Objective To investigate relationship between nutritional status and activities of daily living(ADL) in elderly inpatients in Guangzhou. Methods Total of 275 people older than 60 were included in this study from Guangzhou First People's Hospital from July 2018 to June 2019. Their nutritional markers(including BMI, plasma albumin, hemoglobin, total cholesterol, triglyceride),the activities of daily living(ADL) were evaluated with Barthel index and the nutrition risk screening 2002(NRS2002)used to assess the nutritional risk status were collected to analyze the relationship between nutrition and ADL. Results In these subjects, based on the NRS2002 scores(nutritional risk that the NRS2002 scores were equal or greater than 3, and the non-nutritional risk that the NRS2002 scores were less than 3),58.9%(162/275) patients were having nutritional risk and 41.1%(113/275) were having non-nutritional risk. In elderly inpatients,NSR2002 were negatively associated with ADL(r=-0.393,P＜0.05). ADL was positively associated with BMI, plasma albumin and hemoglobin level(P<0.05). Conclusion In the old, the NRS2002 is an influencing marker of activities of daily living in Guangzhou. Reducing the nutritional risk by lowering the NRS2002 scores can improve ADL in the elderly. The incidence of nutritional risk is highly prevalent in elderly and early nutritional treatment will be needed.

Objective To detect the expression of peripheral blood circulating tumor cells CTC in patients with primary liver cancer and to explore the dynamic changes of CTC and its predictive effect on postoperative recurrence and metastasis of primary cancer. Methods The number of CTC in peripheral blood was measured in 134 patients with primary liver cancer and 72 patients with benign liver disease, the expression of AFP was detected, and the correlation between CTC and AFP was analyzed. Then 86 patients with primary liver cancer were selected from 134 patients with primary liver cancer who underwent radical hepatectomy. The values of CTC and AFP in evaluating recurrence and metastasis of primary liver cancer before and after operation were analyzed by CTC and AFP, in peripheral blood of these 86 patients. Results The positive rates of CTC in peripheral blood of patients with primary liver cancer were higher than that of patients with benign liver disease(P< 0.05). The levels of CTC in patients with primary liver cancer were related to AFP level, lymph node metastasis and the number of tumor nodules, but not to age, sex, tumor diameter, differentiation degree, liver cirrhosis and TNM stage. The survival analysis of CTC and AFP in patients with primary liver cancer showed that the early recurrence and metastasis of primary liver cancer after radical resection were closely related to the positive rate of CTC and AFP, and the positive rate of CTC was more effective than that of AFP positive in the diagnosis of recurrence and metastasis after operation, and the combination of the two had the highest predictive value for recurrence and metastasis. Conclusion CTC may be used as a better index to monitor postoperative recurrence and metastasis of primary liver cancer than traditional tumor markers. The combined detection prediction value of tumor markers is higher.
