ABSTRACT
Objective To establish gastric bypass surgery model with SD rat and analyze the influence factors and preventive measures so as to accumulate experience and skills for further developing gastric bypass surgery model on diabetic rat( GK rat) . Methods Gastric by-pass surgery was operated on 30 SD rats. Summarized modeling experience and analyzed various factors affecting modeling success. Results 17 rats weresuccessfully survived after surgery and 13 failed, with the mortality rate 43. 3%. Three rats died during operation, including two for anesthesia and one for heart failure;one died due to anastomotic bleeding two hours after surgery. Eight died in the third day after surgery, including two for infection, two for intestinal necrosis, four for anastomotic stenosis or obstruction. One died because of anastomotic leakage caused by mistaking and satiety the fifth day after surgery. There were no other complications such as wound dehiscence occurred in this group . Conclusion Establishing models of gastric bypass surgery with SD rats which is regarded as pre-experiment of building models of gas-tric bypass surgery with GK rats is economical and feasible. Anesthesia and perioperative management, surgical techniques and infection pre-vention and control are the main factors affecting modeling. The survival rate of rat model could be increased if related factors well controlled.
ABSTRACT
Objective To explore the applications and effect of experience-based health education in maternal nursing in community.Methods According to the random number table,150 women pregnant for the first time were divided into control group and observation group with 75 in each group. In the control group,the traditional method for health education was used and in the observation group the experience-based teaching based on traditional health education.The two groups were compared in terms of the awareness rate of knowledge about maternal and infant health care and the incidence of postpartum depression.Result The awareness of knowledge about maternal and infant health care in the observation group was significantly higher than that of the control group and the incidence of postpartum depression in the observation group was significantly lower than that of the control group(P<0.01).Conclusion Experience-based health education can improve the level of knowledge about maternal and infant health care and reduce the incidence of maternal postpartum depression.
