Abstract
Valley is used as a new degree of freedom for information encoding and storage. In this work, the valley and topological properties of the VSiGeP4 monolayer were studied by adjusting the U value based on first-principles calculations. The VSiGeP4 monolayer remains in a ferromagnetic ground state regardless of the change in the U value. The magnetic anisotropy of the VSiGeP4 monolayer is initially in-plane, and then turns out-of-plane with the increase in the U value. Moreover, a topological phase transition is observed in the present VSiGeP4 monolayer with the increase in U value from 0 to 3 eV, i.e., the VSiGeP4 monolayer behaves as a bipolar magnetic semiconductor, a ferrovalley semiconductor, a half-valley metal characteristic, and a quantum anomalous Hall state. The mechanism of the topological phase transition behavior of the VSiGeP4 monolayer was analyzed. It was found that the variation in U values would change the strength of the electronic correlation effect, resulting in the valley and topological properties. In addition, carrier doping was studied to design a valleytronic device using this VSiGeP4 monolayer. By doping 0.05 electrons per f.u., the VSiGeP4 monolayer with a U value of 3 eV exhibits 100% spin polarization. This study indicates that the VSiGeP4 monolayer has potential applications in spintronic, valleytronic, and topological electronic nanodevices.

Abstract
Costimulatory and co-inhibitory receptors on T lymphocytes play an essential role in the immune response. There is increasing evidence that the expression of co-signal molecules on T cells is altered in infection, tumor, autoimmunity, and other diseases, and that intervention of co-signal molecules can be used in the immunotherapy. This paper reviewed the costimulatory and coinhibitory receptors on Mtb-specific T lymphocytes and further explained the mechanism of co-signal molecules in the progression of tuberculosis, to provide a reference for future research and clinical application.

Abstract
Objective: To understand the prevalence of occasional hypertension in preschool children in three provinces in the middle and lower reaches of the Yangtze River in China, and analyze the relationship between their sleep status and occasional hypertension. Methods: From October to November 2017, a total of 24 842 preschool children from 109 kindergartens in 11 cities in Hubei, Anhui and Jiangsu provinces were selected by intentional sampling method. A self-made questionnaire was used to collect basic information about the subjects, and the sleep status data was collected by the Children's Sleep Habits Questionnaire. Physical examinations were performed on the subjects, and height, weight and blood pressure were measured on-site. The difference in occasional hypertension detection rate among preschool children with different characteristics was compared, and the correlation between sleep status and occasional hypertension detection rate was analyzed by the multivariate logistic regression model. Results: The age of the subjects was (4.4±1.0) years, including 12 729 boys (51.2%). The prevalence of occasional hypertension was 31.8% (7 907/24 842). The prevalence of occasional hypertension among preschool children in three provinces of the middle and lower reaches of the Yangtze River was 31.8%. There were statistically significant differences in the detection rate of occasional hypertension among preschool children of different genders, age groups, family residence, family economic status and parents' education level (all P values<0.05). The detection rate of occasional hypertension in children with less than 10 hours of sleep was higher than those with sufficient sleep, and the difference was statistically significant (P<0.05). The results of multivariate logistic regression analysis showed that after adjusting for factors such as gender, age, family residence, family economic status, parental education level, parental smoking history, and physical constitution, the ORs (95%CI) for less than 10 hours of sleep, turning on the lights while sleeping, and poor sleep quality were 1.09 (1.03-1.15), 1.17 (1.07-1.28) and 1.04 (0.91-1.18), respectively, compared with the corresponding reference group. Conclusion: The detection rate of occasional hypertension is high in preschool children in the middle and lower reaches of the Yangtze River and there is a positive correlation between insufficient sleep and turning on the light when sleeping and occasional hypertension in preschool children.

Abstract
The behavioral problems of children and adolescents are becoming more and more serious, and the prevalence rate is increasing year by year. The overall trend is increasing, which has become one of the important public health issues of global concern. There are many influencing factors for behavioral problems in children and adolescents, including genetic, psychosocial, family and early life environment. Among them, maternal screen exposure during pregnancy is a contributing factor that deserves attention and has practical intervention significance. This study systematically evaluated the association between maternal mobile phone screen time during pregnancy and children's internalizing and externalizing behavioral problems, its potential biological mechanisms and relevant intervention measures, in order to create a good intrauterine environment for fetal neurodevelopment and further reduce the occurrence of children's behavioral problems.

Abstract
Fatty acid metabolism reprogramming is a prominent feature of clear cell renal cell carcinoma (ccRCC). Increased lipid storage supports ccRCC progression, highlighting the importance of understanding the molecular mechanisms driving altered fatty acid synthesis in tumors. Here, we identified that malonyl-CoA decarboxylase (MLYCD), a key regulator of fatty acid anabolism, was downregulated in ccRCC, and low expression correlated with poor prognosis in patients. Restoring MLYCD expression in ccRCC cells decreased the content of malonyl CoA, which blocked de novo fatty acid synthesis and promoted fatty acid translocation into mitochondria for oxidation. Inhibition of lipid droplet accumulation induced by MLYCD-mediated fatty acid oxidation disrupted endoplasmic reticulum and mitochondrial homeostasis, increased reactive oxygen species levels, and induced ferroptosis. Moreover, overexpressing MLYCD reduced tumor growth and reversed resistance to sunitinib in vitro and in vivo. Mechanistically, HIF2α inhibited MLYCD translation by upregulating expression of eIF4G3 microexons. Together, this study demonstrates that fatty acid catabolism mediated by MLYCD disrupts lipid homeostasis to repress ccRCC progression. Activating MLYCD-mediated fatty acid metabolism could be a promising therapeutic strategy for treating ccRCC. SIGNIFICANCE MLYCD deficiency facilitates fatty acid synthesis and lipid droplet accumulation to drive progression of renal cell carcinoma, indicating inducing MYLCD as a potential approach to reprogram fatty acid metabolism in kidney cancer.

Abstract
Recent experiments demonstrated that proton transport through graphene electrodes can be accelerated by over an order of magnitude with low intensity illumination. Here we show that this photo-effect can be suppressed for a tuneable fraction of the infra-red spectrum by applying a voltage bias. Using photocurrent measurements and Raman spectroscopy, we show that such fraction can be selected by tuning the Fermi energy of electrons in graphene with a bias, a phenomenon controlled by Pauli blocking of photo-excited electrons. These findings demonstrate a dependence between graphene's electronic and proton transport properties and provide fundamental insights into molecularly thin electrode-electrolyte interfaces and their interaction with light.

Abstract
It has long been expected that the coexistence of ferroelectric and ferrovalley polarizations in one magnetic semiconductor could offer the possibility to revolutionize electronic devices. In this study, monolayer and bilayer YI2 are studied. Monolayer YI2 is a ferromagnetic semiconductor and exhibits a valley polarization up to 105 meV. All of the present bilayer YI2 regardless of stacking orders show antiferromagnetic states. Interestingly, the bilayer YI2 with 3R-type stackings shows not only valley polarization but also unexpected ferroelectric polarization, proving the concurrent ferrovalley and multiferroics behaviors. Moreover, the valley polarization of 3R-type bilayer YI2 can be reversed by controlling the direction of ferroelectric polarization through an electric field or manipulating the magnetization direction using an external magnetic field. The amazing phenomenon is also demonstrated in 2D van der Waals LaI2 and GdBr2 bilayers. A design idea of multifunctional devices is proposed based on the concurrent ferrovalley and multiferroics characteristics.

Abstract
PURPOSE To investigate the differences in higher-order aberrations between non-toric or toric implantable collamer lens (ICL or TICL) V4c implantation and simulated spectacle correction. METHODS Patients with high myopia who underwent ICL/TICL V4c implantation were enrolled. The "total no defocus" pattern of iTrace aberrometry to simulate the condition of spectacle correction was measured before ICL/TICL implantation, and higher-order aberrations in this condition were compared to those 3 months after surgery. Related factors with changes in coma were comprehensively analyzed. RESULTS A total of 89 right eyes of 89 patients were included. Compared to simulated spectacle correction, total-eye coma (P<0.0001 ICL, P<0.0001 TICL) and internal coma (P<0.0001 ICL, P<0.001 TICL) decreased in the ICL- and TICL-treated groups after surgery. Total-eye secondary astigmatism (P<0.0001 ICL, P=0.007 TICL) and internal secondary astigmatism (P<0.0001 ICL, P=0.009 TICL) were also decreased in both groups postoperatively. Spherical error showed positive correlations with variation in total-eye coma (r=0.37, P=0.004 ICL; r=0.56, P=0.001 TICL) and internal coma (r=0.30, P=0.02 ICL and r=0.45, P=0.01 TICL). Axial length revealed negative correlations with changes in total-eye coma (r=-0.45, P<0.001 ICL; r=-0.39, P=0.03 TICL) and internal coma (r=-0.28, P=0.03 ICL and r=-0.42, P=0.02 TICL). CONCLUSIONS Both ICL- and TICL-treated groups demonstrated a decrease in coma and secondary astigmatism after 3 months, postoperatively. ICL/TICL may confer a compensatory effect on coma aberration and secondary astigmatism. Patients with a higher myopia achieved a greater improvement in coma and may benefit more from ICL/TICL implantation than from spectacle correction implantation than from spectacle correction.

Abstract
Two-dimensional ferrovalley materials should simultaneously possess three characteristics, that is, a Curie temperature beyond atmospheric temperature, perpendicular magnetic anisotropy, and large valley polarization for potential commercial applications. In this report, we predict two ferrovalley Janus RuClX (X = F, Br) monolayers by first-principles calculations and Monte Carlo simulations. The RuClF monolayer exhibited a valley-splitting energy as large as 194 meV, perpendicular magnetic anisotropy energy of 187 μeV per f.u., and Curie temperature of 320 K. Thus, spontaneous valley polarization at room temperature will be present in the RuClF monolayer, which is nonvolatile for spintronic and valleytronic devices. Although the valley-splitting energy of the RuClBr monolayer was as high as 226 meV with magnetic anisotropy energy of 1.852 meV per f.u., the magnetic anisotropy of the RuClBr monolayer was in-plane, and its Curie temperature was only 179 K. The orbital-resolved magnetic anisotropy energy revealed that the interaction between the occupied spin-up states of dyz and the unoccupied spin-down states of dz2 dominated the out-of-plane magnetic anisotropy in the RuClF monolayer, but the in-plane magnetic anisotropy of the RuClBr monolayer was mostly contributed by the coupling of the dxy and dx2-y2 orbitals. Interestingly, the valley polarizations in the Janus RuClF and RuClBr monolayers appeared in their valence band and conduction band, respectively. Thus, two anomalous valley Hall devices are proposed using the present Janus RuClF and RuClBr monolayers with hole and electron doping, respectively. This study provides interesting and alternative candidate materials for the development of valleytronic devices.

Abstract
Two-dimensional (2D) nanomaterials hold great potential for cancer theranostic applications, yet their clinical translation faces great challenges of high toxicity and limited therapeutic/diagnostic modality. Here, we have created a kind of symbiotic 2D carbon-2D clay nanohybrids, which are composed of a novel 2D carbon nanomaterial (carbon nanochips, or CNC), prepared by carbonizing a conjugated polymer polydiiodobutadiyne, and a 2D layered aluminosilicate clay mineral montmorillonite (MMT). Intriguingly, with the formation of the nanohybrids, MMT can help the dispersion of CNC, while CNC can significantly reduce the hemolysis and toxicity of MMT. The symbiotic combination of CNC and MMT also leads to a synergistic anti-cancer theranostic effect. CNC has a strong absorption and high photothermal conversion efficiency in the second near-infrared region (NIR-II, 1000-1700 nm), while MMT contains Fe3+ that can facilitate the generation of reactive oxygen species from highly expressed H2O2 in tumor microenvironment. The nanohybrids not only enable a synergy of photothermal therapy and chemodynamic therapy to suppress the extremely rapid growth of RM1 tumors in mice but also allow for dual photoacoustic and magnetic imaging to guide the drug delivery and NIR-II irradiation execution, hence establishing a highly efficient and biosafe "all-in-one" theranostic platform for precision nanomedicine.

Abstract
Statins are prescribed widely as lipid-lowering agents. However, statins are associated with an increased harmful risk on public health and the ecosystem. Little is known about statins' toxicity on biological development and the underlying molecular mechanisms. We exposed zebrafish embryos to a series of statins to evaluate their development toxicity. Statins-induced embryonic developmental defects in a concentration-dependent manner. 72 h LC50 values for lovastatin, simvastatin, fluvastatin, atorvastatin, rosuvastatin, and pravastatin were 0.01 μM, 0.04 μM, 1.93 μM, 37.28 μM, 79.29 μM, and 2170 μM, respectively. Moreover, the expression of genes involved in heart contraction, calcium ion binding, transcription factors, nucleus, and G protein-coupled receptor signaling pathway was altered by statins. The early growth response gene (egr4) and transcription factor genes (fosab and fosb) were screened as potential toxicity targets due to their significant upregulation based on protein-protein interaction (PPI) and drug-gene interaction network analysis. Finally, the ecotoxicity profile of statins was predicted by in silico method, and statins were high or moderate risk to aquatic organisms. We provide a systems toxicology strategy to explore the toxicity of statins and illustrate the potential mechanisms of action.

Abstract
OBJECTIVE The purpose of this study was to determine whether xenon post-conditioning affects mTOR signaling as well as endoplasmic reticulum stress (ERS)-apoptosis pathway in rats with spinal cord ischemia/reperfusion injury. METHODS Fifty male rats were randomized equally into sham-operated group (Sham group), I/R model group (I/R group), I/R model+ xenon post-conditioning group (Xe group), I/R model+rapamycin (a mTOR signaling pathway inhibitor) treatment group (I/R+ Rapa group), and I/R model + xenon post- conditioning with rapamycin treatment group (Xe + Rapa group).. In the latter 4 groups, SCIRI was induced by clamping the abdominal aorta for 85 min followed by reperfusion for 4 h. Rapamycin (or vehicle) was administered by daily intraperitoneal injection (4 mg/kg) for 3 days before SCIRI, and xenon post-conditioning by inhalation of 1∶1 mixture of xenon and oxygen for 1 h at 1 h after initiation of reperfusion; the rats without xenon post-conditioning were given inhalation of nitrogen and oxygen (1∶ 1). After the reperfusion, motor function and histopathologic changes in the rats were examined. Western blotting and real-time PCR were used to detect the protein and mRNA expressions of GRP78, ATF6, IRE1α, PERK, mTOR, p-mTOR, Bax, Bcl-2 and caspase-3 in the spinal cord. RESULTS The rats showed significantly lowered hind limb motor function following SCIRI (P < 0.01) with a decreased count of normal neurons, increased mRNA and protein expressions of GRP78, ATF6, IRE1α, PERK, and caspase-3, and elevated p-mTOR/mTOR ratio and Bax/Bcl-2 ratio (P < 0.01). Xenon post-conditioning significantly decreased the mRNA and protein levels of GRP78, ATF6, IRE1α, PERK and caspase-3 (P < 0.05 or 0.01) and reduced p-mTOR/mTOR and Bax/Bcl-2 ratios (P < 0.01) in rats with SCIRI; the mRNA contents and protein levels of GRP78 and ATF6 were significantly decreased in I/R+Rapa group (P < 0.01). Compared with those in Xe group, the rats in I/R+Rapa group and Xe+Rapa had significantly lowered BBB and Tarlov scores of the hind legs (P < 0.01), and caspase-3 protein level and Bax/Bcl-2 ratio were significantly lowered in Xe+Rapa group (P < 0.05 or 0.01). CONCLUSION By inhibiting ERS and neuronal apoptosis, xenon post- conditioning may have protective effects against SCIRI in rats. The mTOR signaling pathway is partially involved in this process.

Abstract
Alcoholic hepatitis is a severe and life-threatening systemic inflammatory response syndrome, which has a high incidence and mortality rate worldwide. The severity ranges from asymptomatic liver biochemical disturbances to fulminant liver failure or death; however, there are few effective therapeutic interventions. Maddrey discriminant function not only predicts short-term mortality, but it also guides clinicians to choose appropriate alcoholic hepatitis-specific treatments. Alcohol abstinence, nutritional support, psychological counseling, and infection prevention remain the cornerstones for alcoholic hepatitis treatment. Corticosteroids remain the mainstay of treatment when patients have a good appetite and normal serum creatinine levels, but early liver transplantation is the only life-saving option for steroid-unresponsive patients. New studies have found that gut microbiota is an important therapeutic targets in patients with alcohol hepatitis, and N-acetylcysteine, granulocyte colony-stimulating factor, and metadoxine as adjunctive therapy have a positive effect on patient survival.

Abstract
Supplying wireless power is a challenging technical problem of great importance for implantable biomedical devices. Here, we introduce a novel implantable piezoelectric ultrasound energy-harvesting device based on Sm-doped Pb(Mg1/3Nb2/3)O3-PbTiO3 (Sm-PMN-PT) single crystal. The output power density of this device can reach up to 1.1 W/cm2 in vitro, which is 18 times higher than the previous record (60 mW/cm2). After being implanted in the rat brain, under 1-MHz ultrasound with a safe intensity of 212 mW/cm2, the as-developed device can produce an instantaneous effective output power of 280 μW, which can immediately activate the periaqueductal gray brain area. The rat electrophysiological experiments under anesthesia and behavioral experiments demonstrate that our wireless-powered device is well qualified for deep brain stimulation and analgesia applications. These encouraging results provide new insights into the development of implantable devices in the future.

Abstract
Renal cell carcinoma (RCC) is one of the most common malignancies in the urinary system. The mortality of advanced RCC remains high despite advances in systemic therapy of RCC. Considering the misdiagnosis of early-stage RCC, the identification of effective biomarkers is of great importance. Tissue inhibitor matrix metalloproteinase 1 (TIMP1), which belongs to TIMP gene family, is a natural inhibitor of the matrix metalloproteinases (MMPs). In this study, we found TIMP1 was significantly up-regulated in cell lines and RCC tissues. Kaplan-Meier analysis revealed that high expression of TIMP1 indicated a poor prognosis. Multivariate analysis further indicated that TIMP1 overexpression was an independent prognostic factor of RCC patients. Furthermore, knockdown of TIMP1 in vitro suppressed the proliferation, migration, and invasion of RCC cells, while upregulating TIMP1 accelerated the proliferation, migration, and invasion of RCC cells. In addition, we also found that TIMP1 prompted the progression of RCC via epithelial-to-mesenchymal transition (EMT) signaling pathway. In conclusion, the present results suggested that TIMP1 indicated poor prognosis of renal cell carcinoma and could serve as a potential diagnostic and prognostic biomarker for RCC.

Abstract
Mixed halide perovskites are promising memristive materials because of their excellent electronic-ionic properties. In this work, lead-free Cs2 AgBiBr6-x Clx (x=0, 0.2, 0.4, 0.6, 0.8, 1.0) double perovskite films were fabricated using a one-step solution spin-coating method in air. Moreover, the ITO/Cs2 AgBiBr6-x Clx /Al sandwich-like devices are fabricated to investigate the memristive behaviors. The present memristors exhibit nonvolatile and bipolar resistive switching behaviors without electroforming process. Interestingly, as the chloride content increases, the ON/OFF ratio of the device increases from 103 to 104 , the average SET voltage and the RESET voltage decrease from -0.40 V to -0.21 V and from 1.55 V to 1.34 V, respectively. In addition, resistance states of devices can be maintained after 100 switching cycles and 104 s of reading. This study provides new possibility for the development of low-power and environmentally friendly memristors.

Abstract
Background Increasing evidence indicated that the aberrant expression of the cytoplasmic FMR1-interacting protein (CYFIP) family might possess critical role and potential functions in cancer. But the role of CYFIP2 in clear cell renal cell carcinoma (ccRCC) is still uncharacteristic. Methods We investigated the Cancer Genome Atlas Kidney Clear Cell Carcinoma (TCGA-KIRC) database for the expression profile, clinicopathological variables, clinical prognosis information, and promoter methylation levels of CYFIPs in ccRCC. The aberrant CYFIP2 protein expression was validated by the Human Protein Atlas (HPA) and Clinical Proteomic Tumor Analysis Consortium (CPTAC). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to uncover CYFIP2 mRNA levels in 28 pairs of ccRCC cancer tissues. Kaplan–Meier analysis, univariate and multivariate Cox proportional hazard regression were performed to assess CYFIPs’ prognosis value. Gene set enrichment analysis (GSEA) was used to determined hallmark functions, gene ontology of CYFIP2. TIMER database was utilized to assess the correlation with immune infiltration in ccRCC. Results Results showed CYFIP2 was downregulated in ccRCC, relative to paired normal tissues in TCGA-KIRC database and 28 pairs of clinical samples (P < 0.0001). Similarly, a decreased CYFIP2 protein expression was confirmed by ccRCC tissues. The results showed CYFIP2 was negatively regulated by promoter DNA methylation. Survival analysis results showed CYFIP2 could be an independent biomarker for ccRCC and its reduction predicted a poor overall survival (OS) and disease-free survival (DFS). GSEA showed CYFIP2 was involved in metabolic pathways and epithelial–mesenchymal transition (EMT). Immune infiltration analysis revealed that a list of immune markers was significantly correlated with CYFIP2 expression especially with CD4+ cells and CD8+ cells in ccRCC. Conclusion These results show that CYFIP2 was downregulated in ccRCC patients and predicted an unfavorable prognosis. CYFIP2 might be a potential novel prognostic molecule, and related to immune infiltration, the metabolism, as well as EMT process in ccRCC. CYFIP2 could act as tumor suppressor gene in ccRCC and positive modulation of CYFIP2 might lead to development of a novel strategy for ccRCC treatment.

Abstract
Abstract
Aim
To explore the function(s) of HSP90 in intermediate monocyte-mediated plaque erosion.
Materials and methods
We used single-cell RNA sequencing to map cardiac immune response composition in patients with plaque rupture and plaque erosion. By focusing our analyses on CD14 positive monocytes, we obtained a higher resolution identification of the immune cell subsets in patients experiencing plaque erosion and rupture. We interpreted our findings with analyses using gene ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases and by performing receiver operating characteristic (ROC) curve analysis.
Results
Single-cell sequencing analysis of mononuclear cells in the peripheral blood of five ACS patients experiencing plaque erosion and rupture confirmed that CD14 positive monocytes were the main immune cells leading to ACS. Interestingly, our results suggested a significant increase in the proportion of atypical monocytes (C4 subsets) in patients with plaque rupture, which was a novel finding. This increase may be caused by increased migration of atypical monocytes into a plaque during plaque rupture. We found that intermediate monocyte activation was most obvious in patients with plaque erosion (C1, C10, and C11), and the proportion of C1 subgroup monocytes (FCGR3B/CMTM2 double strong positive; subsequently defined as intermediate monocytes) was very high. To further explore the role of C1 subgroup intermediate monocytes in plaque erosion, GO and KEGG pathway analyses were performed. GO analysis indicated that C1 subgroup intermediate monocytes are highly involved in neutrophil metabolism. Because neutrophils are the main effector cells that induce plaque erosion, we reasonably infer that intermediate monocytes can induce plaque erosion. KEGG pathway analysis indicated that all subtypes of HSP90 were highly expressed in C1 subgroup intermediate monocytes. We thus collected peripheral blood from ACS patients with plaque rupture (n=150) and plaque erosion (n=150) for mononuclear cell transcriptomics and intracellular proteomics analysis. ROC curve analysis demonstrated that the area under the curve for HSP90-based prediction was 0.86, indicating that HSP90 could be used to predict if patients would experience plaque erosion.
Conclusion
Activation of intermediate mononuclear HSP90 expression may be the crucial event that induces neutrophil hyper-responsiveness and leads to plaque erosion.

Abstract
In this study, yttrium-doped CH3NH3PbI3 (Y-MAPbI3) and pure CH3NH3PbI3 (MAPbI3) perovskite films have been fabricated using a one-step solution spin coating method in a glove box. X-ray diffractometry and field-emission scanning electron microscopy were used to characterize the crystal structures and morphologies of perovskite films, respectively. It was found that the orientation of the crystal changed and the grains became more uniform in Y-MAPbI3 film, compared with the pure MAPbI3 perovskite film. The films were used to prepare the resistive switching memory devices with the device structure of Al/Y-MAPbI3 (MAPbI3)/ITO-glass. The memory performance of both devices was studied and showed a bipolar resistive switching behavior. The Al/MAPbI3/ITO device had an endurance of about 328 cycles. In contrast, the Al/Y-MAPbI3/ITO device exhibited an enhanced performance with a long endurance up to 3000 cycles. Moreover, the Al/Y-MAPbI3/ITO device also showed a higher ON/OFF ratio of over 103, long retention time (≥104 s), lower operation voltage (±0.5 V) and outstanding reproducibility. Additionally, the conduction mechanism of the high resistance state transformed from space-charge limited current for a Y free device to the Schottky emission after Y doping. The present results indicate that the Al/Y-MAPbI3/ITO device has a great potential to be used in high-performance memory devices.

Abstract
Objective: To explore the current status of alcoholic hepatitis diagnosis by clinicians' in China. Methods: Clinical data of inpatients confirmed with alcohol-associated liver disease diagnosed at Tongliao Infectious Disease Hospital of Inner Mongolia from June 1, 2018 to May 31, 2019 were retrospectively analyzed. The consistency of clinical diagnosis of alcoholic hepatitis was judged according to the diagnostic criteria recommended by the National Institute of Alcohol Abuse and Alcoholism (USA), and then the alcoholic hepatitis severity assessment model recommended by international guidelines, including Maddrey discriminant function, Model for end-stage liver disease, and Glasgow alcoholic hepatitis score and ABIC scores (age, total bilirubin, international normalized ratio and creatinine) were applied to evaluate this group of cases. Results: Among 79 cases with alcohol-associated liver disease, 75 were males and 4 were females, age ranged between 27~75 (51.1±8.8) years. Alcohol consumption varied from 60 g/d to 600g/d, with an average consumption of 148.8 ± 76.6 g/d. The alcohol consumption duration ranged from 4 to 50 [average (23.9 ± 9.6)] years. According to the initial discharge diagnosis, there were 47 and 32 cases in alcoholic hepatitis and alcoholic liver cirrhosis group, respectively. The mean erythrocyte volume, serum alanine aminotransferase, aspartate aminotransferase and total bilirubin were increased in alcoholic liver cirrhosis than alcoholic hepatitis group, while albumin and total cholesterol were lowered in alcoholic liver cirrhosis than alcoholic hepatitis group, and coagulation indexes were significantly extended. Alpha-fetoprotein of both groups were in the normal range; however, it was significantly higher in the alcoholic hepatitis group than the alcoholic cirrhosis group. The 10 cases in the alcoholic cirrhosis group met the definition and diagnosis of alcoholic hepatitis defined by the National Institute of Alcohol Abuse and Alcoholism (USA), but there was no case in the alcoholic hepatitis group. Among the 10 diagnosed cases of alcoholic hepatitis, 5, 6, 1 and 3 cases met the diagnostic criteria of Maddrey discriminant function, Model for end-stage liver disease, Glasgow alcoholic hepatitis score, and ABIC score for severe alcoholic hepatitis, respectively. The Maddrey discriminant function, ABIC score, and Glasgow alcoholic hepatitis score within the Model for end-stage liver disease scores> 20 points had 5, 1, and 3 cases, respectively. Conclusion: Alcoholic hepatitis is over-diagnosed by clinicians. Alcoholic hepatitis patients have the base of liver cirrhosis who meet the diagnostic criteria of National Institute of Alcohol Abuse and Alcoholism (USA). Patients with Model for end-stage liver disease score > 20 points have good consistency with Maddrey discriminant function score ≥ 32 points, and both can be used to evaluate the alcoholic hepatitis patient clinical severity.

Abstract
Full-electrical writing and reading of magnetization states are vital for the development of next-generation spintronic devices with high density and ultralow-power consumption. Here, we proposed a method to realize the full-electrical writing and reading of magnetization states via a structural design, which only requires a symmetrical device structure and an antiparallel magnetic configuration. CrBr3, h-BN, and 1T-MnSe2 were selected to construct the device of CrBr3/h-BN/1T-MnSe2/h-BN/CrBr3, where the magnetization of two CrBr3 layers was fixed to the antiparallel state. By changing the direction and magnitude of the applied electric field, it is proved that the magnetization of 1T-MnSe2 could be reversed. Moreover, the device energies before and after the magnetization reversal are the same when the applied electric field is removed due to the structural symmetry. Meanwhile, the magnetic anisotropy energy of 1T-MnSe2 could induce an energy barrier, to guarantee the nonvolatile magnetization reversal in the present device. In addition, the tunnel magnetoresistance ratio was found up to 421%, showing a promising application to full-electrically write and read magnetization in spintronics. The present study likely promotes the development of full-electrical and ultralow-power spintronics devices.

Abstract
Ferroptosis is a novel form of cell death and plays a role in various diseases, especially tumors. It has been reported that ferroptosis is involved in the growth and progression of clear cell renal cell carcinoma (ccRCC); however, the specific molecular mechanisms are still unclear. In this study, we constructed a four-gene signature (FeSig) of ferroptosis-related genes via Cox regression analysis. ROC and survival analyses indicated that FeSig had good diagnostic and prognostic value. Further analysis revealed that ferroptosis was associated with tumor immunity in ccRCC. Next, weighted gene co-expression network analysis was performed to identify the potential regulatory mechanisms. Combined with correlation and survival analyses, the TAZ/WNT10B axis was identified as a tumor immune-related regulatory pathway. In conclusion, these findings suggest that ferroptosis is correlated with tumor immunity. The TAZ/WNT10B axis may be a novel biomarker and therapeutic target for immunotherapy in ccRCC.

Abstract
PPM-18, identified as a novel analog of vitamin K, has been reported to play a critical role in the suppression of seizures. However, the concerns that whether PPM-18, like vitamin K, exerts anticancer activity remain to be further investigated. Here, we found that PPM-18 remarkably suppressed the proliferation and induced apoptosis in bladder cancer cells. Furthermore, a significant autophagic effect of PPM-18 on bladder cancer cells was also demonstrated, which profoundly promoted apoptotic cell death. Mechanistically, PPM-18 activated AMP-activated protein kinase (AMPK), whereas it repressed PI3K/AKT and mTORC1 pathways in bladder cancer cells. Inhibition of AMPK markedly relieved PPM-18–induced autophagy and apoptosis, indicating that PPM-18 is able to induce autophagy and apoptosis in bladder cancer cells via AMPK activation. Moreover, reactive oxygen species (ROS) were notably accumulated in PPM-18–treated bladder cancer cells, and treatment with ROS scavengers not only eliminated ROS production but also abrogated AMPK activation, which eventually rescued bladder cancer cells from PPM-18–triggered autophagy and apoptotic cell death. In bladder cancer xenografts, the anticancer activities of PPM-18, including suppressing the growth of tumors and inducing autophagy and apoptosis in tumor cells, were also established. Collectively, this study was the first to demonstrate the anticancer effect of PPM-18 on bladder cancer cells in vitro and in vivo through eliciting autophagy and apoptosis via ROS and AMPK pathways, which might provide new insights into the potential utilization of PPM-18 for future bladder cancer treatment.

Abstract
Objective: To explore the relationship between triglyceride-glucose index (TyG) and non-alcoholic fatty liver disease (NAFLD). Methods: 25 535 cases who participated in the health check-ups at the First Hospital of China Medical University from January 2019 to December 2019 were selected as the eligible subjects. Logistic regression analysis and receiver operating characteristic curve were used to analyze the relationship between TyG index and NAFLD risk and its diagnostic value for NAFLD. Results: NAFLD prevalence was gradually increased with the increase of the TyG index. After adjusting for other potential influencing factors, compared with the first quarter of TyG in patient with NAFLD, the OR (95%CI) in the second, third, and fourth quarter were 1.677 (1.495 ~ 1.881), 2.707 (2.397 ~ 3.057) and 4.049 (3.482 ~ 4.710), respectively. Receiver operating characteristic curve analysis showed that the best cut-off value of TyG index for the diagnosis of NAFLD was 6.9, and the area under the curve was 0.816. The sensitivity and specificity were 77.66% and 70.51%, respectively. The combined application of TyG and ALT levels had higher diagnostic value. Conclusion: TyG, as a simple and convenient biosynthetic index, is closely related to the NAFLD. In addition, when the TyG index is ≥6.9, it has a high diagnostic value for NAFLD.

Abstract
Clear cell renal cell carcinoma (ccRCC) is characterized by its insensitivity to chemoradiotherapy and lacks effective diagnostic and prognostic biomarkers. In this study, we focused on the role of m6A RNA methylation regulators for tumor immunity. Based on the expression of 20 m6A regulators, consensus clustering was performed to divide patients into cluster1/cluster2 and showed that there was a survival difference between the two clusters. Through cox regression analysis, five hub m6A regulators were screened to construct a risk model. Further analysis showed that the risk score was an independent prognostic factor. GSEA, GSVA, and KEGG analysis revealed that immune cell pathways played a critical role between the high risk group and low risk group. Combined with CIBERSORT and survival analysis, five hub tumor-infiltrating immune cells (TIICs) were identified for further study. Meanwhile, correlation analysis indicated that IGF2BP2 was positively associated with activated memory CD4 T cell and METTL14 was negatively correlated to the regulatory T cell. Therefore, IGF2BP2 and METTL14 were regarded as key genes. Further study verified that only METTL14 possessed good diagnostic and prognostic value. Then, GSEA exhibited that METTL14 was mainly enriched in chemokine related pathways. We also found that CCL5 was negatively correlated to METTL14 and might serve as a potential target of METTL14. In conclusion, these findings suggest that the METTL14/CCL5/Tregs axis is a potential signaling pathway for regulating tumor immunity, and might become novel therapeutic targets for ccRCC.

Abstract
Autotransplantation is a surgical technique in which a donor tooth belonging to the same individual is repositioned into a surgically prepared socket or site of previous tooth extraction. It is beneficial in patients with teeth affected by agenesis, trauma, significant caries, and in teeth in a non-restorable condition or prognostically poor due to other pathology. It is particularly useful in paediatric patients, as properly transplanted teeth have a vital periodontium that allows for continuous growth and functional adaptation leading to preservation of the alveolar ridge. Technological advances in rapid prototyping combined with three-dimensional (3D) computed tomography (CT) have the ability to revolutionise autotransplantation. Preoperative planning for atraumatic extraction of the donor tooth and precise preparation of the recipient site with a rapid prototyped surgical template of the donor tooth considerably reduces the extra-alveolar time, and also reduces manipulation of the root sheath and periodontal ligament, and related trauma. This case series demonstrates the efficient and successful autotransplantation of various types of teeth with the use of a rapid prototyped surgical template produced from 3D CT. The use of this technology is expected to refine the surgical technique and improve treatment outcomes.

Abstract
Objective: To analyze the relationship between migration time and the prevalence of myopia of children and adolescents aged between 6 and 18 years old in Shenzhen. Methods: From April to May 2019, 26 618 children and adolescents from 14 schools in six streets of Baoan District, including Fuyong, Shajing, Xin'an, Xixiang, Songgang and Shiyan, were included in the study by using random cluster sampling method. The demographic characteristics, migration status, self-reported myopia, screen time in the last seven days, outdoor activities in the last one month and other information were collected through the questionnaire. The differences of myopia among children and adolescents with different characteristics were compared by χ2 test, and the relationship between migration time and the prevalence of myopia was analyzed by multivariate unconditional logistic regression model. Results: The age of 26 618 study participants was (12.37±3.49) years old, and the overall prevalence of myopia was 49.4%. Multivariate logistic regression analysis showed that after controlling for relevant confounding factors, compared with migrant children and adolescents of migrant workers who migrated for 1-2 years, those of migrant workers who had migrated for more than 6 years had a higher risk of myopia [OR (95%CI): 1.48 (1.14-1.92)]. After being grouped by phase of school, in the lower grade group of primary school, the children and adolescents of migrant workers who had migrated for more than 6 years had a higher risk of myopia compared with those of migrant workers who migrated for 1-2 years [OR (95%CI): 1.96 (1.20-2.74)]. In the high school group, compared with the children and adolescents of migrant workers who migrated for 1-2 years, those of migrant workers who had migrated for 3-5 years and ≥6 years had a higher risk of myopia [OR (95%CI): 6.03 (1.29-28.15) and 6.52 (1.51-28.11), respectively]. Conclusion: The migration time is related to the prevalence of myopia of the children and adolescents of migrant workers.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide and also become an emerging risk factor for liver-related complications, such as cirrhosis and hepatocellular carcinoma (HCC). The liver-related burden of NASH is likely to increase and nonalcoholic steatohepatitis (NASH) is probably to be the leading indication for liver transplantation by 2020, as a consequence of increased disease prevalence and of the lack of an effective treatment. The first step in the NAFLD development is represented by fat accumulation in the liver, a condition that is commonly associated with features of the metabolic syndrome. Notably, it has been acknowledged that the step from nonalcoholic fatty liver (NAFL) to NASH is key step in the NASH formation, and the mechanisms behind this transition have been extensively studied. Emerging evidence indicates that innate immunity is a driving force in NAFLD progression because it directly regulates all key pathogenic features of the disease processes, including metabolic dysregulation, inflammation, and fibrosis. In this review, we summarize the currently available signaling pathways of NASH formation, including oxidative stress, NOD-like receptors (NLRs), mitochondria-associated pathways, Toll-like receptors (TLRs), nuclear receptors, and other signal pathways, for the aim of a better understanding of this disease.

Abstract
RNA methylation accounts for over 60% of all RNA modifications, and N6-methyladenosine (m6A) is the most common modification on mRNA and lncRNA of human beings. It has been found that m6A modification occurs in microRNA, circRNA, rRNA, and tRNA, etc. The m6A modification plays an important role in regulating gene expression, and the abnormality of its regulatory mechanism refers to many human diseases, including cancers. Pitifully, as it stands there is a serious lack of knowledge of the extent to which the expression and function of m6A RNA methylation can influence prostate cancer (PC). Herein, we systematically analyzed the expression levels of 35 m6A RNA methylation regulators mentioned in literatures among prostate adenocarcinoma patients in the Cancer Genome Atlas (TCGA), finding that most of them expressed differently between cancer tissues and normal tissues with the significance of p < 0.05. Utilizing consensus clustering, we divided PC patients into two subgroups based on the differentially expressed m6A RNA methylation regulators with significantly different clinical outcomes. To appraise the discrepancy in total transcriptome between subgroups, the functional enrichment analysis was conducted for differential signaling pathways and cellular processes. Next, we selected five critical genes by the criteria that the regulators had a significant impact on prognosis of PC patients from TCGA through the last absolute shrinkage and selection operator (LASSO) Cox regression and obtained a risk score by weighted summation for prognosis prediction. The survival analysis curve and receiver operating characteristic (ROC) curve showed that this signature could excellently predict the prognosis of PC patients. The univariate and multivariate Cox regression analyses proved the independent prognostic value of the signature. In summary, our effort revealed the significance of m6A RNA methylation regulators in prostate cancer and determined a m6A gene expression classifier that well predicted the prognosis of prostate cancer.

Abstract
Abstract
Aims
To explore Sirt6 regulating autophagy in endothelial cells and the specific mechanism of this function with involvement of KLF4.
Materials and methods
Human umbilical vein endothelial cells were cultured with advanced glycation end products (AGE) treatment. Adv-Sirt6, LV-Sirt6 and LV-KLF4 were used to knockup Sirt6 and knockdown Sirt6 and KLF4 respectively. qPCR and Western Blotting were used to detect the mRNA and protein expression of Sirt6 and KLF4. Laser scanning confocal microscope was used to observe the LC3-II marked autophagosomes. Wildlife BALB/c mice were treated with STZ to produce diabetic mice model. AAV-Sirt6 was injected by tail vein injection to achieve Sirt6 knockdown. HE staining and scanning electron microscope were used to observe the aortic intima condition and autophagosomes number respectively.
Results
In AGE treated HUVECs, knockdown of Sirt6 led to impaired autophagy level along with less expression of autophagic markers LC3-II, Beclin-1, Lamp2 and autophagic marker p62. Knockdown and knockup of Sirt6 directly affected KLF4 expression level but KLF4 didn't have any effect on Sirt6 expression. Knockout of KLF4 offset the augmented autophagy caused by overexpression of Sirt6. In high-fat fed diabetic mice, downregulation of Sirt6 led to better cardiac function along with less autophagosomes and impaired aortic intima integrity.
Conclusions
Sirt6 improves autophagy both in vivo and in vitro and Sirt6 regulates autophagy via KLF4 in HUVECs.

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.

Abstract
BACKGROUND Up to 70% of patients with advanced ovarian cancer have a relapse after primary therapy. New agents and approaches are urgently needed to avoid or slow down this recurrence. OBJECTIVES To investigate the efficacy of PARP inhibitors (PARPis) as maintenance treatment in patients with newly diagnosed advanced ovarian cancer. SEARCH STRATEGY PubMed, MEDLINE, EMBASE, Cochrane Library and Web of Science databases. SELECTION CRITERIA All randomised clinical trials (RCTs) that compared PARPis with placebo as first-line maintenance therapy in ovarian cancer. DATA COLLECTION AND ANALYSIS Two reviewers extracted data. Pooled hazard ratio (HR) and risk ratio (RR) with 95% confidence interval (CI) were calculated. MAIN RESULTS PARPis were associated with significant improvement of progression-free survival (PFS) in advanced epithelial ovarian cancer (AeOC) (HR = 0.53, 95% CI 0.40-0.71; P < 0.0001). The benefit was not only in women with BRCA mutations (HR = 0.35, 95% CI 0.29-0.42; P < 0.00001) and homologous recombination deficiency (HRD) (HR = 0.43, 95% CI 0.32-0.60; P < 0.00001), but also in those with nonmutated BRCA (HR = 0.72, 95% CI 0.63-0.82; P < 0.00001) and even non-HRD (HR = 0.83, 95% CI 0.70-0.99; P = 0.04). CONCLUSIONS PARP inhibitors are effective as maintenance therapy among patients with newly diagnosed advanced ovarian cancer after platinum-based chemotherapy, regardless of BRCA mutation or HRD status. TWEETABLE ABSTRACT PARPis provide a significant PFS benefit as first-line maintenance therapy in patients with newly diagnosed advanced ovarian cancer.

Abstract
There is great interest in identifying a glucagon-like peptide-1 (GLP-1)-based combination therapy that will more effectively promote weight loss in patients with type 2 diabetes. Fibroblast growth factor 21 (FGF21) is a compelling yet previously unexplored drug candidate to combine with GLP-1 due to its thermogenic and insulin-sensitizing effects. Here, we describe the development of a biologic that fuses GLP-1 to FGF21 with an elastin-like polypeptide linker that acts as a sustained release module with zero-order drug release. We show that once-weekly dual-agonist treatment of diabetic mice results in potent weight-reducing effects and enhanced glycemic control that are not observed with either agonist alone. Furthermore, the dual-agonist formulation has superior efficacy compared to a GLP-1/FGF21 mixture, demonstrating the utility of combining two structurally distinct peptides into one multifunctional molecule. We anticipate that these results will spur further investigation into GLP-1/FGF21 multiagonism for the treatment of metabolic disease.

Abstract
The hind wings of beetles are deployable and play an essential role in flight. In the Asian ladybird Harmonia axyridis (Coleoptera: Coccinellidae), the pterostigma (pst) is found in the middle of the hind wing instead of at the tip of the hind wing. This paper investigates the effect of the pst on the vibrational characteristics during the flight of H. axyridis. Based on cross sections of the pst and veins as well as the morphology and nanomechanical properties of the hind wing, including the wing membrane and veins, three three-dimensional coupling models, Models I-III, of hind wings with/without pst structures and veins with varying or uniform reduced moduli are established. Modal analysis results for these three models show that the vibrational characteristics and deformation tendencies change the flight performance of the hind wing models with pst structures compared with that of the other models. The results in this paper reveal that the pst structure has an important influence on vibrational characteristics and deformation tendencies and, hence, on flight performance; the relationships between the body mass and the area of the hind wing, which have significant implications for the design of biomimetic deployable wing structures for micro air vehicles (MAVs), are also analyzed.

Abstract
Recently, cytoophidium, a nonmembrane-bound intracellular polymeric structure, has been shown to exist in various organisms, including tumor tissues, but its function and mechanism have not yet been examined. Examination of cytoophidia-assembled gene inosine monophosphate dehydrogenase (IMPDH) and cytidine triphosphate synthetase (CTPS) mRNA levels showed that only IMPDH1 levels were significantly higher in the clear cell renal cell carcinoma (ccRCC). IMPDH1 was positively correlated with the metastasis-related gene Y-box binding protein 1 (YB-1) and served as an independent prognostic factor in ccRCC. Kaplan-Meier analysis indicated that patients with tumors that expressed high IMPDH1 levels had a shorter overall survival (OS) and disease-free survival (DFS). Furthermore, detection of cytoophidia by immunofluorescence staining in ccRCC tissues showed that IMPDH1-assembled cytoophidia are positively associated with tumor metastasis. Mechanistically, IMPDH1 and YB-1 formed an autoregulatory positive feedback loop: IMPDH1 maintained YB-1 protein stabilization; YB-1 induced IMPDH1 expression by binding to the IMPDH1 promoter motif. Functionally, IMPDH1-assembled cytoophidia physically interacted with YB-1 and translocated YB-1 into the cell nucleus, thus correlating with ccRCC metastasis. Our findings provide the first solid theoretical rationale for targeting the IMPDH1/YB-1 axis to improve metastatic renal cancer treatment.

Abstract
Background Clear cell renal cell carcinoma (ccRCC), characterized by high mortality, invasion, metastasis, recurrence and drug resistance, is the most common malignant tumor of the urinary system. A clear understanding of the underlying molecular mechanisms and its role during tumorigenesis of RCC can contribute to development of prognostic and targeted therapies. Methods We analyzed datasets from the public database, TCGA, Oncomine, for differential expression of ubiquitin-specific protease 2 (USP2), and further investigated its relationship with the clinical stage, pathological grade and prognosis of renal cancer. We used real-time quantitative PCR and western blot analysis to validate USP2 expression in clinical samples and renal cancer cell lines. Finally, we used CCK-8 and transwell assays to determine its effects on biological functions in cells. Results We observed significantly lower levels of USP2 mRNA in renal cancer, relative to normal, tissues across the four datasets from the Oncomine database (P<0.001), 533 cases from TCGA database (P<0.0001) and 30 pairs of clinical samples (P<0.0001). Similarly, a decreased USP2 protein expression in ccRCC was detected following immunohistochemical (IHC) and western blot analyses. Furthermore, the aberrant expression of USP2 resulted in significant relationship with clinical stage, pathological grade and lower USP2 mRNA expression was interrelated to poor prognosis of renal cell carcinoma. USP2 acted as an independent factor for ccRCC diagnosis, with an AUC of 0.8888 (95% CI: 0.8529 to 0.9246; P<0.0001). Exogenous restoration of USP2 in ccRCC cells resulted in repression of cell proliferation, migration, and invasion. Conclusions Overall, these results show that USP2 acts as an anti-oncogene and an independent factor for ccRCC prognosis. Positive modulation of USP2 might lead to development of a novel strategy for ccRCC treatment.

Abstract
Photodynamic theranostics that allows for concurrent photodynamic therapy (PDT) and precise therapeutic response report has emerged as an intriguing direction in the development of precision medicine. An ultra-efficient photodynamic theranostics platform was developed here based on combining and potentiating a theranostic photosensitizer, TPCI, with other therapies for synergistic anticancer effect and synchronous self-reporting of therapeutic response. In this study, TPCI and a chemotherapy agent paclitaxel (PTX) were co-encapsulated in liposomes, which exhibited a superb synergistic anticancer effect against a series of tumor cell lines. The potency of both drugs had been boosted for up to 30-fold compared with sole PDT or chemotherapy. More strikingly, the released TPCI lighted up the nuclei of dead cells, triggered either by PDT or chemotherapy, through binding with the chromatin and activating its aggregation-induced emission, therefore self-reporting the anticancer effect of the combined therapy in real time. The in vivo study using a mouse model bearing PC3 prostate tumor cells demonstrated the effective ablation of tumors with initial sizes of 200 mm3 and the precise early tumor response monitoring by TPCI/PTX@Lipo. This PTX-potentiated photodynamic theranostics strategy herein represented a new prototype of self-reporting nanomedicine for precise tumor therapy.

Abstract
Cellular models of neurodevelopmental disorders provide a valuable experimental system to uncover disease mechanisms and novel therapeutic strategies. The ability of induced pluripotent stem cells (iPSCs) to generate diverse brain cell types offers great potential to model several neurodevelopmental disorders. Further patient-derived iPSCs have the unique genetic and molecular signature of the affected individuals, which allows researchers to address limitations of transgenic behavioural models, as well as generate hypothesis-driven models to study disorder-relevant phenotypes at a cellular level. In this article, we review the extant literature that has used iPSC-based modelling to understand the neuronal and glial contributions to neurodevelopmental disorders including autism spectrum disorder (ASD), Rett syndrome, bipolar disorder (BP), and schizophrenia. For instance, several molecular candidates have been shown to influence cellular phenotypes in three-dimensional iPSC-based models of ASD patients. Delays in differentiation of astrocytes and morphological changes of neurons are associated with Rett syndrome. In the case of bipolar disorders and schizophrenia, patient-derived models helped to identify cellular phenotypes associated with neuronal deficits (e.g., excitability) and mutation-specific abnormalities in oligodendrocytes (e.g., CSPG4). Further we provide a critical review of the current limitations of this field and provide methodological suggestions to enhance future modelling efforts of neurodevelopmental disorders. Future developments in experimental design and methodology of disease modelling represent an exciting new avenue relevant to neurodevelopmental disorders.

Abstract
Clear cell renal cell carcinoma (ccRCC) is one of the most common malignancies and lacks reliable biomarkers for diagnosis and prognosis, which results in high incidence and mortality rates of ccRCC. In this study, ISG20, HJURP, and FOXM1 were identified as hub genes via weighted gene co-expression network analysis (WGCNA) and Cox regression analysis. Samples validation showed that only ISG20 was up-regulated in ccRCC. Therefore, ISG20 was selected for further study. High ISG20 expression was associated with poor overall survival and disease-free survival. Furthermore, the expression of ISG20 could effectively differentiate ccRCC from normal tissues and was positively correlated to clinical stages. Functional experiments proved that knockdown of ISG20 expression could obviously inhibit cell growth, migration, and invasion in ccRCC cells. To find the potential mechanisms of ISG20, gene set enrichment analysis (GSEA) was performed and revealed that high expression of ISG20 was significantly involved in metastasis and cell cycle pathways. In addition, we found that ISG20 could regulate the expression of MMP9 and CCND1. In conclusion, these findings suggested that ISG20 promoted cell proliferation and metastasis via regulating MMP9/CCND1 expression and might serve as a potential biomarker and therapeutic target in ccRCC.

Abstract
Abstract
Background
The presence of an intra-cardiac mass is always a cause for concern, with regards to not only aetiology, but also treatment of complications. We describe a case series of 2 right sided cardiac myxomas, where the first case described an unusual location for tumour occurrence, while the second case provided insights into complications of a cardiac myxoma.
Methods
The first case involved a 70 year old asymptomatic lady who was referred for an additional heart sound. A transthoracic echocardiogram (TTE) showed a large, mobile 1.5 X 1.2 cm mass, attached to the atrial surface of septal tricuspid valve leaflet, prolapsing in and out of the right sided chambers. This was confirmed on transoesophageal echocardiogram (TEE). Cardiac MRI (magnetic resonance imaging) showed a similar mass attached to the septal tricuspid leaflet with features consistent with a myxoma. She was referred to cardiothoracic surgery, and 2 lobulated tumours arising the septal tricuspid valve and adjacent posterior leaflet were seen. The tumours were resected and a bio-prosthetic tricuspid valve replacement implanted. Histology of the tumours showed myxomatous degeneration of tricuspid valve, consistent with cardiac myxoma.
The second case was a 56 year old lady who had dyspnoea, pedal oedema and an elevated jugular venous pulse on examination. A TTE done showed a large 7 X 4 cm mass extending from the right atrium (RA) into the right ventricle (RV). The left ventricular ejection fraction was 35%. Cardiac MRI confirmed the presence of a large mass in the right ventricle that exerted pressure effects on the ventricular septum and RV anterior free wall. Intra-operatively, a large RA mass attached by a stalk to the fossa ovalis was seen. The mass was excised and histology was consistent with cardiac myxoma. A repeat transthoracic echocardiogram done 2 weeks later showed normalisation of the LVEF.
See images below for more information.
Conclusion
While myxomas are the most common benign cardiac tumours, they occur less commonly in the right atrium, and much less so on the tricuspid valve. Clinical manifestations range from being completely asymptomatic, as in the 1st case, to non-specific constitutional symptoms such as fever or general malaise, and to life-threatening complications. These include embolism to the pulmonary circulation, causing sudden death, or to the systemic circulation through an intra-cardiac shunt, causing strokes. This risk is increased if the tumour is large, polypoidal and friable. Large tumours can also cause obstructive symptoms and heart failure. Thus timely diagnosis with multi-modality imaging tools, and definitive treatment with complete resection of the tumour are essential. Continued monitoring for recurrences of the tumour, which can occur in 1-5% of all cases, should be performed as well.

Abstract
Abstract
Background
The unexpected presence of a left ventricular (LV) mass is always a cause of concern for physicians. This is especially so in the presence of a cerebrovascular accident and a recent cardiac event, where the hunt for a cardioembolic source begins. We describe a case of an unusual presentation of a LV thrombus masquerading as a cystic mass, where diagnosis was confirmed with multimodality imaging tools.
Purpose
A 58 year old Thai male first presented to the emergency department with left brachio-facial syndrome secondary to a right pre-central gyrus stroke. He had chest pain 2 days prior, and was pain free on admission. An electrocardiogram done showed an evolved anterior myocardial infarction.
Methods and Results
A transthoracic echocardiogram performed on the 4th day of admission revealed a mildly impaired left ventricular systolic function with an ejection fraction of 45%, and wall motion abnormalities in the left anterior descending artery territory. There was an apical gelatinous-like, cystic and mobile mass with soft flexible walls, measuring 2.4 X 2.1cm. Differentials at this point included cystic thrombus, hydatid cyst, capillary haemangioma and intracardiac tumour.
A cardiac MRI was performed which showed an irregular apical mass with features suggestive of fresh thrombus. The mass demonstrates hyperintensity T1-w FSE sequences (with and without fat sat), increased hyperintensity in T2-w triple IR FSE, with no increased uptake in first pass perfusion, T1-w post contrast, or early and late gadolinium enhancement images.
A repeat transthoracic echocardiogram done 11 days after anticoagulation showed a 50% reduction in the size of the mass.
See images below for more information.
Conclusion
In the era of early primary percutaneous coronary intervention and anticoagulation following an acute myocardial infarction (AMI), LV thrombus is an uncommon complication. It can occur within 2 weeks after an AMI, where increased blood stasis from dyskinesia or akinesia of associated wall segments, and a hypercoagulable state increases the risk of thrombus formation. A literature search has shown that presentation of the thrombus as a cystic mass is rare as well. As such, early diagnosis allowing for early treatment, especially when systemic embolism of thrombus is suspected, is important. Other causes of cystic LV thrombus do need to be considered in the relevant clinical context. These include infectious causes such as hydatid cyst, capillary hemangioma or intracardiac tumour, which are less likely given the history and investigation results. In this case, a trial of therapy with anticoagulation reduced the size of the cystic mass, and along with imaging findings, confirmed the diagnosis of a cystic LV thrombus.

Abstract
Metabolic adaptations are emerging hallmarks of cancer progression and cellular transformation. Clear cell renal cell carcinoma (ccRCC) is a metabolic disease defined histologically by lipid accumulation and lipid storage, which promote tumor cell survival; however, the significance of eliminating the lipid remains unclear. Here, we demonstrate that melatonin activates transcriptional coactivator peroxisome proliferator-activated receptor gamma coactivator 1A (PGC1A) and uncoupling protein 1 (UCP1)-dependent lipid autophagy and a lipid browning program to elicit a catabolic state called "tumor slimming," thus suppressing tumor progression. Metabolic coregulator data analysis revealed that PGC1A expression was decreased in ccRCC tissues versus normal tissues, and poor patient outcome was associated with lower expression of PGC1A in The Cancer Genome Atlas (TCGA-KIRC). PGC1A was downregulated in ccRCC and associated with disease progression. Restoration of PGC1A expression by melatonin in ccRCC cells significantly repressed tumor progression and eliminated the abnormal lipid deposits. Furthermore, a phenomenon called "tumor slimming" was observed, in which tumor cell volume was reduced and lipid droplets transformed into tiny pieces. Additional studies indicated that melatonin promoted "tumor slimming" and suppressed ccRCC progression through PGC1A/UCP1-mediated autophagy and lipid browning. During this process, autophagy and lipid browning eliminate lipid deposits without providing energy. These studies demonstrate that the novel "tumor slimming" pathway mediated by melatonin/PGC1A/UCP1 exhibits prognostic potential in ccRCC, thus revealing the significance of monitoring and manipulating this pathway for cancer therapy.

Abstract
Renal cell carcinoma (RCC) is one of the most common malignancies in the urinary system, among which the proportion of clear cell RCC (ccRCC) is over 80%. This study aims to explore potential signaling pathways and key biomarkers that drive RCC progression. The RCC GEO Datasets GSE15641 was featured to screen differentially expressed genes (DEGs). The pathway enrichment and functional annotation of differentially expressed genes were analyzed using the Kyoto Encyclopedia of Genes and Genomes (KEGG) and the Gene Ontology (GO). We screened Hub genes from DEGs using protein-protein interaction (PPI) networks and Cytoscape software. The survival and diagnostic analysis of these hub genes was performed to evaluate their potential prognostic and diagnostic value for ccRCC. In GSE15641 dataset, 598 DEGs were captured according to screening criteria (406 up-regulated genes and 192 down-regulated genes). Meanwhile, 15 hub genes were screened out from DEGs using PPI and Cytoscape. Kaplan Meier and ROC curve analysis identified three potential prognostic and diagnostic biomarkers (TGFB1, TIMP1 and VIM) for ccRCC from 15 hub genes. Gene set enrichment analysis (GSEA) revealed that these three dysregulated genes are mainly enriched in primary immunodeficiency, ECM receptor interaction, cytokine receptor interaction and natural killer cell-mediated cytotoxicity pathway. In summary, our findings discovered pivotal gene expression signatures and signaling pathways in the progression of ccRCC. TGFB1, TIMP1 and VIM might contribute to the progression of ccRCC, which could have potential as biomarkers or therapeutic targets for ccRCC.

Abstract
BACKGROUND Clear cell renal cell carcinoma (ccRCC) is one of the most common malignancies in urinary system. However, there are still no reliable biomarkers for the diagnosis and prognosis of ccRCC. In this study, we aimed to screen candidate biomarkers and potential therapeutic targets for ccRCC. METHODS Differentially expressed genes (DEGs) were screened using NetworkAnalyst. Protein-protein interaction (PPI) network and weighted gene co-expression network analysis (WGCNA) were utilized to identify hub genes. Then, we assessed the prognostic and diagnostic values of hub genes to screen candidate biomarkers. Gene Set Enrichment Analysis (GSEA) was applied to reveal potential mechanisms of candidate biomarkers in ccRCC. Oncomine database and The Human Protein Atlas were used to verify the expression of candidate biomarkers online. In addition, qRT-PCR, Enzyme linked immunosorbent assay (ELISA) and Immunohistochemistry (IHC) assays were performed to validate the expression level of candidate biomarkers in ccRCC cells and tissues. RESULTS A total of 771 genes were identified as DEGs. GO function analysis showed that DEGs were mostly enriched in excretion, apical part of cell and monovalent inorganic cation transmembrane transporter activity. KEGG pathway analysis demonstrated that DEGs were mostly involved in Neuroactive ligand-receptor interaction. After utilizing PPI network and WGCNA, nine genes (IFNG, CXCR3, PMCH, CD2, FASLG, CXCL13, CD8A, CD3D and GZMA) were identified as the hub genes. Moreover, survival analysis exhibited that high expression of CXCL13 predicted poor survival in both overall survival (OS) and disease free survival (DFS). The ROC curves indicated that CXCL13 could distinguish ccRCC samples from normal kidney samples. High expression of CXCL13 group was mostly associated with RB and MEL18 pathways by GSEA. Furthermore, qRT-PCR, ELISA and IHC results showed that the expression of CXCL13 was elevated in ccRCC. CONCLUSIONS Our study illustrated that CXCL13 had good diagnostic and prognostic value, which may become a candidate biomarker and therapeutic target for ccRCC.
