Retinoic acid (RA) receptor, is a group of ligand-regulated nuclear transcription factors and widely distributed in various tissue cells. The different subtypes of RA receptor can polymerize into homologous or heterogenous dimmers, and then participate in the physiological and pathological processes of embryonic development, cell proliferation and differentiation, and apoptosis. However, the relationship between the expression of RA receptor and the diseases is different in diverse cells or tissues. Recent researches demonstrated that RA receptor is closely related to the pathogenesis and development of renal diseases. This article aims to review the role of the RA receptor and its signal pathway in the development of renal diseases.

Objective To investigate the influence of family nursing intervention on daily life ability of senile dementia patients? Methods Eighty senile dementia patients were equally randomized into two groups: the control group and the observation group? The controls received conventional home nursing instruction and health education and those in the latter group were managed with home nursing intervention? The activity of daily living scale(ADL)was used to assess their daily life ability? Result After nursing intervention,the daily life ability of observation group was better than control group(Z = 18?914,P < 0?05)? Conclusions The family nursing intervention is effective in directing the dementia patients with exercises of daily living ability? Thus it may improve their ability in daily life?

Objective To investigate the effect of all-trans retinoic acid (ATRA) on transforming growth factor β1 (TGF-β1)/Notch signaling pathway in injured podocytes induced by adriamycin (ADR) in vitro.Methods Podocytes cultured in vitro were randomly divided into normal group,model group,ATRA treatment control group,12-hour ATRA intervention group and 24-hour ATRA intervention group.Morphological changes were observed by using light microscope.The expressions of TGF-β1,podocin,Notch 1,Jagged 1 mRNA were evaluated through real-time polymerase chain reaction (RT-PCR) and the corresponding proteins were detected by using Western blot.Results (1) No obvious changes between normal group and ATRA treatment control group were revealed as the plump podocytes and distinct outline were found in light microscope,while podocytes in model group showed disordered arrangement,fuzzy boundary,atrophy,hypertrophy and increased cellular debris.Of note,the podocytes in 12-hour ATRA intervention group and 24-hour ATRA intervention group almost returned to normal.(2) In contrast with those in model group,the amounts of TGF-β1,Notchl,Jaggedl mRNA levels decreased in 12-hour ATRA intervention group (1.34 ±0.43 vs.4.16 ±0.31,1.67 ±0.2 vs.4.21 ±0.92,2.08 ±0.27 vs.5.14 ±0.63,q =23.83,11.45,19.67,all P ＜0.05) and 24-hour ATRA intervention group (1.22 ± 0.16 vs.4.16 ± 0.31,1.73 ± 0.53 vs.4.21 ± 0.92,2.08 ± 0.29 vs.5.14 ± 0.63,q =24.85,11.18,19.67,all P ＜ 0.05),and the differences were significant;similar trend was detected in the protein levels (1.04 ± 0.03 vs.4.31 ± 0.10,1.06 ± 0.04 vs.4.47 ± 0.24,1.07 ± 0.04 vs.4.20 ± 0.16,1.06 ±0.03 vs.4.31 ±0.10,1.07 ±0.03 vs.4.47 ±0.24,1.09 ±0.03 vs.4.20 ±0.16,q =163.50,69.61,90.36,162.50,69.40,89.78,all P ＜ 0.05),and the differences were significant;whereas the level of podocin mRNA (1.13 ±0.05 vs.0.40 ± 0.06,1.16 ± 0.03 vs.0.40 ± 0.06,q =36.50,38.00,all P ＜ 0.05) and protein (1.01 ± 0.01 vs.0.44 ±0.01,1.02 ±0.01 vs.0.44 ±0.01,q =180.25,183.41,all P ＜0.05) increased,and the differences were sig nificant.(3) The expressions of Notch1,Jagged1 mRNA were positively correlated with TGF-β1 mRNA (r =0.84,1.00,all P ＜ 0.05),but negatively correlated with podocin mRNA (r =-0.95,-0.94,all P ＜ 0.05) in model group.Conclusions ATRA might alleviate podocyte injury through cutting the expressions of TGF-β1,Notch1,Jagged1 and raising the expression of podocin in injured podocytes induced by ADR.

Objective To evaluate the curative effect of urokinase combined with low molecular heparin sodium in managing arteriovenous fistula embolism. Methods Toally 48 patients with arteriovenous fistula embolism treated from January 2014 to October 2015 were selected for the study, where 22 were assigned into control group and 26 as trial group according to the registration time. The former group were treated with urokinase and the latter with urokinase combined with low molecular heparin sodium. The rate of recanalization, the rate of thrombosis recurrence, and the adverse reactions were compared between the two groups. Results The recanalization rate in the trial group was higher than that in the control group (P<0.05). The rate of thrombosis recurrence in the trial group was significantly lower than that the control group. There was no statistical difference in adverse reactions between the groups. Conclusion The thrombolytic effect of urokinase combined with low molecular heparin sodium is superior to that of urokinase alone, with a higher rate of recanalization.

BACKGROUND:Bone marrow mesenchymal stem cells(BM-MSCs)have been shown to possess the potential to differentiate into oocytes.However,immune rejection and a limited number of donors of BM-MSCs constrain the applications of BM-MSCs.Several studies have demonstrated that human umbilical cord matrix stem cells(UC-MSCs)also have an intrinsic ability to differentiate into oocyte-like cells in vitro.OBJECTIVE:To establish the method for UC-MSCs culture and to investigate the in vitro differentiation potential of UC-MSCs towards germ cells.METHODS:Umbilical cord from full-term normal deliveries was obtained in sterile condition.Collagenase I-digested cells were cultured in DMEM.The immunophenotype of cells was determined by flow cytometry.Lipoblasts,osteoblasts and chondroblasts were induced in different condition cultures.The expression of germ cells specific marker in UC-MSCs was determined by reverse transcdption-polymerase chain reaction.Follicular fluid was employed to induce UC-MSCs differentiation into germ cells.RESULTS AND CONCLUSION:Spindle-like umbilical cord cells were shown and cells in culture were extended to more than 10passages.BM-MSCs-like immunophenotypes were shown:CD29,CD44,CD73(SH3),CD90 and CD105(SH2)were positive;SSEA-4 was weakly positive;CD31,CD34,CD45 and HLA-DR were negative.After UC-MSCs were induced in different condition cultures,lipid droplet-,bone tubercle-,and cartilage tubercle-like structures emerged and the mRNA expressions of specific gene of fat,bone and cartilage were observed.Germ cells markers,OCT4,Stella,Ifitm3,were expressed in UC-MSCs.After induced by 5%,10% or 20% follicular fluid,cells aggregated and oocyte-like structures were observed.Human UC-MSCs could be cultured and amplificated in vitro.UC-MSCs showed immunophenotypes similar to BM-MSCs.UC-MSCs had the potential to differentiate into lipoblasts,osteoblasts,and chondroblasts.Oocyte-like structure was induced in vitro from UC-MSCs with germ cells specific marker.These findings suggest that UC-NSCs have the potential to differentiate into germ cells.

Isolated freshly rat islets were transferred to 24-well plates and incubated with different concentrations of glucose or resveratrol for 1 or 24 h.The results showed that resveratrol dose-dependently inhibited glucose-stimulated insulin secretion from isolated rat islets after 1 h incubation,with 10%,35%,and 80% (P<0.05 or P<0.01) decrease at the concentrations of 1,I0,and 100 μmol/L.10 μmol/L resveratrol decreased the intracellular calcium concentration by 60% (P<0.05).After incubation for 24 h,resveratrol increased palmitatesuppressed insulin secretion to 75% (P<0.01) of control.These results suggest that resveratrol acutely inhibits insulin secretion from primary pancreatic islet via regulating intracellular calcium ion concentration,and in the long run resveratrol may protect β-cells from lipotoxicity.

The effect of troglitazone on glucose-stimulated insulin secretion (GSIS) in pancreatic β-cells and its mechanism were investigated.10 μmol/L troglitazone had no effect on basal insulin secretion,but significantly decreased GSIS and stimulated AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) phosphorylations (all P<0.01).These reactions were completely reversed by AMPK inhibitor compound C,suggesting that the troglitazone acutely inhibits insulin secretion via stimulating AMPK activity in beta cells.
