Objective To investigate the effect of endometrial ablation combined with mifepristone in the treatment of abnormal uterine bleeding after renal transplantation .Methods Eighty patients with abnormal uterine bleeding after renal transplantation were selected .According to the random number table method , the patients were divided into study group and control group ,with 40 cases in each group .The control group was treated with endometrial radiofrequency ablation .The study group was treated with mifepristone on the basis of the control group .The therapeutic effects of the two groups were compared ,included vaginal bleeding and complications in 3 months,6 months and 1 year.Results The effective rate of the study group was 92.5%,which was significantly higher than 65.0%of the control group(χ2 =7.935,P<0.05).The incidence rate of complications in the study group was 5.0%,which was significantly lower than 30.0%in the control group (χ2 =7.935,P<0.05).Conclusion The effect of endometrial radiofrequency ablation combined with mifepristone in the treatment of abnormal uterine bleeding after renal transplan -tation is significant ,which is worthy of further popularization and application in clinical practice .

ObjectiveTo investigate the dietary preference and nutritional knowledge needs of the elderly people who dined at meal service sites. MethodsUsing the form of stratified and convenience sampling method with self-designed questionnaire was used， in November 2021， to select 700 elderly people who dine at meal service sites in 7 jurisdictions in Shanghai were selected， and a self-designed questionnaire was used to investigate the basic information. Results91.64% of the elderly surveyed would eat at relatively fixed meal service sites， and the total Dietary Diversity Score （DDS9） was 3.56±1.46. 41.45% of the elderly with diseases preferred unhealthy cooking methods. Only 8.03% of the surveyed seniors said they were unwilling to accept targeted and personalized nutrition tips and reminders. Multivariate logistic regression analysis showed that the probability reaching the “understanding” level of “Food Guide Pagoda for Chinese Residents” and “Four Principles Recommended by the Core Dietary Guidelines for the Elderly” was different in the elderly with different education levels. The willingness of the elderly to expect to receive different nutrition tips and reminders was related to whether they cared about the corresponding contents. There was a statistically significant difference （P<0.05） among the elderly who were concerned about different health problems in terms of the willingness to receive different nutritional tips. There were significant differences in the proportion of elderly people with different health status for intervention （χ²=5.402， P<0.05）. ConclusionThe elderly who dine at meal service sites are highly dependent on the sites， have a low level of dietary diversification， and do not have a high degree of understanding of nutrition-related knowledge， and have a high demand for targeted nutritional interventions. Nutritional interventions for the sick elderly should be piloted through multiple channels.
