The design theories of modern nuclear technologies usually rely on modern electro-magnetic field theories using ANSYS and NUCLEUS softwares to implement on PCs. However, the Western House Nuclear Industry Foundation Project ID 0002425010-FengAn requests me to give a illustration about how to do energy conversions inside a typical two-and-a-half-sta...

In contemperary world, Channel Contruction & Mineral Mining have put channel formation analysis into a very important point, The Software Dynaform can formate many kinds of channels. The Author proposes a different kind of Dynaform implementation in which the whole system can be realized in a single dynaform project. And the desired work will be fi...

Nowadays, modern astronautics require highly advanced equipment and detecting devices. The Detecting Devices ordinarily do not require EMIC (ElectroMagnetic Interference Control) check before the whole body of the testing board can be fully developed. However, we invent one kind of EMIC algorithm and implement this algorithm into a small rocket and...

To observe the effect of signal transducers and activators of transcription 3 (STAT3) gene silence on the growth of breast cancer cell line MCF7 in vitro and in vivo and discuss the feasibility and effectiveness of STAT3 used as gene therapeutic target for breast cancer. Human breast cancer cell line MCF7 cells were divided into 3 groups: mock cont...

To investigate the feasibility and safety of monopolar electrocautery shovel (ES) in laparoscopic total mesorectal excision (TME) with anal sphincter preservation for rectal cancer in order to reduce the cost of the laparoscopic operation, and to compare ES with the ultrasonically activated scalpel (US). Forty patients with rectal cancer, who under...

To explore geometrical shape deforms, stress distribution, strain distribution and wall thickness of products in the process of polycarbonate (PC) hot gas pressure bulging, numerical simulation of 1mm thick hemispherical PC part with a diameter of 100mm has been conducted by the software of DYNAFORM. The result shows that abrupt changes tend to occ...

Lymph node micrometastasis in early gastric cancer is being widely discussed. Cytokeratin (CK) staining is an important way to distinguish epithelial cancer cells. This study was to investigate the correlations of epithelial cadherin (E-cad) expression to lymph node micrometastasis, and clinicopathologic features of early gastric cancer, and to eva...

RF Ablation-Induced Cardiac Asystole. We present a case of cardiac asystole induced by radiofrequency catheter ablation of a left anterolateral accessory pathway in a 28-year-old woman with Wolff-Parkinson-White syndrome who was experiencing recurrent palpitation. Radiofrequency current applied on the ventricular aspect of the mitral annulus corres...

To investigate the effects of D-limonene (D-L) on the cell growth and apoptosis in HL-60, K562 cells and to elucidate its mechanism, the influence of D-L on proliferation of HL-60 and K562 cells was determined by propidium iodide assay, the expression levels of mutant p53, bcl-2, bax gene were detected by cell morphological analysis, flow cytometry...

AIM: To study the micrometastasis in the lymph nodes of mucosal gastric cancer. METHODS: We examined 2526 lymph nodes from 84 patients with mucosal gastric cancer. Two consecutive sections were prepared, for simultaneous staining with hematoxylin and eosin and immunostaining with CAM 5.2 monoclonal antibody against cytokeratin (CK), respectively. A...

The relation between high current atrial stimulation and antiar-rhythmic drugs was not clear. We evaluated the effects of procainamide and dl-sotalol on the electrophysiological changes induced by high current stimulation. Effects of high current atrial stimulation on effective refractory period, dispersion of refractoriness, conduction velocity, a...

To investigate the role of nuclear factor kappa B (NF-kappaB) in the pathogenesis of lung injury induced by intestinal ischemia/reperfusion (I/R), and its effect on intercellular adhesion molecule-1 (ICAM-1) expression and neutrophil infiltration. Twenty-four Wistar rats were divided randomly into control, I/R and pyrrolidine dithiocarbamate (PDTC)...

To clarify the clinicopathologic characteristics of micrometastasis in lymph nodes and microinvasion in primary lesion for the treatment options with regard to submucosal gastric cancer. 1945 lymph nodes and 68 primary tumors resected from 79 patients with submucosal gastric cancer were examined. Two consecutive sections were prepared for simultane...

To investigate the effects and mechanism of d-limonene on the growth and metastasis of gastric cancer in vivo. Metastatic model simulating human gastric cancer was established by orthotopic implantation of histologically intact human tumor tissue into gastric wall of nude mice. One percent d-limonene was orally administered at dose of 15 ml/kg ever...

To investigate the apoptosis effect induced by D-limonene on BGC-823 gastric cancer cells. The expression of p53, bc1-2 in BGC-823 cells and qualitative, quantitative index of cell apoptosis were detected with MTT, electron microscopy, flow cytometry and immunohistochemical method. D-limonene could induce the formation of apoptotic bodies in a dose...

Objectives. The purposes of this study were to evaluate the atrial electrophysiology and autonomic nervous system in patients who had paroxysmal supraventricular tachycardia (PSVT) associated with paroxysmal atrial fibrillation (PAF).Background. PAF frequently appeared in patients with PSVT. However, the critical determinants for the occurrence of...

This study investigated the difference of atrial electrophysiologic characteristics between a normal and dilated atrium and compared them among patients with paroxysmal atrial fibrillation and flutter. Twenty-seven patients with paroxysmal atrial fibrillation and 28 patients with paroxysmal atrial flutter were divided into four subgroups, according...

Objectives. This study evaluated the effect of high intensity drive train (S1) stimulation on the atrial effective refractory period (ERP) and its relation to the autonomic nervous system.Background. High intensity S1 stimulation was demonstrated to shorten the ventricular ERP and to increase dispersion of refractoriness. These effects may be due t...
