Objective To study the treatment effect of gonadotropin releasing hormone agonist?α( GnRH?α) different drug consolidation therapy time on endometriosis patients received endometriosis laparoscopic surgery?Methods Seventy cases endometriosis patients received endometriosis laparoscopic surgery in the People's Hospital of Meizhou from May 2012 to March 2014 were enrolled for study and randomly divided into 6 months group and 3 months group according to different time of GnRH?αtreatment?Then hormone levels, inflammatory mediators, follow?up condition and treatment outcome were compared between the two groups?Results The total effective rate of 6 months group was 97?14%( 34/35) ,significantly higher than that of 3 months group(80?00%(28/35)),the difference was significant(χ2 =5?081,P<0?05)?Serum follicle stimulating hormone( FSH) ,progesterone( LH) ,estradiol( E2) levels of 6 months group were significantly lower than 3 months group,the differences were significant((2?42±0?33) U/L vs?(3?79±0?42),(3?49±0?45) U/L vs?(5?12±0?60) U/L,(89?48±10?23) ng/L vs? (130?48±16?85) ng/L;t=15?174,12?858,12?305;P<0?05)?Serum TNF?α,IL?6,IL?8 levels of 6 months group were significantly lower than 3 months group,the differences were significant((18?48±2?23) ng/L vs?(31?49±4?05) ng/L,(14?45±2?18) ng/L vs?(23?49 ±2?95) ng/L,(35?29±4?52) ng/L vs? (58?49±7?28) ng/L;t=16?648,14?580,16?017;P<0?05)?The pregnancy rate,pain relief rate of 6 months group were significantly higher than 3 months group(51?43%(18/35) vs?22?86%(8/35),74?29%(26/35) vs?40?00%(14/35)),the recurrence rate was significantly lower than that 3 months group(8?57%(3/35) vs?31?43%(11/35)),the differences were significant(χ2=6?118, 8?400,5?714;P<0?05)?Conclusion 6 months GnRH?α treatment after laparoscopic surgery help to prevent disease relapse,and regulate hormone levels,inhibit inflammatory reaction,then improve the effect of treatment.

The 3T3-L1 preadipocytes were used as carriers in the investigation of total extract, n-butanol extract, CB-1 and CB-2 of Coreopsis tinctoria Nutt. on cell proliferation and differentiation. Three groups at different doses were set for each of the four extract regions of C. tinctoria Nutt., respectively. MTT assay was used to detect 3T3-L1cell proliferation by four extract regions of C. tinctoria Nutt. Oil Red O staining was used to analyze the formation and accumulation of cytoplasmic lipid during cell differentiation. The results showed that compared with the control group, there were significant inhibition on cell proliferation when thetotal extract of C. tinctoriaNutt. at 100 μg·mL-1, n-butanol extract at 0.5, 5, and 50 μg·mL-1, CB-1 and CB-2 at 50 μg·mL-1 (P< 0.01). N-butanol extract showed certain dose-dependent manner (r = -0.903). Oil Red O staining showed that compared with the control group, thetotal extract of C. tinctoria Nutt. at 1, 10, 100 μg·mL-1 can obviously inhibit cell differentiation, reduce the formation of cytoplasmic lipid (P< 0.01). N-butanol extract can inhibit cell differentiation in a dose-dependent manner (r= -0.779). CB-1 and CB-2 obviously inhibited cell differentiation at the concentration of 50 μg·mL-1 (P < 0.01). It was concluded that thetotal extract, n-butanol extract, CB-1 and CB-2 of C. tinctoria Nutt. can inhibit the proliferation and differentiation of 3T3-L1 preadipocytes and reduce the formation of cytoplasmic lipid.
