Specific interventions: for nutritional support, firstly a nutritional support team (NST), including one attending doctor or with higher titles, two specialty nurses in charge or in higher position, one pharmacist and one nutritionist, was organized. All team members ensured to be in possession of sufficient knowledge of their own specialty and also received additional NST training. During the treatment, the general and clinical data of patients were collected and assessed for their nutritional state, and factors might contribute to malnutrition were corrected. The doctors and pharmacist mainly accounted for assessing patients and making or adjusting treatment plans. The nutritionist guided each patient with their diet after their nutritional state evaluation. The two specialty nurses gave healthcare education to patients in accordance with their disease progression and physical condition, and supervised patients to record their daily food intake and stick to the nutritional plan made by the nutritionist. Patients were evaluated every 4 weeks for their nutritional state and to adjust their treatment plan accordingly, for a total of 12 weeks; for Baduanjin exercise, all enrolled patients were required to watch the video made by the State Sport General Administration of China, Baduanjin: A Health-care Qigong, twice to get familiar with the exercise. The video is about 20–30 min long. After that, patients were taught to do the exercise by a specialist to correct their moves for 2 weeks. Then they were instructed to do the exercise at their own home on non-hemodialysis days. The time and frequency of the exercise were designed according to previous reports (16 (link)), as 3 times a week, 2 h after each meal to do the exercise 2–3 times for 30–60min, for a total of 12 weeks.
