RESUMO
BACKGROUND: Patients with gastrointestinal tumors often suffer from poor nutritional status during treatment. Surgery is the main treatment for these patients, but the long postoperative recovery period is often accompanied by digestive and absorption dysfunction, leading to further deterioration of the nutritional status. Early enteral nutrition support is hypothesized to be helpful in improving this situation, but the exact effects have yet to be studied in depth. AIM: To observe the effect of early enteral nutritional support on postoperative recovery in patients with surgically treated gastrointestinal tract tumors, with the expectation that by improving the nutritional status of patients, the recovery process would be accelerated and the incidence of complications would be reduced, thus improving the quality of life. METHODS: A retrospective analysis of 121 patients with gastrointestinal tract tumors treated in our hospital from January 2020 to January 2023 was performed. Fifty-three of these patients received complete parenteral nutrition support as the control group for this study. The other 68 patients received early enteral nutritional support as the observation group of this study. The clinical indicators comparing the two groups included time to fever, time to recovery of postoperative bowel function, time to postoperative exhaustion, and length of hospital stay. The changes in immune function and nutritional indexes in the two groups were compared. Furthermore, we utilized the SF-36 scale to compare the changes in the quality of life between the two groups of patients. Finally, the occurrence of postoperative complications between the two patient groups was also compared. RESULTS: The postoperative fever time, postoperative bowel function recovery time, postoperative exhaustion time, and hospitalization time were all higher in the control group than in the observation group (P < 0.05). The levels of CD3+, CD4+, immunoglobulin (Ig) A, IgM, and IgG in the observation group were significantly higher than those in the control group at 1 d and 7 d postoperatively, while CD8+ was lower than in the control group (P < 0.05). Total protein, albumin, prealbumin, and transferrin levels were significantly higher in the observation group than in the control group at 7 d postoperatively (P < 0.05). The SF-36 scores of patients in the observation group were significantly higher than those in the control group (P < 0.0001). The overall incidence of adverse reactions after the intervention was significantly lower in the control group than in the observation group (P = 0.021). CONCLUSION: We found that patients with gastrointestinal tumors are nutritionally vulnerable, and early enteral nutrition support programs can improve the nutritional status of patients and speed up postoperative recovery. This program can not only improve the immune function of the patient and protect the intestinal function, but it can also help to improve the quality of life of the patient. However, this program will increase the incidence of complications in patients. Caution should be taken when adopting early enteral nutrition support measures for patients with gastric cancer. The patient's condition and physical condition should be comprehensively evaluated and closely monitored to prevent possible complications.
RESUMO
Bigelovin (BigV), as traditional Chinese medicine, has been shown to inhibit the malignant progression of hepatocellular carcinoma (HCC). This study aimed to investigate whether BigV affects the development of HCC by targeting the MAPT and Fas/FasL pathway. Human HCC cell lines HepG2 and SMMC-7721 were used for this study. Cells were treated with BigV, sh-MAPT, and MAPT. The viability, migration, and apoptosis of HCC cells were detected by CCK-8, Transwell, and flow cytometry assays, respectively. Immunofluorescence and immunoprecipitation were used to verify the relationship between MAPT and Fas. Subcutaneous xenograft tumor and tail vein-injected lung metastases mouse models were constructed for histological observation. Hematoxylin-eosin staining was used to assess lung metastases in HCC. Western blotting was used to measure the expression of migration, apoptosis, and epithelial-mesenchymal transition (EMT) marker proteins, as well as Fas/FasL pathway-related proteins. BigV treatment inhibited the proliferation, migration, and EMT of HCC cells, whereas enhanced cell apoptosis. Moreover, BigV downregulated MAPT expression. The negative effects of sh-MAPT on HCC cell proliferation, migration, and EMT were enhanced by BigV treatment. Conversely, BigV addition attenuated the positive effects of MAPT overexpression on the malignant progression of HCC. In vivo experiments showed that BigV and/or sh-MAPT reduced tumor growth and lung metastasis while promoting tumor cell apoptosis. Furthermore, MAPT could act with Fas and inhibit its expression. sh-MAPT upregulated the expression of Fas/FasL pathway-associated proteins, which were enhanced by BigV administration. BigV suppressed the malignant progression of HCC via activating the MAPT-mediated Fas/FasL pathway.
