Preoperative 3D printing planning technology combined with orthopedic surgical robot-assisted minimally invasive screw fixation for the treatment of pelvic fractures: a retrospective study.

Objective: To explore the advantages and effectiveness of preoperative 3D printing planning technology combined with orthopedic surgical robot-assisted screw placement in the minimally invasive treatment of pelvic fractures compared to orthopedic surgical robot-assisted screw placement alone.

Methods: A retrospective analysis of the clinical data of 29 patients with unstable pelvic fractures treated with orthopedic surgical robot-assisted percutaneous screw fixation from July 2021 to August 2023 was conducted. Among them, 13 patients who underwent preoperative 3D printing technology for screw planning were assigned to the experimental group, and the remaining 16 patients were assigned to the control group.

Genistein promotes cartilage repair and inhibits synovial inflammatory response after anterior cruciate ligament transection in rats by regulating the Wnt/β-catenin axis.

To confirm the protective mechanism of genistein on osteoarthritis (OA). Firstly, we constructed an anterior cruciate ligament transection (ACLT) rat model and administered two doses of genistein via gavage. The effects of the drug on cartilage damage repair and synovitis in OA rats were evaluated through pain-related behavioral assessments, pathological staining, detection of inflammatory factors, and western blot analysis.

CircSmox knockdown alleviates PC12 cell apoptosis and inflammation in spinal cord injury by miR-340-5p/Smurf1 axis.

Background: Spinal cord injury (SCI) is a traumatic central nervous system disorder that leads to irreversible neurological dysfunction. Emerging evidence has shown that differentially expressed circular RNAs (circRNAs) after SCI is closely associated with the pathophysiological process. Herein, the potential function of circRNA spermine oxidase (circSmox) in functional recovery after SCI was investigated.

Reduction of NgR in perforant path protects neuronal morphology and function in APP/PS1 transgenic mice.

Neuronal loss is the central abnormality occurring in brains suffering from Alzheimer's disease (AD). The notion that AD causes the death of neurons point towards protection of neuronal morphology and function as important therapeutic strategies. The perforant path projections from the entorhinal cortex to the dentate gyrus is the most vulnerable circuit with respect to AD.

[Short-term effectiveness of orthopedic robot-assisted femoral neck system fixation for fresh femoral neck fractures].

Objective: To investigate the short-term effectiveness and advantages of the orthopedic robot-assisted femoral neck system (FNS) fixation in the treatment of fresh femoral neck fractures compared with the traditional manual operation.

Methods: A clinical data of 74 patients with fresh femoral neck fractures, who had undergone internal fixation with FNS between April 2020 and September 2021, was retrospectively analyzed. Among them, there were 31 cases of TiRobot-assisted operation (trial group) and 43 cases of traditional manual operation (control group).

EMX1 functions as a tumor inhibitor in spinal cord glioma through transcriptional suppression of WASF2 and inactivation of the Wnt/β-catenin axis.

Background: Gliomas are the most frequent and aggressive cancers in the central nervous system, and spinal cord glioma (SCG) is a rare class of the gliomas. Empty spiracles homobox genes (EMXs) have shown potential tumor suppressing roles in glioma, but the biological function of EMX1 in SCG is unclear.

Methods: The EMX1 expression in clinical tissues of patients with SCG was examined.

A potential diagnostic marker for osteosarcoma: hsa_circ_0005721.

Purpose: To detect the expression level of hsa_circ_0005721 in osteosarcoma specimen and plasma of osteosarcoma patients, and to analyze the clinical significance of hsa_circ_0005721 as a diagnostic marker for osteosarcoma.

Methods: Expression levels of hsa_circ_0005721 in osteosarcoma specimen and osteosarcoma cell lines were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The relationship between hsa_circ_0005721 expression difference and overall survival in osteosarcoma was analyzed by Kaplan-Meier method.
