The construction and application of novel highly efficient photocatalysts have been the focus in the field of environmental pollutant removal.In this work,a novel CuFe_(2)O_(4)/Bi_(12)O_(17)Cl_(2)photocatalysts were synthesized by simple hydrothermal and chemical precipitation method.The fabricated CuFe_(2)O_(4)/Bi_(12)O_(17)Cl_(2)composite exhibited much higher photocatalytic activity than pristine CuFe_(2)O_(4)and Bi_(12)O_(17)Cl_(2)in the removal of bisphenol A(BPA)under visible-light illumination,which ascribed to the intrinsic p-n junction of CuFe_(2)O_(4)and Bi_(12)O_(17)Cl_(2).The photocatalytic degradation rate of BPA on CuFe_(2)O_(4)/Bi_(12)O_(17)Cl_(2)with an optimized CuFe_(2)O_(4)content(1.0 wt.%)reached 93.0%within 30 min.The capture experiments of active species confirmed that the hydroxyl radicals(·OH)and superoxide radicals(·O_(2)^(-))played crucial roles in photocatalytic BPA degradation process.Furthermore,the possible degradation mechanism and pathways of BPA was proposed according to the detected intermediates in photocatalytic reaction process.

Silver nanoparticles in size of 8.0 nm was prepared by the trisodium citrate and used to label goat anti-human fibrinogen. In the pH 5.8 Na2HPO4-NaH2O4 buffer solution (PBS) and in the presence of polyethylene glycol (PEG) and KCl, the immune reaction between silver-labeled goat anti-human fibrinogen and fibrinogen took place and led the resonance scattering intensity at 465 nm (I465) to decreasing. The I465 decreased intensity was linear to the fibrinogen concentration in the range from 0.067 to 1.67 μg/mL, with a detection limit of 0.024 μg/mL. This method was applied to determination of fibrinogen in human plasma, with satisfactory results.

Background:Endoscopic resection bleeding(ERB)classification was proposed by the authors’team to evaluate the severity of intraoperative bleeding(IB)during endoscopic submucosal dissection(ESD).This study aimed to evaluate the application of ERB classification and to analyze the risk factors of major IB(MIB)and postoperative bleeding(PB)associated with ESD for gastric neoplastic lesions.Methods:We retrospectively enrolled a total of 1334 patients who underwent ESD between November 2006 and September 2019 at The First Medical Center of Chinese People’s Liberation Army General Hospital.All patients were divided into the non-MIB group(including ERB-0,ERB-controlled 1[ERB-c1],and ERB-c2)and the MIB group(including ERB-c3 and ERB-uncontrolled[ERB-unc])according to the ERB classification.Risk factors of major MIB and risk factors of PB were analyzed using a logistic regression model.Results:Among the 1334 patients,773(57.95%)had ERB-0,477(35.76%)had ERB-c1,77(5.77%)had ERB-c2,7(0.52%)had ERB-c3,and no patients had ERB-unc.The rate of PB in patients with IB classifications of ERB-0,ERB-c1,ERB-c2,and ERB-c3 were 2.20%(17/773),3.35%(16/477),9.09%(7/77),and 2/7,respectively.In multivariate analysis,proximal location(odds ratio[OR]:1.488;95%confidence interval[CI]:1.045-3.645;P=0.047)was the only significant risk factor of MIB.Chronic kidney disease(CKD)(OR:7.844;95%CI:1.637-37.583;P=0.010)and MIB(ERB-c3)(OR:13.932;95%CI:2.585-74.794;P=0.002)were independent risk factors of PB.Conclusions:Proximal location of lesions was a significant risk factor of MIB.Additionally,CKD and MIB(ERB-c3)were independent risk factors of PB.More attention should be paid to these high-risk patients for MIB and PB.

Many previous studies have confirmed the effectiveness and safety of peroral endoscopic myotomy(POEM)to treat achalasia.However,severe interlayer adhesions preclude the establishment of a submucosal tunnel and then result in aborted POEM procedures.To address this challenge,we introduced POEM with simultaneous submucosal and muscle dissection(POEM-SSMD)in 2014.[1]During the short-term follow-up,the symptoms of the patient were significantly improved.Thus,for patients with esophageal interlayer adhesions,the relative indications of POEM may be extended.Nevertheless,only a few case reports using this technique with a shorter follow-up have been published to date.Hence,the present study aimed to further report the long-term outcomes of POEM-SSMD for achalasia with severe interlayer adhesions in a relatively larger population.

目的分析卵巢癌患者磁共振动态增强(DCE-MRI)联合高b值弥散加权成像(DWI)检查的表现。方法回顾性分析延安大学咸阳医院在2020年6月至2023年6月收治的50例确诊为卵巢癌患者的临床资料,作为观察组,并选取同期体检健康者50例为对照组。对照组年龄(33.58±5.47)岁;观察组年龄(33.37±5.53)岁,国际妇产科联盟(FIGO)分期Ⅰ期8例、Ⅱ期25例、Ⅲ期12例、Ⅳ期5例。两组受试者均接受DCE-MRI及高b值DWI检查,比较两组受试者的DCE-MRI定量参数,包括容量转移常数(Ktrans)、速率常数(Kep)、血管外细胞外容积分数(Ve);观察并比较两组DWI表观弥散系数(ADC)情况;绘制受试者操作特征曲线(ROC),计算曲线下面积(AUC)评估DCE-MRI联合高b值DWI检查对卵巢癌患者的诊断效能。采用F检验。结果观察组Ktrans、Kep、Ve分别为(0.43±0.05)min、(0.85±0.13)min、(0.75±0.25),均高于对照组的(0.07±0.06)min、(0.27±0.12)min、(0.26±0.16),观察组ADC值为(0.93±0.13)×10^(-3) mm^(2)/s,低于对照组的(1.53±0.23)×10^(-3) mm^(2)/s,差异均有统计学意义(均P<0.05);Ⅳ期患者Ktrans、Kep、Ve高于Ⅲ期,Ⅲ期高于Ⅱ期,Ⅱ期高于Ⅰ期,Ⅳ期患者ADC值低于Ⅲ期,Ⅲ期低于Ⅱ期,Ⅱ期低于Ⅰ期,差异均有统计学意义(均P<0.05)。经ROC分析,DCE-MRI对卵巢癌不同分期的诊断灵敏度为85.35%,特异度为90.14%,高b值DWI对卵巢癌不同分期的诊断灵敏度为82.45%,特异度为87.14%,DCE-MRI联合高b值DWI对卵巢癌不同分期的诊断灵敏度为94.14%,特异度为95.85%。结论DCE-MRI联合高b值DWI检查应用于卵巢癌患者具有更高效能,显著优于单项检测;当b值为1600 s•mm^(-2)时,结合DCE-MRI对卵巢癌的临床分期诊断具有更高的灵敏度和特异度;作为临床无创诊断辅助手段,两种检查方式可互为补充,避免卵巢癌的误诊,对患者治疗和预后具有重要临床价值。
