Objective To investigate the effects of soluble receptor for advanced glycation end products(sRAGE)on the changes and functions of myocardial tissue proteins in mice during myocardial ischemia/reperfusion(I/R).Methods Establish the myocardial I/R model using cardiac-specific sRAGE transgenic mice,and apply proteomic methods to detect the types and levels of protein expression in myocardial tissue.Results Compared with the I/R+sRAGE KIfl/fl group,the I/R+sRAGE CKI group had 59 upregulated proteins and 42 downregulated proteins in myocardial tissue.The volcano plot showed that the significantly upregulated proteins were lghg1,lgh2b,Mcm7,and Nifk,and the significantly downregulated proteins were Abca7,Colla2,Ablim1,Crebrf,and Kcp,respectively.The subcellular localization results showed that the proteins with significant changes were mainly distributed in the nucleus,cytoplasm,extracellular space,plasma membrane,endoplasmic reticulum,cytoskeleton,and others.The results of functional enrichment showed that the significantly changed proteins were mainly involved in regulating signal transduction,cell motility,metabolism,infectious diseases,tumors and the immune system.Conclusion sRAGE can inhibit myocardial I/R injury by increasing or decreasing target proteins involved in regulating intracellular and extracellular signal transduction processes following myocardial I/R.

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 investigate and analyze the risk factors of cardiovascular events by low density lipoprotein cholesterol (LDL-C). Methods A total of 430 patients with stable angina pectoris (SAP) in the hospital were included from June 2021 to June 2024 for retrospective analysis. According to whether acute myocardial infarction (AMI) occurred, the enrolled patients were divided into stable group (n=257) and deteriorating group (n=173). The general data were compared between groups, and the risk factors affecting AMI in SAP patients were analyzed. The predictive value of the above risk factors on predicting AMI in SAP patients was analyzed. Results Compared with the stable group, the levels of LDL-C, TG, LP-a and Hcy in the deteriorating group were higher (t=4.033, P<0.001; t=4.104, P<0.001; t=6.342, P<0.001; t=4.883, P<0.001) while the HDL-C level was lower (t=5.129, P<0.001). Multivariate logistic regression analysis suggested that the elevated levels of LDL-C, TG, LP-a and Hcy were the risk factors of AMI in SAP patients (P<0.05), and the elevated level of HDL-C was a protective factor (P<0.05). In the ROC curve, the area under the curve (AUC), sensitivity and specificity of combination of LDL-C, HDL-C, TG, LP-a and Hcy in predicting AMI in SAP patients were 0.777, 63.01% and 81.71%. Conclusion LDL-C is a risk factor of AMI in SAP patients. Combination of HDL-C, TG, LP-a and Hcy has certain value on predicting AMI in SAP patients.

Objective:To analyze the risk factors for aspiration pneumonia (AP) among stroke survivors with dysphagia and construct a prediction model.Methods:The records of one hundred and forty-eight stroke survivors with dysphagia admitted since 2021 were retrospectively analyzed. They were divided into an AP group ( n=46) and a non-AP group ( n=102). Univariate and multivariate logistic regressions were evaluated seeking independent risk factors for AP. the receiver-operating characteristic (ROC) curves were used to analyze predictive power. Results:The incidence of AP was 31%. Multivariate logistic regression analysis showed that age, Barthel index, Kubota′s water drinking test grading, nutritional support methods and the neutrophil/lymphocyte ratio (NLR) could be useful independent predictors of AP. The areas under the ROC curves suggested that Kubota grading, nutritional support methods, the NLR and the Barthel index could be used to prepare a prediction nomogram with good sensitivity and specificity.Conclusions:Age, Barthel index, Kubota water drinking test grades, nutritional support methods and NLR are independent predictors of AP for stroke survivors with dysphagia. Combining them in a nomogram gives better predictive power than using the factors alone.

Objective:To study the epidemiological and genetic characteristics of coxsackievirus B3 (CVB3) circulating in Guangdong Province from 2008 to 2021.Methods:This study collected the specimens of hand, foot, and mouth disease (HFMD) cases from 2008 to 2021 that were positive for other enteroviruses except for enterovirus 71 (EV71), coxsackievirus A16 (CVA16), and CVA6, as well as the specimens of herpangina and neonatal infection cases from 2020 to 2021. Enteroviruses in these specimens were detected and their types were identified. CVB3 strains were isolated and the entire VP1 sequences of CVB3 strains were amplified and sequenced. The genetic features of CVB3 strains were analyzed using DNAStar 7.1 and MEGA 6.06 software packages.Results:Among 3 484 HFMD cases positive for other enteroviruses from 2008 to 2021, CVB3-positive cases accounted for 1.6% (57/3 484); among 560 cases of herpangina from 2020 to 2021, CVB3-positive cases accounted for 2.1% (12/560); one neonatal infection case in 2021 was positive for CVB3. CVB3-positive cases accounted for 67.1% (47/70) in 2021 and 18.6% (13/70) in 2020, while there were less than five cases in other years. Forty-eight CVB3 strains were isolated and the entire VP1 sequences of 26 CVB3 strains were obtained. Phylogenetic analysis indicated that the CVB3 strains could be divided into eight genotypes (A-H) and the strains of genotypes A, D and E were prevalent in the Chinese mainland. The 26 CVB3 strains isolated in Guangdong Province shared 80.2%-100.0% nucleotide homology, and belonged to two genotypes of D and E, with genotype D prevalent from 2008 to 2017 and genotype E prevalent from 2020 to 2021.Conclusions:CVB3 is prevalent sporadically in Guangdong Province from 2008 to 2017, but the epidemic intensity increased during 2020 and 2021. CVB3 strains of genotypes D and E are prevalent in Guangdong Province during 2008 to 2021, with genotype E being the prevalent genotype during 2020 and 2021.

Objective:To analyze the laboratory test results of two outbreaks of neonatal enterovirus infections in Guangdong Province in 2019 and the genetic characteristics of Echo11, aiming to provide reference for the prevention and control of neonatal enterovirus infections.Methods:The pathogenic specimens of neonatal cases suspected of enterovirus infection were collected. Fluorescence quantitative PCR and sequencing were used for enterovirus typing and identification, and virus isolation was carried out for positive specimens.The complete sequences of VP1 of Echo11 were amplified and sequenced and the phylogenetic analysis was performed using the bioinformatics software such as Danstar6, Bioedit7.09 and MEGA6.06.Results:A total of 93 specimens from 36 neonatal cases were collected. After identification, 55 specimens from 24 cases were positive for enterovirus, of which 23 cases were positive for Echo11 and one case was positive for Coxsackievirus B4(CVB4). A total of 29 enterovirus strains were isolated from the specimens of 19 cases, of which 28 were Echo11 from 18 cases, and one was CVB4. Phylogenetic analysis revealed that the nucleotide homology between the 18 strains of Echo11 in this study was 98.2%-100.0%, and the nucleotide homology between the Echo11 strains causing the two neonatal infections was 99.7%-100.0% and 99.8%-100.0%, respectively. Echo11 could be divided into six genotypes as A, B, C, D, E and F, in which genotype A and genotype C were further divided into A1-5 and C1-4, and genotype D could be divided into D1-5. The 18 strains of Echo11 in this study were all subtype D5.Conclusions:In 2019, two outbreaks of neonatal infections in medical institutions in Guangdong Province were caused by Echo11, which belonged to the genotype D5.
