SOX6 plays important roles in cell proliferation, differentiation, and cell fate determination. It has been confirmed that SOX6 is a tumor suppressor and downregulated in various cancers, including esophageal squamous cell carcinoma, hepatocellular carcinoma, and chronic myeloid leukemia. Netrin-1 is highly expressed in various human cancers and acts as an anti-apoptotic and proangiogenic factor to drive tumorigenesis. The role of SOX6 and netrin-1 in regulating the growth of ovarian tumor cells still remains unclear. Real-time polymerase chain reaction and western blot were used to determine the SOX6 messenger RNA and protein levels, respectively, in ovarian cancer cells and tumor tissues. Stable transfection of SOX6 was conducted to overexpress SOX6 in PA-1 and SW626 cells. Cell viability was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Invasion of ovarian cancer cells and migration of human umbilical vein endothelial cells were confirmed by Transwell assays. To overexpress netrin-1, ovarian cancer cells with SOX6 restoration was transduced with netrin-1 lentiviral particles. PA-1 xenografts in a nude mice model were used to conduct in vivo evaluation of the role of SOX6 and its relationship with netrin-1 in tumor growth and angiogenesis. In this study, we found significantly reduced SOX6 levels in PA-1, SW626, SK-OV-3, and CaoV-3 ovarian cancer cell lines and human tumor tissues in comparison with normal human ovarian epithelial cells or matched non-tumor tissues. SOX6 overexpression by stable transfection dramatically inhibited proliferation and invasion of PA-1 and SW626 cells. Also, conditioned medium from PA-1 and SW626 cells with SOX6 restoration exhibited reduced ability to induce human umbilical vein endothelial cells migration and tube formation compared with conditioned medium from the cells with transfection control. Furthermore, an inverse relationship between SOX6 and netrin-1 expression was observed in PA-1 and SW626 cells. Overexpression of netrin-1 in ovarian cancer cells with forced SOX6 expression remarkably abrogated the inhibitory effect of SOX6 on proliferation, invasion of the cells, and tumor xenograft growth and vascularity in vivo. Human umbilical vein endothelial cell migration and tube formation were enhanced in the conditioned medium from the ovarian cancer cells transduced with netrin-1 lentivirus particles. Our observations revealed that SOX6 is a tumor suppressor in ovarian cancer cells, and SOX6 exerts an inhibitory effect on the proliferation, invasion, and tumor cell-induced angiogenesis of ovarian cancer cells, whereas nerin-1 plays an opposite role and its expression is inversely correlated with SOX6. Moreover, our findings suggest a new role of SOX6 and netrin-1 for understanding the progression of ovarian cancer and have the potential for the development of new diagnosis and treatment strategies for ovarian cancer. © The Author(s) 2017.

The aim of this meta-analysis was to evaluate the diagnostic value of 3D time-of-flight magnetic resonance angiography (3D-TOF-MRA) in trigeminal neuralgia (TN). Relevant studies were identified by computerized database searches supplemented by manual search strategies. The studies were included in accordance with stringent inclusion and exclusion criteria. Following a multistep screening process, high quality studies related to the diagnostic value of 3D-TOF-MRA in TN were selected for meta-analysis. Statistical analyses were conducted using Statistical Analysis Software (version 8.2; SAS Institute, Cary, NC, USA) and Meta Disc (version 1.4; Unit of Clinical Biostatistics, Ramon y Cajal Hospital, Madrid, Spain). For the present meta-analysis, we initially retrieved 95 studies from database searches. A total of 13 studies were eventually enrolled containing a combined total of 1084 TN patients. The meta-analysis results demonstrated that the sensitivity and specificity of the diagnostic value of 3D-TOF-MRA in TN were 95% (95% confidence interval [CI] 0.93-0.96) and 77% (95% CI 0.66-0.86), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 2.72 (95% CI 1.81-4.09) and 0.08 (95% CI 0.06-0.12), respectively. The pooled diagnostic odds ratio of 3D-TOF-MRA in TN was 52.92 (95% CI 26.39-106.11), and the corresponding area under the curve in the summary receiver operating characteristic curve based on the 3D-TOF-MRA diagnostic image of observers was 0.9695 (standard error 0.0165). Our results suggest that 3D-TOF-MRA has excellent sensitivity and specificity as a diagnostic tool for TN, and that it can accurately identify neurovascular compression in TN patients.

Purpose: The aim of this study is to identify the association between miR-34's family and the prognosis of HB in a large Asian cohort and to explore the interaction of miR-34 with other independent risk factors in the process of affecting prognosis of HB. Methods: We retrospectively reviewed 78 children with HB (36 female, 42 male) managed in our institutions between 2007 and 2014. The expression of miR-34 was detected by real-time PCR. Prognostic factors were evaluated using Kaplan-Meier curves and Cox proportional hazards models. Results: For the entire cohort of 76 patients, The normalized real-time PCR results showed that all three miRNAs were deregulated in tumor tissues as compared with corresponding noncancerous tissue samples. Descriptive survival statistics and Kaplan-Meier curves suggested that AFP levels, metastases, vascular invasion, PRETEXT stage and miR-34 had prognostic significance in this relatively selected cohort. After that we made miR-34 into different combinations. The results demonstrated that combined low miR-34a and miR-34b (HR:2.212, P = 0.016), combined low miR-34a and miR-34c (HR:1.984, P = 0.025) and combined low miR-34a, miR-34b and miR-34c (HR:3.569, P = 0.001) were independent prognostic factors of HB. We further conduct stratified analysis of the impact of other identified risk factors on the combined low of three miR-34. Conclusions: In this study, we found that miR-34s were deregulated in tumor tissues compared with corresponding noncancerous tissue samples. We also confirmed that combined low miR-34 is an independent prognostic factor related with HB. © 2016 Elsevier Inc.

It is estimated that at least 30% of the population has some degree of vertebral disc degeneration by the time they reach 40 years of age, and a finding of disc degeneration is often considered normal in patients over the age of 60. Despite the frequency at which disc degeneration occurs and its often painful and debilitating consequences, the exact cause of disc degeneration remains unclear. To investigate the relationship between the exon 19 polymorphism of the COL9A2 gene and lumbar disc degeneration in a Chinese population, 239 patients were enrolled in this study: 119 patients with lumbar disc degeneration and 120 without intervertebral disc disease. All study participants were patients in our hospital between July 2013 and May 2015. Genomic DNA was isolated from all subjects, and COL9A2 genotypes were determined by polymerase chain reaction (PCR) and direct DNA sequencing in a case-control study. Statistical analysis was performed using a chi-square test and Fisher’s exact test. Gln326 replacement with Trp was observed in 6 patients in the case group and 13 patients in the control group. The difference in the prevalence of Gln326 replacement to Trp between the case group and the control group was not statistically significant (P > 0.05). Gln326 replacement with Arg was observed in 72 patients in the case group and 64 patients in the control group. The difference in the prevalence of Gln326 replacement to Arg between the case group and the control group was not statistically significant (P > 0.05). MRI analysis of patients with lumbar disc degeneration showed no association between Arg326, Gln326, or Trp326 and the location of disc degeneration or the number of degenerated segments (both P > 0.05). In brief, the data do not support an association between exon 19 polymorphism of the COL9A2 gene and lumbar disc degeneration in this Han Chinese population. © 2016, E-Century Publishing Corporation.

Objective To explore the clinical application and curative effect of iron removal treatment with week-therapy in chronic iron overload related to blood transfusion. Methods Twenty patients who were diagnosed as chronic iron overload were retrospectively studied. The amelioration of liver and pancreatic fanctions in patients with chronic iron overload treated with week-therapy of iron chelating agent through intravenous drip. Results The changes in the level of serum ferritin [2693.7±709.9)μg/L] were not significant after treatment at six months, but the cilinical symptoms were relieved obviously. The levels of serum ferritin in patients after the treatment at twelve months were significantly different from the level before treated [(2083.7±714.4)μg/L vs (2771.5±725.2)μg/L, t = 3.35, P < 0.01], and the decreases were significant in sixteen patients. The liver functions in seven patients were improved and pancreatic functions were better in five patients. Conclusion The study suggests that iron removal treatment with week-therapy is effective for chronic iron overload, and improves the functions of damaged organs.

Purpose: To investigate the curative effect of poly-DL-lactic acid (PDLLA) absorbable screw as a locked intramedullary nail for simple tibia fractures. Methods: In this study, 35 patients treated with the PDLLA screw were observed, and another 35 patients treated with a traditional locking intramedullary nail were treated as controls. Intraoperative blood loss, postoperative complications, fracture-healing time, and Johner-Wruh grade at the last followup time point of the two treatment groups were compared. Results: No patients experienced neurovascular injury during the operation, and no significant difference was observed in the operation and intraoperative blood loss of both two groups (p > 0.05). Postoperative x-ray results showed that the counterpoint and alignment of the fractures were favorable and that no rotational displacement had occurred. The follow-up period for all patients was 6 - 24 months, with a mean of 15.6 ± 6.7 months. All patients treated with PDLLA screw were observed to have well-healed tibia fractures, while three patients in the traditional treatment group appeared to have undesirable fracture healing. No infection, breakage of the internal fixator, or rotational displacement was found in either of the two groups, and no significant difference was observed in complication incidence between the two groups (p > 0.05). Additionally, Johner-Wruh grading showed no statistically significant difference between the two groups (p > 0.05). Interestingly, the fracture-healing time of the PDLLA screw-treated patients was significantly shortened compared with that of traditional treatment patients (p < 0.05). Conclusion: PDLLA screw, as a locked intramedullary nail, is a promising treatment for simple tibia fractures. © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria.

Diabetic retinopathy (DR), a major complication of diabetes mellitus, is the leading cause of adult blindness. The Toll-like receptor (TLR) family is believed to be involved in the pathogenesis and progression of DR. Here, we investigated the expression profiles of TLR-2 and TLR-4 in retinal ganglion cells (RGCs), in an attempt to elucidate the role of these molecules in the etiology of DR. In vitro cultured RGCs were divided into control and high-glucose groups. The mRNA and protein levels of TLR-2, TLR-4, and nuclear factor (NF)-κB were detected by real-time PCR and western blotting. RGCs were further transfected with specific siRNA targeting TLR2/TLR4; the proliferation of transfected RGCs and their tumor necrosis factor (TNF)-α and interleukin (IL)-8 secretory capacity were analyzed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and enzyme-linked immunosorbent assays (ELISA), respectively. In a high-glucose environment, TLR-2/4 expression was significantly upregulated in RGCs (while their viability decreased); additionally, NF-κB expression and secretion of TNF-α and IL-8 were significantly increased. Co-silencing of the TLR-2 and TLR-4 genes inhibited NF- κB expression and TNF-α/IL-8 secretion, while increasing the survival rate of RGCs. Therefore, a high-glucose environment can potentiate the expression of TLR-2 and TLR-4 in RGCs, activate the downstream signaling pathway, and increase the secretion of pro-inflammatory factors, thereby aggravating DR. © FUNPEC-RP.

Preeclampsia (PE) is a disorder of pregnancy marked by hypertension and proteinuria with no known treatment aside from pregnancy termination. The pathogenesis of PE is poorly understood, but is thought to originate in the placenta. We assessed the value of measuring serum and urinary soluble deformylase-like tyrosine kinase receptor 1 (sFlt-1), a known target of placental factors, and placental growth factor (PLGF), a key placental signaling molecule, in the diagnosis of PE.Eighty patients with PE were classified as either exhibiting mild (44 cases) or severe (36 cases) symptoms of PE. Forty normal pregnant women were selected as controls. Serum and urinary PLGF and sFlt-1 levels, along with the ratio of sFlt-1 to PLGF, were compared across groups.Serum and urinary sFlt-1 and sFlt-1/PLGF ratios in severe PE patients were significantly higher than those in the mild PE group, and measurements from mild PE patients were significantly higher than controls (all P values <0.01). The serum and urinary PLGF levels in severe PE patients were significantly lower than mild PE patients, and mild PE patients had significantly lower PLGF levels than controls (all P values <0.01). As expected, serum sFlt-1 and PLGF levels and ratios were highly correlated with urinary sFlt-1 and PLGF levels and ratios.The severity of PE was closely correlated with these measurements, suggesting that they may be useful tools in the diagnosis and evaluation of PE.
