Background:At present,domestic guidelines and consensus recommend the use of nutritional risk screening 2002(NRS 2002)and patient-generated subjective global assessment(PG-SGA)for nutritional risk screening and assessment of patients with gastrointestinal cancer during the perioperative period.However,PG-SGA has higher professional requirements,complex content and time-consuming.In the current busy situation of medical staff,NRS 2002 is more used for screening alone.Aims:To explore the consistency of NRS 2002 and PG-SGA in the assessment of nutritional status and clinical outcomes in patients with gastrointestinal malignancies,and to explore the accuracy of screening using NRS 2002 alone,so as to provide guidance for the establishment of clinical nutritional screening and assessment standards.Methods:A retrospective analysis was conducted on 157 patients with gastrointestinal malignancies who underwent radical operation in the Department of Gastrointestinal Surgery of Xiangya Hospital,Central South University from January 2020 to October 2022.Nutritional screening and evaluation were performed by NRS 2002 and PG-SGA scales and demographic data and nutrition-related laboratory indicators were collected to observe short-term postoperative clinical outcomes.Results:Patients with nutritional risk or malnutrition had lower body mass index(BMI),lymphocytes and prealbumin(P<0.05).The correlation and consistency of NRS 2002 and PG-SGA scales were good(r=0.728,κ=0.46)and the areas under the curve(AUC)for predicting postoperative complications were 0.691 and 0.702,respectively.In addition,nutritional risk and postoperative complications were significantly increased in patients with malnutrition(P<0.05).Conclusions:Therefore,gastrointestinal surgeons can only use NRS2002 to perform nutritional screening of patients and make corresponding nutritional treatment according to the screening results in the case of busy clinical work.

Objective To investigate the expression of bone marrow γ-H2AX in the patients with multiple myeloma(MM) and its correlation with the prognosis.Methods The patients with newly diagnosed MM in this hospital were selected as the case group,and the patients with non-hemopoietic system tumor without obvious morphological abnormalities by bone marrow smear and biopsy served as the control group.The immunohistochemistry was adopted to detect the expression level of bone marrow γ-H2AX in the cases group and control group,the image-Pro Plus(IPP) semiquantitative analysis was performed.The expression differences were compared between the two groups,moreover the case group was re-divided into the strong expression group and weak expression group according to γ-H2AX expression level.Then the relation ship between γ-H2AX expression level and the prognosis in the patients with MM.Results The bone marrow γ-H2AX expression level in the case group was significantly higher than that in the control group (P<0.05);the level of γ-H2AX expression in the strong expression group was significantly stronger than that in the weak expression group (P<0.05).Conclusion The level of γ-H2AX expression was higher among MM patients,and the over expression of γ-H2AX predicts the shorter survival time.
