Objective: To investigate the effect of Polyetheretherketone (PEEK) rod semi-rigid pedicle screw fixation system in lumbar spine non-fusion surgery.
Methods: A total of 74 patients with tow-level lumbar degenerative diseases who underwent surgery from March 2017 to December 2019 were divided into PEEK rod group and titanium rod group. In the PEEK rod group, there were 34 patients, including 13 males and 21 females, aged from 51 to 79 years old with an average of (62.
Objective: To observe the early clinical effect of perfusion bone cement screw for lumbar degenerative diseases with osteoporosis.
Methods: The clinical data of 28 patients with lumbar degenerative diseases combined with moderate to severe osteoporosis treated by posterior lateral graft fusion with perfusion of bone cement screws from June 2015 to June 2017 were retrospectively analyzed. There were 9 males and 19 females, aged from 55 to 86 years old with an average of 76 years.
Although the Mobi-C artificial disc and the ROI-C cervical cage have been widely used in the treatment of cervical degenerative disc diseases (CDDD), few reports addressed the features of combined application of both devices. This study is aimed at comparing the clinical and radiological outcomes of treating contiguous two-level CDDD using Mobi-C and ROI-C combined in a hybrid surgery (HS) with anterior cervical discectomy and fusion (ACDF) using ROI-C. We reviewed ninety-one patients who underwent HS (n = 48) or ACDF (n = 43) surgery for symptomatic contiguous two-level CDDD.

- The study examines the effectiveness of self-locking stand-alone cages for cervical fusion and identifies different fusion states at the index level among 42 patients over a 5-year follow-up period.
- The overall fusion rate was high at 97.4%, with type IV showing the highest fusion proportion, and all types demonstrated significant improvement in clinical outcomes.
- The research highlights the dynamic nature of the fusion process and suggests that factors like cage location and cervical spine alignment may influence the fusion state, but all types resulted in satisfactory clinical results.
Article Synopsis
- A novel method using TurborFlow online solid phase extraction (SPE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed for screening and confirming 88 veterinary drugs in milk from various families, achieving results in under 39 minutes.
- The method includes sample dilution and ultrasonic extraction, followed by automated clean-up and detection using selected reaction monitoring mode (SRM), and has shown high reliability with R(2) values above 0.9930.
- Validation results show limits of detection as low as 0.2-2.0 μg/kg, and overall recovery rates for spiked compounds range from 63.1% to 117.4%, demonstrating its effectiveness and potential

A confirmatory and quantitative method based on liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) has been developed for simultaneous determination of 13 aminoglycoside antibiotics in various samples. The aminoglycoside analytes were released and extracted from different matrices with 5% trichloroacetic acid. The influence of pH values on the solid-phase exaction (SPE) procedure has been studied.
