Clinical characteristics of liver function injury in patients with coronavirus disease 2019 / 中华传染病杂志

Objective:To investigate the incidence of liver injury in patients with coronavirus disease 2019 (COVID-19), and to explore its impact on the condition and prognosis of patients.Methods:The medical records of 67 patients with COVID-19 who presented with pneumonia hospitalized at Tongji Hospital, Huazhong University of Science and Technology from February 11 to March 28, 2020 were collected. The results of liver biochemistry and coagulation function test at admission were analyzed. Data were compared by chi-square test, analysis of variance or Kruskal-Wallis H test. Results:Among 67 patients, total bilirubin increased in seven (10.4%) patients, which was slightly abnormal, albumin decreased in 36(53.7%) cases, and was below 30 g/L in 15(22.4%) cases, alanine transaminase (ALT) and aspartate transaminase (AST) were elevated in 19(28.4%) and 12(17.9%) cases, respectively. A total of 22(32.8%) cases had elevated ALT and (or) AST. The incidences with elevated ALT and (or) AST in moderate and severe patients were 33.3%(10/30) and 26.9%(7/26), respectively. Five of 11 critical patients had elevated ALT and (or) AST. There was no significant difference among the three groups ( χ2=1.21, P=0.546). Abnormal alkaline phosphatase and (or) γ-glutamyl transpeptidase were observed in 11(16.4%) cases. The prolongation of prothrombin time (PT) and activated partial thromboplastin time (APTT) occurred in 10(14.9%) and 17(25.4%) patients, respectively, while most of them were slightly abnormal. Only one patient presented with prolongation of PT and APTT meeting the standard of liver failure. A total of 61.2%(41/67) and 65.7%(44/67) of cases showed increase of fibrinogen and D-dimer, respectively, and 28.4%(19/67) and 19.4%(13/67), respectively increased to an obvious extent. The albumin levels in moderate, severe and critical patients were (37.85±6.19) g/L, (32.96±4.33) g/L and (33.02±3.63) g/L, respectively, which were significantly different ( F=7.36, P=0.001). There were significant differences in PT, APTT, fibrinogen and D-dimer among the three groups ( F=3.22, 3.31, 4.06 and H=17.63, respectively, all P<0.05). Conclusions:COVID-19 only leads to mild liver injury and has only mild impact on liver function. The decrease of albumin level and the increase of fibrinogen and D-dimer may be early predicting indexes for the disease severity.

Differential expression of oxidative reductases in different subsets of mouse hematopoietic cells / 中国实验血液学杂志

Hematopoietic stem cells (HSC) are the source of all blood cells, which can differentiate into various hematopoietic hierarchy cells. Physiological level of reactive oxygen species (ROS) plays an important role in regulating functions of HSC as excessive ROS is harmful to HSC. Oxidative reductases and antioxidants can eliminate cellular ROS to maintain ROS homeostasis and thus avoid excessive ROS-caused damages. There are several types of oxidative reductases in cells such as catalase, manganese superoxide dismutase (MnSOD), glutathione peroxidase 1 (GPX1), thioredoxin reductase 1 (Txrnd1) and Nqo1 [NAD(P)H dehydrogenase quinone 1]. However, the functional roles of various oxidative reductases in regulating ROS level in hematopoietic cells remain unclear. This study was to investigate the expression patterns of these oxidative reductases in mouse hematopoietic cells that were sorted out via flow cytometry and to find out important oxidative reductases involving in HSC ROS regulation. The expression of various oxidative reductases was detected by semi-quantitative real-time PCR. The results showed that the expression level of catalase in T cell population was 0.14 times that in LT-HSC population (P < 0.05). The expression levels of MnSOD in CLP population and myeloid cells were 0.56 and 0.47 times that in LT-HSC population respectively (P < 0.05). The expression levels of GPX1 in ST-HSC, GMP, Myeloid cells, MEP, T lymphocytes and B lymphocytes were 1.79, 2.96, 2.07, 0.58, 0.10, 0.6 times that in LT-HSC population respectively (P < 0.05). The expression levels of Txrnd1 in ST-HSC, MPP, CMP, GMP, Myeloid cells, T lymphocytes and B lymphocytes were 3.36, 3.18, 4.19, 6.39, 4.27, 0.016, 0.56 time that in LT-HSC population, respectively (P < 0.05). The expression levels of Nqo1 in ST-HSC, MPP, CMP, GMP, CLP and B cell were 0.30, 0.17, 0.25, 0.10, 0.04, 0.01 times that in LT-HSC population, respectively (P < 0.05). It is concluded that the expression levels of oxidative reductases (catalase, MnSOD, GPX1, Txrnd1 and Nqo1) in hematopoietic hierarchy cells are cell-type specific. It suggests that reductases may play divergent roles in various hematopoietic cell populations. More importantly, the expression level of Nqo1 in LT-HSC population significantly increased as compared with other cell populations, thereby suggesting its unique regulatory role in HSC.
