BACKGROUND Postpartum depression(PPD)not only affects the psychological and physiological aspects of maternal health but can also affect neonatal growth and development.Partners who are in close contact with parturient women play a key role in communication and emotional support.This study explores the PPD support relationship with partners and its influencing factors,which is believed to establish psychological well-being and improve maternal partner support.AIM To explore the correlation between PPD and partner support during breastfeeding and its influencing factors.METHODS Convenience sampling was used to select lactating women(200 women)who underwent postpartum examinations at the Huzhou Maternity and Child Health Care Hospital from July 2022 to December 2022.A cross-sectional survey was conducted on the basic information(general information questionnaire),depression level[edinburgh postnatal depression scale(EPDS)],and partner support score[dyadic coping inventory(DCI)]of the selected subjects.Pearson’s correlation analysis was used to analyze the correlation between PPD and DCI in lactating women.Factors affecting PPD levels during lactation were analyzed using multiple linear regression.RESULTS The total average score of EPDS in 200 lactating women was(9.52±1.53),and the total average score of DCI was(115.78±14.90).Dividing the EPDS,the dimension scores were:emotional loss(1.91±0.52),anxiety(3.84±1.05),and depression(3.76±0.96).Each dimension of the DCI was subdivided into:Pressure communication(26.79±6.71),mutual support(39.76±9.63),negative support(24.97±6.68),agent support(6.87±1.92),and joint support(17.39±4.19).Pearson’s correlation analysis demonstrated that the total mean score and individual dimension scores of EPDS during breastfeeding were inversely correlated with the total score of partner support,stress communication,mutual support,and cosupport(P<0.05).The total mean score of the EPDS and its dimensions were positively correlated with negative support(P<0.05).Multiple linear regression analy

Based on the in-situ self-reduction and chemical stability,graphdiyne（GDY） and graphdiyne oxide（GDYO） are used as trapping agents to investigate the ability for recovering Au3+,Ag+,and Pd2+under different pH values and interfering ions.Under strong acidity at pH=1,these two agents demonstrate high select recovery towards the three precious metal ions,which could be insitu reduced to nanoparticles（NPs）.In addition,superparamagnetic Fe3O4NPs are deposited on the surfaces of GDY and GDYO.The magnetic responses enable GDYFe3O4to recover precious metals conveniently and efficiently by the aid of an external magnetic field.This study also confirms the antibacterial activity of the as-recovered NPs deposited on GDY and GDYO against Escherichia coli and Staphylococcus aureus(1 × 10～5 colony-forming unit（CFU）·ml-1),and the antibacterial rates are 100%.This strategy of recovering precious metals and subsequently reusing to combat pathogens will be of great significance for environmental remediation and biomedical applications.

With the shortage of lithium resources,sodiumion batteries（SIBs） are considered one of the most promising candidates for lithium-ion batteries.P2-type and O3-type layered oxides are one of the few cathodes that can access high energy density.However,they usually exhibit structural change,capacity decay,and slow Na ion kinetic.Herein,we present layered ternary-phase cathodes with P2,P3 and O3 phases by a lattice doping strategy,which is demonstrated by X-ray diffraction（XRD） refinement.Combining the characteristics of P2,P3 and O3 phases,the layered composites show performance improvement during long-term battery cycling.In particular,Na0.7Li0.1Co0.3-Fe0.3Mn0.3O2（NLCFM） delivers a reversible capacity of120.1 mAh·g-1at 0.1C(1.0C=175 mA·g-1) with a superior capacity retention of 72.5% after 1000 cycles at10.0C.This work offers insights into the development of advanced cathode materials for SIBs.

Rare Metals 2024年第6期43卷 2527-2535页

作者： ming-ji Peng jin-Qiu Zhou Ting-Ting Han Yang Zhou jie Liu Na Xu Zhen-Kang Wang Wen-Bin Lin Cheng-Lin Yan Key Laboratory of Core Technology of High Specific Energy Battery and Key Materials for Petroleum and Chemical Industry College of EnergySoochow University Light Industry Institute of Electrochemical Power Sources School of Chemistry and Chemical Engineering Nantong University State Key Laboratory of Space Power-Sources Technology Shanghai Institute of Space Power-Sources Centre énergie Matériaux et TélécommunicationsInstitut National de la Recherche Scientifique Zhangjiagang Industrial Technologies Soochow University

Owing to the unique structure,anode-free lithium metal batteries（AFLMBs） have higher energy density and lower production cost than traditional lithium metal batteries（LMBs） or lithium-ion batteries（LIBs）,However,AFLMBs suffer from an inherently finite Li reservoir and exhibit poor cycle stability,low Coulombic efficiency（CE） and severe dendrite growth.In this work,polydiallyl lithium disulfide（PDS-Li） was successfully synthesized and coated on Cu current collector by electrochemical polymerization.The PDS-Li acts as an additional lithium resource to compensate for the irreversible loss of lithium during cycling.In addition,the special structure and lithiophilicity of PDS-Li contribute to lower nucleation overpotential and uniform lithium deposition.When coupled with Li-rich manganese-based（LRM）cathode of Li1.2Mn0.54Ni0.13Co0.13O2,the anode-free full cell exhibits significantly improved cycle stability over 100 cycles and capacity retention of 63.3% and 57% after 80 and 100 cycles,respectively.We believe that PDS-Li can be used to ensure stable cycling performance and high-energy-density in AFLMBs.

Acta Pharmaceutica Sinica B 2023年第12期13卷 4733-4747页

作者： mingjin Wang Weida Wang Shen You Zhenyan Hou ming ji Nina Xue Tingting Du Xiaoguang Chen jing jin Department of Pharmacology State Key Laboratory of Bioactive Substances and Functions of Natural MedicinesInstitute of Materia MedicaChinese Academy of Medical Sciences and Peking Union Medical CollegeBeijing 100050China

Glioblastoma(GBM)is a highly aggressive and lethal brain tumor with an immunosuppressive tumor microenvironment(TME).In this environment,myeloid cells,such as myeloid-derived suppressor cells(MDSCs),play a pivotal role in suppressing antitumor immunity.Lipometabolism is closely related to the function of myeloid cells.Here,our study reports that acetyl-CoA acetyltransferase 1(ACAT1),the key enzyme of fatty acid oxidation(FAO)and ketogenesis,is significantly downregulated in the MDSCs infiltrated in GBM patients.To investigate the effects of ACAT1 on myeloid cells,we generated mice with myeloid-specific(LyzM-cre)depletion of ACAT1.The results show that these mice exhibited a remarkable accumulation of MDSCs and increased tumor progression both ectopically and orthotopically.The mechanism behind this effect is elevated secretion of C-X-C motif ligand 1(CXCLI)of macrophages(Mo).Overall,our findings demonstrate that ACAT1 could serve as a promising drug target for GBM by regulating the function of MDSCs in the TME.

BACKGROUND Colorectal laterally spreading tumors(LSTs)with malignant potential require en bloc resection by endoscopic submucosal dissection(ESD),but lesions with deep submucosal invasion(SMI)are endoscopically unresectable.AIM To investigate the factors associated with high-grade dysplasia(HGD)/carcinoma and deep SMI in colorectal LSTs.METHODS The endoscopic and histological results of consecutive patients who underwent ESD for colorectal LSTs in our hospital from June 2013 to March 2019 were retrospectively analyzed.The characteristics of LST subtypes were compared.Risk factors for HGD/carcinoma and deep SMI(invasion depth≥1000μm)were determined using multivariate logistic regression.RESULTS A total of 323 patients with 341 colorectal LSTs were enrolled.Among the four subtypes,non-granular pseudodepressed(NG-PD)LSTs(85.5%)had the highest rate of HGD/carcinoma,followed by the granular nodular mixed(G-NM)(77.0%),granular homogenous(29.5%),and non-granular flat elevated(24.2%)subtypes.Deep SMI occurred commonly in NG-PD LSTs(12.9%).In the adjusted multivariate analysis,NG-PD[odds ratio(OR=16.8,P<0.001)and G-NM(OR=7.8,P<0.001)subtypes],size≥2 cm(OR=2.2,P=0.005),and positive non-lifting sign(OR=3.3,P=0.024)were independently associated with HGD/carcinoma.The NG-PD subtype(OR=13.3,P<0.001)and rectosigmoid location(OR=8.7,P=0.007)were independent risk factors for deep SMI.CONCLUSION Because of their increased risk for malignancy,it is highly recommended that NG-PD and G-NM LSTs are removed en bloc through ESD.Given their substantial risk for deep SMI,surgery needs to be considered for NG-PD LSTs located in the rectosigmoid,especially those with positive nonlifting signs.

Background:Endoscopic retrograde cholangiopancreatography(ERCP)is the endoscopic modality of choice for the treatment of biliary and pancreatic diseases.However,patients with cirrhosis,particularly those with decompensated cirrhosis,are believed to be at increased risk for complications associated with ERCP.There is a paucity of literature describing the outcomes of ERCP for patients with cirrhosis.This study aimed to investigate the outcomes of ERCP for cirrhosis patients,especially adverse events,and evaluated its safety and efficacy.Methods:We performed a multicenter,retrospective study of all patients at Beijing Friendship Hospital affiliated to Capital Medical University,Xijing Hospital affiliated to Air Force Military Medical University,Beijing Youan Hospital affiliated to Capital Medical University,and the Fifth Medical Center of the People’s Liberation Army General Hospital from June 2003 to August 2019.The adverse events of inpatient ERCP for patients with(n=182)and without liver cirrhosis(controls;n=385)were compared.Results:A total of 567 patients underwent ERCP between January 2003 and December 2019 were enrolled in this study.Compared to patients without cirrhosis,patients with cirrhosis were at higher risk for postoperative complications(odds ratio[OR],4.172;95%confidence interval[CI],1.232–7.031;P<0.001)such as postoperative pancreatitis(OR,2.026;95%CI,1.002–4.378;P=0.001)and cholangitis(OR,3.903;95%CI,1.001–10.038;P=0.036).The main indications for ERCP for patients with cirrhosis in this study included choledocholithiasis(101 cases;55.5%),benign bile duct strictures(46 cases;25.3%),and malignant bile duct strictures(28 cases;15.4%).Among them,23 patients(12.6%)underwent balloon dilation and 79 patients(43.4%)underwent sphincterotomy.Of the patients with cirrhosis,delayed bleeding occurred in ten patients(5.5%),postoperative pancreatitis occurred in 80 patients(44.0%),and postoperative cholangitis occurred in 25 patients(13.7%).An additional multivariate analysis showed that the total bilirubin(TBI

PD-1 and PD-L1 antibodies have brought about extraordinary clinical benefits for cancer patients,and their indications are expanding incessantly.Currently,most PD-1/PD-L1 agents are administered intravenously,which may be uncomfortable for some cancer patients.Herein,we develop a novel oral-delivered small molecular,YPD-29B,which specifically targets human PD-L1.Our data suggested that YPD-29B could potently and selectively block the interaction between PD-L1 and PD-1,but did not inhibit any other immune checkpoints.Mechanistically,YPD-29B induced human PD-L1 dimerization and internalization,which subsequently activated T lymphocytes and therefore overcomes immunity tolerance in vitro.YDP-29B was modified as the YPD-30 prodrug to improve druggability.Using humanized mice with human PD-1 xenografts of human PD-L1 knock-in mouse MC38 cancer cells,we demonstrated that YPD-30 exhibited significant antitumor activity and was well tolerated in vivo.Taken together,our results indicate that YPD-30 serves as a promising therapeutic candidate for anti-human PD-L1 cancer immunotherapy.

Glioblastoma is carcinogenesis of glial cells in central nervous system and has the highest incidence among primary brain tumors.Brain metastasis,such as breast cancer and lung cancer,also leads to high mortality.The available medicines are limited due to blood-brain barrier.Abnormal activation of phosphatidylinositol 3-kinases(PI3 K)signaling pathway is prevalent in glioblastoma and metastatic tumors.Here,we characterized a 2-amino-4-methylquinazoline derivative XH30 as a potent PI3 K inhibitor with excellent anti-tumor activity against human glioblastoma.XH30 significantly repressed the proliferation of various brain cancer cells and decreased the phosphorylation of key proteins of PI3 K signaling pathway,induced cell cycle arrest in G1 phase as well.Additionally,XH30 inhibited the migration of glioma cells and blocked the activation of PI3 K pathway by interleukin-17 A(IL-17 A),which increased the migration of U87 MG.Oral administration of XH30 significantly suppressed the tumor growth in both subcutaneous and orthotopic tumor models.XH30 also repressed tumor growth in brain metastasis models of lung cancers.Moreover,XH30 reduced IL-17 A and its receptor IL-17 RA in vivo.These results indicate that XH30 might be a potential therapeutic drug candidate for glioblastoma migration and brain metastasis.
