Chinese Journal of Clinical Oncology 2015;(9):487-490
Thyroid cancer is the most common malignant tumor of the human endocrine system. A papillary thyroid microcarci-noma (PTMC) is usually defined as a papillary thyroid tumor that is less than 10 mm in diameter. The incidence of thyroid cancers has obviously increased in recent years. The surgical treatment of PTMC differs in China and overseas. Aside from conventional surgery, novel surgical methods, such as ultrasound-guided percutaneous ablation, have been used for the surgical treatment of PTMC. This arti-cle mainly discusses the research progress in the surgical treatment of PTMC.

6.Umbilical cord blood mononuclear cell transplantation is safe for treatment of coronary heart disease with heart failure
Chinese Journal of Tissue Engineering Research 2013;(49):8557-8562
BACKGROUND:Number of experimental and clinical studies have shown that stem celltransplantation can establish new blood vessels and improve heart function instead of necrotic myocardium, to significantly improved clinical symptoms and prognosis of cardiovascular disease patients.
OBJECTIVE:To observe the safety of human umbilical cord blood mononuclear cells transplantation in patients with coronary heart disease and heart failure.
METHODS:A total of 12 patients with coronary heart disease and heart failure (acute myocardial infarction and heart failure in six cases, old myocardial infarction and heart failure in six cases) were enrol ed in this study. Patients were treated on the basis of standard medication and percutaneous coronary intervention. The coronary pathway was established via a percutaneous catheter, and suspension of cord blood mononuclear cells was injected through microcatheter into the distal artery. Routine blood test was carried out at 1 week after celltransplantation, blood routine, liver function, kidney function, C-reactive protein, IgA, IgG were compared preoperatively and postoperatively.
RESULTS AND CONCLUSION:The incidence of adverse reactions in cord blood stem celltransplantation was 8.3%, including one case of fever. No micro-embolism occurred. During 1-week fol ow-up, no graft-versus-host disease appeared. After celltransplantation, there were no significant changes in blood routine, liver function, kidney function, C-reactive protein, IgA, IgG. These findings indicate umbilical cord blood monomuclear cells transplantation is safe in a short term for patients with coronary heart disease and heart failure.
7.Intracoronary transplantation of autologous peripheral blood stem cells in old patients with acute myocardial infarction:5-year postoperative evaluation of cardiac function
Chinese Journal of Tissue Engineering Research 2014;(1):125-130
BACKGROUND:Myocardial infarction patients commonly appear to have left ventricular remodeling and heart failure. Because of physical characteristics, these two complications are more likely to occur in elderly patients with myocardial infarction. In recent years, stem celltransplantation in the treatment of acute myocardial infarction and heart failure has become a hot topic, and the feasibility and safety has been confirmed, but its long-term outcomes in elderly patients are stil unclear.
OBJECTIVE:To assess the long-term effect of transplantation of autologous peripheral blood stem cells on the left ventricular remodeling and heart function in the old patients with myocardial infarction.
METHODS:Thirty old patients (age ≥ 60 years) with myocardial infarction were randomly assigned to receive intracoronary transplantation of peripheral blood stem cells fol owing bone marrow cells mobilization by granulocyte colony-stimulating factor ( 300-600μg per day) subcutaneously for 5 days in addition to conventional therapy (standard drug therapy and percutaneous coronary intervention;transplantation group, n=15) or standard therapy (standard drug therapy and percutaneous coronary intervention;control group, n=15) . Complications during intervention, left ventricular function and left ventricular remodeling at baseline and 6, 12, 24, 60 months after treatment were monitored.
RESULTS AND CONCLUSION:Left ventricular function, left ventricular end diastolic volume, and left ventricular end-systolic volume were significantly improved 6,12, 24, 60 months after autologous peripheral blood stem celltransplantation compared to baseline, while these parameters remained unchanged in the control group. These parameters had statistical difference between the two groups after treatment. During the fol ow-up, no severe side effects were observed. These findings indicate that autologous peripheral blood stem celltransplantation leads to significant and longstanding improvements in left ventricular performance of old patients with myocardial infarction, and shows good safety.

Chinese Journal of Tissue Engineering Research 2012;16(1):99-102
BACKGROUND: Transplantation of the human umbilical cord blood mononuclear cells (HUCBCs) have received increasing attention, as a promising candidate for the cellular transplantation, but the majority of the existing studies are basic research.OBJECTIVE: To report a patient of extensive anterior-wall acute myocardial infarction with cardiogenic shock and severe heart failure, after treatment of HUCBCs transplantation. METHODS: A 73-year-old female patient with cardiogenic shock and severe heart failure after extensive anterior-wall acute myocardial infarction was treated with percutaneous coronary intervention (three scaffolds implantation) and medications, and she still appeared the symptoms of congestive heart failure, such as severe recurrent dyspnea. 2.4 × 108 HUCBCs (50 mL cell suspension) was injected into the infarcted myocardium through the left anterior descending artery by using coronary micro-guide catheter.RESULTS AND CONCLUSION: The patient reported profound clinical benefit including improvement of heart-failure-associated symptoms after the transplantation. Notably the patient did not experience the cell transplant-related side effects during 4 months of follow-up. The ejection fraction increased from 22% before the transplantation to 53% at 21 days after the transplantation. The B-type natriuretic peptide decreased from 1 730 ng/L before the transplantation, 854 ng/L after the transplantation to 264 ng/L at 21 days after the transplantation. The patient did not appear the symptoms of congestive heart failure, including dyspnea, chest distress and hypodynamia, she returned to daily activity at 4 months of follow-ups. Experimental findings indicate that the HUCBCs transplantation is an effective and safe means for patients cardiogenic shock and severe heart failure after acute myocardial infarction.

10.AN EXPERIMENTAL STUDY OF LIVINGBCG'S EFFECT ON THE KILLING AND DIGESTIVE ABILITIES OF RABBIT ALVEOLAR MACROPHAGE LYSOSOME TO LIVING-YEAST
Acta Anatomica Sinica 1953;0(01):-
By means of the observation of acridine orange-stained lysosomes with fluorescence microscope, we studied the intracellular killing and digestive process after alveolar macrophage (AM) ingested living-yeast. Based on the morphological changes of the cells, we divided the process into three stages: the pre-phagosome-lysosome fusion stage, the phagosome-lysosome fusion and killing stage, and the digestive stage. The results revealed that all the values of phagocytic index, phagocytic rate, fusion index and fusion rate of the isolated AM of rabbits infected with living-BCG were higher than those of normal rabbits (P
