Background It is well known that sclera remodeling occurs during axial elongation in myopia under the control of growth hormone or its downstream effectors.The role of transforming growth factor-β (TGF-β) in myopia has been determined in previous studies.Bone morphogenetic protein (BMP) is one of members of the TGF-β superfamily,but if it plays an important role in the genesis and development of myopia is not completely clear.Objective This study was to identify the presence of BMPs in normal guinea pigs sclera and investigate the change of BMPs in the sclera in form-deprivation myopia (FDM) of guinea pigs.Methods Thirty young guinea pigs were randomized into normal control group and experimental group using table of random number.FDM models were established by occluding unilateral eyes of guinea pigs with a translucent lens for 14 days in the experimental group,and the fellow eyes served as the controls.Diopter of all eyes was tested by retinoscopy optometry,and ocular axial length was measured by A-sonography before and after modeling.Posterior sclera tissue of the animals was obtained on 14 days,and the relative expression level of BMPs mRNA and protein were assayed by reverse transcription PCR (RT-PCR) and Western blot.The use and care of the animals complied with ARVO Statement.Results On 14 days after occluding of unilateral eyes,the refraction diopter of the experimental group was (-0.48±0.51) D,and that of the fellow eyes was (3.22 ±0.34) D,showing a significant difference between them (t =-12.814,P =0.000).Also,a significant difference in the diopter was seen between the experimental group and normal control group ([-0.48±0.51]D vs.[2.97±0.70]D,t =-11.878,P=0.000).Axial length was (8.30 ± 0.05) mm in the experimental group,(8.11 ±0.06) mm in the fellow eyes and (8.06±0.06) mm in the normal control group,showing a significant increase in the experimental group compared with the fellow eyes and normal control group (t =7.230,P =0.000 ; t =9.084,P=0.000).The expressions of BMP-2 mRNA,BMP-4 mRNA,BMP-5 mRNA in posterior sclera were detected in the normal guinea pigs.Fourteen days after the induction of myopia,the relative levels of BMP-2 mRNA and BMP-5 mRNA in sclera were 0.41 ± 0.11 and 0.65 ± 0.06 in the experimental eyes,which were significantly lower than 0.62 ± 0.07 and 0.84 ± 0.03 in the fellow eyes with the descent range of 34.48％ and 23.67％ respectively (t=2.838,P=0.017; t=2.524,P=0.028).The relative values of BMP-2 protein and BMP-5 protein were 0.44±0.06 and 0.70±0.05 in the experimental eyes,and those of the fellow eyes were 0.61±0.05 and 0.82±0.03,showing significant decline in the experimental eyes with the lowing range of 23.42％ and 15.21％,respectively (t =2.465,P =0.030;t =2.445,P=0.031).No significant differences were found in the expression of BMP-4 mRNA and protein in posterior sclera between the experimental eyes and the normal control eyes (mRNA:t =0.704,P=0.460;protein:t=0.987,P=0.365).Conclusions The expressions of the BMP-2 and BMP-5 in sclera down-regulate significantly in FDM eyes,which suggest that BMP-2 and BMP-5 participate in sclera remodeling during myopia induction.

In this study, the human umbilical vein endothelial cell model was used to study the regulating effect of lipophilic components in Salvia miltiorrhiza on angiogenesis, and explore its possible mechanism. The cell model was established to determine the effect of lipophilic components in S. miltiorrhiza on the proliferative activity and migration capacity of endothelial cells. Then the realtime fluorescence quantification PCR technology was applied to detect the changes in the gene expressions of angiogenesis-related cytokines VEGF-A, VEGF-C and MMP-9. The results showed that 5 mg x L(-1) lipophilic components in S. miltiorrhiza could inhibit the proliferation and migration of endothelial cells, and reduce the expression of VEGF-A and MMP-9 genes. It indicated that lipophilic components in S. miltiorrhiza may inhibit the proliferation and migration of endothelial cells by inhibiting the expression of VEGF-A and MMP-9 genes, so as to show the inhibitory effect on angiogenesis.

SUMMARY Objective:To investigate the influence of cryoprotectants and cooling rates in vitrificationmethod on the spindles of rabbit M Ⅱ oocytes.Methods:Rabbit oocytes were verified by using cryoloopwith ethylene glycol(EG)singly or EG combined with dimethyl sulphoxide(DMSO)as cryoprotectants,and cooled by taking oocytes directly into liquid nitrogen or by vitrification machine.After frozen rabbit o-ocytes thawed,the microtubulin and chromosome of the spindles were fixation and stained by immunofluo-rescent method.Confocal microscope was used to reveal spindle configuration.Results:In the two proto-cols of single EG used and EG combined with DMSO,the spindles were severely injured.But in protocolof EG combined with DMSO and at ultra-rapid cooling rate,the normal configuration of spindle rate ofthawed rabbit oobytes was similar to that of the control group.Conclusion:The protocol of EG combinedwith DMSO as cryoprotectants and with extremely high cooling rate by vitrification machine can producethe best effect on conservation of spindle configuration in vitrification of rabbit oocytes.

OBJECTIVETo investigate osthole effect on femoral tissue resorption activity of rat in vitro.

METHODSSix SD rats weighted (80 ± 5) g were used to isolate and culture femoral tissue (diaphyses and metaphysis) in vitro. The cultured tissue were devided into control group, estradiol group and osthole group. The femoral tissue was treated with final concentration of 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol culture in vitro at 48 hours after cultured. Tartrate-resistant acid phosphatase (StrACP) activity, glucose and Lactic acid content, StrACP, MCSF (Macrophage colony stimulating factor) and CTSK (Cathepsin K) mRNA was detected by Real-Time RT-PCR were detected.

RESULTSConcetration of Alkaline phosphatase activity were 2226 and 2498 in 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol respectively. As compared with control group, the activity of StrACP of 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol were inhibited at 6, 9, 12 days (P < 0.05); under treatment of in l x 10(-5) mol/L osthole, the content of Lactic acid were increased and the content of glucose were decreased at 3, 6, 9 days (P < 0.05); StrACP, MCSF and CTSK mRNA expression level were inhibited at 6, 9 days (P < 0.05).

CONCLUSIONOsthole can inhibit bone resorption and raise the level of nutrition metabolism of femurs tissue.

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.

Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.
