    Abstract: Cerebral palsy (CP) is a neurodevelopmental disorder caused by a brain injury resulting in poor coordination and motor control deficits, which is one of the most common physical disabilities in children. CP brings a heavy burden on families and society and becomes a significant public health issue. In recent years, hydrotherapy, and transcranial direct current stimulation (tDCS) as a physical therapy for CP is developing rapidly. When hydrotherapy and tDCS are used to treat separately, it has positive therapeutic effect in children with CP. The development of new therapies in combination with physical rehabilitation approaches is critical to optimize functional outcomes. tDCS has attracted interest in this context, because of significant functional improvements have been demonstrated in individuals with brain injuries after a short period of cerebral stimulation. Since the onset of this work, tDCS has been used in combination with constraint-induced therapy, virtual reality therapy to potentiate the treatment effect. Up to now, there are no studies on the effect of a combined application of hydrotherapy and tDCS in children with CP. We will conduct a 2-arm parallel clinical trial to investigate the effect of a combined application of tDCS and hydrotherapy. Methods and analysis: This study is an outcome assessor and data analyst-blinded, randomized, controlled superiority trial during the period from October 2021 to December 2023. CP patients meeting the inclusion criteria will be allocated in a 1:1 ratio into the treatment group (hydrotherapy plus tDCS), or the control group (treatment as usual). All participants will receive 30 sessions of treatment over 10 weeks. The primary outcomes will be the difference in the Gross Motor Function Assessment and Pediatric Balance Scale during rest and activity. The secondary outcomes will be the difference in adverse effects between the control and treatment groups. Conclusions: This study aims to estimate the efficacy of a combined application of tDCS and hydrotherapy in patients with CP. Trial Registration: This study protocol was registered in Chinese ClinicalTrials.gov, ID: ChiCTR2100047946.

    Abstract: Hyperglycemia during acute myocardial infarction is common and associated with increased mortality. Thioredoxin-interacting protein (Txnip) is a modulator of cellular redox state and contributes to cell apoptosis. This study aimed to investigate whether hyperglycemia enhances Txnip expression and consequently exacerbates myocardial ischemia/reperfusion (MI/R) injury. Adult male SD rats were subjected to MI/R (30 min/4 h) and treated with saline or high glucose (HG, 500 g/L, 4 ml/kg/h, intravenously throughout the whole MI/R). In vitro study was performed on cultured neonatal rat cardiomyocytes subjected to simulated ischemia/reperfusion (SI/R) and incubated with HG (25 mM) or normal glucose (5.6 mM) medium. In vivo HG infusion significantly reduced the ± LV d P /dt max by 13.2 and 14.1% respectively (n=8, P 〈 0.05), increased infarct size and myocardial apoptosis ( P 〈 0.05) and increased superoxide accumulation ( P 〈 0.01) compared with those in the saline group. Meanwhile, Txnip expression was enhanced (Ratio of Txnip/β-actin: 1.22 ± 0.16 vs. 0.92 ± 0.05 of MI/R+saline, n=6-8, P 〈 0.05) whereas thioredoxin activity was inhibited (0.50 ± 0.05 vs. 1.41 ± 0.06 μmol/min/mg protein, P 〈 0.01) following HG treatment in MI/R hearts. Additionally, HG significantly activated p38 MAPK and inhibited Akt in I/R hearts ( P 〈 0.05). In cultured cardiomyocytes subjected to SI/R, HG incubation stimulated Txnip expression and reduced thioredoxin activity (n=6, P 〈 0.05). Overexpression of Txnip enhanced HG-induced superoxide generation and aggravated cell apoptosis (n=6, P 〈 0.05), while Txnip RNAi significantly blunted the deleterious effects of HG ( P 〈 0.05). Moreover, inhibition of p38 MAPK or activation of Akt markedly blocked HG-induced Txnip expression in I/R cardiomyocytes. Most importantly, intramyocardial injection of Txnip siRNA markedly decreased Txnip expression and alleviated MI/R injury as evidenced by reduced infarction size (23.7 ± 1.6% vs. 43.1 ± 4.8%, n=6, P 〈 0.05) and caspase 3 activity ( P 〈 0.05) in HG-treated rats. Hyperglycemia enhances myocardial Txnip expression, possibly through reciprocally modulating p38 MAPK and Akt activation, leading to aggravated oxidative stress and subsequent amplification of cardiac injury following MI/R.

    Abstract: Diabetes mellitus (DM) increases morbidity/mortality of ischemic heart disease (IHD). Although atrial natriuretic peptide (ANP) and C-type natriuretic peptide (CNP) reduce the myocardial ischemia/reperfusion (MI/R) damage in non-diabetic rats, whether vasonatrin peptide (VNP), the artificial synthetic chimera of ANP and CNP, confers cardioprotective effect against acute MI/R injury, especially in diabetic patients, is still unclear. This study aimed to investigate the effects of VNP on MI/R injury in diabetic rats and the involved mechanisms. The high-fat diet-fed streptozotocin (HFD-STZ) induced diabetic rats were subjected to MI/R (30 min/4 h). VNP treatment (100 µg/kg, i.v., 10 min before R) significantly improved ± LV d P /dt max [(3242 ± 103) and -(2731 ± 79) mm Hg/s vs. (2936 ± 90) and -(2422 ± 83) mm Hg/s in DM group] and LVSP and reduced LVEDP, and reduced infarct size [(43.3 ± 3.6) % vs (53.5 ± 2.8) %] , apoptosis index [(36.0 ± 2.1) % vs. (45.7 ± 3.5) %], caspase-3 activity, serum CK and LDH levels (n=8, P 〈 0.05). Moreover, VNP inhibited endoplasmic reticulum (ER) stress by suppressing GRP78 and CHOP (n=3, P 〈 0.05), and consequently increased the antiapoptotic protein Akt and ERK1/2 expression and phosphorylation levels ( P 〈 0.05). These effects were mimicked by 8-Br-cGMP (1 mg/kg, i.p., 20 min before R), a cGMP analogue, whereas inhibited by KT-5823 (0.5 mg/kg, i.p.), the selective inhibitor of PKG (both P 〈 0.05). In addition, pretreated DM rats with TUDCA (50 mg/kg, i.p.), a specific inhibitor of ER stress, couldn’t further promote the VNP’s cardioprotective effect ( P 〉 0.05). In vitro study was performed using H9c2 cardiomyocytes subjected to hypoxia/reoxygenation (H/R, 3 h/6 h) and incubated with or without VNP (10 -8 mol/L). Gene knockdown of PKG1α with siRNA blunted VNP’s inhibition of ER stress and apoptosis (n=6, P 〈 0.05), while overexpression of PKG1α resulted in significant decreased ER stress and apoptosis (n=6, P 〈 0.01). In conclusion, VNP protects diabetic heart against MI/R injury by inhibiting ER stress via cGMP-PKG signaling pathway. These results suggest that VNP may have potential therapeutic value for the diabetic patients with ischemic heart disease.

    Abstract: Treatment of coronary bifurcation lesions remains challenging; a simple strategy has been preferred as of late, but the disadvantage is ostium stenosis or even occlusion of the side branch (SB). Only a few single-center studies investigating the combination of a drug-eluting stent in the main branch followed by a drug-eluting balloon in the SB have been reported. This prospective, multicenter, randomized study aimed to investigate the safety and efficacy of a paclitaxel-eluting balloon (PEB) compared with regular balloon angioplasty (BA) in the treatment of non-left main coronary artery bifurcation lesions. Methods Between December 2014 and November 2015, a total of 222 consecutive patients with bifurcation lesions were enrolled in this study at ten Chinese centers. Patients were randomly allocated at a 1:1 ratio to a PEB group ( n  = 113) and a BA group ( n  = 109). The primary efficacy endpoint was angiographic target lesion stenosis at 9 months. Secondary efficacy and safety endpoints included target lesion revascularization, target vessel revascularization, target lesion failure, major adverse cardiac and cerebral events (MACCEs), all-cause death, cardiac death, non-fatal myocardial infarction, and thrombosis in target lesions. The main analyses performed in this clinical trial included case shedding analysis, base-value equilibrium analysis, effectiveness analysis, and safety analysis. SAS version 9.4 was used for the statistical analyses. Results At the 9-month angiographic follow-up, the difference in the primary efficacy endpoint of target lesion stenosis between the PEB (28.7% ± 18.7%) and BA groups (40.0% ± 19.0%) was –11.3% (95% confidence interval: –16.3% to –6.3%, P superiority 〈 0.0001) in the intention-to-treat analysis, and similar results were recorded in the per-protocol analysis, demonstrating the superiority of PEB to BA. Late lumen loss was significantly lower in the PEB group than in the BA group (–0.06 ± 0.32 vs . 0.18 ± 0.34 mm, P   〈  0.0001). For intention-to-treat, there were no significant differences between PEB and BA in the 9-month percentages of MACCEs (0.9% vs . 3.7%, P  = 0.16) or non-fatal myocardial infarctions (0 vs . 0.9%, P  = 0.49). There were no clinical events of target lesion revascularization, target vessel revascularization, target lesion failure, all-cause death, cardiac death or target lesion thrombosis in either group. Conclusions In de novo non-left main coronary artery bifurcations treated with provisional T stenting, SB dilation with the PEB group demonstrated better angiographic results than treatment with regular BA at the 9-month follow-up in terms of reduced target lesion stenosis.

    Abstract: Idiopathic ventricular tachycardia (VT) occurs in structurally normal hearts and accounts for a significant number of all types of VT. The genome-wide association study is the most effective strategy for identifying novel genetic variants for common diseases. However, no genome-wide association study has been reported for idiopathic VT. Methods: We conducted the first genome-wide association study for idiopathic VT in the Chinese Han population using a discovery population with 246 cases and 648 controls and a replication population with 222 cases and 〉 4072 controls. Candidate VT genes were functionally characterized in zebrafish. Real-time RT-PCR analysis was used to determine the effects of candidate genes on expression of ion channels and regulators. Patch-clamping was used to record L-type calcium current from neonatal rat cardiomyocytes with overexpression of candidate genes. Results: We identified 4 significant loci represented by rs78960694 (minor allele frequency [MAF]=5.02% in cases and 1.84% in controls; P =4.30×10 − 12, odds ratio [OR]=3.91) and rs2229095 (MAF=3.25% in cases and 1.63% in controls; P =1.02×10 − 7, OR=3.44) near and in CCR7 , respectively, rs68126098 in NELL1 (MAF=40.98% in cases and 32.07% in controls; P= 2.40×10 − 8, OR=1.53), rs2390325 between PKN2 and LMO4 (MAF=21.19% in cases and 15.12% in controls; P =1.92×10 − 7, OR=1.62), and rs270065 in CSMD1 (MAF=33.63% in cases and 40.25% in controls; P =9.51×10 − 7, OR=0.69). Note that the associations of idiopathic VT for CCR7 variant rs78960694 and NELL1 variant rs68126098 reach genome-wide significance ( P 〈 5.00×10 − 8). Overexpression of either PKN2 or CCR7 increased the heart rate in zebrafish, and enhanced expression of CACNA1C, RYR2 , or NOS1AP in zebrafish embryos, HEK293, and AC16 cardiomyocytes. Overexpression of either PKN2 or CCR7 significantly increased L-type Ca2+ current density. Conclusions: The first genome-wide association study identifies 4 novel loci and 2 risk genes ( PKN2 and CCR7 ) for idiopathic VT. These findings identify new molecular determinants for cardiac calcium homeostasis and rhythm maintenance and provide novel targets for diagnosis and treatment for idiopathic VT.
