Abstract
Low intrinsic conductivity and large volume expansion seriously restrict the efficient lithium storage performance of metal sulfides. Here, we fabricate a hybrid material of NiS2 nanoparticles/carbon nanohelmets (NiS2/CNHs) to address the above issues. As an anode material in lithium-ion batteries, NiS2/CNHs exhibit excellent cycling stability (490 mA h g-1 after 3000 cycles at 5 A g-1) and rate properties (412 mA h g-1 at 10 A g-1), outperforming other NiS x -based anode materials. These remarkable performances originate from the three-dimensional helmet-like integrated architecture of NiS2/CNHs, which reduces the electrode resistance due to the tight combination between NiS2 and CNHs, provides efficient diffusion paths for the electrolyte and Li+ owing to the amorphous nanoporous carbon structure, and significantly mitigates the aggregation and buffers the large volumetric expansion of NiS2 nanoparticles upon long-term cycling thanks to the open three-dimensional architecture and well-dispersed NiS2 nanoparticles on it.

Abstract
Objective: To compare the cytogenetic and molecular responses, outcomes and severe hematologic toxicity of nilotinib and imatinib as frontline therapy in newly diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP) . Methods: Newly diagnosed CML-CP patients were consecutively recruited from January 2006 to December 2018 who received nilotinib and imatinib as first-line treatment. Clinical data were retrospectively analyzed. Results: A total of 524 patients were classified into 439 (83.8%) receiving imatinib and 85 (16.2%) receiving nilotinib. Comparing with imatinib group, patients in nilotinib group were much younger (P=0.019) and more with intermediate and high Sokal risks (P<0.001) , WBC ≥100×10(9)/L (P<0.001) , HGB<120 g/L (P<0.001) , blast cells in bone marrow (P=0.026) , splenomegaly (P<0.001) by physical examination at diagnosis, and longer interval from diagnosis to TKI treatment (P=0.003) . With a median TKI duration of 57 (range 3-153) months, the probabilities of complete cytogenetic response (CCyR) (P=0.011) , major molecular response (MMR) (P=0.001) and MR(4.5) (P=0.046) were much higher in nilotinib group than those in imatnib according to each risk group. There is no statistical significance on probabilities of failure free survival (FFS) , progression free survival (PFS) and overall survival (OS) at 6 years between the two groups. Multivariate analyses showed that imatinib was an adverse factor associated with achieving CCyR (OR=0.6, 95% CI 0.5-0.8, P=0.001) , MMR (OR=0.6, 95% CI 0.5-0.9, P=0.032) and MR(4.5) (OR=0.6, 95%CI 0.5-0.9, P=0.032) and poor FFS (OR=1.9, 95%CI 1.0-3.4, P=0.041) . In addition, Sokal score was an independent factor affecting cytogenetic and molecular responses, treatment failure, disease progression and survival. Male, WBC ≥100×10(9)/L or HGB<120 g/L at diagnosis were significantly associated with lower cytogenetic and molecular response rates and/or poor FFS. The severe hematologic adverse events were not associated with different TKIs. Conclusions: Nilotinib reaches to the faster and deeper cytogenetic and molecular responses and significantly improves FFS than imatinib in newly diagnosed patients with CML-CP.

Abstract
OBJECTIVE Diabetic nephropathy (DN), as the most common and serious diabetic microvascular complication, has become the first cause of end-stage renal disease (ESRD) in many countries and regions. However, the pathogenesis of renal fibrosis during the development of DN remains unknown. MATERIALS AND METHODS The expression levels of miR-192 and early growth response factor 1 (Egr1) were determined by quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) and Western blotting in the renal tissues of Otsuka-Long-Evans-Tokushima-Fatty (OLETF) and Long-Evans-Tokushima-Otsuka (LETO) rats. The diabetic kidney environment was simulated by a high-sugar medium. The expression levels of miR-192 and Egr1 were further measured in the HK-2 cell line. Egr1 was verified as a potential target of miR-192 by using bioinformatics analysis and luciferase activity assay. The expression level of Egr1 was determined by overexpressing and knocking down the expression of miR-192. In addition, Western blotting was used to determine changes in Transforming growth factor-beta 1 (TGF-β1) and fibronectin (FN). RESULTS Compared with the kidney tissue of LETO rats, the expression of miR-192 was decreased in OLETF rats, whereas the expression of Egr1 was increased. We found the same phenomenon in the HK-2 cell line cultured in the high-glucose medium. Next, miR-192 can act on Egr1 through 3'-UTR to reduce the expression of Egr1 verified by luciferase assay. In addition, the expression levels of TGF-β1 and FN changed significantly, as the expression level of Egr1 increased or decreased. CONCLUSIONS MiR-192 causes degradation of TGF-β1 and FN through targeting Egr1 and affects the progression of TIF and even DN.

Abstract
Objective: To investigate the characteristic and prognostic significance of leukemia stem cells associated antigens expressions including CD34, CD38, CD123, CD96 and TIM-3 in t (8;21) AML. Methods: Bone marrow samples of 47 t (8;21) AML patients were collected at diagnosis from October 2015 to April 2018 in Peking University Peoples' Hospital, then flow cytometry method was performed to detect the expression frequencies of CD34, CD38, CD123, CD96 and TIM-3 to analyze the relationship between leukemia stem cells associated antigens expressions and relapse. Results: Of 47 t (8;21) AML patients tested, the median percentages of CD34(+)CD38(-), CD34(+) CD38(-)CD123(+), CD34(+)CD38(-) CD96(+) and CD34(+) CD38(-) TIM-3(+) cells among nucleated cells were 2.37%, 0.24%, 0.27% and 0.06%, respectively. All the frequencies of CD34(+)CD38(-), CD34(+)CD38(-)CD123(+), CD34(+)CD38(-)CD96(+) and CD34(+) CD38(-)TIM-3(+) cells had no impact on the achievement of CR after the first course of induction. All higher frequencies of CD34(+)CD38(-), CD34(+)CD38(-)CD123(+), CD34(+)CD38(-)CD96(+) cells were related to higher 2-year CIR rate. Whereas, the frequency of CD34(+) CD38(-) TIM-3(+) cells had no impact on CIR rate. Both high frequency of CD34(+) CD38(-) cells and the high level of minimal residual diseases (patients with <3-log reduction in the RUNX1-RUNX1T1 transcript level after the second consolidation therapy) were independent poor prognostic factors of CIR[P=0.025, HR=6.9 (95%CI 1.3-37.4) ; P=0.031, HR=11.1 (95%CI 1.2-99.2) ]. Conclusion: Different leukemia stem cells associated antigens had distinct prognostic significance in t (8;21) AML. High frequencies of CD34(+) CD38(-), CD34(+) CD38(-) CD123(+) and CD34(+)CD38(-)CD96(+) cells at diagnosis predicted relapse in patients with t (8;21) AML.

Abstract
Lycium barbarum polysaccharides (LBP) are considered to be the major bioactive components of L. barbarum and have been widely used as a well-known traditional Chinese medicine and functional food because of their various biological activities. However, no published research has investigated the use of LBP as a feed additive in broilers. The objective of this study was to evaluate the effects of dietary LBP supplementation on the growth performance, digestive enzyme activities, antioxidant status, and immunity of broiler chickens. A total of 256 one-day-old Arbor Acres male broiler chicks were randomly allotted into 4 groups, with 8 replicates of 8 birds each, and were fed a corn-soybean meal-type basal diet supplemented without (control group) or with 1,000, 2,000, or 4,000 mg/kg LBP for 6 wk. The results showed that compared with the control diet, a significant increase in ADG (P < 0.05) during the grower and overall periods was observed in chickens fed the basal diet supplemented with 2,000 mg/kg LBP, whereas supplementation with 1,000 or 2,000 mg/kg LBP decreased feed-to-gain ratio (P < 0.05) during the starter period. The inclusion of LBP in the broiler diets increased overall amylase, lipase, and protease activities (P < 0.05). Supplementation with increasing levels of dietary LBP increased the activities of superoxide dismutase and glutathione peroxidase but decreased malondialdehyde content in the serum and liver (P < 0.05). Broilers fed with LBP-containing diets exhibited higher serum IgG and IgA concentrations (P < 0.05) than the broilers fed with the control diet. Serum tumor necrosis factor α and IL-4 concentrations were significantly elevated in the group fed 2,000 mg/kg LBP compared with the control group (P < 0.05). Broilers fed diets supplemented with LBP showed linear (P < 0.05) and quadratic (P < 0.05) increases in serum IL-6 and interferon gamma concentrations. The results indicated that dietary LBP supplementation can improve growth performance, digestive enzyme activities, antioxidant capacity, and immune function of broilers. In conclusion, LBP may be used as a promising feed additive for broilers, and a supplementation level of 2,000 mg/kg LBP in the broiler diet is recommended.

Abstract
OBJECTIVE To investigate whether CD31 could regulate paracetamol-induced liver injury, thereby providing a new direction for the prevention and treatment of drug-induced hepatitis. MATERIALS AND METHODS Wild-type (WT) mice were treated with acetaminophen (APAP) (250 mg/kg) or isodose of phosphate-buffered saline (PBS). 1, 3, 6 and 12 h after the treatment, the messenger RNA (mRNA) and protein expression level of CD31 in the liver of mice were determined by Real-time reverse transcription polymerase chain reaction (RT-PCR) and Western blotting, respectively. Once CD31 was confirmed to be involved in APAP-induced liver injury, the acute liver injury model in WT mice and CD31 gene deficient (CD31-/-) mice induced by APAP was established. Serum samples were collected at 8 and 24 h after APAP injection (250 mg/kg), and the activity of serum alanine aminotransferase (ALT) was measured. The liver tissues of mice were isolated and analyzed by hematoxylin and eosin (HE) staining. Meanwhile, mononuclear cells (MNCs) were isolated from the liver tissues of mice. The number of infiltrating macrophages and neutrophils was detected by flow cytometry, and the activation level of these cells was analyzed. The expression levels of proinflammatory cytokines in liver tissues, such as TNF-α, IL-1β, keratinocyte chemoattractant (KC), MCP-1 and IL-6, were determined by RT-PCR. The expression levels of cytokines in serum were detected by enzyme-linked immunosorbent assay (ELISA). Moreover, the protein expression levels of JNK, Caspase-3, and cytochrome P450 2E1 (CYP2E1) in liver tissues were detected by Western blotting. RESULTS After APAP treatment, we found that WT mice were more sensitive to APAP-induced liver injury. The level of ALT in WT mice was significantly higher than that of CD31-/- mice, meanwhile, more necrotic or apoptotic cells were found in WT mice. Results also indicated that the expression levels of inflammatory cytokines, including KC, IL-1β, MCP-1 and IL-6, were significantly higher in WT mice. Meanwhile, the number of infiltrating macrophages and neutrophils in the liver tissues of WT mice were much more than that of CD31-/- mice. CONCLUSIONS APAP-treated CD31-/- mice exhibited less liver injury when compared with WT mice. We also confirmed that CD31 was greatly involved in APAP-induced inflammatory response by promoting hepatic inflammatory and cell apoptosis, which might provide a new strategy for the prevention and treatment of drug-induced hepatitis.

Abstract
We have explored the relations between clinicopathological features and cervical lymph node metastases (LNM) in patients with cN0 squamous cell carcinoma (SCC) of the tongue, and developed and validated a nomogram for predicting the risk of their development. Clinical data on 230 patients with cN0 SCC of the tongue who had had primary extended excision and lymph node dissection of the neck were collected retrospectively. They were divided into a development cohort and a validation cohort in a 4:1 ratio. Logistic regression analysis was used to assess the risk factors of cervical LNM in patients in the development cohort, and a nomogram was established to predict the risk of such nodes. In the validation cohort, the predictive performance and compliance of the model were evaluated using the consistency index (C-index) and calibration curve, and the clinical value was evaluated by decision curve analysis. Of the 230 patients, 60 had cervical LNM, of which 60 were invaded (26%). Analysis of the development cohort showed that the site of the primary lesion, depth of invasion, size of the tumour, and histopathological grade were included in the prediction model, which was validated in the validation cohort. Consistency was high (C-index=0.846), calibration good, and it was clinically valuable. The nomogram could be used to predict the probability of occult cervical LNM before operation in patients with stage cN0 SCC of the tongue. It could also be used as a reference tool for dissection of cervical nodes and a communication tool between the doctor and the patient.

Abstract
Clostridium perfringens is the main cause of sudden death in dogs and currently there is no vaccine to prevent it. In this study, a canine C. perfringens type A strain was used to prepare a vaccine. C. perfringens was inactivated by formaldehyde and adjuvants were added. The safety and immunological characteristics of the inactivated C. perfringens vaccine were evaluated in mice and dogs. The results showed that the C. perfringens vaccine was safe and had immunoprotective activity. The serum antibody titre of immunized mice reached up to 6·25 × 104 . Both single immunization of 4 ml and dual immunizations of 2 ml each provided good immune protection, with five of five immunized dogs surviving. This study also studied a detoxified crude α-toxin extract vaccine. The results showed that a single immunization with 0·5 ml of the detoxified crude α-toxin extract vaccine provided immune protection, with five of five immunized dogs surviving. The inactivated C. perfringens type A vaccine can be used to prevent canine C. perfringens infections. SIGNIFICANCE AND IMPACT OF THE STUDY: Clostridium perfringens is the main cause of sudden death in dogs and currently there is no vaccine to prevent it. In this study, an inactivated canine C. perfringens vaccine and a detoxified crude α-toxin vaccine were prepared. The safety and protective effects of these vaccines were evaluated using mouse and dog models. The vaccines were shown to be safe and to provide immune protection effects that can be used to prevent canine C. perfringens infection.

Abstract
Fibroblast growth factor receptor 2 ( FGFR2) in craniofacial bones mediates osteoprogenitor proliferation, differentiation, and apoptosis. The distortion of proper craniofacial bone growth may cause class II and class III skeletal malocclusion and result in compromised function and aesthetics. Here, we investigated the association between variations in FGFR2 and skeletal malocclusions. First, 895 subjects were included in a 2-stage case-control study with independent populations (stage 1: n = 138 class I, 111 class II, and 81 class III; stage 2: n = 279 class I, 187 class II, and 99 class III). Eight candidate single-nucleotide polymorphisms (SNPs) in FGFR2 were screened and validated. Five SNPs (rs2162540, rs2981578, rs1078806, rs11200014, and rs10736303) were found to be associated with skeletal malocclusions (all P < 0.05). That is, rs2162540 was significantly associated with skeletal class II malocclusion, while others were associated with skeletal class III malocclusion. Electrophoretic mobility shift assay and chromatin immunoprecipitation analysis showed that the common genotypes of rs2981578 and rs10736303 contained the binding sites of RUNX2 and SMAD4. Compared with the common genotypes, the minor genotypes at these 2 SNPs decreased the binding affinity and enhancer effect of RUNX2 and SMAD4, as well the levels of FGFR2 expression. In addition, FGFR2 expression contributed positively to osteogenic differentiation in vitro. Thus, we identified FGFR2 as a skeletal malocclusion risk gene, and FGFR2 polymorphisms regulated its transcriptional expression and then osteogenic differentiation.

Abstract
Oxidative stress (OS) is one of the responsible factors for causing renal diseases. For the treatment or prevention of the renal disease, antioxidants use could be a hopeful therapeutic mediation as they block the oxidative reaction along with inflammatory process. Wogonin (Wog) is a plant flavonoid, a pharmacologically active component of Scutellaria baicalensis Georgi (Huang Qui), which exhibits antioxidant activity. In this investigation, we explored the nephroprotective activity of Wog on cadmium (Cd)-induced nephron toxicity in rats. Administering (10 and 20 mg/kg) intraperitoneally diminished Cd-induced anomalies in kidney histology and creatinine and serum urea levels. Wog therapy reduced the Cd-influenced generation of inflammatory mediators, inclusive of tumor necrosis factor alpha, interleukin 6, and interleukin 1 beta. Western blot analysis demonstrated that Wog abolished proinflammatory nuclear factor-kappa B (NF-κB) p65 stimulation, phosphorylation of p38 mitogen-activated protein kinases (MAPKs). In all, Wog demonstrated antioxidative and anti-inflammatory effects in Cd- intoxicated rats by obstructing OS and activation of NF-κB via restricting the stimulation of upstream kinases inclusive of MAPKs.

Objective: To compare the clinical features between the 2 cohorts developing myelodysplastic syndrome or acute myeIogenous Ieukemia in Philadelphia chromosome-negative cells (Ph(-) MDS/AML) and maintaining disease stable in the patients with Philadelphia chromosome-positive chronic myeloid Ieukemia (Ph(+) CML) who had clonal chromosomal abnormalities in Philadelphia chromosome-negative metaphases (CCA/Ph(-)) during tyrosine kinase inhibtor (TKI) - therapy. Methods: We retrospectively analyzed Ph(+) CML patients who developed CCA/Ph(-) during TKI-therapy from May 2001 to December 2017. Results: Data of CCA/Ph(-) 63 patients, including 7 progressing to Ph(-) MDS/AML and 56 remaining disease stable were collected. Compared with those with stable disease, patients with Ph(-)MDS/AML had lower hemoglobin (P=0.007) and platelet (P=0.006) counts, and higher proportion of peripheral blasts (P<0.001) when the first time CCA/Ph(-) was detected, and more mosonomy 7 abnormality (5/7, 71.4%) when MDS or AML was diagnosed; meanwhile, trisomy 8 (32/56, 57.1%) was more common in those with stable disease. Outcome of the patients with Ph(-) MDS/AML were poor. However, most of those with CCA/Ph(-) and stable disease had optimal response on TKI-therapy. Conclusions: A few patients with Ph(+) CML developed CCA/Ph(-) during TKI-therapy, most of them had stable disease, but very few patients developed Ph(-) MDS/AML with more common occurrence of monosomy 7 or unknown cytopenia. Our data suggested the significance of monitoring of peripheral blood smear, bone marrow morphology and cytogenetic analysis once monosomy 7 or unknown cytopenia occurred.

Abstract
Objective: To investigate the efficacy and prognostic factors of induction therapy in FLT3-ITD(+) acute myeloid leukemia (AML) in the real world data. Methods: From January 2013 to December 2016, 114 de novo patients with FLT3-ITD(+)AML were enrolled in this study. Out of 114 cases, 75 were male, and 39 were female. The median age was 42 years old (ranged from 14 to 72 years old) . The chemotherapy regimens were used for induction therapy and all cases were followed up. The treatment response was evaluated by MICM and the comparison of the ratio were analyzed by chi-square test and the survival was estimated by Kaplan-Meier analysis and Cox proportional hazards model was used to identify independent prognostic factors. Results: There were 52 FLT3-ITD(+)AML patients with favorable prognosis genes (46 cases with NPM1, 5 cases with RUNX1-RUNX1T1, 1 case with CEBPA double mutation) and 62 patients with other types of FLT3-ITD(+)AML at diagnosis. All patients completed at least one cycle of induction therapy and the clinical curative effect was evaluated, complete remission (CR) rate was 50.0% (57/114) in one cycle and total CR rate was 72.5% (74/104) in two cycles. The CR rate of the FLT3-ITD(+) AML patients with favorable prognosis genes was 67.3% (35/52) in one cycle and 83.3% (40/48) in two cycles; for the other types FLT3-ITD(+)AML patients, the CR rate was 35.5% (22/62) in one cycle and 64.8% (35/54) in two cycles. There was a significant difference in CR rate between the FLT3-ITD(+)AML patients with and without favorable prognosis genes (P<0.05) . This indicates that the FLT3-ITD(+)AML patients with favorable prognosis gene had relatively good therapeutic effect. Among other types of FLT3-ITD(+)AML patients who did not achieve remission from one cycle of chemotherapy, 9 patients were given sorafenib plus chemotherapy and 6 cases (66.7%) achieved CR; 23 patients were given conventional chemotherapy and 7 cases (30.4%) achieved CR. There was a significant difference between sorafenib plus chemotherapy and conventional chemotherapy groups (χ(2)=4.47, P<0.05) and this indicates that sorafenib plus chemotherapy can significantly improve the CR rate of FLT3-ITD(+)AML patients. Comparing overall survival (OS) and disease free survival (DFS) , there was no significant difference between sorafenib plus chemotherapy and conventional chemotherapy groups (P values were 0.641 and 0.517, respectively) . Conclusion: The overall prognosis of FLT3-ITD(+)AML patients is poor, and the stratification therapeutic efficacy of FLT3-ITD(+)AML without favorable prognosis gene can be improved by sorafenib combined with chemotherapy.

Abstract
Minimally invasive devices to detect molecules in dermal interstitial fluid (ISF) are desirable for point-of-care diagnostic and monitoring applications. In this study, we developed a microneedle (MN) patch that collects ISF for on-patch biomarker analysis by surface-enhanced Raman scattering (SERS). The micrometer-scale MNs create micropores in the skin surface, through which microliter quantities of ISF are collected onto plasmonic paper on the patch backing. The plasmonic paper was prepared by immobilizing poly(styrenesulfonate) (PSS) coated gold nanorods (AuNRs) on a thin strip of filter paper using plasmonic calligraphy. Negatively charged PSS was used to bind positively charged rhodamine 6G (R6G), which served as a model compound, and thereby localize R6G on AuNR surface. R6G bound on the AuNR surface was detected and quantified by acquiring SERS spectra from the plasmonic paper MN patch. This approach was used to measure pharmacokinetic profiles of R6G in ISF and serum from rats in vivo. This proof-of-concept study indicates that a plasmonic paper MN patch has the potential to enable on-patch measurement of molecules in ISF for research and future medical applications.

Abstract
The study aimed to identify the pivotal genes and pathways involved in prostate cancer metastasis. Using the expression profile dataset GSE7930, downloaded from the Gene Expression Omnibus (GEO) database, differentially expressed genes (DEGs) between primary and highly metastatic prostate cell samples were screened, followed by functional analysis and tumor associated genes (TAG) screening. Protein-protein interaction (PPI) network of DEGs was constructed and module analysis was performed. The expression of DEGs and pathway related genes were evaluated by PCR analysis and the migra- tion ability of prostate tumor cells was observed after FABP4-siRNA blocking. Upregulated FABP4 and GK were signifi- cantly enriched in the PPAR signaling pathway, whereas downregulated IGFBP3 and THBS1 were involved in p53 signaling pathway. Among the identified DEGs, 4 downregulated genes (IGFBP3, NPP4B, THBS1, and PCDH1) and 2 upregulated genes (GJA1 and TUSC3) were TAGs. The module was associated with focal adhesion, ECM-receptor interaction, p53 signaling, and gap junction pathways with the hub node GJA1. After FABP4 silencing by siRNAs in LNcap and metastatic DU-145 cells, the numbers of migrated cells were all significantly declined. The expressions of IGFBP3, TP53 and PPAR were significantly lower in DU-145 cells than in LNcap cells. In conclusion, FABP4, IGFBP3, THBS1, and GJA1 were determined to be potential markers of prostate cancer cell metastasis, and P53, PPAR and gap junction pathways were found to play important roles in prostate cancer cell metastasis. This study may provide helpful guidelines for clinical management.

Abstract
<sec> <title>SETTING</title> The proportion of bacteriologically confirmed tuberculosis (TB) in China has decreased far below the worldwide average. </sec> <sec> <title>OBJECTIVE</title> To investigate whether stepwise measures to ensure sputum quality can improve the rate of bacteriologically confirmed TB. </sec> <sec> <title>DESIGN</title> We enrolled 980 adults with suspected TB from three counties in China during 2017 for this multicentre randomised controlled trial. Half the participants (n = 490) were randomly assigned to intervention groups that received instructions by a study nurse, and sputum induction, if necessary. In the remaining 490 patients, sputum samples were collected without observation. The primary outcome was the proportion of patients detected as bacteriologically positive on smear, culture or molecular assays (EasyNAT or Xpert). </sec> <sec> <title>RESULTS</title> Bacteriological confirmation rates were significantly higher in the intervention than in the control group: overall (159/490 [32%] vs. 122/490 [25%]; P = 0.009); confirmation using smear (17% vs. 11%; P = 0.010); confirmation using culture (28% vs. 21%; P = 0.021); and confirmation using molecular assays (27% vs. 18%; P = 0.001). Most of the improvement was in patients who received instruction alone, while improvement was greatest in younger patients (adjusted odds ratio 1.27, 95%CI 1.05-1.53 per 10 years). </sec> <sec> <title>CONCLUSIONS</title> If implemented effectively in resource-limited primary care clinics, our simple stepwise procedure combining instruction and sputum induction could increase the proportion of bacteriologically confirmed TB significantly. </sec>.
