Postoperative Radiotherapy Combined With Nimotuzumab Followed by Bemcentinib in High-Risk Patients With Head and Neck Squamous Cell Carcinoma

A Multicenter, Randomized, Controlled, Open-Label, Phase III Clinical Trial.To evaluate the efficacy and safety of postoperative radiotherapy combined with Nimotuzumab followed by Bemcentinib in high-risk patients with head and neck squamous cell carcinoma who are ineligible for cisplatin chemotherapy. The primary endpoint is disease-free survival (DFS). A total of 185 patients will be enrolled in both the study group and the control group, respectively, with a total planned enrollment of 370 patients. Enrollment is expected to be completed within 2 years, followed by a 3-year follow-up period after the last patient is enrolled.

Effect of Lidocaine-Dexmedetomidine on Pain, Inflammation, and Oxidative Stress After Bariatric Surgery.

The goal of this randomized clinical trial is to find out whether giving an intravenous lidocaine + dexmedetomidine combination (LIDEX) during laparoscopic bariatric surgery can lower post-operative pain, inflammation, and oxidative stress in adults with obesity. The main questions it aims to answer are: * Pain control: Does LIDEX reduce pain 24 hours after surgery, as measured with the International Pain Outcomes Questionnaire (IPOQ)? * Biomarkers: Does LIDEX lower blood levels of key inflammatory cytokines-interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and interleukin-10 (IL-10)-and oxidative-stress markers-malondialdehyde (MDA), the reduced/oxidized glutathione ratio (GSH/GSSG), superoxide dismutase (SOD), and catalase-compared with the individual drugs or saline placebo? Researchers will compare four groups: lidocaine alone, dexmedetomidine alone, LIDEX, and placebo (saline solution, a look-alike substance that contains no drug) to learn which approach works best. Participants will: * Receive an intravenous infusion of their assigned study drug(s) during surgery. * Provide three small blood samples (before surgery, immediately after, and three hours after). * Complete a short pain questionnaire (IPOQ) 24 hours after surgery.

Observational of Adjuvant Treatment of Breast Cancer With Liposomal Doxorubicin Regimen

The goal of this observational study aims to observe and evaluate the efficacy and safety of a liposomal doxorubicin containing regimen in the postoperative adjuvant treatment of breast cancer patients.
