Objective To explore key points of nursing in treatment of tibial bone defect by united Ilizarov technology and bone transport. Methods A total of 12 patients treated tibial bone defect with combined Ilizarov technology and bone transport were retrospectively analyzed and summarized. Results All 12 patients were followed up for 5 to 24 months. Their average bone healing time was (9. 4 ± 2. 6) months, and average external fixation removal time was (10. 6 ± 2. 6) months. In one case, a little infection happened to the nail trail; after removal of crusts, the local part was cleaned with 75% alcohol cotton swab and kept dry, then the infection became better 2 days later. In another case, nonunion happened between the bone transport segment and the distal segment, so bone graft was done again. 2 cases of limb pain became better after delaying bone transport. No patients had complications due to nursing care. Conclusions Application of Ilizarov technique combined with bone transport on the treatment of tibial bone defect has advantages like small trauma, quick bone healing, equal length of lower limbs, and flexible knee joints. To guarantee operation effect and to improve patients′satisfaction, what is needed is postoperative observation and nursing of complications, psychological nursing, nursing in bone transport period, functional exercise and discharge guidance.

OBJECTIVE To clarify the weight index and optimize the technology of compound Mingmu Yijing pills. METHODS Water content, dissolution time limit and bolus-forming pass rate were included as evaluation indexes. The analytic hierarchy process(AHP) and the criterion importance through inter-criteria correlation(CRITIC) method based on the objectivity of indicators were adopted, AHP-CRITIC mixed weighting method. In this way, the relative coefficients of each index were calculated for weight distribution and comprehensive score, and the molding process was optimized and verified by Box-Behnken response surface test. RESULTS Compared with the single weighting method, the AHP-CRITIC mixed weighting method was more reasonable and stable. This method finally optimized the forming process conditions of Mingmu Yijing pills as follows: adding water amount of 0.8 times, the damp mass infiltration for 0.5 h, drying temperature of 60 ℃, drying time of 8 h. The mean comprehensive score of validation experiment was 88.21, RSD was 0.29%. CONCLUSION AHP-CRITIC method scientifically determines the weight of multiple indicators, and the verification test confirms that the optimized molding process is stable and feasible, which can be used in practical large-scale production.
