Objective: To investigate the self-monitoring blood pressure behavior and its influencing factors among residents in Jiangsu Province, so as to provide the basis for strengthening proactive blood pressure monitoring among residents. Methods: Permanent residents aged 35-75 years in six counties (cities, districts), Jiangsu Province, were selected using the stratified cluster sampling method in 2023. Data on basic information, disease history, and self-monitoring blood pressure behavior were collected, height and weight were measured to calculate the body mass index (BMI); and blood glucose and lipid levels were measured. Self-monitoring blood pressure behavior was defined as having measured blood pressure at least once in the past three months. Factors affecting self-monitoring blood pressure behavior were identified using a multivariable logistic regression model. Results: A total of 12 475 residents were surveyed, including 5 748 males and 6 727 females, with a male-to-female ratio of 1∶1.17. There were 3 855 residents aged 45-<55 years (30.90%) and 5 511 residents who had self-monitoring blood pressure behaviors (44.18%). Multivariable logistic regression analysis showed that the residents who were males (OR=1.167, 95%CI: 1.081-1.261), lived in rural areas (OR=1.430, 95%CI: 1.321-1.547), aged 45-75 years (45-<55 years, OR=1.384, 95%CI: 1.241-1.543; 55-<65 years, OR=1.397, 95%CI: 1.243-1.570; 65-75 years, OR=1.196, 95%CI: 1.049-1.363), had an annual household income ≥30 000 yuan (30 000-<60 000 yuan, OR=1.190, 95%CI: 1.072-1.321; 60 000-<110 000 yuan, OR=1.330, 95%CI: 1.191-1.485; ≥110 000 yuan, OR=1.746, 95%CI: 1.536-1.984), were overweight (OR=1.170, 95%CI: 1.070-1.280) or obese (OR=1.248, 95%CI: 1.120-1.391), were unaware (OR=1.221, 95%CI: 1.103-1.353) or aware (OR=3.937, 95%CI: 3.575-4.335) of having hypertension, were aware of having diabetes (OR=1.538, 95%CI: 1.354-1.749), and aware of having dyslipidemia (OR=1.265, 95%CI: 1.106-1.447) were more likely to have self-monitoring blood pressure behaviors. Conclusions Among the residents aged 35-75 years in Jiangsu Province, 44.18% had self-monitoring blood pressure behavior. Gender, place of residence, age, annual household income, BMI, hypertension, diabetes, and dyslipidemia were identified as influencing factors for self-monitoring blood pressure behavior.

Neuroblastoma is the most common extracranial solid tumor in children. The prognosis of different stages varies greatly, and its risk staging system is completely based on imaging. Radionuclide imaging plays an important role in the diagnosis and staging of various tumors, and it is also of great significance in the early diagnosis and staging of neuroblastoma. At present, imaging agents used for neuroblastoma mainly include catecholamine receptor, glucose metabolism, somatostatin receptor, etc. This article mainly discusses the application value and research progress of these imaging agents in the diagnosis of neuroblastoma.

Objective:To compare and choose the best method for measuring metabolic tumor volume (MTV) of nasal extranodal natural killer/T-cell lymphoma (ENKTL), evaluate the prognostic value of 18F-FDG PET/CT metabolic parameters and clinical staging/scoring systems for patients with nasal ENKTL, and explore the added value of the two combinations for prognostic prediction. Methods:From January 2016 to September 2022, 44 patients (26 males, 18 females; age (47.5±13.6) years) pathologically diagnosed with nasal ENKTL who underwent 18F-FDG PET/CT imaging before treatment in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively collected. SUV 2.5, SUV 4.0 and 41%SUV max were used as thresholds to measure MTV and total lesion glycolysis (TLG), and the consistency was analyzed by Bland-Altman analysis. The ROC curve analysis was used to compare the prognostic efficiency of different methods and determine the best method. The prognostic values of different clinical factors and clinical staging/scoring systems between groups were evaluated by corrected χ2 test. The independent factors were screened by Cox-regression model, and the combined diagnosis model was constructed by logistic regression. Results:Of 44 patients, 6(13.6%) were dead, with the overall survival (OS) of 32.05(11.77, 64.43) months, and the 2-year and 5-year OS rates of 86.6% and 82.5%, respectively. The mortality of different groups in age (≥60 and <60 years), prognostic index of natural killer cell lymphoma (PINK) score (low- and high-risk), and international prognostic index (IPI) score (low- and high-risk) were significantly different ( χ2 values: 5.02, 4.12, 3.88, all P<0.05). The consistency of MTV measured by different thresholds was good. Among them, the MTV measured by threshold of SUV 2.5 had the highest predictive efficiency with the AUC of 0.737. Multivariate analysis showed that MTV (hazard ratio ( HR)=10.488, 95% CI: 1.864-59.026, P=0.008) was the independent influencing factor of OS. By removing other factors, minimization model was obtained, including MTV and PINK score ( P values: 0.006, 0.048). The prediction model of MTV combined with PINK score improved prognostic efficacy with the AUCs of MTV, PINK score and the combination model of 0.781, 0.741 and 0.912, respectively. Conclusions:MTV measured by threshold of SUV 2.5 has better prognostic predictive value. MTV is the independent prognostic factor for OS in nasal ENKTL patients. MTV combined with PINK score has better prognostic value.

The intestine is the main site of oral drug absorption, and the epithelial cells of the intestine contain villi and microvilli, which promote secretion, cell adhesion, and absorption by increasing surface area and other factors. Traditional two-dimensional/three-dimensional (2D/3D) cell culture models and animal models have played an important role in studying drug absorption, but their application is limited due to the lack of sufficient predictability of human pharmacokinetics or ethical issues, etc. Therefore, mimicking the core structure and key functions of the human intestine based on in vitro live cells has been the focus of research on constructing a microfluidic chip-based intestinal model. The model is a microfluidic chip bionic system that simulates the complex microstructure, microenvironment, and physiological functions of the human intestine using microfabrication technology. Compared with 2D cell culture and animal experiments, the intestinal microarray model can effectively simulate the human in vivo environment and is more specific in drug screening. The research progress and applications in disease modeling, drug absorption and transport of intestinal microarray models and intestine-related multi-organ coupled microarray models at home and abroad were reviewed in this paper. The current challenges of intestinal chip simulating intestinal homeostasis and diseases were summarized，in order to provide reference for the further establishment of a more reliable in vitro intestinal chip model.

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 Visual electrophysiology and optical correlation tomography angiography(OCTA)were used to investigate differences in preoperative retinal function in patients with type 2 diabetic cataract(DC)without obvious retinopathy(NDR)and to determine the clinical application of whole-process blood glucose man-agement(WBGM)for improving postoperative vision in DC patients.Methods This study investigated the preop-erative and postoperative visual electrophysiology(N75,P100,photopic FERG,and scotopic FERG),peripapil-lary retinal nerve fiber layer(pRNFL)and peripapillary capillary vessel density(ppVD)data,as well as trends in these data changes during blood glucose management intervention.Results As the course of T2DM progressed,FBG and HbA1c increased,the N75 and P100 lategraduancy periods of patients gradually lengthened,and the photopic FERG,scotopic FERG,pRNFL,and ppVD values decreased at each postoperative time point.At the same time,the best corrected visual acuity(BCVA)of patients after surgery gradually decreased(P<0.05).Compared with that at 1 week after surgery,the BCVA of Group A(without whole-process blood glucose manage-ment)gradually increased at 1 month and 3 months after surgery but showed a downward trend at 1 year after sur-gery.The BCVA of Group B(with whole-process blood glucose management)gradually stabilized at 1 month after surgery,and at all time points after surgery,the BCVA of Group B was better than that of Group A.The results showed that N75 and P100 in Group A were greater than those in Group B,while the photopic and scotopic FERG,pRNFL,and ppVD(%)in Group A were lower than those in Group B.In addition,N75 and P100 in Group A showed a gradual prolongation trend at various time points after surgery,while photopic FERG,scotopic FERG,pRNFL,and ppVD(%)showed a gradually decreasing trend.However,the above data in Group B gradu-ally stabilized at 3 months after DC surgery,approaching the preoperative level of the group(P<0.05).In the state of whole blood glucose management,although N75 and P100 both reached their longest durations at 1 week af-ter surgery,N75,P100,photopic FERG,scotopic FERG,and pRNFL showed a gradually decreasing trend at 1 month and 3 months after surgery,while ppVD(%)gradually increased(P<0.05).At various time points from 3 months to 1 year after surgery,the overall trend of the above indicators remained stable and close to the preoperative values(P>0.05).Conclusion According to the results of the quantitative analysis of visual electrophysiology and OCTA,in DC patients without obvious retinopathy and with the worsening of diabetes,retinal function decreased,but whole-process blood glucose management effectively restored retinal function and improved visual quality after surgery.
