Only one case had length of styloid process less than 30mm and inclined angle less than 25 degree on both sides. Conclusion: Excessive length of styloid process and abnormal angle play important role in diagnosing styloid process. 64slice spiral CT three dimension VR and MPR can display styloid process clearly in three dimension space, measure the length exactly, and show the relationship between styloid process and tissue around distinctly. It is a precise and ideal way for diagnosis of styloid process.

The results showed that MS medium was the optimal basic culture medium; the regeneration frequency of leaf was the highest , then etiolated internode, internode was the lowest , their highest regeneration frequencies were 74.1%, 51.9%, 42.6%, respectively. The optimal dark treatment time for leaf and internode was 3 weeks; however the optimal dark treatment time for etiolated internodes was 2 weeks.

结果表明3种外植体的最适基本培养基均为MS培养基；叶片的再生效果最好，其次为黄化茎段，茎段最差，最高再生频率分别为74.1%，51.9%，42.6%；叶片和茎段的最佳暗处理时间为3周，黄化茎段的最佳暗处理时间为2周。
