RESUMO
Sarcomatoid carcinoma of the renal pelvis accounts for a very low percentage of malignant tumors in the renal pelvis and has a poor prognosis. This article reported a patient with sarcomatoid carcinoma of the renal pelvis. The patient presented with macroscopic hematuria as the first symptom, and CT suggested left renal occupancy, unilateral nephrectomy was performed, and pathology suggested sarcomatoid carcinoma of the renal pelvis. Three weeks after surgery, a follow-up CT showed tumor recurrence. Programmed death 1(PD-1)inhibitor was given once every 3 weeks. Repeated CT examination after 24 weeks of continuous treatment suggested that the recurrent tumor disappeared. The patients was followed-up for 42 months without tumor recurrence or metastasis.
RESUMO
Objective:To assess the left ventricular myocardial function in non-ST-segment-elevation acute coronary syndrome (NSTE-ACS) patients with normal wall motion and left ventricular ejection fraction (LVEF) after percutaneous coronary intervention(PCI) by noninvasive myocardial work technology, and to explore the evolution of left ventricular myocardial function recovery.Methods:A total of 92 NSTE-ACS patients from July to December 2019 in Beijing Chao Yang Hospital with normal wall motion and LVEF (>55%) after PCI were recruited. Echocardiography was performed 1 day before PCI, 1 day, 2 weeks, 1 month, and 3 months after PCI. Global longitudinal strain (GLS) was analyzed, and Brachial cuff systolic pressure was used as left ventricular pressure to construct a non-invasive left ventricular pressure-strain loop. Global myocardial work index (GWI), global constructive work (GCW), global waste work (GWW), global myocardial work efficiency (GWE) among groups were compared and their correlations with strain parameters were explored.Results:GWI, GCW, GWE were improved ( P<0.05) at 1 day after PCI, GLS improved ( P<0.05) and GWW decreased ( P<0.05) at 2 weeks, LVEF improved ( P<0.05) at 1 month. Baseline GWI and GCW had a moderately negative correlation with GLS ( r=-0.67, -0.66; both P<0.05); GWW had a moderately positive correlation with mechanical dispersion(MD) and postsystolic shortening index(PSI) ( rs=0.45, 0.50; both P<0.05); GWE had a moderately negative correlation with GLS, MD and PSI ( rs=-0.47, -0.55, -0.56; all P<0.05). Conclusions:Left ventricular myocardial function gradually improves in NSTE-ACS patients with normal wall motion and LVEF after PCI. Myocardial work parameters changes are more sensitive than GLS and LVEF, and can assess early left ventricular myocardial function changes after PCI.
RESUMO
Objective:To assess global myocardial work in non-ST-segment-elevation acute coronary syndrome (NSTE-ACS) patients with no obvious regional wall motion abnormalities and preserved left ventricular ejection fraction (LVEF) by noninvasive left ventricular (LV) pressure-strain loops, and to explore its diagnostic value in patients with NSTE-ACS.Methods:A total of 169 NSTE-ACS patients with normal wall motion abnormalities and LVEF (>55%) were recruited in Beijing Chao Yang Hospital, Capital Medical University from June to December 2019. The patients were divided into two groups according to the degree of coronary stenosis, including severe coronary artery stenosis group ( n=121), and no severe stenosis group ( n=48). The patients of severe coronary artery stenosis group were further subdivided into single-vessel severe stenosis group ( n=52) and multi-vessel severe stenosis group ( n=69). Global longitudinal strain (GLS) analysis was performed by speckle tracking echocardiography before coronary angiography. Brachial cuff systolic pressure was used as left ventricular pressure to construct a non-invasive left ventricular pressure-strain loop. Global myocardial work index (GWI), global constructive work (GCW), global waste work (GWW) and global myocardial work efficiency (GWE) was computed by LV pressure-strain loops with a proprietary algorithm between groups. ROC curve analysis was used to determine the optimal cutoff value of the parameters to detect severe coronary artery stenosis. Independent factors affecting left ventricular myocardial function were assessed by Logistic regression analysis. Results:GLS, GWI, GCW and GWE were significantly reduced, and GWW was increased in severe coronary artery stenosis group than in no severe stenosis group(all P<0.05). GLS was significantly reduced in multi-vessel severe stenosis group ( P<0.05) but not in single-vessel severe stenosis group ( P=0.32). GWE was an independent factor affecting myocardial function in severe coronary artery stenosis group, GWE<96% had a area under the curve (AUC)=0.83 (74% for sensitivity, 81% for specificity) to identify severe coronary artery stenosis, and was superior to GLS (AUC=0.66, P<0.05) and GWI (AUC=0.70, P<0.05). Conclusions:In NSTE-ACS patients with severe coronary artery stenosis, no obvious regional wall motion abnormalities and preserved LVEF, LV global myocardial function is impaired based on noninvasive pressure-strain loops, GWI, GCW, and GWE are reduced, and GWW is increased, and GWE is a more sensitive index than GLS and GWI to predict severe coronary artery stenosis in NSTE-ACS patients.

RESUMO
Objective: To investigate the effect of vascular endothelial growth factor-C (VEGF-C) on invasive capability and proliferation of human cholangiocarcinoma cells. Methods: The effect of VEGF-C on FRH0201 was assayed by MTT. The cycle pattern and apoptosis was assayed using flow cytometry. The effect of VEGF-C on homotypic adhesion and metastasis in FRH0201 was examined with 3H-TdR infiltration and Boyden chamber. Results: VEGF-C could enhance the proliferation of FRH0201 in a dose and time dependent manner. And VEGF-C could inhibit cell apoptosis significantly. After cultured for 2 hours with 1, 5, 10ng/ml of VEGF-C, there were more cells in the lower chamber than the control group. After 60, 90, 120 minutes induction by 1ng/ml、5ng/ml、10ng/ml, the cells showed significantly lower homotypic adhesion than that of the control group. Conclusions: VEGF-C could enhance the proliferation of FRH0201 and inhibit cell apoptosis. VEGF-C could decrease homotypic adhesion of FRH0201 and might be a cause of the metastasis.
