Abstract
PURPOSE We investigated correlations of somatic BRAF V600E mutation and RET/PTC1 rearrangement with recurrent disease in Chinese patients with papillary thyroid carcinoma (ptc). METHODS This prospective study included 214 patients with ptc histologically confirmed between November 2009 and May 2011 at a single institute. RESULTS We found somatic BRAF V600E mutation in 68.7% and RET/PTC1 rearrangement in 25.7% of the patients. Although BRAF mutation was not significantly associated with clinicopathologic features such as patient sex or age, multicentric disease, thyroid capsule invasion, tumour stage, or nodal metastasis, it was significantly associated with recurrent disease. Multivariate analysis revealed that BRAF mutation and tumour size were independent risk factors associated with recurrent disease, with odds ratios of 9.072 and 2.387 respectively. The area under the receiver operating characteristic curve increased 8.3% when BRAF mutation was added to the traditional prognostic factors, but that effect was statistically nonsignificant (0.663 vs. 0.746, p = 0.124). RET/PTC1 rearrangement and nodal metastasis were significantly associated in all patients (p = 0.042), marginally associated in ptc patients (p = 0.051), but not associated in microptc patients (p = 0.700). RET/PTC1 rearrangement was not significantly associated with recurrent disease. CONCLUSIONS BRAF positivity is an independent predictor of recurrent disease in ptc.

Abstract
The CapsMorph(®) technology prepares amorphous drugs for oral delivery by encapsulating them into porous materials. Hesperidin as model compound was loaded onto AEROPERL(®) 300 Pharma using the wetness impregnation method. Hesperidin was dissolved in dimethyl sulfoxide (DMSO) and alternatively in DMSO with addition of Tween 80. The drug solutions were added dropwise to the porous material and subsequently DMSO was evaporated. The AEROPERL(®) 300 Pharma could be loaded with about 30% hesperidin in the amorphous form. Amorphous state was verified by X-ray diffraction and differential scanning calorimetry. The CapsMorph(®) formulation was compared regarding properties determining oral bioavailability, i.e., kinetic saturation solubility and dissolution rate to raw drug powder and hesperidin nanocrystals. The saturation solubility of CapsMorph(®) without Tween 80 was 654 μg/ml, which is 36-fold higher than the raw drug powder (18 μg/ml) and about 20 times higher than nanocrystals (30 μg/ml). In vitro release was faster (100% in 10 min at pH 6.8) compared to dissolution of nanocrystals with about 15%. Addition of Tween 80 to CapsMorph(®) lowered the solubility (168 μg/ml) and slowed down the release, but provided longer times of supersaturation without precipitation of drug. Based on these data, it appears that drug loaded porous materials provide better formulations compared to nanocrystals for poorly soluble drugs.

Abstract
Chrysanthemum (Chrysanthemum morifolium Ramat.) is a commercially important ornamental grown worldwide, and is also extensively used as an edible and medicinal plant. In the present work, viruses and viroids infecting chrysanthemum were investigated in China in 2012 and 2013. Typical viral symptoms were observed in field-grown chrysanthemum with leaf yellowing and mottled leaves in Wenjiang District, Sichuan Province, China. The incidence of these symptoms in the field was 12.3%. Chrysanthemum virus B (CVB), Tomato aspermy virus (TAV), Cucumber mosaic virus (CMV), Tobacoo mosaic virus (TMV), Chrysanthemum stunt viroid (CSVd), and Chrysanthemum chlorotic mottle viroid (CChMVd), which had previously been reported to infect chrysanthemum in China (2,3), were not detected by RT-PCR assay. Since these symptomatic chrysanthemum plants grew next to a tobacco field, viruses affecting tobacco were suspected as possible cause. Sixteen symptomatic leaves and 12 non-symptomatic leaves were collected and tested for Potato virus Y (PVY) presence using commercial PVY-specific DAS-ELISA kits (Catalog no. PSA20001, Agdia) Six samples were found positive for PVY. RT-PCR tests using specific primers for CP gene (CP-F 5'-ACTGTGATGAATGGGCTTATG-3'; CP-R 5'-GGCATATATGGTTCCTTTTTG-3') (4) amplified a single, expected 218-bp DNA fragment from chrysanthemum extracts from all six samples positive for PVY in ELISA. These six PCR fragments were sequenced and found 100% identical to each other. The sequence (GenBank Accession No. KJ174515) shared 99% identity with corresponding sequences of several PVY isolates (NC_001616, EF026076, HM590407, and JQ924288). The same six positive samples were subjected to a multiplex RT-PCR assay (1) to identify the PVY strain type, and all six PVY samples from Sichuan were found to belong to the PVYN-Wi strain. To our knowledge, this is the first report of the PVYN-Wi strain infecting chrysanthemum in Sichuan, China. References: (1) M. Chikh Ali et al. Plant Dis. 10:1370, 2013. (2) E. A. Nassar et al. Int.

Abstract
Considerable evidence suggests that depression is related to interhemispheric functional coordination deficits. For depression, electroconvulsive therapy (ECT) is the most rapid and effective therapy, but its underlying mechanism remains unknown. The aim of this study was to explore the impact of ECT on the interhemispheric functional coordination in depression patients. We used resting-state functional magnetic resonance imaging to observe the change of interhemispheric functional coordination with the method of voxel-mirrored homotopic connectivity (VMHC) in 11 depressed patients before and after ECT, compared with 15 healthy controls. The results showed that, compared with depression patients before ECT, VMHC was significantly increased in superior frontal gyri (BA 8), middle frontal gyri (two clusters: BA 8/9 and BA 10) and angular gyri (BA 39) in depression patients after ECT. Compared with healthy controls, VMHC in those areas was significantly lower in the middle frontal gyri (BA 8/9) and angular gyri (BA 39) in depression patients before ECT, but no significant difference was observed in the superior frontal gyri (BA 8) and middle frontal gyri (BA 10). There was no significant correlation between the changes of Hamilton Depression Rating Scale scores and changed VMHC values in those four areas in depression patients. The results suggest that ECT selectively modulated interhemispheric functional coordination in depression patients. Such may play an important mechanistic role in the treatment of depression, and may afford a useful avenue for optimizing treatment.

Abstract
Findings on the effects of weather on health, especially the effects of ambient
temperature on overall morbidity, remain inconsistent. We conducted a time series
study to examine the acute effects of meteorological factors (mainly air temperature)
on daily hospital outpatient admissions for cardiovascular disease (CVD) in Zunyi
City, China, from January 1, 2007 to November 30, 2009. We used the generalized
additive model with penalized splines to analyze hospital outpatient admissions,
climatic parameters, and covariate data. Results show that, in Zunyi, air temperature
was associated with hospital outpatient admission for CVD. When air temperature was
less than 10°C, hospital outpatient admissions for CVD increased 1.07-fold with each
increase of 1°C, and when air temperature was more than 10°C, an increase in air
temperature by 1°C was associated with a 0.99-fold decrease in hospital outpatient
admissions for CVD over the previous year. Our analyses provided statistically
significant evidence that in China meteorological factors have adverse effects on the
health of the general population. Further research with consistent methodology is
needed to clarify the magnitude of these effects and to show which populations and
individuals are vulnerable.

Abstract
Complete segmentation of diseased lung lobes by automatically identifying fissure surfaces is a nontrivial task, due to incomplete, disrupted, and deformed fissures. In this paper, we present a novel algorithm employing a hybrid two-dimensional/three-dimensional approach for segmenting diseased lung lobes. Our approach models complete fissure surfaces from partial fissures found in individual computed tomography (CT) images. Evaluated using 24 patients' lungs with a variety of different diseases, our algorithm produced root-mean square errors of 2.21 ± 1.21, 2.51 ± 1.36, and 2.38 ± 1.27 mm for segmenting the left oblique fissure (LOF), right oblique fissure (ROF) and right horizontal fissure (RHF), respectively. The average accuracies for segmenting the LOF, ROF, and RHF are 86.59%, 84.80%, and 82.62%, using our ±3-mm percentile measure. These results indicate the feasibility of developing an automatic algorithm for complete segmentation of diseased lung lobes.

Abstract
The aim of the study was to investigate and compare the clinical manifestations between HLA-B27(+) and HLA-B27(-) ankylosing spondylitis (AS) patients in order to obtain knowledge of the impact of HLA-B27 status on AS, and to inform clinical treatment. A nationwide epidemiological investigation was performed from November 2008 to October 2010. The demographic data and clinical characteristics, and the status of HLA-B27 were collected using questionnaires and laboratory assay, respectively. A total of 2144 patients (78.5% males and 78.4% HLA-B27(+) AS patients) participated in this study. The percentages of males, patients with family history, and involvement of lumbar spine, thoracic spine and hip joints, were observed to be significantly higher in the HLA-B27(+) AS patients than in their HLA-B27(-) AS peers.

Abstract
Cancer/testis antigen (CTA)-45 family (CT45) belongs to a new family of genes in phylogenetics and is absent in normal tissues except for testis, but is aberrantly overexpressed in various cancer types. Whether CT45 and other CTAs act as proto-oncogenes has not been determined. Using breast cancer as a model, we found that CT45A1, a representative CT45 family member, alone had a weak tumorigenic effect. However, its neoplastic potency was greatly enhanced in the presence of growth factors. Overexpression of CT45A1 in breast cancer cells markedly upregulated various oncogenic and metastatic genes, constitutively activated ERK and CREB signaling pathways, promoted epithelial-mesenchymal transition, and increased cell stemness, tumorigenesis, invasion, and metastasis, whereas silencing CT45A1 significantly reduced cancer cell migration and invasion. We propose that CT45A1 functions as a novel proto-oncogene to trigger oncogenesis and metastasis. CT45A1 and other CT45 members are therefore excellent targets for anticancer drug discovery and targeted tumor therapy, and valuable genes in the study of a molecular phylogenetic tree.

Abstract
UNLABELLED The objective of this study was to evaluate the potential synergistic effect of ethanol on a combination of orthophthalaldehyde (OPA) and didecyldimethylammonium chloride (DDAC) against the spores of Bacillus subtilis var. Niger. The quantitative carrier test for sporicidal testing of high-level disinfectants according to the guideline of China (Technical Standard for Disinfection 2002) was used as method. Considerable synergistic effect was observed after a 30-min treatment at 20°C. There was an augment in mean log reduction as the concentration of DDAC was increased ranging from 0·2 to 3 g l(-1) in combination with 6 g l(-1) OPA. Ten and 20% ethanol in combination with 6 g l(-1) OPA and 2 g l(-1) DDAC caused more than a 3-log reduction while either 6 g l(-1) OPA, 2 g l(-1) DDAC and 20% ethanol alone or a combination of two of the three agents produced less than a 1-log reduction. Further, 40-min exposure time of combination of OPA, DDAC and 20% ethanol led to greater than a 5-log reduction in spores, and no spore growth was observed following 60- and 90-min exposures. SIGNIFICANCE AND IMPACT OF THE STUDY Orthophthalaldehyde (OPA) is very effective at concentrations far lower than its recommended in-use concentration of 0·5% (w/v) and is equally effective against both the gram-negative and gram-positive bacteria. However, it shows lower activity against spores. The synergistic sporicidal effect exhibited by ethanol on a combination of OPA and DDAC can be considered to enhance sporicidal activity for using in situations of sterilization, to reduce in-use concentration of OPA used alone, which may minimize its side effect. OPA may be a more satisfactory and the first-choice agent to replace glutaraldehyde (GTA) as a high-level disinfectant for medical devices.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is a common and highly heritable arthropathy, but the pathogenesis of which is poorly understood, especially the mechanisms in genomics. AIM Our work is aim to study the mechanisms of AS in genomics. MATERIALS AND METHODS we used microarray dataset GSE11886 from Gene Expression Omnibus (GEO). According to our GSEA approach on the microarray datasets related to AS, we have identified the significantly associated pathways with this disease respectively dependent and independent to the factor of interferon-gamma (IFN-γ). RESULTS As a result, we have identified 9 most significant pathways in the comparison of AS patients to control under none treatment, including 5 up-regulated and 4 down-regulated pathways in IFN-gamma-independent study. On the contrary, 11 most significantly up-regulated pathways such as renin-angiotensin system, O-Glycan biosynthesis and gap junction in the comparison of AS patients to control under the treatment of IFN in IFN-gamma-dependent study. CONCLUSIONS These may be helpful for understanding the mechanisms of AS regulation under interferon-gamma treatment in genome wide.

Abstract
BACKGROUND The treatment of fractures of the distal third of the tibia and fibula usually involves two incisions, thus raising the risk of wound dehiscence, wound necrosis, infection, and the delayed union or non-union of distal tibial fractures. To decrease and prevent aforementioned serious complications, one-incision double-plating technique was advocated here. AIM The aim of this work was to evaluate the results and effects of the one-incision, double-plating technique in the fractures of distal third of the tibia-fibula and fibula. PATIENTS AND METHODS Twenty-five patients with fractures of the distal third of the tibia-fibula, were treated with one incision, double plating between June 2007 and January 2009. The reduction and fixation of the tibia and fibula were conducted in all patients using one incision. The type of fractures based on AO classification were A1 (n = 6), A2 (n = 4), B1 (n = 12) and C1 (n = 3). All patients were followed-up at least until the patient was fully weight-bearing and the soft tissues had healed (median, 15 months; range, 12-24). RESULTS Postoperative follow-up showed that 24 fractures healed within the range of the normal healing time. Only one patient with delayed union healed without surgical intervention by 7 months postoperatively. There were no cases of malunion or non-union. Importantly, at their last follow-up visit, the fracture was in excellent position and healed radiographically, and the patient could walk without pain and support. CONCLUSIONS One-incision double-plating is a safe and effective alternative for treatment of distal tibia and fibula fractures.

Abstract
Growth factor receptor-bound protein 10 (Grb10) is a Src homology 2 domain-containing protein and one of the binding partners for several transmembrane tyrosine kinase receptors, including insulin receptor (IR) and insulin-like growth factor-1 receptor (IGF1-R). The hippocampus, which is critical for cognitive functions, is one of the main distribution areas of Grb10 in the central nervous system. In recent years, diabetic encephalopathy has been defined as a third type of diabetes and the IGF1-IR pathway was shown to be critical for the neuropathogenic process of cognitive disorder in diabetes. However, the role of endogenous Grb10 in regulating the IGF1-IR pathway and neurobehavioural changes is not explicit. The present study aimed to determine the in vivo function of endogenous Grb10 in diabetic encephalopathy and the underlying mechanisms. Using stereotaxic surgical techniques and lentiviral vectors expressing specific short hairpin RNA, we could steadily knockdown Grb10 expression in the hippocampus. More importantly, we demonstrated that hippocampus-specific modulation of Grb10 protein levels led to a prominent remission of cognitive disorder, including improvements in both ultrastructural pathology and abnormal neurobehavioural changes. Our findings indicate that endogenous overexpression of Grb10 functions as a suppressor of the IGF1-IR pathway, which may represent an important mechanism for regulating cognitive disorder in diabetes.
