Objective: To quantitatively analyze the fetal lung echo and right lung volume in the third trimester by real-time three-dimensional ultrasound (3-D US) and evaluate the feasibility of fetal lung maturity. Methods: A total of 732 women with normal singleton pregnancies between 28 and 42 weeks of gestation underwent ultrasound examination. The 3-D US equipment with a 3.5-5 MHz transabdominal transducer was used for the fetal biometric measurement. The echogenicity ratio between fetal lung and liver was compared. The fetal lung volume was calculated by the rotational multiplanar technique for volume measurement (VOCAL). Results: The right fetal lung volume increased with the increase of gestational age with a linear positive correlation (r = 0.884, P<0.01). After 34 weeks, the echogenicity ratio of fetal lung to liver was more than 1.1. Conclusion: The echogenicity of lung/liver and fetal lung volume could be used as normal fetal predictable indicators for fetal lung maturity.

Objective: To study the effect of apigenin on the expression of microglia in penumbra and cerebral water content after acute transient focal cerebral ischemia-reperfution injury in rats. Methods: The acute transient focal cerebral ischemia-reperfusion models in rats were established with the modified suture method. Male Sprague-Dawley rats were randomly divided into Sham group, model group, and apigenin groups (there were 6, 24, 48, 72 h, and 7 d reperfusion treatments in the model and apigenin groups, n = 12). All of them are 11 groups. The neurological behavior scores were valued. By FITC labeled isolectin B4 (FITC-ILB4) histochemistry staining, the infiltration of monocytes and the changes of cell morphology and number of brain-derived microglia in penumbra of six rats in every group were observed under laser scanning confocal microscope (LSCM). Water content was measured in isolated brain tissue of other six rats. Results: The positive cells of ILB4 (ILB4+) including microglia cells (Rhod 6G-) and infiltration of monocytes (Rhod 6G+) were found in cerebral ischemic area around penumbra of rats after 6 h ischemia-reperfusion in model group; The morphology changed to Amoeba-like; Microglia increased significantly after 48 h and reached to peak in 72 h, which mainly belonged to the proliferation of brain-derived microglia in Amoeba-like morphology. Microglia cell decreased in 7 d, and microglia in apigenin group obviously decreased more than that in model group (P<.05, 0.01) with the similar morphological change in corresponding time points. In 48 and 72 h of cerebral ischimia, the water content in brain tissue of rats in apigenin group was markedly lower than that in model (P<0.01). There was negative line correlation between the neurological behavior score and the number of ILB4 + cells in penumbra of model group (r=-0.415, P<.05). Apigenin could reduce the degree of neurological deficiency in model group and mitigate the brain injury effectively. Conclusion: A part of microglia cells inpenumbra are associated with brain injury; Apigenin shows the protection on acute transient focal cerebral ischemia-reperfution injury in rats, which maybe relates with down-regulating the microglia cell number and inhibiting the excessive activation of microglia cell.

BackgroundThe progressive death of retinal ganglion cells (RGCs) is the primary pathological characteristics of visual defects in glaucomatous eye.Research showed that endoplasmic reticulum stress (ERS) is involved in this progression.Glucose-regulated protein 78 ( GRP78 ) is a special marker of ERS.To understand the change in expression of GRP78 in the retina under the pressure induced is very important for the protection of visual function.Objective The present study was to observe the expression of GRP78 in rat retina with acute high intraocular pressure (IOP) and investigate the possible effect of ERS in acute glaucoma damage. MethodsFiftysix Wistar rats were randomly assigned to normal control group,anterior chamber punctured group and 12 hours,1 day,3,7,14 days groups following acute IOP rising.The acute high IOP models were established in the right eyes of 4.0 Wistar rats by paracentesis of the anterior chamber and infusion of normal saline solution into the anterior chamber.The histopathology changes of the retina were examined by hemotoxylin and eosin staining.The expression of GRP78 protein and mRNA in the retina were detected by immunohistochemistry and real-time fluorescence quantitative PCR.ResultsThe retinal layers and cells were clear with normal alignement in the rats of the normal control group and the anterior chamber punctured group.The edema and thickening of retinas appeared in 12 hours after molding and peaked in 1 day after molding.Then the retina decreased in thickness and atrophied from 3 days through 14 days.The expression levels of GRP78 protein (A value) were 0.195±0.006 in the nounal rats and gradually increased from 12 hours through 3 days (0.268±0.017) following molding with the peak value at 1 day (0.499±0.039 ),showing significant differences in comparison with the normal control group (t =0.098,0.304,0.073,P＜0.05),and the reduction in expression at 7 and 14 days were not significantly different from the normal control group ( t =0.002,0.001,P＞0.05 ).The relative value of GRP78 mRNA ( 2△△C1 ) in the retina was 1.011 ±0.013 in the normal control group and gradually up-regulated from 12 hours through 3 days with the peak value at Iday (2.141±0.171 ) and then down-regulated from the third day onwards.A significant difference was seen in 2-△△C1value between the normal control group and 12 hours group,1 day group or 3 group ( t =0.525,1.130,0.409,P＜0.05 ).However,the 2-△△C1 values of GRP78 mRNA at 7 and 14 days was similar to that of the normal control group (t=0.020,0.004,P＞0.05).ConclusionsGRP78 participates in the process of RGCs damage following acute high IOP.The results suggest that interfering with ERS may be helpful for protecting the retina and optical nerve from pressure-induced damage.
