Microscopic authentication method of traditional Chinese medicine Gusuibu / 中国中药杂志

<p><b>OBJECTIVE</b>To provide practical method for microscopic authentication of traditional Chinese medicine Gusuibu and its adulterants.</p><p><b>METHOD</b>By means of light microscope, scanning electron microscopy and tissue section techniques, the morphology, the size of the rhizome scales and their bearing position in the original plants of Gusuibu and its adulterants, i. e. Drynaria roosii, D. delavayi, D. quercifolia and Pseudodrynaria coronans were analyzed.</p><p><b>RESULT</b>There were significant differences between scales length of D. roosii, D. delavayi and P. coronans, while there was no significant difference between that of D. roosii and D. quercifolia. The scale teeth of D. delavayi were usually curved, bifid and uneven distributed at the scale fringe, which was different from that of the other three species. The base of the scales sinks in epidermis in D. roosii, D. quercifolia, and P. coronans, while it bore at the raised part of epidermis in D. delavayi.</p><p><b>CONCLUSION</b>[corrected] Morphology, size and bearing position of the rhizome scales have significant differences in the several species. Therefore, these characteristics can be applied to the identification of Gusuibu and its adulterants.</p>

Technical assistance of living related renal transplantation in 68 cases / 中国组织工程研究

Sixty-eight cases undergoing living related renal transplantation in First Hospital of Sun Yat-sen University between April 2004 and August 2007 were selected.The informed consent was obtained from the donors and recipients.The clinical data about operation assistance were retrospectively analyzed,including the pre-operation air sterilization in operation room,preparation of apparatus,one-off utensils and medicine,donor position fixation,assistance in kidney perfusion and preparation,management and usage of medicines,and steps of assistance during operation by instrument nurse.The results show the operational apparatus and utensils were prepared well,and the nurses knew well operation process and worked in harmony with the surgeons.For the 68 donor kidneys,the warm ischemic time was 1-6 minutes,and cold ischemic time was 10-118 minutes.The operations for both donors and recipients ran smoothly and lasted for 2.5-4 hours.Blood loss was less than 200 mL.Vital signs were stable during operation,and no complications happened.Good pre-operative preparation,strict management of personnel participating in operation,and training of assistant techniques are the preconditions for operation assistance.Rigorous aseptic management and correct preservation of organs are the keys for assistance for living donor kidney transplantation.Short warm and cold ischemic time of the donor kidneys are of great importance for the success of operation and the long-term survival of transplanted patients.
