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.

Objective To investigate the relationship between childhood obesity,asthma and lung function.Method Based on body weight and whether with asthma the 45 children were divided into normal control group,asthma group,obesity and asthma group,15 cases each.Each child was measured leptin levels and pulmonary function was measured with a spirometer.Each asthmatic children was surveyed by Asthma Control Test (C-ACT) questions.Results Asthmatic children have varying degrees harm of lung function.Obesity and asthma group compared with asthma group of children is more decreased in lung function.Children with asthma compared with normal control group of children is more higher in serum leptin concentration.Obesity and asthma children is highest in serum leptin concentrations.Asthmatic children C-ACT average score than obesity and asthma score,the difference was statistically significant (P ＜ 0.01).Conclusion Lung function and leptin abnormalities are exist in children with asthma.Also in the case of asthma,the abnormal levels of lung function and leptin in obese children compared with normal-weight children are more apparent,C-ACT score are more lower,and asthma is more severe.Weight control in obese children with asthma is favorable measures to control asthma attacks.

BACKGROUND: The integrity of the dura mater is very important for prognosis of patients with brain injury prognosis. Artificial dura mater is a commonly repair material, and to look for an ideal artificial dura mater is the exploration direction in the neurosurgery field. OBJECTIVE: To observe and analyze the clinical data of brain injury patients undergoing repair of colagen sponge as dura mater substitute material with ozone therapy, and to explore and evaluate its clinical value. METHODS: Folow-up results of therapeutic efficacy and complications in 60 cases of brain injury folowing repair with colagen sponge artificial dura mater and ozone treatment were retrospectively analyzed. RESULTS AND CONCLUSION:Two patients died of postoperative diffuse brain sweling, one died of brain injury with multiple organ failures, and two cases of extensive brain injury accompanied by cerebral herniation were in vegetative state. The rest 55 patients were enroled in the final analysis. After surgery, two patients appeared to have postoperative subcutaneous fluid and their conditions improved folowing puncture aspiration and pressure dressing with elastic bandage; another patient showed a smal amount of subdural effusion, but did not undergo special treatment, and dynamic head CT showed the effusion was gradualy reduced. Cranial CT examination showed no abnormalities associated with the artificial dura mater. At 3-6 months after surgery, the artificial dura mater was fused wel with the normal dura mater in 28 cases undergoing skul patching, and there was no adhesion and inflammatory reaction. Taken together, the colagen sponge artificial dura mater with ozone can give ful play to the decompression treatment of traumatic brain injury, which can maintain the brain function, shorter operative time, result in fewer complications, and have good compatibility, and moreover, the artificial dura mater can be fused wel with the normal dura to protect the brain cortex, thereby providing favorable conditions for the latter skul repair.

To study the anti-inflammatory activity of glycyrrhizin acid, ligustrazine and puerarin. In the study, the liquichip-based high-throughput synchronous detection technique for 23 inflammatory factors, uniform design, comprehensive weight method were adopted to study the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin in inhibiting the expression of lipopolysaccharide (LPS)-induced RAW264. 7 cells and multiple inflammatory cytokines. In the study, the uniform design table U₉ (9³) was adopted to design doses of glycyrrhizin acid, ligustrazine and puerarin. The liquichip technique was used to detect the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin on the 23 cytokines expressed in LPS-induced mouse macrophage RAW264. 7 inflammation model. The traditional Chinese medicine component optimization software and the improved least angle regression algorithm were used to analyze the dose-effect relationship among the three components and the cytokine inhibition rate and produce the regression equation. The comprehensive weight method was applied to get the optimal dose ratio of glycyrrhizic acid, ligustrazine and puerarin with highest efficacy of 25:2:13 and verify the optimal dose ratio. The verification results were consistent with the prediction trend, indicating the accuracy of the mathematical model for predicting the experiment. The experimental results showed the multi-target and multi-level efficacies of glycyrrhizic acid, ligustrazine and puerarin and the high anti-inflammatory activity of their combined administration, which provides powerful basis for subsequent drug development.
