Trehalose Is a nonreduclng dlsaccharlde of glucose that functions as a protectant In the stabilization of blologlcal structures and enhances stress tolerance to abiotic stresses in organisms. We report here the expression of a Grlfola frondosa trehalose synthase （TSase） gene for Improving drought tolerance In sugarcane （Saccharum offlclnarum L.）. The expression of the transgene was under the control of two tandem copies of the CaMV35S promoter and transferred Into sugarcane by Agrobacterium tumefaciens EHA105. The transgenlc plants accumulated high levels of trehalose, up to 8.805-12.863 mg/g fresh weight, whereas It was present at undetectable level in nontransgenlc plants. It has been reported that transgenlc plants transformed with Escherlchla coil TPS （trehalose-6-phosphatesynthase） and/or TPP （trehalose-6-phosphate phosphatase） are severely stunted and have root morphologlc alterations. Interestingly, our transgenlc sugarcane plants had no obvious morphological changes and no growth Inhibition in the field. Trehalose accumulation in 35S-35S：TSase plants resulted In In- creased drought tolerance, as shown by the drought and the drought physiological Indexes, such as the rate of bound water/free water, plasma membrane permeability, malondlaldehyde content, chlorophyll a and b contents, and activity of SOD and POD of the excised leaves. These results suggest that transgenlc plants transformed with the TSase gene can accumulate high levels of trehalose and have enhanced tolerance to drought.

Background： Osteoarthritis often affects the joint bilaterally, and the single-stage （SS） unicompartmental knee arthroplasty （UKA） is advantageous in terms of a single anesthesia administration, a short hospital stay, lower medical costs, and enhanced patient convenience. However, the complication risk of SS UKA continues to be debated. The aim of this article was to evaluate the clinical effectiveness, complications, and functional recovery of SS and two-stage （TS） UKA. Methods： From January 2008 to December 2013, we compared a series of 36 SS UKA with 45 TS UKA for osteoarthritis. The mean age was 65.4 years （range： 55-75 years）. The mean body mass index was 25.2 kg/m^2 （range： 22-29 kg/m^2）. The preand post-operative Oxford Knee Scores （OKSs）, complications, operative times, tourniquet times, the amount of drainage, and hemoglobin （Hb） were evaluated. The Chi-square test, Fisher＇s exact test, and paired and grouped t-tests were used in this study. Results： The mean tbllow-up was 50 months. No complications of death, fat embolism, deep vein thrombosis, and prosthetic infection were reported. Patients who underwent SS U KA had a shorter cumulative anesthesia time （ 113.5 vs. 133.0 rain, P 〈 0.01 ）. There were no significant variations between the values of the mean tourniquet time, the amount of drainage, pre- and post-operative Hb in the different groups. No patient required a blood transfusion. No statistical differences were found in the complications between two groups （P 〉 0.05）. At the final follow-up, the mean OKS improved from 39.48 ±5.69 to 18.83 ± 3.82 （P 〈 0.01 ）, with no statistical differences between the two groups （P 〉 0.05）. Patients who underwent SS UKA had a faster recovery. Conclusions： The single-staged UKA offers the benefits of a single anesthesia administration, redticed total anesthetic time, decreased overall rehabilitation time, and absence of an increase in perioperative mortality or complications compared with the TS bilateral UKA.
