Objective To study effects of oxycodone post-operative early analgesia on stress re-sponse with in diabetics undergoing uvulopalatopharyngoplasty (UPPP).Methods Eighty patients undergoing UPPP,53 males,27 females,aged 28-65 years,ASA Ⅰ or Ⅱ were randomly divided in-to two groups(n =40).1 5 minutes before the end of the operation,group O was intravenously given oxycodone 0.07 mg/kg;Group F fentanyl 0.7 μg/kg.The patients of the two groups were sampled venous blood 3 ml in the morning of operation (T1 ),postoperative 1 hour (T2 ),postoperative 3 hours (T3 )for determination of serum cortisol (Cor),serum insulin(Ins),serum C-peptide(C-P)u-sing electrochemical luminescence method.Results Cor at T2 ,T3 was lower than that at T1 , C-P was higher than that at T1 (P <0.05)in group O,respectively;Cor at T2 ,T3 was higher than that at T1 , respectively,C-P was lower than that at T1 (P <0.05);Cor in group F was higher than that in group O,C-P in group F was lower than that in group O(P <0.05).Ins at T2 ,T3 was lower than that at T1 and was lower than that in group O(P <0.05).Conclusion Oxycodone 0.07 mg/kg early analgesia for UPPP significantly inhibits the occurrence of stress response.

BACKGROUND:The treatment difficulties of thoracolumbar angular kyphosis surgery are:low correction rate, hard to rebuild sagittal plane, easily induce neurological complications, postoperative loss of balance, high incidence of pseudarthrosis and postoperative loss of correction degree.
OBJECTIVE:To explore the safety and efficacy of modified posterior vertebral column resection osteotomy and bilateral pedicle screw combined with echelon tight closure spinal cord technique and implant fixation for severe spinal angular kyphosis.
METHODS:A total of 87 severe spinal angular kyphosis patients, 36 males and 51 females, who were treated in the Department of Orthopedics, the 306 Hospital of Chinese PLA from January 2006 to December 2013, were enrol ed in this study. They underwent posterior vertebral column resection, bilateral pedicle screw combined with echelon tight closure spinal cord, and implant fixation. Kyphosis, spinal sagittal imbalance, offset rate towards trunk side, operation time and intraoperative blood loss were observed before and after treatment.
RESULTS AND CONCLUSION:The preoperative average kyphosis was 90.1° (31°-138°). The postoperative average kyphosis was 27.9° (15°-57°). The improvement rate was 76%. The improvement rate of trunk sagittal offset was 76%. Intraoperative blood loss was 800-3 000 mL, and average blood loss was 2 300 mL. The operation time was 5-7 hours, averagely 5.9 hours. Before treatment, two patients affected neurologic symptoms in double lower extremity, and their Frankel classification was grade C and became grade E after treatment. Al patients were fol owed up for 9-57 months. Bony fusion was achieved in al patients. No complications of spinal cord injury appeared, and no orthopedic angle missing occurred. These results indicate that during posterior vertebral column resection for treating severe angular stiffness of the thoracic kyphosis, blood vessels could be maintained greatly. Blood vessel injury-induced ischemic changes in spinal cord and ischemic reperfusion injury could be avoided. To reduce hemorrhage and to keep effective blood volume in patients with low body mass are effective for early recovery after treatment. Bilateral pedicle screw combined with echelon tight closure spinal cord technique greatly protected spinal cord cells against injury. We should pay attention to the protection and loose of nerve root to avoid postoperative nerve root irritation. Sufficient bone fusion ensures kyphosis correction, avoids spine lateral offset, and plays a key role in spinal function and postoperative orthopedic effect.

Objective:
To evaluate the relationship between bolus volume and hyoid displacement in dysphagia patients with nasopharyngeal carcinoma after radiation therapy.
Methods:
Twenty-three nasopharyngeal carcinoma patients with dysphagia were recruited and their swallowing of 3, 5, 10 and 20ml of liquid food was studied fluoroscopically. The vertical and horizontal displacement of the hyoid as well as its time in motion were measured, and the relationship between the bolus volume, hyoid displacement and time in motion time was evaluated.
Results:
The largest vertical displacement of the hyoid (1.01±0.65cm) was observed when swallowing a 10ml bolus. The hyoid showed the smallest average horizontal displacement (0.39±0.34cm), when swallowing a 3ml bolus. The average motion time of the hyoid was (2.11±0.65) seconds. It was shorter when swallowing a 10 or 20ml bolus than when dealing with a smaller one. Hyoid motion time was negatively correlated with the horizontal displacement of the hyoid bone, and the volume of a swallow was negatively correlated with the hyoid motion time but positively correlated with the penetration-aspiration scale score.
Conclusion
Bolus volume affects hyoid displacement and hyoid motion time in nasopharyngeal carcinoma patients with dysphagia after radiation therapy. For patients with a penetration-aspiration scale score of 5 or less, the optimum bolus volume is 5 to 10ml.
