Objective:To observe and follow up the effect of transcatheter occlusion of the azygos/hemiazygos veins in patients with complex congenital heart diseases and venous stealing after bidirectional Glenn procedure, who had not meet the criteria of total cavopulmonary connection(TCPC) or corrective operation.Methods:This article analyzed retrospectively and followed up the effect of transcatheter occlusion of the azygos/hemiazygos vein in patients after bidirectional Glenn procedure hospitalized during February 2012 to September 2017.Results:Transcatheter occlusions of azygos veins were performed in 21 patients and left superior vena cava(LSVC) was occluded in one of patients meanwhile. Azygos veins and hemiazygos veins were both occluded in two patients. One patient had the hemiazygos vein occluded. Aortic-to-pulmonary collaterals were occluded in 6 patients in the meantime. Atrial septal defect occluders were applied in the transcatheter occlusions of azygos veins, hemiazygos veins and LSVC, except one patient with an azygos vein which was 5.5 mm in diameter. Saturation was increased from 0.78 to 0.85 through occlusion( P<0.05). The pressure of superior vena cava(SVC) did not elevate and the mean pressure of SVC was13.97mmHg and 14.22 mmHg before and after occlusion( P>0.05). No complications associated with interventional procedures occurred. There was no significant decrease in blood oxygen saturation. Facial and upper limb edema, varicose veins in the chest and abdominal wall, pleural effusion and peritoneal effusion did not happen during follow up of 2 years. Two patients underwent TCPC operation one year and five years after interventional occlusion separately. Conclusion:Transcatheter occlusion of azygos/hemiazygos vein or PLSVC was feasible in patients with complex congenital heart diseases and venous stealing after bidirectional Glenn procedure on the premise of choosing suitable indications. Suitable indications meant that the pressure of pulmonary artery and superior vena cava was less than 20 mmHg in the basal state, and the pressure of superior vena cava was also less than 20 mmHg before the release of the occluder. Occlusions may increase the oxygen saturation of patients, improve the quality of life, and even promote the development of pulmonary vascular bed, so as to achieve the indications of TCPC operation in some patients.

Objective:To investigate the mechanism of neurofibromin 1 (NF1) in gallbla-dder cancer.Methods:The experimental study was conducted. Human gallbladder cancer cell lines, including GBC-SD, NOZ, SGC996, EH-GB1, ZJU0428, human embryonic kidneys cell line 293T and human cervical cancer cell line HELA, were cultured. The recombinant plasmids (mRFP-YAP1 FL-FLAG and eGFP-MYC-NF1 2650?2750-HA) were constructed for co-immunoprecipitation experiment. The truncated Yes associated protein 1(YAP1) and NF1 recombinant proteins were purified in vitro. The interaction between NF1 and YAP1 in vitro or in vivo were verified by isothermal titration calori-metry (ITC) assay, GST pull-down experiment, co-immunoprecipitation, immunofluorescence, laser confocal microscopy, and the expression of NF1 protein in different gallbladder cancer cell lines was verified by Western blot experiments. Observation indicators: (1) interaction between NF1 and YAP1 in vitro; (2) interaction between NF1 and YAP1 in cells; (3) expression of NF1 protein in different human gallbladder cancer cell lines. The dissociation constants were exported from ITC 200 software and represented as Mean± SD. Count data were represented as absolute numbers. Results:(1) Interaction between NF1 and YAP1 in vitro. ① Results of ITC assay showed that there was interac-tion between PPQY and YAP1-WW1, between PPQY and YAP1 (Amino acid residues 162?275), and the dissociation constants between PPQY and YAP1-WW1, between PPQY and YAP1(Amino acid residues 162?275) were (0.42±0.06)mmol/L, (0.69±0.14)mmol/L, respectively. ② GST pull-down results indicated that the target protein His-Sumo-YAP1 WW1 was obviouly observed in protein lane of reaction system between GST-PPQY recombinant protein and His-Sumo-YAP1 WW1, relative to the reaction system between GST protein and His-Sumo-YAP1 WW1. The target protein His-Sumo-YAP1 WW2 was obviouly observed in protein lane of reaction system between GST-PPQY recombinant protein and His-Sumo-YAP1 WW2, relative to the reaction system between GST protein and His-Sumo-YAP1 WW2. (2) Interaction between NF1 and YAP1 in cells. ① Co-immunoprecipitation results indica-ted that NF1 protein was observed in cell lysis solution which was incubated by FLAG gel beads and cotransfected with mRFP-YAP1 FL-FLAG and eGFP-MYC-NF1 2650?2750-HA. ② Immuno-fluorescence and laser confocal microscopy results indicated that YAP1 and NF1 with obvious fluorescence were co-localized in the cytoplasm of human gallbladder cancer NOZ cells. However, YAP1 with obvious fluorescence was localized in the nucleus of human gallbladder SGC996 cells and NF1 showed weak fluorescence. (3) Expression of NF1 protein in different human gallbladder cancer cell lines. Western blot results showed that with the expression level of NF1 protein in HELA cell line as the standard, the relative expression levels of NF1 protein in EH-GB1, GBC-SD, NOZ, SGC996, ZJU0428 cell lines were 1.28, 0, 1.01, 0, 0, respectively. Conclusion:NF1 affects the gallbladder cancer by directly acting on YAP1 protein.

The unique characteristics of the tumor microenvironment (TME) could be exploited to develop antitumor nanomedicine strategies. However, in many cases, the actual therapeutic effect is far from reaching our expectations due to the notable tumor heterogeneity. Given the amplified characteristics of TME regulated by vascular disrupting agents (VDAs), nanomedicines may achieve unexpected improved efficacy. Herein, we fabricate platelet membrane-fusogenic liposomes (PML/DP&PPa), namely "platesomes", which actively load the hypoxia-activated pro-prodrug DMG-PR104A (DP) and physically encapsulate the photosensitizer pyropheophorbide a (PPa). Considering the different stages of tumor vascular collapse and shutdown induced by a VDA combretastatin-A4 phosphate (CA4P), PML/DP&PPa is injected 3 h after intraperitoneal administration of CA4P. First, CA4P-mediated tumor hemorrhage amplifies the enhanced permeation and retention (EPR) effect, and the platesome-biological targeting further promotes the tumor accumulation of PML/DP&PPa. Besides, CA4P-induced vascular occlusion inhibits oxygen supply, followed by photodynamic therapy-caused acute tumor hypoxia. This prolonged extreme hypoxia contributes to the complete activation of DP and then high inhibitory effect on tumor growth and metastasis. Thus, such a combining strategy of artificially-regulated TME and bio-inspired platesomes pronouncedly improves tumor drug delivery and boosts tumor hypoxia-selective activation, and provides a preferable solution to high-efficiency cancer therapy.
