Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the safety, feasibility and accuracy of esophageal sponge cytology in esophageal carcinoma screening in high-incidence districts.Methods:Opportunistic screening for esophageal carcinoma was conducted on individuals aged 40-75 years with high-risk factors for esophageal carcinoma and visited out-patient clinic in Lianshui People's Hospital from May 2021 to June 2022. A new esophageal cell collector independently developed in China was used for esophageal sponge cytology sampling followed by cytopathological analysis. Atypical squamous cells or more severe lesions were defined as positive esophageal sponge cytology. Then gastroscopy was performed, and all suspicious areas under the endoscopy were biopsied for histopathological examination. Gastroscopy, biopsy histopathology and esophageal sponge cytology were conducted blindly in pairs. Outcome measures included adverse reactions during sampling, subject tolerability (using a visual simulation score), sampling quality, and diagnostic efficacy of esophageal sponge cytology using gastroscopy plus biopsy histopathology as the gold standard.Results:A total of 1 590 patients completed the screening program. During esophageal sponge cytology sampling, no serious adverse events were observed, and the adverse reactions were mainly manifested as vomiting during sampling [0.31% (5/1 590)] and sore throat after sampling [2.45% (39/1 590)], all of which resolved spontaneously without further medical intervention. The majority of subjects [98.62% (1 568/1 590)] reported good tolerance during the procedure. After sampling, 1 526 (95.97%) subjects had completely expanded sponge material, meeting the standard of good sampling quality. The scanning analysis of the digital pathology system showed that the number of sampled cells in 1 590 subjects ranged (2.01-4.00)×10 6, with a median of 3.48×10 6 cells, which could meet the requirements for interpreting cytological results. Using the positive esophageal sponge cytology for the diagnosis of esophageal carcinoma including high-grade intraepithelial neoplasia, esophageal squamous cell carcinoma and adenocarcinoma of esophagogastric junction, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 98.57% (69/70), 91.51% (1 391/1 520), 34.85% (69/198), 99.93% (1 391/1 392), and 91.82% (1 460/1 590), respectively. Conclusion:Esophageal sponge cytology presents promising diagnostic efficacy for esophageal carcinoma screening, offering a simple, safe, convenient, and effective approach in high-incidence esophageal carcinoma regions.

Objective To explore the predictive value of serum homo sapiens microRNA(hsa-miR)-30c-5p expression in patients with type 2 diabetes mellitus(T2DM)for microvascular complications.Methods A total of 205 T2DM patients admitted to Bazhong Central Hospital from May 2021 to September 2022 were selected as the diabetes group,and the diabetes group was further divided into diabetes with combined group(n=124)and non combined group(n=81)according to the microvascular complications of the patients.In addition,205 healthy people who underwent physical examination during the same period were selected as the control group.The expression of hsa-miR-30c-5p in serum was detected by reverse transcription-polymerase chain reaction(RT-PCR)and compared.The factors affecting microvascular complications were analyzed using multivariate logistic regression analysis,and receiver operating characteristic(ROC)curves were plotted to predict the value of serum hsa-miR-30c-5p expression in predicting microvascular complications in T2DM patients.Results The expression of serum hsa-miR-30c-5p in the combined group(0.58±0.06)and the non-combined group(0.72±0.08)were lower than that in the control group(0.89±0.21),and the differences were significant(t=16.038,7.079,all P=0.001).The combined group was lower than the non-combined group,and the difference was significant(t=14.289,P=0.001).The course of diabetes[(OR(95％CI):3.873(2.976～4.770)],uric acid[(OR(95％CI):2.125(1.211～3.040)]and glycosylated hemoglobin[(OR(95％CI):2.680(1.745～3.616)]were independent risk factors for microvascular complications in T2DM patients(all P＜0.05),while the time within the target range of glucose[(OR(95％CI):0.491(0.135～0.846)]and serum hsa-miR-30c-5p[(OR(95％CI):0.532(2.976～4.770)]were protective factors for microvascular complications in T2DM patients(all P＜0.05).The sensitivity,specificity and area under the curve(95％CI)of serum hsa-mir-30c-5p expression in predicting microvascular complications in T2DM patients were 81.45％,85.19％and 0.802(0.741～0.854),respectively.Conclusion The expression of serum hsa-miR-30c-5p in patients with T2DM is abnormally reduced,and serum hsa-miR-30c-5p is a protective factor for microvascular complications in patients with T2DM.It may have a certain predictive value for microvascular complications in patients with T2DM.

Purpose: This study aimed to investigate the changes in microRNA-130a (miR-130a) and its correlation with cardiotoxicity during epirubicin/cyclophosphamide followed by docetaxel plus trastuzumab (EC-D+T) adjuvant chemotherapy in human epidermal growth factor receptor-2-positive (HER2+) breast cancer patients. Methods: A total of 72 HER2+ breast cancer patients who underwent resection and were scheduled to receive EC-D+T adjuvant therapy were consecutively enrolled. The expression of miR-130a and cardiotoxicity (defined as any of the following situations: 1) absolute decline of left ventricular ejection fraction (LVEF) ≥ 10% and LVEF < 53%; 2) heart failure; 3) acute coronary artery syndromes; and 4) fatal arrhythmia) were assessed every 3 months throughout the 15-month EC-D+T treatment. Results: The accumulating cardiotoxicity rate was 12 (16.7%), of which the incidence of heart failure, acute coronary syndrome, life-threatening arrhythmias, ΔLVEF ≥ 10%, and LVEF < 53% was 0 (0.0%), 1 (1.4%), 0 (0.0%), and 12 (16.7%), respectively. Baseline miR-130a expression was negatively correlated with LVEF (%) and positively correlated with cardiac troponin I. The expression of miR-130a gradually increased in both cardiotoxicity and noncardiotoxicity patients during EC-D+T treatment, while the increment of miR-130a was more obvious in cardiotoxicity patients compared with non-cardiotoxicity patients. Further logistic regression and receiver operating characteristic curve analysis indicated that miR-130a was an independent predictive factor for increased cardiotoxicity risk. Conclusion MiR-130a increases constantly and predicts high cardiotoxicity risk during ECD+T adjuvant chemotherapy in HER2+ breast cancer patients.
