Abstract
OBJECTIVE Alzheimer's disease (AD) has been considered as a metabolic disorder disease, which closely related to insulin signaling impairment. Therefore, identifying the potential mechanism of insulin resistance is important for AD treatment. MATERIALS AND METHODS An APP/PS1 double transgenic AD mouse model was introduced to study insulin resistance in gut. The expressions of AD markers and key elements of insulin signaling were detected in ileum and intestinal macrophages of AD mice by immunohistochemistry. Furthermore, mouse intestinal macrophage cell line RAW264.7 was treated by Aβ25-35 or Aβ25-35 + insulin to explore the mechanism of insulin resistance in vitro. The expression of IR-β and the activation of cell signaling related proteins (Insulin receptor substrate 1 (IRS1), protein kinase B (AKT) and c-Jun N-terminal kinase (JNK)) in Aβ25-35-stimulated macrophages were performed via Western blotting. RESULTS The expressions of IRS1, Aβ and Tuj in AD mice ileum were significantly different from WT mice (p<0.05). Also, there were significant discrepancies in the expressions of β2AR and eNOS in intestinal macrophages of two groups (p<0.05). After exposure to Aβ25-35, cell proliferation rate (p<0.01) of macrophage and the levels of TNF-α (p<0.01) and Il-6 (p<0.01) was significant elevated and treatment with insulin could reverse these changes (p<0.05). The amount of IR-β and the p-AKT/AKT ratio significantly decreased in Aβ25-35-treated macrophages (p<0.01), while the ratios of p-IRS1/IRS1 and p-JNK/JNK significantly enlarged (p<0.01). Furthermore, all the changes caused by Aβ25-35 treatment were attenuated by insulin addition. CONCLUSIONS Activation of JNK pathway played an important role in insulin resistance of AD mice, suggesting that inhibition of JNK pathway might be a new strategy toward resolving insulin resistance related diseases, such as AD.

Abstract
Objective: The study aimed to investigate whether sample sizes of F-wave study differed according to different nerves, different F-wave parameters, and amyotrophic lateral sclerosis(ALS) patients or healthy subjects. Methods: The F-waves in the median, ulnar, tibial, and deep peroneal nerves of 55 amyotrophic lateral sclerosis (ALS) patients and 52 healthy subjects were studied to assess the effect of sample size on the accuracy of measurements of the following F-wave parameters: F-wave minimum latency, maximum latency, mean latency, F-wave persistence, F-wave chronodispersion, mean and maximum F-wave amplitude. A hundred stimuli were used in F-wave study. The values obtained from 100 stimuli were considered "true" values and were compared with the corresponding values from smaller samples of 20, 40, 60 and 80 stimuli. F-wave parameters obtained from different sample sizes were compared between the ALS patients and the normal controls. Results: Significant differences were not detected with samples above 60 stimuli for chronodispersion in all four nerves in normal participants. Significant differences were not detected with samples above 40 stimuli for maximum F-wave amplitude in median, ulnar and tibial nerves in normal participants. When comparing ALS patients and normal controls, significant differences were detected in the maximum (median nerve, Z=-3.560, P<0.01; ulnar nerve, t=5.019, P<0.01; tibial nerve, Z=-2.475, P<0.05; peroneal nerve, Z=-2.088, P<0.05)and mean F-wave latency (median nerve, Z=-3.243, P<0.01; ulnar nerve, t=3.876, P<0.01; tibial nerve, Z=-2.206, P<0.05; peroneal nerve, Z=-2.205, P<0.05)in all four nerves, F-wave chronodispersion (Z=-3.152, P<0.01)in the ulnar nerve, F-wave persistence in the median (Z=6.139, P<0.01)and ulnar nerves(Z=5.350, P<0.01), mean F-wave amplitude in the tibial nerve(t=2.981, P<0.01), maximum F-wave amplitude in the ulnar (Z=-2.134, P<0.05)and tibial nerves (t=2.746, P<0.01)with 20 stimuli; for chronodispersion in tibial nerve (t=2.551, P<0.05)100 stimuli, for chronodispersion in peroneal nerve (Z=-2.086, P<0.05)80 stimuli, for F-wave persistence in tibial nerve (Z=2.119, P<0.05) 60 stimuli, for mean F-wave amplitude in ulnar (Z=-2.552, P<0.05)and peroneal nerve (Z=-2.228, P<0.05)40 stimuli, for maximum F-wave amplitude in peroneal nerve (t=2.693, P<0.01)60 stimuli were necessary to detect differences. Conclusions: Sample sizes of F-wave study differed according to different nerves, different F-wave parameters , and ALS patients or healthy subjects.

Abstract
BACKGROUND Nitric oxide (NO) and mast cells (MCs) are possibly involved in the development of irritable bowel syndrome (IBS), but details on their role and interactions still remain undetermined. We aimed to investigate the expression of inducible NO synthase (iNOS) in MCs of the colon of IBS with diarrhea (IBS-D), and elucidated a potential role of NO in the differential regulation of cytokines in MCs. METHODS Colonic mucosal biopsies of 19 IBS-D patients and 16 healthy controls were collected. The expression of tryptase and iNOS was investigated by immunohistochemistry, Western blotting, and real-time PCR. Effects of NO on the expression of cytokines in rat bone marrow MCs (BMMCs) were examined using a cytokine array by NG-nitro-l-arginine methyl ester (L-NAME) treatment. KEY RESULTS Immunohistochemistry for tryptase revealed an increase in number of MCs with extensive iNOS expression in the colonic mucosa of IBS-D. Tryptase, iNOS and interleukin (IL)-1β mRNA and protein levels were upregulated in IBS-D compared with healthy controls. Specifically, a positive correlation between tryptase and iNOS protein expression was observed in the colon of IBS-D (r = 0.667, p < 0.05). Supernatant from IBS-D increased iNOS expression in BMMCs. Antibody array showed that agrin, beta-nerve growth factor, fractalkine, granulocyte-macrophage colony-stimulating factor, IL-1β, IL-1R6, IL-13, leptin, tumor necrosis factor alpha were suppressed, and cytokine-induced neutrophil chemoattractant (CINC)-1, CINC-2α, CINC-3, monocyte chemotactic protein-1, matrix metalloproteinase-8 were strongly produced in L-NAME treated BMMCs, comparable to levels in the control group. CONCLUSIONS & INFERENCES Our findings provide new evidence that NO is able to regulate many cytokines in MCs that may be involved in the development of IBS.

Abstract
The aim of this study was to evaluate the performance of three new high-risk human papillomavirus (HPV) assays for primary cervical cancer screening, by using self-collected samples, and to identify an HPV assay that could overcome the major obstacles faced during large-scale population-based screening. Two hundred and ten women showing abnormal cervical cytology (and referred for a colposcopy) were recruited in this study. Self-collected samples obtained from all women were tested with the Cobas, Seq, and BioPerfectus Multiplex Real Time HPV assays; simultaneously, clinician-collected samples (from the same women) were tested with the gold-standard Cobas HPV assay. The results of all the assays were consistent. The sensitivity, positive predictive value, and negative predictive value for cervical intraepithelial neoplasia 2+ (CIN2+) and CIN3+ were comparable between the self-collected samples tested with the three new assays and the clinician-collected samples tested with the Cobas HPV assay (P > 0.05). The single-genotype HPV load per sample did not differ significantly between the self- and clinician-collected samples (P = 0.195). In conclusion, the results of this study demonstrated the applicability of the three new HPV assays for primary cervical cancer screening based on self-collection.

Abstract
Studies of genetic diversity and genetic population structure are critical for the conservation and management of endangered species. The Chinese sucker Myxocyprinus asiaticus is a vulnerable monotypic species in China, which is at a risk of decline owing to fluctuations in effective population size and other demographic and environmental factors. We screened 11 microsatellite loci in 214 individuals to assess genetic differentiation in both wild and cultured populations. The single extant wild population had a higher number of alleles (13) than the cultured populations (average 7.3). High levels of genetic diversity, expressed as observed and expected heterozygosity (HO = 0.771, HE = 0.748, respectively), were found in both wild and cultured populations. We also report significant differentiation among wild and cultured populations (global FST = 0.023, P < 0.001). Both STRUCTURE analysis and neighbor-joining tree revealed three moderately divergent primary genetic clusters: the wild Yangtze population and the Sichuan population were each identified as an individual cluster, with the remaining populations clustered together. Twenty-two samples collected from the Yangtze River were assigned to the cultured population, demonstrating the efficacy of artificial propagation to avoid drastic reduction in the population size of M. asiaticus. These genetic data support the endangered status of the M. asiaticus and have implications for conservation management planning.

Abstract
OBJECTIVE The aim of this study is to analyze application effects of specialized emergency nursing mode based on Global Registry Acute Coronary Events (GRACE) scoring system on Acute Coronary System (ACS) patients. PATIENTS AND METHODS 135 ACS cases in this hospital of the same period were selected and they were divided into control group (65 cases) and observation group (70 cases) according to random number method and their order of hospitalization. The standard specialized nursing mode was applied in the control group while specialized nursing mode based on GRACE scoring system was applied in observation group to compare treatment effects. RESULTS We found that average time of Door-to-Balloon, surgery time and length of stay in observation group were shortened and the occurrence rate of complications during and after surgery was significantly lowered. The remedy achievement ratio and satisfaction scores on nursing are increased and differences were of statistical significance (p<0.05). CONCLUSIONS The stratified nursing was used to ACS patients based on GRACE scoring system, which was able to significantly increase remedy achievement ratio and decrease complications and, therefore, nursing quality is improved.

Abstract
BACKGROUND Chili consumption may have a beneficial effect on muscle strength in the general population. The aim of this study was to investigate the relationship between frequency of chili consumption and handgrip strength in adults. DESIGN Population-based cross-sectional study. SETTING This study used baseline data from the Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study. PARTICIPANTS A total of 3 717 subjects were recruited to the study. Frequency of chili consumption during the previous month was assessed using a valid self-administered food frequency questionnaire. Analysis of covariance was used to examine the relationship between muscle strength and frequency of chili consumption. Handgrip strength was measured using a handheld digital dynamometer. RESULTS After adjustment for potential confounding factors, significant relationships were observed between different categories of chili consumption and handgrip strength in males, the means (95% confidence interval) for handgrip strength across chili consumption categories were 44.7 (42.1, 47.2) for < one time/week; 45.5 (42.9, 48.1) for one time/week; and 45.8 (43.3, 48.4) for ≥ 2-3 times/week (P for trend < 0.01). Similar results were not observed with sweet pepper consumption. CONCLUSIONS This study reveals a positive correlation between frequency of chili consumption and muscle strength in adult males. Further studies are necessary in order to determine whether there is a causal relationship between chili consumption frequency and muscle strength.

Abstract
OBJECTIVE To investigate the effects of atorvastatin combined with trimetazidine on periprocedural myocardial injury and serum inflammatory mediators in unstable angina pectoris (UAP) patients following percutaneous coronary intervention (PCI) treatment. PATIENTS AND METHODS 90 patients with UAP treated with conventional medications and PCI were recruited and were randomly divided into the control group and the experimental group. The control group had 42 patients were treated with atorvastatin alone, while the experimental group had 48 cases treated with atorvastatin combined with trimetazidine. All the patients were checked the preoperative 24h and postoperative 24h PCI concentrations of cardiac troponin I (cTnI), hypersensitive C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α), serum interferon-γ (IFN-γ) and interlukin-10 (IL-10). RESULTS At the pre-PCI stage, every serum factors was no significant difference. 24 hours after the PCI intervention, the occurence of abnormal cTnI level in the experimental group was remarkable reduced than the control group. In the experimental group, the serum levels of TNF-α and IFN-γ significantly decreased (p < 0.05); while IL-10 was increased. In the control group, all the mediators were increased significantly except the hs-CRP (p < 0.05). CONCLUSIONS No unexpected symptom was found in patients with large dose atorvastatin combined with large dose trimetazidine. The administration of conventional medications together with the atorvastatin plus trimetazidine were able to reduce the prevalence of postoperative myocardial injury.

Abstract
Macroparticle contamination deteriorates the qualities and performances of protective coatings by arc ion plating, resulting in a limitation in their applications. In this work, the effects of transverse magnetic field (TMF), pulsed bias, gas pressure, and substrate position on behavior of the macro-particles (MPs) in TiN films are quantitatively investigated. It is demonstrated that the key factor of the deposition process on the MPs behavior is magnetic field, which controls the movement of arc spot significantly. At relatively low magnetic field intensity, the MPs behavior is greatly influenced by the other three process parameters. The sensibilities of the three parameters on MPs behavior are decreased with the increasing magnetic field intensity. At high magnetic field intensity, the MPs distribution keeps almost the same even when the other parameters are varied.

Abstract
The objective of this study was to find the key regulatory molecules in the cell senescence process through observing the expression of telomere-associated factor during the normal cell replicative senescence process. Based on the established cell replicative senescence model, reverse transcription-polymerase chain reaction and western blot analyses were used to detect telomere-associated factor expression at the mRNA and protein levels, including that of human telomere binding protein 1, tankyrase 1, telomerase RNA, telomere protection protein 1 (POT1), and p53 during the process of human embryonic lung fibroblast replicative senescence. The results showed that transcription of human telomere binding protein 1 did not change with cell senescence, whereas the protein expression of human telomere binding protein 1 increased gradually and then decreased rapidly; there was no change in the mRNA and protein expression of POT1; with the replicative senescence of human embryonic lung fibroblasts, expression of POT1 decreased gradually; TRF1 showed an increasing trend with cell senescence; and p53 protein expression did not change. Together, the results from this study suggest that human telomere binding protein 1, POT1, and TRF1 played important roles in cell senescence.

Abstract
White spot disease remains a constant threat to aquaculture worldwide. Hyperthermia has been shown to reduce mortality in white spot syndrome virus (WSSV)-infected shrimps, but the mechanism still remains unclear. In this study, we sought to identify host immune factors that contribute to inhibition of WSSV infection during hyperthermia. In WSSV-infected red swamp crayfish Procambarus clarkii (Girard) cultured at 24 ± 1 °C, transcriptional levels of the heat shock protein 70 (Hsp70) gene showed a modest, 2.2-fold increase in haemocytes following 48 h post-infection (hpi). In contrast, in WSSV-infected crayfish cultured at 32 ± 1 °C, Hsp70 gene expression showed a rapid, 19.5-fold induction by 4 hpi. This suggests that Hsp70 plays a positive regulatory role in resistance to WSSV infection during hyperthermia. Furthermore, total haemocyte counts (THC) and phenoloxidase (PO) activity were both significantly increased in WSSV-infected crayfish cultured at 32 ± 1 °C by 48 hpi. Both may be critical for crayfish survival in the late stages of WSSV infection. Collectively, the up-regulation of host protein Hsp70 expression and increase in THC and PO activity suggest that hyperthermia has immunomodulatory effect that enhanced the resistance of P. clarkii to WSSV infection.

Abstract
OBJECTIVE To identify risk factors for group B streptococcus (GBS) colonization in a subsequent pregnancy using microbiological and clinical data from a prior pregnancy. STUDY DESIGN A retrospective cohort study of women over a 10-year period, using laboratory records to identify women with GBS culture results available in two successive pregnancies. RESULT One thousand eight hundred and ninety-four women met eligibility criteria. Of these, 1293 were not GBS-colonized in either pregnancy, 198 were colonized in both pregnancies and 403 had discordant colonization status. GBS colonization in the index pregnancy was positively associated with multiparity, premature delivery and lower maternal age and negatively associated with chorioamnionitis. The strongest predictor of colonization in a subsequent pregnancy was colonization in the index pregnancy (50% likelihood if colonized compared with 14% if not in the index pregnancy, relative risk 3.6, confidence interval (CI)=3.1 to 4.3). GBS colonization in the subsequent pregnancy was independently associated with: GBS colonization in the index pregnancy (odds ratio (OR)=6.28; CI=4.91 to 8.05), preterm delivery in the index pregnancy (OR=1.80; CI=1.05 to 3.09) and prior early pregnancy loss (OR=1.15; CI=1.04 to 1.27). CONCLUSION GBS colonization in a prior pregnancy is informative of colonization in a subsequent pregnancy. These data support providing antimicrobial prophylaxis in unscreened parous women with known prior GBS colonization.

Abstract
Obesity is a strong determinant of blood pressure. Uncertainty remains, however, about which indices of adiposity most strongly predict blood pressure, particularly among those who were relatively lean, such as those from rural China. We analyzed cross-sectional data on 55 687 (38.3% men) participants aged 30–79 years who were enrolled into the China Kadoorie Biobank from a rural county in southwest of China during 2004–2008. Measured body mass index (BMI) and waist circumference (WC) were related to blood pressure in multivariable linear regression analyses. The overall mean values of BMI, WC, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 23.3 kg m−2, 78.0 cm, 129.2 mm Hg and 77.2 mm Hg, respectively. There was a strongly positive, and apparently linear, relationship of BMI and WC with blood pressure, with 1 s.d. higher BMI associated with 4.3/2.3 mm Hg higher SBP/DBP and 1 s.d. WC associated with 3.8/2.1 mm Hg (P<0.0001). Additional adjustment for WC only slightly attenuated the association of BMI with blood pressure, whereas additional adjustment for BMI almost completely eliminated the association of WC with blood pressure. Our findings suggest that in relatively lean Chinese adults, general adiposity is more strongly assciated with blood pressure than central adiposity.

Abstract
BACKGROUND/OBJECTIVES Previous studies have indicated that higher levels of food consumption are associated with fatty liver disease (FLD), but few studies have investigated the relationship between this disease and different dietary patterns. The aim of this cross-sectional study was to examine the association between dietary patterns and FLD in adults. SUBJECTS/METHODS Dietary intakes of participants in the Tianjin were assessed via questionnaire. Factor analysis was used to identify dietary patterns, and FLD was defined as having a FLD diagnosis using liver ultrasonography. Relationships between dietary patterns and FLD were assessed using multiple logistic regression analysis. RESULTS Female participants in the highest quartile of high-carbohydrate/sweet pattern scores had a 2.19-fold greater risk (95% confidence interval (CI), 1.40-3.46) of developing non-alcoholic FLD (NAFLD) than those in the lowest quartile after adjusting for confounding factors. No significant differences were found between any dietary pattern and NAFLD in males. In males, a significantly increasing trend of alcoholic FLD (AFLD) prevalence was associated with increasing high-protein/cholesterol pattern scores (P for trend = 0.03; odds ratio (OR), 2.08; 95% CI, 1.15-3.81) while an increased high-carbohydrate/sweet pattern score appeared protective against AFLD (P for trend = 0.02; OR, 0.55; 95% CI, 0.29-1.00). CONCLUSIONS Our study demonstrates that high-protein/cholesterol pattern scores are associated with higher prevalence of AFLD in males. We also show high-carbohydrate/sweet pattern scores are associated with higher prevalence of NAFLD in females; but, interestingly, this pattern shows a favorable effect on AFLD in males.

Abstract
INTRODUCTION Preoperative characterisation of ovarian masses into benign or malignant is of paramount importance to optimise patient management. OBJECTIVES In this study, we developed and validated a computerised model to characterise ovarian masses as benign or malignant. MATERIALS AND METHODS Transvaginal 2D B mode static ultrasound images of 187 ovarian masses with known histological diagnosis were included. Images were first pre-processed and enhanced, and Local Binary Pattern Histograms were then extracted from 2 × 2 blocks of each image. A Support Vector Machine (SVM) was trained using stratified cross validation with randomised sampling. The process was repeated 15 times and in each round 100 images were randomly selected. RESULTS The SVM classified the original non-treated static images as benign or malignant masses with an average accuracy of 0.62 (95% CI: 0.59-0.65). This performance significantly improved to an average accuracy of 0.77 (95% CI: 0.75-0.79) when images were pre-processed, enhanced and treated with a Local Binary Pattern operator (mean difference 0.15: 95% 0.11-0.19, p < 0.0001, two-tailed t test). CONCLUSION We have shown that an SVM can classify static 2D B mode ultrasound images of ovarian masses into benign and malignant categories. The accuracy improves if texture related LBP features extracted from the images are considered.

Abstract
OBJECTIVE To analyze the clinical and molecular characteristics of patients with X-linked thrombocytopenia (XLT) and their responsiveness to treatment with various doses of corticosteroids or intravenous immunoglobulin (IVIG) separately. METHOD Data from 15 XLT patients who were hospitalized in Children's Hospital Affiliated to Chongqing Medical University from March 2010 to July 2014 were analyzed retrospectively, including clinical manifestations, scores, peripheral blood, immunological functions, responses to IVIG and steroid treatment with various doses and duration. RESULT All 15 XLT patients met the inclusion criteria and showed microthrombocytopenia with or without mild-to-moderate eczema or minor infections. Platelet counts ranged from (8-80) × 10⁹/L. The platelet volume value ranged between 5.6 and 10.9 fl (normal range: 9.4-12.5 fl). Raised serum IgG was found in 5 cases, while low serum IgG was found in 2 cases. WAS gene analysis revealed missense mutations in 14 patients, including 4 hotspots (V75M, R86C, R86H, R86L) and 1 novel mutation (Y107C). Flow cytometer analysis of 13 patients showed various amounts of WAS protein (WASP) expression, 2 patients had normal amounts of WASP expression, 5 had reduced amounts, and 6 had absent WASP expression. Their responses to individual steroid and IVIG treatment with various doses and duration were also reviewed. Fourteen patients who were misdiagnosed as immune thrombocytopenic purpura at first received 28 courses of steroids and (or) 47 courses of IVIG treatment. The post-treatment platelet counts of 1 000-2 000 mg/(kg × d) IVIG(25 courses) at 2-7 d and 8-14 d time points were (60 ± 10) × 10⁹/L and (41 ± 7) × 10⁹/L, which indicate a significantly better responsiveness than those by [(31 ± 7) × 10⁹/L, (21 ± 2) × 10⁹/L] of 400-500 mg/(kg·d) IVIG(22 courses) (Z = -4.419, -1.592;P = 0.002,0.011). However, there were no significant differences between the responsiveness of 3 doses [1-2 mg/(kg·d)(8 courses), 3-6 mg/(kg·d) (11 courses) and 20-30 mg/(kg × d)(9 courses)] of steroids (F = 0.387,0.252;P = 0.980,0.761) at 2-7 d and 8-14 d time points. The platelet counts gradually decreased to the primary level at 15-30 d after any doses of steroids and (or) IVIG treatment. The effective rate of 1 000-2 000 mg/(kg × d) IVIG treatment was 18/25, which was significantly higher than that (2/22) of 400-500 mg/(kg × d) (χ² = 9.836, P = 0.008). The effective rate of 20-30 mg/(kg × d) steroids treatment (7/9) was relatively higher than 1-2 mg/(kg × d) (4/8) and 3-6 mg/(kg × d) (6/11) with no significant difference (χ⁹ = 3.235, P = 0.581). After the treatment with steroids and /or IVIG 14 cases with hemorrhage were all improved. CONCLUSION The clinical characteristics of X-linked thrombocytopenia were microthrombocytopenia with or without mild-to-moderate eczema or minor infections. WAS gene and WASP analysis were diagnostic methods. There were no significant differences between the responsiveness of 3 doses of steroids; 1 000-2 000 mg/(kg·d) IVIG had a significantly better responsiveness. However, IVIG and steroids with any dose and duration may only transiently increase peripheral platelet level of XLT patients.

Abstract
Molecular rotors may be utilized as non-invasive, non-disruptive and highly sensitive alternatives to conventional measures of bulk viscosity when the oil is entrained in a colloidal fat crystal network. Oil viscosity changes based on the molecular confinement of the oil, which is dependent on its molecular volume. Changes in micro-viscosity were not dependent on the solids content, but instead were strongly dependent on the box-counting fractal dimension in high-space filling colloidal fat crystal networks (i.e., D > 1.89). A bulk oil viscosity is often an overestimation of the actual viscosity of the entrained oil and may not be appropriate when predicting diffusion in multi-phase materials.

Abstract
Formononetin is a naturally existing isoflavone, which can be found in the roots of Astragalus membranaceus, Trifolium pratense, Glycyrrhiza glabra, and Pueraria lobata. It was found to be associated with inhibition of cell proliferation and cell cycle progression, as well as induction of apoptosis in various cancer cell lines. However, the effect of formononetin on breast cancer cell metastasis remains unclear. In this study, we examined the effect of formononetin on the migration and invasion of breast cancer cells MDA-MB-231 and 4T1 in vitro and in vivo. Our data demonstrated that formononetin did not effectively inhibit the cell viability of MDA-MB-231 and 4T1 in 24 h with the concentration lower than 160 μmol/l. When treated with nontoxic concentration of formononetin, the migration and invasion of MDA-MB-231 and 4T1 cells were markedly suppressed by wound healing assay, chamber invasion assay, and in vivo mouse metastasis model. In vitro, formononetin reduced the expression of matrix metalloproteinase-2 (MMP-2), MMP-9 and increased the expression of tissue inhibitor of metalloproteinase-1 (TIMP-1) and TIMP-2. Furthermore, the immunofluorescence and immunoblotting assays indicated that formononetin was very effective in suppressing the phosphorylation of Akt and PI3K. Collectively, these results suggest that formononetin inhibited breast cancer cell migration and invasion by reducing the expression of MMP-2 and MMP-9 through the PI3K/AKT signaling pathway. These findings demonstrate a potentially new therapeutic strategy of formononetin as anti-invasive agent for breast cancer.

Abstract
Platinum-induced ovarian impairment is a consequence of treatment for malignant ovarian tumors. We compared the protective effects of Ginkgo flavonoids, amifostine, and leuprorelin on ovarian impairment in rats. Fifty rats were randomly divided into the A, B, C, D, and E groups, which were given saline, cisplatin, cisplatin plus Ginkgo flavonoids, cisplatin plus amifostine, and cisplatin plus leuprorelin, respectively. Ovarian weight was significantly greater in groups C and D compared with group B (83.5 ± 6.7 and 86.8 ± 10 vs 56.8 ± 5.4 mg). The total follicle numbers were higher in groups C, D, and E than in group B (60.5 ± 3.9, 63.8 ± 5.1, and 67.7 ± 3.5 vs 49.6 ± 4.5), and the apoptotic index was reduced in groups C, D, and E compared with group B (35.7 ± 2.0, 37.4 ± 1.6, and 30.5 ± 2.9 vs 65.3 ± 2.9%). The ovaries in groups B, C, and D had higher protein and mRNA expression levels of cytoplasmic Cytochrome c (Cyt-c) and apoptotic protease activating factor-1 (Apf-1) compared to group A; the Cyt-c mRNA expression was five-fold higher. The mRNA expression of Cyt-c and Apf-1 were significantly lower in groups C, D, and E compared with group B. Administration of leuprorelin, flavonoids, or amifostine protected rats against the ovarian impairment induced by prior intraperitoneal injection of cisplatin. The efficacy of leuprorelin was superior to that of Ginkgo flavonoids and amifostine, but there was no difference between the effects of Ginkgo flavonoids and amifostine.

Abstract
Inflammation critically contributes to cancer metastasis, in which myeloid-derived suppressor cells (MDSCs) are an important participant. Although MDSCs are known to suppress immune surveillance, their roles in directly stimulating cancer cell proliferation and metastasis currently remain unclear. Lysosomal acid lipase (LAL) deficiency causes systemic expansion and infiltration of MDSCs in multiple organs and subsequent inflammation. In the LAL-deficient (lal−/−) mouse model, melanoma metastasized massively in allogeneic lal−/− mice, which was suppressed in allogeneic lal+/+ mice due to immune rejection. Here we report for the first time that MDSCs from lal−/− mice directly stimulated B16 melanoma cell in vitro proliferation, and in vivo growth and metastasis. Cytokines i.e., IL-1β and TNFα from MDSCs are required for B16 melanoma cell proliferation in vitro. Myeloid-specific expression of human LAL (hLAL) in lal−/− mice rescues these malignant phenotypes in vitro and in vivo. The tumor-promoting function of lal−/− MDSCs is mediated, at least in part, through over-activation of the mammalian target of rapamycin (mTOR) pathway. Knockdown of mTOR, Raptor or Rictor in lal−/− MDSCs suppressed their stimulation on proliferation of cancer cells, including B16 melanoma, LLC and Tramp-C2 cancer cells. Our results indicate that LAL plays a critical role in regulating MDSCs ability to directly stimulate cancer cell proliferation, and overcome immune rejection of cancer metastasis in allogeneic mice through modulation of the mTOR pathway, which provides a mechanistic basis for targeting MDSCs to reduce the risk of cancer metastasis. Therefore, MDSCs possess dual functions to facilitate cancer metastasis: suppress immune surveillance, and stimulate cancer cell proliferation and growth.

Abstract
Benzo(a)pyrene-7,8-diol-9,10-epoxide (BPDE) is a highly reactive DNA damage agent and can induce cell death through both p53-independent and -dependent pathways. However, little is known about the molecular mechanisms of p53-independent pathways in BPDE-induced cell death. To understand the p53-independent mechanisms, we have now examined BPDE-induced cytotoxicity in p53-deficient baby mouse kidney (BMK) cells. The results showed that BPDE could induce Bax and Bak activation, cytochrome c release, caspases activation, and necrotic cell death in the BMK cells. Bax and Bak, two key molecules of mitochondrial permeability transition pore, were interdependently activated by BPDE, with Bax and Bak translocation to and Bax/Bak homo-oligomerization in mitochondria, release of cytochrome c was induced. Importantly, cytochrome c release and necrotic cell death were diminished in BMK cells (Bax−/−), BMK cells (Bak−/−), and BMK cells (Bax−/−/Bak−/−). Furthermore, overexpression of Bcl-2 could ameliorate BPDE-induced cytochrome c release and necrosis. Together the findings suggested that BPDE-induced necrosis was modulated by the p53-independent pathway, which was related to the translocation of Bax and Bak to mitochondria, release of cytochrome c, and activation of caspases.

Abstract
AIMS To examine single nucleotide polymorphisms in the protein tyrosine phosphatase N22 gene (PTPN22) and to study their association with Type 1 diabetes in a Chinese cohort. METHODS Three hundred and sixty-four young patients with Type 1 diabetes and 719 healthy children were included in this case-controlled study. The genotypes of rs1217385, rs2488457 (-1123C>G), rs1217414, rs1217419, rs3765598 and rs2476601 (1858C>T) in the PTPN22 gene were determined using the SNaPshot method. Alleles, genotypes and haplotype frequencies were compared between patients with Type 1 diabetes and healthy control subjects. The association between single nucleotide polymorphisms and clinical traits/autoantibody status was also analysed. RESULTS The single nucleotide polymorphism, rs1217419, located in the second intron of the PTPN22 gene was associated with Type 1 diabetes (odds ratio 1.5, 95% CI 1.14-1.97, P = 0.003). An additional single nucleotide polymorphism, rs1217385, was also associated with Type 1 diabetes; however, the association was secondary to that of rs1217419. The previously reported single nucleotide polymorphism that is associated with Type 1 diabetes (-1123G>C) had only marginal association with Type 1 diabetes in our study. A marginal association was also identified between -1123G>C and glutamic acid decarboxylase autoantibody positivity in patients with Type 1 diabetes. There was no association between the single nucleotide polymorphism 1858C>T and Type 1 diabetes in our studied cohort. CONCLUSIONS Our study confirmed that PTPN22 is a gene that contributes to Type 1 diabetes susceptibility. The primary association occurs with single nucleotide polymorphism rs1217419 and there is clear heterogeneity of the association between PTPTN22 polymorphisms and Type 1 diabetes in a Chinese population compared with other populations.

Abstract
Crystallization process in a fluidized bed reactor (FBR) has been regarded as an environmentally friendly technology for the removal and recovery of fluoride from industrial wastewater. The growth kinetics of calcium fluoride at high supersaturation was studied for design, control, and operation of an FBR. The main variables, including supersaturation, superficial velocity, pH value, and particle size of seed that influenced the crystal growth were investigated. Then, a growth model was used to predict the linear growth rate of calcium fluoride at a high influent concentration of fluoride. The pressure difference in the FBR was used as a feature to characterize the growth rate of calcium fluoride. The aggregation and adsorption between seeds and fine particles were proven to be a possible mechanism for growth of calcium fluoride.

Abstract
Endoscopic submucosal dissection (ESD) has been widely used for resection of esophageal neoplastic lesions, but there are still technical challenges in treating large ones. Based on the development of tunneling technique, we report the first series in which the new technique of endoscopic submucosal tunnel dissection (ESTD) was used to remove large lesions in the esophagus. ESTD was attempted in five consecutive patients with esophageal lesions for which resection was indicated. In the operation, once the margin of the lesions had been marked, a submucosal tunnel was created by submucosal dissection from the oral incision to the anal incision. Bilateral resection was then performed to remove the lesion completely. The average length of the five lesions was 5.7 cm, and their extent as a proportion of the whole circumference of the lumen ranged from one third to four fifths. Operative time ranged from 50 minutes to 120 minutes (mean, 77 minutes). En bloc resection with negative lateral and basal margins was achieved in all lesions without complications.

Abstract
OBJECTIVE To investigate the expression and role of oxidative stress markers in the serum and follicular fluid of patients with endometriosis. MATERIALS AND METHODS A prospective case-control study was conducted in 42 patients who underwent in vitro fertilization-embryo transfer (IVF-ET). They were divided into Group I: patients with endometriosis (n = 20) and Group II: patients with tubal factor infertility (n = 22). All patients underwent a long gonadotropin-releasing hormone (GnRH) agonist protocol for pituitary downregulation followed by controlled ovarian hyperstimulation. Level of reactive oxygen species (ROS), superoxide dismutase (SOD), and vitamin E (VE) were measured by enzyme-linked immunosorbent assay (ELISA). The results of IVF-ET between the two groups were compared. RESULTS The ROS levels in both serum and follicular fluid of the study group were significantly higher than in the control group. The serum levels of SOD and VE in the study group were significantly lower than those in the control group, but there was no difference in follicular fluid levels of SOD and VE between the two groups. Furthermore, the mature oocyte and fertilization rates in the study group were significantly lower than those of the control group. However, the levels of ROS, SOD, and VE in serum and follicular fluid were not significantly correlated with outcome following IVF-ET. CONCLUSION Patients with endometriosis have increased oxidative stress, as well as lower mature oocyte rates and fertilization rates. Nevertheless, there is no evidence that the oxidative stress status is directly related to the outcome of IVF treatment.

Abstract
Objective: This study investigated associations between polymorphisms in the vascular endothelial growth factor (VEGF) gene and susceptibility to acute mountain sickness. Methods: Two hundred Han Chinese soldiers who developed acute mountain sickness after rapidly ascending to an altitude of < 3600 m and 200 control soldiers (who did not develop the condition) were enrolled in the study. Twelve single nucleotide polymorphisms (SNPs) of the VEGF gene were genotyped in all the study participants. Plasma VEGF concentrations were measured by enzyme-linked immunosorbent assay in 40 subjects with acute mountain sickness and 40 controls before and after exposure to high altitude. Results: The frequencies of the rs3025039 genotype and allele were significantly different between the groups. Two SNPs, rs3025039 (which involves a C→T allele variation at position 936 in the 3′ untranslated region) and rs3025030 (which involves a G→C allele variation in the intronic sequence), were associated with a decreased risk of acute mountain sickness. Conclusion: The SNPs rs3025039 and rs3025030 of the VEGF gene may be associated with a decreased risk of acute mountain sickness development.

Abstract
BACKGROUND The leptin receptor (LEPR) is an important regulator of leptin activity and resistance. Several single nucleotide polymorphisms (SNP) of LEPR have been linked to diseases accompanying obesity and/or obesity-related diseases in different populations. However, the results from published studies remain inconsistent rather than conclusive. AIM To investigate whether LEPR SNP are associated with essential hypertension and related metabolic traits in Chinese subjects. MATERIALS AND METHODS A total of 544 Chinese patients with hypertension and 357 non-hypertensive subjects were screened. The genotypes of LEPR polymorphisms were determined by PCR-restriction fragment length polymorphism methods. Demographic and biochemical characteristics including waist circumference, waist-to-hip ratio, body mass index (BMI), lipids profiles, glucose metabolism, and leptin levels were obtained for analysis. RESULTS This case-control study showed associations between the frequencies of AA genotype and A allele of Gln223Arg and hypertension (p=0.029, p=0.002, respectively). Furthermore, the Gln223Arg polymorphism was significantly associated with plasma leptin levels (p<0.001), while no correlations between Lys109Arg SNP and hypertension were found. Multivariate logistic regression analysis evidenced that A allele carriers of Gln223Arg (AA+AG) showed higher risks of hypertension than GG carriers after adjustment of age and sex (adjusted odds ratio: 1.549, 95% confidence interval: 1.031- 2.036, p=0.035). BMI, fasting serum insulin, oral glucose tolernace test (OGTT)-2h glucose, serum leptin, as well as LDL-cholesterol (LDL-C) levels were also independent risk factors of hypertension in this population. In addition, significant associations were observed between the Gln223Arg and Lys109Arg SNP and serum total cholesterol, LDL-C, and fasting plasma glucose levels in hypertensive patients. Besides, A allele of Gln223Arg had raised diastolic blood pressure, compared with GG carriers (p=0.001). While variance of Lys109Arg was associated with waist-to-hip ratio, OGTT-2h glucose, and homeostasis model assessment of insulin resistance (p<0.05). CONCLUSIONS LEPR polymorphisms may be a marker for susceptibility to essential hypertension in Chinese subjects, and be involved in the development of several features including dyslipidemia and impaired glucose regulation in hypertension subjects.

Abstract
AIM To investigate clinical presentation and genotypes in patients with simultaneous geographic atrophy (GA) and choroidal neovascularization (CNV) and to compare with patients with GA or CNV only. PATIENTS AND METHODS Twenty patients with combined CNV-GA and 154 CNV only and 154 GA only were chosen based on clinical exam and imaging. Six single-nucleotide polymorphisms (SNPs)-rs2274700 and rs1061170 (complement factor H), rs10490924 and rs11200638 (HTRA1/LOC387715), rs2230199 (C3), rs9332739 (C2)-were genotyped using the SNaPshot method. Chi-squared tests were used for genetic analysis. RESULTS In patients with CNV-GA, GA progressed slowly and often preceded CNV. CNV presented as subretinal haemorrhage or fluid, with a sudden drop in visual acuity (VA). Comparing combined CNV-GA to GA and CNV only, patients with both had a higher frequency of at-risk alleles at both SNPs within the HTRA1 gene-rs10490924 (52.5%), rs11200638 (52.6%). Statistical significance was not achieved. CNV-GA patients had no protective alleles at SNP rs9332739 (C2), compared with GA (27%) and CNV only (10%). CONCLUSION There is a paucity of reports describing simultaneous CNV-GA. Clinical and genetic results may support the fact that GA and CNV fit on an age-related macular degeneration (AMD)-disease continuum and may clarify the disease processes in AMD.

Abstract
From 2006 to 2009, 27 ultrasonic-tagged wild adult Chinese sturgeon Acipenser sinensis [eight males, 19 females; total length (L(T)) range = 245-368 cm] were captured on the spawning ground just downstream of Gezhouba Dam (GZD) in the Yangtze River. Twenty-six individuals were tracked for 7 to 707 days (mean number of relocations = 859; range = 3-4549). Acipenser sinensis movements were divided into four categories: (1) spawning migration, two tagged A. sinensis (one female and one male) returned to the Yangtze River and migrated from the Yangtze Estuary (river kilometer, rkm, 0) to the spawning ground (1678 rkm) between June and October. Their mean upstream ground speed was 1.41 km h(-1) (range = 0.26-2.35 km h(-1) ). The speed of the male was faster than the female; (2) pre-spawning holding, four of five females tagged in November 2008 stayed within 1678.00-1674.15 rkm for c. 1 year before the spawning period; (3) spawning movements, all A. sinensis swam mostly from the tailrace of the GZD (1678 rkm) to the Miaozui (1674.15 rkm) reach and some moved downstream c. 18.21 rkm (range = 3.93-24.64 rkm), but then, returned upstream to the GZD. Most tagged A. sinensis were on the spawning ground on the day when the spawning occurred; (4) post-spawning migration males (n = 6) and females (n = 2) departed the spawning area on a different time schedule, females leaving before males. The mean seaward ground speed of six A. sinensis was 4.87 km h(-1) (range = 0.68-7.60 km h(-1) ). There were no significant differences (P > 0.05) in ground speeds among reaches or between sexes within reaches between telemetry receivers. These broad spatiotemporal scale results will help establish an effective protection strategy for the species in the Yangtze River.

Abstract
We have examined the effect of adenoviruses expressing soluble transforming growth factor receptorII-Fc (sTGFβRIIFc) in a 4T1 mouse mammary tumor bone metastasis model using syngeneic BALB/c mice. Infection of 4T1 cells with a non-replicating adenovirus, Ad(E1-).sTβRFc, or with two oncolytic adenoviruses, Ad.sTβRFc and TAd.sTβRFc, expressing sTGFβRIIFc (the human TERT promoter drives viral replication in TAd.sTβRFc) produced sTGFβRIIFc protein. Oncolytic adenoviruses produced viral replication and induced cytotoxicity in 4T1 cells. 4T1 cells were resistant to the cytotoxic effects of TGFβ-1 (up to 10 ng ml(-1)). However, TGFβ-1 induced the phosphorylation of SMAD2 and SMAD3, which were inhibited by co-incubation with sTGFβRIIFc protein. TGFβ-1 also induced interleukin-11, a well-known osteolytic factor. Intracardiac injection of 4T1-luc2 cells produced bone metastases by day 4. Intravenous injection of Ad.sTβRFc (on days 5 and 7) followed by bioluminescence imaging (BLI) of mice on days 7, 11 and 14 in tumor-bearing mice indicated inhibition of bone metastasis progression (P<0.05). X-ray radiography of mice on day 14 showed a significant reduction of the lesion size by Ad.sTβRFc (P<0.01) and TAd.sTβRFc (P<0.05). Replication-deficient virus Ad(E1-).sTβRFc expressing sTGFβRIIFc showed some inhibition of bone metastasis, whereas Ad(E1-).Null was not effective in inhibiting bone metastases. Thus, systemic administration of Ad.sTβRFc and TAd.sTβRFc can inhibit bone metastasis in the 4T1 mouse mammary tumor model, and can be developed as potential anti-tumor agents for breast cancer.
