Objective To understand the surveillance situation of poliovirus in Guangzhou from 2011 to 2024, and to further strengthen polio surveillance and ensure the continued maintenance of a polio-free status. Methods An analysis was conducted on the discovery and investigation results of six cases of vaccine-derived poliovirus (VDPV) detected in Guangzhou. Results A total of 6 VDPV incidents were reported in Guangzhou from 2011 to June 2024, among which 5 incidents were from sewage sample testing in the Liede Sewage Treatment Plant in Guangzhou, all of which were confirmed as VDPV, with 1 for type I, 1 for type II, and 3 for type III. In addition, one confirmed HFMD case was identified as a type VDPV II carrier. No presence of any wild poliovirus (WPV), VDPV cases, or circulating VDPV (cVDPV) was reported. Conclusion Guangzhou City has maintained a high level of vigilance and effectiveness in the monitoring and prevention of polio. Continuously strengthening the construction of the polio monitoring network, optimizing vaccination strategies, and comprehensively improving public health awareness are still the focus of the prevention and control work in the future.

Objective To analyze the serum 25-hydroxy vitamin D[25(OH)D]levels and vitamin D nutri-tional status of 0-14 years old children in Hangzhou,and to provide scientific basis for the prevention of vita-min D deficiency.Methods A total of 26 225 healthy children aged 0 to 14 who were tested in Hangzhou Dian Medical Diagnosis Center from January 1,2021 to December 31,2023 were selected as the study objects.The 25(OH)D levels were detected by direct chemiluminescence method,and the 25(OH)D levels and vitamin D nutritional status of children with different genders,ages and seasons were analyzed and compared.Results The level of 25(OH)D in girls was slightly higher than that in boys,and the difference was statisti-cally significant(P＜0.05).With the increase of age,the level of 25(OH)D continued to decline,and the pro-portion of vitamin D deficiency and vitamin D insufficiency gradually increased.The level of 25(OH)D was the highest in children＜3 years old and the lowest in children 10-14 years old.There was statistical significance in the proportion of vitamin D nutritional status between boys and girls aged 10 to 14(P＜0.05).In the four seasons,children's 25(OH)D level is the highest in spring and the lowest in summer.The difference of 25(OH)D level and vitamin D nutritional status in different seasons was statistically significant(P＜0.05).The proportion of vitamin D deficiency and vitamin D insufficiency in winter was higher than that in other seasons,and the difference was statistically significant(P＜0.05).Conclusion The nutritional status of vitamin D in 0-14 year old children in Hangzhou is good,but the importance of vitamin D supplementation for children should not be ignored,and active publicity and education should be carried out to prevent vitamin D deficiency.

Objective To investigate the relationship between serum forkhead box F1(FOXF1)and Ape-lin-13 levels and carotid atherosclerosis(CAS)in elderly patients with type 2 diabetes mellitus(T2DM).Methods From January 2022 to March 2024,207 elderly T2DM patients admitted to the hospital(T2DM group)and 52 healthy elderly patients underwent physical examination(control group)were selected as the study objects.The elderly T2DM patients were divided into CAS group(128 cases)and non-CAS group(79 cases)according to the occurrence of CAS.Serum FOXF1 and Apelin-13 levels were detected by real-time flu-orescent quantitative PCR and enzyme-linked immunoadsorption assay.The influencing factors of CAS in eld-erly T2DM patients were determined by multivariate unconditional Logistic regression,and the predictive effi-cacy of serum FOXF1 and Apelin-13 levels was analyzed by receiver operating characteristic curve.Results The levels of FOXF1 and Apelin-13 in T2DM group were lower than those in control group(P＜0.05).The inci-dence of CAS in 207 elderly T2DM patients was 61.84％(128/207).The levels of serum FOXF1 and Apelin-13 in CAS group were lower than those in non-CAS group(P＜0.05).The independent risk factors of CAS in elderly T2DM patients were the duration of T2DM,glycosylated hemoglobin and low density lipoprotein cho-lesterol(P＜0.05),and the independent protective factors were FOXF1 and Apelin-13(P＜0.05).The com-bined prediction of serum FOXF1 and Apelin-13 levels for CAS in elderly T2DM patients was 0.882,which was larger than 0.782 and 0.791 predicted by serum FOXF1 and Apelin-13 levels alone(P＜0.05).Conclu-sion The decrease of serum FOXF1 and Apelin-13 levels in elderly T2DM patients is closely related to CAS,and the combined detection of serum FOXF1 and Apelin-13 levels has a high predictive effect on CAS in elder-ly T2DM patients.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

Objective:To investigate the prognostic relationship between serum KL-6 level and rheumatoid arthritis(RA)combined with interstitial lung disease(RA-ILD).Methods:In Affiliated Hospital of Inner Mongolia Medical University from January 2018 to January 2021,seventy patients with RA were selected and divided into RA-ILD group(34 cases)and RA(36 cases)accord-ing to whether they were complicated with ILD,clinicopathological characteristics of the two groups of patients were analyzed by uni-variate analysis,focusing on the comparison of the expression level of KL-6 in the serum of the two groups and the correlation analysis with laboratory indexes,lung function and imaging,multivariate Logistic regression analysis risk factors affecting RA-ILD.Results:There were significant differences in gender,smoking history,age,age of onset,course of disease,DAS28,KL-6,WBC,UA,RF,anti-CCP antibody,TLC%Pred and DLCO%Pred between the two groups(P<0.05).In RA-ILD group,the proportion of clinical symp-toms was more prominent,joint pain was more prominent,and the thickening of pleural adhesion was more prominent on HRCT;Spearson correlation analysis showed that the level of serum KL-6 in RA-ILD group was significantly negatively correlated with TLC%Pred,VC%Pred and DLCO%Pred(P<0.05);there was a significant positive correlation with RF and anti-CCP antibody levels(P<0.05);there was no significant correlation with FEV1%Pred and FEV1/FVC(P>0.05);expression level of KL-6 in RA-ILD group was significantly higher than that in RA group before treatment,and there was no significant difference after treatment(P>0.05);Fol-lowed up for one year,six patients died in RA-ILD group.The expression level of KL-6 in death group was significantly higher than that in non death group(P<0.05);multivariate Logistic regression analysis showed that old age,male,smoking,increased anti CCP antibody and KL-6 were independent risk factors for RA-ILD(P<0.05);the maximum area under the ROC curve predicted by serum KL-6 was 0.802,the 95%CI was 0.743～0.866,the sensitivity was 0.853,the specificity was 0.827,and the maximum area under the ROC curve detected jointly was 0.854,indicating that the prediction ability of the model was strong.Conclusion:Serum KL-6 levels in RA-ILD patients are significantly increased.KL-6 can be used as a serological index for early detection of ILD,and combined with lung function detection can detect ILD earlier.Early diagnosis is of great significance for treatment and prognosis.

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.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Transbronchil biopsy has the characteristic of less trauma and quick recovery compared to percutaneous aspiration biopsy. In order to automate this procedure, it requires the development of a robotic surgical system that combines electromagnetic navigation and flexible endoscope. The robotic surgical system introduced herein consists of flexible endoscope, remote-control handle, electromagnetic navigation and dexterous manipulators. The robotic system supports lung bronchial model segmentation and reconstruction, automatic bronchial path planning, real-time navigation and visual biopsy. In the control of the endoscopic catheter, an elasticity compensation algorithm was proposed to improve the location accuracy of the catheter and operational efficiency. Clinical trials proved that the robotic system had high positioning accuracy, was intuitive to operate, and could improve the biopsy efficiency, shorten the learning time, reduce the burden of surgical operations, and lower radiation exposure and infection rate.
