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.

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.

Objective This study was designed to evaluate the short-term effect and safety of 80 mg/d atorvastatin treating on ACS patients with interventional therapy in China. Methods From August 2002 to March 2014,1746 ACS patients accepting 80mg/d atorvastatin treatment were enrolled from three province hospital. All patients were divided into three groups, 886 patients in group A with 80mg/d atorvastatin treating for 4 weeks, 562 patients in group B with 80mg/d atorvastatin treating for 8 weeks, and 298 patients in group C with 80mg/d atorvastatin treating for 12 weeks after discharge. Blood lipid level, hepatic function, renal function and creatine kinase level were tested on 4th, 8th, 12th week. Results The percentage of patients reacting lipid levels was 85.0%in group A, 86.1%in group B, 94.0%in group C and 86.9%in total. The rate of ALT/AST exceed two times of normal upper level in group A was 1.6%, in group B was 1.8%and in group C was 1.0%.The symptom of joint and muscle pain in group A was 6.3%, group B was 1.4%, group C was 2.7%. The elevation of creatine kinase in group A was 0.8%, in group B was 0.5%, and 0%in group C. The symptom of abdomen discomfort in group A was 2.3%, group B was 2.5%and group C was 4.0%. The complaint of other symptoms was 3.2%in group A, 2.1%in group B, 1.7%in group C. Conclusions Accepting 80 mg/d atorvastatin treating for ACS patients with interventional therapy is effective and safe in short term.

Objective To observe the effect of ulinastatin on NT -proB -NP and Picco in patients with severe sepsis.Methods 50 patients with severe sepsis were randomly divided into the control group and observation group,25 patients in each group.The control group received the routine treatment,and the observation group received ulinastatin additionally.The venous blood was collected to determine cTn -I,NT -proBNP,TNF -αand Lac before treatment and 7 days after treatment.The APACHE Ⅱ and CFI were observed before treatment and 7 days after treat-ment.Results The differences of CFI,cTnI,NT -proBNP in the two groups before treatment were not significant (t =0.419,0.321,0.335,all P >0.05),after treatment,cTnI and NT -proBNP decreased more significantly(t =2.976,2.910,all P <0.05),while lifting more apparent CFI[(3.98 ±0.95)vs.(2.39 ±0.85),t =6.237,P <0.05]in the observation group than in the control group.The differences of TNF -αand Lac in the two groups before treatment were not significant (t =0.602,0.848,all P >0.05 ),after treatment,TNF -αand Lac decreased significantly faster in the observation group than in the control group(t =8.478,3.104,all P <0.05).After treat-ment,APACHE Ⅱ score decreased significantly in observation group than in the control group(t =2.321,P <0.05). Conclusion Ulinastatin had protective effects on heart function in patients with severe sepsis.

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.

Exosome is a sort of vesicle structure attached to cell membrane and released by cells, which contains numerous bioactive molecules, such as proteins, lipids, mRNA, microRNA and DNA fragments. These bioactive molecules are involved in the regulation of many biological processes, not only the participation in the occurrence and development of diverse diseases, but also the close relationship with the invasion and metastasis of tumors. The recent study has indicated that lots of exosomes released from cancer cells participate in a variety of pathological processes as a messenger of cell functions. This article will elaborate the function and application of exosomes in some malignant cancers.

Objective To investigate the changes and the significance of the contents in matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in plasm of patients with intracerebral hemorrhage (ICH). Methods The contents of MMP-2 and MMP-9 in plasm of 50 patients with ICH and 50 healthy people (control group) were measured respectively through ELISA methods. Results Compared with the control group,the increase of the contents of MMP-2 and MMP-9 had obvious statistic significance in plasm of patients with ICH (P0.05),but they had obvious statistic significance in the comparison among other time groups (P
