Glycyrrhiza uralensis Fish Polysacchoride(GPS)was observed to have mitogenic activity on murine spleen cell proliferation in vitro,The results showed that this mitogenic activity of GPS may be directed to B Iymphocytes,i.e.GPS is a new mitogen of murine B lymphocytes.Furthermore,it was found that B lymphocytes stimulated by GPS was M? depedent and T cell-indepedent.On the contrary,antibodies and IL-2 production was inhibited by GPS in vivo.

The main results of the article are as follows:GS(10ug/ml,25ug/ml,50ug/ml)could augment NK activity of murine spleen cells in vitro(p

BACKGROUND:How to reduce the incidence and mortality of cardiovascular diseases is an urgent concern in the field of public health.
OBJECTIVE:To explore the influence of adenovirus-mediated NSF-siRNA release from vesoactive substance on the cardiac function of a rat model of myocardial infarction.
METHODS:A total of 36 adult Sprague-Dawley rats were applied to establish acute myocardial infarction models by ligating the anterior descending branch of the left coronary artery. After the model was determined by electrocardiogram successful y, NSF-siRNA adenovirus (experimental group), negative adenovirus (control group) and normal saline (normal saline group) were injected near the infarct area of the left ventricle of rats respectively. After 2 weeks, the left ventricular ejection fraction (LVEF) was tested with noninvasive ultrasonic cardiogram. Meanwhile, the left ventricular end-diastolic pressure (LVEDP) and maximum pressure rising speed of left ventricular (dp/dt max) were detected by connecting the right external carotid artery place pipe to the BL-420 biological function experiment system, to evaluate the cardiac function. Subsequently, the rat heart was harvested for serial sections to observe the infarcts range.

AIM: To study the allergic disease in recurrent tonsillitis. METHODS: Immunohistochemical technique was used to investigate interleukin-4(IL-4) production in tonsil. RESULTS:The result showed that: a higher incidence of IL-4 producing cells were found in the tonsils of all ages, and a high density of IL-4 was found in the reticular crypt epithelium and extrafollicular, but low density in germinalcenter. IL-4 has been shown play a crucial role in the pathogensis of allergic disease. CONCLUSION:Allergic disease is an important reason of recurrent tonsillitis. The conclusion will give a new way to cure recurrent tonsillitis.

ERS is a kind of universal existence in various cellular stress response.Recently, the research shows that ERS may affect bone metabolism balance from different ways.However, the specific mechanism is still not clear.The relationship between ERS and osteoporosis needs further research.This article will firstly introduce the pathways of ERS, then the relationship between the ERS and osteoporosis will be discussed from pancreatic beta cells, osteoblasts, osteoclasts and mesenchymal stem cells.Lastly, I will give perspectives on the future research on treatment of osteoporosis drug.

Low-level laser effects a special biology stimulation that has been widely used in clinic. In this article, the biological effect of low-level laser irradiation was summarized, and the application in different systems, such as immunity, circulation, metabolism and nerves were reviewed.
