Transcatheter adrenal artery embolization(TAAE)is a minimally-invasive interventional treatment for adrenal diseases.Perioperative pain occurs mainly during and after operation.The standardized management of perioperative pain can reduce the occurrence of intraoperative adverse reactions,improve the degree of intraoperative cooperation,better the postoperative quality of life,thus,to improve patient satisfaction with interventional surgery.However,current researches among the healthcare staff mainly focus on the safety and efficacy of TAAE while neglect the standardized pain management during the perioperative period.Therefore,in order to improve the surgical efficacy of TAAE and optimize the perioperative surgical experience of patients,it is necessary to formulate a standardized pain management strategy and to apply this strategy in clinical practice.This paper aims to make a comprehensive review about the current situation of perioperative pain occurrence and pain management strategies in TAAE therapy,so as to provide reference for standardizing the perioperative pain management of interventional surgery,and improving the success rate of interventional surgery as well as the patient satisfaction with the treatment.(J Intervent Radiol,2024,33:679-683)

Objective To detect the levels of anti-soluble liver antigen(anti-SLA)antibodies in the serum of patients with autoim-mune hepatitis(AIH)and analyze their value in liver injury.Methods A retrospective analysis was conducted on 33 AIH patients with anti-SLA antibody-positive and 33 age-and sex-matched anti-SLA antibody-negative AIH cases diagnosed at Nanjing Second Hos-pital from January 2017 to April 2024.The general and clinical data of the patients were collected along with the detection of anti-SLA antibody(by protein immunoblotting),anti-nuclear antibodies(by indirect immunofluorescence)and other autoimmune liver disease-related autoantibodies,the biochemical parameters,e.g.,total bilirubin(T-Bil),alanine aminotransferase(ALT),aspartate amin-otransferase(AST),gamma-glutamyl transferase(GGT),alkaline phosphatase(ALP),and the level of immunoglobulin IgG.The clinical characteristics,laboratory parameters,and liver histopathological features of the patients were analyzed and compared.Results There were no statistically significant differences were observed in gender,age,autoimmune liver disease-related antibodies(such as antinuclear antibody,anti-smooth muscle antibody,etc.)and liver function parameters(AST,ALT,GGT and ALP),between the two groups of patients(P＞0.05).However,in the patients with positive anti-SLA antibodies,the levels of T-Bil and IgG in serum were significantly higher than those of the negative group with both P value less than 0.05(P values of 0.017 and 0.048,respectively).The pathological examination for liver tissue revealed that the proportion of the patients with lymphocyte-plasma cell infiltration in anti-SLA-positive group was significantly higher than that in anti-SLA-negative group(χ2=4.243,P＜0.05),suggesting more active immune re-sponse.Conclusion The detection of anti-SLA antibodies levels in the serum of AIH patients may reflect the extent of liver injury,and should have the potential for assisting diagnosis and monitoring the disease condition.

Berlin became the focal point for innovation in breast cancer treatment at the European Society for Medical Oncology Breast Cancer(ESMO BC)Annual Meeting held in May 2024.The conference showcased the latest advancements in breast cancer treatment,in-cluding innovative therapies and strategies.Notably,research on cyclin-dependent kinase 4 and 6(CDK4/6)inhibitors combined with endo-crine therapy(ET)in the neoadjuvant treatment of early breast cancer,though not yet reaching its primary endpoint,suggests further re-search is needed in this area.The combination of CDK4/6 inhibitors with ET continues to be the standard adjuvant therapy for high-risk pa-tients,with abemaciclib showing consistent preliminary benefits in a subgroup of patients with germline BRCA1/2 mutations.Although ri-bociclib's adverse reactions can be managed,its use requires close monitoring.New selective CDK4 inhibitors,AKT inhibitors,antibody-drug conjugates,and immunotherapies offer additional treatment alternatives for patients with advanced breast cancer.This year's meeting showcased advancements in breast cancer treatment and provides new perspectives for future research directions and patient treatment strategies.This article overviews the critical research developments presented at the meeting.

ObjectiveTo investigate the risk factors for pulmonary fungal infection in lung cancer patients， construct and validate a risk prediction model using available clinical data to predict the risk of pulmonary fungal infections in patients with lung cancer. MethodsWe conducted a retrospective study and collected information of 390 lung cancer patients treated at Zhongshan People's Hospital from January 2021 to March 2023. Demographic and clinical characteristics of the patients with and without pulmonary fungal infections were used to construct column line graphs to predict the occurrence of pulmonary fungal infections. All enrolled patients were randomly assigned to training set and internal validation set in the ratio of 7：3. For the modelling group， LASSO regression was applied to screen variables and select predictors， and multivariate logistic regression with a training set was used to construct the Noe column line graph model. The judgment ability of the model was determined by calculating the area under the curve （AUC）， and in addition， calibration analysis and decision curve analysis （DCA） were performed on the model. ResultsLASSO regression identified 14 potential predictive factors， and further logistic regression analysis showed that hepatic injury， surgery， anemia， hypoalbuminemia， illness course， invasive operation， hospital stay at least 2 weeks and glucocorticoid used for at least 2 weeks were independent predictors for the occurrence of pulmonary fungal infection in lung cancer patients. A predictive model was established based on these variables， with an AUC95%CI of 0.980 （0.973， 0.896） for the training set and an AUC95%CI of 0.956 （0.795， 1.000） for internal validation， indicating high discriminative ability. The calibration curves for both the training set and validation set were distributed along the 45°line， and the decision curve analysis （DCA） showed net benefit for threshold probabilities greater than 0.03. ConclusionsThe construction and validation of a predictive model for the risk of lung fungal infections in lung cancer patients will help clinical practitioners to identify high-risk groups and give timely intervention or adjust treatment decisions.

BACKGROUND: Studies have shown that the incidence and severity of corona virus disease 2019 (COVID-19) in patients with lung cancer are higher than those in healthy people. At present, the main anti-tumor treatments for lung cancer include surgery, immunotherapy, chemotherapy, radiotherapy, targeted therapy and anti-angiogenesis therapy. While the effects of different anti-tumor treatments on the occurrence and severity of COVID-19 pneumonia are not uniform. Therefore, we aimed to describe clinical characteristics and antitumor therapy of patients with lung cancer and COVID-19 pneumonia, and examined risk factors for severity in this population. METHODS: From December 1, 2022 to February 15, 2023, a retrospective study was conducted in 217 patients diagnosed with COVID-19 and pathologically confirmed lung cancer in the Jinling Hospital. We collected data about patients' clinical features, antitumor treatment regimen within 6 months, and the diagnosis and treatment of COVID-19. Risk factors for occurrence and severity of COVID-19 pneumonia were identified by univariable and multivariable Logistic regression models. RESULTS: (1) Among the 217 patients included, 51 (23.5%) developed COVID-19 pneumonia, of which 42 (82.4%) were classified as medium and 9 (17.6%) were classified as severe; (2) Univariate and multivariate analysis revealed overweight (OR=2.405, 95%CI: 1.095-5.286) and intrapulmonary focal radiotherapy (OR=2.977, 95%CI: 1.071-8.274) are risk factors for increasing occurrence of COVID-19 pneumonia, while other therapies are not; (3) Chronic obstructive pulmonary disease (COPD) history (OR=7.600, 95%CI: 1.430-40.387) was more likely to develop severe pneumonia and anti-tumor therapies such as intrapulmonary focal radiotherapy, chemotherapy, targeted therapy and immunotherapy did not increase severity. CONCLUSIONS Intrapulmonary focal radiation therapy within 6 months increased the incidence of COVID-19 pneumonia, but did not increase the severity. However, there was no safety concern for chemotherapy, targeted therapy, surgery and immunotherapy.

Objective To investigate the impact of lncRNA DSCAM-AS1 on the malignant biological behaviors of thyroid cancer(TC)cells by regulating the miR-150-5p/BRAF axis.Methods The expression of DSCAM-AS1 in TC cells was detected by qRT-PCR,and the best intervention cell line was screened.;the relationship between DSCAM-AS1,BRAF and miR-150-5p targeting regulation was verified by FISH,pull down and double Luciferase reporter gene experiment;The proliferation,migration and invasion of SW579 cells were detected;Western blot was applied to detect the expression of BRAF,E-Cadherin,and vimentin proteins;the tumor formation experiment in mice was applied to verify the effect of DSCAM-AS1 on TC tumor growth.Results DSCAM-AS1 was highly expressed in TC tissue and cells(P<0.05);There is a targeted regulation relationship between DSCAM-AS1,BRAF and miR-150-5p;inhibition of DSCAM-AS1 expression or overexpression of miR-150-5p obviously inhibited the proliferation,migration,invasion,and EMT of SW579 cells(P<0.05);Inhibition of miR-150-5p expression or overexpression of BRAF reversed the inhibitory effect of inhibition of DSCAM-AS1 expression or overexpression of miR-150-5p on the malignant behavior of SW579 cells(P<0.05);in vivo experiments showed that inhibiting the expression of DSCAM-AS1 obviously inhibited the growth of transplanted tumors in mice(P<0.05).Conclusion DSCAM-AS1 is up-regulated in TC cells,inhibiting the expression of LncRNA DSCAM-AS1 can inhibit the malignant progression of TC by regulating the miR-150-5p/BRAF signaling axis.

Variations in the dynein axonemal heavy chain gene, dynein axonemal heavy chain 6 (DNAH6), lead to multiple morphological abnormalities of the flagella. Recent studies have reported that these deficiencies may result in sperm head deformation. However, whether DNAH6 is also involved in human acrosome biogenesis remains unknown. The purpose of this study was to investigate DNAH6 gene variants and their potential functions in the formation of defective sperm heads and flagella. Whole-exome sequencing was performed on a cohort of 375 patients with asthenoteratozoospermia from the First Affiliated Hospital of Anhui Medical University (Hefei, China). Hematoxylin and eosin staining, scanning electron microscopy, and transmission electron microscopy were performed to analyze the sperm morphology and ultrastructure. Immunofluorescence staining and Western blot analysis were conducted to examine the effects of genetic variants. We identified three novel deleterious variants in DNAH6 among three unrelated families. The absence of inner dynein arms and radial spokes was observed in the sperm of patients with DNAH6 variants. Additionally, deficiencies in the acrosome, abnormal chromatin compaction, and vacuole-containing sperm heads were observed in these patients with DNAH6 variants. The decreased levels of the component proteins in these defective structures were further confirmed in sperm from patients with DNAH6 variants using Western blot. After intracytoplasmic sperm injection (ICSI) treatment, the partner of one patient with a DNAH6 variant achieved successful pregnancy. Overall, novel variants in DNAH6 genes that contribute to defects in the sperm head and flagella were identified, and the findings indicated ICSI as an effective clinical treatment for such patients.

Objectives To analyze the risk factors and their predictive value for postoperative hypoxemia in Type-A aortic dissection(TAAD).Methods A single-center retrospective study was conducted among 146 consecutive patients diagnosed as TAAD and undergone aortic arch surgery from January 2018 to June 2021 in Nanfang Hospital of Southern Medical University.According to the lowest postoperative PaO2/FiO2 ratio within 24 hours,the patients were classified into two groups:hypoxemia group(PaO2/FiO2≤200 mmHg)and non-hypoxemia group(PaO2/FiO2>200 mmHg).The difference of preoperative oxygen index,duration of mechanical ventilation and mortality in hospital were analyzed between the two groups.The independent risk factors for postoperative hypoxemia were evaluated by multivariate logistic regression and the predictive value was analyzed by receiver operator character(ROC)curves.Results For TAAD patients,the incidence of postoperative hypoxemia was 45.9%.Compared to non-hypoxemia group,hypoxemia group exhibited longer duration of mechanical ventilation(P<0.001)and longer intensive care unit(ICU)length of stay(P<0.05).Moreover,patients with hypoxemia presented higher mortality during hospital(P=0.011).Multivariate regression analysis identified BMI as independent risk factor(OR=1.701,P<0.001)and preoperation PaO2/FiO2 ratio as protective factors for postoperative hypoxemia in patients with TAAD(OR=0.987,P=0.004).Area under the ROC curve of BMI was 0.848,the optimal cut-off point of BMI was 25.8 kg/m2.Area under the ROC curve of pre-operation PaO2/FiO2 ratio was 0.808,the optimal cut-off point of preoperation PaO2/FiO2 ratio was 265 mmHg.Conclusions BMI higher than 25.8 kg/m2 is an independent risk factor and preoperation PaO2/FiO2 ratio higher than 265 mmHg is a protective factor for postoperative hypoxemia in patients with TAAD.Subjects with hypoxemia had longer duration of mechanical ventilation,ICU stay and higher mortality.
