Background: To analyze the safety and efficacy of microsurgical subinguinal varicocelectomy(MSV) performed with and without preservation of all testicular arteries and lymphatic system.

Background: Functional mitral regurgitation (MR) is a common form of mitral valve dysfunction that often persists even after surgical intervention, requiring reoperation in some cases. To advance our understanding of the pathogenesis of functional MR, it is crucial to characterize the cellular composition of the mitral valve leaflet and identify molecular changes in each cell subtype within the mitral valves of MR patients. Therefore, we aimed to comprehensively examine the cellular and molecular components of mitral valves in patients with MR.

The preoperative MRI assessment of rectal cancer is crucial for patient management, but the imaging quality is currently limited by a number of factors. DLR could be applied to the preoperative MRI assessment of primary rectal cancer, but research about its specific reliability is limited.

Objective: To investigate the risk factors of death within 7 days in patients with acute myocardial infarction (AMI) complicated by ventricular septal rupture (VSR) based on echocardiography indicators, and to construct a nomogram model of ultrasound indicator risk to predict the risk of death in patients with post-infarction ventricular septal rupture (PIVSR).
Methods: The echocardiographic data of 40 patients with PIVSR admitted to the department of cardiology, Xiangya Third Hospital, Central South University from January 2014 to June 2024 were retrospectively analyzed. The patients were divided into death group and survival group based on their 7-day survival status.
Acute aortic dissection is considered a contraindication to the use of intravenous thrombolysis in patients presenting with acute ischaemic stroke, but less has been described about previously repaired dissections. We present a case of a woman in her 50s presenting with acute left hemiparesis with a known history of aortic dissection within the thrombolysis window. After multidisciplinary discussion with cardiothoracic surgery and discussion with the patient, she was treated with intravenous thrombolysis without complication.

Construct a mouse model with specific knockout of the Bmal1 gene in the thyroid (T-Bmal1) (knockout group, =10), and use Bmal1 mice without thyroid peroxidase-cyclization recombination enzyme (T-Bmal1) as the control group (non-knockout group, =10). The mice were fed until 6 weeks (body weight 20-23 g), and then use the random number table method to evenly divide each group of mice into two subgroups.

Methods: To identify circ_0007439, microRNA (miR)-556-5p, and PTEN mRNA in NPC tissues and cells, RT-qPCR was employed.
Objective: This study aimed to analyze the correlation of adiponectin (APN) and leptin (LEP), reproductive endocrine hormones with insulin resistance (IR) in polycystic ovary syndrome (PCOS) patients with normal body mass index (BMI).
Methods: Totally 160 PCOS patients were categorized into the Normal BMI (BMI: 18.5-25 kg/m, = 62) and High BMI (BMI > 25 kg/m, = 98) groups.

With improvements in cancer-associated mortality and advancements in treatment of active malignancy, it is more common to encounter patients with ischemic stroke and active malignancy. Evidence suggests that cancer-associated ischemic stroke is a unique subtype of stroke; however, there is limited guidance when considering diagnostic workup, secondary prevention, rehabilitation, and future directions within this population.

5-Fluorouracil (5-FU) resistance poses a significant challenge in the treatment of rectal cancer, driving the need for novel therapeutic strategies. In this study, we established 5-FU-resistant rectal cancer cell lines (SW837-r, SNU-C1-r) and identified homoharringtonine (HHT) as a potent and selective anticancer agent through high-throughput drug screening of 291 compounds. HHT displayed the highest selective drug sensitivity score (sDSS), showing strong activity against resistant cells while sparing normal rectal epithelial cells.

However, conventional passive metasurfaces are severely limited by poor reconfigurability, which makes it difficult to achieve wavefront manipulations in real time. Here, we propose a holographic communication strategy that on-demand target information is firstly acquired and encoded via a depth camera integrated with modified YOLOv5s target detection algorithm, then transmitted by software defined radio modules with long term evolution at 5 GHz, and finally reproduced in the form of holographic images by spin-decoupled programmable coding metasurfaces at 12 GHz after decoding through modified Gerchberg-Saxton algorithm.

We hypothesized that neuroimaging measures would be associated with treatment-related gains, examining performance of regional injury measures versus global brain health measures in parallel with clinical measures.
Methods: Baseline magnetic resonance imaging (MRI) scans in the VNS-REHAB trial were used to derive regional injury measures (extent of injury to corticospinal tract, the primary regional measure; plus extent of injury to precentral gyrus and postcentral gyrus; lesion volume; and lesion topography) and global brain health measures (degree of white matter hyperintensities, the primary global brain measure; plus volumes of cerebrospinal fluid, cortical gray matter, white matter, each thalamus, and total brain).

Herein, this study reports a double-SERS satellite immunoassay, made of an Au-Ag dealloyed intra-nanogap nanoflower (Au-Ag DINF) with strong SERS signals and Au magnetic nanoparticles (AuMNPs) with magnetic capture and SERS amplification, for sensing multiple PSA (free PSA (fPSA), complexed PSA (cPSA) and [-2]proPSA (p2PSA)) toward potential PCa screening. Unlike the previous studies focus on the tPSA and fPSA/tPSA ratio (f/t PSA%), this work introduces a multiple PSA-mediated Prostate Health Index (PHI) assay with significantly increased the predictive accuracy and specificity of PCa, especially the patients with a tPSA level in the "diagnostic gray zone".

In this study, we screened various essential and non-essential amino acids and found that methionine enhances mRNA methylation and reduced the activation of Type I interferon pathway in bladder cancer. Through RNA sequencing, point mutations, MB49 mouse tumor models, and single-cell RNA sequencing, we demonstrated that high methionine levels elevate the expression of mA reader YTHDF1, promoting the degradation of RIG-I, thereby inhibiting the RIG-I/MAVS-mediated IFN-I pathway and reducing the efficacy of tumor immunotherapy.
