Objective To explore the relationship between postoperative cancer-related fatigue and nutritional risk in patients with colorectal cancer. Method Using convenience sampling method, 159 postoperative colorectal cancer patients were interviewed with cancer-related fatigue scale and PG-SGA 7 days after operation. Results The average score of CRF was (21.28 ± 6.06). The score by PG-SGA was (15.18 ± 5.55). About 94.34%patients were in need of nutritional intervention. The postoperative cancer-related fatigue was positively related to PG-SGA scores(all P<0.05). Conclusions The postoperative colorectal cancer patients are at a high risk of malnutrition, with nutrition risk positively related with somatic cancer-related fatigue. The clinical nursing staff should pay attention to the nutritional status of patients and correct their malnutrition so as to reduce the symptoms of cancer-related fatigue.

Objective To investigate the variability in biochemistry in cerebral palsy children who accepted rehabilitation exercise. Methods From March to November, 2015, 24 children with cerebral palsy were measured the levels of hemoglobin, creatine kinase and blood urea before treatment. They all accepted routine rehabilitation exercise, and were measured hemoglobin, creatine kinase and blood urea again one week after treatment as the load increased, and six weeks after treatment at the end of exercise. They were assessed with Gross Motor Function Measure (GMFM-88) before and six weeks after treatment. Results The scores of GMFM-88 improved after treat-ment (t>7.12, P<0.001). Hemoglobin decreased (P<0.01), while creatine kinase and blood urea increased one week after treatment (P<0.01). Hemoglobin and blood urea came back to the levels before treatment six weeks after treatment (P?0.05), while creatine kinase reduced (P<0.01), but was still more than that before treatment (P<0.01). Conclusion Hemoglobin, creatine kinase and blood urea may respond the train-ing situation of cycle and the stage of exercise, and indicate the effects of load in the cerebral palsy children accepted rehabilitation exercise.

Objective To predict and identify the linear B-cell epitopes in the major group 3 allergen derived from Derma-tophagoides farina(Der f 3). Methods The linear B-cell epitopes of Der f 3 allergen were analyzed based on the physicochemi-cal properties of amino acids including antigenicity,surface accessibility,flexibility,hydrophilicity,beta-turn by online bioinfor-matics softwares. The eight predicted peptides of linear B-cell epitopes were artificially synthesized and incubated with three aller-gic serum pools(4 serum samples in each),which were consisted of total 12 serum samples from the allergic individuals,and the strong positive epitopes were selected. Results Eight B-cell epitopes from Der f 3 were predicted successfully. Five of eight B-cell epitopes were identified with strong IgE-binding abilities followed by specific IgE assay. The amino acid sequences of them were following:33KAKAGDCP40, 86HASGGEKIQVAEIYQHENYDSMTID110, 118LKTPMTLDQTNAKPVPLPPQGSDVKVG144, 156QEGSYSLP163 and 199DVANGGVDSCQGDSGGPVVD218. Conclusions Five linear B-cell epitopes of Der f 3 allergen have been identified successfully. This result might provide a basis of the diagnosis and treatment for asthma.
