Objective: To analyze the chemical constituents of the essential oil extracted from the seeds of Myristica fragrans Houtt.(nutmeg) in Indonesia and to provide qualities control scientific foundations.Methods: The essential oil was extracted by steam distillation and separated with GC capillary column.The relative content of every compound was determined by normalization method and the chemical compositions were evaluated by GC-MS.Results: Ninety-three chromatographic peaks were isolated and sixty-one compounds were identified,accounting for 97.62% of the total essential oil in nutmeg.Conclusion: The essential components of nutmeg in Indonesia is monoterpenoids and it's derivatives,accounting for 78.87% of the total essential oil.And phenolic compounds were the secondary composition,accounting for 16.79%.The essential oil contains safrole,which can induce genetoxicity and mutagenicity in animal,and myristicin and elemicin which can induce illusion.So,it must be careful when Myristica fragrans Houtt was used.

Objectives To study the expression patterns of steroid receptor coactivators (SRC) and steroid-induced stromal cell-derived factor-1 (SDF-1) in endometriosis,and to explore the roles of SRC in the steroid-induced SDF-1 expression endometriosis.Methods From May 2010 to October 2012,16 endometriosis cases at stages Ⅲ or Ⅳ according to the revised American Society for Reproductive Medicine classification undergoing surgery in the First Affiliated Hospital to Nanjing Medical University were enrolled in this study.Their ectopic endometrium were from ovarian endometriomata which were identified pathologically with 9 cases at proliferative phase and 7 cases at secretory phase.The normal endometrium were acquired from the healthy women with normal menstrual cycle (n =10,proliferative phase =5,secretory phase =5).The mnRNA levels of SRC and SDF-1α during the menstrual cycle were detected by quantitative real-time polymerase chain reaction.Ectopic endometrium stromal cells were purified and cultured in medium containing 17β-estradiol (10-8mol/L) or 17β-estradiol (10-8 mol/L) + progesterone (10-6 mol/L).At 24,48,72 and 96 hours,the supernatants were collected to measure SDF-1α expression by ELISA.Ectopic endometrium stromal cells were transfected respectively with siRNA of SRC-1 and SRC-2 using lipofectamine.Two days after transfection,17β-estradiol (10-8 moL/L) or 17β-estradiol (10-8 mol/L) + progesterone (10-6 mol/L) were added into the media.On the third day after the steroid hormones treatment,the media were collected to quantify SDF-1α expression with ELISA.Results (1) Cyclical changes: the SRC-1,SRC-2 and SDF-1 α showed marked cyclic differences in normal endometrium (P ＜ 0.05).In proliferative phase and secretory phase,the SRC-1,SRC-2 and SDF-1 α were 5.6 ± 1.2,3.8 ± 1.1,2.7 ± 0.5 and 2.6 ± 1.0,2.1 ± 1.0,1.6-± 0.5,respectively.There was no periodic variation in the expression of SRC-1,SRC-2 and SDF-1α in ectopic endometrium throughout the menstrual cycle.(2) Steroid-induced SDF-1α expression in ectopic endometrium stromal cells: the 17β-estradiol-induced SDF-1α expression was (1 803 ± 196),(2 272 ± 261) and (2 162 ± 258) ng/L at 48,72 and 96 hours.At the same time points,the SDF-1α expression induced by 17β-estradiol and progesterone was (1 307 ± 150),(1 518 ± 301) and (1 550 ± 144) ng/L,respectively.There was significant difference between two groups (P ＜0.05).(3) The effects of SRC silencing on steroid hormones-induced SDF-1 α expression in ectopic endometrium stromal cells: the expression of 17β-estradiol-induced SDF-1α at 72 hours was significantly decreased from (2 313 ± 357) ng/L to (1 155 ± 244) ng/L after the silencing of SRC-1 (P ＜ 0.05).After the silencing of SRC-2,the 17β-estradiol-induced SDF-1 α at 72 hours was (1 958 ±324) ng/L.There was no significant difference compared with the before the silencing (P ＞ 0.05).The expression of SDF-1 α at 72 hours induced by 17β-estradiol + progesterone was (1 534 ± 449) ng/L and (2 051 ± 380) ng/L respectively before and after the silencing of SRC-2 and showed the significant difference (P ＜ 0.05).Conclusion During the expression of SDF-1 α regulated by steroids in ectopic endometrium cells,SRC-1 is the major coactivator of 17β-estradiol and SRC-2 is the major coactivator of progesterone.

Abstract? AlM: To evaluate the meaning of using optical coherence tomography with enhanced depth imaging ( OCT-EDl ) to measure choroidal thickness of central serous retinopathy ( CSC) .?METHODS: With the retrospective case control study, 65 patients (65 eyes) with CSC and 50 healthy controls (50 eyes ) with age, gender and diopter - matched were recruited in this study. OCT-EDl were used to measure the subfoveal choroidal thickness ( SFCT ) in CSC eyes, the fellow eyes and also the control eyes. Of which 40 of the 65 CSC patients self-cured, 14 of them were treated with photodynamic therapy ( PDT ) , the left 11 accepted the laser photocoagulation ( LP ) . SFCT were measured 3mo after that. Compared with the previous data, the statistical analysis was carried out.?RESULTS: The SFCT value of 65 CSC eyes, 65 fellow eyes and 50 control eyes were 436. 23 ± 89. 50, 389. 45 ± 101. 03 and 329. 36 ± 95. 87μm, respectively. The SFCT of suffer and fellow eyes increased significantly compared to the control eyes ( P = 0. 008 and 0. 013, respectively). There was also significant difference in SFCT between the CSC eyes and the fellow eyes (P=0. 021). The SFCT were significantly decreased after PDT (P=0. 032), but with no significant changes after LP or self-cured ( P=0. 057 and 0. 076, respectively).?CONCLUSlON: OCT-EDl is a useful method to assess the choroidal topographic changes of CSC. The SFCT are significantly increased in the CSC eyes compared with that in the fellow eyes and the control eyes.
