Objective To understand the application status of physical assessment in clinical nurses. Methods Using self-designed physical assessment skills questionnaire to investigate nurses in six provinces of China, 1115 questionnaires were valid. Results There were 171 items in this questionnaire,4.0% of them were used regularly, 19.3% used frequently, 76.7% used occasionally. The result of Spearman correlation showed that there was positive correlation between the frequency of physical assessment skills and the subjective needs of nurses, regional, educational background, hospital level. There was also negative correlation with title, age and seniority. Conclusions The main factors lead to imbalance development of physical assessment skills are regional, hospital-level and education background; the assessment skills of specialist hospitals and wards need to be standardized immediately.

Objective To understand the subjective perception and influential factors of physical assessment technique in clinical nurses. Methods Using self-designed physical assessment skills questionnaire to investigate nurses in the six provinces of China, 1115 questionnaires were valid. Results There were 11 items in this questionnaire. The first four were: physical assessment is an essential skill of nurses (88.1%),the importance of continuous learning (84.8%), lack of maturity assessment tools (79.8%), heavy workload,lack of time (60.8%). The result of multiple regression analysis (stepwise) showed that hospital-level and regional were the main factors affecting the subjective perception. Conclusions The development of physical assessment reies mainly on rational allocation of human resources structure, establishing the physical assessment framework, and make sure different departments have their own characteristics and the importance of continuing education.

OBJECTIVETo explore biomechanical properties and stress-strain of mucosa scars after cleft palate surgery.

METHODSAfter the model of mucosa scars was made, the mucosa scars and normal mucosa were excised and examined immediately by tensionometry.

RESULTSThe mucosa scars after cleft palate surgery were compared with normal mucosa. The Poisson's ratio of mucosa scars and normal mucosa was 0.5 and 0.49, respectively, showing no significant difference between the two groups. The ultimate Young's modulus of mucosa scars was about 24.22 MPa, however, it declined to 3.32 Mpa in normal mucosa.

CONCLUSIONSThe mucosa scars after cleft palate surgery are biomechanically weaker than normal mucosa. It can be used for further research, such as maxillary orthognathic surgery, distraction osteogenesis, and orthodontic treatment.
