Objective:To study the expression of peripheral blood NKT-like cells in patients with systemic sclerosis (SSc), to explore the correlation between NKT-like cells and laboratory and clinical indicators of systemic sclerosis, and investigate the role of NKT-like cells in the occurrence and development of Systemic sclerosis.Methods:Forty-six SSc patients (SSc group) were enrolled from Department of Rheumatology and Immunology of Peking University People 's Hospital during December 2018 to December 2019. Thirty healthy subjects with matched age and sex were selected as healthy control group (HC group). The cell count and percentage of NKT-like cells and other lymphocyte subsets in peripheral blood were detected by flow cytometry. At the same time, other laboratory indexes were determined by different methods. Spearman's correlation analysis, Pearson's correlation analysis, Man-Whitney U test and Fisher's exact test were used to analyze the difference and correlation between NKT-like cells and other clinical and laboratory indicators. Results:Compared with HC group [165(72, 226)cells/μl], the cell count of NKT-like cells in peripheral blood of SSc group[30(19, 58)cells/μl] was significantly decreased ( Z=-5.69, P<0.001). Correlation analysis showed that the cell count of NKT-like cells was positively correlated with total T lymphocytes ( r=0.56, P<0.001), CD4 +T cells ( r=0.42, P=0.004), CD8 +T cells ( r=0.60, P<0.001), B cells ( r=0.50, P<0.001) and NK cells ( r=0.33, P=0.024), respectively. The percentage of NKT-like cells in lymphocytes was also positively correlated with the percentage of CD8 +T cells ( r=0.34, P=0.020), but not significantly correlated with other subset of lymphocytes. The ESR of the NKT-like cell decreased group was significantly higher than that of the NKT-like normal group[15(9, 28) mm/1 h vs 8 (4, 16) mm/1 h, Z=-2.04, P=0.042]. Moreover, the cell count of NKT-like cells was negatively correlated with ESR ( r=-0.34, P=0.019). Conclusion:The cell count and percentage of NKT-like cells in peripheral blood of SSc patients decreased significantly. NKT-like cells were not only positively correlated with a variety of lymphocyte subpopulations, but also negatively correlated with ESR. NKT-like cells may be used as an indicator to monitor the disease activity in patients with SSc.

Objective:To compare the curative effects of different venous cannulas and drainage to improve patient's whole body oxygenation during the auxiliary process of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in lung transplantation.Methods:From December 2016 to December 2019, 12 patients who were assisted by VA-ECMO in one lung transplantation in People's Hospital of Henan Province were selected as the research objects. According to the number of side holes of venous cannulas, they were divided into two groups: one group with few side holes and other group with multiple side holes. The differences in blood gas indexes among the right radial artery, left radial artery, and right internal jugular vein before and after assistance were compared, and the assistance effect was evaluated.Results:The arterial partial pressure of oxygen (PaO 2) of blood gas indexes of the right and left radial arteries in both groups were significantly higher than that before assistance [mmHg (1 mmHg = 0.133 kPa): right and left radial artery in few side holes group: 79.5±4.2 vs. 48.3±3.8 and 88.1±3.5 vs. 48.3±3.8; right and left radial artery in multiple side holes group: 67.7±5.9 vs. 48.7±3.2 and 84.0±3.8 vs. 48.7±3.2, all P < 0.05]. The arterial partial pressure of carbon dioxide (PaCO 2) of blood gas index was significantly lower than that before assistance (mmHg: 44.2±2.6 vs. 71.7±4.4 for the right radial artery and 44.7±1.4 vs. 71.7±4.4 for the left radial artery in the group with few side holes; 46.2±2.1 vs. 71.2±3.5 for the right radial artery and 44.1±1.9 vs. 71.2±3.5 for the left radial artery in the group with multiple side holes, all P < 0.05). The partial pressure of oxygen in venous blood (PvO 2) of blood gas index of ECMO system in the group with few side holes was significantly lower than that of the multiport side holes group (mmHg: 56.4±3.2 vs. 88.7±1.5, P < 0.01), and the partial pressure of carbon dioxide in venous blood (PvCO 2) was significantly higher than that of multiport side holes group (mmHg: 63.6±3.7 vs. 44.2±1.7, P < 0.01). Conclusions:When VA-ECMO is used in lung transplantation, the superior vena cava blood flow can be fully drained by using intravenous cannula with few side holes. It can effectively improve the oxygenation of the upper body of lung transplant patients, avoid the dilemma of hypoxemia in the upper body and hyperxemia in the lower body, provide more effective assistance to patients undergoing single lung transplantation, and is more meaningful for improving the oxygenation status of the whole body in patients undergoing single lung transplantation.

BACKGROUND:
Human neutrophil lipocalin (HNL) has been used extensively to differentiate acute bacterial infection from febrile diseases as a biomarker to reflect the activation of the neutrophil. The serum HNL levels in the adult-onset Still's disease (AOSD) patients with and without infection, as well as the healthy controls (HCs), were analyzed statistically in this study to evaluate the value of HNL for the diagnosis of AOSD.
METHODS:
A total of 129 AOSD patients were enrolled, from whom blood samples were drawn and the AOSD diagnosis was confirmed through the review of the medical records, where the systemic score, demographic characteristics, clinical manifestations, and laboratory parameters were also collected for the patients; in addition, a total of 40 HCs were recruited among the blood donors from the healthcare center with the relevant information collected. The HNL test was done for the blood samples with the enzyme-linked immunosorbent assay and the analyses were done for the correlations of HNL with clinical manifestations and diagnostic effectiveness.
RESULTS:
The serum HNL increased significantly in the patients with only AOSD as compared with that in the HCs (139.76 ± 8.99 ng/mL vs . 55.92 ± 6.12 ng/mL; P < 0.001). The serum HNL level was correlated with the white blood cell (WBC) count ( r = 0.335, P < 0.001), neutrophil count ( r = 0.334, P < 0.001), erythrocyte sedimentation rate ( r = 0.241, P = 0.022), C-reactive protein ( r = 0.442, P < 0.0001), and systemic score ( r = 0.343, P < 0.0001) in the AOSD patients significantly. Patients with fever, leukocytosis ≥15,000/mm 3 , and myalgia in the HNL-positive group were observed relatively more than those in the HNL-negative group ( P = 0.009, P = 0.023, and P = 0.007, respectively). HNL was a more sensitive indicator than ferritin and C-reactive protein (CRP) to differentiate the AOSD patients with bacterial infection from AOSD-only patients, and the Youden index was 0.6 for HNL and 0.29 for CRP.
CONCLUSION
Serum HNL can be used as a biomarker for the diagnosis of the AOSD, and HNL is also observed to be associated with the disease activity.
