Objective To observe the correlations of quantitative parameters of contrast-enhanced ultrasound(CEUS),micro-flow imaging(MFI)and shear wave elastography(SWE)with tumor microenvironment(TME)acidification in nude mice MCF7 breast cancer.Methods MCF7 human breast cancer cells were injected subcutaneously into 20 BALB/c-nu nude mice,and modeling was regarded as successful when tumor grew to 150-200 mm3.Then,CEUS,MFI and SWE were performed to obtain relevant parameters,including time-intensity curve(TIC)parameters(peak intensity[PI],area under the curve[AUC]),vessel index(VI)and maximum,median and mean Youngs modulus(Emax,Emed,Emean).Tumor pH value was measured using fluorescence quenching method,and its correlation with CEUS,MFI and SWE parameters were analyzed.Results pH value of MCF7 breast cancer tissue in nude mice was 6.05-6.43,with an average of 6.27±0.05,which in high perfusion area was significantly higher than in low perfusion area(P＜0.001).PI and AUC of TIC and VI were all positively correlated with pH value(r=0.661,0.611,0.768,all P＜0.001),while Emax,Emed and Emean were negatively correlated with pH value(r=-0.490,-0.562,-0.571,all P＜0.001).Conclusion TIC parameters and VI of MCF7 breast cancer in nude mice were positively correlated with TME acidification,while Emax,Emed and Emean were negatively correlated with TME acidification.

Radiotherapy plays a key role in the treatment of head and neck tumors, which can not only serve as a curative treatment, but also as an adjuvant treatment after surgery to improve the local control rate. In addition, radiotherapy also helps preserve important organ functions, such as laryngeal function or facial appearance, which is of great significance for the treatment and rehabilitation of patients. Despite advances in radiotherapy technology, some patients still experience resistance to radiation therapy, resulting in treatment failure. Non-coding RNA (ncRNA) is considered to be the main type of RNA transcription, which is usually not translated into proteins, and mainly functions through the interaction with proteins, chromatins and mRNAs, and is a molecular marker for a variety of tumors, involving tumor proliferation, apoptosis, invasion and migration, etc. Many studies have shown that dysregulated ncRNA play an important role in radiotherapy resistance in head and neck tumors. Therefore, this article reviews the research progress of ncRNA in radiotherapy resistance in head and neck tumors, aiming to better understand the role of ncRNA in the occurrence and development of radiotherapy resistance, and provide reference for formulating more effective strategies for preventing radiotherapy resistance.

Purpose To investigate the 18F-FDG PET/CT metabolic characteristics and the accuracy of diagnosis in post-traumatic osteomyelitis. Materials and Methods A total of 64 patients with post-traumatic fracture nonunion and suspected infection in Beijing Jishuitan Hospital were retrospectively analyzed. The PET/CT examinations were performed from May 2019 to April 2020. Qualitative and semi-quantitative evaluation methods were used to evaluate the diagnostic accuracy of 18F-FDG PET/CT in post-traumatic osteomyelitis. The diagnostic efficiency was compared among different laboratory indexes,such as erythrocyte sedimentation rate,C-reactive protein and leukocyte. Logistic regression was used to analyze parameters with diagnostic significance. Results Among 64 patients with post-traumatic fracture nonunion,37 were ultimately diagnosed with post-traumatic osteomyelitis. Among them,23 were confirmed through positive microbial cultures during surgery,and 14 were diagnosed based on clinical symptoms and follow-up results. The remaining 27 patients showed no signs of infection based on intraoperative microbial cultures (n=10) or clinical follow-up of more than six months (n=17). PET/CT correctly identified infections in 34 of the 37 infected cases and accurately ruled out infections in 23 of the 27 non-infected cases. The sensitivity,specificity,positive predictive value,negative predictive value and overall diagnostic accuracy of PET/CT were 91.89％,85.19％,89.47％,88.46％ and 89.06％,respectively. The maximum standardized uptake value (SUVmax) of PET/CT semi-quantitative parameter in the infection group (6.23±2.16) was higher than that in the non-infection group (4.24±1.86),showing a statistically significant difference (t=3.864,P<0.01). Logistic regression analysis revealed that SUVmax and C-reactive protein had diagnostic significance for distinguishing between groups,and SUVmax demonstrated higher diagnostic accuracy than C-reactive protein (x2=27.245,P<0.001). Conclusion The metabolic imaging features provided by 18F-FDG PET/CT imaging help to provide a more accurate reference for the diagnosis of post-traumatic osteomyelitis,which is worthy of clinical application.

Objective:To investigate the prognostic value and related factors of heart-type fatty acid binding protein (H-FABP) in patients with heart failure.Methods:A total of 877 consecutive patients who were admitted to heart failure care unit of Fuwai hospital and diagnosed as heart failure from July 2015 to July 2017 were enrolled in this study. Baseline serum H-FABP concentration was measured by fluorescence lateral flow immunoassay. According to serum H-FABP levels, patients were divided into three groups: low H-FABP group (H-FABP≤4.04 ng/ml, n=292), middle H-FABP group (H-FABP 4.04-7.02 ng/ml, n=292) and high H-FABP group (H-FABP≥7.02 ng/ml, n=293). The general clinical characteristics were collected and compared among the three groups. According to whether heart failure was caused by coronary artery disease or not, patients with heart failure were divided into ischemic heart failure and non-ischemic heart failure. Multivariate linear regression analysis was performed to explore the independent risk factors of H-FABP. The primary endpoint events were the composite of all-cause death or heart transplantation. Multivariate Cox regression analyses, receiver operating characteristic (ROC) curves, risk prediction tests with multivariate Cox regression model and Kaplan-Meier analyses were conducted to investigate the relationship between H-FABP and the prognosis of heart failure. Results:Multivariate linear regression analysis showed that age, coronary artery disease, alanine aminotransferase, uric acid and N-terminal pro-B type natriuretic peptide (NT-proBNP) were positively associated with H-FABP (β=0.012, 0.238, 0.001, 0.345 and 0.063 respectively,all P<0.05), while female, hemoglobin, albumin, sodium, and estimated glomerular filtration rate (eGFR) were negatively associated with H-FABP (β=-0.184, -0.006, -0.016, -0.034 and -0.006 respectively, all P<0.05). One hundred and nineteen patients (13.6%) lost to follow-up, and 246 patients (32.5%) suffered from all-cause death or heart transplantation during the median follow-up duration of 931 (412-1 185) days. Multivariate Cox regression analysis showed that baseline H-FABP (log 2H-FABP) level was the independent predictor of all-cause death or heart transplantation in patients with heart failure ( HR=1.39, P<0.001). ROC curves showed that baseline H-FABP was a predictor of all-cause death or heart transplantation in patients with heart failure within 3 months, 1 year and 2 years (areas under the curves were 0.69, 0.69 and 0.71 respectively), and the best cut-off values were 5.85 ng/ml, 6.54 ng/ml and 6.54 ng/ml respectively. Risk prediction test with multivariate Cox regression model showed that baseline H-FABP could provide additional prognostic value in predicting all-cause death or heart transplantation for patients with heart failure on top of basic model and baseline NT-proBNP ( P<0.001). Taking 6.54 ng/ml and trisected levels of H-FABP as cut-off values respectively, Kaplan-Meier analyses showed that the survival rates were significantly different among the two or three groups ( P<0.001). Subgroup analyses showed that baseline H-FABP (log 2H-FABP) level was an independent predictor of all-cause death or heart transplantation in patients with ischemic heart failure ( HR=1.74, P<0.001), as well as in patients with non-ischemic heart failure ( HR=1.28, P=0.027). Conclusions:Age, sex, coronary artery disease, hemoglobin, albumin, alanine aminotransferase, sodium, eGFR, uric acid and NT-proBNP are associated with H-FABP level. Baseline H-FABP level is an independent predictor of all-cause death or heart transplantation in patients with heart failure. On top of basic model and baseline NT-proBNP, baseline H-FABP could provide additional prognostic value in predicting adverse events for patients with heart failure.

Compared to conventional cancer treatment, combination therapy based on well-designed nanoscale platforms may offer an opportunity to eliminate tumors and reduce recurrence and metastasis. In this study, we prepared multifunctional microspheres loading I-labeled hollow copper sulfide nanoparticles and paclitaxel (I-HCuSNPs-MS-PTX) for imaging and therapeutics of W256/B breast tumors in rats. F-fluordeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) imaging detected that the expansion of the tumor volume was delayed (<0.05) following intra-tumoral (i.t.) injection with I-HCuSNPs-MS-PTX plus near-infrared (NIR) irradiation. The immunohistochemical analysis further confirmed the anti-tumor effect. The single photon emission computed tomography (SPECT)/photoacoustic imaging mediated by I-HCuSNPs-MS-PTX demonstrated that microspheres were mainly distributed in the tumors with a relatively low distribution in other organs. Our results revealed that I-HCuSNPs-MS-PTX offered combined photothermal, chemo- and radio-therapies, eliminating tumors at a relatively low dose, as well as allowing SPECT/CT and photoacoustic imaging monitoring of distribution of the injected agents non-invasively. The copper sulfide-loaded microspheres, I-HCuSNPs-MS-PTX, can serve as a versatile theranostic agent in an orthotopic breast cancer model.
