Objective To compare the long-term prognosis of elderly patients with stageⅠnon-small cell lung cancer (NSCLC) after lobectomy or segmentectomy. Methods Data of elderly patients with stageⅠNSCLC between 2010 and 2020 were collected from the SEER database. According to the resection method, patients were divided into a lobectomy group and a segmentectomy group. The overall survival (OS) and lung cancer-specific survival (LCSS) of the two groups were compared by propensity score matching (lobectomy : segmentectomy=2 : 1). Results A total of 9990 patients were included, including 5840 (58.46%) females and 4150 (41.54%) males, with an average age of (70.48±6.47) years. Among them, 9029 patients were in the lobectomy group and 961 patients were in the segmentectomy group. After propensity score matching, a total of 2883 patients were matched, including 1 922 patients in the lobectomy group and 961 patients in the segmentectomy group. There was no statistical difference in baseline data between the two groups (P>0.05). The 10-year OS rate and LCSS rate of the lobectomy group were higher than those of the segmentectomy group (OS: 51.15% vs. 38.35%, P<0.01; LCSS: 79.68% vs. 71.52%, P<0.01). Subgroup analysis showed that the survival advantage of lobectomy was found in patients aged 60-<70 years and ≥80 years; for patients 70-<80 years, there was no statistical difference in OS or LCSS between the two surgical methods (P>0.05). In addition, for patients with tumor diameter ≤2 cm (stages ⅠA1-ⅠA2), lymph node dissection number≥10, and receiving adjuvant radiotherapy/chemotherapy, segmentectomy could also achieve a similar prognosis as lobectomy. Conclusion Overall, for elderly patients with stage ⅠNSCLC, lobectomy can achieve better OS and LCSS. However, individual differences, tumor characteristics, and perioperative treatment plans should be considered comprehensively to determine the surgical method for elderly patients with stageⅠNSCLC.

Objective To evaluate the current situation of disease control in middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD) and analyze the relationship with disease cognition. Methods Among the 360 middle-aged and elderly COPD patients diagnosed and treated in our hospital from January 2022 to June 2024 were retrospectively selected as research subjects, and the COPD Assessment Test Questionnaire (CAT), COPD Patient Knowledge Questionnaire (BCKQ) and the hampion Health Belief Model Scale were used to evaluate disease control, disease cognition and health beliefs in COPD patients. The Pearson chi-square test was used to analyze the relationship between disease control level and disease cognition and health beliefs in older patients with COPD. Results A total of 360 middle-aged and elderly COPD patients, 112 were in the complete control group, 189 were in the partial control group, and 59 were in the uncontrolled group, the disease control rate was 83.61%. The differences in disease cognitive scores, severity cognition, susceptibility cognition, disorder cognition, benefit cognition, health motivation, self-efficacy score and total health belief scores in middle-aged and elderly COPD patients with different disease control conditions are statistically significant. The scores of the complete control group were higher than those of partial control group and uncontrolled group, and the scores of partial control group were higher than those of the uncontrolled group (P <0.05). The disease control level of middle-aged and elderly patients with COPD is positively correlated with disease cognitive level and health belief in all dimensions. The higher the disease control level, the higher the disease cognitive level and health belief in the patient . Conclusions Middle-aged and elderly COPD patients still have insufficient awareness of the disease, and the level of disease control needs to be improved. There is a significant correlation between disease cognition, health beliefs and the level of disease control, and the improved cognitive level may help to improve the disease management and control effect. For middle-aged and elderly COPD patients, the community can provide health education courses, personalized health guidance and self-management training to enhance their awareness of diseases, so as to improve the long-term management of COPD and the quality of life of patients.

Traumatic brain injury (TBI) is a significant global public health challenge, with an estimated mortality rate of 13 per 100,000 people in China. Bedsides the immediate neurological consequences,[1] TBI is associated with long-term sequelae and an elevated risk of neurodegenerative conditions such as dementia, Parkinson’s disease, and epilepsy. Moreover, TBI can induce systemic effects, including acute gastrointestinal injury (AGI), contributing to poor patient outcomes.[2]

Objective To investigate the effect of bronchoscopic balloon dilation treatment of different intervals on the tracheal intubation-induced subglottic stenosis in children. Methods Children with tracheal intubation-induced subglottic cicatricial stenosis were selected as the research objects. Among the 36 children with pure balloon dilation treatment, 20 cases were enrolled in the observation group and 16 cases were enrolled in the control group. In the observation group, electronic bronchoscopy was performed at 3 days after the first-time balloon dilation treatment, and those with grade 2 or higher stenosis received the second-time balloon dilation treatment. The follow-up treatment principle was as follows. If there was obvious retraction compared with the previous time and the stenosis was grade 2 or higher, the balloon dilation treatment would be performed again after an interval of 3 days; if there was no obvious retraction, the evaluation would be performed again after an interval of 2 weeks until there was no obvious retraction in the stenosis site under endoscopy for 3 times in 6 consecutive weeks, and the degree of stenosis was less than 25%, and then the electronic bronchoscopy evaluation would be stopped. In the control group, electronic bronchoscopy was performed 7 days after the first-time balloon dilation treatment, and those with grade 2 or higher stenosis received the second-time balloon dilation treatment. The follow-up treatment principle was as follows. If there was obvious retraction compared with the previous time and the stenosis was grade 2 or higher, the balloon dilation treatment would be performed again after an interval of 7 days; the evaluation method for those without obvious retraction was the same as the observation group. The follow-up duration ranged from 6 to 9 months. Results There was no significant difference in the total number of treatments and outcomes between the two groups (P>0.05). The treatment duration of the observation group was significantly shorter than that of the control group (P < 0.05). There were no significant differences in intraoperative complications such as bleeding, oxygen saturation decrease, heart rate decrease, and blood pressure decrease during anesthesia between the two groups (P>0.05). There were no significant differences in postoperative fever, aggravated laryngeal stridor, and dyspnea between the two groups (P>0.05). There were no significant differences in dyspnea, activity tolerance, and the need for long-term oxygen therapy between the two groups (P>0.05). Conclusion Most of the tracheal intubation-induced subglottic cicatricial stenosis in children has a good medium- and long-term effect through pure balloon dilation treatment. Shortening the interval of pure balloon dilation to 3 days can shorten the total treatment duration, alleviate the psychological burden of parents, but does not increase their economic burden. There are no significant differences in intraoperative and postoperative complications, outcomes, and long-term follow-up compared with the original interval of 5 to 7 days.

Objective    To compare the clinical efficacy of different surgical approaches for Siewert type Ⅱ adenocarcinoma of esophagogastric junction (AEG). Methods    The clinical data of the patients with Siewert type Ⅱ AEG who received sugeries in the Department of Thoracic Surgery of Gansu Provincial People's Hospital from August 2014 to December 2019 were retrospectively analyzed. The patients were divided into two groups according to the surgical approach: a transabdominal group (transabdominal diaphragmatic esophageal hiatus approach) and a combined group (thoracoabdominal combined with right thoracic approach). Perioperative clinical data and postoperative follow-up data were collected to compare the short- and long-term efficacy of the two groups. Results     A total of 87 patients were enrolled. There were 48 patients (31 males and 17 females, with an average age of 60.85±8.47 years) in the transabdominal group, and 39 patients (25 males and 14 females, with an average age of 61.13±8.51 years) in the combined group. There was no statistical difference between the two groups in the baseline indicators such as gender, age, tumor size and stage (P>0.05). Compared with the combined group, the operation time, intraoperative blood loss, postoperative bed rest time, postoperative total drainage volume were shorter or less, and the visual analogue scale score on the 3rd day after surgery were lower in the transabdominal group (P<0.05). However, the total number of lymph nodes dissected, the number of thoracic lymph nodes dissected and the number of positive thoracic lymph nodes in the combined group were larger than those in the transabdominal group, and the differences were statistically significant (P=0.001). The median survival time in the combined group and transabdominal group was 25.85 months and 20.86 months, respectively. The 3-year overall survival rate of the combined group was higher than that of the transabdominal group (46.2% vs. 38.9%, χ2=5.995, P=0.014). However, there was no statistical difference between the two groups in the postoperative catheter time, esophageal and gastric resection margin distance, number of abdominal lymph nodes dissected, number of positive abdominal lymph nodes, or incidence of postoperative complications (P>0.05). Conclusion    For patients with Siewert type Ⅱ adenocarcinoma of esophagogastric junction, thoracoabdominal combined with right thoracic approach is safe and effective, and has advantages in thoracic lymph node dissection, bringing more benefits to the patients, so it is recommended to be popularized in clinical practice.

Objective To evaluate the short-term outcome of robot-assisted thoracoscopic surgery (RATS) for the treatment of posterior mediastinal neurogenic tumour. Methods The clinical data of consecutive patients with mediastinal neurogenic tumors who received RATS treatment completed by the same operator in the Department of Thoracic Surgery, Gansu Provincial People's Hospital from June 2016 to June 2022 were retrospectively analyzed. The tumors were preoperatively localized and evaluated using magnetic resonance imaging or enhanced CT. Results A total of 35 patients were enrolled, including 19 males and 16 females with a mean age of 34.9±7.1 years. All patients successfully completed the resection of posterior mediastinal neurogenic tumors under RATS, and no conversion to thoracotomy occurred during the operation. The average operative time was 62.3±18.0 min, docking time was 10.3±2.6 min, intraoperative bleeding was 33.9±21.6 mL, postoperative 24-hour chest drainage was 69.0±28.9 mL, postoperative chest drainage time was 2.0 (1.0, 3.0) d and the postoperative hospital stay was 3.0 (2.0, 4.0) d. Postoperative complications occurred in 3 patients, including 2 patients with transient Honor syndrome and 1 patient with transient anhidrosis of the affected upper limb. Conclusion RATS for posterior mediastinal neurogenic tumours is safe, effective and feasible, and allows the full benefit of the robotic surgical system to be exploited.

Objective To confirm the changes of pulmonary artery pressure, neo pulmonary artery stenosis and reoperation in children with unilateral absence of pulmonary artery (UAPA) undergoing pulmonary artery reconstruction. Methods The clinical data of the infants with UAPA undergoing pulmonary artery reconstruction in our hospital from February 19, 2019 to April 15, 2021 were analyzed. Changes in pulmonary artery pressure, neo pulmonary artery stenosis and reoperation were followed up. Results Finally 5 patients were collected, including 4 males and 1 female. The operation age ranged from 13 days to 2.7 years. Cardiac contrast-enhanced CT scans were performed in all children, and 2 patients underwent pulmonary vein wedge angiography to confirm the diagnosis and preoperative evaluation. Preoperative transthoracic echocardiography and intraoperative direct pulmonary arterial pressure measurement indicated that all 5 children had pulmonary hypertension, with a mean pulmonary arterial pressure of 31.3±16.0 mm Hg. Pulmonary arterial pressure decreased immediately after pulmonary artery reconstruction to 16.8±4.2 mm Hg. The mean follow-up time was 18.9±4.7 months. All 5 patients survived during the follow-up period, and 1 patient had neo pulmonary artery stenosis or even occlusion and was re-operated. Conclusion Pulmonary artery reconstruction can effectively alleviate the pulmonary hypertension in children with UAPA. The patency of the neo pulmonary artery should be closely followed up after surgery, and re-pulmonary angioplasty should be performed if necessary.
