Abstract :
OBJECTIVE: To observe the effect of age and menstrual status on body composition in healthy Beijing women. METHODS: We measured body composition with dual-energy X-ray (GE Lunar Prodigy) in 316 healthy Beijing females aged 20 to 74 years (5-7 cases per age). Parameters provided by the software were as following: total body bone mineral content, lean mass, fat mass and fat percentage (%fat). Local regions measured included arm, leg, trunk, android region and gynoid region. Body mass index (BMI), fat mass index (FMI), free fat mass index (FFMI) and A/G were calculated. Volunteers were assigned to 6 groups according age by every ten years a group. RESULTS: BMC peaked during the 4th decade, LM peaked during the 5th decade, with a decline of 18.1% and 5.2% respectively at age 74 years. Total body fat mass and %fat showed a general increase with aging throughout the studied age range. Total body fat mass increased from 16+/-5 kg at age 20-29 years to 24+/-6 kg at age 70-74 years, while %fat increased from 31.3% to 39.5%. All local region %fat increased with aging at different extents. Android region %fat showed the largest raise extent (32.2%). BMI increased gradually from 21.1 kg/m2 at age 20-29 years to 26.1 kg/m2 at age 70-74 years. FMI changed more obviously than FFMI. A/G increased from 0.85 at age 20-29 years to 1.02 at age 70-74 years. Different menstrual status in women of 40-59 years had obvious effect on A/G and BMC (P<0.05), while it had no significant effect on BMI, body weight and waist circumference (P>0.05). CONCLUSIONS: Aging and menstrual status have evident effect on body composition distribution in healthy Beijing women.

Abstract :
OBJECTIVE: To study the presentation, histology type, stage of disease, treatment and outcome of epithelial ovarian malignancies in young women less than 30 years old. METHOD: A total of 21 cases of epithelial ovarian malignancies in young women less than 30 years old between Jan 1986 and Mar 2002 were analyzed retrospectively. RESULTS: The median age at the time of diagnosis was 24 years (range 16-29 years). All carcinomas occurred after menarche. The most common presenting symptoms were abdominal pain (50%), followed by tympanites (25%) and dysmenorrhea (19%), and the initial diagnosis was usually made based on physical examination, ultrasonography and serum CA(125). The mean maximal tumor diameter was 17.6 cm. Ten (67%) patients had stage I disease (5 Ia, 5 Ic), and 5 (33%) had stage III disease at the time of diagnosis; 43% were mucinous tumors, and 29% serous ones. Most tumors were well-differentiated ones classified as grade 1, 73%, others were grade 2, 13%, and grade 3, 13%. Optimal cytoreduction was achieved in 93% (14/15) of patients in primary treatment and 83% (5/6) in recurrence treatment. Eight patients were treated with conservative surgery, and 18 patients with chemotherapy, of which 7 patients had more than six courses of chemotherapy. The median follow-up was 50 months (range, 2-192 months). Six patients died in this series, 2 were alive with tumor, 11 alive free of tumor, and two were lost in follow-up. The 3-year and 5-year survival rate was 89%, and 76%, respectively. CONCLUSION: Young patients with epithelial ovarian carcinoma appear to have favorable stage and histologic grade and good survival.
