Abstract
Climate dictates wildfire activity around the world. But East and Southeast Asia are an apparent exception as fire-activity variation there is unrelated to climatic variables. In subtropical China, fire activity decreased by 80% between 2003 and 2020 amid increased fire risks globally. Here, we assessed the fire regime, vegetation structure, fuel flammability and their interactions across subtropical Hubei, China. We show that tree basal area (TBA) and fuel flammability explained 60% of fire-frequency variance. Fire frequency and fuel flammability, in turn, explained 90% of TBA variance. These results reveal a novel system of scrubland-forest stabilized by vegetation-fire feedbacks. Frequent fires promote the persistence of derelict scrubland through positive vegetation-fire feedbacks; in forest, vegetation-fire feedbacks are negative and suppress fire. Thus, we attribute the decrease in wildfire activity to reforestation programs that concurrently increase forest coverage and foster negative vegetation-fire feedbacks that suppress wildfire.

Abstract
Two-dimensional (2D) ferromagnets have attracted widespread attention for promising applications in compact spintronic devices. However, the controlled synthesis of high-quality, large-sized, and ultrathin 2D magnets via facile, economical method remains challenging. Herein, we develop a hydrogen-tailored chemical vapor deposition approach to fabricating 2D Cr5Te8 ferromagnetic nanosheets. Interestingly, the time period of introducing hydrogen was found to be crucial for controlling the lateral size, and a Cr5Te8 single-crystalline nanosheet of lateral size up to ∼360 μm with single-unit-cell thickness has been obtained. These samples exhibit a leading role of domain wall nucleation in governing the magnetization reversal process, providing important references for optimizing the performances of associated devices. The nanosheets also show notable magnetotransport response, including nonmonotonous magnetic-field-dependent magnetoresistance and sizable anomalous Hall resistivity, demonstrating Cr5Te8 as a promising material for constructing high-performance magnetoelectronic devices. This study presents a breakthrough of large-sized CVD-grown 2D magnetic materials, which is indispensable for constructing 2D spintronic devices.

Abstract
The development and application of artificial intelligence have led to the exploitation of low-power and compact intelligent information-processing systems integrated with sensing, memory, and neuromorphic computing functions. The 2D van der Waals (vdW) materials with abundant reservoirs for arbitrary stacking based on functions and enabling continued device downscaling offer an attractive alternative for continuously promoting artificial intelligence. In this study, full 2D SnS2 /h-BN/CuInP2 S6 (CIPS)-based ferroelectric field-effect transistors (Fe-FETs) and utilized light-induced ferroelectric polarization reversal to achieve excellent memory properties and multi-functional sensing-memory-computing vision simulations are designed. The device exhibits a high on/off current ratio of over 105 , long retention time (>104 s), stable cyclic endurance (>350 cycles), and 128 multilevel current states (7-bit). In addition, fundamental synaptic plasticity characteristics are emulated including paired-pulse facilitation (PPF), short-term plasticity (STP), long-term plasticity (LTP), long-term potentiation, and long-term depression. A ferroelectric optoelectronic reservoir computing system for the Modified National Institute of Standards and Technology (MNIST) handwritten digital recognition achieved a high accuracy of 93.62%. Furthermore, retina-like light adaptation and Pavlovian conditioning are successfully mimicked. These results provide a strategy for developing a multilevel memory and novel neuromorphic vision systems with integrated sensing-memory-processing.

Abstract
Nonlayered two-dimensional (2D) magnets have attracted special attention, as many of them possess magnetic order above room temperature and enhanced chemical stability compared to most existing vdW magnets, which offers remarkable opportunities for developing compact spintronic devices. However, the growth of these materials is quite challenging due to the inherent three-dimensionally bonded nature, which hampers the study of their magnetism. Here, we demonstrate the controllable growth of air-stable pure γ-Fe2O3 nanoflakes by a confined-vdW epitaxial approach. The lateral size of the nanoflakes could be adjusted from hundreds of nanometers to tens of micrometers by precisely controlling the annealing time. Interestingly, a lateral-size-dependent magnetic domain configuration was observed. As the sizes continuously increase, the magnetic domain evolves from single domain to vortex and finally to multidomain. This work provides guidance for the controllable synthesis of 2D inverse spinel-type crystals and expands the range of magnetic vortex materials into magnetic semiconductors.

Abstract
Ferroelectrics are an integral component of the modern world and are of importance in electrics, electronics, and biomedicine. However, their usage in emerging wearable electronics is limited by inelastic deformation. We developed intrinsically elastic ferroelectrics by combining ferroelectric response and elastic resilience into one material by slight cross-linking of plastic ferroelectric polymers. The precise slight cross-linking can realize the complex balance between crystallinity and resilience. Thus, we obtained an elastic ferroelectric with a stable ferroelectric response under mechanical deformation up to 70% strain. This elastic ferroelectric exerts potentials in applications related to wearable electronics, such as elastic ferroelectric sensors, information storage, and energy transduction.

Abstract
Lipopolysaccharide (LPS), a core part of gram-negative bacteria, is crucial for inducing an inflammatory response in living things. In the current study, we used LPS from Salmonella to stimulate chicken macrophages (HD11). Proteomics was used to investigate immune-related proteins and their roles further. Proteomics investigation revealed 31 differential expression proteins (DEPs) after 4 hours of LPS infection. 24 DEPs expressions were up-regulated, while seven were down-regulated. In this investigation, ten DEPs were mainly enriched in S. aureus infection, complement, and coagulation cascades, which were all implicated in the inflammatory response and clearance of foreign pathogens. Notably, complement C3 was shown to be up-regulated in all immune-related pathways, indicating that it is a potential protein in this study. This work contributes to a better understanding and clarification of the processes of Salmonella infection in chickens. It might bring up new possibilities for treating and breeding Salmonella-infected chickens.

Abstract
PURPOSE Erectile dysfunction and COVID-19 share similar risk factors, including vascular disruption of integrity, cytokine release, cardiovascular disease, diabetes and obesity. The aim of this study was to investigate the association between erectile dysfunction and COVID-19 patients. METHODS Odds ratio for erectile dysfunction in patients with a history of COVID-19 with and without comorbidities were calculated using a patients' registry platform i2b2. ICD-10 diagnoses codes were accessed for queries and data were analyzed using logistic regression. RESULTS Patients with COVID-19 were 3.3 times more likely to have erectile dysfunction with 95% CI (2.8, 3.8). The association became stronger with odds ratio 4.8 (95% CI (4.1, 5.7)) after adjusting for age groups. The odds ratio remained the same after adjusting for smoking status with 3.5 (95% CI (3.0, 4.1)). After adjusting for race, COVID-19 patients were 2.6 (95% CI (2.2, 3.1)) times more likely to have erectile dysfunction. The odds ratio were 1.6, 1.8, 1.9 and 2.3 after adjusting for respiratory disease, obesity, circulatory disease and diabetes, respectively. CONCLUSION COVID-19 and erectile dysfunction are strongly associated even after adjustment for known risk factors and demographics.

Abstract
2D ferroelectrics with robust polar order in the atomic-scale thickness at room temperature are needed to miniaturize ferroelectric devices and tackle challenges imposed by traditional ferroelectrics. These materials usually have polar point group structure regarding as a prerequisite of ferroelectricity. Yet, to introduce polar structure into otherwise nonpolar 2D materials for producing ferroelectricity remains a challenge. Here, by combining first-principles calculations and experimental studies, it is reported that the native Ga vacancy-defects located in the asymmetrical sites in cubic defective semiconductor α-Ga2 Se3 can induce polar structure. Meanwhile, the induced polarization can be switched in a moderate energy barrier. The switched polarization is observed in 2D α-Ga2 Se3 nanoflakes of ≈4 nm with a high switching temperature up to 450 K. Such polarization switching could arise from the displacement of Ga vacancy between neighboring asymmetrical sites by applying an electric field. This work removes the point group limit for ferroelectricity, expanding the range of 2D ferroelectrics into the native defective semiconductors.

Abstract
OBJECTIVE To screen differentially expressed proteins (DSPs) in the liver tissues of patients with nonalcoholic steatohepatitis (NASH) using proteomic technologies to identify potential therapeutic targets of NASH. METHODS Liver tissue specimens were obtained from 3 patients with pathologically confirmed NASH and 3 normal control subjects. The total proteins were extracted from the specimens, and iTRAQ reagent was used to label the peptides for liquid chromatography tandem mass spectrometry (LC-MS/MS) detection. The DSPs were identified by comparing the data against UniProt protein database using Mascot2.3.02 software and were annotated and enriched using GO database; KEGG database was used for enrichment of the pathways involving these proteins. Real-time fluorescent quantitative PCR (qPCR) was performed to detect the mRNA expressions of the significant DSPs in NASH. RESULTS By the criteria that a DSP has >1.2 or < 0.8 fold difference between NASH group and the control group and with P < 0.05 as the threshold, a total of 648 significant DSPs in NASH were identified, including 246 up-regulated and 402 down-regulated proteins. GO functional enrichment analysis showed that the DSPs were involved mainly in small molecule metabolism, organic acid metabolism, oxygen acid metabolism and other biological processes, and were enriched in KEGG pathways including the metabolic pathways, complement coagulation cascades, and ribosomes. Among the 25 DEPs with a fold difference >2.0 or < 0.5 (P < 0.05), 6 proteins showed consistent results between qPCR verification and proteomic analysis, including 5 down-regulated proteins: Jumonji protein (JARID2), Lebasillinlike protein (LCA5L), synaptophysin 1 (SYN1) and collagen α-1 (XIII) chain (COL13A1), FYVE, RhoGEF and PH domain protein 5 (FGD5), and 1 upregulated protein glutathione S-transferase Mu 4 (GSTM4). CONCLUSION We identified 648 DEPs inthe liver tissue of patients NASH using iTRAQ technology and bioinformatics methods, and among them JARID2, SYN1, COL13A1, FGD5, and GSTM4 may serve as the key target proteins of NASH.

Abstract
OBJECTIVE To investigate the relationship between electrocardiographic changes and erythropoietin (EPO) level in stable coronary artery disease (CAD) patients with autonomic nerve functional damage. PATIENTS AND METHODS Clinical data of 96 stable CAD patients who were treated in our hospital from January 2017 to December 2019 were retrospectively analyzed. All patients were grouped according to whether autonomic nerve function damage was combined; the baseline characteristic data and the morphological characteristics of ECG scattergram were compared between 2 groups, and the relationship between ECG scattergram and EPO level & autonomic nerve function was analyzed. RESULTS The levels of EPO and red cell volume distributing width (RDW) in stable CAD patients with autonomic nerve dysfunction were significantly higher than that of CAD patients without autonomic nerve dysfunction (p<0.05). The length of scattergram in stable CAD patients with autonomic nerve dysfunction was significantly shorter than that of those without autonomic nerve dysfunction (p<0.05). The cometary sign proportion of ECG scattergram in stable CAD patients with autonomic nerve dysfunction was significantly lower than that of stable CAD patients without autonomic nerve dysfunction (p<0.05). There was negative correlation between EPO levels and scattergram length in stable CAD patients with and without autonomic nerve dysfunction (r=0.44, p=0.02). There was no correlation between EPO levels and scatter width in stable CAD patients with and without autonomic nerve dysfunction (r=0.10, p=0.58). The results of binary logistic regression analysis showed that EPO level was the independent risk factor for the occurrence of autonomic dysfunction in patients with stable CAD (p<0.05). The length of scattergram was the independent protective factor of autonomic nerve function impairment in patients with stable CAD (p<0.05). The AUC of EPO level and scattergram was 0.74 and 0.72 respectively, both of which have similar prediction value. CONCLUSIONS The level of EPO in stable CAD patients with autonomic nerve dysfunction was related to the change of ECG; and the EPO level and scattergram length can be used to predict the occurrence risk of autonomic nerve dysfunction.

Abstract
Atomically thin two-dimensional (2D) van der Waals materials have exhibited many exotic layer-dependent physical properties including electronic structure, magnetic order, etc. Here, we report a striking even-odd layer dependent oscillation in the ferroelectric polarization of 2H-stacked few-layer α-In2Se3 nanoflakes. As characterized by piezoresponse force microscopy (PFM), when the in-plane (IP) electric polarization of 2H-stacked α-In2Se3 films is electrically aligned, the out-of-plane (OOP) polarization of the odd-layer (OL) samples is obviously larger than that of the even-layer (EL) ones. Similarly, samples with electrically aligned OOP polarization also show even-odd layer dependent IP polarization. Such an even-odd oscillation, as confirmed by the density functional theory calculations, can be attributed to the strong intercorrelation of the IP and OOP electric polarization of the α-In2Se3 monolayers and the special 2H-stacking structure of a 180 degree IP rotation with respect to the adjacent layers. Moreover, a negative differential resistance, interestingly, is induced by the polarization flip with a small coercive field of ∼1.625 kV cm-1, and its peak-to-valley ratio can be tuned up to ∼7 by the gate. This work demonstrates that the delicate stacking geometry of multilayer α-In2Se3 can bring an interesting even-odd ferroelectric effect, enriching the layer-dependent physical properties of the 2D materials family.

Abstract
The control of magnetism by electric means in single-phase multiferroic materials is highly desirable for the realization of next-generation magnetoelectric (ME) multifunctional devices. Nevertheless, most of these materials reveal either low working temperature or antiferromagnetic nature, which severely limits the practical applications. Herein, we selected room-temperature multiferroic Ga0.6Fe1.4O3 (GFO) with ferrimagnetism to study electric-field-induced nanoscale magnetic domain reversal. The GFO thin film fabricated on the (111)-orientated Nb-doped SrTiO3 single-crystal substrate was obtained through the pulsed laser deposition method. The test results indicate that the thin film not only exhibits ferroelectricity but also ferrimagnetism at room temperature. More importantly, reversible and nonvolatile nanoscale magnetic domains reversal under pure electrical fields is further demonstrated by taking advantage of its ME coupling effect with dependent origins based on iron ions. When providing an appropriate applied voltage, clear magnetic domain structures with large size can be easily manipulated. Meanwhile, the change ratio of the electrically induced magnetizations in the defined areas can reach up to 72%. These considerable merits of the GFO thin film may provide a huge potential in the ME multifunctional devices, such as the multi-value, low-energy-consuming, and nonvolatile memory and beyond.

Abstract
Abstract
Background
Statins remain a standard treatment for acute coronary syndrome (ACS) patients. We aimed to determine the association between different dosages of in-hospital statins and the prognoses among patients receiving percutaneous coronary intervention (PCI).
Methods
NSTE-ACS patients were retrospectively enrolled from January 2010 to December 2014 from five centres in China. Patients receiving either atorvastatin or rosuvastatin during their hospitalizations were included. All the patients were categorized into high-dose statin group (40mg atorvastatin or 20mg rosuvastatin) or low-dose statin group (20mg atorvastatin or 10mg rosuvastatin). In-hospital events and long-term all-cause death was recorded.
Results
Of the 7,008 patients included in the study, 5,248 received low-dose intensive statin (mean age: 64.28±10.39; female: 25.2%), and 1,760 received high-dose intensive statin (mean age: 63.68±10.59; female: 23.1%). There was no significant difference in in-hospital all-cause death between the two groups (adjusted OR, 1.27; P=0.665). All-cause death was similar between the two groups during the long-term follow-up period (30-day: adjusted HR, 1.28; P=0.571; 3-year: adjusted HR, 0.83; P=0.082). However, there was a robust association between the high-dose statin and the reduction in in-hospital dialysis (adjusted OR, 0.11; P=0.030).
Conclusions
The in-hospital high-dose intensive statin is not associated with lower risks of in-hospital or follow-up all-cause death in NSTE-ACS patients undergoing PCI. Considering the robust beneficial effect of in-hospital dialysis, an individualized high-dose intensive statin can be rational in specified populations.

Abstract
Abstract
Casestudy
Epstein-Barr virus (EBV)-associated peripheral T-cell lymphomas are a group of aggressive neoplasms with a geographic predilection for South America and Asia, but are very rare in Western populations.
Results
We report a case of a 74-year-old Caucasian female who presented with pancytopenia and B symptoms with EBV-IgG detected on admission. Past medical history included: ITP, chronic urticaria, and recently diagnosed myelodysplastic syndrome (MDS) on bone marrow biopsy one month prior to admission. Excisional biopsies of an enlarged right neck lymph node (repeated within 6 months) and right axillary lymph node five years ago were negative for a lymphoproliferative disorder at the time. Repeated bone marrow biopsy, performed during the current admission, confirmed the diagnosis of MDS, with scattered T-cells without aberrant immunophenotype. Despite aggressive treatment from multiple specialties, the patient deteriorated and expired four weeks later from complications of MDS. At autopsy, there was diffuse lymphadenopathy involving the mediastinum, axilla, pelvis and peripancreatic fat. Lymph node sections demonstrated nodal architecture effacement by diffuse, vaguely nodular lymphoid infiltrates.
Histologically, the infiltrates were composed of medium to large lymphocytes with round to slight irregular nuclei, rare Reed-Sternberg-like multinucleated cells, clumped chromatin, and indistinct nucleoli. Individual cell necrosis was abundant with mitotic figures readily identifiable. Immunohistochemistry revealed CD2+ CD3+ neoplastic T-cells that co-express MUM1 and a subset of CD30, while negative for CD4, CD5, CD8, CD56, ALK1, and TDT. EBV-encoded RNA in-situ hybridization was focally positive. The final postmortem diagnosis was peripheral T-cell lymphoma, not otherwise specified (NOS), with focal EBV positivity.
Conclusion
Co-existence of a de-novo MDS and non-Hodgkin lymphoma without any prior chemotherapeutic exposure is a highly unusual finding, although MDS-like presentations can occur with EBV-associated lymphomas. Peripheral T-cell lymphoma, NOS is an aggressive lymphoma and EBV positivity has been found correlated with a poor prognosis. This case demonstrates how postmortem examination remains an important tool in clinical- pathological correlation and highlights the potential pathogenetic role EBV plays in MDS and T-cell lymphoma.

Abstract
BACKGROUND Previously published data on the association between the XRCC1 Arg194Trp polymorphism and thyroid cancer (TC) remain controversial. METHODS To clarify the association between the XRCC1 Arg194Trp polymorphism and susceptibility to TC, a meta-analysis of case-control studies was conducted. We systematically searched PubMed and CNKI to identify relevant studies. Pooled odds ratios (ORs) of various genetic models were estimated using fixed and random effects models. Heterogeneity was detected by Q-statistic, and the Egger's test was used to evaluate the publication bias. RESULTS A total of seven eligible studies for the XRCC1 Arg194Trp polymorphism (1500 patients and 2358 controls) were included in this meta-analysis. The results of our study failed to suggest an association between the Arg194Trp polymorphism and susceptibility of TC. However, in the subgroup analyses by ethnicity, the OR was 0.82 (C allele vs. T allele, 95% CI 0.68-0.98; P = 0.24 for heterogeneity) among the Chinese population. Nevertheless, no significant differences were observed in the Caucasian population in any genetic model. CONCLUSION This study suggested that the C allele of XRCC1 had an 18% significantly decreased risk of TC in Chinese, and there were no significant associations among Caucasians under all genetic models.

Abstract
The rapid development of artificial intelligence techniques and future advanced robot systems sparks emergent demand on the accurate perception and understanding of the external environments via visual sensing systems that can co-locate the self-adaptive detecting, processing, and memorizing of optical signals. In this contribution, a simple indium-tin oxide/Nb-doped SrTiO3 (ITO/Nb:SrTiO3) heterojunction artificial optoelectronic synapse is proposed and demonstrated. Through the light and electric field co-modulation of the Schottky barrier profile at the ITO/Nb:SrTiO3 interface, the oxide heterojunction device can respond to the entire visible light region in a neuromorphic manner, allowing synaptic paired-pulse facilitation, short/long-term memory, and "learning-experience" behavior for optical information manipulation. More importantly, the photoplasticity of the artificial synapse has been modulated by heterosynaptic means with a sub-1 V external voltage, not only enabling an optoelectronic analog of the mechanical aperture device showing adaptive and stable optical perception capability under different illuminating conditions but also making the artificial synapse suitable for the mimicry of interest-modulated human visual memories.

Abstract
Memristors with enormous storage capacity and superior processing efficiency are of critical importance to overcome the Moore’s Law limitation and von Neumann bottleneck problems in the big data and artificial intelligence era. In particular, the integration of multifunctionalities into a single memristor promises an essential strategy of obtaining a high-performance electronic device that satisfies the nowadays increasing demands of data storage and processing. In this contribution, we report a proof-of-concept polymer memristive processing-memory unit that demonstrates programmable information storage and processing capabilities. By introducing redox active moieties of triphenylamine and ferrocene onto the pendants of fluorene skeletons, the conjugated polymer exhibits triple oxidation behavior and interesting memristive switching characteristics. Associated with the unique electrochemical and electrical behavior, the polymer device is capable of executing multilevel memory, decimal arithmetic operations of addition, subtraction, multiplication and division, as well as simple Boolean logic operations. Though designing conductive polymers for memory devices is attractive for future low-cost flexible electronics, a proof-of-concept device has yet to be realized. Here, the authors report a redox-gated polymer memristive processing unit with programmable multilevel storage and logic functionalities.

Abstract
1. This study determined the effects of (E)-3-(2-(4-(3-(2,4-dimethoxyphenyl)acryloyl)phenoxy)ethoxy)-5,7-dimethoxy-2-(3,4,5-trimethoxyphenyl)-4H-chromen-4-one (EDACO) on the differentiation of Gaoyou duck embryonic osteoclasts cultured in vitro. 2. Bone marrow mononuclear cells (BM-MNC) were collected from 23-d-old Gaoyou duck embryos and induced by macrophage colony-stimulating factor and receptor activator of nuclear factor κB ligand in the presence of EDACO at different concentrations (i.e. 10, 20, 40, 80 and 160 µM). Tartrate-resistant acid phosphatase (TRAP) staining and resorption ability determination were conducted. 3. Results suggested that EDACO suppressed the shaping of positive multinucleated cells and the number of TRAP-positive cells in the 20, 40, 80 and 160 μM EDACO groups was significantly decreased (P < 0.05 or P < 0.01). Besides, the absorption activity of differentiated duck embryonic osteoclasts was significantly inhibited (P < 0.05) in both 80 and 160 μM EDACO groups. 4. Overall, EDACO can inhibit the differentiation of BM-MNC into mature osteoclasts in duck embryos.1.

Abstract
Objective: To analyze the clinical characteristics of IgG4-related disease (IgG4-RD)so as to improve the understanding of IgG4-RD in China. Methods: IgG4-RD patients were recruited from Peking Union Medical College Hospital between January 2011 and January 2016. All patients were followed-up for more than 6 months. The demographic characteristics, symptoms, organ involvements, laboratory examinations and treatment efficacy were evaluated and analyzed. Results: A total of 346 patients were finally enrolled, including 230 males (66.5%) and 116 females (33.5%). The mean age of disease onset was (53.8±14.2) years old. The mostly common involved organs were lymph nodes (56.4%) and submandibular glands (52.6%). Other affected organs and manifestations included: swelling of the lacrimal glands (46.5%), autoimmune pancreatitis (38.4%), pulmonary involvement (28.0%), sclerosing cholangitis (25.4%), naso-sinusitis (23.4%), parotid gland swelling (21.7%), retroperitoneal fibrosis (19.9%), large arteries involvement (9.5%), kidney involvement (obstructive nephropathy caused by retroperitoneal fibrosis was excluded) (6.9%), skin lesions (6.4%). Rare features consisted of thyroid glands, pituitary glands, gastrointestinal tract, pachymeningitis, pericardium, sclerosing mediastinitis and orchitis. The majority of patients had multi-organ involvement, such as 74.3% patients with 3 and more, 18.2% and 7.5% patients with 2 and single organ involvement respectively. The average IgG4-RD responder index (IgG4-RD RI) was 13.21±5.70. History of allergy was found in 172 (49.7%) patients. As to the laboratory tests, elevated serum IgG4 levels were confirmed in 285 (94.1%) patients, which was positively correlated with IgG4-RD RI. There were 33.5% patients receiving monotherapy of glucocorticoid, 52.6% treated with glucocorticoids combined with immunosuppressive agents, 4.9% patients with immunosuppressant only, and 9.0% patients with mild disease not receiving medication. The majority (336, 97.1%) patients improved the above regimens. Conclusion: IgG4-RD is a systemic fibro-inflammatory disease with multiple organ involvement. The mostly common involved organs include lymph node, submandibular glands, and pancreas. Glucocorticoids and immunosuppressive agents were effective for IgG4-RD.

Abstract
PURPOSE The aim of this study was to determine the effects of different menopausal hormone therapy regimens on body composition in healthy postmenopausal Chinese women. MATERIALS AND METHODS One hundred and twenty-three healthy postmenopausal Chinese women were randomly assigned to either group A (0.625 mg conjugated equine estrogens [CEE] plus 100 mg micronized progesterone [MP]), group B (0.3 mg CEE plus 100 mg MP), or group C (0.625 mg CEE plus 10 mg dydrogesterone). Body composition was assessed by dual-energy X-ray absorptiometry. RESULTS One hundred and two women completed the trial at 1 year. A small but significant gain in lean body mass (619 ± 1019 g, p = 0.002) and a decrease of fat mass in all separate regions was observed in group A. A significant shift from gynoid to android fat distribution was observed in group B and group C (android/gynoid fat percentage ratios increased by 0.06 ± 0.08, p = 0.000 and 0.03 ± 0.08, p = 0.018, respectively), whereas no significant change was observed in group A (0.02 ± 0.06, p = 0.103). CONCLUSIONS In healthy postmenopausal Chinese women, 0.625 mg of CEE combined with 100 mg of MP was associated with a more favorable fat distribution compared with 0.3 mg CEE plus 100 mg MP or 0.625 mg CEE plus 10 mg dydrogesterone.

Abstract
The seed oil of 138 accessions of 14 Acer truncatum (Aceraceae family) populations native to China were analyzed by pulsed nuclear magnetic resonance spectroscopy and gas chromatography-flame ionization detection. The oil content ranged from 17.81% to 36.56% (mean: 28.57%), which mainly consisted of 14 types of fatty acids. Palmitic (4.69%), stearic (2.30%), oleic (25.19%), linoleic (32.97%), linolenic (2.76%), cis-11-eicosenoic (7.90%), erucic (16.49%), and nervonic (5.76%) fatty acids accounted for 98% of total fat. The nervonic acid content ranged from 3.90% to 7.85% among the accessions. Significant variations in oil content and predominating fatty acids were observed among populations. Hierarchical cluster analysis and principal component analysis detected obvious geographical variation trends among A. truncatum populations which correlate with environmental variations (especially altitude, temperature, and precipitation) and supported the grouping of the populations into three groups according to geographic locations.

Abstract
Objective: Using a questionnaire to evaluate different regimens of chemotherapy on ovarian function and quality of life of patients with gestational trophoblastic neoplasia (GTN) . Methods: At least 6 months after completion of chemotherapy, 200 patients with GTN treated in Peking Union Medical College Hospital from January 2010 to June 2017 were randomly selected to fill up the questionnaire. The questionnaire items were included the patient's menstrual cycles, sexual life, gestational issues and common health. The patients were divided into 3 groups by chemotherapy regimens: actinomycin D (Act-D) group, floxuridine+Act-D+vincristine (FAV) or floxuridine+Act-D+etoposide+vincristine (FAEV) group (FAV-FAEV group) , and etoposide+methotrexate+Act-D (EMA) /vincristine+cyclophosphamide (CO) or EMA/ etoposide+cisplatin (EP) group (EMA/CO-EMA/EP group) . Chi-square test was used with a significance level of P-value less than 0.05. Results: One hundred and seventy-three (86.5%,173/200) of the patients completed the questionnaire. Forty three point two percent (43.2%, 19/44) in the EMA/CO-EMA/EP group had a normal menstrual cycle, which were significantly lower than those of Act-D group (84.6%,22/26) and FAV-FAEV group (71.2%, 37/52; all P<0.05) . Amenorrhea rate was also significantly higher in EMA/CO-EMA/EP group (25.0%, 11/44) than in Act-D group (0) and FAV-FAEV group (17.3%, 9/52; all P<0.05) . The sexual life parameters were comparable among 3 groups. Ten out of thirty-two patients conceived after chemotherapy, 2 had miscarriages and 8 had full-term delivery of healthy babies. The common health and labor capacity were significantly decreased after chemotherapy (all P<0.05) . Conclusions: EMA/CO or EMA/EP regimen have a worse impact on ovarian function than Act-D and FAV or FAEV regimen. Gynecologic oncologist should be concerned about the ovarian function and quality of life of GTN patients.

Abstract
OBJECTIVE To evaluate the prevalence of breast tenderness in a population treated with menopausal hormone therapy (MHT) or Cimicifuga foetida extract. METHODS A prospective, randomized, controlled trial was conducted. Ninety-six postmenopausal women were randomly assigned to three groups: group A, 1 mg estradiol valerate daily plus 4 mg medroxyprogesterone acetate (MPA), days 19-30; group B, 1 mg estradiol valerate daily plus 100 mg micronized progesterone (MP), days 19-30; group C, 100 mg C. foetida extract daily. Breast tenderness was evaluated daily for 12 months. RESULTS Seventy-three patients completed the study. Group A had the highest prevalence of breast tenderness, while group C had the lowest. More than 50% of all participants reported no symptoms throughout the period. The participants in group A experienced a sharp increase in breast tenderness after treatment, but decreased after 1 month. No significant decline was found in the duration of pain in group B. The patients in group C reported no remarkable changes after 1 month. Compared to estrogen only, estrogen plus MPA/MP led to a higher incidence of prolonged breast symptoms. CONCLUSIONS Compared to MHT groups, C. foetida extract had the lowest prevalence of breast tenderness. Most participants experienced mild or no symptoms.

Abstract
Objective: To investigate the efficacy and drug related adverse reactions of sorafenib and sunitinib as first-line tyrosine-kinase inhibitors (TKIs) for patients with metastatic renal cell carcinoma (mRCC) and analyze the clinical prognostic factor for survival. Methods: The data of 271 patients with metastatic renal cell carcinoma who had complete clinicopathological data were retrospectively analyzed, including 174 cases in sorafenib group and 97 cases in sunitinib group, to access patients' overall survival (OS) and progression-free survival (PFS). Prognostic values of all characteristics were determined by using univariate and multivariate Cox regression models. Results: The objective response rates (ORR) of the sorafenib and sunitinib groups were 14.9% and 19.6%, respectively, and the disease control rates (DCR) were 85.1% and 88.6%, respectively. No significant difference was found between the sorafenib and sunitinib group in ORR (P=0.325) or DCR (P=0.408). The most common grade 3 to 4 adverse events in the sorafenib group were hand-foot syndrome (6.7%), diarrhea (2.3%), and rash (2.3%). The most common grade 3 to 4 adverse events in the sunitinib group were neutropenia (6.2%), hand-foot syndrome (6.2%), and thrombocytopenia (4.6%). During the follow-up, 97 cases death occurred and 81 cases disease progression occurred in sorafenib group. The median PFS was 12 months (95% CI: 9-15 months), and the median OS was 25 months (95% CI: 21-29 months) in sorafenib group. While 74 cases death occurred and 40 cases disease progression occurred in sunitinib group, the median PFS was 12 months (95% CI: 10-12 months) and the median OS was 23 months (95% CI: 20-32 months) in sunitinib group. No significant difference was found between the sorafenib and the sunitinib group in PFS (P=0.771) or OS (P=0.548). Multivariate analysis showed Fuhrman grades (HR=1.358, 95%CI: 1.004-1.835), number of metastatic sites (HR=1.550, 95%CI: 1.143-2.101) and MSKCC risk grade (Intermediate risk group: HR=1.621, 95%CI: 1.117-2.232; Poor risk group: HR=2.890, 95%CI: 1.942-4.298) were independent prognostic factors for PFS. Fuhrman grades (HR=2.135, 95%CI: 1.533-2.974), number of metastatic sites (HR=1.774, 95%CI: 1.279-2.461) and MSKCC risk grade (Intermediate risk group: HR=1.415, 95%CI: 1.002-1.998; Poor risk group: HR=3.161, 95%CI: 2.065-4.838) were independent prognostic factors for OS. Conclusions: The results of this study indicate that sorafenib and sunitinib are both effective as the first-line TKIs for mRCC patients and sorafenib has comparable efficacy to sunitinib. But they have differences in the incidence of adverse effects. Fuhrman grades, number of metastatic sites and MSKCC risk grade are independent prognostic factors for mRCC patients.

Abstract
Resistive random access memory (RRAM) with inherent logic-in-memory capability exhibits great potential to construct beyond von-Neumann computers. Particularly, unipolar RRAM is more promising because its single polarity operation enables large-scale crossbar logic-in-memory circuits with the highest integration density and simpler peripheral control circuits. However, unipolar RRAM usually exhibits poor switching uniformity because of random activation of conducting filaments and consequently cannot meet the strict uniformity requirement for logic-in-memory application. In this contribution, a new methodology that constructs cone-shaped conducting filaments by using chemically a active metal cathode is proposed to improve unipolar switching uniformity. Such a peculiar metal cathode will react spontaneously with the oxide switching layer to form an interfacial layer, which together with the metal cathode itself can act as a load resistor to prevent the overgrowth of conducting filaments and thus make them more cone-like. In this way, the rupture of conducting filaments can be strictly limited to the tip region, making their residual parts favorable locations for subsequent filament growth and thus suppressing their random regeneration. As such, a novel "one switch + one unipolar RRAM cell" hybrid structure is capable to realize all 16 Boolean logic functions for large-scale logic-in-memory circuits.

Abstract
AIM To evaluate prospectively the performance of combining morphological and arterial spin labelling (ASL) magnetic resonance imaging (MRI) for detecting pseudocapsule defects in renal cell carcinoma (RCC), and to predict renal capsule invasion confirmed histopathologically. MATERIALS AND METHODS Twenty consecutive patients with suspicious renal tumours underwent MRI. Renal ASL imaging was performed and renal blood flow was measured quantitatively. The diagnostic performance of T2-weighted images alone, and a combination of T2-weighted and ASL images for predicting renal capsule invasion were assessed. RESULTS Twenty renal lesions were evaluated in 20 patients. All lesions were clear cell RCCs (ccRCCs) confirmed at post-surgical histopathology. Fifteen ccRCCs showed pseudocapsule defects on T2-weighted images, of which 12 cases showed existing blood flow in defect areas on perfusion images. To predict renal capsule invasion, the sensitivity, specificity, positive predictive value, and negative predictive value were 100%, 71.4%, 86.7%, 100%, respectively, for T2-weighted images alone, and 92.3%, 100%, 100%, 87.5%, respectively, for the combination of T2-weighted and ASL images. CONCLUSION ASL images can reflect the perfusion of pseudocapsule defects and as such, the combination of T2-weighted and ASL images produces promising diagnostic accuracy for predicting renal capsule invasion.

Abstract
Nanoscale manipulation of materials' physicochemical properties offers distinguished possibility to the development of novel electronic devices with ultrasmall dimension, fast operation speed, and low energy consumption characteristics. This is especially important as the present semiconductor manufacturing technique is approaching the end of miniaturization campaign in the near future. Here, a superior metal-insulator transition (MIT) of a 1D VO2 nanochannel constructed through an electric-field-induced oxygen ion migration process in V2 O5 thin film is reported for the first time. A sharp and reliable MIT transition with a steep turn-on voltage slope of <0.5 mV dec-1 , fast switching speed of 17 ns, low energy consumption of 8 pJ, and low variability of <4.3% is demonstrated in the VO2 nanochannel device. High-resolution transmission electron microscopy observation and theoretical computation verify that the superior electrical properties of the present device can be ascribed to the electroformation of nanoscale VO2 nanochannel in V2 O5 thin films. More importantly, the incorporation of the present device into a Pt/HfO2 /Pt/VO2 /Pt 1S1R unit can ensure the correct reading of the HfO2 memory continuously for 107 cycles, therefore demonstrating its great possibility as a reliable selector in high-density crossbar memory arrays.

Abstract
BACKGROUND AND PURPOSE Intracerebral hemorrhage accounts for 6.5%-19.6% of all acute strokes. Initial intracerebral hemorrhage volume and expansion are both independent predictors of clinical outcomes and mortality. Therefore, a rapid, unbiased, and precise measurement of intracerebral hemorrhage volume is a key component of clinical management. The most commonly used method, ABC/2, results in overestimation. We developed an interactive segmentation program, SegTool, using a novel graphic processing unit, level set algorithm. Until now, the speed, bias, and precision of SegTool had not been validated. MATERIALS AND METHODS In a single stroke academic center, 2 vascular neurologists and 2 neuroradiologists independently performed a test-retest experiment that involved repeat measurements of static, unchanging intracerebral hemorrhage volumes on CT from 76 intracerebral hemorrhage cases. Measurements were made with SegTool and ABC/2. True intracerebral hemorrhage volumes were estimated from a consensus of repeat manual tracings by 2 operators. These data allowed us to estimate measurement bias, precision, and speed. RESULTS The measurements with SegTool were not significantly different from the true intracerebral hemorrhage volumes, while ABC/2 overestimated volume by 45%. The interrater measurement variability with SegTool was 50% less than that with ABC/2. The average measurement times for ABC/2 and SegTool were 35.7 and 44.6 seconds, respectively. CONCLUSIONS SegTool appears to have attributes superior to ABC/2 in terms of accuracy and interrater reliability with a 9-second delay in measurement time (on average); hence, it could be useful in clinical trials and practice.

Abstract
Flexible and transparent resistive switching memories are highly desired for the construction of portable and even wearable electronics. Upon optimization of the microstructure wherein an amorphous-nanocrystalline hafnium oxide thin film is fabricated, an all-oxide based transparent RRAM device with stable resistive switching behavior that can withstand a mechanical tensile stress of up to 2.12% is obtained. It is demonstrated that the superior electrical, thermal and mechanical performance of the ITO/HfOx/ITO device can be ascribed to the formation of pseudo-straight metallic hafnium conductive filaments in the switching layer, and is only limited by the choice of electrode materials. When the ITO bottom electrode is replaced with platinum metal, the mechanical failure threshold of the device can be further extended.
