The spectrums of intracardiac electrograms, QRS complex wave and T wave which were picked up at the position where pacing electrode is to be located in the endocardia were investigated. Simultaneously, a variety of pacemaker sensitivity testing waves and the load capacities of two kinds of pacing electrode were analysised by a spectral analysis method. The results show that the sp(?)ctral distributions of intracardiac electrograms are below 70Hz, the T waves have lower spectral distributions and the QRS complexs have higher ones, indicating that the frequency band of the QRS wave detection circuit should be 8-45 Hz. The advantages and shortcomings of conventional pacemaker sensitivity testing waves and the load capacities of the pacing electrodes are discussed.

0.05).Conclution:The NHD house can modulate a imbalanced status of Th1/Th2 cells,Some common antigens are contained in both the dermatophagoides pteronyssinus and other allergens:pollen,fungus,et al,which are able to combine with the specific antibodies in serum.This study provides a theoretical basis for the allergen-specific immunotherapy for allergic rhinitis.

The Wenchuan earthquake which took place on May 12 impelled people to sense the life for its severity and value and urge them to review the perception and behavior of life.The "in awe of bioethics" by Albert Schweitzer reveals that the basic ethical principle is respecting the life and elaborates the theme of holding,improving and esteeming life.In his theory,he advocates the spirit of sharing common weal and woe in the crisis and criticizes the blind egoism with expanded desires and the limited professional idea that leads to the deviant from the concept of respecting life.All of these show considerable theoretical and practical significance on our understanding of the value the concept "in awe of bioethics" should has in the field of culture,human nature and behavior and lead us to the conscious of respecting life.

Objective To explore the TCM syndrome classification of dysmenorrhea from the point of view of experts' experience.Methods The questionnaire on the TCM syndromes of dysmenorrhea was made based on the literature consultation and questionnaire survey with Delphi method.The data was analyzed with the SPSS software for the mathematical statistics and evaluation of positive degree,concentrative degree,coordination degree,and authority degree.Results The return-ratio of first round questionnaire was 96.67% and that of the second round was 100%.Of the 28 syndromes,the important ones were 12,occupying 42.86% of the investigation indices.The variation coefficient of 7 syndromes was smaller than 0.25.The mean value of expert authority degree was 0.82.Conclusion The commonly seen syndromes are qi stagnation and blood stasis,qi deficiency and blood stasis,liver qi stagnation,blood stasis,qi and blood deficiency,liver and kidney deficiency.

Probe into the standard of top-quality teaching materials is the premise of the construction of top-quality teaching materials.“Medical Ethics” by Professor Sun Moyi provides a model. Top-quality teaching materials not only should embody the advanced theories and ideas of education and have distinct academic style and academically creative awareness, but also should be well designed both in logic and systems.

AIM To observe the therapeutic effect of glucomanan on diabetic mice. METHODS The diabetic mice induced by alloxan model was established. The mices were randomly divided into the control and treated group to test level of blood glucose respectively. RESULTS At doses of 100,200 mg?kg -1 ig 1 and 4 h ahead of time,Glucomanan markedly reduced blood glucose level;At doses of 100, 200 mg?kg -1 ig,it markedly reduced blood glucose level of diabetic mice induced by alloxan;Useing glucomanan 100 mg?kg -1 ig bid?3 d constantly reduced amount of water-drinking. CONCLUSION Glucomanan may have significant effect on diabetic mice induced by alloxan.

AIM: To observe the effects of glucomanan on nitric oxide (NO), endothelin (ET), lipid peroxide and superoxide dismutase (SOD) in experimental atherosclerotic rabbits. METHODS: An atherosclerotic rabbit model was established by feeding high cholesterol diet supplemented by bovine serum albumin injection bolus. The rabbits were randomly divided into the control, model, and glucomanan treatment group. Blood samples were collected 8 weeks after the treatment. RESULTS: After glucomanan administration for 8 wk, the NO and activity of SOD increased in comparison with model group (P
