Correlations between occupational burnout and humanistic care ability of the nurses in our hospital / 现代临床护理

Objective To study current situations of occupational burnout and humanistic care ability of the nurses in our hospital and explore the relationship between them. Method Nursing burnout scale (NBS) and caring ability inventory(CAI) were adopted in the investigation among 542 nurses in our hospital. Results The total score on the nursing burnout of the nurses of my hospital was 96 to 214, with an average of (155.04 ± 17.01). The burnout among 245 of them (45.20%) was in mild to moderate degree and that among 155 of them (28.60%) in a severe level. The score on humanistic care ability was 94 to 253 with an average of (178.14 ± 23.66). The ability among 46.31%of them was at a middle level and that among 25.46%of them at a low level. The occupational burnout of the nurses was negatively correlated with their humanistic care ability as well as with its three dimensions of cognition, courage and patience (P<0.01). Conclusions The occupational burnout can be alleviated by reducing the pressure in their caregiving practice. Their humanistic care ability can be enhanced by improving humanistic care nursing education and bettering humanistic care system.

Physiological drift of teeth in upper arch after bi-maxillary first premolar extraction / 中华医学美学美容杂志

Objective To study the distance and pattern of the movement of the maxillary teeth after 6 months driftodontics for dental crowding.Methods 20 dental crowding children,according to the treatment plan,who were required to removal four first premolars,were involved in this study (8 males,12 females,aged 11-14 years old).All of the children did not wear appliance in six months after teeth extraction.X-ray image data before and six months after teeth extraction were collected.The width of extraction space,the anterior irregular index and inclination of the axis of each tooth were recorded before and six months after tooth extraction.The data were analyzed by t-test and Pearson relative analysis.Results The study model showed that bilateral maxillary space of extraction pre-and pro-driftodontics decreased (5.79 ± 4.9) mm (P ＜ 0.01) ; anterior crowding decreased (5.79± 4.12) mm,irregular index was significantly reduced (P＜0.01).Cephalometric film measurement showed that canine crown moved distally (4.87±3.54) mm after the drift (P＜0.01).Canine tooth axis changed from mesial to upright.The crown of maxillary first molar moved mesially (1.18± 0.52) mm (P ＜ 0.01).There were no significant changes in apical position.Conclusions After 6 months of the physiological drift,upright moving of canine relieves anterior teeth crowding.The molar anchorage is saved.

Expressions of N HERF1 and β-catenin in primary extramammary Paget's disease tissue and their significance / 中华皮肤科杂志

Objective To investigate the expressions of Na+/H+ exchanger regulatory factor 1 (NHERF1) and β-catenin in extramammary Paget's disease tissue as well as their significance.Methods Immunohistochemistry was performed to detect the protein expressions of NHERF1 and β-catenin in paraffin-embeded tissue samples from 18 patients with in situ and 22 patients with invasive extramammary Paget's disease.Results There was a high expression of NHERF1 protein in 18 (81.82％) invasive and 7 (38.89％) in situ extramammary Paget's disease samples (x2 =7.78,P ＜ 0.01).Statistical differences were observed in the membrane expression rate and cytoplasmic or nuclear expression rate of β-catenin between invasive and in situ extramammary Paget's disease tissue samples (0 (0/22) vs.33.33％ (6/18),x2 =8.63,P ＜ 0.01; 81.82％ (18/22) vs.44.44％ (8/18),x2 =6.08,P ＜ 0.05).In extramammary Paget's disease in situ tissue samples,the expression of NHERF1 was negatively correlated with the cytomembrane expression of β-catenin (ρ =-0.488,P ＜ 0.01),but positively correlated with the cytoplasmic or nuclear expression of β-catenin (ρ =0.623,P ＜ 0.01),and there was a negative correlation between the cytomembrane and cytoplasmic or nuclear expression of β-catenin (ρ =-0.572,P ＜ 0.01).Conclusions There is an abnormal expression of NHERF1 and β-catenin in extramammary Paget's disease tissue,which may be associated with the initiation,progression,and invasion of primary extramammary Paget's disease.

Comparison of tongue postures at rest position between anterior cross-bite and normal bite / 中华医学美学美容杂志

ObjectiveTo compare tongue positions at rest between normal occlusion people and patients with anterior cross-bite malocclusions,and to explore whether there is any abnormality in the tongue position of the anterior cross-bite malocclusions.Methods Twenty adults of normal bite (8 males and 12 females,with an average age of 23.8 years) and 20 adults of anterior cross-bite (1 1males and 9 females,with an average age of 24.6 years) were involved in this study.The position habits of tongue were investigated by a questionnaire.The tongue positions,which were enhanced by applying barium to tongue and palatal surface,were compared by cephalometric roentgenogram.Two groups were compared by t-test to determine the variation of anterior cross-bite. Results In normal occlusion group,the dorsum of tongues was sealed with all palatal surfaces except uvula site.In anterior cross bite group,tongues were far from palate,and were difficult to lift.The profile of tongue showed standing upright forward and up in normal occlusion group,while inclining back and low in anterior cross-bite group.The tops of tongue dorsum sites were at the border of soft and hard palate in normal occlusion group.While in anterior cross bite group,the tops of tongue dorsum sites were at the border of uvula and soft palate.In anterior cross-bite group,the tongue-to palate distance was bigger than that of normal occlusion group (P＜0.01).However,both length and height of the tongue had no significant differences between two groups (P＞0.05).ConclusionsIn anterior cross-bite patients,tongue positions were lower than that of normal occlusion people.

Induction of amelogenin in formation of hard tissues in dental pulp / 吉林大学学报(医学版)

Objective To study the induction of amelogenin in formation of hard tissues in the pulp tissues,to provide experimental foundation for research in formation of hard tissues induced with amelogenin.Methods Sixteen male Wistar rats were divided into control group and experimental group.Cells and matrix structures and amelogenin expression in the growing ends of cyclophosphamide(CP)-affected incisors were examined by histological and immunohistochemical methods.Results Experiment group:extensive edematous changes were noted in the apical pulp tissue of the incisor associated with disappearance of odontoblasts facing to presecretory and secretory ameloblasts. The cell layer of young ameloblasts was therefore lined directly with pulp tissue in which some osteodentin-like tissue was present near the ameloblasts. Immunoreactions for amelogenins were observed in the labial side of the pulp,particularly around the newly induced hard tissues in the affected region. Conclusion Amelogenins has induction in formation of hard tissues in dental pulp following the inhibition of formation of odontoblasts by CP.
