Objective To investigate the diagnosis and treatment in patients with acute myocardial infarction (AMI) and complicated left ventricular wall rupture (LVWR). Methods A retrospective analysis was made on the clinical features, diagnosis and successful treatment in three AMI patients with LVWR from December 2015 to April 2016. Results Three cases were included in this study. Case 1, the mesh like cardiac rupture after AMI was diagnosed by ultrasonic Doppler. Emergency revascularization was performed due to the combined cardiac shock, and the infarct related artery was opened. The vasoactive drugs were used after revascularization to reduce ventricular pressure load and volume load in the haemodynamic monitoring, and anticoagulation, antiplatelet agents were less used or discontinued to promote local thrombus healing of ventricular rupture. Case 2 was a recurrent myocardial infarction patient. LVWR was diagnosed by ultrasonic Doppler one day after emergency operation. The ruptured ventricular wall was encapsulated by thrombus. The drug therapy was effective in hemodynamic monitoring. LVWR was further confirmed by cardiac CT after clinical stabilization. Case 3 was diagnosed LVWR by ultrasonic Doppler four days after AMI. Because the ruptured ventricular wall was limited by incompletely organized thrombus, and the haemodynamic condition was stable, selective surgical repair of rupture after coronary angiography was performed. Conclusion The effective drug therapy combined with percutaneous coronary intervention and surgical repair can reduce the risk of death in patients with LVWR after AMI.

Objective:
: Kinesin family member C1 (KIFC1), a non-essential kinesin-like motor protein, has been found to serve a crucial role in supernumerary centrosome clustering and the progression of several human cancer types. However, the role of KIFC1 in glioma has been rarely reported. Thus, the present study aimed to investigate the role of KIFC1 in glioma progression.
Methods:
: Online bioinformatics analysis was performed to determine the association between KIFC1 expression and clinical outcomes in glioma. Immunohistochemical staining was conducted to analyze the expression levels of KIFC1 in glioma and normal brain tissues. Furthermore, KIFC1 expression was knocked in the glioma cell lines, U251 and U87MG, and the functional roles of KIFC1 in cell proliferation, invasion and migration were analyzed using cell multiplication, wound healing and Transwell invasion assays, respectively. The autophagic flux and expression levels matrix metalloproteinase-2 (MMP2) were also determined using imaging flow cytometry, western blotting and a gelation zymography assay.
Results:
: The results revealed that KIFC1 expression levels were significantly upregulated in glioma tissues compared with normal brain tissues, and the expression levels were positively associated with tumor grade. Patients with glioma with low KIFC1 expression levels had a more favorable prognosis compared with patients with high KIFC1 expression levels. In vitro, KIFC1 knockdown not only inhibited the proliferation, migration and invasion of glioma cells, but also increased the autophagic flux and downregulated the expression levels of MMP2.
Conclusion
: Upregulation of KIFC1 expression may promote glioma progression and KIFC1 may serve as a potential prognostic biomarker and possible therapeutic target for glioma.
