Risk factors for the outcome and prognosis of multiple myeloma patients with pathological fractures undergoing percutaneous vertebroplasty.

This study focuses on the clinical features affecting the outcome and prognosis of multiple myeloma (MM) associated with spinal fractures. We retrospectively analyzed the clinical data of 194 MM patients with pathologic thoracic or lumbar spine fractures admitted to Dongying People's Hospital from April 2005 to February 2021. Patients were categorized into effective and ineffective groups based on post-treatment pain scores and mobility to analyze the influencing factors on the efficacy.

Ultrasonic bone curette-assisted unilateral approach for bilateral decompression with MIS-TLIF for severe lumbar spinal stenosis.

Purpose: We aimed to evaluate the clinical efficacy of bilateral decompression with minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) assisted by an ultrasonic bone curette (UBC) for treating severe degenerative lumbar spinal stenosis (DLSS) and traditional tool laminectomy decompression MIS-TLIF for treating severe DLSS.

Methods: The clinical data of 128 patients with single-segment severe DLSS who were admitted between January 2017 and December 2021 were retrospectively analyzed. Among them, 67 patients were treated with unilateral fenestration and bilateral decompression MIS-TLIF using an ultrasonic bone curette (UBC group), whereas 61 patients were treated with unilateral fenestration and bilateral decompression MIS-TLIF using traditional tools (traditional group, control).

Gelsemium elegans cyclic peptide induces human cervical carcinoma cells apoptosis through intrinsic and extrinsic pathways.

Four novel Gelsemium elegans cyclic peptides (GEPs) were isolated in an antihuman cervical carcinoma activity tracking method, and their amino acid sequences were identified. The GEP-1 cyclic-(Trp-Leu-His-Val)-peptide inhibited HeLa cell proliferation in a dose- and time-dependent manner. GEP-1 induced intracellular reactive oxygen species (ROS) overproduction and induced HeLa cells apoptosis in a caspase-dependent manner.

Structural characterization and anticancer potency of centipede oligopeptides in human chondrosarcoma cancer: inducing apoptosis.

Anticancer oligopeptides are rarely studied because they are often present in very low concentrations in a complex matrix. In the current study, twelve oligopeptides were isolated and the amino acid sequence identified from the centipede. MTT results indicated that Trp-Gly-His-Glu (CO-10) showed excellent anti-proliferative potency against chondrosarcoma cells .
