Endocrine-paracrine (EP) cells, also known as APUD or neuroendocrine cells, have been known to exist in the mammalian genito-urinary system. A fairly common localization is in the prostate and urethra. In this study we demonstrated for the first time the presence of small number of EP cells in the dissociated epithelial cells of the seminal vesicles of the guinea pig. The EP cells exhibited yellow FIF, while a few green or yellow-green FIF cells can be observed after L-dopa treatment. They were stained positive by the Masson-Fontana's method but consistently negative with the Grimelius silver methods indicating that they were of argentaffin nature or other paracrine cells.

Objective To study the serum gastrin levels of mothers and neonates via vaginal delivery and cesarean section. Methods The serum gastrin concentrations of 60 women underwent vaginal delivery and elective cesarean section, and the umbilical serum gastrin concentrations of neonates delivered via vagina (20 cases) and cesarean section (22 cases) were measured by radioimmuno assay. Results The serum gastrin concentrations of women in labor(108.23?24.39) ng/L were significantly higher than that of women during cesarean section( P

Objective To investigate the immune changes of interleukin-6(IL-6) of placentae and amnion in severe pregnancy-induced hypertension(PIH) and fetal growth retardation(FGR). Methods Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect IL-6 mRNA levls of placentae and amnion. Results The level of IL-6 mRNA in placentae and amnion in severe PIH group (0.71?0.07,0.81?0.02) are significantly lower than those in normal group(P0.05). Conclusions IL-6 is involved in the immune injury in severe PIH. The decreased levels of IL-6 in placentae and amnion may be the cause of fetal growth retardation

After discussing the reason for insufficiency of committee member in current ethical review , and considering the requirement for improving the function of Ethics Review Committee , this paper proposes that Ethics Review Committee should appoint more non -affiliated scientific members to ensure the independence of ethical re-view , thus protecting the rights and beneficence of subjects , and to secure the justice in ethical review of protocols , the paper also discussed the resolutions to address the challenge brought by appointing non -affiliated members .

Objective To explore the curative effect of prealbumin (PA) in the hand-foot-and-mouth dis-ease and analysis its value in monitoring and prognosing this disease. Method Detect levels of serum PA of 390 ca-ses of children before, after and during the treatment and compare the changes during the treatment. Then observe the prognosis. Results There are significant difference of PV levels between cases of different prognosis (P < 0.05). Conclusion The PV levels of children of hand-foot-and-mouth disease will change significantly after effective treat- ment. There are clinical significance in observing and prognosing the hand-foot-and-mouth disease by detecting the se-rum PV levels.

After the problems in military postgraduate information literacy education were analyzed, the construction of a systematic and coherent information literacy education course system for military postgraduates in close combination with their subjects was proposed by setting up multidimensional education target, designing three-stage foundation-subject-innovation course, combining traditional literature retrieval course and embedded professional course, combining case teaching, heuristic discussion and innovative talent information literacy training approach, by infiltrating the physical and virtual space both in and outside university, and by participating in the study and research activities of postgraduates.

Object A novel microwave-heated extraction (MHE) method was studied for the extraction of glycyrrhizic acid from Glycyrrhiza uralensis Fisch. Methods Several factors, such as temperature, time and microwave power were investigated and the appropriate MHE conditions were obtained from the orthogonal test. Under the optimum conditions, the optimal solvent was selected and the MHE was compared with ultrasonic extraction, leaching at room temperature and Soxhlet extraction,. Results The optimum conditions of MHE is extracting for another 40 min in 0.5% ammonia water after heated to 60 ℃ by microwave of 2 000 W. Yield of glycyrrhizic acid was about equal to that of Soxhlet extraction for 4 h, and that of leaching at room temperature for 44.3 h. Conclusion The MHE method is fast, efficient, energy-saving and high-selective, which is recommendable to the application to active compounds extraction from Chinese herbal medicines.

To guarantee the research and establishment of the modern basic theory of traditional Chinese medicine, We firstly proposed the concept of the academic standards of the modern basic theory of traditional Chinese medicine and its logical structure and standards points in this paper. According to the research progress at home and abroad, we explored the basic concept of academic, academic standards, academic of Chinese medicine, academic standards of Chinese medicine in depth, given the logical definition of relevant concepts, and revealed the connotation and logical hierarchy relationship between different concepts. On this basis, we proposed three-level standards points of the academic standards of Chinese medicine. All of these works mentioned above would provide a preliminary standards protection for the academic research of traditional Chinese medicine and the establishment of the modern basic theory of traditional Chinese medicine.

Around the core issue how to evaluate and test hypothesis, starting from the concept of hypothesis and scientific hypothesis, learning form recent progress and understanding at home and abroad, we have analyzed the type of scientific hypothesis, test methods and pre-mortem and post-mortem evaluation criteria in depth, established scientific vision and discipline ruler, explored the awareness level of the Chinese medicine hypothesis, pointed out the problems and gaps. Whereby, we have analyzed and demonstrated brain regulating five internal organs concept of wholism scientific hypothesis, and proven it belongs to the scientific hypothesis. We were confident that these works mentioned above would lead the theoretical reform changing Chinese medicine hypothesis from traditional description to the nature clarification.

SuperparamagneticSiO2@Fe3O4microspherewithcore-shellstructurewaspreparedbythe method of hydro-thermal and St?ber method, and modified by (3-aminopropyl) triethoxysilane ( APTES) . The obtained amino-Fe3 O4@SiO2 microsphere with controlled surface charge properties was characterized by SEM and TEM, and the surface electric property of amino-microsphere was investigated by Zeta potential measurement. The microsphere was used to extract DNA from human blood, and the solid phase extraction method by microspheres was developed. The mechanism of action between Aminated-Fe3 O4@SiO2 microsphere and DNA was explored, and the gel electrophoresis and PCR test were done on the extraction product. The result showed that genomic DNA with high purity was successfully extracted from whole blood by using amino-Fe3 O4@SiO2 microsphere, with the extraction rate about 70%, the saturated adsorption capacity for DNA was about 40 ng/μg, and the elution could be directly used for further bio-analysis.
