Cephalotaxine ester of 2-oxo-6-methylheptanoic acid was treated with lithium diisopropylamide and Me O-(1-methoxyisopropyl)glycolate to give a mixture of homoisoharringtonine and its stereoisomers with 56% yield. The four stereoisomers separated by TLC showed identical mass spectra and almost superimposed IR but with different 1H NMR spectra. The configuration of the 2'-C and 3'-C of the four isomers were postulated based upon their 1H NMR spectra as compared with the 1H NMR spectra of isoharringtonine and its stereoisomers.

2-氧代-6-甲基庚酰基三尖杉碱(3)与0-(1-甲氧基异丙基)羟基乙酸甲酯(4)在强碱性试剂二异丙胺锂存在下，起亲核加成反应，反应中间体5在室温用酸性丙酮水解，得到一种新的三尖杉酯类生物碱一一高异三尖杉酯碱(6c)及其立体异构体(6a、6b、6d)的混合物，产率56%、通过制备薄层层析分得这四个立体异构体，它们的1H NMR和异三尖杉酯碱及其立体异构体的1H NMR类似，推定了它们的绝对构型。

In 1998, Longo described a method by which prolapsing hemorrhoids could be treated with a circular stapler, obviating the excision of either the anoderm or perianal skin. He postulated that the hemorrhoidal symptoms were primarily related to prolapse of the rectal mucosa and anoderm. The procedure for prolapsed hemorrhoids (PPH, a circular hemorrhoidopexy) resulted in simultaneous relocation and fixation of the hemorrhoids and anoderm. With the widening acceptance of hemorrhoids as prolapsed anal cushions, a circular hemorrhoidopexy has become a popular procedure for the treatment of symptomatic hemorrhoids.

在1998年Antonio Longo提出利用经肛门环形自动钉合器来治疗脱垂的痔疮，他认为痔疮的症状主要是因直肠黏膜及肛垫脱垂所引起，而环形的痔疮修补术可以将痔疮及肛垫组织重新定位回原来的正常位置，在随著普遍认为痔疮是脱垂的肛垫，环形的痔疮修补术已常用在治疗有症状的脱垂痔疮。
