Objective To analyse the clinical practicability and significance of fertility-sparing surgery for women with recurrent borderline ovarian tumors ( BOT).Methods The clinical and pathological recordings of 12 patients suffered from recurrent BOT in the Obstetrics and Gynecology Hospital of Fudan University from Jan.2002 to Dec.2012 were analyzed retrospectively.The menstruation situation , fertility function , recurrence rate and survival after second conservative surgery were collected and analyzed .Results The average onset age of these 12 patients was 26 years, and none of them had procreation before the second operation.The pathological diagnosis were still BOT and the recurrent sites of 10 patients were still restricted to the ovaries.Of the 12 cases, 8 cases of them had normal menstruation functions and 4 cases had less menstrual volumes or longer menstrual periods.Among 6 cases desired for pregnancy after the second operation,4 cases of them were successful.The spontaneous pregnancy rate was 4/6.The mean duration of follow-up was 53 months(range:23-97 months).All recurrent BOT, three cases developed recurrence once more,two cases of them were just be hinted by B ultrasounds and only one cases was approved to be BOT again by a once more surgical pathology.But no disease related deaths occurred.Conclusions The second fertility-sparing surgery may be feasible for women with recurrent BOT who are young and strongly desired for preservation of fertility.The spontaneous pregnancy rate is satisfactory.However, carefully follow-up is still needed.

Objective To explore the variation tendency of serum thyroid hormone level in the elderly aged over 80 years.Methods The 602 healthy volunteers were divided into 3 groups by age:young group (20-59 years of age,n= 226),elderly group (60-79 years of age,n= 195),and advanced age group (80-102 years of age,n=181).Fasting blood of all persons was harvested,then the levels of serum total triiodothyroxine (TT3),total thyroxine (TT4),free tri-iodothyronine (FT3),free thyroxine (FT4),thyroid-stimulating hormone (TSH) and reverse tri-iodothyronine (rT3) were determined by chemistry luminescence technique and radioimmunoassay.Statistical analysis was made by the software SPSS 13.0.Results The levels of serum FT3 and TT3 were lower in elderly group than in young group (t=2.793,3.627,P=0.005,0.000).There were significant differences in the levels of serum TT3,TT4,FT3,TSH and rT3 between young group and advanced-age group (t =10.930,6.065,15.398,- 2.933,- 5.643,all P = 0.000),also between elderly group and advanced-age group (t= 8.382,4.298,11.573,-3.383,-5.148,all P＜0.001).The levels of serum FT3,TT3 and TT4 were negatively correlated with age (r=- 0.51,-0.39 and -0.25,respectively,all P＜0.01).And the levels of serum rT3 and TSH showed positive relationships with age (r=0.32,0.12,all P＜0.01).There were no relationships between the level of serum FT4 and age.The positive rate of serum TT3,TT4,FT3,FT4,TSH and rT3 concentration beyond the reference value was 0,0,13.8%,0,6.6% and 21% in advanced-age group,respectively.Conclusions The levels of serum thyroid hormone and thyroid-stimulating hormone change with age.The levels of FT3,rT3 and TSH change obviously in the elderly aged over 80 years.It could reduce the false positive rate in clinical practice if normal reference range for serum thyroid hormone levels in different aged elderly is established.

Objective To observe effects of aqueous extractive of Clarke boea herb on mice with gastric ulcer, and provide basis for clinical application.Methods Gastric ulcer model was induced by reserpine. The mice were divided into normal group, model group, ranitidine group, low and high dose of Clarke boea herb groups. Mice in treatment groups were given corresponding drugs by gavage, and the normal group and control group were given the same amount of saline for 4 weeks. The area of gastric ulcer, serum proinflammatory cytokines gastric juice volume, gastric juice acidity, iNOS and COX-2 gene expressions were detected.Results Compared with control group, the gastric ulcer area in low and high dose of Clarke boea herb groups decreased significantly. Clarke boea herb increased the SS and VIP, decreased the MOT and SP serum levels (P<0.05,P<0.01). Clarke boea herb reduced the levels of serum proinflammatory cytokines of IL-6, IL-12, TNF-α and IFN-γ(P<0.05,P<0.01). Clarke boea herb also decreased the genetic expressions of iNOS and COX-2 (P<0.05,P<0.01).ConclusionClarke boea herb has good gastric ulcer preventive effects, and the high dose of Clarke boea herb group showed the best efficiency.

Objective To investigate the effects of silencing Smo gene on proliferation and apoptosis of rat prima-ry chondrocyte in vitro.Methods The primary chondrocyte was obtained by mechanical-enzyme digestion and identified by Immunohistochemical cells ( ColⅡ) .The animals were divided into control group , control siRNA group and Smo siRNA 1 ~3 group.The siRNA was transfected into chondrocytes by lentivirus vector .After 72 h, the cell viability was detected by MTT, Smo expression was detected by RT-PCR and Western blot, and the apoptosis of chondrocyte was assessed by flow cytometry .Results All types of siRNA were transfected into primary chondrocyte by vectors, the Smo siRNA 1 ~3 may inhibit the expression of Smo mRNA and protein in chondrocytes, and Smo siRNA2 had the highest silencing rate ( the expressions of Smo mRNA and protein were 0.19 ±0.03 and 0.39 ±0.07 ) .The cell viability in Smo siRNA2 group was lowest ( 77.38% ±7.19%) , while the apoptosis rate of Smo siRNA2 was highest ( 21.43%±2.97%) .Conclusions Silencing Smo gene in primary chondrocytes may inhibit proliferation and promote apoptosis , Smo may have a protecting role from apop-tosis of the chondrocyte.
