Assessment of nutritional status of clinical patients by determining normal range of oral mucosal apoptosis and proliferation rate / 华中科技大学学报（医学）（英德文版）

ABSTRACT

The normal range of oral mucosal cell apoptosis and proliferation rate through a larger sample of non-malnourished crowd was investigated, and the nutritional status of clinical patients was assessed. Of 194 clinical patients selected according to "NRS2002" guidance, there were 167 non-malnourished patients and 27 malnourished cases, respectively. Twelve patients with toxic reactions of grade III after postoperative chemotherapy (POC) were chosen. The oral mucosal epithelial apoptosis and proliferation rate were measured by using flow cytometry. The statistical significance was processed by using unpaired t-test. The results showed that there was no significant difference in gender, age and body weight between malnourished and non-malnourished groups. The normal range of oral mucosal epithelial apoptosis and the proliferation rate was (27.50±1.50)% and (15.12±1.68)% in non-malnourished patients, and that was (19.90±4.14)% and (6.66±5.83)% in the malnourished patients, respectively. It is concluded that the normal range of oral mucosa cell apoptosis and proliferation rate is achieved, which can not be influenced by gender, age, weight and other factors, and could be used as a sensitive and accurate index to assess the nutritional status of clinical patients.
