Pulmonary large cell neuroendocrine carcinoma (LCNEC), which accounts for approximately 1% of all lung cancers, is a rare and highly aggressive malignancy with a poor prognosis. Therefore, it is important to devise an effective treatment strategy. In the treatment of locally advanced complex LCNEC, it is unique to first administer radiotherapy combined with albumin-bound paclitaxel plus carboplatin, followed by durvalumab for immune maintenance treatment after concurrent radiotherapy and chemotherapy to achieve complete remission.

Aberrant activation of Wnt/β-catenin signaling pathways is closely involved in the occurrence and progression of several types of human malignancies. However, as a fundamental component in this cascade, Wnt3 has not been well understood for the expression level and pathogenic mechanism in gastric carcinogenesis. Here, this research was undertaken to elucidate the important role of Wnt3 in gastric cancer.

This study tested the hypothesis that postconditioning attenuates the elevation of tumor necrosis factor-alpha (TNF-alpha) and improves heart function in patients with AMI after PCI.
Methods: A total of 75 patients were randomly assigned to 1 of 3 groups: the routine group (n = 26), in which no intervention was given at the onset of reperfusion; and the Postcon-30s (n = 25) or Postcon-60 s (n = 24) groups, in which 3 cycles of 30- or 60-second balloon deflation and inflation were repetitively performed.
Objective: To investigate the effects of ShenSongYangXin on action potential and some current channels in isolated rabbit pulmonary vein cardiomyocytes and to elucidate its possible mechanism of curing atrial fibrillation.
Methods: Action potentials as well as L-type calcium channel current (I(Ca-L)), transient outward potassium current (I(K1)) and inward rectifier potassium current (I(To)) were recorded using whole cell patch-clamp technique.
Results: ShenSongYangXin prolonged the action potential duration (APD) significantly, APD90 was enlarged from (187 +/- 49) ms to (286 +/- 76) ms at the concentration of 5 mg/ml and to (312 +/- 82) ms at the concentration of 10 mg/dl respectively (P < 0.

Different postconditioning (Postcon) methods have been demonstrated to protect heart from ischemia/reperfusion injury. The relationship between Postcon by percutaneous coronary intervention (PCI) and apoptosis is not clear. Our objective was to test whether Postcon by PCI in patients with acute myocardial infarction (AMI) reduces myocardial apoptosis.

Methods And Results: The EPCs were obtained from cultured mononuclear cells, which were isolated from the peripheral blood of healthy adults, and stimulated with CsA (10 microg/mL) in the presence or absence of either vascular endothelial growth factor (VEGF; 50 ng/mL) or L-arginine (1 mM). To explore the effect of different concentrations of CsA alone on EPC proliferation, some cells were treated with CsA in a series of final concentrations ranging from 0 to 10 microg/mL.
As a special focus in initiating and maintaining atrial fibrillation (AF), cardiomyocytes in superior vena cava (SVC) have distinctive electrophysiological characters. In this study, we found that comparing with the right atrial (RA) cardiomyocytes, the SVC cardiomyocytes had longer APD90 at the different basic cycle lengths; the conduction block could be observed on both RA and SVC cardiomyocytes. A few of SVC cardiomyocytes showed slow response action potentials with automatic activity and some others showed early after depolarization (EAD) spontaneously.

View Article and Find Full Text PDFTo investigate the characteristics of action potentials and their ionic mechanism in cardiomyocytes from rabbit pulmonary vein sleeves (PVC), and to compare them with those in left atrial cardiomyocytes (LAC), the technique of whole-cell patch clamp was applied. We used current-clamp technique to record action potentials, and voltage-clamp technique to record ionic currents. PVC had longer action potential duration (APD) than LAC, and therefore a second plateau response could be induced easily, suggesting a strong tendency of early afterdepolarization (EAD) genesis in PVC.
