Abstract
Limited information on oocytes and fertilization prevents the efficient therapy of patients with infertility. The most important reason for this lack of understanding is a deficiency in research dedicated to oocytes and fertilization. Currently, we are concerned with the role of nutrition in the process of oocyte development to better understand the relationship between nutrition and infertility. The aim of this study was to explore the relationship between some exceptional materials and infertility to elucidate the role of these materials in oocyte development. We used proteomic analysis to identify numerous nutrition-related proteins in three developmental stages: the germinal vesicle stage, the metaphase II-arrested stage, and the fertilized oocyte-zygote stage. Specific proteins were abundantly expressed during the three stages. These proteins included astacin-like metalloendopeptidase, selenium-binding proteins, and other proteins involved in metabolic and signaling pathways. Other proteins were involved in the citrate cycle, the electron transport chain, the urea cycle, fatty acid metabolism, and the insulin signaling pathway. Almost all these proteins exhibited different expression levels in the three stages. The results of the present study provide a better understanding of the molecular mechanisms of early embryonic development and suggest new treatment methods for infertility.

Abstract
β-amyloid peptides (Aβs) can exert neurotoxic effects through induction of oxidative damage, whereas lipoic acid (LA), a powerful antioxidant, can alleviate oxidative damage. In this study, we explored the effect and mechanism of action of LA on beta-amyloid-intoxicated C6 glioma cells. Cells were randomly divided into three groups: control (vehicle), Aβ, and LA + Aβ. The LA + Aβ group was treated with LA for 2 h, then both the Aβ-only and the LA + Aβ groups were incubated with 25 μM Aβ for 24 h. Cell viability was measured by the MTT method. Mitochondrial reduced glutathione (GSH) and oxidized glutathione (GSSG) levels were detected by enzyme-linked immunosorbent assay (ELISA), and the GSH to GSSG ratio calculated. Real-time polymerase chain reaction and western blot analyses were used to detect MnSOD mRNA and protein, respectively. Aβ significantly inhibited C6 cell proliferation compared with the control group (P < 0.05). LA markedly increased cell viability compared with the Aβ group (P < 0.05). The increased GSSH and decreased GSH mitochondrial accumulation induced by Aβ was profoundly reversed by treatment with LA (P < 0.05). Aβ significantly reduced MnSOD expression compared to controls (P < 0.05), whereas LA pretreatment increased MnSOD expression compared with the Aβ-only group (P < 0.05); MnSOD protein levels showed similar patterns. These results suggest that LA might protect Aβ-intoxicated C6 glioma cells by alleviating oxidative damage, providing a new treatment strategy for neurodegenerative diseases.

Abstract
INTRODUCTION The aim of this meta-analysis was to further explore whether the relapse, 5-year survival and metastasis the same or not between limb-salvage and amputation in the treatment of patients with limited stage Enneking II pathologic fracture osteosarcoma. MATERIALS AND METHODS An electronic search of the Medline, EMBASE and CNKI was done on October 2014. The clinical studies about amputation or limb-salvage surgery in the treatment of patients with limited stage Enneking II pathologic fracture osteosarcoma were searched and reviewed. The effect size of relapse, 5-year survival and metastasis between the amputation and limb-salvage surgery were pooled by stata11.0 software (Stata Corporation, College Station, TX, USA, http://www.stata.com;) using random or fixed effect model. The funnel plot and Egger's line regression test were used for evaluation of publication bias. RESULTS A total of 89 studies were identified and seven articles with 200 cases in the limb-salvage surgery group and 84 subjects in the amputation group were finally included in the meta-analysis. The pooled data indicated that no statistical different of risk for developing relapse between limb-salvage and amputation was found relative risk (RR) =1.40, 95% confidence interval (CI): 0.71-2.79, (P = 0.33). The 5-year survival rate of patients underwent limb-salvage surgery was smaller than patients received amputation RR = 1.86, 95%CI: 1.19-2.89, (P = 0.01); the metastasis rate of patients underwent limb-salvage surgery was significant decreased compared with patients received amputation RR = 0.56, 95% CI: 0.34-0.94, (P = 0.03). No publication bias was existed in this meta-analysis. CONCLUSION Limb-salvage surgery does not increased the risk of relapse compared with amputation in the treatment of patients with limited stage Enneking II pathologic fracture osteosarcoma.

Abstract
BACKGROUND Veliparib (ABT-888) is a potent, orally bioavailable, small-molecule inhibitor of the DNA repair enzymes poly ADP-ribose polymerase-1 and -2. Veliparib enhances the efficacy of temozolomide (TMZ) and other cytotoxic agents in preclinical tumor models. PATIENTS AND METHODS In this multicenter, double-blind trial, adults with unresectable stage III or IV metastatic melanoma were randomized 1:1:1 to TMZ plus veliparib 20 or 40 mg, or placebo twice daily. Efficacy end points included progression-free survival (PFS), overall survival (OS), and objective response rate (ORR). RESULTS Patients (N = 346) were randomized between February 2009 and January 2010. Median [95% confidence interval (CI)] PFS was 3.7 (3.0-5.5), 3.6 (1.9-4.1), and 2 (1.9-3.7) months in the 20-mg, 40-mg, and placebo arms, respectively. Median (95% CI) OS was 10.8 (9.0-13.1), 13.6 (11.4-15.9), and 12.9 (9.8-14.3) months, respectively; ORR was 10.3%, 8.7%, and 7.0%. Exploratory analyses showed patients with low ERCC1 expression had longer PFS when TMZ was combined with veliparib. Toxicities were as expected for TMZ. The frequencies of thrombocytopenia, neutropenia, and leukopenia were significantly increased in the veliparib groups. Grade 3 or 4 adverse events, mainly hematologic toxicities, were seen in 55%, 63%, and 41% of patients in the 20-mg, 40-mg, and placebo arms, respectively. CONCLUSIONS Median PFS with 20 and 40 mg veliparib almost doubled numerically compared with placebo, but the improvements did not reach statistical significance. OS was not increased with veliparib. Toxicities were similar to TMZ monotherapy, but with increased frequency.

Abstract
Disturbed cell autophagy is found in various cardiovascular disease conditions. Biomechanical stimuli induced by laminar blood flow have important protective actions against the development of various vascular diseases. However, the impacts and underlying mechanisms of shear stress on the autophagic process in vascular endothelial cells (ECs) are not entirely understood. Here we investigated the impacts of shear stress on autophagy in human vascular ECs. We found that shear stress induced by laminar flow, but not that by oscillatory or low-magnitude flow, promoted autophagy. Time-course analysis and flow cessation experiments confirmed that this effect was not a transient adaptive stress response but appeared to be a sustained physiological action. Flow had no effect on the mammalian target of rapamycin-ULK pathway, whereas it significantly upregulated Sirt1 expression. Inhibition of Sirt1 blunted shear stress-induced autophagy. Overexpression of wild-type Sirt1, but not the deacetylase-dead mutant, was sufficient to induce autophagy in ECs. Using both of gain- and loss-of-function experiments, we showed that Sirt1-dependent activation of FoxO1 was critical in mediating shear stress-induced autophagy. Shear stress also induced deacetylation of Atg5 and Atg7. Moreover, shear stress-induced Sirt1 expression and autophagy were redox dependent, whereas Sirt1 might act as a redox-sensitive transducer mediating reactive oxygen species-elicited autophagy. Functionally, we demonstrated that flow-conditioned cells are more resistant to oxidant-induced cell injury, and this cytoprotective effect was abolished after inhibition of autophagy. In summary, these results suggest that Sirt1-mediated autophagy in ECs may be a novel mechanism by which laminar flow produces its vascular-protective actions.

Abstract
BACKGROUND Interleukin (IL)-6, an important proinflammatory cytokine, plays a potential pathological role in systemic lupus erythematosus (SLE). Studies on the relationship of IL-6 gene polymorphisms with SLE are inconclusive. The aim of this study was to estimate the relationship more precisely. METHODS The databases of PubMed and Web of Science updated to 30 August 2014 were retrieved. Meta-analysis was conducted using allelic contrast, dominant, recessive and homozygote contrast models. Fifteen studies were included in this study and ethnicity-specific meta-analysis was performed on European, Iranian and Asian populations. RESULTS Analysis for the IL-6-174 G/C polymorphism under all models except the homozygote contrast model indicated an association in the overall population (allelic contrast model: odds ratio (OR) 1.428, 95% confidence interval (CI) 1.124-1.812, dominant model: OR 1.382, 95% CI 1.037-1.842, recessive model: OR 1.610, 95% CI 1.158-2.240, homozygote contrast model: OR 1.759, 95% CI 0.989-3.127), as well as in European individuals under all four genetic models (allelic contrast model: OR 1.557, 95% CI 1.155-2.098, dominant model: OR 1.699, 95% CI 1.203-2.400, recessive model: OR 1.506, 95% CI 1.176-1.930, homozygote contrast model: OR 2.118, 95% CI 1.103-4.065). Analysis for the IL-6-572 G/C polymorphism indicated significant association in overall ethnicities under the recessive model (OR 1.491, 95% CI 1.104-2.014), but not under other models or in Asian individuals. In addition, significant association between the IL-6-174 G/C polymorphism and discoid skin lesions and antinuclear antibodies (ANAs) were found under the allelic contrast model and recessive model, respectively (discoid skin lesions: OR 2.271, 95% CI 1.053-4.895; ANAs: OR 2.244, 95% CI 1.141-4.416). CONCLUSION This meta-analysis provides evidence of the association between the IL-6 polymorphism and the risk of SLE, hinting that the IL-6-174 G/C and IL-6-572 G/C polymorphisms may play a role in SLE susceptibility.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2015; 45:530-8.

Abstract
OBJECTIVES To report the clinical performance of massively parallel sequencing-based non-invasive prenatal testing (NIPT) in detecting trisomies 21, 18 and 13 in over 140,000 clinical samples and to compare its performance in low-risk and high-risk pregnancies. METHODS Between 1 January 2012 and 31 August 2013, 147,314 NIPT requests to screen for fetal trisomies 21, 18 and 13 using low-coverage whole-genome sequencing of plasma cell-free DNA were received. The results were validated by karyotyping or follow-up of clinical outcomes. RESULTS NIPT was performed and results obtained in 146,958 samples, for which outcome data were available in 112,669 (76.7%). Repeat blood sampling was required in 3213 cases and 145 had test failure. Aneuploidy was confirmed in 720/781 cases positive for trisomy 21, 167/218 cases positive for trisomy 18 and 22/67 cases positive for trisomy 13 on NIPT. Nine false negatives were identified, including six cases of trisomy 21 and three of trisomy 18. The overall sensitivity of NIPT was 99.17%, 98.24% and 100% for trisomies 21, 18 and 13, respectively, and specificity was 99.95%, 99.95% and 99.96% for trisomies 21, 18 and 13, respectively. There was no significant difference in test performance between the 72,382 high-risk and 40,287 low-risk subjects (sensitivity, 99.21% vs. 98.97% (P = 0.82); specificity, 99.95% vs. 99.95% (P = 0.98)). The major factors contributing to false-positive and false-negative NIPT results were maternal copy number variant and fetal/placental mosaicism, but fetal fraction had no effect. CONCLUSIONS Using a stringent protocol, the good performance of NIPT shown by early validation studies can be maintained in large clinical samples. This technique can provide equally high sensitivity and specificity in screening for trisomy 21 in a low-risk, as compared to high-risk, population.

Abstract
Hormesis is an adaptive response to a variety of oxidative stresses that renders
cells resistant to harmful doses of stressing agents. Caffeic acid (CaA) is an
important antioxidant that has protective effects against DNA damage caused by
reactive oxygen species (ROS). However, whether CaA-induced protection is a hormetic
effect remains unknown, as is the molecular mechanism that is involved. We found that
a low concentration (10 μM) of CaA increased human liver L-02 cell viability,
attenuated hydrogen peroxide (H2O2)-mediated decreases in cell
viability, and decreased the extent of H2O2-induced DNA
double-strand breaks (DSBs). In L-02 cells exposed to H2O2, CaA
treatment reduced ROS levels, which might have played a protective role. CaA also
activated the extracellular signal-regulated kinase (ERK) signal pathway in a
time-dependent manner. Inhibition of ERK by its inhibitor U0126 or by its specific
small interfering RNA (siRNA) blocked the CaA-induced improvement in cell viability
and the protective effects against H2O2-mediated DNA damage.
This study adds to the understanding of the antioxidant effects of CaA by identifying
a novel molecular mechanism of enhanced cell viability and protection against DNA
damage.

Abstract
Field measurements were simultaneously conducted at a mountain (Mt.) site (Tai Mao Shan, TMS) and an urban site (Tsuen Wan, TW) at the foot of the Mt. TMS in Hong Kong. An interesting event with consecutive high-ozone (O₃) days from 08:00 on 28 Oct. to 23:00 on 03 Nov., 2010 was observed at Mt. TMS, while no such polluted event was found at the foot of the mountain. The Weather Research and Forecasting (WRF)-Community Multiscale Air Quality (CMAQ) models were used to understand this event. Model performance evaluation showed that the simulated meteorological parameters and air pollutants were well in agreement with the observations. The index of agreement (IOA) of temperature, relative humidity, wind direction and wind speed were 0.93, 0.83, 0.46 and 0.60, respectively. The multi-day high O₃ episode at Mt. TMS was also reasonably reproduced (IOA=0.68). Horizontally, the photochemical processes determined the O₃ levels in southwestern Pearl River Delta (PRD) and the Pearl River Estuary (PRE), while in eastern and northern PRD, the O₃ destruction was over the production during the event. Vertically, higher O₃ values at higher levels were found at both Mt. TMS and TW, indicating a vertical O₃ gradient over Hong Kong. With the aid of the process analysis module, we found positive contribution of vertical transport including advection and diffusion to O₃ mixing ratios at the two sites, suggesting that O₃ values at lower locations could be affected by O₃ at higher locations via vertical advection and diffusion over Hong Kong.

Abstract
AIM To test the association of PLA2G6 variants with Type 2 diabetes and clinical characteristics in large Chinese population-based samples. METHODS A total of 6822 people were recruited. In the first stage, 15 single nucleotide polymorphisms within the PLA2G6 region were selected and genotyped in 3700 Chinese Han people. In the second stage, the single nucleotide polymorphisms that showed a significant association were genotyped in an additional 3122 samples for replication. Genotype-phenotype association studies and meta-analyses were performed after combining data from the two stages. RESULTS In the first stage, we detected rs132984 and rs2284060 as significantly associated with Type 2 diabetes with odds ratios of 1.247 (95% CI 1.074-1.449, P = 0.004, empirical P = 0.047) and 1.173 (95% CI 1.059-1.299, P = 0.002, empirical P = 0.029), respectively. In the second stage, a similar effect of rs132984 on Type 2 diabetes was observed (odds ratio 1.280, 95% CI 1.094-1.497, P = 0.002). The meta-analysis showed a significant effect of the two single nucleotide polymorphisms on Type 2 diabetes (odds ratio 1.254, 95% CI 1.104-1.451, P = 4.85 × 10⁻⁵ for rs132984; odds ratio 1.120, 95% CI 1.046-1.195, P = 0.003 for rs2284060). Moreover, genotype-phenotype association analysis showed that rs132984 was associated with triglyceride levels (P = 0.022, empirical P = 0.044) and area under the curve for glucose (P = 0.015, empirical P = 0.030). CONCLUSIONS Our data imply that common single nucleotide polymorphisms within the PLA2G6 region are associated with Type 2 diabetes and triglyceride levels in the Chinese population.

Abstract
Several species of the genus Cryptolestes Ganglbauer, 1899 (Coleoptera: Laemophloeidae) are commonly found in stored products. In this study, five species of Cryptolestes, with almost worldwide distribution, were obtained from laboratories in China, Czech Republic and the USA: Cryptolestes ferrugineus (Stephens, 1831), Cryptolestes pusillus (Schönherr, 1817), Cryptolestes turcicus (Grouvelle, 1876), Cryptolestes pusilloides (Steel & Howe, 1952) and Cryptolestes capensis (Waltl, 1834). Molecular identification based on a 658 bp fragment from the mitochondrial DNA cytochrome c oxidase subunit I (COI) was adopted to overcome some problems of morphological identification of Cryptolestes species. The utility of COI sequences as DNA barcodes in discriminating the five Cryptolestes species was evaluated on adults and larvae by analysing Kimura 2-parameter distances, phylogenetic tree and haplotype networks. The results showed that molecular approaches based on DNA barcodes were able to accurately identify these species. This is the first study using DNA barcoding to identify Cryptolestes species and the gathered DNA sequences will complement the biological barcode database.

Abstract
BACKGROUND Short sleep duration has recently been found to be associated with obesity in children, but findings involving adolescents have been less consistent, and some have mentioned gender differences. OBJECTIVES To investigate the association between parent-reported sleep duration and adiposity in early adolescence (10-12 years old) and to explore gender differences within this population. METHODS Participants were 1309 fifth-grade students (685 boys) from 10 primary schools in Shanghai, China. Body mass index (BMI), waist-height ratio (WHeR) and body fat percentage (BF%) were assessed. Sleep and other potential contributors were recorded by parents or self-reported. RESULTS Compared with adolescents in the longest sleep group (greater than or equal to +1 SD, ≥10.05 h), those in the shortest sleep group (less than -1 SD, <8.89 h) had significantly higher BMI, WHeR and BF%. Sleep was found to be closely related to increased adiposity in girls who were in the shortest and shorter sleep group (<mean, <9.45 h). No association was found in boys. CONCLUSIONS Short sleep duration was associated with higher adiposity indices in early adolescents from China, especially in girls. Interventions focusing on modifying adolescents' sleep habits may potentially prevent obesity and overweight.

Abstract
OBJECTIVES To evaluate the performance of a massively parallel sequencing (MPS)-based test in detecting fetal sex chromosome aneuploidy (SCA) and to present a comprehensive clinical counseling protocol for SCA-positive patients. METHODS This was a retrospective study in a large patient cohort of 5950 singleton pregnancies which underwent MPS-based testing as a prenatal screening test for trisomies 21, 18 and 13, with X and Y chromosomes as secondary findings, in Southwest Hospital in China. MPS-based SCA-positive women were offered the choice of knowing whether their SCA results were positive and those who did commenced a two-stage post-test clinical counseling protocol. In Stage 1, general information about SCA was given, and women were given the option of invasive testing for confirmation of findings; in Stage 2, those who had chosen to undergo invasive testing were informed about the specific SCA affecting their fetus and their management options. RESULTS Thirty-three cases were classified as SCA-positive by MPS-based testing. After Stage 1 of the two-stage post-test clinical counseling session, 33 (100%) of these pregnant women chose to know the screening test results, and 25 (75.76%) underwent an invasive diagnostic procedure and karyotype analysis, in one of whom karyotyping failed. In thirteen cases, karyotyping confirmed the MPS-based test results (two X0 cases, seven XXX cases, three XXY cases and one XYY case), giving a positive predictive value of 54.17% (13/24 cases confirmed by karyotyping). After post-test clinical counseling session Stage 2, seven women chose to terminate the pregnancy: one X0 case, two XXX cases, the three XXY cases and the single XYY case. Six women decided to continue with pregnancy: one X0 case and five XXX cases. CONCLUSION Our study showed the feasibility of clinical application of the MPS-based test in the non-invasive detection of fetal SCA. Together with a two-stage post-test clinical counseling protocol, it leads to a well-informed decision-making procedure.

Abstract
The incidence of posterior intercostal arteries-induced hemoptysis, its correlation with primary diseases, and the value of interventional embolization therapy were investigated. Clinical data, multislice spiral computed tomography (MSCT), digital subtraction angiography (DSA), and other imaging data of 143 cases of hemoptysis were retrospectively analyzed. After the offending vessels were subjected to interventional embolization therapy, patients were followed-up for observations of clinical efficacies and complications. Thirty-one patients (21.7%) showed 65 branches of posterior intercostal arteries as the non-bronchial systemic arteries involved in hemoptysis; pleural thickening was evident in 25 (80.6%) cases. Posterior intercostal arteries-induced hemoptysis was observed in 16 of the 27 (59.3%) patients with pulmonary tuberculosis, and in 9 of the 10 (90.0%) patients with pulmonary tuberculosis and pulmonary damage. Posterior intercostal arteries-induced hemoptysis was correlated to pleural thickening (P<0.05), which differed significantly among different underlying diseases (P<0.05). Twenty-eight cases of 58 branches of posterior intercostal arteries were found to be involved in hemoptysis by preoperative chest CT angiogram (CTA); the intraoperative matching rates were 90.3% (28/31) and 89.2% (58/65), respectively. Thirty-one patients received transcatheter arterial embolization (TAE), of which 29 (93.5%) showed immediate hemostasis; 1 case had surgical treatment for ineffectuality, and 2 cases showed recurrence without serious complications. The posterior intercostal arteries were commonly involved in hemoptysis, and were closely associated with pleural thickening and pulmonary tuberculosis, especially when accompanied by pulmonary damage. Complete TAE could improve the treatment effect of hemoptysis and preoperative chest CTA was helpful for interventional embolization therapy.

Abstract
The aim of this study was to investigate the association of PAX4 variants with therapeutic effect of oral antidiabetic drugs in Chinese type 2 diabtes mellitus (T2DM) patients. A total of 209 newly diagnosed T2DM patients were randomly assigned to treatment with repaglinide or rosiglitazone for 48 weeks, and the therapeutic effects were compared. In the rosiglitazone cohort, rs6467136 GA+AA carriers showed greater decrease in 2-h glucose levels (P=0.0063) and higher cumulative attainment rates of target 2-h glucose levels (Plog rank=0.0093) than GG homozygotes. In the subgroup with defective β-cell function, rs6467136 GA+AA carriers exhibited greater decrements of 2-h glucose level and improvement of homeostasis model assessment of insulin resistance (P=0.0143). Moreover, GA+AA carriers were more likely to attain the target fasting and 2-h glucose level (Plog rank=0.0091 and 0.007, respectively). However, these single-nucleotide polymorphisms showed no effect on repaglinide efficacy. In conclusion, PAX4 variant rs6467136 was associated with the therapeutic effect of rosiglitazone in Chinese T2DM patients.
