In recent years, the number of lung surgeries has increased year by year, and the number of patients with postoperative cough has also increased gradually. Chronic cough after lung surgery seriously affects patients' quality of life and surgical outcome, and has become one of the clinical problems that clinicians need to solve. However, there is currently no guideline or consensus for the treatment of chronic cough after lung surgery in China, and there is no standardized treatment method. Therefore, we searched databases such as PubMed, Web of Science, CNKI, and Wanfang databases ect. from 2000 to 2023 to collected relevant literatures and research data, and produced the first expert consensus on chronic cough after lung surgery in China by Delphi method. We gave 11 recommendations from five perspectives including timing of chronic cough treatment, risk factors (surgical method, lymph node dissection method, anesthesia method), prevention methods (preoperative, intraoperative, postoperative), and treatment methods (etiological treatment, cough suppressive drug treatment, traditional Chinese medicine treatment, and postoperative physical therapy). We hope that this consensus can improve the standardization and effectiveness of chronic cough treatment after lung surgery, provide reference for clinical doctors, and ultimately improve the quality of life of patients with chronic cough after lung surgery.

Background and objective Chronic cough after pulmonary resection is one of the most common complications,which seriously affects the quality of life of patients after surgery.Therefore,the aim of this study is to explore the risk factors of chronic cough after pulmonary resection and construct a prediction model.Methods The clinical data and postoperative cough of 499 patients who underwent pneumonectomy or pulmonary resection in The First Affiliated Hospital of University of Science and Technology of China from January 2021 to June 2023 were retrospectively analyzed.The patients were randomly divided into training set(n=348)and validation set(n=151)according to the principle of 7:3 randomization.According to whether the patients in the training set had chronic cough after surgery,they were divided into cough group and non-cough group.The Mandarin Chinese version of Leicester cough questionnare(LCQ-MC)was used to assess the severity of cough and its impact on patients'quality of life before and after surgery.The visual analog scale(VAS)and the self-designed numerical rating scale(NRS)were used to evaluate the postoperative chronic cough.Univariate and multivariate Logistic regression analysis were used to analyze the independent risk factors and construct a model.Receiver operator characteristic(ROC)curve was used to evaluate the discrimination of the model,and calibration curve was used to evaluate the consistency of the model.The clinical application value of the model was evaluated by decision curve analysis(DCA).Results Multivariate Logistic analysis screened out that preoperative forced expiratory volume in the first second/forced vital capacity(FEV1/FVC),surgical procedure,upper mediastinal lymph node dissection,subcarinal lymph node dissection,and postoperative closed tho-racic drainage time were independent risk factors for postoperative chronic cough.Based on the results of multivariate analysis,a Nomogram prediction model was constructed.The area under the ROC curve was 0.954(95％CI:0.930-0.978),and the cut-off value corresponding to the maximum Youden index was 0.171,with a sensitivity of 94.7％and a specificity of 86.6％.With a Bootstrap sample of 1000 times,the predicted risk of chronic cough after pulmonary resection by the calibration curve was highly consistent with the actual risk.DCA showed that when the preprobability of the prediction model probability was be-tween 0.1 and 0.9,patients showed a positive net benefit.Conclusion Chronic cough after pulmonary resection seriously af-fects the quality of life of patients.The visual presentation form of the Nomogram is helpful to accurately predict chronic cough after pulmonary resection and provide support for clinical decision-making.

Background and objective Cough is one of the main complications after pulmonary surgery,which seriously affects the postoperative quality of life.Preserving the pulmonary branch of vagus nerve may reduce the incidence of postoperative cough.Therefore,the aim of this study was to investigate whether preserving the pulmonary branch of the vagus nerve could reduce the incidence of postoperative chronic cough in patients with stage I peripheral lung adenocarcinoma.Methods A total of 125 patients who underwent single-port thoracoscopic radical resection for lung cancer in the Depart-ment of Thoracic Surgery,The First Affiliated Hospital of University of Science and Technology of China from June 2022 to June 2023 were retrospectively selected,and divided into two groups according to whether the vagopulmonary branch was preserved during the operation,namely,the vagopulmonary branch group(n=61)and the traditional group(n=64).The general clinical data,perioperative conditions,lymph node dissection,Mandarin Chinese version of The Leicester Cough Questionnaire(LCQ-MC)scores before and 8 weeks after operation were recorded in the two groups.Both the two groups were divided into tamponade group and non-tamponade group according to whether autologous fat or gelatin sponge was tamponade after lymph node dissection.LCQ-MC scores and postoperative chronic cough of both groups were calculated.Results The LCQ-MC score of the traditional group was significantly lower than that of the vagopulmonary branch group in physiological,psychological,social and total scores at 8 weeks after surgery,and the difference was statistically significant(P<0.05).There were more cough patients in the traditional group than the vagopulmonary branch group at 8 weeks after surgery,with significant difference(P=0.006).Subgroup analysis was conducted separately for the vagopulmonary branch group and the traditional group.Among the patients in the vagopulmonary branch group and the traditional group,the LCQ-MC scores of the non-tamponade group 8 weeks after surgery were lower than those of the tamponade group(P<0.05).There were more patients with cough in the group 8 weeks after surgery than in the tamponade group(P=0.001,P=0.024).Conclusion For patients with stage I peripheral lung adenocarcinoma,the preservation of the pulmonary branch of vagus nerve is safe and effective,which can reduce the incidence of postoperative chronic cough and improve the postoperative quality of life of the patients.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective:To investigate the clinicopathological features and genetic characteristics of congenital cystic adenomatoid malformation (CCAM) of lung and CCAM associated lung cancer in adults.Methods:A total of 13 cases of CCAM of lung in adults, diagnosed from June 2015 to May 2023, were collected from the Department of Pathology, Shanghai Pulmonary Hospital, Tongji University School of Medicine, China. Their histopathological features were correlated with probable development into lung cancer. Next-generation sequencing was performed on the benign and malignant areas of all cases.Results:The pathological classification of all cases were of CCAM of lung type 1. There were 4 male and 9 female cases, age ranged from 18 to 65 years, with a mean age of 41 years. Six cases were accompanied by lung cancer, all of them were mucinous adenocarcinoma. Next-generation sequencing showed no gene mutation in 2 of the 13 cases; KRAS mutations in exon 2 were detected in 7 cases, in which there were 6 cases complicated with lung mucinous adenocarcinoma and no matter in the malignant or benign regions, the same case exhibited the same mutation sites in KRAS gene.Conclusions:CCAM of the lung is a congenital disease, and in adults, type 1 is most commonly found in the pathological classification, and it is often accompanied by cancer. Gene mutations are frequently detected in CCAM of the lung, KRAS being the most recurrent mutation which may play an important role in the carcinogenesis.

Abstract: Objective To investigate the expression of T cell immunoglobulin and mucin domain-containing protein 3 (Tim-3) on the surface of T cells in patients with brucellosis (Bm), as well as the expression of interleukin-10 (IL-10) and transforming growth factor beta (TGF-β) in serum, and to analyze the differential expression of these indicators in patients with acute and chronic brucellosis, in order to provide new approaches for the differential diagnosis of acute and chronic brucellosis. Methods A total of 56 patients diagnosed with brucellosis at the First Affiliated Hospital of Xinjiang Medical University from April 2023 to September 2023 were selected, including 31 patients in the acute phase and 25 patients in the chronic phase. Additionally, 35 healthy individuals underwent routine physical examinations within the same period served as healthy controls. Flow cytometry was used to detect and compare Tim-3 levels on the CD4+ T cells' surface among the groups. Levels of serum IL-10 and TGF-β were measured and compared using CBA and ELISA, respectively, and the relationship of these factors with the staging of brucellosis patients was analyzed. Results The proportions of Tim-3+CD3+CD4+T cells in the control group, acute group, and chronic group were (2.56±1.25)%, (5.14±1.98)%, and (13.66±2.66)%, respectively. The Tim-3 levels in the patients with brucellosis were higher than those in the healthy control group, with the chronic group showing even higher levels, and these differences were statistically significant (P<0.05). The levels of IL-10 and TGF in the patient group were higher than those in the healthy control group, with the chronic group exhibiting significantly higher levels of IL-10 and TGF-β than the acute group, also presenting statistically significant differences (P<0.05). The areas under the ROC curve for predicting chronic brucellosis with Tim-3, IL-10, and TGF-β scores were 0.876, 0.865, and 0.663, respectively. Conclusions There are certain differences in the expression of Tim-3, serum IL-10, and TGF-β among patients with brucellosis, with high expression indicating a potential transition to the chronic phase of the disease. Tim-3 has shown the best diagnostic performance. Therefore, as a diagnostic indicator, Tim-3 may provide new ideas and strategies for the treatment and differential diagnosis of brucellosis.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

BACKGROUND: Pre-operative accuracy of subcentimeter ground glass nodules (SGGNs) is a difficult problem in clinical practice, but there are few clinical studies on the benign and malignant prediction model of SGGNs. The aim of this study was to help identify benign and malignant lesions of SGGNs based on the imaging features of high resolution computed tomography (HRCT) and the general clinical data of patients, and to build a risk prediction model. METHODS: This study retrospectively analyzed the clinical data of 483 patients with SGGNs who underwent surgical resection and were confirmed by histology from the First Affiliated Hospital of University of Science and Technology of China from August 2020 to December 2021. The patients were divided into the training set (n=338) and the validation set (n=145) according to 7:3 random assignment. According to the postoperative histology, they were divided into adenocarcinoma group and benign lesion group. The independent risk factors and models were analyzed by univariate analysis and multivariate Logistic regression. The receiver operator characteristic (ROC) curve was constructed to evaluate the model differentiation, and the calibration curve was used to evaluate the model consistency. The clinical application value of the decision curve analysis (DCA) evaluation model was drawn, and the validation set data was substituted for external verification. RESULTS: Multivariate Logistic analysis screened out patients' age, vascular sign, lobular sign, nodule volume and mean-CT value as independent risk factors for SGGNs. Based on the results of multivariate analysis, Nomogram prediction model was constructed, and the area under ROC curve was 0.836 (95%CI: 0.794-0.879). The critical value corresponding to the maximum approximate entry index was 0.483. The sensitivity was 76.6%, and the specificity was 80.1%. The positive predictive value was 86.5%, and the negative predictive value was 68.7%. The benign and malignant risk of SGGNs predicted by the calibration curve was highly consistent with the actual occurrence risk after sampling 1,000 times using Bootstrap method. DCA showed that patients showed a positive net benefit when the predictive probability of the predicted model probability was 0.2 to 0.9. CONCLUSIONS Based on preoperative medical history and preoperative HRCT examination indicators, the benign and malignant risk prediction model of SGGNs was established to have good predictive efficacy and clinical application value. The visualization of Nomogram can help to screen out high-risk groups of SGGNs, providing support for clinical decision-making.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

Cardiac magnetic resonance (CMR) imaging provides accurate anatomic information and advanced soft contrast, making it the reference standard for assessing cardiac volumes and systolic function. In this review, we summarize the recent advances in CMR sequences. New technical development has widened the use of CMR imaging beyond the simple characterization of myocardial scars and assessment of contractility. These novel CMR sequences offer comprehensive assessments of coronary plaque characterization, myocardial fiber orientation, and even metabolic activity, and they can be readily applied in clinical settings. CMR imaging is able to provide new insights into understanding the pathophysiologic process of underlying cardiac disease, and it can help physicians choose the best treatment strategies. Although several limitations, including the high cost and time-consuming process, have limited the widespread clinical use of CMR imaging so far, recent advances in software and hardware technologies have made the future more promising.
