Abstract
Low-tannin sorghum is an excellent energy source in pig diets. However, sorghum contains several anti-nutritional factors that may have negative effects on nutrient digestibility. The impacts of proteases on growth performance, nutrient digestibility, blood parameters, and gut microbiota of growing pigs fed sorghum-based diets were studied in this study. Ninety-six pigs (20.66 ± 0.65 kg BW) were allocated into three groups (eight pens/group, four pigs/pen): (1) CON (control diet, sorghum-based diet included 66.98% sorghum), (2) PRO1 (CON + 200 mg/kg proteases), (3) PRO2 (CON + 400 mg/kg proteases) for 28 d. No differences were observed in growth performance and apparent total tract digestibility (ATTD) of nutrients between CON and PRO1 groups. Pigs fed PRO2 diet had increased (P < 0.05) BW on d 21 and 28, and increased (P < 0.05) average daily gain during d 14-21 and the overall period compared with pigs fed CON diet. In addition, pigs fed PRO2 diet had improved (P < 0.05) ATTD of gross energy, CP, and DM compared with pigs fed CON and PRO1 diets. Pigs fed PRO2 diet had lower (P < 0.05) plasma globulin (GLB) level and higher (P < 0.05) plasma glucose, albumin (ALB) and immunoglobulin G levels, and ALB/GLB ratio than pigs fed CON and PRO1 diets. Furthermore, pigs fed PRO2 diet had decreased (P < 0.05) the relative abundance of Acidobacteriota at the phylum level and increased (P < 0.05) the relative abundance of Prevotella_9 at the genus level. The linear discriminant analysis effect size analysis also showed that pigs fed PRO2 diet had significantly enriched short-chain fatty acid-producing bacteria, such as Subdoligranulum and Parabacteroides. In conclusion, protease supplementation at 400 mg/kg improved the growth performance of growing pigs fed sorghum-based diets, which may be attributed to the improvement of nutrient digestibility, host metabolism, immune status and associated with the altered gut microbiota profiles.

Abstract
Methionine is indispensable for growth and meat formation in pigs. However, it is still unclear that increasing dietary sulphur-containing amino acid (SAA) levels using different methionine sources affects the growth performance and meat quality of barrows and gilts. To investigate this, 144 pigs (half barrows and half gilts) were fed the control (100% SAA, CON), DL-Methionine (125% SAA, DL-Met)-supplemented, or OH-Methionine (125% SAA, OH-Met)-supplemented diets during the 11-110 kg period. The results showed that plasma methionine levels varied among treatments during the experimental phase, with increased plasma methionine levels observed following increased SAA consumption during the 25-45 kg period. In contrast, pigs fed the DL-Met diet had lower plasma methionine levels than those fed the CON diet (95-110 kg). Additionally, gilts fed the DL-Met or OH-Met diets showed decreased drip loss in longissimus lumborum muscle (LM) compared to CON-fed gilts. OH-Met-fed gilts had higher pH45min values than those fed the CON or DL-Met diets, whereas OH-Met-fed barrows had higher L45min values than those fed the CON or DL-Met diets. Moreover, increased consumption of SAA, regardless of the methionine source, tended to decrease the shear force of the LM in pigs. In conclusion, this study indicates that increasing dietary levels of SAA (+25%) appeared to improve the meat quality of gilts by decreasing drip loss and increasing meat tenderness.

Abstract
BACKGROUND Patients with chronic kidney disease (CKD) undergoing coronary angiography (CAG) are at high risk of contrast-associated acute kidney injury (CA-AKI) and mortality. Therefore, there is a clinical need to explore safe, convenient, and effective strategies for preventing CA-AKI. OBJECTIVES This study sought to assess whether simplified rapid hydration is noninferior to standard hydration for CA-AKI prevention in patients with CKD. METHODS This multicenter, open-label, randomized controlled study was conducted across 21 teaching hospitals and included 1,002 patients with CKD. Patients were randomized to either simplified hydration (SH) (SH group, with normal saline from 1 hour before to 4 hours after CAG at a rate of 3 mL/kg/h) or standard hydration (control group, with normal saline 12 hours before and 12 hours after CAG at a rate of 1 mL/kg/h). The primary endpoint of CA-AKI was a ≥25% or 0.5-mg/dL rise in serum creatinine from baseline within 48 to 72 hours. RESULTS CA-AKI occurred in 29 of 466 (6.2%) patients in the SH group and in 38 of 455 (8.4%) patients in the control group (relative risk: 0.8; 95% CI: 0.5-1.2; P = 0.216). In addition, the risk of acute heart failure and 1-year major adverse cardiovascular events did not differ significantly between the groups. However, the median hydration duration was significantly shorter in the SH group than in the control group (6 vs 25 hours; P < 0.001). CONCLUSIONS In CKD patients undergoing CAG, SH is noninferior to standard hydration in preventing CA-AKI with a shorter hydration duration.

Abstract
BACKGROUND Previous meta-analyses of pulmonary arterial hypertension (PAH) combination therapy pooled sequential and initial combination together, which might threaten their authenticity and clinical significance for the difference between two strategies. METHODS PubMed, Embase, and the Cochrane Library were searched for randomized controlled trials (RCTs) that compared sequential combination therapy (SCT) with background therapy (BT) in PAH patients. Raw data were extracted to calculate risk ratio (RR) or weighted mean difference (WMD) for predefined efficacy and safety outcomes. Mantel-Haenszel fixed or random effects model was used based on heterogeneity. RESULTS 17 RCTs involving 4343 patients (97.2% of patients with WHO-FC II-III) were included. SCT decreased clinical worsening (RR 0.66, 95% CI 0.58 to 0.76), nonfatal clinical worsening (RR 0.61, 95% CI 0.52 to 0.71), functional class (decrease of 28% in the portion of patients with WHO-FC worsening and increase of 33% in the portion of patients with WHO-FC improvement), and increased 6-min walk distance (WMD 17.68 m, 95% CI 10.16 to 25.20), but didn't reduce mortality, lung transplantation, admission to hospital, and treatment escalation compared with BT. Although any adverse event and serious adverse event were similar between SCT and BT, SCT increased all-cause treatment discontinuation (RR 1.49, 95% CI 1.30 to 1.71) and drug-related treatment discontinuation (RR 2.30, 95% CI 1.86 to 2.84) with higher incidence of headache, flushing, nausea, diarrhoea and jaw pain. CONCLUSIONS For WHO-FC II-III PAH patients who have established BT, our study reinforced the recommendation of SCT to improve clinical worsening, functional status, and exercise capacity, although with higher incidence of side-effects and withdrawal.

Abstract
Objectives: To explore the efficacy and safety of emergency transcatheter aortic valve replacement (TAVR). Methods: Data of patients who underwent emergency TAVR in eight centers, namely Fuwai Hospital, Wuhan Asia Heart Hospital, Xijing Hospital, Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology, Guangdong Provincial People's Hospital, Zhongshan Hospital Affiliated to Fudan University, the First Affiliated Hospital of Zhengzhou University, the Second Xiangya Hospital of Central South University, between May 2017 and December 2020 were retrospectively analyzed. The use of mechanical circulatory support system (MCS) and the results of laboratory tests (N-terminal B-type natriuretic peptide (NT-proBNP)) and echocardiography (mean aortic valve cross valve pressure difference and left ventricular ejection fraction) before and after operation were collected. The primary endpoint was all-cause death, and the secondary endpoints were stroke, major bleeding, major vascular complications, myocardial infarction, permanent pacemaker implantation, and acute renal injury. Device success was caculated, which refered to absence of procedural mortality and correct positioning of a single prosthetic heart valve into the proper anatomical location and intended performance of the prosthetic heart valve (mean aortic valve gradient<20 mmHg(1 mmHg=0.133 kPa) or peak velocity<3 m/s, with no moderate or severe prosthetic valve regurgitation). Kaplan-Meier survival curve was used to estimate the survival rate of patients during follow-up. Results: This study included 48 patients. The age was (72.5±8.1) years, and 34 patients were males (70.8%). Device success rate was 91.7% (44/48). The mean aortic valve transvalvular pressure was significantly decreased after operation ((12.3±6.4)mmHg vs. (60.2±23.8)mmHg, P<0.000 1). Left ventricular ejection fraction was significantly increased ((41.5±11.7)% vs. (31.0±11.3)%, P<0.000 1). NT-proBNP significantly decreased (3 492.0 (1 638.8, 7 165.5) ng/L vs. 12 418.5 (6 693.8, 35 000.0) ng/L, P<0.000 1). In-hospital all-cause mortality was 8.3% (4/48). During hospitalization, the rate of stroke was 2.1% (1/48), major bleeding was 6.3% (3/48), major vascular complications was 10.4% (5/48), myocardial infarction was 4.2% (2/48), permanent pacemaker implantation was 6.3% (3/48), and the rate of acute renal injury was 12.5% (6/48). MCS was used in 20 patients (41.7%). The median follow-up time was 196 days. During the follow-up, one patient died (due to systemic metastasis of pancreatic cancer), two cases suffered new myocardial infarction and one case received permanent pacemaker implantation. The survival rate of 30 days, 1 year and 2 years after the operation were 91.7% (44/48), 89.6% (43/48), 89.6% (43/48), respectively. Conclusion: Emergency TAVR may be a safe and effective treatment for patients with severe decompensated aortic valve stenosis.

Abstract
Transcatheter closure (TCC) has emerged as the first-line treatment for coronary artery fistulas. However, limited data exist regarding the long-term outcomes and technical aspects of this procedure. We aimed to report the long-term outcomes and technical aspects of TCC of large coronary-cameral fistulas (CCFs).All patients with large CCFs who underwent attempted TCC using the patent ductus arteriosus (PDA) occluder or Amplatzer vascular plug (AVP), from June 2002 to December 2017, were retrospectively reviewed. A total of 23 patients with large CCFs underwent attempted TCC using the PDA occluder or AVP. Most CCFs originated from the right coronary artery and drained predominantly into the right heart chamber. Procedural success was achieved in 21 (91.3%) patients. Devices were deployed using the arteriovenous loop in 15, transarterial approach in 4, and arterio-artery loop approach in 2 patients. Procedural complications included coronary spasm in one and side branch occlusion in one patient. Among these 21 patients with successful device implantation, follow-up angiograms or computed tomography angiograms were obtained in 14 (66.7%) patients at a median of 11.0 (range, 9.8-16.3) months. Late complications included thrombosis of residual fistula segment without myocardial infarction (MI) in one, coronary thrombosis resulting in MI in one, and recanalization necessitating re-intervention in one patient. No death and device embolization occurred.TCC of large CCFs using the PDA occluder or AVP is an effective therapy in anatomically suitable candidates, with favorable long-term outcomes. Given that potentially hazardous complications may occur late after the procedure, long-term periodic evaluation is mandatory.

Abstract
BACKGROUND Patients with anterior acute myocardial infarction (AMI) and left ventricular (LV) dysfunction have an increased risk of LV thrombus (LVT). In the thrombolytic era, short-term anticoagulation using low-molecular-weight heparin during hospitalization proved to significantly reduce LVT formation, but, the effect of this prophylactic approach remains unclear in the current era. Therefore, we conducted a study to evaluate the effects of post-procedural anticoagulation (PPAC) using enoxaparin in addition to dual antiplatelet therapy (DAPT) after primary percutaneous coronary intervention (PCI) in such patients.Methods and Results:A total of 426 anterior AMI patients with LV ejection fraction ≤40% were retrospectively enrolled and classified into 2 groups based on whether they received PPAC (enoxaparin SC for at least 7 days). All patients received primary PCI and DAPT. The primary endpoint was definite LVT at 30 days diagnosed by echocardiography. The secondary endpoints were 30-day mortality, embolic events, and major bleeding events. PPAC was independently associated with a lower incidence of LVT (odds ratio 0.139, 95% confidence interval 0.032-0.606, P=0.009). The 30-day mortality, embolic events, and major bleeding events were not statistically different between groups. CONCLUSIONS Short-term PPAC using enoxaparin after primary PCI may be an effective and safe way to prevent LVT in patients with anterior AMI and LV dysfunction.

Abstract
Objective: To identify the characteristics including clinical features and pulmonary computed tomography (CT) features of heart failure and COVID-19. Methods: This study was a retrospective study. A total of 7 patients with heart failure and 12 patients with COVID-19 in the Second Xiangya Hospital of Central South University between December 1, 2019 and February 15, 2020 were enrolled. The baseline clinical and imaging features of the two groups were statistically analyzed. Results: There was no significant difference in age and sex between the two groups(both P>0.05), but the incidence of epidemiological contact history, fever or respiratory symptoms in the COVID-19 group was significantly higher than that in the heart failure group (12/12 vs. 0, P<0.001; 12/12 vs. 4/7, P=0.013). While the proportion of cardiovascular diseases and impaired cardiac function was significantly less than that of the heart failure group(2/12 vs.7/7, P<0.001;0 vs.7/7, P<0.001). For imaging features, both groups had ground-glass opacity and thickening of interlobular septum, but the ratio of central and gradient distribution was higher in patients with heart failure than that in patients with COVID-19 (4/7 vs. 1/12, P=0.04). In heart failure group, the ratio of the expansion of pulmonary veins was also higher (3/7 vs. 0,P=0.013), and the lung lesions can be significantly improved after effective anti-heart failure treatment. Besides, there were more cases with rounded morphology in COVID-19 group(9/12 vs. 2/7, P=0.048). Conclusions: More patients with COVID-19 have epidemiological history and fever or respiratory symptoms. There are significant differences in chest CT features, such as enlargement of pulmonary veins, lesions distribution and morphology between heart failure and COVID-19.

Abstract
BACKGROUND Admission electrocardiographic (ECG) findings of non-ST-segment elevation myocardial infarction (NSTEMI) include transient ST-segment elevation (TSTE), ST-segment depression (STD), T-wave inversion (TWI), and no ischemic changes (NIC). HYPOTHESIS This study aimed to assess the prognostic value of qualitative ECG findings at presentation and to clarify the influence of invasive treatment on the prognostic value of admission ECG findings. METHODS We analyzed the Acute Coronary Syndrome Quality Improvement in Kerala (ACS QUIK) study post hoc. NSTEMI patients were included and classified into four groups per ECG findings. Study endpoints were in-hospital and 30-day mortality rates and major adverse events (MAE). We performed multivariate logistic regression, adjusting for covariates in the Global Registry of Acute Coronary Events risk model, with subset analyses of patients treated with or without invasive management. RESULTS STD patients had significantly higher in-hospital and 30-day mortality rates/MAE than TWI patients, which had lower in-hospital mortality rate/MAE than the NIC group. TSTE patients had intermediate outcomes. In multivariate logistic regression using the TWI group as the reference, STD and NIC remained independently associated with worse outcomes. Subset analysis showed prognostic value of admission ECG in non-invasively managed but not in invasively managed patients. CONCLUSIONS STD was associated with adverse outcomes, TWI with benign prognoses. NIC should not be taken to indicate low risk. Qualitative analysis of admission ECG is suitable for rapid risk stratification of NSTMI patients at presentation. However, it may not be predictive of short-term outcomes of NSTEMI patients after invasive management.

Abstract
Sinus of Valsalva aneurysm, a rare cardiac anomaly, can be life-threatening if it ruptures. Transcatheter closure has emerged as an effective alternative to surgical management; however, it has rarely been reported in patients with previous mechanical aortic valve replacements. We describe the case of a 45-year-old man who presented with a ruptured aneurysm of the noncoronary sinus of Valsalva 14 years after the implantation of a mechanical aortic valve. The ruptured aneurysm was closed by transcatheter means with use of a double-disc perimembranous ventricular septal defect occluder. The patient remained asymptomatic one year after the procedure. Our case suggests that transcatheter closure with use of this type of occluder is a viable method for successfully repairing ruptured sinus of Valsalva aneurysms in patients who have mechanical aortic valves.

Abstract
Ventricular pseudoaneurysm (PSA) is a rare, yet life-threatening complication of myocardial infarction, cardiac surgery, and transcatheter valve replacement. Although conventional surgery is the preferred treatment strategy, transcatheter closure has emerged as an effective alternative in selected candidates. In this report, we describe successful transcatheter closure of two unique cases of ventricular pseudoaneurysm (PSA): first, a complex post-myocardial infarction left ventricular PSA (LVPSA) with multi-communications, and second, a case of post-traumatic right ventricular PSA (RVPSA) following blunt chest injury caused by domestic violence.

Abstract
BACKGROUND Postinfarction ventricular septal rupture (PI-VSR) is a rare but devastating complication of acute myocardial infarction (AMI). Risk stratification in the acute phase is crucial for decision-making, and this study analyzed the risk factors for early mortality and the effects of various management options on the outcome of PI-VSR patients in the era of percutaneous intervention. METHODS A total of 96 patients with PI-VSR were identified and divided into an acute-phase survivor group (n = 46, survived ≥2 weeks after admission) and a nonsurvivor group (n = 50, died within 2 weeks after admission). Percutaneous closure was considered in acute-phase survivors. Patients were followed up for a mean 47 (quartiles 15-71) months by clinical visit or telephone interview. RESULTS The overall acute-phase (i.e., < 2 weeks after the diagnosis of PI-VSR) mortality rate was 52%. Female sex and Killip Class III-IV at admission were associated with an increased risk of acute-phase death. Of the 46 patients who survived ≥2 weeks, 20 underwent interventional occlusion and the procedure was successful in 19. Percutaneous closure in the acute-phase survivor group improved the immediate (21% in-hospital mortality rate) and long-term (53% mortality) outcomes. CONCLUSIONS Patients with PI-VSR are at a high risk of acute-phase mortality. Female sex and severe cardiac dysfunction at admission are linked with a high rate of acute-phase deaths. Percutaneous closure in acute-phase survivors results in favorable short- and long-term benefits for PI-VSR patients.

Abstract
Background The association between metabolic syndrome (MS) and bladder cancer (BC) was not fully investigated, and most primary studies and pooled analyses were only focused on certain specific components. Objective To further investigate this issue and obtain more precise findings, we conducted this updated evidence synthesis of published studies, which involved not only MS components but also the MS in its entirety. Materials and methods We searched the PubMed, EMBASE, and Web of Science databases for observational studies on the association between BC susceptibility and/or mortality, and MS and its components. We extracted data from included studies, evaluated heterogeneity, and performed meta-analytic quantitative syntheses. Results A total of 95 studies with 97,795,299 subjects were included in the present study. According to the results, MS significantly increased the risk of BC (risk ratio [RR]=1.11, 95% CI=1.00–1.23); diabetes significantly increased the risk of BC (RR=1.29, 95% CI=1.19–1.39) and associated with poor survival (RR=1.24, 95% CI=1.08–1.43). Excessive body weight was associated with increased susceptibility (RR=1.07, 95% CI=1.02–1.12), recurrence (RR=1.46, 95% CI=1.18–1.81), and mortality (RR=1.17, 95% CI=1.00–1.37). As indicated by cumulative meta-analysis, sample size was inadequate for the association between BC susceptibility and MS, the association between BC recurrence and excessive body weight, and the association between BC survival and diabetes. The sample size of the meta-analysis was enough to reach a stable pooled effect for other associations. Conclusion Diabetes and excessive body weight as components of MS are associated with increased susceptibility and poor prognosis of BC. Uncertainty remains concerning the impact of overall MS, hypertension, and dyslipidemia on BC susceptibility and prognosis, for which further investigations are needed.

Abstract
This study was aimed at investigating the effects of lncRNA AK139328 on myocardial ischaemia/reperfusion injury (MIRI) in diabetic mice. Ischaemia/reperfusion (I/R) model was constructed in normal mice (NM) and diabetic mice (DM). Microarray analysis was utilized to identify lncRNA AK139328 overexpressed in DM after myocardial ischaemia/reperfusion (MI/R). RT‐qPCR assay was utilized to investigate the expressions of lncRNA AK139328 and miR‐204‐3p in cardiomyocyte and tissues. Left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), left ventricular ejection fraction (LVEF) and fractioning shortening (FS) were obtained by transthoracic echocardiography. Haematoxylin‐eosin (HE) staining and Masson staining were utilized to detect the damage of myocardial tissues degradation of myocardial fibres and integrity of myocardial collagen fibres. Evans Blue/TTC staining was used to determine the myocardial infarct size. TUNEL staining was utilized to investigate cardiomyocyte apoptosis. The targeted relationship between lncRNA AK139328 and miR‐204‐3p was confirmed by dual‐luciferase reporter gene assay. MTT assay was used for analysis of cardiomyocyte proliferation. Western blot was utilized to investigate the expression of alpha smooth muscle actin (α‐SMA), Atg7, Atg5, LC3‐II/LC3‐I and p62 marking autophagy. Knockdown of lncRNA AK139328 relieved myocardial ischaemia/reperfusion injury in DM and inhibited cardiomyocyte autophagy as well as apoptosis of DM. LncRNA AK139328 modulated miR‐204‐3p directly. MiR‐204‐3p and knockdown of lncRNA AK139328 relieved hypoxia/reoxygenation injury via inhibiting cardiomyocyte autophagy. Silencing lncRNA AK139328 significantly increased miR‐204‐3p expression and inhibited cardiomyocyte autophagy, thereby attenuating MIRI in DM.

Abstract
BACKGROUND Guide catheter extension systems have become one of the most powerful tools for address-ing complex lesions during percutaneous coronary intervention (PCI), but data on a new-generation rapid exchange extension catheter - the Guidezilla catheter - are limited. Summarized herein reports on experience using the Guidezilla catheter for complex coronary lesions via a transradial approach at the documented institution an evaluation of its safety and efficacy. METHODS A total of 25 patients (19 males and 6 females) who underwent PCI via the radial approach with the Guidezilla catheter for adequate back-up support and to facilitate equipment delivery were enrolled. The clinical, angiographic and procedural data of all 26 procedures in 25 patients (1 patient underwent two PCI procedures on different lesions) were collected to evaluate the safety and efficacy of this novel equipment. RESULTS The mean age of the enrolled patients was 67.7 ± 8.41 years old. The mean depth of intuba-tion was 27.90 ± 12.23 mm. Stent implantation was successful in 23 out of 26 procedures (88.5%) and failed in 3 cases: 1 case of tortuosity and severe angulation in a chronic total occlusion lesion; 1 case of an existing type B dissection (NHLBI classification system for coronary artery dissection types); and 1 case in which a stent was stripped off its balloon. None of the patients experienced coronary dissection, perforation, air embolism, pressure dampening or other major complications during the procedure. CONCLUSIONS The Guidezilla extension catheter is an effective and safe tool that provides improved back-up support and increases the success rate of PCI for complex coronary lesion by radial access.

Abstract
This study was to evaluate the effects of supplementation of AA form (crystalline vs. protein bound) in low-protein diets on growth, metabolic, and immunological characteristics of pigs. A total of 80 barrows (PIC 327 × 1050; 15.57 ± 0.13 kg BW and 48 ± 2 d of age), housed in 4 pigs per pen with 5 pens per treatment, were assigned to 4 dietary treatments of 17, 15, and 13% CP and 13% CP plus casein for 28 d. The crystalline AA were supplemented to meet the requirement of indispensable AA in pigs. Results showed that pigs fed the 13% CP diet or the 13% CP plus casein diet had lower ( < 0.01) ADG and ADFI and a greater ( < 0.01) feed:gain ratio than pigs fed the 17% CP or 15% CP diets over the 4-wk study period. Compared with other diets, pigs fed the 13% CP diet had decreased concentrations of plasma urea nitrogen, albumin ( < 0.01), and mRNA expressions of Toll-like receptor 4 (), nuclear factor kappa B (; < 0.05), and Toll-interacting protein (; < 0.01) in the ileum and also increased activity of plasma glutamate-pyruvate transaminase ( < 0.05) and concentrations of IL-1β ( < 0.05) and tumor necrosis factor-α ( < 0.01); however, these characteristics were partly normalized by feeding the 13% CP plus casein diet. Furthermore, the plasma concentration of insulin-like growth factor 1 (IGF-1; < 0.01) and mRNA expressions of protein kinase B (), mammalian target of rapamycin (), and ribosomal protein S6 kinase () in longissimus muscle were increased ( < 0.05) in pigs fed the 13% CP plus casein diet relative to pigs fed the 17% CP or 15% CP diets. In summary, reducing dietary CP level from 17% to 15% had no effect on growth, metabolic, and immunological characteristics of 15- to 35-kg pigs. A further reduction of dietary CP level up to 13% would lead to poor growth performance, but metabolic and immunological characteristics were partly normalized using protein-bound AA to replace synthesized AA in the 13% CP diet.

Abstract
BACKGROUND Acute aortic dissection is a life-threatening cardiovascular emergency. Pentraxin-3 (PTX3) is proposed as a prognostic marker and found to be related to worse clinical outcomes in various cardiovascular diseases. This study sought to investigate the association of circulating PTX3 levels with in-hospital mortality in patients with acute Type A aortic dissection (TAAD). METHODS A total of 98 patients with TAAD between January 2012 and December 2015 were enrolled in this study. Plasma concentrations of PTX3 were measured upon admission using a high-sensitivity enzyme-linked immunosorbent assay system. Patients were divided into two groups as patients died during hospitalization (Group 1) and those who survived (Group 2). The clinical, laboratory variables, and imaging findings were analyzed between the two groups, and predictors for in-hospital mortality were evaluated using multivariate analysis. RESULTS During the hospital stay, 32 (33%) patients died and 66 (67%) survived. The patients who died during hospitalization had significantly higher PTX3 levels on admission compared to those who survived. Pearson's correlation analysis demonstrated that PTX3 correlated positively with high-sensitivity C-reactive protein (hsCRP), maximum white blood cell count, and aortic diameter. Multivariate logistic regression analysis demonstrated that PTX3 levels, coronary involvement, cardiac tamponade, and a conservative treatment strategy are significant independent predictors of in-hospital mortality in patients with TAAD. The receiver operating characteristic curve analysis further illustrated that PTX3 levels on admission were strong predictors of mortality with an area under the curve of 0.89. A PTX3 level ≥5.46 ng/ml showed a sensitivity of 88% and a specificity of 79%, and an hsCRP concentration ≥9.5 mg/L had a sensitivity of 80% and a specificity of 69% for predicting in-hospital mortality. CONCLUSION High PTX3 levels on admission are independently associated with the in-hospital mortality in patients with TAAD.

Abstract
Traumatic ventricular septal defect (VSD) resulting from chest trauma, either penetrating or blunt, is a relatively rare occurrence. Herein, we describe the case of a previously healthy 26-year-old man who presented with congestive heart failure, which was secondary to a large traumatic VSD following violent blunt chest trauma. The traumatic VSD was initially closed percutaneously using an Amplatzer atrial septal defect occluder. Post-device closure, however, the patient developed severe intravascular hemolysis refractory to medical treatment. The patient subsequently underwent surgical removal of the Amplatzer device, with concomitant VSD patch closure.

Abstract
This experiment was conducted to investigate the effects of inulin supplementation in low- or high-fat diets on both the reproductive performance of sow and the antioxidant defence capacity in sows and offspring. Sixty Landrace × Yorkshire sows were randomly allocated to four treatments with low-fat diet (L), low-fat diet containing 1.5% inulin (LI), high-fat diet (H) and high-fat diet containing 1.5% inulin (HI). Inulin-rich diets lowered the within-litter birth weight coefficient of variation (CV, p = 0.05) of piglets, increased the proportion of piglets weighing 1.0-1.5 kg at farrowing (p < 0.01), reduced the loss of body weight (BW) and backfat thickness (BF) during lactation (p < 0.05) and decreased the duration of farrowing as well as improved sow constipation (p < 0.05). Sows fed fat-rich diets gained more BW during gestation (p < 0.01), farrowed a greater number of total (+1.65 pigs, p < 0.05) and alive (+1.52 pigs p < 0.05) piglets and had a heavier (+2.06 kg, p < 0.05) litter weight at birth as well as a decreased weaning-to-oestrous interval (WEI, p < 0.01) compared with sows fed low-fat diets. However, it is worth noting that the H diet significantly decreased the serum activities of superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-Px) and increased the serum malondialdehyde (MDA) levels in sows and piglets (p < 0.05). In contrast, HI diet enhanced the activities of T-SOD and GSH-Px and decreased the serum MDA concentrations (p < 0.05) in sows and piglets. In summary, the fat-rich diets fed to sows during gestation had beneficial effects on reproductive performance, but aggravated the oxidative stress in sow and piglets. Inulin-rich diets fed to sow during gestation had beneficial effects on within-litter uniformity of piglet birthweight and enhanced the antioxidant defence capacity of sows and piglets.

Abstract
The effects of dietary β-hydroxy-β-methylbutyrate (HMB) supplementation during gestation on reproductive performance of sows and the mRNA expression of myogenic markers in skeletal muscle of neonatal pigs were determined. At day 35 of gestation, a total of 20 sows (Landrace × Yorkshire, at third parity) were randomly assigned to two groups, with each group receiving either a basal diet or the same diet supplemented with 4 g/day β-hydroxy-β-methylbutyrate calcium (HMB-Ca) until parturition. At parturition, the total and live litter size were not markedly different between treatments, however, the sows fed HMB diet had a decreased rate of stillborn piglets compared with the sows fed the control (CON) diets (p < 0.05). In addition, piglets from the sows fed HMB diet tended to have an increased birth weight (p = 0.08), and a reduced rate of low birth weight piglets (p = 0.05) compared with piglets from the CON sows. Nevertheless, lower feed intake during lactation was observed in the sows fed the HMB diet compared with those on the CON diet (p < 0.01). The relative weights of the longissimus dorsi (LD) and semitendinosus (ST) muscle were higher (p < 0.05) in neonatal pigs from the HMB than the CON sows. Furthermore, maternal HMB treatment increased the mRNA levels of the myogenic genes, including muscle regulatory factor-4 (MRF4, p < 0.05), myogenic differentiation factor (MyoD) and insulin-like growth factor-1 (IGF-1, p < 0.01). In conclusion, dietary HMB supplementation to sows at 4 g/day from day 35 of gestation to term significantly improves pregnancy outcomes and increases the expression of myogenic genes in skeletal muscle of neonatal piglets, but reduces feed intake of sows during lactation.

Abstract
This study sought to investigate the association of baseline serum cystatin C levels with myocardial perfusion and cardiac functional recovery in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). 108 patients with a first anterior STEMI who underwent PPCI were enrolled. Serum cystatin C was measured by immunoturbidimetric method. Patients were divided into two groups according to the median cystatin C levels on admission: group 1 (≥median, n = 54) and group 2 (<median, n = 54). Myocardial perfusion was assessed by angiographic criteria, ST-segment resolution, and the index of microcirculatory resistance (IMR). Echocardiographic wall motion score index was analyzed on admission and at 6-month follow-up. Patients with angiographically, electrocardiographically no-reflow had significantly higher cystatin C levels on admission. Patients with an IMR ≥33.7 U also had significantly higher cystatin C levels. The WMSI showed a greater improvement in group 2 than in group 1 and there was a significant negative correlation between improvement of WMSI and the cystatin C levels. There was no significant difference in MACEs between the 2 groups. However, congestive heart failure (CHF) was observed significantly more frequent in group 1 than in group 2 (18.5 vs. 5.6 %, p = 0.022). Multivariate logistic regression analysis demonstrated that cystatin C levels at admission were a significant independent predictor of angiographic no-reflow and the development of CHF at 6-month follow-up. Elevated cystatin C levels at admission were independently associated with impaired myocardial perfusion, poor cardiac functional recovery and development of CHF in patients with anterior STEMI undergoing PPCI.

Abstract
BACKGROUND Transcatheter closure (TCC) of ruptured sinus of Valsalva aneurysm (RSVA) is an alternative strategy to surgery, but there is a lack of long-term outcome data. METHODS AND RESULTS: From 2004 to 2012, 17 patients (8 males, 9 females) were treated with patent ductus arteriosus (PDA) occluders by antegrade venous approach and were followed for 18-102 months. Of the 17 patients, transthoracic echocardiography revealed rupture of the right coronary sinus into the right ventricle in 9 and into the right atrium in 4, and noncoronary sinus rupture into the right ventricle in 3 and into the right atrium in 1. Most (10/17) were in New York Heart Association (NYHA) functional class III or IV. Aortography showed that the size of the defect was 7.71±2.84 mm (4-15 mm). TCC was attempted using PDA occluders 2-5 mm larger than the aortic end of the defects. The device sizes ranged from 8/6 to 18/16 mm (median, 10/8 mm). The procedure was successful in 16 (94.1%), and all of them had complete occlusion at discharge. On a median follow-up of 42 months, 14 patients were in NYHA class I and 2 were in class II, and there was no residual shunt, device embolization, infective endocarditis, or aortic regurgitation. CONCLUSIONS TCC of RSVA is a safe and effective alternative to surgery with favorable long-term follow-up results.

Abstract
BACKGROUND The aim of this research was to study whether transplantation of mesenchymal stem cells (MSCs) overexpressing microRNA-1 into mouse infarcted myocardium can enhance cardiac myocyte differentiation and improve cardiac function efficiently. METHODS Eight-week-old female C57BL/6 mice underwent ligation of the left coronary artery to produce models of myocardial infarction. The ligated animals were randomly divided into 4 groups (20 in each). One week later, they were intramyocardially injected at the heart infarcted zone with microRNA-1-transduced MSCs (MSC(miR-1) group), mock-vector-transduced MSCs (MSC(null) group), MSCs (MSC group) or medium (PBS group). At 4 weeks post-transplantation, transthoracic echocardiographic assessment, histological evaluation and Western blot were performed. RESULTS The transplanted MSCs were able to differentiate into cardiomyocytes in the infarcted zone. Cardiac function in the MSC, MSC(null) and MSC(miR-1) groups was significantly improved compared to the PBS group (p < 0.01 or p < 0.001). However, treatment of MSCs expressing microRNA-1 was more effective for cardiac repair and improved cardiac function more efficiently by enhancing cell survival and cardiac myocyte differentiation compared to the MSC group or the MSC(null) groups (p < 0.05 or p < 0.01, respectively). CONCLUSIONS Transplantation of microRNA-1-transfected MSCs was more conducive to repair of infarct injury and improved heart function by enhancing transplanted cells survival and cardiomyogenic differentiation.

Abstract
BACKGROUND Transcatheter closure is an effective approach for perimembranous ventricular septal defects (PMVSD). However, atrioventricular blocks (AVB) emerged possibly due to the close proximity of the PMVSD to the conduction system, but concern for the complication was not adequately emphasized. In this study, we report the incidence of AVBs, in and after transcatheter closure of a PMVSD, and the outcome of the complication in our center. METHODS One hundred and sixty-eight PMVSD patients were accepted for transcatheter closure with Amplazter PMVSD occluder (AGA Medical, Plymouth, Minn., USA). The procedure was discontinued when a second- or third-degree AVB occurred. A steroid was administered to all patients who developed AVBs. Temporary pacemakers were inserted in patients who developed a complete AVB or Mobitz type II AVB during or after the procedure. RESULTS During the follow-up period of 6-24 mo (mean 10.6 +/- 3.9), the incidence of AVBs occurring during or after transcatheter closure of PMVSD was 3.5%. The AVB disappeared quickly after discontinuing the procedure in patients who developed AVBs during the procedure, whereas the AVBs disappeared between 2 and 21 d (mean 8.0 +/- 8.8) in the patients who developed AVBs after the procedure. However, complete right bundle branch block (CRBBB) was observed, and a transient complete AVB emerged after 8 mo in 1 case, incomplete right bundle branch block (IRBBB) in 1 case, and CRBBB and left anterior hemiblock (LAH) in 1 case. CONCLUSIONS The AVB is a serious complication during and after transcathter closure of PMVSD. More attention should be paid to the complication, and multicentres are required to monitor the complication.

Abstract
BACKGROUND Bone morphogenetic protein-2 (BMP-2) plays a key role both in vascular development and pathophysiological processes. However, the effects of oxidized low-density lipoprotein (ox-LDL) combined with atorvastatin on BMP-2 expression are entirely unknown in human umbilical vein endothelial cells (HUVECs). The present study investigates the effects of ox-LDL on BMP-2 expression. Furthermore, the influence of atorvastatin on ox-LDL-induced BMP-2 expression is also examined. METHODS AND RESULTS The HUVECs were treated by ox-LDL or combined with pyrrolidine dithiocarbamate (PDTC) or atorvastatin. The expression level of BMP-2 mRNA was examined by real-time PCR and RT-PCR analysis. The expression of BMP-2 protein was assayed by enzyme-linked immunosorbent assay. The malondialdehyde (MDA) and activities of total superoxide dismutase (SOD) were detected by routine methods. The activation of nuclear factor kappaB (NF-kappaB) in HUVECs was determined using an assay kit from active motif and western blot analysis. Ox-LDL treatment significantly increased BMP-2 expression, which is associated with NF-kappaB activation, but BMP-2 expression was suppressed by treatment with PDTC or atorvastatin. Furthermore, the increase in MDA levels and decrease in activities of total SOD caused by ox-LDL treatment were reversed by the treatment of PDTC or atorvastatin. CONCLUSIONS Ox-LDL-induced BMP-2 expression was suppressed by PDTC or atorvastatin treatment. The effects of atorvastatin might contribute to the mechanisms by inhibiting NF-kappaB activation.

Abstract
An in vitro and a feeding trial was conducted to investigate the effect of fibre-degrading enzymes A (xylanase + β-glucanase), B (xylanase) and C (xylanase + cellulase) on the nutritive value of broiler diets containing either hulled (22.5% and 23.5% for 4–21 days and 22–42 days of age, respectively) or dehulled (20% and 21.5%) Chinese double-low rapeseed meals (DLRM). Overall, in vitro digestibility of dry matter (DM) or neutral digestibility fibre (NDF) did not differ (p > 0.05) because of meal types; both crude protein (CP) and NDF digestibility was improved (p < 0.05) because of addition of enzymes B or C either to hulled or dehulled DLRM diets. Birds fed dehulled DLRM diets had a higher (p < 0.05) growth rate, feed efficiency and lower (p < 0.05) feed intake than those fed hulled DLRM diets during the overall phase. Enzyme C addition to dehulled DLRM diets resulted in improved (p < 0.05) growth rate and feed efficiency during 4–21 days of age. Enzymes A and B addition elicited a positive response in feed intake and weight gain (p < 0.05), respectively, but did not affect (p > 0.05) feed efficiency. It would appear that the nutritive value of broiler diets containing Chinese DLRM could be improved by appropriate xylanase-based enzymes. Responses of broilers to fibre-degrading enzymes could be highlighted by hull removal of fed DLRM.

Abstract
This study was conducted to investigate the effect of two distinct enzyme preparations on nutrients' digestibility and growth performance of growing pigs fed diets based on corn, soya bean meal and Chinese double-low rapeseed meal (DLRM). The two enzyme preparations were Enzyme R, a preparation extracted from fermentation of a non-GMO fungus Penicillum funiculosum, developed for multi-grain and multi-animal species; and Enzyme P, a xylanase preparation from Trichoderma longibrachiatum, for pigs fed corn-based diets only. Both enzymes were tested at 0, 0.25 and 0.50 g/kg feed using 70 crossbred male pigs (Large Yorkshire x Landrace) in five dietary treatments and seven replicates in each treatment, for growth period from 27 to 68 kg live weight in 49 days. Results showed that the supplementation of both enzymes (1) increased total-tract digestibility of dietary energy from 77.5% (control) to 81.4% (Enzyme R, p < 0.05) and 81.9% (Enzyme P, p < 0.05); of neutral detergent fibre from 41.0% (control) to 57.8% (Enzyme R, p < 0.05) and 60.0% (Enzyme P, p < 0.05); (2) improved average daily gain from 786 g (control) to 829 g (Enzyme R, p < 0.05) and 846 g (Enzyme P, p < 0.05); and numerical increases in feed intake from 1.96 kg/pig/day (control) to 2.01 (Enzyme R) and 2.00 (p > 0.05) and feed conversion ratio from 2.50 (control) to 2.42 (Enzyme R) and 2.36 (Enzyme P, p < 0.05); (3) there was a dose response but no significant differences were observed in enzyme efficacy between the two enzyme preparations. The present study demonstrated beneficial effects of applying xylanase-based enzymes to improve feeding values of pig diets based on corn, soya bean meal and DLRM.

Abstract
OBJECTIVE To compare the success rate and the complication rate of immediate percutaneous coronary intervention (PCI) and elective PCI after coronary angiography(CAG), and to estimate the clinical value of immediate PCI. METHODS One-hundred fifteen patients who underwent immediate PCI after CAG were enrolled into the immediate group, and 172 patients on whom PCI and CAG were performed on 2 days were enrolled into the elective group in Second Xiangya Hospital of Central South University during 2005. The clinical manifestations, lesion vessel characteristics, and length and diameter of stents in the 2 groups were similar. Lesion vessels were defined as Type A, B, and C according to the standard of ACC/AHA in 1988. RESULTS The success rate and the complication rate of Type A and B lesion were not significantly different in the 2 groups (P>0.05). The success rate of Type C lesion in the immediate group was lower than that in the elective group (P<0.01). The complication rate of Type C lesion in the immediate group was higher than that in the elective group (P<0.05). CONCLUSION Type A and B lesions may undergo immediate PCI, while Type C lesion is not suitable to be performed immediately PCI after CAG. Immediate PCI after CAG has some clinical value.

Abstract
OBJECTIVE To explore the cause, the clinical manifestation and the management of peripheral vascular complications after cardiac catheterization. METHODS Clinical data of patients with peripheral vascular complications were analyzed retrospectively. RESULTS Of the 4,531 patients, 122 (2.7%) had peripheral vascular complications, including local hematoma (86 cases, 1.90%), pseudoaneurysm (15 cases, 0.33%), arteriovenous fistula (8 cases, 0.18%), femoral venous thrombosis (5 cases, 0.11%), excessive hemorrhage (5 cases, 0.11%), femoral arterial thrombosis (2 cases, 0.04%), and femoral nerve malfunction (1 case, 0.02%). All complications were relieved after conservative therapy except that one case needed surgery. CONCLUSION Peripheral vascular complications are associated with anticoagulation, diabetes, and hypertension. Prognosis of overwhelming complications is good, as long as patients are treated timely and appropriately.

Abstract
A short chain poly(acrylamide-dimethylacrylamide) (PADMA) was synthesized in aqueous phase using isopropanol as a chain transfer agent, and was characterized according to the chemical composition and molecular mass. This polymer can form a stable dynamic coating on the inner surface of the capillary, thereby suppressing the electroosmotic flow and DNA-capillary wall interaction. The sieving medium has low viscosity and capillary filling with this medium and medium replacement were conveniently carried out by commercial capillary electrophoresis instruments. The effects of components and concentration of copolymers on the separation of DNA fragments were investigated. Highly efficient separation of DNA fragments, successful single strand conformation polymorphism (SSCP) analysis and good reproducibility of the migration time were obtained in bare capillaries using these copolymers as sieving media. Our preliminary results demonstrate that PADMA will become an alternative matrix for DNA separation by capillary electrophoresis.
