At present, diabetes mellitus has become an increasingly serious disease which affects public health in the word. Clinical treatment of diabetes is mainly based on oral hypoglycemic drugs, insulin injections and lifestyle interventions (diet and exercise) . The new intervention method targeting intestinal microflora opens up new ideas for diabetes treatment. This article reviews the application of new intestinal microbial therapy (probiotic treatment, oral prebiotics/synbiotics, fecal microbiota transplantation) and treatment by regulating intestinal microflora (bariatric surgery, antibiotic therapy and traditional Chinese medicine) in diabetes. This article also summarized the nursing intervention based on intestinal microbial therapy so as to improve the understanding of the relationship between intestinal microflora and diabetes, and provide a reference for treatment and nursing care for type 2 diabetes.

Objective: To study the effect of different proportions of piper chinaroot and rheum palmatum on the dissolution rate of five effective components (aloe emodin, emodin acid, emodin, emodin, emodin methyl ether). Methods: The high performance liquid chromatography (HPLC) method was used to analyz the contents of five effective components of rheum palmatum in the extracts of different combination of piper chinaroot and rheum palmatum. The tests were carried out by Thermo C18 (250 mm×4.6 mm, 5 μm) by gradient elution with methanol and 0.1% phosphoric acid water solution as mobile phase at a flow rate of 1ml/min, the column temperature was 30 ℃ and the detection wavelength was 254 nm. Results: The linear ranges of aloe emodin, emodin acid, emodin, emodin, emodin methyl ether were 0.018 5-0.741 8, 0.017 9-0.717 8, 0.015 9-0.635 5, 0.054 2-2.167 2, 0.016 2-0.646 4 μg, respectively. The average recoveries of aloe emodin, emodin acid, emodin, emodin, emodin methyl ether were 94.35%, 95.50%, 100.61%, 96.27%, 97.39%, and the RSDs were 1.81%, 1.99%, 2.84%, 2.71%, and 1.86%, respectively. Compared with rheum palmatumby single extract, the content of aloe emodin and emodin were increased by 5 proportions (3:1, 2:1, 1:1, 1:2, 1:3), while the content of emodin and emodin methyl ether were decreased. Conclusions The optimal compatibility proportion of piper chinaroot and rheum palmatum is 1:1.

Based on the concept definition and research status of the core competencies for home-based elderly caregivers,combined with the current development situation of China's elderly care industry and the relevant experience of Japan,Germany,and other countries in the construction of elderly care service systems,this paper sorted out that the core competencies for home-based elderly caregivers in China at this stage,such as elderly care skills,legal and ethical qualities,communication skills,and digital intelligence application capabilities,were relatively weak and cannot meet the comprehensive requirements of the current complex social environment,the individual needs and complex psychology of disabled elderly,and traditional concepts for caregivers.By closely integrating the active aging strategy proposed by the Party and our country,it was clear that home-based elderly caregivers should possess four core competencies,including comprehensive elderly care skills,basic legal and ethical qualities,good communication skills,and necessary informatization application capabilities.It was recommended that training institutions and universities enhance the core competencies for home-based elderly care caregivers by conducting training courses in elderly care,basic legal ethics,communication skills,and the use of smart devices,with a view to providing references for the sustainable development of elderly care.

Objective To explore the relationship of quality of life with optimisms and sense of coherence in adult kidney transplant recipients. Method A total of 295 kidney transplant recipients participated in the study by a self-designed general questionnaire, revised life orientation test (LOT-R), sense of coherence (SOC-13) and the MOS 36-item short form health survey (MOS SF-36). Results The mean score of mental health scale (PCS) was 47.02±7.30, which differed with different age, employment status and transplant vintage (P ＜0.01). The mean score of phyical health scale (MCS) was 46.87 ±11.14, which differed with education, economic burden and transplant vintage (P ＜0.05). PCS and MCS were positively correlated with the total score of sense of coherence (52.05％) and optimism (23.45％) (P＜0.001). Optimism played a partially mediating role in the relationship between sense of coherence and quality of life. Conclusions The quality of life of kidney transplant recipients needs to be improved, which was at a low level.Optimism (medium to high level) and sense of coherence (medium to low level) are influencing factors of the quality of life. Improving accessment of mental state of patients with kidney transplant receients, paying more atentent and support to their mental change can improve their optimism and sense of coheherce and then life quiality.
