Objective:To evaluate the validity and reliability of the Chinese version of the Eating Disorder Examination Questionnaire 6.0 (EDE-Q 6.0) in female patients with eating disorders.Methods:A total of 239 patients with eating disorder and 142 healthy controls who were recruited consented to participate in the study and completed Chinese EDE-Q 6.0.Confirmatory factor analysis was used in patients to compare the original 4-factor model,1-factor model and 3-factor model.The criterion validity was tested with the Eating Disorder Inventory (EDI).Mann-Whitney U analysis was used to compare the differences of EDE-Q 6.0 scores on the two samples to test the empirical validity,and ROC analysis was used to determine the cut-off value.The internal consistency of the scale was tested in two samples.Among all participants,89 patients and 31 healthy controls were retested 1 month later.Results:The original 4-factor model fit better than the other two.The EDE-Q 6.0 total score and the EDI total score had a high consistency in the total sample,patients and controls,respectively (ICC =0.88,0.87,0.73).Patients had higher scores on the EDE-Q 6.0 than controls (Ps ＜0.01).The mean area under the curve (AUC) of EDE-Q 6.0 was 0.91,the optimal cut-off point of EDE-Q 6.0 was total score ≥ 1.27,sensitivity and specificity were 79.4％ and 88.2％ respectively.The Cronbach α coefficients were 0.95,0.91,and 0.88 for the total sample,patients and controls respectively.The test-retest reliabilities were 0.73 for the total scale,0.58,0.68,0.69 and 0.71 for the 4 factors.Conclusion:The Chinese version of the Eating Disorder Examination Questionnaire 6.0 have good psychometric properties and diagnosis accuracy,and it could be used to assess the severity of clinical symptoms.

OBJECTIVETo study the effects of inhalation enflurane (Enf) before aortic clamping on myocardial reperfusion injury in cardiac surgery with cardiopulmonary bypass (CPB).

METHODShirty patents undergoing selective cardiac valve replacement were randomly allocated to three groups. Group I and group II inhaled 1.0 MAC and 0.5 MAC Enf before clamping aorta, respectively. Group III was the control group interval administration with Fentanyl.

RESULTSImmediately upon aortic clamp release (T2), the value of CK-MB, MDA and SOD of all the groups was significantly increased, however,their concentration did not peak significantly until T3 and T4(10 and 30 min after clamp aorta release). The levels at 60 min (T5) and 24 hours (T6) aorta were lower than T4 but still higher than T(0). At T3 and T4, CK-MB levels in group I were significantly higher than those in II and III groups (P=0.0220, 0.0108 and 0.0202, 0.0295). At T6, the CK-MB level of group II was significantly higher than that of group III (P<0.0001). At T4 and T5, the MDA value of group I was higher than that of group II (P=0.0060 and 0.0364). Meanwhile, the SOD level in group I was also higher than that of group II and group III at the T4 point (P<0.0001 and 0.0084). There was a correlation between the CK-MB value and the aorta clamping time,correlation coefficient range being 0.55 - 0.81,(P<0.05). However, there was no correlation between the CK-MB and MDA, SOD.

CONCLUSIONThere is ischemia reperfusion injury during cardiac surgery CPB with the increase of OFR production and elevation of the antioxidant reserve. Inhalation of large dose of enflurane may result in increased myocardial ischemia reperfusion injury manifested by elevated levels of myocardial enzymes and OFR production.
