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.

Objective To understand the status of colleague support and colleague solidarity of nurses,and explore the relationship between colleague support and colleague solidarity.Methods A total of 231 nurses from Zhengzhou City were chosen using convenience sampling method to complete the questionnaire survey about colleague support and colleague sohdarity.Results The nurses' colleague support scored (76.34±2.75) totally and colleague solidarity scored (64.63±4.25) totally.In dimensions of nurses' perception of colleague support,head nurse support,support result,cooperation,sympathy establishment,awareness increasing were positively correlated with emotional unity dimension of colleague solidarity (r=0.32,0.26,0.27,0.30,0.28,all P＜ 0.05);head nurse support,support result,cooperation,awareness increasing,goal setting,action projects were positively correlated with academic unity dimension of colleague solidarity (r=0.30,0.28,0.25,0.29,0.27,0.26,all P ＜ 0.05);head nurse support,support result,cooperation,awareness increasing,action projects and process management were negatively correlated with negative views of colleague solidarity (r=-0.31,-0.27,-0.30,-0.23,-0.24,-0.27,all P ＜ 0.05).Conclusions Improving the nurse colleague-peer support can improve degree of colleague solidarity.

Objective To evaluate the value of the 7-joint ultrasound score (US7) in treatment of rheumatoid arthritis (RA) with Chinese and western medicine.Methods A total of 160 RA patients were divided into 2 groups based on different methods of treatment,including Yi Shen Qing Luo (YSQL) group and western medicine group.The patients were examined by grey scale ultrasound (GSUS) and power Doppler ultrasound (PDUS) with US7 at baseline and after 3 and 6 months later.There were 7 related joints and 5 single factors for scoring in US7 system.The joints included the wrist joints,the second/third metacarpophalangeal joints (MCP Ⅱ/Ⅲ),the second/third proximal interphalangeal joints (PIP Ⅱ / Ⅲ) and the second/fifth metatarsophalangeal joints (MTP Ⅱ/Ⅴ).And the factors included synovitis of GSUS,synovitis of PDUS,myotenositis/tenosynovitis of GSUS,myotenositis/tenosynovitis of PDUS and bone erosion (ES).Meanwhile,the laboratory index included C-reactive protein (C-RP) and erythrocyte sedimentation rate (ESR) were examined.And the clinical indexes as disease activity score in 28 joints (DAS28) were evaluated.Results The statistical differences of synovitis of GSUS,synovitis of PDUS,myotenositis/tenosynovitis of GSUS and myotenositis/tenosynovitis of PDUS scores in US7 system were found in both 2 groups at baseline,3 months and 6 months after treatment (all P＜0.01).There was no statistical difference of ES before and after treatment in all cases (P＞0.05).The factors of US7 were positively correlated with DAS28,C-RP and ESR in different extent.Condusion US7 is a viable tool for examining patients with RA.

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.

Objective:To observe the effects of low intensity pulsed ultrasound(LIPUS) on the osteogenic differentiation of rat bone marrow mesenchymal stem cells(BMSCs) on titanium surface.Methods:BMSCs from Wistar rat bone marrow were respectively cultured on the flat titanium surface and the large grain blast acid etched(SLA) titanium surface,and induced by mineralization medium.Then,the cells were interfered by LIPUS and a control condition.Alkaline phosphatase(ALP) were quantitative determinated after 3 and 7 d mineralization induction respectively,ALP staining were observed after 14 d induction.Alizarin red staining were observed after 21 d mineralization induction.Osteogenic related protein and gene expressions were detected after mineralization induction.Results:ALP in culture medium of LIPUS group was higher than that of the control group after 3 d and 7 d mineralization induction(P＜0.05).LIPUS group showed stronger ALP staining and alizarin staining,and more mineralized nodules than control group.The expression of osteogenic related proteins,including Runx2,BMP2,OPN in LIPUS group increased.Osteogenic related genes expression,including ALP,Runx2,BMP2,OPN,OCN and Col-1 of the LIPUS group increased.Conclusion:The osteogenic differentiation of BMSCs on the fiat titanium surface or SLA titanium surface can be promoted by LIPUS.

Objective To explore the feasibility of one-stop examination with Revolution CT for axial perfusion of normal pancreas.Methods Thirteen patients who received axial perfusion scan by one-stop examination with Revolution CT were analyzed as perfusion group.Two radiologists measured pancreatic CT perfusion (CTP) parameters independently and selected optimal phase for CTA and three phases of enhanced images.The effect dose (ED) was calculated.Eighteen patients who underwent abdominal enhanced CT and CTA with spiral scan were included as control group.Patients in both groups had no pancreatic disorders.The interobserver variation of CTP parameters was estimated.Two independent radiologists separated the superior pancreaticoduodenal artery (SPDA) image into 5 points according to image quality,and the consistency was assessed.The subjective points of SPDA image quality of two groups was compared.CT value,images noise,CNR and SNR of SPDA on CTA images and those of pancreas on three phases enhanced scan images between two groups were compared.Results ICC values of all CTP parameters were higher than 0.75.The ED of perfusion protocol was (24.52±-0.01)mSv.The subjective image scores of SPDA on CTA images in both groups were both 5,the consistency was good (Kappa=0.629,0.769).The CT value,CNR,and SNR of SPDA on CTA images of CTP group were higher than those of control group (all P＜0.05).The CT value,CNR,and SNR of pancreas of CTP group were higher than those of control group in venous phase and balanced phase (all P＜0.05).Conclusion The pancreatic CT one-stop examination can be performed by Revolution CT scanner with maximum detector width with acceptable radiation dose,from which pancreatic CT perfusion data,enhanced images with high quality and better CTA images can be extracted.

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 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.
