BACKGROUND Gastroparesis is a common digestive disorder characterized by delayed gastric emptying,which can lead to symptoms such as nausea,vomiting,abdominal pain,and poor appetite.Traditional Chinese medicine(TCM)has been used for centuries to treat gastrointestinal disorders,including gastroparesis.TCM theory suggests that spleen and stomach qi deficiency syndrome is one of the main pathogenic factors in gastroparesis.Nursing care plays an important role in the treatment of gastroparesis,and TCM nursing interventions have shown promising results in improving patient outcomes.However,there is limited research on the clinical effectiveness of TCM nursing interventions for gastroparesis with spleen stomach deficiency syndrome.This study aimed to evaluate the clinical effect of TCM nursing intervention in the treatment of gastroparesis with spleen stomach deficiency syndrome and to compare it with routine nursing interventions.AIM To analyze the clinical effect of traditional Chinese medicine nursing intervention in the treatment of gastric paraplegia with spleen stomach deficiency syndrome.METHODS From January 2020 to July 2021,80 patients with gastroparesis of spleen stomach qi deficiency type diagnosed in our hospital were selected for the study.The 80 patients were randomly divided into a control group and an experimental group,with 40 cases in each group.During the treatment period,the control group received routine nursing interventions,while the experimental group received traditional Chinese medicine nursing procedures.Compare the nursing effects of the two groups and observe the changes in traditional Chinese medicine symptom scores,pain levels,and sleep quality before and after treatment.RESULTS After treatment,comparing the treatment effects of the two groups,the total effective rate of the experimental group was significantly higher than that of the control group,with statistical significance(P<0.05).There was no statistically significant difference in the TCM symptom score,visual analogue scale(VAS)score,and Pittsburgh sleep quality index(PSQI)score between the two groups before treatment(P>0.05).However,after treatment,the TCM syndrome scores,VAS scores,and PSQI scores of the experimental group were significantly lower than those of the control group,with a statistically significant difference(P<0.05).CONCLUSION In the clinical nursing intervention of patients with mild gastroparesis due to spleen and stomach qi deficiency,the traditional Chinese medicine nursing plan has good clinical application value and nursing effect,and has a good effect on improving patients’pain and sleep quality. 展开更多

Positive interactions are defined as non-trophic interactions where at least one of the interacting species is benefited in terms of fitness and the other remains unaffected.Nevertheless,the bidirectional feedbacks between species may be positive,neutral or negative.Thus,if facilitated species induce negative effects on their‘nurses’,the assumed definition of positive interactions could be reconsidered.Methods We assessed if ecological interactions between cushions of Azorella madreporica and their facilitated species are positive.Specifically,we tested if cover of facilitated species has any costs for cushion plants from an ecophysiological perspective,and if these costs increase with the amount of cover of facilitated species.In addition,through pathway analysis and correlations,we assessed if cover and richness of facilitated species have a direct and/or indirect effect on the fitness of cushion plants.Important Findings We found that facilitated plant species induced a significant cost for their nurses(cushion plants),and this cost increases with cover of the facilitated species.Additionally,the facilitated species exert a strong direct negative effect on the cushion’s fitness and a moderate indirect negative cost evident through the nutrient status and physiological performance of cushion plants.We thus contribute evidence that positive interactions between high mountain cushion plants of central Chile and their‘facilitated’species may be an artifact more than a fact,especially when bidirectional effects are considered;contrasting with the majority of studies that document only one side of the interaction. 展开更多
