Purpose: To investigate the effect of ultrasonic curettage combined with sodium hyaluronate gel in the treatment of chronic periodontitis (CP) and the effect on inflammatory factor hypersensitive C-reactive protein (hs-CRP), monocyte chemotactic protein 1 (MCP-1) and matrix metalloproteinase 13 (MMP-13) in gingival crevicular fluid.

Methods: A total of 102 patients with CP from October 2021 to October 2022 were selected, divided into experimental group (n=51) and control group (n=51) by random number table method. The control group received ultrasonic subgingival curetage, and the experimental group received sodium hyaluronate gel adjuvant therapy on the basis of the control group.

A drug-loaded diaphragm is an easy-to-use and effective drug delivery system that is often used to treat mouth ulcers. In this study, an ultrafine fiber film loaded with capsaicin was successfully prepared using the electrospinning technology. poly-L-lactic acid and gelatin were selected as the matrix materials to form the composite fiber, and trifluoroethanol was used as a co-solvent for poly-L-lactic acid, gelatin and capsaicin to prepare the spinning solution, which was simple to fabricate.

Purpose: The role of developmental endothelial locus-1 (DEL-1) in Porphyromonas gingivalis (P. gingivalis)-induced periodontitis and the related molecular mechanisms are unclear. This study aimed to investigate the effect of DEL-1 on SH3 Domain Binding Protein 2 (SH3BP2) expression, and to explore the regulatory role of DEL-1 in periodontal inflammation.

Tetramethylpyrazine (TMP) has anti-inflammatory effects and is used to treat cerebral ischemic injury, but the mechanism of TMP on neural protection is not clear. Trigeminal neuralgia (TN) is a facial pain syndrome that is characterized by paroxysmal, shock-like pain attacks located in the somatosensory distribution of the trigeminal nerve. P2X3 receptor plays a crucial role in facilitating pain transmission.

Transient receptor potential vanilloid1 (TRPV1) and glutamate receptors (GluRs) are located in small diameter primary afferent neurons (nociceptors), and it was speculated that glutamate released in the peripheral tissue in response to activation of TRPV1 might activate nociceptors retrogradely. But, it was not clear which types of GluRs are functioning in the nociceptive sensory transmission. In the present study, we examined the c-Fos expression in spinal cord dorsal horn following injection of drugs associated with glutamate receptors with/without capsaicin into the hindpaw.

Glutamate (Glu) is the major excitatory neurotransmitter in the central nervous system. The role of peripheral Glu and Glu receptors (GluRs) in nociceptive transmission is, however, still unclear. In the present study, we examined Glu levels released in the subcutaneous perfusate of the rat hind instep using a microdialysis catheter and the thermal withdrawal latency using the Plantar Test following injection of drugs associated with GluRs with/without capsaicin into the hindpaw.
