Abstract
UNLABELLED Despite the high costs of hip fracture, many governments provide limited support for osteoporosis screening. We demonstrated that osteoporosis screening by dual-energy X-ray absorptiometry (DXA) with or without pre-screening by Fracture Risk Assessment Tool (FRAX) or calcaneal ultrasound are more cost-effective than no screening in Chinese people aged 65 or over in Hong Kong. INTRODUCTION To examine the cost-effective potential osteoporosis screening strategies for hip fracture prevention in Hong Kong. METHODS Decision tree models were constructed to evaluate the cost per quality-adjusted life years (QALYs) of the different osteoporosis screening strategies followed by subsequent 5-year treatment with alendronate compared to no screening (but treat if a hip fracture occurs). The multiple osteoporosis screening strategies were composed of alternative tests and initiation age groups were evaluated with a 10-year horizon, and treatment were assigned if central dual-energy X-ray absorptiometry (DXA) T-score (at either the hip or spine) is - 2.5 or less. Strategies included DXA for all people and pre-screening with the Fracture Risk Assessment Tool (FRAX) at specific thresholds or by calcaneal quantitative ultrasonography (QUS) before taking DXA examination. All the model inputs were based on the Mr. OS and Ms. OS Hong Kong cohort; data are obtained from the Social Welfare Department or the published literature. RESULTS All of the screening strategies, including the universal screening with DXA and the pre-screening with FRAX or QUS before DXA, were consistently more cost-effective than no screening for people aged 65 years old or over. One-way sensitivity analysis with a more optimistic assumption on treatment adherence or inclusion of other major osteoporotic fractures did not change the results materially. Probabilistic sensitivity analyses showed a dominant role of pre-screening with FRAX followed by subsequent osteoporosis drug treatment in people aged 70 years old or over in Hong Kong. CONCLUSIONS Osteoporosis screening strategies based on DXA with or without pre-screening are more cost-effective compared to no screening for Chinese people aged 65 or over in Hong Kong.

Abstract
Abstract
Lung cancer kills more people in the United States than any other malignancy. High mortalities are in part due to the diagnosis at an advanced inoperable stage where the 5-year survival is only 4%. Therefore, improving survival will require increased knowledge of genes that drive the complex mechanisms of lung cancer initiation and progression. Emerging data implicate novel roles for protein arginine methylation in lung cancers. In protein arginine methylation, nitrogen/s of arginine can be post-translationally modified via the addition of a methyl group, catalyzed by a class of enzymes, protein arginine methyl transferases (PRMTs). Based on the computational analysis, tissue staining, and immunoblotting we have identified an increased expression of PRMT6 in lung tumors. To test the biologic relevance of PRMT6 in lung tumor development, we employed an inducible lung-targeted PRMT6 gain-of-function (GOF) mouse model. For the first time, we show that lung-targeted overexpression of PRMT6 results in spontaneous lung tumor development. We also observed a robust increase in lung tumors in the PRMT6 GOF mice in response to urethane, a KRas mutagen, and a prototypical model to study lung tumorigenesis. Excitingly, we detected an increase in the number of tumor-associated macrophages (TAMs) in the PRMT6 GOF mice. Further characterization of the TAMs from the PRMT6 GOF mice revealed that they were M2 polarized with immunosuppressive, angiogenesis-enhancing, and tumor-promoting activities. Taken together, these results demonstrate a novel role for PRMT6 in lung tumor development by way of macrophage M2 polarization. Therefore, defining the complete mechanism of PRMT6-mediated macrophage M2 polarization could lead to the development of novel therapeutic strategies to treat lung cancer.

Abstract
Abstract
Background: Lung cancer is the second most common cancer diagnosed in women. In fact, twice as many women will die from lung cancer compared to breast cancer, the key risk factor being tobacco use. Hence, there is a need to identify new molecular biomarkers to aid in early detection and develop new therapeutic strategies in tobacco-related lung cancer. Ras-like Estrogen-Regulated Growth-Inhibitory Gene (RERG) is a member of the Ras superfamily of GTPases that play an important role in cellular processes such as proliferation, differentiation, and apoptosis. Unlike other members of the Ras superfamily members of proto-oncogenes, RERG functions as a tumor suppressor.
Objective: To investigate the utility of RERG expression as a novel biomarker and a potential therapeutic target in lung cancer.
Results: In silico analysis of The Cancer Genome Atlas (TCGA) lung cancer datasets revealed a significant downregulation of RERG expression in lung tumors. Furthermore, reduced expression of RERG in lung tumors was also observed to be correlated with poor prognosis as determined by Kaplan-Meier survival analysis. Evaluation of formalin-fixed, paraffin-embedded (FFPE) human lung cancer tissues and fresh frozen lung tumor tissues corroborated our in silico observations. Most notably, tobacco smoke was identified to be associated with decreased RERG expression in lung tumors. The most intriguing observation from this study is the significant decrease of RERG expression in female smokers as a result of promoter hypermethylation.
Conclusion: Taken together, these findings suggest that RERG may represent a potential biomarker in lung cancer, particularly among smokers. Further investigation would focus on the mechanism of RERG loss and its influence on lung tumor development, particularly in female smokers.

Abstract
Usually, mapping studies in potato are performed with segregating populations from crosses between highly heterozygous diploid or tetraploid parents. These studies are hampered by a high level of genetic background noise due to the numerous segregating alleles, with a maximum of eight per locus. In the present study, we aimed to increase the mapping efficiency by using progenies from diploid inbred populations in which at most two alleles segregate. Selfed progenies were generated from a cross between S. tuberosum (D2; a highly heterozygous diploid) and S. chacoense (DS; a homozygous diploid clone) containing the self-incompatibility overcoming S locus inhibitor (Sli-gene). The Sli-gene enables self-pollination and the generation of selfed progenies. One F2 population was used to map several quality traits, such as tuber shape, flesh and skin color. Quantitative trait loci were identified for almost all traits under investigation. The identified loci partially coincided with known mapped loci and partially identified new loci. Nine F3 populations were used to validate the QTLs and monitor the overall increase in the homozygosity level.

Abstract
Traumatic spinal cord injury (SCI) causes permanent disability to at least 180,000 people per year worldwide. Early regulation of spinal fibroblast proliferation may inhibit fibrotic scar formation, allowing the creation of a favorable environment for neuronal regeneration and thereby enhancing recovery from traumatic SCIs. In this study, we aimed to identify the role of microRNA-21a-5p (miR-21a-5p) in regulating spinal fibroblasts after mechanical trauma and to investigate the dysregulation of miR-21a-5p in the pathological process of spinal SCI. We investigated the differential expression of microRNAs in primary spinal fibroblasts after mechanical trauma and found that the expression of miR-21a-5p was higher in spinal fibroblasts after scratch damage (SD). In addition, mouse spinal fibroblasts were transfected with miR-21a-5p mimics/inhibitor, and the role of miR-21a-5p in spinal fibrogenic activation was analyzed. These experiments demonstrated that miR-21a-5p overexpression promoted fibrogenic activity in spinal fibroblasts after mechanical trauma, as well as enhancing proliferation and attenuating apoptosis in spinal fibroblasts. Finally, the potential role of miR-21a-5p in regulating the Smad signaling pathway was examined. MiR-21a-5p activated the Smad signaling pathway by enhancing Smad2/3 phosphorylation. These results suggest that miR-21a-5p promotes spinal fibrosis after mechanical trauma. Based on these findings, we propose a close relationship between miR-21a-5p and spinal fibrosis, providing a new potential therapeutic target for SCI.

Abstract
Falls are a major concern in terms of fracture risk. Although awareness rising for the absence of falls in the FRAX algorithm, our study only identified the independent predictive role of previous recurrent falls and their better conjunction use with FRAX for major osteoporotic fracture prediction in older Chinese men.

Abstract
To study the curative effects and safety for patients who adopt both gefitinib and platinum-based chemotherapy or only platinum-based chemotherapy in the treatment of lung adenocarcinoma, 80 EGFR mutation-positive lung adenocarcinoma patients in stage IIIB/IV were divided into two groups. Half of them received both gefitinib and standard chemotherapy (group A), and the others (group B) received only standard chemotherapy. Overall response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and the related toxicities of both groups were recorded in order to take certain nursing measures for a variety of toxicities. Next, statistical methods were used to analyze the curative effects and safety of the two treatments. The results showed that ORR, DCR and median progression-free (mPFS) survival of the two groups of patients showed no statistical difference (P >0.05). However, group A (18.56 months) had a longer median overall survival (mOS) than group B (14.87 months), which was of statistical significance (P less than 0.05). Nausea and loss of appetite were common mild adverse reactions, and anemia and leukocytopenia were moderate common adverse reactions. The difference between these two groups of patients regarding adverse reactions was not statistically significant (P>0.05). In conclusion, the two treatments have similar safety, but lung adenocarcinoma patients with drug resistance during stage IIIB/IV after using first-line gefitinib therapy have lower survival benefits than patients who take both gefitinib and platinum-based chemotherapy.

Abstract
1. This experiment investigated the anti-apoptosis effects and the mechanism of aspirin action in the heat shock response of chicken myocardial cells in vivo, via changes in the heat stress (HS) protein Hsp90 and the rate of apoptosis. Broiler chickens were administered aspirin (1 mg/kg body weight) 2 h before exposure to HS, and then exposed to 40 ± 1°C for 0, 1, 2, 3, 5, 7, 10, 15 and 24 h. 2. The induction and consumption of the HS factor heat shock factor (HSF)-1, and reductions of HSF-2 and HSF-3 induced by HS led to a delay in Hsp90 expression. HSF-1, 2 and 3 regulation of hsp90 expression in turn inhibited the synthesis and activation of protein kinase β (Akt), which resulted in a significant increase in caspase-3 at 2 and 10 h, caspase-9 from 1 to 7 h (except at 5 h), and the heat-stressed apoptosis of the myocardial cells. 3. Administration of aspirin changed the expression patterns of HSF-1, 2 and 3 such that the expression of Hsp90 protein was significantly upregulated (by 2.3-4.1 times compared with that of the non-treated cells). The resultant increase in Akt expression and activation, compared with the HS group, inhibited caspase-3 and caspase-9 activities and reduced the myocardial cells apoptosis rate (by 2.14-2.56 times). 4. Aspirin administration could inhibit heat-stressed apoptosis of myocardial cells in vivo and may be closely associated with its promotion of HS response of chicken hearts, especially Hsp90 expression.

Abstract
Objective: To compare the methylation profiles in tissues of oral leukoplakia (OLK) and oral squamous cell carcinoma (OSCC) with healthy tissues of oral mucosa, in order to identify the role of DNA methylation played in tumorigenesis. Methods: DNA samples extracted from tissues of 4 healthy oral mucosa, 4 OSCC and 4 OLK collected from patients of the Department of Oral Medicine, Capital Medical University School of Stomatology were examined and compared using Methylation 450 Bead Chip. The genes associated with differentially methylated CpG sites were selected for gene ontology (GO) analysis and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment. Results: Multiple differentially methylated CpG sites were identified by using the above mentioned assay. Hypermethylation constitutes 86.18% (23 290/27 025) of methylation changes in OLK and hypomethylation accounts for 13.82% (3 734/27 025) of methylation changes. Both hypermethylated and hypomethylated CpG sites were markedly increased in OSCC tissue compared with OLK tissue. The majority of differentially methylated CpG sites were located outside CpG islands, with approximately one-fourth in CpG shores flanking the islands, which were considered highly important for gene regulation and tumorigenesis. Pathway analysis revealed that differentially methylated CpG sites in both OLK and OSCC patients shared the same pathway enrichments, most of which were correlated with carcinogenesis and cancer progression (e.g., DNA repair, cell cycle, and apoptosis). Conclusions: In the present study, methylation-associated alterations affect almost all pathways in the cellular network in both OLK and OSCC. OLK and OSCC shared similar methylation changes whether in pathways or genes, indicating that epigenetically they might have the same molecular basis for disease progression.

Abstract
OBJECTIVE The purpose of this study was to assess the gelation and polymerization time of three polyvinyl siloxane (PVS) putty materials and to determine if those times were affected by nitrile gloves under different conditions. MATERIALS AND METHODS Ten specimens (n=10) were obtained for each PVS putty material (Express STD, 3M ESPE; Extrude Xtra, Kerr and Exafast, GC) and tested under different conditions (gloves washed, gloves unwashed and hands contaminated). The gelation and polymerization time were measured using an oscillating rheometer and recorded for 400 s at 37°C to simulate the oral environment. RESULTS The mean gelation time of hand contaminated specimens was 157.50 minutes and was significantly slower than that by using nitrile washed gloves (mean=117.94, p=.004) and by using unwashed gloves (mean=99.46, p⟨0.001). Unwashed gloves had significantly quicker gelation times compared to washed gloves (p=.046). The gelation time was significantly delayed with Exafast compared to Extrude Xtra and Express STD across all the different types of glove conditions (p⟨0.043). No significant differences were observed between polymerization time with Exafast and Extrude Xtra Putty. CONCLUSIONS Extrude Xtra putty material had significantly better performance than GC Exafast and Express. Hand contaminated specimens were affected by the gelation/polymerization time.

Abstract
MicroRNAs (miRNAs) are a class of small non-coding RNA molecules that play important roles in carcinogenesis and tumor progression. Previous studies have revealed that MicroRNA-140-5p (miR-140-5p) was abnormally expressed in several cancers. However, its function and possible mechanism in cervical cancer (CC) remains unknown. In this study, the data mining results showed that miR-140-5p was down-regulated in CC specimens and the down-regulation of miR-140-5p was associated with CC poor prognosis. These observations prompted us to further investigate the roles and mechanisms of miR-140-5p in human CC pathogenesis. We found that the over-expression/inhibition of miR-140-5p significantly decreased/increased cell proliferation, migration, and invasion in CC cells in vitro. Meanwhile, the results from in vivo assays showed that the over-expression of miR-140-5p induced significantly suppression of tumor growth and metastasis in nude mice. Furthermore, Insulin like growth factor 2 mRNA binding protein 1 (IGF2BP1) was identified as a direct target of miR-140-5p, and both gain-of-function and loss-of-function assays revealed that IGF2BP1 is also a functional target of miR-140-5p. Taken together, our findings suggested a novel miR-140-5p-IGF2BP1 regulatory circuit for CC pathogenesis, and miR-140-5p may be a potential target for CC therapy.

Abstract
Abstract
Background
Long non-coding RNAs (lncRNAs) have been proved to play an essential role in cancer metastasis. The accuracy of intraoperative assessment of lymph nodes metastasis need to be improved. In this study, we aimed to define the lncRNA biomarker ectopic expressed in breast cancer patients' metastatic lymph nodes, and to explore the potential molecular mechanisms.
Experimental Design
RNA-seq analyses in 3 paired breast cancer patients' primary tumor and metastatic lymph node was used as training set to determine differentially expressed lncRNAs that may be associated with lymph node metastasis. The other 40 patients were analyzed as validation set to test the accuracy of lncRNAs identification by quantitative real-time PCR. The correlation between LOC283299 expression level and prognosis in other 282 breast cancer patients was confirmed. In parallel, in vitro and in vivo analyses were carried out to determine the potential mechanisms of LncRNA-dependent lymph node metastases and prognosis.
Results
RNA-seq analyses in the training set revealed significant correlation between high expression level of LOC283299 and lower lymph node metastasis potential in breast cancer patients. We further validated that the expression level of LOC283299 was significantly higher in tumor primary tissue than that in paired metastatic lymph node (P=0.0245), and higher LOC283299 expression level was markedly associated with good metastasis-free survival in breast cancer patients (P=0.04). In breast cancer cell lines, CRISPR-on overexpression of LOC283299 inhibited proliferation, migration, invasion, and metastases both in vivo and in vitro. shRNA knockdown LOC283299 promotes the ability of tumor proliferation and metastasis. The molecular mechanisms by which LOC283299 as metastasis-suppressing lncRNAs regulates recurrence and metastasis may involve regulation of epithelial to mesenchymal transition (EMT), cellular invasion and microenvironment in breast cancer cells.
Conclusion
Our study revealed a strong correlation between LOC283299 expression and lymph node metastases in breast cancers. High level of LOC283299 was associated with better metastasis-free survival. The changed metastasis phenotype may be mediated by the interaction of LOC283299 and breast cancer cells. Therefore, LOC283299 may represent a potential predictive biomarker for early lymph node metastasis in breast cancer.

Abstract
UNLABELLED Falls are a major concern in terms of fracture risk. Although awareness rising for the absence of falls in the FRAX algorithm, our study only identified the independent predictive role of previous recurrent falls and their better conjunction use with FRAX for major osteoporotic fracture prediction in older Chinese men. INTRODUCTION Although the association of falls with fracture has been widely explored, the impact of previous falls is not included in the FRAX algorithm currently. Our aim was to examine the FRAX-independent associations between falls in the previous year and subsequent fracture risk, as well as the conjunctive use of falls and the FRAX score for major osteoporotic fracture (MOF) prediction in older Chinese people. METHODS Four thousand community older men and women aged 65 years or older were followed up for 9.9 ± 2.7 and 8.8 ± 1.5 years, respectively. The associations between falls in the previous 1 year and MOF risk by follow-up years were evaluated using the Fine and Gray model. New prediction scores were calculated by incorporating the falls and FRAX scores using the Fine and Gray model, or developed by adjusting the FRAX scores by 30% increased risk for each fall in the previous year. The predictive powers for MOF risk between the new scores and FRAX scores were evaluated by the area under the curve (AUC) and category-based net reclassification improvement index (NRI). RESULTS During the follow-up period, 139 (7.0%) men and 236 (11.8%) women had at least one incident MOF. One previous fall significantly predicted the first year incident MOF in men [hazard ratio (HR) (95%CI), 3.47 (1.02, 11.80)]. Previous recurrent falls significantly predicted a 10-year incident MOF in men [HR (95%CI), 2.42 (1.30, 4.51)]. In men, the fall-adjusting FRAX scores showed significant improvement on total net reclassification of fracture (3-6%). No improved predictive accuracy shown in women. CONCLUSION Falls in the previous year are likely to provide some predictive power to FRAX for MOF risk assessment in older Chinese men, but not women.

Abstract
Chronic inflammation is prevalent in dialysis patients. We investigated the relationship between inflammation and newly identified adipokines: leptin and adiponectin in this population. A total of 129 chronic hemodialysis patients were collected. Serum high sensitivity C-reactive protein (CRP), interleukin-6 (IL-6), leptin and adiponectin levels were determined as well as other metabolic variables. Correlation studies and multiple regression analysis were performed among variables. Our results showed that hemodialysis patients had elevated levels of inflammatory markers, leptin and adiponectin. Diabetic subjects had higher serum CRP and lower albumin levels than non-diabetics. Serum CRP levels were positively correlated with IL-6 levels and negatively correlated with albumin levels. Serum leptin levels were directly related to CRP levels while adiponectin levels were inversely related to CRP levels. A significant negative correlation was observed between serum leptin and adiponectin levels. Serum IL-6 levels were the single independent factor affecting CRP levels. Body mass index can predict both serum leptin and adiponectin levels. We conclude that hemodialysis patients are at an increased risk of chronic inflammation and diabetes patients are even more susceptible to this status. Both serum leptin and adiponectin levels are associated with inflammatory markers. As adipose tissue is the major secreting site of these adipokines, our results suggest that adipose tissue plays an important role in the pathogenesis of chronic inflammation in dialysis patients.

Abstract
Little regeneration of transected axons occurs after the damage caused by traumatic spinal cord injury (SCI), and unidirectional and irreversible fibrotic scars are thought to be the main chemical and physical obstacle for axonal regrowth in SCI pathology. We previously demonstrated that microRNA (miR)-21-5p and transforming growth factor (TGF)-β1, a central pathological mediator of fibrotic diseases, were significantly up-regulated in the lesion epicenter after SCI. Here, we found that TGF-β1 enhanced miR-21-5p expression in primary spinal fibroblasts, and regulated the expression of fibrosis-related genes. The overexpression of miR-21-5p promoted the pro-fibrogenic activity of TGF-β1 in spinal fibroblasts, while miR-21-5p knockdown attenuated this activity. We identified Smad7 as a target gene of miR-21-5p, suggesting a potential mechanism for the role of miR-21-5p in spinal fibrosis through regulating Smad7 expression. Furthermore, miR-21-5p knockdown in a mouse model significantly improved motor functional recovery after spinal cord injury. These data demonstrate that miR-21-5p functions in an amplifying circuit to enhance TGF-β signaling events in the activation of spinal fibroblasts and suggest that miR-21-5p is a potential therapeutic target in the treatment of fibrotic scar formation after SCI.

Abstract
The temperature dependence of atomic structural evolution in liquid Ag50Ga50 alloy has been studied using an in situ high energy x-ray diffraction (XRD) experiment combined with first-principles molecular dynamics (FPMD) simulations. The experimental data show a reversible structural crossover at the temperature of about 1050 K. Changes in both electrical resistivity and absolute thermoelectric power at about 1100 K strongly support the XRD results. Additionally, FPMD simulations reveal the abnormal temperature dependent behavior of partial coordination number and atomic diffusivity at about 1200 K, elucidating that the partition experimentally observed changes in structure and properties could be linked with the repartition between Ag and Ga atoms in the liquid at around 1050-1200 K. This finding will trigger more studies on the structural evolution of noble-polyvalent metals in particular and metallic liquids in general.

Abstract
CaFe_{2}O_{4} is an anisotropic S=5/2 antiferromagnet with two competing A (↑↑↓↓) and B (↑↓↑↓) magnetic order parameters separated by static antiphase boundaries at low temperatures. Neutron diffraction and bulk susceptibility measurements, show that the spins near these boundaries are weakly correlated and a carry an uncompensated ferromagnetic moment that can be tuned with a magnetic field. Spectroscopic measurements find these spins are bound with excitation energies less than the bulk magnetic spin waves and resemble the spectra from isolated spin clusters. Localized bound orphaned spins separate the two competing magnetic order parameters in CaFe_{2}O_{4}.

Abstract
The TAM receptor tyrosine kinases (TAM RTK) are a subfamily of receptor tyrosine kinases, the role of which in autoimmune diseases such as systemic lupus erythematosus has been well explored, while their functions in rheumatoid arthritis (RA) remain largely unknown. In this study, we investigated the role of soluble TAM receptor tyrosine kinases (sAxl/sMer/sTyro3) in patients with RA. A total of 306 RA patients, 100 osteoarthritis (OA) patients and 120 healthy controls (HCs) were enrolled into this study. The serum concentrations of sAxl/sMer/sTyro3 were measured by enzyme-linked immunosorbent assay (ELISA), then the associations between sAxl/sMer/sTyro3 levels and clinical features of RA patients were analysed. We also investigated whether sTyro3 could promote osteoclast differentiation in vitro in RA patients. The results showed that compared with healthy controls (HCs), sTyro3 levels in the serum of RA patients were elevated remarkably and sMer levels were decreased significantly, whereas there was no difference between HCs and RA patients on sAxl levels. The sTyro3 levels were correlated weakly but positively with white blood cells (WBC), immunoglobulin (Ig)M, rheumatoid factor (RF), swollen joint counts, tender joint counts, total sharp scores and joint erosion scores. Conversely, there were no significant correlations between sMer levels and the above indices. Moreover, RA patients with high disease activity also showed higher sTyro3 levels. In-vitro osteoclast differentiation assay showed further that tartrate-resistant acid phosphatase (TRAP)+ osteoclasts were increased significantly in the presence of sTyro3. Collectively, our study indicated that serum sTyro3 levels were elevated in RA patients and correlated positively with disease activity and bone destruction, which may serve as an important participant in RA pathogenesis.

Abstract
Graphene oxide (GO) membranes continue to attract intense interest due to their unique molecular sieving properties combined with fast permeation. However, their use is limited to aqueous solutions because GO membranes appear impermeable to organic solvents, a phenomenon not yet fully understood. Here, we report efficient and fast filtration of organic solutions through GO laminates containing smooth two-dimensional (2D) capillaries made from large (10-20 μm) flakes. Without modification of sieving characteristics, these membranes can be made exceptionally thin, down to ∼10 nm, which translates into fast water and organic solvent permeation. We attribute organic solvent permeation and sieving properties to randomly distributed pinholes interconnected by short graphene channels with a width of 1 nm. With increasing membrane thickness, organic solvent permeation rates decay exponentially but water continues to permeate quickly, in agreement with previous reports. The potential of ultrathin GO laminates for organic solvent nanofiltration is demonstrated by showing >99.9% rejection of small molecular weight organic dyes dissolved in methanol. Our work significantly expands possibilities for the use of GO membranes in purification and filtration technologies.

Abstract
Objective: To improve the understanding, diagnosis and treatment of inflammatory myofibroblastic tumor (IMT) of the hepatobiliary pancreatic system through the cases review. Methods: The clinical data of three cases of pathologically-proved IMT of the hepatobiliary pancreatic system was reported and relevant literatures were reviewed. Results: Among three cases of IMT discussed, there consisted of a case of liver, a case of gallbladder and a case of pancreas. The clinical manifestations were nonspecific, and the preoperative diagnosis was difficult. All the patients with suspected malignant tumors underwent surgical treatment. The prognosis was good, with no recurrence. Conclusion: IMT is a benign tumor and is rare in hepatobiliary pancreatic system. The clinical manifestations are not typical and the imaging examinations are not specific. Its diagnosis depends on pathology. Surgery is an effective treatment. IMT has a tendency of recurrence, and its postoperative follow-up is of great significance.

Abstract
Although the literature has reported enhanced indirect sulfation of limestone by adding Na2CO3, the amount of Na2CO3 additive required to achieve high CaO conversion is typically high (∼4.0 mol %), which commonly results in adverse effects in fluidized-bed combustion boiler systems and increased cost of sorbents. In this work, we demonstrate for the first time that trace Na2CO3 (0.1 mol %) can significantly enhance the sulfate conversion of limestone. This enhanced sulfation is attributed to the increased surface area and optimized pore size distribution. The trace Na2CO3 additive splits the pores of the original sorbents peaking at ∼70 nm into pores peaking at ∼4 nm and ∼140 nm due to the slight promotion of sintering. This well-developed pore structure results in a relatively high reactivity for sulfation. Thus, the Na2CO3 additive influences the sorbent reactivity in two ways: (1) at less than 0.5 mol %, tuning its pore structure; (2) at more than 0.5 mol %, promoting the product layer diffusion. We also find that trace amount of other metal salts, such as CaCl2 and NaCl, clearly enhance the sulfation of limestone. The strategy of enhancing limestone sulfation by the addition of trace amount of metal salts offers evident engineering and economic advantage.

Abstract
BACKGROUND Few studies have addressed prognostic markers and none has correlated molecular status and prognosis in vulvar melanomas. OBJECTIVES To evaluate the clinicopathological features of 95 cases of vulvar melanoma. METHODS p53, CD117, Ki-67, neurofibromin, brafv600e and nrasq61r immunostains, and molecular analyses by either targeted next-generation or direct sequencing, were performed on available archival materials. RESULTS Molecular testing detected mutations in KIT (44%), BRAF (25%), NF1 (22%), TP53 (17%), NRAS (9%) and TERT promoter (9%). Co-mutation of KIT and NF1 and of KIT and NRAS were identified in two and one cases, respectively. KIT mutations were significantly associated with better progression-free survival in univariate analyses. In multivariate analyses CD117 expression was significantly associated with better progression-free survival. Tumour thickness was significantly associated with worse progression-free and overall survival, and perineural invasion significantly correlated with reduced melanoma-specific survival and reduced overall survival. Cases were from multiple centres and only a subset of samples was available for molecular testing. CONCLUSIONS KIT mutations and CD117 overexpression are markers of better progression-free survival. In addition to its prognostic value, molecular testing may identify cases that might respond to targeted agents or immunotherapeutic approaches.

Abstract
PURPOSE The main purpose of the present study was to determine the anticancer properties of imperatorin - a naturally occurring coumarin compound - against SGC-7901 human gastric adenocarcinoma cells and the mouse fibroblast cell line 3T3 (normal cell line). METHODS Imperatorin effects on apoptosis induction, cell cycle phase distribution and PI3K/Akt/m-TOR signalling pathways were studied. MTT cell viability assay examined the compound's cytotoxic potential, while inverted phase contrast microscopy and fluorescence microscopy techniques were used to study morphological changes induced in SGC-7901 cells by imperatorin. Flow cytometry examined its effects on cell cycle progression while Western blot assay was used to study changes in protein expressions of PI3K/Akt/m-TOR pathway. RESULTS Imperatorin induced a dose-dependent growth inhibition of the SGC-7901 gastric cancer cells with an IC50 value 62.6 μM, while in case of normal 3T3 mouse fibroblast cells, the drug did not show significant toxicity (IC50 value 195.8 μM), indicating that the drug selectively induced cytotoxicity in gastric cancer cells. The cells became rounded up, shrunken in size and got detached from the monolayer attached to well surface. Cells treated with 10, 75 and 175 μM imperatorin indicated that they began to emit yellow or red fluorescence which is an indication of early or late apoptosis respectively. Imperatorin also induced significant DNA fragmentation along with increasing the fraction of sub-G1 cells, indicating a sub-G1 cell cycle arrest. CONCLUSION Imperatorin could prove an important lead molecule for the treatment of gastric cancer and deserves further research in vivo against more cell lines.

Abstract
Datura metel L. is a medicinal herb that contains withasteroids and has a wide range of biological activities. We isolated seven withasteroids from the flowers of D. metel L and examined their ability to inhibit immune responses in vitro and in vivo. Among the withasteroids, withasteroid B2 exhibited the strongest inhibitory effect on immune responses comparing B2 with other isolated compounds from D. metel L., including suppressing the differentiation of CD4+ T cells by inhibiting the expression and production of T cell lineage-specific master regulators and cytokines and directly suppressing the cytokine-induced Janus kinase/signal transducer and activator of transcription (JAK/STAT) signalling pathways. In the interleukin (IL)-23-induced mouse ear model of skin disease, B2 repressed disease development by inhibiting the expression of proinflammatory mediators in murine ear skin. Moreover, B2 affected the maturation of dendritic cells (DCs) in vitro which, in turn, induced T cell differentiation with an increased regulatory T cell (Treg ) phenotype and decreased T helper type 17 (Th17) phenotype. This study provides new evidence that B2 might ameliorate chronic inflammatory skin diseases by suppressing pathogenic CD4+ T cell differentiation and the IL-17+ retinoic-acid-receptor-related orphan receptor gamma t (RORγt)+ /IL-10+ forkhead box protein 3 (FoxP3)+ ratio. These findings suggest that B2 might mediate the therapeutic effects observed in psoriasis patients following treatment with D. metel L.

Abstract
Lung cancer kills more people in the US than any other malignancy. High mortalities are in part due to the diagnosis at an advanced inoperable stage where the 5-year survival is only 4%. Therefore improving survival will require increased knowledge of genes that drive the complex mechanisms of lung cancer initiation and progression. Emerging data implicate novel roles for protein arginine methylation in lung cancers. In protein arginine methylation, nitrogen/s of arginine can be post-translationally modified via the addition of a methyl group, catalyzed by a class of enzymes, protein arginine methyl transferases (PRMTs). Protein arginine methyl transferase 6 (PRMT6) is a methyl transferase that modifies histone tails, and its expression is upregulated in lung cancers, correlating with a worse overall patient survival. However, the in vivo role of PRMT6 has never been examined. In this study, we show that targeted over-expression of PRMT6 in the mouse lungs (PRMT6 gain-of-function mouse model) results in an increased chemical carcinogen-induced lung tumorigenesis. We also performed proteomics on PRMT6-associated proteins from the mouse lung and identified Interleukin-enhancer binding protein 2 (ILF2) a.k.a. nuclear factor 45 (NF45) as a novel PRMT6 interacting protein. By using a battery of cell-based assays, we show that PRMT6 plays an essential role in the regulation of the pro-proliferative functions of ILF2. Therefore, targeting PRMT6/ILF2 axis might open new possibilities for the therapeutic intervention of lung cancer.

Abstract
Objective: To explore the status of glucocorticoid application in patients with systemic lupus erythematosus (SLE) in China. Methods: Epidemiological survey was used. The SLE patients who met the 1997 classification criteria of American College of Rheumatology were enrolled. The usage of glucocorticoid and related adverse reactions were recorded and analyzed. Results: A total of 400 SLE patients were enrolled, including 35 men and 365 women. The average age was (37.4±14.0) years old, and the average duration of disease was (6.7±5.8) years. There were 310 patients using glucocorticoid as maintenance. Sixty-one percent (n=244) patients started using medium dose (prednisone 30-<60 mg/d) as the initial treatment of glucocorticoid, which lasted for(37±11)days.The time of drug duration in patients with low dose prednisone (7.5-<30 mg/d)and high dose (60-100 mg/d) was(92±20)and(17±3)days respectively (P<0.05 between 3 groups). However, patients receiving different initial dosage were of no discrepancy in the maintenance therapy. During maintenance, even though 51.0% (n=158) patients were on prednisone 2.5-5 mg/d, the duration of drug use in >5-10 mg/d groupwas longer[(29.9±3.3) months]. Patients with involvement of internal organs had a higher tendency to use 60-100 mg/d prednisone or pulse-dose therapy in the initial treatment, nevertheless these two groups had no difference of maintenance dosage. Among all 400 patients, 62 patients withdrew glucocorticoid, including 17 patients with disease remission (4.3%), 44 by self-withdrawal and one with adverse reaction. Conclusion: In China, the medium dosage of glucocorticoid is the most common initial treatment in patients with SLE.Prednisone 2.5-5 mg/d was the most common choicefor maintenance therapy. Currently, the proportion of glucocorticoid withdrawal remains low in SLE patients achieving remission.

Abstract
Abstract
Long non coding RNAs (lncRNAs) have been identified as regulators of the cell cycle, apoptosis, and DNA damage among other processes that if deregulated, may lead to cancer by acting as proto-oncogenes, tumor suppressor genes, and drivers of metastatic transformation. Using RNA sequencing we have identified 42 differentially expressed lncRNAs from a healthy cohort of parous vs. nulliparous women. After bioinformatics and RT-qPCR analysis, we have focused on a vaguely studied lncRNA called BC200 that is highly expressed in the nulliparous postmenopausal breast tissue. It is known that BC200 lncRNA is overexpressed in invasive and pre-invasive breast cancer; however, its functional role in the initiation and progression of breast cancer is poorly understood. In the present work we provide insight on the role of BC200 in the context of luminal and triple negative breast cancer (TNBC). We have confirmed that BC200 is highly expressed in breast cancer tissue and in widely used breast cancer cell lines such as MCF7, T47D, MDAMB231, and Hs578T. Using a lentiviral system we successfully obtained cell lines which stably express BC200. Overexpression of BC200 increases proliferation, migration, and invasion potential in vitro in the cell lines tested, specifically luminal T47D and TNBC MDAMB231. Xenograft studies performed in the mammary fat pad of female SCID mice confirm the role of BC200 as a tumor promoter. Tumors in mice injected with MDAMB231 cells overexpressing BC200 were 4.5 times bigger than tumors in the control group in only 6 weeks when injecting 1 million cells. Moreover, we have determined, using reverse transcriptase PCR targeting genes less than 200 kb from the start site of BC200, that when BC200 is overexpressed, CALM2 is downregulated in both T47D and MDAMB231 cell lines. CALM2 or Calmodulin is a calcium binding protein that plays a role in signaling pathways, cell cycle progression, proliferation, and apoptosis. Mutations in CALM2 are associated with increased risk of breast cancer. Our positive results on Cis regulation are being expanded using chromatin isolation by RNA immunoprecipitation to determine BC200's genome wide regulation.
These results demonstrate the participation of BC200 lncRNA in the progression of breast cancer. Notably, BC200 regulates nearby genes that have an implication in cancer progression. BC200, identified in the normal breast tissue of nulliparous women, not only plays a key role in breast cancer progression but also provides a new insight in the preventive role of pregnancy by the downregulation of the expression of this lncRNA in the normal parous breast.

Abstract
PURPOSE Visceral adipose tissue-derived serine protease inhibitor (vaspin) is an adipocytokine with insulin-sensitizing effects. Accumulating data implied that vaspin represents a compensatory mechanism but it is unknown how vaspin change during ageing. This study was designed to examine the correlation between plasma vaspin and age in a group of normal Chinese people. METHODS A total of 191 Chinese volunteers aged 19-80 years were enrolled into four groups based upon age quartiles (19-35, 36-50, 51-65 and 66-80 years). Demographic, anthropometric, metabolic covariates, vaspin and adiponectin were measured. The influence of age on plasma vaspin was analysed using SPSS 13.0. RESULTS Vaspin increased with ageing, with mean vaspin levels (ng/mL) of 1.01 ± 2.25, 1.67 ± 2.95, 2.05 ± 3.46 and 2.40 ± 3.06 for those between quartile ages 19-35, 36-50, 51-65 and 66-80 years. When divided into subgroups, vaspin increased with increasing age for both sexes, both insulin resistance and non-insulin resistance subjects and both obese and lean subjects. In univariate analyses, vaspin plasma level positively associated with age (r = 0.215, p = 0.003), adiponectin, insulin, homoeostasis model of assessment for insulin resistance index and waist-hip ratio in the whole population. The correlation between ageing and increasing vaspin remained significant after multivariate adjustments for factors such as sex, body mass index, waist-hip ratio, indices of glucose metabolism, white blood cell, lipid profile and adiponectin. Stepwise multiple regression analysis showed that age contributed 7.6 % on plasma vaspin level. CONCLUSION Vaspin level increased with ageing, independent of sex, indices of glucose metabolism, lipid profile and other markers of adiposity.

Abstract
AIMS Cubitus varus is the most common late complication of a supracondylar fracture of the humerus in children. Correction can be performed using one of a number of techniques of osteotomy but each has disadvantages. We describe a new technique for correcting post-traumatic cubitus varus using a lateral closing wedge isosceles triangular osteotomy. PATIENTS AND METHODS A lateral closing wedge isosceles triangular osteotomy was performed in 25 patients (15 male and ten female with a mean age of 9.5 years (6 to 12)) between May 2010 and April 2013. All patients had cubitus varus secondary to malunion of a supracondylar fracture, with good function of the elbow and a full range of movement. The osteotomy lines were marked on the bone with an isosceles triangular template made before surgery, after which the osteotomy was performed leaving the medial cortex intact. Fixation was performed using two lateral 2 mm Kirschner (K)-wires and patients were immobilised in an above-elbow plaster. By six to eight weeks callus was present and the wires and cast were removed. Patients were reviewed at four and six weeks, three, six and 12 months and then every two years until skeletal maturity. Clinical and radiographic outcomes were categorised as excellent, good or poor. RESULTS A total of 23 patients had an excellent and two had a good outcome at a mean final follow-up of 3.4 years (two to four). The mean post-operative carrying angle in the corrected elbow was 11.7° (7° to 18°). One patient fell, displacing the osteotomy, and needed revision of the fixation. No patient had a nerve injury. CONCLUSION A lateral isosceles triangular osteotomy and with K-wire fixation is a practical, effective, reliable, safe and simple method of correcting post-traumatic cubitus varus in children. It has inherent stability and excellent cosmesis without prominence of the lateral condyle. Cite this article: Bone Joint J 2016;98-B:1521-5.

Abstract
UNLABELLED The thresholds of trabecular bone score (TBS) require validation for clinical application in older Chinese people. The lower threshold of TBS significantly improved the accuracy of prediction by bone mineral density-based osteoporosis status for major osteoporotic fracture in older Chinese men. INTRODUCTION Trabecular bone score (TBS) is a relatively new indicator of skeletal fragility. Its clinical application warrants further investigations. Our aim was to validate and recommend practical thresholds of TBS for fracture prediction in older Chinese people. METHODS Older men and women in Mr. and Ms. Os (Hong Kong) study were followed up for an average of 9.94 ± 2.77 and 8.82 ± 1.49 years, respectively. Major osteoporotic fracture (MOF) risks of TBS category in each BMD category (normal, osteopenia, or osteoporosis) were compared using Poisson regression model. The improved fracture risk prediction power was evaluated by the sensitivity, the specificity, the area under the receiver-operating characteristic curve (AUC), and the net reclassification improvement index (NRI). RESULTS MOF incidence gradually increased with the increased risk categories of bone mineral density (BMD) and tertiles of TBS both in men and women. Compared with the lowest risk category, the rate ratios (RR, 95 % CI) of MOF for osteoporosis with the lowest TBS was 9.66 (4.19-22.26) and 6.24 (1.53-25.42) in men and women, respectively. The fracture risk for osteopenic men with the lowest TBS was significantly higher than that for normal men, with RR (95 % CI) of 4.68 (2.11-10.41). The predictive power of osteoporosis alone was significantly improved by TBS in men [mean AUC (95 % CI) rose from 0.604 (0.562-0.646) to 0.666 (0.623-0.710) and sensitivity rose from 32.5 to 64.3 %]. The improvement in predictive power was not significant in older women. CONCLUSIONS TBS in combination with BMD can predict MOF more reliably in older men than by BMD alone.
