Objective To evaluate the efficacy of flexible laryngeal mask airway and sevoflurane in pediatric strabismus surgery. Methods Totally 60 children undergoing elective strabismus surgery were recruited and divided into two groups with 30 cases each by random digits table:group T, in which children accepted endotracheal tube intubation and combined intravenous and inhalation anesthesia with mechanically ventilation; and group F, in which children adopted both flexible laryngeal mask airway and inhalation anesthesia of sevoflurane with spontaneous breath. Airway peak pressure (Ppeak), average airway pressure (Pmean), blood pressure (Bp) and heart rate (HR) at induction (T1), 1 min (T2), 3 min (T3) and 5 min (T4) after induction, removal of endotracheal tube or laryngeal mask airway (T5), awaking time and extubation time, occurrence of cough, dysphoria and pharyngodynia from being awake to extubation, satisfaction of patients were recorded. Results When compared to baseline, systolic pressure was lower at T, and higher at T2, T3 and T5, and HR was higher at T2-T5 in group T(P< 0.05),Bp was lower at T1-T4 in group F (P < 0.05). Bp and HR at T2-T5 in group F were lower than those in group T (P < 0.05). The awaking time was (8.1 ?2.6) min, the extubation time was (12.6 ?3.2) min, the occurrence of cough and pharyngodynia was 66.7%(20/30), 40.0%( 12/30), the dysphoria (0-1 score) was 7 cases in group T,(5.2 ± 1.1) min, (6.3 ± 1.5) rain,0,6.7%(2/30),25 cases in group F. There were significant differences between two groups (P<0.05). The satisfaction of patients in group F was higher than that in group T, there was significant difference between two groups (P< 0.05). Conclusion Flexible laryngeal mask airway with sevoflurane could offer high efficacy in pediatric strabismus surgery.

Objective To evaluate the effect of multiple-mode analgesia consists of epidural administration of lidocaine,parecoxib intravenously and patient-controlled epidural analgesia (PCEA) on patients after thoracic surgeries. Methods Total 90 patients treated with thoracic surgeries were allocated into 3 groups by random digits table,each with 30 cases. Patients accepted 1% lidocaine 5 ml epidurally 5 min before incision in group A and B,and 5 ml saline as control in group C. When chest closing parecoxib 40 mg were given in group A,and 2 ml saline as control in group B and C. All the patients were given PCEA. Postoperative hemodynamics,dosage of remifentanil and analgetics of PCEA within 48 h, visual analogue scale (VAS) of pain, rescue of pethidine, duration for first pain calling,and satisfactory scores of patients, doctors and nurses were recorded. Results Dosage of remifentanil was lower [(0.72±0.26), (0.84±1.20) μg／(kg·min)], and duration for first pain calling was longer[(35.00±2.78),(12.09±6.27) min] in group A and B than that in group C significantly[(1.80±0.84) μ,g／(kg·min) and (5.95±3.65) min](P<0.05). Analgetics of PCEA with in 48 h in group A was lower than that in group B which was lower than that in group C[(180.40±20.48), (192.54±40.15), (220.26±36.78) ml](P< 0.05). No difference was found on VAS of pain and hemodynamics among three groups when patients were kept immobilized, but VAS of pain in group A and B was lower than that in group C when patients kept moving. Satisfactory scores of patients,doctors and nurses in group A were higher. Conclusion Epidural administration of 1% lidocaine combined with intravenous paiecoxib 40 mg and PCEA an offer satisfactory postoperative analgesia for patients after elective thoracic surgeries.

Objective To Evaluate the efficacy and safety of Qingre-Huoxue Recipe ( QHR ),Qingre -Huoxue Recipe and Methotrexate(QHR+MTX) in improving clinical symptoms of dampness-heat and blood-stasis syndrome of rheumatoid arthritis.Methods According to multi-center,randomized,and control intervention design,142 RA patients were randomly divided into QHR group (71 cases) and QHR+MTX group (71 cases).With clinical symptoms as evaluation indexes,FAS set and PP set were adapted for analysis.Results FAS set analysis:Both groups can significantly reduce pain VAS score [ (4.82 ± 1.98) vs (4.31 ± 1.85) ],reduce tenderness and swollen joint number[(4.87±4.05)vs(4.20±3.36)、(8.72±6.24)vs(7.14±5.03)respectively],shorten morning stiffness [ (39.56 ± 46.68) min vs (36.65 + 42.58) min] and significantly reduce the symptoms of fatigue[ (4.13 ±2.34) vs (3.74 ±2.20) ],also with good security.But there was no statistically significant difference between the two groups.Conclusion Qingre-Huoxue Recipe with MTX had no significant advantage in improving clinical symptoms in patients with the dampness-heat and blood-stasis syndrom of RA than without MTX.

Objective:To investigate the criterion-related validity of Menopause-Specific Quality of Life Questionnaire (MENQOL)-Chinese version and to evaluate the effect of menopausal symptoms on health related quality of life. Methods:This study was a cross-sectional survey. Three communities were randomly chosenin Changsha,and then 340 menopausal women aged 45-55 years were randomly chosen from the documented data of the 3 community health service centers. They were required to fill out 4 questionnaires: demographic questionnaire, MENQOL-Chinese version, Kupperman Index (KI) and World Health Organization Quality of Life (WHQOL)-BREF. Correlation analysis was used to measure the criterion-related validity. Results: MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) and KI total score were positively correlated (r=0.800,0.751, 0.607, 0.906 respectively); while negatively correlated with WHOQOL-BREF total score (r =-0.694,-0.851,-0.585,-0.873 respectively); MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) were signiifcantly correlated with WHOQOL-BREF subscales (physical, psychological, social relationship, environment), and the physical domain was the highest among the correlation coeffcients (r=-0.915). Conclusion:MENQOL-Chinese version shows relatively high criterion-related validity compared with KI and WHOQOL-BREF, which can be widely used to measure the quality of life of menopause women in China.
