Based on the 4MB 3.5" Perpendicular Recording/Longitudinal Recording Floppy Disk Drive with a track density of 270 TPI, we further developed a 3.5" Perpendicular Recording Floppy Disk Drive demonstrating the potential to realize a capacity of more than 8MB capacity. The key technology included: (1) a Perpendicular Recording/Longitudinal Recording Floppy Head which was without erase element and helped realize the capacity of 4MB-8MB under the condition of without using servo system for tracking. (2) The GAL Technology to expand the Application-Specific Integrated Circuits. (3) The improvements of the read write channel.

Objective Modeling a surgery hypertensive rat model, observe the changes of the expression of ACE and ACE2 in various groups, thus for further research of the pathogenesis of hypertension. Methods Twenty-eight Sprague- Dawley rats were used, which were divided randomly into four groups. One group served as control (n=7), others as hypertensive group (n=7), enalapril group [n=7,15mg/(kg・d)] and losartan group [n=7,15mg/(kg・d)]. All rats were operated as surgery hypertension except rats of control group. Renal artery was ligated. Enalapril and losartan were used as treatments of rats of enalapril group and losartan group after surgery. Blood pressure of rats was measured by arteria caudilis uninjured. The expression of renal ACE and ACE2 mRNA were measured by RT-PCR. The expression of renal ACE and ACE2 protein were measured by immunohistochemistry. Results Blood pressure of rats was increased after operation. The expression of ACE and ACE2 mRNA and protein in various groups were different. The expression of ACE mRNA and protein of Hypertensive group were higher than others. The expression of ACE2 mRNA and protein of losartan group were higher than others. Conclusion Model of surgery hypertensive rats were success by the ligation of renal artery. It's a Simple, reliable and cheap method of hypertensive rat model. The imbalance between the expression of ACE and ACE2 is one of the important roles of pathogenesis of hypertension.

The objective of this study was to compare the effect of papain, bromelain, kiwifruit protease, ficin and ginger extract with different concentration (0, 20, 40, 60, 80, 100 U/g) for improving the quality properties of beef rump steaks. The pH, cooking loss, Warner–Bratzler shear force, texture, colour, myofibrillar fragmentation index (MFI), collagen heat solubility, content of soluble protein (CSP), electrophoresis and sensory evaluation are invested. The result showed that all of plant-origin proteases and ginger extract can improve quality characteristics of rump steaks, and ginger extract was found to be the most effective at reducing cooking loss and contributing to the desirable red color and sensory properties, while papain and bromelain were found to be the most effective at decreasing Warner–Bratzler shear force. Ginger extract can be applied in the industrial scale and household level as a convenient and effective method to improve meat qualities. Furthermore, high-quality rump beef steaks at a keen price would be more available for Chinese consumers.
