4% [-10.1, -6.5] vs. -9.9% [-12.8, -8.1], p<.01), both on univariate and baseline LV volumes-adjusted analyses. Baseline LA strain for reservoir and conduit phases were not associated with significant LVR at follow-up. Intra- and interobserver analysis showed good reproducibility of LA strain.

Baseline LASct may help identifying patients without HF after STEMI who are at higher risk of further early LVR and subsequent HF and who may benefit from more intensive management.

The success of transcatheter aortic valve replacement (TAVR) in native aortic regurgitation (AR) is limited by the absence of calcified anchoring structures. We sought to evaluate transfemoral TAVR in patients with native AR using a novel aortic root imaging classification.

From March to November 2021, 81 patients with severe AR were prospectively enrolled in 2 cardiac centers in China. All were evaluated using multidetector computed tomography (MDCT) and classified into 4 anatomic types in reference to transcatheter heart valve (THV) anchoring Type 1 anchoring at the left ventricular outflow tract (LVOT), annulus, and ascending aorta (AA); Type 2 anchoring at the annulus and AA; Type 3 anchoring at the annulus and LVOT; and Type 4 anchoring at only 1 level or none at all. Based on the dual-anchoring strategy, patients with Types 1-3 were considered TAVR candidates. Procedural and 30-day outcomes were assessed according to Valve Academic Research Consortium-3 definitions.

TAVR was performed in 32 (39.5%) patients (71.9±8.0 years of age, 71.9% were male) using 2 self-expanding THVs. Types 1, 2, and 3 comprised 13 (40.6%), 11 (34.4%), and 8 (25.0%) cases, respectively. The procedural and device success rates were 100% and 93.8%, respectively, with 2 THV migration. Eight patients (25.0%) required a permanent pacemaker, and 2 (6.3%) developed moderate paravalvular leaks. No deaths or other major complications occurred during the study.

The novel anatomic classification and dual-anchoring strategy were associated with a high procedural success rate with favorable short-term safety and clinical outcomes.

However, conventional bacteria-based immunotherapy often suffers from dose-dependent safety issues and poor treatment efficacy. Harnessing surface modification of bacteria to carry additional immune modulators has emerged as a promising strategy to reduce bacterial dose and synergistically enhance the activation of immune responses. In this paper, bacteria-mediated immunomodulation and the underlying mechanisms are introduced, followed by a summarization on the concept of using surface-modification approaches including physical encapsulation, chemical conjugation, and metabolic labelling to combine diverse immune functions. The applications of modified bacteria as therapeutics for immunotherapy toward cancer and inflammatory bowel disease have been expounded further. Both challenges and future perspectives regarding the utilization of surface-modified bacteria for immunomodulation are also proposed. This work offers unique insights into developing safe yet potent bacteria-based therapeutics for advanced immunotherapy.Compared to the more common epiphrenic diverticula, those located at the central section of the esophagus are quite rare. Minimally invasive approaches for mid-esophageal diverticula have lacked standardization. Certain mid-esophageal diverticula, like epiphrenic diverticula, have been attributed to esophageal motility disorders. Thus, we believe that surgery for esophageal diverticula requires preoperative evaluation of esophageal function, with additional surgery being performed in case of abnormalities. The laparoscopic trans-hiatal approach has been a common technique for managing epiphrenic diverticula but can also be used for mid-esophageal diverticula located far from the esophagogastric junction provided that the port location is carefully considered. Laparoscopic surgery is also preferable given that it is a minimally invasive procedure and allows for diverticulum resection and Heller myotomy and Dor surgery to prevent reflux in the same field of view. Hence, laparoscopic surgery may be a beneficial alternative to the traditional thoracic or thoracoabdominal techniques.

To investigate relationships between hypersensitive C-reactive protein (hs-CRP), tumor necrosis factor -α (TNF-α), interleukin-17A (IL-17A), and interferon -γ (IFN-γ), with left ventricular geometry (LVG) and function in patients with primary hypertension (PHT).

A total of 396 PHT patients were assigned into four groups Normal Geometry (NG), Concentric Remodeling (CR), Eccentric Hypertrophy (EH), and Concentric Hypertrophy (CH). The correlation between hs-CRP, TNF-α, IL-17A, IFN-γ, and clinical, biochemical parameters were analyzed by Pearson correlation analysis and Logistic regression. Receiver Operating Characteristic (ROC) curve was used to analyze the clinical values of hs-CRP, TNF-α, IL-17A, and IFN-γ for abnormal LVG prediction.

NG, CR, EH, and CH group all presented increasingly higher levels of Hs-CRP, TNF-α, IL-17A, and IFN-γ, and the increase was the most prominent in the CH group. Pearson correlation analysis showed that hs-CRP, IL-17A, and IFN-γ were all positively correlated with LASct. Hson, suggesting that inflammatory cytokines may be involved in the process of PHT-induced abnormal left ventricular structure and function. In addition, hs-CRP can be used as a health screening index for patients at high risk of abnormal LVG.

The main chemical components of Angelica dahurica (Hoffm.) Benth. & Hook.f. ex Franch. & Sav. are coumarins and volatile oils, and coumarins are regarded as the representative constituents with various pharmacological effects.

Based on matrix-assisted laser desorption/ionization time of flight mass spectrometry imaging (MALDI-TOF-MSI), a method for spatial distribution analysis of coumarins in primary root and lateral root of A. dahurica was established. Also, spatial visualization of coumarins in the roots of A. dahurica was realized.

α-Cyano-4-hydroxycinnamic acid (CHCA), 2,5-dihydroxybenzoic acid, and 9-aminoacridine were used as matrices. MALDI-TOF-MSI was employed to analyze the standards of imperatorin, oxypeucedanin, and osthole. Based on the higher sensitivity and repeatability of MALDI-TOF-MSI, the CHCA matrix was selected. The matrix was used for MALDI-TOF-MSI in positive mode to analyze the distribution of coumarins in primary root and lateral root of A. dahurica.

In total, 37 coumarins were detected in primary root and 36 coumarins were detected in lateral root by MALDI-TOF-MSI. The results showed that the coumarin content in primary root was higher than that in lateral root. Coumarins in primary root of A. dahurica were concentrated in the periderm, cortex, and phloem, whereas coumarins in lateral roots were concentrated in the phloem.

The coumarins in primary root and lateral root of A. dahurica were directly analyzed without extraction and isolation, and the spatial distribution of coumarins was comprehensively visualized for the first time by MALDI-TOF-MSI, which provided a basis for distinguishing primary root and lateral root.

To construct a prediction model based on functional mitral regurgitation (FMR) in patients with paroxysmal atrial fibrillation (PAF) to predict atrial fibrillation recurrence after the post-circular pulmonary vein radiofrequency ablation (CPVA).

We retrospectively analyzed 289 patients with PAF who underwent CPVA for the first time. The patients were randomly divided into modeling group and verification group at the ratio of 7525. In the modeling group, the multivariate logistic regression was used to analyze and construct a prediction model for post-CPVA recurrence in PAF patients, which was then validated in the verification group.

(1) After 3-6 months of follow-up, the patients were divided into sinus rhythm group (252 cases) and recurrence group (24 cases); (2) In the modeling group, the age, left atrial diameter (LAD), and the degree of MR (mild, moderate, severe) were higher in recurrence group than that of the sinus rhythm group, and the left atrial appendage emptying velocity (LAAV) was lower in recurrence group (all p<.05). (3) A model for predicting the recurrence of PAF after radiofrequency ablation was constructed in the modeling group. Navitoclax chemical structure The equation was Logit(P)=-3.253 + .092 × age + 1.263 × mild MR + 2.325 × moderate MR + 5.111 × severe MR -.113 × LAAV. The area under the curve (AUC) of the model was .889 in modeling group and .866 in verification group, and the difference was not statistically significant (p>.05).

The prediction model of atrial fibrillation (AF) recurrence after CPVA in PAF patients has good predictive efficacy, specificity, and accuracy.

The formal pathogenesis of salivary carcinosarcoma (SCS) remained unclear, both with respect to the hypothetical development from either preexisting pleomorphic adenoma (PA) or de novo and the clonal relationship between highly heterogeneous carcinomatous and sarcomatous components.

We performed clinicopathological and molecular (targeted RNA sequencing) analyses on a large series of 16 cases and combined this with a comprehensive literature search (111 cases). Extensive sampling (average 11.6 blocks), combined with immunohistochemistry and molecular studies (PA-specific translocations including PLAG1 or HMGA2 proven in 6/16 cases), enabled the morphogenetic identification of PA in 15/16 cases (93.8%), by far surpassing a reported rate of 49.6%. Furthermore, we demonstrated a multistep (intraductal/intracapsular/extracapsular) adenoma-carcinoma-sarcoma-progression, based on two alternative histogenetic pathways (intraductal, 56.3%, versus myoepithelial pathway, 37.5%). Thereby, early intracapsular stages ggressive variant of carcinoma ex PA with secondary sarcomatous overgrowth. In analogy to changes of terminology in other organs, the term "sarcomatoid carcinoma ex PA with/without heterologous elements" might be more appropriate.

Little is known about whether resting left ventricular global longitudinal strain (GLS) impairment is associated with myocardial perfusion abnormalities evaluated using

N-ammonia positron emission tomography (

N-NH

-PET)-myocardial perfusion imaging (MPI). This study aimed to investigate the correlation between resting GLS and myocardial perfusion parameters in patients with a normal left ventricular ejection fraction (LVEF). We evaluated whether resting GLS can predict myocardial perfusion abnormalities in these patients.

We selected 157 patients with suspected stable angina pectoris who underwent both ATP-stress NH

-PET-MPI and 2-dimentional speckle tracing echocardiography. All subjects had a preserved LVEF and no known history of myocardial infarction. Patients were stratified into Group N (normal perfusion; summed stress score [SSS], 0-3; n=101), Group M (mildly to moderately abnormal perfusion; SSS, 4-11; n=41), or Group S (severely abnormal perfusion; SSS, 12+; n=15). GLS was more impaired as myocardial perfusion abnormality severity increased (-17.
