ABSTRACT
OBJECTIVE@#To study the association of the level of advanced oxidation protein products (AOPPs) in seminal plasma with teratospermia and the outcome parameters of fertilization (IVF).@*METHODS@#We conducted a cross-sectional study among 272 male patients receiving assisted reproduction treatment in the Center for Reproductive Medicine of our hospital between October, 2018 and March, 2019. The levels of seminal AOPPs and reactive oxygen species (ROS), demographic data, sperm parameters and IVF outcome parameters were analyzed for all the patients. According to the percentage of sperms with normal morphology, the patients were divided before IVF into teratozoospermia group and normal sperm morphology group, and those in teratozoospermia group were further divided into 3 subgroups with mild, moderate and severe teratozoospermia. The patients were also divided on the day oocyte retrieval into 2 groups with fertilizing rates lower (group Ⅰ) and higher (group Ⅱ) than the median rate.@*RESULTS@#We found a significant negative correlation of seminal AOPP level before treatment with the percentage of normal sperm morphology (=0.003) and seminal ROS level (=0.013). The seminal levels of AOPPs (= 0.027) and ROS (=0.036) were significantly elevated in patients with teratospermia, and seminal AOPP level was significantly higher in severe teratospermia group than in mild (=0.019) and moderate (=0.015) teratospermia groups. The seminal levels of AOPPs (=0.003) and ROS (=0.017) on the day of oocyte retrieval were negatively correlated with the fertilization rate in IVF cycles, and the levels of AOPPs (=0.049) and ROS (=0.036) were significantly higher in group Ⅰ than in group Ⅱ.@*CONCLUSIONS@#An elevated level of seminal AOPPs may indicate an increased risk of severe teratospermia and a lower fertilization rate in IVF.

Objective To explore the effect of nurse-social worker-college student volunteer team guide on care-giving competence of the primary caregivers for the long-term bedridden elderly. Methods The research was conveniently focused on a total of 60 long-term bedridden elderly and 30 primary caregivers, pension caregiver in welfare home from March to May 2015. The nurse-social worker-college student volunteer team guide for the primary caregivers included distributing health manual, training skill, psychological support, respite care and so on. The intervention lasted for 3 months, twice a month, 150 minutes each time. This was a self comparison study. The care competence for the primary caregivers and self-care ability of daily activities for the long-term bedridden elderly were conducted before and after intervention. Results Before intervention, the total score of care-giving competence was 59.07 ± 13.42. After intervention, the total score was 66.64 ± 14.16. Before intervention, the scores of caring knowledge, operation technique, behavior and attitudes, decision-making and self-efficacy were as follows:18.48±3.46, 17.95±3.98, 12.16±3.08, 7.98±2.56. Whereas, after intervention, the scores were as follows:20.32±3.58, 20.48±2.74, 14.29±3.03, 9.65±2.07. Each dimension score after intervention was significantly higher than that before intervention (t=-2.87--2.02, P<0.01). For bathing, dressing, indoor transferring and eating in self-care ability of daily activities, the numbers of people in 60 long-term bedridden elderly were 8, 13, 21, 18 before intervention and 17, 24, 43, 29 after intervention. The self-care ability of daily activities of the primary caregivers such as bathing, dressing, indoor transferring and eating after intervention were significantly higher than that before intervention (χ2=4.093-4.857, P<0.05). Conclusions Nurse-social worker-college student volunteer team guide can enhance the care-giving competence of the primary caregivers as well as improve the self-care ability of daily activities for the long-term bedridden elderly.
