BACKGROUND:It is an important and complex issue for the incidence of bacterial infection and complications after transplantation. The monitoring and care after transplantation can improve the success rate of transplantation. OBJECTIVE:To search the database of China National Knowledge Infrastructure, North American Clinical Trial Register and Thomson Reuters Web of Science database, and to perform literature metrological analysis and clinical trials registration project analysis on the published literatures of the monitoring and care after transplantation. METHODS:A total of 138 literatures were searched with the key words of“intensive care, transplantation”in the database of China National Knowledge Infrastructure on the intensive care after transplantation. 23 literatures were used for further analysis by reading titles and abstracts and 115 papers were excluded; the Thomson Reuters Web of Science database was searched with the key words of“intensive care, transplantation”for the literatures on the intensive care after transplantation published from 2008 to 2013;the North American Clinical Trial Register was searched with the key words of“intensive care, transplantation”for the related clinical trials, and a total of 50 registered projects were obtained, only 10 interventional studies. RESUTLS AND CONCLUSION:In recent years, the literatures on the intensive care after transplantation show a gradual increase trend. Compared with international research, fewer researches in this field emerge in China, literature quantity and quality need to be improved. There have been 1 693 papers published in the Thomson Reuters Web of Science database regarding the intensive care after transplantation. United States published the most literatures than other countries, total 532 papers, accounting for the largest proportion, 31.424%of total literatures. Transplantation Proceeding published the most literatures, total 144 papers, accounting for 8.506%of total literatures. There are 50 clinical trial registration projects related to the intensive care after transplantation in the North American Clinical Trial Register, 10 of them were interventional study, accounting for the majority, fol owed by observational study. Diagnostic study had no related registration projects. The surgery of transplantation was complex with trauma. The early monitoring and care post-transplantation are directly related to the success of surgery. Strengthening the monitoring and care of patients’ vital signs, rejection, bacterial infections and other aspects can reduce the complications and improve patients survival rate and quality of life.

Objective To evaluate the performances of glucose oxidase immobilized on hydrophilic-hydrophobic silica gel, which may be employed to prepare glucose sensor for the determination of glucose in body fluids. Methods The silica gel was prepared from precursors ?-aminopropyltrimethoxysilane (APTMOS) and methyltrimethoxysilane (MTMOS) by sol-gel technique. Glucose oxidase (GOD) was covalently attached to the silica gel via carbodiimide coupling reaction between a carboxylic acid group on enzyme and an amine group of the silica gel under the participation of the linking reagents 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride and N-hydroxysuccinimide. The performances of immobilized GOD were explored. Results The optimum conditions were obtained as follows: volume fraction of APTMOS 70%, enzyme content given 16 800 U, the temperature of 35 ℃ and buffer pH 5.5. The decrement in the activity of immobilized GOD for the first 2 weeks was less than 10% of its original activity, and the activity of immobilized GOD retained more than 75% of its original activity after 1 month of testing. Six independently prepared immobilized GOD on the silica gel resulted in an average bioactivity of 1 290.9 ?mol?min -1?g -1 with an R.S.D. of 3.4%. The Michaelis constant (K m) of immobilized GOD was 9.1 mmol?L -1. Conclusion Immobilizing GOD on the silica gel via the formation of peptide bonds is an outstanding enzyme immobilization method.
