Abstract
AIMS To examine the influence of GED on the gut microbiota and metabolites using a bilateral ovariectomized (OVX) rat model. We tried to elucidate the underlying mechanisms of GED in the treatment of menopausal hot flashes. METHODS AND RESULTS 16S rRNA sequencing, metabonomics, molecular biological analysis, and fecal microbiota transplantation (FMT) were conducted to elucidate the mechanisms by which GED regulates the gut microbiota. GED significantly reduced OVX-induced hot flashes and improved disturbances in the gut microbiota metabolites. Moreover, FMT validated that the gut microbiota can trigger hot flashes, while GED can alleviate hot flash symptoms by modulating the composition of the gut microbiota. Specifically, GED upregulated the abundance of Blautia, thereby increasing l(+)-ornithine levels for the treatment of menopausal hot flashes. Additionally, GED affected endothelial nitric oxide synthase and heat shock protein 70 (HSP70) levels in the hypothalamic preoptic area by changing the gut microbiota composition. CONCLUSIONS Our study illuminated the underlying mechanisms by which GED attenuated the hot flashes through modulation of the gut microbiota and explored the regulatory role of the gut microbiota on HSP70 expression in the preoptic anterior hypothalamus, thereby establishing a foundation for further exploration of the role of the gut-brain axis in hot flashes.

Abstract
Current studies have indicated that insufficient trophoblast epithelial-mesenchymal transition (EMT), migration and invasion are crucial for spontaneous abortion (SA) occurrence and development. Exosomal miRNAs play significant roles in embryonic development and cellular communication. Hereon, we explored the roles of serum exosomes derived from SA patients on trophoblast EMT, migration and invasion. Exosomes were isolated from normal control (NC) patients with abortion for unplanned pregnancy and SA patients, then characterized by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and western blotting. Exosomal miRNA profiles were identified by miRNA sequencing. The effects of serum exosomes on trophoblast migration and invasion were detected by scratch wound healing and transwell assays, and other potential mechanisms were revealed by quantitative real-time PCR (RT-PCR), western blotting and dual-luciferase reporter assay. Finally, animal experiments were used to explore the effects of exosomal miR-410-3p on embryo absorption in mice. The serum exosomes from SA patients inhibited trophoblast EMT and reduced their migration and invasion ability in vitro. The miRNA sequencing showed that miR-410-3p was upregulated in SA serum exosomes. The functional experiments showed that SA serum exosomes restrained trophoblast EMT, migration and invasion by releasing miR-410-3p. Mechanistically, SA serum exosomal miR-410-3p inhibited trophoblast cell EMT, migration and invasion by targeting TNF receptor-associated factor 6 (TRAF6) at the post-transcriptional level. Besides, SA serum exosomal miR-410-3p inhibited the p38 MAPK signalling pathway by targeting TRAF6 in trophoblasts. Moreover, milk exosomes loaded with miR-410-3p mimic reached the maternal-fetal interface and aggravated embryo absorption in female mice. Clinically, miR-410-3p and TRAF6 expression were abnormal and negatively correlated in the placental villi of SA patients. Our findings indicated that exosome-derived miR-410-3p plays an important role between SA serum and trophoblasts in intercellular communication, suggesting a novel mechanism by which serum exosomal miRNA regulates trophoblasts in SA patients.

Abstract
Abstract
Background
Gut microbes were closely related to women’s health. Previous studies reported that the gut microbes of premenopausal women were different from those of postmenopausal women. However, little was known about the relationship between gut microbiota dysbiosis and menopausal syndrome (MPS). The aim of this study was to explore the relationship between MPS and gut microbes.
Methods
Patients with MPS (P group, n = 77) and healthy women (H group, n = 24) at menopause were recruited in this study. The stool specimen and clinical parameters (demographic data, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), et al) of participants’ were collected. We evaluated the differences in gut microbes by 16S ribosomal RNA gene sequencing. We used LEfSe to identify gut microbes with varying abundances in different groups. The Spearman correlation coefficients of clinical parameters and gut microbes were calculated. PICRUSt was used to predict the potential KEGG Ortholog functional profiles of microbial communities.
Results
The abundance of 14 species differed substantially between the MPS and menopausal healthy women (LDA significance threshold > 2.0) according to LEfSe analysis. Using Spearman’s correlation analysis, it was discovered that E2 had a positive correlation with Aggregatibacter segnis, Bifidobacterium animalis, Acinetobacter guillouiae (p < 0.05, these three species were enriched in menopausal healthy women), while FSH and LH had a negative correlation with them (p < 0.05). KEGG level3 metabolic pathways relevant to cardiovascular disease and carbohydrate metabolism were enriched in the MPS (p < 0.05), according to functional prediction by PICRUST and analyzed by Dunn test.
Conclusion
There was gut microbiota dysbiosis in MPS, which is reflected in the deficiency of the abundance of Aggregatibacter segnis, Bifidobacterium animalis and Acinetobacter guillouiae related to the level of sex hormones. In MPS individuals, species with altered abundances and unique functional pathways were found.

Abstract
Ulcerative colitis-colorectal cancer (UC-CRC) is one of the most serious complications in patients with ulcerative colitis (UC), with worse prognosis and higher mortality than sporadic colorectal cancer (CRC). Since most UC-CRC developed through the "inflammation-dysplasia-carcinoma" approach, early detection of dysplasia through identification of high-risk groups reasonable monitoring and active prevention are extremely important. However, there is no consensus on the risk factors of UC carcinogenesis and the drugs that can be used for chemoprevention currently. This article combined with relevant literature at home and abroad, reviewed the current risk factors and chemopreventive drugs for UC carcinogenesis, in order to provide reference for early prevention, early detection and early diagnosis of UC-CRC.

Abstract
We review the relationship between miRNAs associated with ferroptosis and the evolution of AS. Even though, more evidence is asked to determine the role of miRNAs associated with ferroptosis in the AS, this review will help us understand the role of miRNAs in ferroptosis and AS and may provide new insights for probing new biomarkers for the diagnosis and treatment of AS for the time to come. This is a narrative essay. Using PubMed as the main source, a literature search strategy was randomly implemented to index Scopus articles. No specific terminology is used. Studies have shown that ferroptosis plays a crucial role in the development of AS, and a large amount of ferroptosis in cells can lead to the progression of AS. MicroRNAs (MiRNAs) have been proved to be taken part in the biological course of ferroptosis and thus the process of AS is affected. The exact regulatory mechanism behind this appearance remains unclear. In order to clarify this, a growing number of studies have concentrated the regulatory role of miRNAs in the process of generation and development of ferroptosis, as well as the function of ferroptosis in the progression of AS. MiRNAs play a significant role in the process of ferroptosis and are incredibly significant in the occurrence, development, clinical diagnosis, treatment and prognosis evaluation of AS.

Abstract
Ovarian cancer (OV) is a complex gynecological disease, and its molecular characteristics are not clear. In this study, the molecular characteristics of OV subtypes based on metabolic genes were explored through the comprehensive analysis of genomic data. A set of transcriptome data of 2752 known metabolic genes was used as a seed for performing non negative matrix factorization (NMF) clustering. Three subtypes of OV (C1, C2 and C3) were found in analysis. The proportion of various immune cells in C1 was higher than that in C2 and C3 subtypes. The expression level of immune checkpoint genes TNFRSF9 in C1 was higher than that of other subtypes. The activation scores of cell cycle, RTK-RAS, Wnt and angiogenesis pathway and ESTIMATE immune scores in C1 group were higher than those in C2 and C3 groups. In the validation set, grade was significantly correlated with OV subtype C1. Functional analysis showed that the extracellular matrix related items in C1 subtype were significantly different from other subtypes. Drug sensitivity analysis showed that C2 subtype was more sensitive to immunotherapy. Survival analysis of differential genes showed that the expression of PXDN and CXCL11 was significantly correlated with survival. The results of tissue microarray immunohistochemistry showed that the expression of PXDN was significantly correlated with tumor size and pathological grade. Based on the genomics of metabolic genes, a new OV typing method was developed, which improved our understanding of the molecular characteristics of human OV.

Abstract
Objective: To analyze the effect of psychological suggestion combined with rational food restriction therapy on blood glucose, lipid metabolism and mental resilience in patients with diabetes. Methods: Patients with diabetes admitted to the Third Hospital of Nanchang from January 2020 to August 2020 were divided into the control group and the intervention group with randomized controlled and single blind methods. The control group was treated with routine dietary guidance and health education, and the intervention group was treated with psychological suggestion combined with rational diet therapy on the basis of the control group. Both groups were treated for 3 months. Blood glucose, lipid metabolism, mental resilience and quality of life were compared between the two groups at baseline and after 3-month intervention. Differences between groups and within groups were analyzed by t test and χ2 test. Results: 100 patients in the control group and 81 patients in the intervention group completed 3-month intervention. After 3-month intervention, the levels of glycosylated hemoglobin, fasting blood glucose, 2-hour postprandial blood glucose, low-density lipoprotein cholesterol and triglyceride in both groups were lower than those before intervention. The levels of these indicators in intervention group were lower than those in control group (P<0.05). However, the levels of high-density lipoprotein cholesterol and the scores of tenacity, self-reliance, optimism, role function, emotional function, social function, physical function and cognitive function in both groups were higher than those before intervention. These indicators in intervention group were higher than those in control group (P<0.05). Conclusion: Psychological suggestion combined with rational food restriction therapy could effectively improve the glucose and lipid metabolism, mental resilience, and quality of life among patients with diabetes.

Abstract
Bifunctional electrocatalysts play a key role in the performance of rechargeable metal-air batteries. Herein, we report a hybrid catalyst, Ag1.8 Mn8 O16 /rGO, self-assembled by Ag1.8 Mn8 O16 nanorods and reduced graphene oxide (rGO) nanosheets through electrostatic attraction. The hybrid catalyst exhibits a better oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) activity than commercial Pt/C in alkaline medium. When employed as an air-cathode catalyst in Zn-air cells, the hybrids enabled higher and more stable output voltage and better durability of the cells, benefitting from the improved electrode conductivity, larger surface area, and synergetic coupling as a result of its high structural integrity.

Abstract
Abstract
Study question
What are the other male factors that cause total fertilization failure (TFF) excepting for variants in PLCZ1?
Summary answer
Homozygous variants in ACTL9 (actin like 9) cause abnormal localization of PLCζ in a loosened perinuclear theca (PT) structure and leads to TFF.
What is known already
In previous studies, investigators have reported that the female factors in TFF after intracytoplasmic sperm injection (ICSI) include pathogenic variants in WEE2, TLE6, and TUBB8, whereas for male factors, pathogenic variants in PLCZ1 were reported to be the primary cause of TFF, which account for approximately 30% of couples with male factors in TFF excluding globozoospermia. Most recently, it was reported that pathogenic variants in ACTL7A led to reduced expression and abnormal localization of PLCζ, thereby identifying this genetic variant as a potential cause of TFF.
Study design, size, duration
Fifty-four infertile couples with TFF or poor fertilization (fertilization rate of < 20%) at the Reproductive and Genetic Hospital of CITIC-Xiangya during January 2014 to June 2020 were recruited into this study.
Participants/materials, setting, methods
Male factors were identified in (MOAT). WES analysis was used to analyze the genetic factors of individuals with male factors. Sperm morphological study was conducted by H&E staining and TEM. Immunostaining of PLCζ was used to analyze the status of sperm-borne activation factor. A knock-in mouse model was generated by CRISPER-Cas9 technology. Sperm from homozygous Actl9 variant mice were analyzed by TEM and ICSI. ICSI with AOA was performed in couples with ACTL9 variants.
Main results and the role of chance
A total of 54 couples with TFF or poor fertilization were screened, with 21 couples determined to have a male infertility factor by MOAT. Whole-exome sequencing of these 21 male individuals identified three homozygous pathogenic variants in ACTL9 in three individuals. ACTL9 variations led to abnormal ultrastructure of the PT, with PLCζ absent in the head and present in the neck of the mutant sperm, which contributed to failed normal calcium oscillations in oocytes and subsequent TFF. The key roles of ACTL9 in the PT structure and TFF after ICSI were further confirmed in Actl9-mutated mouse model. Furthermore, assisted oocyte activation by calcium ionophore exposure successfully overcame TFF and achieved live births in a couple with an ACTL9 variant.
Limitations, reasons for caution
The mechanism of how ACTL9 regulate PLCζ remains unknown.
Wider implications of the findings: It provided a genetic marker and a therapeutic option for individuals who have undergone ICSI without successful fertilization.

Abstract
Objective: Lung adenocarcinoma (LADC) is classified into five main histological subtypes with distinct clinicopathologic characteristics: lepidic-predominant adenocarcinoma (LPA), acinar-predominant adenocarcinoma (APA), papillary-predominant adenocarcinoma (PPA), micropapillary-predominant adenocarcinoma (MPA) and solid-predominant adenocarcinoma (SPA). However, the mutational profiles of predominant histological subtypes have not been well defined. In this study, we aimed to reveal the genomic landscape of 5 main histological subtypes. Patients and Methods: We performed next-generation sequencing (NGS) in a cohort of 86 stage I invasive adenocarcinoma (IAC) patients, using a customized panel including 168 cancer-associated genes. Results: Our analysis identified a total of 302 genomic alterations. Five subtypes showed different mutation profiles with LPA, APA, PPA, MPA and SPA had an average mutation rate of 1.95 (range: 0-5), 2.56 (range: 1-6), 3.5 (range: 1-7), 3.75 (range: 1-8) and 6.05 (range: 2-12), respectively (p=4.17e-06). Driver mutations occurred in 96.55% (83/86) of all patients. EGFR (73.3%), KRAS (9.3%), ALK (4.7%) and MET (4.7%) are the most commonly mutated lung cancer driver genes, TP53 is the top mutated tumor suppressor gene. SPA patients harbored more driver mutations and higher frequency of TP53 than LPA patients. Interestingly, LRP1B mutations, which has been reported to be associated with high tumor mutation burden and better response to immunotherapy, were only detected from 5 SPA patients (p=0.001). No patients from other four cohorts harbored LRP1B mutations. Conclusions: We revealed distinctive mutation landscape of the 5 major histological subtypes of LADC, evident by distinctive average mutation rate with SPA and LPA having the highest and lowest average mutation rate, respectively. SPA patients showed higher mutation rate of LRP1B and higher rates for PD-L1 positivity, indicating that SPA patients may have better response to immunotherapy.

Abstract
Four types of ultra-low carbon bainite (ULCB) steels were obtained using unified production methods to investigate solely the effect of niobium content on the performance of ULCB steels. Tensile testing, low-temperature impact toughness testing, corrosion weight-loss method, polarization curves, electrochemical impedance spectroscopy (EIS), and the corresponding organizational observations were realized. The results indicate that the microstructure of the four steels comprise granular bainite and quite a few martensite/austenite (M/A) elements. The niobium content affects bainite morphology and the size, quantity, and distribution of M/A elements. The elongation, yield strength, and tensile strength of the four types of ULCB steels are above 20%, 500 MPa, and 650 MPa, respectively. The impact toughness of the four types of ULCB steels at -40 °C is lower than 10 J. Steel with Nb content of 0.0692% has better comprehensive property, and maximum charge transfer resistance in 3.5 wt.% NaCl solution at the initial corrosion stage. The corrosion products on the surface of steel with higher niobium content are much smoother and denser than those steel with lower niobium content after 240 h of corrosion. The degree of corrosion decreases gradually with the increase of niobium content at the later stage of corrosion.

Abstract
e21067 Background: Lung adenocarcinoma (LADC) is classified into 5 main histological subtypes with distinct clinicopathologic characteristics: lepidic-predominant adenocarcinoma (LPA), acinar-predominant adenocarcinoma (APA), papillary-predominant adenocarcinoma (PPA), micropapillary component (MPC) and solid-predominant adenocarcinoma (SPA). However, the mutational profiles of predominant histological subtypes have not been well defined. In this study, we aimed to reveal the genomic landscape of the 5 main histological subtypes. Methods: Surgically resected tumor samples were obtained from 86 patients with pathological stage I invasive lung adenocarcinoma who underwent surgery between January 2015 and December 2018. No patient had received preoperative chemotherapy or radiotherapy. Capture-based targeted sequencing was performed in a cohort of 86 stage I invasive adenocarcinoma (IAC) patients spanning 5 subtypes using a panel consisting of 168 lung cancer-related genes. Results: Our analysis identified a total of 302 genomic alterations. Five subtypes showed distinct mutation profiles with LPA, APA, PPA, MPC and SPA had an average mutation rate of 1.95 (range: 0–5), 2.56 (range: 1–6), 3.5 (range: 1–7), 3.75 (range: 1-8) and 6.05 (range: 2-12), respectively (p = 4.17e-06). In this cohort, 96.55% (83/86) of all patients had mutations in classic lung cancer drivers with EGFR (73.3%), KRAS (9.3%), ALK (4.7%) and MET (4.7%) being the most commonly mutated drivers. TP53 is the top mutated tumor suppressor gene. It has been reported that SPA and MPC have unfavorable prognosis comparing to the rest subtypes. Interestingly, LRP1B mutations, which has been reported to be associated with high tumor mutation burden and better response to immunotherapy, were only detected from 5 SPA patients (p = 0.001). No MPC patients from this cohort harbored LRP1B mutations. Conclusions: We revealed distinctive mutation landscape of the 5 major histological subtypes of LADC, evident by distinctive average mutation rate with SPA and PLA having the highest and lowest average mutation rate, respectively. Furthermore, we also showed that SPA patients harboring LRP1B mutations may benefit from immunotherapy.

Abstract
Compatible energy storage devices that are able to withstand various mechanical deformations, while delivering their intended functions, are required in wearable technologies. This imposes constraints on the structural designs, materials selection, and miniaturization of the cells. To date, extensive efforts have been dedicated towards developing electrochemical energy storage devices for wearables, with a focus on incorporation of shape-conformable materials into mechanically robust designs that can be worn on the human body. In this review, we highlight the quantified performances of reported wearable electrochemical energy storage devices, as well as their micro-sized counterparts under specific mechanical deformations, which can be used as the benchmark for future studies in this field. A general introduction to the wearable technology, the development of the selection and synthesis of active materials, cell design approaches and device fabrications are discussed. It is followed by challenges and outlook toward the practical use of electrochemical energy storage devices for wearable applications.

Abstract
A high-performance composite bifunctional electrocatalyst for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) has been synthesized via in situ growth of a hybrid precursor of graphene oxide (GO) and cobalt-based zeolite imidazolium framework (ZIF-67) under hydrothermal condition, followed by calcination at elevated temperature. The as-prepared composite bifunctional catalyst is confirmed to possess a structure of N-GC/Co@CoO/rGO, with core–shell nanoparticles of Co@CoO encapsulated in nitrogen-doped graphitic carbon (N-GC) thin layers which are then overall supported by reduced graphene oxide (rGO) sheets. With N-GC furnishing high population of ORR active sites, CoO being active for OER which is further enhanced by a highly conductive metal core, rGO sheets enhancing the overall electronic conduction, as well as the multiple synergistic couplings in the composite materials, pronounced ORR and OER catalytic activities with superior stability have been achieved. The catalysts also showed excellent tolerance to the crossover effect to methanol, showing great potential in energy-related applications requiring efficient oxygen electrocatalysis. An efficient bifunctional electrocatalyst with sandwich structure, i.e., highly nitrogen-doped graphitic carbon (N-GC/Co@CoO, carbonized from ZIF-67) on reduced graphene oxide (rGO), has been obtained through hydrothermal and carbonization treatment.![]()

Abstract
Similar to heterostructures composed of different materials, possessing unique properties due to the synergistic effect between different components, the crystal-phase heterostructures, one variety of hetero-phase structures, composed of different crystal phases in monometallic nanomaterials are herein developed, in order to explore crystal-phase-based applications. As novel hetero-phase structures, amorphous/crystalline heterostructures are highly desired, since they often exhibit unique properties, and hold promise in various applications, but these structures have rarely been studied in noble metals. Herein, via a one-pot wet-chemical method, a series of amorphous/crystalline hetero-phase Pd nanosheets is synthesized with different crystallinities for the catalytic 4-nitrostyrene hydrogenation. The chemoselectivity and activity can be fine-tuned by controlling the crystallinity of the as-synthesized Pd nanosheets. This work might pave the way to preparing various hetero-phase nanostructures for promising applications.

Abstract
Hierarchical metal nanostructures containing 1D nanobuilding blocks have stimulated great interest due to their abundant active sites for catalysis. Herein, hierarchical 4H/face-centered cubic (fcc) Ru nanotubes (NTs) are synthesized by a hard template-mediated method, in which 4H/fcc Au nanowires (NWs) serve as sacrificial templates which are then etched by copper ions (Cu2+ ) in dimethylformamide. The obtained hierarchical 4H/fcc Ru NTs contain ultrathin Ru shells (5-9 atomic layers) and tiny Ru nanorods with length of 4.2 ± 1.1 nm and diameter of 2.2 ± 0.5 nm vertically decorated on the surface of Ru shells. As an electrocatalyst for the hydrogen evolution reaction in alkaline media, the hierarchical 4H/fcc Ru NTs exhibit excellent electrocatalytic performance, which is better than 4H/fcc Au-Ru NWs, commercial Pt/C, Ru/C, and most of the reported electrocatalysts.

Abstract
The rational design and synthesis of anisotropic 3D nanostructures with specific composition, morphology, surface structure, and crystal phase is of significant importance for their diverse applications. Here, the synthesis of well-crystalline lotus-thalamus-shaped Pt-Ni anisotropic superstructures (ASs) via a facile one-pot solvothermal method is reported. The Pt-Ni ASs with Pt-rich surface are composed of one Ni-rich "core" with face-centered cubic (fcc) phase, Ni-rich "arms" with hexagonal close-packed phase protruding from the core, and facet-selectively grown Pt-rich "lotus seeds" with fcc phase on the end surfaces of the "arms." Impressively, these unique Pt-Ni ASs exhibit superior electrocatalytic activity and stability toward the hydrogen evolution reaction under alkaline conditions compared to commercial Pt/C and previously reported electrocatalysts. The obtained overpotential is as low as 27.7 mV at current density of 10 mA cm-2 , and the turnover frequency reaches 18.63 H2 s-1 at the overpotential of 50 mV. This work provides a new strategy for the synthesis of highly anisotropic superstructures with a spatial heterogeneity to boost their promising application in catalytic reactions.

Abstract
Catalysts for hydrogen evolution reaction are in demand to realize the efficient conversion of hydrogen via water electrolysis. In this work, cobalt phosphides were prepared using a one-step, scalable, and direct gas-solid phosphidation of commercially available cobalt salts. It was found that the effectiveness of the phosphidation reaction was closely related to the state of cobalt precursors at the reaction temperature. For instance, a high yield of cobalt phosphides obtained from the phosphidation of cobalt(II) acetate was related to the good stability of cobalt salt at the phosphidation temperature. On the other hand, easily oxidizable salts (e.g., cobalt(II) acetylacetonate) tended to produce a low amount of cobalt phosphides and a large content of metallic cobalt. The as-synthesized cobalt phosphides were in nanostructures with large catalytic surface areas. The catalyst prepared from phosphidation of cobalt(II) acetate exhibited an improved catalytic activity as compared to its counterpart derived from phosphidation of cobalt(II) acetylacetonate, showing an overpotential of 160 and 175 mV in acidic and alkaline electrolytes, respectively. Both catalysts also displayed an enhanced long-term stability, especially in the alkaline electrolyte. This study illustrates the direct phosphidation behavior of cobalt salts, which serve as a good vantage point in realizing the large-scale synthesis of transition-metal phosphides for high-performance electrocatalysts.

Abstract
The construction of two-dimensional (2D) ultrathin nanosheets is considered as a promising strategy for enhancing electrochemical performance, owing to their large surface area and fast electron transport. In this study, ultrathin few-layer NiPS3 nanosheets are obtained and systematically investigated by high-yield liquid phase exfoliation from their bulk layered crystals, and are exploited as anodes for lithium ion batteries (LIBs) and electrocatalysts for oxygen evolution reaction (OER). When evaluated as an anode for LIBs, NiPS3 nanosheets show excellent electrochemical properties in terms of stable cycling performance and rate capabilities. A stable reversible capacity of 796.2 mA h g-1 is delivered after the 150th cycle at a current density of 100 mA g-1. As for the OER, the exfoliated few-layer NiPS3 nanosheets have demonstrated excellent electrocatalytic performance, such as a low overpotential of 301 mV at a current density of 10 mA cm-2, a small Tafel slope of 43 mV dec-1, and an outstanding long-term durability. This work is expected to make a contribution to develop next generation high-performance electrochemically active materials for catalysts and batteries.

Abstract
Abstract
Background:
We and others demonstrated that truncated p110 ERBB2 (p110 t-ERBB2, also as 611CTF) is a hyperactive truncated ERBB2 isoform capable of increasing cell migration and invasion in multiple cell types in vitro, and induction of human breast epithelial cell (HMLE) xenograft formation in vivo [Ward, et al., Oncogene (2013) 32, 2463–2474]. p110 t-ERBB2 arises through alternative initiation of translation from methionine 611, however, it is unclear how regulation of its expression may be achieved. mRNA structural elements termed internal ribosome entry sites (IRESs) can initiate translation in a cap-independent manner when canonical cap-dependent translation is severely compromised. By cloning the EGFR 5' untranslated region (UTR) between the Renilla and firefly luciferase open reading frames of pRF, Webb, et al. have reported human EGFR 5' UTR sequence can initiate expression of a downstream open reading frame via an IRES [Oncogenesis (2014) 3, e134]. Therefore, we sought to identify presence of a putative IRES within the 5'UTR ERBB2 mRNA which might mediate alternative ERBB2 protein translation initiation under stress conditions and promote p110 t-ERBB2 biosynthesis.
Methods:
Discistronic reporter pRF was used as the backbone vector to detect IRES activity. Promoter-less vector pRFΔP were constructed by removing SV40 promoter via restriction digestion. The HER2 mRNA 5'UTR (from both variant 1 and variant 3) and several overlapping sequences from full length ERBB2 (p185 ERBB2) start codon to p110 t-ERBB2 start codon were cloned between the Renilla and firefly luciferase open reading frames of pRF and pRFΔP, then the resultant constructswere transiently transfected into different cell lines(BT474, SK-BR3, MCF-7, HeLa, CHO). Three control constructs pRF (empty vector control), pRF-Tub (negative control, containing βtubulin 5'UTR, which lacks IRES activity) and pRF-myc (positive control, containing the well-characterized c-myc IRES) were parallel-transfected. Luciferase expression was then quantified using a Dual Luciferase Assay Kit (Promega, Madison, WI, USA) following manufacturer's instructions. Parallel western blot analysis and qRT-PCR were also conducted.
Results:
In this report, we demonstrate that in BT474 and SK-BR3 cells, no IRES activity was detected within human ERBB2 5'UTR sequences under non-stressed conditions, or under serum-starvation, hypoxic conditions or thapsgargin-induced endoplasmic reticulum stress -- conditions when global translation was compromised.The construct pRF-+265/+1561 (within ERBB2 mRNA coding sequence, 5' to the p110 t-ERBB2 start codon) displayed a 10-21 fold increase in firefly/Renilla activity when compared with the empty control pRF and negative control pRF-Tub,consistent with the possibility that the region between +265/+1561 may contain a cryptic promoter.
Conclusions:
These data are inconsistent with the hypothesis that a 5'UTR IRES-mediated mechanism is involved in the translation of p110 t-ERBB2 isoform, and that other mechanisms are operative in alternative translational regulation/biosynthesis of p110 ERBB2 isoform.

Abstract
Herein, the hydrothermal synthesis of porous ultrathin ternary NiFeV layer double hydroxides (LDHs) nanosheets grown on Nickel foam (NF) substrate as a highly efficient electrode toward overall water splitting in alkaline media is reported. The lateral size of the nanosheets is about a few hundreds of nanometers with the thickness of ≈10 nm. Among all molar ratios investigated, the Ni0.75 Fe0.125 V0.125 -LDHs/NF electrode depicts the optimized performance. It displays an excellent catalytic activity with a modest overpotential of 231 mV for the oxygen evolution reaction (OER) and 125 mV for the hydrogen evolution reaction (HER) in 1.0 m KOH electrolyte. Its exceptional activity is further shown in its small Tafel slope of 39.4 and 62.0 mV dec-1 for OER and HER, respectively. More importantly, remarkable durability and stability are also observed. When used for overall water splitting, the Ni0.75 Fe0.125 V0.125 -LDHs/NF electrodes require a voltage of only 1.591 V to reach 10 mA cm-2 in alkaline solution. These outstanding performances are mainly attributed to the synergistic effect of the ternary metal system that boosts the intrinsic catalytic activity and active surface area. This work explores a promising way to achieve the optimal inexpensive Ni-based hydroxide electrocatalyst for overall water splitting.

Abstract
The rational design and synthesis of nonprecious, efficient, and stable electrocatalysts to replace precious noble metals are crucial to the future of hydrogen economy. Herein, a partial sulfurization/phosphorization strategy is proposed to synthesize a nonstoichiometric pyrrhotite-type cobalt monophosphosulfide material (Co0.9S0.58P0.42) with a hexagonal close-packed phase for electrocatalytic water splitting. By regulating the degree of sulfurization, the P/S atomic ratio in the cobalt monophosphosulfide can be tuned to activate the Co3+/Co2+ couples. The synergy between the nonstoichiometric nature and the tunable P/S ratio results in the strengthened Co3+/Co2+ couples and tunable electronic structure and thus efficiently promotes the oxygen/hydrogen evolution reaction (OER/HER) processes toward overall water splitting. Especially for OER, the Co0.9S0.58P0.42 material, featured with a uniform yolk-shell spherical morphology, shows a low overpotential of 266 mV at 10 mA cm-2 (η10) with a low Tafel slope of 48 mV dec-1 as well as high stability, which is comparable to that of the reported promising OER electrocatalysts. Coupled with the high HER activity of Co0.9S0.58P0.42, the overall water splitting is demonstrated with a low η10 at 1.59 V and good stability. This study shows that phase engineering and composition control can be the elegant strategy to realize the Co3+/Co2+ couple activation and electronic structure tuning to promote the electrocatalytic process. The proposed strategy and approaches allow the rational design and synthesis of transition metal monophosphosulfides toward advanced electrochemical applications.

Abstract
2D Sulfur-doped TiSe2 /Fe3 O4 (named as S-TiSe2 /Fe3 O4 ) heterostructures are synthesized successfully based on a facile oil phase process. The Fe3 O4 nanoparticles, with an average size of 8 nm, grow uniformly on the surface of S-doped TiSe2 (named as S-TiSe2 ) nanoplates (300 nm in diameter and 15 nm in thickness). These heterostructures combine the advantages of both S-TiSe2 with good electrical conductivity and Fe3 O4 with high theoretical Li storage capacity. As demonstrated potential applications for energy storage, the S-TiSe2 /Fe3 O4 heterostructures possess high reversible capacities (707.4 mAh g-1 at 0.1 A g-1 during the 100th cycle), excellent cycling stability (432.3 mAh g-1 after 200 cycles at 5 A g-1 ), and good rate capability (e.g., 301.7 mAh g-1 at 20 A g-1 ) in lithium-ion batteries. As for sodium-ion batteries, the S-TiSe2 /Fe3 O4 heterostructures also maintain reversible capacities of 402.3 mAh g-1 at 0.1 A g-1 after 100 cycles, and a high rate capacity of 203.3 mAh g-1 at 4 A g-1 .

Abstract
Transition metal (M = Fe, Co, Ni) and Se codoped two-dimensional uniform NbS2 (MxNb1-xS2-ySey) nanosheets were synthesized via a facile oil-phase synthetic process. The morphology of MxNb1-xS2-ySey can be adjusted by tuning the amount of metal and Se introduced into NbS2. Among them, the optimized Fe0.3Nb0.7S1.6Se0.4 nanosheets, with lateral sizes of 1-2 μm and approximately 5 nm thick, achieve the best Li-ion and Na-ion storage properties. For example, the Fe0.3Nb0.7S1.6Se0.4 nanosheets depict excellent rate capabilities with fifth-cycle specific capacities of 461.3 mAh g-1 at 10 A g-1 for Li storage and 136 mAh g-1 at 5 A g-1 for Na storage. More significantly, ultralong cyclic stabilities were achieved with reversible specific capacities of 444 mAh g-1 at 5 A g-1 during the 3000th cycle for Li storage and 250 mAh g-1 at 1 A g-1 during the 750th cycle for Na storage. Post-treatment high-resolution transmission electron microscopy was studied to prove that the reversible Li-ion storage in NbS2 was based on a conversion reaction mechanism.

Abstract
Tin disulfide (SnS2) has emerged as a promising anode material for lithium/sodium ion batteries (LIBs/SIBs) due to its unique layered structure, outstanding electrochemical properties and low cost. However, its poor cycling life and time-consuming synthesis as well as low-yield production hinder the practical utilization of nanostructured SnS2. In this work, we demonstrate a simple and reliable dissolution-regeneration strategy to construct a flexible SnS2/sulfur-doped reduced graphene oxide (S-rGO) composite as anodes for LIBs and SIBs, highlighting its mass-production feature. In addition, the robust affinity between SnS2 and S-rGO without interstitial volume is very beneficial for preventing the SnS2 particles from breaking themselves away from the rGO nanosheets into free nanoparticles. As a result, the SnS2/S-rGO composite as anodes delivers high reversible capacities of 1078 mA h g-1 and 564 mA h g-1 (at 0.1 A g-1) for LIBs and SIBs, respectively, and excellent rate capabilities and cycling stability (e.g. 532 mA h g-1 during the 600 cycles at 5.0 A g-1 for LIBs). Our proposed strategy may also possess great potential for the practical application of other electrochemically active metal sulfide composites for energy devices.

Abstract
Objective: To investigate the distribution patterns of 21-gene assay and its influencing factors in Chinese patients with early breast cancer. Methods: Nine hundred and twenty-seven early breast cancer patients were retrospectively recruited from January 2009 to December 2015 at Ruijin Hospital, Shanghai Jiaotong University School of Medicine. The 21-gene reverse transcriptase-polymerase chain reaction(RT-PCR) assay were conducted in paraffin-embedded tumor tissues to calculate the Recurrence Score(RS). Immunohistochemistry(IHC) assay was used to measure the expression levels of estrogen receptor(ER), progesterone receptor(PR) and Ki-67. Concordances of RT-PCR and IHC results were assessed. Correlations of RS and classical clinicopathological factors were evaluated, and logistic regression were applied to determine independent predictive factors for RS. Results: The median RS of 927 patients was 23(range: 0~90), and the proportions of patients categorized as having a low, intermediate, or high risk were 26.5%, 47.7% and 25.8%, respectively. The distribution of RS varied significantly according to different tumor grade, T stage, PR status, Ki-67 index and molecular subtypes(P<0.05 for all). Grade, PR status and Ki-67 index were independent predictive factors for RS. ER, PR status and Ki-67 index showed significantly correlation between RT-PCR and IHC assays, and the concordance rates for ER and PR status were 98.7% and 87.8%, respectively. Conclusions: RS significantly correlated with tumor grade, T stage, PR status, Ki-67 index and subtypes. Grade, PR status and Ki-67 index can independently predict RS. Remarkable concordances of ER, PR status and Ki-67 index are found between RT-PCR and IHC assays.

Abstract
Noble-metal nanomaterials are attracting increasing research interest due to their promising applications in electrochemical catalysis, for example. Although great efforts have been devoted to the size-, shape-, and architecture-controlled synthesis of noble-metal nanomaterials, their crystal-phase-controlled synthesis is still in its infancy. Here, for the first time, this study reports high-yield synthesis of Au nanorods (NRs) with alternating 4H/face-centered cubic (fcc) crystal-phase heterostructures via a one-pot wet-chemical method. The coexistence of 4H and fcc phases is relatively stable, and the 4H/fcc Au NRs can serve as templates for crystal-phase-controlled epitaxial growth of other metals. As an example, bimetallic 4H/fcc Au@Pd core-shell NRs are synthesized via the epitaxial growth of Pd on 4H/fcc Au NRs. Significantly, the 4H/fcc Au@Pd NRs show superior mass activity toward the ethanol oxidation reaction, i.e., 6.2 and 4.9 times those of commercial Pd black and Pt/C catalysts, respectively. It is believed that this new synthetic strategy can be used to prepare other novel catalysts for various promising applications.

Abstract
Inspired by the multiple functions of natural multienzyme systems, a new kind of hybrid nanosheet is designed and synthesized, i.e., ultrasmall Au nanoparticles (NPs) grown on 2D metalloporphyrinic metal-organic framework (MOF) nanosheets. Since 2D metalloporphyrinic MOF nanosheets can act as the peroxidase mimics and Au NPs can serve as artificial glucose oxidase, the hybrid nanosheets are used to mimic the natural enzymes and catalyze the cascade reactions. Furthermore, the synthesized hybrid nanosheets are used to detect biomolecules, such as glucose. This study paves a new avenue to design nanomaterial-based biomimetic catalysts with multiple complex functions.

Abstract
Objective: To investigate the effect of 21-gene recurrence score on adjuvant chemotherapy decisions for patients with estrogen receptor (ER)-positive, epidermal growth factor receptor 2 (HER-2)-negative and lymph node (LN)-negative early stage-breast cancer. Methods: One hundred and forty-eight patients with ER+ , HER-2- and LN- early stage breast cancer were recruited in the Ruijin hospital, Shanghai Jiao Tong University School of Medicine. The 21-gene recurrence score (RS)assay was performed and systemic therapeutic decisions were made before and after knowing the RS results under multidisciplinary discussion. The effects of RS assay and the other influential factors on adjuvant chemotherapy decision were further analyzed. Results: After knowing the RS results, treatment decisions were changed in 26 out of 148 patients(17.6%). Among them, 9 out of 26 patients were not recommended for chemotherapy; 16 of 26 had treatment recommendation changed to chemotherapy, and chemotherapy regimen was changed in the last one patient. Multivariate analysis showed that RS, age and histological grade were independent factors of decision-making for adjuvant chemotherapy. Conclusion: Our results suggest that 21-gene recurrence score significantly influences decision making for adjuvant chemotherapy in patients with ER+ , HER-2- and LN- early stage breast cancer.

Abstract
Objective: To study the prognostic factors of delayed gastric emptying(DGE) after pancreaticoduodenectomy(PD) and construct a prognostic predictive model for clinical application. Methods: Clinic data of 401 consecutive patients who underwent PD between January 2012 and July 2016 in the First Affiliated Hospital of Harbin Medical University were retrospectively collected and analyzed. The patients were randomly selected to modeling group(n=299) and validation group(n=102) at a ratio of 3∶1. The data of modeling group were subjected to univariate and multivariate analysis for prognostic factors and to construct a prognostic predictive model of DGE after PD. The data of validation group were applied to test the prognostic predictive model. Results: DGE after PD occurred in 35 of 299 patients(11.7%) in the modeling group. The multivariate analysis of the modeling group showed that upper abdominal operation history(χ(2)=6.533, P=0.011), diabetes mellitus(χ(2)=17.872, P=0.000), preoperative hemoglobin <90 g/L(χ(2)=14.608, P=0.000) and pylorus-preserving pancreaticoduodenectomy(PPPD)(χ(2)=8.811, P=0.003) were associated with DGE after PD independently. A prognostic predictive model of DGE after PD was constructed based on these factors and successfully tested. The area under the receiver operating characteristic(ROC) curve was 0.761(95%CI: 0.666-0.856) of the modeling group and 0.750(95% CI: 0.577-0.923) of the validation group. Conclusions: Upper abdominal operation history, diabetes mellitus, preoperative hemoglobin<90 g/L and PPPD are associated with DGE after PD independently. The preoperative assessment of a patient's prognostic for DGE after PD is feasible. The model is a valid tool to take precautions against DGE after PD.

Abstract
Abstract
Background: Nanoparticle albumin-bound paclitaxel (nab-Paclitaxel), a novel solvent-free taxane-based regimen, was hypothesized to have enhanced drug transport to tumors, shorter infusion schedules and no need for premedication. The value of nab-Paclitaxel in neoadjuvant systemic therapy (NST) for breast cancer remains uncertain. We performed a meta-analysis to assess efficacy and toxicity of nab-Paclitaxel compared to conventional taxane regimens (paclitaxel, docetaxel) within randomized clinical trials.
Methods: A systematic search was performed using the medical subject heading (MeSH) terms ''breast neoplasms'', as well as (1) breast cancer; AND (2) nab-Paclitaxel OR nanoparticle paclitaxel; AND (3) neoadjuvant OR preoperative OR primary systemic in both Pubmed databases and proceedings of oncologic meetings including ASCO, ESMO and SABCS. Pooled rates of pathological complete response(pCR), odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed-effect or random-effect model to determine the effect of neoadjuvant nab-paclitaxel.
Results: Twenty-one studies with 2357 patients were included, 3 of which (GeparSepto[1], ETNA[2], Showa trial[3]) were randomized clinical trials. The aggregate pCR rate (ypT0/is ypN0) was 32% (95% CI 25-38%) in unselected breast cancer patients and was 14%(95% CI 11-17%), 41%(95% CI 38-45%), 54%(95% CI 43-66%) in hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-), triple negative breast cancer(TNBC), HER2+ patients, respectively. Within the HER2+ population, pCR rate was 61%(95% CI 47-74%) for HR- and 40%(95% CI 28-52%) for HR+ tumors. Regarding randomized clinical trials, the probability of achieving pCR was significantly higher in the nab-paclitaxel group than in the conventional taxanes group (OR=1.383, 95%CI 1.141-1.676, p=0.001). A funnel plot of the effect size for each randomized trial against the precision showed no asymmetry, which indicating no potential publication bias. In the safety analysis (GeparSepto[1], ETNA[2]), hematological toxic effects were generally equivalent in nab-paclitaxel and paclitaxel group. For non-hematological toxic effects, all grades and grade≥ 3 peripheral sensory neuropathy occurred more frequently with nab-paclitaxel compared to paclitaxel (all grades, OR=2.090, 95%CI 1.016-4.302, p=0.045; grade≥ 3, OR=3.766, 95%CI 2.324-6.100, p<0.001). Hypersensitivity was more common with paclitaxel than nab-paclitaxel at any grade and grade≥ 3. Other non-hematological toxic effects did not significantly differ between two groups.
Conclusion: nab-Paclitaxel is an effective antitumor drug in NST of breast cancer, especially for TNBC and HER2+ tumors, in terms of pCR. Exchange of nab-Paclitaxel for conventional taxanes could significantly improve pCR rate with reasonable toxicities.
