ABSTRACT
Objective To discuss the variance of working expectation values and actual satisfaction degree in nursing college graduates from various aspects and evaluate their actual career mentality.Methods We investigated the working expectation values and actual satisfaction degree in nursing college graduates who graduated from Chengde medical college in 2004 and 2005.Results The working expectation values and actual satisfaction degree had statistical difference in 5 aspects(P<0.05).We subsequently compared the expectation values between each two groups and drew out the conclusion that these nursing graduates had great requirement of being understood and respected.Conclusion The nursing graduates had higher working expectation values and lower satisfaction degree.They paid more attention to be understood and respected and were in great need of emotional support and mental satisfaction.Hospital administrators should help them accurately orient theirselves,establish career development plan,attach importanee to their mental requirement and adopt effective measures to improve their satisfaction degree and promote the healthy growth of nursing college graduates.

ABSTRACT
<p><b>OBJECTIVE</b>To study the function of zinc in preventing human sperm from being damaged by sodium nitroprusside (SNP), an external NO donor.</p><p><b>METHODS</b>Analyses were made of the function of zinc in protecting sperm from being influenced by SNP in such aspects as sperm motility, head-tail connection and the breakage of sperm DNA chain by using phase-contrast microscope and single cell gel electrophoresis (SCGE).</p><p><b>RESULTS</b>Sperm motility was obviously inhibited by SNP. The percentage of comet cells increased significantly but the stability of sperm head-tail connection decreased. Zinc could promote sperm motility, protect the DNA chain and prevent the sperm head-tail connection from breaking.</p><p><b>CONCLUSION</b>Zinc can protect sperm from being damaged by NO. Its mechanism may be related to the mercaptol group of sperm chromatin.</p>
