Surgical treatment is the most effective method to improve the prognosis of type A acute aortic dissection (TAAAD) patients. Thus, this investigation aimed to evaluate the value of postoperative ...platelet to mean platelet volume ratio (PMR) in predicting in-hospital mortality in postoperative TAAAD patients and to compare it with preoperative PMR.A retrospective study (171 postoperative patients) was conducted in the hospital from January 2017 to December 2019. Clinical (age, gender, and outcome of the patients' in-hospital mortality), preoperative PMR, and postoperative laboratory results were gathered. The area under the receiver operating characteristic curve (AUC) and logistic regression were employed.Preoperative and postoperative PMR levels were higher in the survivors than in the nonsurvivors (13.44 ± 7.15 versus 9.15 ± 4.05, P = 0.002; 12.02 ± 6.79 versus 6.85 ± 2.42, P < 0.001; respectively). Multivariate logistic regression indicated that postoperative PMR was an independent factor even adjusted with different variables. Moreover, postoperative PMR had the highest area under the receiver operating characteristic curve (AUC) (AUC: 0.778, 95% CI: 0.708-0.838, P < 0.001), with the best prognostic accuracy, followed by preoperative PMR (AUC: 0.721, 95% CI: 0.648-0.787, P < 0.001). The best cutoff value for postoperative PMR was 9.9206, with a high sensitivity (90.3%) and specificity (55.7%).Postoperative PMR should serve as an independent index to predict in-hospital mortality in TAAAD patients. In addition, postoperative PMR are superior to preoperative PMR to recognize high-risk patients.
Background. The prognosis of Infective endocarditis (IE) is poor, and we conducted this investigation to evaluate the worth of admission lymphocyte-to-white blood cell ratio (LWR) for prediction of ...short-term outcome in IE patients. Methods. We retrospectively assessed the medical records of 147 IE patients from January 2017 to December 2019. Patients were divided into the survivor group and nonsurvivor group. Univariate and multivariate analyses were applied to estimate the independent factors contribution to in-hospital death, and receiver-operator characteristic (ROC) curve was utilized to check the performance. Results. The levels of LWR (0.17 ± 0.08 vs. 0.10 ± 0.06) were significantly increased among the survivor group compared with the nonsurvivor group (P = 0.001). Multivariate analysis displayed that LWR (hazard ratio (HR): 1.755, 1.304–2.362, P < 0.001) was not interfered by other confounding factors for early death. Moreover, ROC analysis suggested that LWR (cutoff value = 0.10) performed the best among assessed indexes for the forecast of primary outcome (area under curve (AUC) = 0.750, 95% confidence interval (CI) = 0.634–0.867, P < 0.001, sensitivity = 70.0%, specificity = 76.4%), and the proportion of in-hospital mortality was remarkably inferior in patients with LWR > 0.10 than in those with LWR ≤ 0.10. (5.83% vs. 31.8%, P < 0.001). Conclusions. LMR is an independent, simple, universal, inexpensive, and reliable prognostic parameter to identify high-risk IE patients for in-hospital mortality.
Alpha-pinene is one of the main defensive components in conifers.
(Coleoptera: Cerambycidae), a wood borer feeding on Pinaceae plants, relies on its detoxifying enzymes to resist the defensive ...terpenoids. Here, we assayed the peroxide level and GST activity of
larvae treated with different concentrations of α-pinene. Meanwhile, a
gene (
) was isolated and analyzed. We determined its expression level and verified its function. The results showed that α-pinene treatment led to membrane lipid peroxidation and thus increased the GST activity. Expression of
was significantly upregulated in guts following exposure to α-pinene, which has a similar pattern with the malonaldehyde level. In vitro expression and disk diffusion assay showed that the MaGSTe3 protein had high antioxidant capacity. However, RNAi treatment of MaGSTe3 did not reduce the hydrogen peroxide and malonaldehyde levels, while GST activity was significantly reduced. These results suggested MaGSTe3 takes part in α-pinene adaptation, but it does not play a great role in the resistance of
larvae to α-pinene.
Atherosclerosis-associated cardiovascular diseases are main causes leading to high mortality worldwide. Macrophage-derived foam cell formation via uptaking modified lipoproteins is the initial and ...core step in the process of atherosclerosis. Meanwhile, scavenger receptor is indispensable for the formation of foam cells. UCHL1, a deubiquitinase, has been widely studied in multiple cancers. UCHL1 could be an oncogene or a tumor suppressor in dependent of tumor types. It remains unknown whether UCHL1 influences cellular oxLDL uptake. Herein we show that UCHL1 deletion significantly inhibits lipid accumulation and foam cell formation. Subsequently, we found that UCHL1 inhibitor or siRNA downregulates the expression of CD36 protein whereas SR-A, ABCA1, ABCG1, Lox-1, and SR-B1 have no significant change. Furthermore, the treatment of UCHL1 inhibition increases the abundance of K48-polyubiquitin on CD36 and the suppression of lipid uptake induced by UCHL1 deficiency is attenuated by blocking CD36 activation. Our study concluded that UCHL1 deletion decreases foam cell formation by promoting the degradation of CD36 protein, indicating UCHL1 may be a potential target for atherosclerosis treatment.

Hepatocellular carcinoma (HCC) remains a medical challenge due to its high proliferation and metastasis. Although deubiquitinating enzymes (DUBs) play a key role in regulating protein degradation, ...their pathological roles in HCC have not been fully elucidated.
By using biomass spectrometry, co-immunoprecipitation, western blotting and immunofluorescence assays, we identify ribosomal protein S16 (RPS16) as a key substrate of ubiquitin-specific peptidase 1 (USP1). The role of USP1-RPS16 axis in the progression of HCC was evaluated in cell cultures, in xenograft mouse models, and in clinical observations.
We show that USP1 interacts with RPS16. The depletion of USP1 increases the level of K48-linked ubiquitinated-RPS16, leading to proteasome-dependent RPS16 degradation. In contrast, overexpression of USP1-WT instead of USP1-C90A (DUB inactivation mutant) reduces the level of K48-linked ubiquitinated RPS16, thereby stabilizing RPS16. Consequently, USP1 depletion mimics RPS16 deficiency with respect to the inhibition of growth and metastasis, whereas transfection-enforced re-expression of RPS16 restores oncogenic-like activity in USP1-deficient HCC cells. Importantly, the high expression of USP1 and RPS16 in liver tissue is a prognostic factor for poor survival of HCC patients.
These findings reveal a previously unrecognized role for the activation of USP1-RPS16 pathway in driving HCC, which may be further developed as a novel strategy for cancer treatment.
Ginseng peptide (GP) (100, 200, 400 mg/kg bw) lowered blood glucose levels, explored the relationship between GP and gut microbiota-based hypoglycemic effects. GP significantly reduced fasting blood ...glucose levels (25.38–13.37 mM), improved insulin resistance (IR) (9.78–5.02), considerably increased liver glycogen content (64.71–97.95 mg/g), glycolytic and gluconeogenesis enzyme activities in T2DM mice, significantly reduced free fatty acids (1.65–0.93 mM), triglycerides (1.55–0.66 mM), total cholesterol (14.75–5.43 mM), and low-density lipoprotein (4.12–2.36 mM) in the serum, significantly increased high-density lipoprotein levels (6.20–17.44 mM) to improve lipid metabolism disorders. According to colonic 16S rDNA sequencing results, GP-H regulated gut microbiota disorders and short chain fatty acid metabolism. Western blot analysis showed that GP could regulate glycogen synthesis, gluconeogenesis, and glucose transport by activating IRS-1/PI3K/Akt and AMPK signaling pathways and improve IR by inhibiting the mitochondrial apoptosis signaling pathway.
Background:
Type A acute aortic dissection (TAAAD) is a destructive cardiovascular disease, with high morbidity and mortality rates. Identifying the high-risk TAAAD patients at an early stage is ...urgently necessary.
Methods:
A retrospective study of 160 patients was carried out. The admission data were retrospectively gathered. Logistic regression analysis and receiver operator characteristic curve (AUC) was utilized.
Results:
Compared with the survivor group, the nonsurvivor group was older, had higher D-dimer levels, red blood cell distribution width (RDW) levels and platelet distribution width (PDW) levels, and lower fibrinogen levels, platelet levels and plateletcrit levels. Multivariate analysis displayed that four independent factors, age (hazard ratio (HR): 7.877, 95% confidence interval (CI) 2.740–22.641, p < 0.001), D-dimer (HR: 3.791, 95% CI 1.520–9.452, p = 0.004), RDW (HR: 3.300, 95% CI 1.109–9.825, p = 0.032), PDW (HR: 3.755, 95% CI 1.436–9.815, p = 0.007) were incorporated into the model. The predict accuracy of the model (AUC 0.861, 95% CI 0.798–0.911, p < 0.001) was best.
Conclusions:
Age, D-dimer, RDW and PDW are independent markers of in-hospital death in TAAAD patients and the newly established model has better performance in predicting high-risk patients. This model can be used as a quick screening tool to assess the prognosis of patients in individualizing.
Neonatal sepsis is one of the leading causes of neonatal death. The aim of this study was to evaluate the value of neutrophil - to - monocyte ratio (NMR) in predicting mortality in neonatal sepsis.
...In this present retrospective study, a total of 134 neonates with sepsis were included. Baseline laboratory parameters were collected. The best cutoff value of NMR was determined by receiver operating characteristic (ROC) curve. Univariate and multivariate analysis were carried out to survey the predict value of NMR.
The results showed that NMR in non-survival group was significantly higher than that in survival group. Results from multivariate analysis showed that high NMR was an independent risk factor for neonatal sepsis (Hazard ratio (HR): 7.519, p = 0.001). ROC displayed that the area under curve (AUC) of NMR was 0.740, sensitivity and specificity of NMR were 80% and 65.8% when 7.65 was selected.
NMR could be a promising prognostic factor for neonatal sepsis.
