Expression and clinical significance of KIF5A in triple negative breast cancer / 国际生物医学工程杂志

Objective To investigate the expression and clinical significance of KIF5A in triple negative breast cancer tissues.Methods The clinical and pathological data of 82 patients with triple negative breast cancer who underwent breast cancer resection were retrospectively analyzed.The expression of KIF5A in cancer tissues and corresponding adjacent tissues was detected by immunohistochemistry method,and its relationship with clinicopathological features was analyzed.Results The positive high expression rate of KIF5A in triple negative breast cancer tissues was 63.4％,but low or no expression in adjacent tissues.The abnormal expression of KIFSA was correlated with the TNM stage and Lymph node metastasis (all P＜0.05),but not associated with age,tumor grade,size and vascular tumor thrombus (all P＞0.05).Survival analysis indicated that patients with high KIF5A expression in triple negative breast cancer were significantly shorter than those with low KIF5A expression (P＜0.05).Conclusions The abnormally high expression of KIF5A in triple negative breast cancer tissues is associated with high TNM and lymph node metastasis in breast cancer,and high expression of KIF5A suggests that patients with triple negative breast cancer may have poor prognosis.

Application progresses of intravoxel incoherent motion technique in liver diseases / 中国医学影像技术

Intravoxel incoherent motion (IVIM) is an new technique based on traditional DWI,which can truly separate and extract water molecules diffusion and microcirculation perfusion pseudo-diffusion,and choose multi-b-value and bi-exponential model to obtain DWI.It can reflect the relationship between signal attenuation within the voxel and b values.Nowadays,IVIM DWI has been widely used in the studies of liver diseases.In this article,the recent progresses of MRIVIM in liver imaging were reviewed.

Analysis of Clinical Response on Cardiac Resynchronization Therapy in Patients of Chronic Heart Failure With Different QRS Wave Morphology / 中国循环杂志

Objective: To explore the clinical response on cardiac resynchronization therapy (CRT) in patients of chronic heart failure (CHF) with different QRS wave morphology. Methods: A total of 52 CHF patients received CRT in our hospital and the Seventh People's Hospital of Zhengzhou City from 2010-03 to 2013-07 were retrospectively studied. The patients were divided into 3 groups: True-complete left bundle branch block (t-CLBBB) group,n=20, Classic LBBB (CLBBB) group,n=15 and IVCD group,n=17. The general clinical condition, the indexes of echocardiography at 6 months of follow-up study including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), NYHA classiifcation and 6-MWT were examined and compared among different groups. Results: In general clinical condition, the ratio of non-ischemic heart disease patients in t-CLBBB group was higher than those in CLBBB group and IVCD group, allP<0.05. By 6 months follow-up study, LVEDD in t-CLBBB group (62.6 ± 8.9) mm was lower than those in CLBBB group (70.0 ± 8.9) mm and IVCD group (72.8 ± 8.0) mm, LVEF was higher in t-CLBBB group (38.5 ± 6.2) % than those in CLBBB group (31.7 ± 6.7) % and IVCD group (30.1 ± 6.7) %. NYHA classiifcation in t-CLBBB group (2.00 ± 0.45) grade was lower than those in CLBBB group (2.73 ± 0.80) grade and IVCD group (3.12 ± 0.78) grade . 6-MWT in t-CLBBB group (302.0 ± 57.9) m was longer than those in CLBBB group (257.3 ± 59.0) m and IVCD group (220.2 ± 57.9) m, allP<0.05. Conclusion: CRT is an effective method for treating CHD patients, different QRS morphology may have different response, the patients with t-CLBBB would make better response.

Short-term Effect of Thrombus Aspiration Catheters Combining Tirofiban Medication for Myocardial Tissue Reperfusion Recovery in Patients With Acute ST-elevation Myocardial Infarction / 中国循环杂志

Objective: To evaluate the short-term effect of thrombus aspiration catheters combining tiroifban medication for myocardial tissue reperfusion recovery in patients with acute ST-elevation myocardial infarction (STEMI). Methods: A total of 105 STEMI patients with percutaneous coronary intervention (PCI) in our hospital from 2011-05 to 2013-05 were studied, there were 73 male and 32 female with the mean age of (58.39 ± 10.37) years. The patients were randomly divided into 2 groups, Group A, the patients received thrombus aspiration catheters with intravenous tiroifban, n=53 and Group B, the patients received tiroifban and PCI, n=52. The basic clinical features, myocardial tissue perfusion level, major adverse cardiovascular events (MACE) at post operative and in-hospital period were recorded, the cardiac function was examined by echocardiography at 6 months after PCI in both groups. Results: The basic clinical features were similar between 2 groups. The thrombolysis in myocardial infarction trial (TIMI) 3 lfow rate was higher in Group A than that in Group B (92.45% vs 55.77%), P=0.000. TIMI 2 and TIMI 0~1 lfow rates were lower in Group A than that in Group B (7.55%vs 26.92%), P=0.008 and (0%vs 17.31%), P=0.002. The adjusted TIMI frame was lower in Group A (27.26±5.50) vs (38.98±5.42), P0.05. Conclusion:Thrombus aspiration catheters combining tiroifban medication may obviously improve the myocardial tissue reperfusion and the short-term cardiac function in STEMI patients after PCI, it could reduce the incidence of no-relfow without increasing MACE.
