Plastic harmful ingredients reduce the level of neurofilament light chain protein.

Population exposure to plastics is increasing, and plasticizers are frequently detected in humans as important ingredients of plastic products. However, patterns of exposure to harmful ingredients of plastics and their effects on neurofilament light chain (NFL), a marker of active brain pathology, are currently inconclusive. Herein, we employed a range of statistical methods to thoroughly investigate the impact of 24 plastic hazardous ingredients and their varying exposure patterns on NFL concentrations in the blood of the general population in 533 participants.

Quantitative evaluation of warm acupuncture-moxibustion in improvement of cartilage damage in rabbits with early knee osteoarthritis based on MR T2 mapping.

Objectives: To observe the application value of MR T2 mapping for evaluating the effect of warm acupuncture-moxibustion on articular cartilage degeneration, and to observe the relationship between T2 value and expression of matrix metalloproteinases (MMP)-1 and MMP-13 of chondrocytes in rabbits with early knee osteoarthritis (KOA).

Methods: Thirty male New Zealand rabbits were randomly divided into blank control, KOA model and warm acupuncture-moxibustion groups, with 10 rabbits in each group. The early KOA model was established by right hind limb tubular plaster extension fixation method for 2 weeks.

[Warm acupuncture stimulation improves cartilage damage and motor function by regulating JAK2/STAT3 signaling pathway in rabbits with knee osteoarthritis].

Objective: To observe the effect of warm acupuncture on the expression of Janus protein tyrosine kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway and inflammatory factors of articular cartilage in rabbits with knee osteoarthritis (KOA), so as to explore its underlying mechanisms in improving KOA.

Methods: New Zea-land rabbits were randomly divided into blank, model, warm acupuncture and medication groups (12 rabbits in each group). The KOA model was prepared by using the right hind limb tubular plaster extension fixation method.

Warming moxibustion attenuates inflammation and cartilage degradation in experimental rabbit knee osteoarthriti.

Objective: To explore the molecular mechanism of warming moxibustion (WM) in knee osteoarthritis (KOA).

Methods: The knee joints of 40 New Zealand rabbits were placed in a plaster cast in an extended position to establish a KOA model. The animals were randomly divided into four groups: the control group, model group, WM group, and diclofenac (DF) group.

Effect of Warm Acupuncture Combined with Bone Marrow Mesenchymal Stem Cells Transplantation on Cartilage Tissue in Rabbit Knee Osteoarthritis.

The current study was designed to investigate the effect and underlying mechanism of warm acupuncture combined with bone marrow mesenchymal stem cells (BMSC) transplantation on cartilage tissue injury in rabbit knee osteoarthritis (KOA). In the study, 50 rabbits were randomly divided into 5 groups: blank group, KOA group, warm acupuncture group, BMSCs group, and warm acupuncture combined with BMSCs group. After warm acupuncture combined with BMSCs, the Modified Lequesne MG knee joint assessment scale was used to evaluate the degree of knee joint behavior, the Taiping Peng method generally observed the histomorphology changes of KOA rabbit cartilage, and hematoxylin-eosin staining, safranin O green staining, and toluidine blue staining were conducted to evaluate the extent of cartilage tissue pathology.
