Objective To report the clinical effect,characteristic and functional recovery of replantation of amputated pediphalanx. Methods Sixty cases (70 toes) of amputated toes had been taken the replantation which methods were anterograde and changing postural. Results Sixty-eight were successful in all the 70 amputated toes.The survival rate was 97%.The shape of replanted toes was good.About the range of flexion,the great toes were 25?～60? and the second and third toes were 36?～85?.The two-point discrimination on the toe tip was 1.1～1.8 mm.In the gait 60 cases had been normal and 10 cases had closed to normal. Conclusion The replantation of amputated toe must be performed with taking great pains.The successful operation can reduce the degree of disability of patient and remain the function and shape of the foot.To raise the rate of success of the operation,the skilled technology of microsurgery was the most important.

ObjectiveTo investigate the effects of inoculation of potassium-solubilizing bacteria on the physiological characteristics of Paris polyphylla var. yunnanensis. MethodThe effects of different potassium-solubilizing bacteria on leaf area，photosynthetic pigment content， and active component indexes of P. polyphylla var. yunnanensis were investigated by pot planting at room temperature. ResultThe results showed that the inoculation of potassium-solubilizing bacteria could increase the leaf area of P. polyphylla var. yunnanensis. The largest average leaf area was observed in the S3 group，reaching 10.497 cm²，with a maximum increase of 11.0% compared with that of the CK group. The inoculation of potassium-solubilizing bacteria could increase the content of photosynthetic pigments in leaves. Among them，the increase in chlorophyll a content was significant （P<0.05），which was 80.6% higher than that of the CK group. The chlorophyll a/b values in all treatment groups were higher than that of the CK group. The activities of superoxide dismutase（SOD），catalase（CAT） and peroxidase（POD） in the leaves of P. polyphylla var. yunnanensis increased by 88.4%，33.8%， and 30.6%，respectively， as compared with that in the CK group. The inoculation of potassium-solubilizing bacteria could promote the accumulation of osmoregulation substances such as soluble sugar and soluble protein in leaf cells of P. polyphylla var. yunnanensis，with a maximum increase of 55.3% and 70.5% respectively compared with that of the CK group. Meanwhile，it also reduced the content of malondialdehyde（MDA），with a maximum decrease of 34.1% compared with that of the CK group. The results of correlation analysis showed that there were some correlations between different chemical components in P. polyphylla var. yunnanensis leaves. ConclusionThe inoculation of potassium-solubilizing bacteria can effectively promote the growth and development of P. polyphylla var. yunnanensis and improve its survival ability in adversity. It is of practical scientific significance and potential application value for improving the survival rate of P. polyphylla var. yunnanensis by artificial planting.
