Abstract
Objective To investigate the effect and clinical significance of different thoracic surgical approaches for patients with stage IIB–IVA esophageal squamous cell carcinoma on the survival and prognosis of postoperative radiotherapy patients. Methods One hundred thirty-two patients with stage IIB–IVA esophageal squamous cancer who received radiotherapy after surgery were screened for baseline characteristics and survival analysis. The Kaplan-Meier method was used to draw the survival curve for the follow-up data, and the log-rank test was used to compare the difference in survival rate between the two groups. The Cox regression model was used for multivariate survival analysis. Result For stage IIB–IVA esophageal squamous cell carcinoma, the results of multivariate analysis showed that different surgical methods and clinical staging were independent factors affecting the survival and prognosis of patients after radiotherapy. The 1-, 3-, and 5-year survival rates of patients with advanced esophageal cancer through the left chest approach were 84.2%, 61.4%, and 36.8% respectively. The 1-, 3-, and 5-year survival rates of patients with advanced esophageal cancer through the right chest approach were 73.3%, 40.0%, and 21.3% respectively. There was no significant difference in the 1-year survival rate (P = 0.135) between the two surgical procedures. The 3-year survival rate (P < 0.05) and the 5-year survival rate (P < 0.05) were significantly different. Conclusion For patients with stage IIB–IVA esophageal squamous cell carcinoma undergoing radiotherapy after surgery, the long-term survival prognosis of patients after the left thoracic approach is significantly higher than that of the right thoracic approach.

Humulene Inhibits Acute Gastric Mucosal Injury by Enhancing Mucosal Integrity. Antioxidants (Basel) 2021; 10:antiox10050761. [PMID: 34064830 PMCID: PMC8150829 DOI: 10.3390/antiox10050761] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 04/30/2021] [Accepted: 05/07/2021] [Indexed: 12/17/2022] Open
Abstract
This study was designed to determine whether α-humulene, a major constituent in many plants used in fragrances, has a protective role against gastric injury in vivo and in vitro. A rat model of hydrochloric acid (HCl)/ethanol-induced gastritis and human mast cells (HMC-1) were used to investigate the mucosal protective effect of α-humulene. α-Humulene significantly inhibited gastric lesions in HCl/ethanol-induced acute gastritis and decreased gastric acid secretion pyloric ligation-induced gastric ulcers in vivo. In addition, α-humulene reduced the amount of reactive oxygen species and malondialdehyde through upregulation of prostaglandin E2 (PGE2) and superoxide dismutase (SOD). In HMC-1 cells, α-humulene decreased intracellular calcium and increased intracellular cyclic adenosine monophosphate (cAMP) levels, resulting in low histamine levels. α-Humulene also reduced the expression levels of cytokine genes such as interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF) by downregulating nuclear factor-κB (NF-κB) nuclear translocation. Finally, α-humulene upregulated the expression levels of mucin 5AC (Muc5ac), Muc6, trefoil factor 1 (Tff1), trefoil factor 2 (Tff2), and polymeric immunoglobulin receptor (pigr). α-Humulene may attenuate HCl/ethanol-induced gastritis by inhibiting histamine release and NF-κB activation and stimulating antioxidants and mucosal protective factors, particularly Muc5ac and Muc6. Therefore, these data suggest that α-humulene is a potential drug candidate for the treatment of stress-induced or alcoholic gastritis.
