Comparison of the Outcomes of Endoscopic Posterolateral Interbody Fusion and Lateral Interbody Fusion in the Treatment of Lumbar Degenerative Disease: A Systematic Review and Network Meta-Analysis.

Objective: Although endoscopic technologies have been increasingly applied in lumbar fusion surgery in recent years, the advantages and disadvantages of endoscopic posterolateral fusion compared with lateral fusion remain unclear. Six different single-level lumbar interbody fusion procedures were compared to determine whether indirect decompression fusion could achieve levels of efficacy and safety comparable to those of minimally invasive direct decompression fusion in the treatment of lumbar degenerative disease (LDD).

Method: A literature search was conducted in the PubMed, Embase, and Cochrane Library databases, and studies on the treatment of LDD published from 2004 to March 2024 were retrieved.

Safety and efficacy of low-powered holmium laser enucleation of the prostate in comparison with plasma kinetic resection of prostate.

To compare the efficacy and safety of low-power holmium laser enucleation of the prostate (LP-HoLEP) with plasma kinetic resection of prostate (PKRP). Sixty-three patients treated with transurethral LP-HoLEP (observation group) and 68 patients treated with transurethral PKRP (control group) at Beijing Hospital of Traditional Chinese Medicine from November 2019 to November 2022 were retrospectively compared with regard to operation duration, intra-operative blood loss, prostate resection ratio, postoperative bladder irrigation time, postoperative indwelling urinary catheter time, postoperative urinary incontinence incidence, International Prostate Symptom Scale (IPSS), maximum urine flow rate (Qmax), and residual urine volume (RUV). In both groups, postoperative IPSS, Qmax, and RUV were significantly improved compared to preoperative values (P < 0.

Mixed pancreatic ductal adenocarcinoma and well-differentiated neuroendocrine tumor: A case report.

Background: Pancreatic mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) are rare malignancies affecting the pancreas. The World Health Organization defines MiNENs as neoplasms composed of morphologically recognizable neuroendocrine and non-neuroendocrine components, each constituting 30% or more of the tumor volume. Adenocarcinoma-neuroendocrine carcinoma is the most frequent MiNEN combination.

Molecular design of ternary copolymers with high photothermal performance in the near-infrared window for effective treatment of gliomas in vivo.

Photothermal therapy (PTT) is a promising approach for treating glioblastoma multiforme (GBM) with minimal invasiveness and favorable outcomes. Conjugated polymers as photothermal agents offer stability, biocompatibility, and adjustable absorption capacity. However, existing polymers face limitations in achieving high photothermal conversion efficiency and strong absorbance in the near-infrared (NIR) region, posing a risk of damaging healthy tissues surrounding GBM during precise PTT.

Oblique Lumbar Interbody Fusion Combined With Anterolateral Fixation and Cement Augmentation for the Treatment of Degenerative Lumbar Diseases in the Elderly Population: A Retrospective Study.

Objectives: Cage subsidence is a common complication of oblique lumbar interbody fusion (OLIF), particularly in elderly patients with osteoporosis or osteopenia. While bilateral pedicle screw fixation (BPS) is effective in reducing subsidence, it is associated with longer operative times, increased blood loss, and greater tissue trauma. In contrast, anterolateral fixation (AF) is less invasive but linked to higher subsidence rates.

Evaluating the reliability and validity of a Chinese version of the performance-oriented mobility assessment among patients with chronic stroke.

Background: The Performance-Oriented Mobility Assessment (POMA) is a reliable instrument for evaluating the mobility (balance and gait) of patients with chronic stroke to manage their risk of falling; however, it has not been validated among Chinese patients with stroke. This study aimed to evaluate the reliability and validity of the Chinese POMA in patients with stroke.

Methods: The POMA was applied to volunteer patients with stroke from the Shanghai MCC Hospital.

Chondrocyte autophagy mechanism and therapeutic prospects in osteoarthritis.

Osteoarthritis (OA) is the most common type of arthritis characterized by progressive cartilage degradation, with its pathogenesis closely related to chondrocyte autophagy. Chondrocytes are the only cells in articular cartilage, and the function of chondrocytes plays a vital role in maintaining articular cartilage homeostasis. Autophagy, an intracellular degradation system that regulates energy metabolism in cells, plays an incredibly important role in OA.

Cell surface receptor-mediated signaling in CNS regeneration.

Degenerative diseases and injuries of central nervous system (CNS) often cause nerve cell apoptosis and neural dysfunction. Protection of surviving cells or inducing the differentiation of stem cells into functional cells is considered to be an important way of neurorepair. In addition, transdifferentiation technology emerged recently is expected to provide new solutions for nerve regeneration.

Effects of 6-week olanzapine treatment on serum IL-2, IL-4, IL-8, IL-10, and TNF-α levels in drug-naive individuals with first-episode schizophrenia.

Background: Schizophrenia is a complex neuropsychiatric disorder. Growing evidence indicates that the activation of the inflammatory response system with interleukin (IL)-2, IL-4, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α) plays an important role in the pathogenesis of schizophrenia,. However, clinical data on cytokine levels in patients with schizophrenia treated with antipsychotics are inconsistent or inconclusive.

The influence of adult urine lead exposure on bone mineral densit: NHANES 2015-2018.

Introduction: Previous studies have indicated that exposure to heavy metals related to bone health is primarily limited to some common harmful metals, and the impact of lead has not been fully understood. This study aims to explore the relationship between urine lead exposure and bone density.

Methods: 1,310 adults were included from the NHANES database (2015-2018), and through generalized linear regression analysis and constrained cubic spline models, the association between lead levels and total bone density as well as lumbar spine bone density was explored.

Identification of Biomarkers and Mechanisms Associated with Apoptosis in Recurrent Pregnancy Loss.

In this study, we employed bioinformatics techniques to identify genes associated with apoptosis in recurrent pregnancy loss (RPL). We retrieved the RPL expression profile datasets GSE165004 and GSE73025 from the Gene Expression Omnibus (GEO) database. We also obtained data from the Kyoto Encyclopedia of Genes and Genomes (KEGG) Pathway of Apoptosis (hsa04210) to identify apoptosis-related genes.

CRISPR/Cas13d targeting suppresses repeat-associated non-AUG translation of C9orf72 hexanucleotide repeat RNA.

A hexanucleotide GGGGCC repeat expansion in the non-coding region of the C9orf72 gene is the most common genetic mutation identified in patients with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). The resulting repeat RNA and dipeptide repeat proteins from non-conventional repeat translation have been recognized as important markers associated with the diseases. CRISPR/Cas13d, a powerful RNA-targeting tool, has faced challenges in effectively targeting RNA with stable secondary structures.
