Abstract
Safflower yellow (SY) is an aqueous extract of natural safflower. Our laboratory has reported protective effects of alleviating memory impairment with SY in a transgentic mouse model of Alzheimer's disease. The possible beneficial effects of SY on amyloid-β-induced neuroinflammation in dementia remain unclarified. This study we hypothesize that astrocytes and microglia may cause amyloid-β deposition and produce a neuroinflammatory response, aims to explain the role and mechanism of SY in regulating glial activation and reducing Aβ deposition in Aβ1-42 induced rat model. Wistar rats were treated with SY for one month after bilateral hippocampal injection of aggregated Aβ1-42; behavioral tests were performed to demonstrate the amelioration of cognitive function. After that, the contents of iNOS, IL-1β, IL-6, and TNF-α in AD brain was detected. Western blot and real-time PCR were used to detect the M1 and M2-associated markers to demonstrate the activation of microglia. The conducted experiments have revealed that SY could strengthen spatial learning and memory ability of dementia rats, decrease the contents of iNOS, IL-1β, IL-6, and TNF-α and depress the activation of glial cells. Moreover, the SY treatment inhibited the M1 release of pro-inflammatory cytokines (iNOS and CD86), increased the expression of arginase-1, CD206, and YM-1 thereby reduced inflammation in model rats. Thus our results indicated that SY has very important theoretical and clinical value for the research and development of Chinese medicine for the treatment of AD.

Abstract
Effects of the coccidial vaccination and dietary antimicrobial alternatives on growth performance, internal organ development, and intestinal morphology of male broilers subjected to an Eimeria challenge were determined. A total of 1,120 one d-old Ross × Ross 708 male broilers were randomly distributed to 80 floor pens (10 treatments, 8 replication pens/treatment, and 14 chicks/pen). A 2 × 5 factorial arrangement of treatments was used to determine the main and interaction effects of the coccidial vaccination (vaccinated or non-vaccinated) and the dietary additive [1) corn and soybean-meal basal diet, 2) basal diet + antimicrobials (bacitracin and salinomycin), 3) basal diet + probiotics (3 Bacillus subtilis strains), 4) basal diet + prebiotics (mannan-oligosaccharides and β-glucans), and 5) basal diet + probiotics + prebiotics]. To mimic the Eimeria challenge, all chicks were gavaged with a 20x dose of a different coccidial vaccine (live Eimeria oocysts) at Day 14. The coccidial vaccination decreased Day 0-14 and 29-42 BW gain (BWG) and subsequently decreased Day 0-56 BWG. Broilers fed diets with antimicrobials exhibited the lowest feed conversion ratio (FCR) during the periods of Day 0-14 and 15-28, the shallowest ileal crypt depth on Day 28, and the lowest relative duodenum weight on Day 28 and 42. The Pre+Pro diets helped the broilers to reach a lower overall FCR than did the Pro alone diets and helped the broilers reach a FCR similar to that of the Anti diets. However, broilers fed diets supplemented with prebiotics and probiotics exhibited the deepest intestinal crypt depth on Day 28. There was no interaction between coccidial vaccination and dietary additive on growth performance or any carcass yield. In conclusion, antimicrobial additives might reduce the intestinal size of broilers; whereas prebiotic and B. subtilis-based probiotic additives might promote the growth of several digestive organs. Prebiotics can be safely used with B. subtilis-probiotics in broiler feed without compromising feed conversion ability.

Abstract
Background The aberrant expression of long noncoding RNAs (lncRNAs) has recently emerged as key molecules in human cancers; however, whether lncRNAs are implicated in the progression of clear cell renal cell carcinoma (ccRCC) remains unclear. Methods Candidate lncRNAs were selected using microarray analysis and quantitative real-time PCR (qRT-PCR) was performed to detect lncRNAs expression in human ccRCC tissues. Overexpression and knocking down experiments in vivo and in vitro were performed to uncover the biological roles of lncRNA-URRCC on ccRCC cell proliferation and invasion. Microarray, chromatin immunoprecipitation, Luciferase reporter assay and western blot were constructed to investigate the molecular mechanisms underlying the functions of lncRNA-URRCC. Results The microarray analysis and qRT-PCR identified a new lncRNA, URRCC, whose expression is upregulated in RCC samples and associated with poor prognosis, leading to promote ccRCC cell proliferation and invasion. Mechanistically, URRCC enhances the expression of EGFL7 via mediating histone H3 acetylation of EGFL7 promoter, activation of P-AKT signaling, and suppressing P-AKT downstream gene, FOXO3. In return, FOXO3 could inhibit the transcription of URRCC via binding to the special region on the promoter of URRCC. Conclusions Our data suggests that targeting this newly identified feed-back loop between LncRNA-URRCC and EGFL7/P-AKT/FOXO3 signaling may enhance the efficacy of existing therapy and potentially imparts a new avenue to develop more potent therapeutic approaches to suppress RCC progression.

Abstract
Doping metal ions in inorganic halide perovskite (CsPbX3, X = Cl, Br, I) nanocrystals (NCs) endows the NCs with unique optical characteristics, and has thus attracted immense attention. However, controllable synthesis of high-quality doped perovskite NCs with tunable morphology still remains challenging. Here, we report a facile, effective and unified strategy for the controllable synthesis of Mn-doped CsPbCl3 quantum dots (QDs) and nanoplatelets (NPLs) via a single-step solvothermal method. The incorporation of Mn2+ into CsPbCl3 NCs introduces new broad photoluminescence (PL) emission from Mn2+ while maintaining the structure of host CsPbCl3 NCs nearly intact. The PL intensity, emission peak position and size of the NCs can be accurately adjusted by altering the experimental parameters such as Mn-to-Pb feed ratio and reaction time. Especially, by changing the amount of ligands, Mn-doped CsPbCl3 QDs, NPLs or their mixtures can be obtained. Both of the Mn-doped QDs and NPLs exhibit a size-dependent quantum confinement effect, which is confirmed by the relationship between the size of NCs and the exciton emission peaks. The solvothermal reaction condition plays an important role for the precise control of the structure, morphology and PL properties of the Mn-doped NCs. The as-prepared Mn-doped CsPbCl3 NPLs with thickness down to ∼2 nm exhibit a PL quantum yield (PLQY) of more than 22%. This work introduces a new strategy for the controllable synthesis of Mn-doped perovskite NCs, which provides ideas for the in-depth study of the dope-and-grow process and can be extended to approaches of doping other metal ions. A facile solvothermal reaction strategy was developed to obtain Mn-doped CsPbCl3 nanocrystals with tunable morphology and optical properties.![]()

Abstract
So far the controllable synthesis of one-dimensional (1D) CsPbI3 nanocrystals still remains a challenge due to the fast reaction kinetics of the iodine system as compared with other halide perovskites. Here we report the direct synthesis of high-quality 1D CsPbI3 nanorods by a facile solvothermal method. The as-prepared CsPbI3 nanorods show high purity and uniform morphology with ultrafine diameters down to ∼5 nm. By simply changing the solvothermal reaction conditions, fine-tuning of the sizes of the CsPbI3 nanorods can be well achieved, which leads to the successful modulation of their photoluminescence (PL) emission. The solvothermal reaction offers relatively low crystal growth rate, which is of great importance for the size control of the CsPbI3 nanocrystals. PL quantum yields (PLQYs) and lifetime results indicate that the obtained nanorods maintain a good surface state over long reaction time. Our work not only provides a reliable means for the synthesis of 1D iodine-related perovskites, but also expands the study of size-related PL properties on perovskites nanocrystals. Ultrafine CsPbI3 nanorods with tunable narrow photoluminescence emission are directly synthesized by solvothermal method.![]()

Abstract
One-dimensional (1D) inorganic perovskite nanowires (NWs) have attracted promising attention for application in the fields of photodetection, lasers and lighting due to their outstanding optoelectronic properties. However the direct synthesis of highly pure all-inorganic perovskite NWs with well-defined morphologies and compositions still remains challenging. Here we report the controllable synthesis of brightly emitting cesium lead halide CsPbX3 (X = Cl, Br) NWs and their assembly into high-performance photodetector nanodevices. High quality CsPbX3 NWs have been directly synthesized via a solvothermal method without using post-synthetic anion-exchange reactions. The NWs are single-crystalline, with uniform diameters of ∼10 nm and lengths of up to tens of microns, showing ultra-high aspect ratios. Both CsPbCl3 and CsPbBr3 NWs show excellent photoluminescence (PL) characteristics with narrow emission spectra and high PL quantum yields (PLQYs). The photodetectors constructed on the CsPbX3 NWs and interdigital electrodes (with interdigitation widths up to 100 μm) exhibit promising photoelectric properties, achieving high switching ratios (5.8 × 103 for CsPbCl3 NW devices and 1.1 × 103 for CsPbBr3 NW devices) and fast response time. The present solvothermal approach is controllable, convenient, and is easily realized for quantifiable preparation, and can further promote the application of the all-inorganic perovskite NWs in the optoelectronic field.

Abstract
The extraordinary high pressure and temperature produced during cavitation is crucial for ultrasonic sonochemistry. However, the cavitation effect is usually confined to a small zone nearby the ultrasonic horn, outside of which ultrasound produces much less effects on chemical reaction. In present work, in order to expand the range of effective zone and intensify the cavitation effect, N2 aeration was introduced to an ultrasonic polymerization process of CuO@PNIPAM in aqueous solution. By increasing the number of bubble nucleus gathered on the CuO surface and lowering the surface tension of the aqueous solution, the cavitation effect is intensified on the CuO surface within the whole reaction vessel, which benefits the covalently bonding between PNIPAM and CuO to a large degree and results in the formation of CuO@PNIPAM hybrid composite with excellent interfacial bonding. It is promising that the hybrid composite can be applied as temperature responsive glucose sensing platform with ON and OFF states due to the wettability change of PNIPAM versus temperature.

Abstract
Background This study aimed to explore hyper-O-linked N-acetylglucosaminylation (O-GlcNAcylation) with an elevation of the expression of O-linked-β-N-acetylglucosamine transferase (OGT) in human bladder cancer. Methods Immunohistochemical staining for OGT and O-GlcNAcylation was performed in 20 paired human bladder cancer and adjacent normal tissues, as well as in human bladder cancer tissue microarrays (N = 169). The expression level of OGT and O-GlcNAcylation in cell lines were detected using the Western blot analysis. The effects of O-GlcNAcylation on the cell proliferation of bladder cancer were detected using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and clone formation assays. Cell apoptosis and cell cycle analysis were detected using flow cytometry. The autophagy of bladder cancer cells was investigated using the Western blot analysis, and GFP–LC3 plasmid was used to detect the autophagic flux. MTT assay was performed to detect the sensitivity of bladder cancer cells to cisplatin after OGT knockdown. Results The expression of OGT and the O-GlcNAcylation were upregulated in bladder cancer tissues and cell lines. O-GlcNAcylation and OGT were observed in nucleus and cytoplasm and found to be higher in muscle-invasive bladder cancer (MIBC) than in non-muscle-invasive bladder cancer (NMIBC). Reducing hyper-O-GlcNAcylation by OGT knockdown inhibited the proliferation of bladder cancer cells in vitro and xenograft tumor growth in vivo, triggered apoptosis, as well as led to cell cycle arrest. It also increased autophagy in bladder cancer cells. This study demonstrated increased autophagy pro-survival, but not pro-death. Reducing hyper-O-GlcNAcylation by OGT knockdown facilitated the chemosensitivity of bladder cancer cells to cis-platinum. Conclusions The data indicated that hyper-O-GlcNAcylation enhanced oncogenic phenotypes and was involved in DNA damage response in bladder cancer.

Abstract
PURPOSE Although microRNAs (miRNAs) were revealed as crucial modulators in tumor metastasis and target therapy, our understanding of their roles in metastatic renal cell carcinoma (mRCC) and Sunitinib treatment was limited. Here we sought to identify human miRNAs that acted as key regulators in renal cancer metastasis and Sunitinib treatment. EXPERIMENTAL DESIGN We focused on 2 published microarray data to select out our anchored miRNA and then explored the roles of miR-452-5p both in vitro and in vivo, which was downregulated after Sunitinib treatment while upregulated in metastasis renal cell carcinoma (RCC) tissues. RESULTS Here, we discovered that treating with Sunitinib, the targeted receptor tyrosine kinase inhibitor (TKI), inhibited renal cancer cell migration and invasion via attenuating the expression of miR-452-5p. The novel identified miR-452-5p was upregulated and associated with poor prognosis in RCC. Preclinical studies using multiple RCC cells and xenografts model illustrated that miR-452-5p could promote RCC cell migration and invasion in vitro and in vivo. Mechanistically, P65 could directly bind to the miR-452-5p promoter and thus transcriptionally induce miR-452-5p expression, which led to post-transcriptionally abrogate SMAD4 expression, thus inhibition of its downstream gene SMAD7. CONCLUSION Our study presented a road map for targeting this newly identified miR-452-5p and its SMAD4/SMAD7 signals pathway, which imparted a new potential therapeutic strategy for mRCC treatment.

Abstract
Effects of antibiotic (bacitracin), anticoccidial (narasin), and alternative (Bacillus subtilis and zinc) feed additives on growth performance, internal organ development, and intestinal morphology of commercial broilers with or without subclinical coccidia challenge were determined. A total of 1,344 1-day-old male Ross × Ross 708 broilers were randomly distributed into 12 treatments (6 diets × 2 challenge treatments, 8 replication pens/treatment) in 96 floor pens. The 6 dietary treatments were as follows: a control diet (corn and soybean-meal basal diet), a probiotic diet (basal diet + Bacillus subtilis), a zinc diet (basal diet + 100 ppm zinc), a probiotic and zinc combined diet, an anticoccidial diet (basal diet + narasin), and a practical diet (basal diet + narasin + bacitracin). On day 21, each chick in the challenge treatment was gavaged with a 10× dose of a commercial vaccine containing live Eimeria oocytes, whereas each chick in the non-challenge treatment was gavaged with equivalent distilled water. The subclinical coccidia challenge increased the relative weights of pancreas and decreased the ileal crypt depth of broilers at 26 d of age, increased feed conversion ratios from day 15 to 28 and 29 to 40, and increased the relative weights of duodenum and bursa on day 54. As compared to other diets, anticoccidial and practical diets increased BW gain and decreased feed conversion ratio from day 15 to 28, and increased the day 40 carcass weights. As compared to control diets, probiotic diets decreased BW gain and increased the mortality from day 15 to 28; however, probiotic diets did not affect the overall growth performance from day 0 to 54 or carcass yield on day 54. Growth measurements during periods of day 29 to 40 and day 41 to 54 were not affected by any feed additive. From this study, a subclinical coccidia challenge enlarged specific internal organs and compromised the feed conversion ability of broilers. Dietary Bacillus subtilis did not affect overall growth rate or carcass yield of broilers under subclinical coccidia challenge.

Abstract
Mesenchymal stem cells (MSCs) are known for their capacity to produce extracellular vesicles (EVs), which are key mediators of information transfer between different cells for tissue repair and regeneration. Schwann cells are the major glial cells of the peripheral nervous system and play a key role in the survival, function, and regeneration of neurons. However, the action of MSC-derived EVs (MSC-EVs) on Schwann cells remains unclear. In the present study, we investigated the effect of rat bone marrow MSC-EVs on RSC96 Schwann cells. EVs derived from Rat bone marrow MSCs were isolated by ultracentrifugation and characterized by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The effects of MSC-EVs on RSC96 cell proliferation, migration, apoptosis, and the protein levels were analyzed using the MTT and Colony-forming assays, the Transwell and wound healing assays, flow cytometry, and western blot, respectively. We found that rat MSCs secreted 80-400 nm heterogeneous small vesicles, which were defined as EVs. Incubation of RSC96 cells with rat MSC-EVs resulted in the uptake of EVs by the cells. MSC-EV treatment significantly inhibited RSC96 cell proliferation and migration, promoted their apoptosis, and activated the ERK pathway, while ERK signal repression using U0126 exhibited the opposite effects. Our data showed that MSC-EVs inhibited proliferation and migration and promoted apoptosis through the activation of the ERK pathway in RSC96 cells. Thus, the effect of BMSC-EVs on RSC96 cells may affect peripheral nerve injury and repair, as mediated by Schwann cells.

Abstract
Schisandra sphenanthera (Austrobaileyales) is a famous traditional Chinese medicine being long-history used, is also one of early-diverging angiosperms and important links to uncover the early evolution of angiosperms. Here the complete mitochondrial genome of S. sphenanthera was obtained for the first time. It is 1,106,521 bp in length with 46.4% GC content. It contains 58 genes, including 41 protein coding genes, three ribosomal RNA genes and 14 transfer RNA genes. Phylogenetic analysis indicated that S. sphenanthera was placed in the basal angiosperm just after Amborella and Nuphar. The mitogenome of S. sphenanthera would provide a reliable genetic and evolutionary resource.

Abstract
As a crucial component of data terminal acquisition devices, flexible strain sensor has shown promising applications in numerous fields, such as healthcare, bodynet, the intelligent traffic system, and the robotic system. For stretchable strain sensor, it remains a huge challenge to realize a fine balance of wide detection range and high sensitivity. Here, an electrically conductive carbon nanotube/thermoplastic polyurethane fiber with a multilayered, hollow, and monolith structure, accompanying high stretchability (up to 476% strain) and low density (about 0.46 g/cm3) is fabricated through a facile coaxial wet-spun assembly strategy. The as-prepared fibers with a designed independent sensitive zone and flexible supporting zone possess an ultralow percolation threshold (0.17 wt %) and a tunable size and structure. This structure endows the fiber with a good integration of adequate flexibility, suitable strength, and high elongation at break for wearable electronics. The fiber, which is then assembled as a strain sensor, realizes the perfect combination of the wide sensing range (>350% strain), high sensitivity (gauge factor (GF) = 166.7 at 350% strain), and excellent working durability (>10 000 cycles). Our sensor could also detect small compressing deformations (0.35% N-1 at 0.025-50 N) by capturing the resistance change of the fiber with superior stability. The highly stretchable, light weight, and multilayered fiber with the designed hollow-monolith structure provides a new route for the preparation of high-performance wearable electronics.

Abstract
OBJECTIVE To explore the correlation between propagated sensation along meridian (PSM) and TCM constitution at different age stages. METHODS According to age, 840 participants were divided into a youth group (326 cases), a middle aged group (243 cases) and an elderly group (271 cases). The TCM constitution of all the participants was evaluated, and the PSM test was performed. The distribution of TCM constitution, the occurring rate and transmission of PSM in each group were observed and compared; the correlation between PSM and the TCM constitution was preliminary investigated by Logistic regression analysis. RESULTS The distribution of nine types of TCM constitution in three groups:the proportion of normal constitution and partial constitution were significantly different (all P<0.05); the occurring rate and transmission of PSM in three groups were not significantly different (all P>0.05); the proportion of occurring rate for nine types of TCM constitutions in the whole population, from high to low, presented special intrinsic quality, neutral quality, yin-deficiency quality, qi-deficiency quality, yang-deficiency quality, damp-heat quality, phlegm-dampness quality, qi-stagnation quality and blood-stasis quality; besides, the proportion of occurring rate for different TCM constitutions in the youth group, middle aged group and elderly group was similar to that of whole population. The Logistic regression analysis results indicated the neutral quality (P=0.025) and special intrinsic quality (P=0.018) were positively while blood-stasis quality (P=0.043) was negatively related with PSM in all subjects; the qi-deficiency quality (P=0.025), phlegm-dampness quality (P=0.019), blood-stasis quality (P=0.012) and qi-stagnation quality (P=0.035) were negatively related with PSM in youth group; the neutral quality (P=0.001) was positively related with PSM inthe middle aged group; the neutral quality (P=0.006) and yin deficiency quality (P=0.004) were positively related with PSM in the elderly group. CONCLUSIONS The occurrence of PSM in different age stages is related with TCM constitution, which could be increased in clinical treatment to improve acupuncture efficacy.

Abstract
Renal cell carcinoma (RCC) is the most common malignant disease of kidney in adults. The proteasome activator REGγ was previously reported to promote the degradation of multiple important regulatory proteins and involved in the progression and development of numerous human cancers. Here, we first reported that REGγ was upregulated in RCC and its upregulation was correlated with a poor prognosis in RCC patients. REGγ depletion obviously suppressed RCC cells proliferation in vitro and in vivo. Notably, casein kinase 1ε (CK1ε) was identified as a novel target of REGγ and knockdown of CK1ε effectively abolished the effect of REGγ depletion on RCC cells growth. Importantly, we also observed that REGγ depletion activated Hippo signaling pathway via stabilizing CK1ε in RCC, indicating the cross-talk between REGγ/CK1ε axis and Hippo pathway during RCC development. In conclusion, our findings suggested that REGγ played a pivotal role in the development of RCC and maybe helpful to identify new therapeutic strategies in the treatment of RCC.

Abstract
BACKGROUND Skin blood flow is believed to link with many diseases, and shows a significant heterogeneity. There are several papers on basal cutaneous microcirculation perfusion in different races, while the data in Chinese is vacant. OBJECTIVE The aim was to establish the database of absolute fundamental supply of skin blood flow in the Chinese Han population. METHODS With a full-field laser perfusion imager (FLPI), the skin blood flow can be quantified. Cutaneous perfusion values were determined in 17 selected skin areas in 406 healthy participants aged between 20 and 80 years (mean 35.05 ± 11.33). Essential parameters such as weight, height were also measured and values of BMI were calculated. The perfusion values were reported in Arbitrary Perfusion Units (APU). RESULTS The highest cutaneous perfusion value fell on eyelid (931.20 ± 242.59 in male and 967.83 ± 225.49 in female), and pretibial had the lowest value (89.09 ± 30.28 in male and 85.08 ± 33.59 in female). The values were higher in men than women on the bank of fingertips, nose, forehead, cheek, neck and earlobe (P < .05). Perfusion values on stretch and flexion side of forearm had negative correlation with age (P = .01 and P = 4.88 × 10-3 , respectively) in male. Abdomen was negatively correlated with BMI in both gender (P = .02, respectively). CONCLUSIONS Skin blood flow values vary with skin regions. There is a tendency to measure higher perfusion values in men than in women. And the values are irrelevant with age or BMI.

Abstract
The chronic inflammatory microenvironment within or surrounding the primary renal cell carcinoma (RCC) site promotes oncogenic transformation as well as contributes to the development of metastasis. G3BP stress granule assembly factor 1 (G3BP1) was found to be involved in the regulation of multiple cellular functions. However, its functions in RCC have not been previously explored. Here, we first showed that the expression of G3BP1 is elevated in human RCC and correlates with RCC progression. In cultured RCC cells, knockdown of G3BP1 results in inhibition of tumor cell proliferation, migration, and invasion, consistently with the alteration of epithelial–mesenchymal transition (EMT) and cell proliferative markers, including Cadherins, Vimentin, Snail, Slug, c-Myc, and cyclin D1. Remarkably, knockdown of G3BP1 dramatically impaired the signaling connection of pro-inflammatory cytokine IL-6 stimulation and downstream STAT3 activation in RCC, thus eventually contributing to the disruption of IL-6-elicited RCC migration and metastasis. In addition, in vivo orthotopic tumor xenografts results confirmed that knockdown of G3BP1 suppressed RCC tumor growth and metastasis in mice. Collectively, our findings support the notion that G3BP1 promotes tumor progression and metastasis through IL-6/G3BP1/STAT3 signaling axis in RCC.

Abstract
In the current study, Al2O3–TiN composites were successfully fabricated with various particle sizes (10, 20, 30, and 50 μm) and concentrations (5, 10, 15, and 20 vol %) via a novel ball milling + Ti reactive sintering process. By applying the reactive sintering, Ti powders will transform into TiN particles, which act as mechanical reinforcements and electrical conductors in the Al2O3 matrix. The ball milling process alters the Ti powder morphology from a low-aspect-ratio sphere into a high-aspect-ratio disc, which reduces the electrical percolation threshold value from 29% to 15% in the current setup. However, such a threshold value is insensitive to the particle size. Meanwhile, the Ti particle size has a significant influence on the material’s mechanical properties. A small particle size results in less porosity and hence higher flexural strength of the composite.

Abstract
Aberrant expression of microRNA (miRNA) emerges as an important role in a wide range of human malignances, and further identification as well as validation of the change of these endogenous non-protein-coding transcripts is warranted. Here, we identify a novel epigenetic regulation of miR-766-3p and investigate its biological function as well as clinical significance in renal cell carcinoma (RCC). Bisulfate analysis elucidates that the promoter of miR-766-3p is highly methylated in RCC tissues compared to non-tumorous tissues. Notably, the downregulation of miR-766-3p is obviously associated with clinical stage and worse prognosis in RCC patients. Upregulated miR-766-3p attenuates cell-cycle progression via targeting SF2 expression and additional SF2/P-AKT/P-ERK signaling pathway. Moreover, high level of SF2, as a novel oncoprotein in RCC, was significantly associated with poor survival in a large cohort of RCC specimens. Taken together, our study presents a road map for the prediction and validation of miR-766-3p/SF2 axis and thus imparts a therapeutic way for further RCC progression.

Abstract
Acoustic levitation in gaseous media provides a tool to process solid and liquid materials without the presence of surfaces such as container walls and hence has been used widely in chemical analysis, high-temperature processing, drop dynamics and bioreactors. To date high-density objects can only be acoustically levitated in simple standing-wave fields. Here we demonstrate the ability of a small number of peripherally placed sources to generate acoustic vortex fields and stably levitate a wide range of liquid and solid objects. The forces exerted by these acoustic vortex fields on a levitated water droplet are observed to cause a controllable deformation of the droplet and/or oscillation along the vortex axis. Orbital angular momentum transfer is also shown to rotate a levitated object rapidly and the rate of rotation can be controlled by the source amplitude. We expect this research can increase the diversity of acoustic levitation and expand the application of acoustic vortices.

Abstract
BACKGROUND This study investigated the protective effects of pharmaceutical CD26/dipeptidylpeptidase-4 (CD26/DPP-4) inhibitor in lung transplantation (LTx). Changes in protein expression associated with the treatment were screened and identified to evaluate the role of kininogen-1 in early-term ischemia/reperfusion (I/R) injury after LTx. MATERIAL AND METHODS Orthotopic single LTx was performed in syngeneic C57BL/6 mice, with a pharmaceutical CD26/DPP-4 inhibitor (vildagliptin, subcutaneous injection, 10 mg/kg, every 12 h) administered to the investigational group. All donors were perfused and preserved with low potassium dextran (LPD). Grafts were harvested at 60 h post-transplantation after 8 h of cold ischemia. Myeloperoxidase activity and wet/dry weight ratio were measured, followed by histopathological examination. Proteins were separated, analyzed, and identified using proteomics and database searches. The target proteins were validated by Western blot. Immunohistochemical studies were performed in the same lung specimen locus. RESULTS Investigational group (IN) versus control group (CON) comparison showed decreased myeloperoxidase enzymatic activity, as well as decreased edema and interstitial-alveolar inflammation. Proteomics results revealed 78 spots with significant differences in abundance between the 2 groups. Fifteen proteins were identified. Kininogen-1 was up-regulated in CON and down-regulated in IN, with contrasting results for the heat shock protein 70. Immunohistochemical results revealed significantly different staining with kininogen-1 in alveolar macrophages and inflammatory cells. CONCLUSIONS Combined vildagliptin and LPD significantly ameliorated I/R injury after LTx. This treatment may change local pulmonary protein levels. Moreover, proper application of proteins such as kininogen-1 may enhance the protective effects against I/R injury during transplantation.

Abstract
AIM To evaluate the effect of TCM music therapy for hospice care of patients with gastrointestinal cancer.
METHODS One hundred and six patients with gastrointestinal cancer treated from April 2013 to January 2016 in the hospice ward of our hospital were randomly divided into either an observation group to receive TCM music therapy or a control group to receive basic therapy. Hamilton Depression Scale (HAMD) score, Karnofsky performance scale (KPS) score, and nursing satisfaction were compared between the two groups.
RESULTS At 2 and 4 wk after treatment, the HAMD scores were significantly increased and the KPS scores were significantly decreased in both groups (P < 0.05), and the improvement was significantly better in the observation group than in the control group (P < 0.05). The rate of nursing satisfaction was significantly higher in the observation group than in the control group (90.57% vs 69.81%).
CONCLUSION Chinese music therapy can significantly improve the hospice care of patients in terms of reducing depression and improving the functional status of patients.

Abstract
When one beam of ultrasound propagates along a single direction in liquids, the cavitation effect is always confined to a limited volume close to the ultrasonic source. This greatly limits the application of power ultrasound in liquid processing and materials fabrication. In this study, a methodology for applying three orthogonal ultrasounds within liquids has been proposed. By solving the Helmholtz equation, the sound field distribution characteristics are investigated in 1D (one dimensional), 2D (two dimensional) and 3D (three dimensional) ultrasounds at their resonant frequencies, which show that the coherent interaction of three beams of ultrasounds is able to strikingly promote the sound pressure level and reinforce the mean acoustic energy density as compared with that in 1D case. Hence, the potential cavitation volume is enlarged remarkably. This opens new possibilities for the design and optimization of ultrasonic technology in fabricating materials.

Abstract
BACKGROUND An increased demand for accountability and transparency in medicine have initiated a shift toward a more objective and standardized approach for postgraduate medical training. OBJECTIVE To develop and evaluate an objective method to assess clinical competence of postgraduate year 1 surgery residents. DESIGN Thirty-one postgraduate year 1 surgery residents, who had been trained in the Surgical School of Peking University First Hospital for one year, participated in an objective structured clinical examination as a final assessment of their clinical competence. A test station of irregular wound repair (debridement and suture) was specially designed to test the residents' surgical integrative competence in a complex-trauma treatment procedure. A modified global rating scale, in combination with wound area measurement, was applied to evaluate residents' surgical performance. The validity of the subjective global rating scale was evaluated by the objective measurement results from the software. RESULTS The global rating scale score had no obvious correlation with the area of the removed tissue and the residual wound area after the suture. There was significant difference in the debridement time and the residual wound area between 0-3 and >3 total stitches. There were significant differences in the area of the removed tissue between 0 and 1-2 grey stitches and 0 and 3-4 grey stitches, and in the residual wound area after suture between 0 and 3-4 grey stitches and 1-2 and 3-4 grey stitches. CONCLUSIONS An irregular wound repair procedure could be an effective method to assess the integrative competence of surgery residents. The training for surgical thinking in the early stage of junior residents needs to be strengthened. The entire measurement process was more complex and time-consuming than expected. The possibility of measurement by simply counting the numbers of the key spots might be explored in the future.

Abstract
BACKGROUND AND AIMS Infections related to pemetrexed have been reported in clinical trials. It is not yet clear whether this drug increases infection risk or not. This meta-analysis assessed the overall incidence and risk of severe infections (≥ grade 3) associated with the use of pemetrexed in non-small-cell lung cancer patients. METHODS The databases of PubMed, Embase, and the Cochrane Library were searched for relevant studies published up to December 2015. Eligible studies included randomized controlled trials (RCTs) of pemetrexed for non-small-cell lung cancer patients that reported grade 3-5 infection and febrile neutropenia. Summary incidence rates, relative risks (RRs) and 95% confidence intervals (CIs) were calculated by using either random-effects or fixed-effects models, according to the heterogeneity of the included studies. RESULTS Seven randomized controlled trials were included, comprising 1848 patients. The incidence of severe infection and febrile neutropenia due to pemetrexed was 5.7% (95% CI: 3.2-8.3%) and 1.3% (95% CI: 0.7-2.0%), respectively. The use of pemetrexed was associated with an increased risk of severe infection (RR 1.61, 95% CI: 1.07-2.44, P = .02) and febrile neutropenia (RR 4.28, 95% CI: 1.08-17.01, P = .04). CONCLUSION The use of pemetrexed was associated with an increased risk of developing severe infections and febrile neutropenia in non-small-cell lung cancer patients. Frequent clinical monitoring and management of infections should be emphasized during pemetrexed treatment. More studies are needed to reveal the mechanism of the increased risk of severe infections.

Abstract
MeCP2 mutations are associated with the Rett syndrome (RTT). Currently, there is an urgent need for new animal models for RTT as the existing MeCP2 knockout mouse models fail to fully mimic the pathogenesis and symptoms of RTT patients. In order to investigate the role of MeCP2 in brain development and RTT pathogenesis, we aimed to set up the MeCP2-null rat model using the CRISPR/Cas9 technology. Firstly we constructed the MeCP2 targeting vector and then microinjected Cas9 mRNA and sgRNA mixtures into fertilized ova of SD rats. The sgRNA was designed to target the exon 2 of MeCP2. Next, knockout rats were confirmed using DNA sequencing and Western blotting. Lastly, phenotypes including growth and behaviors of MeCP2 knockout rats were analyzed. The results indicated that the MeCP2 knockout rats showed body weight loss, anxiety tendency and cognitive deficits. The MeCP2-null rat model established in this study recapitulates the major symptoms of RTT patients and provides an alternative tool for future studies of MeCP2 functions.

Abstract
Accumulating evidence suggested that microRNA (miRNA) plays important regulatory roles in the initiation and development of various cancers. Previous study showed that microRNA-206 (miR-206) is dysregulated in human bladder cancer tissues, however, the biological function and underlying mechanisms of miR-206 in human bladder cancer remain unknown. In the present study, we aimed to investigate the clinical significance of miR-206 and its target gene YRDC in human bladder cancer, and to determine its effects on oncogenic phenotypes of this disease. Our results showed that miR-206 expression was downregulated significantly in bladder cancer tissues and cell lines compared with adjacent normal bladder tissues and human bladder epithelial immortalized SV-HUC-1 cell line, respectively. Overexpression of miR-206 reduced the expression of YRDC and inhibited bladder cancer cell proliferation, colony formation, migration, invasion and induced cell cycle arrest at G0/G1 phase. In addition, knockdown of YRDC exhibited similar effects with miR-206 overexpression in bladder cancer cells and restoration of YRDC partially reversed the effects of miR-206 in bladder cancer cells. These findings indicated that mir-206 might be a novel target for bladder cancer therapy by targeting YRDC.

Abstract
The production of Al based monotectic alloys with uniform microstructure is usually difficult due to the large density difference between the two immiscible liquid phases, which limits the application of such alloys. Here, we apply three orthogonal ultrasounds during the liquid phase separation process of ternary Al71.9Sn20.4Cu7.7 immiscible alloy. A uniform microstructure consisting of fine secondary (Sn) phase dispersed on Al-rich matrix is fabricated in the whole alloy sample with a large size of 30 × 30 × 100 mm. The numerical calculation results indicate that the coupled effect of three ultrasounds promotes the sound pressure level and consequently enlarges the cavitation zone within the alloy melt. The strong shockwaves produced by cavitation prevent the (Sn) droplets from coalescence, and keep them suspended in the parent Al-rich liquid phase. This accounts for the formation of homogeneous composite structures. Thus the introduction of three orthogonal ultrasounds is an effective way to suppress the macrosegregation caused by liquid phase separation and produce bulk immiscible alloys with uniform structures.

Abstract
Here we observe the attenuation motion of spherical rotors levitated by near-field acoustic radiation force and analyze the factors that affect the duration time of free rotation. It is found that the rotating speed of freely rotating rotor decreases exponentially with respect to time. The time constant of exponential attenuation motion depends mainly on the levitation height, the mass of rotor, and the depth of concave ultrasound emitter. Large levitation height, large mass of rotor, and small depth of concave emitter are beneficial to increase the time constant and hence extend the duration time of free rotation.

Abstract
Dihydromyricetin (DMY), an important flavanone found in Ampelopsis grossedentata, possesses antioxidative properties that ameliorate skeletal muscle insulin sensitivity and exert a hepatoprotective effect. However, little is known about the effects of DMY in the context of high-fat diet (HFD)-induced hepatic insulin resistance. Male Sprague-Dawley(SD) rats were fed a HFD(60% fat) supplemented with DMY for 8 weeks. The administration of DMY to the rats with HFD-induced insulin resistance reduces hyperglycemia, plasma levels of insulin, and steatosis in the liver. Furthermore, DMY treatment modulated 24 metabolic pathways, including glucose metabolism, the TCA cycle. DMY significantly enhanced glucose uptake and improved the translocation of glucose transporter 1. The specificity of DMY promoted the phosphorylation of AMP-activated protein kinase (AMPK). In addition, the exposure of HepG2 cells to high glucose concentrations impaired the insulin-stimulated phosphorylation of Akt2 Ser474 and insulin receptor substrate-1 (IRS-1) Ser612, increased GSK-3β phosphorylation, and upregulated G6Pase and PEPCK expression. Collectively, DMY improved glucose-related metabolism while reducing lipid levels in the HFD-fed rats. These data suggest that DMY might be a useful drug for use in type 2 diabetes insulin resistance therapy and for the treatment of hepatic steatosis.

Abstract
Alzheimer's disease (AD), the most common cause of dementia worldwide, is mainly characterized by the aggregated β-amyloid (Aβ) and hyperphosphorylated tau. Safflower yellow (SY) is a novel water extract of natural safflower and has been suggested to ameliorate memory deficits in several animal models of dementia. In this study, we aimed to investigate the effect and mechanism of SY on deficits of learning and memory and hyperphosphorylation of tau in APP/PS1 double transgenic mice. APP/PS1 mice were administered with SY (10, 30, 100 mg/kg) by oral gavage for three months at the age of six months. The ability of learning and memory was investigated using the step-down test and Morris water maze test, and protein level in the brain was evaluated using western blot. Here, we found that SY treatment can improve spatial learning and memory ability, and reduce tau hyperphosphorylation at Ser199, Thr205, Ser396, Ser404 sites in APP/PS1 mice. In addition, the activity the of cyclin-dependent kinase 5 (CDK-5) and glycogen synthase kinase 3β (GSK-3β), major kinases involved in tau phosphorylation, was siginificantly decreased in APP/PS1 mice by SY treatment. These results support SY can serve as a promising multitarget neuronal therapeutic agent for the treatment of AD.

Abstract
Partitioning defective protein 3 (Par3) can activate the Tiam1/Rac pathway to inhibit invasion and metastasis in many cancers; however, the role of Par3 in lung adenocarcinoma remains unknown. Here we show that Par3 is downregulated in lung adenocarcinoma tissues and is associated with higher rates of lymph node metastasis and recurrence. Our functional study demonstrated that knock-down of Par3 promoted lung adenocarcinoma cell growth, cell migration, tumor formation, and metastasis, all of which were effectively inhibited when 14-3-3ζ was silenced. We found that Par3 binded with 14-3-3ζ protein and also showed that Par3 abrogated the binding of 14-3-3ζ to Tiam1, which was responsible for Rac1 activation. Knock-down of 14-3-3ζ inhibited Tiam1/Rac-GTP activation and blocked the invasive behavior of cells lacking Par3. These data suggest that loss of Par3 promotes metastatic behavior in lung adenocarcinoma cells through 14-3-3ζ protein.

Abstract
X-box binding protein 1 (XBP1) was found to be overexpressed in glioma and breast cancers, suggesting that XBP1 might act as a potent oncogenic protein. However, the clinical significance and biological role of XBP1 in esophageal squamous cell carcinoma (ESCC) remain unknown. In this study, we report that XBP1 is markedly overexpressed in ESCC cell lines and clinical samples. XBP1 overexpression was significantly correlated with ESCC tumor stage, lymph node metastasis and poor outcome. A functional study demonstrated that XBP1 promoted cell growth and cell invasion both in vitro and in vivo. Further study found that the XBP1-mediated invasion and proliferation of cancer cells requires the up-regulation of matrix metalloproteinase-9 (MMP-9). Importantly, a significant correlation between XBP1 and MMP-9 levels was observed in ESCC clinical samples. Our findings demonstrate that XBP1 is an oncogene that plays an important role in the development of ESCC by activating MMP-9 expression.
