Objective To investigated the efficacy of celecoxib for postoperative analgesia after endoscopic nasal surgery. Methods One hundred and twenty ASA Ⅰ or Ⅱ patients of both sexes aged 18-64 yr were randomly assigned to one of three groups ( n = 40 each): control group ( group C); celecoxib 200 group ( group CEL1 ) and celecoxib 400 group ( group CEL2 ). The patients took celecoxib 200 and 400 mg by mouth at 1 h before induction of anesthesia in group CEL1 and CEL2 respectively. Anesthesia was induced with midazolam,propofol, remifentanil and rocuronium and maintained with iv propofol and remifentanil infusion. VAS was used to assess postoperative pain (0 = no pain, 10 = worst pain). In PACU when VAS score ≥3, the patients were given fentany125 μg iv every 5-10 min until the VAS score < 3. After being discharged from PACU, the patients received celecoxib 200 mg every 12 h for 5 days in the 2 celecoxib groups. Oxycodone 5 mg was used as rescue analgesic when VAS score ≥ 4 until the VAS score < 4. The number of patients who needed fentanyl for analgesia in PACU, the number of patients who needed oxycodone within 6 h, 6-24 h and day 2-5 after operation and side effects after operation were recorded. Analgesic efficacy was assessed at day 5 after operation and the satisfactory rate of patients calculated. Blood samples were obtained at 0, 6 and 48 h after operation for determination of PGE2,6-k-PGF1α and TXB2 concentrations. TXB2/6-k-PGF1α was calculated. Results The number of patients who needed fentanyl in PACU and the number of patients who needed oxycodone within 6 h and 6-24 h after operation were less, the satisfactory rate was significantly higher, and PGE2 concentrations in blood were significantly lower at 48 h after operation in the 2 celecoxib groups than in group C ( P < 0.05 or 0.01 ). There was no significant difference in each index between the 2 celecoxib groups ( P > 0.05 ). There was no significant difference in TXB2/6-k-PGF1α at each time point among the three groups. Nausea and vomiting occurred in one patient after operation in group C, but side effects were not observed in the 2 celecoxib groups. Conclusion Celecoxib given before and after operation can effectively relieve postoperative pain after endoscopic nasal operation by reducing PGE2 concentrations in blood.

Glycyrrhizin acid and licorice flavonoids are the component of Glycyrrhiza uralensis Fisch root that has been used for various medicinal purposes in traditional oriental medicine for thousands of years. Macrophages as a principal component of immune system play an important role in the initiation, modulation and final activation of immune response against pathogens. In the present study, glycyrrhizin acid and licorice flavonoids was investigated the anti-inflammatory effect on lipopolysaccharide (LPS)-induced macrophage cell line of RAW264.7. Well-grown RAW264.7 cells were collected and randomly divided into the blank control group, the LPS(1 mg x L(-1)) group, the dexamethasone (5 mg x L(-1)) with LPS group, the glycyrrhizin acid (400, 80, 16 mg x L(-1)) with LPS group and the licorice flavonoids (200, 40, 8 mg x L(-1)) with LPS group. RAW264.7 cells were cultured in 24-well plates, pre-incubated for 4 h with different concentrations of dexamethasone, glycyrrhizin acid, or licorice flavonoids. Then cells were stimulated for 20 h with LPS. The supernatant of culture medium was collected from each well and determinated the concentrations of cytokines by means of BioPlex mouse cytokines assay. Compared with the control group, the LPS group could significantly induced relatively high levels of granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor( GM-CSF), macrophage inflammatory protein-1 alpha (MIP-1α), macrophage inflammatory protein-1 beta (MIP-1β), regulated upon activation normal T cell expressed and secreted factor (RANTES), tumor necrosis factor alpha ( TNF-α), monocyte chemotactic protein 1 (MCP-1), chemokine (C-X-C motif) ligand 1 (KC), eotaxin, interleukin(IL)-1α, IL-1β, IL-3, IL-4, IL-5, IL-6, IL-10, IL-12 (p40), IL-12 (p70), IL-13, and IL-17 secretion (P < 0.05). The glycyrrhizin acid significantly inhibited IL-1β, IL-3, IL-5, IL-6, IL-10, IL-12 (p40), IL-12 (p70), IL-13, Eotaxin and TNF-α secreted by LPS-stimulated RAW264.7 cells (P < 0.05). The expression levels of IL-6 and Eotaxin were observably decreased in the licorice flavonoids with LPS group (P < 0.05). The data presented here suggested that the glycyrrhizin acid and licorice flavonoids modulate various cytokines secreted by macrophages and were important anti-inflammatory constituent of Licorice.
