Objective To reveal the prevalence of depressive and/or anxiety symptom and disorder in patients with awareness during general anesthesia.Methods 10 patients which had the awareness during general anesthesia were selected into AR group (awareness with recall during general anesthesia group).Face-to-face interviews were used in data collection together with the self-completed HAD scale for depressive and/or anxiety symptom screening.Subjects getting a HAD score of 9 and above were further assessed for depressive and/or anxiety disorders with HAMA scales and HAMD scales.Results The difference of common general state of patients, such as age, weigh and the time during operation were all insignificant between two groups (p>0.05).The rate of patients received general anesthesia only in AR group was higher than that in control group(p<0.05).The prevalence of depressive symptom, the prevalence of depressive or anxiety symptom and the prevalence of depressive and anxiety symptom in AR group were higher than that in control group(p<0.05).The prevalence of depressive disorder, the prevalence of depressive or anxiety disorder and the prevalence of depressive and anxiety disorder in AR group were higher than that in control group too(p<0.05).Conclusion There was high prevalence of depressive and/or anxiety symptom and disorder in patients with recall-awareness during general anesthesia.

Objective:To explore the correlations between self-esteem and life satisfaction in elementary school students. Methods:494 elementary school students were measured with CSES (Children's Self-Esteem Scale) and BMSLSS (Brief Multidimensional Students' Life Satisfaction Scale). Results: (1) There were significant gender and grade differences on self-esteem in elementary school students. Girls got higher scores(Means were 3.8?0.8?3.8?0.9?3.9?0.8)than boys on achievements, discipline and social morality-help(Means were 3.5?0.9?3.2?0.8?3.6?0.9,F=17.2?47.0?16.6, P

Objective: To compare the differences between urban and rural middle school students on life satisfaction. Methods: 1152 urban and rural middle school students were measured by Multidimensional Students'Life Satisfaction Scale ( MSLSS - CV) . Results: ( 1 ) The urban students had higher scores than their rural counterparts on all the satisfaction dimensions ( mean value differences = 0. 2 - 0. 4. For example, the family satisfaction of urban and rural students were 4. 6?1. 0, 4. 2?1.0 respectively, mean value difference =0. 4; the serf satisfaction of urban and rural students were 4. 6?0. 7 , 4. 4?0. 7 respectively, mean value difference = 0. 2 ) . ( 2 ) The mean values rank (from high to low) of the five dimensions on the satisfaction was family, self, friend, school and living environment in urban students. The mean values rank (from high to low) of the five dimensions on the satisfaction was self, family, friend, school and living environment in rural students. (3 ) The difference between city and countryside had higher explained percentage than popularity on all the satisfaction dimensions. The percents were as follows: 5% , 10% , 4% , 6% , 17% , 11%. Conclusion: There were significant differences on life satisfaction between urban and rural middle school students.

[Objective]To observe the effects of chronic renal failure (CRF)on hearing and investigate its mechanism.[Methods] Twenty-nine male wistar rats were randomly divided into four groups:Ⅰthe normal rats as control for 12 days (n=6); Ⅱrats given adenine(ig) for 12 days (n=8); Ⅲthe normal rats as control for 24 days (n=6);Ⅳ rats given adenine(ig) for 24 days(n=9). The rat model of CRF was produced by being perfused of adenine [300mg/kg]for 12d and 24d. Brain-stem auditory evoked potential(BAEP) was utilized to evaluate the auditory function and renal tissue morphology was observed; Serum sampling was used to determine the content of Cr, BuN. The expression of NOSⅡin the cochlear was measured by immunohistochemical technique.[Results] After adenine given for 12d or 24d, the Cr and BuN were in significant higher level than that in control group. The BAEP thresholds were gradually higher than that in control group, the BAEP delitescence prolonged. Light microscopic observation of renal tissue showed that the degree of fibrosis was gradually higher. Data of immune histochemistry about the cochlear tissue showed that the expressions of NOSⅡ were feebly positive in the cochlear vassal texture, inner-outer hairy cell and helical-ganglion cell, and following functional damage of the kidney, their expressions reinforced gradually, amongst which strongest expression was vassal texture, the next helical-ganglion cell, the last inner-outer hairy cell.[Conclusion]CRF can result in deafness. It is likely concerned with toxic effects of the metabolizable substance, the metabolizable dysfunction of the electrolyte, shortage of trace elements, etc. One of the important mechanisms of the effects of CRF on hearing is the toxic damage of NO to cochlea.

This paper presents a feature extraction method based on multivariate empirical mode decomposition (MEMD) combining with the power spectrum feature, and the method aims at the non-stationary electroencephalogram (EEG) or magnetoencephalogram (MEG) signal in brain-computer interface (BCI) system. Firstly, we utilized MEMD algorithm to decompose multichannel brain signals into a series of multiple intrinsic mode function (IMF), which was proximate stationary and with multi-scale. Then we extracted and reduced the power characteristic from each IMF to a lower dimensions using principal component analysis (PCA). Finally, we classified the motor imagery tasks by linear discriminant analysis classifier. The experimental verification showed that the correct recognition rates of the two-class and four-class tasks of the BCI competition III and competition IV reached 92.0% and 46.2%, respectively, which were superior to the winner of the BCI competition. The experimental proved that the proposed method was reasonably effective and stable and it would provide a new way for feature extraction.

Nowadays, normal humidifier is used to heat and humidify the gas before sending to ventilator tube. A new type of ventilator which offers both breathing tube with heater and humidifier is incorporate. In the light of this, patients already bought ventilator still confront this problem. Therefore, this paper mainly introduces a new manufactural method which is controlling the temperature and humidity of gas sent by breathing machine online by a temperature controller which consist of Silica gel hotline and microcomputer. As a matter of fact, the controller is adaptable in various types of breathing tube and can accurately control the humidity and temperature of gas sent into bodies.
