Journal of Chinese Physician 2010;12(2):149-152
Objective To explore the changes of GRO-α and VEGF in the peritoneal fluid of women with endometriosis and their correlation. Methods The levels of GRO-α and VEGF were detected by enzyme linked immunosorbent assay ( ELISA ) method in 39 cases of endometriosis and 25 normal cases of without endometriosis. Results The levels of GRO-αand VEGF in the peritoneal fluid of EMs group were ( 108.77 ± 20. 58 ) pg/ml and ( 199. 67 ± 99. 26 ) pg/ml separately, and it was significantly higher than those in control group ( 71.07 ± 18. 96 ) pg/ml, ( 115.46 ± 32. 39 ) pg/ml. The differences were statically significant( P <0. 05). The level of GRO-α in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was sig-nificantly lower than that in stage Ⅲ and Ⅳ[(99.43 ± 16.05)pg/ml vs (117.65 ± 20.8)pg/ml, P <0. 05] , while the level of VEGF in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was significantly higher than that in stage Ⅲ and Ⅳ[(246. 89 ± 114. 34) pg/ml vs ( 152. 82 ± 54. 55 ) pg/ml, P < 0. 05] .There was positive correlation between the level of GRO-α and r-AFS ( r = 0. 439, P < 0. 05 ), but no cor-relation between the level of VEGF and r-AFS ( r = -0. 210, P >0.05). There was no correlation be-tween peritoneal fluid levels of GRO-α and VEGF in the EMs group ( r =-0. 05, P>0. 05). Conclusion Compared with control group, the levels of GRO-α and VEGF in peritoneal fluid of women with endome-triosis were significantly increased, which indicated that the increased GR0-α and VEGF secretion involved in the pathogenesis of this disease. There was correlation between the peritoneal fluid level of GRO-α and the degree of EMs.

Using different models of focal cerebral ischemia, the temporal and spatial rules of metabolism and energy changes in the post-ischemia brain tissue were measured by proton magnetic resonance spectroscopy (1HMRS) to provide valuable information for judging the prognosis of acute focal cerebral ischemia and carrying out effective therapy. Nine healthy Sprague-Dawly rats (both sexes) were randomly divided into two groups: The rats in the group A (n = 4) were occluded with self-thrombus for 1 h; The rats in the group B (n = 5) were occluded with thread-emboli for 1 h. The 1H MRS at 30, 40, 50, 60 min respectively was examined and the metabolic changes of NAA, Cho and Lac in the regions of interest were semiquantitatively analyzed. The spectrum integral calculus area ratio of NAA, Cho, Lac to Pcr + Cr was set as the criterion. The values of NAA.Cho in the regions of interest were declined gradually within 1 h after ischemia, especially, the ratio of Cho/(Pcr + Cr), NAA/(Pcr + Cr) at 60 min had significant difference with that at 50 min (P < 0.05). The ratio of Lac/(Pcr + Cr) began to decrease at 40 min from initial increase of Lac in both A and B groups. MR proton spectrum analysis was a non-invasive, direct and comprehensive tool for the study of cellular metabolism and the status of the biochemical energy in acute ischemia stroke.
