Objective To determine the signal pathway of specifically expressed oncostatin M(OSM) in lens inducing retinal degeneration in transgenic mice. Methods A sequence-truncated OSM cDNA (661 bp) of mice was linked to ?A-crytallin promoter, and was micro-injected into unicellular embryo to set up the model of transgenic mice. Reversal transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA expression of gp130/OSMR? receptor in the retinae of OSM transgenic and non-transgenic mice. Rabbit anti-phosphorylated STAT-3 antibody was used to detect the protein expression of phosphorylated STAT-3,and mouse anti-cytochrome C antibody was used to detect the distributing of cytochrome C in retinae. Results Expression of gp130/OSMR? mRNA was found in retina of non-transgenic mice. At the 17.5th day in the embryonic stage, significant accumulation of the phosphorylated STAT-3 was detected in the retinal nucleolus in OSM transgenic retina. At the first day after birth, intensive staining of cytochrome C in OSM transgenic retina was found. Conclusions specifically expressed OSM in lens may act on gp130/OSMR? receptor in retinae, activate STAT-3, and cause the release of cytochrome C from mitochondria, which eventually induces widespread retinal degeneration.

Objective To determine the effects of lensspecific overexpression of OSM on the eye development. Methods A truncated mouse OSM cDNA (661 bp) was linked to the ?A-crystallin promoter. Transgenic mice were characterized by routine histological and immunohistochemical techiniques. TUNEL assays were used to detect cell death. The mRNA expression of caspase-3 was detected by in situ hybridization, Rabbit anti-cleavage caspase-3 antibody was used to detect active capase-3. Results At embryonic day (E) 14.5 and 17.5, expression of the OSM transgenic protein was detected specifically in lens fiber cells. The onset of retinal degeneration in the mid portion of the transgenic retinae was observed started from E17.5. By the time of birth 50% or more of the retinal cells were missing. The OSM transgenic retinal cells underwent apoptosis indicated by TUNEL assays. Most strikingly, activation of caspase-3 protein were observed throughout the transgenic retinas. Conclusions Lens-specific overexpression of OSM activate caspase-3, leading to abnormal eye development, apoptosis and widespread retinal degeneration.

Objective To explore the smoking cessation intervention impact on lung with genetic polymorphism of SOD3. The aim is to further reveal the importance of smoking cessation intervention on early COPD patients. Meth-ods 60 COPD patients with smoking cessation intervention and 40 COPD patients without intervention ( the control group) were enrolled in this study. Limosis peripheral blood was taken and whole blood corpuscle genomic DNA was extracted. The genetic polymorphism of SOD3 genes was determined by ligase detection reaction and polymerase chain reaction ( LDR-PCR) and serum SOD3 concentration was measured using ELISA. Lung function between the two groups before and after intervention were detected by microspirometry. Results ①The FEV1% and the FEV1/FVC% were increased after 3 and 6 months intervention in smoking cessation group(P<0.05). But there was no significant difference ( P <0.05 ) between 3 and 6 months. ② Different SOD3 genotypes have no significant on COPD pulmonary function after intervention(P>0.05). ③The serum of SOD3 concentration of COPD intervention group and the control have no significance after intervention ( P>0.05 ) . ④ The serum of SOD3 concentration a-bout CC and CG/GG genotype in COPD intervention group have no significance after 3 and 6 months intervention ( P>0.05 ) . Conclusion Smoking cessation interventions for patients with COPD pulmonary function improves significance in short-term. But different SOD3 genotypes have no effect on lung function after intervention. Smoking cessation intervention has no effect on in serum SOD3 concentration of COPD patients, and has no relationship be-tween the expression of SOD3 genetype.

To improve the solubility of quercetin ( QT) , one of flavonoids that can inhibit the proliferation of vari-ous types of cancer cells, the novel amphiphilic polymer N-( 4-methylimidazole)-hydroxyethyl-chitosan ( MHC) , synthetized by chemical derivatization from chitosan, was used as the self-assembly micelles of QT. The formed polymer was characterized by 1 H NMR, elemental analysis and pyrene fluorescence spectrometry. The formulation of MHC micelles loading quercetin was optimized through single factor experiment. Then the optimized formulation was obtained as follows:the concentration of MHC was 0. 67% and the ratio of drug and carrier was 1 ∶10. The micelles particle size was ( 99. 21 ± 1. 71) nm, Zeta potential was +( 20. 01 ± 0. 72) mV and drug loading was ( 5. 42 ± 0. 32 )%. The in vitro release curve was investigated and was found to conform to Higuchi equation of Q=0. 1101 t1/2 -0. 064. The results of in vivo experiment showed that the mean rentention time and bioavail-ability of the MHC-QT micelles were 21. 42 h and 57. 49 μg h/mL, respectively, compared to 0. 30 h and 2. 50 μg h/mL of the free QT solution. These indicated that the MHC micelles could significantly improve the solubility of QT, the drug sustained-release effect and bioavailability, which would used as carrier for the anti-tumor drugs.
