This study was to investigate the chemical constituents of the aerial part of Zygophyllumfabago, by phytochemical methods. The compounds were isolated by silica gel and Sephadex LH-20 column chromatographies from the EtOAc extract. Their structures were characterized by various spectroscopic data (1H-NMR, 13C-NMR, MS) and comparison with the literature. As a result, thirteen compounds were isolated and their structures were identified as 1-hydroxyhinesol(1), hinesol(2), atractylenolactam(3), beta-eudesmol (4), 5alpha-hydroperoxy-beta-eudesmol(5), 12-hydroxy-valenc-1(10)-en-2-one(6), pubinernoid A(7), (6S,7E)-6-hydroxy-4,7-megastigmadien-3,9-dione(8), 3-hydroxy-5alpha, 6alpha-epoxy-beta-ionone (9), (3S,5R, 6S, 7E)-3, 5, 6-trihydroxy-7-megastigmen-9-one(10), (6R,7E,9R)-9-hydroxy-4,7-megastigmadien-3-one(11), (S)-3-hydroxy-beta-ionone(12), and blumenol A(13). Compounds 1-7 were sesquiterpenoids and 8-13 were megastigmane type norsesquiterpenoids. All the compounds were obtained from Z. fabago for the first time, and compound 1 was a new natural product.

OBJECTIVETo explore the clinical significance of improvement gastrostomy in pancreaticoduodenectomy.

METHODSClinical data of 82 patients who underwent pancreaticoduodenectomy and jejunostomy from November 2004 to December 2006 were collected, among which 36 patients received improvement gastrostomy (treatment group), 24 patients accepted traditionary gastrostomy (control group 1) and 22 patients without any gastrostomy (control group 2). Operative time, postoperative duration of gastrointestinal decompression tube, postoperative gastroparesis, pancreatic fistula, biliary fistula, and abdominal cavity infection were compared.

RESULTSThe incidence of postoperative gastroparesis in the treatment group and control group 2 were can significantly lower than that in the control group 1 (P < 0.05). The postoperative duration of gastrointestinal decompression tube of the treatment group was significant shorter than that of control group 2 (P < 0.01). There were no significant difference in other items.

CONCLUSIONSThe improvement gastrostomy in pancreaticoduodenectomy is simple and secure. It can significantly shorten the postoperative duration of gastrointestinal decompression tube and also obviously reduce the incidence of postoperative gastroparesis compared with traditionary gastrostomy.
