Objective To investigate the effect of intermedin (IMD) on tubular cells apoptosis induced by renal ischemia/reperfusion (I/R) injury and its associated mechanism.Methods A total of twenty-four male Wistar rats were randomly divided into four groups (control group, I/R group, empty plasmid group and IMD group). One week after the removal of right kidney, ultrasound plasmid was used to transfect empty or IMD plasmid into the left kidney. Renal I/R model was made by clasping the left renal artery for 45 minutes. Tubular cell apoptosis was determined by TUNEL. Expression of Bax, Bcl-2, Fas was detected by semi-quantitative RT-PCR.Activity of caspase-8 and caspase-9 was evaluated with commercially available kits respectively.Protein level of caspase-3 was measured by Western blotting analysis. Results Compared with control group, apoptosis of tubular epithelial cells, expression of Bax and Fas, activities of caspase-8 and caspase-9, as well as protein level of caspase-3 were all significantly increased in I/R group (all P＜0.05). IMD pre-treatment significantly inhibited all these effects (all P＜0.05). There were no differences of above parameters between empty plasmid group and I/R group. Conclusion IMD pre-treatment protects against renal I/R injury by inhibion of tubular epithelial cell apoptosis.

As one of the major geriatric syndromes,frailty exerts adverse effects on life expectancy and quality of life of the elderly.Because of its importance,a number of methods and tools have been introduced for the assessment of frailty.Malnutrition,as an independent risk factor,interacts with frailty and is involved in its progression.This article reviews recent studies on frailty and malnutrition.

[Objective] To search a suitable preoperative intestinal cleansing method for the operation of colon and rectum. [Methods] A randomized controlled trial was applied in 70 cases before colic and rectal operations. Group A was give:n decoction of Folium Cassiae for oral use and saline enema and Group B was treated with saline enema only. The effect on intestinal cleansing was observed during the operation. [Results] In Group A, 26 cases were remarkably effective in intestinal cleansing, 8 effective, and 1 ineffective and 14, 16 and 5 in Group B respectively ( P

Objective To make sure the psychological condition of patients with liver transplantation,and then make out certain effective nursing methods. Methods Investigated 94 patients with liver transplantation by MSSNS,analyzed the datum. Results The average score of the patients with liver transplantation was higher than the in-patients expected those in the department of psychology,P

Objective To examine among preschool children the validity, reliability and sensitivity of a new assessment tool of Mandarin sentence recognition in babble noise, consisting of twenty-seven equivalent lists, as well as to investigate the effect of age and gender on children's speech recognition. Methods Fifty-four normalhearing children aged 4 to 6 years were recruited from Beijing and were divided into three age groups (4～, 4.5～,and 5.0～6.0 years) containing 18 children each, half boys and half girls. According to randomized split-plot design, we examined their speech recognition ability with 27 sentence-in-babble-noise lists in a sound-treated booth in a kindergarten (ambient noise ＜40 dB). The sentences were presented at fixed intensity of 65 dB SPL, paired with competing babble noise at three different signal to noise ratios (SNR= +1, -2, -5 dB) by the same loudspeaker with 0° azimuth. Speech recognition score were calculated based on the children's repetition of keySNR functions exhibited that the threshold was -1.96±0. 19 dB SNR and the slope was 15.8%±1.1%/dB for of variance and Post- Hoc Scheffe test indicated that significant differences in performance were most pronounced between the 4～ year group and the other two groups (P＜0.001), while there was no significant difference between 4.5～ year group and 5.0～6. 0 year group (P=0. 90). The girls' performance was also significantly better than boys' (P＜0. 001). Conclusion The 27 lists of Mandarin speech recognition in babble noise were equivalent among children, and the sensitivity of performance versus SNR was 15.8%/dB. Both of them were below the adult averchildren aged 4.5～ up years. Even though the performance differed between boys and girls, the difference was relatively small compared to 24.6%, the critical difference as the reliability indicator.
