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 summarize and analyze the characteristics of delayed hemolytic transfusion reaction in children,in order to provide a scientific basis for clinical prevention,and ensure the safety of children's blood transfusion.Methods:The basic situation,clinical symptoms and signs,diagnosis time and disappearance time of alloantibody of delayed hemolytic transfusion reaction in children were retrospectively analyzed.The serological test,routine blood test,biochemical detection and urine analysis results were compared pre-and post-transfusion.Results:Among 15 164 children with repeated blood transfusion,23 cases occurred delayed hemolytic transfusion reactions,with an incidence rate of 0.15％,and mainly children with thalassemia and acute leukemia.39.13％of delayed hemolytic reactions occurred in children with more than 20 times of blood transfusions.Anemia was the main clinical symptom in 86.96％of children.4.35％of children had hypotension and dyspnea.Serological test results showed that the positive rate of direct antiglobulin test was 91.30％,and that of erythrocyte homologous antibody test was 100％.Erythrocyte alloantibodies were common in Rh and Kidd blood group systems,accounting for 73.91％and 13.04％,respectively.Laboratory test results showed that hemoglobin,reticulocyte,spherocyte,total bilirubin,indirect bilirubin,lactate dehydrogenase,serum ferritin and urine color were significantly different after transfusion compared with those before transfusion(all P＜0.05).The average diagnosis time of delayed hemolytic transfusion reactions was 18.56 days,and the average disappearance time of erythrocyte alloantibodies was 118.43 days.Conclusion:The incidence of delayed hemolytic transfusion reaction is high in children with repeated blood transfusion,and the disappearance time of erythrocyte homologous antibody is long.Blood matched ABO,Rh and Kidd blood group antigens should be transfused prophylactically.Once diagnosed,erythrocyte alloantibody corresponding to antigen-negative blood should be used throughout the whole process.

Abstract As dietary issues of children and adolescents become increasingly complex, the assessment of food literacy (FL) is increasingly importance. FL involves a comprehensive cognition and practical ability concerning food among children, playing a key role in fostering healthy eating habits and improving health levels. The article explores the definition and connotations of FL, and introduces eight FL assessment tools in terms of theoretical foundations, dimensions, assessment methods, and their reliability and validity. Moreover, it provides a comparative analysis of these tools by examining their dimensional design, evaluation indicators, strengths, and weaknesses, as well as their applicable subjects and scenarios, aiming to offer references for implementing relevant policies and developing more comprehensive and effective FL assessment tools.

Background: To enhance perioperative outcomes, a perioperative registry that integrates high-quality real-world data throughout the perioperative period is essential. Singapore General Hospital established the Perioperative and Anesthesia Subject Area Registry (PASAR) to unify data from the preoperative, intraoperative, and postoperative stages. This study presents the methodology employed to create this database. Methods: Since 2016, data from surgical patients have been collected from the hospital electronic medical record systems, de-identified, and stored securely in compliance with privacy and data protection laws. As a representative sample, data from initiation in 2016 to December 2022 were collected. Results: As of December 2022, PASAR data comprise 26 tables, encompassing 153,312 patient admissions and 168,977 operation sessions. For this period, the median age of the patients was 60.0 years, sex distribution was balanced, and the majority were Chinese. Hypertension and cardiovascular comorbidities were also prevalent. Information including operation type and time, intensive care unit (ICU) length of stay, and 30-day and 1-year mortality rates were collected. Emergency surgeries resulted in longer ICU stays, but shorter operation times than elective surgeries. Conclusions The PASAR provides a comprehensive and automated approach to gathering high-quality perioperative patient data.

To understand the arbovirus carried by the vector Aedes mosquito in the urban areas of Xishuangbanna Dai Autonomous Prefecture(Xishuangbanna Prefecture)during the dengue fever epidemic season in Yunnan province,real-time RT-PCR analysis for DENV serotyping and E gene detection were conducted on the RNA extracted from Aedes mosquitoes(including Ae.albopictus and Ae.aegypti)collected from August to October and DENV NS1 positive serum collected from July to November 2018 in Xishuangbanna Prefecture.A phylogenetic analysis was performed on the sequences obtained from the positive amplification products targeting Flaviviridae sp..C6/36 Ae.albopictus cells were used to isolate viruses from mosquito homogenates.Isolates with cytopathic effects(CPE)were identified by arbovirus and insect-specific virus RT-PCR and sequencing.The sequences were compared to the online GenBank database by BLAST.The DENV serotyping detection results indicated that two groups of Ae.aegypti among 51 groups of Aedes mosquitoes(1 431 mosquitoes in total)and 52 out of 54 serum samples were positive for DENV-1.One mosquito DENV-1 E gene sequence and 27 serum DENV-1 E gene sequences were obtained.The nucleotide sequence identities of E genes derived between mosquito and serum were 97.4%～100.0% and they belonged to genotype I,which had the closest genetic relationship with DENV-1 from Southeast Asian nations.Additionally,Seventeen La Tina virus(LTNV,belonging to Flaviviridae)strains and four Sarawak virus(SWKV,belonging to Alphateraviridae)strains were identified from 18 isolates using regular CPE isolated from suspensions derived from 51 groups containing vector Aedes mosquitoes,of which three strains were simultaneously positive for both LTNV and SWKV detection.The results from this study indicate that vector Aedes mosquitoes in Xishuangbanna Prefecture carry DENV,LTNV,and SWKV and that further researches on arboviruses and insect-specific viruses is urgent necessary.

BACKGROUND: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011. METHODS: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided). RESULTS: The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107). CONCLUSIONS: The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly. TRIAL REGISTRATION NUMBER NCT03620565, https://register.clinicaltrials.gov.

The direct acting substances of Cuscuta chinensis in vivo were preliminarily identified through the correlation analysis of "metabolites-effect identification" model. The ovariectomized female rats were i.g administered with 95% ethanol extract part, 40% ethanol elution part and n-butanol extract part of Cuscuta chinensis. The serum fingerprints of different parts and times of administration were established by UPLC/Q-TOF-MS. At the same time, serum estradiol (E₂), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were detected. Bivariate correlation analysis and grey correlation analysis were used to screen estrogenic components. The results showed that nine direct acting substances in vivo highly related to estrogen effect were found in the drug containing serum, which were hyperoside, astragalin, methyl quercetin glucuronide, quercetin-diglucuronide, quercetin, apigenin, isoquercitrin, kaempferol glucuronide and kaempferol. We can preliminarily screen out the direct acting substance of estrogen effect of Cuscuta chinensis in vivo based on the research idea of serum spectrum effect correlation. It provides a reliable basis for revealing the estrogeneffective substances of Cuscuta chinensis and confirming the quality markers. This experiment was approved by Harbin University of Commerce Ethics Committees (Approval No. HSDU2020-065).

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.
