Objective:To investigate the feasibility and safety of implementing a domestic vehicle-mounted remote mobile robotic surgical system in thyroid surgery applications, integrated with 5G communication technology.Methods:Using the main system located on the vehicle-mounted mobile robot operating platform of the 960th Hospital of PLA Joint Logistics Support Force and the slave system of Weifang Traditional Chinese Hospital, the remote radical thyroidectomy 5G communication technology, and analyze the clinical and information transmission data of two female patients who underwent remote mobile robot thyroid cancer surgery on October 21, 2024 at Weifang Traditional Chinese Medicine Hospital.Results:The remote radical thyroidectomy was conducted by the robosurgeons utilizing a vehicle-mounted mobile robotic surgical system, and the procedure was successfully completed without necessitating intermediate open surgery. The operation durations for patient 1 and patient 2 were 135 minutes and 108 minutes, respectively, with 7 and 13 lymph nodes dissected, respectively. The average delay in surgical data transmission was recorded at 61.9 milliseconds, with no instances of signal interruption or frame loss. The procedure proceeded smoothly, without any jamming, and the audio and video transmissions were consistently clear. Follow up for 21 days after surgery showed no complications such as hoarseness, skin damage, or lymphatic fistula.Conclusion:The implementation of a vehicle-mounted remote mobile robotic surgery system for thyroid surgery has demonstrated safety and feasibility. Furthermore, the utilization of the 5G network offers rapid data transmission and minimal latency, closely approximating the therapeutic efficacy of traditional robotic thyroidectomy.

Objective To analyze the clinical features of overlap syndromes(OS),I.e.,chronic obstructive pulmonary disease(COPD)complicated with obstructive sleep apnea hypoventilation syndrome (OSAHS).MethodsFrequency of episodes of acute exacerbation,severity,quality of life,exercise endurance,complications and three-year survival rate were investigated in eight patients with OS and 10 patients with pure COPD.Results Both quality of life and exercise endurance in OS group were lower than those in COPD group(P＜0.05).Annual frequency of acute exacerbation episodes and severity were more and three-year survival rate was lower in OS group than those in COPD group(P＜0.05).Complications of hypertension,diabetes,erythrocythemia,respiratory failure and heart failure were all more frequent in OS group than those in COPD group.Among all the above clinical features,increased frequency of acute exacerbation episodes was the most significant.Conclusions OS is clinically more severe than pure COPD,so more attention should be paid to it.Survival for patients with OS can not extended by nocturnal oxygen therapy alone,which may be beneficial when combined with biphasic positive airway pressure(BiPAP)or continuous positive airway pressure(CPAP)ventilation.
