Neuroendocrine tumors of the epiglottis were extremely rare. Patients normally had no obvious symptoms and signs of early stage. Epiglottis lingual except (without) tubercle of epiglottis, and hyperplastic mass were observed by using laryngoscopy and also confirmed by biopsy and immunohistochemistry. Immunohis- tochemical studies showed that Syn, a broad spectrum endocrine marker, and CgA, a specific marker of endocrine tumor, were both positive. Which is consistent with the diagnosis of neuroendocrine carcinoma.

Objective To detect the expression of metallothionein-3 (MT-3)mRNA in human esophageal squamous cell carcinoma. Methods Five cell lines of human esophageal cancer,TE-1,TE-13,TTN,ECA-109 (cell lines of esophageal squamous cell carcinoma) and OE33 (cell lines of esophageal adenocarcinoma),were used in this study. RT-PCR was employed to detect the expression of MT-3 mRNA. Peripheral blood monouclear cells from normal subjects were served as controls. Results Sequencing of RT-PCR product certified the gene of MT-3 mRNA. It was revealed by gel electrophoresis that there was expression of MT-3 mRNA in each cell line. The relative expression of MT-3 mRNA was 0.230?0.023,0.516?0.020,0.140?0.009,0.176?0.015 and 0.085?0.011 in cell lines of TE-1,TE-13,TTN,ECA-109 and OE33,respectively,significantly lower than that in controls (0.762?0.026) (P

To improve the yield of industrial fermentation, a method based on near infrared spectroscopy was presented to predict the growth of yeast.The spectral data of fermentation sample were measured by Fourier-transform near-infrared (FT-NIR) spectrometer in the process of yeast culture.Each spectrum was acquired over the range of 10000-4000 cm1.Meanwhile, the optical density (OD) of fermentation sample was determined with photoelectric turbidity method.After that, a method based on competitive adaptive reweighted sampling (CARS) was used to select characteristic wavelength variables of NIR data, and then extreme learning machine (ELM) algorithm was employed to develop the categorization model about the four growth processes of yeast.Experimental result showed that, only 30 characteristic wavelength variables of NIR data were selected by CRAS algorithms, and the prediction accuracies of training set and test set of the CARS-ELM model were 98.68% and 97.37%, respectively.The research showed that the near infrared spectrum analysis technology was feasible to predict the growth process of yeast.

As tremendous genomic data avalanches, exploring biological mechanism by data analysis and theory methods has become important for theoretical biology research. This method is significant for the study of complex gene functions and gene networks. Bowers used higher order logic relationships to decipher protein network organization, which is a systemic method called logic analysis of phylogenetic profiles (LAPP). LAPP is a data modeling and different from traditional computational methods. This computational approach identifies logic relationships of the elements (or components) in complex networks through the logic analysis of their expression data. The method can be used to infer functional relationships of two associated proteins to one another. It is important for discovering the new function mechanism of the protein. The clusters of orthologous groups (COGs) involved in a gene network usually are large groups and therefore LAPP is also an approach for complex gene logic networks. After the establishment of the gene logic network, it is convenient for the regulation of gene through the network. The method can used in many fields, such as species evolution, oncologic diagnosis and so on. LAPP was systematically described and analyzed and recent developments in methodologies and applications were highlighted. Some opinions of them were also given.

OBJECTIVE:To provide evidence for rational use and clinical monitoring of Alprostadil lipid-micro injection (Li-po-PGE1). METHODS:Adult inpatients receiving Lipo-PGE1 from hospital information system(HIS)of 159 hospitals were select-ed as research subject. Based on frequency statistics,population,clinical diagnosis,and average daily dose of Lipo-PGE1 were all studied. RESULTS:A total of 71687 adult inpatients were included,and the male was more than female,mostly aged 61-75. The hospitalization duration was 8-14 d(45.01%),most of patients were recovered(68.20%). Lipo-PGE1 was wildly used in the clin-ic,and was used for 871 kinds of clinical diseases in total;top 3 diseases were cerebral infarction(9.06%),non-insulin dependent diabetes mellitus (8.65%) and chronic ischemic heart disease (8.08%). The average daily dose of different diseases and different hospitals were significantly different,mostly≤12.5μg. CONCLUSIONS:As adjuvant drug,medical institutions and related super-vision departments should formulate reasonable monitoring index and strengthen medication guidance and evaluation of Lipo-PGE1.

Objective To study the CT perfusion features of various lymph nodes in the neck.Methods Dynamic perfusion CT scanning was performed in 83 neck lymph nodes proved by pathology,including tuberculosis lymph nodes, lymphoma and metastatic lymph nodes. The shapes, blood flow modes,and perfusion parameters of these lymph nodes were compared among 3 groups. Statistical analysis of L/T and CT perfusion parameters was performed by one-way ANOVA and LSD test. Results The values of MTT of tuberculosis lymph nodes, lymphoma and metastatic lymph nodes were (28. 13 ±5.08), (31.08 ±5.82),and ( 11.24 ±5.31 ) s,respectively. The MTT of metastatic lymph nodes was statistically lower than that of tuberculosis lymph nodes and lymphoma (P ＜ 0. 05). Their frequencies of marginal blood flow were 5/9,4/19, and 39/55 (70. 9% ), respectively. The frequency of marginal blood flow in the tuberculosis lymph nodes and metastatic lymph nodes was statistically higher than that of lymphoma ( P ＜ 0. 05 ). Their frequencies of central blood flow were 2/9, 11/19, and 9/55 (16.4%), respectively. The frequency of central blood flow in the lymphoma was statistically higher than that of tuberculosis lymph nodes and metastatic lymph nodes ( P ＜ 0. 05 ). Their values of L/T were 1.82 ± 0. 32, 1. 80 ± 0. 39, and 1.84 ± 0. 36,(40. 98 ±6. 62) s,respectively. There were no significant differences in L/T, BF, BV and TTP among tuberculosis lymph nodes, lymphoma and metastatic lymph nodes( P ＞ 0. 05 ). Conclusion CT perfusion,especially combination functional imaging with perfusion images may be helpful in judging the nature of neck lymph nodes.
