Abstract
Although there have been advancements in electrochemical catalysts for luteolin detection, their practical use is constrained by low sensitivity, inadequate selectivity, and unsatisfactory limit of detection. MXene, a class of 2D materials, possesses exceptional physical-chemical properties that make it highly suitable for electrochemical detection. Nevertheless, the self-stacking and limited interlayer spacing of MXene impede its extensive application in electrochemical detection. Herein, a SnO2 QDs-MXene composite is synthesized for selective electrochemical detection of luteolin. Inserting SnO2 QDs between tightly stacked MXene layers expands the d-spacing of MXene, enhancing the specific surface area and enabling abundant active sites for redox reactions. The inclusion of MXene in the modified SnO2 QDs-MXene/GCE electrode significantly enhances electron transfer. As a result, the electrode demonstrates exceptional luteolin detection capabilities, including a wide linear range (0.1-1200 nM), high sensitivity (12.4 μA μM-1), and an ultra-low limit of detection (0.14 nM). Additionally, the SnO2 QDs-MXene/GCE electrode exhibits good repeatability, excellent reproducibility, remarkable stability, and high selectivity, making it suitable for practical sample analysis. This research contributes to advancing ultra-low limit of detection sensors for accurate luteolin detection.

Abstract
OBJECTIVES Previous studies have reported satisfactory long-term results of mitral valve (MV) repair for rheumatic mitral disease. However, the effects of this procedure in isolated rheumatic mitral stenosis remain unclear. In addition, protective effects of MV repair on cardiac function have not been verified in rheumatic MV disease. This study retrospectively evaluated early mortality and mid-term results of MV repair for isolated rheumatic mitral stenosis in a mid-volume cardiac centre, and explored the effects of this procedure on cardiac function. METHODS Between January 2015 and May 2021, 360 patients with isolated rheumatic mitral stenosis and combined (concomitant) atrial fibrillation (AF) underwent MV repair (100 patients) or MV replacement (260 patients). Perioperative characteristics were compared between the two groups and a regression analysis for early mortality and mid-term left ventricular ejection fraction was conducted. In addition, mid-term survival was compared between the two groups. RESULTS Baseline characteristics of the two groups were balanced after matching. Compared with patients in the replacement group, patients with MV repair had a lower occurrence of postoperative hypotension and AF. There was no difference in early mortality or mid-term survival between the two groups. However, MV repair was associated with a higher mid-term left ventricular ejection fraction. During follow-up, four thromboembolic events and four haemorrhagic events occurred in the replacement group. No blood coagulation-related complications occurred in the repair group. CONCLUSION Mitral valve repair for isolated rheumatic mitral stenosis and concomitant AF was feasible in a mid-volume cardiac centre, with satisfactory perioperative results and mid-term outcomes. Furthermore, this procedure preserved mid-term left ventricular systolic function.

Abstract
BACKGROUND Myocardial ischemia reperfusion injury (MIRI), the tissue damage which is caused by the returning of blood supply to tissue after a period of ischemia, greatly reduces the therapeutic effect of treatment of myocardial infarction. But the underlying functional mechanisms of MIRI are still unclear. METHODS We constructed mouse models of MIRI, extracted injured and healthy myocardial tissues, and performed transcriptome sequencing experiments (RNA-seq) to systematically investigate the dysregulated transcriptome of MIRI, especially the alternative splicing (AS) regulation and RNA binding proteins (RBPs). Selected RBPs and MIRI-associated AS events were then validated by RT-qPCR experiments. RESULTS The differentially expressed gene (DEG) analyses indicated that transcriptome profiles were changed by MIRI and that DEGs' enriched functions were consistent with MIRI's dysregulated pathways. Furthermore, the AS profile was synergistically regulated and showed clear differences between the mouse model and the healthy samples. The exon skipping events significantly increased in MIRI model samples, while the opposite cassette exon events significantly decreased. According to the functional analysis, regulated alternative splicing genes (RASGs) were enriched in protein transport, cell division /cell cycle, RNA splicing, and endocytosis pathways, which were associated with the development of MIRI. Meanwhile, 493 differentially expressed RBPs (DE RBPs) were detected, most of which were correlated with the changed ratios of AS events. In addition, nine DE RBP genes were validated, including Eif5, Pdia6, Tagln2, Vasp, Zfp36l2, Grsf1, Idh2, Ndrg2, and Uqcrc1. These nine DE RBPs were correlated with RASGs enriched in translation process, cell growth and division, and endocytosis pathways, highly consistent with the functions of all RASGs. Finally, we validated the AS ratio changes of five regulated alternative splicing events (RASEs) derived from important regulatory genes, including Mtmr3, Cdc42, Cd47, Fbln2, Vegfa, and Fhl2. CONCLUSION Our study emphasized the critical roles of the dysregulated AS profiles in MIRI development, investigated the potential functions of MIRI-associated RASGs, and identified regulatory RBPs involved in AS regulation. We propose that the identified RASEs and RBPs could serve as important regulators and potential therapeutic targets in MIRI treatment in the future.

Abstract
Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

Abstract
BACKGROUND Moderate/severe aortic regurgitation (AR) with concomitant mitral regurgitation (MR) is a common multiple valve disease for which treatment strategies are controversial. The current study explored long-term outcomes of concomitant MR after AR surgery and the effect of combined mitral valvuloplasty. METHODS A total of 506 patients with moderate/severe AR and concomitant MR undergoing aortic valve surgery between January 2013 and December 2021 in our cardiac center were enrolled. Risk factors for early mortality, late mortality and persistent MR were identified by logistic regression and generalized linear mixed model. RESULTS At least one follow-up record was available for 96.3% patients up to May 2022 and 264 (66.8%) patients had no or trivial MR, 112 (28.4%) had mild MR, 16 (4.1%) had moderate MR and 3 (0.8%) patients had severe MR. Persistent MR was recorded for 92 (23.3%) patients during follow-up. Combined mitral valvuloplasty (odds ratio: 0.23; 95% confidential interval: 0.08-0.64; p = 0.005) and better left ventricular reverse remodeling (odds ratio: 0.99; 95% confidential interval: 0.986-0.996); p < 0.001) were found likely to reduce the possibility of persistent MR during follow-up. CONCLUSIONS Most patients with moderate/severe AR and concomitant MR had a good long-term post-surgical outcome for MR. However, a few had persistent MR during follow-up. Combined mitral valvuloplasty and better left ventricular reverse remodeling reduced the possibility of long-term persistent MR.

Abstract
Objectives Mitral regurgitation (MR) is commonly experienced by patients with aortic insufficiency (AI), and in its mild form, it is considered benign. However, the progression of concomitant mild regurgitation after the aortic valve surgery (AVS) for AI is poorly characterized. The current study aimed to define the long-term outcomes of MR after surgery and identify the risk factors involved in deterioration. Methods Patients presenting with moderate/severe AI and concomitant mild MR (n = 347) between January 2013 and December 2021 were enrolled. MR grade was assessed by transthoracic echocardiography during the follow-up, and deterioration is defined as an increase in grade to moderate or severe MR from the previous follow-up echocardiography. Analysis of risk factors for early mortality, MR deterioration, and long-term mortality was performed. Results A total of 278 patients (84.8%) among 328 survivors had at least one follow-up echocardiography, and complete follow-up occurred for 316 patients (96.3%). Mild MR improved to trivial or none in 194 patients (69.8%), progressed to persistent mild MR for 74 patients (26.6%), and deteriorated for 10 patients (3.6%). Preoperative atrial fibrillation [odds ratio (OR), 23.09; 95% confidence interval (CI), 4.35-122.54] and rheumatic AI (OR, 11.61; 95% CI, 1.26-106.85) were shown to be independent risk factors for MR deterioration by generalized linear mixed analysis. Conclusion Progression of concomitant mild MR is rare in patients with AI after AVS. However, rheumatic AI and preoperative atrial fibrillation increase the probability of MR deterioration. Careful follow-up for this cohort of patients is recommended.

Abstract
Background Many countries and regions have established multicenter registration studies to improve the outcomes of acute type A aortic dissection (ATAAD). Objectives The aims of this study were to report actual preoperative management, surgery type, and early outcomes of surgical treatment for ATAAD in China. Methods This cohort study uses data from the China Registry of Type A Aortic Dissection, a national clinical registry to investigate management of patients with Stanford type A aortic dissection. The data, including surgical management and outcomes of patients with ATAAD, were analyzed from January 2018 to December 2021. Results A total of 1,058 patients with ATAAD were enrolled in this study between January 2018 and December 2021. The mean age of all patients was 51.6 ±11.7 years. The median interval from onset to hospital was 10.65 hours (IQR: 6-24 hours), and the median interval from entering the emergency room to starting operation was 13 hours (IQR: 4.08-28.7 hours). Total arch repair was performed in 938 patients (88.7%), and frozen elephant trunk repair was performed in 800 patients (75.6%). The incidence of early mortality was 7.6%. Conclusions The population of patients with ATAAD in China experienced a longer interval from onset to arrival at the hospital, received more extensive aortic arch repair, and showed a relatively lower early mortality. These findings suggest that there may be a huge survivor bias in patients with ATAAD in China, more efforts should be made to promote prehospital emergency care and preoperative management of Chinese ATAAD patients.

Abstract
OBJECTIVE To explore the role of P2X7 receptor (P2X7R) in migration and invasion of mouse Lewis lung cancer (LLC) cells and examine the tumorigenic ability of LLC cells in P2X7R-knockout mice. METHODS RT-PCR was used to examine P2X7R mRNA expression in LLC cells. LLC cells were treated with ATP (as a P2X7R agonist) or 2'- 3'- O- (4-benzoyl- benzoyl)-ATP (BzATP) (a P2X7R agonist) with or without pretreatment with P2X7R antagonist oxATP or A438079. The changes in migration and invasive abilities of the cells were evaluated using wound healing assay and Transwell assay; Western blotting was performed to determine the activation level of the key proteins in the AKT signaling pathway. The effects of BzATP, A438079, and LY294002 (a inhibitor of the PI3K/AKT pathway) on migration and invasion of LLC cells were also examined. In wild-type (WT) and P2X7R knockout (P2X7-/-) C57BL/6 mice, the growth of subcutaneous LLC cell xenografts were observed by measuring tumor volume and weight. RESULTS P2X7R expression was detected in LLC cells. Treatment with P2X7R agonist significantly enhanced migration and invasion abilities of LLC cells, and this effect was inhibited by application of P2X7R antagonists (P < 0.001). Western blotting showed that BzATP treatment of LLC cells significantly increased the expression level of p-AKT protein, which was obviously lowered by treatment with P2X7R antagonist (P < 0.01). P2X7R antagonist strongly inhibited BzATP-induced enhancement of LLC cell migration and invasion (P < 0.001). In the tumor- bearing mice, the tumor volume and weight were significantly lower in P2X7-/- mice than in WT mice (P < 0.05). CONCLUSION P2X7R promotes migration and invasion of LLC cells by activating the AKT signaling pathway, and LLC cells show lowered tumorigenic capacity in P2X7-/- mice.

Abstract
Objective: To investigate the clinical, genetic, and clonality related aspects of individuals with Richter transformation (RT) . Methods: From January 2019 to December 2021, 18 RT patients with diagnoses at the First Affiliated Hospital of Nanjing Medical University (Pukou CLL center) were retrospectively examined. The immunoglobin heavy variable (IGHV) gene usage and IGHV-D-J rearrangement pattern of diagnosed CLL/SLL and transformed diffuse large B-cell lymphoma (DLBCL) were compared to determine the clonality relatedness. To investigate the risk factors of RT, Clinical and laboratory data from patients with newly diagnosed CLL/SLL and transformed DLBCL were gathered. Results: The median age of RT was 56.5 (41-75) years old. 17 patients transformed to DLBCL and 1 transformed to Hodgkin lymphoma (HL) . Of 17 individuals who had DLBCL transformation, 15 had CLL/SLL-related clonality and 2 had unrelated clonality. Next-generation sequencing (NGS) analysis of 11 paired initially diagnosed treatment-naive CLL/SLL and RT DLBCL found that EGR2、TP53 and NOTCH1 were among the most frequently mutated genes both in treatment-naive CLL/SLL and in RT DLBCL. In several cases, specific mutations were gained or lost throughout RT, indicating clonal evolution. Among 10 patients before exposure to BTK inhibitors before RT, four patients acquired BTK mutation. The aforementioned mutations should be considered high-risk variables for transformation; in addition, TP53 and EGR2 mutations could be linked to a poor prognosis following RT in patients receiving a cocktail of new medicines. Conclusion: Most RT DLBCL patients in our center are clonality related (15/17, 88.2% ) and we recommend all qualified centers to evaluate clonality relatedness of RT DLBCL patients. There was some variability in the mutational landscape between DLBCL that had undergone a transformation and initially diagnosed, treatment-naive CLL/SLL. The underlying molecular mechanism of RT needs more research.

Abstract
Objective: To analyze the differences in immunophenotype, cytogenetics, and molecular biology between typical and atypical immunophenotype chronic lymphocytic leukemia (CLL) , and explore the correlation of cytogenetic anomalies with gene mutations. Methods: This study included 488 patients diagnosed in the First Affiliated Hospital of Nanjing Medical University between November 2014 and May 2021. Of these, 382 patients scored 4-5 points, which was typical CLL (tCLL) , and 106 scored 3 points, which was atypical CLL (aCLL) as per the Royal Marsden Hospital Immunomarker Integral System. Peripheral blood cells were collected for immunophenotype by multiparameter flow cytometry in 488 patients, fluorescence in situ hybridization (FISH) was employed to detect cytogenetic anomalies in 359 patients, and gene mutations were detected by next-generation sequencing (NGS) in 330 patients. Results: The positive rates of CD10, CD22, CD49d, CD81, and FMC7 were significantly higher in the aCLL compared with the tCLL group (P=0.020, P<0.001, P<0.001, P=0.027, and P<0.001, respectively) , while the positive rates of CD5, CD23, CD148, and CD200 were lower in the former compared to the latter (P<0.001, P=0.017, P=0.041, and P<0.001, respectively) . aCLL exhibited a higher frequency of trisomy 12 and lower frequency of del (13q14) compared to the tCLL group (P<0.001 and P<0.001, respectively) . Moreover, aCLL patients also showed a higher incidence of NOTCH1 mutations than the tCLL patients (P=0.038) , while no statistically significant differences in other gene mutations occurred between the two groups. No significant differences in overall survival (OS) and treatment-free survival (TFS) occurred between aCLL and tCLL using Kaplan-Meier analysis (P>0.05) . Conclusion: aCLL has characteristic immunophenotype, cytogenetic, and somatic mutation that differ from tCLL, and this can provide reliable information for the diagnosis and differential diagnosis between the two groups.

Abstract
The main purpose of our study was to evaluate the efficacy and safety of eltrombopag plus cyclosporine A (CsA) in transfusion-dependent non-severe aplastic anemia(TD-NSAA). The clinical characteristics of 13 TD-NSAA patients who received initial treatment of eltrombopag plus CsA from 2019 to 2021 were retrospectively analyzed. The 3-month overall hematological response (OR) rate was 12/13. Until the end of follow-up, 12 patients responded, among whom 2 patients reached complete response (CR) and 9 patients reached partial response (PR) and 1 with HR. Paroxysmal nocturnal hemoglobinuria (PNH) developed in one patient at 6 months after treatment. Five of thirteen patients reported mild adverse reactions, which were all manageable. Compared with historical data, the combination of eltrombopag with CsA is an effective regimen in patients with TD-NSAA.

Abstract
Background Acute renal failure (ARF) is the most common major complication following cardiac surgery for acute aortic syndrome (AAS) and worsens the postoperative prognosis. Our aim was to establish a machine learning prediction model for ARF occurrence in AAS patients. Methods We included AAS patient data from nine medical centers (n = 1,637) and analyzed the incidence of ARF and the risk factors for postoperative ARF. We used data from six medical centers to compare the performance of four machine learning models and performed internal validation to identify AAS patients who developed postoperative ARF. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was used to compare the performance of the predictive models. We compared the performance of the optimal machine learning prediction model with that of traditional prediction models. Data from three medical centers were used for external validation. Results The eXtreme Gradient Boosting (XGBoost) algorithm performed best in the internal validation process (AUC = 0.82), which was better than both the logistic regression (LR) prediction model (AUC = 0.77, p < 0.001) and the traditional scoring systems. Upon external validation, the XGBoost prediction model (AUC =0.81) also performed better than both the LR prediction model (AUC = 0.75, p = 0.03) and the traditional scoring systems. We created an online application based on the XGBoost prediction model. Conclusions We have developed a machine learning model that has better predictive performance than traditional LR prediction models as well as other existing risk scoring systems for postoperative ARF. This model can be utilized to provide early warnings when high-risk patients are found, enabling clinicians to take prompt measures.

Abstract
Objective: To explore the difference of high-risk factors between early-onset and late-onset pre-eclampsia, and to further understand high-risk factors of pre-eclampsia. Methods: Clinical data of pre-eclampsia pregnant women in 160 medical institutions in China in 2018 were retrospectively analyzed, including 8 031 cases of early-onset pre-eclampsia and 12 969 cases of late-onset pre-eclampsia. The proportion of high-risk factors, different body mass index (BMI) and age stratification between early-onset group and late-onset group were compared. Results: (1) Univariate analysis of high-risk factors: the proportions of high-risk factors in early-onset group and late-onset group were compared, and the differences were statistically significant (all P<0.05). Among them, the proportions of primipara and multiple pregnancy in early-onset group were lower than those in late-onset group, while the proportions of pregnant women with advanced age, irregular antenatal examination, obesity, family history of hypertension, pre-eclampsia, diabetes, kidney diseases, immune system diseases and assisted reproductive technology were higher than those in late-onset group. (2) Hierarchical analysis of BMI: the proportion of pregnant women with BMI≥24 kg/m2 in early-onset group [48.2% (2 828/5 872) vs 45.5% (4 177/9 181), respectively; P=0.001] and the proportion of pregnant women with BMI ≥28 kg/m2 in early-onset group [19.5% (1 143/5 872) vs 18.0% (1 656/9 181), respectively; P=0.028] were significantly higher than those in late-onset group. (3) Age stratification analysis: the proportion of pregnant women aged 35-39 years in the early-onset group [21.8% (1 748/8 023) vs 17.5% (2 110/12 068), respectively; P<0.01], the proportion of pregnant women 40-44 years old [6.8% (544/8 023) vs 5.4% (648/12 068), respectively; P<0.01], and the proportion of pregnant women ≥45 years old [0.7% (58/8 023) vs 0.5% (57/12 068), respectively; P=0.021] were significantly higher than those in the late-onset group. (4) Multivariate analysis: advanced age (≥35 years old), multiple pregnancy, irregular antenatal examination or transfer from other hospitals, family history of hypertension (including paternal, maternal and parental lines), previous history of pre-eclampsia, kidney diseases, immune system diseases (systemic lupus erythematosus, antiphospholipid antibody syndrome) and assisted reproductive technology pregnancy were the risk factors affecting the severity of pre-eclampsia (all P<0.05). Conclusion: Pregnant women with high risk factors such as age ≥35 years old, BMI ≥24 kg/m2 before pregnancy, family history of hypertension, history of pre-eclampsia, chronic kidney diseases, immune diseases (mainly including systemic lupus erythematosus and antiphospholipid syndrome) and assisted reproductive technology are more likely to have early-onset pre-eclampsia.

Abstract
BACKGROUND Intrinsic cardiac impairment in Marfan syndrome (MFS) has been explored in many clinical studies; however, their results have been inconsistent. This meta-analysis aimed to assess the difference in cardiac structure and function between Marfan patients and healthy individuals, and to verify the hypothesis of intrinsic cardiac impairment in MFS. METHODS Electronic searches for studies were performed in the PubMed, Embase, and Cochrane Library databases. Nine studies with 490 patients with MFS and 478 controls were included in the analysis. Age and sex were strictly matched between Marfan patients and healthy controls in every study. RESULTS There was no difference in the left ventricular end systolic diameter index (mean difference [MD]: 0.33; 95% confidence interval [CI]: (-0.24, 0.89); p = 0.26) and left ventricular end diastolic diameter index (MD: 0.18; 95% CI: [-0.47, 0.83]; p = 0.58) between Marfan patients and controls. Marfan patients showed larger left ventricular end systolic volume index (MD: 2.62; 95% CI: [0.27, 4.97]; p = 0.03) and left ventricular end diastolic volume index (MD: 4.16; 95% CI: [2.70, 5.63]; p < 0.01) than the control group. Furthermore, Marfan patients showed a lower left ventricular ejection fraction than healthy people (MD: -2.59%; 95% CI: [-4.64%, -0.54%]; p = 0.01). CONCLUSIONS Intrinsic cardiac impairment was observed in MFS. MFS patients showed the larger left ventricular volume and poorer left ventricular function than matched controls. Considering the potentially adverse impact on cardiac function, intrinsic cardiac impairment in MFS should be considered during the cardiac surgery.

Abstract
Prevention and management of myocardial ischemia/reperfusion (I/R) injury is a key step in coronary heart disease surgery. Luteolin is a falconoid compound that has an antioxidant effect, but its mechanism in I/R injury in vivo and in vitro is still under explored. This study attempted to reveal the role of luteolin (Lut) in I/R through mediation of the Src homology 2 domain-containing protein tyrosine phosphatase 1 (SHP-1)/Signal transducer and activator of transcription 3 (STAT3) pathway. To establish I/R rat models, the left anterior descending artery (LAD) was ligated for 30 min and re-perfused for 1 h in Lut-pretreated or nude rats. Comparisons between infarct area, cardiac dysfunction, and myocardial cell death and inflammatory reaction were performed in I/R-induced rats. Hypoxia/reoxygenation (H/R) cell models were established by stimulating H9c2 cells with 95% nitrogen and 5% carbon dioxide. Simultaneously, H/R-related cell death and inflammatory reactions were investigated following Lut treatment. The target protein of Lut was identified using western blotting. Pro-inflammatory cytokines were also measured in serum or Lut-pretreated cell culture medium. The results revealed that compared with the I/R group, Lut treatment could significantly decrease myocardial infarction (MI) area, increase left ventricular ejection fraction (LVEF), and decrease cell death and pro-inflammatory cytokines in the serum. Decreased apoptosis and inflammatory cytokines were also observed in H/R cells after Lut treatment. Lut treatment downregulated SHP-1 expression and subsequently upregulated STAT3 phosphorylation in both I/R rat heart tissue and H9c2 cells. The findings of the current study suggest that Lut can protect the heart and reduce MI area, cell apoptosis rate, and inflammatory level in I/R models.

Abstract
Background To evaluate the early prognosis and management of acute coronary involvement (ACI) in type A aortic dissection (ATAAD) patients without myocardial ischemia (MI). Methods We conducted a retrospective cohort study on a multicenter database. A total of 931 ATAAD patients without MI underwent thoracic aortic surgery between 2018 and 2019 in the Acute Aortic Syndrome Cooperation Network (AASCN) and were enrolled in our study. Patients were divided into two groups: ACI group and non-ACI group. Results There were 139 ACI patients (14.9%) and 792 non-ACI patients (85.1%) in our cohort. ACI group had higher 30-day mortality after surgery than non-ACI group (log-rank test: P = 0.028,Cox regression: hazard ratio [HR], 2.3; 95% confidence interval [95% CI], 1.1–5.39; P = 0.047), especially in sub-group of advanced age (53–80 years; HR, 4.0; 95% CI, 1.3–12.8; P = 0.017), low diastolic blood pressure (29-69 mmHg, HR, 3.8; 95% CI, 1.3–11.2; P = 0.018), low systolic blood pressure (51–119 mmHg, HR, 3.6; 95% CI, 1.1–12.4; P = 0.040), high body mass index (BMI;27.25–47.52 kg/m2; HR, 3.7; 95% CI, 1.3–10.7; P = 0.015) and high hemoglobin (>145 g/L; HR, 4.3; 95% CI, 1.2–16.0; P = 0.030). Acute renal failure was significant more in ACI group than non-ACI group (24.5% vs. 15.9%; P = 0.014). Conclusions ACI increases the short-term postoperative mortality and acute renal failure in ATAAD patients without MI. ATAAD patients with ACI may need a narrower control range of blood pressure even if without myocardial ischemia. Trial registration ChiCTR1900022637. Retrospectively registered 19 April 2019.

Abstract
AIMS This study aimed to elucidate the role of microRNAs (miRNAs) during myocardial infarction (MI) development in vivo and in vitro. MAIN METHODS Differentially expressed miRNAs between heart tissue from the MI mouse model and the control mouse were identified via microarray. Quantitative PCR (qPCR) and western blotting (WB) were performed to examine the expression levels of miRNAs and proteins, respectively. EdU-staining and colony formation assay were performed to assess cell viability and growth. Annexin V- and PI-staining-based flow cytometry was used to assess cell apoptosis. An MI mouse model was also established to study the function of miR-1278 in vivo. KEY FINDINGS The levels of miR-1278 were reduced in the infarct regions of heart tissues of the MI mouse model and in H2O2-treated newborn murine ventricular cardiomyocytes (NMVCs) compared to those in the heart tissues of healthy mice and non-treated NMVCs. H2O2 treatment suppressed the proliferation of NMVCs, while miR-1278 upregulation improved it. Moreover, we found that miR-1278 inhibited the upregulation of IL-22 and CXCL14 expression in H2O2-treated NMVCs by directly binding with the 3'-UTRs of both IL-22 and CXCL14. Furthermore, restoration of IL-22 and CXCL14 in H2O2-treated NMVCs promoted miR-1278-induced inflammation and apoptosis. Administration of agomiR-1278 to the MI mouse model significantly improved cardiac activity. SIGNIFICANCE Collectively, our findings illustrate that the expression of miR-1278 is low in H2O2-treated NMVCs and post-MI cardiac tissues, and the overexpression of miR-1278 in these protects against cell death by modulating IL-22 and CXCL14 expression.

Abstract
Pulmonary artery aneurysm (PAA) is a relatively rare disease. The symptoms are usually nonspecific and often identified due to coughing or dyspnea. Pericardial tamponade caused by the PAA dissection or rupture is the most common cause of death, so active surgical treatment is recommended. The surgical reports in the literature are handful. Here we report three cases, all of whom were admitted due to exertional dyspnea. PAAs were observed from the main to the left and/or the right pulmonary artery. All three cases received PAA resection and artificial graft replacement with good outcomes.

Abstract
Malignant transformation of basal cell adenoma is extremely rare. We report the case of a 63-year-old Chinese woman, who had noticed a slowing growing mass in her right parotid gland with slight pain for 1 month. Based on physical and ultrasound examinations, a diagnosis of benign salivary gland tumour was made before the surgery. A frozen biopsy was performed, and the diagnosis was basal cell adenoma, with the tumour cells infiltrating the capsule. Routine histopathological examination was performed after the surgery, and a final diagnosis of intracapsular basal cell adenocarcinoma ex basal cell adenoma was made. The patient received a further total parotidectomy and recovered well without any evidence of facial nerve palsy. This case suggests that during frozen biopsy, adequate sectioning including the capsule should be made. With regard to the treatment, we suggest a complete excision of the tumour with tumour-free margins, without any additional auxiliary therapy.

Abstract
Objective: To explore the interaction of smoking and diabetes on stroke. Methods: In this case-control study, a face to face questionnaire survey was conducted. Logistic regression models were used to analyze the relationship between smoking or diabetes and stroke. The indicators of interaction were calculated according to the Bootstrap method in this study. Results: A total of 918 cases and 918 healthy controls, who participated in the chronic disease risk factor survey in Xuzhou in 2013, were included in this study. Logistic regression analysis found that cigarette smoking was associated with stroke (OR=1.63, 95%CI: 1.33-2.00), and diabetes was also associated with stroke (OR=2.75, 95%CI: 2.03-3.73) after adjusting confounders. Compared with those without diabetes and smoking habit, the odds ratio of stroke in those with diabetes and smoking habits was 8.94 (95%CI:3.77-21.19). Diabetes and smoking combined interaction index was 3.65 (95%CI: 1.68-7.94), the relative excess risk was 5.77 (95%CI: 0.49-11.04), the attributable proportion was 0.65 (95%CI: 0.42-0.87). Conclusion: The results suggest that there are additive interactions between smoking and diabetes on stroke.

Abstract
Glutathione S-transferases are one of the most important antioxidant enzymes to protect against oxidative damage induced by reactive oxygen species. In this study, a novel gst gene, designated as hsgst, was derived from Antarctic sea ice bacterium Halomonas sp. ANT108 and expressed in Escherichia coli (E. coli) BL21. The hsgst gene was 603 bp in length and encoded a protein of 200 amino acids. Compared with the mesophilic EcGST, homology modeling indicated HsGST had some structural characteristics of cold-adapted enzymes, such as higher frequency of glycine residues, lower frequency of proline and arginine residues, and reduced electrostatic interactions, which might be in relation to the high catalytic efficiency at low temperature. The recombinant HsGST (rHsGST) was purified to apparent homogeneity with Ni-affinity chromatography and its biochemical properties were investigated. The specific activity of the purified rHsGST was 254.20 nmol/min/mg. The optimum temperature and pH of enzyme were 25 °C and 7.5, respectively. Most importantly, rHsGST retained 41.67% of its maximal activity at 0 °C. 2.0 M NaCl and 0.2% H₂O₂ had no effect on the enzyme activity. Moreover, rHsGST exhibited its protective effects against oxidative stresses in E. coli cells. Due to its high catalytic efficiency and oxidative resistance at low temperature, rHsGST may be a potential candidate as antioxidant in low temperature health foods.

Abstract
Phase-change memory is one of the most promising candidates for future memory technologies. However, most of the phase-change memories are based on chalcogenides, while other families of materials for this purpose remain insufficiently studied. In this work, we investigate the optical properties and microstructure of Ga16Sb84 by an in-situ ellipsometer and X-ray diffraction. Our experimental results reveal that the Ga16Sb84 films exhibit a relatively high crystallization temperature of ~250 °C, excelling in long data retention. In addition, a large optical contrast exists between the amorphous and crystalline states, which may make it suitable for use in optical discs. Molecular dynamics simulations indicate that a unique local structure order in the amorphous and crystalline phases is responsible for the optical properties observed in the experiment. The similarity found in the short-range orders of the amorphous and crystalline phases is beneficial to better understanding the fast phase transition of phase-change memory.

Abstract
This paper aims to provide a fast, sensitive, and accurate characterization of a Mass Flow Controller (MFC) based gas mixer. The gas mixer was evaluated by using a hollow waveguide based laser spectral sensor with high efficiency. Benefiting from the sensor's fast response, high sensitivity and continuous operation, multiple key parameters of the mixer, including mixing uncertainty, linearity, and response time, were acquired by a one-round test. The test results show that the mixer can blend multi-compound gases quite efficiently with an uncertainty of 1.44% occurring at a flow rate of 500 ml/min, with the linearity of 0.998 43 and the response time of 92.6 s. The results' reliability was confirmed by the relative measurement of gas concentration, in which the isolation of the sensor's uncertainty was conducted. The measured uncertainty has shown well coincidence with the theoretical uncertainties of the mixer, which proves the method to be a reliable characterization. Consequently, this sort of laser based characterization's wide appliance on gas analyzer's evaluations is demonstrated.

Abstract
Inhibition of myostatin, a negative growth modulator for muscle, can functionally enhance muscle mass and improve glucose and fat metabolism in myostatin propeptide (MPRO) transgenic mice. This study was to investigate whether myostatin inhibition by adeno-associated virus (AAV)-mediated gene delivery of MPRO could improve muscle mass and achieve therapeutic effects on glucose regulation and lipid metabolism in the db/db mice and the mechanisms involved in that process. Eight-week-old male db/db mice were administered saline, AAV-GFP and AAV-MPRO/Fc vectors and monitored random blood glucose levels and body weight for 36 weeks. Body weight gain was not different during follow-up among the groups, but AAV-MPRO/Fc vectors resulted high level of MPRO in the blood companied by an increase in skeletal muscle mass and muscle hypertrophy. In addition, AAV-MPRO/Fc-treated db/db mice showed significantly lower blood glucose and insulin levels and significantly increased glucose tolerance and insulin sensitivity compared with the control groups (P<0.05). Moreover, these mice exhibited lower triglyceride (TG) and free fatty acid (FFA) content in the skeletal muscle, although no difference was observed in fat pad weights and serum TG and FFA levels. Finally, AAV-MPRO/Fc-treated mice had enhanced insulin signaling in the skeletal muscle. These data suggest that AAV-mediated MPRO therapy may provide an important clue for potential clinical applications to prevent type II diabetes, and these studies confirm that MPRO is a therapeutic target for type II diabetes.

Abstract
Trimetazidine is a piperazine-derived metabolic agent, which exerts cell protective effects and has been reported to be efficient in the treatment of chronic stable angina pectoris. In addition, it has been shown to exert protection against acute myocardial infarction. The present study aimed to investigate whether trimetazidine protects against cardiac ischemia/reperfusion (I/R) injury, and to determine whether its curative effects are associated with microRNA (miRNA)-21 expression, Akt, and the B-cell lymphoma 2 (Bcl-2)/Bcl-2-associated X protein (Bax) pathway. Cardiac I/R injury was induced by ligating the left anterior descending coronary artery in adult rats. Subsequently, cardiac function was evaluated, and the expression levels of miRNA-21, Bcl-2, Bax and phosphorylated-Akt were detected using quantitative polymerase chain reaction and western blotting. The results indicated that trimetazidine was able to significantly protect cardiac function and reduce infarct size in rats following cardiac I/R injury. Furthermore, trimetazidine significantly promoted miRNA-21 expression and phosphorylated-Akt protein expression, and reduced the Bcl-2/Bax ratio in rats following cardiac I/R injury. Knockdown of miRNA-21 using anti-miR-21 plasmids was able to reverse the protective effects of trimetazidine against cardiac I/R injury. These results indicated that miRNA-21 serves a protective role in cardiac I/R injury via Akt and the Bcl-2/Bax pathway. In addition, trimetazidine exerts protective effects against cardiac I/R injury through cardiac miRNA-21 expression, Akt, and the Bcl-2/Bax pathway. Therefore, the present study provided evidence regarding the protective effects of miRNA-21 on cardiac I/R injury following treatment with trimetazidine in vivo.

Abstract
Adipose-derived stem cells demonstrate promising effects in promoting cutaneous wound healing, but the mechanisms are still not well defined and contradictory views are still debatable. In the present research, we established a mouse cutaneous wound model and investigated the effects of adipose-derived stem cells in wound healing. Adipocyte, adipose-derived stem cells, and epidermal keratinocyte stem cells were isolated from younger and aged donors according to the standard protocol. The conditioned medium either from adipose-derived stem cells or from adipocytes was used to treat epidermal keratinocyte cells. The results showed that adipocytes or adipose-derived stem cells isolated from younger donors demonstrated mild advantage over those cells isolated from aging donors. Adipose-derived stem cells showed stronger stimuli than adipocytes, and the adipose-derived stem cells or adipocytes from younger donors enabled to support higher growth rate of keratinocyte stem cells. The invasion of vasculature was observed at day 10 after posttransplantation in the mice bearing the keratinocyte stem cells or combination of keratinocyte stem cells with adipose-derived stem cells; however, simply inoculating keratinocyte stem cells from aging donors did not result in vasculature formation. Adipose-derived stem cells isolated from younger donors were able to inspire the host's self-healing capabilities, and age-associated factors should be taken into consideration when designing a feasible therapeutic treatment for skin regeneration.

Abstract
BACKGROUND/AIMS Deregulation of microRNAs (miRNAs) expression is a frequent event in cancer development and progression. Recent studies have implied that abnormal expression of miRNAs is frequently observed in non-small cell lung cancer (NSCLC). Here, we examined the levels and biological functions of miR-509-5p in NSCLC. METHODS The levels of miR-509-5p were measured by real-time quantitative PCR (RT-PCR) in NSCLC cell lines and NSCLC tissues along with adjacent normal tissues. Cell viability was analyzed by MTT and colony formation assay. Cell migration and invasion were evaluated by transwell and wound healing assay. In addition, we predicted the putative targets of miR-509-5p by bioinformatics analyses. Moreover, by luciferase-reporter assay, we analyzed the relationship between miR-509-5p and the target in NSCLC cells. RESULTS miR-509-5p expression was significantly reduced in NSCLC tissues compared with adjacent normal tissues. In addition, miR-509-5p decreased cell proliferation, migration and invasive capability of NSCLC cells. Moreover, we found that FOXM1 was a putative target of miR-509-5p. Enforced miR-509-5p expression in NSCLC cells reduced both mRNA and protein levels of FOXM1. Furthermore, dual-luciferase reporter assay showed miR-509-5p could bind to the 3' untranslational regions of FOXM1 mRNA. Furthermore, overexpression of FOXM1 reversed cell viability, migration, invasion and vimentin levels suppressed by miR-509-5p mimics in H1299 cells. CONCLUSIONS miR-509-5p exerts tumor-suppressive effects by attenuating FOXM1 in NSCLC. Collectively, these findings provide further evidence that miR-509-5p may be considered as a novel and potential target for the diagnosis, prognosis and treatment of NSCLC.

Abstract
OBJECTIVE To summarize the outcome of tricuspid valve replacement.
METHODS A total of 28 patients (15 males and 13 females) underwent tricuspid valve replacement from March 2000 to February 2015 in the First Affiliated Hospital of Zhengzhou University were recruited. Among them, 16 patients were Ebstein's anomaly, 7 had rheumatic valve heart disease, 3 and 2 suffered from infective endocarditis and degenerative tricuspid lesions, respectively.
RESULTS One patient died of multiple organ failure. Four patients were implanted permanent cardiac pacemaker because of third degree atrioventricular block occurring in the 5th day (2 patients) and in the 9th day (2 patients) after the operation, respectively. Twenty-seven patients were followed up from 1 month to 15 years. The prosthetic valves and permanent pacemakers worked well.
CONCLUSION Third degree of atrioventricular block, mostly appearing in early postoperative period, is the most common and severe complication of tricuspid valve replacement. The key point for prevention of damage is to accurately identify the anatomical relationship among the tricuspid valve, atrioventricular node, and conduction bundle.

Abstract
Atherosclerosis is a leading cause of death worldwide and is characterized by lipid-laden foam cell formation. Recently, pycnogenol (PYC) has drawn much attention because of its prominent effect on cardiovascular disease (CVD). However, its protective effect against atherosclerosis and the underlying mechanism remains undefined. Here PYC treatment reduced areas of plaque and lipid deposition in atherosclerotic mice, concomitant with decreases in total cholesterol and triglyceride levels and increases in HDL cholesterol levels, indicating a potential antiatherosclerotic effect of PYC through the regulation of lipid levels. Additionally, PYC preconditioning markedly decreased foam cell formation and lipid accumulation in lipopolysaccharide (LPS)-stimulated human THP-1 monocytes. A mechanistic analysis indicated that PYC decreased the lipid-related protein expression of adipose differentiation-related protein (ADRP) and adipocyte lipid-binding protein (ALBP/aP2) in a dose-dependent manner. Further analysis confirmed that PYC attenuated LPS-induced lipid droplet formation via ADRP and ALBP expression through the Toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB) pathway, because pretreatment with anti-TLR4 antibody or a specific inhibitor of NF-κB (PDTC) strikingly mitigated the LPS-induced increase in ADRP and ALBP. Together, our results provide insight into the ability of PYC to attenuate bacterial infection-triggered pathological processes associated with atherosclerosis. Thus PYC may be a potential lead compound for the future development of antiatherosclerotic CVD therapy.

Abstract
AIM Efficiently inhibiting the formation of macrophage foam cells is indispensable for mitigating and treating atherosclerosis. Tenascin-C (TN-C) plays an important role in promoting atherosclerosis; therefore, it is essential to inhibit foam cell formation associated with TN-C for controlling atherosclerosis. Activating transcription factor 3 (ATF3) is one of the factors involved in regulating the complex process of foam cell formation. This study aimed to explore the role of TN-C and ATF3 in LPS-stimulated THP-1-derived macrophages. METHODS RT-PCR was used for evaluating the expression of TN-C in LPS-stimulated THP-1 macrophages. Further, exogenous TN-C was introduced and incubated with cultured THP-1 macrophages to confirm the effect of TN-C on LPS-stimulated THP-1 macrophages. ATF3-modified THP-1 macrophages were constructed and verified by western blot. High performance liquid chromatography (HPLC) assay and Oil red O staining were applied for detecting cholesteryl ester/total cholesterol (CE/TC) and lipid formation in THP-1 macrophages. RESULTS The expression of TN-C was determined to be upregulated in LPS-stimulated THP-1 macrophages in a dose- and time-dependent manner. HPLC assay and Oil red O staining confirmed that TN-C can enhance LPS-induced THP-1 macrophage foam cell formation. Moreover, ATF3 can act as a negative regulatory factor for inhibiting TN-C-induced foam cell formation by suppressing TLR-4 in LPS-stimulated THP-1 macrophages. CONCLUSION ATF3 can inhibit TN-C-induced foam cell formation in LPS-stimulated THP-1 macrophages by suppressing TLR-4. It may be a useful molecular target to control TN-C-induced foam cell formation in atherosclerosis.

Abstract
BACKGROUND Large animal cardiopulmonary bypass (CPB) models are expensive, and prevent assessment of neurocognitive function, and difficulties with long-term recovery. The purpose of this study was to establish a novel rat model of cardiopulmonary bypass for deep hypothermic circulatory arrest without blood priming. METHODS Twenty adult male Sprague-Dawley rats weighing 450-560 g were randomized to CPB with deep hypothermic circulatory arrest (DHCA) and control groups, with 10 rats each. The experimental protocols, including blood and crystalloid fluid administration, anesthesia, orotracheal intubation, ventilation, cannulation, and heparinization were identical in both groups. After inducing cardiac arrest, the circuit was turned off and rats were left in a DHCA state for 15 minutes. Rats were rewarmed to 34°C to 35°C over a period of 36 to 42 minutes using CPB-assisted rewarming, a heating blanket, and a heating lamp along with administration of 0.1 mEq of sodium bicarbonate and 0.14 mEq of calcium chloride. The remaining priming volume was reinfused and animals were weaned from CPB. RESULTS All CPB with DHCA processes were successfully achieved. Blood gas analysis and hemodynamic parameters were in the normal range. The vital signs of all rats were stable. CONCLUSIONS Our CPB circuit has several novel features, including a small priming volume, active cooling/rewarming processes, vacuum-assisted venous drainage, peripheral cannulation without thoracotomy or sternotomy, and an accurate means of monitoring peripheral tissue oxygenation.

Abstract
BACKGROUND Cardiopulmonary bypass (CPB) has been shown to be associated with systemic inflammatory response leading to postoperative organ dysfunction. Elucidating the underlying mechanisms and developing protective strategies for the pathophysiological consequences of CPB have been hampered due to the absence of a satisfactory recovery animal model. The purpose of this study was to establish a novel, minimally invasive rat model of normothermic CPB model without blood priming. METHODS Twenty adult male Sprague-Dawley rats weighing 450-560 g were randomly divided into CPB group (n = 10) and control group (n = 10). All rats were anaesthetized and mechanically ventilated. The carotid artery and jugular vein were cannulated. The blood was drained from the right atrium via the right jugular and further transferred by a miniaturized roller pump to a hollow fiber oxygenator and back to the rat via the left carotid artery. The volume of the priming solution, composed of 6% HES 130/0.4 and 125 IU heparin, was less than 12 ml. The surface of the hollow fiber oxygenator was 0.075 m(2). CPB was conducted for 60 minutes at a flow rat of 100-120 ml × kg (-1)× min(-1) in CPB group. Oxygen flow/perfusion flow was 0.8 to 1.0, and the mean arterial pressure remained 60-80 mmHg. RESULTS All CPB processes were successfully achieved. Blood gas analysis and hemodynamic parameters of each time point were in accordance with normal ranges. The vital signs of all rats were stable. CONCLUSIONS The establishment of CPB without blood priming in rats can be achieved successfully. The nontransthoracic model should facilitate the investigation of pathophysiological processes concerning CPB-related multiple organ dysfunction and possible protective interventions. This novel, recovery, and reproducible minimally invasive CPB model may open the field for various studies on the pathophysiological process of CPB and systemic ischemia-reperfusion injury in vivo.

Abstract
Hepatocellular carcinoma (HCC) is one of the most deadly cancers worldwide. It is well known that the activation of PI3K/AKT/mTOR and the Ras/MAPK signaling pathway plays a critical role in cellular metabolism, growth and proliferation, and its inhibitors have been used as therapeutic drugs for hepatocellular carcinoma. Cetuximab, a chimerical monoclonal EGFR IgG1 antibody, can block the binding of EGF or other ligands to EGFR and thus inhibit ligands-induced receptor phosphorylation. In the present study, we found that rapamycin could enhance the antiproliferation effect of cetuximab in both HepG2 cells and Huh-7 cells and arrest the cell cycle. Cetuximab in combination with rapamycin had synergistic effects on inhibiting the phosphrylation of proteins in PI3K/AKT/mTOR and Ras/MAPK signaling pathway. Combination of cetuximab with rapamycin treatment significantly suppressed the HCC development in HepG2 cells-xenografted mice and improved the survival. Cetuximab and rapamycin inhibited the growth of HCC both in vitro and in vivo. These results suggest that the combination therapy using the inhibitors for both EGFR and PI3K/AKT/mTOR signaling pathways may be a novel therapeutic approach for HCC.

Abstract
OBJECTIVE Minimally invasive cardiac surgery is becoming a safe and cosmetic alternative to standard median sternotomy (SMS). In the present retrospective study, we reviewed our results and experience with the totally thoracoscopic (TTS) and right vertical infra-axillary thoracotomy (RVIAT) techniques for atrial septal defect closure compared with SMS. METHODS From December 2010 to February 2012, 198 patients underwent repair of atrial septal defect using the TTS technique (n = 66), RVIAT (n = 59), or SMS (n = 73). Cardiopulmonary bypass was achieved peripherally in the TTS group and directly in the RVIAT and SMS groups. RESULTS The procedures were performed successfully in all 3 groups, and no in-hospital mortality occurred. No patient required conversion to SMS in the TTS group, although 2 patients did so in the RVIAT group. The cardiopulmonary bypass time was 87.26 ± 21 minutes in the TTS group, 41.81 ± 13.97 minutes in the RVIAT group, and 36.99 ± 10.84 minutes in the SMS group (P < .01). The crossclamp time was 32.86 ± 13.36, 22.54 ± 9.08, and 19.23 ± 6.92 minutes in the TTS, RVIAT, and SMS groups, respectively (P < .01). The total incision length in the SMS group (7.45 ± 1.54 cm) was longer than that in the other groups (TTS group, 5.21 ± 0.63 cm; RVIAT group, 6.48 ± 1.37 cm); the difference was statistically significant (P < .01). CONCLUSIONS The TTS technique and RVIAT can both be performed with favorable cosmetic and acceptable clinical results for closing atrial septal defects. They are promising alternatives to SMS and merit additional study.

Abstract
Oroxylin A is a major active component of the Chinese traditional medicinal plant Scutellaria baicalensis Georgi, which has been reported as a potential anticancer drug. We demonstrated that, Oroxylin A inhibited the glycolysis and the binding of hexokinase II (HK II) with mitochondria in human breast carcinoma cell lines, which was dependent on sirtuin-3 (SIRT3). The level of SIRT3 in mitochondria was increased by Oroxylin A. Then SIRT3 deacetylated cyclophilin D, diminished its peptidyl-prolyl cis-trans isomerase activity and induced its dissociation from the adenine nucleotide translocator. Finally, SIRT3-induced inactivation of cyclophilin D resulted in the detachment of mitochondrial HK II and the inhibition of glycolysis. These results have important implications for the metabolism reprogramming effect and the susceptibility to Oroxylin A-induced mitochondrial cytotoxicity through the regulation of SIRT3 in breast carcinoma.

Abstract
OBJECTIVE To determine the use of septal plication with Dor or Cooley procedure for post infarction anterior and anterior-septal aneurysm of the left ventricle. METHODS A total of 23 patients with post infarction anterior and anterior-septal aneurysm of the left ventricle underwent septal plication and Dor or Cooley procedure along with coronary artery bypass grafting concomitantly. Data of NYHA grading, left ventricular end diastolic volume index (LVEDVI), left ventricular end systolic volume index (LVESVI) and left ventricular ejection fraction (LVEF) were recorded before the surgery, before discharge and 3 months after the surgery. RESULTS Compared with the preoperative data, the NYHA grading before the discharge and 3 months after the surgery improved from 3.21 ± 0.62 to 1.72 ± 0.31 and 1.57 ± 0.23(P<0.05); LVEDVI decreased from (102.31 ± 18.71) mL/m² to (62.11 ± 6.21) mL/m² and (54.63 ± 4.54) mL/m² (P<0.05); LVESVI decreased from (69.32 ± 17.48) mL/m² to (30.23 ± 3.25)mL/m² and (28.34 ± 3.12) mL/m²; while LVEF increased from (32.92 ± 8.12)% to (48.78 ± 4.51)% and (50.52 ± 4.68)% (P<0.05), respectively. CONCLUSION Ventricular septal plication combined with Dor or Cooley procedure can remarkably improve the left heart function in patients with post infarction ventricular aneurysm.

Abstract
Adeno-associated virus (AAV) has become a leading gene transfer vector for striated muscles. However, the AAV vectors also exhibit broad tropisms after systemic delivery. In an attempt to improve muscle tropism, we inserted a 7-amino-acid (ASSLNIA) muscle-targeting peptide (MTP) in the capsids of AAV2 at residue 587 or 588, generating AAV587MTP and AAV588MTP. In vitro studies showed that both viruses diminished their infectivity on non-muscle cell lines as well as on un-differentiated myoblasts, however, preserved or enhanced their infectivity on differentiated myotubes. AAV587MTP, but not AAV588MTP, also abolished its heparin-binding capacity and infected myotubes in a heparin-independent manner. Furthermore, in vivo studies by intravenous vector administration in mice showed that AAV587MTP enhanced its tropism to various muscles and particularly to the heart (24.3 fold of unmodified AAV2), whereas reduced its tropism to the non-muscle tissues such as the liver, lungs and spleen, etc. This alteration of tissue tropism is not simply due to the loss of heparin-binding, since a mutant AAV2 (AAVHBSMut) containing heparin-binding site mutations lost infectivity on both non-muscle and muscle cells. Furthermore, free MTP peptide, but not the scrambled control peptide, competitively inhibited AAV587MTP infection on myotubes. These results suggest that AAV2 could be re-targeted to the striated muscles by a muscle-targeting peptide inserted after residue 587 of the capsids. This proof of principle study showed first evidence of peptide-directed muscle targeting upon systemic administration of AAV vectors.
