Objective To evaluate the effect of transitional care on the quality of life in patients with maintenance hemodialysis (MHD).Methods 101 MHD patients with symptoms of kidney ＜ 80 points were assigned into the interventional group (47 of 51 cases completed the study) and the control group (45 of 50 cases completed the study) by random number table method.The patients in the interventional group received transitional care for 6 months,while control group received routine care.The effects on function index,satisfaction index and clinical index were evaluated at the 3rd month and 6th month after intervention.Results 6 months after intervention,the scores of physical composite,mental composite,burden of kidney disease,symptoms/problems list,effects of kidney disease in the interventional group were 51.78±5.91,55.32±5.36,29.79±17.64,79.39±6.73,68.02±11.38,while the scores of the control group were 38.22±9.46,42.03±8.32,19.58±17.25,69.49±10.10,52.09±16.78,and the difference between the two groups was statistically significant (t=5.308-9.063,Z=-3.07,P ＜ 0.01).The scores of self-management behavior,health locus of control in the interventional group were 71.30-±5.42,25.74±2.42,while the scores of the control group were 65.0±8.74,22.47±3.97 (t=4.132,4.759,P ＜ 0.01).The nursing satisfaction in the interventional group scored 91.06±7.29,which was significantly higher than the control group scored 86.22±10.72 (Z=-2.45,P＜ 0.05).The level of serum phosphorus (PO4),Ca × PO4 products,parathormone (PTH) in the interventional group were (1.76±0.35) mmol/L,(51.02±10.04) mg2/dl2,464.56 ng/L,which were significanlty lower than (2.01±0.54) mmol/L,(57.41±17.38) mg2/dl2,625.78 ng/L in the control group (t=-2.691,-2.167,-2.000 in tum,P ＜ 0.01 or 0.05).Conclusions Transitional care achieves good effectiveness on the quality of life in patients with MHD.

OBJECTIVE To compare the difference of octave band CE-Chirp ABR response threshold and behavioral auditory thresholds in children with hearing loss, and to explore the clinical value of octave band CE-Chirp ABR. METHODS Twenty-one children (40 ears) with hearing loss were selected. The octave band CE-Chirp ABR response threshold and behavioral auditory hearing threshold were measured in quiet environment. The results of two different test methods were compared. RESULTS The frequencies of octave band CE-Chirp ABR response thresholds and behavioral auditory thresholds were statistically analyzed. The correlation coefficients at different frequencies were 0.693, 0.830, 0.836 and 0.845, respectively, and the P values were ＜0.05. CONCLUSION There is good correlation between octave band CE-Chirp ABR response and behavioral auditory hearing measurement. Octave band CE-Chirp ABR, as an objective audiometry technique, has good stability and reliability for the objective response of hearing loss, and can better reflect the hearing level.

Objective:To investigate the effect of intercellular adhesion molecule-1 (ICAM1) targeted miR-133a-5p on lipopolysaccharide (LPS)-induced alveolar epithelial A549 cell injury.Methods:Dual lucife-rase reporter assay was used to verify the ICAM1 targeted effect of miR-133a-5p.A549 cells were induced by LPS in vitro and divided into the control group, LPS group, LPS+ negative control(miR-NC) group, LPS+ miR-133a-5p group, LPS+ small interfering RNA(si)-NC group, and LPS+ si-ICAM1 group.The expression levels of miR-133a-5p and ICAM1 mRNA were detected by real-time fluorescent quantitative PCR.Apoptosis was detected by flow cytometry.The expression levels of ICAM1, Bcl-2, Bax and cleaved caspase-3 protein that could activate cysteine were detected by Western blot.The expression levels of interleukin-6 (IL-6) and tumor necrosis factor α(TNF-α) were detected by enzyme linked immunosorbent assay kit. Results:Compared with the control group, the LPS group had a decreased expression level of miR-133a-5p (0.39±0.04 vs.1.00±0.09) in A549 cells, increased expression of ICAM1 (0.86±0.08 vs.0.39±0.03), an increased apoptotic rate [(27.65±2.47)% vs.(8.13±0.89)%], and increased secretion of IL-6 [(624.59 ± 51.42) ng/L vs.(194.25±18.43) ng/L] and TNF-α [(548.35±51.42) ng/L vs.(174.26±19.43) ng/L]. The differences were significant (all P<0.05). Compared with the LPS+ miR-NC group, the apoptosis rate of A549 cells [(13.46±1.38)% vs.(28.71±2.54)%] in LPS+ miR-133a-5p group were significantly decreased, and the secretion of IL-6 [(296.43±23.51) ng/L vs.(635.86±55.41) ng/L] and TNF-α [(321.14±30.56) ng/L vs.(563.24±49.52) ng/L] was significantly decreased (all P<0.05). Compared with LPS+ si-NC group, the apoptosis rate of A549 cells [(13.65±1.64)% vs.(23.51±2.33)%] in LPS+ si-ICAM1 group was significantly decreased, and the secretion of IL-6 [(324.15±29.41) ng/L vs.(625.39±52.59) ng/L] and TNF-α [(334.65±20.46) ng/L vs.(534.97±51.42) ng/L] were significantly decreased (all P<0.05). Conclusions:miR-133a-5p can alleviate LPS-induced alveolar epithelial cell injury, and the mechanism may be related to down-regulation of ICAM1 expression.
