Analysis of risk factors of axial neck pain in posterior cervical single-door laminoplasty from the perspective of cervical sagittal plane.

Objective: We carried out this study to explore the possible relationship between the cervical sagittal parameters in radiological images and axial neck pain (ANP) for patients who had underwent posterior cervical single-door laminoplasty.

Method: 141 patients were enrolled in the study from January 2018 to January 2021, among which 38 were enrolled into the ANP group and 103 were enrolled into the non-ANP group. C2-7 Cobb angle, C2-7 sagittal vertex axis (SVA), thoracic inlet angle, neck tilt, and T1 slope were measured using computed Logistic regression was carried out to analyze the potential risk factor for the occurrence of ANP.

Purification and antioxidant and anti-Inflammatory activity of extracellular polysaccharopeptide from sanghuang mushroom, Sanghuangporus lonicericola.

Background: Sanghuang mushrooms are medicinal fungi widely used in eastern Asia. In this study, the antioxidant and anti-inflammatory activity of a novel extracellular polysaccharopeptide, sanghuang extracellular polysaccharopeptide (SePSP) was investigated. The SePSP was purified from the submerged fermentation broth of a sanghuang mycelium, Sanghuangporus lonicericola strain CBS17, which was isolated from a wild sanghuang fruiting body.

Performance of layered double hydroxides intercalated with acetate as biodenitrification carbon source: The effects of metal ions and particle size.

In situ synthesis of layered double hydroxides (LDHs) is an effective way to extract short chain fatty acids (SCFAs) from anaerobic fermentation liquid to be used as carbon source for biodenitrification, but the slow release performance need to be improved. Three layered double hydroxides with different metal cations (Mg-Al, Ni-Al, Ni-Fe) intercalated with acetate (Ac) were successfully prepared in the present study. The release rates decreased in the order of MgAl-LDH > NiAl-LDH > NiFe-LDH, meaning that NiFe-LDH-Ac showed the best slow release performance.
