Abstract
Myocardial ischemia-reperfusion injury (MIRI) is involved in the pathogenesis of multiple cardiovascular diseases. This study elucidated the biological function of lysine acetyltransferase 5 (KAT5) in cardiomyocyte pyroptosis during MIRI. Oxygen-glucose deprivation/reoxygenation and left anterior descending coronary artery ligation were used to establish MIRI models. Here we show, KAT5 and STIP1 homology and U-box-containing protein 1 (STUB1) were downregulated, while large tumor suppressor kinase 2 (LATS2) was upregulated in MIRI models. KAT5/STUB1 overexpression or LATS2 silencing repressed cardiomyocyte pyroptosis. Mechanistically, KAT5 promoted STUB1 transcription via acetylation modulation, and subsequently caused ubiquitination and degradation of LATS2, which activated YAP/β-catenin pathway. Notably, the inhibitory effect of STUB1 overexpression on cardiomyocyte pyroptosis was abolished by LATS2 overexpression or KAT5 depletion. Our findings suggest that KAT5 overexpression inhibits NLRP3-mediated cardiomyocyte pyroptosis to relieve MIRI through modulation of STUB1/LATS2/YAP/β-catenin axis, providing a potential therapeutic target for MIRI.

Abstract
AIMS Long non-coding RNA (LncRNA) small nucleolar RNA host gene 18 (SNHG18) has been widely implicated in cancers. However, little is known about its functional involvement in vascular diseases. Herein, we attempted to explore a role for SNHG18 in modulating vascular smooth muscle cell (VSMC) contractile phenotype and injury-induced neointima formation. METHODS AND RESULTS Analysis of single cell RNA sequencing and transcriptomic datasets showed decreased levels of SNHG18 in injured and atherosclerotic murine and human arteries, which is positively associated with VSMC contractile genes. SNHG18 was upregulated in VSMCs by TGFβ1 through transcription factors Sp1 and SMAD3. SNHG18 gene gain/loss-of-function studies revealed that VSMC contractile phenotype was positively regulated by SNHG18. Mechanistic studies showed that SNHG18 promotes a contractile VSMC phenotype by up-regulating miR-22-3p. SNHG18 up-regulates miR-22 biogenesis and miR-22-3p production by competitive binding with the A-to-I RNA editing enzyme, adenosine deaminase acting on RNA-2 (ADAR2). Surprisingly, we observed that ADAR2 inhibited miR-22 biogenesis not through increasing A-to-I editing within primary miR-22, but by interfering the binding of microprocessor complex subunit DGCR8 to primary miR-22. Importantly, perivascular SNHG18 overexpression in the injured vessels dramatically up-regulated the expression levels of miR-22-3p and VSMC contractile genes, and prevented injury-induced neointimal hyperplasia. Such modulatory effects were reverted by miR-22-3p inhibition in the injured arteries. Finally, we observed a similar regulator role for SNHG18 in human VSMCs, and a decreased expression level of both SNHG18 and miR-22-3p in diseased human arteries; and we found that the expression level of SNHG18 was positively associated with that of miR-22-3p in both healthy and diseased human arteries. CONCLUSION We demonstrate that SNHG18 is a novel regulator in governing VSMC contractile phenotype and preventing injury-induced neointimal hyperplasia. Our findings have important implications for therapeutic targeting snhg18/miR-22-3p signalling in vascular diseases.

Abstract
BACKGROUND Minimally invasive surgery has emerged as a favorable alternative to conventional surgery for various cardiac conditions. This study aimed to compare the perioperative outcomes and follow-up results of the robotic approach versus the sternotomy approach for left atrial myxoma (LAM) resection. METHOD We retrospectively analyzed the perioperative outcomes and follow-up results of 94 patients who underwent left atrial myxoma resection using either the sternotomy approach (n = 64) or the robotic approach (n = 30) at our center between January 2017 and April 2023. Multiple linear regressions were employed to examine the actual impact of the surgical approach on perioperative outcomes while controlling for potential confounding factors. RESULTS There were no in-hospital deaths or follow-up deaths in the robotic group. Univariate analyses revealed that robotic LAM resection had a longer cardiopulmonary bypass (CPB) time (99.93 ± 22.30 vs. 76.28 ± 24.92, P < 0.001), longer aortic clamping time (57.80 ± 20.27 vs. 47.89 ± 18.10, P = 0.019), reduced postoperative drainage (P < 0.001), shorter mechanical ventilation time (P = 0.005), shorter postoperative bed-stay time (P < 0.001), shorter postoperative hospitalization time (P = 0.040), and higher hospital costs (P = 0.001) compared to the sternotomy group. After adjusting for baseline characteristics in a multiple regression model, a longer CPB time (B = 28.328; CI, 18.609-38.047; P < 0.001), longer aortic clamping time (B = 11.856; CI, 4.069-19.644; P = 0.003), reduced postoperative drainage (B = -200.224; CI, -254.962- -145.486; P < 0.001), shorter mechanical ventilation time (B = -3.429; CI, -6.562- -0.295; P = 0.032), shorter postoperative bed-stay time (B = -2.230; CI, -3.267- -1.193; P < 0.001), shorter postoperative hospitalization time (B = -1.998; CI, -3.747- -0.250; P = 0.026), and higher hospital costs (B = 2096.866, P = 0.002) were found in the robotic group. Furthermore, the robotic group exhibited a faster return to exercise compared to the sternotomy group (Log-Rank χ2 = 34.527, P < 0.001). CONCLUSION Both the robotic and sternotomy approaches are viable and safe options for LAM resection. However, despite the higher costs, longer CPB time, and longer aortic clamping time associated with robotic LAM resection, this technique was correlated with reduced postoperative drainage and faster postoperative recovery compared to the sternotomy technique.

Abstract
OBJECTIVE To investigate the independent risk factors for postoperative prolonged ICU stay in patients with Stanford type A aortic dissection (TAAD) and assess the clinical outcomes of prolonged ICU stay. METHOD The clinical data of 100 patients with TAAD admitted to the Department of Cardiovascular Surgery, First Affiliated Hospital of Anhui Medical University from December 2018 to September 2022 were retrospectively collected and analyzed. Patients were divided into two groups, based on the postoperative ICU stay (7 days as the threshold), regular ICU stay group (< 7 days) and prolonged ICU stay group (≥ 7 days). First, preoperative and intraoperative materials were collected for univariate analysis. Then, the significant variables after univariate analysis were analyzed using logistic regression, and the final independent risk factors for prolonged ICU stay were determined. Meanwhile, the postoperative clinical outcomes were analyzed with the aim of assessing the clinical outcomes due to prolonged ICU stay. RESULTS There were 65 and 35 patients in the regular ICU stay group and the prolonged ICU stay group, respectively. In accordance with the result of univariate analysis in the two groups, emergency surgery (χ2 = 13.598; P < 0.001), preoperative urea nitrogen (t = 3.006; P = 0.004), cardiopulmonary bypass (CPB) time (t = 2.671; P = 0.001) and surgery time (t = 2.630; P = 0.010) were significant. All significant variates were analyzed through logistic regression, and it was found that emergency surgery (OR = 0.192; 95% CI: 0.065-0.561), preoperative urea nitrogen (OR = 0.775; 95% CI: 0.634-0.947) and cardiopulmonary time (OR = 0.988; 95% CI: 0.979-0.998) were independent risk factors for prolonged postoperative ICU stay. The Receiver Operating Characteristic (ROC) curves of these three factors were also effective in predicting postoperative prolonged ICU stay (Emergency surgery, AUC = 0.308, 95% CI: 0.201-0.415; Preoperative urea nitrogen, AUC = 0.288, 95% CI: 0.185-0.392; cardiopulmonary time, AUC = 0.340, 95% CI: 0.223-0.457). Moreover, compared with a single factor, the predictive value of combined factors was more significant (AUC = 0.810, 95% CI: 0.722-0.897). For the comparison of postoperative data in the two groups,, compared with the regular ICU stay group, the incidence of adverse events in the prolonged ICU stay group increased significantly, including limb disability of limbs (χ2 = 22.182; P < 0.001), severe organ injury (χ2 = 23.077; P < 0.001), tracheotomy (χ2 = 17.582; P < 0.001), reintubation (χ2 = 28.020; P < 0.001), 72 h tracheal extubation after surgery (χ2 = 29.335; P < 0.001), 12 h consciousness recovery after surgery (χ2 = 18.445; P < 0.001), ICU re-entering (χ2 = 9.496; P = 0.002) and irregular discharging (χ2 = 24.969; P < 0.001). CONCLUSION Emergency surgery, preoperative urea nitrogen, and CPB time are risk factors for postoperative prolonged ICU stay after TAAD surgery. Furthermore, prolonged ICU stay is associated with worse clinical outcomes. Hence, a reasonable strategy should be adopted proactively focusing on the risk factors to shorten ICU stays and improve clinical outcomes.

Abstract
Calcific aortic valve disease (CAVD) is featured by thickening and calcification of the aortic valve. Osteoblast differentiation is a crucial step in valve calcification. Long non-coding RNAs (LncRNAs) participate in the osteogenic differentiation of mesenchymal cells. However, the character of lncRNA FGD5 antisense RNA 1 (FGD5-AS1) in CAVD is uncertain. After collection of human aortic valve tissue samples, detection of FGD5-AS1, microRNA (miR)-497-5p and Baculovirus inhibitor 5 (BIRC5) was conducted. Valve mesenchymal cells were isolated from CAVD patients and induced to differentiate to osteoblasts, and transfected with FGD5-AS1, miR-497-5p and BIRC5 plasmids. Detection of the alkaline phosphatase activity was after osteogenic induction of human aortic valve interstitial cells (hAVICs); Detection of the degree of calcium nodules and osteoblast differentiation markers (RUNX2 and OPN) was conducted. After establishment of a mouse model of CAVD, detection of the thickness of aortic valve leaflets, and the degree of calcification of the valve leaflets, and evaluation of echocardiographic parameters were implemented. Experimental data manifested in CAVD patients, lncRNAFGD5-AS1 and BIRC5 were reduced, but miR-497-5p was elevated; Enhancing lncRNA FGD5-AS1 or repressing miR-497-5p mitigated CAVD by restraining osteogenic differentiation; LncRNA FGD5-AS1 sponged miR-497-5p to target BIRC5; Repressive BIRC5 turned around the therapeutic action of elevated FGD5-AS1 or depressed miR-497-5p on hAVICs; Enhancive FGD5-AS1 in vivo was available to reduce ApoE-/- mouse CAVD induced via high cholesterol diet. All in all, lncRNAFGD5-AS1 targets BIRC5 via miR-497-5p to alleviate CAVD.

Abstract
BACKGROUND Lung adenocarcinoma (LUAD) is a common cancer with a poor prognosis. Pyroptosis is an important process in the development and progression of LUAD. We analyzed the risk factors affecting the prognosis of patients and constructed a nomogram to predict the overall survival of patients based on different pyroptosis-related genes (PRGs) subtypes. METHODS The genomic data of LUAD were downloaded from the TCGA and GEO databases, and all data were filtered and divided into TCGA and GEO cohorts. The process of data analysis and visualization was performed via R software. The data were classified based on different PRGs subtypes using the K-means clustering method. Then, the differentially expressed genes were identified between two different subtypes, and risk factors analysis, survival analysis, functional enrichment analysis, and immune cells infiltration landscape analysis were conducted. The COX regression analysis was used to construct the prediction model. RESULTS Based on the PRGs of LUAD, the patients were divided into two subtypes. We found the survival probability of patients in subtype 1 is higher than that in subtype 2. The results of the logistics analysis showed that gene risk score was closely associated with the prognosis of LUAD patients. The results of GO analysis and KEGG analysis revealed important biological processes and signaling pathways involved in the differentially expressed proteins between the two subtypes. Then we constructed a prediction model of patients' prognosis based on 13 genes, including IL-1A, P2RX1, GSTM2, ESYT3, ZNF682, KCNF1, STK32A, HHIPL2, GDF10, NDC80, GSTA1, BCL2L10, and CCR2. This model was strongly related to the overall survival (OS) and also reflects the immune status in patients with LUAD. CONCLUSION In our study, we examined LUAD heterogeneity with reference to pyroptosis and found different prognoses between the two subtypes. And a novel prediction model was constructed to predict the OS of LUAD patients based on different PRGs signatures. The model has shown excellent predictive efficiency through validation.

Abstract
Aortic Dissection (AD) is a cardiovascular emergency with high mortality, of which one feature is the phenotypic switch of vascular smooth muscle cells (VSMCs). Transient Receptor Potential Channel Interacting (PKD1) has been regarded as one regulator as well as one biomarker for AD. However, multiple candidate pathways were reported though which PKD1 regulates AD in previous study, a comprehensive insight is still absent. In this study, we compared the AD and normal samples in transcriptome scale, and detected 717 PKD1-related differential expressed genes, which enriched in mitogen-activated protein kinase (MAPK) signal transduction (AD tissue preference) and VSMC contraction pathway (normal tissue preference). Furthermore, we also found two important functional hub genes in PKD1 regulation, JUN and ACTN2, and established a carnal-miRNA-mRNA network. Our study demonstrated the co-regulation of muscle development and signal transduction in AD's progression, and also provided the genetic basis for the following mechanism research with AD.

Abstract
Atherosclerosis (AS) is the most common cardiovascular disease and has limited therapeutic options. IQ motif-containing GTPase-activating protein 1 (IQGAP1) is an important scaffolding protein regulating mitochondrial function influencing endothelial cell activity. Evidence suggests that mitochondrial damage can lead to leakage of mtDNA into the cytoplasm to activate the DNA sensor cGAS-STING to mediate pyroptosis. However, whether IQGAP1 induces NLRP3-mediated endothelial cell pyroptosis by regulating mitochondrial function and activating the DNA sensor cGAS-STING, and its underlying mechanisms remain unclear. In vivo, ApoE-/- C57BL/J and Ldlr-/- C57BL/J mice were pre-injected with adeno-associated virus (AAV) by the tail vein to specifically silence IQGAP1 expression and were fed a high-fat diet (HFD) for 12 weeks. IQGAP1 knockdown reduced mtDNA release and decreased the expression of DNA receptors and pyroptosis-related molecules as determined by immunohistochemistry and immunofluorescence. In vitro, palmitic acid (0.3 mmol/L) was incubated with human umbilical vein endothelial cells (HUVECs) for 24 h. Overexpression of IQGAP1 in HUVECs, flow cytometry, and mitochondrial superoxide staining revealed increased levels of ROS. Moreover, the mitochondrial tracker with dsDNA co-localization showed the release of mtDNA into the cytoplasm increased, which activated the DNA receptor cGAS-STING. Protein blotting and TUNEL staining revealed that IQGAP1 promoted NLRP3-mediated pyroptosis. Furthermore, cGAS or STING small-molecule inhibitors RU.521 or C-176 reverse IQGAP1-promoted HUVECs from undergoing NLRP3-mediated pyroptosis. These results suggest that IQGAP1 promotes oxidative stress and mtDNA release, activates the DNA sensor cGAS-STING, and leads to NLRP3-mediated pyroptosis. The present study provides new insights into the mechanisms underlying AS and identifies new pharmacological targets for treatment.

Abstract
OBJECTIVE To investigate the effect of pachymic acid (PA) against TNBS-induced Crohn's disease (CD)-like colitis in mice and explore the possible mechanism. METHODS Twenty-four C57BL/6J mice were randomized equally into control group, TNBS-induced colitis model group and PA treatment group. PA treatment was administered via intraperitoneal injection at the daily dose of 5 mg/kg for 7 days, and the mice in the control and model groups were treated with saline. After the treatments, the mice were euthanized for examination of the disease activity index (DAI) of colitis, body weight changes, colon length, intestinal inflammation, intestinal barrier function and apoptosis of intestinal epithelial cells, and the expressions of TNF-α, IL-6 and IL-1β in the colonic mucosa were detected using ELISA. The possible treatment targets of PA in CD were predicted by network pharmacology. String platform and Cytoscape 3.7.2 software were used to construct the protein-protein interaction (PPI) network. David database was used to analyze the GO function and KEGG pathway; The phosphorylation of PI3K/AKT in the colonic mucosal was detected with Western blotting. RESULTS PA significantly alleviated colitis in TNBS-treated mice as shown by improvements in the DAI, body weight loss, colon length, and histological inflammation score and lowered levels of TNF-α, IL-6 and IL-1β. PA treatment also significantly improved FITC-dextran permeability, serum I-FABP level and colonic transepithelial electrical resistance, and inhibited apoptosis of the intestinal epithelial cells in TNBS-treated mice. A total of 248 intersection targets were identified between PA and CD, and the core targets included EGFR, HRAS, SRC, MMP9, STAT3, AKT1, CASP3, ALB, HSP90AA1 and HIF1A. GO and KEGG analysis showed that PA negatively regulated apoptosis in close relation with PI3K/AKT signaling. Molecular docking showed that PA had a strong binding ability with AKT1, ALB, EGFR, HSP90AA1, SRC and STAT3. In TNBS-treated mice, PA significantly decreased p-PI3K and p-AKT expressions in the colonic mucosa. CONCLUSION PA ameliorates TNBS-induced intestinal barrier injury in mice by antagonizing apoptosis of intestinal epithelial cells possibly by inhibiting PI3K/AKT signaling.

Abstract
Cardiac ischemia/reperfusion (I/R) injury is a complicated pathological event, which has close association with pyroptosis. This study uncovered the regulatory mechanisms of fat mass and obesity-associated protein (FTO) in NLRP3-mediated pyroptosis during cardiac I/R injury. H9c2 cells were stimulated with oxygen-glucose deprivation/reoxygenation (OGD/R). Cell viability and pyroptosis were detected by CCK-8 and flow cytometry. Western blotting or RT-qPCR was performed to analyze target molecule expression. NLRP3 and Caspase-1 expression was observed by immunofluorescence staining. IL-18 and IL-1β production was detected by ELISA. The total m6A and m6A level of CBL was determined by dot blot assay and methylated RNA immunoprecipitation-qPCR, respectively. The interaction between IGF2BP3 and CBL mRNA was confirmed by RNA pull-down and RIP assays. The protein interaction between CBL and β-catenin and β-catenin ubiquitination were evaluated by Co-IP. Myocardial I/R model was established in rats. We determined infarct size by TTC staining and pathological changes by H&E staining. LDH, CK-MB, LVFS, and LVEF were also assessed. FTO and β-catenin were down-regulated, while CBL was up-regulated by OGD/R stimulation. FTO/β-catenin overexpression or CBL silencing restrained OGD/R-induced NLRP3 inflammasome-mediated pyroptosis. CBL repressed β-catenin expression via ubiquitination and degradation. FTO reduced the mRNA stability of CBL by inhibiting m6A modification. CBL-mediated ubiquitination and degradation of β-catenin were involved in FTO-induced pyroptosis inhibition during myocardial I/R injury. FTO inhibits NLRP3-mediated pyroptosis to attenuate myocardial I/R injury via repressing CBL-induced ubiquitination degradation of β-catenin.

Abstract
Atherosclerosis and its complications constitute some of the major diseases affecting humans worldwide. A core component of atherogenesis is endothelial cell damage and dysfunction, which also includes factors such as adhesion and proliferation of various cells. Multiple studies have shown that atherosclerosis and cancer share a common pathophysiological process and exhibit a degree of similarity. Sparcl-1 is a cysteine-rich secretory stromal cell protein present in the extracellular matrix and belongs to the Sparc family of proteins. Its role in tumor development has been widely investigated; however, its role in cardiovascular diseases has rarely been studied. Sparcl-1 is considered an oncogene correlated with the regulation of cell adhesion, migration, and proliferation and is also related to blood vessel integrity. In this review, the potential link between Sparcl-1 and atherosclerosis development is investigated, and recommendations on future research on the role of Sparcl-1 in atherogenesis are provided.

Abstract
Background We aimed to report the experience of robotic-assisted cardiac surgery (RACS) using the Da Vinci robotic surgical system, meanwhile its efficacy and safety was also evaluated by comparing with traditional open-heart surgery (TOHS), thus to provide evidence for a broader application of RACS in clinical practice. Methods From July 2017 to May 2022, a total of 255 patients who underwent cardiac surgery assisted by Da Vinci robotic surgery system in the First Affiliated Hospital of Anhui Medical University, which included 134 males with an average age of 52.6±6.3 years and 121 females with an average age of 51.8±5.4 years. They were defined as the RACS group. By searching the hospital's electronic medical record information system, 736 patients with the same disease types who underwent median sternotomy and had complete data in the same period were selected as the TOHS group. Intra- and postoperative clinical results of the both groups were compared, and we focused the following indices including surgery time, reoperation rate for postoperative bleeding, length of intensive care unit (ICU) stay, postoperative hospitalization day, the number of died and withdrawing treatments, and the time of patients back to normal daily activities after discharge. Results In RACS group, 2 patients were scheduled to undergo mitral valvuloplasty (MVP), but they had to change to mitral valve replacement (MVR) due to unsatisfactory results; furthermore, 1 patient who received atrial septal defect (ASD) repair experienced abdominal hemorrhage because a rupture of abdominal aorta which were induced by the femoral arterial cannulation, and this patient eventually died of invalid rescue. As for the comparison of clinical results between both groups, there were no significant statistical differences in reoperation rate for postoperative bleeding, and the number of died and withdrawing treatments between both groups. However, length ICU stay, postoperative hospitalization day, and the time of patients back to normal daily activities after discharge was lower in RACS group in addition to the surgery time. Conclusions Compared with TOHS, RACS is safe and effective in clinical and is worthy of promotion in an appropriate place.

Abstract
BACKGROUND A modified aortic arch "island anastomosis" with a stent graft technique was used in 33 patients with acute type A aortic dissection. We retrospectively reviewed our experience of this procedure and the short-term follow-up results. METHODS This retrospective analysis included 33 patients with acute type A aortic dissection undergoing the modified aortic arch island anastomosis with stent graft procedure. Postoperatively, computed tomography angiography images were obtained before discharge and at 12 months. RESULTS All patients underwent successful surgery without intraoperative death. Three patients received dialysis because of postoperative renal insufficiency, 1 patient received tracheotomy because of postoperative respiratory insufficiency, and 5 patients had postoperative delirium. Surgery caused stroke in 1 patient. No paraplegia was found, and no re-exploration for bleeding was performed. One patient died in the hospital due to multiple organ failure, and the other patients were discharged as expected. Only 1 patient had a proximal endoleak, and the patient was stable under close follow-up. The diameter of the descending thoracic aorta was smaller at 12 months postoperatively than preoperatively (34.5±2.5 mm versus 36.7±2.9 mm, P<0.05). The average diameter of the true lumen of the descending thoracic aorta was larger at 12 months postoperatively than preoperatively (24.1±3.1 mm versus 14.9±2.3 mm, P<0.05). CONCLUSIONS The modified aortic arch island anastomosis with stent graft technique is a feasible and safety surgical strategy for acute type A aortic dissection. Short-term outcomes are satisfactory.

Abstract
Background Aortic dissection (AD) is a rare disease with severe morbidity and high mortality. Presently, the pathogenesis of aortic dissection is still not completely clear, and studying its pathogenesis will have important clinical significance. Methods We downloaded 28 samples from the Gene Expression Omnibus (GEO) database (Accession numbers: GSE147026 and GSE190635), including 14 aortic dissection samples and 14 healthy controls (HC) samples. The Limma package was used to screen differentially expressed genes. The StarBasev2.0 tool was used to predict the upstream molecular circRNA of the selected miRNAs, and Cytoscape software was used to process the obtained data. STRING database was used to analyze the interacting protein pairs of differentially expressed genes under medium filtration conditions. The R package "org.hs.eg.db" was used for functional enrichment analysis. Results Two hundred genes associated with aortic dissection were screened. Functional enrichment analysis was performed based on these 200 genes. At the same time, 2720 paired miRNAs were predicted based on these 200 genes, among which hsa-miR-650, hsa-miR-625-5p, hsa-miR-491-5p and hsa-miR-760 paired mRNAs were the most. Based on these four miRNAs, 7106 pairs of circRNAs were predicted to be paired with them. The genes most related to these four miRNAs were screened from 200 differentially expressed genes (CDH2, AKT1, WNT5A, ADRB2, GNAI1, GNAI2, HGF, MCAM, DKK2, ISL1). Conclusions The study demonstrates that miRNA-associated circRNA-mRNA networks are altered in AD, implying that miRNA may play a crucial role in regulating the onset and progression of AD. It may become a potential biomarker for the diagnosis and treatment of AD.

Abstract
OBJECTIVE To investigate the therapeutic mechanism of diosmetin on 2, 4, 6-trinitrobenzene sulfonic acid (TNBS)-induced Crohn's disease (CD)-like colitis in mice. METHODS Wild-type C57BL/6 mice were randomized into control group, TNBS-induced CD-like colitis group (TNBS group) and 50 mg·kg-1·d-1 diosmetin-treated group (n=8). Disease activity (DAI) scores, body weight changes, histological scores, colon lengths and colon mucosal levels of TNF-α, IFN-γ, and IL-17A were measured to evaluate the severity of colitis. The changes of T lymphocyte subsets (Th1/Th2 and Th17/Treg) in the mesenteric lymph nodes were analyzed by flow cytometry. Network pharmacology and molecular docking were used to analyze the effect of diosmetin on PI3K/AKT pathway. RESULTS Compared with TNBS group, diosmetin treatment significantly lowered DAI scores, histological scores, body weight loss and colon mucosal levels of TNF-α, IFN-γ, and IL-17A (P < 0.05) and increased the colon length of the rat models, but these improvements did not reach the control levels (P < 0.05). Diosmetin significantly lowered the percentages of Th1/Th17 cells in the mesenteric lymph nodes in TNBS-treated mice, which remained higher than the control levels (P < 0.05); The percentages of Th2/Treg cells were significantly higher in diosmetin group than in TNBS group (P < 0.05) and the control group (P < 0.05). Network pharmacologic analysis identified 46 intersection targets of diosmetin and CD, and among them AKT1, EGFR, SRC, ESR1, MMP9 and PTGS2 were the top 6 core targets. GO and KEGG analyses showed that the PI3K/AKT signaling pathway was closely related with the therapeutic effect of diosmetin on CD-like colitis. Molecular docking suggested strong binding of diosmetin to the key core targets. Diosmetin significantly reduced the levels of p-PI3K and p-AKT in the colon mucosa in TNBS-treated mice (P < 0.05), but their levels remained higher than those in the control group (P < 0.05). CONCLUSION Diosmetin ameliorates TNBS-induced CDPlike colitis in mice possibly by regulating Th1/Th2 and Th17/Treg balance to improve intestinal immune disorder through inhibition of PI3K/AKT signaling.

Abstract
The bed nuclei of the stria terminalis (BST) is recognised as a pivotal integrative centre for monitoring emotional valence. It is implicated in the regulation of diverse affective states and motivated behaviours, and decades of research have firmly established its critical role in anxiety-related behavioural processes. Researchers have recently intricately dissected the BST's dynamic activities, its connection patterns and its functions with respect to specific cell types using multiple techniques such as optogenetics, in vivo calcium imaging and transgenic tools to unmask the complex circuitry mechanisms that underlie anxiety. In this review, we principally focus on studies of anxiety-involved neuromodulators within the BST and provide a comprehensive architecture of the anxiety network-highlighting the BST as a key hub in orchestrating anxiety-like behaviour. We posit that these promising efforts will contribute to the identification of an accurate roadmap for future treatment of anxiety disorders.

The objective of this study was to examine to what extent the anatomic characteristics of the upper airway can influence the effect of nocturnal wearing of dentures on the sleep of edentulous elders with untreated sleep apnea. This study used the data from a randomized crossover clinical trial and an exploratory approach to address its objectives. Cone beam computed tomography scans of 65 edentulous individuals (female, n = 37; male, n = 28; mean ± SD age, 74.54 ± 6.42 y) with untreated obstructive sleep apnea (OSA) were used to identify anatomic variables. Polysomnography data were collected by means of one portable overnight recording. The respiratory variable values, including apnea-hypopnea index (AHI), with and without denture worn during sleep were used to calculate the change. Statistical analyses included multiple linear regressions, cluster analysis, and binary logistic regressions. A receiver operator characteristic curve was used to illustrate the accuracy of the statistical model. The regression model explained 15.8% (R2) of AHI change. An increase in the lateral dimension of the minimum cross-sectional area was associated with a decrease in AHI, oxygen desaturation index, and respiratory arousal index changes (P ≤ 0.041). Furthermore, an increase in the length of the hypopharynx was associated with an increase in AHI and oxygen desaturation index changes (P ≤ 0.027). An increase in the lateral dimension of the minimum cross-sectional area of the upper airway was associated with a decreased likelihood of being in the group having a worsened AHI (odds ratio = 0.85; 95% CI, 0.76 to 0.95; P = 0.006). An increase in the length of the oropharynx was associated with an increased likelihood of having increased AHI (odds ratio = 1.10; 95% CI, 1.01 to 1.20; P = 0.026). The nocturnal aggravation of respiratory variables in edentulous individuals with OSA who wear dentures at night can be linked to certain anatomic characteristics of the upper airway. Replication of these findings may open novel avenues for personalized advice regarding nocturnal wearing of dentures in edentulous individuals with OSA (ClinicalTrials.gov: NCT01868295).

Abstract
Porphyromonas gingivalis, a major periodontal pathogen, invades autophagosomes of cells, including gingival epithelial cells, endothelial cells, gingival fibroblasts, macrophages, and dendritic cells, to escape antimicrobial autophagy and lysosome fusion. However, it is not known how P. gingivalis resists autophagic immunity, survives within cells, and induces inflammation. Thus, we investigated whether P. gingivalis could escape antimicrobial autophagy by promoting lysosome efflux to block autophagic maturation, leading to intracellular survival, and whether the growth of P. gingivalis within cells results in cellular oxidative stress, causing mitochondrial damage and inflammatory responses. P. gingivalis invaded human immortalized oral epithelial cells in vitro and mouse oral epithelial cells of gingival tissues in vivo. The production of reactive oxygen species (ROS) increased upon bacterial invasion, as well as mitochondrial dysfunction-related parameters with downregulated mitochondrial membrane potential and intracellular adenosine triphosphate (ATP), upregulated mitochondrial membrane permeability, intracellular Ca2+ influx, mitochondrial DNA expression, and extracellular ATP. Lysosome excretion was elevated, the number of intracellular lysosomes was diminished, and lysosomal-associated membrane protein 2 was downregulated. Expression of autophagy-related proteins, microtubule-associated protein light chain 3, sequestosome-1, the NLRP3 inflammasome, and interleukin-1β increased with P. gingivalis infection. P. gingivalis may survive in vivo by promoting lysosome efflux, blocking autophagosome-lysosome fusion, and destroying autophagic flux. As a result, ROS and damaged mitochondria accumulated and activated the NLRP3 inflammasome, which recruited the adaptor protein ASC and caspase 1, leading to the production of proinflammatory factor interleukin-1β and inflammation.

Abstract
Advances in instrumentation and technique have facilitated minimally invasive surgeries for cardiac myxoma treatment. This study aims to compare the clinical outcomes between the thoracoscopic and robotic approaches for myxoma resection. Intraoperative data and postoperative data of 46 patients who underwent either thoracoscopic (n = 15) or robotic (n = 31) cardiac myxoma resection in our center between July 2013 and September 2022 were retrospectively compared. There was no in-hospital death in either group. Meanwhile, the operative time and cardiopulmonary bypass time were significantly shorter in the robotic group than in thoracoscopic group (P = 0.015 and P = 0.035, respectively). Furthermore, shorter ICU stays (P = 0.006), shorter postoperative mechanical ventilation time (P = 0.035) and less thoracic drainage (P = 0.040) were observed in the robotic group. However, the operating room costs and total hospital costs were both significantly lower in thoracoscopic group (P = 0.004 and P = 0.007, respectively). There was no significant difference between two groups regarding the incidence of postoperative complications (P > 0.05). Lastly, a faster return to exercise was noted in robotic group than in thoracoscopic group (Log-Rank χ2 = 4.094, P = 0.043). Both approaches can be safe and feasible for myxoma resection. However, regardless of higher expenses, the robotic myxoma resection approach provides shorter operation time, less postoperative thoracic drainage, and faster recovery than total thoracoscopic technique.

Abstract
OBJECTIVE To analyze the expression of centromere protein U (CENPU) in colorectal cancer and its predictive value for long-term prognosis of the patients. METHODS We retrospectively analyzed the data of 102 patients with colorectal cancer undergoing radical resection in our hospital between January, 2005 and December, 2011. The expression level of CENPU in colorectal cancer tissue was detected immunohistochemically, and its association with clinicopathological characteristics of the patients were analyzed. The patients were divided into low expression group (n=51) and high expression group (n=51) based on the median CENPU expression level for analysis the value of CENPU for predicting long-term prognosis of the patients after radical resection of the tumors. In the in vitro study, we constructed colorectal cancer cell lines with CENPU interference and CENPU overexpression by lentiviral transfection and assessed the changes in the proliferation, migration and invasion of the cells using CCK-8 assay and Transwell assay. RESULTS The protein expression level of CENPU was significantly higher in colorectal cancer tissues than in the adjacent tissues (P < 0.05) and was positively correlated with the expressions levels of Ki67 (r=0.569, P < 0.05) and VEGF-C (r=0.629, P < 0.05). CENPU expression level in colorectal cancer tissue was closely related with tumor progression and clinicopathological stage of the tumor (P < 0.05). Kaplan-Meier survival analysis showed that the patients with high CENPU expression had significantly decreased postoperative overall survival (χ2=11.155, P < 0.05); Cox multivariate regression analysis suggested that CENPU expression level was an independent risk factor affecting the overall survival of the patients after radical resection (HR=1.848, P < 0.05). The results of cell experiments demonstrated that high CENPU expression significantly promoted the proliferation, migration and invasion of the tumor cells. CONCLUSION CENPU is highly expressed in colorectal cancer tissues in closely correlation with tumor progression and may serve as a potential biomarker for evaluating the long-term prognosis of colorectal cancer patients.

Abstract
High temperature requirement A3 (HtrA3) belongs to the HtrA family, and its role in inflammation and myocardial ischemia-reperfusion injury remains unknown. Herein, the study aimed to explore the role of HtrA3 in inflammatory cytokine secretion and the nuclear factor kappa B (NF-κB) signaling pathway in hypoxia-reoxygenation (H/R)-induced H9C2 cardiomyoblasts. H9C2 cells were treated with H/R to mimic myocardial ischemia-reperfusion in vitro. Results showed that HtrA3 expression was significantly downregulated and the expression of inflammatory cytokines was regulated in response to H/R. HtrA3 overexpression decreased the secretion of inflammatory cytokines, whereas HtrA3 knockdown led to increase levels of inflammatory cytokines. And H/R-induced inflammation in H9C2 cells was inhibited by the regulation of the NF-κB signaling pathway. Our findings demonstrate that HtrA3 alleviates H/R-induced inflammatory responses in H9C2 cardiomyoblasts, possibly by suppressing the pro-inflammatory NF-κB signaling pathway.

Abstract
OBJECTIVE To investigate the expression of aldehyde dehydrogenase 3B1 (ALDH3B1) in gastric cancer and explore its correlation with the pathological parameters and long-term prognosis of the patients. METHODS We analyzed the clinical data of 101 patients who underwent radical gastrectomy for gastric cancer in our hospital between January, 2013 and November, 2016, and examined the expression of ALDH3B1 in paraffin-embedded samples of gastric cancer tissues and adjacent tissues from these cases by immunohistochemical staining. We evaluated the correlation between ALDH3B1 expressions and histopathological parameters and assessed the predictive value of ALDH3B1 expression for long-term survival of the patients. We also examined the effect of lentivirus-mediated interference and overexpression of ALDH3B1 on the malignant behaviors of MGC-803 gastric cancer cells. RESULTS The expressions of ALDH3B1 and Ki67 were significantly higher in gastric cancer tissues than in adjacent tissues (P < 0.05). In gastric cancer patients, ALDH3B1 expression was positively correlated with peripheral blood CEA and CA19-9 levels (P < 0.01). The proportion of patients with CEA ≥5 μg/L, CA19-9 ≥37 kU/L, T stage of 3- 4, and N stage of 2-3 was significantly greater in high ALDH3B1 expression group than in low expression group. Kaplan-Meier survival analysis showed that the 5-year survival rate was significantly lower in gastric cancer patients with high ALDH3B1 expressions (P < 0.01). Univariate and Cox multiple regression analyses identified a high expression of ALDH3B1 (P < 0.05, HR= 0.231, 95% CI: 0.064-0.826), CEA≥5 μg/L (P < 0.01, HR=4.478, 95% CI: 1.530-13.110), CA19-9≥37 kU/L (P < 0.01, HR=3.877, 95% CI: 1.625-9.247), T stage of 3-4 (P < 0.01, HR=4.953, 95% CI: 1.768-13.880), and N stage of 2-3 (P < 0.05, HR=2.152, 95% CI: 1.152-4.022) as independent risk factors affecting 5-year survival after radical gastrectomy. The relative ALDH3B1 expression level, at the cut-off point of 4.66, showed a sensitivity of 76.47% and a specificity of 76% for predicting 5-year postoperative death (P < 0.01). In the cell experiment, overexpression of ALDH3B1 obviously promoted the proliferation, migration and invasion of MGC-803 cells. CONCLUSION As an independent risk factor affecting 5-year survival after radical gastrectomy, ALDH3B1 is highly expressed in gastric cancer and correlated with pathological parameters of the tumor, and a high ALDH3B1 expression may promote proliferation, invasion and metastasis of gastric cancer cells.

Abstract
Abstract
Introduction/Objective
Dentate gyrus (DG), a neurogenic niche, is a metabolically dense subregion of the hippocampus. Continuous production and integration of new neurons in the existing circuit and harmonious relationship between excitatory and inhibitory neurons accompanied by neuron-glia coupling is essential to maintain hippocampal homeostasis throughout adulthood. Imbalance in the neuronal activity generates seizures and can result in mesial temporal lobe epilepsy (MTLE). MTLE affects 50 million people across the globe and impairs the overall hippocampal network and its associated functions such as memory and cognition. Although altered lipid metabolism has been associated with status epilepticus, the role of lipid droplets (LDs), the minuscule metabolically active organelle known to provide a substrate for cellular energy, has not been explored in DG during seizure. LDs are composed of neutral lipids and surrounded by phospholipid monolayer, which is studded with a structural Perilipin family of proteins 1-5, reported to be involved in lipid metabolism.
Methods/Case Report
To study LDs in the brain, we used a novel approach by injecting Bodipy, a lipid dye in the tail vein of mice, and successfully labeled LDs in the DG. We used the pilocarpine-induced seizure model. After Bodipy injection followed by seizure induction, mice were sacrificed at four time-points 0.5, 1-, 3- and 18 hours.
Results (if a Case Study enter NA)
We found a significant increase in Bodipy signal and Perilipin 4, LDs specific marker expression at four time-points post-seizure than in the control cohort. To elucidate the role of neuron-glia metabolic coupling in DG, we measured LDs in microglia and astrocytes and found a significant increase in LDs in seizure mice than control groups suggesting the role of glia in lipid regulation in DG.
Conclusion
Overall, this novel study will highlight the undiscovered role of LDs in dentate gyrus during seizure and, in the future, can be used as a therapeutic target to alleviate the MTLE phenotype.

Abstract
Objective: We aimed to: (1) explore the risk factors that affect the prognosis of cardiac surgery-associated acute kidney injury (CS-AKI) in patients undergoing renal replacement therapy (RRT) and (2) investigate the predictive value of the Acute Physiology and Chronic Health Evaluation (APACHE) III score, Sequential Organ Failure Assessment (SOFA) score, and Vasoactive-Inotropic Score (VIS) for mortality risk in patients undergoing RRT. Methods: Data from patients who underwent cardiac surgery from January 2015 through February 2021 were retrospectively reviewed to calculate the APACHE III score, SOFA score, and VIS on the first postoperative day and at the start of RRT. Various risk factors influencing the prognosis of the patients during treatment were evaluated; the area under the receiver operating characteristics curve (AUCROC) was used to measure the predictive ability of the three scores. Independent risk factors influencing mortality were analyzed using multivariable binary logistic regression. Results: A total of 90 patients were included in the study, using 90-day survival as the end point. Of those patients, 36 patients survived, and 54 patients died; the mortality rate reached 60%. At the start of RRT, the AUCROC of the APACHE III score was 0.866 (95% CI: 0.795-0.937), the VIS was 0.796 (95% CI: 0.700-0.892), and the SOFA score was 0.732 (95% CI: 0.623-0.842). The AUCROC-value of the APACHE III score on the first postoperative day was 0.790 (95% CI: 0.694-0.885). After analyzing multiple factors, we obtained the final logistic regression model with five independent risk factors at the start of RRT: a high APACHE III score (OR: 1.228, 95% CI: 1.079-1.397), high VIS (OR: 1.147, 95% CI: 1.021-1.290), low mean arterial pressure (MAP) (OR: 1.170, 95% CI: 1.050-1.303), high lactate value (OR: 1.552, 95% CI: 1.032-2.333), and long time from AKI to initiation of RRT (OR: 1.014, 95% CI: 1.002-1.027). Conclusion: In this study, we showed that at the start of RRT, the APACHE III score and the VIS can accurately predict the risk of death in patients undergoing continuous RRT for CS-AKI. The APACHE III score on the first postoperative day allows early prediction of patient mortality risk. Predictors influencing patient mortality at the initiation of RRT were high APACHE III score, high VIS, low MAP, high lactate value, and long time from AKI to the start of RRT.

Abstract
BACKGROUND Previous studies have shown the association of waiting time in the emergency department with the prognosis of critically ill patients, but these studies linking the waiting time to clinical outcomes have been inconsistent and limited by small sample size. AIM To determine the relationship between the waiting time in the emergency department and the clinical outcomes for critically ill patients in a large sample population. DESIGN A retrospective cohort study of 13 634 patients. METHODS We used the Medical Information Mart for Intensive Care III database. Multivariable logistic regression was used to determine the independent relationships of the in-hospital mortality rate with the delayed time and different groups. Interaction and stratified analysis were conducted to test whether the effect of delayed time differed across various subgroups. RESULTS After adjustments, the in-hospital mortality in the ≥6 h group increased by 38.1% (OR 1.381, 95% CI 1.221-1.562). Moreover, each delayed hour was associated independently with a 1.0% increase in the risk of in-hospital mortality (OR 1.010, 95% CI 1.008-1.010). In the stratified analysis, intensive care unit (ICU) types, length of hospital stay, length of ICU stay, simplified acute physiology score II and diagnostic category were found to have interactions with ≥6 h group in in-hospital mortality. CONCLUSIONS In this large retrospective cohort study, every delayed hour was associated with an increase in mortality. Furthermore, clinicians should be cautious of patients diagnosed with sepsis, liver/renal/metabolic diseases, internal hemorrhage and cardiovascular disease, and if conditions permit, they should give priority to transferring to the corresponding ICUs.

Abstract
BACKGROUND This paper describes a case of a patient with situs inversus totalis (SIT) and dextrocardia in which robotic atrial septal defect (ASD) repair was successfully performed in a beating heart. METHODS AND RESULTS A 45-year-old female patient who had SIT and dextrocardia was diagnosed with secundum ASD 5 years ago. Because of progressive dyspnoea, fatigue, and obvious cough, she came to our hospital for surgical treatment. Transthoracic echocardiography showed the defect located in the middle and lower segments of the atrial septum with a maximum diameter of 27 mm, with a left-to-right shunt. Transcatheter ASD closure could not be performed because there was not enough tissue surrounding the defect. After communicating with the patient, we performed robotic ASD repair in a beating heart using the da Vinci surgical system. The operation was successful, and the patient recovered quickly. CONCLUSION As a minimally invasive approach, robotic cardiac surgery has many advantages and is feasible and safe in suitable patients.

Abstract
The global incidence of myocardial infarction has been consistently high, and it is one of the main causes of poor cardiovascular prognosis. Dexmedetomidine (DEX) is a highly selective α2 receptor agonist. Recent studies have found that DEX has a protective effect on myocardial infarction, but its specific mechanism is still unclear. In this experiment, we permanently ligated the anterior descending branch of mice to explore the protective mechanism of DEX against myocardial infarction. Our study found that intraperitoneal injection of DEX for 7 days after myocardial infarction in mice can increase the reduction of ejection fraction (EF) and fractional shortening (FS) caused by myocardial infarction and significantly reduce the release of serum markers. The results of myocardial HE and Sirius red staining suggest that the changes in the myocardial structure of mice after using DEX are reduced. Immunohistochemistry shows that DEX reduces the expression of ROCK1 protein after myocardial infarction. TUNEL staining and the protein expression levels of cleaved caspase-3 and cleaved caspase-9 were used to detect cell apoptosis and results make clear that DEX can reduce the apoptosis caused by myocardial infarction. Western blot experiments showed that DEX can reduce the expression levels of ROCK1 and ROCK2 (Rho-kinase). At the same time, it was observed that DEX improved the Bcl-2/Bax ratio. The above results indicate that DEX reduces cardiomyocyte apoptosis and improves cardiac function likely through inhibiting the RhoA/ROCK signaling pathway. This study may provide new insights into the protective effect of DEX after myocardial infarction in mice.

Abstract
Increasing evidence has suggested that noncoding RNAs (ncRNAs) have vital roles in cardiovascular tissue homeostasis and diseases. As a main subgroup of ncRNAs, long ncRNAs (lncRNAs) have been reported to play important roles in lipid metabolism, inflammation, vascular injury, and angiogenesis. They have also been implicated in many human diseases including atherosclerosis, arterial remodeling, hypertension, myocardial injury, cardiac remodeling, and heart failure. Importantly, it was reported that lncRNAs were dysregulated in the development and progression of cardiovascular diseases (CVDs). A variety of studies have demonstrated that lncRNAs could influence gene expression at transcription, post-transcription, translation, and post-translation level. Particularly, emerging evidence has confirmed that the crosstalk among lncRNAs, mRNA, and miRNAs is an important underlying regulatory mechanism of lncRNAs. Nevertheless, the biological functions and molecular mechanisms of lncRNAs in CVDs have not been fully explored yet. In this review, we will comprehensively summarize the main findings about lncRNAs and CVDs, highlighting the most recent discoveries in the field of lncRNAs and their pathophysiological functions in CVDs, with the aim of dissecting the intrinsic association between lncRNAs and common risk factors of CVDs including hypertension, high glucose, and high fat. Finally, the potential of lncRNAs functioning as the biomarkers, therapeutic targets, as well as specific diagnostic and prognostic indicators of CVDs will be discussed in this review.

Abstract
Liver fibrosis is a health concern that leads to organ failure mediated via production of inflammatory cytokines and fibrotic biomarkers. To date, there was no direct approved antifibrotic therapy, and current treatment was mainly the removal of the causative factor. Recent studies demonstrated that aberrant expression of miR-124 was involved in the progression of various liver diseases including hepatocellular carcinoma (HCC). However, whether miR-124 could function as a transcriptional regulator in the inflammatory cytokines secretion of liver fibrosis remains unclear. In this study, we demonstrated that the expression of miR-124 was downregulated in liver fibrosis tissues and TNF-α-induced LX-2 cells, concomitant with the upregulated expression of IQGAP1, suggesting that miR-124 and IQGAP1 might be associated with the development of inflammation in liver fibrosis. Therefore, we demonstrated that the overexpression of miR-124 and knockdown of IQGAP1 could lead to the downregulation of TNF-α, IL-1β and IL-6. While knockdown of miR-124 or overexpression of IQGAP1 showed reversed results. Moreover, dual luciferase reporter assays demonstrated that miR-124 specifically targeted the 3'-UTR of IQGAP1, and thus inhibited the expression of IQGAP1. Mechanistically, we found that the expression changes of miR-124 and IQGAP1 could be involved in inhibition or activation of NF-κB signaling pathway in response to TNF-α. In conclusion, these results indicated that miR-124 plays a crucial role in TNF-α-induced LX-2 cells via regulating NF-κB signaling pathway.

Abstract
OBJECTIVE To assess the value of the combination of multiple proteins in predicting the prognosis of colorectal cancer (CRC) through bioinformatics analysis. OBJECTIVE The protein expression and clinical data were downloaded from TCPA database. Perl and R were used to screen the prognostic-related proteins, and through Cox analysis, the proteins that served as independent prognostic factors of CRC were identified to build the prediction model. Survival analyses were conducted for each of the proteins included in the prediction model and the risk score of the model, and risk curves was drawn for the risk score and the patients' survival status to verify the performance of the model. Independent prognosis analysis and ROC analysis were used to assess the value and advantages of the model in prognosis prediction. The interactions between the proteins included in the model and the differential expressions of the key genes related with the proteins were analyzed. OBJECTIVE Six proteins were screened for model construction. Compared with a single gene, the model showed much greater prognostic value for CRC. Independent prognostic analysis showed that the risk score of the prediction model was significantly related with the prognosis (P < 0.001), and the model could be used as an independent risk factor for prognostic assessment of the patients. ROC analysis showed that the model had good specificity and sensitivity for prognostic prediction (AUC=0.734). Protein interactions showed that BID, SLC1A5 and SRC_pY527 were significantly correlated with other proteins (P < 0.001), and SLC1A5 and SRC_pY527 had the most significant interactions with other proteins (P < 0.001). Except for those of INPP4B, the key genes related with the proteins in the prediction model had significant differential expressions at the mRNA level in CRC (P < 0.05). OBJECTIVE The prediction model constructed based on 6 proteins has good prognostic value for CRC. The proteins SLC1A5 and SRC_pY527 play key roles in the prognosis of CRC, and SRC_pY527 may regulate the occurrence and progression of CRC through the SRC/AKT/MAPK signal axis and thus may serve as a new therapeutic target of CRC.

Abstract
Lung cancer is the leading cause of cancer-related death globally. Ubiquitin modification plays a crucial role in the regulation of gene expression, and is closely associated with cancer pathogenesis. The aim of our study was to clarify the role and mechanisms of action for HECT, C2 and WW domain containing E3 ubiquitin protein ligase 1 (HECW1) in non-small cell lung cancer (NSCLC). Herein, we demonstrate that the expression of HECW1 was significantly increased in NSCLC cell lines and tissues. Upregulation of HECW1 markedly enhanced the proliferation of NSCLC cells, whereas downregulation of HECW1 significantly inhibited proliferation. Moreover, the expression levels of HECW1 positively correlated with the migration and invasiveness of NSCLC cells. Upregulation or downregulation of HECW1 only affected the protein expression levels of SMAD family member 4 (Smad4), but had no effect on the mRNA expression levels. Furthermore, after treatment with MG-132, the relative protein level of Smad4 significantly increased in NSCLC cells. HECW1 promoted the proliferation, migration, and invasiveness of NSCLC cells by inducing the ubiquitination and degradation of Smad4, thus our data provide a novel target for NSCLC treatment.

Abstract
Background For patients who undergo mechanical valve replacement, the greatest disadvantage is that they require long-term or permanent use of anticoagulant therapy to prevent thromboembolism. To date, mechanical valve replacement without anticoagulation has been published in the literature. Case summary We present the case of a 75-year-old female who underwent mechanical mitral valve replacement (MVR) on mid-June, 2007. However, this patient had not been taking anticoagulant medication since she experienced warfarin overdose in the first month after the operation. She had been well without using any anticoagulation, and there were no complications of the mechanical valve. Discussion There was no thrombosis for such a long period of time because she suffered from FX deficiency. To the best of our knowledge, she may be the only patient who has been well without any anticoagulation since not taking warfarin 12 years ago.

Abstract
Smoking is an important factor in the pathogenesis of chronic obstructive pulmonary disease (COPD), which is commonly characterised by cellular senescence and inflammation. Recently, miR-200b has emerged as an important target to cure lung disease; however, the function of miR-200b in reducing cellular senescence and inflammatory responses has not been reported. In this study, we found that miR-200b was downregulated in the lungs of COPD model mice, and its expression is correlated with cellular senescence and inflammatory responses. We hypothesised that miR-200b may be a potential novel therapy for treating COPD. We performed senescence-Associated-β-galactosidase (SA-β-GAL) staining, western blot, qRT-PCR and ELISA; our data suggested that miR-200b is an anti-aging factor in the lungs that is involved in inflammatory responses. We also confirmed that ZEB2 (Zinc finger E-box binding homeobox 2) is a target gene of miR-200b using luciferase reporter assay. In addition, we verified the function of ZEB2 in cellular senescence and inflammatory responses through transfection experiments. Moreover, we found that the protective effects of miR-200b are inhibited when cells overexpress the ZEB2 protein. In conclusion, our results suggest that miR-200b may attenuate cellular senescence and inflammatory responses by targeting ZEB2 in pulmonary emphysema.

Abstract
Obesity drives the development of nonalcoholic fatty liver disease (NAFLD) characterized by hepatic steatosis. Several bone morphogenetic proteins (BMPs) except BMP9 were reported related to metabolic syndrome. This study demonstrates that liver cytokine BMP9 is decreased in the liver and serum of NAFLD model mice and patients. BMP9 knockdown induces lipid accumulation in Hepa 1-6 cells. BMP9-knockout mice exhibit hepatosteatosis due to down-regulated peroxisome proliferator-activated receptor α (PPARα) expression and reduced fatty acid oxidation. In vitro, recombinant BMP9 treatment attenuates triglyceride accumulation by enhancing PPARα promoter activity via the activation of p-smad. PPARα-specific antagonist GW6471 abolishes the effect of BMP9 knockdown. Furthermore, adeno-associated virus-mediated BMP9 overexpression in mouse liver markedly relieves liver steatosis and obesity-related metabolic syndrome. These findings indicate that BMP9 plays a critical role in regulating hepatic lipid metabolism in a PPARα-dependent manner and may provide a previously unknown insight into NAFLD therapeutic approaches.

Abstract
E3 ubiquitin ligase gene, WWP2, is associated with acute kidney injury (AKI). This research was conducted to explore the role of WWP2 in AKI. AKI cell model was produced in human renal proximal tubular epithelial cell line (HK-2) by ischemia-reperfusion (IR) injury. CCK8 and flow cytometry assay were performed to explore the influence of WWP2 overexpression on cell proliferation and apoptosis of IR-induced HK-2 cells. Quantitative real-time PCR and immunoblotting (IB) were performed to assess the gene and protein expression. Then, the influence of WWP2 on p53 ubiquitylation and degradation was estimated by immunoprecipitation assay. Our data indicated that WWP2 was down-regulated and p53 was up-regulated in IR-induced HK-2 cells. WWP2 overexpression promoted proliferation and inhibited apoptosis of IR-induced HK-2 cells. And WWP2 interacted with p53 and regulated p53 ubiquitylation and degradation. Furthermore, the influence of WWP2 on cell proliferation and apoptosis was rescued by MG132 (proteasome inhibitor) treatment. In conclusion, our work described for the first time the role of WWP2 in AKI, showing that WWP2 ameliorated AKI by mediating p53 ubiquitylation and degradation. Moreover, the study offers some important insights into the occurrence of AKI and WWP2 may be a novel target of AKI treatment. SIGNIFICANCE OF THE STUDY: Our data elaborates that WWP2 has protective effect against AKI by mediating p53 ubiquitylation and degradation. Thus, WWP2 might be a therapeutic target for AKI.

Abstract
Background To explore the effects of the respiratory rate (RR) on the venous-to-arterial CO2 tension difference (gapCO2) in septic shock patients undergoing volume mechanical ventilation. Methods Adult patients with septic shock underwent volume mechanical ventilation between October 2015 and October 2016. RR was started at 10 breaths/min, and 2 breaths/min were added every 60 min until 16 breaths/min was reached. At every point, central venous and arterial blood gas measurements were obtained simultaneously. Results In this study, gapCO2 induced by hyperventilation significantly increased, while the central venous carbon dioxide pressure (PvCO2) and the partial pressure of CO2 (PaCO2) in arteries decreased. The decreasing trend of the PaCO2 was more obvious than that of the PvCO2. HCO3− and ctCO2 were markedly decreased, when the RR was increased (P < 0.05). Central venous oxygen saturation (ScvO2) had a decreasing trend between 14 (77.1 ± 8.3%) and 16 (75.2 ± 8.7%) breaths/min; however, the difference was not significant. Conclusions In septic patients undergoing ventilation, respiratory alkalosis induced by hyperventilation caused an increase in the gapCO2. Clinicians should cautiously interpret the gapCO2 in hemodynamically stable ventilated septic shock patients and its relationship with low cardiac output and inadequate perfusion.

Abstract
Objective: Safety and immunogenicity regarding simultaneous vaccination on both hepatitis E and hepatitis B vaccines were studied. Methods: A total of 600 healthy subjects aged 18-60 were recruited in Chaoyang district of Beijing city, from September 2015 to December 2016. Subjects meeting the inclusion and exclusion criteria were randomly divided into 3 groups: the simultaneous vaccination group of hepatitis E and hepatitis B, the hepatitis B vaccination group and the hepatitis E vaccination group. Members of the 3 groups were all inoculated according to the procedure of '0, 1 and 6 months'. Safety and immunogenicity of the simultaneous vaccination group was compared with the individual vaccination groups. Results: Vaccination groups had 601 subjects, involved with having 150 subjects of hepatitis E vaccination group, 159 subjects of hepatitis B vaccination group, and 292 subjects of simultaneous vaccination of hepatitis E and hepatitis B. Local adverse reactions that mostly common seen, would include pain (25.0%, 73/292), redness (12.7%, 37/292), pruritus (9.2%, 27/292), callus (8.9%, 26/292), swelling (8.2%, 24/292) at the inoculation sites. Systemic adverse reactions would include fever (7.2%, 21/292), headache (5.8%, 17/292), muscle pain (5.5%, 16/292) and fatigue (3.4%, 10/292). No serious adverse reactions associated with vaccination were seen. In addition to the higher incidence of pain at the inoculation sites, rest of the adverse reactions was similar to the simultaneous vaccination group or the individual vaccination groups. One month after the completed immunization process, positive rate and geometric mean concentration(GMC) of the HBsAb were not inferior to that of the hepatitis B vaccine group (94.2% vs. 93.8%, 611.6 WU/ml vs. 745.1 WU/ml). Positive rate and GMC of the HEV IgG were not inferior to that of the hepatitis E vaccinated group (98.8% vs. 100.0%, 11.0 WU/ml vs. 18.0 WU/ml). Conclusions: Simultaneous vaccination strategy on hepatitis E and hepatitis B vaccines showed good safety and immunogenicity. It is recommended that hepatitis E and hepatitis B vaccines should be administered to the susceptible population at the same time, in order to protect the liver functions.

Abstract
The objective of this study is to explore changes in main immune cells during acute coronary syndrome (ACS), including changes in subsets of monocytes, T cells, and inhibitory myeloid-derived suppressor cells (MDSCs), and to evaluate possible mechanisms. A total of 50 patients suffering from ACS were divided into two subgroups based on attacks of acute infarction, acute myocardial infarction (AMI) with infarction including ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI), and unstable angina (UA). Third, the subgroup of 19 healthy subjects was labeled the normal group (NG). CD14, CD16, and CD45 were used as markers of the subset of monocytes. CD4, CD8, and CD3 were used as markers of the subset of T cells and CD14, human leukocyte antigen—DR isotype (HLA-DR), and CD45 were used as markers of inhibitory MDSCs. Both CD11b+ CD206+ and CD11b+ CD68+ cells were also assayed. Our data indicated that lymphocytes/karyocytes and monocytes/karyocytes as well as those of CD3+ CD4+ T cells, CD14+ CD16– monocytes, CD14+ CD16+ monocytes, and CD11b+ CD68+ monocytes were significant in all three groups ( P < 0.05). The ratio of T-cell subtypes to total lymphocytes among the three subgroups can be represented as AMI > UA > NG ( P < 0.05). The ratios of CD14+ monocytes to total karyocytes among the three subgroups can be represented as NG > UA > AMI ( P < 0.05). The ratios of CD14+ CD16– monocytes to total karyocytes among the three subgroups can be represented as NG > UA > AMI ( P < 0.05). The ratios of CD14+ CD16+ monocytes to total karyocytes among the three subgroups can be represented as AMI > UA > NG ( P < 0.05). There were no significant differences in the proportion of MDSCs ( P > 0.05). Certain subsets of monocytes are closely associated with ACS, of which CD14+ CD16– monocytes present a negative association, while CD14+ CD16+ monocytes show a positive association. In addition, adaptive immunity is associated with unstable plaques of ACS, and CD3+ CD4+ T cells may play a role in early stages of ACS.
