城乡基本医疗保险改革的公平性研究——基于湖南省的调查

以湖南省为研究现场,从平等主义角度具体分析了新医改以来该省城乡基本医疗保险改革的公平性状况,认为目前基本医疗保险改革在一定程度上促进了基本医疗服务经济的可及性和公平性,但农村人口和城市人口在基本医疗保险受益度方面仍存在差距,应通过推进基本医疗保险制度的城乡一体化管理,逐步促进不同人群之间医疗保障的公平性。

Classification of surface EMG signals using optimal wavelet packet method based on Davies-Bouldin criterion

In this paper we present an optimal wavelet packet (OWP) method based on Davies-Bouldin criterion for the classification of surface electromyographic signals. To reduce the feature dimensionality of the outputs of the OWP decomposition, the principle components analysis was employed. Then we chose a neural network classifier to discriminate four types of prosthesis movements. The proposed method achieved a mean classification accuracy of 93.75%, which outperformed the method using the energy of wavelet packet coefficients (with mean classification accuracy 86.25%) and the fuzzy wavelet packet method (87.5%).

Neonatal maternal separation-induced changes in glucocorticoid receptor expression in posterior interpositus interneurons but not projection neurons predict deficits in adult eyeblink conditioning

Neonatal maternal separation impairs adult eyeblink conditioning. This impairment is correlated with increases in adult glucocorticoid receptor (GR) expression in the posterior interpositus nucleus [A.A. Wilber, C. Southwood, G. Sokoloff, J.E. Steinmetz, C.L. Wellman, Neonatal maternal separation alters adult eyeblink conditioning and glucocorticoid receptor expression in the interpositus nucleus of the cerebellum, Developmental Neurobiology 67 (2007) 1751–1764], a key structure in the neural circuitry controlling eyeblink conditioning. To further localize this effect, we assessed adult eyeblink conditioning and GR expression in projection versus interneurons in the interpositus of rats that had undergone standard rearing or maternal separation (1 h/day) on postnatal days 2–14. At 3 months of age, interpositus neurons were labeled with the retrograde tracer biotinylated dextran amine (BDA). After delay eyeblink conditioning, brains were processed immunohistochemically for GR and BDA labeling of interpositus neurons. GR expression was quantified in BDA-labeled and unlabeled neurons. Neonatal maternal separation impaired adult eyeblink conditioning. Control rats had significantly less GR expression in posterior interpositus BDA-unlabeled versus BDA-labeled neurons, but this difference was absent in maternally separated rats. While neonatal separation significantly increased GR expression in BDA-labeled and unlabeled posterior interpositus neurons, only GR expression in non-BDA-labeled neurons was associated with eyeblink conditioning. Thus, neonatal maternal separation may alter interneuronal modulation of interpositus output neurons, producing deficits in adult eyeblink conditioning.
