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 evaluate the value of left echography (LVO) in the diagnosis of false ventricular aneurysm complicated with mural thrombus.Methods:The clinical data of 10 patients with suspected pseudoventricular aneurysm examined by thoracic echocardiography (TTE) in Wuhan Asian Heart Hospital from January 2018 to March 2024 were retrospectively analyzed. All patients underwent LVO examination to further diagnose pseudoventricular tumor and whether it was complicated with mural thrombosis. Computed tomography angiography (CTA) or cardiac magnetic resonance (CMR) examination was used as the gold standard to analyze the diagnostic value of LVO in the diagnosis of pseudoventricular tumor.Results:Among the 10 suspected pseudoventricular tumors examined by TTE, LVO detected 6 cases of left ventricular pseudoaneurysm and 1 case of right ventricular pseudoaneurysm; CTA confirmed that 6 cases of left ventricular pseudoaneurysm detected by LVO were correctly diagnosed, 1 case of right ventricular pseudoaneurysm was misdiagnosed, CMR diagnosed right ventricular diverticula, LVO diagnosis accuracy was 6/7, and 4 cases of thrombi were detected. The detection rate was 4/4. The maximum transverse diameter of the tumor body of the communicating mouth/false ventricular aneurysm was 0.46±0.04. 1 patient underwent coronary artery bypass grafting and resection of false ventricular aneurysm. 1 patient underwent coronary artery interventional stent surgery; 4 routine conservative drug treatment, follow-up observation; One case of right ventricular diverticulum did not require special treatment.Conclusions:LVO contrast agent can clearly show the tumor body and location, measure the tumor entrance and size, and show mural thrombus. It is the first choice for the identification of false ventricular tumor. The diverticula was similar to the image of false ventricular aneurysm, and the sensitivity and specificity of right ventricular wall motion were higher in CMR than in LVO.

Objective:To analyze the incidence of liver function injury in patients infected with 2019-nCoV omicron variant and its influencing factors.Methods:The clinical data and laboratory findings of 897 COVID-19 patients infected with omicron variant in Zhejiang province from February 23 to July 14, 2022 were retrospectively analyzed. Patients were divide into liver function injury group ( n=243) and non-liver function injury group ( n=654) based on liver function indicators. The clinical characteristics and laboratory tests were compared between the two groups, and influencing factors of liver function injury were analyzed. SPSS 26.0 statistical software was used for data analysis. Results:The incidence of liver injury in this series was 27.09% (243/897). The median age of patients in liver injury group was older, the body mass index (BMI) was higher( Z=-6.237 and -2.166, both P<0.05), the proportions of patients with hypertension and diabetes, and with severe clinical classification were higher ( χ2=17.087, 27.509 and 12.945, all P<0.01) ; the proportion of vaccinated patients was lower ( χ2=17.766, P<0.01) than those in non-liver injury group. The levels of platelet, hemoglobin, albumin and potassium in liver injury group were lower than those in non-liver injury group ( Z=-4.631, -2.368, -10.593 and -2.141, all P<0.05), while serum ALT, AST, γ-GT, urea nitrogen, glucose and hs-CRP levels were higher than those in the non-liver injury group ( Z=-7.451, -8.663, -4.410, -3.824, -3.278 and -3.884, all P<0.01). Multivariate Logistic regression analysis showed that age ( OR=2.580, 95% CI 1.429-4.657, P=0.002), history of diabetes ( OR=3.650, 95% CI 1.698-7.849, P=0.001), and decreased hemoglobin ( OR=1.993, 95% CI 1.066-3.726, P=0.031) and increased hs-CRP ( OR=1.797, 95% CI 1.283-2.517, P=0.001) were risk factors associated with liver function injury, while vaccination ( OR=0.499, 95% CI 0.312-0.798, P=0.004) was the protective factor for liver function. Conclusion:Liver function injury is frequently observed in COVID-19 patients infected with omicron variant, which is linked to age, underlying disease, and elevated inflammatory markers; while vaccination can lower the risk of liver injury in infected patients.

Objective: A prognostic risk model for lung adenocarcinoma patients was established based on the cancer genome atlas(TCGA) database to explore the prognostic performance of autophagy related gene risk model for lung adenocarcinoma patients and its correlation with immune microenvironment． Methods: Clinical information and transcriptome data of lung adenocarcinoma patients were downloaded and extracted from TCGA database，and 232 autophagy-related genes were screened from the human autophagy database．cox regression analysis was used to screen out four autophagy genes independently associated with prognosis．The prognostic prediction model of lung adenocarcinoma was constructed by risk score ，and the performance of prediction model was evaluated by ROC curve．The relationship between risk scores and tumor immune microenvironment was explored using ESTIMATE ( estimation of stromal and immune cells in malignant tumour tissues using expression data) and CIBERSORT algo- rithms. Results: Thirty differentially expressed autophagy-related genes were identified in lung adenocarcinoma， of which four autophagy genes (BIRC5，ERO1A，ITGB4，NLRC4 ) could predict the prognosis of the patients. Grouped by risk score，the Kaplan-Meier analysis demonstrated that the survival rate of high-risk group was signifi- cantly lower than that of low-risk group(P＜0. 000 1) ．The ROC curve proved the accuracy of the model in predic- ting the prognosis of lung adenocarcinoma ( AUC = 0. 757 ) ．The ESTIMATE and CIBERSORT analyses revealed that the risk scoring model was associated with multiple immune cells and immune infiltrates in the tumor microenvi- ronment． Conclusion Compared with clinical data，the autophagy gene prognostic risk model can better predict the prognosis of patients with lung adenocarcinoma．In the high-risk group，CD4 + memory quiescent cells can im- prove prognosis in lung adenocarcinoma patients.

Objective: To construct nomogram to predict the risk of bone metastasis in patients with non-small cell lung cancer(NSCLC). Methods: The clinical data of NSCLC patients diagnosed in the hospital were retrospectively analyzed, including the occurrence of bone metastasis, age, gender, pathological type, smoking status, PS score, TN stage, metastasis of other sites before bone metastasis, carcinoembryonic antigen(CEA) level, alpha fetoprotein(AFP) level, serum calcium(Ca2+), serum phosphorus(P), alkaline phosphatase(ALP) level, which were determined by univariate and multivariate logistic regression analysis. Receiver operating characteristic curve(ROC) and decision curve analysis were used, DCA was used to verify the accuracy and clinical benefit of the model, and nomogram was used to visualize the model. Results: Area under the ROC curve(AUC) showed that in the modeling group(n=138) and the validation group(n=92), the AUC value predicted by combined indicators(age, gender, pathological type, CEA, ALP)(modeling group=0.792, validation group=0.629) was higher than that predicted by single indicator. Conclusion The prediction model constructed in this study has good effect and can provide reference for clinical screening of high-risk patients with bone metastasis of NSCLC.

Objective To investigate the prevalence of A2058G or A2059G mutation within 23S rRNA in Treponema pallidum (Tp) from primary syphilis patients chancre samples. Methods Simple PCR was used to screen the positive samples containing Tp DNA. Nested PCR was adopted to amplify the region of the Tp 23S rRNA and the purified amplicons were digested by restriction endonuclease MboⅡand Bsa I respectively and sequenced. Results 39 qualified samples were obtained from 43 chancre samples and all of them were found harboring the A2058G mutation, whereas the A2059G was not detected. Conclusion High frequency of the A2058G mutation within 23S rRNA implicated in macrolide resistance emerges in the circulating Tp in Hengyang. Therefore, macro-lide antibiotics such as azithromycin should be cautiously used as an optional therapy for syphilis.
