BACKGROUND:Retinoid X receptor (RXR) plays a central role in the regulation of intracellular receptor signaling pathways. The activation of RXR has protective effect on H2O2-induced apoptosis of H9c2 ventricular cells in rats. But the protective effect and mechanism of activating RXR in cardiomyocytes against hypoxia/reoxygenation (H/R)-induced oxidative iniury are stillunclear. METHODS:The model of H/R injury was established through hypoxia for 2 hours and reoxygenation for 4 hours in H9c2 cardiomyocytes of rats. 9-cis-retinoic acid (9-cis RA) was obtained as an RXR agonist, and HX531 as an RXR antagonist. Cultured cardiomyocytes were randomly divided into four groups:sham group, H/R group, H/R+9-cis RA -pretreated group (100 nmol/L 9-cis RA), and H/R+9-cis RA+HX531-pretreated group (2.5 μmol/L HX531). The cellviability was measured by MTT, apoptosis rate of cardiomyocytes by flow cytometry analysis, and mitochondrial membrane potential (ΔΨm) by JC-1 fluorescent probe, and protein expressions of Bcl-2, Bax and cleaved caspase-9 with Western blotting. Allmeasurement data were expressed as mean±standard deviation, and analyzed using one-way ANOVA and the Dunnett test. Differences were considered significant whenP was <0.05. RESULTS:Pretreatment with RXR agonist enhanced cellviability, reduced apoptosis ratio, and stabled ΔΨm. Dot blotting experiments showed that under H/R stress conditions, Bcl-2 protein level decreased, while Bax and cleaved caspase-9 were increased. 9-cis RA administration before H/R stress prevented these effects, but the protective effects of activating RXR on cardiomyocytes against H/R induced oxidative injury were abolished when pretreated with RXR pan-antagonist HX531. CONCLUSION:The activation of RXR has protective effects against H/R injury in H9c2 cardiomyocytes of rats through attenuating signaling pathway of mitochondria apoptosis.

AIM:To investigate the effects of 1.8mm coaxial micro incision phacoemulsification on corneal endothelial injury and postoperative visual acuity.METHODS: Totally 145 eyes in 120 patients underwent phacoemulsification from July 2013 to July 2015 were randomly divided into observation group 60 cases (73 eyes) and control group 60 cases (72 eyes).The observation group 60 cases were given 1.8mm coaxial micro incision cataract phacoemulsification operation,while the control group were given traditional 3.2mm coaxial micro incision cataract surgery.The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),corneal thickness of incision area,incision width,incision length,macular retinal thickness,surgically induced astigmatism,corneal endothelial cell counts and complications of the two groups were compared.RESULTS: The UCVA and BCVA on 1wk after surgery of the observation group were significantly higher than the control group (t=3.604,7.109;P<0.05);the width of incision on 1wk and 1mo after surgery of the observation group were significantly less than the control group (t=205.3,225.2;P<0.05).The length of incision in observation group was significantly greater than the control group (t=3.926,5.009;P<0.05).Macular retinal thickness 1wk after surgery of the observation group was significantly less than the control group (t=2.817,P<0.05).The surgically induced astigmatism was significantly less than the control group (t=19.43,22.16;P<0.01);the difference of corneal edema between the two groups was not significant (8.22% vs 11.11%) (x2=0.348,P>0.05).CONCLUSION: The 1.8mm micro incision phacoemulsification is helpful to improve the visual acuity of patients with cataract phacoemulsification,which may be related to the reduction of corneal cell injury,enhancement of corneal closure and decrease post-operation corneal original astigmatism.

AIMTo study the vasodilation effect of atropine and its mechanism.

METHODSIsometric tension was recorded in isolated rat super mesenteric arteries precontracted by noradrenaline (NE) to study the vasodilation effect of atropine, and to investigate the role of endothelial cell and vascular smooth muscle cell on vasodilation.

RESULTSAtropine was shown to significantly dilate the endothelium-intact and endothelium-denuded arteries precontracted by NE. Nomega-Nitro-L-arginine methyl ester (L-NAME, nitric oxide synthase inhabitor), indomethacin (cyclooxygenase inhibitor), propranolol (general beta adrenoceptor antagonist) and glibenclamide (ATP sensitive potassium channel inhibitor) showed no effect on vasodilation of atropine. Atropine did not affect the concentration-contraction curve of K+. However, atropine suppressed the contraction induced by NE and CaCl2, but not that by caffeine in the Ca+ -free Krebs solution.

CONCLUSIONAtropine showed significant vasodilation effect which may derive, in part, from endothelium. Besides, atropine could inhibit the receptor-mediated Ca2+ -influx and Ca2+ -release, which was inferred to the mechanism of atropine on vasodilation.

OBJECTIVETo investigate regulation function of anodonta glucan HBP-A on chondrocytes through Wnt pathway in vitro.

METHODSRat chondrocytes were cultured and differentiated induced with IL-1beta (10 ng/ml) in vitro. Chondrocytes were divided into five groups:IL-13 group,IL-1beta + IWP-2 (5 microM,Wnt pathway inhibitor) group, IL-1beta + HBP-A (0.3 mg/ml) group and IL-1beta + IWP-2 + HBP-A group. Wnt-3a, beta-catenin (24 h,48 h,72 h) and MMP-13(72 h) genes expression were detected by Rt-PCR, while beta-catenin, MMP-13, Sox-9 and coll-II (48 h) protein expression were measured by Western-blot.

RESULTSAfter induction of IL-1beta, gene expression of Wnt-3a, beta-catenin and MMP-13 were increased,so were the protein expression of beta-catenin and MMP-13. In contrast,protein expression of Sox-9 and Coll-II were declined. Following addition of HBP-A, Wnt-3a, beta-catenin and MMP-13 were shown as induction of IL-1beta, but protein expression of Sox-9 and Coll-II were upgraded. Combining HBP-A with IWP-2 led to the lowest level in Wnt-3a, beta-catenin gene and beta-catenin protein expression and highest expression of Sox-9 protein.

CONCLUSIONHBP-A could not only delay the differentiation of chondrocytes through downgrading the signal expression of Wnt/beta-catenin,but also adjust the expression of Wnt-3a, beta-catenin and Sox-9 when combinated with the Wnt inhibitor.
