Suppressed Nonreciprocal Second-Harmonic Generation of Antiferromagnet MnPSe in the MnPSe/Graphene Heterostructure Due to Interfacial Magnon-Plasmon Coupling.

Interfacial coupling is one of the keys to manipulating magnetic/nonmagnetic two-dimensional (2D) heterostructures for novel functionalities. The MnPSe/graphene heterostructure is a prospective platform for quantum information and metrology. However, how graphene affects MnPSe through interfacial coupling is still poorly understood.

Molecular Structures of Poly(methyl methacrylate) at Different Buried Interfaces Revealed by Sum Frequency Generation Vibrational Spectroscopy.

Silica or calcium fluoride (CaF) substrate-supported poly(methyl methacrylate) (PMMA) thin films as insulating layers are commonly used in photoelectric/photovoltaic devices to improve the efficiency or stability of these devices. However, a comparative investigation of molecular structures at buried PMMA/silica and PMMA/CaF interfaces under thermal stimuli remains unexplored. In this study, we qualitatively and quantitatively revealed different molecular orderings and orientations of PMMA at two interfaces before and after annealing using sum frequency generation (SFG) vibrational spectroscopy.

Effects of Intervention Strategies-Based on Positive Psychology on the Emotional Cognition, Mental Health, and Recovery of Speech Function in Speech Disabilities.

Electrical Impedance Analysis for Lung Cancer: A Prospective, Multicenter, Blind Validation Study.

Hypothesis: Patients with cancer have different impedances or conductances than patients with benign normal tissue; thus, we can apply electrical impedance analysis (EIA) to identify patients with cancer.

Method: To evaluate EIA's efficacy and safety profile in diagnosing pulmonary lesions, we conducted a prospective, multicenter study among patients with pulmonary lesions recruited from 4 clinical centers (Zhongshan Hospital Ethics Committee, Approval No. 2015-16R and 2017-035(3).

[The Value of CD44 Mononuclear Cells and Spleen Stiffness Measurement in Minimal Residual Disease in Acute Myeloid Leukemia and Its Prognosis].

Objective: To investigate the value of CD44 mononuclear cells (MNC) and spleen stiffness measurement (SSM) in minimal residual disease (MRD) in acute myeloid leukemia (AML) and its prognosis.

Methods: Flow cytometry was used to detected the proportion of CD44 and CD24 MNC in 44 AML patients after induction chemotherapy. The SSM was tested by FS.

[Relationship between Leukocytes Derived Microparticles and Minimal Residual Disease and Prognosis of Acute Myeloid Leukemia].

Objective: To detect the relationship between leukocytes derived microparticle (CD45 MP) and minimal residual disease (MRD) and prognosis of acute myeloid leukemia (AML).

Methods: The expression of CD45 MP, CD44 MP and CD24 MP in peripheral blood of 47 AML patients at the time after induction chemotherapy were detected by using flow cytometry, and the relationship between MP, MRD and prognosis were analyzed.

Results: The percentages of CD45 MP, CD44 MP and CD24 MP in MRD positive group were significantly higher than those in MRD negative group.

Bone marrow-derived mesenchymal stem cells modulate autophagy in RAW264.7 macrophages via the phosphoinositide 3-kinase/protein kinase B/heme oxygenase-1 signaling pathway under oxygen-glucose deprivation/restoration conditions.

Background: Autophagy of alveolar macrophages is a crucial process in ischemia/reperfusion injury-induced acute lung injury (ALI). Bone marrow-derived mesenchymal stem cells (BM-MSCs) are multipotent cells with the potential for repairing injured sites and regulating autophagy. This study was to investigate the influence of BM-MSCs on autophagy of macrophages in the oxygen-glucose deprivation/restoration (OGD/R) microenvironment and to explore the potential mechanism.

Prolonged progression-free survival and overall survival are associated with diabetes mellitus but inversely associated with levels of blood glucose in patients with lung cancer.

Background: Previous studies have provided conflicting evidence about the increased overall survival (OS) in lung cancer patients with diabetes mellitus (DM) compared with those without DM. This study assessed progression-free survival (PFS)/OS in lung cancer patients with or without DM and tentatively analyzed the impact of blood glucose levels on PFS/OS in lung cancer patients.

Methods: Data were collected from lung cancer patients based upon admission records from January 2010 to January 2012 and follow-up records from January 2010 to January 2015 in the Department of Pulmonary Medicine, Zhongshan Hospital, Fudan University, Shanghai.

Direct factor Xa inhibition attenuates acute lung injury progression via modulation of the PAR-2/NF-κB signaling pathway.

The role of coagulation in acute lung injury (ALI) remains unclear. As factor Xa-dependent protease-activated receptor 2 (PAR-2) is reported to be an important target in blood coagulation and other processes, an inhibitor of factor Xa, rivaroxaban, was tested in C57BL/6 mice with ALI induced by intratracheal injections of lipopolysaccharide (LPS) and in LPS-stimulated human umbilical vein endothelial cells. Plasma concentrations and coagulation indices were measured in mice fed normal chow or chow containing rivaroxaban (0.

Duodenal cryptococcus infection in an AIDS patient: retrospective clinical analysis.

Cryptococcal infection primarily affects the lung or the central nervous system and rare cases have been reported involving the gastrointestinal tract. However, among patients with HIV/AIDS, the gastrointestinal involvement is increasing. According to the PubMed search results, there were seven cases reported involving duodenal cryptococcosis combined with AIDS in five reports.

Decompression of acute left-sided malignant colorectal obstruction: comparing transanal drainage tube with metallic stent.

Background And Aim: Acute left-sided colorectal malignant obstruction is a life-threatening condition and need emergent treatment. Many nonsurgical treatments to palliate obstruction have been developed in clinics. The aim of this study was to evaluate the clinical effects of transanal drainage tube (TDT) and metallic stent for the decompression of acute left-sided malignant colorectal obstruction.

Covered stents versus uncovered stents for the palliation of malignant extrahepatic biliary obstruction caused by direct tumor invasion: a cohort comparative study.

Biliary stenting is a well-established palliative treatment in patients with unresectable malignant biliary strictures. The aim of the present study was to compare clinical outcomes of covered and uncovered stents in patients with malignant extrahepatic biliary obstruction caused by direct tumor invasion. Patients diagnosed with malignant extrahepatic biliary obstruction caused by direct tumor invasion were enrolled in this study.

Human ether-a-go-go-related gene K+ channels regulate shedding of leukemia cell-derived microvesicles.

Microvesicles (MVs) are released by various cancer cells, including leukemia cells. They can "hijack" membrane components from their parental cells and exert pleiotropic effects on tumor progression. Human ether-a-go-go-related gene (hERG1) K(+) channels are highly expressed in cancer cells and appear of exceptional importance in favoring cancer development.

Detection of circulating tumor cells and tumor stem cells in patients with breast cancer by using flow cytometry: a valuable tool for diagnosis and prognosis evaluation.

Circulating tumor stem cells (CTSC), a subpopulation of circulating tumor cells (CTC), may lead to recurrent diseases. The aim of this study was to detect CTC (CD45(-)EpCAM(+)) and CTSC (CD45(-)EpCAM(+)CD44(+)CD24(-)) of breast cancer (BC) patients, as well as to explore their clinical relevance. CTC and CTSC in peripheral blood (PB) of 45 female BC patients were detected by using flow cytometry (FCM).
