Results The NIH-CPSI score was 21.7±8.8 in the group,64.05% of the CPS patients had pain of perineal region,hypogastrium,inguinal groove and lumbosacral area.46.41% of them had urination irritation.41.18% of them felt dissatisfied,unhappy,even terrified with the symptoms of chronic prostatitis.Conclusion Controlling pain of perineal region and hypogastrium is important in the treatment of CP.

With longger fruit and more key fruits,moreover, the two traits showed significantly positive correlation (r=0.888). Of the 11 floral and fruit quantitative traits, the length and width of perianth segment and 6 other traits were different significantly among the three groups,which were successfully used in group-discrimination by means of the method of principal component analysis.

在所研究的11 个花果数量性状中，花被片长度和宽度等10 个性状在三大类群间差异极显著，主成分分析结果表明第1 主成分(贡献率69.11%)综合了各性状的主要信息，依据第1 主成分可以对三大类群进行区分，其中北美鹅掌楸类群第1 主成分值最大(变幅0.7156～1.3916，平均1.0408)，杂交鹅掌楸类群(变幅-0.0865～0.3959，平均0.2646)居于两个亲本类群之间，鹅掌楸类群(变幅-1.5443～-0.8855，平均-1.2426)最小。
