Results? 6 cases in X-ray film revealed round or oval stones in areatus distribution in the areas of renal papillae and medulla. 3 cases of IVP revealed cystic or hair-brushed dilation. 5cases in B-ultrasound revealed little anechoic area and strong echo light spot in radial distribution with acoustic shadow. Unenhanced CT of 6 cases revealed spotted or areatus stones surrounding minor renal calices with collecting tube system dilation and enhanced CT showed artifacts of stones magnification because of the collection of contrast medium around the stones. Conclusion?

The expression of Bcl-2mRNA and P53mRNA in hippocampus after 16Hz, 130dB infrasound treatment In 1 day group, Bcl-2mRNA and P53mRNA were expressed lightly in CA1-CA3 areas in hippocampus and dentate gyrus. Blood vessels dilated lightly. In 7d group, Bcl-2mRNA and P53mRNA were more expressed in areas mentioned above. Dilation of capillaries and small vessels was more obvious. Bcl-2mRNA and P53mRNA were strong positive in endothelial cells of vessels. In 14d group, Bcl-2mRNA and P53mRNA expression was obviously increased in pyramidal cells of hippocampus and granular cells of dentate gyrus, showing deep blue staining. a The endothelial cells in some vessels were also strong positive for Bcl-2mRNA and P53mRNA. Dilation of capillaries and small vessels was lessened. In 21d group, Bcl-2mRNA and P53mRNA expression was decreased in pyramidal cells. In 28d group, little change about the expression and distribution of Bcl-2mRNA and P53mRNA was observed. Lots of Bcl-2mRNA and P53mRNA were scattered in cortex of temporal lobe around hippocampus and callosal gyrus area. Dilation of capillaries and small vessels was lessened obviously. The expression of Bcl-2mRNA and P53mRNA in hippocampus after 16Hz, 90dB infrasound treatment.

The incidence rates and duration of ventricular dilation-induced arrhythmias in each of verapamil, chelerythrine or glibenclamide group were similar to those in control group. Conclusion Ventricular dilation may induce arrhythmias in isolated rat hearts, which is inhibited by ischemic preconditioning. The transient increase in [Ca(superscript 2+)] appeared to be a triggering factor in the process of ischemic preconditioning. K channel PKC might also play an important roles in this process.

对大鼠心室进行膨胀可诱发心律失常；缺血预适应对心律失常的发生具有抑制作用；细胞内钙离子浓度的短暂升高可能是缺血预适应发挥抑制作用的驱动因子；ATP敏感性钾通道及蛋白激酶C在缺血预适应过程中可能发挥了重要作用。

Results An intracerebral echoless cyst could be visualized in all the three cases, in which" high-speed and low-resistance" blood signal could be detected by CDFI. There was direct communication between the vein of Galen and several basis cranii cerebral arteries without cerebral ventricle dilation. The dilated heart-breast rate could be visualized in all the three cases, two of which complicating with the dilation of superior vena cava and tricuspid regurgitation; two of which complicating with pleural fluid and abdominal dropsy; one of which complicating with edema of skin and polyhydramnios; one of which complicating with reversing blood signal of umbilical artery in diastolic phase.

This article studied differences in postpartum fatigue and birth outcomes between women who pushed immediately and those who delayed pushing during the second stage of labor. Data were collected from primiparous women in their 38th to 42nd gestational week who did not receive epidural analgesia during labor and were free of complications during pregnancy. Using a quasi-experimental design, 72 participants selected by convenient sampling were assigned based on individual participant's preference to either an experimental or control group. For the experimental group, pushing was delayed until the point after full cervical dilation at which the mother felt a strong physical pushing reflex, the fetal head had both descended to at least the +1 level in the pelvis and turned to the occiput anterior position, and uterine contractions were at least 30 mmHg. For the control group, the physician instructed mothers to begin pushing after full cervical dilation at the point when the fetal head was in the occiput anterior position and uterine contractions were at least 30 mmHg.
