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 role of Janus kinase/signal transduction and transcriptional activation (JAK/STAT) pathway in rat liver damaged by excessive fluorine.Methods Thirty-six healthy Sprague-Dawley (SD) rats were randomized by weight and divided into three groups (6 males and 6 females per group):a control group (drunk water containing NaF ＜1 mg/L) and two fluorosis groups (drunk water containing NaF of 5 mg/L and 50 mg/ L).After 6 months of experiment treatment,the fluorine contents of urine and bone were detected by fluorine-ion electrode method.The rats liver function was determined by automatic blood chemical analyzer.The protein expression of Janus kinase (JAK1),signal transducer and activator of transcription (STAT3),B-cell lymphoma/ leukemia-2 (Bcl-2) and Bcl-associated x protein (Bax) were detected by immunohistochemistry (IHC) and protein imprinting (Western blotting).The activity of superoxide dismutase (SOD),glutathione peroxidase (GSH-PX) and the content of lipid peroxide (LPO) in liver tissue were determined with oxidative stress kit.Results The fluorine contents in the urine and bone in low-[(1.90 ± 0.12)mg/L,(210.37 ± 15.81)mg/kg] and high-dose [(2.20 ± 0.17)mg/L,(222.84 ± 10.21)mg/kg] fluoride groups were higher than those of control group [(1.74 ± 0.11)mg/L;(165.48 ± 10.37) mg/kg,F =33.840,69.149,P ＜0.05];the activity of serum alanine aminotransferase (ALT) and aspartate transaminase (AST) in high-dose fluorosis group [(69.83 ± 11.18),(167.56 ± 50.85) U/L] was higher than those of control group [(42.67 ± 7.07),(126.31 ± 16.76)U/L,F =32.135,4.984,all P ＜0.05];the protein expression of JAK1,STAT3 and Bax (1.56 ± 0.31,1.49 ± 0.49,1.41 ± 0.55) in high-dose fluorosis group were significantly higher than those of control group(1.01 ± 0.11,1.04 ± 0.15,0.87 ± 0.21,F=10.923,5.361,5.009,all P＜0.05),and Bcl-2 (0.61 ± 0.15) was significantly lower in high-dose fluorosis group than control group (1.04 ± 0.17,F =16.017,P ＜0.05);the activities of SOD and GSH-PX [(7.22 ± 0.88),(7.23 ± 2.47)U/mg prot] were significantly lower in high-dose fluorosis group than control group [(9.52 ± 1.51),(12.01 ± 5.16)U/mg prot,F =11.627,4.824,all P ＜0.05],and the contents of LPO [(9.23 ± 2.24)μmol/g prot] was significantly higher in high-dose fluorosis group than control group [(6.09 ± 1.55)μmol/g prot,F =7.457,P ＜0.05].Conclusion JAK/STAT signaling pathway and the oxidative stress,apoptosis may be the pathogenesis of liver damage in chronic fluorosis.

Objective To research the relationship between the gene polymorphism of serum amyloid A protein(SAA)1 and coronary heart disease(CHD).Methods By using PCR-RFLP and sequencing,the gene polymorphism of SAA1 of 183 patients with coronary heart disease and 152 healthy controls were analyzed.Result In the both groups 3 alleles(1.1,1.3,1.5)and 6 genotypes(1.1/1.1,1.1/1.5,1.1/1.3,1.3/1.3,1.3/1.5 and 1.5/1.5)were found.The frequency of 1.5 allele in healthy controls group was notably higher than that in CHD group(P

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.

The Hospital Survey on Patient Safety Culture (HSOPSC) questionnaire was used for appraisal in a newly-built general hospital for all the nursing staff, and they were provided with a six-month safety culture training according to appraisal results.The training has elevated the positive response rate of the nursing staff towards all dimensions of patient safety culture, proving that scientific and reasonable safety culture training is conducive to nurses' perception of patient safety culture.

Objective To observe the ultrasonographic features of local chest wall tumor recurrence after mastectomy for breast cancer and its clinical and histopathological characteristics. Methods The ultrasonographic features, clinical and histopathological characteristics of 27 patients with local chest wall tumor recurrence after mastectomy confirmed histopathologically were retrospectively reviewed. Results The disease-free intervals of twenty-seven patients ranged from 3 to 129 months [mean (31.9±31.4) months]. Most of the recurrence(18/27, 66.7%) occurred within 3 years after mastectomy. The clinical manifestations were:7 cases (7/27, 25.9%) with regional skin redness and swelling, red rash or ulceration on chest wall associated with or without palpable mass, 20 cases(20/27, 74.1%) with chest wall palpable masses without obvious skin change. On ultrasonography, 2 cases showed diffuse inifltrative type with ill-deifned inhomogeneous hypoechoic lesion and skin thickening. And twenty-ifve cases(43 lesions) showed mass type with a lesion size range of 5.4-114.7 mm [mean (24.4±21.6) mm]. Among them, 32 lesions were located near to the operation incision scar, 36 involved muscle layer, 38 were hypoechoic, 31 had irregular shape, 24 had indistinct margin, and 31 had blood lfow signal. In addition, calciifcation, halo, and taller-than-wide shape were absent in all 43 lesions. Conclusions The tumor recurrence often occurred within 3 years after mastectomy in high-risk patients. Ultrasonographic feature of chest wall recurrent lesion is of great value in the diagnosis.
