OBJECTIVE: To evaluate the role of total glucosides of peony (TGP) as adjuvant therapy for prevention of cardiac allograft rejection in rats. METHODS: Rats with cardiac allograft were randomly divided into control group, tacrolimus-treated group, TGP-treated group and tacrolimus plus TGP-treated group. Graft survival time was observed. Allografts in some cases were examined by histological study seven days after transplantation. At the same time, the levels of CD4(+) and CD8(+) T cell subsets in peripheral blood were examined by using flow cytometry; the hepatic function and renal function of recipients were also tested. RESULTS: The graft survival time of the tacrolimus-treated group and tacrolimus plus TGP-treated group was (11.14+/-1.57) d and (13.57+/-1.99) d, respectively. The graft survival time of the tacrolimus plus TGP-treated group was longer than that of the tacrolimus-treated group (P<0.05). The histological study showed that the rejection of the tacrolimus plus TGP-treated group was slighter than that of the tacrolimus-treated group. The levels of CD4(+) T cell subset in the peripheral blood of the tacrolimus-treated and tacrolimus plus TGP-treated groups were (38.71+/-5.15)% and (32.43+/-4.39)% respectively 7 days after transplantation. The level of CD4(+) T cell subset in the tacrolimus plus TGP-treated group was lower than that in the tacrolimus-treated group (P<0.05). The level of CD8(+) T cell subset and the hepatic and renal function had no significant differences between the tacrolimus-treated group and the tacrolimus plus TGP-treated group. CONCLUSION: Effects of tacrolimus plus TGP in prevention of rejection are better than tacrolimus monotherapy in rats with cardiac allograft and without increasing side effects.

Objective To investigate the expression of glucose-regulated protein 78(GRP78)and cysteine aspartic acid protease 12(Caspase-12) and evaluate the endoplasmic reticulum stress (ERS) in rats with contrast-induced nephropathy (CIN),and observe the protective effects of hydroxytyrosol on CIN rats.Methods Eighty-four Wistar rats,(220±20) g,were randomly divided into control group,CIN group,hydroxytyrosol treated group (group C+H).At 12th,24th,48th,72th day after the rats model were established,BUN and Scr were detected.ELISA were used to detect the expression of methane dicarboxylic aldehyde (MDA),superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px).HE staining were used to evaluate the pathological change of kidney.TUNEL were used to detect the apoptosis of tubular ceils.Real-time PCR were used to detect the expression of GRP78 mRNA and Caspase-12 mRNA in tubular cells.Immunohistochemistry and Western blotting were used to detect the expression of GRP78 and Caspase-12 protein in tubular cells.Results BUN,Scr,the mRNA and protein expression of GRP78,Caspase-12 in hydroxytyrosol treated group were higher than that in control group(P ＜ 0.05),but were significantly lower than that in CIN group (P ＜ 0.05).Pathological changes and the apoptosis of tubular cells in CIN group were more serious than that in hydroxytyrosol treated group (P ＜ 0.05).Conclusions Endoplasmic reticulum stress may be associated with contrast-induced nephropathy.Hydroxytyrosol can protect kidney from contrast medium via reducing the endoplasmic reticulum stress.

0 05).Among them,WT but neither DN, Blank, nor Pio significantly ameliorated the increased concentrations of TGF-a1 and fibro nectin in culture medium induced by HG. Compared with DN and Blank, WT transfect ion significantly attenuated high glucose-caused elevation in c-fos, c-jun and p-ERK expression, reduction in Ⅰ-?B level, and incretio n in nucleus/cytosol ratio of NF-?B, while Pio demonstrated similarly signific ant changes only in p-ERK and NF-?B. No significant difference of GLUT-1 mRN A level was detected between HG groups. Conclusions Overexpressed PPAR?1 can su ppress increased ECM production from glomerular mesangial cells cultured in HG c ondition. Its inhibitory effects on activation of ERK/AP-1 and NF-?B pathways are involved. The further increase of PPAR?activity may have direct anti-fibr otic effect in diabetic kidney.

Objective To confirm the predictive value of diaphragm thickening fraction (DTF) on successful weaning by bedside ultrasound in patients with myasthenia gravis crisis. Methods A prospective study was conducted. The patients with myasthenia gravis crisis undergoing mechanical ventilation admitted to Department of Critical Care Medicine of the Affiliated Hospital of Qingdao University from March 2015 to February 2017 were enrolled. All patients underwent a low level pressure support mode of spontaneous breathing test (SBT), and rapid shallow breathing index (RSBI) was recorded. The indicators of right diaphragm thickness at the end of inspiration (DTei) and expiration (DTee) were determined by bedside ultrasound at 5 minutes and 60 minutes of SBT, and DTF was calculated, the changes in above parameters were observed during SBT. The patients were divided into successful weaning group and failure weaning group, and the differences in above indexes were compared between the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of DTF and RSBI at 60 minutes of SBT on successful weaning. Results A total of 37 patients were enrolled in the study. Ultrasonic measurement data of 63 person-times at 5 minutes of SBT and 50 at 60 minutes of SBT were obtained. There were no statistical differences in RSBI, DTei, DTee, and DTF at 5 minutes of SBT between successful weaning group (n = 33) and failure weaning group (n = 30). At 60 minutes of SBT, compared with successful weaning group (n = 33), the patients in failure weaning group (n = 17) had a higher RSBI (times·min-1·L-1: 80.41±29.08 vs. 63.94±23.84, t = 2.146, P = 0.037), and lower DTee, DTei and DTF [DTee (mm): 22.00±6.25 vs. 25.45±4.99, t = 2.127, P = 0.039; DTei (mm): 27.94±6.19 vs. 38.48±6.15,t = 5.731, P = 0.000; DTF: (24.46±14.11)% vs. (62.04±30.21)%, t = 4.845, P = 0.000]. There were no statistical differences in RSBI, DTei, DTee, and DTF between 5 minutes and 60 minutes of SBT in 33 person-time successful weaning (all P > 0.05). In 17 person who had 60 minutes of SBT but failed weaning, the RSBI at 60 minutes of SBT was significantly higher than that at 5 minutes (times·min-1·L-1: 80.41±29.08 vs. 57.29±22.46, t = 2.400, P = 0.029), and DTei and DTF were significantly decreased [DTei (mm): 27.94±6.19 vs. 35.35±6.84, t = 3.024, P = 0.000; DTF:(24.46±14.11)% vs. (61.89±23.97)%, t = 5.810, P = 0.000], but the change of DTee during SBT showed no statistical significance. ROC curve analysis showed that the area under ROC curve (AUC) of DTF at 60 minutes of SBT for predicting successful weaning was 0.898; when DTF ≥ 27.9% as the cut-off point, the sensitivity was 93.9%, specificity was 70.6%. The AUC of RSBI for predicting successful weaning was 0.669; when RSBI ≥ 86.50 times·min-1·L-1 as the cut-off point, the sensitivity was 81.8%, specificity was 52.9%. Conclusion DTF at 60 minutes of SBT is the effective index of successful weaning prediction in mechanical ventilation patients with myasthenia gravis crisis.
