RESUMEN
【Objective】 To analyze the results of maternal anti-D measured prenatally and serological tests of the newborn postnatally, so as to provide a basis for perinatal prevention and treatment of hemolytic disease of the newborn(HDN) in Rh negative pregnant women. 【Methods】 Irregular antibodies screening, antibody identification and titer determination were carried out for pregnant women prenatally. Blood group typing and 3 HDN tests were performed for the infant suspected as HDN. One-month follow up, since the delivery of the infant, concerning the changes in antibody titers, hemoglobin and bilirubin of the infant were monitored. 【Results】 The anti-D titer increased to 512 since 28 weeks in the parturient, 1 024 at 30 weeks of gestation, and decreased to 512 at the time of delivery. The masking effect on RhD antigen was observed after the birth of the child, with a sustained decrease in hemoglobin and a sharp increase in total and indirect bilirubin after 24 h of birth, which peaked within 48 h and gradually decreased thereafter.The antibody titers gradually decreased after birth. 【Conclusion】 Close monitoring of the changes of irregular antibody titer in Rh negative parturients is helpful for the prevention and early treatment of HDN, and hemoglobin changes in the newborn should be monitored immediately after birth, as well as symptomatic treatment to reduce the involvement of affected children.
RESUMEN
MTA is rarely applied in the repair of root fractured section. A case of maxillary second premolar which fractured ten years ago had been connected with MTA in this article and the cone beam CT was used to evaluate the treatment effect.

AIM: To study the protective effects of basic fibroblast growth factor (bFGF) on myocardial ischemia in rats and their underlying mechanism. METHODS: A rat myocardial ischemic injury model was established by left coronary artery ligation. The rats were killed at 2 h, 4 h, 8 h after coronary artery occlusion. The samples of blood and myocardium were collected for observing the expression of Bcl-2 and Bax in myocardial cells and the changes of superoxide dismutase (SOD) or myocardial enzymes. RESULTS: The amount of Bcl-2 protein expression of myocardial cells in ischemia + bFGF group was significantly higher than that in ischemia+saline group (P

The semi-automatic liquid nitrogen extracter is lowcost and easy-to-use,which can prevent the volatilization of the liquid nitrogen during the extraction.
RESUMEN
In order to observe the febrffugal response and analysis on its mechanism of needling "Shang gen" point bilateral infraorbital nerves of rabbits were sected in the experiment. Fever models were made by leukocytic pyrogen. The experiment findings were as follows:1. It was found that when febrile response of leukocytic pyrogen in rabbits was significant, the cAMP content in CSF was strikingly increase (25.14?2.11pmol/L). During electric needling "Shang gen" point of febrile rabbits, however, fever response was markedly inhibited (△T was 0.27?0.07 at 60min); The cAMP content rise in CSF was markedly inhibited (11.22?0.13 pmol/ml).2. After sectioning bilateral infraorbital nerves of rabbits, the fever response of febrile rabbits was not depressed (△T was 0.71?0.06 at 60min) during electric needling "Shang gen" point. In the mean time, the cAMP content in CSF was significantly increased (28.53?1.12 pmol/ml).3. The authors inferred that the mechanism of febrffugal response of electric needling "Shang gen" point might be closely associated with producing nerves impulse (from the that point) which inhibited probablely the synthesis of cAMP through some modes.
RESUMEN
When the fever was induced by leukocytic pyrogen(LP)on rabbits, we observed the effects of acupuncture on the main point of "Du Channel". At the same time measured the changes of cAMP and cGMP levels in CSF of the animals.It was found that cAMP levels increased (cAMP levels of normal group 18.60?1.56 pmol/ml and experimental group 25.30?1.14pmol/ml,P
