Abstract
Objective: To investigate the short-term efficacy and safety of cardiac contractility modulation (CCM) in patients with heart failure. Methods: This was a cross-sectional study of patients with heart failure who underwent CCM placement at the First Affiliated Hospital of Xinjiang Medical University from February to June 2022. With a follow-up of 3 months, CCM sensation, impedance, percent output, and work time were monitored, and patients were compared with pre-and 3-month postoperative left ventricular ejection fraction (LVEF) values, and 6-minute walk test distance and New York Heart Association (NYHA) cardiac function classification, and the occurrence of complications was recorded. Results: CCM was successfully implanted in all 9 patients. Seven(7/9) of them were male, aged (56±14) years, 3 patients had ischaemic cardiomyopathy and 6 patients had dilated cardiomyopathy. At 3-month postoperative follow-up, threshold was stable, sense was significantly lower at follow-up than before (right ventricle: (16.3±7.0) mV vs. (8.2±1.1) mV, P<0.05; local sense: (15.7±4.9) mV vs. (6.7±2.5) mV, P<0.05), and impedance was significantly lower at follow-up than before (right ventricle (846±179) Ω vs. (470±65) Ω, P<0.05, local sense: (832±246) Ω vs. (464±63) Ω, P<0.05). The CCM output percentage was (86.9±10.7) %, the output amplitude was (6.7±0.4) V, and the daily operating time was (8.6±1.0) h. LVEF was elevated compared to preoperative ((29.4±5.2) % vs. (38.3±4.3) %, P<0.05), the 6-minute walk test was significantly longer than before ((96.8±66.7)m vs. (289.3±121.7)m, P<0.05). No significant increase in the number of NYHA Class Ⅲ-Ⅳ patients was seen (7/9 vs. 2/9, P>0.05). The patient was not re-hospitalised for worsening heart failure symptoms, had no malignant arrhythmic events and experienced significant relief of symptoms such as chest tightness and shortness of breath. No postoperative complications related to pocket hematoma, pocket infection and rupture, electrode detachment, valve function impairment, pericardial effusion, or cardiac perforation were found. Conclusions: CCM has better short-term safety and efficacy in patients with heart failure.

Abstract
Objective: To investigate the association between abnormal left atrial appendage function and thrombotic events in patients with non-valvular atrial fibrillation, and the independent risk factors affecting left atrial appendage function. Methods: Patients with non-valvular atrial fibrillation, who visited the Atrial Fibrillation Center of the First Affiliated Hospital of Xinjiang Medical University from June 1, 2019 to June 1, 2021, were selected. According to left atrial appendage flow velocity (LAAFV), they were divided into normal left atrial appendage function group (297 patients with LAAFV ≥ 40 cm/s) and abnormal left atrial appendage function group (85 patients with LAAFV<40 cm/s). Baseline data and transesophageal echocardiography images were collected from all the patients. The occurrence of thrombotic events was recorded. Univariate and multivariate unconditional logistic regression analyses were conducted to investigate the correlation between abnormal left atrial appendage function and the occurrence of thrombotic events. Results: There were significant differences in gender, type of atrial fibrillation, CHA2DS2-VASc score, anticoagulant therapy, total cholesterol, low-density lipoprotein cholesterol, international normalized ratio (INR), left atrial diameter, proportion of patients with right atrial enlargement, left ventricular ejection fraction, inner diameter, sum of inner diameter, depth, and sum of depth of all angles of the left atrial appendage, and incidence of thrombotic events between the two groups (all P<0.05). After adjusting for confounders, multivariate unconditional logistic regression analyses showed that abnormal left atrial appendage function was closely associated with thrombotic events (β=1.168 P=0.002), and left atrial diameter (OR=1.084, 95%CI 1.019-1.153, P=0.011) and persistent atrial fibrillation (OR=2.323, 95%CI 1.226-4.403, P=0.010) were independent risk factors affecting left atrial appendage function. Conclusions: Abnormal left atrial appendage function is closely associated with thrombosis. The left atrial diameter and persistent atrial fibrillation were independent risk factors affecting left atrial appendage function.

Abstract
BACKGROUND Unlike other IL-17 family members, the Th2-derived cytokine IL-25 (IL-17E) induces (promotes) Th2 responses. One or both of the two receptors for IL-25 (IL-17RA, IL-17RB) is expressed on inflammatory cells and tissue structural cells, suggesting that in addition to promoting Th2-type inflammation IL-25 may also act on structural cells at sites of Th2-type inflammation such as in the asthmatic bronchial mucosa to promote remodelling changes. OBJECTIVE Our previous studies showed elevated expression of IL-25 and IL-17RB immunoreactivity in asthmatic airways with co-localization of the latter to endothelial cells. We therefore hypothesized that IL-25 acts on endothelial cells through this receptor to induce production of the key angiogenic and remodelling cytokine basic fibroblast growth factor (bFGF). METHODS Polymerase chain reaction (PCR) immunocytochemistry/immunohistochemistry and ELISA were employed to detect expression of IL-17RB, IL-17RA and bFGF by human vascular endothelial cells (HUVEC) and immunoreactivity for IL-25 and bFGF in asthmatic bronchial biopsies. Receptor-blocking antibodies, PCR and an in vitro angiogenesis assay were used to investigate whether IL-25 acts on IL-17RB or IL-17RA to induce bFGF expression and angiogenesis. PCR was also employed to investigate the signalling pathways involved in IL-25-mediated bFGF expression. RESULTS HUVEC constitutively expressed IL-17RB, IL-17RA and bFGF. Production of the latter was further increased by IL-25, but attenuated after blockade of the IL-17RB, but not the IL-17RA receptor. Neutralization of endogenous VEGF and bFGF completely abrogated IL-25-induced angiogenesis which was also inhibited by blocking IL-17RB, but not IL-17RA. The PI3K-specific inhibitor LY294002 also completely attenuated IL-25-induced bFGF expression. Immunoreactivity for IL-25 and bFGF was elevated in the asthmatic bronchial mucosa and the expression of each correlated with the other. CONCLUSIONS AND CLINICAL RELEVANCE Our data support the hypothesis that IL-25 contributes to elevated bFGF in asthmatic airways by acting on the endothelial cell IL-17RB receptor through PI3K-signalling pathways. Targeting the pathways might benefit therapy of airways remodelling.
