.58) vs. 23.27 (13.07, 44.61) and (0.66 ± 0.22) mmol/L vs. (0.87 ± 0.28) mmol/L, the proportion of achieving the glucose control target at each time point was significantly higher than that in conventional group: 41.99% (579/1 379) vs. 27.18% (362/1 332), and there were statistical differences (P<0.01). There were no statistical differences in ICU time, total hospital stay, hospitalization cost, nosocomial infection rate and prognosis between 2 groups (P>0.05). Conclusions For emergent and critical patients with sepsis, insulin caliper for blood glucose control presents favorable application value for achieving glucose control target, reducing glycemic fluctuation, lowering the incidence of hypoglycemia, low cost and good operability.

ABSTRACT

Many studies have suggested that visfatin expression is closely related to the occurrence of insulin resistance [IR], while the precise role of visfatin in the regulation of IR in chronic hepatitis C [CHC] is not clear. We investigated fasting glucose, fasting insulin [FINS], C peptide, visfatin, visfatin mRNA, interleukin [IL]-6, tumor necrosis factor [TNF]-alpha, C-reactive protein [CRP] and other parameters of 315 patients with CHC and 150 control cases in China. Meanwhile we collected clinical and other laboratory data for further analysis. Compared with the control group, the CHC group had a significant increase in alanine aminotransferase [ALT], aspartate aminotransferase [AST], the AST to platelet ratio index [APRI], ratio of AST to ALT [AAR], gammaglutamyl trans-peptidase, IL-6, TNF-alpha, visfatin, visfatin mRNA, FINS, fasting C peptide, and IR index. The visfatin, visfatin mRNA, insulin, IR index, Homabeta cell function index [HBCI], and fasting beta-cell function index [FBCI] of the subjects with high body mass index [BMI] from the CHC sub-group were significantly higher than the normal BMI sub-group of CHC patients. We found a positive correlation between visfatin, visfatin mRNA and BMI, IL-6, TNF-alpha, and IR index. Our data suggest that visfatin may be related to IR in Chinese CHC patients

ABSTRACT

ObjectiveTo investigate the effect of bone marrow-derived mesenchymal stem cells (MSCs) on gene and protein expression of toll-like receptor, TLR2/4 of the rat alveolus macrophages so as to discuss the effect of MSCs transplantation on the early inflammatory mediators and the regulatory mechanism of the inflammatory cascade.MethodsThe alveolus macrophages were randomly divided into the PBS control group (n = 24), MSCs control group (n = 24), lipopolysaccharide (LPS) control group (n=24) and LPS + MSCs treatment group (n =24).All groups were taken time-points of 1, 3,6, 12 hours.Positive cell rate of MSCs with surface mark and the expression level of TLR2/4 protein on macrophage were detected by flow cytometry.The mRNA level of TLR2/4 expression on macrophage was detected by RT-PCR and the concentrations of TNF-o in cell culture supernatants by ELISA at the different time points.ResultsCompared with the PBS control group and MSCs control group, TLR2/4 mRNA and protein levels were significantly up-regulated, markedly increased at one hour and peaked at 12 hours (P <0.01) and the TNF-α concentrations in cell culture supernatants were significantly up-regulated and peaked at 6 hours in the LPS control group (P < 0.01).Compared with the LPS control group, mRNA and protein level of TLR2/4 and TNF-o concentrations in the cell culture supernatants of the LPS + MSCs group were markedly down-regulated (P < 0.01).ConclusionsWith LPS stimulation, TLR2/4 mRNA and protein expressions as well as TNF-αt concentration increase, when the peak of the TNF-αt concentration appears slightly earlier, indicating that there may be a positive feedback loop between TLR2/4 expression and TNF-ot.MSCs can significantly reduce TLR2/4 mRNA and protein expressions as well as TNF-α concentration after LPS stimulation, indicating that MSCs can break up the positive feedback loop.

ABSTRACT

Objective To investigate the changes of cardiac function and myocardial apoptosis after limb ischemia reperfusion in rabbits.Methods Thirty rabbits were randomly divided into 3 groups:sham-operated control group (group SC),ischemia group (groupⅠ,8 hours of bilateral hind limb ischemia) and ischemia reperfusion group (group IR,4 hours of bilateral hind limb ischemia and 4 hours of reperfusion).Immunohistochemical studies and TUNEL were done to evaluate cell apoptosis.The SOD activity and MDA content in myocardial tissue and plasma LDH activity were determined. The left ventricular function were observed by physiology recording instrument.The cardiac histopathologic changes in experimental rabbits were observed.Results In group IR,the apoptosis index and expression of Bax were significantly increased compared with the other two groups.Similarly,ischemia reperfusion reduced SOD activity and enhanced LDH activity and MDA level,and the left ventricular function decreased in group IR.There was a positive correlation among the MDA content and the LDH activity,the expression of bax,the number of apoptosis cells.Under light microscope, myocardial impairment was found in group IR.Conclusion The myocardial injury occured and the left ventrieular function decreased after limb ischemia reperfusion,and they were associated with oxidative damage and apoptosis.

ABSTRACT

Objective To evaluate the dynamic change of the antithrombase and fibrinolytic function in the critical patients.Methods Eighty-seven patients hospitalized in ICU were studied. According to the clinical manifestation, all patients were divided into systemic inflammatory response syndrome (SIRS) group ( n = 68) and non-SIRS group ( n = 19), or multiple organ dysfunction syndrome (MODS) group ( n = 37) and non-MODS group (n = 50) respectively. Thirty-one healthy volunteers were selected for control in the same period. The intravenous blood samples were taken 1,3 and 5 days after ICU admission to measure platelet,count (PLT) , and the plasma levels of antithrombase activity (AT: A), plasminogen activity (PLG: A), fibrinogen (FIB) and D-dimer (D-D) concentrations.Results AT: A, PLG: A and PLT were lower and FIB and D-D levels higher in all patients than control levels (P
