Objective To evaluate the clinical application of enteral nutrition by nasojejunal tube insertion and by percutaneous endoscopic gastrostomy (PEG) in elderly patients.Methods A total of 65 elderly patients with dysphagia recruited at our department from January 2010 to November 2014 were divided into the nasojejunal tube feeding group (35 cases) and the PEG feeding group (30 cases).Differences between these two groups in nutritional indexes,immunological indexes,complications and mortality were analyzed retrospectively.Results Serum total protein,albumin and prealbumin and upper arm circumferences all increased after treatment with nasojejunal tube feeding or percutaneous endoscopic gastrostomy (P>0.05).There was overall improvement in nutritional status,as assessed by Nutritional Risk Screening 2002 (NRS2002).Specifically,the before/one month-after-treatment ratio of scores was 3.72±0.91/1.90±0.61 (t=7.24,P<0.01) for the nasojejunal tube feeding group and 3.52±1.23/2.02±0.53 (t=4.17,P<0.01) for the PEG feeding group.Compared with NRS2002 scores at one month post-operation,further improvement was achieved at 3 months postoperation both for the nasojejunal tube feeding group (1.89±0.65,t=5.21,P<0.01) and for the PEG feeding group (1.91±0.62,t=4.40,P<0.01).There was no difference in the indexes of nutrition,immune status or mortality between the two groups (P>0.05).Although improvement in CD3+,CD4+,CD8+,CD4+/CD8+,IgA,IgG,and IgM was seen in both groups after operation,the differences did not reach statistical significance (P>0.05).The incidence of aspiration pneumonia was notably lower (P<0.05) while the incidence of diarrhea was much higher (P<0.05) in the nasojejunal tube feeding group than in the PEG feeding group at one month and three months.The two groups had similar causes of death and mortality rates.Conclusion Both nasojejunal tube and PEG feeding can improve the nutritional status of elderly patients with dysphagia.However,the choice for the route of nutrition should be individualized.

BACKGROUND:In recent years, the application of stem cel s to treat autoimmune diseases has become a hot spot. But, studies on umbilical cord blood mesenchymal stem cel s transplantation for the treatment of polymyositis/dermatomyositis are rarely reported. OBJECTIVE:To explore the immunologic mechanism of Th cytokines on the occurrence and development of polymyositis/dermatomyositis by observing the changes in serum interferon-γ, interleukin-4 and interleukin-17 in patients after umbilical cord blood mesenchymal stem cel s transplantation. METHODS:Eighty-one polymyositis/dermatomyositis patients were selected and divided into conventional therapy group (n=44) undergoing glucocorticoid and immunosuppressants therapy and cel transplantation group (n=37) undergoing intravenous infusion of umbilical cord blood mesenchymal stem cel s at a density of (3.5-5.2 )×107 . Dosing regimen was same in the two groups. After fol ow-up of 1, 3, 6 months, the changes of creatine kinase and myodynamia were evaluated;after fol ow-up of 3 and 6 months, lung imaging was evaluated;in the cel transplantation group, interferon-γ, interleukin-4 and interleukin-17 levels were detected before treatment and at 3 and 6 months after treatment. RESULTS AND CONCLUSION:At 1, 3, 6 months after treatment, the creatine kinase level was significantly decreased, and the muscle force grade was significantly increased in both groups (both P<0.001). Compared with the conventional therapy group, the creatine kinase level was lower and the muscle force grade was higher in the cel transplantation group (both P<0.001). Results from lung imaging test showed a remarkable improvement after cel transplantation, and it indicated that umbilical cord blood mesenchymal stem cel s transplantation had good stability. At 6 months after transplantation, the level of interferon-γwas significantly increased, while the interleukin-4 level was decreased significantly (both P<0.01);at 3, 6 months after cel transplantation, the levels of interleukin-17 were significantly decreased (P<0.01). Levels of interleukin-4 and interleukin-17 were positively correlated with the level of creatine kinase at 6 months after cel transplantation (r=0.467, 0.488, both P<0.05), but there was no obvious correlation between the levels of interferon-γand creatine kinase (r=0.213, P>0.05). These findings indicate umbilical cord blood mesenchymal stem cel s transplantation combined with glucocorticoid and immunosuppressants therapy can adjust immune network effects and improve the immune tolerance in polymyositis/dermatomyositis patients, which is safe and effective.
