The analgesic effect of continuous adductor canal block combined with popliteal plexus block for total knee arthroplasty: a randomized controlled trial.

This study aimed to confirm the hypothesis that continuous ACB (CACB) combined with a popliteal plexus block (PPB) can improve posterior knee pain, reduce nalbuphine consumption, and shorten the length of hospital stay. Patients who underwent TKA were allocated to the CACB + sham block (SHAM) or CACB + PPB groups. The primary outcome was the maximum pain score originating from the posterior knee within 4 h after TKA.

Application of urease-producing microbial community in seawater to dust suppression in desert.

In order to solve the dust problem caused by sandstorms, this paper aims to propose a new method of enriching urease-producing microbial communities in seawater in a non-sterile environment. Besides, the difference of dust suppression performance of enriched microorganisms under different pH conditions was also explored to adapt the dust. The Fourier-transform infrared spectrometry (FTIR) and Scanning electron microscopy (SEM) confirmed the formation of CaCO.
