Patient′s expectation has been defined as the anticipation that given events were likely to occur during, or as an outcome of, health care. What people expect from their health care are potentially important in predicting patient satisfaction and dissatisfaction with their care, treatment and health outcomes. There was widespread recognition of the importance of evaluating services from consumer perspectives. In this article, domestic and foreign research in recent years, expectations status, significance and various influencing factors in relation to the expectations in processes of health care were summarized. Consumer evaluations of their health care are now an established component of quality assessment, planners need to understand the expectations underlying patients′views in order to interpret their feedback. Thus leading to improve patient satisfaction and the social evaluation of medical units.

BACKGROUND:The cross-linking reagent is the main unit to support the skeleton of molecularly imprinted polymers, which is closely related to the bio-friendly adaption of polymers. The biocompatible and biodegradable capacities of common crosslinking agents are unclear.
OBJECTIVE:To prepare a novel biodegradable molecularly imprinted polymer and to evaluate the adsorption and biodegradability properties of the polymer.
METHODS:The biodegradable molecularly imprinted polymer was synthesized with the acrylated polyε-caprolactone as the cross-linking reagent under the UV polymerization. The adsorption of the polymer was evaluated by adsorption isotherm, Scatchard analysis and kinetic curves. The biodegradation of the polymer was observed in the simulated physiological environment system in vitro.
RESULTS AND CONCLUSION:Both the molecularly imprinted polymer and non-molecularly imprinted polymer showed an adsorption effect on theophyl ine, the template. But the adsorption amount of the molecularly imprinted polymer was significantly more than that of the non-molecularly imprinted polymer. The drug loading and encapsulation efficiency of the molecularly imprinted polymer were 1.54%and 12.48%, respectively. The degradation rates of molecularly imprinted polymer and poly(ε-caprolactone) diol were 6.60%and 1.33%, respectively, within the observation time in vitro. The obtained molecularly imprinted polymer not only exhibited specific adsorption to certain molecules but also showed good biodegradable properties in the simulated physiological environment system, which is necessary to be a potent drug carrier.

Objective To extract principal components from valuable indicators on conventional ultrasoundand contrast-enhanced ultrasound (CEUS) in the differential diagnosis of thyroid benign and malignant lesions and to discuss the diagnostic value of each indicator.Methods One hundred and three patients with 125 thyroid lesions (65 malignant lesions and 60 benign lesions) underwent preoperative grayscale ultrasound (GSUS),color Doppler ultrasound (CDUS) and CEUS examinations.Eighteen indicators were chosen to evaluate every lesion and principal components were extracted by principal component and valuable indicators were ordered by importance.Results There were significant differences on GSUS and CEUS indicators between benign and malignant lesions.The first principal component was the representation of contrast enhanced ultrasound and was valuable in the differential diagnosis of thyroid benign and malignant lesions.The rank of valuable CEUS indicators were homogeneity of enhancement,filling defect,relative arrival time of periphery,peak interior echogenicity,relative arrival time of interior,peak peripheral echogenicity and ring enhancement.Conclusions GSUS and CEUS are valuable in the differential diagnosis of thyroid benign and malignant lesions.

Objective To investigate the discriminant analysis model of gray-scale ultrasound (GSUS),contrast-enhanced ultrasound (CEUS) and the combination of them in the differential diagnosis of benign and malignant thyroid lesions and the diagnostic values.Methods Ultrasound images of 211 thyroid lesions confirmed by pathology were synthetically reviewed by scoring 5 GSUS indicators including shape (X1),orientation (X2),interior echogenicity (X3),halo sign (X4),and microcalcification (X5),as well as 6 CEUS indicators including relative arrival time of microbubhles in the periphery (X6) and interior (X7),peak periphery (X8) and interior (X9)echogenicity,peripheral ring-enhancement (X10),homogeneity of enhancement (X11).The diagnostic models with their values of GSUS,CEUS and the combination of them were explored by discriminant analysis.Results The discriminant analysis function of GSUS in the diagnosis of thyroid benign and malignant lesions was g1 (X) =0.715 X1+0.276X2 + 1.028X3 +1.197X4 +0.923X5-2.202 with the diagnostic value 86.3％,the discriminant analysis function of CEUS was g2(X) =-0.392X6 +0.541X7-0.117X8 +0.562X9 + 1.173X10 +2.200X11-1.956 with the diagnostic value 89.1％,and the discriminant analysis function of the combination of GSUS and CEUS was g3 (X) =0.418X1 + 0.173X2 + 0.626X3 + 0.558X4 + 0.183X5-0.476X6 + 0.474X7-0.071X8 + 0.399X9 + 0.985X10 +1.639X11-2.530 with the diagnostic value 91.0％.Conclusions GSUS and CEUS were valuable in the differential diagnosis of benign and malignant thyroid lesions,and the combination of GSUS and CEUS was most valuable.

Objective To study the difference of attentional bias towards general negative words between non-mediated obsessive-compulsive disorder (OCD) patients and healthy controls.Methods Event-related potentials (ERPs) were collected from 26 non-mediated OCD patients and 24 normal controls while they performed an emotional Stroop task.Results Compared to healthy controls,OCD patients showed significantly longer reaction time (OCD:(467 ± 14.88) ms,Controls:(409.65 ± 15.49) ms,P＜ 0.01),and had significantly larger P2 and P3 amplitude to all three types of words (P2 amplitude:OCD:(10.41±0.49) μV,Controls:(8.89±0.48) μV,P＜0.05;P3 amplitude:(10.04±0.68) μV,Controls:(7.68±0.67) μV,P＜0.05).In addition,the P2 peak latency of the frontal area in OCD patients was significantly longer than that in healthy controls(OCD:(190.09±4.71) ms,Controls:(179.60±4.72) ms,P＜0.05).Conclusion Current findings suggest that OCD patients are characterized by a general attentional inhibition deficit but not an attentional bias to the negative words.

Objective To explore the application of submental ultrasonongraphy (SUS) in the assessment of oropharyngeal swallowing disorders in children with cerebral palsy.Methods Seventeen children with cerebral palsy and oropharyngeal swallowing difficulties (7 on nasal feeding,10 on oral feeding) constituted the treatment group while 20 normal counterparts formed the control group.SUS was applied to measure any changes in the thickness of the tongue muscle and the range of hyoid bone displacement when they swallowed 5 ml of water.The results were compared with those assessed using the functional oral intake scale to decide the best cut-off point for detecting tube-feeding-dependent dysphagia.The intraclass correlation coefficient (ICC) of the 20 children in the control group was calculated to evaluate the intra-rater and inter-rater reliability of SUS.Results The average tongue muscle thickness change and hyoid bone displacement amplitude of the children on nasal feeding were significantly smaller than those of the children without nasal feeding and the normal children.The best cut-off point for the tongue muscle thickness change data was 1.0 cm,and that of the hyoid bone displacement amplitude was 1.5 cm.All of the ICCs were above 0.4,indicating good intra-rater and inter-rater reliability for the SUS examination.Conclusion Submental ultrasonongraphy can help assess the swallowing function of children with oropharyngeal swallowing disorders.
