  • REGULATION OF microRNA IN OSTEOBLAST DIFFERENTIATION AND ITS CLINICAL SIGNIFICANCE

    Objective To summary the functional roles and molecular mechanisms of microRNA (miRNA) in osteoblast differentiation so as to supply information for basic and cl inical researches. Methods Recent l iterature concerning miRNA in osteoblast differentiation was reviewed. The information was classified and summarized. Results miRNAs critically regulate bone morphogenetic protein, transforming growth factor β, and Wnt/β-catenin signal ing pathways during osteoblast differentiation. In pathological conditions, especially in some disorders of abnormal osteoblast differentiation, downregulated miRNA expression has been observed. Conclusion miRNA may represent a novel biomarker for diagnosis, and a candidate target therapies for the disorders with abnormal osteoblast differentiation.

  • Clinical study of 17 patients with ex vivo liver resection followed by autotransplantation for advanced hepatic alveolar echinococcosis in high altitude area

    ObjectiveTo summarize short-term and long-term effects of ex vivo liver resection followed by autotransplantation (Abbreviation: autotransplantation) in treatment of advanced hepatic alveolar echinococcosis (HAE).MethodThe clinical data and follow-up data of 17 patients with advanced HAE who underwent autotransplantation from November 2016 to July 2019 in the Ganzi Tibetan Autonomous Prefecture People’s Hospital were retrospectively analyzed.ResultsThe autotransplantations were performed successfully in the 17 patients with advanced HAE. Ten patients underwent the inferior vena cava (IVC) reconstruction with autologous saphenous veins, 5 patients underwent the artificial revascularization, 1 patient underwent the direct anastomosis of the original IVC, and 1 patient didn’t reconstructed (the retroperitoneal collateral circulation was abundant). The mean liver graft mass was 681.3 g (365–1 350 g) and operation time was 11.5 h (9–16 h). The median anhepatic period was 312 min (175–450 min), blood loss was 2 000 mL(950–4 500 mL), red blood cell suspension transfusion was 6.4 U (1–20 U), and fresh frozen plasma was 1.1 L (0.8–2.0 L). The postoperative hospital stay was 5 to 45 d with an average of 25.6 d. There were 4 patients with the postoperative hepatic enveloping effusion, 1 patient with bile leakage, and 1 patient with bile duct stenosis. All of them were treated and cured, and no death occurred. The follow-up time of 17 patients was 3 to 35 months with an average of 9.5 months, no recurrence of HAE and distant metastasis were observed.ConclusionsIn highlands, autotransplantation in treatment of advanced HAE patients with different IVC reconstruction is satisfactory, but it has a higher risk and is difficult. Choice of intraoperative reconstruction materials, judgment of posterior peritoneal collateral circulation, presence or absence of tension in end-to-end anastomosis of the IVC require precise consideration. At the same time, anticoagulation therapy and complications management are difficult, and it is only suitable for plateau medical center with rich experience.
