Objective To explore the clinical efficacy and safety of endoscopic endonasal dorsum sellae and posterior clinoid process resection combined with pituitary hemi-transposition in the treatment of pan-sellar area lesions. Methods Clinical data from 57 patients with pan sellar diseases who underwent endoscopic transnasal resection of the posterior clinoid process combined with lateral pituitary displacement surgery in the neurosurgery department of Zhongshan Hospital, Fudan University from January 2019 to January 2025 were collected, and their clinical surgical characteristics and prognosis were analyed. Results A total of 57 patients with pan-sellar area lesions were included in this study, comprising 27 craniopharyngiomas, 7 giant suprasellar pituitary adenomas, 7 chordomas, 6 chondrosarcomas, 5 diaphragma sellae/dorsum sellae meningiomas, and 5 rare lesions. All procedures were completed successfully, and gross total or near-total resection was achieved in all patients. No new neurovascular complications occurred intraoperatively. The follow-up duration ranged from 3 to 24 months. New postoperative anterior pituitary insufficiency occurred in 3 patients (5.3%), and new posterior pituitary insufficiency requiring long-term hormone replacement therapy occurred in 4 patients (7.0%). No additional pituitary dysfunction was observed in the remaining patients. Cerebrospinal fluid rhinorrhea occurred in 1 patient (1.8%) and was successfully repaired. Intracranial infection occurred in 3 patients (5.3%) and resolved after medical treatment. Conclusion Endoscopic resection of the posterior clinoid process combined with lateral displacement of the pituitary gland can effectively expand the surgical space, while repositioning the pituitary gland can reduce the extent of skull base defects. In addition, the risk of pituitary dysfunction caused by lateral displacement of the pituitary gland is relatively low.

BACKGROUND: Prolonged occupational noise exposure poses potential health risks, but its impact on mitochondrial DNA (mtDNA) damage and methylation patterns remains unclear. METHOD: We recruited 306 factory workers, using average binaural high-frequency hearing thresholds from pure-tone audiometry to assess noise exposure. MtDNA damage was evaluated through mitochondrial DNA copy number (mtDNAcn) and lesion rate, and mtDNA methylation changes were identified via pyrophosphate sequencing. RESULTS: There was a reduction in MT-RNR1 methylation of 4.52% (95% CI: -7.43% to -1.62%) among workers with abnormal hearing, whereas changes in the D-loop region were not statistically significant (β = -2.06%, 95% CI: -4.44% to 0.31%). MtDNAcn showed a negative association with MT-RNR1 methylation (β = -0.95, 95% CI: -1.23 to -0.66), while no significant link was found with D-loop methylation (β = -0.05, 95% CI: -0.58 to 0.48). Mediation analysis indicated a significant increase in mtDNAcn by 10.75 units (95% CI: 3.00 to 21.26) in those with abnormal hearing, with MT-RNR1 methylation mediating 35.9% of this effect. CONCLUSIONS These findings suggest that occupational noise exposure may influence compensatory increases in mtDNA content through altered MT-RNR1 methylation.

BACKGROUND: Congenital heart disease (CHD) is a leading cause of birth defect-related mortality. However, more recent CHD mortality data for China are lacking. Additionally, limited studies have evaluated sex, rural-urban, and region-specific disparities of CHD mortality in China. METHODS: We designed a population-based study using data from the Dataset of National Mortality Surveillance in China between 2008 and 2021. We calculated age-adjusted CHD mortality using the sixth census data of China in 2010 as the standard population. We assessed the temporal trends in CHD mortality by age, sex, area, and region from 2008 to 2021 using the joinpoint regression model. RESULTS: From 2008 to 2021, 33,534 deaths were attributed to CHD. The period witnessed a two-fold decrease in the age-adjusted CHD mortality from 1.61 to 0.76 per 100,000 persons (average annual percent change [AAPC] = -5.90%). Females tended to have lower age-adjusted CHD mortality than males, but with a similar decline rate from 2008 to 2021 (females: AAPC = -6.15%; males: AAPC = -5.84%). Similar AAPC values were observed among people living in urban (AAPC = -6.64%) and rural (AAPC = -6.12%) areas. Eastern regions experienced a more pronounced decrease in the age-adjusted CHD mortality (AAPC = -7.86%) than central (AAPC = -5.83%) and western regions (AAPC = -3.71%) between 2008 and 2021. Approximately half of the deaths (46.19%) due to CHD occurred during infancy. The CHD mortality rates in 2021 were lower than those in 2008 for people aged 0-39 years, with the largest decrease observed among children aged 1-4 years (AAPC = -8.26%), followed by infants (AAPC = -7.01%). CONCLUSIONS CHD mortality in China has dramatically decreased from 2008 to 2021. The slower decrease in CHD mortality in the central and western regions than in the eastern regions suggested that public health policymakers should pay more attention to health resources and health education for central and western regions.

Objective:To evaluate long-term outcomes of endoscopic papillectomy (EP) for duodenal papillary adenomas and to identify risk factors for incomplete resection.Methods:Clinical data of 180 patients diagnosed as having duodenal papillary adenoma via postoperative pathology after EP in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2010 to December 2022 were retrospectively analyzed. Patients were divided into two groups based on their postoperative margin status: the complete resection group (negative resection margins) and the incomplete resection group (positive/uncertain resection margins). Recurrence rates were compared between the two groups, and logistic regression analysis was performed to identify risk factors for incomplete resection.Results:Among the 180 patients included in the study, 137 underwent complete resection, and 43 had incomplete resections. Recurrence rate was significantly higher in the incomplete resection group than that in the complete resection group (30.2% VS 15.3%, χ2=4.75, P=0.029). logistic regression analysis indicated that high-grade intraepithelial neoplasia was an independent risk factor for incomplete resection ( OR=2.43, 95% CI:1.12-5.26, P=0.024). Conclusion:Patients with incomplete resection after EP have a higher recurrence rate in the long-term follow-up. High-grade intraepithelial neoplasia is an independent risk factor for incomplete resection. Close surveillance and aggressive management are warranted for patients with positive or uncertain resection margins to mitigate the recurrence risk.

Background: Adrenal venous sampling (AVS) is essential for diagnosing unilateral aldosterone oversecretion in primary aldosteronism (PA). Traditionally, AVS relies on radioimmunoassay (RIA) to measure plasma aldosterone concentration (PAC), although RIA has limited specificity and considerable variability. This study evaluated the role of liquid chromatography-tandem mass spectrometry (LC-MS/MS) in AVS and its impact on clinical outcomes. Methods: Among 230 patients with PA (May 2020 to April 2023) who underwent AVS, successful sampling was achieved in 182 patients (79.1%) under unstimulated conditions and 206 patients (89.6%) under stimulated conditions. PAC levels from peripheral and adrenal veins measured by LC-MS/MS were compared with RIA results. Patient outcomes were categorized according to the Primary Aldosteronism Surgical Outcomes criteria. Results: LC-MS/MS showed significant correlations with PAC levels measured by RIA in AVS (r=0.40 [unstimulated] and r=0.56 [stimulated]; both P<0.001). However, lateralization concordance between RIA and LC-MS/MS was moderate, at only 57.7% (unstimulated) and 64.6% (stimulated). LC-MS/MS identified more unilateral disease than RIA under both unstimulated (61.5% vs. 37.4%, P<0.001) and stimulated conditions (36.4% vs. 9.7%, P<0.001). Patients achieving complete clinical success after adrenalectomy were more accurately identified by LC-MS/MS than RIA under stimulated (55.6% vs. 22.2%, P=0.035), but not in unstimulated conditions. Conclusion LC-MS/MS outperformed RIA in identifying unilateral disease, resulting in higher rates of complete clinical success in adrenalectomy patients when surgical decisions were based on LC-MS/MS lateralization results.

Background: Chemoradiotherapy is the standard treatment for esophageal cancer, but the optimal radiation dose remains undetermined. A dose of 50.4 Gy is commonly used in both neoadjuvant and definitive settings. This study evaluates the outcomes of using 50.4 Gy in neoadjuvant chemoradiotherapy (nCRT). Methods: Patients with esophageal cancer who underwent nCRT with 50.4 Gy radiation followed by surgery between 2010 and 2023 were retrospectively analyzed. They were categorized as achieving pathological complete response (pCR patients) or not (non-pCR patients). Oncological outcomes, including overall survival (OS) and recurrence-free survival (RFS), were assessed. Results: Among 258 patients treated with nCRT, 96.5% completed the treatment protocol, and 74.4% (n=192) proceeded to surgery. These 192 patients formed the analysis cohort. The overall complication rate was 70.3%, with 19.3% classified as major complications. The 30-day and 90-day postoperative mortality rates were both 0.5%. The pCR rate was 45%. Patients with pCR had a 3-year OS rate of 72.7% and a median survival of 125 months, whereas non-pCR patients had a 3-year OS rate of 49.6% and a median survival of 35 months (p=0.002). Additionally, pCR patients had a 3-year RFS rate of 62.0% and a median RFS of 68 months, compared to 33.6% and 20 months, respectively, for non-pCR patients (p<0.001). Conclusion This study reports the outcomes of using 50.4 Gy in nCRT for locally advanced esophageal cancer. The findings affirm the efficacy of 50.4 Gy neoadjuvant chemoradiotherapy in achieving favorable long-term outcomes, particularly among patients with complete pathological response.

Non-neonatal tetanus is an acute, specific, toxic disease in patients over 28 days of age, characterized by continuous rigidity and paroxysmal spasms of the skeletal muscles throughout the body caused by the intrusion of Clostridium tetani through skin or mucosal membrane into the body and reproducing in anaerobic environments to produce exotoxins. The mortality rate of severe patients is close to 100% without medical intervention. Even with aggressive comprehensive treatment, the global mortality rate remains at 30%-50%, making it a potentially fatal disease. In order to standardize the diagnosis, treatment and prevention of non-neonatal tetanus, based on "Regulation for Diagnosis and Treatment of Non-neonatal Tetanus (2019 Edition)", experts have revised this regulation according to clinical practice and recent research progress in this field to guide medical institutions in the prevention and control of non-neonatal tetanus. This article interprets the key points and basis for updating the 2024 edition regulation to guide clinical implementation and application.
