Abstract
A 65-year-old male patient was admitted for recurrent lymph node enlargement for 5 years and elevated creatinine for 6 months. This patient was diagnosed with angioimmunoblastic T-cell lymphoma 5 years ago and underwent multiple lines of anti-tumor therapy, including cytotoxic chemotherapy; epigenetic modifying drugs such as chidamide and azacitidine; the immunomodulator lenalidomide; and targeted therapy such as rituximab, a CD20-targeting antibody, and brentuximab vedotin, which targets CD30. Although the tumor was considered stable, multiple virus activation (including BK virus, JC virus, and cytomegalovirus) accompanied by the corresponding organ damage (polyomavirus nephropathy, cytomegalovirus retinitis, and progressive multifocal leukoencephalopathy) occurred during anti-tumor treatment. Anti-tumor therapy was suspended and ganciclovir was used. The serum viral load decreased and organ functions were stabilized. The purpose of this report was to raise clinicians' awareness of opportunistic virus reactivation during anti-tumor treatment.

Abstract
The itch-scratching cycle is mediated by neural dynamics in the brain. However, our understanding of the neural dynamics during this cycle remains limited. In this study, we examine the neural dynamics of 126 mouse brain areas by measuring the calcium signal using fiber photometry. We present numerous response patterns in the mouse brain during the itch-scratching cycle. Interestingly, we find that a group of brain areas exhibit activation only at the end of histamine-induced scratching behavior. Additionally, several brain areas exhibit transient activation at the onset of scratching induced by chloroquine. Both histamine- and chloroquine-induced itch evoke diverse response patterns across the mouse brain. In summary, our study provides a comprehensive dataset for the diverse activity pattern of mouse brain during the itch-scratching cycle, paving the way for further exploration into the neural mechanisms underlying the itch-scratching cycle.

Abstract
Objective: To evaluate the predictive value of neutrophil-lymphocyte ratio (NLR) on admission and before discharge for long-term all-cause death (ACD) in patients hospitalized with heart failure with reduced ejection fraction (HFrEF). Methods: Patients hospitalized and discharged from hospital alive with the clinical diagnosis of HFrEF in cardiac care unit (CCU) of TEDA International Cardiovascular Hospital from January 2013 to December 2017 were consecutively enrolled. NLR, which was defined as neutrophil counts divided by lymphocyte counts, was measured 1 day within admission and 3 days before discharge to evaluate the prognostic value of admission NLR in combination with discharge NLR for the ACD after discharge by using of multivariate Cox regression analysis. Patients were followed-up until December 2020 or ACD. Results: A total of 368 patients hospitalized with HFrEF were enrolled with an age of (54±14) years, including 79 females (21.5%). During the median (inter-quartile range, IQR) duration of follow-up after discharge of 30 (10, 60) months, 95 patients died, thus, the rate of ACD was 25.8%. Multivariate Cox regression analysis showed that the NLR level before discharge was an independent predictor of ACD after discharge [hazard ratio (HR)=1.143, 95% confidence interval (CI) 1.048-1.248, P=0.003] after adjusting for other parameters such as systolic blood pressure on admission and at discharge, left ventricular end-diastolic diameter on admission, and usage of aldosterone receptor blockers at discharge. Moreover, compared to those with NLR level at admission ≤2.25 and ≤2.00 before discharge, the long-term risk of ACD after discharge was nearly doubled for patients with NLR level at admission>2.25 and>2.00 before discharge (adjusted HR=1.968, 95%CI 1.198-3.234, P=0.008). Conclusions: The NLR level before discharge was an independent predictor of ACD after discharge for patients hospitalized with HFrEF. Combining NLR levels at admission and before discharge help to better predictive the risk of long-term ACD after discharge.

Abstract
Objective: To investigate the effect of antibiotics application in perioperative period on carotid artery and serum interluekin-6 (IL-6) in chronic periodontitis (CP) rats with hyperlipidemia (HL) or diabetes mellitus (DM). Methods: The models of CP rats with HL or DM were established in different batches. The rats were divided into groups as follows: A and A' were normal control groups, n=7 in each group; B(HL) and B'(DM) were groups of HL and DM, n=7 in each; C(HL+CP) and C'(DM+CP) were groups of CP with HL and CP with DM, n=21 in each. After the establishment of the models, groups C and C' were divided into C1 and C1' non-intervention group, C2 and C2' simple tooth extraction group and C3 and C3' antibiotic-assisted tooth extraction, with 7 rats in each of the groups. Two time interventions were performed to extract experimental teeth (bilateral maxillary first and second molars) in groups C2, C2', C3 and C3'. Serum samples were collected at 5 time points before and after tooth extraction (T1: before the first tooth extraction; T2: one week after the first tooth extraction; T3, T4, T5: the first, third and fifth week after the second tooth extraction), respectively. The absolute content of IL-6 in serum was detected by enzyme-linked immunosorbent assay (ELISA). Ratio of the absolute content in the experimental groups and control groups were calculated as the relative content of IL-6. At the end of the experiments, all rats were euthanasia and the bifurcation vascular tissues of carotid artery were collected for the observation of the carotid artery pathology and plaque formation and the measurement of the thickness of carotid intimal-medial layer (IMT). Results: Carotid artery pathology observation showed the IMT in group C was significantly thickened and the group C2 was the most thickened one (compared with group A, P<0.01). Elastic fibers in groups C1 and C2 were disordered or even broken and disappeared, presenting typical atherosclerotic plaques, which were diffuse calcium salt deposits in the intimal-medial layers and protrude into the lumen. Elastic fibers in group C3 were ranged in ordered relatively without obvious fracture and the number of plaques was significantly reduced. The vascular walls in rats of groups B' and C' were incomplete, the IMTs had no obvious changes, elastic fibers were ranged disorderly and broken and the smooth muscle cells had vacuolar changes. In group C2', the vascular wall was significantly thinned and calcified plaques appeared in the artery, which showed multiple calcification lesions penetrating through the intimal-medial layer or even the whole layer. The vascular wall of group C3' was integrity and the elastic fibers arranged relatively clutter-free, the number of plaques was reduced. Results of detections of IL-6 showed the relative contents of IL-6 in groups B, B', C1, and C1' increased with time. At T3 time point, the relative contents of IL-6 in groups C2 and C3 reached the peak, C2 was 10.4 times of group A and C3 was 9.5 times of group A, and then decreased to different low levels. At T5 point, comparisons of the relative contents of IL-6 showed C3 < C2 < C1 (3.2 times, 5.4 times, 9.6 times of group A, respectively). The relative contents of IL-6 in groups C2' and C3' reached the peak at T2 point (4.9 times and 4.5 times of group A, respectively), and then decline with time. At T5 point, comparisons of the relative contents of IL-6 showed C3'< C2'< C1' (1.2 times, 1.4 times and 3.1 times of group A, respectively). Conclusions: Blood vessels were observed more obvious thickened in the tooth extraction without antibiotic of HL+CP rats with calcifications increase. Blood vessels of DM+CP rats became thin and fragile and even the integrity was damaged. Perioperative use of antibiotics might reduce the carotid artery lesions and decrease serum levels of inflammatory cytokines.

Abstract
OBJECTIVE Aging and oxidative stress may lead to enhanced cellular damage and programmed cell death. To study the association of intrinsic apoptosis with age and the effect of antioxidant supplementation on intrinsic and UV-induced apoptosis in children, young and elderly people. METHODS The study was a 2 months, double-blind, randomized trial. Three age groups were studied: children, young adults and elderly people. A total of 274 healthy subjects were allocated to a group supplemented with moderate amounts of retinol, β-carotene, α-tocopherol, ascorbic acid and selenium or placebo. Plasma oxidative stress parameters were detected and apoptosis of lymphocytes was evaluated with TUNEL staining. RESULTS At baseline, percentages of intrinsic apoptosis were 13.8% and 11.1% in elderly and young people, respectively, both significantly higher than children (6.3%). A decrease of 1.7% and 2.3% in intrinsic apoptosis of lymphocytes was found in the supplemented groups of young and elderly people compared with their control groups (all p values <0.001), but no significant decrease in children. Moreover, percentages UV-induced apoptosis significantly decreased by 1.4%, 1.9% and 3.1% in children, young and elderly people, respectively, compared with control groups after the trial. There were considerable increments in concentrations of plasma β-carotene, retinol, tocopherol, ascorbic acid and selenium in all three treated groups after the supplementation. CONCLUSIONS Young and elderly people have a higher intrinsic apoptosis than children, which was improved by antioxidant supplementation. UV-induced damage was attenuated by the supplementation in all three age groups.
