The main focus of this study is to investigate the clinical efficacy of external fixation treatment using removed locking plates in patients with failed debridement and antimicrobial therapy of infection after internal fixation of fractures. From January 2019 to January 2023, our medical institution treated 13 patients who had failed debridement and antimicrobial therapy for infection after internal fixation of fractures. All patients had their internal fixation devices removed, underwent thorough debridement, and then the removed locking plates were repurposed for external fixation treatment.

Methods: A total of 1,047 limb osteomyelitis patients aged 18 years or older who underwent debridement and intraoperative culture at our clinic centre from 1 January 2011 to 31 December 2020 were included. Patient characteristics, infection eradication, and complications were analyzed between culture-negative and culture-positive cohorts.

Physical activity (PA) is an effective intervention to combat obesity, but the effectiveness of different PA patterns on controlling obesity is unclear. Lipid accumulation product (LAP), derived from waist circumference and triglycerides, is a novel indicator for obesity evaluation.

Weakly supervised temporal action localization (TAL) aims to localize the action instances in untrimmed videos using only video-level action labels. Without snippet-level labels, this task should be hard to distinguish all snippets with accurate action/background categories. The main difficulties are the large variations brought by the unconstraint background snippets and multiple subactions in action snippets.

Background: The main aim of this article was to propose a new concept of minimally invasive surgery for treating limb fractures, named as second to minimally invasive plates osteosynthesis (STMIPO).
Methods: We have described the STMIPO technique in a step-wise and standardized manner based on our findings from a study involving six patients treated at our institution. All patients with fracture achieved satisfactory outcomes.

Insertion of polymethyl methacrylate (PMMA) bone cement can form an induced membrane(IM) and showed promising strategy for bone defect reconstruction, the underlying mechanism remains unclear. Our study sought to determine whether IM-derived cells(IMDCs) versus PSCs have similar characteristics in bone regeneration.

Methods: We included adult patients with limb osteomyelitis who received debridement and ALCS insertion into the bone defect as definitive management between 2013 and 2020 in our clinical centre. The follow-up time was at least two years.
Background: Vaccines are urgently required to control Staphylococcus aureus hospital and community infections and reduce the use of antibiotics. Here, we report the safety and immunogenicity of a recombinant five-antigen Staphylococcus aureus vaccine (rFSAV) in patients undergoing elective surgery for closed fractures.
Methods: A randomized, double-blind, placebo-controlled, multicenter phase 2 clinical trial was carried out in 10 clinical research centers in China.

Objective: The Python research environment for radiation therapy (PyRERT) is a set of business software for hospital physicists to conduct radiation therapy research.
Methods: Choose the open source Enthought Tool Suite(ETS) as the core external dependency library of PyRERT. PyRERT is divided into base layer, content layer and interaction layer, and each layer is composed of different functional modules.
In this study, we treated infected ankle bone defects with the induced membrane two-stage technique. The ankle was fused with a retrograde intramedullary nail in the second stage, and the aim of this study was to observe the clinical effect. We retrospectively enrolled patients with infected bone defects of the ankle admitted to our hospital between July 2016 and July 2018.

Nevertheless, the interaction characteristics between key microbial communities and environmental factors in response to Cd stress in specific crop environmental systems need to be explored. In this study, the soil (ferralsols)-microbe-crop (potato) system was taken as the object to explore the potato rhizosphere microbiome, using toxicology and molecular biology approaches, to explore the potato rhizosphere soil properties, microbial stress characteristics, and important microbial taxa under Cd stress.
