Abstract
BACKGROUND/OBJECTIVES To investigate the relationship between the cross-sectional visceral adipose tissue (VAT) areas at different anatomic sites and the total VAT volume in a healthy Chinese population using quantitative computed tomography (QCT), and to identify the optimal anatomic site for a single slice to estimate the total VAT volume. SUBJECTS/METHODS A total of 389 healthy Chinese subjects aged 19-63 years underwent lumbar spine QCT scans. The cross-sectional area of total adipose tissue and VAT were measured using the tissue composition module of the software (QCT Pro, Mindways) at each intervertebral disc level from T12/L1 to L5/S1, as well as at the umbilical level. The total VAT volume was defined as the fat areas multiplied by the height of vertebral body for all six slices. Statistical analysis was performed to determine the correlation between single-slice VAT areas and the total VAT volume. Moreover, the optimal anatomic site for a single slice to estimate the total VAT volume was identified by multiple regression analysis. RESULTS The cross-sectional area of VAT and subcutaneous adipose tissue (SAT) measured at each anatomic site was all highly correlated with the total VAT volume and the total SAT volume (r = 0.89-0.98). Additionally, the VAT area measured at the L2/L3 level showed the strongest correlation with the total VAT volume (r = 0.98, P < 0.001). Covariates including age, gender, BMI, waist, and hypertension make a slight effect on the prediction of the total VAT volume. CONCLUSION It is feasible to perform measurements of VAT area on a single slice at L2/L3 level for estimating the total VAT volume.

Abstract
Sr4Ru3O10, the n = 3 member of the Ruddlesden-Popper type ruthenate Srn+1RunO3n+1, is known to exhibit a peculiar metamagnetic transition in an in-plane magnetic field. However, the nature of both the temperature- and field-dependent phase transitions remains as a topic of debate. Here, we have investigated the magnetic transitions of Sr4Ru3O10 via single-crystal neutron diffraction measurements. At zero field, we find that the system undergoes a ferromagnetic transition with both in-plane and out-of-plane magnetic components at Tc ≈ 100 K. Below T * = 50 K, the magnetic moments incline continuously toward the out-of-plane direction. At T = 1.5 K, where the spins are nearly aligned along the c axis, a spin reorientation occurs above a critical field Bc, giving rise to a spin component perpendicular to the plane defined by the field direction and the c axis. We suggest that both the temperature- and field-driven spin reorientations are associated with a change in the magnetocrystalline anisotropy, which is strongly coupled to the lattice degrees of freedom. This study elucidates the long-standing puzzles on the zero-field magnetic orders of Sr4Ru3O10 and provides new insights into the nature of the field-induced metamagnetic transition.

Abstract
OBJECTIVES Methods to evaluate the relative contributions of demyelination vs axonal degeneration over the long-term course of MS are urgently needed. We used magnetic resonance diffusion tensor imaging (DTI) to estimate degrees of demyelination and axonal degeneration in the corpus callosum (CC) in cases of MS with different final outcomes. MATERIALS AND METHODS We determined DTI measures mean diffusivity (MD), fractional anisotropy (FA), and axial (AD) and radial (RD) diffusivities in the CC of 31 MS patients, of whom 13 presented a secondary progressive course, 11 a non-progressive course, and seven a monophasic course. The study participants were survivors from an incidence cohort of 254 attack-onset MS patients with 50 years of longitudinal follow-up. As reference, we included five healthy individuals without significant morbidity. RESULTS In patients with secondary progression, compared to all other groups, the corpus callosum showed increased RD and reduced FA, but no change in AD. None of the parameters exhibited differences among non-progressive and monophasic course groups and controls. CONCLUSION Increased RD was observed in secondary progressive MS, indicating significant myelin loss. Normal RD values observed in the clinically isolated syndrome and non-progressive groups confirm their benign nature. AD was not a characterizing parameter for long-term outcome. Demyelination revealed by increased RD is a distinguishing trait for secondary progression.

Abstract
Fibroblast growth factor (FGF) signaling has been implicated in the regulation of osteogenesis in both intramembranous and endochondral ossifications. In the developing palate, the anterior bony palate forms by direct differentiation of cranial neural crest (CNC)-derived mesenchymal cells, but the signals that regulate the osteogenic cell fate in the developing palate remain unclear. In the present study, we investigated the potential role of FGF signaling in osteogenic fate determination of the palatal mesenchymal cells. We showed that locally activated FGF8 signaling in the anterior palate using a Shox2Cre knock-in allele and an R26RFgf8 allele leads to a unique palatal defect: a complete loss of the palatine process of the maxilla as well as formation of ectopic cartilaginous tissues in the anterior palate. This aberrant developmental process was accompanied by a significantly elevated level of cell proliferation, which contributes to an abnormally thickened palatal tissue, where the palatine process of the maxilla would normally form, and by a complete inhibition of Osterix expression, which accounts for the lack of bone formation. The coexpression of Runx2 initially with Sox9 and subsequently with Col II in the ectopic cartilaginous tissues indicates a conversion of osteogenic fate to a chondrogenic one. Consistent with the unique palatal phenotype, RNA-Sequencing analysis revealed that the augmented FGF8 signaling downregulated genes involved in ossification, biomineral tissue development, and bone mineralization but upregulated genes involved in cell proliferation, cartilage development, and cell fate commitment, which was further supported by quantitative real-time reverse transcription polymerase chain reaction validation of selected genes. Our results demonstrate that FGF8 signaling functions as a negative regulator of osteogenic fate and is sufficient to convert a subset of CNC cell-derived mesenchymal cells into cartilage in the anterior hard palate, which will have implications in future directed differentiation of CNC-derived precursor cells for clinical application.

Abstract
The safety of progestogens as a class has drawn much attention after the publication of data from the Women’s Health Initiative (WHI) trial, particularly with respect to cardiovascular disease. Depending on the chemical structure, pharmacokinetics, receptor affinity and potency of action, progestogens have a divergent range of properties that may translate to very different clinical effects. The purpose of this review is to describe the role of varied progestogens in hormone replacement therapy (HRT), especially focusing on blood lipids, which are the most important parameters for assessing cardiovascular disease risk.

Abstract
Mutations in Plastin-3 (PLS3) have been identified as a cause of X-linked osteoporosis. To reveal the molecular mechanism of PLS3 on osteoporosis, we characterized the p.Ala253_Leu254insAsn mutation in PLS3. We first identified Lymphocyte cytosolic protein 1 (LCP1) as a binding partner of PLS3 and the mutation disrupted the interaction between them. We then confirmed the roles of PLS3 and LCP1 in the regulation of intracellular Ca2+ , which was weakened by the mutant PLS3. Moreover, the interaction between PLS3 and LCP1 was enhanced under a low concentration of extracellular Ca2+ . However, the mutation in PLS3 weakened the responsiveness. The reduced regulation on Ca2+ caused by p.Ala253_Leu254insAsn may be the possible molecular mechanism of osteoporosis.

Abstract
UNLABELLED The main aim of this retrospective cross-sectional study was to examine the relationship between vertebral compression fracture and thoracolumbar Cobb angles. Fracture prevalence was found to be significantly higher for patients with moderate [odds ratio (OR) = 4.78 (2.88-7.95)] or severe kyphosis [OR = 10.7 (5.11-22.40)] than for patients with mild kyphosis. The relationship between degree of thoracolumbar kyphosis and vertebral compression fracture was analyzed. INTRODUCTION The hypothesis that vertebral compression fracture in women is related to thoracolumbar kyphosis severity was tested, and a clinically important cutoff degree of sagittal thoracolumbar Cobb angle (TLCobb) was determined. METHODS Demographic data, clinical data, and quantitative computed tomography (QCT) findings were compiled for 212 postmenopausal women with thoracolumbar fracture (study group) and 150 postmenopausal women with degenerative lumbar disease (control group). Group proportions and characteristics were compared with chi-squared tests and unpaired t tests, respectively. RESULTS In this retrospective cross-sectional study cohort, 17 patients had T11 fractures, 79 had T12 fractures, 89 had L1 fractures, and 27 had L2 fractures. QCT findings and TLCobb differed between the study and control groups (both p < 0.001). No significant differences were found in body mass index (BMI), disk height, or coronal TLCobb. After adjustment for age, BMI, and QCT findings, fracture prevalence was found to be higher in the thoracolumbar kyphosis study group than in the control group [OR = 6.16, 95% confidence interval (CI) 3.88-9.78]. Sagittal TLCobbs of 7.5-15° and >15° were associated with an increased fracture prevalence, with ORs of 4.78 (2.88-7.95) and 10.7 (5.11-22.40), respectively. CONCLUSION Vertebral fracture prevalence in postmenopausal women was found to be associated with thoracolumbar kyphosis. A TLCobb sagittal angle >15° should be considered an indicator for vertebral fracture assessment.

Abstract
Type 2 diabetes mellitus (T2-DM) is a chronic metabolic disorder characterized by high blood glucose levels. T2-DM patients suffer from many complications, such as diabetic fatty liver and diabetic nephropathy. The liver, the pivotal organ involved in both glucose and lipid metabolism, is primarily damaged in T2-DM patients, especially in those with high levels of blood lipid. In this study, the hepatoprotective activity of ginsenoside Rg1 was investigated in a T2-DM rat model. The results revealed a potent hepatoprotective effect of ginsenoside Rg1. This effect was primarily mediated by the antiapoptotic effect, inhibition of JNK activity, and suppression of inflammation after ginsenoside Rg1 treatment. Ginsenoside Rg1 also lowered the blood glucose level and insulin resistance index in T2-DM rats. Moreover, the blood lipid profile (total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels) and liver function (aspartate transaminase and alanine transaminase levels) improved after ginsenoside Rg1 treatment. The aforementioned hepatoprotective effects of ginsenoside Rg1 in the T2-DM rat model suggests its clinical potential as an adjuvant drug for T2-DM therapy, especially for T2-DM patients with fatty liver disease.

Abstract
OBJECTIVE To summarize ultrasound features associated with medullary thyroid carcinoma (MTC) and investigate the predictive value of ultrasonography in preoperative diagnosis of MTC. METHODS The sonographic and clinical data were studied in a series of nodules histologically proven as MTC collected from January 1993 to January 2013. RESULTS A total of 86 patients (92 nodules proven as MTC) were enrolled in the study with an average age of (47±12) years.Among the MTCs, 21.7%(20/92) were excluded because of missing data and the remained 78.3%(72/92) had complete data with the average diameter of (2.1±1.3) cm.The common US findings for MTC were solid, hypoechogenicity, regular sharp, well-defined margin, AP/ TR<1 and calcification (mostly microcalcification). Calcification and vascularization were more common in MTC nodules(48.6% vs 5.6%, P=0.001). Nodules with enlargement of cervical lymph node tended to be undergone FNAB(76.0% vs 55.3%, P=0.084), and ill-defined margin was more common in MTC nodules with cervical lymph node metastasis(36.4% vs 12.8%, P=0.009). CONCLUSION Despite having a few US features closely linked to the malignant nodules such as solid, hypoechogenicity and with microcalcification, the MTC nodules also have specific US imaging characteristics as regular sharp, well-defined margin and AP/ TR<1.

Abstract
Abstract
Background: The AURKA gene encoding Aurora kinase-A (Aurora-A) protein is localized on chromosome 20q13 that is frequently amplified and overexpressed across multiple cancer types correlating with patient prognosis. Aurora-A plays a pivotal role in faithful segregation of chromosomes and normal progression of mitosis, peaking at G2/M followed by degradation at the end of mitosis by APC/C (Cdh1). However, regulation of Aurora-A protein stability in human cancer cells is not well elucidated. Here, we show that Aurora-A is targeted for ubiquitination and degradation by SCF complex involving eEF1α2 and PTEN in human breast cancer cells. Methods: Using a panel of breast cancer cell lines, as in vitro models, the eEF1α2 was knocked down or ectopically expressed to test the stability of Aurora-A protein. For in vivo models, tissue micro arrays of human breast cancer were immunostained for Aurora-A and eEF1α2 expression and categorized values were statistically tested by Chi-squared test. In addition, the public breast cancer dataset (Transbig) was used to predict breast cancer prognosis by Kaplan-Meier survival analysis. Results: In breast cancer cell lines and patient samples, an eEF1α2 non-expressing group showed a trend of higher Aurora-A expression than eEF1α2 expressing group, whose trend was significant in patient samples (P<0.05). Knocking down of eEF1α2 enhanced Aurora-A protein stability. In contrast, ectopic expression of eEF1α2 dramatically decreased Aurora-A protein stability. Inhibition of proteasome activity by MG132 could restore the Aurora-A protein in eEF1α2 expressing cells. Biochemical assays showed the direct binding between eEF1α2 and Aurora-A, and eEF1α2 dependent ubiquitination of Aurora-A. Inverse correlation of the expression levels of the two proteins was also observed throug the cell cycle, with eEF1α2 levels being high from G1 through G2 phases while Aurora-A expression peaked from G2/M phase through cytokinesis. Taken together, these findings highlight eEF1α2 as a novel negative regulator destabilizing Aurora-A through ubiquitin-proteasome proteolytic pathway. Further, mechanistic studies revealed that eEF1α2 enhanced the interaction of SCF E3 ubiquitin ligase complex protein; FBXW7 and Cul1, with Aurora-A. In line with this scenario, knocking down of Cul1 increased Aurora-A level. Since PTEN loss was reported to stabilize Aurora-A through inhibiting SCF complex, we tested the significance of PTEN loss in our model. Knocking down of PTEN further stabilized Aurora-A suggesting an independent role of PTEN from eEF1α2 in destabilizing Aurora-A. When eEF1α2 expressing cells were treated with AKT inhibitor, Aurora-A was destabilized with enhanced bindings between Aurora-A and FBXW7/Cul1. Lastly, low PTEN expression correlated with poor prognosis of Aurora-A over expressing breast cancer patients (P<0.01). Conclusions: Aurora-A overexpression in human breast cancer cells may be associated with loss of eEF1α2 and PTEN due to reduced interaction of SCF with Aurora-A. Findings indicate significant prognostic and therapeutic implications of altered expression of eEF1α2/PTEN/Aurora-A pathways among Aurora-A subset of breast cancer patients.

Abstract
BACKGROUND Although both obesity and hypertension are known risk factors for disability, the joint association of obesity and hypertension with risk of disability is unknown. This paper is aim to examine the joint association of obesity and hypertension with risk of disability. METHODS Cross-sectional study with 8060 elderly community-dwelling individuals participating in the survey initiated by Shanghai Health and Family Planning Commission from March to September 2013. Obesity was measured using the body mass index (BMI) in World Health Organization (WHO) Asia criteria. Hypertension, based on the doctor's diagnosis, was obtained through face-to-face interview. Disability was measured using the self-reported physical self-maintenance scale (PSMS) and the instrumental activities of daily living (IADL) scale developed by Lawton and Brody. RESULTS A total of 8.97% of participants reported ADL disability, and 15.18% for IADL disability. After adjusting social demographics and chronic conditions, the risk of ADL disability was progressively greater in obese persons with hypertension (OR=1.40, 95% CI=1.05-1.89), underweight persons without hypertension (OR=2.05, 95% CI=1.29-3.25), and underweight persons with hypertension (OR=2.14, 95% CI=1.36-3.36). For IADL disability, only underweight persons with hypertension were significantly associated (OR=1.65, 95% CI=1.23-2.21). CONCLUSIONS Low or extremely high BMI, independent of its metabolic consequences, is a risk factor for disability among the elderly. Simple hypertension wasn't significantly associated with disability. In addition, having hypertension significantly increased the risk of ADL disability in obese individuals and IADL disability in underweight individuals.

Abstract
Composition-graded films (CGF) of fluoroapatite (FAP) and poly(3-hydroxybutyrate- co-4-hydroxybutyrate) (PHB) were prepared via electrospinning solutions of FAP and PHB using a gradient composition of CGF. Thermal properties, mechanical properties and surface morphology of the films were investigated. Designed thermal and mechanical properties obtained by precise control of the composition gradient of the FAP/PHB CGF. The introduction of FAP in pure PHB film significantly changed the mechanical properties, such as tensile strength and extension rate of the pure PHB. Mouse fibroblast cells (L-929) were cultured on FAP/PHB uniform-films; the MTT test and cell morphology analysis indicate good biocompatibility of the modified CGF. This new method of processing makes CGF a potential candidate as an electrospinning scaffold material for tissue engineering.

Abstract
OBJECTIVE To explore development status in different types of the hand bone and its developmental characteristics with Poland syndrome. METHODS There were 32 cases with Poland's syndrome who accepted bilateral hand X-ray examination in Department of Hand Surgery, Beijing Jishuitan Hospital from February 2013 to August 2014.There were 24 male and 8 female patients aged from 1.0 to 15.0 years with median age of 2.4 years. Right hand deformity was 23 cases and left hand deformity was 9 cases. According to Tanner-Whitehouse skeletal age scoring system, 20 bones (radius and ulna, 7 carpal bones, 11 metacarpal and phalangeal bones) selected from the affected and contralateral limb respectively, were evaluated. Besides, hand deformity of the cases was classified into 5 types based on relevant literature. Each bone was given an individual age using the references of Greulich-Pyle chart. The average of all individual ages was taken as gross bone age, the average of individual ages of radius and ulna was taken as bone age of long bones, the average of individual ages of carpal bone was taken as bone age of carpal bones, and the average of individual age of metacarpal and phalangeal bones was taken as bone age of short bones.The delay of bone age was evaluated by correlation test, while the curve of cubic equation was used for analyzing the variance of skeletal development with age. RESULTS The delay of long bone age of patients with Poland's syndrome in this study were 0-1.9 years ((0.5±0.5) years), 0-2.2 years ((0.7±0.5)years) for carpal bone, 0.5-2.0 years((0.6±0.4) years)for short bone and 0.1-1.7 years((0.6±0.4)years) for gross bone.Twelve cases in type Ⅱ hand deformity, 15 cases in type Ⅲ and 5 cases in type Ⅳ. The delay of bone ages, including long bone age, carpal bone age, short bone age and gross bone age, was not related with gender and side(all P>0.05), but related with degree of deformity(F=3.663-12.971, P=0.000-0.038). CONCLUSION Compared with normal upper limb, the bone age in the affected limb in Poland's syndrome is delayed and it is correlated with gender, age and the extent of hand deformity and negative with side.

Abstract
A new HLA-G allelic variant, HLA-G*01:19, was identified in a southern Chinese Han population by polymerase chain reaction-sequence-based typing (PCR-SBT), cloning and phasing. HLA-G*01:19 differs from HLA-G*01:04:01 by a nonsynonymous cytosine at position 99 in exon 2, resulting in amino acid change from valine to leucine at codon 34 of the mature HLA-G molecule.

Abstract
A new MICA allelic variant, MICA*012:05, has been identified in a Chinese Mongolian population. Following polymerase chain reaction-sequence-based typing (PCR-SBT), this new allele was further confirmed by cloning and sequencing. MICA*012:05 was linked to an HLA-A*24-C*01-B*55:02-DRB1*09 haplotype. MICA*012:05 differs from MICA*012:01 by a single synonymous C to T substitution at nucleotide position 269 in exon 3.

Abstract
OBJECTIVE To measure the clivo-axial angle (CAA) and cervicomedullary angle (CMA) in upper cervical deformity patients who underwent computer-assisted posterior upper cervical reduction and fixation surgery, and analyze their correlation. METHODS In the study, 25 patients with symptomatic upper cervical deformity were chosen for measurement of preoperative and postoperative CMA and CAA using magnetic resonance imaging (MRI) and intraoperative C-arm. The angle between the clivus plane and the straight line parallel to that of the posterior margin of the C2 vertebral body was defined as CAA; moreover, the angle between the straight line parallel to the ventral side of the cervical spinal cord and the straight line parallel to that of the ventral side of the medulla oblongata was defined as CMA. Two experienced spinal surgeons performed the measurements. The CAA and CMA were measured three times, and the mean value was considered as the result. RESULTS Analyses of the CAA and CMA were performed with Wilcoxon rank test, which showed that there was consistency between the CAAs measured with MRI and intraoperative C-arm. The result showed that the postoperative CAA and CMA increased significantly compared with preoperation (P<0.001). Through Spearman rank correlation analysis, the preoperative CAA was positively correlative with the CMA (r=0.902, P<0.001), and so was the postoperative CAA (r=0.921, P<0.001). CONCLUSION Preoperative and postoperative CAA in upper cervical deformity patients is significantly correlative with preoperative and postoperative CMA. CAA can be measured during surgery using intraoperative CT or C-arm based three-dimension navigation, and may predict the patient's CMA, which cannot be measured during operation, but is essential for evaluating the decompression and reduction of the spinal cord.
