Objective: To compare the clinical outcomes of intracytoplasmic sperm injection (ICSI) between spermatozoa retrieved from testicular biopsy and from ejaculate in cryptozoospermia patients. Materials and Methods: The clinical data of 285 cryptozoospermia patients who underwent ICSI treatment in our center during the period from March 2009 to November 2013 were retrospectively analyzed. Within them, ejaculated sperms were used in 214 cases (group 1), and testicular sperms extracted by testicular sperm aspiration or conventional testis dissection sperm extraction were used in 71 cases (group 2). Good-quality embryo, fertilization, embryo implantation, pregnancy, and birth rates after ICSI were compared between the 2 groups. Results: Comparing the ejaculated sperm group with the testicular sperm group, fertilization rates were 59.6% and 60.6%, good-quality embryo rates were 36.8% and 46.1%, embryo implantation rates were 30.7% and 52.1%, pregnancy rates were 33.3% and 53.6%, and birth rates were 27.1% and 44.6%, respectively. Conclusion: Using testicular sperms can achieve higher rates of embryo implantation, pregnancy, and birth compared with those using ejaculated sperms for ICSI treatment in cryptozoospermia patients. © 2016.

To identify important prognostic factors and optimized treatment strategies through the analysis of the clinical and pathological characteristics of placental site trophoblastic tumor.108 patients with PSTT registered in two GTD centers or in six tertiary hospitals in China were analyzed retrospectively between the years 1998 and 2013. The computerized database of clinical and pathological reports was reviewed on this patient group. The data were subsequently analyzed retrospectively using SPSS software.Among 3581 patients with GTNs treated in GTD centers or in the tertiary hospitals between 1998 and 2013, 108 cases were histologically confirmed PSTT (3%). Only seven deaths and eleven relapse cases were observed. All seven of the deaths were disease related, due to chemotherapy-resistant or relapsed. 23 patients who received fertility preservation treatment did not experience poor outcome or high risk of relapse. In 71 patients with International Federation of Gynecology and Obstetrics (FIGO) stage I disease, the use of adjuvant chemotherapy following surgery (n=49) or not (n=22) made no significant difference in relapse rate (P=0.303) or survival (P=0.782). Univariate analysis revealed the interval between antecedent pregnancy and onset of PSTT, stage, prognosis score, and necrosis as significant predictors of poor survival but only stage remained significant on multivariate analysis.Patients with FIGO stage IV disease demonstrate the most critical risk indicator of PSTT in the current study. Preservation of fertility is considered in highly-selected patients with localized tumor; and surgery without chemotherapy is recommended as first line treatment for patients with stage I who are at low-risk.

Objective: To assess the 5' CpG island methylation of Fanconi anemia, complementation group F (FANCF) gene in epithelial ovarian cancer (EOC) tissues and normal ovarian tissues and to investigate the relationship between FANCF methylation and clinicopathologic features and prognosis of EOC. Methods: The experiment was performed with 112 EOC tissue samples (case group) and 60 normal ovarian tissues (control group). With methylation-specific polymerase chain reaction (MSP), FANCF methylation status of cases and controls was assessed. And the association between FANCF methylation and the clinicopathological features of EOC was investigated with univariate survival analysis and Cox regression model analysis. Results: The methylation-positive rate of the case group was significantly higher than that of the control group (P = 0.015). The FANCF promoter methylation rates showed significant differences in the comparisons stratified by age, International Federation of Gynecology and Obstetrics (FIGO) staging, histopathological classification, and lymph node metastasis (all P < .05). Univariate survival analysis showed there were significant differences in mean survival time between the groups based on FIGO staging, histopathological classification, lymph node metastasis, and FANCF methylation (all P < .05). Cox regression model analysis suggested that FIGO staging and FANCF methylation were independent risk factors for EOC prognosis. Conclusion: CpG island methylation of FANCF gene promoter region is strongly associated with the susceptibility and clinicopathologic features of EOC. The FIGO staging and FANCF methylation are independent risk factors for EOC prognosis. © The Author(s) 2015.

Purpose: Several studies have examined the association between glucokinase (GCK)-30G > A polymorphism and gestational diabetes mellitus (GDM). However, the results are still controversial. We performed the case–control study to investigate whether GCK-30G > A polymorphism correlates with the susceptibility of GDM in Chinese populations, and then conducted a meta-analysis by combining the previous studies. Methods: We recruited 948 GDM patients and 975 controls from May 2011 to August 2013. All the subjects were genotyped using the PCR-based invader assay. The differences of allelic frequencies and genotype distributions between GDM patients and controls were investigated in case–control study. A systematic search of all relevant studies was conducted. The observational studies that were related to an association between the glucokinase (GCK)-30G > A polymorphism and GDM were identified. The association between the glucokinase (GCK)-30G > A polymorphism and GDM susceptibility was assessed using genetic models. Results: The case–control study showed that GCK-30G > A polymorphism was associated with the susceptibility of GDM in a Chinese population. Furthermore, other six previously reported studies were included to perform meta-analysis. The meta-analysis showed that GCK-30G > A polymorphism was associated with GDM in Caucasian and Asian. Conclusions: This study suggested that GCK-30G > A polymorphism may be associated with the susceptibility of GDM in a Chinese population. The further meta-analysis provides additional evidence supporting the above result that the risk allele of the GCK-30G > A polymorphism may increase GDM risk. © 2015, Springer-Verlag Berlin Heidelberg.

Introduction The epidemiology of spinal cord injury without radiographic abnormality (SCIWORA) is less frequently reported in adults as compared with Children. The annual incidence of SCIWORA was approximately 5.74% per million in Tianjin from 2004 to 2008. Importantly, the epidemiological characteristics of adult SCIWORA may be different from that in Children. The aim of this study was to evaluate the radiological-clinical data of patients with adult SCIWORA, and to relatively analyze the epidemiological features. Materials and Methods Inpatients with cervical SCIWORA who were 16 and above in Tianjin were admitted in municipal hospitals in Tianjin from 2004 to 2008; all the patients received MRI scanning in sagittal and axial views. Epidemiological characteristics, such as injury origin, injury level or severity, neurological scale and MRI feature were acquired. Results In total, 203 patients were enrolled. The average age among the adult groups was 55.9 years (men 55.8 years, women 53.6 years). SCIWORA occurred more commonly in adults in the 46-60 age group, and falls were the leading cause of injury (52.2%), followed by vehicular injury (28.6%). The most predominantly affected level was C4/5 (48.7%), followed by C5/6 (30.5%) and C3/4 (12.8%), respectively. The occurrence of central cord syndrome (50.2%) with posterior longitudinal ligament tear (43.8%) was relatively higher than other injury patterns. Conclusion It is clear that adult cervical SCIWORA is different from that in the pediatric group. Our study highlights the epidemiological properties of adult SCIWORA in Tianjin, China. Differing from other reports, particularly epidemiology study, we represent the first report regarding adult SCIWORA from China. As the geriatric population increases, it is very important to set up an individualized evaluation system based on a nationally scaled epidemiological database. The results from our study will be useful in assisting in the creation of such a database. © 2011 Springer-Verlag.

Introduction: Podocytes can respond to various injuries, including mechanical stress secondary to diabetic nephropathy (DN), which may cause deleterious adhesive effects on podocytes. Integrin α3β1 is the major podocyte adhesion molecule. In this study, we aim to investigate α3β1 expression and identify differentially expressed microRNAs in podocytes under mechanical stress compared with normal cells and podocytes under mechanical stress treated with spironolactone, respectively. Materials and methods: Serum and glucocorticoid induced kinase 1 (SGK1), mineralocorticoid receptor (MR) and integrin α3β1 were detected by Western blotting. The miRNA analyses were performed by TaqMan MicroRNA Array v2.0. Genes Itga3 and Itgb1 were analyzed for miRNA binding sites within 3'UTRs using TargetScan and PicTar. Results: Protein SGK1 and MR expression were significantly increased under mechanical stress and decreased after spironolactone treatment. Podocyte α3 and β1 expression were significantly decreased under mechanical stress and increased after spironolactone treatment. MiR-124, miR-190, miR-217 and miR-188 were the overlapped miRNAs that were upregulated under mechanical stress and downregulated after spironolactone treatment. MiR-124 was found to be a predicted miRNA target site in both Itga3 and Itgb1 3'UTRs. Conclusion: These results provide a novel idea that miR-124 might play an important role in podocytic adhesion damage under mechanical stress. © The Author(s) 2012.

Human metastasis-associated gene 1 (MTA1) is highly associated with the metastasis of prostate cancer; however, the molecular functions of MTA1 that facilitate metastasis remain unclear. In this study, we demonstrate that the silencing of MTA1 by siRNA treatment results in the upregulation of E-cadherin expression by the phosphorylation of AKT (p-AKT) and decreases the invasiveness of prostate cancer cells. We show that MTA1 is expressed in over 90% of prostate cancer tissues, especially metastatic prostate cancer tissue, comparing to non-expression in normal prostate tissue. RT-PCR analysis and Western blot assay showed that MTA1 expression is significantly higher in highly metastatic prostate cancer PC-3M-1E8 cells (1E8) than in poorly metastatic prostate cancer PC-3M-2B4 cells (2B4). Silencing MTA1 expression by siRNA treatment in 1E8 cells increased the cellular malignant characters, including the cellular adhesive ability, decreased the cellular invasive ability and changed the polarity of cellular cytoskeleton. 1E8 cells over-expressing MTA1 had a reduced expression of E-cadherin, while 1E8 cells treated with MTA1 siRNA had a higher expression of E-cadherin. The expression of phosphorylated AKT (p-AKT) or the inhibition of p-AKT by wortmannin treatment (100 nM) significantly altered the function of MTA1 in the regulation of E-cadherin expression. Alterations in E-cadherin expression changed the role of p-AKT in cellular malignant characters. All of these results demonstrate that MTA1 plays an important role in controlling the malignant transformation of prostate cancer cells through the p-AKT/E-cadherin pathway. This study also provides a new mechanistic role for MTA1 in the regulation of prostate cancer metastasis. © 2012 Wang et al.

As a transforming growth factor-β (TGF-β)-inducible gene, the expression of Krüppel-like transcription factor 11 (KLF11) is altered in several types of cancer. In the current study, through using human 9K CpG island array, KLF11 was identified as one of hypermethylated genes in RAS-transformed ovarian T29H cells. Methylation of the KLF11 promoter was also observed in ovarian cancer tissue samples accompanied by significantly reduced KLF11 gene expression. Interestingly, the expression of SMAD2, SMAD3, and SMAD7 genes was reduced in the tumour, whilst no change was found in TGF-β expression. Our data suggest a relationship between promoter DNA methylation and KLF11 gene expression in ovarian cancer tumorigenesis. © 2015 Wiley Periodicals, Inc.

Quantifiably and located measure the methylation rate of 21 cytosine-phosphate-guanosine (CpG) sites in the 3' region of L1 gene and long control region (LCR) gene of HPV16 DNA in asymptomatic patients, cervical intraepithelial neoplasia (CIN) patients, and cervical cancer patients. To analysis the relationship between HPV16 methylation and it's pathogenicity. Chosen 30 cases with HPV16 positive in each group. Firstly, extract DNA from the remaining cells of liquid-based cytology specimen and bisulfite treatment DNA, then amplify the 3' region of L1 gene and LCR gene, test the methylation rate of 21 CpG sites of HPV16 DNA in three groups. All of the 5 CpG sites in E6/E7 promoter (31, 37, 43, 52, 58) were hypomethylation in cervical cancer group (21.86%, 28.15%, 21.37%, 26.15%, 15.48%, respectively), hypermethylation in asymptomatic group, and middle-methylation in CIN group, in which there were significant difference among three groups (all P < 0.01). The CpG site in 7032, 7091, 7136 of the 3' region of L1 gene was also different methylated among three groups (all P < 0.01). Hypermethylation was found in cancer group (18.89%, 27.72%), hypomethylation was found in asymptomatic group (2.71%, 6.95%) in 7032 and 7091. In 7136, the highest methylation was detected in CIN (66.45%), the lowest in asymptomatic (34.85%), middle in cancer group (46.43%). The methylation status of CpG sites in the 3' region of L1 gene and E6/E7 promoter of HPV16 is significant different among three groups, which is likely to anticipate the pathogenesis of CIN and cervical cancer.

The aim of our study was to assess the levels of human epididymis protein 4 (HE4) with the common tumor marker carbohydrate antigen 125 (CA125) in the diagnosis and monitoring of therapy for primary fallopian tube carcinoma (PFTC).Serum HE4 and CA125 levels from 82 PFTC patients and 154 patients with benign pelvic masses as the control were measured by Roche electrochemiluminescent immunoassay. HE4 determinations for surgery response and recurrence monitoring were assessed in PFTC patients.Serum HE4 and CA125 concentrations were significantly higher in PFTC patients compared with those seen in patients with benign pelvic masses (P < 0.001). Compared with CA125, HE4 had higher specificity, but lower sensitivity whether at early or advanced stage, and the combination of HE4 + CA125 led to higher sensitivity and specificity. HE4 + CA125 performed significantly better than CA125 or HE4 alone in early stage patients. In early stage the sensitivity was 35.7% for HE4 and 64.3% for CA125, while sensitivity for the combination of HE4 and CA125 could reach 71.4%. Furthermore, the two markers were associated with the progression and histology of PFTC. Serum HE4 level was closely correlated with surgical therapy. PFTC patients displayed a greater decline in the level of HE4 compared with CA125 (76.4% vs 55.7%). Combined with CA125, HE4 elevation better predicted recurrence in PFTC patients.This study indicated that serum HE4 levels are closely associated with PFTC and the outcome of surgical therapy and recurrence in Chinese patients.
