Abstract
Objective: To investigate the infection pattern and etiological characteristics of a case of human infection with highly pathogenic avian influenza A (H7N9) virus and provide evidence for the prevention and control of human infection with highly pathogenic avian influenza virus. Methods: Epidemiological investigation was conducted to explore the case's exposure history, infection route and disease progression. Samples collected from the patient, environments and poultry were tested by using real time reverse transcriptase-polymerase chain reaction (RT-PCR). Virus isolation, genome sequencing and phylogenetic analysis were conducted for positive samples. Results: The case had no live poultry contact history, but had a history of pulled chicken processing without taking protection measure in an unventilated kitchen before the onset. Samples collected from the patient's lower respiratory tract, the remaining frozen chicken meat and the live poultry market were all influenza A (H7N9) virus positive. The isolated viruses from these positive samples were highly homogenous. An insertion which lead to the addition of multiple basic amino acid residues (PEVPKRKRTAR/GL) was found at the HA cleavage site, suggesting that this virus might be highly pathogenic. Conclusions: Live poultry processing without protection measure is an important infection mode of "poultry to human" transmission of avian influenza viruses. Due to the limitation of protection measures in live poultry markets in Guangzhou, it is necessary to promote the standardized large scale poultry farming, the complete restriction of live poultry sales and centralized poultry slaughtering as well as ice fresh sale.

Abstract
We extent the recently developed Multi-Layer Multi-Configuration Time-Dependent Hartree method for Bosons for simulating the correlated quantum dynamics of bosonic mixtures to the fermionic sector and establish a unifying approach for the investigation of the correlated quantum dynamics of a mixture of indistinguishable particles, be it fermions or bosons. Relying on a multi-layer wave-function expansion, the resulting Multi-Layer Multi-Configuration Time-Dependent Hartree method for Mixtures (ML-MCTDHX) can be adapted to efficiently resolve system-specific intra- and inter-species correlations. The versatility and efficiency of ML-MCTDHX are demonstrated by applying it to the problem of colliding few-atom mixtures of both Bose-Fermi and Fermi-Fermi types. Thereby, we elucidate the role of correlations in the transmission and reflection properties of the collisional events. In particular, we present examples where the reflection (transmission) at the other atomic species is a correlation-dominated effect, i.e., it is suppressed in the mean-field approximation.

Abstract
Glanzmann's thrombasthenia (GT) is a rare bleeding disorder characterized by spontaneous mucocutaneous bleeding. The disorder is caused by quantitative or qualitative defects in integrin αIIbβ3 (encoded by ITGA2B and ITGB3) on the platelet and is more common in consanguineous populations. However, the prevalence rate and clinical characteristics of GT in non-consanguineous populations have been unclear. We analyzed 97 patients from 93 families with GT in the Han population in China. This analysis showed lower consanguinity (18.3%) in Han patients than other ethnic populations in GT-prone countries. Compared with other ethnic populations, there was no significant difference in the distribution of GT types. Han females suffered more severe bleeding and had a poorer prognosis. We identified a total of 43 different ITGA2B and ITGB3 variants, including 25 previously unidentified, in 45 patients. These variants included 14 missense, 4 nonsense, 4 frameshift, and 3 splicing site variants. Patients with the same genotype generally manifested the same GT type but presented with different bleeding severities. This suggests that GT clinical phenotype does not solely depend on genotype. Our study provides an initial, yet important, clinical and molecular characterization of GT heterogeneity in China.

Abstract
BACKGROUND Copy Number Variations (CNVs) are an important genetic cause of a number of neurodevelopmental disorders (NDs). However, the association between CNVs and the development and prognosis of fetal isolated mild ventriculomegaly (IMV) is unclear. OBJECTIVES To investigate possible associations between CNVs and the development of fetal IMV. METHODS This retrospective study recruited 154 subjects with ultrasound-confirmed fetal IMV and 190 subjects in a control cohort who underwent a high-risk prenatal serum screening program. The exclusion criteria included fetus G-banding chromosomal abnormality or positive fetus TORCH infection. DNA samples from all 344 fetuses were examined by an SNP-array. Developmental outcomes were assessed during postnatal follow-up. RESULTS Fourteen pathogenic CNVs (pCNVs) were identified in 13 out of 154 IMV fetuses. Three pCNVs were found in 3 out of 190 subjects in the prenatal screening high-risk cohort, with a significant difference (P value=0.016, X2 test). Notably, the 14 pCNVs detected in the IMV cohort were all associated with neurodevelopmental disorders (NDs), including autism, intellectual disability. Among the 13 IMV fetuses carrying pCNVs, five subjects were found in the postnatal follow-up to manifest NDs, including two with autism and three with mild neurodevelopmental delay. The other 8 subjects consisted of three normal infants younger than 12-months old, two lost in the follow-up, and three with the termination of pregnancy. Out of 141 IMV subjects without detectable pCNVs, 123 subjects showed normal development, 16 were lost in the follow-up, 2 subjects terminated the pregnancy due to fetal hydrocephalus or congenital heart disease in the late fetus development. CONCLUSIONS This study suggests an association between pCNVs and fetal IMV. pCNVs may be involved in the pathological process of fetal IMV and postnatal NDs. Identifying specific genomic alterations may provide an insight into pathogenetic mechanism and aid better diagnosis and prognosis of neurodevelopmental outcomes in fetal IMV.

Abstract
To investigate the characteristics of somatic mutation or copy number variations in Chinese breast cancer, tumor tissues from 105 patients diagnosed at age from 26 to 81 (median age 48) were assessed by next-generation sequencing technology using a customized panel, including 33 genes of putative tumor suppressors or oncogenes. At least one genetic alteration (including mutations, copy number variations and fusion genes) was observed in 99/105 (94%) samples. Similar to the previous report in TCGA dataset, TP53 (49%) and PIK3CA (43%) were the most frequently mutated genes, which occurred in a significant mutual exclusive manner (p<0.05). Three genes including MYC copy number amplification (35%), FGFR1 (19%) and GATA3 mutation (16%) were altered at the frequency of >10% in our dataset, in which the occurrence of MYC amplification was higher than the TCGA cohort (22%, p<0.05). Importantly, we identified four fusion genes of FGFR1 including one previously reported (TACC1-FGFR1) and three novel fusion ones (MIR1268A-FGFR1, LZTS1-AS1-FGFR1, and LINC01605-FGFR1). Unlike the high prevalence of CCND1 amplification (17%) and CDH1 mutations (13%) in TCGA dataset, genetic variations of CCND1 and CDH1 in our study occurred at a low frequency with 2% and 4%, respectively (p<0.05). In addition, we also identified three novel ESR1 mutations (ESR1 G74R, D230H and M250T) in the untreated patients with early breast cancer. Furthermore, nonnegative matrix factorization (NMF) clustering of genetic variations revealed five distinct molecular classes in our dataset. NMF class I was characterized by a high rate of HR+/ERBB2- tumors (80%) and genetic alterations of FGFR1 (100%). A gain of ERBB2 gene was observed in 93% of NMF class II along with TOP2A amplification in 57% of HR+/ERBB2+ tumors. NMF class III was characterized by a high rate of HR+/ERBB2- (95%) and GATA3 mutations (75%) without TP53 mutation. The characteristics of NMF class IV were the high rate of PIK3CA mutations (95%) and HR+/ERBB2- tumors (75%) along with low rate of TP53 mutations. More HR-/ERBB2- tumors (39%) were observed in NMF class V with a high rate of MYC amplification (82%) and TP53 mutation (89%). Further analysis in the TCGA cohort revealed the patients in NMF class V had the shorter survival time than other clusters. Collectively, we identified several novel genetic variations and generated a preliminary profile of somatic genetic aberrations that could classify Chinese breast cancer in this study, and may represent novel therapeutic targets for molecular subsets of breast cancer.

Abstract
Abstract
Reduction of selenium-binding protein 1 (SELENBP1) has been frequently observed in various solid tumors, and associated with poor clinical prognosis, implicating SELENBP1 as a potential tumor suppressor. However, the molecular mechanism underlying the transcriptional regulation of SELENBP1 remains poorly understood. In this study, we first analyzed the relationship between SELENBP1 mRNA levels and clinical or pathological features of breast cancer in METABRIC datasets, and found that SELENBP1 mRNA levels were differentially expressed in PAM50 molecular subtypes with highest levels in Luminal A/B subtype and lowest levels in Basal-like/Claudin-low subtype, indicating that SELENBP1 might function as the downstream player of estrogen receptor α (ERα). Following the adjustment of clinicopathological characteristics including the menopausal status, ER/HR/ERBB2 status, TNM stage and histological grade, the Kaplan-Meier survival analysis surprisingly showed that patients with higher levels of SELENBP1 mRNA (n=43) had shorter survival time than those with moderate levels of SELENBP1 expression (n=102) in Luminal A subtype (Hazard Ratio 1.59; 95% CI 0.99-2.54; Logrank p=0.0367), although the patients with lower SELENBP1 levels were consistent the poor prognosis in Basal-like/Claudin-low subtype (Hazard Ratio 1.54; 95% CI 0.97-2.44; Logrank p=0.0356). To elucidate this controversy, we knocked down the expression of ERα in MCF-7 cells using shRNA targeting ERα, and found that knockdown of ERα resulted in the down-regulation of mRNA and protein expression of SELENBP1. In addition, SELENBP1 promoter-driven luciferase reporter assay reveled ERα regulated the expression of SELENBP1 at transcriptional level. Interestingly, we further found that the addition of 4-hydroxytamoxifen (4-OHT) led to a dramatic reduction of SELENBP1 protein expression in MCF-7 cells, while forced expression of SELENBP1 in MCF-7 cells significantly enhanced 4-OHT-mediated inhibition of anchor-independent cancer cell growth. Collectively, these results suggested that the transcriptional induction of SELENBP1 by ERα might function as a downstream tumor suppressor in breast cancer cells, but endocrine therapy led to the down-regulation of SELENBP1 expression due to the blocking of ERα signaling in the patients with Luminal subtype, which was likely to explain the observation of differential predictive value for SELENBP1 mRNA levels in the Luminal and Basal-like/Claudin-low subtypes. Further investigation in vitro and in vivo has been ongoing in our laboratory, and the results from which will help us better understand the clinical relevance for SELENBP1 as a promising therapeutic target in improving the efficacy of endocrine therapy.

Abstract
Abstract
Emerging evidence has revealed that the mutations in estrogen receptor alpha (ERα) gene (ESR1) is frequently observed in ER+ metastatic breast cancer, and is associated with the aggressively invasive and metastatic phenotype in advanced breast cancer due to the resistance of endocrine therapy. In our previous study, we have identified three novel mutations of ESR1, including ESR1 G74R, D230H and M250T, in the untreated patients with early breast cancer. However, the functional roles for these novel mutations in the cellular biology of breast cancer remain to be elucidated. In this study, we described the molecular mechanism underlying potential roles for the novel mutation ESR1 p.Met250Thr (c.749T>C) in regulating the cellular invasiveness of breast cancer. Firstly, we found, as compared with wild-type (WT) HA-ESR1, forced expression of HA-ESR1 M250T enhanced the invasive capacity of breast cancer MCF-7 cells by using Transwell assay. Moreover, we found that the levels of miR-190 were significantly up-regulated in the MCF-7 (HA-ESR1 M250T) cells, and further verified that miR-190 played an important role in ESR1 M250T-mediated induction of cellular invasiveness by using specific shRNA to knock down miR-190 levels in MCF-7 (HA-ESR1 M250T) cells. Further bioinformatics analysis showed that there were several half Estrogen Response Elements (EREs) in the promoter region of Talin-2, as the host gene of miR-190. Talin-2-driven luciferase reporter assay indicated ESR1 M250T resulted in a higher increase in the luciferase activity than ESR1 WT. Chromatin-immunoprecipitation (ChIP) assay identified a higher binding ability with Talin-2 promoter for ESR1 M250T than ESR1 WT. Collectively, our mechanistic study revealed that the ESR1 M250T mutation, located in the DNA-binding domain, increased the invasive capacity of breast cancer cells via the transcriptional induction of Talin-2 and miR-190. The potential role for ESR1 M250T in affecting the efficacy of endocrine therapy has been under the investigation in our laboratory, and the result from which will help us better elucidate the clinical relevance for novel ESR1 mutations in affecting the sensitivity of endocrine therapy.

Abstract
PURPOSE The role of postmastectomy radiotherapy following primary systemic treatment in patients with clinical T1-2N1 breast cancer remains a controversial issue. The purpose of this study was to evaluate the benefit of postmastectomy radiotherapy following primary systemic treatment. PATIENTS AND METHODS Between 2005 and 2012, in two independent institutions, female patients with T1-2N1 breast cancer receiving primary systemic treatment followed by mastectomy and lymph node dissection because bad response, then treated with or without chest wall and regional lymph node irradiation have been studied retrospectively. The patients received normofractionated radiotherapy using 3D conformal photons or electron techniques. Locoregional recurrence-free survival, distant metastasis-free survival and disease-free survival were calculated using Kaplan-Meier method. Univariate analysis of potential prognostic factors was performed using log-rank test. RESULTS Eighty-eight patients have been studied. Of them, 75 patients received postmastectomy radiotherapy. At surgery, 53 patients achieved ypN0. Median follow-up was 67 months. Postmastectomy radiotherapy significantly improved locoregional recurrence-free survival, with a 5-year rate of 96.9% versus 78.6% in the group that did not have postmastectomy radiotherapy. In the subgroup of 53 patients achieving ypN0, postmastectomy radiotherapy improved locoregional recurrence-free survival (a 5-year rate of 94.7% vs. 72.9%), distant metastasis-free survival (a 5-year rate of 92.8% vs. 75%) and disease-free survival (a 5-year rate of 92.9% vs. 62.5%). By univariate analysis, postmastectomy radiotherapy was the only significant prognostic factor affecting locoregional recurrence-free survival. CONCLUSIONS For patients with clinical T1-2N1 disease, postmastectomy radiotherapy could significantly improve locoregional recurrence-free survival after primary systemic treatment and be even more therapeutic in the subgroup of patients with good response for primary systemic treatment by improving locoregional recurrence-free, distant metastasis-free and disease-free survival. Larger prospective studies are needed to confirm our findings.

Abstract
OBJECTIVES Sarcopenia, defined as an age-associated loss of skeletal muscle function and muscle mass, occurs in approximately 6 - 22 % of older adults. This paper presents evidence-based clinical practice guidelines for screening, diagnosis and management of sarcopenia from the task force of the International Conference on Sarcopenia and Frailty Research (ICSFR). METHODS To develop the guidelines, we drew upon the best available evidence from two systematic reviews paired with consensus statements by international working groups on sarcopenia. Eight topics were selected for the recommendations: (i) defining sarcopenia; (ii) screening and diagnosis; (iii) physical activity prescription; (iv) protein supplementation; (v) vitamin D supplementation; (vi) anabolic hormone prescription; (vii) medications under development; and (viii) research. The ICSFR task force evaluated the evidence behind each topic including the quality of evidence, the benefit-harm balance of treatment, patient preferences/values, and cost-effectiveness. Recommendations were graded as either strong or conditional (weak) as per the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Consensus was achieved via one face-to-face workshop and a modified Delphi process. RECOMMENDATIONS We make a conditional recommendation for the use of an internationally accepted measurement tool for the diagnosis of sarcopenia including the EWGSOP and FNIH definitions, and advocate for rapid screening using gait speed or the SARC-F. To treat sarcopenia, we strongly recommend the prescription of resistance-based physical activity, and conditionally recommend protein supplementation/a protein-rich diet. No recommendation is given for Vitamin D supplementation or for anabolic hormone prescription. There is a lack of robust evidence to assess the strength of other treatment options.

Abstract
OBJECTIVE Hypoxia has been shown to inhibit reactive oxygen species (ROS) production in nucleus pulposus (NP) cells. The TP53-induced glycolysis and apoptosis regulator (TIGAR) has been reported to suppress oxidative stress. We sought to explore the role of TIGAR in the effect of hypoxia on ROS production and apoptosis. METHODS An intervertebral disc degeneration (IDD) model of Sprague-Dawley (SD) rat caudal spine was established by puncturing the Co6-7 disc. TIGAR expression was detected by immunohistochemistry and western blotting in human and SD rat NP tissues of degenerated discs. Rat primary NP cells treated with hypoxia and cobalt chloride (CoCl2) were analyzed by western blotting for TIGAR expression. After TIGAR silence with TIGAR siRNA transfection, apoptosis percentage, mitochondrial and total intracellular ROS levels were measured. H2O2 was used to further check the effects of TIGAR on oxidative stress. Finally, NADPH/NADP+ and GSH/GSSH ratio were examined after TIGAR silencing under hypoxic conditions and after H2O2 treatment. RESULTS A degree-dependent increase in TIGAR expression was observed in human and rat degenerated NP tissues. Hypoxia and hypoxia-inducer CoCl2 enhanced TIGAR and P53 expressions in rat NP cells. TIGAR silence reversed the inhibitory effects of hypoxia on intracellular and mitochondrial ROS production, as well as apoptosis percentage. However, TIGAR silence aggravated H2O2-induced ROS production. In addition, TIGAR increased NADPH/NADP+ and GSH/GSSH ratio in NP cells. CONCLUSIONS These results suggested that TIGAR appears to mediate the protective role of hypoxia on ROS production and apoptosis percentage by enhancing NADPH/NADP+ and GSH/GSSH ratio.

Abstract
Anemia is characteristic of myelodysplastic syndromes (MDS). The mechanisms of anemia in MDS are unclear. Using a mouse genetic approach, here we show that dual deficiency of mDia1 and miR-146a, encoded on chromosome 5q and commonly deleted in MDS (del(5q) MDS), causes an age-related anemia and ineffective erythropoiesis mimicking human MDS. We demonstrate that the ageing bone marrow microenvironment is important for the development of ineffective erythropoiesis in these mice. Damage-associated molecular pattern molecules (DAMPs), whose levels increase in ageing bone marrow, induced TNFα and IL-6 upregulation in myeloid-derived suppressor cells (MDSCs) in mDia1/miR-146a double knockout mice. Mechanistically, we reveal that pathologic levels of TNFα and IL-6 inhibit erythroid colony formation and differentially affect terminal erythropoiesis through reactive oxygen species-induced caspase-3 activation and apoptosis. Treatment of the mDia1/miR-146a double knockout mice with all-trans retinoic acid, which promoted the differentiation of MDSCs and ameliorated the inflammatory bone marrow microenvironment, significantly rescued anemia and ineffective erythropoiesis. Our study underscores the dual roles of the ageing microenvironment and genetic abnormalities in the pathogenesis of ineffective erythropoiesis in del(5q) MDS.

Abstract
Some previous studies and meta-analysis investigated the association between ACE I/D polymorphism and allergic rhinitis risk. However, the results were conflicting. This meta-analysis, therefore, was performed to evaluate the association between ACE I/D polymorphism and allergic rhinitis risk. Online electronic databases (PubMed and EMBASE) were searched. The strength was evaluated by calculating the OR and 95% CI. Five studies were finally included in this meta-analysis. These studies included 681 cases and 629 controls. ACE I/D polymorphism was significantly associated with allergic rhinitis risk (OR = 1.17; 95% CI 1.07 - 1.29; P = 0.001). In the subgroup analysis of race, Asians showed the increased allergic rhinitis risk (OR = 1.15; 95% CI 1.02 - 1.30; P = 0.03). In a stratified analysis by age, adults with ACE I/D polymorphism showed the increased allergic rhinitis risk (OR = 1.16; 95% CI 1.04 - 1.29; P = 0.006). However, children did not have the significantly increased allergic rhinitis risk (OR = 1.24; 95% CI 0.99 - 1.56; P = 0.06). In conclusion, this meta-analysis indicated that ACE I/D polymorphism was significantly associated with allergic rhinitis risk.

Abstract
The glioblastoma includes brain tumors, which are very aggressive in nature and are among the most common brain tumors in adults. Latest therapeutic avenues involve combination approach. However, the observed median survival is still no more than 15 months. Moreover, there is a scarcity of accurate pre-clinical model systems, which in turn resulted in limited treatment options for this disease. Cancer stem cells are attractive avenues in anticancer research against glioblastoma. Most of the recent studies are focused towards the identification of novel markers for cancer stem cells. The present review article is focused on two important markers in current research viz. Prominin-1 and NPM1 in glioblastoma.

Abstract
OBJECTIVES The lack of effective treatment for cartilage defects has prompted investigations using tissue engineering techniques for their regeneration and repair. The success of tissue-engineered repair of cartilage may depend on the rapid and efficient adhesion of transplanted cells to a scaffold. Our aim in this study was to repair full-thickness defects in articular cartilage in the weight-bearing area of a porcine model, and to investigate whether the CD44 monoclonal antibody biotin-avidin (CBA) binding technique could provide satisfactory tissue-engineered cartilage. METHODS Cartilage defects were created in the load-bearing region of the lateral femoral condyle of mini-type pigs. The defects were repaired with traditional tissue-engineered cartilage, tissue-engineered cartilage constructed with the biotin-avidin (BA) technique, tissue-engineered cartilage constructed with the CBA technique and with autologous cartilage. The biomechanical properties, Western blot assay, histological findings and immunohistochemical staining were explored. RESULTS The CBA group showed similar results to the autologous group in biomechanical properties, Moran's criteria, histological tests and Wakitani histological scoring. CONCLUSIONS These results suggest that tissue-engineered cartilage constructed using the CBA technique could be used effectively to repair cartilage defects in the weight-bearing area of joints.Cite this article: H.

Abstract
An image converter based on an indium phosphide has been developed to measure the two-dimensional spatial profile of the incident photon flux by probing the rapid change of the refractive index in the semiconductor. The spatial resolution, dynamic range, and temporal response of this image converter have been investigated with optical methods. The results show that the spatial resolution is ∼15 cycles/mm at the percent modulation transfer function of 0.5, the dynamic range is about 100, and the time response is in the order of 600 ps. This scheme can provide an alternative choice as an imaging diagnostic for experiments in the area of high-energy density physics.

Abstract
Disease recurrence is the major problem in the treatment of acute myeloid leukemia (AML). Relapse is driven by leukemia stem cells, a chemoresistant subpopulation capable of re-establishing disease. Patients with p53 mutant AML are at an extremely high risk of relapse. B-cell-specific Moloney murine leukemia virus integration site 1 (BMI-1) is required for the self-renewal and maintenance of AML stem cells. Here we studied the effects of a novel small molecule inhibitor of BMI-1, PTC596, in AML cells. Treatment with PTC596 reduced MCL-1 expression and triggered several molecular events consistent with induction of mitochondrial apoptosis: loss of mitochondrial membrane potential, BAX conformational change, caspase-3 cleavage and phosphatidylserine externalization. PTC596 induced apoptosis in a p53-independent manner. PTC596 induced apoptosis along with the reduction of MCL-1 and phosphorylated AKT in patient-derived CD34+CD38low/− stem/progenitor cells. Mouse xenograft models demonstrated in vivo anti-leukemia activity of PTC596, which inhibited leukemia cell growth in vivo while sparing normal hematopoietic cells. Our results indicate that PTC596 deserves further evaluation in clinical trials for refractory or relapsed AML patients, especially for those with unfavorable complex karyotype or therapy-related AML that are frequently associated with p53 mutations.

Abstract
BACKGROUND In recent years, the number of randomized controlled trials (RCTs) in the field of orthopaedics is increasing in Mainland China. However, randomized controlled trials (RCTs) are inclined to bias if they lack methodological quality. Therefore, we performed a survey of RCT to assess: (1) What about the quality of RCTs in the field of orthopedics in Mainland China? (2) Whether there is difference between the core journals of the Chinese department of orthopedics and Orthopaedics Traumatology Surgery & Research (OTSR). MATERIAL AND METHODS This research aimed to evaluate the methodological reporting quality according to the CONSORT statement of randomized controlled trials (RCTs) in seven key orthopaedic journals published in Mainland China over 5 years from 2010 to 2014. All of the articles were hand researched on Chongqing VIP database between 2010 and 2014. Studies were considered eligible if the words "random", "randomly", "randomization", "randomized" were employed to describe the allocation way. Trials including animals, cadavers, trials published as abstracts and case report, trials dealing with subgroups analysis, or trials without the outcomes were excluded. In addition, eight articles selected from Orthopaedics Traumatology Surgery & Research (OTSR) between 2010 and 2014 were included in this study for comparison. The identified RCTs are analyzed using a modified version of the Consolidated Standards of Reporting Trials (CONSORT), including the sample size calculation, allocation sequence generation, allocation concealment, blinding and handling of dropouts. RESULTS A total of 222 RCTs were identified in seven core orthopaedic journals. No trials reported adequate sample size calculation, 74 (33.4%) reported adequate allocation generation, 8 (3.7%) trials reported adequate allocation concealment, 18 (8.1%) trials reported adequate blinding and 16 (7.2%) trials reported handling of dropouts. In OTSR, 1 (12.5%) trial reported adequate sample size calculation, 4 (50.0%) reported adequate allocation generation, 1 (12.5%) trials reported adequate allocation concealment, 2 (25.0%) trials reported adequate blinding and 5 (62.5%) trials reported handling of dropouts. There were statistical differences as for sample size calculation and handling of dropouts between papers from Mainland China and OTSR (P<0.05). CONCLUSION The findings of this study show that the methodological reporting quality of RCTs in seven core orthopaedic journals from the Mainland China is far from satisfaction and it needs to further improve to keep up with the standards of the CONSORT statement. LEVEL OF EVIDENCE Level III case control.

Abstract
BACKGROUND In the past decade, researchers have made great progress in the field of Orthopedics. However, the research status of different countries is unclear. To summarize the number of published articles, we assessed the cumulative impact factors in top orthopedic journals. The aims of the study were to measure: 1) the quality and quantity of publications in orthopedics-related journals from China and other five counties, 2) the trend of the number of publications in orthopedics-related journals. METHODS The related journals were selected based on the 2014 scientific citation index (SCI) and articles were searched based on the PubMed database. To assess the quantity and quality of research output, the number of publications including clinical trials, randomized controlled trials, meta-analyses, case reports, reviews, citations, impact factors, number of articles in the top 10 journals and most popular journals were recorded. RESULTS A total of 143,138 orthopedics articles were published from 2005 to 2014. The USA accounts for 24.9% (35,763/143,138) of the publications, followed by UK (7878/143,138 (5.5%)), Japan (7133/143,138 (5.0%)), Germany (5942/143,138 (4.2%)), China (4143/143,138 (2.9%)) and France (2748/143,138 (1.9%)). The ranking for accumulated impact factors as follows: USA, UK, Japan, Germany, France and China. The mean impact factor's order is USA, China, Germany, Japan, France, UK, and interestingly the mean impact factors in Japan is similar to the Germany in 2005-2014. The USA had the highest percentage of articles in the top 10 journals, while China owns the least. The USA had the highest number of average citations, while Japan had lowest number of average citations. CONCLUSIONS According to this study, we can conclude that the USA has had been leading the orthopedics research in the past 10 years. Although China still falls behind, it has made considerable progress in the orthopedics research, not only in quantity but also quality. LEVEL OF EVIDENCE IV.

Abstract
In order to withstand rapid increase in particle and power impact onto the divertor and demonstrate the feasibility of the ITER design under long pulse operation, the upper divertor of the EAST tokamak has been upgraded to actively water-cooled, ITER-like tungsten mono-block structure since the 2014 campaign, which is the first attempt for ITER on the tokamak devices. Therefore, a new divertor Langmuir probe diagnostic system (DivLP) was designed and successfully upgraded on the tungsten divertor to obtain the plasma parameters in the divertor region such as electron temperature, electron density, particle and heat fluxes. More specifically, two identical triple probe arrays have been installed at two ports of different toroidal positions (112.5-deg separated toroidally), which can provide fundamental data to study the toroidal asymmetry of divertor power deposition and related 3-dimension (3D) physics, as induced by resonant magnetic perturbations, lower hybrid wave, and so on. The shape of graphite tip and fixed structure of the probe are designed according to the structure of the upper tungsten divertor. The ceramic support, small graphite tip, and proper connector installed make it possible to be successfully installed in the very narrow interval between the cassette body and tungsten mono-block, i.e., 13.5 mm. It was demonstrated during the 2014 and 2015 commissioning campaigns that the newly upgraded divertor Langmuir probe diagnostic system is successful. Representative experimental data are given and discussed for the DivLP measurements, then proving its availability and reliability.

Abstract
OBJECTIVE To analyze the value of postoperative C-reactive protein (CRP) in predictive diagnosis of postoperative intra-abdominal septic complications (IASC) for patients with Crohn disease (CD). METHODS Clinical data of patients with CD received intestinal resection and anastomosis surgery at Research Institute of General Surgery, Jinling Hospital from January 2011 to January 2015 were analyzed. Patients were divided into two groups by whether suffer from IASC 1 month after surgery, including IASC group and no-IASC group. Propensity score matching method was used to match the general clinical data. A total of 54 patients were analyzed, including IASC 17 cases, no-IASC 37 cases. Postoperative CRP at 1-day and 3-day were compared between the two groups using t test. Receiver operator characteristic (ROC) cure was used to analyze the value of postoperative CRP in predictive diagnosis of IASC. RESULTS IASC group had higher levels of CRP at 1-day ((78±13) mg/L vs. (54±19) mg/L, t=4.633, P=0.000) and 3-day ((103±19) mg/L vs. (69±21) mg/L, t=5.859, P=0.000) after surgery than no-IASC group. ROC analysis showed that the CRP 3-day after surgery cut-off point value of 81.45 mg/L, as used for the predictive diagnosis of IASC, provided a sensitivity of 94.1%, a specificity of 82.9%, an area under the curve of 0.90, better than CRP 1-day after surgery. CONCLUSION Postoperative CRP can be used as a predictive diagnosis of IASC for CD patients received intestinal resection and anastomosis surgery.

Abstract
Background Psoriasis is a chronic inflammatory disease of the skin and joints that may also have systemic inflammatory effects, including the development of cardiovascular disease (CVD). Multiple epidemiologic studies have demonstrated increased rates of CVD in psoriasis patients, although a causal link has not been established. A growing body of evidence suggests that sub-clinical systemic inflammation may develop in psoriasis patients, even from a young age. We aimed to evaluate the prevalence of atherosclerosis and identify specific clinical risk factors associated with early vascular inflammation. Methods We conducted a cross-sectional study of a tertiary care cohort of psoriasis patients using coronary artery calcium (CAC) score and carotid intima-media thickness (CIMT) to detect atherosclerosis, along with high sensitivity C-reactive protein (hsCRP) to measure inflammation. Psoriasis patients and controls were recruited from our tertiary care dermatology clinic. Presence of atherosclerosis was defined using validated numeric values within CAC and CIMT imaging. Descriptive data comparing groups was analyzed using Welch’s t test and Pearson Chi square tests. Logistic regression was used to analyze clinical factors associated with atherosclerosis, and linear regression to evaluate the relationship between psoriasis and hsCRP. Results 296 patients were enrolled, with 283 (207 psoriatic and 76 controls) having all data for the hsCRP and atherosclerosis analysis. Atherosclerosis was found in 67.6 % of psoriasis subjects versus 52.6 % of controls; Psoriasis patients were found to have a 2.67-fold higher odds of having atherosclerosis compared to controls [95 % CI (1.2, 5.92); p = 0.016], after adjusting for age, gender, race, BMI, smoking, HDL and hsCRP. In addition, a non-significant trend was found between HsCRP and psoriasis severity, as measured by PASI, PGA, or BSA, again after adjusting for confounders. Conclusions A tertiary care cohort of psoriasis patients have a high prevalence of early atherosclerosis, increased hsCRP, and psoriasis remains a risk factor for the presence of atherosclerosis even after adjustment of key confounding clinical factors. Psoriasis may contribute to an accelerated systemic inflammatory cascade resulting in increased risk of CVD and CV events.

Abstract
The dietary supplement and adrenergic receptor agonist ephedrine has been a controversial topic as its safety has been questioned. b-adrenergic receptor (b-AR) activation causes immunomodulation, which may contribute to promotion of autoimmune pathology. This report investigated the ability of ephedrine to exacerbate processes associated with autoimmune disease in a lupus-prone mouse model. To mimic human supplementation, ephedrine was administered to NZM391 (lupus-prone) and BALB/c (nonlupus prone) mice orally twice a day for three months at a dose of 50 and 100 mg/day. Some ephedrine-treated NZM391 mice also were preadministered the b-AR antagonist propranolol to investigate b-AR involvement. Mice were bled monthly, and sera were assayed for a variety of lupus manifestations and immunological measurements. In NZM391 males and females, both doses of ephedrine significantly increased lupus manifestations, including IgG production and organ-directed autoantibody titers, and significantly lowered the ratio of IgG2a/IgG1 compared to controls. Ephedrine significantly decreased female lifespan and significantly increased circulating populations of plasma cells (CD38hi CD19lo cytoplasmic IgG+) and CD40+ B1a cells, while preventing an age-related decrease in the B1a cell population expressing a high level of CD5. While ephedrine induced gender-specific immunomodulation in BALB/c mice, increases in the lupus manifestations of anti-dsDNA titers and serum urea nitrogen were not detected. Preadministration of propranolol decreased lupus manifestations and serum levels of IgG and IgE in ephedrine-treated mice, but did not block the shift towards IgG1 production. These findings indicate that ephedrine via b-AR can exacerbate lupus symptoms in NZM391 mice and that blockade of the b-ARs on B cells, and not T cells, apparently was of greater importance as the inhibition of lupus symptoms corresponded to an inhibition of immunoglobulin levels, not a change of Th1/Th2 balance.

Abstract
The human Hole gene (hHole) encodes a six-transmembrane protein with 319- amino acids. Our previous study showed that hHole was strongly expressed in adult heart and may act as a suppressor of extracellular signal-regulated kinases (ERKs), overactivation of which contributed to pathological cardiac hypertrophy. In this study, it was observed that Hole expression was up-regulated in murine hypertrophic hearts. In a cardiac specific transgenic mouse model, it was observed that overexpression of hHole specifically in heart attenuated cardiac hypertrophy and fibrosis induced by isoproterenol (ISO), with blunted transcriptions of ERK1/2, total ERK1/2 proteins and phosphorylated ERK1/2 (p-ERK1/2) levels. Furthermore, overexpression of hHole in mice by hydrodynamic tail-vein injection with hHole plamids also inhibited cardiac hypertrophy induced by ISO. Our work identified hHole as a novel repressor of cardiac hypertrophy, and provided new insights into the possible target for the prevention or treatment of cardiac diseases.

Abstract
The signaling pathway that mediates the anti-inflammatory effects of perfluorocarbon (PFC) in alveolar epithelial cells treated with lipopolysaccharide (LPS) remains unclear. To evaluate the role of macrophage-inflammatory protein-2 (MIP-2), four A549 treatment groups were utilized: (1) untreated control, (2) 10 μg/mL of LPS, (3) 10 μg/mL of LPS+30% PFC and (4) 30% PFC. MIP-2 mRNA expression was determined by qPCR and ELISA. Mitogen-activated protein kinase (MAPK) activation was determined by Western blot analysis, and MIP-2 expression was determined by qPCR following treatment with MAPK inhibitors. PFC suppressed LPS-induced MIP-2 mRNA levels (P≤0.035) and MIP-2 secretion (P≤0.046). LPS induced ATF-2 and c-Jun phosphorylation, which was suppressed by PFC. Finally, inhibitors of ERK, JNK, and p38 suppressed LPS-induced MIP-2 mRNA expression. Thus, PFC inhibits LPS-induced MIP-2 expression and ATF-2 and c-Jun phosphorylation. To fully explore the therapeutic potential of PFC for acute lung injury (ALI), in vivo analyses are required to confirm these effects.

Abstract
We introduce a new type of cluster beam source based on the assembly of (metal) clusters within a condensed (rare gas) matrix. The "Matrix Assembly Cluster Source" employs an ion beam to enhance collisions between metal atoms in the matrix and to sputter out clusters to form a beam. We demonstrate the formation and deposition of gold and silver nanoclusters with mean size tunable from a few atoms to a few thousand atoms. The cluster flux is equivalent to a current nanoAmp regime but potentially scalable to milliAmps, which would open up a number of interesting experiments and applications.

Abstract
Although genetic predisposition plays a major role in the progression of systemic lupus erythematosus (SLE) and its variation in symptoms, the precise relationships between genetic changes and disease status are not well understood. Here, to demonstrate the effect of a single gene mutation on disease etiology, we examined two mouse models of SLE with the same genetic background but different Fas genes. Mice with the Fas(lpr) gene developed severe SLE with renal dysfunction and inflammatory responses in the lung and kidney. By contrast, mice with the Fas(+) gene showed disease-related abnormalities in the liver and joints. Patterns of inflammatory disease markers differed across organs between the two lines of mice. Fas(lpr) mice showed greater MMP signals in the kidney and IL-11 signals in the lung than Fas(+) mice. Fas(+) mice had higher IL-11 signal intensity in the knee region and higher CXCR4 signal intensity in the liver than Fas(lpr) mice. Our results exemplify the complexity of disease and suggest the need for individualized target-specific treatment regimens. Strengths and Limitations of this Study: Fas gene is a well characterized gene in this disease. The molecular components in human disease need more clinical data.

Abstract
OBJECTIVE To evaluate the efficacy and safety of topical 5-aminolevulinic acid (ALA) mediated photodynamic therapy (PDT) for the treatment of severe acne vulgaris. PATIENTS AND METHODS A total of 125 patients with Pillsbury III-IV severe facial acne were treated with 3 courses of ALA-PDT with an interval of 2 weeks. ALA gel (3.6%) was applied topically to acne lesions for 1.5 h. The lesions were irradiated by a LED light of 633 nm with a light intensity of 66 mW/cm² and a light dose of 126 J/cm². Patients were evaluated for efficacy and safety at weeks 2, 4, 6, 8, 12 after the initial treatment. RESULTS The total effective rates were 1.6%, 24.8%, 68.8%, 89.6% and 88.8% at the 2- 4- 6- 8- and 12-week after the initial treatment respectively. The clinical outcomes were the best at 4 weeks after the final treatment. The best effective rate and cure rate were 89.6% and 44% respectively. 26 patients and 16 patients showed apparent exacerbation of acne lesions before the 2nd and 3rd treatment respectively, but all of them showed good or excellent improvement after 3-course treatment. Adverse reactions were mild and transient. CONCLUSIONS 3.6% ALA-PDT is a simple, safe and effective therapeutic option for the treatment of severe acne vulgaris.
