Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective: To apply network analysis for exploring the relationship of maltreatment experiences and peer relationships with school bullying among middle school students, so as to provide empirical evidences for the development of targeted intervention programs. Methods: From March to April 2024, a total of 2 119 middle school students aged 12-18 in Shantou City were selected through stratified cluster random sampling. Self administered questionnaire was used to collect data on bullying experiences, maltreatment, and peer relationships. The Glasso network model was employed to estimate network structure. Results: The strongest edge in the network of maltreatment experiences, peer relationships and school bullying was the connecting line connecting peer acceptance and peer terrorized low self esteem (edge weight=0.59) among middle school students. The network faked fraudulent victimization was the most central node in the whole network (strength=7.98). The bridge symptoms of the network were sexual abuse, property bullying of others, relational bullying victimization, and verbal bullying of others, with the strongest bridge node being sexual abuse (bridge strength=1.07). In the accuracy estimation of centrality indices, closeness centrality demonstrated the highest accuracy, followed by strength and betweenness, with coefficient of stability of 0.60, 0.44 and 0.21, respectively. The stability of the network was good. Conclusion Peer acceptance has the strongest correlation with peer fear and inferiority, and is closely related to emotional abuse and emotional neglect.

Objective:To investigate the clinicopathological features of pulmonary epithelioid hemangioendothelioma (PEHE).Methods:Eighteen cases of PEHE were collected from August 2011 to December 2018 at the First Affiliated Hospital of Zhengzhou University. All cases were retrospectively studied by hematoxylin and eosin staining and immunohistochemistry (IHC). The clinicopathological features were reviewed; the status of CAMTA1 and TFE3 gene was analyzed and patients′ outcome was followed up.Results:Of the 18 cases, there were 11 males and 7 females with a male to female ratio of 1.6 to 1.0. The patients′ age ranged from 36 to 68 years (mean 52 years). Twelve cases (12/18) showed a single nodule and six cases (6/18) showed multiple bilateral nodules. Seven cases (7/18) involved other organs besides lung. Seventeen (17/18) patients presented with respiratory symptoms and one patient (1/18) presented with abdominal pain. Grossly, the tumors were greyish-white nodules with indistinct borders. Microscopically the tumor cells were epithelioid and arranged in strands and nests, and cytoplasmic vacuoles were commonly noted. The stroma was myxochondroid or hyaline. By IHC, the tumor cells were positive for CD31(18/18), CD34 (16/18), ERG (18/18) and Fli-1 (18/18); CKpan was focally positive in 5 cases (5/18). TFE3 was positive in 3 cases (3/18), and Ki-67 index ranged from 5% to 30%. FISH analysis showed seventeen cases (17/18) had CAMAT1 rearrangement, one case had TFE3 rearrangement displaying a split signal. Eight patients (8/18) had surgical excision, three patients (3/18) had surgery and chemotherapy, and seven patients (7/18) had chemotherapy only. Four patients (4/18) died of the disease.Conclusions:Patients with PEHE have non-specific symptoms, and correct diagnosis depends on pathologic biopsy and the exclusion of other tumors with epithelioid morphology. Some patients with PEHE have poor prognosis, particularly in those who have multiple nodules, peripheral invasion or metastasis.

Objective: To investigate the clinicopathological features and prognostic indicators of primary pulmonary adenoid cystic carcinoma. Methods: Fifty-nine cases of primary pulmonary adenoid cystic carcinoma were collected from August 2011 to December 2017 at the First Affiliated Hospital of Zhengzhou University. All cases were retrospectively studied by hematoxylin-eosin staining and immunohistochemistry. The clinicopathological features were reviewed and patient survival analysis was performed using Kaplan-Meier method and Cox regression model. Status of epidermal growth factor receptor (EGFR), KRAS, BRAF genes was analyzed in 15 of the 59 study cases. Results: Among 59 cases, there were 25 males and 34 females with male to female ratio of 1.0 to 1.4. The patient age ranged from 29 to 81 years with a mean age of 55 years. The tumor max diameters ranged from 1.0 to 9.6 cm with an average diameter of 2.8 cm. Fifteen (25.4%) patients were smokers while 44 patients (74.6%) were non-smokers. Tumors predominantly occurred in the trachea (28/59,47.5%), the left main bronchus (7/59,11.9%) and the right bronchus (5/59,8.5%). Grossly, the tumors were well circumscribed, greyish-white nodules. Microscopically the tumor cells were small and uniform, and arranged in tubular, cribriform, and solid patterns. Immunohistochemistry showed that the tumor cells were positive for CK7, S-100 protein, Sox-10, CD117 and p63. TTF1 was only positive in 2 cases and Ki-67 index ranged from 3% to 40%. Eighteen cases (30.5%) were gradeⅠ, 26 cases (40.1%) grade Ⅱ, and 15 cases (25.4%) grade Ⅲ. Overall, 39 cases (66.1%), 7 cases (11.9%), 10 cases (16.9%), and 3 cases (5.1%) were at stages Ⅰ, Ⅱ, Ⅲ, and Ⅳ, respectively. Twenty-three patients (39.0%) received surgical therapy, 3 patients (5.1%) surgery combined with radiotherapy, 9 patients (15.2%) surgery combined with chemotherapy, and 24 cases (40.7%) chemotherapy only. No mutation of EGFR, KRAS and BRAF was detected in all 15 tested cases. The overall survival rate at the first, third and fifth years was 94.9%, 86.4% and 84.7%, respectively. Prognostic analysis showed that patient′s age and tumor size were statistically associated with the survival (P<0.05). Conclusions Majority of the patients with primary pulmonary adenoid cystic carcinoma are at an early clinical stage with a favorable prognosis. The size of the tumor and the age of the patients are independent prognostic indicators.

Objective: To investigate the clinical symptoms, imaging features, pathologic manifestations and diagnosis of tracheobronchopathia osteochondroplastica (TO). Methods: The clinical data, imaging and pathologic features and outcome of 18 TO patients diagnosed at the First Affiliated Hospital of Zhengzhou University from August 2011 to August 2018 were collected and analyzed. Results: The 18 TO patients included 10 males and 8 females; patients′ age range was 31 to 64 years (mean 52 years). Six patients (6/18) were smokers. The main presenting clinical symptoms included cough in 15 cases, expectoration in eight cases (8/18), hemoptysis in five cases (5/18), chest tightness in four cases, wheezing in three cases and chest pain in two cases. The time interval between the initial symptoms and diagnosis was 1.5 to 360.0 months, and the average time interval was 45.2 months. Blood calcium and phosphorus were normal in 18 patients (18/18). Chest X-ray showed no direct evidence of TO. Six patients (6/18) showed irregular changes in the trachea or bronchial wall by chest CT scan. Three patients (3/18) had mild ventilatory obstruction. TO was classified as: 10 cases (10/18) were scattered type, seven cases (7/18) were diffuse type and one case (1/18) was confluent type. Epithelial squamous metaplasia, submucosal cartilage, submucosal ossification and hematopoietic bone marrow within the ossified areas were the characteristic histopathologic findings of TO. Conclusions TO is a rare benign disorder that shows atypical presentation. CT scan is insensitive, the histopathology shows submucosal cartilage or ossification. TO should be diagnosed by comprehensive consideration of clinical symptoms, imaging and pathology.

Objective: To compare the mutation status of epidermal growth factor receptor (EGFR) between different lesions and clini-cal characteristics of synchronous multiple ground-glass nodules (SMGGNs). Methods: A retrospective analysis was conducted using clinical data from 35 patients with SMGGNs who were admitted to and received surgery at The Fourth Hospital of Hebei Medical Uni-versity Hospital from January 2017 to December 2018. Next generation sequencing (NGS) was performed for all surgical specimens to detect the mutation status of exons 18, 19, 20, and 21 of the EGFR gene to analyze the relationship between the EGFR mutation sta-tus of the lesions and patient gender, age, lesion location, imaging manifestation of nodules, and adenocarcinoma pathological type . Results: The EGFR mutation rate was 65.7% (23/35 patients). Non-smoking patients and females had higher EGFR mutation rates (P=0.015, P<0.001). The EGFR mutation rate of invasive adenocarcinoma nodules was higher than those of atypical adenomatous hyper-plasia, adenocarcinoma in situ, and minimally invasive adenocarcinoma ( P<0.001). Exon 19 deletion and L858R mutation were the most common mutations of the EGFR gene. There was no significant difference between the pathological subtypes of adenocarcino-ma and the EGFR mutant subtype (P=0.707). Among the 27 patients with multiple nodules with detectable EGFR mutations, the EGFR mutation rate was 85.2% (23/27 patients). Conclusions: The EGFR gene mutation status is different in patients with multiple pulmo-nary ground-glass nodules, suggesting that the occurrence and development of each nodule are independent events. EGFR gene muta-tion is closely related to the development of ground-glass nodules, especially in the invasion of tumors.
