Leptin is type I cytokine detected recently.It takes part in physiological action such as energy balance, fat storage and process of metabolism,reproduction and hemopoiesis in vivo.Leptin may be an important role between adipose tissue and genital system.Lack or excessive of leptin is related to infertility in some diseases involving in nutritional status. Leptin takes part in female infertility pathogenesis in hypothalamus pituitary gland gonad axia and other respects.

Bacterial biofilm is responsible for a wide variety of nosocomial infections.Many chronic infectious diseases are closely correlated with biofilm formation in the clinic.As the biofilm growth,bacterial clusters detachment and dispersal from mature mixed-species biofilms will result in repeated acute infections.Here reviews three distinct biofilm dispersal strategies: swarming dispersal,clumping dispersal and surface dispersal.Many factors,such as heredity and increased fluid shear in the environment,contribute to this complex and dynamic process.Fundamental investigation upon biofilm will benefit clinical therapy of biofilm-associated infections.
3.The Change of Serum hCG Level in Preterm Labor and The Relation between hCG and Placental Pathological Changes
Chinese Journal of Perinatal Medicine 1998;0(01):-
Objective To study the change of maternal serum human chorionic gonadotropin(MShCG) in preterm labor and the relationship between hCG and placental pathological changes. Metheds The preterm labor patients were chosen as the research subjects, the normal late-pregnancy women with the same gestational age were chosen as controls. MShCG level were measured by radioimmunoassy (RIA), placental tissue of preterm labor women was examined histologically. hCG in placental tissue was examined by semiquantiative immunohistochemistry. Results MShCG in preterm labor was significantly higher than that of control P
