Background Since December 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused an outbreak of corona virus disease 2019 (COVID-19) in Wuhan, China. The Objective of this study was to detect the EBV coinfection in COVID-19.Methods In this retrospective single-center study, we included 67 patients with confirmed COVID-19 in Renmin Hospital of Wuhan University from January 9 to February 29, 2020. Patients were divided into EBV seropositive group and seronegative group according to the serological results of EBV, and the characteristics differences between the two groups were compared.Results 67 COVID-19 patients were included in our study. The median age was 37 years, with 35 (52.2%) females. Among these COVID-19 patients, 37 (55.2%) patients were seropositive for EBV viral capsid antigen (VCA) IgM antibody. EBV seropositive COVID-19 patients had a 3.09-fold risk of having a fever symptom than EBV seronegative (95%CI, 1.11-8.56; P=0.03). C-reactive protein (CRP) (P=0.02) and the aspartate aminotransferase (AST) (P=0.04) in EBV seropositive COVID-19 patients were higher than that in EBV seronegative patients. EB seropositive patients had a higher portion of corticosteroid use than the EB seronegative patients (P=0.03).Conclusions EBV acute infection was found in COVID-19 patients. EBV seropositivity was associated with fever and increased inflammation. EBV reactivation may affected the treatment of COVID-19.

The biomarkers for predicting venous thromboembolic events (VTEs) after oncologic surgery are still lacking. The current study aimed to analyze the relationships of CD62P and GP IIb/IIIa with hypercoagulation after oncologic surgery. A total of 76 patients with primary abdominopelvic tumors in our hospital were enrolled. The patients were divided into groups A (malignancy with no VTE group), B (malignancy with VTE group), and C (benign with no VTE group). Twenty healthy volunteers were selected as control. The plasma CD62P (4.69 ± 2.55 vs. 1.76 ± 0.48) and the GP IIb/IIIa (9.28 ± 3.79 vs. 1.76 ± 0.48) levels in group A were significantly higher than those in the control group preoperatively. The CD62P (31.46 ± 17.13 vs. 13.51 ± 7.43, P < 0.05), GP IIb/IIIa (42.33 ± 21.82 vs. 13.51 ± 7.43, P < 0.05), and D-dimer (7.33 ± 2.34 vs. 2.03 ± 0.55, P < 0.05) levels in group B were markedly higher 7 days after operation compared with those in group A. The CD62P and the GP IIb/IIIa exhibited a positive correlation with the hypercoagulable state after oncologic surgery.

Purpose. To assess the predictive value of in ammatory blood biomarkers in rhegmatogenous retinal detachment (RRD) patients and its correlation with proliferative retinopathy (PVR) grade. Methods. 82 RRD patients and 1 : 1 age-and gender-randomly matched cataract patients as the control group were included. e clinical features and laboratory parameters of all participants were collected and recorded, and the comprehensive index of in ammatory blood and its correlation with PVR were calculated. Results. Monocytes and monocyte-to-high-density lipoprotein ratio (MHR) were signi cantly lower (P 0.005, P 0.044), while mean platelet volume (MPV), lymphocyte-to-monocyte ratio (LMR), and MPV-to-platelet ratio (MPR) were signi cantly higher in RRD patients as compared with the control group (P 0.013, P 0.019, P 0.037). LMR and MPR might be the predictors of RRD. e receiver operating characteristics analysis showed that the values of MPV, LMR, and MPR in RRD patients were 0.612, 0.606, and 0.594, respectively. PVR grade was not associated with in ammatory blood biomarkers. Conclusion. e increase in MPV, LMR, and MPR were associated with increased odds of RRD. LMR and MPR may be useful as inexpensive and e ortless biomarkers for assessing the occurrence of RRD.

Purpose To compare retinal ganglion cell complex (GCC) parameters between rhegmatogenous retinal detachment (RRD) eyes and normal contralateral eyes after vitrectomy and to evaluate their correlation with inflammatory blood markers. Methods We investigated 25 eyes that underwent vitrectomy due to RRD. Venous blood samples were collected from all participants before 08:00 a.m. on the second day of admission after a 12-hour fast for blood counts. The differences of retinal structure between RRD and contralateral eyes were compared 1 week postoperatively. Results Focal loss volume (FLV) (2.009 ± 1.286)% was significantly increased compared with the contralateral eyes (p <  0.001). Monocyte-to-high-density lipoprotein was significantly positively correlated with GCC thickness parameters, and negatively correlated with FLV and global loss volume (GLV). Postoperative best-corrected visual acuity was negatively correlated with GLV (p = 0.039, R2 = 0.172). Conclusion Retinal ganglion cells (RGCs) loss might present early postoperatively in RRD eyes, and was associated with systemic inflammation. RGCs loss might affect postoperative vision.
