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 illustrate the evaluation effect of bivariate analysis of sensitivity and specificity meta-analysis model in diagnosis test to provide basis for selecting better evaluation method of diagnostic test.Methods Bivariate model was presented by reanalyzing the data from a published meta-analysis of two diagnostic techniques in diagnosis of schistosomiasis japonica.Results The bivariate model could directly provide summary estimates of(logit)sensitivity,specificity and DOR with corresponding 95% CI for two diagnostic tests(IHA and ELISA).Also,it could elicit any significant difference that existed among sensitivity,specificity and DOR between the two diagnostic methods,and incorporate any correlation that existed between sensitivity;specificity.Conclusion The bivariate model preserves the two dimensional nature of the original data,and separates effects of sensitivity and specificity,which is more rational than a net effect on diagnostic odds ratio scale as in SROC approach.The bivariate model is appropriate and agile,and can be used as an extension and improvement of the traditional SROC method.

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 investigate the changes of the serum levels of necrosis alpha (TNF-o)and interleukin 10( IL-10 )in patients with hypertensive renal damage,and to study the correlation of TNF-α and IL-10 with the hypertensive renal damage. Methods Seventy three patients with primary hypertension were divided into two groups according to their urinary albumin excretion rate(UAER): simple hypertensive group( n = 37 ),hypertensive renal damage group(n =36). TNF-α and IL-10 were measured using radioimmune assay. Thirty normotensive healthy persons were selected as normotensive control group. Results TNF-α were significantly higher and IL-10 significantly lower in patients with essential hypertension than those in normotensive control group(TNF-α: [2.91 ±0.94]μg/L vs [0.98 ±0.35]μg/L,P＜0. 05;IL-10:[ 19.2 ±5.8]μg/L vs [28.6±5. 7] μg/L,P ＜0. 01 ) ,and in patients with hypertension,those with renal damage had higher TNF-α and lower IL-10 than those without( TNF-α: [ 3.75 ± 0. 88 ] μg/L vs [ 1.87 ± 0. 58 ] μg/L, P ＜ 0. 01; IL-10: [ 15. 4 ± 4. 3 ]μg/L vs [ 22. 5 ± 5.9 ] μg/L, P ＜ 0. 01 ), with statistically significant difference between groups ( P ＜ 0. 01 ).TN F-α and IL- 10 were found to have correlations with UAER ( r = 0. 703, P ＜ 0. 001; r = - 0. 613, P ＜ 0. 001 ),but no correlation with the level of blood pressure. Conclusion TNF-α increased and IL-10 decreased significantly in patients with hypertensive renal damage, which indicates that the imbalanced cytokine network may play a role in the pathological mechanisms of hypertensive renal damage.
