Abstract
This study aims to explore the impacts of ApoB-100/SORT1-mediated immune microenvironment during acute spinal cord injury (SCI), and to investigate the potential mechanism. CB57BL/6 mice underwent moderate thoracic contusion injury to establish the SCI animal model, and received ApoB-100 lentivirus injection to interfere ApoB-100 level. Functional recovery was assessed using the Basso, Beattie, and Bresnahan (BBB) score and footprint analysis. Transmission electron microscopy was applied to observe the ultrastructure of the injured spinal cord tissue. Hematoxylin-eosin (HE) staining and Perls staining were conducted to assess histological changes and iron deposition. Biochemical factor and cytokines were detected using their commercial kits. M1/M2 macrophage markers were detected by immunofluorescence assay in vivo and by flow cytometry in vitro. HT22 neurons were simulated by lipopolysaccharide (LPS), followed by incubation with polarized macrophage medium to simulate the immune microenvironment of injured spinal cord in vitro. The local immune microenvironment is changed in SCI mice, accompanied with the occurrence of oxidative stress and the elevation of both M1 and M2 macrophages. Knockdown of ApoB-100 ameliorates oxidative stress and lipid disorder, and inhibits inflammation and ferroptosis in SCI mice. Importantly, knockdown of ApoB-100 can partly restrict M1 macrophages but does not change M2 macrophage proportion in SCI mice. Further, M1 macrophages are observed to attenuate the inflammatory response, oxidative stress, and ferroptosis levels of LPS-induced HT22 cells, which is further strengthened by SORT1 knockdown. Blockage of ApoB-100/SORT1-mediated immune microenvironment plays a protective role against SCI via inhibiting oxidative stress, inflammation, lipid disorders, and ferroptosis, providing novel insights of the targeted therapy of SCI.

Abstract
Objective: To investigate the role of the Abdominal Aortic Calcification-8 (AAC-8) scoring system in predicting restenosis or occlusion of lower extremity arteries after dilatation and angioplasty with drug-coated balloon (DCB). Methods: In this retrospective study, 62 patients who underwent dilatation and angioplasty with DCB for lower limb atherosclerotic obliterans (ASO) were enrolled from September 2018 to June 2022 in Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School. Among them who aged (73.9±11.3) years, 37 were males and 25 were females. Patients were divided into two groups according to the condition of the lower extremity arteries after dilatation and angioplasty with DCB: recurrence group (n=26) and patency group (n=36). Logistic regression was used to analyze the factors associated with restenosis or occlusion of lower extremity arteries after dilatation and angioplasty with DCB. The predictive value of the AAC-8 score for restenosis or occlusion of the lower extremity arteries after dilatation and angioplasty with DCB was analyzed using the receiver operating characteristic curves (ROC curves). Results: The postoperative follow-up was 16.30 (10.97, 24.10) months in the patency group and 9.03 (6.98, 15.31) months in the recurrence group. The results of multifactorial logistic regression analysis showed that an elevated AAC-8 score (OR=1.388, 95%CI: 1.067-1.806, P=0.015) was an associated factor of restenosis or occlusion of the lower extremity arteries after dilatation and angioplasty with DCB. The ROC curve analysis showed that the area under the curve (AUC) of the AAC-8 score for predicting restenosis or occlusion of the lower extremity arteries after dilatation and angioplasty with DCB was 0.687 (95%CI: 0.550-0.824, P=0.013), with a cut-off value of 5.5 points, a sensitivity of 65.4% and a specificity of 69.5%. Conclusions: Elevated AAC-8 score is associated with restenosis or occlusion of the lower extremity arteries after dilatation and angioplasty with DCB. When the cut-off value is 5.5, the AAC-8 score predicts restenosis or occlusion of the lower extremity arteries after DCB dilation and angioplasty with a sensitivity of 65.4% and a specificity of 69.5%.

Abstract
Objective: To investigate the study of the correlation between C-reactive protein to albumin ratio (CAR) and restenosis after stenting in patients with lower extremity atherosclerotic occlusive disease(LEASO). Methods: The clinical data of 95 patients with LEASO admitted to the Department of Vascular Surgery of Nanjing Drum Tower Hospital from June 2020 to December 2022 were retrospectively analyzed. There were 67 males and 28 females,aged (73.1±9.4) years (range:51 to 92 years). The patients were classified into the restenosis group (n=61) and the patency group (n=34) according to the CT angiography results. Independent sample t test,Mann-Whitney U test and χ2 test were used to compare the data between two groups. Risk factors for restenosis after femoropopliteal artery stenting in patients with LEASO were analyzed using multivariate Cox regression. The relationship between preoperative CAR level and restenosis after stent placement was analyzed. Subject operating characteristic(ROC) curves of CAR were plotted to assess the predictive value of CAR for restenosis after stenting,and the results were expressed as area under the curve (AUC). Results: The aortoiliac calcification grade,number of stents,length of stents,C-reactive protein and CAR levels in restenosis group were higher than those in the patency group,and the serum albumin level was lower than that in the patency group(all P<0.05). And the results of multifactorial Cox regression analysis showed that higher pre-procedure CAR level and lower ABI value was an independent risk factor for in-stent restenosis. The AUC of the ROC curve for restenosis was 0.737(95%CI:0.617 to 0.856),the AUC of the ROC curve for 12-month restenosis was 0.709(95%CI:0.602 to 0.815), and the AUC of the ROC curve for 24-month restenosis was 0.702(95%CI:0.594 to 0.811). Conclusion: Higher pre-procedural CAR levels in patients with LEASO is risk factor for in-stent restenosis,and CAR has a predictive value for restenosis after lower extremity arterial stent dilatation and angioplasty.

Abstract
The association between the embryo quality, clinical characteristics, miRNAs (secreted by blastocysts in the culture medium) and pregnancy outcomes has been well-established. Studies on prediction models for pregnancy outcome, using clinical characteristics and miRNA expression, are limited. We aimed to establish the prediction model for prediction of pregnancy outcome of woman after a fresh cycle of Day 5 single blastocyst transfer (Day 5 SBT) based on clinical data and miRNA expression. A total of 86 women, 50 with successful pregnancy and 36 with pregnancy failure after fresh cycle of Day 5 SBT, were enrolled in this study. All samples were divided into training set and test set (3:1). Based on clinical index statistics of enrolled population and miRNA expression, the prediction model was constructed, followed by validation of the prediction model. Four clinical indicators, female age, sperm DNA fragmentation index, anti-mullerian hormone, estradiol, can be used as independent predictors of pregnancy failure after fresh cycle of Day 5 SBT. Three miRNAs (hsa-miR-199a-3p, hsa-miR-199a-5p and hsa-miR-99a-5p) had a potential diagnostic value for pregnancy failure after Day 5 SBT. The predictive effect of model combining 4 clinical indicators and 3 miRNAs (area under the receiver operating characteristic curve, AUC = 0.853) was better than models combining single 4 clinical indicators (AUC = 0.755) or 3 miRNAs (AUC = 0.713). Based on 4 clinical indicators and 3 miRNAs, a novel model to predict pregnancy outcome in woman after fresh cycle of Day 5 SBT has been developed and validated. The predictive model may be valuable for clinicians to make the optimal clinical decision and patient selection.

Abstract
BACKGROUND Pancreaticoduodenectomy (PD) is a complex and traumatic abdominal surgery with a high risk of postoperative complications. Nutritional support, including immunonutrition (IMN) with added glutamine, arginine, and ω-3 polyunsaturated fatty acids, can improve patients' prognosis by regulating postoperative inflammatory response. However, the effects of IMN on PD patients' outcomes require further investigation. METHODS PMC, EMbase, web of science databases were used to search literatures related to IMN and PD. Data such as length of hospital stay, infectious complications, non-infectious complications, postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), mortality, systemic inflammatory response syndrome (SIRS) duration, IL-6, and C-reactive protein (CRP) were extracted, and meta-analyses were performed on these data to study their pooled results, heterogeneity, and publication bias. RESULTS This meta-analysis involved 10 studies and a total of 572 patients. The results showed that the use of IMN significantly reduced the length of hospital stay for PD patients (MD = -2.31; 95% CI = -4.43, -0.18; P = 0.03) with low heterogeneity. Additionally, the incidence of infectious complications was significantly reduced (MD = 0.42; 95% CI = 0.18, 1.00, P = 0.05), with low heterogeneity after excluding one study. However, there was no significant impact on non-infectious complications, the incidence of POPF and DGE, mortality rates, duration of SIRS, levels of IL-6 and CRP. CONCLUSION The use of IMN has been shown to significantly shorten hospital stays and decrease the frequency of infectious complications in PD patients. Early implementation of IMN is recommended for those undergoing PD. However, further research is needed to fully assess the impact of IMN on PD patients through larger and higher-quality studies.

Abstract
AIMS Oxygen therapy plays a vital role in the development of bronchopulmonary dysplasia (BPD), which is the independent risk factor for neurodevelopment deficits in premature infants. However, the effect of hippocampal cyclin-dependent kinase 5 (CDK5) on BPD-associated neurodevelopment deficits is not fully understood. METHODS Mice were placed in a hyperoxia chamber from postnatal Day 1 to Day 7. Hematoxylin and eosin staining was used to evaluate the lung histomorphological characteristics. Learning and memory functions of mice were detected by Morris water maze. TUNEL staining was applied to measure the number of apoptotic cells. The expression of CDK5, apoptosis-related protein, and neuroplasticity-related proteins were analyzed by Western blot. Golgi staining was used to assess the structure of dendritic spines. RESULTS Hyperoxia-induced BPD mice showed a long-term learning and memory dysfunction, more severe neuronal apoptosis, and a decline of synaptic plasticity. Inhibition of CDK5 overactivation ameliorated cognitive deficits, neuronal apoptosis, and synaptic plasticity disorders in BPD mice. CONCLUSIONS This study first found a vital role of CDK5 in BPD-associated neurodevelopmental disorders. Inhibition of CDK5 overexpression could effectively improve cognitive dysfunctions in BPD mice, which indicated that hippocampal CDK5 may be a new target for prevention and treatment in learning and memory dysfunction of BPD.

Abstract
Objective: To explore the clinical characteristics and prognostic factors of patients with acute glyphosate poisoning, and to provide reference for the comprehensive treatment and prognosis judgment of acute glyphosate poisoning. Methods: The complete hospitalized medical records data of 40 patients with acute glyphosate poisoning who were treated in the emergency department of Affiliated Hospital of Yangzhou University from 2014 to 2019 were collected in August 2020. According to the outcome during the follow-up period of 90 d after discharge from hospital, patients were divided into survival group (n=33) and treatment failure group (n=7) . The clinical characteristics of the two groups were analyzed. The influencing factors of prognosis were analyzed by binary logistic regression, and the receiver operating characteristic (ROC) curve was used to evaluate the value of white blood cell count level at admission to the prognosis of patients with acute glyphosate poisoning. Results: The average age of the 40 glyphosate poisoning patients was (57.70±19.72) years old, the oral dose was 100 (50, 200) ml, the hospital stay was 4.0 (1.0, 5.0) d, and the fatality rate was 17.5% (7/40) . The main clinical manifestations were the symptoms of the digestive tract, respiratory tract, cardiovascular system and nervous system. Logistic regression showed that white blood cell level at admission was an influencing factor for the prognosis of patients with acute glyphosate poisoning (OR=1.148, 95%CI: 1.124-1.791, P=0.003) . The ROC curve showed that the best diagnostic cut-off value of white blood cell level at admission to the prognosis of acute glyphosate poisoning was 14.65×10(9)/L, the area under the curve (AUC) was 0.9351. The sensitivity was 100.00%, and the specificity was 84.85%. Conclusion: High level of white blood cell at admission is a risk factor for the prognosis of acute glyphosate poisoning, and white blood cell level at admission has a certain predictive value for the prognosis of acute glyphosate poisoning.
