Objective To investigate the effect of dexmedetomidine on postoperative renal function of patients with rheumatic heart disease following valvular heart surgery. Methods Fifty patients following valvular heart surgery were randomized into experimental group and control group,with 25 cases in each group. The patients in experimental group receiveddexmedetomidine 0.5 μg/kg infusion 15min before induction, and then 0.5 μg/(kg·h) infused to the end of surgery, while those in control group received the same amount of saline in the same way. Blood from central venous was collected before surgery, at the end of surgery, 24 h and 48 h after surgery in order to detect Src, BUN and Cys C and the length of ICU duration was also recorded. Results Src and Cys C of the patients in both groups obviously elevated 24h after surgery when compared with pre-operation , while BUN elevated at both 24 h and 48 h after surgery(P < 0.05). Compared with those in control group, Src, BUN and Cys C were lower in experimental group ( P < 0 . 05 ) , and the length of ICU duration was shorter (P < 0.05). Conclusion Dexmedetomidine could improve the postoperative renal function after valvular heart surgery and lead to a better prognosis.

Objective:To investigate the role and action mechanism of aquaporin 3 (AQP3) in skin photoaging.Methods:Normal human skin fibroblasts (NHDF) were divided into several groups: NHDF group receiving normal culture without transfection, AQP3 cDNA group transfected with AQP3 cDNA, AQP3 siRNA group transfected with AQP3 siRNA, heterogeneous nuclear ribonucleoprotein Q (hnRNPQ) cDNA group transfected with hnRNPQ cDNA, hnRNPQ siRNA group transfected with hnRNPQ siRNA, AQP3-hnRNPQ cDNA group transfected with AQP3 and hnRNPQ cDNAs, AQP3-hnRNPQ siRNA group transfected with AQP3 and hRNPQ siRNAs, cDNA empty vector group transfected with a cDNA empty vector, and siRNA empty vector group transfected with a siRNA empty vector. Transfected or untransfected NHDFs were irradiated with ultraviolet A (UVA) at a dose of 10 J·cm -2·d -1 for 3 consecutive days to establish a model of cellular senescence, and NHDF receiving no UVA irradiation served as a control. A cell counting method was used to evaluate the cellular proliferative activity, a senescence-related β-galactosidase staining kit to evaluate the senescence level of NHDFs in each experimental group, and luciferase reporter gene technology to assess the transcriptional regulation activity of p53. Western blot analysis was performed to determine the expression of AQP3, hnRNPQ and senescence-related proteins p53 and p21 in NHDFs. Two-independent-sample t test was used for comparisons between two groups, and one-way analysis of variance for comparisons among multiple groups. Results:After 3-day consecutive irradiation with UVA, the expression of p53 and p21 in NHDFs and the percentage of β-galactosidase-positive cells significantly increased compared with the unirradiated control group (all P < 0.05) , but the expression of AQP3 and cellular proliferative activity on days 5, 6 and 7 significantly decreased in the UVA group compared with the unirradiated control group (all P < 0.05) . After 3-day consecutive irradiation with UVA, aggravated senescence-related phenotypes of UVA-induced NHDFs were observed in the AQP3 siRNA group compared with the siRNA empty vector group, and there were significant differences in the expression of p53, p21 and hnRNPQ, percentage of β-galactosidase-positive cells, p53 transcriptional regulation activity and cellular proliferative activity between the 2 groups (all P < 0.05) . Further silencing of the hnRNPQ gene could reverse the above effects. Compared with the siRNA empty vector group, the senescence-related phenotypes of UVA-induced NHDFs were attenuated in the hnRNPQ siRNA group, and significant differences were observed between the 2 groups in terms of the expression of p53, p21 and hnRNPQ, percentage of β-galactosidase-positive cells, p53 transcriptional regulation activity and cellular proliferative activity (all P < 0.05) . After 3-day consecutive irradiation with UVA, the senescence-related phenotypes of UVA-induced NHDFs were significantly attenuated in the AQP3 cDNA group compared with the cDNA empty vector group (all P < 0.05) , manifesting as significantly decreased expression of p53 (0.25 ± 0.06 vs. 0.56 ± 0.08) , p21 (0.23 ± 0.06 vs. 0.70 ± 0.07) and hnRNPQ (0.82 ± 0.09 vs. 0.92 ± 0.03) , percentage of β-galactosidase-positive cells (31.23% ± 6.54% vs. 81.53% ± 7.62%) and p53 transcriptional regulation activity (2.52 ± 0.36 vs. 7.16 ± 0.25) , but increased cellular proliferative activity ([2.93 ± 0.33]× 10 6/ml vs.[2.15 ± 0.23]× 10 6/ml) , and further overexpression of hnRNPQ could reverse the above effects. After 3-day consecutive irradiation with UVA, the expression of p53, p21, percentage of β-galactosidase-positive cells, p53 transcriptional regulation activity and cellular proliferative activity in the hnRNPQ cDNA group were 1.41 ± 0.09, 1.42 ± 0.06, 91.06% ± 4.24%, 12.35 ± 0.88 and (1.23 ± 0.41) × 10 6/ml respectively, and the senescence-related phenotypes of UVA-induced NHDFs were significantly aggravated in the hnRNPQ cDNA group compared with the cDNA empty vector group (all P < 0.05) . Conclusion:AQP3 may alleviate the UVA-induced senescence of NHDFs by regulating hnRNPQ and downregulating p53 expression.

Objective To investigate relationships between serum levels of anti?tyrosinase IgG antibody(TYR IgG)as well as anti?tyrosinase?related protein?1 IgG antibody(TRP?1 IgG)and vitiligo. Methods Enzyme linked immunosorbent assay(ELISA)was performed to detect serum levels of TYR IgG and TRP?1 IgG in 260 patients with vitiligo and 50 health controls. The threshold for defining a positive test result was set at 3 standard deviations above the mean serum level of TYR IgG or TRP?1 IgG in the healthy controls. Results The positive rate of TYR IgG and/or TRP?1 IgG in the vitiligo group was 57.31%(149/260). The positive rates of TYR IgG and TRP?1 IgG were both significantly higher in the vitiligo group than in the control group(TYR IgG:37.3%[97/260]vs. 0,χ2=25.441, P<0.01;TRP?1 IgG:33.5%[87/260]vs. 0,χ2=21.630, P<0.01). The positive rate of TYR IgG was not associated with that of TRP?1 IgG in the vitiligo group(r=-0.032, P>0.05). Among patients with vitiligo, the positive rate of TRP?1 IgG was significantly higher in females than in males(χ2=5.811, P<0.05), as well as in patients aged≤20 years than in those aged>20 years(χ2=6.498, P<0.05), while the positive rate of TYR IgG didn′t differ between females and males, or between patients aged ≤ 20 years and those aged > 20 years (both P >0.05). Conclusion Detection of TYR IgG and TRP?1 IgG may provide some evidence for the diagnosis and treatment of vitiligo.
