RESUMEN
Objective: This study aims to investigate the use of cervical tube-type anastomat in endoscopic surgery for esophageal carcinoma (EC) by exploring its advantages and disadvantages. The findings contribute to the existing knowledge and provide valuable insights for future EC treatment. Methods: A retrospective analysis was conducted on data collected from 82 patients who underwent endoscopic surgery for EC at The Central Hospital of Enshi Tujia and Miao Autonomous Prefecture between May 2019 and October 2022. Among the patients, 42 underwent anastomosis with a cervical tube-type anastomat (Group A), while the remaining 40 cases received layered anastomosis (Group B). Various parameters were recorded, including operation time (OT), neck bleeding volume, time to first postoperative ambulation, postoperative oral food intake, and hospitalization time. Pain assessment was performed using the Visual Analogue Score (VAS) before (T0) and at 12h (T1), 24h (T2), and 48h (T3) after surgery. Postoperative complications, changes in weight, hemoglobin (Hb), albumin (ALB) levels, and the patient's quality of life assessed by the SF-36 scale were also evaluated. Results: Group A demonstrated significantly lower OT, neck bleeding volume, VAS scores at T1 and T2, and incidence of postoperative complications compared to Group B, leading to faster postoperative rehabilitation (P < .05). However, the two groups had no statistically significant differences regarding postoperative weight, Hb and ALB levels, and SF-36 scores (P > .05). Conclusions: The use of cervical tube-type anastomat in endoscopic surgery for EC can accelerate postoperative rehabilitation without adversely affecting the postoperative nutritional status and quality of life.
RESUMEN
Potassium in plants accounts for up to 10% dry weight, and participates in different physiological processes. Under drought stress, plant requires more potassium but potassium availability in soil solutes is lowered by decreased soil water content. Forming symbiosis with arbuscular mycorrhizal (AM) fungi not only enlarges exploration range of plant for mineral nutrients and water in soil, but also improves plant drought tolerance. However, the regulation of AM fungi on plant root potassium uptake and translocation from root to shoot was less reported. In current study, the effect of an AM fungus (Rhizophagus irregularis), potassium application (0, 2, and 8 mM), and drought stress (30% field capacity) on Lycium barbarum growth and potassium status was analyzed. Ten weeks after inoculation, R. irregularis colonized more than 58% roots of L. barbarum seedlings, and increased plant growth as well as potassium content. Potassium application increased colonization rate of R. irregularis, plant growth, potassium content, and decreased root/shoot ratio. Drought stress increased colonization rate of R. irregularis and potassium content. Expression of two putative potassium channel genes in root, LbKT1 and LbSKOR, was positively correlated with potassium content in root and leaves, as well as the colonization rate of R. irregularis. The increased L. barbarum growth, potassium content and genes expression, especially under drought stress, suggested that R. irregularis could improve potassium uptake of L. barbarum root and translocation from root to shoot. Whether AM fungi could form a specific mycorrhizal pathway for plant potassium uptake deserves further studies.
