Objective To investigate how surgical patients are assessed regarding pressure ulcer risks and the usage of evaluation tools in different stages during perioperative period.Methods Totally 210 nurses from operating rooms and surgical wards in 7 tertiary hospitals of Jiangsu Province were investigated with self-designed questionnaire.Results Operating room nurses of 7 hospitals used different kinds of scales for pressure ulcer risk assessment,the same scale document was used during the different stages of operation,the frequency and time for pressure ulcer risk assessment varied from one to three times,preoperative visit to handover in surgical ward were different;the Braden scale was used by surgical nurses to evaluate pressure ulcer risk after operation,while most surgical nurses believed that the existing scale lacked specificity and intraoperative risk factors that should be considered when assessing postoperative patients.Conclusion The frequency and time of pressure ulcer risk assessment of patients during perioperative period are not standardized,the content of scale is limited and lacks specificity,the assessment of pressure ulcer risk during perioperative period is discontinuous and non-dynamic.There are no specific risk assessment scales targeting preoperative,intraoperative and postoperative pressure ulcer risk assessment.

BACKGROUND:The micro-ecological environment has been broken when the ocular prosthesis was inset into the conjunctival sac. The recede of self cleaning function is more conducive to the microbial growth and colonization. The cleaning of plaque biofilm on ocular prosthesis surface affects the patient's wearing comfort and quality of life. It is necessary to seek an effective cleaning method. OBJECTIVE:To compare the clearance effect of five cleaning methods on the palque biofilm on ocular prosthesis surface. METHODS: The conjunctival secretions from 84 patients who were subjected to ocular prosthesis repair were taken for bacterial culture and identification. Fifty pieces of self-curing resin and thermosetting resin artificial eyes were produced. The artificial eyes in each group were randomly divided into five groups, and were cleaned respectively with clear water, volume fraction of 75% ethanol, Boston SIMPLUS, polident and toothpaste. After the completion of the cleaning, the test piece was conducted residual biofilm culture. The clearance effects of different processing modes were evaluated using colony counting method. RESULTS AND CONCLUSION: Eighty-four specimens were submitted for inspection, of which 49 were positive. The Staphylococcusaureus separation rate was 14.29%.Staphylococcus epidermidis separation rate accounted for 13.10%. Maxwel Corynebacterium separation rate accounted for 7.14%. When water, Boston SIMPLUS and toothpaste were used for cleaning, theStaphylococcus aureus colony number in the self-curing resin group was higher than that in the thermosetting resin group (P< 0.05); when ethanol and polident were used for cleaning, there was no difference in the Staphylococcus aureus colony number between these two groups. In self-curing resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). The colony count in the ethanol treatment group was lower than that in the Boston SIMPLUS group (P < 0.05). There was no significant difference in the colony count between other groups. In thermosetting resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). There was no significant difference in the colony count between other groups. These results demonstrate that ethanol, Boston SIMPLUS, polident and toothpaste have better cleaning effects onStaphylococcus aureusbiofilms on the surface of two kinds of ocular prostheses than the clear water rinse. Overal, it is encouraged to clean the artificial eyes using polident and Boston SIMPLUS, in order to avoid the occurrence of microbial infection in the conjunctival sac after wearing ocular prosthesis.

Objective To observe the effect of different energy levels of pulsed Nd∶YAG laser irradiation on the changes of NO and NOS levels in ulcer tissue of oral ulcer model.Methods Forty-eight Sprague-Dawley rats were inflicted with oral ulcer,and then randomly and equally assigned to 6 groups,that is,oral ulcer group,1% iodine glycerin group and the rest 4 groups receiving pulsed Nd∶YAG laser irradiation at 1.5 W 40 mJ,1.5 W 60 mJ,1.5 W 80 mJ or 1.5 W 100 mJ(once per day,for 3 consecutive days).The other 8 rats served as normal control.In 24 h after last treatment,4 rats from each group were sacrificed and their cheek pouches were taken out for NO and NOS levels in the mucosal tissue by spectrophotomentry.Ulcer healing were observed 24 h after the last treatment for 8 consecutive days.The efficiency of Nd∶YAG laser irradiation at different powers were evaluated.Results Irradiation groups had significantly shorter healing time compared with iodine glycerin group.Level of NO and NOS activity in 1.5 W 60 mJ and 1.5 W 80 mJ groups was evidently lower than the ulcer group(P
