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.

Deproteinized calf blood injection is composed of small protein-free molecules extracted from fresh calf blood. The pre-vious studies showed that it can improve metabolic balance by increasing glucose and oxygen uptake to enhance energy metabolism. In recent years, due to the expanding clinical applications of deproteinized calf blood injection, new observation results and ideas contin-ued to emerge. However, the reports of adverse reactions and excessive applications were also gradually increased. In order to provide reference for the promotion of reasonable clinical application, the paper reviewed the latest development in the studies on the clinical application of deproteinized calf blood injection.

ObjectiveTo observe the retinal function and nerve fiber layer (RNFL) thickness after laser in situ keratomileusis (LASIK). MethodsLASIK was performed in 15 cases (30 eyes) with myopia after strict preoperative examination. All examinations such as vision, correction vision, diopter, intraocular pressure, corneal thickness, ocular axis, topography scan and fundus of eye examination were performed before and 1 day, 1 week, 1 month,3 months and 6 months after operation, as well as electroretinography (ERG), visual evoked potential (VEP), optical coherece tomography at same time. ResultsThere was not significant difference in the intraocular pressure, ERG and VEP 1 day after LASIK. The thickness of RNFL decreased 1 week after LASIK (P<0.05) and recovered 1~6 months later. ConclusionLASIK does not disturb the retinal function and RNFL thickness irreversiblely.
