Abstract
TheH-Tphase diagram of Ni3V2O8is very rich and remains puzzling in a high magnetic field range. Through the state-of-the-art specific heat measurement in pulsed high field to 35 T and magnetocaloric effect measurement up to 45 T, we successfully construct the high-field phase diagram of Ni3V2O8for fields applied along thebaxis. The phase boundaries are corrected for previous results by magnetization and magneto-optical measurements. The resulting phase diagram shows that the high temperature incommensurate (HTI) phase develops well to high fields and low temperatures. In addition to the early reported C', C, low temperature incommensurate (LTI) and HTI phases, we explore a new magnetic ordered phase called HF1 in fields of 10-30 T. A multicritical point is also observed at 6 K and 8 T. Furthermore, the specific heat data reveal enhancements of the anomalies at ∼4 K, probably associated with a strong spin-lattice coupling in this frustrated multiferroic material.

Abstract
Objectives: The mortality rate of sepsis remains very high. Metabolomic techniques are playing increasingly important roles in diagnosis and treatment in critical care medicine. The purpose of our research was to use untargeted metabolomics to identify and analyze the common differential metabolites among patients with sepsis with differences in their 7-day prognosis and blood PD-1 expression and analyze their correlations with environmental factors. Methods: Plasma samples from 18 patients with sepsis were analyzed by untargeted LC-MS metabolomics. Based on the 7-day prognoses of the sepsis patients or their levels of PD-1 expression on the surface of CD4+ T cells in the blood, we divided the patients into two groups. We used a combination of multidimensional and monodimensional methods for statistical analysis. At the same time, the Spearman correlation analysis method was used to analyze the correlation between the differential metabolites and inflammatory factors. Results: In the positive and negative ionization modes, 16 and 8 differential metabolites were obtained between the 7-day death and survival groups, respectively; 5 and 8 differential metabolites were obtained between the high PD-1 and low PD-1 groups, respectively. We identified three common differential metabolites from the two groups, namely, PC (P-18:0/14:0), 2-ethyl-2-hydroxybutyric acid and glyceraldehyde. Then, we analyzed the correlations between environmental factors and the common differences in metabolites. Among the identified metabolites, 2-ethyl-2-hydroxybutyric acid was positively correlated with the levels of IL-2 and lactic acid (Lac) (P < 0.01 and P < 0.05, respectively). Conclusions: These three metabolites were identified as common differential metabolites between the 7-day prognosis groups and the PD-1 expression level groups of sepsis patients. They may be involved in regulating the expression of PD-1 on the surface of CD4+ T cells through the action of related environmental factors such as IL-2 or Lac, which in turn affects the 7-day prognosis of sepsis patients.

Abstract
OBJECTIVE To detect the expression of long non-coding ribonucleic acid (lncRNA) ASB16-AS1 in non-small cell lung cancer (NSCLC) tissues and cells, and to explore the effect of lncRNA ASB16-AS1 on the biological functions of NSCLC cells. PATIENTS AND METHODS The expression level of lncRNA ASB16-AS1 in NSCLC tissues and cells was detected via real-time fluorescence quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). The interference sequences of lncRNA ASB16-AS1 were designed and synthesized, and its transfection efficacy was detected by qRT-PCR. After knockdown of lncRNA ASB16-AS1, the proliferation, cell cycle, and apoptosis of NSCLC cells were detected via cell counting kit-8 (CCK-8) assay, colony formation assay, and flow cytometry, respectively. Moreover, the expression changes in the Wnt/β catenin signaling pathway were detected via Western blotting. RESULTS LncRNA ASB16-AS1 was upregulated in NSCLC tissues and cells compared with that in paracarcinoma tissues and 16HBE cells. The results of CCK-8 assay and colony formation assay revealed that the silence of lncRNA ASB16-AS1 attenuated the proliferative ability in NSCLC. The results of flow cytometry manifested that the silence of lncRNA ASB16-AS1 arrested the cell cycle in G0/1 phase, and accelerated the apoptosis rate. The key proteins in the Wnt/β-catenin signaling pathway were regulated by lncRNA ASB16-AS1 in NSCLC. CONCLUSIONS LncRNA ASB16-AS1 is upregulated in NSCLC tissues and cells, which promotes proliferation and inhibits apoptosis of NSCLC cells through the Wnt/β-catenin signaling pathway.

Abstract
Objective: To investigate the diagnostic value of apparent diffusion coefficient (ADC) histogram in quantifying moderate to severe neonatal hypoxic-ischemic encephalopathy (HIE). Methods: A total of 49 children with moderate to severe HIE admitted to the Children's Hospital Affiliated to Nanjing Medical University from July 2015 to September 2018 were retrospectively analyzed. Cranial magnetic resonance imaging (MRI) data of 31 full-term neonates without neurological symptoms and signs who visited the hospital during the same period were recruited as the control group. ImgJ software was used to delineate the whole brain area at the thalamus/basal ganglia level as the area of interest, and MRIcron software was used to obtain ADC histogram parameters. The differences of ADC histogram parameters between HIE group and control group were compared. The correlation between ADC histogram parameters and neonatal neurobehavioral neurological assessment (NBNA) in HIE group was analyzed. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficiency of each parameter. Results: The mean value, minimum value, maximum value, mode-value, variance, heterogeneity and 10%-90% ADC values of HIE group were all greater than those of the control group(634±65,310±36,1 683±18,711±87,66 928±921,5 907±204,477±50,513±53,542±56,568±59,591±61,625±92,661±97,709±105,811±119),the differences were statistically significant(all P<0.05), while mode-count of HIE group was smaller than that of the control group(272±22 to 395±83), and the difference was statistically significant (t=2.996,P<0.05). All the above parameters with statistical differences were correlated with NBNA score, among which mode-count was negatively correlated with NBNA score(r=-0.369,P<0.05), and the rest were positively correlated(all P<0.05). The area under the ROC curve (AUC) of variance had the highest diagnostic efficiency (0.881), followed by 90% ADC value and ADC maximum value. Conclusion: ADC histogram is helpful for the diagnosis of HIE, objectively and quantitatively reflecting the diffusion information of brain, and assessing the severity of HIE.

Abstract
The electron valley and spin degree of freedom in monolayer transition-metal dichalcogenides can be manipulated in optical and transport measurements performed in magnetic fields. The key parameter for determining the Zeeman splitting, namely, the separate contribution of the electron and hole g factor, is inaccessible in most measurements. Here we present an original method that gives access to the respective contribution of the conduction and valence band to the measured Zeeman splitting. It exploits the optical selection rules of exciton complexes, in particular the ones involving intervalley phonons, avoiding strong renormalization effects that compromise single particle g-factor determination in transport experiments. These studies yield a direct determination of single band g factors. We measure g_{c1}=0.86±0.1, g_{c2}=3.84±0.1 for the bottom (top) conduction bands and g_{v}=6.1±0.1 for the valence band of monolayer WSe_{2}. These measurements are helpful for quantitative interpretation of optical and transport measurements performed in magnetic fields. In addition, the measured g factors are valuable input parameters for optimizing band structure calculations of these 2D materials.

Abstract
OBJECTIVE The aim of this study was to analyze the association of ATPase plasma membrane Ca2+ transporting 1 (ATP2B1) gene polymorphism with the incidence of eclampsia, and to investigate the possible underlying mechanism. PATIENTS AND METHODS ATP2B1 genotype and allele distributions in umbilical venous blood cells were analyzed in 50 control subjects and 117 eclampsia patients via Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and TaqMan genotyping technique. Meanwhile, the differences in the single nucleotide polymorphisms at rs2681472 and rs17249754 in the case group and control group were analyzed using the χ2-test. The risk factors for eclampsia were analyzed via univariate, multivariate, and Logistic regression analyses. Furthermore, the associations of rs2681472 gene polymorphism with risk factors for eclampsia (hypertension and lower extremity edema) were verified via χ2-test. RESULTS The statistically significant differences were observed in the gestational week, body mass index, blood pressure, and incidence rates of proteinuria and lower extremity edema of pregnant women between the case group and the control group (p<0.05). Meanwhile, the genotype and allele distributions at rs2681472 in the case group were remarkably different from those of the control group (p<0.05). However, no evident differences were observed at rs17249754 between the two groups (p>0.05). According to univariate, multivariate, and logistic regression analyses, hypertension, and lower extremity edema were significantly associated with the incidence of eclampsia (p<0.05). In addition, the gene polymorphism at rs2681472 showed significant differences among subjects with and without hypertension and lower extremity edema (p<0.05). CONCLUSIONS ATP2B1 gene polymorphism at rs2681472 shows significant differences between eclampsia patients and normal controls. Moreover, its gene polymorphism is closely related to the occurrence of hypertension and lower extremity edema.

Abstract
The overall goal of this study is to investigate the effect of sulfidated nanoscale zerovalent iron (S-nZVI) on the removal of hexavalent molybdate (MoO42-) under different aquatic chemistry conditions. Surface analysis suggests that Mo(VI) is removed mainly by adsorption and co-precipitation onto the surface of S-nZVI and a small amount of Mo(VI) can be reduced to Mo(V) species. The results of batch tests show that Mo(VI) removal by S-nZVI are well described with the pseudo-second-order adsorption model. The removal rate increases with a decrease in solution pH (4.0-9.0) and is significantly affected by the S/Fe ratio of S-nZVI, with the optimal S/Fe ratio being 0.5. The presence of anions WO42- or CrO42- can reduce the Mo(VI) removal, which is likely because they compete for adsorption sites on the solid surfaces. The divalent cations Ni2+, Cu2+ and Co2+ also inhibit the removal of Mo(VI) whereas Zn2+, Ca2+ and Mg2+ enhance it. After being aged for 35 d in water, S-nZVI still exhibits high reactivity towards Mo(VI) removal (57.39%). The study demonstrates that S-nZVI can be used as an environmentally friendly material for effectively removing Mo(VI) from contaminated water.

Abstract
OBJECTIVES Older adults with frailty are vulnerable to cardiovascular event and subsequent mortality. Frailty and albuminuria share atherosclerotic risk factors. The present study investigated the association of frailty and albuminuria among elderly Chinese inpatients. DESIGN Cross-sectional study. SETTINGS AND PARTICIPANTS A total of 202 patients aged over 60 years from the Center of Gerontology and Geriatric, West China Hospital. MEASUREMENTS Frailty was defined using the five-item FRAIL scale. This included measurements of fatigue, resistance, ambulation, illness, and loss of weight. We further determined the random urine albumin/creatinine ratio (UACR) of all patients. Random UACR ≥30 mg/g was defined as albuminuria, and < 30mg/g as normoalbuminuria. The relationship between albuminuria and frailty was assessed through multiple regression analysis. RESULTS The 202 participants (156 men, 77.2%) had an average age of 78.99±7.60 years, which ranged from 60 to 95. Compared to those without albuminuria, elderly patients with albuminuria were of an older age, had a higher prevalence of diabetes and poorer renal function. The prevalence of frailty, pre-frailty and ambulation (one of the FRAIL components) were higher in the albuminuria group than the normoalbuminuria group (23.9% vs. 12.2%, 47.9% vs.37.4%, 33.8% vs. 16.0%, respectively, P<0.05). Following the adjustment for age, eGFR, hypertension, diabetes and using ACEI/ARB, being frail or pre-frail led to an enhanced risk of albuminuria (OR frail 2.60, 95% CI frail 1.01-6.72; OR pre-frail 2.14, 95% CI pre-frail 1.03-4.44). CONCLUSIONS Frailty is independently associated with albuminuria when adjusted for classic cardiovascular risk factors.

Abstract
Dual-energy computed tomography (DECT) has shown a great potential for lowering range uncertainties, which is necessary for truly leveraging the Bragg peak in proton therapy. However, analytical stopping-power-ratio (SPR) estimation methods have limitations in resolving the influence from the beam-hardening artifact, i.e. CT number variation of the same object scanned under different imaging conditions, such as different patient size and location in the field-of-view (FOV). We present a convolutional neural network (CNN)-based framework to estimate proton SPR that accounts for patient geometry variation and addresses CT number variation. The proposed framework was tested on both prostate and head-and-neck (HN) patient datasets. Simulated CT images were used in order to have a well-defined ground-truth SPR for evaluation. Two training scenarios were evaluated: training with patient CT images (ideal scenario) and training with computational phantoms (realistic scenario). For the training in ideal scenario, computational phantoms were created based on 120 kVp patient CT images using a custom-defined density and material translation curve. Then, 80 kVp and 150 kVp Sn DECT image pairs were obtained using ray-tracing simulation, and their corresponding SPR was calculated from the known density and elemental compositions. For the training in realistic scenario, computational phantoms were created based on the geometry of calibration phantoms. For both scenarios, evaluation was performed on the phantoms created from patient CT images. Compared to a conventional parametric model, U-net trained with computational phantoms (realistic scenario) reduced the SPR estimation uncertainty (95th percentile) of the prostate patient from 1.10% to 0.71%, and HN patient from 2.11% to 1.20%. With the U-net trained with patient images (ideal scenario) uncertainty values were 0.32% and 0.42% for prostate and HN patients, respectively. These results suggest that CNN has great potential to improve the accuracy of SPR estimation in proton therapy by incorporating individual patient geometry information.

Abstract
AIMS To examine the association between 24 literature-based single nucleotide polymorphisms and diabetic kidney disease in Chinese people with type 2 diabetes. METHODS AND RESULTS Twenty-four candidate diabetic kidney disease-susceptible single nucleotide polymorphisms were genotyped in 208 participants with type 2 diabetes and diabetic kidney disease and 200 participants with type 2 diabetes without diabetic kidney disease (case and control groups, respectively), together with 206 healthy participants using MassARRAY. Rs11643718 in the SLC12A3 gene was associated with diabetic kidney disease in the recessive model after adjusting for confounding factors, such as age and gender (adjusted odds ratio 2.056, 95% CI 1.120-3.776; P = 0.020). Meta-analyses further confirmed the association (P = 0.002). In addition, participants with the GG genotype had worse renal function and more albuminuria than those with the AA+AG genotype (P < 0.05). Renal section immunohistochemistry was conducted in participants with type 2 diabetes, diabetic kidney disease and AA+AG or GG genotypes and in participants with glomerular minor lesions. Together with data from the Nephroseq database, it was shown that the abundance of SLC12A3 was reduced in patients with the GG genotype, while elevated expression of SLC12A3 was associated with better renal function. In addition, rs10951509 and rs1345365 in ELMO1, which were determined to be in high linkage disequilibrium by SHEsis software, were also associated with diabetic kidney disease (adjusted P = 0.010 and 0.015, respectively). CONCLUSIONS The G allele and GG genotype of SLC12A3 rs11643718 are associated with the development of diabetic kidney disease in a Chinese population with type 2 diabetes.

Abstract
OBJECTIVE Glioblastoma is identified as the most aggressive primary brain tumor. Growing evidence has demonstrated that aberrant expression of miR-191 has oncogenic potentiality in many cancers. However, the effects and the underlying mechanisms of miR-191 in the development of glioblastoma remain largely unknown. The aim of this study was to elucidate the pathobiological functions of miR-191 expression by targeting N-deacetylase/N-sulfotransferase 1 (NDST1) in human glioblastoma. PATIENTS AND METHODS The miR-191 level in human glioblastoma tissues and four cell lines was examined using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Animals study and MTT (3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay were used to examine the effects of miR-191 on human glioblastoma proliferation. Western blot and Luciferase reporter were used to confirm that miR-191 could regulate NDST1 expression. RESULTS We found that the miR-191 expression was upregulated in human glioblastoma tissues and cells. MiR-191 over-expression was sufficient to promote human glioblastoma cells growth in vivo and in vitro. We also found that miR-191 directly targeted NDST1 and negatively regulated the NDST1 expression in human glioblastoma cells. CONCLUSIONS In summary, our finding suggested that miR-191 acted as an important regulator in promoting glioblastoma cell proliferation in vivo and in vitro, and this cellular function may be because of its negative regulation of NDST1.

Abstract
OBJECTIVE To investigate the role of micro ribonucleic acid (miR)-181 in the inflammatory responses of osteoarthritis (OA) and related mechanism. MATERIALS AND METHODS The rat model of OA was established by anterior cruciate ligament (ACL) transection, and an automatic immuno-analyzer was applied to detect the bone metabolism indexes in the serum. The levels of relevant inflammatory factors in the joint fluid and serum were measured using enzyme-linked immunosorbent assay (ELISA). The cartilage specimens were collected to determine the expression of miR-181 in OA and normal cartilage tissues. Meanwhile, isolated cartilage cells were cultured and transfected with miR-181 mimics and inhibitor separately, and a blank control group was also included. Quantitative Real-time polymerase chain reaction (qRT-PCR) was adopted to detect the messenger RNA (mRNA) expressions of inflammatory factors [tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6)] in the cartilage cells. The expression levels of NF-κB and matrix metalloproteinase-13 (MMP-13) proteins related to the NF-κB signaling pathway were determined via Western blotting. RESULTS In OA model group, the content of serum osteocalcin (OSTEOC) and vitamin D (VD) declined markedly (p<0.05), the content of parathyroid hormone (PTH) increased notably (p<0.05), whereas the change of β-Cross Laps was not significant. ELISA results showed that the levels of TNF-α, IL-6 and MMP-9 were elevated remarkably in OA model group (p<0.05). Compared with that in normal cartilage tissues, miR-181 expression was increased evidently in OA cartilage tissues (p<0.05). Moreover, miR-181 expression was also significantly elevated in miR-181 mimics group after transfection (p<0.05). The expressions of inflammatory factors TNF-α and IL-6 in the cartilage cells were increased remarkably in miR-181 mimics group compared with those in control group (p<0.05). The miR-181 inhibitor could significantly lower the expressions of inflammatory factors TNF-α and IL-6 (p<0.05). According to the results of Western blotting, the protein expressions of MMP-13 and NF-κB were decreased notably in miR-181 inhibitor group (p<0.05), but were evidently up-regulated in miR-181 mimics group (p<0.05). CONCLUSIONS The decrease of miR-181 can reduce the expressions of inflammatory factors TNF-α and IL-6 through downregulating the NF-κB signaling pathway, thus repressing the occurrence of OA.

Abstract
OBJECTIVE The aim of this study was to examine the expression of circ-CCDC66 in gastric cancer (GC) tissues and cell lines, as well as its correlation with the prognosis of GC. Moreover, the regulatory effects of circ-CCDC66 on biological behaviors of GC cells and its molecular mechanism were explored. PATIENTS AND METHODS The relative expression level of circ-CCDC66 in GC tissues and cell lines was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlation between the circ-CCDC66 level and overall survival of GC patients was analyzed as well. The potential influences of circ-CCDC66 on proliferative and invasive abilities of GC cells were evaluated through 5-Ethynyl-2'-deoxyuridine (EdU), colony formation and transwell assay, respectively. Meanwhile, the cell cycle progression and apoptosis of GC cells affected by circ-CCDC66 were determined. In addition, the direct target miRNA of circ-CCDC66 was predicted and verified by bioinformatics method and Dual-Luciferase reporter gene assay, respectively. RESULTS Circ-CCDC66 was significantly up-regulated in GC tissues and cell lines. Up-regulation of circ-CCDC66 indicated markedly worse prognosis of GC patients. Transfection of circ-CCDC66-siRNA remarkably attenuated proliferative and invasive abilities of BGC-823 and MGC-803 cells. Besides, GC cells were arrested in the G0/G1 phase, and the apoptotic rate was remarkably elevated after circ-CCDC66 knockdown. The Dual-Luciferase reporter gene assay verified that circ-CCDC66 bind to miRNA-1238-3p by competing with LHX2 (LIM-homeobox domain 2). MiRNA-1238-3p was significantly down-regulated in GC cells, whereas LHX2 was up-regulated. Furthermore, overexpression of miRNA-1238-3p in GC cells markedly suppressed the LHX2 level. CONCLUSIONS Circ-CCDC66 is highly expressed in GC tissues and cell lines. Knockdown of circ-CCDC66 attenuates proliferative and invasive abilities of GC cells. Our results indicate that circ-CCDC66/miRNA-1238-3p/LHX2 axis may be a promising target for GC treatment.

Abstract
Objective: To understand the characteristics of HIV-1 genotypes and drug resistance among men who have sex with men in Kunming in 2018. Methods: A total of 193 plasma samples were collected from the newly reported HIV-1 infected MSM in Kunming from January to December 2018. Viral RNA was extracted, and the gag, pol, env gene segments were amplified by nested PCR. HIV-1 genotypes and drug resistance were also analyzed. Subsequently, the evolutionary characteristics of CRF55_01B and CRF68_01B among MSM in Kunming were analyzed by Bayesian Markov Chain Monte Carlo method. Results: Multiple HIV-1 genotypes were identified among these 193 samples, including CRF07_BC (39.4%, 76/193), CRF01_AE (34.2%, 66/193), unique recombinant forms (URFs) (20.2%, 39/193), CRF08_BC (3.1%, 6/193), CRF55_01B (1.6%, 3/193), subtype B (1.0%, 2/193) and CRF68_01B (0.5%, 1/193). Results from the Bayesian evolutionary analysis showed that CRF55_01B started to spread locally after being imported from other provinces, while CRF68_01B was likely to have been brought in from the eastern provinces of China. Prevalence of HIV-1 drug resistant strains was 2.6%(5/190) before antiviral treatment, with mutation rates resistant to non-nucleoside reverse transcriptase inhibitors being the highest (2.1%, 4/190) among MSM in Kunming, 2018. Conclusion: The diversity of HIV-1 was increasing among MSM in Kunming. Although the resistance rate on pretreatment drug was relatively low, the emergence of multiple resistant strains to first-line antiviral drugs posed a challenge to antiretroviral therapy, in Kunming.

Abstract
Objective: To understand the characteristics and differences of diarrhea-related symptoms caused by different pathogens, and the clinical features of various pathogens causing diarrhea. Methods: Etiology surveillance program was conducted among 20 provinces of China from 2010 to 2016. The acute diarrhea outpatients were collected from clinics or hospitals. A questionnaire was used to survey demographics and clinical features. VFeces samples were taken for laboratory detection of 22 common diarrhea pathogens, to detect and analyze the clinical symptom pattern characteristics of the patient's. Results: A total of 38 950 outpatients were enrolled from 20 provinces of China. The positive rates of Rotavirus and Norovirus were the highest among the five diarrhea-causing viruses (Rotavirus: 18.29%, Norovirus: 13.06%). In the isolation and culture of 17 diarrhea-causing bacterial, Escherichia coli showed the highest positive rates (6.25%). The clinical features of bacterial diarrhea and viral diarrhea were mainly reflected in the results of fecal traits and routine examination, but pathogenic Vibrio infection was similar to viral diarrhea. Conclusion: Infectious diarrhea presents different characteristics due to various symptoms which can provide a basis for clinical diagnosis.
