Objective To investigate the perioperative safety of patients with myasthenia gravis who take high doses of oral glucocorticoids. Methods A retrospective analysis was conducted on the clinical data of patients with myasthenia gravis who received oral glucocorticoids and underwent thoracoscopic thymectomy at the Department of Thoracic Surgery, the University of Hong Kong-Shenzhen Hospital from April 2013 to October 2019. Patients were divided into a high-dose steroid group and a medium-to-low dose steroid group based on the dosage of oral steroids, and the clinical data of the two groups were compared. Results A total of 102 patients were included, including 19 (18.62%) males and 83 (81.37%) females, with an average age of (32.25±9.83) years. There were 75 patients in the medium-to-low dose steroid group and 27 patients in the high-dose steroid group. All patients in both groups successfully completed the surgery without major intraoperative bleeding, conversion to open chest surgery, delayed extubation, severe infection, or perioperative death. The daily oral steroid dose for the high-dose steroid group was (35.81±4.29) mg, and for the medium-to-low dose steroid group it was (15.29±2.17) mg. There was no statistical difference in the operation time [(124.69±23.51) min vs. (117.89±21.46) min, P=0.172] and intraoperative blood loss [(21.19±3.48) mL vs. (20.56±3.41) mL, P=0.419] between the two groups. Postoperatively, 12 (11.76%) patients developed complications: one patient of myasthenic crisis (the medium-to-low dose steroid group), which was improved after short-term respiratory support and intravenous immunoglobulin treatment; 11 patients of respiratory/swallowing difficulties (9 in the medium-to-low dose steroid group and 2 in the high-dose steroid group), which were improved after anticholinergic treatment to reduce oral secretions and sputum suction, and the patients were discharged smoothly. There was no statistical difference in the incidence of postoperative complications between the two groups (P=0.637). Conclusion On the basis of good perioperative management, it is safe and feasible for patients with myasthenia gravis who take high dose of oral steroids to undergo thymectomy, and they have the same perioperative safety as patients with medium-to-low dose steroids.

Objective:To explore the relationship between coronary artery measurements combined with C-reactive protein(CRP), erythrocyte sedimentation rate(ESR) and coronary artery lesionsin(CAL) with incomplete Kawasaki disease (IKD) in children.Methods:Sixty-eight cases of pediatric IKD admitted to Huaibei Maternal and Child Health Care Hospital from January 2020 to April 2024 were selected as the IKD group, and 34 healthy children undergoing physical examination during the same period were selected as the control group according to the principle of 2∶1 pairing. Echocardiographic Z values including left coronary artery (LCA)-Z, right coronary artery (RCA)-Z, left anterior descending branch (LAD)-Z, left circumflex branch (LCX)-Z and CRP, ESR were compared between the two groups. General information of children with or without CAL were compared. The multivariate Logistic regression was used to screen the risk factors of IKD combined with CAL, and receiver operating characteristic (ROC) curve was used to analyze the predictive value of each index to IKD combined with CAL.Results:The LCA-Z, RCA-Z, LAD-Z, LCX-Z and the levels of CRP, ESR in the IKD group were higher than those in the control group: 3.26 ± 0.97 vs. 1.35 ± 0.28, 3.46 ± 0.92 vs. 1.01 ± 0.29, 3.18 ± 0.69 vs. 1.18 ± 0.34, 2.97 ± 0.68 vs.1.27 ± 0.34, (39.97 ± 9.03) mg/L vs. (4.21 ± 1.05) mg/L, (59.67 ± 16.34) mm/1 h vs. (12.85 ± 2.43) mm/1 h, there were statistical differences ( P<0.05). The duration of fever, intravenous immunoglobulin (IVIG) treatment response, IVIG start time, creatine kinase (CK), creatine kinase-MB(CK-MB), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) between the children with IKD and CAL, IKD without CAL: (10.02 ± 2.45) d vs. (7.68 ± 1.43) d, 65.22%(15/23) vs. 88.89%(40/45), 60.87%(14/23) vs. 86.67%(39/45), (236.78 ± 59.74) U/L vs. (192.67 ± 35.41) U/L, (45.19 ± 9.85) U/L vs. (33.18 ± 9.87) U/L, (1.78 ± 0.32) μg/L vs. (0.92 ± 0.20) μg/L, there were statistical differences ( P<0.05). Logistic regression analysis showed that the duration of fever, IVIG treatment response, IVIG initiation time, CK, CK-MB, NT-proBNP, echocardiographic Z value, CRP and ESR levels were independent risk factors for IKD combined with CAL ( P<0.05). ROC curve analysis results showed that the area under the curve of IKD combined with CAL predicted by LCA-Z, RCA-Z, LADE-Z, LCX-Z, CRP and ESR was the largest, which was 0.917 (95% CI 0.824 - 0.970), which was higher than that diagnosed by each index alone ( P<0.05). Conclusions:There is a certain relationship between the echocardiographic Z values, CRP and ESR in children with IKD and CAL, which can be used to assist in the evaluation of IKD complicated with CAL.

Objective:To compare the clinical efficacy and adverse events of different postoperative radiotherapy strategies (adjuvant radiotherapy versus salvage radiotherapy) and different irradiation fields (prostate bed versus prostate bed + pelvic radiation) in patients after radical prostatectomy for prostate cancer.Methods:This retrospective analysis included clinical data from 115 patients with localized or locally advanced prostate cancer who received intensity-modulated radiotherapy (IMRT) after radical prostatectomy at Beijing Hospital between March 2014 and September 2023. Among them, 40 patients received adjuvant radiotherapy, and 75 received salvage radiotherapy. And 74 patients received irradiation to both the prostate bed and pelvic (prostate bed + pelvic radiation group), while 41 patients received irradiation to the prostate bed alone (prostate bed irradiation group). Comparison was made between the adjuvant radiotherapy group and salvage radiotherapy group, as well as between prostate bed + pelvic radiation group and prostate bed irradiation group, in terms of overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRRFS), and the incidence of adverse events. Clinical characteristics were compared using the chi-square test. Survival rates were calculated using the Kaplan-Meier method and compared using the log-rank test. Prognostic factors affecting survival were analyzed using Cox multivariate regression.Results:The median follow-up duration was 73.1 months. The 5-year OS, PFS and LRRFS rates for the entire cohort were 96.4%, 86.4%, and 93.2%, respectively. A total of 59 patients (51.3%) experienced grade 1-2 acute radiotherapy-related adverse events, while 43 patients (37.4%) experienced grade 1-2 late radiotherapy-related adverse events. No grade ≥ 3 late adverse events were observed. There were no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups ( P = 0.807, 0.996, and 0.976, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). The OS rate in the prostate bed + pelvic radiation group was significantly lower than that in the prostate bed irradiation group ( P = 0.036), while no significant differences were found in PFS or LRRFS ( P = 0.109 and 0.190, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). Multivariable analysis showed no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups, or between the prostate bed and prostate bed + pelvic irradiation groups ( P = 0.756, 0.341, 0.605; 0.938, 0.987, 0.605, respectively). Conclusions:In the era of modern IMRT, both adjuvant and salvage radiotherapy, as well as prostate bed and prostate bed + pelvic irradiation, demonstrate similar efficacy and safety profiles after radical prostatectomy for prostate cancer. Treatment outcomes were favorable, and adverse events were minimal.

Objective:To investigate the clinical characteristics and prognosis of follicular lymphoma (FL) patients with different primary sites using the Surveillance, Epidemiology, and End Results (SEER) database.Methods:Clinical data of 7167 patients with early-stage FL (stage I-II) from the SEER database between 2000 and 2015 were respectively analyzed. Primary sites were divided into intranodal and extranodal types. Intranodal primary sites included supradiaphragmatic lymph nodes (LN), subphrenic lymph nodes and Waldeyer's ring. Extranodal primary sites consisted of skin, gastrointestinal tract, duodenum, head and neck, other sites. Prognostic factors and overall survival (OS) in patients with different primary sites were analyzed. OS rate was evaluated using Kaplan-Meier method and survival difference between primary sites was compared with log-rank test. Inverse probability treatment weighting (IPTW) and multi-variable analysis were applied to adjust for confounding factors. Multivariate Cox regression analysis of influencing factors of OS was performed.Results:The median age was 63 years old, with the median follow-up time of 63 months. There was no difference in prognosis among the intranodal groups or between the intranodal and extranodal groups. The 10-year OS rates of the supradiaphragmatic lymph LN ( n=2146), subdiaphragmatic LN ( n=2811), and the Waldeyer's ring ( n=151) groups were 70.7%, 69.9% and 73.4%, respectively ( P=0.422 for infradiaphragmatic LN vs. supradiaphragmatic LN, P=1.000 for Waldeyer's ring vs. supradiaphragmatic LN), and 70.3% and 68.9% for intranodal ( n=5108) and extranodal ( n=2059), respectively. There was no significant difference in OS between the groups ( P=0.581) after IPTW adjustment. The most common primary sites in extranodal disease were skin, gastrointestinal tract, head and neck, and duodenum. The 10-year OS for skin, gastrointestinal tract, and cutaneous was 74.2%, 74.7%, and 87.3%, respectively, significantly higher than 55.6% for other sites (duodenum vs. others sites, gastrointestinal vs. others sites, skin vs. others sites: all P<0.001). Multivariate Cox regression analysis revealed that difference in OS was not significant among the intranodal groups or between the intranodal and extranodal groups. However, different extranodal primary site was an independent prognostic factor for OS. Conclusions:Early FL patients with supradiaphragmatic LN, subdiaphragmatic LN and Waldeyer's ring, and between the intranodal and extranodal primary sites obtain similar prognosis. However, early-stage FL patients with different extranodal primary sites have prognostic differences. The prognosis of primary skin, gastrointestinal tract and duodenum is significantly better than that of other extranodal primary sites.

Objective    To compare and analyze the therapeutic effects of robot-assisted lobectomy and segmentectomy for stage ⅠA non-small cell lung cancer with a diameter≤2 cm. Methods    A total of 181 patients with pathologically confirmed stage ⅠA non-small cell lung cancer (diameter≤2 cm) who underwent robot-assisted lobectomy and segmentectomy in our hospital from 2018 to 2021 were included. There were 74 males and 107 females with an average age of 57.50±10.60 years. They were divided into two groups according to the surgical procedure: a segmentectomy group (85 patients) and a lobectomy group (96 patients). Results    There was no statistically significant  difference between the two groups in terms of clinical data such as age, gender, smoking history, basic disease, pathological type, tumour diameter, operative time, postoperative 24 h drainage volume and overall complications (P>0.05). The intraoperative blood loss (33.88±16.26 mL vs. 39.27±19.48 mL, P=0.046), groups of dissected lymph nodes (4.76±1.19 vs. 5.52±1.46, P=0.000), number of dissected lymph nodes (14.81±7.23 vs. 18.06±7.70, P=0.004) and postoperative 72 h drainage volume (561.65±225.31 mL vs. 649.84±324.34 mL, P=0.037) of patients in the segmentectomy were less than those in the lobectomy group. The chest drainage time (5.49±3.92 d vs. 7.60±4.96 d, P=0.002) and postoperative hospital stay time (7.47±4.16 d vs. 9.67±5.50 d, P=0.003) were shorter than those in the lobectomy group. There was no conversion to thoracotomy or perioperative death in the two groups. The postoperative follow-up rate was 100.0% with a longest follow-up time of 48 months. The 3-year recurrence-free survival rates of the segmentectomy group and lobectomy group were 87.7% and 92.4%, respectively (P=0.465). Conclusion    The da Vinci robot-assisted lobectomy and segmentectomy are safe and feasible surgical procedures for patients with stage ⅠA non-small cell lung cancer (diameter≤2 cm), with a similar 3-year recurrence-free survival rate. The lobectomy group has more lymph nodes dissected, while the segmentectomy group is superior to the lobectomy group in terms of intraoperative blood loss, postoperative 72 h chest drainage volume, chest drainage time and postoperative hospitalization time.
