Abstract
The association between prolonged cold ischemic time (CIT) and graft and patient outcomes in live donor kidney transplant recipients remains unclear. The aims of this study were to examine the association of CIT with delayed graft function and graft loss in live donor kidney transplant recipients and those who participated in the Australian Paired Kidney Exchange program using data from the Australia and New Zealand Dialysis and Transplant (ANZDATA) registry. Of 3717 live donor transplant recipients between 1997 and 2012 who were followed for a median of 6.6 years (25 977 person-years), 224 (25%) experienced CIT >4-8 h. Donor age was an effect modifier between CIT and graft outcomes. In recipients who received kidneys from older donors aged >50 years, every hour of increase in CIT was associated with adjusted odds of 1.28 (95% confidence interval [CI] 1.07-1.53, p = 0.007) for delayed graft function, whereas CIT >4-8 h was associated with adjusted hazards of 1.93 (95% CI 1.21-3.09, p = 0.006) and 1.91 (95% CI 1.05-3.49, p = 0.035) for overall and death-censored graft loss, respectively, compared with CIT of 1-2 h. Attempts to reduce CIT in live donor kidney transplants involving older donor kidneys may lead to improvement of graft outcomes.

Abstract
This study aims to determine the effects of alfalfa supplementation on the pre- and postweaning performance, rumen development, and feed transition in starter diet-fed lambs. Six of 66 male Hu lambs were slaughtered at the age of 10 d to serve as a control. The other 60 lambs were randomly allocated to 2 dietary treatments: milk replacer and starter pellets without (STA) or with free-choice chopped alfalfa (S-ALF). The animals were offered 300 g/d of the concentrate mixture and had free access to alfalfa after weaning at the end of wk 4 (age 38 d). The alfalfa inclusion in the S-ALF group tended to increase the starter intake before weaning, significantly increased the concentrate intake soon after weaning ( < 0.05), and increased the BW ( < 0.01) and ADG ( < 0.10) in pre- and postweaning lambs. The S-ALF group had heavier carcasses ( < 0.05), rumens ( < 0.05), reticula ( < 0.05), omasums ( < 0.10), abomasums ( < 0.05), and visceral organs ( < 0.10) than the STA lambs after weaning. Alfalfa supplementation increased ( < 0.05) the rumen papillae length and the ratio of the duodenal villus height to the crypt depth; it also decreased ( < 0.05) the concentration and molar proportion of propionate in wk 1 and 5. The STA lambs had higher ( < 0.01) blood concentrations of globulin and blood urea nitrogen and lower β-hydroxybutyrate after weaning. The STA group also had a higher incidence of feed plaque. From the above results, we infer that the free-choice addition of chopped alfalfa to starter diets is beneficial to rumen development, relieves weaning stress, and improves the performance of lambs.

Abstract
OBJECTIVE To verify the safety and efficacy of the domestic 3D cardiac electrophysiological mapping system for catheter ablation of persistent atrial fibrillation (AF). METHODS From December 2011 to April 2014, 255 patients (184 male) with persistent AF in 13 centers were enrolled in this multicenter prospective controlled study.The patients were allocated to catheter ablation group (experiment group) and antiarrhythmics drugs cardioversion group (control group) with the ratio 2∶1 according to the patients' intention. Left atria were constructed with 3D cardiac electrophysiology mapping system, magnetic sensored saline irrigated radiofrequency ablation catheter (FireMagic™ Cool 3D) and surface reference (Columbus™). Pulmonary vein isolation and left atrial roof line, mitral annulus isthmus line, three tricuspid annulus isthmus line, superior vena cava, the coronary sinus and complex atrial fragmented potentials were targeted if necessary under the guidance of the 3D mapping system. Antiarrhythmics drugs (except amiodarone) were applied to patients for 2 to 3 months after ablation. The patients were followed up for 9 months after 3 months blanking period. The patients in the control group underwent cardioversion with amiodarone and electrical cardioversion if needed. Patients in the control group were also followed up for 9 months. RESULTS Of the 255 patients, 167 cases were in the experiment group and 88 cases were in the control group. In per protocol set (PPS), 155 cases were in the experiment group, 79 cases in the control group. Catheter ablation was successful for all patients in the experiment group under the guidance of the 3D cardiac electrophysiological mapping system. Pumononary veins isolation was achieved in all patients. After 9 months follow-up beyond blanking period, in full analysis set, the success rate was 66.5% (111/167) in the experiment group, which was significantly higher than that in the control group (21.6% (19/88), P<0.001). In PPS, the success rate was also significantly higher in the experiment group than in the control group (67.1% (104/155) vs. 22.8%(18/79), P<0.001). The incidence of adverse events was 19.8% in the experiment group and 13.6% in the control group(P=0.223). The adverse events associated with catheter ablation included 1 case of left subclavian hematoma, 1 case of left subclavian bleeding and 1 case of pericardial effusion, which was alleviated by pericardiocentesis. No pulmonary vein stenosis occurred. CONCLUSION Domestic 3D cardiac electrophysiological mapping system can safely and effectively guide catheter ablation of persistent AF.

Abstract
UNLABELLED Many previous studies have reported excellent clinical results with percutaneous kyphoplasty (PKP). In contrast, numerous complications and problems have also been reported, such as puncture difficulty, cement leakage, and adjacent vertebral fracture. INTRODUCTION This study is to evaluate the application and clinical outcomes of unilateral transverse process-pedicle and bilateral PKP in the treatment of osteoporotic vertebral compression fractures (OVCF). METHODS A total of 56 cases with two levels thoracolumbar OVCF were randomly assigned for treatment with unilateral transverse process-pedicle and bilateral PKP. The patients were followed up postoperatively and were assessed mainly with regard to clinical and radiologic outcomes. Clinical outcomes were evaluated with mainly the use of a visual analogue scale (VAS) for pain. Radiologic outcomes were assessed mainly on the basis of radiation dose and bone cement distribution. RESULTS The operation was completed successfully in 56 cases. In the unilateral level, the operation time, the volume of the injected cement, and radiation dose were significantly less than bilateral level. All patients had significantly improvement on VAS score after the procedures, compared with their preoperative period. In the bilateral level, 7 patients had obvious pain in the puncture sites at 1 month postoperatively caused by facet joint violation. With local block treatment, the pain disappeared in all patients at the last follow-up. CONCLUSION Both bilateral and unilateral PKP are relatively safe and effective treatments for patients with painful OVCF. But unilateral PKP received less radiation dose and operation time, offered a higher degree of deformity correction, and resulted in less complication than bilateral.

Abstract
Subarachnoid hemorrhage (SAH) is a devastating disease with high mortality. The mechanisms underlying its pathological complications have not been fully identified. Here, we investigate the potential involvement of the glymphatic system in the neuropathology of SAH. We demonstrate that blood components rapidly enter the paravascular space following SAH and penetrate into the perivascular parenchyma throughout the brain, causing disastrous events such as cerebral vasospasm, delayed cerebral ischemia, microcirculation dysfunction and widespread perivascular neuroinflammation. Clearance of the paravascular pathway with tissue-type plasminogen activator ameliorates the behavioral deficits and alleviates histological injury of SAH. Interestingly, AQP4−/− mice showed no improvements in neurological deficits and neuroinflammation at day 7 after SAH compared with WT control mice. In conclusion, our study proves that the paravascular pathway dynamically mediates the pathological complications following acute SAH independently of glymphatic control.

Abstract
Abstract
Introduction: RATHER (Rational Therapy for Breast Cancer) is an international multi-site collaborative effort that aims to use high resolution molecular profiling techniques to identify novel kinase targets for two subtypes of breast cancer, invasive lobular cancers (ILC) and triple negatives (TN) where no targeted therapies are available at present.
Experiments: DNA, RNA and protein were extracted from 137 ILC and 155 TN samples with an average of 5 years clinical follow-up. A variety of high resolution molecular profiling methods were used such as copy number analysis (Affymetrix SNP6), gene expression profiling (Agilent 4x44K gene arrays), targeted sequencing (Agilent customized kinome panel & Illumina Nextera Custom Enrichment), whole transcriptomic sequencing and reverse phase protein lysate array (RPPA) analysis.
Results: Combining copy number and gene expression data, we have classified the ILC tumors into the intergrative Cluster (IntClust) subgroups that we have previously identified from our large-scale breast cancer study, METABRIC (Molecular Taxonomy of Breast Cancer International Consortium). The ILC tumors were predominantly in IntClust3 (37.2%) and IntClust8 (21.2%). Only two genes were found to be frequently mutated (>10%) ie. CDH1 (40.8%) and PIK3CA (35%ILC). The PI3K pathway has been found to be frequently altered in ILCs by either mutations (PIK3CA and AKT1) or copy number alterations (PTEN). Integrating with transcriptomic and proteomic data, two main subtypes of ILCs were identified: (i) an immune responsive subtype with mRNA up-regulation of PDL1, PD1 and CTLA4 and greater sensitivity to DNA-damaging agents in representative cell line models; (ii) a hormone receptor signalling subtype, associated with Epithelial to Mesenchymal Transition (EMT), and gain of chromosomes 1q and 8q and loss of chromosome 11q. Using somatic mutation rate and eIF4B protein level, we identified three groups with different clinical outcomes, including a group with extremely good prognosis.
Conclusion: We provide a comprehensive overview of the molecular alterations driving ILC and have explored links with therapy response. This molecular characterization will help to tailor treatment of ILC through the application of specific targeted, chemo- and/or immune-therapies.

Abstract
OBJECTIVE To investigate the effect of renal clearance on serum trough concentration of vancomycin in elderly patients with severe pneumonia. METHODS This was a prospective non-interventional study. Forty-two elderly patients with severe pneumonia and normal level of serum creatinine were enrolled from November 2013 to October 2014. The patients included 25 males and 17 females, aged 60-83 years (median 74 years). The renal clearance was measured, and the vancomycin regimen and rate of serum trough concentration achieving guideline-recommended target of 15-20 mg/L were investigated. The factors influencing trough concentration of vancomycin were analyzed using the general linear model. RESULTS The vancomycin regimens were 1 g/ 12 h (17 cases), 0.5 g/8 h (14 cases) and 0.5 g/12 h (11 cases), and their median and range of serum concentrations were 14.9(2.4-28.5)mg/L, 16.2(2.8-27.8)mg/L and 11.6 (5.9-19.9) mg/L, respectively. The guideline-recommended target trough concentration of 15-20 mg/L was reached in only 10 patients, while trough concentration lower than 15 mg/L was found in 22 patients and higher than 20 mg/L in 10 patients. General linear model analysis showed that creatinine clearance rate(CCR) and dose of vancomycin per kilogram of body weight per day were independent influencing factors for trough concentration (both P<0.05). There were 8 patients with CCR≥130 ml·min(-1)·(1.73 m(2))(-1) (augmented renal clearance), 22 patients with 70≤CCR<130 ml·min(-1)·(1.73 m(2))(-1) and 12 patients with CCR<70 ml·min(-1)·(1.73 m(2))(-1,) and vancomycin trough concentration below 15 mg/L was found in 7, 11 and 4 patients, respectively. CONCLUSION CCR was an independent influencing factor for trough concentration of vancomycin, and augmented renal clearance increased the risk of subtherapeutic trough concentration of vancomycin.

Abstract
The emergence of influenza A H7N9 in infection has posed a great threat to public health globally. Poor immunogenicity of H7N9 haemagglutinin (HA) is a major obstacle to the development of an effective H7N9 vaccine. Here, we found that the vaccine containing the H7HA head conjugated with IgG Fc (Hd-Fc) induced strong neutralizing antibody responses and protection against H7N9 infection, whilst the Fc-conjugated H7HA stalk (St-Fc)-based vaccine could not induce neutralizing antibodies, although the St-Fc-immunized mice were partially protected. The vaccines containing the full-length extracellular domain of HA conjugated with Fc and the mixture of Hd-Fc plus St-Fc induced significantly lower neutralizing antibody and haemagglutination inhibition titres than the Hd-Fc-based vaccine. These results suggest that the St-Fc may have inhibitory effects on the neutralizing immunogenicity of Hd-Fc. Therefore, the neutralizing domain(s), such as the receptor-binding domain, in the HA head should be kept and the non-neutralizing domain(s) in the HA stalk with the ability to potentially suppress the neutralizing immunogenicity of HA head should be removed from Fc-conjugated HA-based influenza vaccines to increase the neutralizing antibody response.

Abstract
A nanoparticle with pH-induced fluorescence was reported for intracellular tracking. The fluorescence was evoked by the isomerization of the ring-closed form spiropyran (SP) to the ring-open form merocyanine (MC) in the weak acidic environment of cells. The SP-MC switch accelerated the dissociation of nanoparticles to trigger the release of trapped paclitaxel.

Abstract
Grasshopper plagues have seriously disturbed grassland ecosystems in Inner Mongolia, China. The accurate prediction of grasshopper infestations and control of grasshopper plagues have become urgent needs. We sampled 234, 342, 335, and 369 plots in Xianghuangqi County of Xilingol League in 2010, 2011, 2012, and 2013, respectively, and measured the density of the most dominant grasshopper species, Oedaleus decorus asiaticus, and the latitude, longitude, and associated relatively stable habitat factors at each plot. We used Excel-GeogDetector software to explore the effects of individual habitat factors and the two-factor interactions on grasshopper density. We estimated the membership of each grasshopper density rank and determined the weights of each habitat category. These results were used to construct a model system evaluating grasshopper habitat suitability. The results showed that our evaluation system was reliable and the fuzzy evaluation scores of grasshopper habitat suitability were good indicators of potential occurrence of grasshoppers. The effects of the two-factor interactions on grasshopper density were greater than the effects of any individual factors. O. d. asiaticus was most likely to be found at elevations of 1300-1400 m, flat terrain or slopes of 4-6°, typical chestnut soil with 70-80% sand content in the top 5 cm of soil, and medium-coverage grassland. The species preferred temperate bunchgrass steppe dominated by Stipa krylovii and Cleistogenes squarrosa. These findings may be used to improve models to predict grasshopper occurrence and to develop management guidelines to control grasshopper plagues by changing habitats.

Abstract
Female pigs are commonly utilized as an animal model for biomedical research and require urethral catheterization. Sixteen pigs were anaesthetized for research purposes and required the placement of a urethral catheter. Post-mortem examination of the vaginas revealed the urethral opening to be consistently halfway from the mucocutaneous junction of the vulva to the cervix. A shallow diverticulum was also observed on the ventral floor of the urethral opening. To optimize conditions for success the pig should be carefully positioned supine, a vaginal speculum and light source should be used, the pig should be adequately anaesthetized, and the anatomy of the vagina should be reviewed.

Abstract
The early response to the dehydration 15 (ERD15) gene is widely involved in the processes of signal transduction, programmed cell death, gene transcription, and stress tolerance in plants. In a previous study, the ERD15 gene was shown to be an important regulator of the abscisic acid response and salicylic acid-dependent defense pathway, acting as an important negative regulator of abscisic acid. The complete IbERD15 gene (accession No. KF723428) was isolated by reverse transcription-polymerase chain reaction. The IbERD15 gene contains an open reading frame of 504 bp, encodes a peptide of 167 amino acids, and has a molecular mass of 18.725 kDa. The transcript levels of the IbERD15 gene in a variety of tissues were examined by digital gene expression profiling. The roots of the sweet potato were treated by 3 degrees of polyethylene glycol, and the results indicate that the IbERD15 gene might play an important role in the defense response to drought stress. Moreover, the IbERD15 gene was successfully transformed into yeast cells for analysis of drought tolerance in transgenic yeast.

Abstract
OBJECTIVE To compare the diagnostic capabilities between capsule endoscopy (CE) and multislice CT (MSCT) enterography in combination with MSCT angiography for assessment of obscure gastrointestinal bleeding (OGIB). METHODS A total of 127 patients with OGIB were looked at in this study. 82 patients (aged 42.7 ± 19.1 years; 34 males) were assigned to receive MSCT diagnosis and 67 patients to (aged 53.9 ± 16.2 years; 28 males) receive CE diagnosis. Among them, 22 patients (aged 54.1 ± 19.1 years; 12 males) received both examinations. Oral isotonic mannitol and intramuscular injection of anisodamine were performed; non-ionic contrast (iopromide, 370 mg I ml(-1)) was intravenously administered; and then multiphase scanning was conducted at arterial, small intestinal and portal venous phases in MSCT. The results were compared with findings of reference standards including double balloon enteroscopy, digital subtraction angiography, intraoperative pathological examination and/or clinical diagnosis. RESULTS Administration of anisodamine markedly increased the satisfaction rate of bowel filling (94.67% vs 28.57%; p < 0.001) but not the diagnostic yield (p = 0.293) of MSCT. Compared with MSCT, CE showed an improved overall diagnostic yield (68.66% vs 47.56%; p = 0.010), which was also observed in overt bleeding patients (i.e. patients with continued passage of visible blood) (76.19% vs 51.02%; p = 0.013) and in patients aged younger than 40 years of age (85% vs 51.28%; p = 0.024). However, CE had similar positive rates to MSCT (p > 0.05). Among the 22 cases in whom both examinations were conducted, CE showed no significantly different diagnostic capability compared with MSCT (p = 0.4597). CONCLUSION Both CE and MSCT are safe and effective diagnostic methods for OGIB. ADVANCES IN KNOWLEDGE CE is preferred for overt bleeding or patients aged younger than 40 years. The combined use of CE and MSCT is recommended in OGIB diagnosis.

Abstract
The aim of this study is to develop a novel laparoscopic surgery by extra-peritoneal approach for kidney transplant and pave the way of safe transition from laboratory to the clinic. The study was established to explore the feasibility and safety of human laparoscopic kidney transplant. The experiment was first conducted on the deceased animals, then live animals and human cavader before human kidney transplant was approved. The study patient was a 49-year-old male who received the kidney for laparoscopic kidney transplant by extra-peritoneal approach. The control patient received the contralateral kidney for open kidney transplant. The estimated blood loss was minimal during surgery. Both kidneys experienced delayed graft function but the kidneys started function on Day 6 postoperation. The analgesia consumption was significantly less in the study patient. There is no surgical complication during 6-month follow-up. This study has developed a new technique for laparoscopic kidney transplant by extra-peritoneal approach. It has retained the advantages of open kidney transplant, which allows the graft located in the extra-peritoneal space without violating peritoneum. This study has also paved the way of safe transition for a novel laparoscopic surgery from laboratory to the clinic.

Abstract
Toxoplasma gondii can infect a wide variety of warm-blooded animals, including bats. Limited information on T. gondii infection in bats is available in China. The objective of the present study was to determine prevalence and genetic diversity of T. gondii infection in bats in southern China. A total of 608 bats representing 12 species, including 120 Aselliscus stoliczkanus, 59 Myotis chinensis, 11 Miniopterus schreibersii, 53 Rhinolophus affinis, 32 Rhinolophus pusillus, 81 Hipposideros armiger, 28 Hipposideros fulvus, 32 Cynopterus brachyotis, 14 Cynopterus sphinx, 45 Eonycteris spelaea, 109 Hipposideros larvatus, and 24 Taphozous melanopogon, were collected from Yunnan and Guangxi provinces, southern China. They were examined for the presence of T. gondii DNA by amplification of the B1 gene using a nested PCR, and the positive samples were genotyped at 11 genetic loci (SAG1, 5'- and 3'-SAG2, alternative SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1 and Apico) using multilocus polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technology. Fifty-nine (9.7%) of these bats were detected positive by PCR but only five of these positive DNA samples were completely typed at all loci; of which 4 samples, 2 from A. stoliczkanus, and 2 from H. larvatus, belonged to ToxoDB Genotype #10, and the other one from H. larvatus was identified as ToxoDB Genotype #9 (http://toxodb.org/toxo/). To our knowledge, this is the first report of molecular detection and genetic characterization of T. gondii infection in bats in China. The results show that these bats are potential reservoirs for T. gondii transmission, which may pose a threat to human health.

Abstract
Increased expression of STMN1 has been observed in many tumor forms, but its expression and potential biological role in pancreatic cancer is still unknown. In this study, we demonstrated that STMN1 was expressed to a large extent in pancreatic cancer tissues and cell lines as compared to normal pancreatic tissues. Suppression of STMN1 expression via transfection with STMN1-specific siRNA could not only significantly inhibit the proliferation, migration and invasion ability of Panc-1 cells, but also enhance the apoptosis of Panc-1 cells. In addition, downregulation of STMN1 obviously enhanced the acetylation level of α-tubulin. All these results indicated that STMN1 plays an important role in pancreatic cancer development, and might serve as a potential therapeutic target for pancreatic cancer.

Abstract
INTRODUCTION Following traumatic brain injury (TBI), there may be persistent pituitary deficits despite the presence of normal conventional magnetic resonance (MR) images. Little is known about the association of microstructural changes in the pituitary with pituitary function in TBI patients with normal appearing brain on conventional MR images. Our aim was to quantify changes in pituitary apparent diffusion coefficient (ADC) of normal appearing brain in human traumatic brain injury. METHODS Forty-two patients admitted with a diagnosis of mild head injury having normal appearing brain imaging were scanned at 7 days after injury using a quantitative echo planar imaging acquisition to obtain ADC parametric map. Mean pituitary ADC values were compared with a control group (n = 30). RESULTS The TBI group showed a significant decrease in pituitary ADC compared to the controls. Furthermore, the mean ADC was much less in TBI patients with pituitary dysfunction compared to those with normal pituitary function. There was also a correlation between the development of pituitary dysfunction and decreasing ADC (r = 0.82, P<0.01). CONCLUSION Our findings suggest that pituitary ADC is a sensitive and independent marker of pituitary damage following traumatic insult, which is useful to detect the microstructural damage in pituitary in normal appearing brain.
