Neural and brain imaging has become one of the most challenging subjects and attracted more attentions. Neural and brain imaging can quantify morphological pattern, structure and function of brain and nerve system, which offers us not only a deeper understanding of brain and nerve system, but also improved effectiveness of clinical diagnosis and treatment of diseases. Optical Coherence Tomography (OCT) is a new imaging technique and has been widely used in areas of biology and medicine. Study on OCT technique applying to neural and brain imaging has drawn special attention and rapid developments have been achieved. The technique provides new ideas and methods to solve problems in neural and brain imaging and its potential needs to be discovered. This article re-views the latest techniques and development in OCT for neural and brain imaging. Advantages and disadvantages of the technique and foreground of the development are discussed.

BACKGROUND: Atrial natriuretic peptide (ANP)-synthesizing cells distribute in all over the body. However, very little is known about the morphological localization and the distribution characteristics of ANP-synthesizing cells in different regions of rat stomach. OBJECTIVE: To investigate the ultrastructural localization and distribution characteristics of ANP-synthesizing cells in rat stomach. DESIGN: Repeated measurement experiment. SETTING: Chengde Medical Collage, Chengde, Hebei Province, China. MATERIALS: This study was performed at the Laboratory for Institute of Chinese Materia Medica Immunology (provincial key laboratory), Chengde Medical College between October 2004 and July 2007. Eighteen adult Wistar rats of either gender, weighing 175-300 g, were provided by the Laboratory Animal Center of Chengde Medical College. The disposal of animals was conducted in accordance with ethical guidelines for the use and care of animals. ANP antibody and serum (Santa Cruz Biotechnology, Inc, USA), Protein A-15 nm colloidal gold labeled (Sino-American Biotechnology Company, China), CMIAS image analysis system (Beijing University of Aeronautics and Astronautics, China) and JEM-1200EX transmission election microscope (Japan) were used in the study. METHODS: After gastric and right atrial tissues (as a positive control in immanohistochemical staining for ANP-synthesizing cells) were fleshly excised from anesthetized Wistar rats, the specimens were longitudinally harvested along rat gastric cardiac region, gastric fundic mucosa and gastric pyloric region. Gastric tissue was performed immunohistochemical staining (for positive control) together with right atrial tissue, to observe the distribution characteristics of ANP-synthesizing cells in different regions of rat gastric tissue, and to localize ANP-synthesizing cells. The ultrastructural localization of ANP-synthesizing cells in the rat gastric mucosa was performed by postembedding immunoelectron microscopy. The area-density percentage of ANP-synthesizing cells in the different regions of rat stomach (gastric cardiac region, pyloric region and fundic region) was calculated with a CMIAS image analysis system. MAIN OUTCOME MEASURES: Morphological appearance and localization of ANP-synthesizing cells as well as the different area-density percentage in different regions of rat stomach. RESULTS: As a positive control, ANP-synthesizing cells showed intense positive expression in atrial myocytes and cytoplasm and in gastric mucosa (mainly within the lower third of rat gastric mucosa). The morphological appearance of the individual ANP-synthesizing cell was variable, exhibiting round, pyramidal and flask shapes. Negative staining for ANP-synthesizing cells was detected in the lamina propria, submucosa, and smooth muscle. ANP-synthesizing cells existed in different regions of rat stomach and its area-density was the largest in the pyloric region. The distribution order of ANP-synthesizing cells in area-density was gastric cardiac region > gastric pyloric region > gastric fundic mucosa in mucosa layer. CONCLUSION: ANP-synthesizing cells mainly exist within the lower third of the rat gastric mucosa. The percentage of area-density of ANP-synthesizing cellswas variable in different regions of rat gastric mucosa, and its percentage of area-density was the largest in the gastric cardiac region.

Objective:To investigate effect of curcumin on serum gelatinases level in patients with unstable angina pectoris (UAP). Methods:A total of 80 UAP patients admitted from January 2010 to September 2010 were enrolled and randomly divided into curcumin treatment group (n=40) and routine treatment control group (n=40). Serum levels of gelatinases [contain matrix metalloproteinase (MMP)-2 and -9] of the two groups were measured before and 30d after treatment.Results: Compared with before treatment , after treatment, serum levels of gelatinases significantly decreased [MMP-2:(52.64±6.77)ng/ml vs.(32.65±1.67)ng/ml,MMP-9:(56.75±7.34)ng/ml vs.(35±1.88)ng/ml]in curcumin treatment group (P<0.01), and they were significantly lower than those of routine treatment control group[MMP-2:(32.65±1.67)ng/ml vs.(37.78±2.76)ng/ml,MMP9:(35±1.88)ng/ml vs.(40.23±1.95)ng/ml]],P<0.05. Conclusion:Curcumin could decrease serum levels of gelatinases in patients with unstable angina pectoris, and possesses effect stabilizing coronary artery plaque.

Objective To investigate relationship between the expressions of TGF-β1 mRNA, Smad7 mRNA and ki-67 mRNA and the clinicopathologic characteristics in gastric carcinoma. Methods 60 cases with gastric carcinoma tissue and 20 cases with normal gastric tissue, which were surgically removed and certified by pathology, were collected. The expressions of TGF-β1 mRNA, Smad7 mRNA and ki-67 mRNA were detected by RT-PCR in normal and carcinomatous gastric tissue. Results The expressions of TGF-β1 mRNA, Smad7 mRNA and ki-67 mRNA in normal gastric tissue were lower than those in carcinomatous gastric tissue (P < 0.05). The expressions of TGF-β1 mRNA, Smad7 mRNA and ki-67 mRNA in gastric carcinoma which were well differentiated and moderately differentiated were significantly lower than those in poorly differentiated gastric carcinoma (P<0.05). The expressions of TGF-β1 mRNA, Smad7 mRNA and ki-67 mRNA in gastric carcinoma without lymph node metastasis were lower than those in gastric carcinoma with lymph node metastasis. The expressions of TGF-β1 mRNA, Smad7 mRNA and ki-67 mRNA in Ⅰ+Ⅱ stage were lower those in Ⅲ+Ⅳ stage (P < 0.05). Linear correlation showed there were positive correlations among TGF-β1 mRNA, Smad7 mRNA and ki-67 mRNA in gastric carcinoma. Conclusions The canonical TGF-β1 Smad7 and Ki-67 mRNA play a role in the carcinogenesis, development, differentiation of gastric carcinoma.
