ABSTRACT

Objective To investigate the value of magnetic resonance imaging-proton density fat fraction (MRI-PDFF) and FibroScan in the quantitative evaluation of liver fat content in patients with chronic hepatitis B (CHB). Methods A total of 96 patients with CHB who were hospitalized in Department of Hepatology, The Second Clinical Medical College of Guangzhou University of Chinese Medicine, from February 2017 to July 2020 were enrolled, and all patients were diagnosed based on liver pathological examination. MRI-PDFF and FibroScan were performed before surgery. According to the results of liver biopsy, the patients were divided into non-fatty liver disease group with 44 patients, mild fatty liver disease group with 33 patients, and moderate-to-severe fatty liver disease group with 19 patients. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Mann-Whitney U test was used for further comparison between two groups; Bonferroni correction was also performed. The receiver operating characteristic (ROC) curve was plotted to analyze the area under the ROC curve (AUC) of hepatic fat fraction (HFF) and controllable attenuation parameters (CAP) in the diagnosis of fatty liver disease and obtain their sensitivities, specificities, and optimal cut-off values. The intraclass correlation coefficient was used to investigate the consistency of MRI-PDFF data. Results The moderate-to-severe fatty liver disease group had a significant increase in MRI-PDFF HFF compared with the non-fatty liver disease group and the mild fatty liver disease group (all P < 0.05), and the mild fatty liver disease group had a significant increase in MRI-PDFF HFF compared with the non-fatty liver disease group( P < 0.05). The moderate-to-severe fatty liver disease group had a significant increase in FibroScan CAP compared with the non-fatty liver disease group and the mild fatty liver disease group (all P < 0.05), and the mild fatty liver disease group had a significant increase in FibroScan CAP compared with the non-fatty liver disease group ( P < 0.05). In the diagnosis of mild fatty liver disease, MRI-PDFF HFF had an AUC of 0.901 ( P < 0.001), a sensitivity of 90.9%, and a specificity of 82.7% at the optimal cut-off value of 5.1%, and in the diagnosis of moderate-to-severe fatty liver disease, MRI-PDFF HFF had an AUC of 0.972 ( P < 0.001), a sensitivity of 96.1%, and a specificity of 89.5% at the optimal cut-off value of 9.7%. In the diagnosis of mild fatty liver disease, FibroScan CAP had an AUC of 0.829 ( P < 0.001), a sensitivity of 77.3%, and a specificity of 78.8% at the optimal cut-off value of 258.5 dB/m, and in the diagnosis of moderate-to-severe fatty liver disease, FibroScan CAP had an AUC of 0.830 ( P < 0.001), a sensitivity of 76.6%, and a specificity of 78.9% at the optimal cut-off value of 285.5 dB/m. Conclusion Both MRI-PDFF and FibroScan can objectively evaluate the degree of fatty liver disease in patients with CHB. MRI-PDFF HFF and FibroScan CAP can be used as noninvasive markers for the quantitative analysis of CHB with hepatic steatosis, and MRI-PDFF HFF tends to have higher diagnostic efficiency.

ABSTRACT

Novel coronavirus (2019-nCoV) is the pathogen of COVID-19. Some severe cases may suffer from respiratory failure or even death, which poses a great challenge to global public health. 2019-nCoV proteins not only participate in virus proliferation, but also play an important role in antagonizing host innate immune response, especially interferon response. In this paper, 2019-nCoV proteins involved in regulating host interferon response and the complex interaction between 2019-nCoV and interferons were summarized, aiming to provide a theoretical reference for the prevention and control of COVID-19.

ABSTRACT

Objective:To establish a competing risk model to predict the cumulative hazard risk probability of the outcomes (unhealed or hyperthyroidism recurrence) of Graves disease (GD) treated with 131I. Methods:From January 2020 to May 2021, 61 GD patients (13 males, 48 females; age (46.0±13.8) years) who received 131I treatment in Zhangzhou Affiliated Hospital of Fujian Medical University were enrolled. The outcomes of treatment were recovery, unhealed or hyperthyroidism recurrence (event 1), and hypothyroidism (event 2). Follow-up was started 1 month after 131I treatment and ended 1 year later. It was terminated in the following conditions: one of the two events occurred; no event occurred after 1 year of follow-up; the research deadline was up. The Fine-Gray test was used to analyze the factors related to event 1, and then the competitive risk model was established. Results:Thirty-nine patients had hypothyroidism, 17 patients were unhealed or had hyperthyroidism recurrence, 2 patients lost follow-up, and 3 patients had normal thyroid function after 1 year follow-up. Multivariate analysis showed that effective half-life (hazard ratio ( HR)=1.74, 95% CI: 1.10-2.75, β=0.55, P=0.019) and thyroid volume ( HR=1.12, 95% CI: 1.07-1.17, β=1.12, P<0.001) were risk factors for event 1, while the elasticity of thyroid was a protective factor ( HR=0.17, 95% CI: 0.06-0.54, β=-1.76, P=0.003). The C index of the nomogram constructed based on the multi-factor competitive risk model was 0.784(95% CI: 0.633-0.935). Conclusions:Thyroid volume, elastic value, and effective half-life are associated with treatment outcomes of 131I. The competitive risk model can predict the therapeutic outcomes of GD patients treated with 131I.

ABSTRACT

Objective To investigate the correlation between gene polymorphism within human β defensin 1 (DEFB1) and fungal susceptibility to severe sepsis through case-control association study.Methods A total of211 patients with severe sepsis in ICU were enrolled in the present case control study. Sepsis in this study was diagnosed according to the definition of American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference in 1992 and 2002. Based on the development of fungal infection during ICU stay, all 211 patients were divided into fungal infection group (Group Ⅰ) and control group (Group C). Alleles and genotypes of-1816A/G, -390A/T, -52A/G, -44C/G and-20A/G within DEFB1 gene were assayed in all 211 patients by means of DNA direct sequencing, Allele-specific PCR amplifications or high-throughput site-specific TaqMan assay. Genetic analysis was employed to calculate the distribution frequency of haplotypes. The correlation between the genomic variations (allele,genotype and haplotype) and fungal infection was analyzed by Chi-square test or Fisher's exact test.Odds ratio (OR) was employed to reflect the correlation degree of genetic factor with fungal susceptibility to severe sepsis. Results Group Ⅰ enrolled 80 patients, of whom 43 pstients were male, at age of (60.81 ± 18.30) years. Group C enrolled 131 patients, of whom 80 patients were male, at mean age of (60.42 ± 17.03) years. No significant difference was found between two groups in aspect of gender and age (P>0.05). The genetic locus of -1816A/G, -390A/T, -52A/G, -44C/G and -20A/G of both groups were in agreement with Hardy Weinberg equilibrium. No significant difference was found between two groups in the distribution of allelic frequencies and genotype frequencies (P >0.05). No significant difference was found in the distribution frequency of four common haplotypes of the above five genetic locus such as AAACG, ATGCA, GTGGG and ATACG (all P > 0.05). Conclusions Genetic locus of -1816A/G, -390A/T, -52A/G, -44C/G and-20A/G within DEFB1 gene have no correction with fungal infections in severe sepsis, suggesting that DEFB1 gene polymorphism may not serve as a key genetic marker for the predisposition to fungal infection in severe sepsis.

ABSTRACT

Objective: Our aim was to study whether the cellular bronchoalveolar lavage fluid (BALF) profile was associated with the parameters of pulmonary function tests. Methods:Lung function tests and BAL were carried out in 18 untreated, non-smoking patients suffering from sarcoidosis and 18 normal subjects. Results:(1)Lung function tests were normal at rest in patients with sarcoidosis(P>0.05), the single breath carbon monoxide diffusing capacity decreased (P<0.05),and the small airway function decreased too (P<0.05).(2)The percentage of lymphocytes in BALF of sarcoidosis increased comparing with the normal subjects(P<0.01),and the ratio of CD+4 to CD+8 in BALF increased significantly in sarcoidosis(P <0.05), furthermore, the increase of both the percentage of lymphocytes and the ratio of CD+4 to CD+8 in BALF of sarcoidosis were well nagatively correlated with the decrease of the percentage of DLCO (r=-0.67, P<0.01 and r=-0.55, P<0.05, respectively), the decrease of mid-expiratory flow at 50% of vital capacity (FEF50%) was well correlated with the increase of the percentage of lymphocytes in BALF of sarcoidosis (r=-0.54, P<0.05). Conclusion:Pulmonary diffusing capacity(DLCO) was significently correlated with BALF lymphocyte phenotype,so was small airway function,and can act as the marker of activity of sarcoidosis.
