Abstract
Spodoptera litura is a widespread polyphagous insect pest that can develop resistance and cross-resistance to insecticides, making it difficult to control. Insecticide exposure has previously been linked with induction of specific olfactory-related proteins, including some chemosensory proteins (CSPs) and odorant-binding proteins (OPBs), which may disrupt detection of environmental factors and reduce fitness. However, functional evidence supporting insecticide and OBPs/CSPs mediation remains unknown. Here we fed male S. litura moths with sucrose water containing one of three insecticides, chlorpyrifos, emamectin benzoate or fipronil, and used real-time quantitative polymerase chain reaction and RNAi to investigate OBPs and CSPs expression and their correlations with survival. Chlorpyrifos and emamectin benzoate increased expression of 78% of OBPs, plus 63 and 56% of CSP genes, respectively, indicating a major impact on these gene families. RNAi knockdown of SlituCSP18, followed by feeding with chlorpyrifos or fipronil, decreased survival rates of male moths significantly compared with controls. Survival rate also decreased significantly with the downregulation of SlituOBP9 followed by feeding with chlorpyrifos. Thus, although these three insecticides had different effects on OBP and CSP gene expression, we hypothesize that SlituOBPs and SlituCSPs might mediate their effects by increasing their expression levels to improve survival. Moreover, the differential response of S. litura male moths to the three insecticides indicated the potential specificity of chlorpyrifos affect SlituCSP18 and SlituOBP9 expression.

Abstract
The integrity and normal function of the small intestinal epithelium depends critically on the rapid renewal of epithelial cells from basal stem cells. The intensive proliferation that fuels this self-renewal process is confined to the intestinal crypts. Establishment of suitable protocols for crypt isolation and culture is pivotal for the studies of intestinal self-renewal mechanisms. In this study, chicken small intestinal crypts were isolated, purified, and further cultured in a Matrigel 3-D culture system. The growth factor concentration assay on the fourth d of culture showed that Group C (50 ng/mL epidermal growth factor (EGF), 100 ng/mL Noggin, and 500 ng/mL R-spondin 1) supplement in culture medium could significantly enlarge the diameter of organoids when compared with Group A (5 ng/mL EGF, 10 ng/mL Noggin, 50 ng/mL, and R-spondin 1) and Group B (10 ng/mL EGF, 20 ng/mL Noggin, and 100 ng/mL R-spondin 1) by 188.4% (P = 0.026) and 176.9% (P = 0.034), respectively. Transmission electron microscopy, neutral red staining, and 5-ethynyl-2΄-deoxyuridine incorporation demonstrated the integrated structure, high viability, and proliferative activity in cultured chicken intestinal organoids. In addition, intestinal stem cell marker genes (Olfm4, Znrf3, Hopx, and Lgr5) also could be detected in cultured intestinal organoids. Furthermore, CHIR99021 (a glycogen synthase kinase 3β inhibitor) could enhance the expression of Olfm4, Znrf3, Hopx, and Lgr5 by 750% (P = 0.001), 467% (P < 0.001), 450% (P < 0.001), and 333% (P = 0.008), respectively, indicating the responsiveness of the cultured chicken intestinal organoids to exogenous stimulus. This study modified a murine culture model and optimized it to provide a chicken intestinal organoid model for use as a physiological or pathological research platform in vitro.

Abstract
Introduction We present our experiences using a modified surgical approach from the edge of the tragus for mandibular condyle fractures, to reduce the risk of postoperative complications and visible scars. Materials and methods Thirty-two patients presenting with mandibular condyle fractures were treated through a modified approach on the edge of the tragus. The age of the patients ranged from 6 to 62 years. All mandibular condyle fractures were fixed. The patients were asked to start open-mouth training one week postoperatively, undergoing a cone-beam computed tomography examination and clinical follow-up. Postoperative complications were evaluated after surgery. Results Mouth opening was normal (average 39.5 mm) in all the patients during the operation and the occlusion improved significantly compared with preoperatively. No cases of damaged facial nerves were observed during the final follow-up at six months and postoperative scars were less noticeable. Conclusions The modified surgical approach from the edge of the tragus for mandibular condyle fractures provides a good view of the operative field, reduces the risk of facial nerve damage and produces a less noticeable postoperative scar.

Abstract
Delay in treating active tuberculosis (TB) impedes disease control by allowing ongoing transmission, and may explain the unexpectedly modest declines in global TB incidence. Even though China has achieved TB control targets under the global Directly Observed Treatment, Short course (DOTS) strategy, TB prevalence in western provinces, including Yunnan, is not decreasing. This cross-sectional study investigates whether prolonged delay in identifying and correctly treating TB patients, which is not routinely monitored, persists even when there is a well-functioning TB control programme and global targets are being met. Records of adult smear-positive pulmonary TB patients diagnosed with between 2006 and 2013 were extracted from the Yunnan Centre for Disease Control electronic database, which contains information on the entire population of TB patients managed across 129 diagnostic centres. Delay was investigated at three stages: delay to DOTS facility (period between symptom onset and first visit to at a CDC unit providing standardized treatment); delay to TB confirmation (period between reaching a CDC unit and confirmation of smear-positive TB) and delay to treatment (period between confirmation of TB and initiation of treatment). Data from 76 486 patients was analysed. Delay to reaching a DOTS facility was by far the largest contributor to total delay to treatment initiation. The median delay to reaching a DOTS facility, to TB confirmation and to treatment was 57 days (IQR 25-112), 2 days (IQR 1-6) and 1 day (IQR 0-1) respectively. Prolonged delays to reaching a facility providing standardized TB care occurred in a substantial subset of the population despite all TB control targets being met; overall, 32% (24 676) of patients experienced a delay of more than 90 days to reaching a DOTS facility. Policies that focus on reducing delays in accessing appropriate health services, rather than only on increasing overall case-detection rates, may result in greater progress towards reducing TB incidence.

Abstract
OBJECTIVES To observe relationships between oral Candida status and salivary human beta-defensin 2 and 3 (hBD-2 and hBD-3) levels in HIV/AIDS patients of Guangxi, China during the first year of antiretroviral therapy (ART) dynamically, and to understand the influence of ART on oral Candida status and salivary hBDs expressions. METHODS A prospective self-controlled study was carried to observe the dynamic changes of CD4+ T cell counts, oral Candida carriages and salivary hBD-2,3 expressions in HIV/AIDS patients during the first year of ART. A total of 90 HIV/AIDS patients were enrolled and were examined at the baseline, 3rd, 6th, 12th month of ART. Thirty healthy individuals were enrolled as control. Peripheral blood, oral rinse sample, and unstimulated whole saliva were collected to test CD4+ T cell counts, oral Candida carriages, and hBD-2,3 expressions. RESULTS In the first year of ART, CD4+ T cell counts increased significantly. However, oral Candida carriages and oral candidiasis decreased significantly, and salivary hBD-2 expressions in HIV/AIDS patients decreased gradually, salivary hBD-3 levels were highly variable. Salivary hBD-2 concentrations were positively related to oral Candida carriages. CONCLUSIONS The incidence of oral candidiasis among HIV/AIDS patients gradually decreased due to the immune reconstruction of ART. Salivary defensins might play an important role in Candida-host interaction in HIV/AIDS patients.

Abstract
In addition to species identification, the volatile components of dalbergia odorifera and dalbergia spp, were investigated by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). Small amounts of powder samples were acquired by drilling from dalbergia, then the volatile components of the powder samples were concentrated by SPME, and separated by AB-FFAP polar capillary GC column. Of all the volatile components, twenty types were identified, and two pairs of them, 2-(1,1-dimethylethyl)-5-heptyl-5-methyl-1,3-dioxolan-4-one and 2,6,10-trimethyl-7,10-epoxy-2,11-dodecadien-6-ol, 2-methylbutylidene-cyclopentane and 2-(5-methyl-furan-2-yl)-propionaldehyde, could be considered specific volatile components for the identification of dalbergia odorifera and dalbergia spp, and the relative contents of these two pairs were compared for the species identification analysis. The method has the advantages of less sample requirement, simple operation, and no construction damage. The method is suitable for the research of volatile components and species identification analysis of dalbergia odorifera and dalbergia spp, and has broad prospective application in the analysis of furniture, art collections and raw wood of dalbergia.

Abstract
Objective: To evaluate the association between the ratio of early diastolic transmitral velocity to early diastolic mitral annular velocity (E/E') and left atrial pressure (LAP) estimated from invasive catheter measurements in patients with atrial fibrillation (AF). Methods: A total of 46 consecutive patients with non-valvular AF and preserved left ventricular ejection fraction (LVEF) admitted in our department to receive the first radiofrequency ablation from May to July 2017 were included. All patients underwent echocardiography at 24-48 hours before radiofrequency ablation, and LAP was invasively measured during the ablation procedure. According to mean LAP, patients were divided into 2 groups of normal LAP (LAP≤12 mmHg(1 mmHg=0.133 kPa, n=31) and elevated LAP (LAP>12 mmHg, n=15). Linear correlation analysis was used to evaluate the relationship between E/E' and LAP. Results: E/E' correlated well with LAP (septal E/E' (E/E'(sep)), r= 0.397, P=0.006; lateral E/E' (E/E'(lat)), r=0.433, P=0.003; mean E/E' (E/E'(mean)), r=0.431, P=0.003). Using receiver operating characteristic analysis, the optimal cut-off for E/E'(sep) was 12.5 (sensitivity 73.3%, specificity 67.7%), E/E'(lat) was 10.8 (sensitivity 80.0%, specificity 77.4%), E/E'(mean) was 11.0 (sensitivity 86.7%, specificity 64.5%) to predict mean LAP>12 mmHg. Conclusion: E/E', especially the E/E'(lat), is positively correlated with LAP in patients with AF and preserved LVEF, and may be used to estimate the diastolic function in AF patients with preserved LVEF.

Abstract
Infection of hepatitis B virus (HBV) occurs in ~10% of infants of HBV-infected mothers with positive hepatitis B e antigen (HBeAg) after immunoprophylaxis. We aimed to evaluate the safety and efficacy of telbivudine used during late pregnancy for preventing mother-to-child transmission of HBV. We conducted a multicenter prospective cohort study in 5 hospitals from 2012 to 2014, which enrolled HBV-infected singleton pregnant women with positive HBeAg. By their choice, women were divided into therapy (telbivudine 600 mg/day, from gestation 28-32 weeks to 3-4 weeks postpartum) and control (no antiviral agent) groups. Infants received passive-active immunoprophylaxis and follow-up at the age of 7-14 months. Totally, 328 pregnant women were included: 149 in the telbivudine group and 179 in the control group. Baseline HBV DNA levels were similar in the 2 groups (7.43 vs 7.37 log10 IU/mL, P = .711). At delivery, HBV DNA levels in the telbivudine and control groups were 3.80 and 7.26 log10 IU/mL, respectively (P < .0001). Of the infants, 128 (85.9%) in the telbivudine group and 156 (87.2%) in the control group were followed up. No infant in the telbivudine group had chronic infection, while 2 (1.28%) infants in the control group did (P = .503). Three (2.34%) infants in the telbivudine group, but none in the control group, had severe congenital or developmental abnormalities (P = .090). The data indicate that telbivudine may block perinatal HBV transmission. However, larger studies are required to clarify whether anti-HBV therapy in pregnancy is associated with severe adverse effects in the foetuses and infants.

Abstract
Late blight, caused by the oomycete pathogen Phytophthora infestans, is the most devastating disease in potato. For sustainable management of this economically important disease, resistance breeding relies on the availability of resistance (R) genes. Such R genes against P. infestans have evolved in wild tuber-bearing Solanum species from North, Central and South America, upon co-evolution with cognate avirulence (Avr) genes. Here, we report how effectoromics screens with Avr2 of P. infestans revealed defense responses in diverse Solanum species that are native to Mexico and Peru. We found that the response to AVR2 in the Mexican Solanum species is mediated by R genes of the R2 family that resides on a major late blight locus on chromosome IV. In contrast, the response to AVR2 in Peruvian Solanum species is mediated by Rpi-mcq1, which resides on chromosome IX and does not belong to the R2 family. The data indicate that AVR2 recognition has evolved independently on two genetic loci in Mexican and Peruvian Solanum species, respectively. Detached leaf tests on potato cultivar 'Désirée' transformed with R genes from either the R2 or the Rpi-mcq1 locus revealed an overlapping, but distinct resistance profile to a panel of 18 diverse P. infestans isolates. The achieved insights in the molecular R - Avr gene interaction can lead to more educated exploitation of R genes and maximize the potential of generating more broad-spectrum, and potentially more durable control of the late blight disease in potato.

Abstract
OBJECTIVE To investigate the effect of decellularized osteochondral extracellular matrix (ECM) scaffold for osteochondral defect regeneration. DESIGN We compared the histological features and microstructure of degenerated cartilage to normal articular cartilage. We also generated and evaluated osteochondral ECM scaffolds through decellularization technology. Then scaffolds were implanted to osteochondral defect in rabbit model. After 12 weeks surgery, regeneration tissues were analyzed by histology, immunohistochemistry evaluation. And possible mechanisms of angiogenesis and cell migration were explored. RESULTS We demonstrated decreased cell numbers, formation of fibrous cartilage, lost microstructure and worse permeability in degenerated cartilage compared to normal cartilage. We also generated an osteochondral ECM scaffold with a hierarchical structure that exhibited low immunogenicity, high bioactivity, and well biocompatibility. We found that the ECM scaffold promoted tissue regeneration in osteochondral defects, which was dependent on the scaffold constituents and stratified three-dimensional microstructure as well as on its ability to inhibit angiogenesis and stimulate cell migration. CONCLUSIONS Our findings demonstrated that the biphasic hierarchical ECM scaffold represents a novel and effective biomaterial that can be used in the treatment of osteochondral defect.

PURPOSES/OBJECTIVES By observing and analyzing the clinical features of the colon cancer and the influence factors of liver metastasis, we try to find out independent risk factors with significant influence on colon cancer liver metastasis as well as to provide reference for clinical treatment. MATERIALS AND METHODS A total of 306 cases of colon cancer patients' clinical data, including gender, age, primary focal size, primary focal intestinal segment, degree of differentiation, infiltration depth, level of serum carcinoembryonic antigen (CEA) before surgery, lymph node metastasis, liver basic diseases were collected and recorded. Single-factor Chi-square analysis and multifactor logistic regression analysis (SPSS 16.0 software) were used to retrospectively study the possible influence factors of colon liver metastases and to preliminary discuss the potential risk factors of liver metastasis in colon cancer patients. RESULTS The Chi-square analysis showed that patients' primary focal segment, degree of differentiation, infiltration depth, level of serum CEA before surgery, and states of hepatitis B does 2 half-and-half had significant effect on the incidence of liver metastasis. However, in the further logistic regression analysis, it showed that only the infiltration depth and the states of hepatitis B does 2 half-and-half were the independent risk factors that influence the hepatic metastases. What was more, the both subgroups of positive hepatitis B with infection and vaccine showed significant statistical differences when comparing with hepatitis B all negative in the event of the probability of liver metastases (P = 0.011 and 0.004). CONCLUSIONS The infiltration depth and the states of hepatitis B does 2 half-and-half were the independent risk factors on colon cancer patients' hepatic metastases. Those with the infiltration depth of T4 had a higher rate of hepatic metastases. Patients with does 2 half-and-half-positive hepatitis B (whether subgroup of hepatitis B virus infection or subgroup hepatitis B vaccine related) had a lower incidence rate of liver metastasis than those with hepatitis B all negative.

Abstract
Background: TP53 and PIK3CA are the most frequently mutated genes in breast cancer. However, there is limited data evaluating the impact of somatic mutations in TP53 and/or PIK3CA patients (pts) with metastatic breast cancer (MBC) who have undergone germline testing for BRCA mutations. Here, we report the frequency of somatic TP53 and PIK3CA mutations in MBC pts who previously underwent germline BRCA (gBRCA) testing and evaluate their impact on long-term outcomes.
Methods: We identified pts with MBC from our prospectively maintained high risk genetics database who underwent gBRCA testing and had somatic mutation testing performed for TP53 and/or PIK3CA through hotspot sequencing of single genes or as part of a next generation sequencing panel. Univariable logistic regression was used to evaluate associations between clinicopathological characteristics, including gBRCA status, and the presence of somatic TP53 and PIK3CA mutations. Overall survival (OS) was defined as the time from diagnosis to death from any cause. Multivariable cox regression analysis was used to identify independent predictors of OS.
Results: 104 pts met all inclusion criteria. Somatic mutations in TP53 and PIK3CA were found in 46% (39/84) and 23% (24/104) of tested pts, respectively. Associations between clinicopathological characteristics and somatic TP53 and PIK3CA mutation status are summarized in Table 1. Pts with hormone receptor positive (HR+) disease were less likely to have TP53 mutations (odds ratio [OR]: 0.28, 95% confidence interval [CI]: 0.11-0.70, p=0.007) but more likely to harbor PIK3CA mutations (OR: 3.27, 95% CI: 1.11-9.62, p=0.031). There were no significant associations between gBRCA mutation status and somatic TP53 or PIK3CA mutations. On multivariable analysis, somatic TP53 mutations (adjusted hazard ratio [aHR]: 1.98, 95% CI: 1.10-3.58, p=0.023) and de novo metastatic disease (aHR=2.88, 95% CI: 1.26-6.58, p=0.012) independently predicted poorer OS, while HR+ disease (aHR: 0.40, 95% CI: 0.21-0.74, p=0.004) and HER2+ disease (aHR: 0.33, 95% CI: 0.13-0.83, p=0.019) were significantly associated with improved OS. PIK3CA mutations (aHR: 1.20, 95% CI: 0.59-2.44, p=0.62) and gBRCA mutations (aHR: 0.78, 95% CI: 0.33-1.83, p=0.57) did not significantly impact OS in this study.
Conclusion: In this study, somatic TP53 mutations independently predicted worse OS in pts with MBC after adjusting for significant covariates, including gBRCA mutation status. These findings should be validated in a larger cohort of pts.

Abstract
Dry eye is one of the most common ocular problems in ophthalmology clinic. With the change of social environment and people's life style, the prevalence of dry eye disease is increasing. Currently, the diagnosis criteria for dry eye is controversial, diagnosis of dry eye mainly rely on the comprehensive assessment of symptoms and the presence of associated ocular surface signs. However, previous studies have shown a poor correlation between dry eye symptoms and objective clinical signs in patients. Recent studies have found that neuropathic pain plays an important role in the occurrence of discordance between symptoms and signs in dry eye disease. The purpose of this paper is to present the conception of pain, the distribution and function of sensory nerves in ocular surface, the prevalence and mechanism of neuropathic pain and analgesic treatment in dry eye disease.

Abstract
Ninety sex pheromone biosynthesis genes in Spodoptera litura were identified in transcriptome data and were investigated and classified into the following five groups: fatty acid synthase, beta oxidase, fatty acyl-coenzyme A (CoA) reductase, desaturase and acetyl-CoA acetyltransferase. Fourteen female-specific genes were identified through semi-quantitative PCR, and 15 additional genes had expression levels that were 3- to 10-fold higher in females than in males. The majority of the genes had higher expression levels in the sex pheromone glands. Injection of double-stranded RNA (dsRNA) against nine selected genes showed that down-regulation of Desaturase 3 (Des3), Des5 or fatty acyl coenzyme A reductase 17 (FAR17) significantly changed the ratio of the four sex pheromone components (Z,E) -9,11-tetradecadienyl acetate (Z9E11-14:Ac), (Z,E)-9,12-Tetradecadienyl acetate(Z9E12-14:Ac), (Z)-9-tetradecenyl acetate (Z9-14:Ac), (E)-11-Tetradecenyl acetate(E11-14:Ac). These key genes were differentially expressed in female moths collected from different geographical regions. Furthermore, field bioassays demonstrated geographical variation in the olfactory profile of male moths in response to the different sex pheromone mixtures, which therefore indicates that a significant variation in the sex pheromone components exists in the natural population. Our results suggest that a change in the expression of these key genes, Des3, Des5 and FAR17, in the sex pheromone biosynthesis pathway could change the ratio of the sex pheromone components. We surmise that the differential expression levels of the key genes of the sex pheromone biosynthesis pathway may lead to differential ratios of the sex pheromones in the field. Our field trapping experiment suggested that the change of the ratio of the sex pheromone components may have been adapted by the olfactory system and possibly mediate olfactory plasticity in conspecific male moths.

Abstract
Large-scale knowledge bases, as the foundations for promoting the development of artificial intelligence, have attracted increasing attention in recent years. These knowledge bases contain billions of facts in triple format; yet, they suffer from sparse relations between entities. Researchers proposed the path ranking algorithm (PRA) to solve this fatal problem. To improve the scalability of knowledge inference, PRA exploits random walks to find Horn clauses with chain structures to predict new relations given existing facts. This method can be regarded as a statistical classification issue for statistical relational learning (SRL). However, large-scale knowledge base completion demands superior accuracy and scalability. In this paper, we propose the path feature learning model (PFLM) to achieve this urgent task. More precisely, we define a two-stage model: the first stage aims to learn path features from the existing knowledge base and extra parsed corpus; the second stage uses these path features to predict new relations. The experimental results demonstrate that the PFLM can learn meaningful features and can achieve significant and consistent improvements compared with previous work.

Abstract
BACKGROUND Patients with port-wine stain (PWS) suffer physically and psychologically because of the high incidence (0.3%-0.5%) of the disease. Pulsed-dye laser (PDL) at 595 nm is the gold standard of the treatment for PWS. Nevertheless, clinicians intend to determine whether the dual-wavelength laser (DWL; 595-nm PDL + 1064-nm Nd:YAG) is an adequate choice in the treatment of non-treated PWS. This study is the first prospective within-patient controlled research seeking to investigate the safety and efficacy of DWL for the treatment of non-treated PWS. METHODS A total of 61 patients with non-treated flat facial PWS, who were treated using the Cynergy laser system in our clinic, were included in this study. Each PWS lesion was divided into two adjacent test treatment sites of similar size and colour. The two sites were randomly assigned to PDL or DWL treatment in a blinded manner of participants. In each case, two sets of treatment parameters were used: (i) 595-nm PDL and (ii) 595-nm PDL + 1064-nm Nd:YAG. Both had a 10 mm spot size, an epidermal cooling system and 1-s interpulse interval between two pulses. Clinical efficacy and safety outcomes were evaluated by visual assessment 2 months after treatment. RESULTS Comparison by visual evaluation suggests that the responses of non-treated PWS to treatment by PDL and DWL were not significantly different. Moreover, three patients developed scarring after DWL treatment. CONCLUSION Compared with PDL, DWL exhibits a higher risk of potential scarring and has no advantage in efficacy of treating non-treated PWS.

Abstract
Testicular torsion is a urology urgent disease which causes testicular injury and potential sterility. In this study, we explored the protective influence of rosiglitazone on testicular ischaemia-reperfusion damage. There were 28 male Sprague Dawley rats in total, which were assigned randomly to four groups. Group A was blank control one; group B was testicular injury one; group C was rosiglitazone one; group D was rosiglitazone antagonist one. The testicles were counter-rotated after 2 hr and then underwent orchiectomy 24 hr later. We found that testicular tissue structure of rats was seriously damaged in groups B and D. However, group C had better testicular architecture. Similar findings were also shown for lipid peroxidation by evaluating the MDA activity (p < .05). Unlike group B or group D, the levels of inflammation by evaluating the MPO activity, the levels of TNF-a, IL-1 and IL-6 and the expressions of ICAM-1 were prominently lower in group C (p < .05) as well. So our researches demonstrated that rosiglitazone significantly decreased the amount of responsive oxygen radical and regulated inflammatory responses. Rosiglitazone had a protective influence against testicular ischaemia-reperfusion injury in rats and possibly depended on its anti-inflammatory and antioxidant traits.

Abstract
Objective: The study was designed to evaluate the effect of follicular fluid from patients with endometriosis, follicle stimulating hormone (FSH), bone morphogenetic protein 15 (BMP-15) on the proliferation and progesterone secretion of human luteinized granular cells in vitro. Methods: Cumulus granulosa cells were collected from the patients who underwent in vitro fertilization and embryo transfer (IVF-ET) ovulation due to tubal or male factor infertility on the day of the retrieval. The cells in the control group were cultured with complete medium of DMEM/F-12, an extra of FSH at a dose of 12 μg/L was added in the FSH group, an extra of BMP-15 at a dose of 6 μg/L was added to the BMP-15 group, an extra of 5% of the follicular fluid from the patients with tubal or male factor infertility was added to the tubal group, an extra of 5% of the follicular fluid from the patients with endometriosis infertility was added to the endometriosis group, an extra of 5% of the follicular fluid from the patients with endometriosis infertility plus FSH at a dose of 12 μg/L were added to the endometriosis plus FSH group, and an extra of 5% of the follicular fluid from the patients with endometriosis infertility plus BMP-15 at a dose of 6 μg/L were added to the endometriosis plus BMP-15 group. Hemacytometer counting method was used to observe the growth of cells after 48 hours, and chemiluminescence method was utilized to measure the level of progesterone in culture supernatant. Results: The cell proliferation was enhanced in the FSH group, while the proliferation was inhibited in the endometriosis group and the endometriosis plus BMP-15 group, compared to the control group, both of which, were statistically significant. Compared to the control group, the progesterone levels from the culture supernatant of granular cells were significantly elevated in the FSH group, tubal group and endometriosis group. The secretion of progesterone in the endometriosis group was lower than that in the tubal group. After addition of FSH into the endometriosis group (the endometriosis plus FSH group), the secretion level of progesterone was significantly increased, compared to the control group and the endometriosis group. After adding BMP-15 into the endometriosis group (the endometriosis plus BMP-15 group), the secretion level of progesterone was increased, compared to the control group. Conclusions: FSH, but not BMP-15, was able to enhance the proliferation and progesterone secretion of granular cells. The proliferation of granular cells and secretion of progesterone were inhibited by the follicular fluid from patients with endometriosis, which was reversed by FSH. However, BMP-15 had no effect on the outcome of follicular fluid from patients with endometriosis.

Abstract
Cascading failures are a critical vulnerability of complex information or infrastructure networks. Here we investigate the properties of load-based cascading failures in real and synthetic spatially-embedded network structures, and propose mitigation strategies to reduce the severity of damages caused by such failures. We introduce a stochastic method for optimal heterogeneous distribution of resources (node capacities) subject to a fixed total cost. Additionally, we design and compare the performance of networks with N-stable and (N-1)-stable network-capacity allocations by triggering cascades using various real-world node-attack and node-failure scenarios. We show that failure mitigation through increased node protection can be effectively achieved against single-node failures. However, mitigating against multiple node failures is much more difficult due to the combinatorial increase in possible sets of initially failing nodes. We analyze the robustness of the system with increasing protection, and find that a critical tolerance exists at which the system undergoes a phase transition, and above which the network almost completely survives an attack. Moreover, we show that cascade-size distributions measured in this region exhibit a power-law decay. Finally, we find a strong correlation between cascade sizes induced by individual nodes and sets of nodes. We also show that network topology alone is a weak predictor in determining the progression of cascading failures.

Abstract
BACKGROUND Clinical research has shown that sublingual immunotherapy (SLIT) is effective and safe in moderate-severe allergic rhinitis (AR) induced by house dust mite (HDM). However, the sample size in many studies is small. Meanwhile, the controversy on the efficacy and safety in the very young children younger than four years old still existed. OBJECTIVE The aim of this retrospective study is to evaluate the efficacy and safety of SLIT with Dermatophagoides farinae (Der.f) extracts in children and adult patients with allergic rhinitis, particularly in the very young children. METHOD A total of 573 subjects aged 3-69 with AR received a three-year course of sublingual immunotherapy with Der.f extracts along with pharmacotherapy. The total nasal symptoms score (TNSS), total medication score (TMS), visual analogue score (VAS) and adverse events (AEs) were evaluated at each visit. RESULT TNSS, TMS, VAS were significantly improved during the three-year course of treatment in comparison to the baseline values (P<0.01). Besides, significant improvement in nasal symptoms and reduction of medication use were also observed in young children aged 3-6 years (P<0.01). No severe systemic adverse events (AEs) were reported. CONCLUSION SLIT with Der.f drops is clinically effective and safe in children and adult patients with HDM-induced AR, including the very young children less than four years old.

Abstract
Uveitis (intraocular inflammation) is a leading cause of loss of vision. Although its aetiology is largely speculative, it is thought to arise from complex genetic-environmental interactions that break immune tolerance to generate eye-specific autoreactive T cells. Experimental autoimmune uveitis (EAU), induced by immunization with the ocular antigen, interphotoreceptor retinoid binding protein (IRBP), in combination with mycobacteria-containing complete Freund's adjuvant (CFA), has many clinical and histopathological features of human posterior uveitis. Studies in EAU have focused on defining pathogenic CD4+ T cell effector responses, such as those of T helper type 17 (Th17) cells, but the innate receptor pathways precipitating development of autoreactive, eye-specific T cells remain poorly defined. In this study, we found that fungal-derived antigens possess autoimmune uveitis-promoting function akin to CFA in conventional EAU. The capacity of commensal fungi such as Candida albicans or Saccharomyces cerevisae to promote IRBP-triggered EAU was mediated by Card9. Because Card9 is an essential signalling molecule of a subgroup of C-type lectin receptors (CLRs) important in host defence, we evaluated further the proximal Card9-activating CLRs. Using single receptor-deficient mice we identified Dectin-2, but not Mincle or Dectin-1, as a predominant mediator of fungal-promoted uveitis. Conversely, Dectin-2 activation by α-mannan reproduced the uveitic phenotype of EAU sufficiently, in a process mediated by the Card9-coupled signalling axis and interleukin (IL)-17 production. Taken together, this report relates the potential of the Dectin-2/Card9-coupled pathway in ocular autoimmunity. Not only does it contribute to understanding of how innate immune receptors orchestrate T cell-mediated autoimmunity, it also reveals a previously unappreciated ability of fungal-derived signals to promote autoimmunity.

Abstract
Undercarboxylated osteocalcin (ucOC) may play a role in glucose homeostasis and cardiometabolic health. This review examines the epidemiological and interventional evidence associating osteocalcin (OC) and ucOC with metabolic risk and cardiovascular disease. The complexity in assessing such correlations, due to the observational nature of human studies, is discussed. Several studies have reported that higher levels of ucOC and OC are correlated with lower fat mass and HbA1c. In addition, improved measures of glycaemic control via pharmacological and non-pharmacological (e.g. exercise or diet) interventions are often associated with increased circulating levels of OC and/or ucOC. There is also a relationship between lower circulating OC and ucOC and increased measures of vascular calcification and cardiovascular disease. However, not all studies have reported such relationship, some with contradictory findings. Equivocal findings may arise because of the observational nature of the studies and the inability to directly assess the relationship between OC and ucOC on glycaemic control and cardiovascular health in humans. Studying OC and ucOC in humans is further complicated due to numerous confounding factors such as sex differences, menopausal status, vitamin K status, physical activity level, body mass index, insulin sensitivity (normal/insulin resistance/T2DM), tissue-specific effects and renal function among others. Current observational and indirect interventional evidence appears to support a relationship between ucOC with metabolic and cardiovascular disease. There is also emerging evidence to suggest a direct role of ucOC in human metabolism. Further mechanistic studies are required to (a) clarify causality, (b) explore mechanisms involved and

Abstract
OBJECTIVE Body's iron metabolism is at one dynamic balance status, and abnormal iron metabolism may lead to renal anemia. Inflammation stimuli may lead to abnormal iron metabolism and aggravation of chronic failure anemia. Hepcidin can regulate iron metabolic homeostasis, further mediating renal anemia. Interleukin-10 (IL-10) is an inflammatory inhibitor, but with an unclear function in the regulation of hepcidin expression. MATERIALS AND METHODS BALB/c mice were randomly assigned into three groups: control group; lipid polysaccharide (LPS) group, which received 0.1 mg/kg LPS via tail veins; IL-10 group with 0.2 mg/kg IL-10 injection after LPS. Red blood cell count (RBC), hemoglobulin (Hb), hematocrit (HCT), mean corpuscular volume (MCV) and iron content in hemoglobulin were measured. Real-time PCR quantified hepcidin mRNA expression in all groups. Enzyme linked immunosorbent assay (ELISA) tested serum hepcidin, IL-6 and tumor necrosis factor-α (TNF-α) levels. Western blot analyzed expression of mouse transferrin receptor 2 (TfR2) and hepcidin signal pathway molecule STAT3. RESULTS LPS model group had lower RBC, Hb, HCT, MCV and iron content in Hb, plus elevated hepcidin, IL-6, TNF-α, TfR2 and STAT3 expression (p < 0.05 compared to the control group). IL-10 treatment group significantly facilitated RBC, Hb, HCT, MCV and Hb iron contents in LPS-induced inflammatory model mice, which also had lower hepcidin, IL-6, TNF-α, TfR2 or STAT3 expression (p < 0.05 compared to LPS group). CONCLUSIONS IL-10 can improve iron metabolism and alleviate anemia via suppressing inflammatory factor, modulating STAT3 signal pathway, down-regulating hepcidin expression and inhibiting TfR expression.

Abstract
OBJECTIVES The aim was to compare the osteoblast activity and osteogenic potential of autogenous bone particles harvested using three different techniques and determine the most advantageous method of collecting autogenous bone particles. SUBJECTS AND METHODS Bone particles were harvested from 20 patients during dental implant surgery using bone scraping, low-speed drilling and bone trap filtering. After the osteoblasts were cultured, cell proliferation, migration, mineralization, transcription of osteogenesis-related genes, secretion of osteogenesis-related proteins and osteoinductive protein content in the bone particle matrix were evaluated. RESULTS Osteoblast activity and osteogenic potential were higher in bone samples harvested by scraper or low-speed drilling than in samples harvested by bone trap filter. Although these parameters were slightly lower in the low-speed drilling group than in the scraper group, significant differences were found only in bone Gla protein levels. However, the levels of osteoinductive proteins in the bone particle matrix were significantly higher in the low-speed drilling group than in the scraper group. CONCLUSIONS Low-speed drilling is a recommendable and effective technique for collecting autogenous bone particles. In implant operations, low-speed drilling can be considered the first-line option, and if the quantity of harvested bone is insufficient, bone shavings obtained by the scraper may be considered.

Abstract
Two-dimensional (2D) materials have been studied extensively as monolayers, vertical or lateral heterostructures. To achieve functionalization, monolayers are often patterned using soft lithography and selectively decorated with molecules. Here we demonstrate the growth of a family of 2D materials that are intrinsically patterned. We demonstrate that a monolayer of PtSe2 can be grown on a Pt substrate in the form of a triangular pattern of alternating 1T and 1H phases. Moreover, we show that, in a monolayer of CuSe grown on a Cu substrate, strain relaxation leads to periodic patterns of triangular nanopores with uniform size. Adsorption of different species at preferred pattern sites is also achieved, demonstrating that these materials can serve as templates for selective self-assembly of molecules or nanoclusters, as well as for the functionalization of the same substrate with two different species.

Abstract
Objective:To explore the expression and clinical significance of nuclear factor erythroid-2 related factor 2 (Nrf2) and ERK sinal in papillary thyroid carcinoma (PTC). Method:PTC microassy were detected by immunohistochemical method (IHC). The expression of Nrf2, ERK₂ and p-ERK½ in PTC, para-carcimoma and normal thyroid tissue were detected by Western blot. The transcriptional level of Nrf2 mRNA in PTC, para-carcimoma and normal thyroid tissue were detected by real-time quantitative PCR (qPCR) method. Result:Nrf2, ERK₂, p-ERK½ protein were high expression in group of lymph node metastasis PTC and negative or weak positive expression in para-carcinoma tissue (P<0.01). And the proteins of clinical stage Ⅲ-Ⅳ of PTC groups express higher than without lymph node metastasis group and clinical stage Ⅰ-Ⅱ of PTC group (P<0.05). The expression of Nrf2 protein was positively correlated with ERK₂ and p-ERK½ protein in PTC (r=0.723 2,r=0.668 6,P<0.05). The Western blot results of Nrf2, ERK₂, p-ERK½ had a higher level in PTC than those of paracarcinoma and normal thyroid tissue (P<0.01). The level of Nrf2 mRNA were higher than those of paracarcinoma and normal thyroid tissue (P<0.01). Conclusion:High expresion of Nrf2 may be associated with the progression of papillary thyroid carcinoma, and may relate to the high expression and activity of ERK pathway.

Abstract
OBJECTIVE We evaluated the efficacy of surfactant therapy and assisted ventilation on morbidity and mortality of neonates with birth weight (BW) ⩾1500 g and hypoxemic respiratory failure (HRF). STUDY DESIGN We retrospectively analyzed 5650 patients with BW ⩾1500 g for incidence, management and outcome of HRF, defined as acute hypoxemia requiring mechanical ventilation and/or nasal continuous positive airway pressure ⩾24 h. The patients were allocated into groups of moderate preterm (1735, 30.7%), late preterm (1431, 25.4%), early term (ETM, 986, 17.5%), full term (1390, 24.6%) and post term (79, 1.4%), with gestational age ⩽33, 34 to 36, 37 to 38, 39 to 41 and ⩾42 weeks, respectively. RESULTS In the five groups, 66.9, 42, 21.6, 12.8 and 5.1% had respiratory distress syndrome (RDS). For pneumonia/sepsis and meconium aspiration syndrome (MAS), the proportion was 13.8%, 25.4%, 38.0%, 52.5% and 76.0%, respectively. Surfactant was given to 21.9% (n=1238) of HRF and 51.2% (n=1108) of RDS. Survival rates of RDS were 82.2%, 87.8%, 84.5%, 77.1% and 75.0%, respectively (numbers needed to treat was 8 to 11 for surfactant benefit). Overall mortality rate of HRF was 21%, or 17.9%, 14.7%, 25.6%, 28.9% and 39.2%, respectively. Mortalities of MAS and pneumonia/sepsis were 29.4 and 27.6%. Relative risk of death was associated with initial disease severity, female gender, mechanical ventilation and congenital anomalies by multivariate logistic regression analysis. CONCLUSION Surfactant was effective for infants with RDS and BW ⩾1500 g, and different incidences and outcome of HRF among GA groups reflected standard of perinatal and respiratory care in emerging neonatal intensive care unit network.
