Reperfusion is the most effective treatment for acute myocardial infarction, markedly reducing mortality and morbidity. Reperfusion however induces necrotic and apoptotic damages to cardiomyocytes, that were viable prior to reperfusion, a process called myocardial ischemia/reperfusion injury(MI/RI). Over the past 30 years, hundreds of experimental interventions (both pharmacologic and nonpharmacologic) have been reported to protect the ischemic myocardium in experimental animals; however, with the exception of early reperfusion, none has been translated into clinical practice. The population-based survey assessed men have about twice the total incidence of morbidity and mortality of women, and the sex gap in morbidity tends to diminish after age 45 years. So hormone replacement therapy (HRT) is given to treat the MI/RI, and lots of studies shows that the side effect is greater for estrogen, compared with phyestrogen. In this article, we review the important pathogenesis of myocardial ischemia reperfusion injury, the prevention and limitations of HRT. And we highlight the mechanism of phyestrogens treatment the MI/RI in experiment. The aim is to provide the theoretically new way of develop the safe and effective products for the researchers.

BackgroundIn an ideal eye there would be no light scattering at all,but the eye media is not optically ideal.Intraocular straylight causes a veil of light and reduction in the contrast of the retinal image and thus decrease the quality of vision.ObjectiveThe present study was to investigate the repeatability and reproducibility of C-Quant straylight meter( Oculus,Germany)in measuring retinal straylight of myopia and post-laser in situ keratomileusis(LASIK) corneas.MethodsThis is a prospective research.The consecutive 35 eyes of 21 myopic patients and 34 eyes of 22 patients who received LASIK were included in this trail.Retinal straylight was measured for 7 times at a period of time and analyzed quantificational to evaluate the repeatability of measurement.Thirty-eight eyes of 19 patients were measured again at 3-7 days for 3 times at a period of time to assess the reproducibility of C-Quant straylight meter.The mean standard difference (SD) and coefficient of variation (CV) were used as the credibility evaluation.This clinical study complied with Helsinki Declaration and the informed consent was obtained prior to the medical procedure.ResultsThe straylight Log(s) of 7 times measurement were all less than 0.95.The mean Log(s) were 0.92±0.12 and 0.93±0.17 respectively in myopia group and post-LASIK group,without statistically significant differences among 7 times measurement( F=0.335,P=0.812;F=1.000,P=0.409).The mean SD for the 7 times measurement was 0.07 Log units.SD and CV increased with the number of measurements.The differences of mean SD and CV between 3 times result and 6 times result were significant different (t =-2.080,P =0.045;t =-2.190,P =0.035 ).No difference was found between different time periods( t =-0.531,P=0.598 ).The difference of the results between two measurements from the same patient was 0.013.ConclusionsC-Quant is a noncontact,noninvade,rapid and convenient method for the measurement of straylight in myopia and post-LASIK eyes due to the high repeatability and reproducibility.

Objective To investigate the changes of hypoxia-inducible factor(HIF)-1α and hexokinase-Ⅱ(HK-Ⅱ)expression in human esophageal squamous cell carcinoma and its effect in glycolysis.Methods TE13 cells and Eca109 cells were cultured under hypoxic condition(1 ％O2)for different hypoxic time(6,12,24 and 48 hours).Cells cultured under normal oxygen condition(20％O2)were set as control.The changes of HIF-1α and HK-Ⅱ expressions at protein level were detected by Western blot.HIF-1α genes were specifically silenced with RNA interference technology(RNAi),and then the changes of HIF-1α and HK-Ⅱ expression were determined by realtime PCR and Western blot.Under normal oxygen and hypoxic condition,the changes of lactic acid concentration in cell culture medium were detected by spectrophotometric method.Results Under hypoxic condition,the expression of HIF-1α and HK-Ⅱ gradually increased as hypoxic time extended(P＜0.05),reached a peak at 12h and then gradually decreased as time extended.Compared with that under normal oxygen condition,the expression of HK-Ⅱ in TE13 cells and Eca109 cells significantly increased under hypoxic condition(P＜0.05),which was more significant after 12 hours hypoxia.The result of realtime PCR indicated that under normal oxygen condition the expression of HIF-1α at RNA level in TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference(P＜0.05).The expression of HK-Ⅱ at RNA level was consistent with the result of HIF-1α.Under normal and hypoxia condition,the expression of HK-Ⅱ at protein level in TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference,and the difference was statistic significant(P＜0.05).The lactic acid secretion of TE13 cells and Eca109 cells under hypoxia condition(14.707 ± 3.594 and 15.062 ±3.901)was higher than that under normal oxygen condition(6.070±1.839 and 6.891±1.592,P＜0.05).The lactic acid secretion of TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference,and the difference was statistic significant(P＜0.05).Conclusion The expressions of HIF-1α and HK-Ⅱ in human esophageal squamous cell carcinoma significantly increased under hypoxia conditions.The expression of HK-Ⅱ is closely correlated with lactic acid concentration and HIF-1α expression.HIF-1α may affect cell glycolysis through HK-Ⅱ.

Objective:The immunological effects of HCV-DNA vaccine with different adjuvants were detected by ELISPOT in mice.Methods:Female BALB/c mice were primed with naked HCV-DNA, HCV-DNA encapsulated by liposome DDAB/EPC or DC-Chol/DOPE, HCV-DNA mixed with Montanide ISA 720 or aluminum hydroxide, respectively, and boosted twice accordingly in a four-week interval. Cytokine production by splenocytes was assessed by ELISPOT.Results:In most cases, splenocytes from mice vaccinated with DDAB/EPC liposome produced more IFN-?. These splenocytes also have significant higher IL-2 production compared with the other groups. In expansion with NS5b, splenocytes from alum group have significance in IL-4 production compared with other groups. The profile of cytokine production revealed that the INF-? overwhelmed IL-4 in naked DNA, DDAB/EPC, and DC-Chol/DOPE groups while IL-4 surmounted IFN-? in alum and Montanide groups.Conclusion:Encapsulation with liposome DDAB/EPC has the strongest adjuvant effect in inducing Th1 dominated immunity. Alum and Montanide can convert the Th1 nature of DNA vaccine to Th2-biased immunity.

Objective To study the influence of different starting time of hyperbaric oxygenation (HBO)therapy on acute cerebral infarction patients.Methods A total of 120 patients with first-time acute cerebral infarction were randomly and evenly divided into 4 groups:groups A,B,C and D.All the patients were treated with routine clinical regime.In addition,the patients in groups A,B andC started with HBO within 24 hours,between 24 and 72 hours and after 72 hours post-onset of the disease,respectively,while those in group D without HBO.All the patients were evaluated in terms of their neurological function and their perform- ante in activities of daily living,using the National Institutes of Health stroke survey(NIHSS)and Barthel In- dex(BI).Results At 14,28 and 90 davs after treatment,the patients in group A scored significantly better with NIHSS and BI than those in groups B,C and D(P0.05).No serious adverse reaction was found in the four groups.Conclusion The earlier the HBO therapy was started, the better the treatment.There will be no significant effects of HBO if it was started after 72 hours pust-onset of the disease.HBO therapy appears safe.

Objective To study the role of hematopoietic growth factor(HGF)of placenta chorionic villus in fetal hematopoiesis during embryo ontogeny by observation of the appearance time and the content changes with the fetal growth, which was compared with HGF in cord blood. Methods Thirty embryo villus (2 g each) and 30 cord blood (2 mL each) were collected separately from early pregnant stage(6- 8 weeks), middle pregnant stage(16-22 weeks)and late pregnant stage (37-42 weeks). The levels of HGF were detected by enzyme - linked immunosorbent assay. Results HGF were produced on the early pregnant stage and the content of FL-T3,IL-3 increased gradually.There were significantly differences at different stages(P

Objectives To investigate the ameliorative effect of cannabinoid 2 receptor(CB2R)agonist JWH-015 on the cog-nitive impairment of Alzheimer' s disease(AD)model mice and to assess the correlation with microglial phenotype transformation. Methods Twenty adult male C57BL/6J mice were randomly divided into four groups:C57BL/6J solvent group,JWH-015 control group,AD model group,and AD model treated with JWH-015 group. Amyloidβ1-42 oligomers of 4μg and the same volume of saline were intraventricularly administered to construct the AD mouse model and the solvent groups. CB2R agonist JWH-015 or the corre-sponding vehicle at a dose of 0.5 mg/(kg·d)was administered by intraperitoneal injection for 3 weeks. Non-spatial learning and memo-ry was measured using novel object recognition task. Furthermore,the mRNA expression levels of M1 microglia marker inducible ni-tric oxide synthase(iNOS)and M2 microglia marker chitinase-3 like protein(Ym1/2)in brain samples of cortex and hippocampus were evaluated using real-time quantitative PCR(qPCR). In the meantime,fifteen CB2R knockout(CB2RKO)mice and five CB2R wild-type(CB2RWT)littermates were assigned to identify the specificity of CB2R in the research. Based on the genotype and different treatment,the animals were divided into four groups:CB2RKO solvent group,CB2RKO AD model group,CB2RKO AD model treat-ed with JWH-015 group and CB2RWT solvent group. Results Compared with solvent group,there was a significant decrease in nov-el object recognition index in C57BL/6J AD model group(P<0.01). The mRNA expression levels of M1 phenotype microglia marker iNOS in cortex and hippocampus were significantly up-regulated(both P<0.05)and the mRNA expression levels of M2 phenotype mi-croglia marker Ym1/2 were significantly down-regulated(both P<0.01). Interestingly,administration of JWH-015 could reverse the impairment of novel object recognition index(P<0.05);compared with C57BL/6J AD model group,administration of JWH-015 also decreased the iNOS mRNA expression levels(both P<0.05)and increased the Ym1/2 mRNA expression levels(both P<0.05)in cortex and hippocampus;compared with CB2RKO solvent group,the novel object recognition index of CB2RKO AD model group was decreased(P<0.05);the mRNA expression levels of iNOS in cortex and hippocampus were significantly up-regulated(both P<0.05),the mRNA expression level of Ym1/2 in cortex was significantly down-regulated in cortex(P<0.05);compared with CB2RKO AD model group,administration of JWH-015 had no effect on novel object recognition index and the mRNA expression level of M1/M2 in cortex and hippocampus,respectively. Conclusion JWH-015 improves the cognitive impairment of Aβ-induced AD mice by the specific activation of CB2R,the mechanism of which is related to the direct regulation of CB2R on the M1/M2 microglial phenotype transformation and microglia-mediated neuroinflammation in brain.

Background and purpose: Lysine specific demethylase 1(LSD1) is an important chromatin modifier. It epigenetically regulates gene expression pattern through chromatin modification and participates in maintenance of tumor malignant properties, such as oncogenesis, development, invasion, migration and metabolic transformation. SIRT3 (sirtuin 3) is a mitochondria localized tumor suppressor and regulates tumor metabolic transformation and oxidative stress. The correlation between LSD1 and SIRT3 has never been reported before. This study aimed to elucidate the correlation between LSD1 and SIRT3 with gene transcriptional regulation methods. Methods: RNA interference technique, co-immunoprecipitation assay(CoIP), chromatin immune-precipitation assay(ChIP) and ifrelfy luciferase activity assay were employed to elucidate the correlation between LSD1 and SIRT3 in pancreatic cancer. Results:mRNA and protein levels of SIRT3 were signiifcantly elevated in LSD1 knock-down PANC-1 cells. LSD1 interacts with PGC-1α, an important regulator of SIRT3 gene expression. LSD1 and PGC-1αoccupied the same region in SIRT3 promoter region through ChIP analysis. Luciferase activity assay validated LSD1 as a negative regulator of PGC-1αin SIRT3 gene transcriptional regulation. Conclusion:LSD1, as an important tumor promoter, negatively regulates the expression of tumor suppressor gene SIRT3, these results provide important clues for the role that LSD1 plays in aberrant metabolism and oxidative stress.

For effective inhalable dry-powder drug delivery, tetrandrine-PLGA (polylactic-co-glycolic acid) nanocomposite particles have been developed to overcome the disadvantages of nanoparticles and microparticles. The primary nanoparticles were prepared by using premix membrane emulsification method. To prepare second particles, they were spray dried. The final particles were characterized by scanning electron microscopy (SEM), dry laser particle size analysis, high performance liquid chromatography (HPLC), X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared analysis (IR) and confocal laser scanning microscope (CLSM). The average size of the primary particles was (337.5 ± 6.2) nm, while that second particles was (3.675 ± 0.16) μm which can be decomposed into primary nanoparticles in water. And the second particles were solid sphere-like with the drug dispersed as armorphous form in them. It is a reference for components delivery to lung in a new form.
