ABSTRACT
<p><b>OBJECTIVE</b>To develop a brief version scale with good validity and reliability to evaluate self-management knowledge, attitude and behavior (KAB) of diabetes patients in a shorter time.</p><p><b>METHODS</b>20 authority experts who specialized in the field of diabetes clinical and non-communicable disease self-management, and familiar with the relevant content of diabetes self-management were selected. Face to face and Email consultation methods were applied in two rounds delphi expert consultations to choose items from the Diabetes Self-management Knowledge, Attitude, and Behavior Assessment Scale (DSKAB, total scale, 98 items). In the first round of expert consultation, experts were asked to select the core items from every dimension and score the extent of familiarity and basis of judgment. In the second round of expert consultation, the significance of the core items which were selected by experts in first round, were graded. The items which entered into the brief scale were determined by harmonious condition of expert opinions.</p><p><b>RESULTS</b>Two rounds of consultation reclaimed 16 and 15 responses respectively, Positive coefficients of experts were 80% and 94% respectively, and both authoritative coefficients were 0.90. In the first round of consultation, experts selected 44.3 ± 6.2 items on average, 42 items were selected according to the integrity of the scale for measuring dimension and content at last. In the second round of consultation, experts thought that the 42 items could measure the important contents of each dimension comprehensive and representative, the item importance scores of knowledge, attitude, and behavior subscale were 8.42 ± 1.17, 8.61 ± 1.24, 8.61 ± 1.02 respectively, and the coordination coefficients of the three subscale were 0.36, 0.20, 0.49 (χ(2) were 89.74, 11.13, 96.03, P<0.05). The total coordination coefficient was 0.38 (χ(2) =199.36, P<0.001), which indicated the concentration of experts(')opinion was acceptable, showed the brief scale with good face validity and content validity.</p><p><b>CONCLUSION</b>The brief scale could evaluate Diabetes Self-management KAB Scale rapidly and relatively comprehensive in groups or individuals diabetes with good face validity and content validity.</p>

BACKGROUND:Studies have shown that sacral nerve-root stimulation based on anodes block technique can effectively reconstruct the bladder voiding function of the rabbits with spinal cord injury. But the corresponding technology of stimulating electrode has not been reported so far. OBJECTIVE:To design and develop the stimulating electrodes matching with both rabbit sacral nerve roots and anodal blocking technique, to observe the ultrastructure and morphological change of rabbit sacral nerve roots which implanted in electrode stimulation for a long-term and to assess the safety of stimulating electrodes. METHODS:Thirty New Zealand rabbits were included, 10 rabbits were randomly selected from them and sacrificed after anesthesia, and then cut the anterior roots of bilateral S 2 and S 3 immediately;after measuring the diameter under the light microscope, the sleeve type stimulation electrode matched with the diameter was made. The remaining 20 rabbits were randomly divided into control group and implantation group, with 10 rabbits in each group. In the implantation group, the stimulating electrodes were implanted into the forepart of S 2 and S 3 nerve roots after anesthesia, and then sacrificed after fed for half a year for col ecting the samples. Then ultrastructure change of sacral nerve roots with the implantation was observed. RESULTS AND CONCLUSION:Structure of nerve cel s of sacral nerve roots remained in good condition under a light microscope after long-term implantation of the stimulating electrodes. No obvious degeneration of axons, no inflammatory infiltration and glial scar formation were observed. In the implantation group, myelins arranged closely without demyelination phenomenon, and there was no atrophy of neuronal nuclear, no nuclear sag, no increased nuclear decompression and heterochromatin in neurons under the light microscope. Immunohistochemical analysis showed, compared with the control group, there were no significant differences in the expressions of glial fibril ary acidic protein, Bax, Bcl-2 and Caspase-3 proteins of nerve roots in the implantation group. The stimulation electrode of rabbit sacral nerve root is developed successful y, that is, the implantation is simple and safe as it can be used for long-term implantation without histopathological changes and apoptosis.
