Background Retinal neovascularization varies with the change of microRNA (miRNA) expression level.Quantitative real-time PCR (qRT-PCR) is a common method for the analysis of miRNA expression profiling.However,the housekeeping genes selected as references may exhibit differential expression levels under the distinctive experimental conditions.The accuracy of the levels of target gene expression often is affected if the selected housekeeping genes with significantly fluctuating expression as references.Determining a reference gene with stable expression level is the premise to consecutive studies.Objective This study was to compare the expression levels and stability of the frequently used reference genes for miRNA expression analysis in normally developing eyes and in eyes of a mouse model of oxygen-induced retinopathy (OIR),and select the optimal reference gene (s) exhibiting stable ocular expression under both hypoxia and normal development conditions.Methods P7,P12,P17,P37 and 8-week-old clean C57BL/6J mice were selected randomly.q-PCR was used to detect the dynamic changes of relative expressions of 5 kinds of reference genes in different ages of mice,including snRNAU6 (RNU6),5S ribosomal RNA (5s rRNA),snoRNA U68 (U68),snoRNA U70 (U70),snoRNA U49A (U49A).Other 40 P7 mice were randomized into the normal control group and the OIR group.The mice of the normal control group were fed in the normal oxygen environment,and those in the OIR group were raised in the (75-±2)％ oxygen environment for 10 days.Fluorescine was injected via ritrobulbar vein for retinal stretched preparation,and the histopathological examination of mouse retinas was performed to identified the models.The expressing difference of 5 kinds of reference genes in the retinas were detected to compare the differences of 5 kinds of genes expression between the two groups.GeNorm program was employed to compare the stability of the expressing genes.This study were approved and granted by Ethical Committee of Tianjin Medical University and met the requirements stipulated in the Association for Research in Vision and Ophthalmology Statement for the Use of Animals in Ophthalmic and Vision Research.Results Across the developmental ages,the expression levels of U68 in the eye exhibited the greatest variability,and then coming with U49A,U70,RNU6 and 5s rRNA.Significant differences were seen across the developmental ages for the expression levels of U68,U49A,U70,and RNU6 (U70:F =7.005,P =0.000 ; U68:F =10.189,P =0.000 ; U49A:F =21.134,P=0.000;RNU6:F=4.968,P=0.004).Expression of 5s rRNA showed the least variability across the developmental ages (F=2.099,P =0.107).In P17 mice of the OIR group,tortuous access vessels and non-perfusion area were found in the retinal section.Hematoxylin-eosin stain showed the neovascular sprout through across the inner limiting membrane.The relative expression of U70 exhibited the greatest variability and then were U49A,U68 and 5s rRNA in turn in P17 OIR mice,and significantly elevated expressions were found in U70,U49A,U68 and 5s rRNA genes between the OIR group and the normal control group (t =5.174,P =0.000;t =3.376,P =0.012;t =4.802,P =0.000 ;t=2.856,P=0.029).Expression of RNU6 showed the least variability between the two groups (t =2.104,P=0.065).As analyzed by GeNorm program,the stability for the five reference genes across developmental ages was 5s rRNA/RNU6＞ U70 ＞ U49A ＞ U68,and the optimal reference combination was 5s rRNA and RNU6.Whereas the stability for the OIR model was 5s rRNA/RNU6＞U68＞ U49A＞U70,and the optimal reference combination was 5s rRNA and RNU6.Conclusions Reference genes should be selected based on specific subjects and experimental conditions when qRT-PCR is used to analyze miRNA expression levels.In the OIR model,both developmental and hypoxic factors need to be considered.5s rRNA and RNU6 reference combination is the preferred option for the qRT-PCR analysis of ocular miRNA expression if available.

Objective To establish a gene diagnosis assay for spinal muscular atrophy(SMA) in children. Method Analysis of the survival motor neuron (SMN) gene in 19 SMA patients and in 21 normal controls were performed by using polymerase chain reaction - fragment length polymorphism (PCR - RFLP) method. Result Deletion of exon 7and 8 in SMNt gene were found in all 19 SMA patients, while no such changes were found in normal controls. Conclusion The SMNt gene exon 7 and 8 examine can be applied to SMA gene diagnosis, and the PCR- RFLP method have higher sensitivity and particularity to the SMA diagnosis.

Myocardial ischemia-reperfusion injury (MI/RI) is an inflammatory cascade process involving the interaction of multiple factors.In recent years,more and more evidence suggests that NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome,an important component of the innate immune system,is closely associated with the inflammatory damage of MI/RI.Furthermore,blockage of NLRP3 inflammasome or the release of its downstream pro-inflammatory cytokines may provide new therapeutic targets for this disorder.

Objective To evaluate the effect of behavioral intervention on changing knowledge, attitude and practice (KAP) about AIDS among the migrant workers in railway construction sites. Methods Health education and behavioral intervention on AIDS were carried out among the migrant workers for 4 to 5 months, who were clusteredly sampled from two railway construction sites, in the forms of mini-media, peer education and so on. Questionnaire survey was conducted among them before and after the intervention. Results The results showed that the knowledge awareness of the migrant workers on the transmission routes, preventions of AIDS and self-protection consciousness increased significantly by comparing the indexes of 943 pre-intervention with those of 671 post-intervention workers. After intervention procedures, the rate of those workers who would adopt negative attitudes towards the HIV infected persons because of fear and discrimination was decreased from 9.8% and 10.5% to 6.3% and 3.5% (both P

OBJECTIVE: To study the bioaccessibility and evaluate the safety of inorganic elements in decoction of "Zhebawei" traditional Chinese medicines (TCMs). METHODSE: The bioaccessibility of inorganic elements in decoction of "Zhebawei" TCMs was measured based on in vitro digestion and inductively coupled plasma atomic emission spectrometer (ICP-AES) and the safety of these elements were evaluated by comparing with the safe limits issued by the FAO and WHO. RESULTS: The bioaccessibility of the inorganic elements was less than 1, and varied among different elements of the same herbal medicine or for the same element among different herbal medicines. Cd, V, Se, Cr, Sn, and As were not detected in the dialysate of some TCMs' decoction after in vitro digestion because of the total content being low or undetected in decoction. The result of safety evaluation showed that the daily intakes of Ni, Fe, Mn, Se, Cu, Zn, Co, V, Cr from the decoction of "Zhebawei" TCMs were all within safe limits. The daily intakes of Cd and Sn did not exceed the level of personal acceptable daily intake instituted by the FAO and WHO. The total content in the decoction of Rhizoma Corydalis was more than the level of personal acceptable daily intake instituted by FAO and WHO, however the amount in the dislysate of "Zhebawei" TCMs' decoction after in vitro digestion were under the standard. The analysis of total content may exaggerate the risk of toxicity. CONCLUSION: The results will provide the basis for further researches such as bioavailability and safety of inorganic elements in "Zhebawei" TCMs, and will provide references for ensuring the rational use of TCM according to the analysis of inorganic elements.

Objective To investigate the protective effects and molecular mechanism of peroxisome proliferate-activated receptor α(PPARα) activation on acute myocardial damage induced by isoproterenol (Iso) in rats. Methods Thirty male Wistar rats, weighting 160～180 g, were randomly divided into control group, Iso group, fenafibrate(FF) group(each n=10) according to physique quantity. Acute myocardial injury caused by Iso abdomen cavity injection induced ischemia was established and the protective effects of peroxisome proliferate-activated receptor α activation were accessed by the level of ereatine kinase(CK), lactic dehydrogenase(LDH) in serum as well as the activities of myoperoxidase(MPO) in myocardium, and the protein expressions of PPABα in myocardium by Western blot. Results The level of serum CK in control group, lso group and FF group, was (62.41±9.47),(101.71±11.05),(75.64±11.73)kU/L, respectively(F= 34.34, P<0.01). Whereas the level of serum CK in Iso group and FF group was higher than that in control group(P<0.01 or<0.05), the level of serum CK in FF group was lower than that in Iso group(P<0.01). The levels of LDH in these three groups were (5912.20±204.44), (6365.78±137.10), (6089.76±169.60) U/L, respectively(F= 17.54, P<0.01). Compared with the control group, the levels of LDH in Iso and Fir groups were significantly increased(P<0.01 or<0.05). But the level of LDH in FIr group was decreased compared with that in Iso group(P<0.01). The activities of myocardial MPO in these three groups were (1.95±0.10),(3.89±0.17),(2.49±0.19)U/g, espectively(F=391.68,P< 0.01). The activities of myocardial MPO in Iso and FF groups were higher than that in the control group (all P< 0.01), while the activities of myocardial MPO in FIr group were lower than that in lso group(P<0.01). The protein expressions of PPARα in myocardium of these three groups were 251.57±10.95,191.97±10.74,215.08±9.61, respectively(F=82.69, P<0.01). Conclusion PPARα activation by its actor FF can exert protective effects on the acute myocardial ischemia injury induced by lso in rats through inhibiting the release of inflammatory cell factors.
