子宫内膜异位症患者腹腔液及血清中前列腺素E2与bcl-2蛋白的含量变化及意义

目的探讨子宫内膜异位症(内异症)患者腹腔液及血清中,前列腺素E2(PGE2)和bcl-2蛋白的含量变化及其与内异症发病的关系。方法采用酶联免疫吸附法(ELISA)检测36例内异症患者(内异症组,其中Ⅰ、Ⅱ期患者16例,Ⅲ、Ⅳ期患者20例)和30例因卵巢囊肿或浆膜下子宫肌瘤手术患者(对照组)腹腔液及血清PGE2与bcl-2含量。结果内异症组患者腹腔液中PGE2、bcl-2蛋白的含量分别为(1987±532)ng/L、(177±53)U/L,对照组为(386±215)ng/L、(86±21)U/L,两组比较,差异均有统计学意义(P<0.01)。Ⅲ、Ⅳ期内异症患者腹腔液中PGE2的含量(2221±1352)ng/L]较Ⅰ、Ⅱ期患者(1694±381)ng/L]明显升高,差异也有统计学意义(P<0.01);Ⅲ、Ⅳ期内异症患者腹腔液中bcl-2的含量(190±63)U/L]较Ⅰ、Ⅱ期患者(162±49)U/L]升高,差异有统计学意义(P<0.05)。内异症组血清中的PGE2与bcl-2含量(3787±514)ng/L、(96±44)U/L]均高于对照组(129±97)ng/L、(53±40)U/L],差异均有统计学意义(P<0.01)。Ⅲ、Ⅳ期内异症患者血清中的PGE2含量(964±290)ng/L]也高于Ⅰ、Ⅱ期患者(590±362)ng/L],差异也有统计学意义(P<0.01);内异症患者腹腔液中PGE2及bcl-2的含量均高于血清。结论内异症患者腹腔中高含量的PGE2与bcl-2,可能对内异症发病有影响;内异症患者腹腔液与血清中PGE2和bcl-2含量与病变的范围有一定关系。

Increased levels of prostaglandin E2 and bcl-2 in peritoneal fluid and serum of patients with endometriosis

OBJECTIVE: To detect the concentrations of prostaglandin E2 (PGE2) and bcl-2 in sera and peritoneal fluid of women with endometriosis. METHODS: The study group included 36 samples of peritoneal fluid and serum respectively from patients with endometriosis, and control group included 30 samples of peritoneal fluid and serum respectively from patients without endometriosis (either ovary cyst or uterine myoma). The peritoneal fluids were collected at the time of laparoscopic operation, and the sera were collected before surgery. Concentrations of PGE2 and bcl-2 were determined by enzyme linked immunosorbent assay (ELISA). RESULTS: The peritoneal fluid concentrations of PGE2 and bcl-2 in study group were significantly higher than that of control group, (1987 +/- 532) ng/L vs (386 +/- 215) ng/L, (177 +/- 53) U/L vs (86 +/- 21) U/L, (P < 0.05); and the PGE2 levels of severe endometriosis were significantly higher than that of mild endometriosis, (2221 +/- 1352) ng/L vs (1694 +/- 381) ng/L, (P < 0.01). The serum concentrations of PGE2 and bcl-2 in study group were significantly higher than that of control group, (3787 +/- 514) ng/L vs (129 +/- 97) ng/L, (96 +/- 44) U/L vs (53 +/- 40) U/L, (P < 0.01). Serum PGE2 concentrations of severe endometriosis were significantly higher than that of mild endometriosis, (964 +/- 290) ng/L vs (590 +/- 362) ng/L, (P < 0.01). CONCLUSIONS: The concentrations of PGE2 and bcl-2 in peritoneal fluid are increased in endometriosis. The concentrations of PGE2 and bcl-2 are associated with the extent of endometriosis lesions.
