Objective To study the protective effect of leuprorelin particle on ovarian reserve function applied before the laparoscopic cystectomy of ovarian endometriosis.Methods 106 patients with endometriosis treated from January 2015 to December 2015 in our hospital were selected.The subjects were divided into two groups according to the random number table, 53 cases of each group.The control group adopted the laparoscopic surgery;the observation group took the leuprorelin particle before the laparoscopic surgery.The operation condition, ovarian hormone and function were observed. Results The operation time and bleeding amount in observation group was better than control group ( P <0.05 ) .After surgery, the exhaust time between two groups had no significantly different.After surgery, the level of follicle stimulating hormone (FSH) in observation group was lower than control group; the level of estradiol (E2) in observation group was higher than control group (P <0.05); the level of luteinizing hormone (LH) between two groups had no significantly different.After surgery, the ovarian volume and antral follicle count ( AFC) in observation group was better than control group (P<0.05).Conclusion Before the laparoscopic cystectomy of ovarian endometriosis, the leuprorelin particle protects the ovarian function and morphology and has less impact in the level of hormone.

Objective To determine the role of C-reactive protein(CRP) in evaluating the activity of ulcerative colitis. Methods Analysis was used to estimate the correlation of CRP with mean platelet volume in 41 patients with active ulcerative colitis and 17 patients ulcerative colitis in re-mission. The effects on disease severity were analyzed subsequently. Results Active UC patients sera CRP level(8.58 ±2.43)mg/L,which level of severe UC CRP (14.38 ±4.46)mg/L,the moderate level of CRP UC(6.68 ±2.35)mg/L,mild level of CRP UC(4.94 ±1.21)mg/L, while the remission stage UC patients CRP levels(3.05 ±0. 88)mg/L. CRP was found to be significantly higher in sera of patients with active ulcerative colitis than that in patients in remission (P ＜ 0.05). The sera level of CRP in inflammatory bowel disease at severe stage were significantly higher than those of medium stage (P ＜ 0. 05). CRP was observed to be slightly increased in sera of patients at mild stage (P ＜ 0. 05). Conclusion The increase of CRP could reflect the severity of active ulcerative colitis.
