Abstract
Bioceramics are versatile materials for hard tissue engineering. Hydroxyapatite (HA) is a widely studied biomaterial for bone grafting and tissue engineering applications. The crystal structure of HA allows for a wide range of substitutions, which allows for tailoring materials properties. Transition metals and lanthanides are of interest since substitution in HA can result in magnetic properties. In this study, experimental results were compared to theoretical calculations of HA substituted with a transition metal. Calculation of a 10 atomic percent substitution of a transition metal ion Mn(2+), Fe(2+), and Co(2+) substituted HA samples lead to magnetic moments of 5, 4, and 3 Bohr magnetons, respectively. Hydroxyapatite substituted by transition metals (MHA) was fabricated through an ion exchange procedure and characterized with X-ray diffraction, Fourier transform infra-red spectroscopy (FTIR), X-ray photoelectron spectroscopy, and vibrating sample magnetometer, and results were compared to theoretical calculations. All the substitutions resulted in phase-pure M(2+)HA with lattice parameters and FTIR spectra in good agreement with calculations. Magnetic measurements revealed that the substitution of Mn(2+) has the greatest effect on the magnetic properties of HA followed by the substitution of Fe(2+) and then Co(2+). The present work underlines the power of synergistic theoretical-experimental work in guiding the rational design of materials.

Abstract
BACKGROUND Chili consumption may have a beneficial effect on muscle strength in the general population. The aim of this study was to investigate the relationship between frequency of chili consumption and handgrip strength in adults. DESIGN Population-based cross-sectional study. SETTING This study used baseline data from the Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study. PARTICIPANTS A total of 3 717 subjects were recruited to the study. Frequency of chili consumption during the previous month was assessed using a valid self-administered food frequency questionnaire. Analysis of covariance was used to examine the relationship between muscle strength and frequency of chili consumption. Handgrip strength was measured using a handheld digital dynamometer. RESULTS After adjustment for potential confounding factors, significant relationships were observed between different categories of chili consumption and handgrip strength in males, the means (95% confidence interval) for handgrip strength across chili consumption categories were 44.7 (42.1, 47.2) for < one time/week; 45.5 (42.9, 48.1) for one time/week; and 45.8 (43.3, 48.4) for ≥ 2-3 times/week (P for trend < 0.01). Similar results were not observed with sweet pepper consumption. CONCLUSIONS This study reveals a positive correlation between frequency of chili consumption and muscle strength in adult males. Further studies are necessary in order to determine whether there is a causal relationship between chili consumption frequency and muscle strength.

Abstract
WHAT IS KNOWN AND OBJECTIVES Current guidelines provide no recommendations on perioperative bridging for patients after mechanical heart valve replacement (MHVR) who also have a history of heparin-induced thrombocytopenia (HIT). We present a successful case of prolonged bridging with fondaparinux in a 69-year-old Chinese woman. CASE SUMMARY The patient presented to our department with the aim for radical resection of oesophageal cancer. Fondaparinux has been administered alone at 2·5 mg subcutaneously once daily for 24 days during the interruption of warfarin perioperatively. There were no signs or symptoms of thromboembolic or bleeding throughout and after her hospitalization. WHAT IS NEW AND CONCLUSION Fondaparinux may offer an option for management of the patients with MHVR who cannot use heparin products, but further clinical investigations are warranted.

Abstract
Microorganisms play important roles in intravascular catheter (IVC)-related infections, which are the most serious complications in children with IVCs, leading to increased hospitalisation, intensive care admissions, extensive antibiotic treatment and mortality. A greater understanding of bacterial communities is needed in order to improve the management of infections. We describe here the systematic culture-independent evaluation of IVC bacteriology in IVC biofilms. Twenty-four IVC samples (six peripherally inserted central catheters, eight central venous catheters and ten arterial catheters) were collected from 24 paediatric patients aged 0 to 14 years old. Barcoded amplicon libraries produced from genes coding 16S rRNA and roll-plate culture methods were used to determine the microbial composition of these samples. From a total of 1,043,406 high-quality sequence reads, eight microbial phyla and 136 diverse microbial genera were detected, separated into 12,224 operational taxonomic units (OTUs). Three phyla (Actinobacteria, Firmicutes and Proteobacteria) predominate the microorganism on the IVC surfaces, with Firmicutes representing nearly half of the OTUs found. Among the Firmicutes, Staphylococcus (15.0% of 16S rRNA reads), Streptococcus (9.6%) and Bacillus (6.1%) were the most common. Community composition did not appear to be affected by patients' age, gender, antibiotic treatment or IVC type. Differences in IVC microbiota were more likely associated with events arising from catheter dwell time, rather than the type of IVC used.

Abstract
Giant panda cubs have a low survival rate during the newborn and early growth stages. However, the growth and developmental parameters of giant panda cubs during the early lactation stage (from birth to 6 months) are not well known. We examined the growth and development of giant panda cubs by the Chapman growth curve model and estimated the heritability of the maximum growth rate at the early lactation stage. We found that 83 giant panda cubs reached their maximum growth rate at approximately 75-120 days after birth. The body weight of cubs at 75 days was 4285.99 g. Furthermore, we estimated that the heritability of the maximum growth rate was moderate (h(2) = 0.38). Our study describes the growth and development of giant panda cubs at the early lactation stage and provides valuable growth benchmarks. We anticipate that our results will be a starting point for more detailed research on increasing the survival rate of giant panda cubs. Feeding programs for giant panda cubs need further improvement.

Abstract
Energy loss in the transport of a beam of relativistic electrons in warm dense aluminum is measured in the regime of ultrahigh electron beam current density over 2×10^{11} A/cm^{2} (time averaged). The samples are heated by shock compression. Comparing to undriven cold solid targets, the roles of the different initial resistivity and of the transient resistivity (upon target heating during electron transport) are directly observable in the experimental data, and are reproduced by a comprehensive set of simulations describing the hydrodynamics of the shock compression and electron beam generation and transport. We measured a 19% increase in electron resistive energy loss in warm dense compared to cold solid samples of identical areal mass.

Abstract
BACKGROUND Primary fallopian tube carcinoma (PFTC) is a rare malignant gynecologic oncology. There was no consensus on the outcome related clinicopathological characteristics. Present study aims to determine the prognosis associate factors in PFTC. MATERIALS AND METHODS In this retrospective study, the authors identified 50 PFTC patients in Jiangsu Institute of Cancer Research and 16 cases in the Affiliated People's Hospital of Inner Mongolia Medical College between 1988 and 2013. Disease surveillance was conducted based on the follow-up protocol of MD Anderson Cancer Center. Cox proportional hazards model and log-rank test were used to assess the associations between potential clinicpathologic characteristics and the survival durations. RESULTS The median progression free survival (PFS) and overall survival (OS) of PFTC were 36.9 and 62.7 months, respectively. FIGO Stage (p < 0.01, 0.01), grade (p = 0.02, 0.03), tumor residual after initial debulking surgery (p = 0.05, 0.01), nadir CA-125 (p = 0.01, 0.01) were independently related with PFS and OS. The PFS and OS of patients with Stage II PFTC were similar as those with Stage III-IV (30.7 vs 28.3 and 61.9 vs 49.2 months, respectively) but poorer than those of Stage I cases (N/A). The PFS of patients with paclitaxel-based chemotherapy was longer than those with other regime (51.3 vs 33.1 months), but not OS (62.7 vs 42.6 months). The outcome of patients underwent optimal initial cytoreduction surgery was better than those of suboptimal ones (PFS 56.4 vs 21.2 months and OS 65.3 vs 47.9 months, respectively). CONCLUSIOn: PFTC patients with FIGO Stage II disease should be regarded as advanced disease. Paclitaxel based chemotherapy was associated with longer PFS but not OS in PFTC.

Abstract
OBJECTIVES The objective of this study was to evaluate the impact of luteinizing hormone (LH), estradiol (E2) and progesterone (P) levels on the day of human chorionic gonadotropin (HCG) administration on outcomes of in vitro fertilization (IVF) in controlled ovarian hyperstimulation (COH). STUDY DESIGN In this retrospective study, 129 infertile women undergoing IVF/intracytoplasmic sperm injection (ICSI) treatments were included; these cycles were stratified according to LH levels of ≥ 1.12 IU/L or < 1.12 U/L and according to E2 levels of ≥ 1,005.89 pmol/L or < 1,005.89 pmol/L. The main outcome measure was the clinical pregnancy rate. RESULTS The clinical pregnancy rate was significantly higher in the group with LH ≥ 1.12 IU/L than in the group with LH < 1.12 U/L (43.28% vs. 30.65%, p < 0.05). The clinical pregnancy rate was also higher in the group with E2 ≥ 1,005.89 pmol/L than in the group with average E2 < 1,005.89 pmol/L (42.86% vs. 30.51%, p < 0.05). Among the LH, E2, and P levels on the day of HCG administration, LH level was the most important predictor of outcomes of IVF in COH. The present data showed an adverse effect of low serum LH level (LH < 1.12 IU/L) on the day of HCG administration on clinical pregnancy rate. E2 level can also predict the outcomes of IVF in COH. CONCLUSIONS Low serum LH level (LH < 1.12 IU/L) and low serum E2 level (average E2 < 1,005.89 pmol/L) on the day of HCG administration led to low clinical pregnancy rates, while the P level on the day of HCG administration may have had little effect on clinical pregnancy.

Abstract
We have developed a new experimental platform at the Linac Coherent Light Source (LCLS) which combines simultaneous angularly and spectrally resolved x-ray scattering measurements. This technique offers a new insights on the structural and thermodynamic properties of warm dense matter. The < 50 fs temporal duration of the x-ray pulse provides near instantaneous snapshots of the dynamics of the compression. We present a proof of principle experiment for this platform to characterize a shock-compressed plastic foil. We observe the disappearance of the plastic semi-crystal structure and the formation of a compressed liquid ion-ion correlation peak. The plasma parameters of shock-compressed plastic can be measured as well, but requires an averaging over a few tens of shots.

Abstract
Recent experiments performed at the Matter in Extreme Conditions end station of the Linac Coherent Light Source (LCLS) have demonstrated the first spectrally resolved measurements of plasmons from isochorically heated aluminum. The experiments have been performed using a seeded 8-keV x-ray laser beam as a pump and probe to both volumetrically heat and scatter x-rays from aluminum. Collective x-ray Thomson scattering spectra show a well-resolved plasmon feature that is down-shifted in energy by 19 eV. In addition, Mbar shock pressures from laser-compressed aluminum foils using velocity interferometer system for any reflector have been measured. The combination of experiments fully demonstrates the possibility to perform warm dense matter studies at the LCLS with unprecedented accuracy and precision.

Abstract
AIM Deep vein thrombosis (DVT) is a major complication that can occur after injuries. our aim was to explore the incidence and risk factors of venous thromboembolism in patients with ankle fractures. METHODS Consecutive patients with an isolated fracture of the ankle presenting at our centre between Sept 2004 and May 2012 were studied. They were investigated for venous thrombosis by Doppler sonography (DUS) before surgery. Univariate and multivariate logistic regressions analyses were performed to identify the incidence and risk factors for venous thromboembolism. RESULTS A total of 2347 patients were studied in the research. Of these, only 119 patients suffered from DVT. The multivariable analyses showed that diabetes, less activity and the time from injury were the key risk factors for thrombosis. CONCLUSION In patients with ankle fracture, the risk of thrombosis was low and it may not need warrant routine thromboprophylaxis. However, most cases had no significant symptoms, is necessary to grasp the indications for high risk patients to reduce the incidence rate of venous thrombosis.

Abstract
The primary limitation of thrombolytic treatment of ischemic stroke with tissue plasminogen activator (tPA) is the hemorrhagic risk. We tested AcSDKP (N-acetyl-seryl-aspartyl-lysyl-proline), as an auxiliary therapeutic agent, to reduce blood-brain barrier (BBB) disruption in a combination tPA thrombolytic treatment of stroke. Wistar rats subjected to embolic stroke were randomly assigned to either the tPA monotherapy group (n=9) or combination of tPA and AcSDKP treatment group (n=9) initiated at 4 h after ischemia. Magnetic resonance imaging (MRI) measurements were performed before and after the treatments. Immunohistochemical staining and measurements were performed to confirm MRI findings. Longitudinal MRI permeability measurements with gadolinium-diethylenetriamine penta-acetic acid (Gd-DTPA) demonstrated that combination treatment of acute embolic stroke with AcSDKP and tPA significantly reduced BBB leakage, compared to tPA monotherapy, at 3 and 6 days (18.3±9.8 mm3 vs. 65.0±21.0 mm3, p<0.001) after the onset of stroke, although BBB leakage was comparable between the two groups prior to the treatments (6.8±4.4 mm3 vs. 4.3±3.3 mm3, p>0.18). The substantial reduction of BBB leakage observed in the combination treatment group was closely associated with reduced ischemic lesions measured by T2 maps (113.6±24.9 mm3 vs. 188.1±60.8 mm3, p<0.04 at 6 days). Histopathological analysis of the same population of rats showed that the combination treatment significantly reduced parenchymal fibrin deposition (0.063±0.059 mm2 vs. 0.172±0.103 mm2, p<0.03) and infarct volume (146.7±35.9 mm3 vs. 199.3±60.4 mm3, p<0.05) compared to the tPA monotherapy at 6days after stroke. MRI provides biological insight into the therapeutic benefit of combination treatment of stroke with tPA and AcSDKP 4h after onset, and demonstrates significantly improved cerebrovascular integrity with neuroprotective effects compared with tPA monotherapy.
